Good morning, ladies and gentlemen, and welcome to Siemens 2023 fourth quarter conference call. As a reminder, this call is being recorded. Before we begin, I would like to draw your attention to the safe harbor statement on page 2 of the Siemens presentation. This conference call may include forward-looking statements. These statements are based on the company's current expectations and certain assumptions and are therefore subject to certain risks and uncertainties. At this time, I would like to turn the call over to your host today, Ms. Eva Scherer, Head of Investor Relations. Please go ahead, madam.
Good morning, ladies and gentlemen, and welcome to our Q4 conference call. All Q4 documents were released this morning and can be found on our IR website. I'm here today with our President and CEO, Roland Busch, and our CFO, Ralf Thomas, who will review the Q4 and full fiscal 2023 results, followed by the outlook for fiscal 2024. After the presentation, we will have time for Q&A. The call is scheduled for up to 90 minutes. Since there's a lot on the agenda, with that, I hand over to Roland.
Yeah, thank you, Eva. Good morning, everyone, and thank you for joining us to discuss our impressive fourth quarter and full fiscal year 2023 results. Before diving into our record performance and looking forward with confidence, let me highlight how Siemens continuously strengthens the fundamentals to succeed in a volatile, volatile business and geopolitical environment. All our businesses are leveraging secular growth trends driven by automation, digitalization, electrification, and sustainability. We empower our customers in industry, infrastructure, transportation, and healthcare to accelerate their digital and sustainability transformation. Our technology is transforming the everyday for everyone. It is instrumental in solving the most significant challenges of our time, including labor shortages and resilience of value change, as well as climate change.
More than 90% of our business enables customers to achieve a positive sustainability impact, such as less energy consumption and decarbonization, minimizing waste, less use of raw materials and water, or better passenger and patient experiences. We address the specific needs of our customers in their vertical domains and create substantial value for their businesses. We support our customers to stay relevant and competitive in the future. Three years ago, we started executing our strategy as leading technology company to combine the real and the digital worlds. We are well-positioned to create even more impact with higher speed and agility going forward. A major success factor is the scaling of our offerings by providing a repeatable answer to recurring customer problems. We do that by deploying a common cutting-edge technology stack together with our fast-growing ecosystem of partners.
Our open digital business platform, Siemens Xcelerator, is core to achieve this goal, and I will talk about some exciting examples later. This gives us significant opportunities to consistently achieve high-value growth while driving profitability and cash. Looking at the agenda, we reflect on a record fiscal year 2023. We give a confident outlook for 2024 from a position of strength. I am very proud that we delivered on our raised promises in fiscal 2023 and created substantial value for all our stakeholders. We all experienced another year with ongoing geopolitical and macroeconomic turmoil, including wars, fast-paced interest rate hikes to fight inflation, erratic destocking effects, and skilled labor shortages. Many thanks go to Team Siemens worldwide for a tremendous contribution to successfully managing this complex environment and working strongly together with our suppliers, customers, and partners to make a positive impact.
As a technology leader, Siemens captured significant market opportunities and market share. Orders topped EUR 92 billion and were further up by 7% from already very high levels, while revenue grew by a very healthy 11% at the upper end of our guidance. A book-to-bill of 1.19 and record backlog of EUR 111 billion gives us confidence for fiscal 2024. With all-time highs for industrial business profit and margin, we demonstrated again that our strategy as technology company, powered by a strong operating model, is bearing fruit. Our outstanding operational performance, also compared to competition, is most notably confirmed by continuously stellar free cash flow. For the first time ever, we exceeded the EUR 10 billion threshold and topped prior years' level by a stunning 23%.
This almost equals almost 13% cash return on sales, now for four years in a row in double-digit territory. Operational strength is fully reflected in earnings per share pre-PPA and excluding Siemens Energy of EUR 9.93, slightly above the updated guidance range. Basic earnings per share more than doubled over prior year and for the first time crossed the EUR 10 mark. Profit in the industrial business reached a record high of EUR 11.4 billion, growing by 11% compared to prior year, and this translates into a further improved margin level of 15.4%. All three businesses met, or in the case of Mobility, exceeded their revenue guidance with a full, powerful finish. In Q4, Digital Industries grew by 15% on a comparable basis.
This was the third year in a row with double-digit growth, despite a macroeconomic market slowdown through the year. Profit margin reached 22.6%, a record high level, with strong backlog conversion in the automation business, overcompensating effects from the ongoing SaaS transition. But infrastructure grew by 15% and came in at a record profitability level of 15.4% at the upper end of this year's guidance. Very steady and consistent improvement path, which is underscored by an impressive 12 consecutive quarters of year-over-year profitability improvement. And there is more to come. Mobility accelerated revenue growth by achieving 15%, well above the guided level. For the first time, annual order intake exceeded EUR 20 billion, with a book-to-bill around 2, reflecting strong market momentum.
Even more importantly, the team again achieved industry-leading profitability and free cash flow, managing risks and opportunities in a prudent way. Now, let me outline some key operational highlights of the fourth quarter. Our customers continue to invest in digitalization and sustainability. This led to strong organic top-line performance. Book-to-bill reached 1.02 on strong order growth momentum of 26% in Mobility, and clear order growth at Healthineers and Smart Infrastructure. As expected, we saw ongoing normalization of short-cycle automation demand in Digital Industries. Customers and channel partners were further adjusting inventory levels across supply chains and softer demand. This was partially compensated by an extraordinarily high level of large EDA orders, with customers mainly from high-tech industries. From today's perspective, we anticipate that our automation orders have seen the bottom in Q4.
Overall, revenue growth reached 10% on the highest quarterly revenue level ever in all four industrial businesses. All of them showed similar growth rates in the range of 8%-12%. And I'm particularly proud of our Digital Industries software team, achieving revenue growth of 30%, driven by large contract renewals, mainly in EDA. Once again, the Electrification business of Smart Infrastructure showed great competitive strengths, growing by 25% with ongoing momentum in power distribution and Data Centers. What really matters is value creating growth, and we executed strongly. A record quarterly high of EUR 3.4 billion profit in the industrial business, and as an outstanding highlight, more than EUR 4.6 billion of free cash flow all in. Our financials are clear evidence of our sound operating model and consistent execution. Some more facts.
Digital business reached revenue of EUR 7.3 billion in fiscal 2023, and we continue to launch at high speed innovative offerings and drive the expansion of our partner ecosystem. The SaaS transition in Digital Industries is fully on track, delivering annual recurring revenue growth of 15% in Q4. We continue to sharpen our profile by optimizing our portfolio with selected smaller investments and disposals. An important milestone has been the largely completed carve-out of Innomotics on October 1, as planned. Fundamental strengths of our company, combined with focus on shareholder return, is also reflected in our dividend proposal of EUR 4.70. In line with our progressive dividend policy, we plan to increase by EUR 0.45, and Ralf will explain to you in more detail the expansion of our share buyback activities.
Looking ahead into fiscal year 2024, we will stay vigilant and react flexibly on market developments. We will execute on our long-term oriented investment strategy, which is targeted for attractive market opportunities, and will further improve our global footprint for innovation, production, and service. Ultimately, this leads to higher competitiveness and resilience. Our teams are very close to what's happening at our customers and keep a close eye on OpEx spendings. We are confident that we will maintain a net positive economic equation with a constant focus on productivity, while inflation-driven price effects will somewhat fade in fiscal year 2024. From what we see today, and despite an anticipated muted global economic development, we expect further value creation growth in 2024, and Ralf will give you more details. For the record here, for the record, here are our impressive Q4 numbers.
