Good morning, ladies and gentlemen, and welcome to our virtual Capital Market Day on accelerating high-value growth. My name is Eva Riesenhuber. I'm the Head of Investor Relations, and I will be your host for today. First, let's take a look at the agenda. We're going to start off the day with our CEO and President, Roland Busch, presenting accelerating high-value growth strategy. He is followed by our CFO, Ralf Thomas, who will go a deep dive into how this translates into accelerated value creation. We finish the first block of sessions with an ESG presentation by our Chief Sustainability Officer, Judith Wiese, who will walk us through our ambitious ESG target framework. We have time for a live Q&A before we go into a short break.
After the break, we come back with Digital Industries, where CEO Cedrik Neike and CFO Rudolf Basson will present the digital enterprise to you. They're accompanied by Tony Hemmelgarn, the CEO of DI Software, for a deep dive into our software business. As before, we go into live Q&A before a short break. After the break, we come back with Mobility and Smart Infrastructure. CEO Matthias Rebellius and CFO Axel Meier will present Smart Infrastructure to you, followed directly by CEO Michael Peter and CFO Karl Blaim for the Mobility business. We go into a short Q&A before a break. After the break, we have a fireside chat with the entire Siemens management board. This is very important because if during the course of the day today, we actually manage not to answer some of your questions, please do send them to us at investorrelations@siemens.com.
We will try to bundle all of these questions into the topics for the fireside chat for in which we then try and wrap up and hopefully manage to answer your questions. Now, the Capital Market Day will conclude around 3:00 P.M. with a closing remark by Roland Busch. A few more housekeeping items. This event is webcast on our Investor Relations website. A recording of this webcast will be made available on the same website as soon as we have it. Now, allow me a word on handouts. Handouts are very important to us. We will make the handouts available prior to each relevant session. For the first block of sessions, the CEO, CFO, and ESG handout is now available on our Investor Relations website. During the course of the day, in our speeches, we are not using the handout.
We are actually using technology to visualize what we're talking about. In that sense, the handout is complimentary, and it has additional information and in-depth details. Finally, I would like to draw your attention to the disclaimer and safe harbor statement on page two of each of the handouts. Because right after the ESG session, we jump into Q&A, for all our investors and analysts with a live link for direct participation, please be familiar with the dial-in instructions so we're not losing any time. Thank you so much for your patience. With that, let's kick it off and over to Roland Busch.
Thank you, Eva. Good morning, and a warm welcome to our Capital Market Day. I've been with the company for almost 30 years, and the last 10 years on the Managing Board. During that time, I've experienced many market shifts from different perspectives while working for different Siemens businesses with different countries. Nothing compares with the speed and scale of transformation that we are seeing in our markets right now. Today, I want to tell you why this is of pivotal importance for Siemens and why Siemens is uniquely positioned to accelerate high-value growth. Because we are a focused technology company addressing highly attractive growth markets with our global footprint. Because we can empower our customers to master their digital transformation and sustainability challenges with our technologies. Because we can combine the real and the digital worlds like no other company can.
We are pursuing a clear focus on profit, cash, value creation, stringent capital allocation and execution. Finally, we have the right strategy, the right team at the right time. Let's talk about our markets first. Digital transformation is imperative for our customers to achieve their level of growth and resilience. It has become a priority for companies of all sizes and in every industry. This trend is being accelerated by the pandemic. Some companies are just getting started, others are more advanced. Overall, many of our markets have low levels of automation, digitalization. The potential for their business is huge. A few examples. Take industry. 60% of manufacturing tasks can be automated. Infrastructure. Digital technologies can unlock savings potentials of up to 20% in operations. The maintenance phase of buildings, this is where 80% of their lifecycle costs occur.
In transport, digital signaling technology can increase capacity by 20% without having to build additional infrastructure. Healthcare, AI and digital twin technologies can save people's lives and reduce stroke-related costs worldwide by 50%. With our technologies, we are addressing the major challenges of our customers: productivity and efficiency, quality and availability, flexibility and time to market, and finally, resilience and sustainability. Our customers are relying on us to help them transform. Let me share some examples. We are helping Mercedes-Benz to transform their brownfield plant in Berlin into a digital, sustainable factory. Smart Infrastructure will help them to reduce the carbon footprint of their factory buildings. Digital Industries will digitalize their production processes. Because digitalization requires new skills, Siemens Advanta will support them to upskill their workforce too.
The beauty of this project is that Mercedes-Benz only needs 1 partner, and it will serve as a blueprint for their 30 plants worldwide. We are supporting Norway to transform their entire rail infrastructure. Today, they have an analog system with 11,200 signals and 330 interlockings. We are replacing this with a digital system that uses one digital interlocking and a data center instead. Together with our customer, we are creating the rail infrastructure of the future, which will enhance safety, punctuality, and capacity. In Germany, we helped BioNTech to ramp up production of their COVID-19 vaccine. We converted an existing plant with digital and automation technologies, and in record time, just five months instead of one year. This allowed BioNTech to deliver vaccine doses much faster to the market. We are also supporting GlaxoSmithKline with their digital transformation.
With our digital twin technology, we help them to reduce development time for vaccines. World leaders recognize the importance of digital transformation and sustainability for their country's future. Many governments are prioritizing a digital green recovery in their stimulus program. This creates enormous opportunities for Siemens in the years ahead. Our technology and our strong global footprint gives us a unique advantage to help countries transform their economies. Today, I would like to focus on the United States and China, two of our biggest and fastest-growing markets. The infrastructure plan of the United States includes investments to strengthen their industrial supply chains, to ensure their position as technology leader, and to decarbonize their economy. China has also prioritized building a digital and low-carbon economy in their current five-year plan.
To become a high-tech leader, they are accelerating their industrial digital transformation, and they want to become carbon neutral by 2060, reaching peak emissions before 2030. Siemens has a strong local presence in both countries that goes back over 150 years. Today in China, we have more than 60 manufacturing R&D and digital hubs and over 30,000 employees. In the U.S., we also have more than 60 hubs and over 40,000 employees. Our long-standing partnership with both countries means that we are well-positioned to help them achieve their goals. The same can be said for Europe and other countries, where we see similar dynamics and where Siemens has a strong footprint too.
With our technology portfolio, we can help countries to digitally transform manufacturing and infrastructure. We have the technologies to enable a transition to a low-carbon economy. Our technologies support customers to do more with less, to use fewer resources, to reduce their energy consumption, to lower their carbon footprint. Let me share an example. Our customer, TrakRap, supplies manufacturers of fast-moving consumer goods with solutions for recyclable packaging. With our digital twin technology, they developed a new form of wrapping that reduces plastic by 70% and energy consumption by as much as 90%. Tech is great, sometimes our customers also need financing. Siemens Financial Services helped TrakRap to implement an innovative pay-per-wrap business model for their end customers. Of course, Siemens Financial Services also supports infrastructure projects like the new Thameslink commuter line, one of the largest rail projects in the U.K.
Now I want to talk about how we are expanding our market opportunities. Siemens is focused on the industries that form the backbone of economies: manufacturing, infrastructure, transport, and healthcare. These are highly attractive markets today and in the future. Our addressable markets for Smart Infrastructure, Digital Industries, Mobility, and Siemens Healthineers amount to approximately EUR 440 billion, with growth rates of 4%-5%. I will tell you later how we are leveraging our domain knowhow and digital capabilities across all Siemens businesses to create high-value growth and to reinvent these markets. Our ambitions don't stop here. We want to grow our addressable market by entering adjacent markets that are worth about EUR 120 billion, and we have even more attractive growth rates. We are unlocking these markets through organic growth and targeted bolt-on acquisitions such as Supplyframe.
Our planned acquisition of Supplyframe will speed up our digital marketplace strategy, and it will broaden our access to the growing market of small and medium-sized companies. In the case of radiation oncology, Siemens Healthineers took a transformational step with Varian. This acquisition creates an integrated oncology solution that is unmatched in the market, and most importantly, it will help advance the global battle against cancer. We are also leveraging our core competencies to grow in adjacent markets. For example, to tap into the growing demand for digital transformation services, we launched Siemens Advanta. They offer IoT consulting and integration services. Beyond that, we are developing core technologies to drive breakthrough innovations in our markets. For example, AI, digital twin, 5G industrial edge, hydrogen solutions, charging infrastructures, and a lot more. These technologies will drive growth in the future. Let me highlight some of them.
We are already number 1 in deploying industrial 5G manufacturing, and in the future we will bring 5G to infrastructure and transport systems too. Edge computing will enable real-time decisions on the shop floor. Already today, we offer market-leading solutions for industrial edge, and we can build on our installed base of 45 million automation and drive devices. We know the demand for climate-friendly solutions will accelerate in the future. We are deploying drivetrains for hydrogen locomotives to help our rail customers reduce their carbon footprint. In another attractive growth field, electric vehicles. Forecasts expect 130 million on the road by 2030. To make this a reality, we can provide the charging infrastructure. I mentioned earlier how we are supporting Mercedes-Benz to digitalize their factory in Berlin. We are also partnering with their parent company, Daimler, to enable fleet operators to make the switch to electric mobility.
Let's hear from Ola Källenius, CEO of Daimler.
I think we all agree the transformation is here, change is happening, and that implies customer expectations keep evolving. Top of the list are two requirements: go digital and go sustainable. Both go beyond what one country or one company alone can possibly pull off, and that's why partnerships are paramount across industries and disciplines. The partnership between Siemens and Daimler isn't exactly new. We have been cooperating for more than 120 years. Looking ahead, this partnership will gain in importance as we work on some of the most fundamental transformations of our business. These include our new partnership in Berlin, where we plan to advance digital manufacturing and efficient automation in our car production using more sustainable and more energy-efficient production methods in our Mercedes-Benz plants.
Holistically, a cleaner, more sustainable energy supply across our entire operation, aiming to reach zero emissions.
Electric charging infrastructure for Daimler Truck to achieve zero-emission trucking and transportation. One thing is certain, having Siemens as a partner at our side is an important asset to achieve Daimler's ambitious goals in becoming an even better, fully digital, and holistically sustainable company. We are proud to work with customers like Daimler who are reinventing their industries. Our customers place great trust in us, and we have seen this in our excellent results for the first half of our fiscal year. This is just the beginning. We will continue to grow above market rates in our addressable markets. We will enter adjacent markets which offer higher growth rates and profitability. Altogether, we are expanding our total addressable market to more than EUR 550 billion. Now, let me tell you about our growth strategy and how we intend to accelerate high-value growth.
Quite often, the capital market asks us for proof points showing that customers buy software as well as automation solutions from us. It is a good question, but it doesn't go far enough. We can do much more than that. We can accelerate high-value growth by creating additional value for our customers, creating new business models, tearing down silos between the markets, expanding into new markets, expanding our customer base. We can do this by combining the real and digital worlds. This is the foundation of our growth strategy. Our core business and our digital business reinforce each other in a virtual cycle. We will grow our core business by leveraging our digital capabilities, and in turn, we will grow our digital business by leveraging our core business and domain know-how. This will result in profitable revenue growth above market rates.
Let me share some examples of how we can grow our core business through our digital expertise. The Rhine-Ruhr Express was built to ease congestion in Germany's largest metropolitan area. This is one of the biggest orders we have ever received for regional rail transport in Germany. 82 trains, 32 years maintenance in a €1.7 billion contract. Why did the customer choose Siemens over other suppliers? Because we can perform predictive service. We could guarantee 99.9% availability with lower CapEx requirements. That means our customers can provide a full service using fewer trains. Our digital offering was a key differentiator to secure this order, and we can scale up. London's Piccadilly line is next. Here we are delivering 94 trains and digital services in a contract worth €1.5 billion. There are further opportunities to supply more trains for the modernization program of London Underground.
I talked earlier about how digital transformation is imperative for all industries. We also helped the bottling company Swire Coca-Cola to advance the digital transformation of their plants and unlock greater productivity. My colleague, Cedrik, will tell you more about this partnership later. Let me talk now about how we are growing our digital business by leveraging our core business and domain know-how. Our remote service for buildings take a digital approach to building maintenance. We can monitor buildings anywhere in the world and identify potential issues, as well as areas for optimization. This offers a compelling value proposition for building owners who need to reduce operating cost and energy consumption, particularly for owners of commercial buildings, retail chains, business parks, university campuses, and data centers. Take the example of Tampere University in Finland.
Our digital services reduced the need for visual inspections by 70%, and almost 60% of issues identified improve energy efficiency. Their maintenance budget has gone down, partly because they need fewer people on the ground. This digital service brings greater benefits to our customers and recurring revenue for our business. Doing it virtually means that we can scale up easily, and it lowers our carbon footprint because our service technicians can do their job remotely. The data we collect gives us new insights into our customer needs so that we can develop new products and services. Today, we are providing this service to almost 4,000 customers, and with more than 100,000 buildings connected to our IT platform, there is further potential to expand. We can also leverage our core businesses and our digital strengths to develop new business models in areas of our business.
Performance as a service in our building service businesses. Here, we guarantee energy performance. A bonus malus is applied to over and under performance. Our joint venture, Calibrant Energy, offers renewable energy solutions as an energy as a service to commercial and industrial customers in the United States who want to reduce their carbon footprint. In our industrial markets, we are enabling machinery customers to create new business models, such as offering their customers machine hours as a service. Siemens Healthineers offers its teamplay digital health platform as a platform as a service to healthcare vendors to help them build and deploy digital solutions faster. Finally, software as a service, where we want to bring innovation closer and much faster to our customers. Over the past years, we have built an unparalleled industrial software portfolio and invested more than EUR 10 billion in software companies.
We have added complementary capabilities to what was already a strong portfolio by acquiring LMS, Mentor Graphics, and Mendix, just to name a few. Today, our customers are looking for greater flexibility and accessibility, as well as new ways of working in a post-COVID world. I am pleased to announce that we will transition part of our industrial software business model to cloud-based software as a service beginning fiscal year 2022. Customers, regardless of size or industry, will benefit from faster innovation, effortless scalability, and lower barrier to entry. For Siemens, it will open up new markets, especially small and medium-sized companies. Ultimately, our transition to SaaS will drive more resilient and more predictable revenue and profit growth. Unlike pure play software competitors, our strong portfolio will enable us to execute SaaS transition while keeping Digital Industries and Siemens AG financial target commitments.
My colleagues, Cedrik, Tony, and Rudolf will provide more details on this later. Overall, we have ambitious growth targets for our digital business. We expect to grow organically at around 10% CAGR over the cycle, starting from EUR 5.3 billion in fiscal year 2020. Due to the SaaS transition, revenue conversion will ramp up more slowly in the first year and will accelerate after fiscal year 2023. What makes us unique in our ability to combine the real and the digital worlds? It is our deep domain knowhow, our leading technologies, and our strong ecosystem. Let's take them one by one. First, our domain knowhow. It is not enough to understand the IT world to develop the digital applications that optimize performance of industrial systems or algorithms that enable predictive services.
You need to understand how the equipment works and the environments they operate in, and you need to understand the challenges of our customers, too. That's why despite fierce competition, we were able to win the Rhine-Ruhr Express rail contract. We know how to build and service trains. We know how to automate manufacturing systems. We know how to design and operate grids and service buildings. Second, technology. Siemens creates technology with purpose. Technology that makes factories more flexible, buildings and grids more efficient, transport more reliable, and healthcare better. Today, we offer a leading technology portfolio of software and automation solutions and a competitive IoT platform. We are number one in factory automation, grid automation, and rail automation. We are number one in industrial software. Technology is a key area where we leverage the power of Siemens.
We focus our R&D efforts on the technology fields that are essential for our customers and our businesses. Technologies like data analytics and AI, digital twin, additive manufacturing, 5G, industrial edge, IoT and cybersecurity, among others. We call them company core technologies because these technologies are relevant for all our businesses. Let's take our digital twin software, which is widely used in industrial markets. We can apply our digital twin technologies to benefit customers in other industries, such as transport, buildings, and grids. For example, we recently implemented a digital twin for our customer, American Electric Power, to help them simplify grid planning. Matthias will tell you more about this later. To develop new innovative technologies, we have more than 40,000 employees in digital jobs across all functions. 12,000 of them are industrial software engineers, and over 1,000 are AI experts.
In 2020, we increased our R&D spend and invested EUR 4.6 billion. Around 50% of this was related to IoT and software. Third, our ecosystem. Siemens has a strong ecosystem. We are continuously expanding it. We collaborate with partners around the world, from developers to startups to big tech companies and research institutes. For our partners, our ecosystem opens the door to large established markets in industry, infrastructure, transport, and healthcare, and this is truly unique. For Siemens, it means that all our businesses can bring innovations faster to the market. Through next47, we leverage the potential of the startup ecosystem to accelerate the development of new technologies and business models. To create even more value for our customers, we are deepening our collaboration with partners. One example is our partnership with SAP to develop a single digital thread to accelerate industrial transformation.
Let's hear from Christian Klein, CEO of SAP.
"Siemens and SAP will provide an end-to-end solution connecting the shop floor in the digital factory to the intelligent business processes in the ERP. I'm very proud that together we can offer a standard and scalable Industry 4.0 solution for our customers. With this end-to-end solution, teams across the business can efficiently work together to design and deliver innovative products productively, profitably, and sustainably." Our partners are important to us because the stronger our ecosystem is, the more everyone benefits. Digitalization and sustainability are growth engines for our business. We are seeing the increasing demand for both digital and automation solutions, and we are anticipating increasing demand in sustainability solutions. Governments around the world have allocated an estimated EUR 11 trillion in stimulus programs. Many of them include measures that will drive demand for digital and climate-friendly technologies in our markets.
Our global footprint will allow us to contribute and benefit from many of these programs. Sustainability has been a priority for Siemens for years. It is embedded in our strategy, our technology development, and our operations. Back in 2015, for example, we were one of the first industrial companies to commit to net zero by 2030. Today, we are expanding our commitments to sustainability by launching our DEGREE framework. It takes a 360-degree approach to environmental, social, and governance issues, and the name DEGREE underlies our contribution to limit global warming. We will now reduce carbon emissions from our supply chain as well as our own operations, and we will invest more into training and education for our employees. That way, our employees can acquire the skills they need to adapt to the changes of the market.
This means we expect a reduced new normal for severance in the range of EUR 100 million-EUR 200 million per annum. My colleague, Judith, who is also our Chief Sustainability Officer, will tell you more about DEGREE later. Siemens is now a focused technology company. We feel very confident that we can achieve comparable annual revenue growth of 5%-7% over this cycle. This is significantly above the projected market dynamic and above the revenue growth ranges we targeted at our Capital Market Day in 2019. Far, I talked a lot about how we want to grow in highly attractive markets. Now, what is our ambition in terms of performance? We are fully committed to translating these opportunities into accelerated value creation for our shareholders and all our stakeholders. We will focus on high-value growth.
We are upgrading profit margin levels for Smart Infrastructure and Mobility, and consequently, we will strive to grow earnings per share consistently by high single-digit % year-over-year. As we have shown over several quarters, our enhanced focus on free cash flow is paying off. We are now adding a cash flow conversion target on Siemens Group level. Free cash flow is the fuel for shareholder return. Siemens has been a very reliable dividend payer for decades. We formalize this now by striving for progressive dividends going forward. We are announcing today our follow-on share buyback program until 2026. I've talked a lot about what targets we want to achieve, and Ralf will give you more details shortly. Let me highlight how we want to further improve performance. One of the guiding principles for our leadership team is accountability. We do what we say.
We focus on execution to constantly improve competitiveness by simplifying our setup and processes, by delivering on previously communicated cost measures for lean and effective governance, and by increasing speed through internal digitalization and better resource efficiency. We will measure our progress, make it more transparent. We will report on how our resilient and recurring business is growing. We will give you more details on below-the-line items and how we improve their impact on the bottom line, and we will develop and execute strategic options for our portfolio companies. In a nutshell, we will rigorously drive profitable growth and deliver on our self-help potential. Of course, compliance is an indispensable requirement in this process. Finally, we will accelerate our clock speed, moving faster, being more dynamic and agile by empowering people, streamlining decision-making, and incentivizing our sales force for high-value growth.
Today, I've talked about how Siemens is uniquely positioned to grow, but what drives us, all 290,000 of our employees, to succeed? Everything we do at Siemens is about creating impact for our customers. We want to anticipate what our customers need almost before they need it. We satisfy their needs by building technologies with purpose, technologies that help our customers solve their challenges to do more with less. I talked about the transformation that is taking place in our markets. We will empower our people to make faster decisions and to be more entrepreneurial. We will always have a growth mindset. We will continue to experiment and adapt. We will continue to grow and learn by investing in education and training. These are our strategic priorities, and they are our roadmap for long-term sustainable success.
Together with the managing board team, I'm proud to lead this company to a new era of sustainable growth and innovation. Our team is well-positioned to execute on our strategy. Ralf has played an instrumental role in steering our company's transformation. He has built Siemens' financial strengths and will ensure a solid foundation for further growth and rigorous value creation. Judith, with more than two decades of experience in driving strategic change, will elevate empowerment, harness the potential of our employees, and accelerate our sustainability approach. Cedrik, with his diverse background, tech experience, and enthusiasm for change, will continue to drive digital transformation at Siemens and for our customers. Matthias, with his in-depth understanding of customer needs, knows where the opportunities are to promote digitalization and sustainability.
Finally, with my own knowledge in technology and business transformation and my experience with markets and challenges of our customers, we, the managing board team, are well-positioned to execute on our strategy. I am confident that we will achieve comparable annual revenue growth of 5% to 7% over the cycle. Here is why. Because we are a focused technology company addressing highly attractive growth markets with our global footprint. Because we can empower our customers to master their digital transformation and sustainability challenges with our technologies. Because we can combine the real and the digital worlds like no other company can. Because we are pursuing a clear focus on profit, cash, value creation, strategic capital allocation, and execution. Finally, because we have the right strategy, the right team, at the right time. With that, over to Ralf, who will tell you about the numbers behind the strategy.
Thank you very much.
Thank you, Roland. It's my pleasure to add what accelerating high-value growth means from my CFO perspective. We have perfectly positioned our company over the past few years for precisely this purpose. Since our last CMD, Siemens has lived up to its commitments and will continue to do so. We improved our competitiveness in all businesses. We executed the Siemens Energy spin-off successfully in record-breaking time. With the transformative Varian acquisition, Siemens Healthineers is executing its upgrading strategy. As our stock performance indicates, the capital market greatly appreciates our transformation. Thanks to joint efforts of the entire management team, we have achieved a step change in our business profile. As a focused technology company, we have de-risked our business profile. Our project and solution businesses now account for a smaller portion of our overall portfolio.
We now have a sharper focus on our highly profitable product, service, and software business. This enhancement is improving our profitability level from a structural perspective. As a result, our gross margin has increased significantly, reaching 35% in fiscal 2020 without Siemens Energy. More than ever, Siemens stands for reliable and consistent execution, thanks in part to a strong share of resilient revenue. Each business is operating in highly attractive end markets that feature tremendous growth potential driven by secular growth trends. We can now build on this platform to further accelerate value creation. Let's not forget, Roland has been driving this strategic transformation for quite some time now, including the work he did in his prior roles as our former Chief Operating Officer and Deputy CEO.
