Key Details

• Transaction date: 2026-02-06
• Primary action: Exercise of options (transaction code M) — 10,300 shares acquired at $9.71 each (total $100,013)
• Corresponding derivative entry: 10,300 derivative units reported disposed at $0.00 (reflects conversion/cancellation of the option)
• Footnote: F1 — Fully vested
• Shares owned after the transaction: Not specified in the provided filing details
• Filing timeliness: Report filed on 2026-02-09 (within required SEC Form 4 timing; not flagged late)

Context

• Transaction code M indicates option exercise. The separate disposal line at $0.00 is a standard reporting method showing the option/derivative was converted/cancelled when shares were acquired.
• No sale of the new shares was reported here, so this was a cash exercise resulting in ownership of the acquired shares (not a cashless exercise).
• Purchases/exercises by executives are often watched by investors as a stronger signal than sales, but this report alone does not indicate the insider’s motivation.
