Please go ahead, sir.
Guillaume Texier
Thank you. Hello, and good evening, everyone.
Thank you for joining us today for Rexel's second-quarter sales and first-half 2026 results call. As you saw in the figures that we just released, we delivered a strong performance in H1, both in sales and profitability.
Beyond the figures, what is particularly satisfactory for us is that those results are the direct results of actions we have taken over the last few years in terms of portfolio positioning, growth initiatives, and operational excellence actions. Laurent will cover the financials in detail.
Before that, I will highlight the strategic themes behind the numbers, and I will come back obviously with our concluding remarks and outlook. Shifting to slide 3, I will share the main messages that summarize our strong first-half performance.
First, sales reached almost €10 billion for the first time, and North America became our biggest platform in the second quarter. Second, same-day sales growth accelerated, up +6.7% in Q2.
This results from our targeted investment in high-growth segments that are becoming increasingly visible. Third, sales momentum, productivity, and disciplined execution are supporting margin progression, with adjusted EBITA up 40 bps at 6.2%, and non-adjusted EBITA margin at 6.4%, including the one-off gain on copper.
Lastly, free cash flow is robust for a first half at close to €250 million, confirming the cash-generating profile of the company. Moving to slide 4.
It's important to mention that we delivered those robust results in a low-cycle and volatile environment with limited visibility and geopolitical tension. Our sales growth in Q2 was above the high end of our guidance, supported by our positioning in high-growth segments, including data centers in North America and electrification in Europe.
More specifically, volumes were positive in all geographies for the first time since Q2 2023, and selling price increases were also positive in all regions, driven by raw materials and energy prices. On profitability, we reached a 6.2% adjusted EBITA margin despite negative product and market mix effects.
This performance was supported by higher volumes, increased selling prices that more than offset opex inflation, and record productivity of 4% thanks to our optimization programs and AI transformation. Moving to slide 5, focusing on electrification in Europe, a major growth driver in the quarter.
The external context is clearly supportive. Successive heatwaves are increasing the need for cooling solutions, while energy price volatility and energy security concerns are driving customers to invest in efficiency, self-generation, and energy independence.
This is visible across our HVAC, solar, and EV charging businesses. These categories represent 22% of our European sales and grew by a strong 15% in Q2.
France and the Netherlands, for example, benefited from the growing demand in HVAC. Switzerland, the Netherlands, and France saw support from EV-related infrastructure, while solar boosted several markets, including Austria, Ireland, and Belgium.
Moving to slide 6 and the data center opportunity in North America, the other major growth pillar in the quarter. This trend is linked to major structural needs around AI, cloud infrastructure, power availability, cooling, connectivity, and reliability.
These projects require complex electrical capabilities, strong execution, and close customer relationships. We are moving up the value chain and are increasingly supporting our customers with technical capabilities and solutions.
In the US, our data center activity grew more than 80% in the first half, supported by large project execution, notably in the Mountain Plains area and Southeast regions. Order intake remains robust, with data centers now representing around 25% of our backlog.
In this vertical, we continue to gain market share thanks to our service capabilities and execution reputation. We now anticipate that this segment, which accounts today for 9% of our US sales, will grow above 50% in 2026 versus our initial objective of above 20%.
In Canada, we have also built strong credibility from scratch in less than a year, reaching a 7% exposure to the data center segment. We are now starting to expand into adjacent areas such as white rooms, fiber optics, and cooling systems.
Finally, our latest acquisition, Techno-Contact 360, also brings additional solution design expertise. Moving to slide 7, on M&A, we had a busy first part of the year with three acquisitions executed.
We are acquiring capabilities, technical expertise, and increased exposure to attractive end markets where Rexel can create additional value. The three transactions completed this year will be adding €400 million of sales and strengthen our exposure to industrial automation, advanced services, and data center-related applications.
Revere Electrical Supply enhances our position in industrial automation and expands our partnership with Rockwell Automation to the attractive Midwest region. Techno-Contact 360 strengthens our Canadian data center capabilities and supports our move into higher value-added services.
Dee Electronics, our latest acquisition, closed on July 10th, adds advanced manufacturing capabilities, including cable assemblies and panel solutions for leading OEMs, here again with a sizable exposure to data center. Together, these acquisitions increase the share of the portfolio exposed to secular growth trends and supports our medium-term ambition.
With that strategic context in mind, I will now hand over to Laurent, who will go through the financial review.
Laurent Delabarre
Thank you, Guillaume, and good evening, everyone. On slide 9, you can see our momentum improved sequentially.
We moved from +3.4% in Q1 '26 to +6.7% in Q2 '26, with a good balance between volume and price contributions. First, volumes contribute for 3.1% in the quarter, with all region in positive territory for the first time since Q2 '23.
Second, selling price contribute positively for 3.6%, including non-cable pricing for 1.4% and cable pricing for +2.2%, reflecting the higher copper price. Briefly, on our two main geographies that I will highlight in the next two slides: North America, representing 47% of sales, accelerated and was up 7.8%.
