Busky Joseph M. 4

What Happened

• Joseph M. Busky, Chief Financial Officer of QuidelOrtho Corporation (QDEL), had 4,925 restricted stock units (RSUs) release/convert into 4,925 common shares on March 28, 2026 (reported as an award/acquisition).

Context

• This was not an open-market sale but a standard RSU vesting with share withholding to cover taxes (a routine administrative action, not necessarily a market sentiment signal).
• The filing shows conversion of RSUs into shares with a portion withheld (cashless share withholding), not a voluntary sale by the insider.
