QuidelOrtho (QDEL) COO Philip D. McLellan Receives RSUs; Shares Withheld

What Happened

Philip D. McLellan, Chief Operations Officer of QuidelOrtho, had 4,897 restricted stock units (RSUs) vest on January 29, 2026. The RSUs converted into 4,897 common shares (acquisition at $0.00 per share). To satisfy tax withholding obligations, 2,017 of those shares were withheld (disposed) at $27.41 per share for a withholding amount of $55,286. That leaves a net delivery of 2,880 shares to McLellan.
The filing shows the RSU conversion (derivative exercise/conversion) and the tax-withholding disposition; the RSU conversion itself carries no cash exercise price.
