• Transaction date: 2026-03-11
• Exercise: 8,667 shares acquired at $2.22 each — total ~$19,241
• Reported disposition: 8,667 shares at $0.00 (listed as "Derivative")
• Shares owned after transaction: not specified in this filing

Context

• This filing reflects an option exercise (insider acquiring shares). The paired disposition at $0.00 is often used in filings to reflect shares surrendered or withheld in connection with an exercise (e.g., to cover tax withholding or exercise costs), but the Form 4 does not detail the reason. No sale of shares on the open market was reported in this filing.
