Frequently Asked Questions
What is the intrinsic value of MLM?
Martin Marietta Materials, Inc. currently generates $17.15 in free cash flow per share. At the current price of $569.66, 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 MLM undervalued?
MLM trades at a P/FCF ratio of 33.1x with a free cash flow yield of 3.02%. This P/FCF is in a moderate range. However, whether MLM 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 MLM stock using DCF?
To perform a DCF valuation on Martin Marietta Materials, Inc.: (1) Start with the trailing free cash flow per share ($17.15) as the base, (2) project future FCF growth over 5-10 years based on Construction Materials industry trends and company fundamentals, (3) apply a discount rate (WACC) reflecting MLM's risk profile — with a debt-to-equity of 0.50x, 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 MLM?
DCF (Discounted Cash Flow) estimates what a company is worth today based on its future cash generation. For Martin Marietta Materials, Inc., this means projecting how much free cash flow the company will produce over the next 5-10 years, shaped by Construction Materials trends, then discounting those amounts to today's dollars. MLM's ROIC of 6.1% means the company's return on invested capital sits below the level that typically clears its cost of capital.
How does WACC affect MLM stock valuation?
WACC (Weighted Average Cost of Capital) is the discount rate in a DCF model — it reflects the minimum return investors require. For MLM, with a debt-to-equity ratio of 0.50x, the capital structure directly influences WACC. A 1% increase in WACC typically reduces the intrinsic value by 10-15%. At an EV/EBITDA of 18.5x, 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.
