Context
This was largely a cashless-type sequence: options/awards vested or converted, shares were surrendered to satisfy tax withholding, and some shares were sold in the open market. The filing also notes Wojcik’s employment terminated on March 6, 2026 and remaining unvested awards were cancelled. These kinds of filings document taxable events and routine post-vesting sales; they are factual disclosures and do not by themselves indicate the insider’s future view of the company.
