AM Best said that the Credit Ratings (ratings) of Southern Vanguard Insurance Company (Southern Vanguard) (Austin, Texas) and the members of Stonetrust Insurance Group (Stonetrust) (Baton Rouge, Louisiana) remain unchanged following the May 27, 2025, announcement that Wintaai America Inc. (Wintaai), Stonetrust’s holding company, will be acquiring Southern Vanguard, subject to regulatory approval.
The members of Stonetrust have a Financial Strength Rating (FSR) of A- (Excellent) and Long-Term Issuer Credit Ratings (Long-Term ICR) of “a-” (Excellent) with positive outlooks. Southern Vanguard has an FSR of A- (Excellent) and a Long-Term ICR of “a-” (Excellent) with stable outlooks.
Wintaai owns 99.94% of Stonetrust and the remaining is owned by various employees. Wintaai will own 100% of Southern Vanguard following conclusion of the transaction, which is pending regulatory approval and expected to close by July 2025. Aside from the transaction cost, Wintaai will also add capital to Southern Vanguard as a post-close contribution.

The credit ratings agency will continue to evaluate each of these organizations independently while monitoring the progress and the effects of this transaction over time.
