CORNING INC /NY (GLW) Stock Analysis
CORNING INC /NY
▾ What's in the 36/100 risk score? (higher = riskier)
Contributions (weight × component score) sum to the total. This near-term score now includes fundamental health (leverage, FCF trend). It excludes the the Altman Z score, whose retained-earnings input this filer does not report separately, which relies on a proxied (estimated) input. See the Financial Health section for the full balance-sheet read.
How to read GLW
We are not publishing an intrinsic value for this one — the section below says exactly why. Everything on this page that comes straight from the filings and the tape is still here; treat the missing valuation as a known gap, not as a verdict on the business.
-
1
Reported earnings & margins ↓
What the company actually reported — unaffected by the valuation being held.
-
2
Balance sheet & book value ↓
Assets, liabilities and equity as filed.

Who's selling & betting against it ↓
Insider and short-interest behaviour needs no valuation model.
Our DCF for GLW lands well below today's price. For a non-cyclical that usually means the market is pricing in growth far beyond recent cash flows (or there's a data quirk), so we don't headline a single fair-value number.
What to use instead: The Reverse-DCF shows exactly how much growth the price demands — decide whether that's realistic. Pair it with peer multiples.
This note is only about the single DCF fair-value number — GLW's full financial statements, health scores, and written analysis are all below.
Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
We can't produce a trustworthy Altman Z here: retained earnings weren't separately reported in our data, so a core input would have to be fabricated. Rather than show a categorical "distress" verdict from an invented number, we mark it unavailable. Judge financial health from the leverage, cash position, and the measurable Piotroski checks instead.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak

Missing data is never counted as a pass or a fail — it's shown as n/a and excluded from the denominator. Each check compares the company against its own prior year.
What if you assume different inputs?
Here's where we land — and what happens if you change the assumptions. Drag the sliders to set your own Discount RateDiscount Rate — The annual return you demand for taking single-stock risk instead of buying a safe Treasury or index fund.
Why it matters: Higher discount rate = stricter valuation (a stock has to produce more cash to be worth holding). Lower = more generous.
Reference: 8–12% is standard · 9–10% matches S&P 500 historical return · Below 7% is illogical for single-stock risk

The discount rate starts at 10.0%, the figure our model used for GLW. Open Advanced to also change beta, growth and the rate path.
Note: no headline intrinsic value is published for this stock (the valuation is held for a data-quality reason — see the notes above). The calculator below is a what-if tool: the values it produces are your assumptions played out, not our estimate.
A full intrinsic value isn't shown for GLW because the valuation is currently held for a data-quality reason (see the guardrail notes above). The reverse-DCF reading still works — it needs only the price and cash flow — but we won't publish a forward value until the underlying data passes our checks.

A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for Corning Inc. because the model output failed plausibility checks, indicating potential data issues or that the market is pricing optionality and narrative catalysts beyond trailing cash flows. Investors are likely focused on future revenue growth and potential margin expansion rather than current free cash flowFree Cash Flow (FCF) — Operating cash flow minus capital spending: cash left after a company covers operating costs, taxes and interest and reinvests in the business — but BEFORE repaying debt principal or paying dividends. The cash actually available to investors.
Why it matters: A company can show big profits on paper while burning through cash. FCF is what actually fills the bank account.
Reference: Healthy mature businesses convert 8–15% of revenue into FCF · Growth companies often negative
Full explanation →. The biggest risk to our assumptions is that long-term debt has been rising significantly, from $55M to $804M, which could strain future financial flexibility.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What's free cash flow / what do these mean?
Revenue per share — how much the business earns from customers, divided by the number of shares outstanding. Top of the income statement.
Earnings per share — profit left after operating costs, interest, and taxes, per share. Two versions appear on this page and are not interchangeable: GAAP diluted EPS uses the company's weighted-average diluted share count during the reporting period (this is the "earnings" in "price-to-earnings"); net income per current share divides annual net income by today's share count. They differ whenever the share count has changed.
Owner-earnings free cash flow per share — the cash the business produces for shareholders. Savng's owner-earnings FCF subtracts capital expenditures and stock-based compensation from operating cash flow (SBC is a real dilution cost even though it's non-cash). This is deliberately more conservative than "standard" FCF, which subtracts only capital expenditures — so our figure is lower than the headline FCF you'll see elsewhere. FCF funds dividends, buybacks, debt repayment, and acquisitions; a company can report positive earnings yet negative FCF.
Debt per share — total interest-bearing borrowings divided by shares. High debt-per-share next to thin FCF-per-share is a fragility signal.
The trend, in plain numbers (2024 → 2025)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
- Revenue grew +19% to $15.63B.
- Free cash flow rose to $2.41B.
- Gross margin improved to 36% (+3 pts).
- Net income grew +215% to $1.60B.
Nothing clearly worsening year-over-year.

What we use instead: earnings (P/E, EV/EBIT), book value (P/B) — computed from the figures this company does report, shown in the sections below. Those numbers are unaffected by the missing cash-flow data.
The market is likely pricing Corning Inc. based on expectations for future growth in its various technology segments and potential margin expansion, rather than its current cash flow, which the model indicates is suppressed. The price is 6.8x the model's intrinsic valueIntrinsic Value — Our DCF model's estimate of what each share is mathematically worth based on projected cash flows.
Why it matters: Compare to current price. Below IV = potentially undervalued. Above IV = priced for growth that must actually happen.
Reference: Model-derived; quality depends on data and assumptions.

How They Make Money
Free Cash Flow DCF
Owner-earnings FCF DCF: positive free cash flow (operating cash flow − capex − stock-based comp) in a sector suited for cash-flow-based valuation. High P/FCF (59x) - market pricing significant growth.

What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project product, services and recurring/cloud lines independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.

Market Signals
These are timing signals, not value signals — they describe the stock's recent price behavior, not what the business is worth. Use them for the "the thesis looks good, but is now the moment?" question. Each tile below explains what it's saying.
Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.
Reference: 30–70 normal · >70 overbought · <30 oversold
Full explanation → (14)51.6NeutralMomentum is balanced — neither overbought nor oversold.
Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.
Reference: Line above signal = bullish momentum · below = bearish
Full explanation →BullishLine above signalThe fast trend is above the slow trend — short-term momentum is currently upward.
Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.
QUALITY
Data Quality & Risk Flags (4 notes — click to expand/collapse)
Guardrail Notes (4)
- Price is 6.8x model IV - market may be pricing optionality, narrative catalysts, or margin expansion beyond what trailing cash flows support.
- Extreme valuation: the price is far above the model output for a non-cyclical — likely dominated by a data issue. The model value is suppressed.
- VALUATION HELD (EXTREME_MODEL_GAP): per-share values suppressed due to the model output failed plausibility checks.
- Extreme valuation gap (P/IV null): result may be dominated by model assumptions, share count issues, or sector-specific dynamics. Treat as low confidence.
