First Quarter 2026 Financial Performance Highlights

All Year-Over-Year Comparisons Unless Otherwise Noted:

Net Sales

Net sales were $3.3 billion, a 10.1% decrease, primarily due to a lower starts environment. The decrease reflects an 8.3% decline in core organic net sales, as well as commodity deflation of 3.3%, partially offset by growth from acquisitions of 1.5%.
Core organic net sales declined 8.3%. Single Family declined 11.1%, Multi-Family declined 1.4%, and Repair and Remodel ("R&R")/Other declined 1.3%. On a weighted basis, Single Family lowered net sales by 7.9%, R&R/Other by 0.3%, and Multi-Family by 0.1%.

Gross Profit

Gross profit was $0.9 billion, a decrease of 16.7%. Gross profit margin percentage decreased 220 basis points to 28.3%, primarily driven by a lower starts environment.

Selling, General and Administrative Expenses

SG&A was $912.5 million, a decrease of $18.4 million, or 2.0%, primarily driven by lower variable compensation due to lower core organic sales, partially offset by additional expenses from operations acquired within the last twelve months. As a percentage of net sales, total SG&A increased by 240 basis points to 27.8%, primarily attributable to reduced operating leverage.

Net Interest Expense

Net interest expense increased $9.5 million to $74.4 million, primarily due to higher average debt balances.

Income Tax Expense (Benefit)

Income tax was $(10.5) million, compared to $23.2 million in the prior year period, primarily driven by a decrease in income before income taxes. The effective tax rate in the first quarter decreased 130 basis points year-over-year to 18.1%, primarily related to an increase in stock-based compensation benefit.

Net Income (Loss)

Net income (loss) was $(47.4) million, or $(0.43) earnings per diluted share, compared to net income of $96.3 million, or $0.84 earnings per diluted share, in the same period a year ago. The decrease in net income was primarily driven by lower gross profit and higher net interest expense, partially offset by lower SG&A and an income tax benefit.
Net income (loss) as a percentage of net sales was (1.4)%, a decrease of 400 basis points from the prior year period, primarily due to lower gross profit margins and higher net interest expense, partially offset by lower SG&A and an income tax benefit.

Adjusted Net Income

Adjusted net income was $30.0 million, a decrease of 82.6%, primarily driven by lower gross profit and higher net interest expense, partially offset by lower SG&A and income tax expenses.

Adjusted Earnings Per Diluted Share

Adjusted earnings per diluted share was $0.27, compared to $1.51 in the same period a year ago. The 82.1% decrease was primarily driven by lower adjusted net income, partially offset by share repurchases.

Adjusted EBITDA

Adjusted EBITDA decreased 42.1% to $213.8 million, primarily driven by lower gross profit.
Adjusted EBITDA margin declined by 360 basis points from the prior year period to 6.5%, primarily due to lower gross profit margins and reduced operating leverage.

Capital Structure, Leverage, and Liquidity Information

For the three months ended March 31, 2026, cash provided by operating activities was $87.5 million, and cash used in investing activities was $57.8 million. The Company's free cash flow was $42.7 million, compared to $45.0 million in the prior year period, largely the result of lower net income as well as lower capital expenditures.
Liquidity as of March 31, 2026, was approximately $1.5 billion, consisting of $1.4 billion in net borrowing availability under the revolving credit facility and $0.1 billion of cash on hand.
As of March 31, 2026, LTM Adjusted EBITDA was $1.4 billion and net debt was $4.6 billion, resulting in a net debt to LTM Adjusted EBITDA ratio of 3.2x, compared to 2.0x in the prior year period.
In the first quarter, the Company repurchased 3.3 million shares of its common stock at an average price of $92.25 per share for $302.9 million, inclusive of applicable fees and taxes.
On April 29, 2026, the Board of Directors authorized the repurchase of up to $500 million of the Company's outstanding shares of common stock, which includes the approximately $200 million remaining under its prior April 2025 authorization.
Since the inception of its buyback program in August 2021, the Company has repurchased 102.6 million shares of its common stock, or 49.7% of its total shares outstanding, at an average price of $81.26 per share for a total cost of $8.3 billion, inclusive of applicable fees and taxes.

For the first quarter, the Company delivered approximately $6 million in productivity savings related to operational excellence and supply chain initiatives.
The Company expects to deliver $50 million to $70 million in productivity savings in 2026.

Readers are cautioned not to place undue reliance on forward-looking statements. In addition, oral statements made by the Company's directors, officers and employees to the investor and analyst communities, media representatives and others, depending upon their nature, may also constitute forward-looking statements. As with the forward-looking statements included in this release, these forward-looking statements are by nature inherently uncertain, and actual results or events may differ materially as a result of many factors. 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. Forward-looking statements involve risks and uncertainties, many of which are beyond the Company's control or may be currently unknown to the Company, that could cause actual events or results to differ materially from the events or results described in the forward-looking statements; such risks or uncertainties include those related to the Company's growth strategies, including acquisitions, organic growth and digital and technology strategies, including the Company's ability to drive growth by incorporating artificial intelligence and machine learning solutions into its platform, or the dependence of the Company's revenues and operating results on, among other things, the homebuilding industry and, to a lesser extent, repair and remodel activity, which in each case is dependent on economic conditions, including inflation, interest rates, home size and affordability, consumer confidence, labor and supply shortages, tariffs and duties, and also lumber and other commodity prices. The Company 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.
