What Happened
Kenneth F. Buechler, a director of QuidelOrtho Corporation (QDEL), had 6,829 restricted stock units vest on May 29, 2026 and those units were converted into 6,829 shares. The Form 4 reports the acquisition and the conversion at $0.00 per share (the filing shows a non-cash award/vesting event, not an open-market purchase or sale).

Context
This was a routine vesting and conversion of previously granted restricted stock units into common shares (M = conversion of derivative; A = acquired shares). The $0.00 amounts reflect the mechanics of the award conversion in the Form 4, not the market value of the shares. Such vesting events are common compensation for directors and do not, by themselves, indicate a buy or sell signal from the insider.