On our path to accelerated value creation, we are highly committed to certain key priorities that I will be focusing on during my presentation. First and foremost, it's all about stringent capital allocation. Thanks to a great team with exceptional expertise and experience, we have a success story to tell in this regard. We have made targeted investments in R&D and M&A, such as Mentor acquisition, and have provided a strong shareholder return. This combination has created substantial value over the past few years. We will continue to build on this story by striking the best possible balance between investment and shareholder returns. Stringent capital allocation will enable us to grow even faster while keeping a sharp eye on profitability. In addition, the entire team is strongly committed to driving cash generation and conversion to even higher levels.
A very valuable success factor for achieving all these goals is our strong investment-grade rating, which gives us access to financing options at highly attractive terms and conditions. I also want to touch upon our management approach on how we want to go about doing this. First, execution continues to be at the center of attention for the entire team. Discipline, dedication, and diligence have been paving the road to reinventing this company. Now, the same qualities will enable us to reach new levels of value creation. Second, enhanced transparency will give you, as investors, more data points to work with. Last but not least, compliance is an indispensable requirement for our sustainable success, and I never tire of stressing this necessity. In our new chapter as a focused technology company, innovation is vital, and we have been driving our technology leadership through stringent capital allocation.
Over the past five years, we have invested EUR 22 billion in R&D. These investments have resulted in an R&D intensity calculated as a percentage of revenue of 8%, well above our main competitors, who have 5% on average. We made these investments in highly attractive growth areas. As Roland has already outlined with numerous examples, we spent half of our R&D expenses on strengthening our digital portfolio. A look at Digital Industries illustrates this point. Here, we invested more than 13% of our fiscal 2020 revenue in R&D. These investments have created a leading digital enterprise offering that is unmatched on the market. We continue to invest into software and IoT. As a focused technology company, our targeted investments in digitalization will drive profitable growth to even higher levels in the future. That's why we have committed ourselves to even more ambitious targets as of fiscal 2022.
Before we discuss the financial framework as a whole, let's have a look at our business aspirations. They form the foundation for our KPIs at the group level. We will start with our targets for comparable annual revenue growth over the complete cycle of three to five years. Digital Industries' leading automation and software portfolio put this business into an ideal position to grow 5%-7%. DI will expand on its huge existing customer base and win customers in new verticals and emerging markets. Smart Infrastructure is expected to grow 4%-6%, with a strong product and solution offering accompanied by resilient service. Mobility has a proven long-term track record of growing faster than the market. This business is expected to accelerate growth to a CAGR of 5%-8%, benefiting from decarbonization and stimulus programs around the globe. Moving on to the margin target ranges.
We are keeping Digital Industries' target margin range stable at 17%-23%. Why? Digital Industries will commence a business model transition for the biggest part of its software portfolio. It will shift from perpetual licenses to subscription with cloud-based software as a service, or SaaS, as people call it. Now is the right time to take this important step because our customers are asking us for SaaS offerings. Cedric, Rudi, and Tony will elaborate on this extremely relevant part of our continuing transformation journey. They will provide details on the required investment as well as on the accounting impact of shifting from upfront to ratable revenue recognition. Let me point out that maintaining our margin range despite these effects is clear proof of our confidence in the strengths of this business.
As you will see, the SaaS transition does not affect our ambitions at the level of Siemens Group either, nor will it harm our capabilities to deliver strong and constant free cash flow. Our profit expectations for Smart Infrastructure and Mobility are becoming more ambitious. They are both lifting their profit margin band by one percentage point each. For Siemens Healthineers, the profit margin band of 17%-21% and the revenue growth rate of greater than 5% reflects Siemens' expectations as a majority shareholder. Our businesses' ambitious growth targets are also reflected in our growth ambition at the global Siemens level. Our targets here clearly take our expectations to a new level. We are committing ourselves to a 5%-7% corridor of comparable revenue growth over the cycle. The previous target was 4%-5%.
Accelerating revenue growth at the company level without sacrificing profitability is, in fact, one of the key enhancements within this framework. What else is new? We will give you more transparency and clarity on what we are striving to achieve over the cycle of three to five years. Vision 2020 Plus has been building the foundation. Of course, we will still honor our commitments from it. Our new chapter as a focused technology company comes with new ambitions for high value growth. Let's have a look at the upper half of the framework, where you will find all targets on the Siemens Group level. To put these targets into perspective, we will look at the period since fiscal 2018. Our new high-value growth ambition will translate into an even larger increase in EPS. We have a very ambitious midterm earnings growth target of high single-digit growth.
This target means that earnings will grow much stronger than revenue. In our strategy review, we identified clear levers to accomplish these ambitious targets. Hence, we are very confident to achieve them in our new setup. There's one important thing to note in this context. Amortization of intangible assets acquired in business combinations is a non-cash item excluded from our EPS KPI. This change is in line with common practice in the market. We want to put cash earnings and our operational performance at the center of attention. After our excellent performance in the first half year, we are well on track to achieve a significant increase in fiscal 2021. This leads me directly to our target for capital efficiency. The 15%-20% corridor remains valid, and we aspire to approach it by fiscal 2023.
Profitable growth, execution on cost measures, and stringent working capital management are the main drivers of our capital efficiency. On this basis, we are confidently sticking to this corridor and anticipate a gradual improvement from current levels. Here, we also want to give you clearer view of our operating performance with regard to ROCE. Therefore, this KPI is adjusted for Varian-related M&A effects. The transformative Varian acquisition is a centerpiece of capital allocation for Siemens Healthineers. To be fully accountable and transparent to our shareholders on the operating performance of Siemens AG, we have decided to report ROCE without those Varian M&A accounting effects, which will be fully transparent to you, of course. As part of our stringent capital allocation, we continue to monitor each M&A transaction closely based on specific criteria. Obviously, return on invested capital has to be higher than our weighted average cost of capital.
We continue to ensure that M&A transactions will have positive EPS effects pre-PPA. As a general rule, these transactions are to be EPS accretive ex PPA in the second year after closing. We will closely track integration costs, synergy, integration milestones, and we will share specific information with you for each and every transaction individually. When it comes to capital structure, I can assure you that we are highly committed to our strong investment-grade rating and to securing our entrepreneurial flexibility. We are raising our target for industrial net debt over EBITDA to a more appropriate 1.5x . This increase mainly reflects a technical adjustment from IFRS 16 lease accounting and has been discussed with our rating agencies. We are highly committed to further deleveraging, and we aspire to approach our target corridor by the end of fiscal 2022.
You will notice that 1 of the main updates in our financial framework is about cash. We are extremely reinforcing our commitment to cash by setting a new cash conversion target to the group level. Changing to a more comprehensive perspective from industrial businesses to group level reflects our new setup as One Focused Company. It also stands for more accountability. As a result, it enables a holistic perspective on income that is converted into cash, and it reflects the commitment of the managing board and the entire senior management team to not allow cash drains below the line. With our new, more focused portfolio converting much better, we are striving for a cash conversion rate greater than 1 minus comparable revenue growth over the cycle at the group level.
On top of that, our focus on cash and transparency manifests itself in our commitment to a cash conversion rate greater than one minus comparable revenue growth for each of our businesses, too. As you can see, the new Siemens AG is highly focused and confident about cash. The entire management team is strongly committed to building on what we've achieved so far in this area and is incentivized to do so. Let's look at the long-term history of Siemens's dividend payments. It's evident that we have continuously increased our dividends since the late '80s. The one and only exception was merely a technical adjustment for the energy spinoff in fiscal 2020. We are clearly dedicated to maintaining a progressive dividend policy, and we are committing to such a policy in our new financial framework.
You may have noticed that the global target range for the overall margin of our industrial businesses is no longer included in this corporate part of the framework. The reason is that margin targets for each and every individual business are more meaningful and provide better transparency. We remain committed to our previously announced target of a 14%-18% corridor on industrial business level. At the business level of our new framework, our simplification and transparency measures continue. On that note, we are switching from adjusted EBITDA to profit to underline the reference to revenue. This also prevents any misunderstandings. In addition to this transition, we will change our profit definition as of fiscal 2022. We are removing the metric financial income from our profit in operating business. It did not have material impact after the energy spend anyway.
Hence, our profit definition reflects a very crisp and clean operational perspective on our business's performance. I have already highlighted our profit expectations for Digital Industries, Smart Infrastructure, Mobility, and Siemens Healthineers. As you can see here, we have adjusted the profit margin band for Siemens Financial Services to 15%-20%. Ultimately, this is a consequence of the spinoff of Siemens Energy. We are deliberately de-risking SFS's business profile to tailor it more closely to our core activities. As I will explain later, SFS is a business enabler for Siemens with a deep domain knowhow and close proximity to the businesses. It generates an impressive return on equity that has been clearly above its market peers for many years. Now, let's move on to an entirely new section of our framework.
A large portion of our business is already recurring, and we will increase transparency and specific resilience performance indicators in each business, beginning with fiscal 2022. DI Software will measure its successful SaaS transition with an industry-typical annual recurring revenue metric, the so-called ARR. The goal is to achieve a CAGR higher than 10% until 2025. Service is a major portion in SI's business and has attractive margins. We aim to grow service revenue 6%-9% per annum. In addition, high-margin service is also becoming more and more important in our long cycle mobility business. One leading indicator here is continuing growth in service backlog. We aim to exceed a CAGR of 8% in this area. Providing you with information on these resilience KPIs will further increase visibility of how our businesses are performing longer term.
All in all, our financial framework provides clear evidence on a very important key point, our commitment to execution and transparency and to driving operational performance and cash generation. These are the standards by which we want to be measured on our way to value creation. Now let's change gears for a moment to address a topic that I often get asked about. Siemens Healthineers' transformative acquisition of Varian is also set to generate clear value. This move is enabling a unique combination of diagnosis and therapy that significantly increases Siemens Healthineers' relevance in the global healthcare market. Closing the transaction immediately enhanced the company's growth profile, and Siemens Healthineers expects the very tangible cost and revenue synergies to exceed EUR 300 million per year in FY 2025. This step impressively demonstrates that our strategy of giving this business greater entrepreneurial independence is working.
Our approach gave Siemens Healthineers the opportunity to finance this major deal efficiently by raising equity through its own access to the capital market. It also benefited, at arm's length of course, from the very favorable debt financing conditions that Siemens AG can obtain. One key aspect for Siemens AG is that the Varian acquisition will be accretive to profitable revenue growth. In the short term, acquisition-related costs will affect our net income. In addition, the capital increase at Siemens Healthineers has reduced Siemens' shareholding to 75%, as you know. Once again, I would like to emphasize that we are committed to remaining a long-term majority shareholder. We are looking forward to attractive, innovation-driven growth, and this growth will be accompanied by sector-leading margins that offer further upside potential. Siemens Healthineers will be realizing this potential as it continues to execute the upgrading phase of its Strategy 2025.
Healthineers is also expanding its portfolio into adjacent growth markets. The Varian and Corindus acquisitions are clear examples here. In addition, its performance is highly resilient thanks to recurring service and reagent revenues, regional diversification, and long-term innovation partnerships with customers. As Roland pointed out, Siemens Healthineers is part of the Siemens core and an important asset on the clear path of further value creation. As I mentioned, we remain committed to our goals targeting fiscal 2023, as presented at the last Capital Market Day, and our competitiveness programs are fully on track. We have been very transparent on the measures and will continue to do so going forward. We are executing these custom productivity measures very diligently. We are also continuously looking for additional potential. As a result, we have been increasing and accelerating our measures to drive margin expansion.
Compared to the figures we announced with our fourth quarter fiscal 2020 results, Smart Infrastructure has lifted its target for fiscal 2023 again by EUR 20 million to EUR 390 million. Global Business Services, or GBS, expects to achieve EUR 95 million by the end of fiscal 2021, a notch above our original target. Furthermore, I am pleased to report that our corporate program is making very solid progress too. EUR 60 million in productivity savings will be achieved ahead of schedule in fiscal 2021 already. By then, we plan to have reached EUR 330 million in total. These cost measures for lean and effective governance are being executed throughout our entire organization. Around half of the savings will be benefiting the businesses directly through improved IT costs, for example. This includes reinvesting some of the funds in areas such as implementing new ways of working.
Very important here, we want to lower the level of extensive restructuring programs and related frictions in the future. We will continuously shape our footprint and optimize processes more proactively and in a timely manner. A key lever will be enhanced investments in digitalization and in training and reskilling accordingly. Judith will explain our approach here in more detail. By adjusting with greater agility, we now expect a new normal for severance for the company in the range of EUR 100 million-EUR 200 million per annum. We also want to boost transparency and give you further insight into what is happening below our industrial businesses or below the line, as we like to say. We are pursuing the long-term goal of reducing and streamlining these items. What exactly is happening below the line? Certainly far more than just governance costs.
Various below-the-line businesses that have full P&L responsibility are key items here. As you know, these businesses deliver solid profits in total. However, an impairment of our Valeo Siemens equity investment impacted profitability strongly in fiscal 2020, and we have been reporting on this very explicitly. I will return to Siemens Financial Services and our portfolio companies in a bit. At this point, I would like to emphasize that we will continue stringent execution of our PoC concept, and no further businesses will be transferred to this unit. As you know, Siemens Real Estate is a steady contributor. Siemens Energy is making solid progress as a successful independent company, as its inclusion in the DAX 30 clearly shows. Our plan has been to lower our equity investment in Siemens Energy within 12-18 months after listing, and we remain fully committed to this plan.
We already disclosed separate figures for the businesses I just mentioned. Let's turn now to our current corporate items, where we want to give you more transparency than we have in the past. There are two P&L businesses that have only minor profit impact to date. Our Global Business Services, which helps its customers integrate, digitalize, and optimize business processes in areas ranging from payments and HR to engineering. Only a small portion of its business, GBS provides third-party services as well. Then Advanta, a growing IoT consulting and software development business in the ramp-up phase. It has around 8,000 employees who are also driving a lot of internal development and digitalization projects for our businesses. Our current corporate items also include very powerful innovation activities with future valuation impact. Roland has already discussed them today. Here, I am referring to the operational cost of next47.
As our global venture capital unit, next47 gives us insights into where to allocate capital in new technologies. We expect the startup activities that we are driving through next47 to have a long-term positive impact as they mature, as we have seen recently with the successful listing of ChargePoint. Another important pillar is our company-wide technology unit. There you will find activities ranging from innovation management and intellectual property to application-oriented project with universities. This is home to substantial and high-caliber R&D activities in company core technologies to provide support across all businesses with breakthrough innovations. Our bright colleagues there are very instrumental in driving medium-term growth that will have a major impact on our future USPs as a leading technology company. Our central technology unit also includes our overarching IoT platform activities.
These activities will play a central role as we continue our company's transformation and enable our customers to benefit from the digital transformation. Overall, the operating expenses for these long-range innovation-related investments amounted to EUR 224 million in fiscal 2020. They will be around EUR 200 million in the years going forward. At our last CMD back in 2019, we talked a lot about our cost efficiency efforts in corporate governance for functions such as finance, human resources, and IT. In the meantime, we have significantly boosted efficiency and implemented measures for achieving a leaner structure, as we saw earlier. On the way forward, we will facilitate our company's ambitious growth plan with a stable level of existing resources. We will also continue compensate for higher wages with achieving continuous productivity improvements. Our long-term commitment in this area is truly very ambitious.
By fiscal 2026 at the latest, we want our corporate governance to be fully financed through the brand fees. Last but important, we also have legacy topics in corporate items. They include miscellaneous topics, in part, going back for decades, such as an asset retirement obligation in Hanau, Germany, or our participation in the Olkiluoto three project in Finland. We will be cleaning up these legacy items for good and will be fully transparent with regard to their impact. There are three other positions below IB worth being mentioned here. Pensions, which need no explanation at this point. Financing, which includes our corporate treasury activities and related interests. The activities included here are a very important part of running Siemens effectively from a financing perspective. This item also contains consolidation and elimination items.
Lastly, an item for PPA recognizing amortization of assets in connection with purchase price allocations from acquisitions across our businesses. Since we already include these PPA aspects in our current reporting very transparently, I won't go into more detail here. As indicated before, let's now return to Siemens Financial Services. Our future reporting on SFS will offer additional details. You will see the debt and equity business split and many more details on its portfolio diversification from an industry and regional perspective. As already disclosed, SFS is seeing a significant, but not yet full, recovery in its profitability in fiscal 2021. Support here is mainly coming from robust performance in its debt business.
I already mentioned that SFS is in the middle of a de-risking process that led to a decrease in total assets for its equity business in the first half of fiscal 2021. SFS is tightly aligned with those industries that the core of the new focused Siemens AG is serving. It is prioritizing capital allocation to this very core. SFS will maintain a high level of diversification and a strong regional footprint in countries that have an investment-grade rating. SFS is more than just a profitable business in itself. It adds value well beyond the mere cost or availability of financing. SFS has a strong long-term track record of successfully supporting our industrial businesses through its profound in-house expertise. Its team has accumulated the necessary domain know-how over decades.
About 1,700 of the more than 2,800 SFS employees are financing specialists, in particular in the areas of origination and underwriting and as well in risk management. As a result, SFS has a far better understanding of our end markets and our businesses than any external provider of financial services could ever have. SFS serves as a highly reliable and professional partner for all of Siemens. In its role as our captive financing arm, SFS has consistently outperformed its competitors since 2017 across all its product lines. Looking ahead, SFS will move beyond its current role in captive financing. It will take on an increasingly important role as a key integrator within the Siemens ecosystem. You have already heard about some examples from Roland, and more will follow in the business presentations. SFS will actively help generate value based on four success factors.
First, SFS has profound domain know-how and is closer to our operations than banks are. Having the ability to get involved at an early stage of the sales process opens doors. It also provides SFS with more insight when it comes to assessing the risk profile of a project or a business model. Second, SFS has a highly experienced team. About half of the people who work there have been at Siemens for more than seven years. This long tenure is significantly higher than the industry average. Third, as I touched on earlier, SFS' strongly diversified portfolio results in lower risk for allocated capital. Mitigating this risk in this way can help Siemens businesses move into new asset classes and innovative business models. Fourth and finally, SFS has strong sustainability DNA and a large sustainability footprint.
About 90% of the SFS portfolio has favorable ESG scores based on Standard & Poor's classification. SFS enables infrastructure projects and technology that help meet our important targets in this area. SFS is fostering accelerated value creation for Siemens with an increased focus on a joint go to market. It can also proactively help to co-develop innovative new digital business models, such as energy as a service, more flexible pay per use, and integrated pay for outcome models. In our view, SFS offers a compelling value proposition for our customers, our businesses, and even for our planet. At our portfolio companies, we are continuing our active portfolio management. The Flender disposal resulted in a pre-tax gain of approximately EUR 900 million after it closed in the second quarter of FY 2021 for a purchase price of EUR 2 billion.
This success has proven the effectiveness of taking a kind of a private equity approach to value creation for these companies. At our remaining fully-owned portfolio companies, we continue to execute our plans for enabling these businesses to reach their full potential. We are focusing on stringent execution in their industry-specific setup as we reduce costs, enhance operational excellence, drive scale effects, and gear the companies towards growth fields. In line with our existing commitment, we are targeting a profit margin above 5% by FY 2022 for these units. Our portfolio companies also include our equity investment in Valeo Siemens eAutomotive. Here, our ongoing transformation program and ramp-up investments will continue. We have been putting all these companies on a strong operational foundation and are now actively pursuing strategic options for their future following the concept of best ownership. As I said at the beginning, it is all about capital allocation.
We can only optimize value if we strike the right balance between targeted investments and shareholder return. To do this, we base all our investment decisions on our strategic imperatives. You have known five of them very well for years, we would like to introduce to you one important new addition, which is sustainability impact. Since Judith will be talking about this topic in depth right after my presentation, I will just say this. In line with our new ESG ambitions, we will also be placing an even sharper focus on ESG when it comes to capital allocation. Sustainability considerations are incorporated into all decision-making and portfolio-shaping processes such as M&A investments, customer project approvals, or supplier evaluations. We are drinking our own champagne by using digitalization and automation to further improve the resource efficiency of our own value chains. Cedric will elaborate on this topic extensively later on.
Looking at the facts, I think we have quite a success story to tell with regard to capital allocation over the last years. Let me point out a few highlights. At the beginning, I stressed the importance of organic investments in R&D to drive technological leadership and superior growth. Through our CapEx allocations, we have been moving our footprint closer to growing end markets and key customers. Over the last few years, we significantly upgraded and strengthened our existing manufacturing base through automation and digitalization. In addition, we targeted investments towards growth markets of the future. For example, in Digital Industries. We have ramped up and expanded our factory in Chengdu, China, which is now generating two-thirds of the output volume of our world-class site in Amberg, Germany. In the field of acquisitions, we have put together a string of pearls.
We have acquired software companies that are not only successful on their own, but jointly complete the Siemens offering in a way that covers the entire life cycle of our customer industries. Together, they put us in a unique position to help our customers combine the real and digital worlds in a way that delivers tangible benefits. Here we are talking about companies like Mentor Graphics and Mendix, and I am also thinking about the recently announced Supplyframe acquisition. Roland already explained its strategic relevance for the entire industrial portfolio of Siemens. As I said earlier, we have a strong focus on attractive and sustainable shareholder returns. Over the last five years, we allocated a total of around EUR 21 billion to our shareholders via dividends and share buybacks.
These returns are reliable even in exceptional times, marked by ongoing uncertainties due to COVID-19 and amid historic changes in the structure of the entire company, such as the spin-off of Siemens Energy. Over the past decade, we achieved a clear growth trend in our dividends with a CAGR of 7% since 2009. The average dividend yield was 3.3% over this period. Very attractive compared to peers. The second pillar of our shareholder return is our share buyback program. As part of our current program, we've already realized EUR 2.4 billion of the overall amount of up to EUR 3 billion. We use a large portion of these shares to meet the ongoing demand from our employee share programs. I'm happy to announce today another long-term share buyback program of up to EUR 3 billion starting in fiscal 2022 and running until 2026.
These two pillars of shareholder return have been combined with excellent share performance since our last CMD in May 2019, underscoring impressively the ongoing re-rating of the Siemens shares. The capital markets have clearly acknowledged our achievements in terms of our consistent operational performance and our new strategic direction. As a result, Siemens has been able to provide an outstanding total shareholder return since our last CMD in May 2019, and we are determined to accelerate value creation even further. Let me conclude with our top priorities for achieving this goal. First, as in the past, we are making targeted investments in line with our strategic imperatives, including sustainability. At the same time, we continue offering our shareholders attractive and reliable returns. Second, we are growing our company profitably. To do this, we are leveraging our powerful innovation capabilities and continuing our transformation.
Third, our entire organization is geared towards strong cash generation. Fourth, we all continue to put a strong focus on execution, transparency, and compliance, which will boost our competitiveness even further. Roland, myself, and the entire management team are fully committed to accelerating value creation at Siemens. Now I am happy to hand over to Judith, our Chief Sustainability and HR Officer, to show you exactly what role sustainability plays on our path to high value growth.
Thank you, Ralf. It is my great pleasure to spend my first Capital Markets Day for Siemens speaking about sustainability, a topic that we are very much committed to and that's very close to my heart. In my role as Chief Sustainability Officer, I am proud to share our approach with you. We're outlining our sustainability story here at Capital Markets Day because that's how seriously we take it. For every part of the world that Siemens has an impact on, our customers, our suppliers, our communities, the governments with which we work, our shareholders, or ourselves. We see sustainability as an integral part of our business. In my presentation, I will focus on three things. Our strong track record in sustainability. Sustainability is embedded in our portfolio, our operations, our governance. In other words, it's in our very DNA. Secondly, our belief that sustainability is great business.