Let me briefly add that revenue growth was regionally broad-based. EMEA was up by 13%, followed by Americas with 11%. Asia, Australia grew by 4%, held back by softness in China. EPS PPA, excluding Siemens Energy investment, came in at EUR 2.64, driven by strong operational performance. Looking into fiscal year 2024, our healthy order backlog is a source of resilience. It stands at a record level of EUR 111 billion. Lead times in short cycle product businesses in Digital Industries and Smart Infrastructure returned to mostly healthy state. Supply chains and manufacturing execution are back to normal. Our customers and distributors continued destocking in all key countries, particularly in China. We assume this backlog consumption to continue in the first half of fiscal year 2024, until inventories are back to normal levels.
Visibility in our systems, solution, and service business is far-reaching into fiscal year 2024. I briefly talked about the importance of mutually beneficial partnerships to scale new technologies and drive growth. A game-changing example is our collaboration with Microsoft, based on our shared vision to boost cross-industry AI adoption. The first application is the Siemens Industrial Copilot, an assistant for human machine collaboration and manufacturing, enhanced and powered by generative AI. It will allow users to rapidly generate, optimize, and debug complex automation code. It will allow users to significantly shorten simulation times, and it will allow users to tackle labor shortages successfully. Because incremental improvements are not sufficient anymore, step changes are required. At the SPS Fair, just a few days ago, the leading automotive supplier, Schaeffler AG, demonstrated how the Siemens Industrial Copilot will drive engineering productivity.
Together with Microsoft, we are already working on numerous AI copilots in other manufacturing industries, such as consumer packaged goods or machine building. In addition, we have the clear ambition to address all industries where Siemens is active. Our partnership with Microsoft can be characterized as a virtuous circle. Accelerated AI adoption will drive green data centers demand, where Siemens is also an important partner for Microsoft to provide critical infrastructure. Siemens accelerators, ecosystem, and marketplace are growing steadily. At the EMO Trade Fair, we introduced, together with DMG MORI, an end-to-end digital machining twin offering, which is now available on the marketplace. Based on our digital native motion control platform, the SINUMERIK ONE, the digital twin includes the controller, the customer-specific DMG MORI machine tool, and the to-be-machined workpiece.
It enables up to 40% faster production ramp-up, while minimizing unproductive machine times by up to 75%. Our Siemens Industrial Edge ecosystem is enhanced with new applications from pneumatics specialist, Festo. This new offering provides customers with more flexibility to build individual IoT solutions easier and faster, to improve maintenance and increase quality. The Siemens Xcelerator, combined with our domain know-how, is essential to scale offerings and drive sustainability. The first great success story, how we accelerated the digital transformation at our customers, comes from the United States. Together with Ford, we co-created a standardized and scalable SIMATIC automation workstation. It combines the OT installations for manufacturing automation with the IT environment functionality, such as central software deployment. By leveraging our Industrial Edge ecosystem, this innovative platform will enable fast and easy development of digital use cases.
The benefits for Ford are simplified and more efficient processes on the shop floor, and much higher flexibility. It will be widely deployed in greenfield and brownfield manufacturing plants at Ford. Our UK team transferred the experience from optimizing power grids to the water industry. Northumbrian Water Group has started to connect more than 1 million smart meters to our SaaS-based meter data management system, Energy IP. With this major rollout, the utility identifies household leaks to help reduce water consumption. The third example comes from the healthcare market. An offering with significant potential is the comprehensive digital twin for smart hospitals. At the recently inaugurated Inselspital Bern, building, planning, and construction data, as well as construction documentation, are being digitally transferred to operations. This has laid the foundation for providing a digital twin in the future and opens new possibilities to optimize processes while supporting efficiency.
And finally, after the successful commissioning of a first route section, Austrian federal rail provider, ÖBB, presented a long-term framework agreement with Siemens Mobility worth EUR 400 million. We will digitalize the country's rail network with the latest technology, which is a crucial cornerstone to doubling network capacity by 2040. All these projects demonstrate how Siemens Accelerator works successfully.... A core strategic lever for value creation is our goal to grow the digital business annually by around 10% by 2025. Fiscal 2023 was another successful step in this direction, achieving around 12% growth to EUR 7.3 billion, despite the ongoing PLM SaaS transition in Digital Industries. And we are confident to continue this strong growth trajectory in fiscal year 2024. While our businesses allocate significant resources to further develop and promote Siemens Accelerator software and digital service portfolio.
I'm very pleased with the continuing progress of transforming main parts of our DI software business towards software as a service. After two years, we are fully on track to achieving our goal. ARR growth reached a very healthy level of 15% over prior year, which we strive to sustain in fiscal year 2024. Cloud ARR share already stands at EUR 1.2 billion, equaling 30% of total ARR, and we expect to reach the 40% target one year ahead of schedule. Around 11,300 customers have signed on to the software as a service business model with a vast share of small and medium enterprises. Among the SaaS customers, 77% are new logos, underpinning our ambition to sustain this, to substantially expand the existing customer base.
The quarterly customer transformation rate remained on a high level with 87%. Looking ahead, we will actively work on managing the skills transition, as well as digitally selling further functionality and applications. Based on our assessment, we have surpassed the trough of the SaaS transformation of our PLM business and a small part of EDA. From here, we will gradually see higher profitable growth contributions. The largest part of EDA, which marks around one-third of digital industry software business, remains term license-based. As indicated in Q3, we recently announced our plans to expand our U.S. footprint. This is the final cornerstone of our EUR 2 billion global investment strategy to boost innovation, growth, and resilience. In Dallas-Fort Worth, we will build a high-tech manufacturing factory for EUR 150 million, fully equipped with Siemens software and automation, to produce critical electrical infrastructure equipment.
The factory will start production in 2024 and is planned to gear up for full capacity in 2025. This investment specifically supports long-term customers in the data center space, where demand is expected to grow by around 10% annually through 2030. We are gaining market share and achieved an extraordinary strong order level of almost EUR 2 billion in fiscal 2023, and we delivered revenue growth of around 25% for the second year in a row. Sales pipeline visibility into fiscal year 2024 is robust, driven by additional AI workloads and co-location demand. A key lever for further success is our strength in innovation. In fiscal year 2023, we invested around EUR 6.2 billion to constantly upgrade and drive the connectivity of our strong hardware base and intensify investment in our software and digital portfolio.
For fiscal year 2024, we plan to maintain R&D intensity at around 8% of revenue, with further growth in absolute terms. It's our clear goal to extend leading technology pushes, positions, and drive sustainability offerings. A great example for both is our blue GIS switching technology. Without fluorinated gases for primary distribution, it helps our customers to drive the sustainable energy transition ahead of EU regulation. In addition, our central technology team is closely collaborating with all businesses to maximize the impact of, once again, investing more than EUR 500 million in the advanced development of 11 core technologies. We see strong progress and mutual benefits in areas like artificial intelligence, advanced manufacturing, cybersecurity, connectivity and edge, integrated circuits, and power electronics or circularity. A further core strategic lever is continuing portfolio optimization.
