The business, in plain English

PDF SOLUTIONS INC booked $219.0M of revenue in FY2025 in the Technology sector and kept 72.3% of it as gross profit — a high-margin business by that measure. After every other cost, −0.3% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $48.4M (FY2009) to $219.0M (FY2025) — about 9.9% a year compounded over 16 years.

It earned 1.3% on invested capital in FY2025, with a median of 6.8% across 13 filed years. The Returns on Capital filter above scores it 6/100.

The balance sheet carried $67.0M of total debt in FY2025. Balance-Sheet Safety scores it 21/100.

The share count rose 43.2% between FY2010 and FY2025 — existing owners have been diluted over the record. Capital Discipline scores it 24/100.

Put together: Pricing Power is the strongest of the four filters (90/100) and Returns on Capital the weakest (6/100), which is how PDFS lands at 38/100 — a None moat.
