Thank you, Chris, and good morning, everyone. I'm proud to report an excellent quarter at Axalta. Overall, net sales were primarily flat while adjusted EBITDA was a record for any first quarter in Axalta's history. Margins are significantly improved, and we believe we have more room to grow. Our balance sheet has continued to improve with our net leverage ratio declining for 7 consecutive quarters. I'm very confident with our trajectory this year, which has led us to raise fiscal year guidance for adjusted EBITDA, adjusted diluted EPS and free cash flow. Yet, I believe we're just getting started transforming the company and unlocking the tremendous potential of our products, technology and organizational capability.
For the first quarter, net sales increased 1% year-over-year to $1.3 billion, with positive price mix. We remain committed to realizing the full value of our products and services, therefore, we continue to evaluate targeted pricing in select areas of the portfolio. Volume was approximately flat year-over-year with growth in Light Vehicle and Refinish offset by declines in Industrial and Commercial Vehicle given their softer macro environment. Adjusted EBITDA increased 22% year-over-year to $259 million, representing a record first quarter. This quarter ran ahead of guidance due to outstanding execution from the entire global team. Specifically, our commercial teams did a great job of winning new customers by focusing on accretive areas that will support a more profitable product mix and pricing for value.
Our operations teams focused on reducing backlog and beginning the Axalta performance system journey, which is gaining traction. Procurement overdelivered again, driving 11% better unit variable cost. Cost optimization has been the central focus since I joined the company and will remain a high priority moving forward. Adjusted EBITDA margins improved by 340 basis points to 20% reflecting significant progress towards a return to historic margins in the 20% to 21% range.
Profitability increased substantially across both segments. The largest margin contributions came from Light Vehicle and Industrial end markets, with profitability improvement in the latter stemming partly from our strategic shift towards higher-margin products.
Let's move to Slide 4 for details on our business segments. Refinish had another strong quarter with net sales 4% higher year-over-year. This represents the 13th straight quarter of better top line performance with a balanced contribution from price-mix, volume and FX. Market growth was roughly flat versus the prior year period across North America and EMEA. However, we are seeing above-market performance given our 600-net body shop win and the addition of 100 new points of distribution.
We're also getting traction with our strategic growth initiatives in adjacencies like U-POL aerosol, RAPTOR bedliners and accessories sold through our company-owned stores in Europe. Our acquisition of André Koch supports these strategic initiatives and has proved to be an excellent transaction for us. I'm very pleased with the pace of integration, which is ahead of our initial plan.
I believe that differentiated technology is the foundation of Axalta's competitive advantage and a key reason we continue to outpace market growth. I'm happy to announce that we were recognized with several prestigious R&D awards this quarter, all centered around efficient and sustainable innovation. There is no better example than Irus Mix, a fast, efficient, fully automated and completely hands-free mixing machines for the refinish industry. In addition to seeing strong customer demand in launching this product, it also won an Edison Award in the environmental and industrial solutions category.
Another bright spot in the quarter was Light Vehicle growth. Net sales improved by 4% year-over-year, mostly due to strong volumes, particularly in China. Volume growth in China improved by 20% as compared to 4% auto production growth, again, against the prior year quarter. We have partnered with the fastest-growing OEM, and this is a solid business for us at an attractive return. We win new business and build lasting partnerships in this market with our products, service and technology, which is exemplified with our recent recognition from General Motors as a Supplier of the Year.
Commercial Vehicle net sales declined by 4% year-over-year consistent with the expected slowdown in North America Class 8 production. We believe this market will further soften into the year before ramping back up in '25 and '26 ahead of the emission standards going into effect in 2027. Industrial net sales declined 6% year-over-year, driven by soft construction activity in North America and EMEA, which has offset improvement in new business wins. We have strategically deselected low-margin categories, which is yielding significantly improved profitability.
My main focus since joining Axalta has been to improve efficiency and performance across the company. I'm very proud of our achievements to date. We're starting to see the benefits of our actions we have taken in our financial results, but we believe there is more to come.
To further enhance our performance and results, we have announced a transformation initiative in February to enable us to be more proactive, responsive and agile. This program includes a global workforce reduction of approximately 5% and a shift in manufacturing capacity and capability. We expect this program to yield approximately $75 million in annualized run rate savings in 2026.
Before passing the call to Carl for a more detailed review of our first quarter financial performance, I want to thank Bob McLaughlin for his 10 years of service on the Axalta Board, including as Chair of the Audit Committee. Bob is elected to retire next month after the Annual General Meeting. He has been an incredible thought partner for the Board, and we wish him the very, very best.
