Thank you, Guillaume. We are now on Slide 14. As Guillaume said, H1 2025 was in line with our expectations, both in terms of growth, profitability and cash generation. You can see here the key financials for the period.
Total revenues reached EUR 1.2 billion, up by 10% compared to last year, driven by the B2C volume growth. GPU once again stood at European leading level of EUR 2,317 per B2C car sold. Adjusted EBITDA reached nearly EUR 33 million, twice as much as last year. The group once again managed to decrease its operating working capital by another 3 days versus last year. As a result, the group generated almost EUR 24 million positive cash flow in H1 2025, excluding the payment of online cars earn-out and the share buyback plan.
Now on Slide 15 for more details on revenues by segment. Overall, our B2C sales are up by around 10% in value and in volumes, well balanced between our two segments. B2C refurbished volumes grew by 11% with an acceleration between Q1 and Q2, 8% in Q1 and 14% growth in Q2. This acceleration is partly due to favorable calendar and base effects in Q2 expected to be partly offset in Q3, for which we, therefore, expect slower growth.
B2C preregistered volumes, mainly sold in France and in Belgium, keep improving by 7% versus last year. This growth is driven by the end of the catch-up effect in Belgium, while volumes have now stabilized in France. B2B revenues decreased by 3%. The B2B segment activity, as you know, is driven by the volume of vehicles purchased to private customers, which has now stabilized.
Finally, revenues from services increased by 7%, driven by the B2C growth. The penetration of the financial services, which account for a significant portion of our services margins remained rather stable over the semester at 44%.
I'm now on Slide 16. The slide shows the usual revenue split by country. In France, revenues increased by 9%, driven by a strong growth in refurbished cars by 17%, whereas preregistered cars have now stabilized as expected. In Belgium, revenues increased by 19%, driven by the end of the catch-up effect in the preregistered vehicle segment, where volumes are up by 41%.
In Spain, revenues grew by 8% compared to the first half of 2024 despite the flooding of the Valencia site in October 2024. The Valencia site, which includes a point of sale and a refurbishing center, needed a complete overhaul and reopened only 2 weeks ago.
Strong growth continues on the U.K. market with another 19% growth rate in the semester with a particularly favorable base effect during Q2. And in Austria, revenues are down by 5%, reflecting here an unfavorable base effect after an exceptional 2024 year of hyper growth, which benefited from one-off sourcing opportunities.
In Italy, B2C revenues increased by 2%. If we take into account the volumes sold to other group entities, total volumes increased by 38%, enabling us to improve our unit economics versus last year.
Moving on to Slide 17 now and our profitability. We keep maintaining our discipline, further improving both GPU and costs. We have improved our unit margin by approximately EUR 150 per unit versus last year. The services margin has now stabilized. And on the car margin itself, what we call the metal margin, we have confirmed the improvements made in H2 2024, meaning improved car selection and car pricing, thanks to team training and our technologies, more efficient reconditioning and logistics operations.
As a reminder, our GPU is calculated in the same manner as our peers in the U.S., including all cost of refurbishing, rent and labor, which is not the case for some of our European peers. Using comparable methodology, we are keeping our leadership position among listed peers in Europe.
We also continue keeping under control our SG&A, as you can see on the chart on the right side. Those amounted to approximately EUR 108 million in H1 2025, which is a moderate increase of less than 5% compared to H1 2024. We kept investing into our brands while improving the efficiency of our marketing spend.
And of course, we continue to invest in new branches and in our sales teams to fuel our 10% volume growth. As a result, per B2C cars sold, the SG&A decreased again by close to EUR 100 per unit versus last year. Going forward, we intend to maintain the same level of discipline and bring further up these productivity gains.
If we now move to Slide 18, we see the EBITDA bridge that illustrate the profitable growth achieved in H1 2025. H1 EBITDA has doubled versus last year from EUR 16 million to EUR 33 million, and this was driven by solid volume growth, 10% year-on-year, margin improvement, thanks to strong operational execution and moderate SG&A increase to support our growth while delivering improved productivity.
Moving to Slide 19. Finally, let's take a look at our cash flow generation. We keep reducing our operating working capital, thanks to continued discipline on our inventories, hence, a reduction from 27 days last year to 24 days of revenues in 2025. We believe we still have room for improvement on this topic where the group is already best-in-class.
Our capital and expenditure stood at EUR 5.4 million in this first semester, down from EUR 6.8 million last year as we are increasingly mutualizing our investments at group level. Thanks to increased profitability, reduced operating working capital and increasingly mutualized CapEx, we generated EUR 24 million positive cash flows in H1, which enabled to cover for the online cars earn-out payment for EUR 7 million and our share buyback program for EUR 3 million.
Our financial net debt, excluding IFRS 16, went further down from EUR 61 million to EUR 47 million. As a reminder, this net debt does not include the GBP 30 million estimated payment to be made for the remaining 40% of shares of CarSupermarket and estimated to be paid out in FY 2026. We still have more than EUR 200 million of undrawn credit lines with no covenants attached with Stellantis and with local financial partners.
During the semester, the group has renegotiated the terms of some of its credit lines with Stellantis, converting short-term credit lines or those with fixed maturities in 2026 or 2027 into a credit facility that can be drawn at any time for a maximum duration of 3 years and amounting to EUR 100 million. This shows once again the trust relationship that exists between Aramis and its partner, Stellantis.
With that, I hand the floor back to Guillaume for the outlook and guidance.
