Siegrist Jonathan Philip 4

What Happened
Jonathan Philip Siegrist, EVP of R&D & CTO of QuidelOrtho (QDEL), had 2,448 restricted stock units (RSUs) vest on January 29, 2026. The RSUs converted into 2,448 common shares (conversion/derivative event); the issuer withheld 1,009 of those shares to satisfy tax withholding obligations at $27.41 per share (withholding value reported as $27,657). Because the RSUs converted at $0 exercise price, no cash was paid for the conversion. Net shares delivered to Siegrist after withholding: 1,439 shares.

Context

• This was not an open-market sale or purchase by the insider but a routine issuance (RSU vesting) with a cashless share withholding to cover taxes.
• The derivative code (M) here reflects conversion/exercise of RSUs into common shares at no out-of-pocket exercise price.
• Such withholding transactions are standard for equity compensation and do not necessarily indicate a buying or selling signal about the insider’s view of the company.
