Good afternoon, and welcome to Bilfinger's conference call on the first quarter of 2021. My name is Bettina Schneider, and with us today in the line are Christina Johansson, CFO and Interim CEO, as well as Duncan Hall, COO. Christina and Duncan will now present on Bilfinger's business development in the first three months of the year. For the moment, your lines are put on mute. Afterwards, we're happy to answer your questions. With this, I hand over to Christina Johansson.
Thank you, Bettina. Ladies and gentlemen, welcome also from my side to our conference call on the development of Bilfinger in the first quarter of 2021. I'd like to start on page two, where I would first like to give you a short overview of the key figures reflecting the encouraging performance of our company in quarter one. In most of our markets, we are experiencing an increase in activity level. In our upstream oil and gas activities in the North Sea, however, there were still COVID-19-related logistical restrictions. Orders received were almost stable organically, and again, we reached the EUR 1 billion level with a very robust European engineering and maintenance business. In North America, we have been awarded a sizable project that I will come back to in a minute.
Revenues were down by 5% organically against the prior year quarter, when sales, however, had not yet been materially affected by the COVID-19 pandemic, nor by the substantial oil price reduction in March 2020. Only from April, we had a significant impact on the revenue last year. In current year, the E&M Europe and Technologies segments regained a solid level. In E&M, international project business was still modest, but in line with our expectations. With a positive EBITDA adjusted of EUR 11 million in the first quarter, Bilfinger is demonstrating its increased cost agility it has built up during the past year. We see this as encouraging evidence that we are getting closer to one of our goals, a less seasonal earnings profile, which our operations achieve thanks to more agile capacity management, especially in the first months of the year when revenues are typically lowest.
Reported free cash flow also improved significantly to -EUR 28 million, after -EUR 93 million in prior year first quarter. The improvement due to successful working capital management measures that already made a very much progress last year and continued in the first quarter. On that basis, we are happy to confirm our 2020 outlook today and expect further progress during the year. We would now like to provide you with a short overview of the market developments in our three business segments, and I will hand over now to Duncan Hall, who will give you some insights here.
Thanks, Christina. Good afternoon, everybody. I hope you're all safe and well in these challenging times as they continue. It's great to talk about a really good start to the year across the board on safety, efficiency, and orders. Our workforce agility that Christina briefly mentioned really supporting much improved Q1 utilization. We'll come onto that a little bit later. In our markets, starting with E&M Europe, we are starting to see recovery. Some of the investments are underway and developing, but we are seeing a significant increase in shutdowns as well, which keeps our resources very busy. We'll see a very busy 2021 and 2022 associated with shutdowns as events were moved out of 2020 into those periods of time. In Energy and Utilities, the drivers are still there, and actually these markets have not been seemingly impacted by any of the pandemic.
In fact, with stronger government and corporate push into these areas, we're actually seeing momentum continue, if not increase, within the green energy investment areas. In oil and gas, whilst it has been challenging and offshore still has some restrictions, we'll see those ease up in the North Sea in the latter half of the year as vaccination takes an impact. There is consolidation of the supplier market, which works very much in our favor. We have very clear integration that people want to purchase, we're seeing those opportunities come through thick and fast at the moment. Gradual recovery is there. We're starting to see plans now in half two for catch-up maintenance work and backlog within those environments.
If we move into international, a similar theme, where North America, the pipeline is starting to emerge for projects as business opens back up. Again, expansion and modernization in the Middle East continues. What's very positive is with the new president in the U.S., we're starting to see increased interest in public spending into infrastructure and also green energy investments focused around renewables. We have businesses that can capitalize in those areas. Similar to Europe, we see CapEx and OpEx within oil and gas start to increase towards the back end of the year as confidence in oil price stability continues. If we shift into Technologies. Not to talk about energy transition again, but focus a little bit on nuclear. The investments are continuing there, as we expected, with also new opportunities emerging and coming through in different territories, which is very good.
In pharma and biopharma, very good mix of modifications and new work is emerging, and we're making good progress in getting into maintenance work as well, where efficiency is now becoming more and more important in these industries as well. I'd now like to just give you a few examples of where we have won work and also why do we win work. Part of our DNA and part of our whole, how do we win, what's our culture, is safety. Safety and efficiency go hand in hand. Here's a great example in Germany of 17 million man-hours since we had a last lost time injury. Difficult to say, even in your native language. How do we achieve that? Well, that's a lot of commitment. It's leadership and it's visibility. It's sharing, it's learning, it's interactive.
