Key Details

• Transaction date: March 9, 2026.
• Total shares converted/issued: 53,013 (sum of 14,104; 16,562; 11,175; 11,172).
• Shares withheld for taxes: 19,113 at $5.49/share = $104,930 (net‑settlement/tax withholding; not an open‑market sale).
• Transaction codes: M = exercise/conversion of derivative (RSU conversion); F = payment of tax liability via share withholding.
• Footnotes: RSUs represent contingent rights to receive one share each (F1). The withheld shares were retained by the issuer on a net‑settlement basis to cover tax obligations tied to RSU vesting from grants on June 2, 2022; Mar 14, 2023; and Mar 15, 2025 (F2). Vesting schedules are described in the filing (quarterly installments per F3–F6).

Context

• These were RSU conversions (derivative-to-common stock), not purchases or open‑market sales. The company retained a portion of the shares to cover taxes (net settlement/cashless withholding), which is a routine administrative action and does not, by itself, signal a buy or sell decision by the insider.
