About FORMFACTOR INC
FormFactor Inc. is a U.S.-based semiconductor test-and-measurement company listed on the Nasdaq Stock Market (NASDAQ: FORM) in the United States. Founded in 1993 by Tom Khandros, the company has established itself in a highly specialized niche of the semiconductor value chain: wafer probing, characterization, modeling, reliability, design debug, qualification, and production test. Its headquarters are in Livermore, California, placing it within one of the key technology hubs in the United States. ([investors.formfactor.com](https://investors.formfactor.com/static-files/3ab0bc87-0070-41f7-b0d0-364f267d7ee8?utm_source=openai)) Operationally, FormFactor reports two segments: Probe Cards and Systems. The Probe Cards segment includes advanced probe cards and related wafer test solutions used to electrically test integrated circuits during manufacturing. The Systems segment covers probe stations and a broader portfolio of test and measurement tools, including metrology, thermal, and cryogenic systems. This structure gives the company exposure to multiple end markets, from memory manufacturers to foundry and logic customers, as well as research and specialized test environments. ([investors.formfactor.com](https://investors.formfactor.com/static-files/fdd06538-d30a-46ec-b49d-e2e5c63db6f2?utm_source=openai)) Its product portfolio is built around technically demanding applications. FormFactor offers probe card platforms for DRAM, high-bandwidth memory (HBM), and foundry/logic devices, along with analytical probes and probe station systems such as the EVOLVITY family. The company also highlights RF, DC, mixed-signal, and optical probing solutions, which underscores its relevance in high-precision and high-frequency test applications. From a competitive standpoint, FormFactor positions itself as a leading supplier in semiconductor test subsystems and focused chip-making equipment, a segment where customer qualification, technical performance, and process reliability are critical barriers to entry. ([formfactor.com](https://www.formfactor.com/products/probe-cards/?utm_source=openai)) FormFactor has an international commercial footprint, serving semiconductor customers across Asia, North America, and Europe, although the company remains structurally exposed to the semiconductor cycle and to geopolitical and trade-related risks, including U.S.-China export restrictions and tariff volatility. In its February 2026 fiscal 2025 results, FormFactor reported record annual revenue of $785.0 million, supported by growth in HBM-related demand, and noted stronger second-half non-GAAP gross margin performance. Management also pointed to continued demand in advanced packaging and high-performance computing, while increasing capacity and working toward additional operational improvements as the Farmers Branch site comes online toward the end of 2026.