Safety days out on the plant, safety awareness training, making sure we have the right tools and equipment to do the job. More importantly, in recent times as well, is adapting to the environment that we have in using digital tools to really efficiently prepare and execute the work, and then learn from that experience. It's not just in Germany that we see the successes as well. The group at the moment is in a run of 10 million man-hours without a lost time injury across the group, which is 61 days. We last year had a period of over 100 days, and we're hoping to get up to those levels again. If we now look at some of the work we've won. Christina referenced earlier a major project in North America, and this was secured with a key customer for Bilfinger, INEOS, who we work with worldwide.
This is a major order intake in triple-digit millions of dollars, a significant construction period of time over 17 months. We're less than 10% into the project now, but it's had a good start. What is the work? Well, it's installation of pumps, compressors, steel work, as well as electrical work for ourselves. We are also self-delivering the scaffolding in this particular area. That was a big appeal for the customer. They did not want to be subcontracting and managing a lot of interfaces across different suppliers, so they selected us to do this for them. That integrated offering really offered savings in both management time and risk to the customer. If you want the comparison, it's very similar to the successful Lindby Basscamp project that we executed over previous years. The last area, if you remember well, we talked in the past about insulation.
This is an example of a heat efficiency program at one of our key sites and customers with Shell at Moerdijk in the Netherlands. We work there with over 200 personnel on a regular basis and for many, many years. This is about renewal of insulation, significant carbon savings, heat savings, really getting rid of a lot of the corrosion damage. Why are we highlighting this? Well, in the past, you may recall that the insulation business is a challenging business. Yeah, it's tough margins in there. Here's a very good example of how we combine this with other elements of our work, of scaffolding, with little bits of inspection as well, to improve the value that we can get out of a service. A good example of this as well that we also do is the corrosion and the insulation program that we use.
This is a very good example for us of our strategy in action. Combined services delivering to customers and starting to provide value for them and for us. That's all I've got to say on those areas, and I'll hand you back to Christina.
Thank you, Duncan. I'm now coming back to page 10 with the order development of our group in the first three months of 2021. Orders received amounted to EUR 1 billion, with a slight organic decrease of -1%. The figure remained at a very good and solid level. This was due in particular to a robust development in European markets, as well as to the major project award in North America. Organically, the order backlog grow by 11% to nearly EUR 2.8 billion and exceeded both the figure for the prior year quarter and the figure at the end of 2020. The book-to-bill ratio stood at a good 1.2. Turning to page 11, group revenue decreased organically by 5% to EUR 833 million.
We have to mention here that the prior year quarter, EUR 950 million, had still been largely unaffected by the COVID-19 pandemic that was just emerging at that time.
The positive adjusted EBITDA of EUR 11 million in the first quarter 2021, prior year was -EUR 11 million, corresponds to a margin of 1.3%. This improvement was due to favorable effects from efficiency enhancement programs as well as from improved capacity management. Reported EBITDA was also positive at EUR 9 million after -EUR 20 million in Q1 2020. This also reflects the significant reduction in special items to -EUR 2 million, related in particular to the harmonization of our IT landscape. Following the increased expenses for restructuring measures we had in 2020, we anticipate only smaller amounts for this in 2021. In total, around -EUR 20 million for special items. Here as well, we see that we're getting closer and closer to one of our important targets to close the gap between reported and adjusted EBITDA. Coming to gross margin on page 12.
At 9.4%, the gross margin improved considerably against the prior year quarter, as did gross profit, which grew to EUR 79 million. Adjusted SG&A expenses further decreased to EUR 70 million and were below our sustainable level of EUR 75. This was due to continuing low-level travel expenses and some other COVID-19 related effects. The underlying run rate for SG&A now per quarter is between EUR 73 and EUR 75 million. The adjusted SG&A ratio measured against revenue to 8.4%. Turning to our segments and starting with E&M Europe on page 13. The segment was almost at prior year level, showing again a highly resilient and agile maintenance business. Orders received exceeded the prior year figure as the result of 8% organic growth and reached EUR 675 million. Significant growth rates were recorded, particularly in Northern Europe and the U.K.
