Builders FirstSource, Inc. (BLDR) valuation and DCF model

What the price implies · reverse DCF

At $62.59 the price implies free cash flow after share-based pay growing 18.5% a year for ten years.

Free cash flow after share-based pay grew 28.1% a year over the last ten years, 8.4% over the last five. The price asks for less than its ten-year rate. The industry’s median company is priced for 8.4%.

In December 2017 the price assumed 16.6% a year; Builders FirstSource, Inc. went on to grow free cash flow after share-based pay 29.2% a year to FY2025.

The headline discounts the last twelve months’ free cash flow after share-based pay at 9.0% for ten years and grows it 2.5% a year after that, the same for every company, so the figure compares across the market (how a reverse DCF works).

Its assumptions

Powerpack lets you start from a scenario and type over any of them.

The base case’s inputs, which Powerpack lets you change
1 · Cash flow to equity
the four quarters to September 2026, from the 10-Q and 10-K filings, before share-based pay

Yearly growth in cash flow. It usually slows as the company matures.

Today’s price implies free cash flow after share-based pay growing 18.5% a year for ten years.

2 · Rates

Cost of equity is the yearly return shareholders require, typically 8–11%. Terminal growth is growth forever after year 10, usually near long-run inflation, 2–3%.

3 · Per share

Diluted shares outstanding. Net debt, under Advanced inputs, is taken off before dividing.

BLDR trades at 176.44× P/E, against a 10-year average of 34.51× (range 3.89×–176.44×). That is dearer than 100% of the last 9 year-end readings; re-rating to the average implies $12.24 per share.

Every growth rate on this page is the business’s — its cash flow, FFO or dividend — never its share price’s. A discounted-cash-flow model is only as good as its assumptions. Figures from the 10-K and 10-Q filings. Not investment advice.
