Key Details

• Transaction date: 2026-09-24; Form 4 filed 2026-09-25 (appears timely).
• Prices: weighted average $17.02; execution range $17.00–$17.03.
• Shares sold: 500 and 800 (total 1,300). Total proceeds: $22,126.
• Shares owned after transaction: not specified in the Form 4 filing.
• Notable footnotes: transactions were made under a 10b5-1 plan adopted June 1, 2026 (F1); weighted-average price disclosed with range and offer to provide per-price details on request (F2); holdings are reported as held via Hodgkins Trust and Hodgkins LLC with disclaimers of Section 16 beneficial ownership (F3–F4).

Context
Because the sales were executed under a Rule 10b5-1 plan, they were likely pre-scheduled trades rather than discretionary sales made at the time. As a 10% owner (not an executive title), Hallen’s holdings are held through trust/entity vehicles and the filing includes standard disclaimers about beneficial ownership. The filing is factual and does not indicate motive.
