Robert S. Briggs, a director of First US Bancshares, Inc. (FUSB), received 94.22 phantom stock units on 09/30/2025 under the company's Non-Employee Directors Deferred Compensation Plan.

Insights

Corporate Governance Expert

TL;DR: Director received deferred-compensation phantom stock that converts 1-for-1 to common shares, modestly increasing direct holdings.

The filing documents a routine grant of phantom stock units under the Non-Employee Directors Deferred Compensation Plan, credited for accrued quarterly dividends. Such grants are standard for aligning director interests with shareholders without immediate share issuance. The conversion and settlement terms—1-for-1 conversion and settlement in common stock at the end of deferral—are explicitly stated, as is the post-transaction direct beneficial ownership of 16,361.15 shares. There is no indication of cash settlement, acceleration, or other unusual terms in the disclosed text.

Compensation/Risk Analyst

TL;DR: This is a routine deferred-compensation accrual; impact is neutral absent additional compensation or dilution details.

The transaction records 94.22 phantom units valued notionally at $12.02 each, implying a small incremental long-term interest for the director. Because these units are to be settled in stock at deferral termination, they will result in share issuance only on settlement, not immediately. The filing does not disclose vesting conditions, settlement date, or aggregate plan dilution, so materiality cannot be assessed from the form alone.
