A Letter from our Chairman and Chief Executive Officer

To Our Investors,

On behalf of the Board of Directors of Cooper-Standard Holdings Inc. (the “Board”), I am pleased to invite you to attend the

2026 Annual Meeting of the Stockholders (the “Annual Meeting”) to be held virtually May 14, 2026, beginning at 9:00 a.m.,

Eastern Time.

By nearly every measure, 2025 was the strongest operational year in Cooper Standard’s history - an especially meaningful

achievement as we celebrated our 65th anniversary. This operational excellence drove results for the year that exceeded our

original business plan and expectations despite significant industry disruption, a reflection of our disciplined execution of our

strategic priorities, continued improvements across our entire business, and strong alignment across our teams. Our focused

investments in innovation, operational excellence, and customer partnership are strengthening the Company and positioning

us well for the future. Our achievements in 2025 included:

•Strengthening financial results

◦Margin expansion, positive cash flow and 24% increase in operating income compared to 2024;

◦$298 million in net new business awards, 74% related to innovation products;

•Operational excellence

◦World-class safety benchmarks with a total incident rate of 0.24 per 200,000 hours worked, our best year ever,

including 31 plants that completed the year with zero reported incidents;

◦World-class product quality, launches and customer service, including 99% green customer scorecards for product

quality, and 98% green customer scorecards for program launches;

•External recognition and awards

◦SPE Automotive Innovation Award Finalist for our Quick Connector with Integrated Temperature Sensor;

◦2025 Automotive News PACE Pilot recognition for our eCoFlow™ Switch Pump technology;

◦One of Newsweek’s America’s Most Responsible Companies for the seventh consecutive year;

◦Leader in Sustainability recognition from Nissan;

◦2025 EcoVadis Silver Status 1, the eighth consecutive time for evolving sustainability achievements;

◦2024 Ford Supplier of the Year Award;

◦Toyota Motor North America for Supplier Excellence;

◦2024 GM Supplier of the Year, the eighth consecutive time earning this recognition;

◦USA TODAY America’s Best Climate Leaders 2025 List.

These accomplishments were driven by our world-class culture and unwavering commitment to integrity and doing business

the right way. Building on the momentum of 2025, we remain confident in our strategy and are optimistic about 2026 as we

continue to position Cooper Standard for sustainable, long-term profitable growth and value creation.
