Mike Slessor, CEO of FormFactor (FORM), has demonstrated a consistent pattern of selling shares in the semiconductor company, with no recorded purchases across his 38 reported transactions. Since November 2025, Slessor has executed 13 sales totaling approximately $8.8 million, with the largest single transaction occurring on January 6, 2026, when he sold $2.57 million worth of FORM shares. His recent activity includes multiple sales clustered on specific dates, such as March 18, 2026, when he disposed of shares worth $271,107, $523,179, and $178,790, and February 18, 2026, with sales of $274,512, $463,648, and $77,437. The transactions also include smaller periodic sales, such as $185,398 and $235,291 on November 19, 2025.
Slessor’s filings indicate a mix of open-market sales (code "S") and transactions tied to equity awards (codes "F" and "M"), though the latter carried no reported value. His only other disclosed holding involves Berkshire Hathaway Energy (BHE), where a December 12, 2025, filing showed an acquisition with no associated dollar value. The absence of any buy transactions—particularly in FORM—suggests a sustained divestment strategy rather than accumulation. While the sales could represent routine portfolio management, the volume and frequency underscore a clear directional trend, with Slessor reducing his stake in FormFactor over the observed period.
