Over the past six months (approximately April 2026 to October 2026), FormFactor's stock price has experienced significant movements, largely influenced by strong financial results and broader semiconductor industry trends, particularly related to AI demand, with the stock gaining 264.1% over the past 12 months to a closing price of $139.67 on October 9, 2026. On July 29, 2026, FormFactor reported strong Q2 2026 financial results, with adjusted EPS of $0.82 and revenue of $258.2 million, exceeding estimates and leading to a significant stock price surge due to robust demand in high-bandwidth memory (HBM), data center CPUs, and co-packaged optics, along with optimistic Q3 guidance. In August 2026, FormFactor announced participation in upcoming conferences to boost visibility. By September 2026, the stock continued to rally, fueled by investor optimism for AI-driven semiconductor test demand, and FormFactor announced participation in the 18th Annual CEO Investor Summit 2026, despite reports of insider selling by CEO Mike Slessor and a director which were noted as potentially routine or offset by bullish sentiment. In October 2026, FormFactor shares experienced fluctuations, including a decline alongside broader semiconductor and technology weakness due to surging Treasury yields, but also saw rebounds from strong AI-driven demand and continued institutional accumulation. FormFactor is scheduled to announce its Q3 2026 financial results on October 28, 2026, and was added to the S&P MidCap 400, replacing Twilio, while Workiva replaced FormFactor in the S&P 600, effective October 6, 2026.
