Arch Capital Group has expanded the responsibilities of Maamoun Rajeh as part of a leadership restructuring that consolidates oversight of its three operating segments under a single president.

The Bermudian-based re/insurer announced that Mr Rajeh, a veteran executive who serves as president of the company and who previously oversaw Arch’s reinsurance and mortgage businesses exclusively, will now also take charge of the insurance segment. He will continue to report to Nicolas Papadopoulo, the chief executive.

The move follows the departure of David Gansberg, who is stepping down from his role as president and leaving the company.

Mr Papadopoulo said the change was designed to strengthen alignment across the group’s global underwriting operations.

“Maamoun’s expanded role reflects our commitment to clarity, accountability and alignment across our businesses,” he said in a statement.

Mr Rajeh joined Arch in 2001 and has held a series of senior leadership positions during his tenure. He assumed responsibility for the company’s mortgage segment in 2024.

The new structure streamlines Arch’s insurance, reinsurance and mortgage operations under a single president.

Arch Capital provides its products through wholly-owned subsidiaries operating worldwide and reported approximately $26.9 billion in capital as of March 31.

Mr Papadopoulo also thanked Mr Gansberg for his contributions to the company during his time with Arch.
