Ascot has announced a leadership transition as the company moves to expand its treaty reinsurance offerings in the United States.
Justin Keith (pictured above), who serves as CEO of Ascot Bermuda Limited, will relocate to the US later this year to lead the initiative.
The expansion will build on Ascot's facultative reinsurance operations in the US market. Keith's background includes developing and managing multidisciplinary treaty portfolios.

The leadership changes follow the recent appointment of Ashleigh Edwards as group head of ceded reinsurance effective January 5. Edwards, who joins from RenaissanceRe where she served as SVP and global head of casualty reinsurance, will work with ceded reinsurance leaders in the UK, Bermuda, and the US to align resources and strategy.
The US treaty expansion adds to Ascot's recent reinsurance activity. In August 2025, the company partnered with Antares Capital to launch Wayfare Re, a Bermuda-based casualty sidecar capitalized with approximately $500 million. The vehicle provides dedicated underwriting capacity for casualty business in the US and Bermuda markets.
Also in August, Ascot launched Prime Propel, a combined contractors professional and environmental liability product for the construction sector, as part of a broader environmental growth plan.

These moves reflect Ascot's continued build-out of specialty underwriting in the US, which increases the need for coordinated risk transfer across lines. The company's ceded reinsurance strategy now includes coordination with Leadline Capital Partners, its third-party capital management platform.
Amen said the changes are intended to support the company's growth objectives.
"We expect these updates to enable continued success and growth at Ascot," Amen said. "We also look forward to working more extensively with our reinsurance clients across North America and continuing to deliver the value they have come to expect from our organization."
