Stock analysis

PDF Solutions Inc (PDFS) currently trades at $41.00, while our model-based Fair Value estimate is $2.51, 93.9% below the price, so the stock looks overvalued today.

Valuation

Bull case: the Multiples group reads highest at a median of $2.51 per share, and 0 of the 4 models we run sit above the $41.00 price.

Bear case: the Asset-Based group reads lowest at $0.3800, and 4 of the 4 models stay below the price. Data coverage for this calculation is low.

Scenario range: $1.68 (bear) to $3.34 (bull), the price of $41.00 sits above it. Bear and bull are the same models on cautious and optimistic assumptions, a range, not a price target.

Quality & growth

The Quality Score stands at 41/100 (below-average quality), in the Technology sector.

Expensive Growth: The company is growing, but growth may require heavy reinvestment or weak cash conversion.

Key figures

Market cap $1.7B Small · P/E ratio 164.0 · P/S ratio 7.10 · EPS (TTM) $0.2500 · Net margin 4.3% · Return on equity 3.3% · Return on assets (EBIT) −1.3% · Operating margin 8.2%.

Competitive moat

Our AI-assisted moat analysis scores the competitive advantage at 34 out of 100 (low confidence).

What moves the price

The last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat.

The share trades about 42% below its 52-week high and 71% above its 52-week low, currently below its 200-day average.

For context, the median of 10 Technology peers we cover trades at −18% fair-value upside, at −94%, PDFS screens richer than that median.

Fair Value models

Bear $1.68 Fair Value $2.51 Bull $3.34

Price $41.00 · Downside -93.9%

Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then ($0.2096 per share) are deliberately not added. Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds. Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.