Siemens technology and innovation create opportunities and help our customers achieve their sustainability goals for a better future. Third, the launch of our ambitious sustainability framework, DEGREE. Like all businesses, we want to measure how well we're doing. We are laying out specific targets in our DEGREE framework. Let me start by underlining that Siemens has an enviable track record in ESG for all our stakeholders. We have set ourselves ambitious targets, and we have achieved them. First, I'd like to address our commitment to net zero. Back in 2015, we were one of the first industrial companies to commit to net zero by 2030, and we have already more than halved our CO2 emissions since. We are using our own technology to decarbonize.
In Vienna, Milan, Midrand, South Africa, we have installed microgrids, helping us use more renewables at our own sites, become more flexible, and save energy. Our production sites in Amberg, Germany, and Chengdu, China, have been named World Economic Forum's Lighthouse factories. We have a clear ESG governance framework in place, overseen by our sustainability board that represents businesses, key functions, and regions, and that I chair. We have also integrated ESG components in our long-term incentive scheme. We keep track of our impact. For years now, we have used our business to society approach to quantify our impact, both from business with our customers and our own operations. We're not just telling you a nice story, we're showing you results. In 2019, for instance, we contributed to the creation of EUR 280 billion GDP all around the world.
Last year, our customers saved 150 million tons of CO2 using our products. When it comes to education and training, we invested more than EUR 250 million last year in our people. We used our own knowledge of digital to shift learning largely to the digital world. To date, we have about 100,000 digital learning assets available. Our sustainability performance is also well recognized by external ratings and rankings. We are proud of our results and at the same time, we are inspired to do more. Our expectations are increasing, and so are the expectations of our customers, and we see clear opportunity for Siemens. Let's look at our customer impact in more detail. With our technology and innovation, we are operating in fields that are naturally helping our customers achieve their sustainability goals.
Our experts are involved in customer projects on a daily basis to provide their sustainability expertise and experience. Through digitalization and automation, we are transforming critical areas such as the future of industrial operations, building and grid infrastructure, and mobility. This leads, among other benefits, to greater resource and energy efficiency, circularity, and decarbonization. Siemens is in a unique position to support our customers in all these dimensions. Let me share examples from our customers and the sustainability impact that we're achieving together. First, let's take an example from the automotive industry. Mercedes-Benz and Siemens are expanding their cooperation, advancing digitalization in the fields of engineering and sustainable production methods. This will support Mercedes-Benz in meeting the challenge of building CO2 neutral factories, while also becoming more flexible and responding to changing market demands and integrating information and operational technology in a new work environment.
Simplified software developments with local platforms such as our Mendix will enable the re and upskilling of white and blue-collar workers with future-proof skills and competencies. Overall, the Mercedes-Benz Digital Factory Campus in Berlin is intended to serve as a blueprint for all Mercedes-Benz plants, and Cedric, of course, will share more on this. Our microgrid systems are helping many customers around the world to decarbonize and become more energy efficient. For instance, in the Azores archipelago, our autonomous battery-based energy storage system and microgrids are enabling the share of renewables increase to 60%, while reducing CO2 emissions by more than 3,500 tons. This is in addition to increasing grid stability and resilience. Matthias will talk more about the additional lever Smart Infrastructure can offer. Another example are our battery-powered commuter trains from Siemens Mobility.
The Mireo is the new eco-friendly and economical regional and commuter train from Siemens Mobility, which recently won the German Sustainability Award for Design. With the Mireo Plus battery trains, we provide locally emission-free passenger transport, for example, for the State Office for Railway Vehicles in Baden-Württemberg in Germany, operating with or without overhead power lines. We can achieve 25% energy savings compared to previous models throughout operations. On top of this, we are able to recycle 95% of the product at the end of the life cycle. Michael will share further details later about our new trains with alternative propulsion technologies. These examples underscore our exceptional position as a technology company. With our innovation and expertise, we offer solutions to our customers all around the world to overcome their sustainability challenges. We will continue to seize the business opportunity.
We are proud of what we have achieved so far, and as we have just outlined, we want to achieve more. To do this, we must address ESG internally and externally, making it more tangible, memorable, and easy to operationalize. This is why we are launching the DEGREE framework today. I am very proud to announce this comprehensive framework that will guide us in the way we do business all around the world with specific targets in each of the areas we want to drive. It offers, to my mind, a very high level of ambition on where we want to go. DEGREE highlights the need to limit global warming to 1.5 degrees Celsius or below, the toughest challenge we are facing collectively on this planet.
As you can see, each letter in DEGREE represents an area where we are committed to advancing sustainability and give ourselves clear targets. D for Decarbonization, E for Ethics, G for Governance, R for Resource Efficiency, another E for Equity, and finally, an E for Employability. Let's look at each of these areas, starting with Decarbonization. We have spoken a lot in the last few years about decarbonizing our own footprint, and we have gone a big step further this year by signing up to the Science-Based Targets initiative. We will reduce emissions along the entire value chain to stay within the one and a half degree threshold.
This means that we are not only aiming to be carbon neutral in our own operations by 2030, but that we are extending our commitment to all emissions connected to us, from our supply chain through to the use phase of our portfolio by our customers. We can achieve the biggest impact for our customers and their operations, and we are proud to offer solutions for decarbonization such as energy performance contracting in both buildings and manufacturing sites. Now let me talk about our approach to ethics. We are committed to fostering a culture of trust. Our values and ethical standards for doing business are deeply anchored in our business conduct guidelines, on which we train all our people globally at least every three years. Compliance remains a top management priority for Siemens. Now, trust needs to extend to the digital world.
We are recognized as the industry leader in cybersecurity and co-founded the Charter of Trust with global cross-industry partners. The aim is to protect data and drive cybersecurity in a trusted digital world. We are also committed to the United Nations Global Compact and their guiding principles on business and human rights. We have hardwired this further in our governance model. There is very clear evidence that strong governance and leadership within a company closely correlates with better, more sustainable business and sustainability performance. Strong governance reduces business risks and secures our license to operate globally and locally. Good governance is built into our state-of-the-art management systems, and we also extend that to our supplier base. We work with around 65,000 suppliers, and a commitment to our supplier code of conduct is the basis for an ESG-secured supply chain.
We have also included ESG criteria in our long-term incentives program, both for the board and our senior management. The area of resource efficiency addresses the fact that we want to successfully advance recycling and circularity. With our eco-efficiency program, we focus on the input factors of sustainability and have set a standard in designing eco-compatible products. Our latest internal innovation is the Green Digital Twin that offers sustainable options for every component part in the design phase of a product. By 2030, 100% of all relevant product families will be covered by a robust eco design approach. We will focus on decoupling of natural resources through increased purchase of secondary materials for metals and resins. Lastly, we are reducing our waste to landfill ultimately to zero by 2030. Next, let me talk about equity, a word that we tend to attribute to the financial world.
What we want to talk about here is equitable treatment and respect that form the core of our value system. We foster diversity, inclusion, and community development to provide a sense of belonging for all our people. Here, a number of targets again underpin our positioning as an employer of choice and promote a culture of diversity and equal opportunity. For instance, 30% of our top management will be female by 2025. Through our employee share plans, our people widely participate in Siemens success also as shareholders. When it comes to how we work, we were one of the first big industry players to commit to two to three-day mobile working policies for 140,000 of our people. Last but absolutely not least, I want to speak about employability. In a world that is permanently changing, it is absolutely crucial that we all remain resilient and relevant.
This is critical for us as a business and as individuals, if we want to be successful over a long and fulfilling life and career. When I speak to our people, I want them to know that we care about them and are vested in their physical and mental wellbeing, as well as their skillset. Digitalization disrupts how we work and the type of work we do. That is why we invest in up and reskilling on a continuous basis. We are now increasingly supporting customers on their digitalization journey, also with regards to up and reskilling of their people. We have hardwired our ambitions again in targets by which we want to be measured and measure ourselves. Digital learning hours for our people, access to mental health and assistance programs, and our people's safety, which is immensely important for us.
As you can see from this overview I've given today, with our DEGREE framework, we have now defined concrete initiatives and set clear, very ambitious targets for all core topics that we will drive together with our customers. Let me summarize. For us at Siemens, advancing sustainability is not an option. It's a business imperative. We are building on an enviable track record and experience, which offers huge opportunity for our customers, for society, and for us. Technology with purpose is embedded in our business strategy and drives our businesses. With the DEGREE framework, which we proudly launched today, we are accelerating our sustainability efforts. Let me leave you with this final thought. Creating value for our customers and creating a better tomorrow for the societies they serve are not mutually exclusive.
What's good for our business and what's good for people and our planet go hand in hand, and that is at the heart of what we do. Thank you for your time today, and now it is my pleasure to hand back to Eva for the Q&A session.
Thank you, Judith, Roland, and Ralf, for this exciting overview. We're now ready to open our first Q&A session. For our active participants, please make sure that you're familiar with the instructions in the email. In particular, please make sure that you use the blue talk request button or star five when dialing in via phone. Please limit yourself to two questions only, as we already have quite a few participants waiting in line, and we plan to finish on time at around 11:10 A.M.
We will start now with our Q&A. The first question goes to Andreas Willi from JP Morgan. Andreas, please go ahead. Your line is open.
Good morning, Roland, Judith, Ralf, and Eva. My first question is on your comments this morning on the guidance. Maybe you could quantify the net impact we should keep in mind for the Varian acquisition on H2 between the operations, PPA, and transaction costs. If you could elaborate a bit what drives the underlying upgrade in terms of regions, markets, or businesses. The second question is around control and risk management. Obviously, Siemens is seeing strong growth. Management wants the organization to focus and accelerate these growth opportunities. How are you ensuring that the discipline on cost and risk is adequate and businesses don't lose sight of sudden market changes or get called out in terms of discipline? What tools, KPIs, or incentives are in place to ensure that? Thank you very much.
Thank you, Andreas, and good morning. Well, in the third quarter, we see really a continuous strong growth across our businesses. In some areas, they're even ahead of our assumptions, which gives us the confidence for the remainder of the fiscal year. On the positive side, we definitely see a benefit from the continuous very strong Chinese market. On the other side, I'm very mindful about the strain supply and is it the rising commodity prices or is it semiconductors? So far, our team does an excellent job. We believe that we can secure supplies, and we will be able to deliver. All in all, this led us to the point that we remain with our net income guidance from EUR 5.7 billion-EUR 6.2 billion. However, we include now the burden from the Varian acquisition into that.
The next thing is that on August 5th, on our regular Q3 disclosure, we will share more information with you. Ralf has, I think, something to add.
Thanks, Roland, and thank you, Andreas. Welcome also from my side. Andreas, you probably remember with the second quarter's disclosure, I have been indicating that we do expect from the Varian impact something between EUR 300 million-EUR 500 million. This is still valid. It's of course up to Siemens Healthineers to give more color to the content of that, but this is the underlying assumption for our guidance, still EUR 300 million-EUR 500 million. Let me also give a bit more color on the momentum that Roland has been describing. Clearly, China is still growing, and we are participating there very fruitfully with all the investments we made historically. This is bearing fruit now. We very much appreciating that momentum. However, it's not only China.
We see a broad-based recovery in our main and most relevant economies, including the central European countries, but also the U.S., as a typical process industry country, is picking up. From a vertical perspective, it's the typical suspects, if I may put it that way. We benefit with a strong showing in automotive and in machine building, but also in food and beverage and also in other process industries around chemistry. One of the big strongholds of the past, of the prior quarters, EDA Semiconductor, is still holding on strong. However, it's not only the short cycle business of DI. We also have been creating quite some momentum in our SI product business, electrical products, and the scalability, margin conversion, and cash conversion is of the essence. We see them moving strong. Above the line, broad-based industrial business momentum that is kept.
As Roland has been pointing out, we have a great team managing our supply chain. There were no material hiccups so far. Still a lot of miles to go until the fiscal year will be completed, but we have an outstanding team there and all the ingredients to master the challenges on the way to get there. A last quick remark. Below the line, our POC activities are executing on their full potential plans as planned, and we are committed to reach the intended margin range of 5% plus in next fiscal year and are on a good trajectory to get there. Siemens Financial Services is doing quite well and is executing along the lines we have been indicating before with a relatively low default rate when it comes to the liabilities out there.
We do see a broad-based momentum also based on the fact that our cost out programs are executed consistently, as you heard me presenting before. All that, in a nutshell, has been taking us to that point that Roland has been describing. Let me change to the other question you have been raising, and we have a lot of respect for that. Growth needs to be managed, not only in terms of risk, but also in terms of cost consciousness, rigor, and discipline, and we have been learning a lot from the mistakes of the past, our own mistakes, but also have been looking into others. Cost discipline is across the board.
We have been dedicating a management board workshop on the matter, literally each and every line item below the line and above the line is getting the attention it deserves, means that we are committed to execute our cost out plans. Of course, we are also looking into the discretionary spending, even though we are sitting on quite a favorable cost positioning at the moment, we are also mindfully of managing that the way forward. Of course, there will be traveling as soon as COVID policies allows, we will not bounce back to the former T&E levels. We also have a sharp eye when it comes to internal controls and new business models. We benefit also from the proximity to our customers.
We anticipate their next moves into the digital models they are creating to better cater for their customer needs. We accompany them from the very beginning, and it's also quite helpful, to be honest, that with our combined offering of Siemens Financial Services and our industrial businesses, we at a very early stage can jointly assess the risk of those new business model at customers. We have a very broad-based and comprehensive scheme in place that also goes into the incentive schemes of the individuals as far as their focusing and their activities on those critical matters. This includes channel management as well as just the regular course of business, which means economic equation. Whenever there's cost inflation or factor cost increase, that needs to be compensated by productivity this year, next year, and the years to come.
We feel well set for those challenges, but we are very respectfully looking at them in each and every of our businesses.
Thank you very much.
Thank you.
Thank you, Andreas. The next question comes from James Moore from Redburn. James, please go ahead. Your line is open now.
Yes, good morning, everyone. Hi, thanks very much for taking my questions and all of the detail today. I see you have left the DI margin target unchanged despite the higher digital investment needed for the SaaS transition. Could you quantify the digital investments needed for DI, how long we should model that? Am I correct to say that underlying margins in DI, effectively, you expect to rise before those cost items? What's really driving that? Is it software or automation or both?
Thank you, James. You can well imagine that this was one of the centerpieces of our own internal discussions before we have been presenting this to you today. Therefore, let me quickly make a very important remark in the very beginning. You do know that we have a combined offering of industrial software and of automation business, which are tightly linked to each other. This proximity to our customers allows us to really very well listen to them and adjust our offering and the pace of the introduction of our SaaS regime to their individual needs. This is a very important point. I'll come to that back in a second. This means in pity, what we do is we continue investing in the SaaS transition.
You may remember that already back in 2018, we started to explicitly report to you quarter after quarter how much we invest in that what we call cloud investment, including SaaS transition, MindSphere integration of Mentor and the like. That was on throughout those three years, those past three years, between 100-200 basis points. Last fiscal year, it was 110 basis points impact on the DI margin. We will continue with that pretty much on the same levels as a cloud investment and SaaS investment in the years to come. The grand total over the period of five-year for SaaS transition itself, focusing on that for infrastructure, preparing ourselves to be ready for the customer needs, implement and roll out will be something like EUR 100 million on average. Grand total, EUR 500 million for five years, if you will.
On top of that, this is now important, there's a revenue recognition piece. Moving from upfront revenue recognition to ratable means that there will be an impact on margin, and that we indicated will be up to 200 basis points at peak. We expect that to happen hopefully as early as possible, means fiscal 2022. Referring back to my introductory remarks, this is up to the customers. We will follow their wish, and we will not try to push them into something. Therefore, we are very mindfully looking into the different market segments. Roland has been pointing out, Cedric and Rudi will go into more details later on. The pace is difficult to anticipate. From our point of view, we appreciate the best and fastest moves that our customers wish, and we stand ready to do that.
That will take us to a maximum peak impact of up to 200 basis points from revenue recognition. Good news, however, is twofold. First of all, only half of that impact will be impacting cash. That's definitely a good news, and we looked into it very carefully. Secondly, after the transition, we will continue to have a higher pace of growth plus a better profitability and a better structure and resilience in the business. It's an upfront investment, which we will be able to compensate to a fairly large extent by the operations surrounding it. We will not push customers into our timeframe, but we'll listen to them carefully, and the transitioning will be as smooth as possible.
We have been thinking through all the different scenarios, and we feel quite comfortable with coming back to the prior levels of profitability for DI after three to four years. I think that's important.
Cash will not be the essence. There will be revenue recognition artifacts, if you will, in the beginning, that take us to that maximum dip of 200 basis points. The investments in infrastructure will be on the same levels as in prior years, so no surprise, and we will transparently report to you quarter-over-quarter. Good news also, we do see quite a lot of momentum, as we said, answering Andreas' question in the market at the moment. New orders are coming in quite nicely. We have more visibility also than we used to have in that business, and therefore we are quite confidently looking into the rest of fiscal 2021, and 2022 seems to be also in a framework that allows us transitioning smoothly to SaaS and cloud solutions without having major material impact on the company.
Very helpful. Thank you.
You're more than welcome, James.
The next question comes from Martin Wilkie from Citi. Martin, please go ahead. Your line is open.
Thank you. Good morning. It's Martin from Citi. Two questions about how the company will be run in terms of incentivizing management. I mean, firstly on the divisions, you no longer have the industrial profit target, more the divisions. Does that suggest that it's more decentralized, that their bonuses and their KPIs are going to be much more on their own divisions? Related to that, coming onto ESG, obviously some very ambitious targets across the company there, how does that filter through the organization? How do you ensure the divisions contribute to these targets as well? Thank you.
Let me start, and then I will hand over to Judith to talk a little bit more about our ESG program. There's no change. We have a very clear focus of our businesses on their expectations. Is it on the top line? We are guiding also for higher growth on the top line, but also on the bottom line. Everything what you see was also, as Ralf said before, coming up from a bottom-up strategy review, where the businesses came with their proposals where to go, and they clearly understood that we want to go for high-value growth. Means capital goes in our company where we see improving margin, where we see a value increase, but also where we can really go for number 1 positions in our markets and strengthening it. Wherever we have a gap, to close it as fast as possible.
That's the mentality, and we see that it was clearly taken by our management teams and they came back with a great proposal, which gives us the confidence to go up with our financial framework as described. On ESG, I just can say that we see more and more this is really embedded in what we do in our strategy, in our business, but also in our research and development. I think Judith is a very good person to talk about it.
Good morning, Martin Wilkie. Very happy to meet you and to answer your question. Sustainability for us is an enterprise-wide effort, and as Roland Busch just said, we derive it from our purpose. It's anchored in portfolio operations and governance, and ever since 2019, we've also anchored it in the compensation of our managers through the long-term incentive schemes. 20% are ESG related and reflect the stakeholders that we want to represent there. Two of them are actually things that also derive from our DEGREE framework, the learning hours as a proxy for employability, and also our efforts in own operations to decarbonize. Those two DEGREE KPIs are already hardwired into our long-term incentive schemes. Of course, accountability needs to sit across the organization where business is accounted for.
Therefore, our CEOs in the businesses and in the countries also are heavily responsible for having a look at how sustainability aspects actually develop through the value chain that they are responsible for. They actually have a cascaded version of the DEGREE KPIs that we have just put forward. This is monitored at all levels of the organization, and at the very top, we've installed a sustainability board that consists of business, regions, and functions that I chair, that also obviously has a look at how we're making progress against the targets that we're setting ourselves here, and the ambitions that we're setting ourselves and govern activities and strategies at a corporate level, at an enterprise level for Siemens.
Great. Thank you.
Thank you, Martin. The next question comes from Ben Uglow from Morgan Stanley. Ben, please go ahead.
Hello. Good morning, everyone. I hope that all are well. I had two questions, please. One really was for Roland on your big picture vision for M&A and in terms of the M&A strategy. You mentioned transformational versus bolt-on, and in particular on software. If we look at what you guys have done, you've done a series of very successful bolt-on acquisitions. If I think about UGS or Mentor, Mendix, et cetera, over the years, and it's become a really big, viable business. Can you get to where you want to go over the next few years just by doing more bolt-ons in software? Do you have to go down sooner or later a transformational route? Can you just give us your big picture thinking? Can we get to where we need to be in Digital Industries Software just by doing more bolt-ons? That's question number 1.
Question number two, I guess maybe it's for Ralf. I do remember you guys not long ago saying POC portfolio companies would be gone. It would be gone in a relatively short period of time. Can you just update us on how long it's going to take to divest the businesses in POC, please?
Thanks, Ben. You mentioned the successful journey which we made with bolt-on acquisition on software. There's no reason why we should not continue doing that. Bolt-on acquisitions is really something where we believe we have a very strong track record. We can go forward, particularly in the software space, but also in the spaces which are adjacent, where we're describing that how we are adding new markets. Supplyframe, opening the market for cloud-based marketplaces is one example, where I think it's a very smart bolt-on acquisition, yet on an adjacent area, which is very interesting. Overall, we made also very clear that we have clear guidelines how we deal with M&A. It's three elements. Number 1, we have our strategic imperatives.
Very quickly, growth market, good profit pools, should fit to Siemens, synergies, innovative, disruptive preferably, and we added one more element, which is it should support our sustainability program and target as well. Number two, ROCE above WACC, number three, a very clear earnings per share PPA within two years. That's the point. Therefore, I do believe that's the right thing to do. If it comes to the question whether a transformative acquisition would bring us there, I don't know. We do have the firepower to do that, but we prefer bolt-on acquisitions, which are really giving us a very strong record. We can also put the eggs in different baskets. Think about our industrial software, about our vertical software, which we have in Smart Infrastructure and Mobility. We are looking definitely into that. I hope this answers your question.
Thank you.
Ben, POC, the portfolio companies are close to my heart, not only because I'm personally responsible for that part of the portfolio within the managing board, but also because we have been coming a long way to identify what is focus and core to our business in the future and what isn't. If it isn't, and if it is part of POC, that does not mean it's not a good business. It just takes a different management and leadership approach, and that's what we have been implementing with what we call PE-like style of leadership and style of management. I think we have been demonstrating quite well with the Flender case, if I may put it that way, that we can find a better owner than Siemens, and at the same time strengthen the performance on the way to get there as we did for Flender.
I think that case is speaking for itself. Therefore, I won't repeat that. You are very well acquainted with the outcome. That has been encouraging us to consequently pursue that path of managing those companies in a way that they do not stand in the center of the core activities but are tailored to the individual needs of the individual markets and therefore can sharpen their profile. Is it in the go-to-market or is it in profitability and cost efficiency? That's what they are out for. We have been creating a so-called full potential plan for each and every of them, and they are very stringently executing along the lines as I mentioned before already. Nevertheless, we are not sitting on a burning platform.
We have great businesses there, so we are not in a hurry, but we will consistently check who is the best owner for a business and what can we accomplish if we do the right thing at the right time. Along the timelines, I can't be more precise than that, but you saw and see from the activities that we keep them separate, tailor them to the market needs, and I can only ask you to stay tuned on the matter. It will be interesting on the way forward. There's one element in that portfolio that is different, and that is our Valeo Siemens eAutomotive business, a joint venture with Valeo. They are in a heavy investment mode. It's a very interesting and very highly attractive future market in eMobility. We are in investment mode, and therefore, this has a different profile, but we talked about that.
When it comes to the fully consolidated businesses in PoC, we are fully on track, and we will find the best way forward for each and every of those businesses there. On the way to get there, we are still committed to the 5% profitability being accomplished in fiscal 2022.
