Departure of Directors

On November 18, 2025, Mr. Boris Gutin notified the Board of Directors (the "Board") of CoastalSouth Bancshares, Inc. (the “Company”) that he is resigning from the Board of Directors, effective November 19, 2025.

Mr. Gutin was originally designated to the Board by GCP Capital Partners and its related funds, an investor in the Company's recapitalization in 2017. In connection with the Company’s recent initial public offering, and consistent with GCP's customary practice of not having representatives serve on the boards of public companies, Mr. Gutin determined that it was an appropriate time to step down.

Mr. Gutin expressed strong support for the Company, its management team, and the Board of Directors, and conveyed his appreciation for the opportunity to serve. His resignation is not the result of any disagreement with the Company on any matter relating to its operations, policies or practices.

The Board of Directors sincerely thanks Mr. Gutin for his dedicated service and valuable contributions during his tenure.
