Third Quarter 2026 Highlights
All Year-Over-Year Comparisons Unless Otherwise Noted:

• Net sales were $3.9 billion, a decrease of 2.2%, primarily due to a lower housing starts environment and related headwinds. The decline reflects lower core organic net sales as well as commodity deflation, partially offset by growth from acquisitions.
• Gross profit was $1.1 billion, a decrease of 10.6%. Gross profit margin percentage decreased 260 basis points to 27.8%, primarily driven by a lower housing starts environment and related headwinds.
• Net income was $60.4 million, or diluted EPS of $0.56 compared to diluted EPS of $1.10 in the prior year period. Net income as a percent of net sales decreased by 150 basis points to 1.6%.
• Adjusted EBITDA decreased 28.3% to $311.1 million, primarily driven by lower gross profit.
• Adjusted EBITDA margin declined by 290 basis points to 8.1%, attributable to lower gross margin and reduced operating leverage.
• Cash provided by operating activities was $146.6 million, a decrease of $401.2 million compared to the prior year period. The Company's free cash flow was $76.0 million, a decrease of 83.7%, compared to $464.9 million in the prior year period. The decrease was primarily driven by lower net income and higher net working capital, partially offset by lower capital expenditures.

“Our third quarter results reflect the disciplined execution of our team and the resilience of our platform. While housing market conditions remain challenging, we are focused on what we can control: delivering solutions that help builders operate more efficiently and investing in value-added products and technology to drive productivity and fuel growth. These efforts are reinforcing our leadership position and our role as the partner of choice for homebuilders,” commented Peter Jackson, CEO of Builders FirstSource.

Mr. Jackson continued, “This environment underscores the importance of operational excellence and differentiated capabilities at scale. Our investments in value-added offerings and technology strengthen our competitive advantages and position us to outperform as housing market conditions improve.”

Pete Beckmann, CFO of Builders FirstSource, added, “Our third quarter results met our expectations, reflecting solid execution and a sustained focus on cost management. Based on our year-to-date performance, we are narrowing our full-year outlook and maintaining the midpoints for net sales and Adjusted EBITDA as we enter the final quarter. Our strong capital position and solid cash flow generation give us the capacity to pursue growth opportunities while maintaining financial flexibility.”

All Year-Over-Year Comparisons Unless Otherwise Noted:

Selling, General and Administrative Expenses

• SG&A was $973.2 million, an increase of $2.5 million, or 0.3%, primarily driven by additional expenses from operations acquired within the last twelve months and higher fuel and insurance expenses, partially offset by lower variable compensation as a result of decreased net sales and lower wages as a result of cost saving actions. As a percentage of net sales, total SG&A increased by 70 basis points to 25.3%, primarily attributable to reduced operating leverage.

Net Interest Expense

• Net interest expense increased $3.0 million to $72.2 million, primarily due to additional interest expense from other finance obligations and higher average debt balances.

Income Tax Expense (Benefit)

• Income tax was $(33.6) million, compared to $37.1 million in the prior year period. The decrease in income tax expense was primarily driven by losses before income taxes incurred by certain subsidiaries in the current year period, as well as lower consolidated income before income taxes.

• Net income was $60.4 million, or $0.56 earnings per diluted share, compared to net income of $122.4 million, or $1.10 earnings per diluted share, in the prior year period.

Non-GAAP Financial Measures

The financial measures entitled Adjusted EBITDA, LTM Adjusted EBITDA, Adjusted EBITDA margin, Adjusted net income, Adjusted net income as a percent of net sales, basic Adjusted net income per share, diluted Adjusted net income per share, Adjusted SG&A, Adjusted SG&A as a percent of net sales, Adjusted effective tax rate, and Free cash flow are not financial measures recognized under GAAP and are therefore non-GAAP financial measures. The Company believes that these non-GAAP financial measures provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and operating results.

