Forward price target — the 1-year figure is the analyst consensus where the stock is covered; the 5- and 10-year figures compound our earnings estimate from there. The DCF below is a separate cross-check on intrinsic value (what it's worth today), not another target.

Why now
Electrical Equipment · market cap $2.9b. Down 54% from 52-week high of $4.58 — deep drawdown territory. Revenue growing +15%, comfortably above the S&P median.
Moat
Turnaround / out-of-favor name — GAAP-unprofitable for now, so the durability case is forward-looking: it rests on a recovery (margin normalization, a cyclical upturn or restructuring) or an un-monetized asset (IP / network effects / first-mover position) rather than on current reported results.
Risk
Free cash flow is negative (-$653m) — capital raises or debt issuance likely required; dilution / leverage risk. Currently unprofitable (margin -227.1%) — path to GAAP profitability is the core thesis risk. Down 54% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
Horizon
1-3 yr $2.82 (structural (no analyst coverage)) — catalyst-driven; binary events dominate. 5 yr $4.93 — requires the platform / technology to reach commercial scale. 10 yr $12.51 — return distribution heavily skewed.

Plug Power Inc (PLUG): score, valuation & FAQ

Plug Power Inc (PLUG) is a Electrical Equipment company that scores 18.3 out of 100 on the Bull Rankings quality-growth model — a weak reading. The score blends three pillars — quality (durable returns, healthy margins, low leverage), growth (revenue and earnings), and value (valuation versus sector peers) — into one number, refreshed daily; it is a screen, not a buy recommendation.

Is PLUG a good stock to buy?

Bull Rankings scores PLUG 18.3 out of 100 on its quality-growth model, which is a weak reading. That is driven by D/E (A-) and Rev (B+). A score is a quantitative screen of Plug Power Inc's fundamentals, not personalised financial advice — weigh it against your own time horizon and risk tolerance, and read the risk factors below before acting.

Why does PLUG score 18.3 on Bull Rankings?

The quality-growth score blends three pillars — quality (returns on capital, margins, leverage, earnings quality), growth (revenue and earnings expansion), and value (valuation versus sector peers). PLUG earns its highest marks on D/E (A-) and Rev (B+), and is held back by FCF (F). Each pillar is graded against sector-aware thresholds, then combined into the single 0–100 score.

Is PLUG overvalued or undervalued?

We don't compute a reliable discounted-cash-flow value for PLUG — typically because it is not yet consistently profitable or free-cash-flow positive — so its valuation rests on growth and price-to-sales rather than on earnings-based intrinsic value. Judge it on the trajectory of the business, not a single multiple.

What are the main risks of investing in PLUG?

Free cash flow is negative (-$653m) — capital raises or debt issuance likely required; dilution / leverage risk. Currently unprofitable (margin -227.1%) — path to GAAP profitability is the core thesis risk. Down 54% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
