+30.3% margin of safety
As of 2026-07-29, the base-case DCF model estimates the intrinsic value of Regeneron Pharmaceuticals, Inc. (REGN) at $998.32 per share, compared with a market price of $695.42, a margin of safety of +30.3%. The base case assumes 12.9% annual free cash flow growth and a 10.0% discount rate.
Across the sensitivity grid the estimate spans $794.17 to $1,232.34. Intrinsic value is an estimate built on assumptions, not a fact. A higher discount rate or slower growth pushes the estimate down, while stronger cash flow growth lifts it.
How the DCF works · Recalculate with your own assumptions · What is intrinsic value?
At the current price of $695.42, REGN trades well below the base-case intrinsic value estimate, a margin of safety above 30%. By this model the stock looks undervalued, but verify the growth assumptions match your own view before acting.

Based on trailing twelve-month data, REGN shows a free cash flow per share of $40.19 and a ROIC of 8.5%, key inputs for stock valuation using the DCF method. The P/FCF ratio of 17.2x and FCF yield of 5.80% are important context metrics when evaluating REGN's stock valuation relative to peers.
Regeneron Pharmaceuticals, Inc. currently generates $40.19 in free cash flow per share. At the current price of $695.42, 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.
REGN trades at a P/FCF ratio of 17.2x with a free cash flow yield of 5.80%. This P/FCF is in a moderate range. However, whether REGN 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.
To perform a DCF valuation on Regeneron Pharmaceuticals, Inc.: (1) Start with the trailing free cash flow per share ($40.19) as the base, (2) project future FCF growth over 5-10 years based on Biotechnology industry trends and company fundamentals, (3) apply a discount rate (WACC) reflecting REGN's risk profile — with a debt-to-equity of 0.05x, capital structure is an important factor, and (4) add a terminal value for cash flows beyond the projection period.
DCF (Discounted Cash Flow) estimates what a company is worth today based on its future cash generation. For Regeneron Pharmaceuticals, Inc., this means projecting how much free cash flow the company will produce over the next 5-10 years, shaped by Biotechnology trends, then discounting those amounts to today's dollars. REGN's ROIC of 8.5% shows moderate capital returns.
WACC (Weighted Average Cost of Capital) is the discount rate in a DCF model — it reflects the minimum return investors require. For REGN, with a debt-to-equity ratio of 0.05x, the capital structure directly influences WACC. A 1% increase in WACC typically reduces the intrinsic value by 10-15%. At an EV/EBITDA of 13.5x, 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.
DCF and P/E value REGN with different methods and assumptions, so the two conclusions can differ. Compare the P/E fair value.
