Filing records trust-held shares converted into merger consideration, not open-market selling.

This Form 4 shows indirect holdings associated with director Jagroop Gill being disposed of to United Security Bancshares as part of its merger into Community West Bancshares. The D code reflects an issuer disposition linked to the merger closing, not a sale in the market.

Agreement and Plan of Merger regulatory

"Disposed of pursuant to the Agreement and Plan of Merger, dated as of December 16, 2025"

An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.

Merger Consideration financial

"was converted into the right to receive 0.4520 of a share of common stock of Community West (the "Merger Consideration")"

Merger consideration is the total payment a company or buyer offers to shareholders of a target company in exchange for combining the two businesses, and can include cash, shares in the surviving company, debt assumption, or a mix of these. Investors care because the form and amount affect the deal’s value, tax consequences, immediate cash received versus future ownership, and the risk and upside of holding new shares — similar to choosing between cash now or stock that could grow later.

Effective Time regulatory

"The Merger became effective at 12:01 a.m. on April 1, 2026 (the "Effective Time")"

restricted stock award financial

"each outstanding unvested Company restricted stock award automatically vested in full"

A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.

dissenting shares regulatory

"each share of Company common stock, other than excluded shares and dissenting shares, was converted"

Dissenting shares are shares held by investors who formally oppose a proposed corporate action—such as a merger or takeover—and choose to demand a cash payment for the value of their stock instead of accepting the deal’s terms. This matters to investors because it can slow or complicate a transaction, trigger a legal process to set a fair price, and affect how much cash a company must pay out, which in turn influences the financial outcome for all shareholders.
