HIGH MICHAEL B 4

What Happened

• Michael B. High, a director of CoastalSouth Bancshares, Inc. (COSO), received an award of 868 restricted stock units (RSUs) on February 11, 2026. The Form 4 lists this as an award/acquisition (code A) of derivative securities; no purchase price or immediate cash value is reported (N/A).
• These RSUs are derivative awards that will convert into common shares on a one-for-one basis upon vesting. The award does not represent immediately issued common shares.

Key Details

• Transaction date: 2026-02-11; Filing date: 2026-02-13 (filed within the standard two-business-day Form 4 window).
• Shares/units granted: 868 RSUs. Price/value: N/A (award grant, not an open-market trade).
• Shares owned after transaction: Not disclosed in the provided filing details.
• Footnotes: F1 — RSUs convert one-for-one into common stock. F2 — 100% of the RSUs vest on 12/31/2026.
• Transaction type: Award/Grant of derivative securities (RSUs), not a purchase (P) or sale (S).

Context

• RSUs are a form of equity compensation that typically do not convey stock ownership, voting rights, or dividends until they vest and convert to shares. Because these RSUs vest on 12/31/2026, the economic interest and share issuance will occur at vesting (subject to any company withholding rules).
• Awards to directors are common as compensation and do not necessarily signal a personal purchase or sale decision; they differ from open-market buys or disposals.
