SLESSOR MIKE 4

What Happened

• Mike Slessor, CEO and director of FormFactor (FORM), had restricted stock units (RSUs) convert into 9,675 shares on Feb 5–6, 2026. To satisfy tax withholding, 5,452 of those shares were withheld (disposed) for aggregate consideration of $478,812 (2,095 shares at $83.87 = $175,708; 3,357 shares at $90.29 = $303,104). Net shares added to his position after withholding: 4,223 shares.
• These were RSU settlements (conversion of derivatives), not open-market sales. The zero-dollar “acquired/disposed” derivative lines reflect the RSU-to-share conversion.

Key Details

• Transaction dates and prices: Feb 5, 2026 (3,644 RSUs converted; 2,095 shares withheld at $83.87); Feb 6, 2026 (6,031 RSUs converted; 3,357 shares withheld at $90.29).
• Shares acquired via settlement: 9,675; shares withheld for taxes (treated as disposition): 5,452; net new shares retained: 4,223.
• Total value of shares withheld for taxes: $478,812.
• Footnotes: RSUs settle 1-for-1 into common stock. Withholding shares were used to cover tax obligations. The grants vest quarterly (Aug 5, 2024 grant vests Nov 5, 2024–Aug 5, 2027; Aug 6, 2025 grant vests Nov 6, 2025–Aug 6, 2028). Unvested RSUs are forfeited upon termination except as provided in certain agreements.
• Filing: Form 4 was filed Feb 9, 2026 — within the typical 2-business-day reporting window for these Feb 5–6 transactions.

Context

• This is a routine RSU vesting and tax-withholding event, not an open-market sale that signals active divestment. When RSUs vest, companies commonly withhold shares to satisfy tax liabilities (a net-share settlement), which reduces the number of shares the insider takes away from the vesting event.
• For retail investors: such transactions document insider share changes but do not necessarily reflect a buy-or-sell signal about company prospects.
