Equity compensation analyst

Routine RSU grant to CFO with quarterly vesting through 2028.

FormFactor granted 13,188 RSUs to its CFO on November 6, 2025. RSUs are equity awards that convert into shares upon vesting; this grant carries a stated price of $0 per unit and is held directly.

The vesting cadence—twelve quarterly installments from February 6, 2026 to November 6, 2028—aligns incentives over a multi‑year period and ties realization to continued service. Unvested units are forfeited upon termination, subject to pre‑filed agreements, which is standard.

This is a routine executive compensation event. Actual share issuance occurs over time as tranches vest; any market impact depends on future vesting and delivery under the disclosed schedule.
