Insights

Equity compensation analyst

CEO receives time-vested RSU grant, a routine equity award.

The filing shows Quentin S. Blackford, President and CEO of iRhythm Holdings, Inc., receiving a grant of 31,842 RSUs, each representing one future share of common stock. No cash changed hands; this is equity-based compensation.

The RSUs vest 25% on March 1, 2027 and then annually, contingent on continued service. This structure encourages long-term retention and alignment with shareholders but also adds to potential future share count as units vest and settle into common stock.

After this grant, Blackford directly holds 217,968 shares. The actual impact on ownership and dilution will depend on how many RSUs ultimately vest under these service-based conditions.
