FormFactor NASDAQ:FORM said that CEO Mike Slessor sold a total of 8,664 shares of common stock on February 18, 2026. The dispositions were executed in three separate trades and carried out under an established 10b5-1 plan.

The three transactions spanned prices from $92.85 to $94.79 and brought in a total of $815596. The breakdown of the trades is as follows:

  • The first sale comprised 834 shares at a weighted average price of $92.85, with individual execution prices ranging from $92.375 to $93.36.

Separately, FormFactor reported fourth-quarter 2025 financial results that topped Wall Street forecasts. The company posted earnings per share of $0.46 versus an expected $0.35, representing a surprise of 31.43%. Revenue for the quarter was $215.2 million, ahead of the projected $210.25 million. These results indicate that the company outperformed analyst estimates on both the EPS and top-line measures for the quarter.

Despite the earnings and revenue beats, the companys shares declined during regular trading hours following the release, before registering a modest recovery in after-hours trading. The market reaction highlights a divergence between reported financial performance and investor trading behavior in the immediate session.

Observers will continue to monitor FormFactor's subsequent performance in coming quarters as the market digests both insider activity and the recent quarterly results. The company's reported figures and the insider sales provide concrete data points for investors and analysts tracking equity movements and corporate disclosures.

Risks

  • Market reaction risk - despite better-than-expected quarterly results, the stock declined in regular trading which indicates near-term volatility in equity markets.
  • Insider transaction interpretation - the CEO's sales under a 10b5-1 plan may be routine, but such activity can introduce uncertainty among investors tracking insider behavior.
  • Earnings momentum uncertainty - while Q4 2025 results beat estimates, future quarters are not discussed in the report, leaving subsequent performance outcomes uncertain.