Europe, accounting for 46% of sales, posted robust growth of 2.4%, significantly higher than Q1. Focusing on Asia-Pacific, which accounts for 7% of group revenue and grew by 17%, sales in China and India grew by +9% and +31% respectively, supported by industrial automation activity.
In Australia, sales growth further accelerated in the quarter at +22%, boosted by solar activity. I'll now go more detail on North America and Europe in the next slides.
Starting with North America on slide 10, project activity, especially in data centers and industrial automation, was the main driver of the sales acceleration. Digital adoption continued to progress rapidly, almost up 400 basis points to 27% of sales, supported by new quote and order entry tools.
This is important because it strengthens customer stickiness while also improving productivity. In the United States, same-day sales growth reached 7.8% in the second quarter.
The performance was driven by very strong data center activity, up more than 100%, continued growth in industrial automation, up 15%, and positive trends in markets such as the space industry, hospitals, and water/wastewaters. Canada also delivered solid growth, supported by data center activity and strong performance of our latest acquisitions.
As presented on slide 11, Europe showed a clear sequential improvement in the second quarter, up +4.4%, driven by double-digit growth in energy transition solutions. More specifically, France was notably supported by HVAC, both in the commercial and residential segments.
Benelux benefited from HVAC and EV solutions in the Netherlands, and solar in Belgium. The DACH region improved sequentially, notably supported by the solar activity, significantly growing in Austria and returning to close to break-even in Germany.
In addition, Sweden also delivered growth, thanks to good strategic execution and improvement in the residential market. Lastly, the UK remains more challenging, but the strong growth in Ireland helped to partly offset that weakness.
Moving now to the half-year picture, I start on slide 12 with the sales bridge. We delivered H1 '26 sales of almost €10 billion, up +2.2% on a reported basis.
The organic performance was the main driver, with same-day sales growth up +5.1%. Volumes contribute for 1.9%, and pricing added +1.3% in non-cable and +2% in cable.
M&A also contributed meaningfully, with acquisition added +1.4%. These positive elements were mitigated by a -2.6% currency effect that will reverse in H2, and a -1.3% impact from the disposal of our activity in Finland, completed in Q3 '25.
Let's now move to profitability and margin performance. On slide 13, we bridge our adjusted EBITA margin, with the improvement mainly driven by operating leverage and well-executed action plans.
Adjusted EBITA margin increased 40 basis points at 6.2% despite a more competitive environment, negative product mix, and investment for growth. First, scope and FX were positive, contributing +11 basis points from good portfolio management.
Second, you see that operating leverage contributed 17 basis points, mainly driven by volume growth in North America and APAC, as European volumes turned positive in Q2 '26 only. Third, the delta inflation, as the gap between selling price increase and opex inflation, returned to positive territory with a +6 basis point effect, mainly driven by Europe.
Fourth, action plans contribute for 22 basis points to the adjusted EBITA, including a record level of 4% productivity from the gap between sales volume growth and reduced average FTEs combined with other cost initiatives. By geography, the progression was mainly driven by Europe and Asia-Pacific.
On slide 14, we look at the bottom line part of our P&L, with a zoom on other income and expense, financial expense, tax rate, and recurring net income. Other income and expense stood at -€8 million, mainly related to acquisition and integration cost, as well as restructuring, notably in Europe.
We anticipate to be closer to €35 million in full-year '26 as we'll further integrate acquisition and execute turnarounds in some countries. Financial expense stood at €113 million, slightly above last year, reflecting lower cost of debt and higher gross debt.
It includes €37 million of interest on lease liabilities. For '26, we anticipate financial expense of circa €230 million, including €75 million of interest on lease liabilities and €155 million on pure financial expense, excluding one-offs.
This assumes current interest rate conditions remain unchanged. Our income tax rate stood at 30.5% due to the impact of the exceptional tax in France.
Excluding that, the normative tax rate stand at circa 27%. As a result, our recurring net income stood at €347 million, a double-digit growth of 13%.
Moving to slide 15, we generate gross cash flow before interest and tax, reaching €247 million, implying a free cash flow conversion rate of 37%. Trade working capital stood at 16.3% versus 15.9% last year, mostly coming from strong sales growth acceleration in Q2 '26.
It's worth noting the good management of inventory and receivable with lower days. Lastly, the capex to sales ratio stood at 0.7%, similar to last year.
As shown on the next slide, on slide 16, our capital allocation is well-balanced between acquisitions and return to shareholders. Overall, our net debt increased by €390 million, mainly resulting from two factors: first, €398 million cash-out for net financial investment, mainly from the acquisition of Revere in the US, TC360 in Canada mentioned earlier by Guillaume; second, the dividend payment relating to the 2020 to 2025 for €353 million, corresponding to €1.2 per share.
All this leads to a net debt of €3.3 billion and an indebtness ratio of 2.4 times. We also continue to actively manage our financial structure.
As shown on slide 17, we extended our debt maturity profile through a €125 million Schuldschein with 2029 and 2031 maturities, and successfully issued a first convertible bond in May for €400 million with very attractive financial terms, namely 1% coupon and a conversion rate above €50. If you also add in the €1.8 billion liquidity, we have the financial flexibility to execute our strategy and fund growth opportunities.
