Good afternoon and warm welcome, ladies and gentlemen, to today's earnings call of MBB SE, following the publication of the financial figures for Q1 2025. The CIO, Torben Teichler, will speak in a moment and guide us through the presentation and the results. After the presentation, you have the opportunity to place your questions directly to him. We are looking forward to the presentation. Having said this, Mr. Teichler, the stage is yours.
Yeah, thank you very much and good afternoon, everyone. My name is Torben Teichler. I'm the CIO of MBB, and for those of you who maybe don't know me yet, I'm with the company for eight years now and have been on the board since 2021 and transitioned into the CFO role now in around about two months. In that capacity, I'll also take over investor relations from Constantin Mang, who together, as you know, with Jakob Ammer, has decided to not extend his contract after a really phenomenal run at the company over the past years. I'd like to take this opportunity again to really thank both for their great work and the achievement at MBB. It has really been an honor to work with both of them. We all wish both of them all the best. All right, let's jump right into it.
Let me start maybe with a quick recap of what makes MBB special for those of you, especially who are new to the company. MBB offers long-term succession solutions to sustainable Mittelstand companies. The way we do this is pretty unique, I would say. First of all, because we are a family business ourselves, we have two main shareholders who formed the company 30 years ago. Therefore, we share pretty much the same DNA with the companies we actually want to acquire. Secondly, we are fans of the capital market. You see us having an earnings call here today, but also three of our subsidiaries are stocklisted: Friedrich Vorwerk, Aumann, and Delignit. We, as a family business, have a long-term focus.
We do not buy for the short term; we buy for the long term, meaning we have no intention to sell when we buy, and we seek to develop and grow our companies in the long term. Last but not least, we focus on sustainable businesses, which does not mean that we are dogmatic or have a somewhat environmentalist agenda, but we simply believe in trends and the energy transition, for example, or IT security just offers enormous business potential, as we will see later in the presentation. Before we get to the Q1 figures, I would like to highlight one thing. We managed to finally enter the SDAX, both with Friedrich Vorwerk as well as MBB. We are really proud of that. For those who follow us for a bit longer, you know that has been one of our ambitions for quite some time.
Yeah, we're really proud and happy to have achieved that not only with one company, but even with two, pretty much at the same time here last Friday at MBB and on 17th of April with Vorwerk. We'll work hard to stay there. With that, let's move to our Q1 figures, which have really been a very good and nice start into the year. We had a strong first quarter, as you can see here, with 27% revenue growth to EUR 260 million and adjusted EBITDA growth, which stood at 32% at EUR 30 million adjusted EBITDA, and that allowed us to increase our margin even a little bit to 11.5%. Overall, I'd say a really good start into the year, and we'll elaborate on the drivers now in the next couple of slides.
If you look at the individual companies, and I'll give you an update on where we stand here. Yeah, maybe taking the segment view first here, the driver of this really good Q1 development was the service and infrastructure segment, with both Friedrich Vorwerk and DTS delivering excellent results, particularly looking here at the more than 100% increase in EBITDA. On the other hand, you see here the two other segments, technological applications and consumer goods, which, well, had a more humble start, let's say, into the year, however, pretty much as expected. I'll take you now into the individual segments and the companies with Friedrich Vorwerk here on the left side, clearly showing a very, very good start into the year with, or actually phenomenal start into the year with 73% year-on-year top-line growth to EUR 133 million and almost 14% EBITDA margin.
That was driven on the one hand by smooth execution and good progress on a number of projects, but particularly also ANOF, which I'm sure most of you have heard about. Secondly, we had generally mild weather conditions in the first quarter, and that tends to have a fairly strong impact on the output Friedrich Vorwerk can generate in the first quarter. The environment has just been very good for Friedrich Vorwerk here in the first quarter in terms of weather also and projects. The high output and utilization we had in the company allowed for a very strong EBITDA margin increase by around five percentage points to 13.7% in Q1. Looking ahead, you see the figure here. We have a well-filled order book of EUR 1.1 billion at the end of the first quarter.
There are also a couple of new projects, both from the electricity and the gas sector, which are providing additional tailwind. As you might have seen this morning, Friedrich Vorwerk announced the order win of section three of the Südlink electricity highway. That is a really large triple-digit million EUR project in which Friedrich Vorwerk has a 40% stake. It is not only, let's say, related to the electricity business, but also in the gas and the hydrogen segment. We really see good project activity with the company having just won the SER3 pipeline, which was announced, I think, two weeks ago, which is also a triple-digit million EUR project in which Friedrich Vorwerk has a large share. You see the dynamics are good on the electricity side, but also on the gas side and also hydrogen. There are a couple of projects in the market.
That is generally, of course, a very nice tailwind we have. The company has been very, well, was able to execute on these available projects, which gives us good visibility in general going forward. For 2025, Friedrich Vorwerk expects therefore to reach the upper end of its revenue guidance of EUR 540 million-EUR 570 million with an EBITDA margin of 16%-17%. Obviously, the strong Q1 is backing this up quite nicely. Turning to DTS, the company also had really a very nice start into the year with revenues growing by 20% to EUR 26 million and also with a decent EBITDA margin of 15%. We are really encouraged to see here that the company bounced back strongly after the rather muted second half of last year with demand recovering now and generally also the outlook on Q2 being rather positive.
