Builders FirstSource Inc

Builders FirstSource (BLDR) appreciated approximately 9% during the second quarter but remains down roughly 13% year-to-date amid continued weakness in the housing market. We expect 2026 free cash flow to be approximately $500–800 million, representing a 5–9% free-cash-flow yield. While housing activity remains near cyclical lows, we believe BLDR should be able to sustain this level of cash generation. The company has transformed its business, growing its higher-value-added operations to more than 40% of revenue, improving margins and making the business more resilient across the housing cycle. We believe new homebuilders are likely to continue gaining market share, benefiting BLDR significantly.

The housing sector continues to battle the affordability crisis driven by high interest rates, impacting BLDR's short-term stock performance. However, management's aggressive share repurchases and exceptional return on invested capital (>20%) keep us firmly convicted in the long-term thesis once the macro environment normalizes.

Builders FirstSource has fallen below $80, yet we believe the earnings potential of the business, its commanding position in its industry, and its ability to generate cash flows in excess of business needs remain intact. The market is currently focused on the probability of earnings compression over the next year or two, but as long-term investors, we believe the present value of future cash flows far exceeds the current trading price. We have seen this pattern before, where despite being a winner of the post-2008 housing consolidation, Builders FirstSource retraced nearly 50% from interim highs on several occasions. These pullbacks are not signs of failure but part of the investment process, and we are well positioned to capitalize going forward.

Builders FirstSource (BLDR) declined an additional 20% in the first quarter after a 28% decline in 2025 amidst weakness in the housing market. Fundamentally, the Company performed well last year and generated $875MM in free-cash-flow in 2025 translating to a trailing yield of ~10%. It seems likely that 2026 will be another year in this general range. Our long-term thesis remains intact as there is a structural shortage of housing in the USA. Higher mortgage rates reduce the supply of existing home supply as homeowners are locked into low-rate mortgages. As we have seen in recent history, the overall pie of housing activity may shrink, with new homebuilders capturing an increasing share of home sales.

America's housing shortage is a demographic fact, not a forecast, and the consolidation that reshaped building-products distribution after the financial crisis (Builders FirstSource for example) continues to compound value through the inevitable interim drawdowns. We are once again witnessing this reset today as Builders FirstSource trades in the 70’s. This presents a compelling opportunity as the underlying arithmetic of constrained supply and growing demand supports a favorable outlook for the company.

Builders FirstSource (BLDR) was one of the biggest detractors in the quarter, but one where we have continued faith. BLDR is the largest distributor of lumber and building products materials for contractors and home builders. The company has been a consolidator of smaller regional lumberyards over time and made a push towards increasing value-add building products such as pre-assembled trusses to save builders time and labor on the job site. We believe it’s early days in the housing market’s cyclical recovery and fundamental improvement. Moreover, BLDR’s chairman bought $55 million of stock in the summer. The company has also been a consistent acquirer of its own shares through buybacks, so the business checks two of the three capital allocation boxes we look for. The company should have considerable EPS upside when housing fundamentals improve, which is more likely now as interest rates are falling.

Builders FirstSource has demonstrated resilience and potential for growth, particularly as it has emerged as a key player in the building products distribution sector following the 2009 housing collapse. The company has navigated significant market fluctuations, retracing nearly 50 percent from interim highs on several occasions, which the manager views as part of a normal recovery process rather than a failure. The current market dynamics suggest that Builders FirstSource is well-positioned to capitalize on improving demand and rationalized competition, reflecting a strong earnings power that is often overlooked by the market.

We remain bullish on the long-term prospects for the homebuilding sector as we believe there is a shortage of housing and these companies trade for large discounts to their intrinsic values. We added to our position in both companies this quarter.

Our historic thesis on Builders FirstSource reads well today - as they navigate through a period of lower housing starts and lumber prices. We expect over time to own a greater percentage of this unique company as they opportunistically continue to shrink their outstanding shares. Since the inception of its buyback program in August 2021 through April 30, 2025, the Company has repurchased 99.3 million shares of its common stock, or 48.1% of its total shares outstanding, at an average price of $80.90 per share for a total cost of $8.0 billion. Builders’ Chairman Paul Levy personally purchased approximately $55 million of Builders shares in May 2025 at about $111/share - one of the largest personal insider purchases we have seen lately. We too think we have much upside potential in our Builders position from recent levels.

Builders FirstSource (BLDR) is positioned to benefit from a structural housing shortage in the USA, as higher mortgage rates limit existing home supply. The company has shifted focus to value-add products, which now account for over 40% of its revenue. Despite a downturn in Q1, BLDR maintained its 2025 outlook with targeted net sales of $16.05–17.05 billion and strong free cash flow projections. The company has sustained higher gross margins and is expected to generate a free-cash-flow yield of 9-13%, with growth potential from housing shortages and acquisitions. Their proactive stock buybacks signal confidence in long-term strategy.