I will now hand back to Guillaume for the outlook and guidance.
Guillaume Texier
Thank you, Laurent. Let me now turn to the outlook on slide 19 and share the reasons behind the 2026 guidance upgrade that you saw in our press release.
First, we had a strong start to the year, both in terms of growth momentum and disciplined execution. Second, we are capturing secular growth trends across a more diversified portfolio, particularly in data centers, electrification, and industrial automation.
Third, our record backlog improves the visibility of our activity for the remainder of the year. At the same time, we keep monitoring potential risks.
Macroeconomic and geopolitical environment are still uncertain, with energy price volatility. We are also operating in a competitive market, and maintaining and progressing gross margin is a constant battle.
On slide 20, let's look maybe at our order backlog in North America, which has reached record levels. We have crossed $2 billion in the US and CAD 1 billion in Canada.
In the US, our backlog now represents about 3.1 months of sales. You can see the trajectory in the charts since 2022.
After a relatively steady phase, we are clearly moving up from $1.8 billion in Q1 to $2.2 billion in Q2 2026, a sequential increase of +25%, mainly driven by several projects in data centers and in the space industry. In Canada, the momentum is even stronger.
The backlog covers roughly 5.5 months of sales with a steady climb since 2024 and a sequential increase of +30% in Q2, mainly driven by a large contract won by TC360 thanks to the increased execution capability brought by the Rexel team. This good start of the year leads us to increase slightly our guidance despite the still uncertain conditions, and I'm now on slide 21.
We now expect same-day sales growth of around 5%, compared to the previous range of between 3% to 5%. We expect current adjusted EBITA margin of at least 6.2%, compared to circa 6.2% initially, and free cash flow conversion still above 65%.
Let me now finish with two slides projecting ourselves beyond 2026 and using the H1 results to illustrate the key levers that make us confident in our capacity to reach our medium-term sales growth guidance. The chart on this slide illustrates how our portfolio is built, and I would stress that these splits are indicative, meant to show the balance of our exposure rather than a precise segmentation.
Today, roughly two-thirds of our sales are exposed to the traditional construction and economic cycles, split between renovation and new build in Europe and in North America. This gives us a solid, well-diversified base that would also benefit from any economic recovery.
The remaining third of our sales is exposed to structural megatrends such as AI and data infrastructure, the energy transition, and industrial modernization. As illustrated in recent financial presentations, these markets grow structurally faster than the underlying construction cycle, and this is where our targeted investments are increasingly visible.
What is also interesting is how independent from each other those trends are. You saw in the first half that our good results didn't come only from data centers, but also from energy transition-related trends in Europe and industrial automation throughout the world.
This is the kind of balance we have been trying to build over the years and which is now delivering. Now on the profitability side, and I know that the markets are very focused on our mid-term goals of 7% EBITA profitability, let me try to share with you on slide 23 why we are increasingly confident in our capacity to reach it.
Our Accelerate '28 strategic plan works as a roadmap. As we advance and execute it, we progressively validate the different pillars.
Please note that the figures on this symbolic bridge are illustrative. They are meant to size the potential of each lever and to explain our reasoning, not to give precise guidance brick by brick, as not all will materialize at the same speed.
Let me walk you through the main pillars, starting with the drop-through on additional growth. This growth will come both from cyclical recovery and accelerating trends.
There are many uncertainties here, but we know that drop-through on additional sales is usually around 5 to 10 bps by additional growth percent on volume. We see also on this year's results, for example, the order of magnitude of how much electrification trends can bring to the top line.
Second, productivity and automation. Salaries and benefits represent around 10% of our sales, and our current initiatives point to a double-digit additional productivity potential.
This is where AI is a very significant opportunity for us. That said, this is a calculation one should be very cautious about for many reasons: firstly, because this is only an initial evaluation; secondly, because theoretical productivity doesn't always translate into real productivity, especially in parts of our organization with small groups of people; and thirdly, because in a competitive world where every competitor is working on AI, parts of the benefits may be given back to the customer in price.
You get the idea, which is that the potential of those initiatives is quite sizable. Third, the turnaround of our least profitable countries.
Our four least profitable countries represents around 15% of sales, and we think that there is a triple-digit bps profitability improvement potential here, and actually, in H1, we have started to deliver that. Here again, many caveats, the first one being about execution risks, obviously, and the second one about double counting with other pillars.
Fourth, operational excellence, several programs launched under Accelerate '28 in pricing, supply chain, procurement, product mix carry overall a double-digit bps global EBITA improvement potential. Finally, portfolio management, as a back-of-the-envelope calculation, adding around 10% of acquired sales with a 200 bps accretive effect, for example, from synergies, would generate roughly 20 bps of EBITA.
