AXA XL, the property and casualty division of global insurer AXA Group, has announced the promotion of Matthew Stitham to Chief Underwriting Officer (CUO), Casualty in the Americas.
Stitham succeeds Donnacha Smyth, who transitioned in November 2025 to the role of Global Chief Underwriting Officer, Casualty at AXA XL, overseeing casualty underwriting operations worldwide.
Based in San Francisco, Stitham will report to Donna Nadeau, Head of Large Commercial business.
He joined AXA XL in 2007 and has since demonstrated strong leadership and expertise in casualty underwriting, playing a key role in the company’s continued growth in the casualty market. Most recently, he served as Head of West Excess and Head of Excess Casualty.
Earlier in his career, Stitham held positions at Zurich and Travelers.
Nadeau commented, “Matt’s extensive experience, strategic vision, and deep understanding of the casualty market is a tremendous asset for our clients and our organisation as he assumes his new role. Under his guidance, we are confident that our casualty underwriting capabilities will continue to grow as we serve our clients as a trusted partner.
“In today’s uncertain environment—marked by rising claim severities, social inflation, and emerging liability risks—having seasoned professionals like Matt is crucial. His expertise helps our clients safeguard against catastrophic claims, stay compliant with evolving policy requirements, and proactively manage risks across various casualty lines—from auto to employment practices—supporting their financial stability and maintaining stakeholder trust in uncertain times.”
