About PDF Solutions, Inc.
About PDF Solutions, Inc.
PDF Solutions derived 53% of its 2025 revenue from just three customers, reflecting the company's historical reliance on a small number of large semiconductor manufacturers for its data analytics and yield-improvement platform. The company's Cimetrix connectivity products shipped embedded on nearly 8,000 pieces of semiconductor manufacturing equipment in 2025, while its secureWISE network, expanded through a 2025 acquisition, connects over 300 manufacturing locations and more than 100 equipment OEMs across eight global regions.
PDF Solutions earns Platform revenue from software licenses, SaaS subscriptions, engineering services, and Characterization Vehicle (CV) system fixed fees, plus Volume-based revenue tied to Cimetrix runtime licenses, secureWISE data, and CV system royalties (Gainshare) that scale with customer wafer volumes. The company's Exensio software provides manufacturing analytics, process control, test operations, and assembly-operations modules for integrated device manufacturers, fabless companies, foundries, and OSATs, while its DirectScan system, combining proprietary eProbe hardware with Fire software, performs contactless e-beam inspection to catch defects inline. PDF Solutions holds 209 U.S. patents as of December 31, 2025, with expirations ranging from 2027 through 2043, protecting its CV, DirectScan, and AI/ML-related inventions.

PDF Solutions' own risk factors disclose that three customers accounted for 53% of 2025 total revenue, a concentration the company says exposes it to reduced revenues if any one customer defaults, consolidates, or decides not to engage PDF Solutions on a future process node; a 2019 dispute with SMIC New Technology Research & Development over unpaid fees, which cost the company $2.5 million in legal fees in the fourth quarter of 2025 alone, illustrates the downside of that dependence. Compounding that customer risk, PDF Solutions relies on sole-source providers for certain licensed software and specialized DirectScan system components, an exposure the company says would be difficult or costly to replace if any single-source vendor delayed or discontinued supply.
