Rosenbaum Marc Wade 4

What Happened

• Marc Rosenbaum, Chief Accounting Officer of iRhythm Holdings (IRTC), was granted 2,508 restricted stock units (RSUs) on February 25, 2026. The Form 4 reports the acquisition at $0.00 per unit (typical for equity awards); total cash paid was $0. This is a compensation grant rather than an open-market purchase or sale.

Key Details

• Transaction date: 2026-02-25; transaction type: Award/Grant (code A); reported price: $0.00.
• Shares/units granted: 2,508 RSUs. Filing does not disclose total shares owned after the grant in the provided summary.
• Vesting: Per the filing footnote, 25% of the RSUs vest on March 1, 2027, with the remainder vesting in equal installments on each one-year anniversary thereafter, subject to continued service.
• Filing timing: Report filed 2026-02-27 for a 2026-02-25 transaction — within the typical two-business-day Form 4 window and appears timely.
• No 10b5-1 plan, tax-withholding sale, or immediate sale noted in the filing.

Context

• RSUs are a common form of equity compensation that convert to shares only upon vesting; they do not require a cash purchase by the insider and do not represent immediately tradable shares until vested. Such grants are standard for executive compensation and should be interpreted as a company compensation event rather than a direct insider buy/sell signal.