Once again, the idea of walking you through this bridge is not to give you guidance, but rather to share with you two main things: first of all, there are many initiatives taking place; some will succeed beyond our expectations, and some will, to the opposite, not realize their full potential, but the fact that there are so many action plans is giving a good degree of comfort; and obviously, the second takeaway is that the sum of all the potential is higher than 80 bps. Even if there are double countings, probably overoptimistic assessments, and bumps in the road, we feel relatively safe that the path we are taking is leading us to our goals.
That concludes today's presentation. In summary, H1 2026 demonstrates that Rexel is delivering profitable growth, transforming its portfolio, and improving visibility.
We are very pleased with the performance, but we also see it as further evidence that our transformation is gaining momentum. Thank you.
Laurent and I are now happy to take your questions.
Operator
Thank you, sir. We will now begin the question-and-answer session.
Anyone who wishes to ask a question may press * and 1 on their touchtone telephone. To remove your question, please press * and 2.
Please pick up the receiver when asking questions. First question comes from Martin Wilkie of Citi.
Martin Wilkie
Thank you. Good evening, it's Martin at Citi.
Just had a couple of questions on your revenue guidance. You've obviously took the guidance to the upper end of the prior range, but it was also a very strong Q2.
If you could just talk a little bit about how you see some of the benefits you had in the second quarter continuing, particularly electrification in Europe, obviously benefited from energy prices and presumably investment in solar, EV, these kind of things. Does that continue into the second half, or was that really sort of mainly boosting the second quarter?
In terms of pricing, that accelerated quite a decent amount in the quarter. Is most of the pricing from a sequential perspective now done, or are you seeing signals that pricing could continue to go up over the course of the year?
Thank you.
Guillaume Texier
Good question, Martin. On the electrification trends in Europe, it's difficult to predict with certainty.
It was a little bit unexpected. The turn of events triggered a high level of interest in electrification, and I can tell that this level of interest continues in July.
This is the first thing I would share with you. Obviously, energy prices were a trigger.
Energy prices are still relatively high with a lot of geopolitical uncertainties, we continue to see a high level of interest into that. One thing on which I'm a little bit less sure for H2 is obviously the high level of interest that we had in June in particular to air conditioning technologies, it's not a big proportion of our sales, it's around 2% of our sales in Europe, but that being said, there was a high level of interest due to the heatwave in Europe.
It seems like we are going to continue to have a hot summer, we may continue to see some of that, but it's not a given, and it's really weather-dependent. For the electrification trends, at this stage, we continue to see a high level of interest.
I have to say, many customers I'm talking to are realizing that it's not just adapting to the short-term energy variations, but it's also making sure that they build an energy supply source which is resilient and risk-free. I think probably the market there is a little bit of structural in there, but obviously if the oil price drops down, we may see a little bit of a slowdown here, but at this stage, I don't see that.
When it comes to pricing, we have a few price increases happening at the beginning of H2. I don't think it's going to be of the order of magnitude in terms of sequential pricing of what we have seen in H1, but that being said, we have a little bit of sequential pricing coming in.
That's what I would say.
Martin Wilkie
Great. Thank you very much.
Operator
The next question, sir, is from Akash Gupta of J.P.
Akash Gupta
Morgan. Hi, Guillaume and Laurent.
I have a question on margin. If we look at historically in normal years, we have a seasonality of H2 margins being ahead of H1 by around 40 to 50 and sometimes 60 basis points.
You have not given a precise margin guidance and you're guiding for at least 6.2%, but maybe if you can talk about some of the margin bridge and anything that we should be expecting this year that might be different than what we have seen in normal years in the past. Thank you.
Guillaume Texier
Laurent, do you want to answer this one, or? We we we guide on
Laurent Delabarre
on the margin side there is two components. The first one is the is the is the gross margin, where we in the first half, we we have we are globally flat with two balancing acts: a bit of pressure on the commercial margin that will continue all over the year because of product mix, and we have also some some inflation, as we just said, that will not be there in the second half.
On the margin side, we'll have a bit more pressure on the second half than in the in the first half. In the opex side, in the first half, we are benefiting from the carryover effect of of last year action plan, which which help us, which will be less there in the second half.
Globally this year, we have also a bit more inflation globally on the opex. That's why today we have a kind of H2 that that has not the usual drop-through that you can that you can expect.
Guillaume Texier
You're right, Akash. Like-for-like, H2 margins are usually higher, and particularly this year, where we have more working days in H2.
That's the basics. Laurent is right, there continues to be a little bit of pressure on gross margin, which we are taking into account, a little bit also of timing effect in the transformation plans.
It explains a little bit our caution at the bottom end of the guidance. Obviously we are shooting for higher than that.
Akash Gupta
Thank you. Just a more strategic question on HVAC.
You had a very strong growth in Netherlands and France. How easy it is to expand this business in other countries where you are not having this right now?
Is this something that can be done organically, or do you need more like an acquisition to expand HVAC in other European countries? Thank you.
Guillaume Texier
Look, in France, it was done almost organically, but it was done over 20 years. I think it would come with an acquisition if we were to do it somewhere else.
Let me remind you why we picked France and the Netherlands to be a little bit more exposed to HVAC. It's for two reasons.
