Array Digital (AD) CEO reports RSU vesting and 349-share tax withholding

Rhea-AI Filing Summary

ARRAY DIGITAL INFRASTRUCTURE, INC. President and CEO Anthony J. Carlson reported routine equity compensation activity tied to restricted stock units. On March 4, 2026, 1,004 restricted stock units were converted into 1,004 common shares at a price of $49.91 per share, increasing his direct common share holdings to 9,278 before tax withholding.

The restricted stock units were granted under the Array Long-Term Incentive Plan on March 4, 2024 and vest in three equal annual installments. Footnotes explain the award was increased by 167 units after a special dividend on February 2, 2026 to preserve fair value, and this filing reflects settlement of the second vesting tranche.

Carlson then disposed of 349 common shares at $49.91 per share through a code F transaction to cover taxes due on the vesting that occurs on March 4, 2026, leaving him with 8,929 directly owned common shares. The filing shows compensation-related conversions and tax withholding rather than open-market buying or selling.
