**PRESS RELEASE**

**Arch Capital Group Ltd. Announces Leadership Transition** 

**PEMBROKE, BERMUDA — June 3, 2026 —** Arch Capital Group Ltd. (NASDAQ: ACGL) ("Arch" or the "Company"), a leading provider of insurance, reinsurance and mortgage insurance globally, today announced the expansion of Maamoun Rajeh's role as President. Rajeh, who most recently oversaw Arch's Reinsurance and Mortgage segments, will also take on responsibility for Arch's Insurance segment as the Company moves forward under a single President model. Rajeh will continue to report to Chief Executive Officer Nicolas Papadopoulo.

David Gansberg is stepping down from his role as a President of Arch and departing the company following a distinguished tenure, having played an important role in building the organization to its current position.

"Maamoun has been integral to Arch's success since 2001 and brings a deep understanding of the Property and Casualty business," said Papadopoulo. "Under Maamoun, Arch Re has become a leading global reinsurance provider and, since assuming responsibility for the Mortgage group in 2024, he has demonstrated the curiosity and accountability that make him the right leader to guide our three business segments. His expanded role reflects our focus on clarity, accountability and alignment across our global underwriting operations. I look forward to continuing to work with him in the coming years."

Papadopoulo added, "I also want to recognize the significant contributions David made to Arch's success during his tenure. I wish him continued success in the future."

Rajeh said, "I'm grateful for this opportunity to take on this expanded role and to continue to work closely with Nicolas, the rest of Arch's leadership team and our Board of Directors. With our global platform, world-class talent and data-driven underwriting culture, Arch remains well-positioned for continued success. I'm energized and focused on enhancing our Insurance segment's leadership position in the markets where we operate."