Those are countries where the two trades, HVAC installers, plumbers, let's put it this way, and electrical installers, are converging more and more. We see common customers, there is a demand for one-stop shop, and that's the reason why we invested in those two countries.
The second thing is in those two countries, there is a strong trend in the direction of electrification of heating through heat pumps for different reasons: availability of electricity in France, not availability of gas in the Netherlands. We felt that the combination of those two things made it value-creative for a company like Rexel to invest in that.
Now is it our plan to invest in all European countries? No, I don't think so.
We may look at opportunities, but really strategically and always looking at what is the level of synergy and what is the level of growth above the cyclical market in the countries where we would be interested. That's a little bit the answer for me.
We will continue to be selective.
Akash Gupta
Thank you.
Operator
The next question is from Jonathan Mounsey of BNP Paribas.
Jonathan Mounsey
Hi. Thanks for letting me ask a question.
A couple, if I may. You've been mentioning HVAC and obviously the energy transition technologies.
I think all of us in Europe during this quarter have probably looked to maybe buy some HVAC or know someone that has. It's basically all out of stock.
I guess you didn't know there was going to be this heatwave. I just wonder, you've had this amazing boom in demand.
Did you actually have any inventory? Is there likely to be a hangover in Q3 just because even if demand is still there, you basically sold all of your inventory during Q2, I just wonder whether there might be a bit of a bump there.
On APAC Australia, obviously demand incredibly strong, I think from memory 22% growth, boosted by solar, and I think that's government initiatives supporting that. What's the latest news on that?
How do you feel that may play out? Where's that support to end,
Guillaume Texier
where it's to end? Two good questions.
On HVAC and specifically on air conditioning because there was a strong demand in France and in the Netherlands for air conditioning, we happened for non-particularly strategic reasons, but mostly because of correction of past situations, we happened to have a high level of inventory in the Netherlands. At this stage, I don't know of any particular shortage in France or in the Netherlands.
We have replenished our inventory, and we are not going to face shortages in H2 if there is additional demand. Now if there are five heatwaves between now and the end of the summer, it may become an issue, but it's going to be, from a business perspective, it's going to be a good issue.
At this stage, I think we are in pretty good shape, not better, but not worse than any competitor. Now when it comes to Australia specifically, because I think the rest of the growth in APAC is mostly China and India on industrial automation, but you're right, in Australia, part of the growth, a small part of the growth, is that the market is doing a little bit better outside of PV, but a big part of the growth is PV and batteries.
There has been a programmed, planned reduction of incentives in Australia. That being said, I think the reduction of the incentives was two months ago, I think?
In May, yeah.
Guillaume Texier
In May. We have not seen such a sharp slowdown in PV.
I think it's a little bit the same answer I was making to Martin about electrification. Australia understands that overall, they are super dependent on oil, specifically oil coming from the Middle East.
The Middle East conflict is not finished, and so from a risk management perspective, it continues to make sense, even with slightly lower incentives, which are still at a good level, to invest in PV and batteries. We continue to see a good level of interest plateauing a little bit, but that being said, still much higher than one year ago.
I'm not able to predict exactly what's going to happen in the future, but it feels like many economic players or residential homeowners in Australia are continuing to be very interested in photovoltaic technologies.
Jonathan Mounsey
Thank you.
Operator
The next question comes from Max Yates of Morgan Stanley.
Max Yates
Thank you, and good evening. I just wanted to ask about the sales growth guidance and the sort of step-up of, I guess, 100 basis points from sort of 4% to 5%.
It looks like you can get kind of most of that from the step-up in your data center guidance, I guess I was just kind of curious around some of the parameters that have led you to upgrade the guidance. I remember you talked about kind of copper prices of $11,000 within your prior guidance.
Has that changed? You used to quite helpfully kind of break it out between kind of volumes, copper, and non-cable price.
Just trying to understand kind of how you think about those moving parts as we sit here today. Ultimately, was it just data centers or something else that led to the guidance upgrade today?
Guillaume Texier
Yeah. No, I think there are many things playing into the guidance upgrade.
On the positive side, there is obviously the data center business, and you have seen the backlog, we feel very comfortable with what we are going to deliver between now and the end of the year. I'm not saying it's in the pocket, but frankly, it's quite secure.
Then the second thing is on the full-year basis, there is a little bit of electrification effect in Europe, and there may continue to be a little bit of a tail end of an electrification effect in Europe, so that's a second part. Thirdly, you're right that there is a little bit of pricing compared to the initial guidance in copper, that's contributing also.
On the opposite side, there are a few negatives. The few negatives are that the economy in Europe is not doing better, and to the opposite, you remember that in the initial guidance, we had integrated a progressive recovery of the economy in Europe.
Given the geopolitical situation, given inflation, given interest rates, I'm not planning on that anymore. In the US, there is also a little bit of question mark about the economic prospects.
If you look at the Q2 sales, if you subtract data centers from North America or the US, and I'm pretty sure that you have done the math, and if you subtract price, you will see that we are probably slightly negative in volume in the US despite automation being up by double digit. The real economy in the US is not doing that crazily well.
