Is PLUG a buy according to UQS?

UQS rates PLUG as Poor at 28.4/100, driven primarily by Growth (72.8) as the sole above-average pillar. Quality and Valuation both score 0.0, reflecting an operating margin of -114.3% versus the sector median of 7.0% and deeply negative earnings metrics. The Poor label indicates broad fundamental weakness across the majority of the five-pillar framework.

What is PLUG's PEG ratio and what does it mean?

PLUG's PEG ratio is -0.06, which is not analytically meaningful in the conventional sense. The PEG formula divides P/E by earnings growth, but with negative earnings, the resulting figure cannot be interpreted as cheap or expensive relative to growth. The sector median PEG of 1.23 applies to profitable companies; PLUG's negative earnings base makes direct comparison uninformative until profitability is established.

Why might PLUG's UQS Score change?

The score recalculates daily using updated TTM financials and forward analyst estimates. Meaningful improvement would require gross margin turning positive — currently -34.1% — or a sustained reduction in operating losses. Downward revisions to forward revenue growth estimates (currently 34.2%) would pressure the Growth pillar, the only pillar above 50. Changes in debt levels or cash burn rate would also affect the Risk pillar score.

How is the PLUG UQS Score Calculated?

The UQS (Unified Quality Score) for Plug Power Inc. is calculated using a proprietary 6-pillar framework with 29 financial metrics. Each pillar evaluates a different dimension on a 0–100 scale, then combines into a single weighted score. Scoring thresholds are calibrated per sector. Momentum is an optional Pro toggle — without it, you get the 5-pillar / 25-metric core shown below.

Quality (25%) measures profitability and capital efficiency — ROIC, ROE, margins, GP/Assets, and FCF Yield.

Moat (25%) assesses Plug Power Inc.'s competitive advantages across switching costs, network effects, cost advantages, intangible assets, and ecosystem scale.

Growth (20%) tracks revenue trajectory and earnings momentum, combining historical results with analyst forward estimates.

Risk (15%) is inversely scored — lower leverage and strong balance sheet health result in higher scores.

Valuation (15%) measures whether Plug Power Inc. is fairly priced using earnings yield, price-to-FCF, PEG ratio, and EV/EBITDA relative to sector peers.

Six investor-inspired presets are available, each with different pillar weights: Balanced, Buffett, Munger, Lynch, Cathie Wood, and Graham. The public score shown here uses the Balanced preset. Learn more in our FAQ.
