## On May 1, 2026, CoastalSouth Bancshares, Inc. (the "*Company*") issued a press release. A copy of the press released is furnished as Exhibit 99.1 to this Current Report on Form 8-K (this "*Report* ").

## Item 8.01 Other Events.
The Company announced today that its Board of Directors has authorized a stock repurchase plan (the "***2026 Repurchase Plan***"), pursuant to which the Company may purchase, from time to time, up to an aggregate amount of $15.0 million of its shares of common stock. The 2026 Repurchase Plan will become effective on May 1, 2026, and will expire on April 30, 2027, unless extended by the Board.
