Insights

Equity compensation analyst

CFO receives RSU and PSU grants tied to time-based and performance vesting, with no open-market trades.

The CFO, Carlos Doglioli, was granted 18,032 time-based RSUs and 18,032 performance-based RSUs (PSUs). These are compensation awards with a grant price of $0.0000 per unit, not market purchases or sales, and therefore carry limited trading signal.

The time-based RSUs vest in four equal annual installments on March 17, 2027, 2028, 2029 and 2030. The PSUs vest based on relative total shareholder return versus the Russell 2000 Index over a period from March 17, 2026 to March 17, 2029, with payout ranging from zero to 150% of target, reinforcing long-term performance incentives.

After the grant, Doglioli directly owns 50,449 shares of common stock as reported. Because these awards are standard equity compensation without cash proceeds or discretionary trading, they are best viewed as routine alignment tools rather than a directional view on ATN International’s near-term share price.
