We're closely monitoring developments across energy, logistics, and the broader supply and demand landscape as it relates to the evolving situation in the Middle East. In Mobility, more than 50% of our revenue is now tied to raw material indices, which provides a natural hedge against cost volatility.
Even amid top-line pressure, our Adjusted EBITDA margins have exceeded 20% for nine consecutive quarters, underscoring the durability of our operating model. In Refinish, net body shop wins increased 10% year-over-year and generated net sales growth in the first quarter in three out of our four regions. In Mobility, we delivered record net sales in the first quarter of $452 million and growth in three out of our four regions. Commercial Transportation Solutions, which was a bright spot in 2025, also delivered record first quarter sales, driven by continued success with new business wins.
Gross margin was 33%, down slightly from last year, driven primarily by unfavorable mix from lower volumes in North America. Adjusted EBITDA in the quarter was $259 million, resulting in an adjusted EBITDA margin of 20.6%. Adjusted diluted earnings per share was $0.56, exceeding our outlook by 12%, supported by lower interest expense and stronger overall earnings in the quarter. Cash provided by operating activities was $68 million, a company first quarter record.
