Net sales were $3.9 billion, a 6.9% decrease, driven by lower core organic net sales and commodity deflation, partially offset by growth from acquisitions.

Adjusted EBITDA decreased 30.8% to $433.7 million, primarily driven by lower gross profit.
Adjusted EBITDA margin declined by 380 basis points to 11.0%, attributable to lower gross margin and reduced operating leverage.

The Company's free cash flow was $464.9 million, a decrease of 26.8%, compared to $634.7 million in the prior year period. The decrease was primarily driven by lower net income.

Peter Jackson, CEO of Builders FirstSource, commented: "Our third quarter results reflect the strength of our strategy and disciplined execution in a weak housing market. Over the past several years, we have transformed into a stronger organization powered by our leading network of value-added solutions, a relentless focus on operational excellence, and capital deployment. These pillars, combined with our scale and a team dedicated to exceptional customer service, reinforce our industry leadership position and our track record of success.

Pete Beckmann, CFO of Builders FirstSource, added, "We continue to execute our strategy in a down market, responding to near-term challenges by carefully managing costs while preserving our ability to invest for the future. Our financial agility, supported by a healthy balance sheet and strong free cash flow through the cycle, enables us to deploy capital prudently to fuel organic growth, pursue strategic M&A, and return capital to shareholders. These investments are bolstering our competitive position as we invest for the future."

Third Quarter 2025 Financial Performance Highlights

All Year-Over-Year Comparisons Unless Otherwise Noted:

Net Sales

Net sales were $3.9 billion, a 6.9% decrease, driven by a 10.6% decline in core organic net sales and commodity deflation of 1.1%, partially offset by growth from acquisitions of 4.8%.
Core organic net sales declined 10.6%. Multi-Family declined 20.2%, Single Family declined 12.1%, and Repair and Remodel ("R&R")/Other declined 1.2%. On a weighted basis, Single Family lowered net sales by 8.2%, Multi-Family by 2.2%, and R&R/Other by 0.2%.

Gross Profit

Gross profit was $1.2 billion, a decrease of 13.5%. Gross profit margin percentage decreased 240 basis points to 30.4%, primarily driven by a below-normal starts environment.

Selling, General and Administrative Expenses

SG&A was $970.7 million, an increase of $12.4 million, or 1.3%, primarily driven by additional expenses from operations acquired within the last twelve months and our ongoing enterprise resource planning system implementation, partially offset by lower variable compensation due to lower core organic sales and the absence of prior-year asset write-offs. As a percentage of net sales, total SG&A increased by 200 basis points to 24.6%, primarily attributable to reduced operating leverage.

Net Interest Expense

Net interest expense increased $15.0 million to $69.3 million, primarily due to higher average debt balances.

Income Tax Expense

Income tax expense was $37.1 million, compared to $89.0 million in the prior year period, primarily driven by a decrease in income before income tax. The effective tax rate in the third quarter decreased 50 basis points year-over-year to 23.3%, primarily related to decreased permanent and other differences.

Net Income

Net income was $122.4 million, or $1.10 earnings per diluted share, compared to net income of $284.8 million, or $2.44 earnings per diluted share, in the same period a year ago. The 57.0% decrease in net income was primarily driven by lower gross profit and higher SG&A and net interest expense, partially offset by lower income tax expenses.
Net income as a percentage of net sales was 3.1%, a decrease of 360 basis points from the prior year period, primarily due to lower gross profit margins and higher SG&A and net interest expense, partially offset by lower income tax expenses.

Adjusted Net Income

Adjusted net income was $208.6 million, a decrease of 42.0%, primarily driven by lower gross profit and higher net interest expense, partially offset by lower income tax expenses.

Adjusted Earnings Per Diluted Share

Adjusted earnings per diluted share was $1.88, compared to $3.07 in the same period a year ago. The 38.8% decrease was primarily driven by lower adjusted net income, partially offset by share repurchases.

Adjusted EBITDA

Adjusted EBITDA decreased 30.8% to $433.7 million, primarily driven by lower gross profit.
Adjusted EBITDA margin declined by 380 basis points from the prior year period to 11.0%, primarily due to lower gross profit margins and reduced operating leverage.

As of September 30, 2025, LTM Adjusted EBITDA was $1.8 billion and net debt was $4.2 billion, resulting in a net debt to LTM Adjusted EBITDA ratio of 2.3x, compared to 1.4x in the prior year period.

Readers are cautioned not to place undue reliance on forward-looking statements. In addition, oral statements made by our directors, officers and employees to the investor and analyst communities, media representatives and others, depending upon their nature, may also constitute forward-looking statements.

All forward-looking statements are based upon information available to Builders FirstSource on the date this release was submitted. Builders FirstSource undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Builders FirstSource may not succeed in addressing these and other risks. Further information regarding factors that could affect our financial and other results can be found in the risk factors section of Builders FirstSource's most recent annual report on Form 10-K filed with the Securities and Exchange Commission (the "SEC") and may also be described from time to time in the other reports Builders FirstSource files with the SEC.

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, 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 acquisition and related expense, technology implementation expense, debt issuance and refinancing cost and amortization expense partially offset by the tax effect of those adjustments to net income. 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 SG&A is defined as GAAP SG&A expense before non-cash or special items including depreciation expense, amortization expense, stock compensation expense, acquisition and related expense, and technology implementation expense. 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.

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.
