FormFactor CEO Sells Despite 4-Quarter Earnings Streak
NEW YORK, August 18 —
FormFactor, Inc. (FORM) shares fell 10% on August 18 after SEC filings revealed CEO Mike Slessor had sold $2.1 million in stock four days prior, his third open-market selling episode since June, even as FormFactor's EPS accelerated from $0.33 to $0.82 across four consecutive quarters of analyst estimate beats.
- Q2 2026 EPS of $0.82 vs. $0.61 estimated (34.4% beat), per SEC 8-K filed July 29.
- CEO sold 16,002 shares August 14 at $128, $133 for $2.10M, his third open-market sale since June 10.
- Net 90-day insider activity: $0 in purchases, $6.33 million in sales; no insider bought shares.
The Selling Pattern
FormFactor makes probe cards, hardware that connects test equipment to semiconductor devices including GPUs, CPUs, and DRAM, for customers across Taiwan, South Korea, Japan, and the US. Slessor's June 10 sale of 11,890 shares at $117, $123 preceded the stock's summer rise. His July 15 sale of 4,735 shares at $116, $121 came before the quarter's largest beat. On August 7, he exercised options on roughly 157,375 shares and surrendered 78,908 in a tax-withholding disposition worth $9.26 million, then sold 16,002 more at $128, $133 a week later. Director Dennis Thomas also sold shares in May and June. No insider purchased a single share in the 90-day window.
What 35x Actually Requires
The beats are not marginal: FormFactor exceeded EPS estimates by at least 27% in each of the four quarters, per the July 29 SEC filing. Trailing twelve-month revenue reached $0.90 billion, up 31.9% year-over-year, with $115 million in free cash flow and $350 million in cash against only $30 million in debt. At a 35x forward multiple on trailing EPS of $1.45, the stock has priced in continuation; investors can stress-test that assumption with a DCF calculator. Consensus price targets sit at $138.60, roughly 14% above the August 18 close of $121.58.

The Question Slessor Hasn't Answered
The critical unknown is whether these sales operate under a pre-established 10b5-1 trading plan, an SEC-approved structure that pre-schedules insider transactions regardless of material non-public information. The filings do not specify. If a plan exists, the selling pattern is routine liquidation; if not, three open-market episodes coinciding with four earnings beats at an expanding multiple raises a distinct question about the CEO's read on the stock's risk-reward at these prices. The next earnings report will carry weight beyond the headline: sequential growth versus guidance will either validate the 35x multiple or provide the harder test this insider activity now demands.
