## Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
*Election of Directors*

On February 26, 2026, the Board of Directors (the "Board") of CoastalSouth Bancshares, Inc. (the "Company") voted to appoint Mr. J. Simon Fraser ("Mr. Fraser") to serve on the Board. His term commenced on February 26, 2026 and will expire at the Company's 2026 Annual Meeting of Stockholders, at which time he will be considered for election to a one-year term. Following the 2026 Annual Shareholder Meeting, Mr. Fraser is expected to serve on the Company's Audit Committee and Nominating and Governance Committee.

Mr. Fraser's appointment to the board was not pursuant to any arrangement or understanding with respect to any other person. There are no family relationships between Mr. Fraser and the Company, and, except for the loans to Mr. Fraser as described herein, there are no transactions between Mr. Fraser and the Company that would be required to be reported under Item 404(a) of Regulation S-K. The Company's subsidiary, Coastal States Bank, has several outstanding loan transactions with Mr. Fraser. These loans were made in the ordinary course of business, were made on substantially the same terms (including interest rates and collateral) as those prevailing at the time for comparable loan transactions with persons not related to Company, and did not involve and do not currently involve more than the normal risk of collectability or present other unfavorable features.

The Board has determined that Mr. Fraser is an independent director within the meaning of the Securities Exchange Act of 1934, as amended, rules and regulations promulgated by the SEC thereunder, and the listing standards of the New York Stock Exchange.
