FORM
CEO on the sell side
FormFactor CEO Mike Slessor sold 11,204 shares of common stock on April 15, 2026, according to a Form 4 filing with the SEC. The shares went out the door in a handful of transactions at prices between $125.24 and $129.22, adding up to roughly $1.44 million.
The fine-print footnote matters
This wasn’t some surprise dump in the middle of the night. The filing says the sales were made automatically under a Rule 10b5-1 plan Slessor adopted back on August 19, 2025 — basically the corporate version of setting your vacation out-of-office reply months in advance. So yes, it’s insider selling, but no, it’s not necessarily a dramatic vote of no confidence.
Why investors are still watching
Even so, these trades land differently when the stock is trading around $129.67, near its 52-week high of $136, and after a monster 373% run over the past year. When a stock has already been doing cartwheels, any executive sale can make traders squint a little harder at the tape.
The bigger backdrop
FormFactor has had plenty going on besides this filing. The company also recently posted fourth-quarter 2025 results that beat expectations, and Cantor Fitzgerald even lifted its price target to $125 from $100 while keeping an Overweight rating. So the setup is a classic Wall Street mix: strong fundamentals, high expectations, and a CEO deciding to trim some chips off the table.
Big picture: this is more “taking some winnings off the board” than “run for the exits,” but after a huge rally, investors will be watching to see whether the stock can keep climbing without losing steam.