In fiscal 2023, we announced some complementary technology acquisitions, such as Avery Design Systems in DI software, or Heliox, a specialist in eBus and eTruck fast charging solutions. We will continue this path of bolt-on acquisitions, complying with our six strategic imperatives. At the same time, we executed several smaller divestments, both in the industrial business as well as from our portfolio companies. After having reduced our share in Siemens Energy AG to 25.1% in fiscal 2023, we are working on an accelerated separation from Siemens Energy in India. Yesterday, we announced a set of measures, including our intention to acquire 18% of the shares in the publicly listed company, Siemens Limited India, for EUR 2.1 billion in cash from Siemens Energy. With this, we agreed with Siemens Energy to accelerate the unbundling of the activities currently conducted in the Indian-...
subsidiary of Siemens by way of a demerger. Ultimately, we target a return to a shareholding of 75% in Siemens Limited India in 4 to 5 years from now. Siemens Energy is to become majority shareholder in the then-listed company, Siemens Energy India. These are important steps to simplify the structure and sharpen the focus, and we will continue this path. The new Innomotics brand, as a leading motors and large drive supplier, was successfully launched and is well-perceived by customers and its more than 15,000 employees. Innomotics is performing strongly with good visibility, based on a healthy order backlog. With these attractive prospects, we have decided to start, as next step, further preparations towards the full independence of Innomotics. We will start preparations for a public listing, while diligently evaluating all other options according to the best owner approach.
We will pay particular attention to ensure a future setup which offers sustainable, growth-oriented, and value-creating development. So as you can see, we further shape our leading technology company in many aspects to drive performance. With that, over to you, Ralf. Let us take a closer look at operational performance and our detailed outlook for the fiscal year 2024.
Thank you, Roland, and good morning to everybody. Let me share more about our powerful finish of the fourth quarter and our outlook for fiscal 2024. In Digital Industries, we saw a good close on top line, ahead of market expectations and driven by an extraordinarily strong EDA software business. As expected, we recorded a continued normalization of order patterns in our short-cycle automation businesses across all key countries. As Roland mentioned, end customers and distributors further reduced inventory levels due to back-to-normal delivery times and a rather muted industrial investment sentiment. Orders for DI in total were down by 8%, with a book-to-bill overall at 0.83. The software business achieved record order levels up more than 30% on 13 large wins, primarily in the EDA space, an unprecedented level for us so far.
Order normalization was driven by the discrete automation businesses, while process automation was lower mid-single digits. Therefore, our backlog in Digital Industries further decreased to almost EUR 11.5 billion. Therein, the software backlog amounted to around EUR 5 billion, a number that has grown gradually in line with the progressing SaaS transformation, which increases the share of recurring revenue. The automation backlog stood at EUR 6.3 billion, around EUR 1.8 billion lower compared to the third quarter, largely as expected. While this is still elevated compared to our long-term levels, the development clearly shows that we are on the way towards levels of pre-pandemic order backlog reach. Customer cancellations remained on very low levels. Revenue for DI was significantly up by 11%. Automation revenue rose 6%, driven by process automation, up by 13%, while discrete automation grew by 3%.
Large order wins in software translated into brilliant software revenue growth of 30% to more than EUR 1.6 billion, by far the highest quarterly level we achieved so far. Whereas PLM was up mid-single digits, EDA delivered a fantastic growth of around 75%. Since EDA is a lumpy business, we should look at the full fiscal year growth rate, which reached an impressive 15%. Profit of almost EUR 1.4 billion marked a quarterly record high with an excellent margin of 23.1%, strongly supported by an outstanding EDA software contribution. To reap the productivity gains related to the SaaS transformation, we set up a program to actively manage the required skill transition of our staff, primarily in the US. This was the main driver for a severance program affecting the DI margin by 120 basis points.
In the automation business, we continued to see stringent execution with strong profit conversion, however, with a less favorable mix compared to prior year. Price increases from previous quarters, which materialize now through backlog conversion, plus productivity gains, enabled us to clearly overcompensate cost inflation in the quarter. As a result, we again resolved the economic equation with a net positive in the fourth quarter. Cloud investments in Q4 accounted for 130 basis points of margin impact on Digital Industries, which was also the overall fiscal 2023 impact. We are proud that Digital Industries once again achieved outstanding free cash flow of more than EUR 1.3 billion, close to previous year's high, leading to a strong cash conversion rate of 0.96.
Main driver was the automation business, where we optimized inventory levels, while the software business saw an increase in net working capital due to extraordinary volume growth. For the full fiscal year 2023, Digital Industries generated more than EUR 4.2 billion in free cash flow for the third year in a row, combining very reliable cash contribution with strong double-digit revenue growth. Now let me give you the regional perspective on the top-line automation performance. As mentioned, automation orders saw further broad-based normalization of demands against tough comps of strong growth in the previous two years. As expected, this was most visible in China and in parts of Europe, where we see ongoing destocking, which will continue into the first half of fiscal 2024.... Yet, in China, we see some first signals of stabilization in current trading following a very soft fourth quarter.
Clear level, clear revenue growth in automation was mainly driven by strong backlog execution in Europe, where Germany was up 18%, in Italy, 23%. China was 14% lower on tough comps and fewer fast-turning orders. In the U.S., process automation was up double-digit. Now looking at our key vertical end markets for the next quarters, we expect rather muted growth momentum, driven by effects from further destocking and fading effects from price inflation, as well as softer investment climate due to higher interest rate levels. Our DI teams see this development as transitional and expect an improvement of sentiment beginning in the second half of fiscal 2024, also driven by secular demand trends. On this basis, after 3 years with extraordinary double-digit growth, we expect fiscal 2024 to be transitional in nature before picking up accelerated growth momentum again thereafter.
We will execute targeted investments in vertical specific applications in a careful step-by-step approach to increase customer value and maximize growth. Looking ahead, we anticipate a soft economic development in the first half of 2024, with sluggish industrial demand, especially in China and Germany, as well as ongoing destocking in key countries. We assume improving trends beginning to materialize in the second half of 2024. As expected, revenue contribution from existing backlog will further normalize, hence, the regular short cycle pattern of new fast-turning product orders will gain importance throughout the year on mostly healthy lead times. Please note that as of October 1, the low-voltage motors business was transferred from DI to Innomotics. Comparable key figures are distributed this morning, and all forward-looking statements refer to the new setup of Digital Industries.
For fiscal year 2024, Digital Industries will again deliver a convincing performance with orders stabilizing throughout the year and constant and consistent revenue development on tough comps. Profitability will remain in the upper half of the margin corridor, despite rather flattish top line and targeted investments linked to expected volume pickup. In fiscal 2024, we again expect to outweigh wage and material cost inflation with productivity and trailing pricing effects from order backlog for positive economic equation. From today's perspective, we will start with the first quarter as the slowest quarter in fiscal 2024, followed by a steady improvement thereafter. Therefore, in Q1, we still see orders well below prior year on further destocking and very tough comps for our automation business. We anticipate for DI revenue growth to be in line with the full year guidance of 0% to 3%.
Automation growth is anticipated to be flattish on tough comps. Software is expected to be around prior year level, with clear growth in PLM on successful SaaS transition, compensated by lower EDA revenue on a seasonally lower start after the exceptional accumulation of large deals in the fourth quarter. Beyond first quarter, we expect clear revenue growth acceleration in the software business throughout fiscal 2024. We see the profit margin for the first quarter to be approaching the full fiscal year guidance of 20%-23% from below, compared to a very strong prior year quarter, with a very favorable automation product mix and a very high capacity utilization. On top, we expect substantial headwind from exchange rate effect at current rates of around -100 basis points. For the software business, we expect a seasonally slow start.
Smart Infrastructure, again, delivered like clockwork, a truly outstanding fourth quarter performance across all metrics. The team achieved excellent top-line growth in robust end markets and another proof point for consistent margin expansion trajectory. In total, orders were up 6%, driven most notably by 16% growth in the Electrification business. Orders benefited again from larger wins, primarily from strong demand in the data center business. Buildings was up 6% based on strength in the solution and service business, while electrical products was flattish on pretty tough comps. The order backlog remains at record level of EUR 16.5 billion. Revenue growth was broad-based and reached 12%, clearly ahead of expectations, with the largest contribution from Electrification business up by a remarkable 25%. Electrical products and buildings showed clear growth with 9% and 7% increase, respectively.
