FormFactor shares fell 15.29% to close at $95.03, marking a sharp decline in the semiconductor test equipment sector. The move coincided with a broader rout in peers including Applied Materials, Lam Research, KLA Corporation, and Penguin Solutions. This drop extends a recent trend, with the stock down 25.8% over the last eight sessions.

What Happened

The primary catalyst for the session was a sector-wide sell-off that affected multiple major semiconductor equipment manufacturers. While FormFactor announced the opening of a new U.S. probe card facility in Farmers Branch, Texas, to expand capacity for advanced packaging, the positive news did not offset the broader market pressure. The company positioned the new site as a milestone to support growing demand for advanced probe card technologies and improve operational flexibility.

Despite the operational expansion, the stock faced headwinds from valuation concerns and recent price target adjustments. B. Riley cut its price target on FormFactor to $150 from $165, maintaining a Buy rating. The stock’s decline brought it closer to its 52-week low, having printed 42 fresh 52-week lows on October 22, 2026.

What The Data Shows

Fundamentals indicate a high-growth profile with revenue up 18.0% year-to-date and a net margin of 12.8%. However, the valuation remains elevated with a P/E ratio of 65.6 and a market cap of $8.8 billion. The stock’s beta of 1.18 suggests higher volatility relative to the broader market.

Insider activity has been predominantly negative over the last 90 days, with four sales totaling $5.5 million and no purchases. CEO Mike Slessor sold shares on October 14, 2026, and September 16, 2026, while director Steven-Waiss Kelley sold on September 3, 2026. Congressional trading data shows mixed activity, with two buys and two sells disclosed in the last 90 days, including recent sales by Donald J. Trump in July 2026.

What To Watch

Investors will monitor how the new Farmers Branch facility impacts future capacity and whether the stock can stabilize after the recent 25.8% decline. The sector’s reaction to advanced packaging demand and any further analyst adjustments will be key factors in the near term.
