Arch Capital Group Ltd. has expanded the role of Maamoun Rajeh as president, consolidating oversight of the company’s three business segments under a single leader, the Bermuda-based insurer announced.
Rajeh, who previously oversaw Arch’s reinsurance and mortgage segments, will assume additional responsibility for the insurance segment as the company transitions to a single-president model, according to the announcement. He will continue to report to chief executive officer Nicolas Papadopoulo.
The expanded role comes as Arch continues to invest in growing its insurance platform. In April, Arch Insurance EU launched a new European property business and opened an office in Milan, expanding its presence in Continental Europe. The company said the move would broaden its underwriting capabilities across property, accident and health, cargo and logistics, and general liability lines, supporting its strategy of building a stronger multi-line property and casualty insurance operation in the region.
Rajeh will also take on oversight of an insurance segment that has been integrating the US MidCorp and entertainment insurance businesses acquired from Allianz in 2024. The transaction expands Arch’s commercial insurance footprint in the United States and adds specialty underwriting capabilities.
The change comes as David Gansberg departs the company, stepping down from his position as president of Arch Capital.
Papadopoulo cited Rajeh’s track record across multiple segments as the basis for the expanded appointment.
“Maamoun has been integral to Arch’s success since 2001 and brings a deep understanding of the Property and Casualty business,” Papadopoulo said. “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.”
Papadopoulo said the restructuring reflects a strategic priority for the company.
“His expanded role reflects our focus on clarity, accountability and alignment across our global underwriting operations,” he said. “I look forward to continuing to work with him in the coming years.”
Papadopoulo also acknowledged Gansberg’s contributions.
“I also want to recognize the significant contributions David made to Arch’s success during his tenure,” he said. “I wish him continued success in the future.”
Rajeh expressed confidence in the company’s direction.
“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,” he said. “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.”
The leadership transition also comes as Arch continues to emphasize specialty insurance and underwriting discipline. Speaking at an investor conference in March, company executives said Arch remained focused on deploying capital to businesses offering the strongest risk-adjusted returns.
