About Formfactor INC

FormFactor Inc. is a U.S.-based semiconductor test and measurement company listed on the NASDAQ under the ticker FORM. Headquartered in Livermore, California, in the United States, the company plays a specialized but strategically important role in the semiconductor value chain. Its products sit at the interface between chip design and high-volume manufacturing, helping customers characterize, validate, debug, qualify, and production-test increasingly complex integrated circuits. For investors, FormFactor is best understood as a mission-critical equipment supplier whose demand is closely linked to semiconductor capital spending, memory technology cycles, advanced packaging, AI infrastructure, and high-performance computing. ([investors.formfactor.com](https://investors.formfactor.com/news-releases/news-release-details/formfactor-inc-reports-2025-fourth-quarter-results?utm_source=openai)) Founded in the late 1990s, FormFactor built its franchise around wafer-level probing and test interfaces, especially probe cards and probe stations. Over time, it evolved from a niche test-solutions provider into a broader semiconductor test-and-measurement platform. That history matters because the company’s competitive edge is rooted in deep application engineering, long customer relationships, and high switching costs. Semiconductor customers rely on these tools to improve yield, reduce time-to-market, and manage the risk of introducing new process nodes or packaging architectures. In practical terms, FormFactor benefits when device complexity rises, because more advanced chips require more sophisticated test coverage. ([investors.formfactor.com](https://investors.formfactor.com/news-releases/news-release-details/formfactor-inc-reports-2025-third-quarter-results/?utm_source=openai)) The company’s core business remains centered on semiconductor test solutions, with a portfolio spanning probe cards, probe stations, RF measurement solutions, and related systems used across characterization, reliability, design debug, qualification, and production. In addition to its legacy strengths in memory and foundry test, FormFactor has been extending its reach into adjacent high-value areas such as silicon photonics, co-packaged optics, and quantum/cryogenic hardware. In March 2026, it introduced the Flatiron dilution refrigerator for benchtop millikelvin research and quantum hardware validation, underscoring a broader technology optionality beyond conventional semiconductor test.

That positioning reflects its reputation for precision, customization, and reliability, as well as its footprint across major semiconductor regions worldwide. While the company is firmly anchored in the United States, its customer base is global, spanning leading chipmakers, foundries, memory manufacturers, and research-oriented end markets. ([formfactor.com](https://www.formfactor.com/press-release/formfactor-named-1-global-supplier-in-test-subsystems-and-focused-chip-making-equipment/?utm_source=openai)) Recent developments have been notably constructive. FormFactor reported record fiscal 2025 revenue in February 2026 and followed with another record quarter in April 2026, highlighting especially strong demand in HBM-driven DRAM and improved momentum in Foundry & Logic, including networking-related probe card demand. The company also announced the acquisition of Keystone Photonics in December 2025 to strengthen its silicon photonics and co-packaged optics test capabilities, a timely move given the growth of AI data-center infrastructure. Separately, it began site work and equipment installation for a new advanced manufacturing facility in Farmers Branch, Texas, signaling continued investment in capacity and operational scale. Overall, FormFactor offers exposure to advanced semiconductor test spending with a differentiated technology profile and an increasingly diversified growth runway.
