Company snapshot — PDF Solutions Inc

PDFS in five paragraphs: what it makes and sells, where it sits in the Closelooknet stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
PDF Solutions builds software, intellectual property and measurement tools that chipmakers use to analyse and improve manufacturing yield. Its Exensio suite covers process control, test operations and assembly data, while Cimetrix and Sapience products connect factory equipment and data systems, and DirectScan and Characterization Vehicle tools gather electrical measurements from wafers. Customers are chip designers and fabs that need to find and fix yield problems across the production line. It is based in Santa Clara, California.
Where it sits in the stack
In our Rubin Build-Out 100 index, PDF Solutions sits in Layer 3, Assembly & Test, within the Testing & Metrology sleeve — the group of ATE testers, inspection and metrology vendors that keeps yield curves honest as nodes shrink. Unlike the testers in that sleeve, it supplies the software and data layer that turns their measurements into yield decisions, making it a customer of the sleeve's physical tools as much as a constraint on how fast fabs can act on test data.
Who it is priced against
Closelooknet's peer group places it with the Testing & Metrology sleeve, alongside Teradyne, Onto Innovation, KLA, Camtek, Cohu, Nova and Aehr Test Systems; the market also names Synopsys as a comparable name in yield and design software.
Why Closelooknet tracks it
PDF Solutions holds a seat in the Rubin Build-Out 100 and carries a Closelooknet score, with momentum its strongest module and valuation its weakest; the diary has not yet quoted it directly.
What the diary watches
Whether demand for yield-analytics software tracks the pace of new node ramps and rising AI chip volumes, or lags the physical testing tools it depends on for data.

PDF Solutions Inc (PDFS) trades on US exchanges, classified under Technology, and sits in Layer 3 of the build-out stack. Constituent of Rubin Build-Out 100.

The Closelooknet company score reads 43/100 composite (momentum 49, quality 31, valuation 16) across 7 modules — the full breakdown, chart structure and analog history load live above.

Dividends and capital return

What PDFS pays out and buys back — distributions read from the price series, money terms from the filings.

  • Distributions No cash distribution recorded in the price series over the last three years
  • Buybacks, FY2025 244,000 USD 0.0% of today's market value
  • Share count +0.7% in FY2025 26 m USD of stock-based compensation in the year
  • Capital returned 244,000 USD in a year of negative free cash flow dividends and buybacks together

Per-share amounts are derived from the adjusted price series in the listing currency, so dates sit within days of the ex-date; filing figures come from the fundamentals feed for the last reported fiscal year. An investment diary, not a recommendation.