Flawless backlog execution led to a margin performance of 14.9%, up by 70 basis points year-over-year. The business benefited from economies of scale and increased capacity utilization on high-level revenue growth, as well as lasting structural improvements from our competitiveness program. Headwinds from cost inflation, mainly wage increases, were overcompensated by productivity and in-time pricing actions. Currency effects had a noticeable negative impact of fifty basis points in the fourth quarter. The SI team very successfully implemented effective measures to reduce operating working capital, in particular, inventories, despite material revenue growth. Free cash flow showed an outstanding finish with an all-time high of more than EUR 1.4 billion, bringing full-year cash conversion to impressive 0.95, well ahead of our target of one minus growth.
Looking at the regional top-line development, we saw robust demand with strong order momentum driven by Europe and the U.S. on large wins in the data center and power distribution vertical. China was up by 2% on easy comps, with bottoming out of domestic demand. Revenue showed strength in all regions besides China, supported by strong backlog execution in Europe, while the U.S. achieved impressive mid-teen % growth rates. The service business delivered 10% growth, led by a double-digit increase in Europe and Asia. We continue to see nominal and real-term growth in our main verticals, fueled by backlog execution. Sustainability is a key business driver in many market segments. Only commercial buildings is expected to show modest growth going forward due to increased interest rate levels. As Roland said before, we see accelerated growth momentum in the data center vertical on higher adoption of AI-based applications.
Expanding grid capacities and making them more intelligent is another resilient growth trend for which we are well positioned, driven by renewables integration and electrification of everything. For the first quarter, we see the comparable revenue growth rate towards the upper end of our full-year growth guidance of 7%-10%, strongly supported by order backlog. We anticipate the operational first quarter margin to be at the prior year's level, within the full-year guidance range of 15% to 17%. Mobility closed the year with another strong quarter on top line. Orders at EUR 3.2 billion, up by 26%, included two large orders from four commuter trains in Germany, totaling EUR 700 million, which drove rolling stock momentum. While infrastructure orders were substantially up on several mid-sized orders and good contribution from base business.
The backlog stands at EUR 45 billion, massively up compared to prior year after extraordinary order intake north of EUR 20 billion throughout fiscal 2023. Therein are almost EUR 13 billion of service business. This lays the foundation for another year with strong revenue growth in fiscal 2024, yet with a higher share of rolling stock business. Our sales funnel continues to look promising for fiscal 2024 for a book-to-bill well above 1 across all business activities. However, expected timing of project awards indicate an order level materially below fiscal 2023 levels. Specifically on the Egypt projects, we are progressing in the project execution of the Green Line extension, with the first Desiro train recently arriving in Egypt. For the Red and Blue line, the contracts are effective, and commencement date of both lines has been contractually agreed upon for the end of calendar year 2023.
The teams are working towards the financial close, which, from today's perspective, is expected earliest, earliest end of calendar year 2024, after which the remaining order of around EUR 5 billion will be booked. Revenue in Q4 was up 10% on broad-based growth, with a strong contribution from large rolling stock projects. Profit margin reached 8%, in line with expectations on a less favorable business mix. Mobility delivered a remarkable free cash flow of almost EUR 600 million in the fourth quarter, amounting to more than EUR 1 billion for fiscal 2023. This led to a cash conversion rate of 1.19 for fiscal 2023, well above the 1x growth target, clearly differentiating Siemens Mobility from competition. Since Mobility is a long cycle project business, this comparison is even more impressive when looking at a long-term time horizon since 2016.
Mobility delivered cumulatively EUR 7 billion in free cash flow, with a cash conversion rate of 1.05, combined with an attractive asset-light business model. Our assumption for revenue growth for the first quarter 2024 is within the corridor of 8% to 11%, which we expect for full fiscal year 2024. First quarter margin is seen towards the lower end of the full-year margin guidance of 8% to 10%. Now, let me keep the perspective on below industrial businesses crisp. All details are in the earnings bridge on page 35 in the appendix. SFS delivered a solid fourth quarter performance with a higher earnings contribution from the debt business on lower expenses for risk provisions. I'm very pleased with the portfolio companies showing a robust profitability as expected. As mentioned, next strategic steps are on the way, while the teams simultaneously execute their full potential plans.
Siemens Energy investment continued to burden the bottom line due to a material at equity loss, as you know. Tax rate came in at 33%. Now, let me briefly give you the perspective on a solid full-year performance of Siemens Financial Services. Return on equity of 16.3% within the target range is a remarkable success, once again supported by the diversified portfolio, prudent risk management, and a strong result from equity business. SFS has successfully supported the industrial businesses with excellent financing, expertise, and deep industry domain know-how. The team is facilitating entry in new markets and ecosystems, as well as developing innovative digital business models. SFS strongly supports sustainability business for the group along the entire technology life cycle. Based on the current expectations, SFS will start with strong results in the first quarter, positively impacted by the equity business.
For full fiscal year 2024, Siemens Financial Services anticipates to further gradually improve earnings before taxes over prior year. Ladies and gentlemen, excellent and consistent free cash flow is the ultimate yardstick for performance. In the fourth quarter alone, our industrial business delivered free cash flow of EUR 4.1 billion and an excellent cash conversion rate of 1.22. A new record of more than EUR 10 billion for free cash flow all in throughout the year, and almost 13% cash return on revenue, highlight our focus on stringent working capital management of the entire team around the world. We are very confident to continue this path also into fiscal 2024, despite macro volatility, and for the 5th year in a row, we strive for a double-digit cash return. Strong operational performance and cash generation is also reflected in further improved capital structure.
Industrial net debt over EBITDA was 0.6 times at year-end, providing headroom and flexibility for stringent capital allocation. With our strong investment-grade rating, we are in an excellent position for refinancing in fiscal 2024. The pension deficit is at a record low of EUR 1.4 billion, and we will have further opportunities for cash generation from portfolio simplification. Our strong free cash flow, capital structure, and liquidity position are also giving us ample room to provide consistently attractive shareholder returns. We will propose to the AGM a dividend of EUR 4.70, clearly up by EUR 0.45 from the prior year dividend, matching our progressive dividend policy. This represents an attractive dividend yield of 3.5% based on September, and closing share price of EUR 135.66.
At the same time, we are mindful of ensuring balanced capital allocation priorities. The current share buyback, originally planned until 2026, is 90% completed, with a buyback volume of EUR 2.7 billion and an attractive average buyback price of EUR 118. Therefore, we decided to launch a new upgraded program of up to EUR 6 billion, up to 5 years, right after completion of the current program. Now, let me come to the assumptions for our outlook for fiscal 2024. We assume a volatile macroeconomic situation, but no further increases of geopolitical tensions throughout fiscal 2024. Under this condition, we expect our industrial business to continue its profitable growth path. We anticipate the economic equation of price increases and productivity versus cost and wage inflation to be, again, net positive in fiscal 2024 for both Digital Industries and Smart Infrastructure.
Building on our strength, we further maintain high levels of R&D intensity, with a strong focus on connected hardware, software, and digital technologies. In addition, we will continue to selectively invest in go-to-market digital sales channels, vertical-specific and sustainability offering. However, each decision will be taken with a strengthened focus on strategic imperatives in resource allocation. To support midterm growth momentum, we will also increase CapEx in line with our strategic investment initiative to expand capacities, drive innovation, and resilience. We assume severance charges below prior year level from today's perspective, in a range of EUR 250 million-EUR 350 million. Based on current rates, we anticipate a negative effect of around 1 percentage point on top line from exchange rate and a burden on profit margin of around 30 basis points, primarily in the first quarter of fiscal 2024.
