Former CNA and Catalina executive to lead strategy for run-off portfolios following AIG renewal-rights sale

Everest Group has appointed Gary Haase as executive vice president and CEO of legacy operations, effective 1 December 2025.
Haase (pictured) will report to Jim Williamson, Everest’s president and CEO, and will join the company’s executive leadership team.
The move follows Everest’s $2bn renewal-rights sale of its commercial retail insurance business to AIG as the group refocuses on core, higher-performing global operations.
Haase will oversee strategy and execution across Everest’s legacy insurance portfolios, with a focus on capital efficiency and long-term value.
Williamson said Haase’s breadth of experience made him a strong addition to the senior team.
“Gary’s broad and diverse experience, from actuarial and claims to M&A and technology transformation, makes him uniquely qualified for this role,” he said.
“His proven ability to modernise complex legacy portfolios and integrate analytics to unlock value will strengthen our legacy operations, enhance capital deployment and support Everest’s strategy for sustained, profitable growth.”
Haase brings more than two decades of experience across insurance, reinsurance and financial services. He has recently served as an executive adviser to private equity and technology firms on insurance M&A and AI transformation.
Before that, he was chief operating officer and an executive vice president at CNA Financial, leading enterprise technology, data and analytics, and operations, including the development of CNA’s cloud-native analytics and automation platform.
Haase previously spent more than a decade with Catalina Holdings, rising to group COO and overseeing global run-off operations across multiple jurisdictions. He began his career in actuarial and reinsurance roles at Quanta U.S. Holdings and Aon Benfield.
“Everest’s global reach and disciplined underwriting platform create a powerful foundation for opportunity,” Haase said.
“I look forward to partnering with Jim and the leadership team to optimise Everest’s legacy business and advance its long-term strategy,” he added.
