Bowman Ronald Lee 4

What Happened
Ronald L. Bowman, Chief Human Resources Officer of QuidelOrtho Corp (QDEL), had 2,938 restricted stock units (RSUs) vest and convert into 2,938 common shares on January 29, 2026. To satisfy tax withholding obligations, 1,210 of those shares were surrendered at a withholding rate of $27.41 per share (total value withheld ≈ $33,166). The RSUs were granted at $0.00 (typical for RSU vesting).

Key Details

• Transaction date: January 29, 2026.
• Award/Acquisition: 2,938 RSUs vested and converted to 2,938 shares (code A and M; reported $0.00 per share).
• Tax withholding (disposition): 1,210 shares withheld at $27.41 per share → $33,166 (code F).
• Shares owned after transaction: not disclosed in this Form 4.
• Footnotes: F1–F4 indicate these were previously granted RSUs (each RSU = 1 share), 2,938 vested on 1/29/2026, and the remaining 5,878 RSUs vest in equal installments on 1/29/2027 and 1/29/2028; withholding was used to satisfy tax obligations.
• Filing timeliness: no late filing indicated in the Form 4.

Context
This was a routine RSU vesting and share-withholding to cover tax liabilities (a common, non-market-driven disposition). The filing shows conversion/exercise of RSUs (code M) and withholding (code F) rather than an open-market sale or new purchase. Such withholding actions generally do not signal new insider sentiment about the company's stock price.