On page 36 in the appendix, you can find all details as reference for our outlook below industrial businesses. I want to point out here only a few important topics for your models. In portfolio companies, including Innomotics, we are confident to achieve an operational margin of more than 5% again. Fiscal 2023 profit included a gain on sales of commercial vehicles of EUR 148 million. Cost of governance, net of Brownfield, will be materially lower, in line with our intended path of consistently decreasing this item to net zero by 2026 latest. The tax rate is expected to be in the range of 24%-29%, which we see as a regular rate without extraordinary effects. Here you can see the outlook for Siemens Group and for the businesses.
Given the strong performance in fiscal 2023, our guidance is based on tough comps, especially when looking at the order development. It reflects our confidence in the continued high-value growth, despite challenging framework conditions in fiscal 2024. Digital Industries expects comparable revenue development of 0% to 3%. This is based on the assumption that following destocking by customers, global demand in the automation business, especially in China, will pick up again in the second half of fiscal 2024. The margin is expected at 20% to 23%. Smart Infrastructure expects to achieve revenue growth of 7% to 10%, with a further improved margin of 15% to 17%. Mobility anticipates achieving revenue growth in the range of 8% to 11%, with a margin of 8% to 10%.
On Siemens group level, we anticipate 4% to 8% comparable revenue growth and again, a book-to-bill above 1. We expect this profitable growth of our industrial businesses to drive basic EPS from net income before PPA accounting, excluding effects from Siemens Energy, to a range of EUR 10.40-EUR 11 in fiscal 2024. This outlook excludes burdens from legal and regulatory matters, as always. As you can see from our ambitious outlook, we enter fiscal 2024 from a position of strength with a leading portfolio and stringent execution. However, we monitor the macroeconomic volatility closely to be able to act in an agile way. Our direction is clear: we will deliver further value creation by profitable growth and resilient cash generation. With that, I hand it back to you, Eva.
Thank you, Ralf. We are now ready for Q&A. Please limit yourselves to two questions per person, because we want to give as many of you as possible the opportunity to raise questions. Operator, please open the Q&A now.
Thank you, ladies and gentlemen. Anyone who wishes to ask a question may press star followed by one on the touch tone telephone. If you wish to remove yourself from the question queue, you may press star followed by two. If you are using speaker equipment today, please leave the handset before making your selections. Anyone who has a question may press star, followed by one at this time. Our first question comes from the line of Ben Uglow, Morgan Stanley. Please go ahead.
Good morning, Roland, Ralf, and Eva, and thank you very much indeed for giving me the question. Okay, so I've got two. Let's just do them in order. The first is really around the DI margin guide. It's an obvious question, but your 20% to 23% does imply that we are seeing slower margins, you know, maybe one or even two percentage points in the first half of the year. Well, or what I'd like to understand is, qualitatively, big picture, what is behind that, you know, that lower margin guide?
My assumption, which may indeed be wrong, is that we're thinking about slower volume primarily in the big automation factories in Hamburg or Chengdu, or wherever it might be, and that volume is typically quite sensitive with the automation product margin. Is that really what you're trying to communicate? And the reason why I ask is there are a lot of, well, there are a lot of theories in the market, should we say, about software mix, and software mix materially improving your margin this year. It sounded like you downplayed that in your opening comments, but Are you really reflect what you think is going to happen to volume in automation products, or is it something else? That's my first question.
Shall I start with that right away, Ben? Thanks for asking. I mean, you can probably imagine this was also on top of our minds-
Mm-hmm
-when we have been forming and shaping the guidance for fiscal 2024. I mean, if I may walk you through the framework first and then conclude in the end. I mean, it's obvious that we do see challenges in growth markets like China. We do have all that, what we discussed, and I'm sure we're gonna discuss that also in today and later on when we meet you in London. That, the destocking and, let me call it, the uncertainty in the channels is playing a major role there. But if I may point out four areas to think about when you look at the margin guidance of DI. First and foremost, just to get it off the table, exchange rate will be unfavorable for us.
Mm-hmm.
I have been pointing out first quarter, it's gonna have a negative impact of 100 basis points on margin.
Mm.
No one knows, obviously, where we see the exchange rate to go, on the way forward. But, I mean, just looking at the current status and anticipating what that would mean potentially for us for full fiscal year, this is a material impact for DI, mainly. Then you already touched on the mix, and when we talk mix, we have actually three dimensions to consider. The first is products and software. You're right, software momentum has been kicking in. I mean, we talked about the backlog, obviously also reflecting the successful transitioning to SaaS models. That means that revenue recognition is delayed. You know, all the mechanics, I don't need to mention that. So volume increase does not necessarily fully reflect the potential of earnings power in that business.
At the same time, just reminding ourselves, we continue investing in the SaaS transition. Not to dig into that further at this point in time, but we have been highly motivated, let me put it that way, by the customer response. So the increase in ARR growth rate and the cloud portion in it have been very encouraging. So we feel we are on the right path, and as always, we will follow the voice of our customers. We have been well advised doing so and will continue so. So seeing the bottom of the fish, so to speak, does not necessarily mean that we have a step change right away, but we continue investing as long as we hear the voice of the market.
So software product mix or the software automation mix is the one dimension, but also the product mix within automation is playing a role, of course. I think you heard me saying that process industries have been benefiting from the latest development. Obviously, this is not the peak of our margin in portfolio perspectives, and therefore there is a mix in the automation business, that has been starting to be not unfavorable, in the meaning that it's not worth going for that business. It's quite the opposite. We are occupying the place at the customers, and we are winning market share. But the mix and the resulting also capacity utilization you have been touching on, is playing a role, of course. This will be temporary in nature.
So therefore, the mix in automation, mix between software and hardware, and also third dimension of talking mix is geography. You heard us talking about growth rates in the past in highly profitable countries that do no longer provide for that massive growth, and therefore, there's also a geographical aspect in that mix. I hope you forgive me that I don't get into the details of this one. Pricing is artwork these days, and we will stand firm because the price increase that we have been pushing into the market for the win-win situation we create with our products needs to be defended now, and this is really giant work at the moment. It's reflected also a bit in the fact that we have a different pattern, timelines in our economic equation.
I mean, just quickly referencing back to 2023, when we have been starting with a good positioning from a price increase perspective. So price increase of the prior, prior year, 2022, was in the backlog, has been worked on. At the same time, factor cost increase, in particular, wages, have not been fully up to the levels we expect now for 2024. So therefore, there will be a positive economic equation net for the full fiscal year for DI and SI, but the structure and the magnitude are not going to play the same league. So timelines, if you will, are less favorable than they used to be in 2023 when it comes to matching price increase and productivity with factor cost increase, mainly from merit increases. And it's obvious, we all know that productivity measures do not kick in from the very beginning on full impact.
So therefore, there's also a natural timing in that, that is geared to the second half of the fiscal year. And, with that, I think I just wanna repeat what I said before. Despite that, slower momentum in this fiscal year on top line, in DI, in particular in automation, in some key markets, we continue to invest in R&D because we feel this is the golden moment to make a difference. We win market share, we get the customer response, we make a difference, and we are accelerating our accelerator. So from that perspective, it makes a hell lot of sense to continue investing. The assumption that we made, and I think I spelled it out clearly, is second half of the year, we expect a pickup in demand again.
Mm-hmm.
We are also ready to pull the brakes if need be, if that assumption doesn't kick in. All that together, in a nutshell, has been shaping our view on fiscal 2024 for DI automation, mainly. And we, of course, will use each and every opportunity to grab market opportunities coming up, and we will be ready to accelerate if we can, but we are mindfully watching circumstances and also the market sentiment. I mean, high interest rates and the question, where will they end, is not definitely encouraging our customers' investment sentiment at this moment. But you can be absolutely sure that we will be able to accelerate, and we will also be able to pull the brake if need be.