Understood. Thank you. Thank you very much. I'll pass it on.
Thank you. We're nearly out of time. Simon Toennessen, you're next in line. Simon, if you could please limit yourself to one question, given the time constraints that we have today, unfortunately.
Sounds good, Eva. Thank you very much. Good morning, everybody. Could you just describe the growth pattern in DI a bit better over the next two to three years? You had this chart where you showed the 10% CAGR. Obviously because of SaaS, quite a slower ramp up in the early years. When we're thinking about the 5%-7% growth target for DI, is it fair to assume that we would rather be towards the lower end or maybe even slightly below the lower end for the first two years given the SaaS transition? Do you think you're going to be within the range despite SaaS? Maybe just in connection to that, do you have a target for how much ARR you want to have, let's say by fiscal 2025?
I would presume a lot of your customers still prefer licenses even further down the road. Thank you.
Hi, Simon. I make that rather short because we have another session where we have Cedric and Rudy ready for your question to answer just on a high level. What we want to do is we want to grow our ARR in the CAGR of more than 10% until 2025. That's what DI is going to tell you. The growth pattern of DI is take it regional. I think they have a very strong foothold in China. They are very strong in Europe, they also have their strengths in the U.S. It's really a very balanced regional approach, again, very strong established in China, also on the vertical markets. We are establishing ourselves stronger in food and beverage. You will hear more about pharmaceutical.
You see about the new markets which are growing with its battery automation, any kind of market which is also pulled by either digitalization, automation, or sustainability. Therefore, I do believe that we have a very intact vertical market combination too. I do believe that Cedric and Rudy will be much better in explaining it to you.
Great. Thank you very much. Thank you all for your good questions. We now conclude the first session for a short break of 15 minutes, and then we move into Digital Industries, and I believe that a lot of the questions that you seem to have also about SaaS transition and software will be answered during that session, including Tony Hemmelgarn, the CEO of DI Software. You have the opportunity to ask further questions right after that session. With that, let's enjoy your break. Welcome back to our first business session on Digital Industries. CEO Cedrik Neike, CFO Rudolf Basson, and our DI Software CEO Tony Hemmelgarn, will walk you through our leading digital enterprise business, the strategy, and the ambitious targets. Please also note that the handouts have been published on the investor relations website. With that, over to Cedrik.
Siemens is our global technology partner who never sleeps.
In Siemens, we have secured a strong partner with outstanding digitalization and industry expertise.
Siemens is the only company providing us digital consultings, digital solutions, and automation equipment.
Within this partnership, Volkswagen benefits from Siemens' strengths.
Together, we will be driving forward the development of sustainable future technologies from our Mercedes-Benz Digital Factory Campus, Berlin, into the whole world.
Vingroup has greatly benefited from the partnership with Siemens.
They enabled us to produce novel messenger RNA cancer therapeutics as well as our COVID-19 vaccine.
Tecan is a small to medium enterprise specializing in electrical engineering solutions with our system Craft, which relies on Siemens automation and digitalization.
Building connectivity solutions in our own factories, but also using key elements of Siemens MindSphere as part of the Industrial Cloud platform and marketplace.
VinFast, one of our group company, is positioned to be the world's leading company in smart and electric vehicles, partly thanks to the partnership with Siemens.
We worked with Wolf of the Willows to reduce their ferment time down from 25 days to 18 days and actually grow their business through the COVID lockdowns.
I'm very excited about this partnership with you, with Siemens. Hi, I'm Cedrik Neike, CEO of Digital Industries. You just heard about the potential in digitalization and automation from Roland. He told you 60% of all manufacturing tasks can be automated, which means there's even more potential in digitalization in all industries. Let me give you an example. Think of your car. The industry that manufactured this car is already highly automated and digitalized. Think of the vaccine that all of us have been waiting for. This industry has just accelerated its digitalization and automation during COVID. It had to. Think of all the things which are being produced. All of the things will need a solution to take their products apart and feed them back into the circular economy. This is only possible through automation and digitalization.
The secret is, it won't be enough to deploy a single solution for single steps. Our customers, what they want is processes to be woven together in one integrated value chain. Siemens Digital Industries is solving exactly this problem. We're able to solve it like no one else. That's the reason I'm so excited to show you on how incredibly valuable Digital Industries is for society, for our customers, for Siemens, and of course, for you, our shareholders. Why is that? Because we are in every part of the product and production lifecycles. From design and simulation to controllers, to edge devices, to the cloud, we have all the pieces of the puzzle, and we're the only one who can bring them all together. Let me give you an example. Let's go back to your car.
You use Siemens software to design it, to simulate it, to plan its production. You use Siemens technology to actually manufacture it. When you drive the car, that data goes back to the designers, telling him or her on how to make the next car even better. That is what we mean by combining the real and the digital worlds in an infinite data loop. We do this for all sort of products, your sneakers, smartphones, perhaps even your surfboard. Everything you can think of. How do we do this? We digitally represent everything. Products, factories, plants, even processes from the real world. We call this the most comprehensive digital twin. We also enable our customers to analyze their data in the real world, either on the edge devices directly at the machine or in the cloud. We call this sensor to edge to cloud.
It's also a unique concept. We weave all of those processes together in one single digital thread. This is only possible if you understand both worlds like we do, with our deep domain knowhow. At the same time, we open it up to a vast ecosystem of customers and partners. I shared with you why we're different. It's proof on how we are helping our customers do important innovative work. It's also why I'm proud. I'm proud of my team and our results. It's why we're number one. We're number one in automation, you know this. We're number one in industrial software, and you'll hear much more from Tony about it in a few minutes. We're also number one in areas you might not know, such as industrial communication, the core technologies with 5G being very important. We won't stop here. We have a plan for more growth.
You've seen this in the first half of this fiscal year. We want to accelerate it even further. I will elaborate more details of this later. First, let me introduce you to Siemens Digital Industries a bit more closely. We have nearly 72,000 passionate employees globally. In fiscal year 2020, our orders were €16 billion, we generated revenues of €15 billion, and our profit margin was 16.6%. If you break it down, 65% of this came from automation, 28% came from software, and 7% from services. Our goal is to stay as close as possible to our customers. We have balanced our footprint that includes global headquarter location in all three major regions. Our global headquarter for software is in the U.S. under Tony. Our global headquarter for standard motors is in China, and our global headquarters in automation is in Germany.
With global headquarters in all three major regions, we're able to make business decisions much closer to our customers in their markets. These markets, they're huge, with huge potentials. They will grow at around 6% annually. COVID has shown us one thing. It has shown us that companies who already use Industry 4.0 solutions have grown. They've reacted much faster. The ones who didn't, they suffered. Industrial companies have understood that they need to automize and digitalize and we have all the capabilities to turn this potential into business for them and therefore also for us. You can see this in the numbers. Today, only 11% of companies use digital twins, but this share will grow in 3 years to up to 34%, 3 times as much. This just gives you a view on how big this market opportunity is for us.
Companies want our solution because they know they have to be more flexible, more productive. They have to be faster. As Judith said, they want to be more sustainable. They want to ensure higher quality, and they want to offer new business models. Let me translate this to what it actually means for our customers. Let's go to Vietnam. We worked with a leading company there, which is called Vingroup. They do everything from smartphones to cars. We worked with them to build an automated factory from scratch. You know in how much time? 21 months. Unheard of in the industry. Why did they do this with us? We had this comprehensive twin digital strategy. The interesting part was, when COVID struck, they used this knowhow from the digital twin to pivot their smartphone production also from us to ventilators.
You just know in how complicated it was for a lot of their competitors. You know in which time they did this? three weeks. Vingroup can now manufacture 55,000 ventilators a month. That's what we mean when we talk about going much faster, because Vingroup could turn on a dime when things go into a different direction. That's what digitalization and automation does for our customers. You've seen what we can do with Vingroup. With our help, they became hyper-flexible and hyper-competitive. By combining the real and the digital worlds with our end-to-end capabilities and our domain knowhow, that's how they did it. We're actually making this differentiation replicable to all customers, to all industries. This works as well for brownfields, but also for greenfields. How do I know this?
Since I started, I talked to more than 100 customers, they all asked me the same thing, "Who can tell me on how these technology actually work and if they really make a difference?" My answer was simple. We can. Why? Because we drink our own champagne. We use our own technologies in our 140 Siemens factories. Some of those factories of Siemens are the most advanced ones in the world. The World Economic Forum has selected our factories in Amberg and Chengdu as lighthouse factories. You know what? We're building more of them. For example, in Nanjing, we're using our digital twin concept from the onset to build this factory. It will be the most advanced digital factory for motion control products in the world. It will have 20% more productivity, 30% more volume flexibility, and it will save 2,900 tons of CO2 per year.
Why does this differentiate us from our competitors? Most of them are either software players or hardware players. We have the two, software and hardware capabilities, and that makes a big difference. When we're finally done with COVID, come and visit our factories or take a virtual tour. That's why companies like Mercedes-Benz, they want to work with us. Roland and Judith both have mentioned this. Why? Mercedes wants a partner that can help them holistically on their transformation journey. How do we do this? one, they want to make their production flexible and sustainable as they're moving from combustion engines to electrical ones. two, they want to make their factories building more efficient and carbon neutral because they have a pressing need to decarbonize. This is where our colleagues from Smart Infrastructure, that's where Matthias comes into play.
three, they have to and they want to retrain their workforce to make them more employable for the future. We're supporting them with Mendix. On top of that, Advanta is helping us orchestrate all of this. This is a great example on how all Siemens businesses together create more value by bringing all of the Siemens offerings together. We're actually starting with one of the oldest brownfield factories, and together we want to make it a blueprint for the about 30 Mercedes factories worldwide. If I come back to the DEGREE framework Judith talked about, we're working here on decarbonization, resource efficiency, and employability all in one. We can do this not only for established companies or carbon effectors, we can also do this for young companies. I talked about the vaccines early on. Let's look at BioNTech.
It's a very different industry, digitalization works here as well. We actually have been working with them for quite a while, still when they were very small and in cancer research. When COVID struck, they were faster than anyone else with a new mRNA vaccine to the market, and they were capable of scaling up their production with our help. We were going from milligrams to vaccinating the world in record time. Why? Because they used our technology, and they are now working with us to replicate those vaccine factories around the world. You see, we're helping every type of company grow, reinvent itself, and all of them need automation and digitalization to do so. No one else is actually better positioned than us to deliver this sustainable growth. We're actually obsessed with making this work.
Let me actually share with you on how we do it. First, we are very close to our customers. This helps us continuously improve our go-to-market. We have access to more than 250,000 customers worldwide, small ones, large ones, across several verticals, in China, in the U.S., everywhere. This actually allows us to learn and understand what they really need. Even during the pandemic times, we stayed very close to our customers. In the past year alone, we reached more than 100,000 customers through our virtual events. Many of you have actually visited our Hannover Messe, if you haven't, please watch the videos. They're very informative. We are so close to the customers, we know which technology they need to accelerate their digital transformation. That's my second point. We at DI, at Siemens, we are the technological leader. Let me give you an example.
In the last fiscal year alone, Digital Industries has invested more than EUR 2 billion into R&D. This is more than 13% of our revenue, which we invested into R&D to drive digitalization and automation. It's twice as high as any of our competitors or their partnerships which exist in the field at the moment. You know the great news? The great news is all of Siemens can benefit from this innovation in the core technologies such as IoT, industrial edge, cloud, 5G, artificial intelligence, or even additive manufacturing. On top of that, we at DI, we profit from the groundbreaking innovations and patents of the Siemens core technologies. Third, we can't do this on our own. Our idea is to build an open cloud-based ecosystem and platforms for our customers. We've done this traditionally with our TIA platform with more than 100,000 users for an automation engineering environment.
With our Mendix acquisition, our low-code platform, it makes it easier for engineers and producers to code, so they don't have to become developers to get their benefits from digitalization. Recently, Mendix has been named the leader in low-code development platforms by Forrester. This is a fast-growing environment with already 200,000 developers using this tool. On top of this, we're extending this now into the supply chain. We're adding Supplyframe, a digital marketplace company focused on the electronic supply chain. They're reaching up to 10 million users per month. This is a huge opportunity to let the global industry community digitalize in a cloud-centric world on their terms. Now, we are close to our customers. We continuously invest in innovation for them. We build ecosystem to help them scale and to create value. What's also extremely important, sometimes we don't have everything.
When we need to enhance our DNA for this, we strengthen it through acquisitions. This can really be seen in the software area, where we spent more than €10 billion in the past decade. With our acquisition of Mendix and Supplyframe, we're driving this even further. We want to constantly find new ways of creating values for our customers, to grow the digital, and to stay ahead of competition. There's no one else better than Tony to talk about this, and I'm very proud to introduce to you Tony Hemmelgarn, CEO for DI Software, to explain this more.
Innovators, engineers, and makers will never run out of new ideas. The opportunities for creation are truly endless. I'm excited to share a little bit more about Siemens software. We help our customers with these creation opportunities, from the factory to the products they manufacture. Earlier, Cedrik talked about how much of it is enabled by our software. We build a unique software core that allows us to continue to grow our digital business and puts us in the perfect position to transform the market. It's a truly amazing business, and I've been here since the beginning working on this vision, an idea we started when we became a part of Siemens 14 years ago. We focused on helping our customers with the entire product lifecycle, everything from design to manufacturing engineering, to production, to the service of the product.
Our software helps design and simulate the entire factory before it's built. We optimize the layout. We define the work cell design. We program the robots. Many software tools claim to do this, but our value is clear. We do this simultaneously. We integrate all the pieces together because many times the complexity is when all the processes interact. We can also simulate how the machines and humans complement each other, something very important when you think about the factory of the future. Our software can help us avoid issues like fatigue, injury, stress. We use virtual humans to test and improve the safety in the workplace. These are just a few examples of our software capabilities, solutions that have helped us partner and transform the world's most innovative customers. These relationships have helped Siemens grow into the number one industrial software company.
Our growth is driven by a unique strategy, a strategy built on comprehensive, personalized, and open. This strategy is delivered through a portfolio of software services and domain knowledge, all things needed to help our customers create digital enterprises. We define this portfolio as Siemens Xcelerator. When we say we have a comprehensive digital twin, what does it really mean? Well, we create the most complete digital representation of the real product in the factory, and we call it a digital twin. While many companies talk about a digital twin, no one offers a comprehensive digital twin like we do. We've built the technology to do this over the past 14 years because we know the value of the digital twin is how closely the digital represents the real. Industrial software, like all software, continues to evolve. For example, I spent many years working with our customer, Ford.
At the time, it was one of the most complex PLM deployments in the world, and we created everything in 3D models to make sure the car would fit together. These techniques, they changed forever the ideas of design and manufacturing. Our customers, they wanted more. Designing and simulating the parts of this Maserati all coming together, it's important, but they also needed to understand how the car would perform. What about the handling? What about the comfort? What about the noise? For example, how effective is the shape of the automobile in reducing air resistance? Our customers also knew the digital twin would be better if we could represent not only the mechanical design, but also the electronics. We acquired Mentor Graphics for electronics and semiconductor design, now known as Siemens EDA. We realized something interesting.
We know the design, the manufacturing engineering of a product. Our automation tools help run the factory. With all this information, how can we better help our customers? We simulate, predict, and capture insights digitally across the product design and production process. We feed the data back into our digital twin to better influence the design. This is accomplished through our industrial IoT solution, MindSphere. At Siemens, we cover the complex process more comprehensively than anyone else. We help our customers. We help our customers use complexity as a competitive advantage. What do I mean by competitive advantage? Let's look at our customer, Bye Aerospace. They had a big challenge. They're building an electric airplane for use in general aviation. They can't afford a lot of mistakes. They can't do a lot of physical prototype builds. They needed to get it right virtually.
The engineers found a problem with the stability of the plane. Almost every part of the plane had to be redesigned or relocated. The digital twin of the plane enabled Bye engineers to redesign, test, and create reports for certification, doing all of this while working from home because of COVID, and they did it in seven days. Seven days. The process of design and manufacturing can be truly complex. Using our software cannot be. It must be intuitive, and we believe software will become personalized. We acquired Mendix in 2018. It truly lets users, not software developers, but users, create and tailor our software applications. For example, someone in purchasing might create an app to view product designs like this razor and then grab cost information from their ERP system in just the way they want to see it.
The value of our solutions is clear, but we also know information must flow easily for our customers. That's why a flexible open ecosystem is a critical part of our strategy, and there's strength in numbers. Our 3D modeling engine, our 3D visualization products have millions of users, and they're used by our competition as well, allowing data to move more seamlessly for our customers. When our customers want to make new applications faster, they can benefit from nearly 200,000 developers in our ecosystem. Thanks to the recently announced acquisition of Supplyframe, we added another 10 million users to our ecosystem. These users, they perform over 400 million search requests a year. We started 14 years ago in Siemens. We expanded our accelerator portfolio through a combination of strong organic growth, along with 30 acquisitions, more than 30 acquisitions, done at very favorable multiples.
We've almost quadrupled the software business. We've expanded our market by 50%, by over 50%, generating over EUR 4 billion in annual revenue. We've become number one, with more than 170,000 customers adopting our software. The pursuit to improve quality, reduce cost, and quickly respond to changing market dynamics and do this in a sustainable way, that's never finished. For example, companies like Polar, they make sports watches for athletes. They're in an endless search to improve battery performance or features or capabilities. Frankly, if you have a digital watch, there's a good chance it's designed in our software. We look back at companies which thrive during the global pandemic, they're the ones that have embraced digitalization. Because of this trend, we continue to see an increased demand for digital transformation.
Because of the vision we started years ago, no company, no company is better positioned than Siemens to help customers become digital enterprises. Earlier I mentioned MindSphere IoT, where we learn from the data we produce. We bring this data together through a convergence of sensors on the shop floor to the industrial edge devices. We combine that with our accelerator cloud software portfolio. We call this sensor to edge to cloud. These digital advances truly unlock opportunities for our customers. Our work with Coca-Cola is a great example of this. Coca-Cola has very aggressive sustainability goals. They wanted to improve the efficiency of their plant. They needed predictive maintenance tools, operator alerts, automatic tracking tools, all operating as personalized applications running on mobile devices. We proposed our MindSphere Industrial IoT solution to improve resource efficiency. In the first six months using MindSphere, they eliminated four major downtimes.
They had over a 4% reduction in equipment performance loss. They reduced energy usage by 13% and a savings of €110,000 in the first year. Now, imagine trying to compete when your competition embraces digitalization and receives these kinds of returns that quickly, and you're not. Examples like these are some of the reasons why our customers stay with us for a very long time. Those in the boardroom, they see that Siemens has a direct impact on their bottom line. It's one of the reasons our software business is a very sticky business. Our customer is at the center of all we do, and they tell us what they want. They ask for solutions that are easier to access, solutions that can ramp up engineering capabilities on demand, and the flexibility to securely collaborate from anywhere, anytime.
To best support our customers as they transform their business, we must continue to transform our own. Our customers are asking us for software as a service, SaaS. They can subscribe to new accelerator services that leverage the power of the cloud. We've been investing in the cloud solutions like Mendix and MindSphere. We've placed applications like our industry-leading PLM Teamcenter in the cloud with Teamcenter X, giving our customers tremendous flexibility. SaaS offers benefits to customers of all sizes. Imagine you're a large appliance manufacturer. You're developing a new dishwasher. The design engineer needs to worry about style and functionality. In an ad hoc collaboration over the cloud, the designer works with another engineer on simulating the performance of the dishwasher. What about the design engineer's potential customer? Let's use a digital twin for quick feedback from the customer.
The customer leverages augmented reality to see how it looks in their home. As the customer is reviewing the design, we simultaneously get the engineering models into our global supply chain. The supply chain can ramp up software needs quickly so they can scale up their production, all from any device, anytime, anywhere. Now visualize being a small company with a global footprint, Rorick Bikes. Even though it's a small company, they need to access many of the same solutions as a large company. They don't have a dedicated IT department. They need us to manage it for them. They outsource their IT to us, which allows them to focus on innovation. SaaS enables us to offer benefits to customers of all sizes, regardless of industry. It also provides easier, more affordable access for small organizations to use high-end capabilities that scale as they grow.
Our customers will continue to use our proven software solutions. Now they can subscribe to cloud capabilities that are fully integrated into those workflows. We also benefit. Through the cloud, we can reach new markets and new users we may not have been able to get to previously. New customers like Ruroc that need us to manage their IT for them. We can provide new offerings and new ways of working that help our customers scale on demand. While the value of SaaS is clear, we're giving our customers the freedom of choice. Choice of perpetual or subscription, choice of on-premise or cloud. Of course, we think most will choose SaaS. Why? SaaS gives the highest degree of flexibility and personalization, and we let them set the pace of this transition. We also have a transition as we move to SaaS.
It will trigger a shift from upfront to ratable revenue. This transition will drive more resilient, predictable growth. Like other software companies making the move from perpetual to SaaS, the lifetime value per customer is higher. This increased value per customer is driven by additional monetization opportunities, like value-add cloud services, or as we capture customer insights, more personalized solutions. We see increasing revenue through pay-per-use access to higher-end capabilities. For example, simulating the thermal and structural impact of a car entering the water requires high-end software and a lot of domain knowledge. Let's go back to Rurok Industries. What if they want to simulate the air resistance on the bike? They don't have the in-house IT. They don't have the compute infrastructure. They still have the need. With SaaS, we can reach a customer like Rurok with our cloud offerings.
They outsource the IT to us and the issues they have to us so they can focus on the product and their customer. We plan to begin this transformation with our core PLM customers. As our EDA customers' requirements evolve, they will transform as well. Software revenue will continue to grow, but as a result of this new revenue recognition model, it will not be as fast as our annual recurring revenue, ARR, which has a high degree of visibility, is much more resilient. Our ARR is expected to grow by greater than 10% CAGR between now and the fiscal year 2025. You'll hear more about this from Rudi in a moment. Now, because no revenue is truly recurring, we will continue to invest in the cloud with a focus on industry solutions, go-to-market, and customer success, all factors to improve the quality of recurring revenue.
Rudi will go into this in a little bit more detail in our investment plans. We believe it is clear that a digitalization strategy can be the true difference between the most and least progressive companies. Siemens' Digital Industries Software makes a difference for our customers. They stay with us for a long time because we help them drive digital transformation. We grow the digital and transform into a SaaS business, software will continue to deliver great value to Siemens and to our customers.
Thanks, Tony. It is clear DI is about high-value growth and transformation. Why? First, because we have so many existing customers. In the first half year of FY 2021, 70% of our existing customers bought from us again, and they bought more than the rest of our customers. This is called land and expand. Roland calls it growing the core. It's definitely a huge opportunity we're going to focus on. A second example, Volkswagen. We're doing co-creation with Volkswagen. We're working with them to link the existing operation and automation to the cloud, making automation much more powerful. They want to create an open cloud platform for their 122 factories to accelerate productions, logistics, supply chain management, and then they want to extend it into new open markets. With MindSphere and our domain know-how, we stand by their side. Second, we will continue to grow in verticals.
We're already number one in automotive. We're number 1 in chemicals, and now we're also number 1 in automation for food and beverage. You've already heard from Roland Busch about the bottling company Swire Coca-Cola in China. We're helping them. We're helping them unlock annual production capacity of 550 million cans, and we're helping them build 18 future digital plants. When we talk about scale, that's what we mean when we go into our verticals. We want to take this into other growing verticals, pharma, batteries, electronics. Third, we are broadening our footprint of Industry 4.0 with small and medium-sized businesses. They will benefit most from digitalization and automation. We already have a market share of about 40% in large enterprises, but only 20% in SMEs. We want to push into this business up to the same level as in large enterprises, making it easier for SMEs to use this technology.