That is really encouraging and good to see for us. Beyond that, own software sales growth has again supported profitability. DTS has just bought back the minority shares in ISL, the remaining minority shares in ISL, which provides a large part of that software development. I think that's also going to help us going forward. Looking ahead, yeah, for the whole year, we're rather optimistic on further growth and expect the focus on IT security in general, but also the formation of a new German government with its fiscal spending plans to provide positive tailwind for this year and beyond. To wrap it up, Friedrich Vorwerk and DTS have really been the growth engines this quarter. Generally, we expect them to contribute to our results also in the remainder of the year.
Turning to technological applications, the Q1, yeah, development has been rather soft at both Aumann and Delignit owing to the generally weaker demand in the automotive industry. Nevertheless, if we look at Aumann here on the left side, we managed to improve the adjusted EBITDA margin to around 11%. That was thanks to effective cost management and still solid order book. Revenues contracted 6%. That was pretty much expected. Order intake is still down year- on- year by around 30%. Nevertheless, this is the second quarter where we see a quarterly improvement on the order intake front. That is at least the first positive sign on the order front. Beyond that, there are a number of projects, especially in the next automation segment the company is working on. That focuses on industrial automation, aviation, life science, maybe some related sectors.
We hope the company can win and succeed there in order to diversify its markets further. With that, our view on 2025, our management view on 2025 is still that the guidance of EUR 210 million-EUR 230 million in revenues with an EBITDA margin of 8%-10% looks very well in reach for now. On the right side, Delignit has also seen a challenging environment with especially light commercial vehicle demand still mixed and OEM customers having rather volatile call-offs. Nevertheless, despite the revenue decline by 6%, the company has been very proactive in adjusting its cost base and managed to steer through this environment. There are also here a couple of interesting opportunities outside the automotive industry, particularly in the rail floor business. Management is also looking at one or the other M&A opportunity.
Overall, I would say the guidance for 2025 remains cautious at EUR 68 million in revenues and 6%-7% EBITDA. Yeah, we'll see what the second half of the year brings. At the moment, that's what we see. It's pretty much a development we'd expected by the beginning of the year. Turning to consumer goods, finally, we had a somewhat softer, let's say, consumer environment, which led to this moderate start into the year. At Hunke, we had temporarily lower productivity, which was majorly, however, due to the ramp-up of our new converting machinery. As you know, we've been investing at the company to increase our converting capacity, where we are able to convert the mother roll production out of the company into converted product.
That is slowly coming on stream, particularly in the second half of the year, and allows us to convert almost 100% of the mother roll we produce. That obviously is a tailwind for revenue and especially profitability as, well, converted product is obviously higher value than the rather commodity mother roll. The outlook for us here is that Hunke should do rather well in the second half again, while CT Formpolster, we've hopefully seen the bottom now in a rather, let's say, muted furniture market in general. We see slight improvements and hope to see further ones as we move along now through the year. To summarize, we've had really strong tailwind from the service and infrastructure segment with Friedrich Vorwerk and DTS benefiting from, well, healthy demand and good execution in general.
We expect that to continue also in the remainder of the year and to compensate for this rather modest development we have seen in the rest of the portfolio. Our guidance of EUR 1 billion-EUR 1.1 billion in revenues with an EBITDA margin of 11%-14%, let's say, cautiously reflects that dynamic and also the overall volatile macro environment we are currently seeing. Given that Q1 tends to be a seasonally weak quarter, generally, this fairly strong start into the year is clearly an encouraging data point for our guidance. Turning to our balance sheet, we have seen a seasonal change in working capital, primarily some investments, additional share buybacks compared to the end of Q4. Nonetheless, as you can see, our balance sheet remains rock solid with EUR 467 million in net cash at group level, of which EUR 262 million are attributable to the holding MBB SE.
That obviously provides us with ample room to maneuver in the current environment, but also to pursue M&A for the share buybacks and obviously pay a dividend. We have already announced that we will again propose an increase to our base dividend at the AGM at the end of June to EUR 1.11. That would be our 15th consecutive increase in the base dividend. Given the 30 years anniversary of MBB, we also intend to pay an extra dividend of EUR 2.22. That overall is then EUR 3.33 and amounts to almost EUR 18 million in dividends and comes on top of the share buyback program, which we just finished at the end of April, where we bought back MBB shares for around EUR 13 million at an average price of EUR 115 per share.
At least looking at the share price today, I think that has been a rather good deal. Last but not least, looking at our current valuation, we still, despite the good share price development, believe that MBB shares are attractively valued. As you can see here, our share and our listed subsidiaries plus the cash we have here at the holding level more than covers our current market cap. That obviously does not even attribute any value to really great companies such as DTS or Hunke, which you basically get for free at the moment. I hope I was able to give you a brief walk through our portfolio and Q1 figures here. I am happy to take your questions now.
Yes, thank you very much for your presentation and congratulations on your growing numbers. We will now move on to the Q&A session.
