Meridian Contrarian Fund stated the following regarding PDF Solutions, Inc. (NASDAQ:PDFS) in its Q2 2026 investor letter:

"PDF Solutions, Inc. (NASDAQ:PDFS) is a data analytics company serving the semiconductor industry through a proprietary combination of software, hardware, and services. The company's platforms deliver manufacturing analytics to fabs, fabless designers, equipment makers, and test companies, enabling customers to substantially improve production yields and reduce development costs. PDFS underwent a significant business model transformation around 2019, leveraging AI to convert decades of consulting expertise into scalable, recurring software products — a transition that meaningfully improved the company's long-term economics. A subsequent earnings decline in late 2023 and early 2024, driven by a cyclical end market downturn and investment spending on a new inspection product, created an attractive entry point. We invested based on our view that PDFS's yield improvement tools will become increasingly valuable as semiconductor complexity and development costs continue to rise — a structural tailwind that we believe is still in its early stages. PDFS delivered strong results during the quarter, with positive earnings complemented by broad market enthusiasm for the semiconductor sector. We trimmed our position into strength consistent with our standard risk management discipline but remain investors based on our positive view of the company's long-term growth outlook."