That's understood and very helpful. Thank you. My one follow-up is just about the distribution channel. I mean, Ralf, you always give us an interesting kind of view on the so-called artifacts and where we are in the destocking process. If we look around the world, I think we all sort of know what's going on to some extent in China, but how do you see the relative degree of destocking between China, Europe, and the U.S.? Where are we sort of globally in that process, in your view?
I mean, if you allow, I just have a short look at macroeconomics for China before I come to discussing the China channel situation. But geographies around the globe, I mean, if you compare them, it's obvious that China is the biggest challenge at the moment. And it's also obvious that in particular, Germany, to a certain extent, correlates with China from the export perspective.
Mm-hmm.
So I would see a distinct connection between the two of them. They are not fully independent. This dependency is, of course, on far lower levels in our industries when it comes to the U.S. The U.S., we see a market that is driven by process industries mainly-
Mm-hmm.
and is also giving us opportunity to grow into market shares. We are not that strong in the U.S. yet, and we are working on that, as you do know. So there is a natural set up that China is destocking or China's destocking impact is bigger on us, than in the U.S., where we don't have that magnitude yet. So priority China, therefore, let's have a quick look at China. I mean, from a macroeconomic indicator perspective, I'm sure you follow them as I do. In October, there were no real tangible signs of markets sustainably recovering, and there was also a drop in exports. PMIs have been falling below 50 and declining. PPI and CPI do not suggest a recovery anytime soon.
So good order intake in the first couple of days of the new fiscal year, which we had.
Mm-hmm
... is not a real true and,
Mm-hmm
... solid signal for recovery. That's why we are carefully and prudently observing that in our outlook we are giving for the first quarter and the second quarter-
Mm-hmm
... of the fiscal year. So, talking our channels, when you look at the distributors that we have, there's still high levels of stock on their shelves. The outbound deliveries of our distributors do rather indicate a slow backlog conversion and destocking speeds. This may change quickly. You do know that from the past, if momentum is kicking in, in China, you need to be ready to deliver, and that's why we need to strike the best possible balance between those two different scenarios. Being close to the market and to our customers is of the essence, and we, of course, also have a very mindful view on the local competitors there. So taking all that together and concluding, my gut is telling me that we won't have a clear picture before Chinese New Year.
Even though I don't like it, we need to be patient with more detailed estimates on the development there. For ourselves, looking a bit just as the numbers you do know, and I need to say that again, we don't have a complete closing process for October, because we are busily closing the fiscal year and doing all that which took us to the position to talk to you today. So no firm closing in October means only indicative figures also for myself. And there was a positive signal, to be honest, in the new orders in automation in China in October. It was a clear pick-up over a very weak September, and also August and July, you know that have not been really stunning in that field. So one month, two weeks of a signal to draw conclusions on.
Looking at revenues, I mean, typically the first month in the quarter is anyhow a bit weaker. If you compare the first months of the quarters, behind ourselves, I think that was also on level. So I would say there is hope, but no firm conclusion possible at that point in time, whether the unwinding of the backlog will be accelerated or whether it will take us those two to three quarters that I had been mentioned a couple of times before. So on a world level, finally, when we talk new orders, October figures, as preliminary as they are, unaudited and not a full closing cycle, as I said before, they are pretty much on level of September, August and July. So therefore, there seems to be a trough that has been reached, and we are very carefully looking at that.
We stay close to business sentiment as possible, talk to customers, and we are ready to react. That's the only thing we can do at that point in time.
Understood. Very helpful. Thank you very much, and I'll pass it on. Thank you.
Our next question comes from the line of Andrew Wilson, JP Morgan. Please go ahead.
Hi, good morning. Thanks for taking my question. I've got two. I think the first one is something of a follow-up to Ben's. I guess I'm interested in terms of the information you're using to talk about a trough in on the automation side. I mean, obviously, you've alluded to some of those kind of early numbers, I guess, from October. But in terms of, you know, how confident are you that your visibility of that picture has improved versus earlier in the year, where obviously it proved to be a very difficult market to call? I guess, just trying to understand sort of that information flow and whether, I guess, we sit here with better confidence today on the understanding of what are clearly a lot of moving parts there. If I stop there.
Thanks, Andy, Andrew. Very good question, of course, and I mean, what I'm referring to is typically four different sources. I mean, we're looking at macro as you do. There's an abundance of views out there, when and how a potential pickup can take place, so we are just clinging to the numbers that I have been quoting before. Then, we, of course, are looking at the market. We see the dynamic, we talk to customers, we conclude. We also draw our own conclusions. I mean, when it comes to interest rates, you typically know what the reaction in which part of the market is gonna be if there's uncertainty or not. So, that's the second source, the market, if you will. And then it's our current trading.
This is unfortunately, as I said, in the other quarters, I have firmly booked figures for the month that lies behind ourselves when we talk to you, typically in October or in November, as we are. And as we speak, October figures are not that firm. That's why I had to put that indicator. Trading, our own current trading is the third source. And then, of course, we are talking to our channel partners. They have their own views. They are combining, so to speak, in particular in China, the conclusions you would draw from interest rates, market sentiment, and also their own stock level policies, if you will. And used to call that artifacts in the past, and I apologize if that sounded disrespectful to them.
They do a meaningful job for themselves, but it's hard to conclude on a broader level what that means to the market because some of them may opportunistically look for opportunities to grab them. Is it pricing? Is it their own customers? And others are more strategically allocating their resources, so it's hard to take a pattern from that. But it's a very valuable source to conclude, because the change in that what they do is giving you indications. That's the reason why I said the stock levels at our distributors in China didn't change a lot. That means their outbound flows are not increasing, and that's why we believe at the moment, we may rather be at a bottoming out process than in an early pick-up pattern.
This all concludes, from our point of view, that at the moment we shouldn't be over-optimistically looking at a change in momentum, but they are clear, those long-term trends and indicators that have been leading the market in general, and they are still intact. We also hear that from our Chinese partners and our Chinese sales force, that there is not a structural lack of demand. It's rather that unwinding of this complex situation that has been building up throughout the last two and a half years. Let me add just one comment, which we didn't talk about yet, which is there's a kind of a transformation in the market itself. China's and the Chinese companies are pushing very hard also into sustainability kind of solutions. Is it efficiency? Is it any kind of new technologies?
I mean, you can now count it down, batteries, hydrogen, stimulating any kind of photovoltaic, whatever it is. And that's another shift within the Chinese market, along with a second one, which is I would call it. I would use the words of the government. They call it high tech manufacturing. In times where the world is competing for direct investments, and China is fighting obviously against this resilience trend, so they have to defend their own manufacturing strengths. Obviously, they have to drive for higher productivity levels while using less resources, which is really a very, very strong push into high tech manufacturing. Also, in particular, for roughly 350,000 small and medium-sized enterprises.
That happens as we speak, to rebuild, so to speak, and needless to say, that this is also a good tailwind and potential for us.
That's very helpful. Maybe for the second one, it's still on DI, but on the software side. I guess I just wanted to make sure that I'd understand or understood, rather, the comments on the sort of demand picture, I guess, for 2024. It sort of sounded to me that there was a good deal of optimism with regards to demand on the software side, and obviously task continuing. But on EDA as well, Q4 was clearly fantastic, absolutely fantastic. How should we think about the pipeline for activity on EDA in terms of 2024?
