What PDF Solutions does

PDF Solutions, founded in 1991 and headquartered in Santa Clara, California, serves the semiconductor industry with a mix of software, hardware and services. Its core Exensio platform gathers and analyzes data across manufacturing, process control, testing and assembly, helping chipmakers detect faults and trace issues across a product's life cycle. The Sapience products tie together data from diverse factory equipment and enterprise applications. Beyond analytics, the company sells Characterization Vehicle test chips with its pdFasTest electrical tester, the DirectScan eProbe non-contact e-beam tool, and Cimetrix and secureWISE software that give equipment makers standard ways to connect machines to factories. It operates in the United States, Japan, China and elsewhere, earning revenue from software licenses, SaaS, hardware and professional services.

What is PDF Solutions worth?

On an owner-earnings DCF, PDF Solutions's most-likely value is about $18 versus a recent price near $54 (67% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$3) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.

Verdict: Fairly priced — no edge

Owner-earnings fair value · recent price ≈ $54

Fair value (most likely)

$18

Range

$8–$52

No-growth floor

Price

~$54

Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.

Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
