  • The stock has been choppy recently, down 2.6% over the last week and 26.3% year to date, even though the 3 year and 5 year returns remain a solid 59.5% and 157.0% respectively.
  • Recent headlines have focused on the housing and renovation cycle, tighter financial conditions, and how material and labor dynamics could affect demand for building products. All of these factors feed directly into sentiment around Builders FirstSource. At the same time, analysts and investors are debating whether the market is pricing in too much macro pessimism relative to the company’s long term structural positioning in residential construction.

Find out why Builders FirstSource's -34.8% return over the last year is lagging behind its peers.

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

A Discounted Cash Flow model estimates what a business is worth by projecting its future cash flows and then discounting them back to today’s value. For Builders FirstSource, this approach focuses on the cash the company can return to shareholders over time rather than just today’s earnings.

The company generated about $996 million in Free Cash Flow over the last twelve months, in $. Analysts provide detailed forecasts for the next few years. Beyond that period, Simply Wall St extrapolates trends to build out a 10-year view. By 2035, those projections imply annual Free Cash Flow of just over $1.0 billion, still in $, reflecting moderate, steady growth rather than an aggressive expansion story.

Using a 2 Stage Free Cash Flow to Equity model, these projected cash flows translate to an estimated intrinsic value of about $114.02 per share. Compared to the current share price, this implies the stock is roughly 8.2% undervalued, which is close enough that it falls within a reasonable margin of error rather than a clear mispricing.

Approach 2: Builders FirstSource Price vs Earnings

For a profitable business like Builders FirstSource, the Price to Earnings, or PE, ratio is a straightforward way to gauge how much investors are willing to pay today for each dollar of current earnings. What counts as a reasonable PE depends on how quickly earnings are expected to grow and how risky those earnings are, with faster growth and lower risk usually justifying a higher multiple.

Builders FirstSource currently trades on a PE of about 19.5x, broadly in line with both the Building industry average of around 19.8x and the peer group average near 19.4x. At first glance, this suggests the market is valuing the company similarly to its closest comparables.

Simply Wall St’s Fair Ratio framework goes a step further. It estimates what PE multiple would be appropriate for Builders FirstSource given its specific growth outlook, profitability, industry, size and risk profile. On this basis, the stock’s Fair PE Ratio is 26.7x. The current 19.5x multiple therefore sits noticeably below what this model would expect for a business with these characteristics, which indicates potential upside if the company’s fundamentals evolve in line with those assumptions.