Revenue was almost stable. In organic terms, it decreased by 2% to EUR 561 million. Our European maintenance business remained robust, although there was a decrease in revenue as a result of COVID-19 related logistical restrictions in upstream oil and gas activities in the North Sea. The book-to-bill ratio in the first quarter was 1.2. The segment's adjusted EBITDA increased significantly to EUR 16 million, coming from EUR 4 million in the prior year quarter. This corresponds to an improved margin of 2.9% compared to 0.7% a year before. Regarding the outlook for 2021, in E&M Europe, revenues will grow significantly against the backdrop of the normalization of our business environment and associated catch-up effects in the next quarters. Despite an increasing recovery, however, revenues in the upstream North Sea oil and gas business will not yet reach 2019 levels.
The adjusted EBITDA of the segment in 2020 at EUR 69 million is expected to improve significantly. Looking at the E&M International segment on page 14. Here, revenue and earnings are still under pressure. Orders received increased organically by 13% to EUR 161 million. Development in North America was supported by the already presented INEOS project in Texas. In the Middle East, orders received were in the same range as in the prior year. Revenue decreased organically by 28% to EUR 110 million. Adjusted EBITDA was again negative at minus EUR 5 million. The adjusted EBITDA margin was minus 4.7%. The strategic measures we introduced, coupled with a number of sales initiatives, are paving the way to our return to positive development in this segment. The outlook for full year 2021 remains unchanged.
Compared to previous figure of EUR 521 million, significant revenue growth is expected at E&M International. In North America in particular, we are assuming an increasing number of projects that will again lead to growing revenues in the second half of the year. We also expect a significant improvement in adjusted EBITDA to a positive result compared to minus EUR 21 million in 2020. Last but not least, coming then to Technologies on page 15. Orders received in this segment decreased organically by 59% to EUR 115 million. Here, we have to keep in mind that the prior year quarter showed an exceptionally high order intake due to a major contract, including for the Hinkley Point C nuclear power plant in the United Kingdom.
First quarter last year, we had a number of large projects that makes the big difference. Revenue grow organically by 18%, reaching EUR 130 million in quarter one. This emphasizes our growth aspiration for the full year 2021. The segment's adjusted EBITDA was positive at EUR 3 million, coming from minus EUR 5 million in the first quarter of 2020. The encouraging trend seen in the second half of 2020 is continuing. The adjusted EBITDA margin improved to 2.4% compared to -4.3% in the prior year quarter. The outlook for 2021 in Technologies, we anticipate significant year-on-year growth in the revenue that was at EUR 498 million in 2020.
This is due to the high order backlog and the strong development of the nuclear power and biopharma markets. EBITDA adjusted will improve to a clearly positive result after a minus EUR 11 million in the full year 2020. Turning to page 16. Net profit of the Bilfinger Group in the first quarter of 2021 reached a positive figure of EUR 10 million, compared to minus EUR 24 million in the respective quarter. This was also due to the improvement in EBITDA.
In addition, the now final assessment of the value of the preferred participation note for Apleona led to a further write-up of EUR 7 million, which was recognized in the financial results of Quarter One. In Quarter One 2021, our adjusted operating cash flow was balanced at zero after a clearly negative figure of -EUR 72 million in the prior year period. Reported free cash flow also improved significantly to -EUR 28 million due to successful working capital management initiatives. Looking at the liquidity development on page 17. Net liquidity, including IFRS 16 liability, was at -EUR 103 million at the end of the first quarter 2021. The proceeds from the PPN for Apleona in the amount of EUR 458 million were transferred to our bank account yesterday. This increases our ability to proceed on growth opportunities, both organically and through M&A activities.
Compared to the prior year quarter, net trade assets decreased in absolute terms to EUR 432 million. DSO further improved against quarter one 2020 by eight days to 78 days. DPOs were 71 days, a slight decrease compared to previous figures. On page 18, I would like to confirm our outlook for full year 2021. We expect a significant growth in revenue and a substantial improvement in adjusted EBITDA. Adjusted EBITDA margin will return to the pre-crisis level of financial year 2019 of roundabout 2.4%, although revenue in 2021 is expected to be still significantly below 2019. We also anticipate a substantial improvement in the group's reported EBITDA due to significantly lower expenses recognized as special items.
We currently assume around EUR 20 million total for IT and some smaller remaining restructuring. Free cash flow is expected to be positive, but below the prior year level, despite a substantial improvement in EBITDA. Reasons are increased working capital requirements as a result of the planned revenue growth. In addition, there will be some cash out effects for restructuring measures implemented in last year, and also a normalized level of capital expenditure. That brings us to the end of Duncan's and my presentation. Thank you for your attention. We now look forward to take all your questions.