We will offer them new business models like SaaS, Tony just mentioned, and new ways of working, like low-code development, and we will even include financing solution with our Siemens Financial Services. We already heard about a company which used to be small, BioNTech. It's not small anymore. There are many others. For example, small craft breweries like the Australian microbrewery, Wolf of the Willows, who produces beers for pubs. They're fully automated, combined with digital solutions. When COVID struck and pubs closed, they could quickly switch to beers for individual consumers, and they reduced ferment time from 25 to 18 days. SMEs are an attractive market, and we're ready to go forward in it. Finally, it is regional growth. In the fast-growing markets like Asia, we have a leading position, including in China. We have been there from the beginning.
We also address further growing markets like India or Vietnam. Think of the example of Vingroup. Our strengths in software will help us grow in the other markets like the U.S. and Japan. This is what makes us strong. We're close to our customers. We're investing continuously in innovation. We're building strong ecosystems. Where we need a stronger DNA for this, we strengthen it through acquisitions. That's how we become the number one. We want to expand it. How? By selling more of our unique automation and digitalization capabilities to our existing customers, into new verticals that aren't as advanced yet, to small and medium enterprises, making digitalization simpler for them, and by going early into regions that will grow over the next decades. This will give us profitable growth for the years to come.
It must be based on a stringent capital allocation, of course. Handing over to Rudi, our DI CFO.
Thank you very much, Cedrik. It's a pleasure for me to speak with all of you today, and I'm sure you will all agree that DI has an exciting future. Not only is it a great business, as Cedrik pointed out from a technology side, but it's also a great business from a financial perspective. Just look at our first half-year financials, where we were able to grow revenue by 9% year-over-year comparable, thereby clearly outperforming our competition. A profit margin of 21% is a testament to the profitable portfolio and productivity culture. Let me start my presentation with my top priorities to take DI even to the next level. The first one being continuous productivity. In DI, we have a strong execution discipline.
Testament is our DI One Program commitment at the 2019 Capital Market Day, where we not only accelerated by two years, but we also increased savings up to EUR 420 million. You would ask, how did we do this? Well, Cedrik told you, we drink our own champagne, which means we deploy our own technologies in our own factories and internal operations, enabling us to be even stronger coming out of the market contraction in the last months. Going forward, we will continue to deliver productivity and improve the flexibility of our cost structures. We will do that by focusing on levers like digitalization, balanced global value chain, an actively managed portfolio, making sure our go-to-market is future-ready, and implementation of the new normal, which refers to the transformation in new ways of working. My third priority is asset management and strong cash conversion from profit.
Evidence of our strength can be witnessed in our strong first half-year financials, where we not only have been able to grow profitably, but also convert profits into cash to reach EUR 1.6 billion of cash and achieve the cash conversion rate target. Next would be stringent capital allocation. In Digital Industries, we have many good ideas where to invest. These ideas are always carefully evaluated to pass our capital allocation quality gates to ensure investments with the highest returns for DI. As Cedrik and Tony have explained earlier, we have selected focused investment areas that we believe cement our leadership position and prepares us for future profitable growth, such as leveraging on digitalization to ensure our go-to-market is future fit, investing in the evolution of industrial operations for discrete and process automation, building ecosystems to provide scalable cloud and edge solutions for discrete and process industries.
Last but certainly not least is business model transformation. Tony spoke about how we grew into the number one industrial software company, and how we will leverage our position of strength to transform our software portfolio into cloud-based SaaS offerings. Let me explain this business model transformation from a financial perspective and provide you some more information on our software business. Software accounts for 28% of our current top-line revenue. Within software, we have three major business types. Product lifecycle management with 65% share, we have electronic design automation software, also known as EDA, with 33% share, and the balance being cloud offerings like MindSphere and Mendix. Starting in 2022, we will incrementally transition large part of our portfolio, mainly PLM, where our customers are consistently asking us to offer such solutions into SaaS fully rentable revenue recognition model.
This transition is optional based on our customer readiness, as Tony has already explained. A portion of software revenue will remain in the non-rentable revenue recognition model until customers are finally ready to transform. As Tony said, recurring business are nothing new to us. We started very early to continuously migrate our business away from perpetual licensing. Today, recurring business models already account for 70% of our DI Software revenue, and we firmly believe that subscriptions are a much more resilient way to deliver continuous value, not only for our customers, but also for Siemens. Recurring business models will be at the core of our software business going forward. To monitor this development, we are introducing the KPI annual recurring revenue, or ARR for short. I'm pleased today that we will disclose this KPI to the capital markets on an ongoing basis.
With already approximately EUR 2.6 billion today, ARR already represents a large share of our business. We expect significant accretive growth with a CAGR above 10% until 2025. By the way, as evidence of resilience, ARR was growing even faster than our software business during the year of the pandemic. To further drive the software business transition, we will continue investing in the cloud to enable cloud-based SaaS and hypergrowth cloud business. This creates cloud-based ARR, which is highly attractive for future resilient growth, and we expect it will represent more than 40% of our subscription business by 2025. Next, I'd like to talk about revenue and what is changing. Our customers transitioning to SaaS will trigger a shift from upfront to rentable revenue recognition. In other words, shifting from perpetual licensing models and on-site subscription models to SaaS and cloud-based subscription models. This will drive resilient, more predictable growth.
As our customers will have a choice of business models, some may not transition in immediately. This part of the revenue will continue to be recognized largely upfront. Despite the revenue recognition effects I just outlined, DI Software will still be able to maintain the level of FY 2021 revenues in FY 2022. From FY 2023 onwards, we expect to return to high single digit or double-digit revenue growth with even significant higher growth potential in the future years. This would confirm the tremendous value we see in this transition. We expect a high adoption rate by our customers as we prove the long-term additional value to them, as outlined by Tony. Following the completion of our Mentor integration, we will continue our cloud investments with a focus on SaaS, and these total investments will continue to stay in the same ballpark as in the past.
The move to SaaS will have an impact on DI's profitability, but we will remain in our target margin bandwidth despite up to 200 basis points margin impact. DI will get back to the FY 2021 profit margin level by year 4. We set the stage today for accelerated and resilient growth in the future, combined with growing margin levels. The impact from the transformation is short, and profit and free cash flow even continues to grow during the transition. Unlike our software competitors, DI has the ability to do a SaaS transition without significant impacts on its overall business KPI. To sum up, out of a position of strength, we will bring new offerings and business models to the market.
ARR is expected to grow by a CAGR of more than 10% until 2025 and will be a key KPI to monitor our software performance in the market. This is the new DI resilience KPI that Ralf was talking about when he introduced the financial framework. DI software revenue will flatten slightly in the short term, FY 2022, due to the accounting effects. Unlike others who have embarked on this transformation, we've been transitioning to recurring revenue models for some time. As a result, I can commit that we will deliver positive cash flow going forward. I'm confident in our business model transformation, and I'm also confident and excited in our market-leading automation business that is entering the golden age of automation and digitalization.
We are convinced that by bringing software and automation closer together in the last decade and starting the next level of automation with digital enterprise, our automation business will continue to create profitable growth and turn investments into value. As Cedrik joins me.
Let's meet team Digital Industries at Siemens and show you our overall commitment going forward. You see, we are committed to success with a market-beating team from both sides. We have Rudy, Tony, Rainer, Achim, Eckhard, Karen, Stefan, Liliana from Siemens, who fully understands all the capabilities we have. We have also people from the outside who bring in their specific know-how. Cedric, you're from Cisco, right? I absolutely did. Who else came from Cisco? Scott is helping us to change our go-to-market. Roland mentioned it, digital offerings require new go-to-market approaches, and Scott is exactly the right guy for this. We also have Brenda, who has worked 23 years at Autodesk before joining Siemens. We recently announced that Dirk, the head of the worldwide IoT activities of Amazon Web Services, is going to join us as our new CTO.
We have the best of two worlds. We are augmenting decades of industrial experience with very diverse backgrounds, helping us to accelerate our profitable growth going forward. Absolutely. I'm proud that the team delivered exceptionally strong results on our prior Capital Market Day commitments. Going forward, you can hold my team and me accountable to deliver over the cycle comparable revenue growth between 5%-7%, growth in annual recurring revenue larger than 10% CAGR, profit margins between 17%-23%, free cash flow continuously increasing year-over-year, and the cash conversion rate continuing on our one minus growth paths. We will achieve all of this while transforming parts of our business to SaaS, which will of course have an impact on growth and profit. Ladies and gentlemen, this is a fantastic business. You saw the H1 results.
We have a huge growth ambition for the next decade. We are confident that we will achieve them. You've heard our customers, and I firmly believe in the golden age of digitalization and automation shaped by Siemens, its customers, and its partners. Now we look forward for answering your questions.
Thank you, Cedrik and Rudy, for this in-depth overview of Digital Industries. We're now ready to answer your questions. Just a quick reminder, please remember to use the blue talk request button or dial star five on your phone. Please limit yourselves to two questions only. With that, let's go straight to Alexander Virgo from Bank of America. Alex, your line is open now.
Thanks very much, everybody. Good morning. Apologies for my video not working. The travails of working from home. Thanks for taking my question. I wondered if you could talk a little bit more about the variations in adoption rates or obstacles to adoption of SaaS by region and vertical. I'm just curious as to where you see the differing growth rates and the differing approaches from a customer perspective, given that's what's driving the growth rather than you pushing it, I suppose.
The follow-up question would be, in light of what you committed to for the software business for FY 2022 and then the implications for 2023 and beyond, I wondered if you could just give us a little bit of color around how you're thinking about the non-software business, given you're still committing to the 5%-7% comparable revenue growth in the next 12-24 months.
Thanks, Alex. I'll give you an overview on the SaaS business. The main idea, we've been doing SaaS for a couple of years now. We have MindSphere, we have Mendix, we have a couple of SaaS elements, so we know actually what happens. There's a couple of benefits for the customers which will drive the adoption. The first one is really it's an easy access to innovation. You're always up to date in terms of the capabilities you have, so that's good. Lower barrier to entrance in terms of CapEx and in terms of ability to scale. We also have flexibility, right? You can basically work with different teams together. What we expect in terms of SaaS is it will definitely start in the PLM space because we have large customers and also small customers which are interested in different parts of our software suite.
In the EDA part, it's going to be more on the PCB side, there where there's more collaboration, et cetera. It's going to be probably a bit slower on the IC side, the integrated circuit part, and Rudy will answer some of those questions also later. I actually believe that PLM will go first, then we will go also on the PCB side for EDA, and IC will take a bit longer, which is also what Rafael alluded to. In terms of regional and in terms of also verticals, but I actually think it's going to start mainly in the SMB side or the small medium businesses, and that's why we actually wanted to sort of address also the SMB part of it. We're also seeing large customers going in this direction. If you think about it, PLM first, EDA, PCB, on the IC later.
If you think of the business as probably more the small and medium, but large customers going in this direction, it's going to go across most of the industries. It's going to be as well in part of automotive as it's going to be part of food and beverage, et cetera. It's actually going to be a broad adoption. The difference is we're going to want to drive it, not force our customers, but prove the value to our customers so they're actually buying into this and going forwards. That's why we were a bit sort of keeping it open. Is it three years, four years? The SaaS adoption, it's going to depend on how much sort of value we can actually drive for them, but we are pretty confident that it will be great value for our customers.
Alexander Virgo, let me pick up on the second part of your question, you were asking 2022 and beyond, the non-software business. I'd like to say that in the last quarters we've seen a very solid pickup of our verticals recovering faster than what we had expected. It's not just that tailwind, it's also our capability to participate in that market recovery. For the automation business, you will see probably in financial year 2022, a rather quick recovery rebounding faster than what we had before. Over the five year cycle, we see that the discrete markets are going to grow by 6% per annum. The process industry is a little bit less, grown about 4%. As Cedrik Neike and Tony Hemmelgarn has outlined, our ambition is not just to grow on the market level, but actually above that.
Okay, great. Thanks, guys. Would you mind just quickly clarifying your exposure to large and SME in terms of the split?
Sorry, what was that, please?
The exposure of large and SME.
We have roughly 40% in large enterprises and 20% in SMEs market share. Our ideas is at the moment that we really are focusing with the SaaS transition also on the SME part of the market.
Great.
Thank you.
Thank you very much, Alex. We now move to the next question, which comes from Gael De Bray from Deutsche Bank. Gael, please go ahead. Your line is open now.
Good morning, everybody. Thanks very much for the opportunity today. The first question I have is about the PLM business that used to be very much driven by automotive and aerospace customers. Both of them put the brakes on spending when the pandemic started, obviously. My question really is, what are your traditional automotive and aerospace customers telling you about their intention to spend on PLM? That's question number one. Question number two is about the success you've had, the great success story you've had in Europe and China over the years at DI. What do you still need to do to be able to replicate the same success in the U.S.? Do you think that the infrastructure programs in the U.S. over there will help you or rather favor maybe some of your already very well-established U.S. local competitors?
Thanks, Gael. If I start with the PLM business, which is the largest part of our business, it is definitely in automotive. The good thing in terms of spending is that we see that whilst our EDA business was on fire over the last couple of quarters, even during the pandemic, automotive and aerospace is starting again to go forward. The main reason is that we have roughly 24 out of the big 25 automotive customers, and I just visited one on Friday. What they're saying is, "Look, we need to put more." Mercedes-Benz is another great example. We need to put more into software because we're moving now to build electromotors. We're building also parts of the battery packs. They're extending their value chain, and they need to digitalize it from the beginning.
What we're seeing is, these customers are not only restarting because of their traditional portfolio, but also because they're changing their portfolio. That's what's happening in terms of PLM, but we're also seeing PLM now being extended into other markets. Our relationship we have with SAP is reselling Teamcenter. We're putting it into their own sort of offering because they want to go into a lot of different other markets with us. That's on the PLM side. It's a business which is accelerating now coming out of the pandemic. It's accelerating the traditional businesses, but it's also accelerating into new verticals, and it's also accelerating with partners we have, such as SAP or Fujitsu in Japan. U.S. is an interesting part because as you said, we're very strong in Europe, we're very strong in China.
We're also very strong in the U.S. and in Japan on the software side of things. That helps us. We're very strong, and as we're connecting more and more the software in the automation side to really build a holistic sort of offering, we are going to enter, and that's the idea we have, and which we're seeing to be successful in being able to actually go through the software side and pulling the automation capabilities going forward. You've seen that we are actually with BioNTech just announced yesterday, the replication of building sort of end-to-end vaccine production on greater scales. Once you have done this, you can actually replicate it in Asia, but you can also replicate it to the U.S.
The U.S. is for us, a market which is high-tech, which we will enter through our strong software business, and we will also enter through the vertical solutions which we build for worldwide level, which we can actually replicate.
Are you able to confirm that the very strong order dynamics we saw in the U.S. at DI in the prior quarter have continued up until recently?
The question is this, we have seen the recovery for our numbers in the U.S., and it's actually accelerating. Sorry, Gael, you also ask on the infrastructure deals which are happening at the moment. I mean, in the U.S. because we have such a footprint, the good thing is we are also seen in the U.S. as a U.S. company because all of the acquisitions we've done on the software side are actually American-based. It's our headquarter there. We absolutely believe that we can participate in the infrastructure acceleration as it moves to industrialization and Industry 4.0, which we are very much leading in the space. That's the main question.
The acceleration on the U.S. market, we're seeing the recovery, and as I said, it was a bit slower because it was so process-heavy, but as the process industry is coming out in the U.S., we're participating in this growth also. Okay. Thanks very much indeed. Thanks.
Thank you, Gael. The next question comes from Simon Toennessen from Jefferies. Simon, please go ahead. No limit this time, other than the two-question limit.
Thank you, Eva. Good morning to both of you. The question on the revenue that I asked earlier has been basically answered, I think, and asked by Alex earlier. If you could just clarify a bit more in terms of next year, in terms of the way you see your guidance range of 5%-7%, assuming software is flat, which is what you're guiding for, it does seem the automation business needs to grow significantly or at least above that range in order for you to get in there. Just to clarify. Two numbers question I have on your presentation. You said you already have 70% of recurring revenue business, and it's a combination of subscription, SaaS, maintenance. Can you break this down in more detail, please?
When I try to do math on your various businesses, I struggle to get to those numbers, given particularly how small SaaS today is. Just as an add-on to that, you mentioned your number two market position in process automation. How do you define that, please?
Okay. To sort of close off the first question, which Roland sort of gone forward with, our goal is to grow profitably. The main idea is that we want to grow faster than the market and take market share, which goes back also to Gael's part. The last quarters actually show the strengths we have on both businesses to be able to completely absorb the SaaS business transition, which is coming over the next three to five years, four years, and Rudy will tell you a bit on the modeling side of things. We're extremely confident that our position, both on the software side, but also on the automation side, enables us to do what we just did, is to keep everything the same, even if we're going through this transition.
On the market position on process, we are very focused on process, to be very honest. We're strong in chemical, for example. We're increasing in strengths on the pharma, as you've seen with BioNTech. We're not as strong on the oil and gas part of the end because we want to focus on markets where we can make a difference with number one and number two positions. As you do the aggregation, actually, you go to the position which we shared with you, but we're trying to be in every market number one or number two in the process. Water is another example in the process side of things, which we think we can make a difference. Simon, I already covered some of the points with Alex, but let me just summarize the key points.
The 5% to 7% growth obviously has firstly the revenue recognition impact that we showed to you coming in the software business. We remain flat in 2022, and then after that, we start picking up our growth again. For the other businesses, the automation side businesses, I mentioned that the discrete business, the market should grow by 6%, process in four. If you model that out, that is what is driving the bandwidth between the 5% to 7%. Coming back to your recurring, and I understood the math doesn't really get out to come back to the full revenue, you need to consider there are other elements in there like service, for example. You said it already, recurring revenue is the sum of our subscription business, it's our SaaS business, and then of course it's our maintenance business.
The maintenance business is typically contracts that we sell together with perpetual deals. This is a subset of the revenue that we have. If you look at the upfront revenue portion that is within the recurring revenue, this is not accounted for when we go into ARR. ARR actually annualizes these multi-year subscriptions to give us a comparable development going forward. I think this is why we are also very happy today to disclose ARR, and because it will be the KPI for you as well to track how are we progressing through the transition with SaaS.
Thank you.
Thank you, Simon. The next question comes from Andre Kukhnin from Credit Suisse. Andre, please go ahead.
Good morning. Thank you very much for taking my questions. I've got two. One is on MindSphere and on how do you assess the development and success of that platform, and from what I understand, it's potentially transitioning towards more apps rather than being platform and how it kind of interacts with some of the tech primes like AWS or Azure or even Google. We'd love to hear your assessment of that. The second question is coming back to that 6% through cycle market growth rate that you have for discrete automation. What assumptions do you bake into that for your traditional automotive supply chain as that transitions to electric vehicles, where obviously bill of materials is much smaller and hence theoretically leads to a much shorter supply chain?
I understand your traditional customers are basically investing now in motors and battery packs, but there's obviously the other end to fall out. I wanted to check on that, please. Thank you.
Good. If I talk about MindSphere, we need to talk about the whole SaaS environment because MindSphere, as Roland was saying, are capabilities and microservices which enables us to glue different elements together. We gave two examples. We're working with Volkswagen to use MindSphere, and MindSphere is one of those elements which enables us to work with, let's say, American cloud providers in Europe or in the U.S., but also with Chinese cloud providers in China. This was going back also to the earlier question. It gives us the flexibility to actually take our apps into different markets. The other part which we also need to understand is that we are moving the sensor to edge to cloud. We believe that a lot of the value will actually be created also on the edge part of the business, and we're investing quite a bit on this.
I always give the example that a factory produces, and this is another auto factory I was last week, roughly 2,200 terabytes of data. You're not going to shift it back to the cloud, but you need to be able to actually take the data which is relevant, put it in the cloud, train your AI, and then put it back onto the edge so that you don't shift it back and forth. MindSphere enables us to do this. The key part of this is that Coca-Cola was the other example, is that MindSphere has helped us start really the IoT market. It's now moving to be the glue with Mendix to all of our SaaS transition, and enables us to be either moving elements from the edge to the cloud or to move it to different cloud providers so that we have that flexibility.
That's the idea of why we invested in MindSphere and the success we have there. You see the market leader position. When you look at Gartner, PAC, Radar, IDC, we're number one really or in the top position in that space of IoT capability. To the very detailed description on what do we believe our auto manufacturers to do, we're seeing this. You have to understand that the complexity of factories and auto manufacturers are increasing because they used to, very few can build an electric car manufacturing plant and actually in parallel, just a pure combustion engine plant. If you go to most of the suppliers, they need to have flexibility to today, do combustion, tomorrow do a hybrid, and then also do the electrical motor.
We think for the next couple of years, there's quite an investment that needs to happen so that you keep the existing production running, but you make it flexible to be able to go to the electrical. On top of what I told Gael, that there's an extension moving into actually the battery production, which is huge, and also the electric motors. We're now moving into flexibilizing these auto plants, which used to be very defined in building one car and build this hyper flexibility into it, which is a lot of automation and a lot of software you need to be able to do this. I think that would be my answer to it. I wouldn't give you a concrete percentage, but we're definitely seeing quite a bit of vitality in the auto market.
Can I just follow up in terms of the supply chain for traditional automotive, all these factories that are now cranking out engine components, gearboxes, fueling systems, et cetera. It sounds like you don't see a potential slowdown from investment automation from them as a threat to that 6% growth?
A lot of them we're actually working, and I'll give you an example. Of the 100 customers I visited since I joined 8 months ago, a lot of them were actually also supplying the auto manufacturer, which built the traditional CNC manufacturing machine tool manufacturing, and they're repositioning. There's the classical, I built the combustion engine environment, but they're repositioning to be able to do hairpin machines, which build for electric motors. They're building packaging capabilities for actually doing battery packs. What's also going to come, all of those things will have to be taken apart going forward. When you now build something, a car, a battery pack, you need to think about how do you take it apart again, and that part needs to also be automated.
The supply chain is actually growing, and as I talk to most of the automotive suppliers and the automotive manufacturers themselves, the OEMs, they're actually in a quite a bit of a renewal of their actually offerings and working with us to be able to do so. If you look just a few numbers, Andre, the machine tool business has come out now strongly again out of the crisis and is accelerating again just in pure numbers.
Thank you very much.
Thanks, Andre.
Thank you. The next question comes from James Moore from Redburn. James, please go ahead. Your line is open. James, can you hear us?
We cannot hear you.
It seems that we may have some technical difficulties. James, what we do is we take the next in line, and then we come back to you. The next in line would be William Mackie from Kepler Cheuvreux. Will, if you're there, your line will be open now. We go down our list. We then go to Martin Wilkie from Citi. Next try, Martin. If you're there, the floor is yours.
Hi, Martin.
We can't hear you yet. You have to activate.
Martin, maybe you're on mute. No, we can't hear you.
Can't hear you yet. Try again, please. Unfortunately, we're experiencing some technical difficulties, and we try again with James. Martin, we try and come back. Let's see if James has figured out the tool. James, are you there?
Hello, everybody. If you can hear me, it's James.
Fantastic. That's great.
