Approach 1: Builders FirstSource Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth by projecting its future cash flows and then discounting those back to today’s value using a required return.

For Builders FirstSource, the model uses a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month Free Cash Flow is about $835.4 million. Analysts provide specific forecasts out to 2029, with Simply Wall St extending those projections further, including an estimated Free Cash Flow of $1,342.5 million in 2035.

When all those projected cash flows are discounted back to today, the model arrives at an estimated intrinsic value of about $131.98 per share. Against the recent share price of around $78.85, this implies the shares trade at roughly a 40.3% discount to that DCF estimate. This suggests there is a meaningful gap between the current share price and the value indicated by this particular valuation model.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Builders FirstSource is undervalued by 40.3%. Track this in your watchlist or portfolio, or discover 62 more high quality undervalued stocks.

Approach 2: Builders FirstSource Price vs Earnings

For a profitable company, the P/E ratio is a useful way to see how much investors are paying for each dollar of earnings. What counts as a normal or fair P/E tends to rise when the market expects stronger earnings growth and falls when investors see higher risk or more volatile results.

Builders FirstSource currently trades on a P/E of about 20.0x. That sits above the Building industry average of roughly 19.2x and also above the peer group average of about 18.2x, which indicates the market is paying a higher multiple than these broad benchmarks.

Simply Wall St’s Fair Ratio for Builders FirstSource is 34.7x. This is a proprietary estimate of what the P/E might be given factors such as the company’s earnings growth profile, industry, profit margins, market cap and risk characteristics. Because it folds these elements into one figure, the Fair Ratio can offer a more tailored yardstick than a simple comparison with peers or the industry average. Set against the current P/E of 20.0x, the Fair Ratio suggests the shares trade below that model based estimate.
