PRIOR MICHAEL T 4

What Happened

• Michael T. Prior, Executive Chairman and Director of ATN International (ATNI), received equity awards on March 17, 2026: 13,524 restricted stock units (RSUs) and 13,524 performance-based RSUs (PSUs). The Form 4 reports $0 acquisition price for these grants (typical for awards).
• The RSUs vest in four equal annual installments on March 17 of 2027, 2028, 2029 and 2030. The PSUs are performance-contingent and may payout between 0% and 150% of target depending on relative total shareholder return (TSR) versus the Russell 2000 for the performance period.

Key Details

• Transaction date: 2026-03-17; Form 4 filed: 2026-03-27 (filed 10 days after the grant; later than the usual 2-business-day Form 4 deadline).
• Grants: 13,524 RSUs (time-based) + 13,524 PSUs (performance-based). Reported price/value: $0.
• PSU performance period: March 17, 2026 – March 17, 2029; payout range 0%–150% of target (0 to 20,286 shares possible from the PSUs).
• Vesting schedule for RSUs: four equal installments (2027–2030).
• Shares owned after the transaction were not included in the provided extract.
• Footnotes: F1 describes RSU vesting schedule; F2–F3 explain PSU TSR benchmarking to the Russell 2000 and payout range.
• Filing timeliness: The Form 4 was filed 10 days after the grant date — outside the typical 2-business-day window — which investors may note when assessing reporting practices.

Context

• These are equity awards (not open-market purchases or sales); they do not represent an immediate cash transaction or sale of shares. PSUs are conditional — payout depends on ATN’s relative TSR versus the Russell 2000 over the stated performance period.
• For retail investors, grants are disclosures of potential future insider ownership rather than direct bullish/bearish trading signals. Late filing can affect the timeliness of public disclosure but does not, by itself, indicate the substance of the award.