I hope you can. Cedrik, Rudolf, I have a question on margin. If the Digital Industries margin goes back to the 2021 level in 2025, how much do you see it falling at the trough? Which year is the trough? Then a question on EDA. You're the number three overall. You're very strong in PCB. You're number two in IC layout, but you are a clear number three in the CAE simulation piece of EDA. What can you do to address that, as it's arguably one of the fast segments going forward? Finally, on EDA margins, consensus for your two competitors goes up from 25% EBIT margins to over 40% in the next three or four years, which is a very significant increase with the high growth and the high gross margins in that market. Do you think you also see strong profitability increase in your Siemens EDA business?
Maybe Cedric, I lead with the first and the third question. Thank you, James, for the question. The first part of what you were quoting is how far is the trough going to be? In the handout in our presentation earlier, we were mentioning 200 basis points that is coming because of the revenue recognition effect. This transition is optional to our customers, we predict a solid development. We would rather see the trough somewhere into 2022. It's up to the speed and the acceptance of our customers, how they are going to adopt into the program. I just want to take the opportunity as well to say that we stay within our profitability bandwidth. As DI now, we are big and strong enough to be able to digest the SaaS transition and stay within our profitability bandwidth.
At the same time, because we've already been from an early point in time transferring from perpetual into subscriptions, we can even build on our cash year by year going forward. The impact is negligible. On the EDA margin, obviously, we do not disclose at that level, but I can do to tell you that we are having a good run, in particular because of the strength within the semiconductor space. We are very well placed there. The EDA business is a highly attractive business for Siemens. I might take the opportunity to place that with you that our EDA IC business is not foreseen now to be part of the SaaS transformation. The business tends to be a little bit chunky or lumpy, depending on the term that you use.
In our case, these contracts are fairly difficult to time, and we definitely do not risk content for timing. You can expect a little bit more of lumpiness within our EDA IC business. Cedrik, on the second question.
James, we're very happy with our EDA margin profile at the moment, and we're nurturing it because if you look at the PCB business, we're number one, we're happy with it. Supplyframe actually pays into the PCB part of the EDA business, but we want to replicate it into other marketplaces. Just to give you a view. One element we haven't shared, but if you looked at the announcement we have, we do quite a bit of investment also into the EDA. In terms of simulation, we bought a lot of, I think nine acquisitions in total, not all in the EDA, but mostly in the EDA space to strengthen it. What we do, we invest in it. We're actually making sure that we're taking them to customers they weren't before, and we're continuously sort of doing, we call them tuck-ins.
I'm not always sure that you like that word, capabilities to be able to close the gap we have and actually take a sort of leap compared to our 2 other competitors. We're happy with it, we invest in it, and we're actually driving, and you've seen the success we have with the EDA business at the moment.
Oh, it froze.
Thank you, James. You do look frozen. I assume we answered your question, and we would be moving on to William Mackie from Kepler Cheuvreux. William, we unfortunately are running out of time, so please limit yourself to the two questions, and these will be the final questions on Digital Industries. Please go ahead. Your line is open.
Hello. I hope you can hear me.
Yes.
Good. Okay. My first question follows up on the subject of margin and development around the SaaS business. I think from the framework that you've given us around the revenue progression in the division for 2022, perhaps you're expecting or anticipating between EUR 600 million or EUR 700 million of revenue to transition as an early stage, you highlighted around PLM. I'm trying to understand the impact that we should take on margin from that. Perhaps you could discuss a little about the gross margin differences between your cloud-based business and the traditional license-based business, and whether there are any other drags to the margin development with regard to a step-up in costs, such as the MindSphere investments. The second question really is to follow up on the Supplyframe acquisition that you made a number of weeks ago.
I think you've been clear about the strategy and what it brings, but could you elaborate a little on how you make the statement that it will be triple digit value enhancing in the midterm? What sort of growth and return expansion assumptions do you build into the growth around Supplyframe and how it complements the existing core? Thank you.
Let me start, Will, I think with your first question. I think you were trying to flesh out on the margins in our software business. Maybe what I could provide you with is further information for your modeling. You've seen from the presentations that we will have a 200 basis point effect in our DI profitability because of the transitioning going into SaaS and the revenue recognition element that is therein. If you were then to probably calculate backwards in your model to understand how profitable the software business is, I'd like to give you two additional elements that you can take with you. One of which we've already alluded to, that as we go into the SaaS transformation, we will start with our PLM part, which the customers are asking for.
We will also go with our IC PCB business, but the EDA IC business will not foresee now in the next wave to be part of the SaaS transitioning. That means that the highly attractive EDA business is not part of the SaaS transitioning. Something for you to think. The second element that I'd like to highlight, I would call it a business mix effect. I'll link it to your second topic, MindSphere, and I'll find my way back. I mentioned to you earlier, in Siemens and in Digital Industries, capital allocation is of really utmost importance for us. As we have been investing to ramp up MindSphere in the past, we've also digested the integration of the Mendix and Mentor acquisitions. We are now refocusing our investments towards SaaS and the cloud. That means that we are reducing our investments in MindSphere significantly after the initial ramp-up effect.
Coming back to the software margin, there is the element of Mendix. Mendix is in a hyper-growth trajectory, and it is on a different business development cyclical profitability effect. Combining the EDA IC effect together with the business mix effect, I think is what you are probably lacking in your modeling. On the Supplyframe, the idea is that this is really sort of a marketplace where you actually are bringing together the producers or the distributors of EDA elements with actually the people which are designing those. This has actually three businesses. This has one business where this is classical, if you think about it, like you're on a website and you get sort of redirected to it. That's the classical business. The second business is actually a business where you do a search.
You're an engineer, you do a search, and you have the capabilities on which element do I need, and you get basically number one, number two, number three. These are the three suppliers which you can have. Now, the element we're transitioning and which has this hyper-growth you're alluding to is the capability that we will offer SaaS components. Because we have the SaaS components I mentioned, we have sort of a freemium model in which you start designing your PCBs and you get sponsored by the people which actually are putting the different elements on it. That's what's actually driving this growth and the numbers which we shared with the market in terms of where we're going forward. Now, this is just on its own good for the EDA business because it's extending the supply chain if you want.
What's the big kicker into this is once you know on how to build those marketplaces, you can extend them into mechanical and other elements, which is what the plan for us is. Our idea really is that Supplyframe becomes the kernel on doing these marketplaces. Imagine you have Teamcenter and you have a BOM of your product, and like at the moment, there's a certain part which is missing, and you automatically link to the complete marketplace to see where you can get sort of the replacement. That's where we want to go. Supplyframe for me has this hyper-growth due to the fact that we're taking it into our sales channels, we're bringing it forward, but we're going to integrate it also into our products and replicate into different businesses. Well, let me wrap that up with a short fact.
The SaaS business in Supplyframe has been growing by a CAGR of approximately 40% now in the recent past.
Thank you.
Thank you, Will. Thank you all for your very good questions, and thank you, Cedric and Rudy, for your great answers and the passion and energy you've brought to this space.
Thank you.
Here's just a quick reminder. If we didn't answer all your questions, please feel free to send them to us at investorrelations@siemens.com, so we can bundle them into our fireside chat at the end of the CMD. Unfortunately, we're running a little bit out of time, so we have shortened the break to five minutes only. I hope that is okay, and I'll see you back in five minutes. Thank you. Welcome back to our double-header on two excellent businesses. First, we focus on Smart Infrastructure, where CEO Matthias Rebellius and CFO Axel Meier will give you some deep insights into the setup of Smart Infrastructure and the strategy going forward. This is followed by Mobility. Here, CEO Michael Peter and CFO Karl Blaim will give you their insights into their strategy targets and how to accelerate high-value growth.
Now, for those of you who have checked our websites, the handouts for SI and Mobility are now available. With that, directly over to Matthias.
Welcome back, everyone. There has never been a better time to care about our infrastructure. The world is at a point of inflection. Individuals, companies, and governments are posing important questions about sustainable development, and there is a sense of urgency for change, not just about climate change, it's about much more. Radical electrification, urbanization, the need to feel safe in buildings post-COVID-19. Digitalization is the key enabler. The good news is that governments around the world have serious green investment plans to build back better. Smart Infrastructure is crucial to a sustainable energy transition and creating sustainable communities. The energy transition is a major driver of change. We need smarter technology to move to a decentralized, decarbonized ecosystem.
Energy sources are going from around 80% fossil fuels today to 80% renewables. We are moving to an all-electric world. Think about growing demand for electric cars and buses, streaming, digitalization, a boom in data centers. This will increase electricity demand by 20% in the next decade. The changes are pushing aging grids to their limits. Storms, floods, droughts, and wildfires make the need for change even more urgent. During last year's wildfires in California, the community in Blue Lake Rancheria was able to provide life-saving medical care and shelter to neighboring districts hit by blackouts because they had invested in a microgrid, of course, from Siemens. It goes beyond energy. The second driver is the desire to create sustainable communities, the best possible places for us to live and work.
Buildings account for 40% of the global energy demand, and incredibly, one-third of that is wasted. This represents a huge opportunity and a responsibility. It's more than energy efficiency. We want adaptive buildings that are smart. COVID has changed how we think of the indoors. Rather than being a haven, we worry about air quality and social distance. Human-centric smart buildings make us more comfortable, safe, and secure. In the decentralized energy ecosystems, buildings and grids interact. This is Smart Infrastructure. We are well-positioned to create environments that care. Let's look together at our markets. We address electrification, buildings, and electrical products. The infrastructure market is worth approximately EUR 185 billion, with an approximately 3% compound annual growth rate in line with the GDP. It is an attractive market with exciting growth pockets, double-digit growth in both digitalization and at the grid edge.
As you know, the grid edge means electric vehicle charging, decentralized energy systems and storage, et cetera. Let me explain how Smart Infrastructure is addressing these markets. Firstly, with our electrification portfolio. We make grids more resilient, flexible, and efficient. We do so with grid control, protection and automation, switchgear, and electric vehicle charging systems and infrastructure, generating non-consolidated revenues of EUR 4 billion last year. This is a strong core and well-positioned to capture growth in software and at the grid edge. Secondly, our buildings business, which responds to the needs of operators, owners, occupants, and users. With revenues of EUR 6.9 billion, it has a mix of products, solutions, and services in energy efficiency, building automation, fire safety, and security. Here we are uniquely positioned in terms of customer proximity.
Thirdly, our excellent electrical products as the glue of Smart Infrastructure across electrification and buildings, generating revenues of EUR 3.7 billion with protection, switching, and control products that are increasingly connected. We have been outgrowing the market for the past 1.5 years while continuously improving our profitability. Let's zoom in to three examples, one in each area, how we create value for our customers and shareholders. Starting with electrification, we are leading in smart electrification with a best-in-class portfolio. What are the key challenges our customers face? Grids are becoming much more complex. The addition of distributed energy resources will increase by a factor of seven by 2030. It's only possible to maintain grid stability with digitalization. Let's not forget, only 10%-15% of secondary distribution grids are smart today. This is where we come in. Here you see a secondary substation.
Every town and city has at least one where power is being stepped down to go where we are using electricity. We support our customers with leading portfolios for substation automation and protection and medium voltage switchgear. The highlight is here our first to market blue GIS Clean Air range, which is completely F-gas free. As you may know, fluorinated gases are among the most potent greenhouse emissions. We offer increasingly connected and data-enabled services for real-time grid diagnostics, as well as asset optimization. To support the rapid growth in e-mobility, we have strongly invested in a complete range of charging products and services. At the grid edge, energy storage is booming, with installed capacity growing at about 40% each year. Our joint venture, Fluence, is the number 1 utility energy storage company, recently valued at $1 billion, a unicorn.
Let me share an example of how this all comes together in just one city. For many years, Siemens has been supporting Hamburg with its green ambitions. We have a pilot with Stromnetz Hamburg to digitalize the secondary distribution grid. Hamburg will have 50,000 electric and hybrid cars by 2024. Even when we are in a new normal, many people will arrive home and at the same time plug in their e-car, creating significant load on the grid. Artificial intelligence now instructs e-car charging stations to draw less power if overload situations arise and to draw more when there is surplus of power. Additionally, we are installing 96 charging points ready to expand e-buses to a fleet of 1,000 over time. By the way, with the ship-to-shore power solution and our control products making the harbor's fireboats smarter, we are helping on land and at sea.
We're adding value in several ways. We are market leader and areas of our portfolio have class-leading profitability, ideally positioned for strong growth. We can scale. We will see a major ramp-up of demand for electric charging based on a market growing 30% between 2020 and 2025. With our investments, this will be a real growth rocket. The Hamburg example shows the potential in just one city. Let's look at the second example. Buildings are playing an ever more important role in a decentralized energy ecosystem. Here we have a resilient service business with a high proportion of recurring revenue. We already generate services revenue of EUR 3.2 billion annually with 750,000 existing customers as a foundation. Solutions and service go hand in hand with our business model, of course, positively impacting our return on capital employed.
Our customers' biggest challenge is to run buildings as efficient and sustainable as possible with the lowest operating cost and the highest rental yield. Customers need us to make this easier for them. We are well-positioned to support with our service portfolio for buildings with unique customer proximity. We have 10,000 service technicians in the field, and imagine already 2.3 million connected devices. We offer services for single domains such as fire safety and security in just 1 building, but also complete building automation and energy management, or even full service and maintenance of large campuses. IoT and cloud technology are enabling the next step, increasing building efficiency with remote maintenance and decision-making based on analytics. We are taking our customers on a journey from traditional break-fix, with technicians being called to site, to product-agnostic, data-driven services supported by a remote digital service center.
Insights from these services help identify new customer needs, a virtual circle. Let me explain further with a customer example from Dallas, Texas. two years ago, I shared the story of Southern Methodist University or SMU. This university has more than 100 buildings of all types and a great example of a typical campus customer. Since 2019, we have further expanded our strong partnership with new digital services, connecting to our digital service centers. Services can be taken to the next level with cloud-based energy monitoring and analytics and strategic energy planning. The customer's investments in these new services gives them great payback. 60% of all issues can now be resolved remotely, and they save EUR millions in their overall maintenance budget for the facilities. Their CFO put it at best. Let's hear what she has to say.
We have built a good level of trust where I feel they're bringing appropriate solutions to the campus. They have lived on this campus now. They understand how we operate. They understand what our needs are, and I think they've got a proven track record of bringing to us solutions that work.
To summarize the value, the smart buildings market is growing fast, from EUR 15 billion-EUR 50 billion by 2030. Service is a good business, generating recurring revenue based on low capital investments. The data-driven services are higher margin business, with the demand accelerating at a double-digit growth rate. Our third example, last but not least, our hidden gem, the fast-growing, increasingly profitable electrical products business. These products are the magic behind the scenes. What are our customers looking for? In both the markets for electrification and buildings, customers demand reliable products to make whole systems safe and efficient, ultimately protecting people and assets. In addition, customers want more operational transparency to take energy and optimization of assets to the next level. Less downtime means lower operating costs. What is Siemens doing here? Our equipment secures safe and reliable electrical power supply everywhere you look.
Across residential or office buildings, factories, solar parks, ships, or tunnels. We have invested in growth and innovation. During the past five years, 75% of our portfolio has been renewed, increasingly connected to the cloud. Here's a nice example of the magic working for a customer. In Hangzhou, China, we provided reliable power supply for the expansion of their metro network, 300 kilometers with 230 metro stations. Think of being underground, the space is limited. We were able to design compact solutions and provided state-of-the-art circuit breakers and contactors to our license partner, who built these into more than 4,000 compact panels in substations along the metro lines. It's an example where Siemens Financial Services also supported with an attractive financing solution. As our channel partner confirmed, we provided excellent quality, which is why they choose us rather than a lower priced alternative.
Electrical products bring significant and increasing value for customers and shareholders. Products are the backbone of grids, buildings, and industry. Customers appreciate our quality and innovation, and high margin products are positive for our mix. We have a strong track record and maintain solid double-digit profitability while investing for growth, and we can build on this. Opportunities for growth in Asia are supported by our recent C&S acquisition in India and with continued growth with our channel partners. It's time to benefit from these investments and to continue to grow at twice the market rate. Now let's look at our business from different perspectives. First, again, from a portfolio view, electrification, buildings, and electrical products. They all serve three main customer groups.
Close to 60% of our business is with buildings and campus customers, 25% with industrial customers, where we collaborate closely with our Digital Industries colleagues, almost 20% is with utility customers. We benefit from a resilient business mix, as we saw during the pandemic recently. Products with higher margins, services with an increasing portion of digital services, and a significant share of recurring revenue. Our systems, solutions, and software enable pull-through of both products and services. Together with services, they ensure and leverage customer proximity, a base for innovation and growth. We are well-balanced when it comes to the geography, with a strong footprint in Europe and the Americas, and upside potential in Asia.
Having given you now some specific examples of value creation and the flavor of our business mix, I now welcome our CFO, Axel, who will give you an update on our strong performance since Capital Market Day 2019 and explain the ongoing impact of our competitiveness program.
Thank you, Matthias. Before I go in detail, I'd like to share with you how I see Smart Infrastructure and what drives our agenda. We're in the right markets that are growing and have pockets for accelerated growth. We have the technology, the products, solutions, and the right people to address our opportunities. Our business mix has proven to be resilient, and I couldn't be prouder of our performance during a turbulent period. We focus on execution, strengthening capital allocation, and cash flow generation. We've come a long way, and we're delivering on the commitments for fiscal 2021, which we gave at the last Capital Market Day. More importantly, we still have room to grow and improve profitability. Each area of our businesses is committed to close the gap to their best-performing competitors by 2025 at the latest.
Strong execution of our competitiveness program is key and needs to shift from program to process. Strengthening capital allocation is fundamental to sustainable future performance. Here we can do better and need to be more aggressive. As a team, we are focused on being a reliable performer each and every quarter. I want to share more detail of our competitiveness program, the foundation for our continuously improving profit margin. The competitiveness program announced at Capital Market Day 2019 is not a simple cost reduction exercise. It's about systematic, continuous improvement. Our commitment was to achieve a EUR 400 million improvement on top of base productivity by the end of 2023, of which EUR 300 million is cost out. We're now at the midpoint. I'm pleased to say that with a EUR 300 million contribution, we will overachieve by the end of this fiscal year.
We have raised the program goals multiple times and now aim for EUR 520 million by the end of 2023. Our program is built on three axes: optimizing business mix, product and system business improvements, and focusing on becoming lean. There are multiple levers under each axis. I'd like to highlight three examples to give you a flavor. There's much more to it. First, we reviewed EUR 2 million of portfolio based on strategic fit and performance. We exited EUR 700 million. Big ones were HOBO Control and Distribution Transformer. The remainder is under performance improvement program, where up to this point, we have improved profitability by 40 basis points. While we continue to improve, EUR 500 million has been identified for further divestment and M&A considerations. Manufacturing optimization is another important lever. We're well on track. We reduced the number of our production sites by 25%, from 79 to 59.
While footprint considerations will remain, we shifted the focus towards digitalization and automation, and here we clearly tap into the expertise of Digital Industries. Finally, our lean setup. We aimed at simplifying our organization as well as stressing back-office activities by offshoring and/or automating them. As of now, we identified up to 2,200 jobs worldwide in engineering, sales, and administration services, which can be reduced or transferred from high to low-cost countries. Approximately 500 have already moved, with detailed plans in place for the remainder through fiscal 2023. To reiterate, we are committed to deliver EUR 520 million by fiscal 2023. We are well on the way, and there's more potential, and we will go for it. Additional focus is on our service push and pricing, and we will pursue additional portfolio improvement opportunities.
The next step is to move from a program to an embedded continuous improvement process, avoiding major restructuring risks. We've made good progress in optimizing our businesses. This is the solid foundation to address future opportunities. Now back to Matthias.
Thank you, Axel. So far, we have talked about our markets, our business, and how to grow our core. We have explained how we will continuously improve our financial performance. Now let me add some more flavor on two important building blocks: digitalization and sustainability. Digitalization is the brain to simplify complexity, combining the real and the digital worlds across infrastructure. You heard from Roland today how this runs across our entire company. The market for digitalization and software in grids and buildings is growing more than 10%. Having started early, we are in an excellent position to turn this into value for customers as well as shareholders. Let's think about the billions of gigabytes generated, collected, and processed in infrastructure every single minute. Imagine this data being pulled together and turned into a competitive advantage. Advanced analytics turning data into insights to automate infrastructure, even make it autonomous.
Digital twins will be the single source of truth of data over the entire lifecycle of grids and buildings. Digital Industries has brought the benefits of digital twins to industry. The next frontier is infrastructure. Allow me to outline how digital twins bring value. In grids, we have a great opportunity here. Let's quickly recap. Grids are rapidly becoming more and more complex, changing loads, increased demand, more storage, buildings becoming prosumers. Today, information is siloed within separate processes, departments, and software tools for planning, simulation, operation, and maintenance. This is resource-heavy work, and a grid control room can have up to 15 people who monitor the grid twenty-four-seven. With a huge increase in data and complexity, it won't be possible to maintain grid stability at an affordable cost. The current approach won't work beyond the next 5 to 10 years.
Digital twins can help with decision-making across all the domains and processes. The good news is we have a head start. With our leading portfolio and a customer base in grid simulation, operation, and smart metering, connecting our simulation tools to grid operations now enables near real-time optimization. Let me share a great example. Together with one of the largest utility companies in the U.S., American Electric Power, with our digital twin, we are integrating the data from three regional grid operators into one software model. This improves decision-making, which strengthens up overall grid reliability and stability. The twin reduces the time and cost for model coordination. In buildings, it's time to make smart technology work across all aspects of life and work. We talked about only 10% to 15% of distribution grids being smart. For buildings, it's even less.
We need to balance requirements for multiple stakeholders, owner, facility manager, service engineer, tenant. The challenge is that they have each multiple programs and tools to operate the building. This adds complexity and means that as with grids, data is siloed. This is a major source of inefficiency that creates a lot of extra and manual work. This needs to change. Smart technology allows buildings to respond to our needs for wellbeing, comfort, safety, while minimizing operating costs. Smart buildings will conserve energy, facilitate social distancing, and equipment will always be in good condition and in the right place. What is our role in this? We make smart buildings twice. First, we create them digitally, and then we make them for real. We create one simple-to-use interface, a single pane of glass for all the stakeholders to interact with the building and get what they need.
We already have more than 150 digital applications and offerings. This is what Roland refers to as grow the digital. We're ready to take it 1 step further. Our new smart building software suite leverages digital twin technology, analyzing all data to create that single source of truth for a step change in building operations performance. The beauty of all this. Not only do smart buildings use 20%-30% less energy, but also tenants are willing to pay around 10% more rent. We have already pioneered the digital twin approach in a pilot for the Tiefenau Hospital in Bern, Switzerland. We integrated data from building information modeling together with data from the building management system, achieving a 10% total operating cost reduction and 30% faster fault resolution for the hospital. We have been in these businesses for decades, developing deep domain know-how.
We have a broad software portfolio covering both IT and OT, and we are investing for the future. We have a bold ambition: to more than double our digital revenues from EUR 700 million today to EUR 1.5 billion by FY 2025. If digitalization is the brain, sustainability is the heart. Smart Infrastructure is sustainable infrastructure. We empower our customers for their own sustainability ambitions.