Thank you, Christina. With that, Christina and Duncan are ready to take your questions. If you would like to ask a question, please press zero and one on your telephone keypad. To withdraw your request, please press zero and two. I repeat if you would like to ask a question, please press zero and one on your telephone keypad. To withdraw your request please press zero and two. We currently refresh and we will come back to you please wait. We try once more. If you'd like to ask a question, please press zero and one on your telephone keypad. We're now not sure whether we have a technical issue or whether there are just no questions today. Of course, you all know if you have any questions, please don't hesitate to contact the IR team. Now, sorry. Now the refreshing was successful.
We start with Stephan Bonhage. Bonhage, please pose your question.
Good afternoon from my side. I have three questions. The first one is if you already have more concrete ideas on how to use the cash inflow from the Apleona sale. I think you mentioned some M&A opportunities. My second question is if there's any progress in the search for a new CEO or what is the current status here? My third question is, on your strategic measures and sales initiatives you mentioned in the conference call for the oil and gas business and E&M International, can you give more light about that? Maybe you can also give a general assessment of the prospects in the oil and gas business this year. How strong should be the recovery, especially in the second half of the year? Thanks.
Thank you. We will try. I suggest I start off with the first two questions. Duncan will proceed. When it comes to the Apleona proceeds, how to use them, there are traditional ways how we can use this money. Obviously, Duncan and myself and the Executive Board believe that we will be able to present a good value for acquisition that would also then support the way forward for Bilfinger. We have some ideas in this M&A strategy. We will try hard to also convince our Supervisory Board to spend the money, at least a part of it, on additional acquisitions to support the growth of Bilfinger, not only organic growth, but also then M&A growth. Yes. We have a clear strategy here. Looking at the CEO search, that's obviously a topic for the Supervisory Board and not for the Executive Board.
We are obviously aware that the supervisory board is working on a final solution for the CEO role. I'm sure that they, in a couple of months' time, will come up with a decision. In the meantime, Duncan and myself continue to drive as much as we can in this team to make sure that the strategy will continue to be implemented. Duncan, do you want to answer the questions around sales initiatives in North America?
Will do. Is that E&M International, but as Christina indicates, that's largely North America from a revenue domination. Securing the INEOS project was critical, and it's kept coming at a very good time for us, and that's already in execution as I mentioned, which is good. We introduced new management in there. Some people will know late last year, with a stronger focus on maintenance, and we've won a lot of nice mid-scale maintenance projects, which takes out some of the instability in the project environment in the midterm. Our P&G business, Procter & Gamble business is flourishing. There's a very high demand for that business, and that's continuing to go through and build through, which is very good. As is the demand for the infrastructure business within the U.S., which is coming from the Recovery Act that's being instigated across there.
We see good signs and very much in line with our strategy around de-emphasizing the project aspect of our North America business, investing more in maintenance and framework type contracts. Your second or fourth question, sorry, second for me, in oil and gas in half two, it's a very simple issue from an oil basis, a offshore basis, which is probably the point of the question there. We're good here by what we call POB, which is personnel on board. Throughout the pandemic, the number of POB spaces on the rigs has been reduced for social distancing reasons, et cetera. That has started now to increase as vaccinations come and we're far more able to control the issues.
We're already now starting to see rock-solid plans come in place for picking up maintenance work that couldn't be done in the last 12 months to be planned, materials ordered to be executed in half two. We're expecting a pickup to catch up from some of that delayed work. The gas market, that continues to flourish. Whether it's hydrogen, whether it's traditional gas areas, continues to be a strong market for us.
Thank you. Craig Abbott. Craig, you were on the list before, but the system was down again, so you might have to press zero and one again, then the line is free for you to ask your question. Same is true for Eric Lemarié. Eric, if you're still in the line, please press zero and one. Craig is back. Craig, it's your line.
Yeah, no worries.
The circumstances.
No worries. Well, my question on CEO success has been answered. Two others, one is maybe not an issue for Bilfinger, but we've seen some pretty significant supply chains disruptions in many industries as a number of suppliers have been caught out on capacity. I just wondered, are there any potential risk in Bilfinger's ability to source key products to execute on any of your orders in the coming months or quarters? Secondly, if you can maybe just give us an update please on the Hinkley Point project. Thank you.
