Key Details
- Transaction date: 2026-05-21 (filed 2026-05-22 — filing appears timely).
- Exercise: 10,000 shares at $14.98 per share — total cost $149,800 (transaction code M).
- Sale: 10,000 shares sold in the open market at a weighted-average price of $18.34 — proceeds $183,435 (transaction code S). Footnote F1: sale prices ranged from $18.25 to $18.50; $18.34 is the weighted-average.
- Additional line: 10,000-share exercise/conversion reported at $0 (value $0); footnote F2 says this reflects transactions not required to be reported under Section 16.
- Shares owned after the transactions: not specified in the provided filing excerpt.
Context
- The filing shows an option exercise and same-day sale of shares — commonly executed as a cashless exercise or immediate market sale, which converts option value to cash rather than increasing long-term shareholdings. Sales by executives are often routine (to cover taxes, exercise costs, or diversify) — the filing provides facts but not the insider’s motivation.
- Transaction codes: M = exercise/conversion of derivative (options/RSU conversion), S = sale. The $0 conversion entry is noted as not subject to Section 16 reporting per the filing.
