Leon Justin M 4

What Happened

• Justin M. Leon, SVP Corporate Development at ATN International (ATNI), received shares when performance-based awards vested on March 7, 2026. The report shows 3,190 shares acquired upon vesting of performance stock units (PSUs). Portions of the award were withheld to cover tax obligations: 1,424 shares ($34,432) and 613 shares ($14,822), totaling 2,037 shares withheld and $49,254 in tax withholding. The filing also reports conversion/settlement of 5,500 derivative shares (reported as disposed with $0 proceeds), reflecting the award/settlement mechanics rather than an open-market sale.

Key Details

• Filing date: March 10, 2026; transaction date(s): March 7, 2026.
• Acquired: 3,190 shares from vested performance-based PSUs.
• Withheld for taxes: 1,424 shares ($34,432) and 613 shares ($14,822) — total 2,037 shares ($49,254).
• Reported derivative conversion/settlement: 5,500 shares reported as disposed at $0.00 (reflects award/settlement mechanics).
• Footnotes: PSUs vested at 58% of target based on relative total shareholder return (TSR) vs. the Russell 2000 for the performance period ending Mar 7, 2026 (per filing). Other footnotes confirm the withheld shares were to satisfy tax obligations from vested PSUs and previously granted restricted stock units.
• Shares owned after the transaction: Not specified on the Form 4.

Context

• These transactions are award vesting and related tax-withholdings, not open-market purchases or sales; tax-withholding (code F) is routine when restricted/performance awards vest. The PSU payout was performance-based (relative TSR), so the number of shares issued (58% of target) reflects partial achievement of those goals. The reported derivative conversion/exercise entries appear to be part of the award settlement mechanics (no cash proceeds).