There may be a little bit of the fact that electrical installers are mostly focused on data centers, the capability to install other things is reducing. That being said, it leads us to be a little bit more cautious than what we were at the beginning of the year on the rest of the US economy beyond data centers and industrial automation.
That's a little bit how the guidance is made. You're right that if I take only data centers and copper and electrification, I would get to a higher result than the around 5%, but there is also a level of caution and uncertainty around the macroeconomy.
Max Yates
Okay. Given you answered my other question, I'll ask a slightly different one.
Just the one-off on copper that you talk about, is that inventory revaluation? I guess what I was trying to understand, if you go back to '21 and '22, I think you talked about quite sizable inventory revaluation then, and those were kind of included in the underlying numbers, I guess I'm just trying to understand exactly what was that 21 million in copper impact?
Guillaume Texier
I'm not sure I completely understand the question, but let me remind you how it works, which is that the one-off specifically on copper is the difference between the 6.2% adjusted EBITA margin and the 6.4% that we usually don't report, I mean it's written somewhere in the in the press release, but we usually don't report on its first page. The difference between the 6.2% and the 6.4% is the one-off on copper.
In times in 2021 and 2022, not only I mean there was a little bit of inflation on copper, but more importantly, there was inflation on the rest of the price of products. When there is inflation and therefore, let's call it inventory one-off effects on the rest, which is not copper, we take it in the EBITA, percentage, the adjusted EBITA margin.
That's, that's the way it has been built with Rexel. It's a little bit strange to understand, but copper is outside of the adjusted, and the rest of inflation is within the adjusted.
That's the reason why in 2021 and 2022, we disclose to the market not only the adjusted, but the adjusted without one-offs also. I don't know if I'm clear.
Max Yates
No, that's fair. I was just wondering whether there was any non-copper inventory revaluation in the quarter.
Guillaume Texier
There was a little bit in H1, but relatively limited. Remember that there were also the same kind of limited one-offs last year in North America because of the tariff, on a like-for-like basis, the evolution is a little bit positive, but not that meaningful, or else we would have restated it in one-offs.
Max Yates
That makes perfect sense. Thank you.
Operator
The next question is from Aron Ceccarelli of Bank of America.
Aron Ceccarelli
Hello, hi, good evening. Thanks for taking my questions.
The first one is a follow-up on what you just talked about on the North America growth ex data center and industrial automation. Perhaps could you expand a little bit on the verticals that actually deteriorated a bit, and would like to understand if the deterioration happened really at the beginning of the quarter, towards the end of the quarter, please?
Guillaume Texier
It's difficult to enter into this degree of this degree of detail. In in terms of I mean we we have seen I don't I don't know the answer to that, Laurent.
Do you know?
Laurent Delabarre
We pointed out the one that are growing significantly and the one which were a bit shier are quite diverse. For example, we are a bit low in the automotive industry, for example, in some region.
That's one example, yeah.
Guillaume Texier
I wouldn't point at a specific vertical. Overall, growth is still positive.
It's volume growth that we are talking about, which would be slightly negative. I remember that last year, we had a strong activity in retail, and so maybe there is a negative here.
The office space is still not super active. Nothing very dramatic apart from what Laurent was mentioning.
Laurent Delabarre
No, no, that's it, yeah.
Guillaume Texier
Yeah.
Aron Ceccarelli
Understood. Thank you.
The other question is on Europe. I understand probably it's not easy to strip out the impact from energy transition products, but I wanted to have a rough idea of how Europe sequentially did on residential.
Did it deteriorate further? Did it improve, any stabilization?
Guillaume Texier
No.
Laurent Delabarre
The residential was mostly helped by the electrification as we are working mostly in Europe in the renovation side. When outside of renovation, the new construction is still negative, and
Guillaume Texier
we don't see any structural improvement overall, but we benefit strongly from this electrification trend that is flowing into the construction and mostly in residential. I would say, apart from that, if we try to do the math, we had a growth of residential overall of what, 7%, something like that?
Out of that, we have 20% of Europe which is the electrification energy transition-related businesses, which are growing double-digit, a little bit more than double-digit, there may be a 3% to 4% contribution of that. There is growth in the residential space, I think, in H1, mostly price, but a little bit of volume, too.
Aron Ceccarelli
Got it. Very helpful.

The next question is from Daniela Costa of Goldman Sachs.
Daniela Costa
Hi, good afternoon. Thank you for taking my questions.
I wanted to ask two things. First, maybe can you give an update on Germany and UK margins and how are they trending?
I guess Germany has turned positive now. Is this past break-even?
Then I'll ask the second question.
Guillaume Texier
The quick answer is yes. It's doing well.
In both countries, we are progressing triple-digit in bps in profitability with good evolutions on margin. Our actions are paying off.
I'm not declaring victory here because it's a long-term effort and there may be a little bit of circumstantial, but that being said, yes, it's contributing importantly to our profitability improvement in Europe in this quarter. This is the reason why we illustrated it in the bridge that we put in the last slide.
It's absolutely doing according to plan, let's put it this way.
