What Happened Susan D. Lynch, a director of Onto Innovation, was granted 761 restricted stock units (RSUs) on May 20, 2026.

The grant represents a contingent right to receive one share of ONTO common stock per RSU; 100% of the RSUs vest one year from the grant date.

Key Details

• Transaction date: 2026-05-20; Form 4 filed 2026-05-22 (filed within two business days, appears timely).
• Grant: 761 RSUs; acquisition price reported as $0.00.
• Vesting: 100% vests one year from the grant date (expected vesting ~2027-05-20).
• Deferral: Lynch elected to defer settlement under the Onto Innovation Nonqualified Deferred Compensation Plan; shares will be issued per that deferral election once vested.
• Shares owned after transaction: not specified in the provided filing.

Context RSU grants are a common form of director compensation and represent a future right to receive shares upon vesting. Because Lynch elected deferred settlement, the award does not result in immediate share issuance. This is an award (not an open-market buy or sale) and should be read as compensation rather than a direct buy/sell signal.