Already today, more than one-third of our revenue is from our environmental portfolio. Smart Infrastructure makes a significant contribution to our ESG goals. For example, the D in the DEGREE framework. Let's look at decarbonization. Our carbon-neutral programs support customers towards low or net zero CO2 emission goals. Many of these are enterprise customers. You heard earlier about the work we do with Mercedes as an example. Of course, we also start at home, supporting the whole of Siemens with our expertise to have net zero operations by 2030, as Judith explained earlier. It goes beyond decarbonization programs. In the Azores, for example, we have worked with Terceira Island to deliver a microgrid and battery storage to improve their grid resilience. This solution will enable the island to increase their renewable energy share to around 60% and reduce the annual CO2 emissions by more than 3,500 tons.
Now imagine the impact as we can scale this up over the next years. This is where Smart Infrastructure has an important role to play. We enable the energy transition with our smart electrification, and we contribute to sustainable communities by creating smart buildings, which can deliver up to 25% energy savings and reduce CO2 emissions. With our energy and performance services, we already today guarantee EUR 4 billion savings for our customers. We have the hardware, the software, and the expertise, and we will continue to leverage digitalization and sustainability for further business success. Axel, please join me again on stage. Bringing it all together, building on our strong performance and the progress made in our competitiveness program, we've updated our financial commitments. We commit to comparable revenue growth of 4%-6%. Service is a growth engine for us.
Here, we're aiming for accelerated growth of 6%-9%. These are our resilient revenues, as explained by Ralph. To reflect on improved profitability, we have revised our margin band to 11%-16%. The next step will be a profit margin of 13%-15% by 2023. Last but not least, we maintain a 1 minus growth ambition for cash conversion rate. We have already momentum we can build on. Based on solid plans, the progress made, I am confident that we will continue to deliver. Smart Infrastructure is a business whose time has come. We play an important role in Siemens' digitalization and sustainability ambitions. Since last Capital Market Day, we have streamlined and improved the business, not just delivering on our commitments, but even ramping them up. We do what we say with a particular focus on improving profitability. We are ready.
Our team is highly motivated and has managed the pandemic well. We are all proud of the positive contribution we can make to society and in communities. We are a strong leadership team, 12 personalities, five different nationalities, one common goal, to be the leader in Smart Infrastructure. We are committed to meet our financial goals. After spending more than half of my career in the infrastructure business around the world, I can tell you there has never been a more exciting time for Siemens Smart Infrastructure. We create environments that care. Thank you for your time and attention. It is now my great pleasure to hand over to Michael Peter, CEO of Siemens Mobility, to share the perspective of the mobility business.
Welcome, ladies and gentlemen, to the fascinating world of mobility. My name is Michael Peter, and I am the CEO of Siemens Mobility.
I have been in this industry for almost 30 years, around 10 years in sales and project management on the rolling stock side, as well as another 10 years in the signaling business. I had the fortune to get to know our business from all angles and from various management levels. Let me tell you, these are truly exciting times for our industry. The market is pushing us to new solutions needed for CO2-free mobility, leading to high-value growth possibilities that I've never seen before in this industry. We all know that for the past decades, the rail industry has been rather slow in innovating, mainly due to the extremely high safety requirements and harsh environmental conditions in which we operate.
It now really takes the best of the industry to change that. It takes the deep domain know-how paired with automation know-how and technology know-how in a way that only Siemens has it. Before I get into the technology game that we are playing and we are leading at Siemens, let me first talk a bit about our market.
Obviously, the market was heavily impacted by COVID-19 in the last year, which affects us into the three years average market that we show here in the background. Several projects were delayed, and this was most notable in the urban area. However, I'm glad to say that the need for clean and sustainable transportation is much stronger than the COVID impact. Urbanization is still accelerating. Cities are predicted to grow by 2.5 billion people in the next 30 years only. The only way to enable these large masses of people to commute in a sustainable manner is with more rail transportation. We can already see that the stimulus packages around the whole world will be used over proportionally to invest in rail systems.
Stimulus money in the past has always been used and spent on infrastructure, but this time it must also be spent on systems to meet the climate targets. Large programs are on the way in Europe, in the U.S., and in several individual countries. For example, Digital Railways in Germany, the DSD program. Our prediction is that in the next few years, the market will grow back to levels even higher than what we had thought before COVID. There's one thing about this market that I consider even more important than the mere growth of it. That makes this market really a Siemens market, supporting our profitable growth ambitions. That's digitalization. Digitalization is transforming this market from within. That's really important as the market therefore supports our strategy to go for technology leadership. This growth is driven by two important trends.
Firstly, increased competition on the rail. Much of the growth of rolling stock will be happening through concessions, for example, in the regional markets. That means that our customers bidding for concession do not look for the cheapest rolling stock. They are looking for the most intelligent solution to maximize their own business case, and that means over the life cycle of the 30-year concession, including energy consumption. Secondly, on the infrastructure side, our customers, often supported by governments, are increasingly moving to country-wide bids, like in Belgium, like in Norway, like in Austria in the past, and currently, such bids are going on in the Netherlands, for example. Now, why is that? Because you can really only optimize the network if you have a consistent digital system for the complete network.
Again, our ambition to reinvent transportation with technology, thereby leveraging our core portfolio with digitalization and investments of the past years, is paying off now. Our IoT and cloud technology on infrastructure side has significant advantages here over the traditional technology of our competitors, and we are uniquely positioned to combine the real and the digital world on a country-wide rollout program in the rail market. Technology leadership is by far the largest lever to gain market share and to lead the competition when it comes to profitability because it offers jumps in efficiency for all customers. This is what our customers, Karl-Heinz, our CFO, and me want to show to you in today's session. Let me start by explaining what this means for rolling stock.
Over the last year, we have developed clear market leadership with outstanding market shares with our Vectron platform, which is our locomotive, with our Velaro high-speed trains being delivered, for example, to Deutsche Bahn and others. Most recently, with the Mireo, we are targeting the same for the commuter rail. As a matter of fact, you just saw me arriving in one of them, really an excellent train. I had a great ride. For rolling stock, technology leadership means developing the best platforms. A rolling stock platform means the technology core of the train, such as engine, bogies, transmission systems, can be used in several train variations, and the other parts can be individualized. When you develop a rolling stock platform, you have three advantages.
Firstly, you can use your complete digitalization know-how and put a lot of brains and R&D into the platform because you will use the platform for many, many projects. For example, the Mireo is an ultra-lightweight design and needs much less energy than other trains, up to 25% less consumption than previous models. It takes new designs and new simulation tools to design trains like that. We can put a lot of connectivity and intelligence also in the design at the same time. With this, we combine the real and the digital world. Secondly, platforms must allow optionalities so that in the end you can sell the same train to many different customers with varying needs. Again, for example, the Mireo platform allows for different propulsion options.
It can be purchased as a normal train set by the regular overhead line, but it also can come with a battery version. Now we are also adding a hydrogen generator to charge the battery to have the third possible propulsion system on board. It's extremely important to be able to gain advantages of scale in our industry, even if individual order sizes might be one or a few trains. Scale in our industry is not really about the total number of trains a company can sell. While it's about having a platform to serve small or large orders of trains. This really drives efficiency and scale. The quality of the platform decides this game. Thirdly, a well-thought-through platform that takes many years to develop allows still very speedy inclusion of fast-track innovations on top of the platform.
For instance, when Deutsche Bahn ordered new high-speed trains, fast-track just last year, we were able to still offer all innovations that DB wanted on top of the platform. Changes in interior, new Wi-Fi in the train, new passenger information systems, new specially coated windows to allow better 4G penetration to maintain connection 26 in the train. By the way, in the end, the platform also guarantees reliable project execution. That is a key ingredient to reduce project hits, and it really is one of the secrets of our Siemens Mobility performance in the last years. In addition to rolling stock, intelligent infrastructure is key. On the rail infrastructure side, the role that technology plays might even be larger than on the rolling stock side. Infrastructure providers cannot just put more rails into the countries, let alone the bottlenecks in the cities.
The task is very clear for us, increase the throughput with technology. Countrywide optimization of networks is the solution. Several years ago, we started to develop the technology for that. We had very simple two slogans for it. Number one, everything is IoT. We as humans know IoT like no one else in the industry because, for example, our colleagues in Digital Industries have been pioneering IoT in automation for many years. For us with Mobility, it means that all field equipment must be connected and remotely controlled. This is exactly what we are rolling out in the complete country of Norway for the very first time in the world. Number two, move the logic to the cloud. This is the interlocking but also the European train control signaling system.
This is what we have pioneered the first time in the world with an interlocking that recently went live in Austria. That is exactly what we will be doing for the complete ETCS signaling system in Austria, where we just won an order for the national rollout program and have committed to move the logic to standard cloud service. While it sounds simple, the safety target for these applications to obtain the operation license is one safety critical incident every 100,000 years. To achieve and guarantee that in the cloud has taken our best engineers years and large R&D investments. We are currently the only ones that can do that in the cloud, and that's a real game changer for our customers. No more special spare parts from the '60s and '70s or managing country operations from over 2,000 interlocking buildings all over the place. No.
All data and software can be on a standard over-the-shelf server or in the cloud. That means consistent operation of the complete network from 1 single location. That means maintenance will be reduced by 30%, and throughput can likewise be increased by 30% in combination with other technology advances we have achieved. Of course, this is also the basis to have driverless operations in the future on top of this technology. All of this is what Roland referred to as grow the core. We are growing, and actually we're transforming our core business through digitalization. Our real strength in doing that in signaling is that with a global market share of 25%, we are undisputed market leader. We can develop this technology in our home markets and then roll them out all over the world.
Needless to say that rolling stock platforms and interlockings in the cloud will not only drastically improve operations but also revolutionize the service. Our trains are today already intelligent computers on wheels, sending operational data all the time while they're on the track. Our infrastructure has the data of all field equipment in the whole country available in just one location. For example, with the Railigent application suite, it's very easy now to compare the behavior of all doors of many trains in operation or of all point machines in a whole country and to identify anomalies in one particular door or in one specific point machine. In this way, we can focus on predictive maintenance, only do maintenance when we know there will be problems upcoming.
At the end, that results in reduced maintenance and reduced life cycle costs, but at the same time into higher availability. All of this can be brought together very nicely in turnkey projects, which is the one portfolio element of our business units that I have not mentioned yet. We have a very strong record in complex large projects, for example, Bangkok or Riyadh. Ladies and gentlemen, this brings us to our first deep dive about what it means to be technology leader in this exciting market. As I mentioned, late last year, we put the first interlocking in the cloud into service in Austria. It's the first and the only one in the world, and I've talked about how it replaces relay interlockings or electronic interlockings and enables us to control a complete network remotely with only one data center.
Customer will give you details about what that means for ÖBB, the Austrian Federal Railways. Just 1 comparison from my side, so you understand my personal excitement about the possibilities that this technology shift will offer to us. If you compare this to the telecom industry, the relay interlockings that still make up over 50% of installed base in every European country today would be comparable to telephone with a rotating disk that we used in the '70s, completely analog. Now in 1 gigantic step, we go to voice over IP, like on your smartphone. This is exactly what the interlocking in the cloud is, computing in the cloud and communication over IP to the fleet devices somewhere in the country.
The Austrian main grid is approximately 3,500 km long. We operate this main grid with more than 600 interlocking stations. It's a lot to do to change this old technology into the new digital world. We need here, as a critical infrastructure, a powerful partner, and Siemens is a powerful partner. As we've seen, we have a big tender about ETCS, the European Train Control System. Siemens won this tender. We go with Siemens in our digital future. We assume that this new technology reduces our CapEx and OpEx because we can centralize the computing units into the cloud. We can reduce building for interlockings and so on. It's for us the possibilities to reinvest in a very quick way from the old technologies to new digital interlocking technology.
Our second example will capitalize on the connectivity of our platform trains and the interlockings. For several years now, we have invested heavily in creating value out of the data that these systems generate. I mentioned before the possibility to predict problems in equipment before these anomalies lead to a failure. Today, we have over 10 research centers distributed around the whole entire world, which are specialized in data analytics and artificial intelligence and helps develop such algorithms. Through our digital asset management solutions for rail systems, our customers can achieve the optimum balance between performance, cost, and risk to ensure profitability and competitiveness with always 100% system availability. We have been heavily working to convert this knowhow into a means to provide standardized services that scale.
With Railigent inside, all our trains and infrastructure solutions shall come with built-in connectivity and services that can be switched on if the customer wishes so. Let's see what our customer has to say.
Railigent gathers and analyzes data from our train fleet and helps us make smart decisions for the operation of the train and for Siemens as a maintainer. These Class 700 trains generate 9 million data points across the fleet each week. This helps show exactly how the trains are running and makes it easier to diagnose and fix faults. All this information helps to improve the availability of our service, reducing delays and improving, therefore, passenger satisfaction. We have a great partnership with Siemens Mobility and have had for years, and the digital technology is a real game changer. The Railigent platform really supports us in delivering reliability and reducing costs. Maintenance is data-driven, with 30% of all work orders generated automatically by the train directly scheduling into the Siemens maintenance management systems, so making the maintenance really smart in terms of efficiency and cost.
The strong statements from our customers underline our strategy of leadership through technology and digitalization. Let's look at how all of this translate into business figures. I would like to hand over to our Siemens Mobility CFO, Karl Blaim.
Thanks, Michael. Hi, everybody. Exciting things happen at Siemens Mobility. I am the CFO of the mobility business since now nearly seven years, and I have had the pleasure to serve as CFO of both the rolling stock and the infrastructure business for additional seven years. It has been quite a journey these years, but we have developed mobility into something really special.
Through all the things Michael just showed, but also by the means of rigid execution and commercial prudence. I would like to guide you through what I stand for. First and foremost, growth must be value-creating with a sustainable margin expansion, giving enough headroom for investments and stringent capital allocation to sustain our technology leadership position. Second, every order is a commitment towards our customers to deliver in time, in quality, and in budget. Therefore, risk and opportunity management are key. Third, we have managed to be ROCE accretive to Siemens due to our low asset intensity, and this will remain also in the future. The basis for all of this is tools, processes, but most and foremost, people and an open culture. I have had the opportunity to build up, educate and train, and I truly believe this, the best team of commercial project and line managers.
Day by day, they go beyond the pure number crunching, creating value for the company. This has been the basis for our resilient performance in project business. It's ultimately reflected in a proven track record throughout 29 quarters above industry peer levels. You do know our numbers by heart. Siemens Mobility is a long cycle business. Based on the large backlog at hand, we typically know what we have to do. The backlog gives us visibility and resilience. It's however, also rather a marathon than a sprint. Therefore, it is of importance to judge the business performance not on a single quarter only, but rather on a long-term view. The important things. First, we have been consistently growing the business with a CAGR of 4% and above the market.
More importantly so, we therein have increased our share of recurring revenues from services from 13%-15%, a 9% CAGR of our service business. We have reached an order backlog of more than $32 billion. This includes a service order backlog of $10.5 billion. Our book to bill was constantly above 1 for our total orders. We have proven our project execution capability that we can deliver above industry profitability over the last 29 quarters, quarter by quarter, and we haven't compromised on innovation. We continue to be technology leader with significant R&D spending. In addition, we have managed our cash flows and achieved an accumulated cash conversion rate of better than 1 minus growth. We all know the ultimate yardstick though is competition, and we don't have to be shy when it comes to comparing ourselves with competition.
Even in difficult times, such as the global pandemic year 2020, we delivered robust and resilient results. Compared to the combination of two major competitors and a big Chinese competitor, surely we do have less backlog, but size doesn't do the trick. We have been growing faster in terms of revenue. Matter of fact, we have been the only one growing in the pandemic. We have been delivering the best EBITDA margins and have been delivering on our promises on cash flow. How did we do that? Project management excellence. Just as an example, we have developed an empirical database early warning system, allowing us to act early on if problems might arise. This has helped to keep our non-conformance costs on a very low level and gives us great visibility into ongoing project execution. We have a quite efficient factory footprint, lesser but larger factories.
As outlined by Michael, we have been proactively managing our customers' transition from CapEx to a life cycle OpEx-driven industry through digitalization. How do we stay best in class? Let me tell you about our Competitive Growth Program. We thereby will rely on three levers, growth and scale, business mix and innovation, and operational excellence. The Competitive Growth Program is a logical extension of our past successful development. It is all about developing the center of gravity of our portfolio into areas of higher profitability and more recurring revenue streams like service. Let me give you some examples for the different levers. First, growth and scale. As being said, there is a lot of motion in the market based on the available stimulus packages. Rail is that perfect spot which combines economic stimulus and CO₂ savings at the same time.
We will foster profitable growth by diligent execution of our large infrastructure projects. We are clearly targeting to increase our base for resilient revenue as well. We will further increase our service order backlog, which has been at EUR 10.5 billion in fiscal 2020. Our plan is to grow this number with a CAGR of more than 8% until 2025. Second, business mix and innovation. Rolling stock platforms and, for example, interlockings in the cloud will not only drastically improve our customers' operation, but also de-risk project execution and drive resilient margin expansion. We have invested early in these fields and are already the number one signaling company. With the program levers in this category, we are setting the right priorities in resource and capital allocation. Third, operational excellence. We have been already increasing our rolling stock manufacturing footprint in Eastern Europe during the last three years significantly.
We will continue to do so and even accelerate our ramp-up of engineering centers in India and Eastern Europe. We plan to add 2,000 engineers in low-cost countries until 2025. These measures contribute in addition to our 3% base productivity. As an interim readout, we expect to grow at a CAGR of 5%-8% until 2023, exceeding the EUR 10 billion revenue threshold and a profit margin of more than 11%. With those levers in place, we shape and prepare our future. Michael, why don't you come back to the growth and scale lever and fill the audience in on what we do in the ESG area? Our market is driven by the need to have clean transportation available for everyone. We, Siemens Mobility, are ESG and a very strong contributor to the DEGREE framework presented early on by Judith. Our portfolio supports decarbonization and achieving climate targets.
Today, our trains can provide 100% CO2-free transportation at a very high capacity and little space used per person transported. Where lines are not electrified yet, in the future, we want to have the same efficiency with alternative propulsion systems. We have developed platforms that today then also allow for battery-driven or hydrogen-driven trains. We are leading the industry already today with battery technology. For hydrogen, we have decided to skip the first generation and will put directly the second generation train on the tracks in 2022. Also taking the lead here with a concept that is far superior to other hydrogen trains on the market. Our first hydrogen train will be right away a modern and fully fledged mainline train with all the acceleration needed to run even in a mixed operation.
Huge reach of 800 kilometers, something that no other train on the market today can promise. I've talked a lot about why we have chosen to go for unrivaled technology leadership. Karl has presented what that means for our business numbers, and also how we control our strategy and translate it into strict measures so that the execution of our strategy, our growth plans, and our projects will lead to the business numbers. Together, Karl and I are firmly convinced of our commitments to deliver industry-leading results, and Karl will guide you one more time to our commitments. Karl, over to you. Thanks, Michael. As in the financial framework, all our commitments are over the cycle. Based on the market dynamics and our positioning, we plan to grow faster than the market with a CAGR of 5%-8%. Our special focus is on resilient business development.
As already said, we plan to grow our service backlog with a CAGR of more than 8%. Service backlog today already accounts for one-third of our overall backlog of EUR 32 billion. By growing our service backlog, we will further increase our basis for future resilient revenue streams. At our last Capital Market Day, we have already increased our target margin band to 9%-12% profit. Based on the positive developments we have described, we do increase our guidance on the target margin band once again to 10%-13%. Way better than the competition. All of that with a strict focus on cash and financial resources used. This is ticket infrastructure business, which is subjected to volatility over the quarters. However, over the cycle, we commit to a cash conversion rate of one minus growth.
Last but not least, a business can only be as great as the teams that make all of this possible. If you ask any of our almost 40,000 employees why they joined Siemens Mobility in the first place, it's because they wanted to build the best trains. They wanted to build the most intelligent infrastructure. They want to transform mobility ecosystems through digitalization. This is what they take pride in, and it's their passion for mobility that drives our success. Thank you very much.
Thank you very much, Michael and Karl and Matthias and Axel for your engaging presentations. We will move directly to Q&A. Since we have both leadership teams here on stage with us, it would greatly help us if you could make clear whether you direct your question to the Smart Infrastructure team or to the Mobility team. Please limit yourselves to two questions per analyst. With that, let's get started. The first question comes from Ben Uglow from Morgan Stanley. Ben, your line is open. Please go ahead.
Hello. Thank you for taking the question. It was really on Smart Infrastructure and maybe for Axel, but whomever. I just want to understand that the raise in the margin target and what you're actually seeing that's getting there, what is actually driving that change? If I look at the businesses between electrification, 27%, buildings, 47%, and electrical products, 26%, what part of the portfolio is mainly responsible for that higher margin target, please?
Sure. Thank you for the question, Ben. When we started Smart Infrastructure, we were looking at our business, we figured out each of our businesses trailing the best performing competitor in its category. We said, okay, look, the target is you have to narrow the gap to your best performing competitor. That was setting the expectation, from there on, we were saying, okay, deliver us a plan on how you close the gap by latest 2025. When we started this, everyone was trailing each of our businesses. Looking at this today, we're seeing the progress being made in all of the business. Also seeing the first ones having almost closed the gap to competition. Having said this, we will have to continue to grow above the market, which we have clearly as a target.
We will have to have a competitive portfolio through innovation, and we have spent a lot of money in the past, renewing the portfolio to be competitive. A big piece of this is getting the cost out and optimizing the business mix, what we say is our competitiveness program. If I stick for a second on the business mix, business mix for us is weeding out the portfolio when it comes to low performance or not really accretive to the business. The second part is also driving those areas of the business which have a high margin quality. That's why we look towards the service business and why we also look about the product business, because product business itself, with innovation, with the economy of scale, with the cost measures, that's the recipe basically to narrow the gap to competition.
As I said, where we are today is we're encouraged by the successes we've seen so far, but we also do know by far we are not there. If I compare Smart Infrastructure with Digital Industries, they are there, we have still to get there, but that's why we say, okay, it's all about the execution of the plans we have laid out. I think we have a track record demonstrated so far, and our clear target is we will deliver as we have laid it out.
Thank you. Obviously, I can understand that there has been some progression, but we're still talking about 10%-11%, hopefully, a little bit higher this year, type margins. When I benchmark those components versus competitors, we're certainly more in the mid-teens range. I understand we're going to get more growth, I understand mix and all these things. Is there any one area where you could really concentrate to lever this margin a little bit higher? The reason, with all due respect, I'm asking this is we have been having the conversation now for 15 plus years. What is it that could take this higher? Is there one business or one activity or one divestment, one thing that would be beyond we're benchmarking versus better competitors?
Our biggest lever closing this gap is our product businesses. This is where we have to focus. They already started with the biggest gap that we will see the fastest momentum building.
Okay. Thank you very much.
Thank you, Ben. The next question comes from Daniela Costa from Goldman Sachs. Daniela, please go ahead. Your line is open.
Hi. Good afternoon. Hope you can hear me. Thanks for taking my questions. I have two. I will start with Smart Infrastructure. You've mentioned that a portfolio review of some of the lower margin business is mostly complete. I know there's still EUR 500 million of potential for divestment. Can you talk through now that you're mostly done with that, give us a little bit of color in the three main sub areas, where do you see your market position and whether there are any pockets that you think going forward you might actually want to strengthen maybe with more inorganic investments? That's the Smart Infrastructure question. Maybe I'll pause here and I ask the Mobility one afterwards.