Adjusted EBITDA is defined as GAAP net income before depreciation and amortization expense, net interest expense, income tax expense and other non-cash or special items including stock compensation expense, acquisition and related expense, technology implementation expense, debt issuance and refinancing costs, severance and gain on sale of assets and other one-time costs partially offset by the tax effect of those adjustments to net income. LTM Adjusted EBITDA is defined as Adjusted EBITDA for the last twelve consecutive months. Adjusted EBITDA margin is defined as Adjusted EBITDA divided by net sales. Adjusted net income is defined as GAAP net income before non-cash or special items including stock compensation expense, acquisition and related expense, technology implementation expense, debt issuance and refinancing cost, amortization expense, severance, gain or loss on sale of assets and other one-time costs, partially offset by the tax effect of those adjustments to net income and non-recurring discrete income tax items. Adjusted net income as a percent of net sales is defined as Adjusted net income divided by net sales. Basic Adjusted net income per share is defined as Adjusted net income divided by weighted average basic common shares outstanding while diluted Adjusted net income per share is defined as Adjusted net income divided by weighted average diluted common shares outstanding. Adjusted income tax expense is defined as GAAP income tax expense before non-cash or special items including IRS settlement agreements. Adjusted effective tax rate is defined as GAAP income tax expense before non-cash or special items including IRS settlement agreements divided by GAAP income before income taxes. Adjusted SG&A is defined as GAAP SG&A expense before non-cash or special items including stock compensation expense, acquisition and related expense, technology implementation expense, debt issuance and refinancing cost, severance and gain on sale of assets and other one-time costs. Adjusted SG&A as a percent of sales is defined as Adjusted SG&A divided by net sales. Free cash flow is defined as GAAP net cash from operating activities less capital expenditures, net of proceeds from the sale of property, plant and equipment. Note that amounts for prior periods have been updated in this report to present information consistently for all periods presented. The reconciling adjustments are described in the tables below.

Company management uses Adjusted EBITDA, Adjusted EBITDA margin, Adjusted net income, Adjusted net income as a percent of net sales, basic Adjusted net income per share and diluted Adjusted net income per share as supplemental measures in its evaluation of the Company’s business, including for trend analysis, purposes of determining management incentive compensation and budgeting and planning purposes. Company management believes that these measures provide a meaningful measure of the Company’s performance and a better baseline for comparing financial performance across periods because these measures eliminate the effects of period to period changes, in the case of Adjusted EBITDA and Adjusted EBITDA margin, in taxes, costs associated with capital investments, net interest expense, stock compensation expense, and other non-cash and non-recurring items and, in the case of Adjusted net income, Adjusted net income as a percent of sales, and Adjusted net income per diluted share, in certain non-recurring items. Company management also uses free cash flow as a supplemental measure in its evaluation of the Company’s business, including for purposes of its internal liquidity assessments. Company management believes that free cash flow provides a meaningful evaluation of the Company’s liquidity.

The Company believes that these non-GAAP financial measures provide additional tools for investors to use in evaluating ongoing operating results, cash flows and trends and in comparing the Company’s financial measures with other companies in the Company’s industry, which may present similar non-GAAP financial measures to investors. However, the Company’s calculations of these financial measures are not necessarily comparable to similarly titled measures reported by other companies. Company management does not consider these financial measures in isolation or as alternatives to financial measures determined in accordance with GAAP. Furthermore, items that are excluded and other adjustments and assumptions that are made in calculating these non-GAAP financial measures are significant components in understanding and assessing the Company’s financial performance. These non-GAAP financial measures should be evaluated in conjunction with, and are not a substitute for, the Company’s GAAP financial measures. Further, because these non-GAAP financial measures are not determined in accordance with GAAP and are thus susceptible to varying calculations, the non-GAAP financial measures, as presented, may not be comparable to other similarly titled measures of other companies. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the tables below.

The Company’s Adjusted EBITDA outlook, free cash flow and full-year forecast for its effective tax rate on operations exclude the impact of certain income and expense items that management believes are not part of underlying operations. These items may include, but are not limited to, loss on early extinguishment of debt, restructuring charges, certain tax items, and charges associated with non-recurring costs such as professional and legal fees associated with our acquisitions and enterprise resource planning (ERP) program. The Company’s management cannot estimate on a forward-looking basis without unreasonable effort the impact these income and expense items will have on its reported net income, operating cash flow and its reported effective tax rate because these items, which could be significant, are difficult to predict and may be highly variable. As a result, the Company does not provide a reconciliation to the most comparable GAAP financial measure for its Adjusted EBITDA or free cash flow outlook or its effective tax rate on operations forecast. Please see the Forward-Looking Statements section of this release for a discussion of certain risks relevant to the Company’s outlook.
