PRIOR MICHAEL T 4

What Happened Michael T. Prior, Executive Chairman and a director of ATN International (ATNI), had 2,378 shares withheld by the company on 2026-03-25 to satisfy his tax obligation arising from the vesting of previously granted Restricted Stock Units (RSUs). The shares were valued at $27.92 each, totaling approximately $66,394. This was a tax-withholding disposition (code F), a routine administrative action rather than an open-market sale.