Yeah. Thank you, Daniela, for the question, which is pretty broad, and it relates to also the topics that I've shown in the video. If you look at the three areas that how we cut the market and cut our business, electrification, buildings, and electric-filled products, and we shared some of our success factors there and also the KPIs and also where we think we have a leading position. For example, in Smart Infrastructure, also on the grid control with a huge installed base, also especially on the substation automation protection business, as well as in the GIS and being the first of also offering the blue GIS, I would call this a leading position in technology, but also in the market position overall. On buildings
I would say we are a leading company in smart buildings here and on the top 2 for the overall building market, where we serve products, solutions, services, and now even more digital services. Having not only the resilient service business within that business mainly, also the digital revenue is related very much to digital services plus software. Enabling us also to build on our installed base and our legacy and the strong customer intimacy that we have for the future success in building digital and smart building business. Axel was already talking about electrical products, which is really the foundation, which goes in all of our markets, all of our customers, a strong growth rate and renewed portfolio, where we are on a good track to improve our market position as well as the profitability based on an innovative portfolio.
A strong focus in the business, as well as a growth strategy across all our markets. You have seen this also in the recent performance of our business, and especially also in the product business in the first half of 2021.
Thank you very much.
Of course, the second part of the question was related to M&A. Of course, for all of our business, we are screening the markets also. That was not limited to M&A, it's also about partnering with other companies and also within the company, leveraging the technology base that we have in Siemens. Also the strong hold in the digital twin story, what Cedrik was showing today, again, for Digital Industries. How we can build on that and leverage also the strengths and the benefits within the company, partnering with others within the industry, which is really moving towards digital and sustainability, as I was talking about before, and really build on this. Of course, also externally, we are open for acquisitions in dedicated markets to drive either digital business or sustainable business or strengthening the core.
Thank you for that. My question on mobility relates to, as you've mentioned, you have higher margins than other peers in the space. You also have a different structure. I guess you're part of a broader group, versus a lot of the others being pure plays. Can you talk a little bit about the benefits? How much do you think of that higher profitability might be being able to tap in other parts and other investments they are doing elsewhere in the business? What's the advantage of not being a pure play, basically? Thank you.
Maybe I start with probably trying to explain why we are where we are. You have seen in our presentation, basically our strategy. We do believe that we have a quite efficient manufacturing footprint. We have fewer but larger factories, and that's actually where the productivity hits the road. As Michael has been showing, we are investing heavily in innovation and digitalization for a certain purpose, and the purpose is also to optimize the life cycle costs. The customer is also, you could see in the statements of our customer, is exactly transitioning into that arena. We do have invested also in platforms. Platforms meaning you have retiring risks already early enough and therefore you have a much better handle around your project execution.
Last but not least, we are part of Siemens, and Siemens does give us a lot of benefits, being it the access to core technologies or being it a strong balance sheet which we can leverage.
Thank you. Thank you, Daniela. The next question comes from Phil Buller from Berenberg. Please go ahead, Phil. Your line is open.
Yes. Hi, good afternoon. Thanks for taking my questions. I have a couple on the SI business, please. I guess the first is an extension of the other questions, really on the margin gap, and I don't wish to labor the point too much. Is there anything you see that is still unaddressed and low-hanging fruit? I'm thinking particularly in terms of your own pricing strategy. One of the things that we've seen from one of your higher margin competitors was a strategic decision to be much more selective on bidding and tendering, which has weighed on their growth for a few years in exchange for structurally higher margins. Is that something that you are considering and have factored into the higher growth guide?
Also, can you just talk a little bit on the gaps in the portfolio in SI, perhaps on the BMS side or low voltage products? Is M&A something you'd hope would be accretive to margin going forward? Thanks.
Yeah. I think it's actually about three topics. One was perhaps the low-hanging fruits in the portfolio. Perhaps Axel, you want to address also on this one and where we can improve the first. I take the one on portfolio and also where you see gaps and again, the M&A question. I think I answered the M&A part already before, that this is an option. Where we are focusing on is, of course, we have renewed our entire EP portfolio, electrical product, or 75% of it in the last five years. Really being competitive now and bringing this into the market. We have also for the huge growth market I was talking about before on e-cars charging infrastructure, an almost complete portfolio now put together in the last two years, since we started and put this together.
It's now ready, and we are really seeing huge growth rates there. Of course, there's one or the other gap in that portfolio, which we are still closing organically. Combining this and as you combine the digital and the real world, the portfolio there also with our software suites. That is, of course, for the grid edge software, but also the smart building software, connecting the automation world of buildings with the automation world of grids. Also the e-car charging infrastructure as a significant contributor to that into this portfolio. These are areas of investments where we are focusing on. Definitely on software, digital platforms, and the like. Of course, also open for acquisition and partnering, as I said before. On strategic decisions on where we focus and, of course, we do solutions to enable service.
We do solutions to pull through products. They are all closely interlinked, and that gives us also some, as what we call, a resilient portfolio mix to when we have short cycle business booming up as we see it now, while the solutions business is still a little bit lagging from the pandemic. Now we see orders coming in there again, and then service is balancing this out over the time. That's what we call a resilient portfolio and where we are focusing and, of course, always making strategic decisions on where we want to invest in and where we are bidding in also in terms of projects. Axel, perhaps you want to talk about some low-hanging fruits?
Sure. Yeah, maybe quickly to the low-hanging fruits. I would say the really low-hanging fruits we have already cracked. The parties here we have identified and have started to execute on measures while it takes some time to really see the benefits. We are continuing on what we have started and the impact will come, which is mostly on the portfolio side. What we have done also, we became much more stringent when it comes to where do I spend the money for. We have stopped certain investments which had started and which basically started to be derailed and relocating the money to what Matthias was describing.
Lastly is also what you can actively manage always very fast is, okay, how much do I invest in a solutions business, which traditionally has lower-margin businesses, versus accelerating other businesses like in the area of service or in the product part. This is what we do on a day-to-day basis, and I think it shows early fruits, but again, it's still a way to go.
Actually.
Thank you very much. We try to conclude the session at quarter past two. What I'm hoping to do, the next person in line is Alexander Virgo from Bank of America. Alex, if you could limit yourself to one question so we have also time for one more question from Andreas Willi from JP Morgan, that would be fantastic. Thank you. With that, Alex, please go ahead. Your line is open.
Sure. Thanks, Eva. It's an FI question, and I wonder whether you could clarify how the digital revenue, EUR 700 million, splits across the verticals, i.e., the differences between portfolio and customer mix and just where it appears in the business mix. Is there a balance between just some solutions in software and services, so you have some digital services and some software? I'm just looking for a little bit of color on that. Thank you.
Digital revenue, as we say also in our markets, electrification, electrical products, and buildings, and we say grid edge and digitalization are growth fields across those markets. This is also how we structured now also our reports here, that we say the digital revenue goes across all of the business. We have, of course, digital business, which include digital services, which also include the software that we are selling and like our building management suites and also the metadata management, the grid control software. That is all included there in what we call digital revenue, but also the cloud-based and analytics-based digital services that we, for example, apply especially, mainly in buildings.
It's a combination which goes across all of the business, and it's also important because we're also leveraging common technology, as well as especially if we talk about the building, and I was reading also the report from you about the Bank of America from the smart building business, which is really, and also aligned with how we see this, really increasing and also helping them along design, build, and manage and operate to give us more growth fields also for our digital revenue. That's exactly where we want to double the digital revenue to EUR 1.5 billion, as we said.
Thank you very much. Thanks for the shout.
Thank you, Alex. The last question comes from Andreas Willi from JP Morgan. Andreas, please go ahead. Your line is open.
Thank you very much for fitting me in. I hope you can hear me. I can't see myself, but hopefully, you can hear me.
Yeah, we can hear you.
On the portfolio, in terms of growth businesses, obviously, one of your competitors has a very strong data center business. You're not playing in the core of that market in terms of UPS, what's data centers for your business and what's your strategy there? Maybe as an indication of size. The same for EV charging, where ABB has announced they're going to list their business. You've heard you're as a market leader. ABB has about said they had about EUR 300 million revenues. How do you compare against that? Thank you very much.
Thank you, Andreas, for the question. Let me really quick on data centers, I talked a lot about data centers two years ago, and that is of course important. It's one of the most important verticals for us. We continue to have a 20% growth rate there. We are considering ourself a strong number two in the data center market and with, as I said, strong double-digit growth rates. It goes across the business. There's also an area where not only fire safety automation, but also then low and medium voltage and the software play together very well. That's a real strong story for the SI overall portfolio and then also leading to additional growth, which we had 20% over the last two years per year.
On the e-car charging, I will not comment in detail, of course, what the other partners in the markets do with their business. Of course, it's a huge growth opportunity, as I also said in the video, with 30%+ growth rates, and that is where we are focusing. We have invested in our portfolio. Now it's about sales focus and continued investment. We definitely run this different than like we run our fire business, for example, in our business. With a clear focus, dedicated teams, a strong focus on this important market, and also combine it with digital offerings and software to make a difference.
Thank you.
Thank you very much. Thank you very much to everyone, to all of your excellent questions. I am really sorry we have to wrap up at this point. We will be picking out some of them and others that you sent to us online in our fireside chat, which we will commence in 10 minutes. Now we are taking a quick break, change our setting, and we will be back in 10 minutes. Thank you.
Thank you.
Welcome back to the final part of the CMD, the fireside chat with the Siemens Management Board. What we've been trying to do is to channel all the questions that you had throughout the day and that may not have been completely answered into this last session. I will kick it right off with a question to Roland Busch. People want to know, in connection with the adjacent market opportunities of EUR 120 billion that you highlighted in your speech, which markets are these, and how do you want to unlock them, and what role does M&A play in unlocking these markets?
Well, we knew that this EUR 120 billion create a lot of attention, particularly because they come with higher growth, but also very good profitability. We want to address these markets in two ways, organically and inorganically. Here I give you an idea how we do that inorganically. Supplyframe was an acquisition which opened up really the market for digital supply chain platforms and marketplaces, which is now stepping into that and, as Cedric explained, has the opportunity for us to really leverage it and expand it to other markets, too. Verve is another example with more stronger acquisition, in order to really open up therapy market for cancer. This is one. We also develop organically in these markets, there are two others which I'd like to mention, which is the IoT transformation market, IoT transformation services, also digital transformation services.
There we are investing organically, but we're also looking into that profit pool because it's very interesting. It is exactly playing our strengths, combining the real and digital world, integrating it and providing superior services to our customers. Therefore, it's a blend of organic and inorganic moves.
Maybe as a follow-up question on that one, as you pointed out, these are highly attractive markets, and they're growing fast. How exactly will you establish value-creating M&A?
Yeah. I would like to repeat what I said before because I think it's very important. Number one is we really want to be very stringent regarding capital allocation when it comes to acquisitions. Again, our six imperatives, it has to be high growth market with good profit pools. It has to belong to Siemens, so leveraging our strengths. It has to come with synergies, but also with innovation, preferably disruptive innovation, any kind of new things which we eventually cannot or don't want to develop organically. Last but not least, a new element, it has to support our sustainability program. You also look into the bottom line. ROTCE has to be larger than the WACC. At the same time, we look for earnings per share pre PPA, which is accretive after two years.
We also focus on the integration, which is a very important element. Not only the technical integration, but also the culture aspects, and that we are restricted following on the cost as a top-line synergies or bottom-line synergies. All in all, we like to really follow up on the success which we had so far on both on acquisitions, where we really believe this is the right thing to do, and we have a very good success story here. We would like to continue that.
Thank you very much. Well, switching gears a little bit, Judith. We get a lot of positive feedback on the DEGREE framework, but there's a question around what do you actually mean by saying sustainability equals business?
Very happy to talk about that. We think at Siemens that with our technology and innovation, we're actually uniquely positioned to help our customers achieve their sustainability goals. Whilst we're still committed, obviously, to decarbonize in terms of our own operations and to do what's right in the supply chain, we think that it's actually our portfolio that can make the biggest difference in terms of sustainability going forward. We've been a technology leader in fields like decarbonization, helping with energy efficiency, and driving resource efficiency. If you think about just what digitalization can do in terms of decarbonizing industrial operations, mobility, buildings, we have solutions to offer to our customers. Take Digital Industries. The digital twin technology is a brilliant example of what we can do across all verticals in the discrete and process industry.
If I take an example from SI, it is also what we have to offer, not only in building technology, but also with our microgrids, because we have clever, intelligent solutions to offer that help with flexibility of grids, but also allows our customers to actually feed in renewable energy while lowering emissions at the same time. Of course, there is the future of mobility. As you have heard from Michael Peter today, what we can do in terms of new propulsion technology, whether that is battery powertrains or even hydrogen going forward. We think we are uniquely positioned, and every investment in our core portfolio is also an investment into sustainability.
Thank you, Judith. I've got another question for Roland. It's a bit general. The question is, what are the synergies between DI, SI, and Mobility?
Let me start. Coming from the customer, it's always good to come from the market from the customer. Definitely, we are leveraging the power of Siemens with our strong regional footprint, established over many years, very strong foothold. We have a joint sales force, in particular if it comes to product and channel business. EUR 1.5 billion of revenue goes via the same channel. This is revenue between SI and DI, which they're contributing. Also, if you talk about vertical markets, special markets like automotive, food and beverage, chemicals, where we work with account management. We have corporate accounts, customer accounts. They're bringing the interesting things together, like take the example of Mercedes, where we have project where we really put the power of Siemens on the street. The customer has to work, as Ola said, also with one partner. It goes beyond that.
We have a couple of go-to-market projects which were launched between our businesses, which put the customer at the center of what we do. Is it about our Siemens sales portal, more and more goes digital? Is it about the automation of sales and marketing our processes? Is it about the incentive scheme which we are aligning on in order to really get our feet on the street really up and running also on cash? Also the digital sales transformation itself, which requires data analytics, having a holistic customer view, having data. We have a very strong backbone of technology. We call it company core technologies, where we are leveraging on. You saw that in the presentations. Is it 5G? Is it cybersecurity? AI. We have 1,000 AI experts which are sitting all around contributing.
Also in open source, where we are leveraging the capabilities amongst the company. Of course, our IoT platform, which has a repository for applications. Our machine learning core works on different verticals, for example. There's a lot of domain know-how which is going into that. We are leveraging this horizontally. Also think about connectivity. We are connecting a lot of assets. We can do that across all businesses. Financial organization, which is providing support for big tickets, think about varying financing, but also small tickets. They are working now with their competence of building new business models. They are supplement to what we do in digitalization in order to really get also on a small ticket financing new business models to our customers.
Thank you very much. Next question goes to Ralf. Ralf, we have a question on the progressive dividend policy. The question is, whether the EUR 3.50 of fiscal year 2020 is the baseline for fiscal year 2021, and what growth rate going forward can achieve.
There was a lot of discussion in place for a couple of weeks. Therefore, we wanted to spell it out ourselves. Yes, progressive dividend payments are going to be our policy on the way forward. As you heard, we intend to be quite demanding in terms of EPS growth and the fact that we have been tailoring our new KPI, EPS before PPA, to the cash concerns and cash opportunities that you may have had. We are very close to our dividend payments with that progressive scheme.
The question is, other companies have experienced customers being reluctant in adopting SaaS. What's your view on this?
Our experience talking to our customers and working on the SaaS environment is really that the customers are ready to adopt SaaS in our market. They will see the value we are delivering. Now we want to give them the choice. We repeated that. We wanted to give them the choice, so we're open. The good news about SaaS is that it's actually a motion which has a low barrier to entry. You can try it out and then see if it works. That's why it's so attractive for SMBs. The art actually is once you have a customer using it, is how do you expand it? What we're doing is we're redefining, we have redefined and we're ready sort of setting out sort of this digital sales motion and expansion motion.
The good news is, Ralf said about the investment we've done on going and getting cloud ready. Within that cost is already integrated not only the technological change, but also the sales motion change. We're ready for the customers. We will show them the value, and I'm very sure we will convince them to try it out and buy more.
Okay, great. There's actually another question on the SaaS transition, which is, does Siemens need to spend more in sales engineers and other teams to address the more fragmented SME market?
It's a bit sort of the answer I gave before, and the good news is Ralf gave you a number, and that number is true. This is within that number which we're spending. We are spending it for delivering the SaaS technology, but also redefining this digital land and expand motion. As such, we are actually ready for the SMB customers to adopt it. Tony said it very nicely. The big advantage is, as an SMB, Ruroc was the example. They can just try it out and then use it. We think that the complexity we're taking away from them, from the IT capability, is what will move them in our direction. It's within our cost, and we're ready, and our sales force is prepared for that.
Excellent. Thank you for that. Roland, the next question is for you again. It's a question on the EUR 5.3 billion from the digital revenues. The question really is, could you give a definition or explain a little bit more what it is?
Right. I can do that. Remember, this is a business we want to grow by 10% over the cycle going forward. Within this EUR 5.3 billion, you'll find EUR 4.1 billion of revenue, which is linked to industrial software, our DI Software. You know that very well. Another EUR half a billion comes from, we call, vertical software or business-specific software. This is, for example, grid software or software which goes into buildings. We have a building suite there, as well as Mobility. The rest comes from IoT services and digital IoT services. Here again, I can mention building service, digital building service, which, if you ask me, we have talked about the levers to close the margin gap. This is another one, because it not only provides additional value to customers, but it also lifts our profitability in this very attractive service business.
It's also digital service, IoT service from Mobility or Digital Industries.
Thank you very much. Matthias, here's a question for you. We have received several comments on how different SI looks and feels in comparison to the CMD in 2019. If you have to sum it up in a few sentences, how would you summarize the progress that SI has made since 2019?
Yeah. First, I would say 2019. We were standing there together, Cedrik. When we formed the new business, coming with different business came together from the energy management, building technologies, parts from industry. We put this together for a purpose. We have made strong progress from my perspective. If I may say, I would say we have become a valuable core business for Siemens with combining these assets and developing this further. We also had delivered on our commitments, continuously improved the performance. How did we do that?
Axel and I, we were talking about this earlier today, with focused innovations on the growth fields of the future, digital services and products, as well as on, of course, above-market growth, which we have delivered over the last many, many quarters, as well as the continuous and consequent implementation of our competitiveness program with all of the levers. We have a clear ambition which is with sustainability at its heart to make it a business or make it part of our business, and also with digitalization as the brains, as I called it before, to make grids more effective, productive, deal with the challenges ahead of them, as well as to make buildings more secure, effective, productive, and efficient, and even smart or autonomous, as you call it.
We are in attractive markets, electrification, buildings, and electrical products, as we talked, and we are ready to enable and accelerate sustainable energy transition as well as sustainable communities. We are ready, and we continue to deliver on our commitments.
Thank you very much. We keep getting some questions live from you. We're taking one that just came in, which is on the ROCE, Ralf. The question is, Siemens has fallen short of the ROCE range over the past five years, and from fiscal Q3 onwards, the integration of Varian will increase the group's capital employed by nearly 20%. Does it still make sense to keep an ROCE target in such a high range if every time you make a mid-size acquisition, it kills the group's returns for a few years?
First of all, thank you for that question, giving me an opportunity to touch on this very relevant matter. Even though I wouldn't consider Varian being a mid-size acquisition, I think your conceptional concerns are very valid. What we said is transformatory transactions like Varian, with an impact for 3, 4, 5, 6 years, which cannot be changed by operational performance. It doesn't make sense to include it in ROCE. Therefore, we took it out to give you a clear and crisp view on how we are doing on an annual basis, which is important for you guys to compare ourselves to peers, but also for us to see where we stand in terms of capital efficiency. That does not mean that we would eliminate other acquisitions that are not of that magnitude.
Assuming that we don't see transformative acquisitions every year, I think this is a very valid and reasonable figure on the way forward. On top of that, of course, you will see all our disclosures also as reported, including all the KPIs that would reflect the full scope, including acquisitions and their impact on capital efficiency.
Thank you very much for clarifying that. We have one final question that came in for Judith. How much do you invest in reskilling your people to be able to reduce the severance to EUR 100 million-EUR 200 million per annum?
Okay. Let me start by severance, or let me split out the two things, because whilst there is a bit of relation, I do think they're two separate things. We're not spending as much going forward on severance because we're not planning to do significant restructuring. That is, I'm sure, an interesting piece of news for you, but it's an even more important message, I think, to our people that there are no big restructurings ahead. Our investment into learning, education, learning training has been high over the last years. Just last year, even if we exclude the Siemens Healthineers, we spend about EUR 250 million on up- and reskilling and the education of our people. That will become even more important as we go forward.
We think it actually makes a lot of business sense already today, but is going to become imperative tomorrow because of two trends in particular. One is, we've talked about digitalization most of today, because technology is changing so fast. The capabilities, the competencies that we need to have at an organizational level, but also at an individual level, at a person level, are going to change far more rapidly. We're talking about shelf life of knowledge being probably no more than 5 years, particularly in tech and IT-relevant functions. That's one thing. The other thing that's happening as well is demographic change. In some countries more than others, to give you a number for Germany, we think that about 6.5 million people out of 41 will leave the workforce in the next 10-15 years, just in this country alone.
Therefore, investing into the people that we have is going to be critically important for us, and we do that in a number of ways. At an organizational level, we've developed a methodology that helps our businesses understand where capabilities are going. For our people, we have a learning platform that only today has already 100,000 digital learning units, which allows us to democratize learning, give more access to more people to learning, and reduce the cost per learning unit. For us, an extremely important message to give to you as investors, but also to our people. Thank you, Judith, for these important insights.
Thanks to all of you for staying with us for the last six hours. We have really enjoyed engaging with you today and explaining our strategy and way forward.
Roland and Ralf will be going on roadshow from tomorrow. We still have opportunity to ask some of your more technical questions that we may not have fully gotten to the bottom of during the course of today. With that, I would like to hand over to Roland for some closing remarks.
It's time to wrap up our Capital Market Day, and thank you, Eva, for managing us so well through not only the day but also the preparation. Great job. Siemens is a focused technology company and we are positioned for accelerated high-value growth. That means comparable annual revenue growth of 5%-7%, together with increased margin bands for our businesses. We will achieve this by addressing highly attractive growth markets, and we will continue to grow substantially above market rates in all addressable markets. They currently amount for around EUR 440 billion. We are also entering adjacent markets, which account to about EUR 120 billion with even higher growth rates and profitability. Things will grow faster because our technologies empower our customers to master their digital transformation and sustainability challenges.
Just one example, by offering our PLM portfolio as cloud-based software as a service, we will make it easier for more and more customers, large and small, to access the latest digital technologies. Sustainability. It is embedded in our business strategy and it drives our businesses. Still we want to do more. Our new DEGREE framework brings our ESG commitment to the next level. I will give you three examples. We will reduce the waste to landfill to 0 by 2030. We will go for a 0 carbon footprint in our supply chain by 2050, and we will strengthen our training and education offerings, as explained by Judith, for our employees. This will also help reduce our severance cost to a range of EUR 100 million-EUR 200 million per year. We will grow because we can combine the real and the digital worlds like no other company can.
Our core business and our digital business reinforce each other in a virtual cycle. We have ambitious growth targets for our digital business. We expect to grow organically at around 10% CAGR, starting from our strong EUR 5.3 billion in 2020. We will accelerate value creation because we have a clear focus on profit, cash, strengthened capital allocation, and execution. Take our move into Software as a Service. While we execute the transition, we will keep our financial target commitments. We are upgrading profit margin levels for Smart Infrastructure and for Mobility. We are adding a cash conversion target on Siemens Group level. We are committed to be a progressive dividend policy payer. Finally, we strive to grow earnings per share by high single-digit percentages year after year. That's what I mean when I speak of high-value growth.
Thank you for staying tuned and for being with us today.
