What Happened
Brad W. Martin, CEO of ATN International (ATNI), had a total of 6,795 shares withheld by the company to satisfy tax obligations from the vesting of previously granted Restricted Stock Units (RSUs). The withholding occurred in two parts: 2,299 shares at $24.65 each (worth $56,670) on 2026-03-12, and 4,496 shares at $24.49 each (worth $110,107) on 2026-03-13 — total value approximately $166,777. This was a tax-withholding disposition (code F), not an open-market sale.