Daniela Costa
Thank you. Then just as we start to see some announcements like in France, we saw the announcements of SoftBank and data center announcements coming to Europe, is there any reason why we should think the way that you might or might not benefit from data centers in Europe is different to the US?
Is there any structural difference between the businesses, or should we assume a sort of similar trajectory as we start to see this announcement coming out?
Guillaume Texier
I think overall, we are less exposed to very large projects in Europe than we are in the US. That's by the way the industry is organized, but large or super large projects are usually a little bit less distributed in Europe than they are in the US.
It would be a long story to explain why, but that's a little bit the case. That being said, what we have seen in the US is that there are the hyperscale data centers, but there are also the colocation data centers, the edge data centers, where the opportunity for distribution, including in the white space, is much higher.
I think overall the answer to your question is you're going to see a little bit of less of an exposure to data centers in Europe, but you're still going to see an exposure.
Daniela Costa
Got it. Thank you very much.
Operator
The next question is from Andre Kukhnin of UBS.
Andre Kukhnin
Hey, good afternoon, good evening. Thank you very much for taking my questions.
Can I start with one on North America margins, the year-on-year kind of flattish evolution with 6% growth, where you talked about normally that should generate some operational gearing. Is that the effect of now having larger projects and hence maybe a bit of margin dilution from that, or is there anything else for us to bear in mind there?
Guillaume Texier
Good question. There are three effects there that I will mention.
The first one is you're right, I think the very large projects, including data centers, are probably slightly dilutive, not very much, on EBITA, not much because we are quite selective in general and able to compensate the low gross margin through optimized opex, but a little bit. There is a little bit of that.
There is a little bit of investment in the future, too. We are leading transformation programs quite ambitious to optimize our service and cost, to build AI capabilities, and to position ourselves even better on those fast-growing verticals, so that's consuming a little bit of opex on a temporary basis.
Last but not least, we have seen price inflation, that's true, but we have also seen inflation in opex, in medical, benefits, transportation. We were overall able to serve higher volumes with stable headcount in North America, but the decrease of opex in percentage of sales was not as high as what a perfect sales drop-through situation would have led to, I don't know if I'm clear.
This is because of the inflationary environment, which on the other side creates over-positive effects in the rest of the P&L. I think those are the three reasons why the EBITA margin evolution was not as high as people would have calculated from an outside-in perspective.
Andre Kukhnin
That's really helpful. Thank you.
Second question I wanted to ask, is it possible to take out just purely that June HVAC boom thanks to the early heatwaves out of Europe performance? Would you be able to say what that Europe growth would be if you just take that one particular piece out?
Guillaume Texier
I didn't do the calculation. Laurent, who is super strong, will do it immediately in 5 seconds: 4, 3, 2, 1.
Andre Kukhnin
No pressure, Laurent. I would start
Guillaume Texier
by saying it's not super major. It's helpful, but it doesn't completely change the directional picture in Europe.
No, unfortunately, Laurent will have to come back to you. Inside other segment, heat pump and so on, structural things.
Look, no, it's not major, it's less than 1%. It's less than even 0.5%, I think.
Andre Kukhnin
So 2.3% could have been, yeah.
Guillaume Texier
It could have been
Andre Kukhnin
1.5% or 1.something,
Guillaume Texier
yeah, something like that.
Andre Kukhnin
Great. If I may, just one more on data centers.
What is your assumption now for the full-year growth for this segment within the 5% group guidance?
Guillaume Texier
I think I said it at some point, but I said it quickly. We said more than 50% growth of data centers,
Andre Kukhnin
that
Guillaume Texier
data center vertical. Initially we were starting the year saying it would be more than 20%.
We are now planning for more than 50%.
Andre Kukhnin
Thank you very much.
Operator
The next question is from William Mackie of Kepler Cheuvreux.
William Mackie
Good evening. Thank you for taking my questions also.
A couple, I just wanted to go through the bridge on profitability and give you a chance to call these out. When I look at the delta on inflation point, I think in the second half of last year, it was somewhat of a challenge.
I think there was a headwind of about 19 basis points, and now you've managed to get that to 6 basis points. Could you talk through or throw some color on how you see the price-cost evolution into the second half of the year given perhaps some of the pricing and volume momentum you've achieved as you've gone through the second quarter?
Guillaume Texier
Look, in terms of price-cost delta, I'm a little bit cautious about that for the rest of the year because we are also seeing that inflation of our cost when it comes to transportation, when it comes to medicals, benefits, and salaries, there is a lag effect from time to time. I think the best assumption for us is to keep it neutral basically.
We have taken a little bit of a head start, and we are quite proud of what we have done overall. We have tightened cost everywhere we could.
We have renegotiated. We have also passed through fuel surcharges in the places where it was justified by the fuel evolution.
I think we have done quite a good job compared to our initial expectation, which was to be slightly dilutive. That being said, for the rest of the year, I'm a little bit cautious, and I would say neutral.
William Mackie
Thank you. Building on the discussion around the bridge, your action plans are continuing to make a good contribution specifically, but again, slowed down a little, I think, half-on-half or H2 on H1.
