OBOYLE KEVIN C 4

What Happened

• Kevin C. O'Boyle, a director of iRhythm Holdings, Inc. (IRTC), received a grant of 1,573 restricted stock units (RSUs) reported as an acquisition on May 27, 2026. The filing shows an acquisition price of $0.00 for the award (typical for compensation grants); no cash was paid.

Key Details

• Transaction date: 2026-05-27; Form 4 filed: 2026-05-29 (timely within SEC reporting window).
• Transaction type: A = Award/Grant of RSUs (1,573 shares).
• Reported price: $0.00 (RSU grant, not an open-market purchase).
• Shares owned after transaction: not specified in the Form 4.
• Footnote: Each RSU represents a contingent right to one share of IRTC common stock; vesting occurs on the earlier of (i) one year after grant or (ii) the date of the company's next annual meeting.
• Remarks: The filing notes a Jan 12, 2026 holding-company reorganization converting prior securities 1:1 to the current issuer; Exhibit 24 (Power of Attorney) is attached.

Context

• RSUs are compensation awards that convert to shares only upon vesting; they are not immediate purchases or sales and do not necessarily signal near-term trading. This grant increases potential future dilution when vested shares are issued, but no shares were sold or bought on the open market in this transaction.
