[Form 4] Barrett Business Services Insider Trading Activity

Rhea-AI Filing Summary

Barrett Business Services Inc. (BBSI) – Form 4 insider filing

Director Mark Steven Finn reported two equity transactions dated 1 July 2025:

• 593 common shares acquired at a conversion price of $0.00 following the vesting of an equal number of restricted stock units (RSUs). Post-transaction direct ownership rises to 14,443 shares.
• 2,344 new RSUs granted (transaction code “A”) that vest in a single tranche on 1 July 2026. Finn now holds 2,344 RSUs outstanding.

No open-market purchases or sales occurred; the activity reflects normal equity incentive plan mechanics. The net change represents less than 0.1 % of BBSI’s ~7.0 million shares outstanding and therefore is not expected to be material for valuation.

Insights

Equity Compensation Analyst

TL;DR: Routine RSU vesting and grant; immaterial ownership change, neutral signal for BBSI shareholders.

The filing shows a standard one-for-one RSU conversion (593 units) into common stock, followed by a fresh annual grant of 2,344 RSUs to Director Mark Steven Finn. These awards are consistent with BBSI’s director compensation program and were executed at no cash cost, so they do not imply personal market conviction or provide pricing insight. The director’s aggregate direct stake remains modest at roughly 0.2 % of shares outstanding, and no shares were sold. From a governance perspective, the equity mix aligns director incentives with long-term shareholder value, but the small size renders the event non-impactful to trading dynamics or valuation.