Could you talk a little bit about how you see the action plans evolving? I think you redefined the restructuring charges or the one-time charges for the full year now in your earlier statements.
How are we thinking about action plans evolving and the drop-through into the second half of the year, please?
Guillaume Texier
You remember that there were many action plans initiated during last year, and we knew that the benefits of those action plans would be front-end loaded. That's a little bit what it is.
That being said, we are relaunching in a certain number of countries some additional action plans. Because of that, I think you're going to have a contribution of the action plans which is going to be maybe slightly lower, but not that much lower, but with a different mix.
There's going to be less carryover from last year and a little bit more of new action plans. That's also the reason why Laurent flagged the fact that we would probably have non-operating costs a little bit higher in H2 than what we had in H1.
I think that's how you should see it: a little bit less contribution, but not super material compared to H1.
William Mackie
Super, thank you, Guillaume. If you bear with me, last question on pricing relates to maybe some additional color on how you saw the price evolution around some of your major categories.
You've defined cable as we have done historically, but I'm thinking more like lighting or low-voltage product or some of the specific electrification areas, which, EV, for example, that was particularly deflationary historically. Some of the trends around pricing around categories, please.
Guillaume Texier
PV is starting to be positive again. For the other categories, basically it's relatively homogeneous with price increases across the board between 0 and 5% effect.
Lighting is a little bit weaker, but positive. That's what I would say.
William Mackie
It's very helpful. Thank you very much.
Operator
The final question, sir, is from Eric Lemarié of CIC Market Solutions.
Eric Lemarié
Yes, good evening. Thanks.
I've got three questions, please. The first on M&A, I was looking to your slide on M&A, and I was wondering whether it was me or are you accelerating in services?
When I look at Dee Electronics in particular, it looks like it's very exposed to services. I was wondering if we should expect a further acceleration in that field.
Second question on industrial automation, you mentioned a 15% sequential growth in Q2 if I'm not wrong, but what about year-on-year growth? On datacom, maybe you can share with us the performance of Telco or maybe the datacom business you are in the US in Q2.
Thank you.
Guillaume Texier
Yeah. On M&A, it's true that we have a specific focus on services, not on services independently of products.
If you look at Dee Electronics, they are selling wire harnesses, for example, not to the automotive industry, but to professional OEMs, including in the data center cooling area. We are always more interested in those companies which add specific value to their customers through services.
It's one of the main pillars of our Accelerate '28 programs. We strongly feel that to continue to be profitable and to increase our level of profitability, we need to add more value.
We are pushing that organically, but whenever we can, we also acquire companies having this particular capability, and we will continue to do that. Now that being said, is it going to be a pure new services pillar disconnected from the products-based activity?
No, it's always complementary with synergies. When it comes to industrial automation, I said +15%, but it was a +15% year-over-year, Q2 to Q2.
It was not a sequential improvement.
Eric Lemarié
Okay.
Guillaume Texier
No, that's fine. That's fine.
Maybe I was not clear. When it comes to datacom, I think the category overall was positive, I'm not sure.
When it comes to Tally, I know the answer. Tally in Q2 was slightly negative in terms of progression, compared to a super positive quarter last year, double-digit positive last year.
This was completely expected. We know that Tally is also a little bit dependent on the overall cycles of investment of the big telecom operators in the US.
We know that we have to be used to variations. Overall, we had a very good run, and we continue to have very positive prospects, but we have to get used to a road which is a little bit lumpy.
I think if you take the datacom category, it is probably quite positive because it includes a little bit of data center in Canada, where we have also experienced strong growth. I don't have the figure on top of my mind, but
Eric Lemarié
it's positive. Yeah.
Guillaume Texier
Yes, it's positive, absolutely.
Eric Lemarié
Thank you.
Operator
Mr. Texier, there's a last-minute registration from Aron Ceccarelli of Bank of America.
Guillaume Texier
Sure.
Aron Ceccarelli
Hello, hi. Yes, thanks for taking my follow-up.
Just again on the guidance on organic growth, because clearly strong momentum in the second quarter, you highlighted the strong backlog in the US, also in Canada, some good visibility. Is it just a level of conservatism, or are you baking in any kind of potential strong slowdown in Q4?
I understand you mentioned some deterioration in Europe and in the US, but I would like to have more light around that, how you think about it, please.
Guillaume Texier
Look, we are not flagging any particular slowdown. Now the second quarter was particularly good with a good timing of delivery of orders in data centers, with the additional effect of the air conditioning, which I'm not sure is going to repeat in H2.
There is, yes, a level of caution in the guidance. We have not gone absolutely all-in on the guidance because it's a guidance and we want to deliver it also.
Aron Ceccarelli
Understood. Thank you very much.
Operator
I'll turn it back to you, sir, for any closing remarks. Thank you.
Guillaume Texier
No particular closing remarks. As I said in conclusion to my presentation, we are proud of the set of results, both because there are good figures and also because they illustrate the success of what we have done over the last few years, and we hope to continue to deliver a very good year.
Thank you.
