Hammack Heather 4

What Happened

• Heather Hammack, a director of United Security Bancshares (UBFO), disposed of 16,398 common shares at $10.51 per share for a total of $172,343, and had an additional 15,000 derivative shares reported as disposed on April 1, 2026. These transactions were made pursuant to the Agreement and Plan of Merger with Community West Bancshares, which became effective at 12:01 a.m. on April 1, 2026.

Key Details

• Transaction dates: April 1, 2026 (reported on Form 4 filed April 3, 2026). Filing appears timely (filed within the normal 2-business-day window).
• Cash sale: 16,398 shares @ $10.51 = $172,343.
• Derivative disposition: 15,000 shares reported as "derivative" with no per-share price shown (N/A) on the form.
• Shares owned after transaction: not specified in the filing.
• Footnotes: (F1) The dispositions were pursuant to the Merger Agreement; each Company share converted into the right to receive 0.4520 of a share of Community West, and outstanding unvested restricted stock awards vested and became entitled to the merger consideration. (F2) Reporting person's stock options were converted into the right to receive any amount determined under the merger formula (per the filing language relating to a $10.29 VWAP reference).
• No indication of a 10b5-1 plan, tax-withholding surrender reason explicitly given, or late filing flag in the document.

Context

• These were merger-related dispositions, not routine open-market trades: some shares were converted into Community West stock per the merger, and some were paid out at a per-share amount shown on the Form 4. Derivative entries reflect conversion/settlement of awards or options under the merger terms — the Form 4 lists value for the cash-settled portion (the 16,398 shares) and shows N/A where the consideration was stock or otherwise not reported as a per-share cash price.
• Facts only — this filing documents how Hammack’s holdings were treated in the merger; it does not reveal her personal motives.
