What is the source of the Spok Holdings (SPOK) RSUs reported by the COO?

The Restricted Stock Units were granted on January 3, 2023 under Spok’s 2023 Long Term Incentive Plan. They were designed to vest in Common Stock if specified company performance objectives were achieved for the year ending December 31, 2025, linking vesting directly to performance.

The Compensation Committee determined on March 4, 2026 that performance objective targets under the RSU award had been exceeded. As a result, additional shares of Common Stock vested and were awarded, increasing the total stock-based compensation reported in the Form 4 filing.

What does each Spok Holdings (SPOK) Restricted Stock Unit represent in this Form 4?
