Value diary

Our note on each quarter Builders Firstsource files

10-Q filed October 29: Builders Firstsource

Model value −1.7%

Builders Firstsource reported revenue of $14.4bn for the twelve months to September 2026, down 8.3% on a year earlier. That marks an improvement on the 9.4% decline seen a quarter earlier, though it still leaves the company 38th of 40 for growth among the building products firms we cover. Margins have thinned further: free-cash-flow margin dropped to 1.8% from 6.5%, while operating margin narrowed to 2.1% from 6.6%. A 3.6% reduction in the diluted share count has softened the blow for remaining holders. The fundamentals grade improves from D to C, even as our model value slips from $109 to $108 a share. Against a share price of $61.50, the rating stays Buy. At that price, the market appears to be pricing in cash flow shrinking roughly 4.7% a year for five years, not far off the -6.3% annual revenue decline actually delivered.

Highlights

How we pick these

Strengths

  • Priced below our value. The share price of $67.82 is 47% below our value per share of $100.
  • Shrinking share count. Diluted shares fell 3.6% in a year, so each share owns more of the business.

Things to watch

  • Margins narrowing. Operating margin is down 4.4 points on a year ago.
  • High earnings multiple. The shares trade at 182 times the last 12 months' earnings, so expectations are demanding.
  • Volatile shares. Over the past year the shares showed annualised volatility of 52% and a beta of 1.4 against the S&P 500.
  • Gross margin slipping. Gross margin is down 2.5 points on a year ago.
  • Below peers: long-term debt as % of assets. Long-term debt as % of assets of 40.7% ranks 33 of 37 building products companies we cover (median 25.7%).

Valuation

Builders Firstsource, Inc. valuation models and calculator

What the price is pricing in

The share price implies cash flow shrinking about 3.7% a year for five years.That is close to the -6.3% a year revenue growth Builders Firstsource has delivered.

  • Priced in-3.7%
  • Last 12 months-8.3%
  • 3 years a year-6.0%
  • 5 years a year-6.3%

Our cash-flow model with every input fixed except growth over the next five years, solved for the growth at which the model value equals the share price ($63.16, Nov 3, 2026). Cash-flow growth then fades to 2.5% a year; discount rate 8.5%. Delivered figures are revenue growth from SEC filings.

How we got here: a discounted-cash-flow model of Builders Firstsource, Inc.'s free cash flow after stock-based pay with after-tax interest added back ($957M, FY2026 Q3 TTM), growing 0.1% and 1.1% in the next two years (forecasts, guidance and its record), then back to 2% by year five, and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$64–~$150 ; that spread sets a 35% margin before we rate Buy or Sell.

Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Our value per share comes from a discounted-cash-flow model of Builders Firstsource, Inc.'s free cash flow after stock-based pay ( $957M, FY2026 Q3 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

Valuation models

We value Builders Firstsource, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 9.9%: the 10-year Treasury yield (4.9%) plus a beta of 1.1 times a 4.5% equity risk premium.

Options strategies

All options ideas

How Builders Firstsource, Inc.’s listed options are priced, and three ways to use them that follow from our valuation. Quotes are delayed, read November 3, 2026. Check the live chain at your broker before trading.

Implied vs realised volatility

Options look fairly priced

Implied volatility is within its normal range against realised. Selling options earns the usual premium, nothing extra.

  • Implied is 1.09× the last 60 days’ realised volatility , richer than 31% of the 175 stocks we screen today.
  • Calls are priced 4 points richer than puts (25-delta): demand for upside is high, which favours selling calls over puts.
  • Why: implied is not far enough above realised, or not unusual against our coverage.

Our rule for “rich”: implied at least 1.2× 60-day realised (beyond measurement noise), above 1-year realised (not just a calm spell), and in the top 20% of our coverage that day. Never with results inside the option’s life. These are our conventions, built on research showing option prices usually imply more movement than follows, most when the gap is wide. How we judge this.

Cash-secured put

Not offered: fundamentals grade C (needs B+ or better).

We suggest selling a put only on well-rated companies, at a strike where the price you would pay if assigned (strike less premium) is at or below our fair value.

Covered call

Not offered: no liquid call at or above our price target — the model says the upside is worth more than any listed strike.

For holders: sell a call at a strike at or above our fair value, so the shares are only sold at a price the model calls full value.

Collar

Not offered: the shares trade below our fair value: a collar caps upside the model expects.

For holders of a stock trading at or above our fair value: buy a put for a floor and sell a call to pay for it.

General research, not personal advice. Options can lose you more than you expect and are not suitable for everyone: put sellers can be made to buy shares that keep falling, call sellers give up gains above the strike, and results or news can move prices sharply. Chances shown are approximations from each option’s delta. Spreads, fees and early assignment are not modelled.

Growth, profitability, cash generation and balance sheet are percentiles against the companies we cover in the same industry, from SEC filings (100 = best).