So thanks for appreciating the development of our software business. I mean, there's three aspects about it, and Roland has been touching on two of them. I mean, first, there was a huge unseen accumulation of large contract wins in the fourth quarter, which had an impact that we never saw before. I wish we would do that quarter-over-quarter, but unfortunately, it won't. The reason for that, we discussed a couple of times, projects of our customers, finally taking them to the decision to change to Siemens or to use our software, is driven by a long-lasting preparational effort before they conclude. So, we do see more projects ramping up, unfortunately, not in the first quarter of fiscal 2024, but this is not embarrassing us.
We do know the nature of that business. It's lumpy, and we would not ever step into the trap of trying to push our customers. This is not advisable in no business at all. So the other one is that parts of EDA may also be subject to subscription type of transitioning. It's hard to predict, as always, also for the PLM business, we are following the voice of our customers. They set the pace, so therefore, there will be momentum picking up. Is it going to be material or not? I don't think it's going to be material in 2024, but it will be in the long term.
Now, the third element, PLM, transitioning to SaaS, I hope you agree that it's really impressive how we have been picking up momentum, how our sales force and our delivery forces are getting that onto the ground and obviously reaching exactly that part of the market that we have been wishing for. Meaning 80% of mid-sized companies that are buying Siemens now is a huge opportunity for us. And the momentum we have been creating with the numbers of customers being addressed, more than 11,000, with a portion of cloud-based solutions growing faster than honestly, I personally expected. This is giving us opportunities. At the moment, however, and I mentioned that when I tried to answer Ben's question. At the moment, however, this is not popping up in top line and not in income at the moment because the transitioning has a burden.
That's why we stay very transparent in sharing those KPIs with you that we believe are giving you best possible transparency. And as Roland has been putting it into a nutshell, I think we are right at the bottom of this transitioning, as we call that. But that doesn't mean that margins are already visibly improving on a level that it has impact on DI overall. So, in a nutshell, from a seasonal perspective, I mean, you saw us in last fiscal year, 2023, talking about seasonality, where we were back and loaded. We said that from the very beginning for the software business, and from today's perspective, it looks to me it may not be that dramatically in its extent as it was in 2023.
But again, we will be back and loaded, in particular, when it comes to the highly profitable EDA business.
That's very helpful. Thank you for your time.
Thank you.
The next question comes from the line of James Moore, Redburn Atlantic. Please go ahead.
Good morning, everybody, and thank you for the opportunity. Could I ask a DI margin question and return to that and follow up on the buyback, if I could? Thanks for all the answers to Ben's question, Ralf. I just wondered if we could unpack it a different way. In terms of the currency, could you give us a rough idea for the year at current rates, what that could look like? And on investment, could you size the 24 cloud investments and say if we should expect anything outside of that in select or R&D intensity, that could be impacting margin? And I guess my core question is away from Innomotics and currency. When we look at the organic margin in software, I hear what you say about the bottom of the fish doesn't mean margin visibly improving to the degree that it moves the DI margin.
Do you still stick with the original plan laid out two, three years ago? On automation, I would have thought that the economic equation would have offset the volume and wage scenario. If we had neutral mix, would you expect the automation margin to progress? Is the topic just entirely mix, SA, China, et cetera?
Wow, that was quite a lot of topics you have been putting onto our plate. Let me, let me start with the easiest one. Software transitioning, SaaS transitioning, yes, we stick to the commitments we made. We don't know the timing exactly as we said, but we feel very much encouraged that the momentum we have been creating is very, very strongly supporting the commitments we gave. And, the pattern of the fish or the, the fact that we use the form of a fish to describe the business, is also showing that once you then pick up with volume and have less incremental burden on your P&L, it will still take 6-8 quarters before you see the full beauty of the impact.
When it comes to automation and the economic equation, I mean, it's about timing, if I may put it that way. Yeah. What we saw, and I tried to describe that, we had, thanks God, very early, touching the pricing levers in the beginning of the inflation, high levels of inflation kicking in. At that point in time, then back then, unfortunately, delivery times have been extended, because there was scarcity of material in the market, and therefore, a lot of the orders with good pricing have been shifted into 2023, even though they have been originating in 2022. At that point in time, in 2023, then when we executed, there was a wage increase expected, but not fully effective yet. Now, in fiscal 2024, we see the full year effectiveness of a wage increase of give or take 6%.
While pricing doesn't create incremental levers anymore, I, I would be happy if we got along with a pretty stable global pricing tag. There will be challenges in some markets with local competitors, which are trying to use that opportunity, of course, like in China. So therefore, not a lot of opportunities to counteract with pricing. Now, what do you do if pricing doesn't do the trick? You turn to more productivity measures, which have a certain lead time before they come effective. So again, timing difference. And if you add all that together, you come to a point that you see no further impact, incremental from a pricing perspective, heavy impact from wage increase, productivity measures being on their way, but not fully effective yet.
Before the second half of the year, I wouldn't expect them to be in a degree of implementation that are materially having impact on margin development. This is not rocket science. I know it sounds a bit complex to you guys, but this is our normal course of business here in trying to lead this company, that you accept that, you push, but if you push too hard, you may end up in wishful thinking, and this is not the territory Roland and myself want to be. So therefore, we are facing the brutal facts of the pattern, and we are managing it as well as we can. Talking, your question about exchange rates, we don't speculate.
I mean, what we do is we just take the exchange rate as it is, anticipate with forward points in the market, then what may happen, and at the moment, the average rate for US dollar we see for fiscal 2024 is around 1.06, and for China, it's about 7.7, give or take. So this is what we see at the moment, yeah, and, therefore, it's unfortunately a fact that the first quarter will be hit hard. I know you wanted to talk about share buyback, but you didn't ask a question yet.
Maybe I could just ask on that briefly then, and thanks for those answers. Great to see the intensity of that doubling, but given your impressive free cash flow and the prospects on that front and your strong balance sheet, could you talk a little bit about the discussion on how you came to that as a size, and why not say EUR 2 billion a year?
Yeah, I mean, that's easy to explain. I mean, you know that I have the pleasure to do this for 10 years now. The first two buybacks, we ran into the trap that we have been taking a time frame that has been pushing us then, and it didn't help because share price was not ideally developing in a relatively short period of time. We made a couple of bankers happier than they should have been, and we learned from that. And the execution of the current plan as it is is pretty much encouraging me that we have been moving into the right direction. We deliberately are picking a longer period of time. We set current plan, EUR 3 billion for 5 years.
... We have been then opportunistically using the opportunity. It's hard for me to say this is an opportunity if you have a low share price, but that dip that we all took has been allowing us to accelerate swiftly. You could see that we have weekly disclosure on that matter, and we use that. So the output of this process of acceleration is, I believe, a meaningful average buyback price of EUR 118. So EUR 3 billion in five years, ending up in EUR 3 billion in two years, give or take, is quite encouraging, I think.
If we now do 6 years and EUR 6 billion in 5 years, and again, use opportunities that the market may provide, ending up with a shorter period of time, I would then be happy to announce another plan, rather than committing myself at this point in time to buy back higher volumes in a shorter period of time and then being trapped in an unfortunately set up in the market.
Very helpful. Thank you very much.
The next question comes from the line of Alexander Virgo with Bank of America. Please go ahead.
Yeah, thanks very much. Good morning, everybody. I appreciate the opportunity to ask a question. I guess the first one would probably be on the Smart Infrastructure margin guidance. Very, very encouraging to see that now well above 15%. And I wondered if the time has come to review the medium-term margin targets there, and whether you could give us some qualitative comments, perhaps around the profitability across the different verticals in Smart Infrastructure, particularly given the support you've got from backlog there. And then I guess the second question, just a sort of a follow-up really on free cash. Would you sort of start to think about being able to guide on free cash, or at least start to talk about it with greater consistency?