I'll take these, Craig, apologies to everybody for the challenges we all get now and again in these more remote times. On supply chain, there are two aspects of this. Let's go really positive first. This is a great opportunity for Bilfinger because we will see supply chains shorten. There are opportunities here, not just in life sciences, but in other areas as certainly in our stronger European business, supply chains come back closer to Europe as there's less of a link towards some of the Far East suppliers that we've had. From our perspective, we have not seen any impact on our supply chains to date. There is challenges, we have not seen any to date. When it comes to Hinkley Point, on a very positive note on that basis, and linking in Brexit as well, we have delivered the first pipe across the channel.
We fabricated it, we've had it delivered, we've fabricated it, we've done all the quality packs, and it's now in the U.K. waiting installation. From an order perspective, as you know, last year we secured the substantial orders and now EDF are calling those down on us, and we are executing work. That will happen progressively over this year and years to come. We still expect peak revenue to be in 2022, 2023. We have no worries about work continuing to ramp up and having very good order coverage to cover that in the coming years. Continues as expected. Peak revenue 2022, 2023, as we've always said.
Okay. Thank you very much.
Next question comes from Eric Lemarié. Eric, the line is yours.
Yes, thank you. I've got some question, please. The first one, Duncan, you mentioned this better situation in the North, if I'm not wrong, because now you're more able to deal with all these social distancing issues. Regarding these constraints due to the pandemic, have you any idea when this restriction will be 100% lifted? Is my first question. On M&A, could you maybe be more specific on what type of targets you are looking for? Maybe what type of businesses or maybe what type of geographical zones? The last question on energy efficiency. You mentioned energy efficiency in your slide, I think it's slide number eight, do you have, or maybe can you share with us how much of your business is related today to energy efficiency? Thank you.
Okay. Thank you, Eric. I wish I could give you a specific date, like August the 16th or something like that, but we are seeing progressive reduction of restrictions, let's say that. We now have some rigs already back to full capacity with testing regimes. With the success of the vaccinations, we're expected to proceed very quickly. On the Norwegian side, actually, which is where we see the greater restrictions at the moment compared to the U.K. side, will be a little bit later in coming back. Yeah. That's more likely to be back end of the year, the U.K. side, more front end of half two. We expect to see that come through. We'll see a peak then to catch up, but then it will stabilize down to a more stable level going forward.
If you do remember in the slides, we did talk about consolidation of where our customers, as usual, are looking to how do they better utilize and be more efficient, and there's some very good opportunities at the moment which we're working on with our customers to deliver that with our combined service offering that we already have. I'll very briefly take the energy efficiency one. It's a very difficult one to say what do we have right now. What we do have is a range of significant opportunities in the energy transition area, where we are working with customers on either small scale technology or larger scale technology to reduce their carbon footprint as well as our own.
We're continuing to see that move very quickly forward in not just the hydrogen areas, but also carbon capture and battery technology and battery investment is a specific area that we've seen some great success in over recent months, where we are now probably the leading supplier in terms of the rush to the market to build battery plants, to build them, not the technology. To build them.
All right.
Christina.
Yeah. When it comes to M&A, I think first of all, looking from our front, given that we have a very strong market position in Europe, we are number one or number two in our regions. Obviously here we are looking for more bolt-on acquisitions in specific areas where we see that we can create additional synergies or growth. One example could be an acquisition in the Nordics, where we can strengthen our position beyond where we are today. It could also be biopharma. That is one of these markets that we see great opportunities to grow beyond the position we have today. In U.S., as Duncan mentioned, we are trying to get a bit more of a balanced portfolio, which means that we have less dependence on large projects and we are increasing our maintenance footprint in U.S.
In that process in U.S., it could be interesting for us to make one or another acquisition in the maintenance area to increase the speed in this. In addition to that, we also need to keep in mind that outside of Bilfinger, there are also things happening. In Europe right now, we see that a number of companies where we are partly meeting as competitors are for sale. Therefore, there will be a certain consolidation happening in Europe. Of course, we want to be in a position here to also be involved to see how we get out of this, and there might be one or another interesting target here for us. As always, the price has to be reasonable, and we want to have companies that are already profitable to be integrated in the Bilfinger group.
All right. Thank you.
If there are further questions, please press zero and one. Okay, there are no further questions as of now. As I said, please contact the IR department, especially in case there were technical problems also from your side. As of now, we conclude today's call. Thanks for participating. We wish you all the best, and we'll speak to you again latest in August. Bye and thank you.
