Southern Vanguard Insurance Company, based in Austin, Texas, is set to be acquired by Wintaai America Inc., the holding company for Stonetrust Insurance Group. This announcement came on May 27, 2025, and the deal is pending regulatory approval. Wintaai currently owns nearly all of Stonetrust, and once the acquisition is finalized, it will own 100% of Southern Vanguard.
Both Southern Vanguard and Stonetrust have strong ratings from AM Best, with Southern Vanguard holding an A- (Excellent) Financial Strength Rating and a Long-Term Issuer Credit Rating of “a-” (Excellent). Stonetrust also has the same ratings, but with a positive outlook. These ratings are not expected to change significantly due to the acquisition.
Wintaai plans to not only purchase Southern Vanguard but also to contribute additional capital to strengthen the company after the deal closes, which is anticipated by July 2025. Despite the acquisition, both companies will continue to operate independently. Mike Dileo will remain the president and CEO of Stonetrust, while Cory Moulton will continue as president and CEO of Southern Vanguard. Stonetrust will keep its headquarters in Baton Rouge, Louisiana, and Southern Vanguard will stay in Austin, Texas.
The members of Stonetrust include Stonetrust Commercial Insurance Company and Stonetrust Premier Casualty Insurance Company. AM Best has stated that it will keep monitoring both companies and evaluate their performance independently during this transition.
