Frequently Asked Questions
What is the intrinsic value of GLW?
Corning Inc currently generates $2.78 in free cash flow per share. At the current price of $149.79, a DCF model would discount these cash flows at an appropriate WACC and apply a terminal growth rate to arrive at an intrinsic value. The result depends heavily on your growth and discount rate assumptions — a 1% change in WACC typically shifts the fair value estimate by 10-15%. In MiniValuator the model uses a single discount rate that you can edit directly, 10% by default, rather than a computed WACC.
Is GLW undervalued?
GLW trades at a P/FCF ratio of 53.9x with a free cash flow yield of 1.86%. A high P/FCF means investors are paying more per dollar of free cash flow, which usually reflects expectations of future growth. However, whether GLW is truly undervalued requires comparing the DCF intrinsic value to the current market price and evaluating whether the margin of safety is sufficient for your risk tolerance.
How do I value GLW stock using DCF?
To perform a DCF valuation on Corning Inc: (1) Start with the trailing free cash flow per share ($2.78) as the base, (2) project future FCF growth over 5-10 years based on Hardware, Equipment & Parts industry trends and company fundamentals, (3) apply a discount rate (WACC) reflecting GLW's risk profile — with a debt-to-equity of 0.75x, capital structure is an important factor, and (4) add a terminal value for cash flows beyond the projection period.
What is DCF valuation and how does it apply to GLW?
DCF (Discounted Cash Flow) estimates what a company is worth today based on its future cash generation. For Corning Inc, this means projecting how much free cash flow the company will produce over the next 5-10 years, shaped by Hardware, Equipment & Parts trends, then discounting those amounts to today's dollars. GLW's ROIC of 8.2% shows moderate capital returns.
How does WACC affect GLW stock valuation?
WACC (Weighted Average Cost of Capital) is the discount rate in a DCF model — it reflects the minimum return investors require. For GLW, with a debt-to-equity ratio of 0.75x, the capital structure directly influences WACC. A 1% increase in WACC typically reduces the intrinsic value by 10-15%. At an EV/EBITDA of 34.8x, the market's implied discount rate can be reverse-engineered for comparison. In MiniValuator you set this discount rate yourself as a single editable number, 10% by default, instead of computing a formal WACC.