I'm thinking about the consistency of conversion now, particularly across the I and SI, and thinking about how we should be forecasting your generation for free cash flow generation over the next couple of years. Thanks very much.
Thank you. We are very happy about the development of SI, as you can imagine, too. It's driven basically by a very, very strong demand from the market for the portfolio, which we have, obviously in the whole electrification space, but also in the building space when it comes to building product and the like, and the sustainability demand. Just to give you, I mean, you know that electrification group by 25%, electric products by 9%. This is a very strong demand, and this is also driving, obviously, a conversion.
So now I quote, Matthias, when he talked about, the development of the electrical product, and he compared it with the competitors and competitor we have, and he said, "We closed the margin gap." So, so that gives you an idea, how we are working on productivity in our manufacturing sites. Needless to say, that we use our own technology there, and we are delivering better than others. This gives us the confidence to invest EUR 150 million in a new electrification plant on the back of a order from, hyperscalers, and there are more to come. So therefore, I mean, we are, we are extremely strong in us- obviously, also in a very strong portfolio. You know, that we renewed our portfolio, switching portfolio, core technologies, as well as the, the related, tools around it. And there's another element in it.
We are very good in translating customer demand in the, let's say, specific switch gears, which are then running in high volume in manufacturing. This obviously gives a high conversion. Another one is they worked extremely hard also on the economic equation. I think it's at the end, the equation, economic equation of SI was even a notch higher in fiscal year 2023 than that one of DI. I mean, just recognize it. So very, very well worked. Everything what Ralf said is also true, obviously for SI. We see a little bit of a moderation in the market, but still a strong trend in electrification. We see the salary increase kicking in fully. Pricing is, it's still, I would say, a little bit better than for SI.
But, but therefore, I mean, if you take all this together and look in the growth perspective which we have, this suggests also that we bring another conversion, which links us then also to the guidance. Last point, you obviously recognize that we have a financial framework which is getting a little bit tight for SI, and we are looking into that. Yeah, and let me take the point around free cash flow. I mean, first, thanks for appreciating the consistency that has been also accomplished over the last couple of years. We are very proud of our teams, that they managed to really get a grip around asset management in daily business life. It's not that easy for some of them.
I think the teams have been getting a really firm grip around the different levers when it comes to managing working capital. There will always be ups and downs, of course, and the team is getting also more and more experienced in managing those ups and downs. That's what we then see also in the seasonal structure of the Free Cash Flow. You have been asking whether or not we would dare to start guiding on the matter, and I thought I heard myself saying that we are very confident to continue this path that we have been embarking on in 2023, also for fiscal 2024, despite macro volatility, and for the fifth year in a row, we strive for a double-digit cash return on sales.
It was not part of my speech in the guidance piece, but I still believe this was a strong indication where we want to go. Before we really come to commitments on that matter, I think we need to be mindful also of that what's happening below industrial business. Because, I mean, as well as they are managing their working capital, there's quite a chunky impact below the line of industrial business when it comes to tax payments. You may get a tax audit, and the cash in or out from that is completely unperiodically hitting your Free Cash Flow statement and your balance sheet. The same also for derivatives from hedging.
You do know, I mean, the better your hedging is getting, be it risk in the ex-exchange rate, be it risk on the interest side, it's always derivatives in place, and the better you get, the more you can resolve. And that does not necessarily mean that you hit the perfect timing for that. So there's volatility that goes beyond control. Therefore, it's very hard to give guidance on that one in a very specific, ideally quarterly way. But we are working on that, and the fact that we commit ourselves to that, what I mentioned before, again, I think that's a clear signal how committed Roland, myself, and the entire managing board and the leadership team of Siemens globally is committed to this pattern continuing on the way forward.
Great. Thank you very much.
We'll take one last question.
Today's last question comes from the line of Gail Aubrey with Deutsche Bank. Please go ahead.
Oh, thanks. Thanks very much for squeezing me in. Good morning, everybody. I've got two, please. Maybe the first one is around mobility. Some of your peers have had some issues in ramping up production in the past few quarters or even years, maybe, well, not as much as originally planned. So I wonder if you could talk a bit about this, you know, around the potential supplier issues and capacity constraints you might have had or think you may have in the future. I mean, that, I think that's an important topic, given the very big backlog you have. And then the second question is around Siemens India. So you're putting EUR 2.1 billion to get a higher share.
But of course, the transaction is not completed yet. I wonder how much you think you will eventually recoup from the sale of the Indian energy business to Siemens Energy in, I think the timing is around 5 years. If you could elaborate maybe on the terms and conditions for this transaction.
Hey, thank you. So let me start with mobility. As you can imagine, we are very happy with the development of what we see at mobility. I mean, a EUR 20 billion order intake, meaning we are capturing market share in a very attractive market that's growing. And this is fired by rolling stock as well as rail infrastructure. Very nice. And then we also see this business delivering cash flow. I mean, EUR 1 billion, which is not that obvious and not that easy if you compare it. So, we see the supply chain is almost back to normal. The only limit is some electronic parts to the rail infrastructure. It's normalizing. We are watching that closely.
But from that perspective, and you can see also our revenue development, we are not really held back from supply chain anymore. We have a very strong order intake turns into revenue. So you see us also investing in new manufacturing sites, assembly sites in the United States, in a strong market. We are gearing up now our activities in India, which is very interesting. And obviously, we're looking also for capacity improvements in Europe. All in all, this is a very, very strong, very good development. There's another element in it.
Customers are tending more and more to look into the sustainability aspect, meaning buying the highest efficient drives, but also the way how you maintain your assets and have basically a longer life cycle of assets, which goes back to a very strong maintenance. We are extremely good at it. Our Railigent X platform gives us visibility on all our trains. All our trains are connected, which we deliver. Then the last thing is underinvested rail infrastructure, and it's not only Germany, it's in all other places, requires for more and more investment. Needless to say, this goes definitively into high technology, so signaling, also signaling the cloud. The first test in the market in Austria was very successful. Others will follow, and we are in a leading position.
There's no other player in that market who can deliver this kind of technology. So you see us quite bullish on this one. And we have to say that Siemens Mobility is the champion in the market, and we were expanding our leadership there. On this sale deal, I mean, the mechanics are actually quite simple. We are buying 18% with a discount of 15% from Siemens Energy. And obviously, these 18%, they continue anyhow, 75% of our own business. It's only the smaller portion which contains the Siemens Energy share. Once we have that, then we can go into... I mean, some people call it autopilot, which meaning triggering then, number one, the split between these two businesses within SIL, finally spinning this, those apart with a mimicked shareholder structure afterwards.
Which allows us then to sell our shares in the energy part into the market, ending up then finally selling the share, which Energy would still have in the Siemens Limited India, back to us and vice versa. Which will end up then in after a timeline of something like 4-5 years in us owning 75% of SIL and Siemens Energy holding 51% of SIL, so Energy. This is the plan. We do have in the contract a kind of a breakup fee, so it really makes an extremely high barrier for Siemens Energy not to do this buying back. So we want, and actually they want, and anyhow, they want this business back because it's India, it's a growing market.
So for us, it's a very smart combination of, number one, allowing us to accelerate the decoupling in India and at the same time, supporting Siemens Energy with EUR 2 billion cash. And again, I can reemphasize that we have a 15% discount on that deal.
Thank you very much.
Thanks a lot to everyone for participating. As always, the team and I will be available for further questions, and we look forward to meeting many of you at the sales side meeting in London later today and during our upcoming roadshow. Have a great day and goodbye.
Ladies and gentlemen, that will conclude today's conference call, and you may disconnect your telephone. Thank you for joining and have a pleasant day.
