United Security (UBFO) CFO David Kinross Sells Shares in Merger

What Happened

David A. Kinross, Chief Financial Officer of United Security Bancshares (UBFO), reported dispositions related to the company's merger. On 2026-04-01 he disposed of 95,733 shares at $10.51 each for proceeds of $1,006,154. Earlier, on 2026-03-24, 28,236 shares were surrendered with an $0.00 per-share value to cover tax liabilities (reported with code F).
These transactions are recorded as dispositions (codes D and F) and reflect merger-related actions rather than an open-market sale initiated for investment reasons.

Key Details

Transaction dates/prices:
- 2026-03-24: 28,236 shares surrendered for tax withholding (Code F), $0.00 per share (no proceeds).
- 2026-04-01: 95,733 shares disposed to the issuer (Code D) at $10.51 per share = $1,006,154.
Filing: Form 4 filed 2026-04-03 (appears timely given the 4/01 disposition).
Shares owned after the reported transactions: not specified in the filing.
Footnote: Dispositions were pursuant to the Agreement and Plan of Merger dated December 16, 2025. The merger became effective at 12:01 a.m. on April 1, 2026; each United Security share (other than excluded/dissenting shares) was converted into the right to receive 0.4520 of a Community West Bancshares share. Outstanding unvested restricted stock awards vested and then received the merger consideration.

Context

Code F typically means shares were surrendered to satisfy tax withholding (not an open-market sale). Code D denotes disposition to the issuer (common in mergers/closing transactions).
Because these actions were tied to the merger, they should be viewed as corporate-transaction driven rather than a personal investment signal by the CFO.
