Arch consolidates leadership under single president

Arch Capital Group  announced a leadership transition that places all three of its operating segments—insurance, reinsurance, and mortgage insurance—under President Maamoun Rajeh.

Rajeh, who previously oversaw Arch’s Reinsurance and Mortgage businesses, will now also assume responsibility for the Insurance segment while continuing to report to CEO Nicolas Papadopoulo. The move establishes a single-president model across the organization.

Rajeh joined Arch in 2001 and has led the company’s reinsurance business through its growth into a global provider. He also took responsibility for the mortgage insurance segment in 2024.

As part of the transition, David Gansberg is stepping down as President and leaving the company. Arch credited Gansberg with helping build the organization during his tenure.

According to Papadopoulo, the leadership change is intended to enhance alignment, accountability, and coordination across Arch’s underwriting operations worldwide.

Arch Capital Group, headquartered in Bermuda, reported approximately $26.9 billion in capital as of March 31, 2026. The company provides insurance, reinsurance, and mortgage insurance through its subsidiaries globally.
