3 Executive Summary • On July 1, 2020, Dan Peed took over as Chairman & CEO of UIHC seeking to de-risk the Company’s struggling personal lines business and allocate more resources towards our consistently profitable commercial lines segment. • The Company subsequently tightened underwriting guidelines, increased rates, began non-renewing risks, and reduced exposure by selling large portions of its personal lines business in 7 states to a third-party carrier. • In 2022, UIHC announced it was placing the remainder of its personal lines business underwritten by United Property & Casualty Insurance Company (UPC) into run-off, but in early 2023 UPC was ordered into receivership. • On March 1, 2023, UIHC disposed of UPC recognizing a significant gain within discontinued operations for the quarter ending March 31, 2023. This effectively accelerated our plan to exit personal lines. • UIHC still has a small exposure to the personal lines business underwritten by IIC in New York. However, we are seeking a buyer for IIC to complete our exit from the personal lines business as soon as practical. UIHC has undergone a major strategic transformation over the past several years. Our commercial lines business underwritten by ACIC has produced exceptional results over the long-term which we expect to continue and is our primary focus going forward.
