For Immediate Release Builders FirstSource Reports First Quarter 2025 Results May 1, 2025 (Irving, TX) – Builders FirstSource, Inc. (NYSE: BLDR) today reported its results for the first quarter ended March 31, 2025. First Quarter 2025 Highlights All Year-Over-Year Comparisons Unless Otherwise Noted: • Net sales were $3.7 billion, a 6.0% decrease, driven by lower core organic sales, one fewer selling day, and commodity deflation, partially offset by growth from acquisitions. • Gross profit margin decreased 290 basis points to 30.5%, primarily driven by Single- and Multi-Family margin normalization as well as a below-normal starts environment. • Net income was $96.3 million, or diluted EPS of $0.84 compared to diluted EPS of $2.10 in the prior year period. Net income as a percent of net sales decreased by 402 basis points to 2.6%. • Adjusted EBITDA decreased 31.7% to $369.2 million, primarily driven by lower gross profit, partially offset by lower operating expenses after adjustments. • Adjusted EBITDA margin declined by 380 basis points to 10.1%, attributable to lower gross margin and reduced operating leverage. • Cash provided by operating activities was $132.3 million, a decrease of $184.9 million compared to the prior year period. The Company's free cash flow was $45.0 million, a decrease of 80.2%, compared to $227.6 million in the prior year period. The decrease was primarily driven by lower net income. • The Company repurchased 0.1 million shares of common stock at an average price of $131.51 for $12.8 million, inclusive of applicable fees and taxes.

First Quarter 2025 Financial Performance Highlights All Year-Over-Year Comparisons Unless Otherwise Noted: Net Sales • Net sales were $3.7 billion, a 6.0% decrease, driven by an 8.1% decline in core organic sales, a headwind from one fewer selling day of 1.6%, and commodity deflation of 1.0%, partially offset by growth from acquisitions of 4.7%. • Core organic net sales declined 8.1%. Multi-Family declined 32.7% and Single-Family declined 5.9%, while Repair and Remodel (“R&R”)/Other increased 3.6%. On a weighted basis, Multi-Family and Single-Family lowered net sales by 4.6% and 4.2%, respectively, while R&R/Other raised sales by 0.7%. Gross Profit • Gross profit was $1.1 billion, a decrease of 14.2%. Gross profit margin percentage decreased 290 basis points to 30.5%, primarily driven by Single- and Multi-Family margin normalization as well as a below-normal starts environment. Selling, General and Administrative Expenses • SG&A was $930.8 million, an increase of $4.5 million, or 0.5%, 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 lower intangible amortization. As a percentage of net sales, total SG&A increased by 160 basis points to 25.4%, primarily attributable to reduced operating leverage. Interest Expense • Interest expense, net increased $16.6 million to $64.9 million, primarily due to higher average debt balances. Income Tax Expense • Income tax expense was $23.2 million, compared to $66.5 million in the prior year period, primarily driven by a decrease in income before income tax. The effective tax rate in the first quarter decreased 100 basis points year-over-year to 19.4%, primarily related to favorable permanent and other differences, partially offset by a lower stock-based compensation windfall benefit. Net Income • Net income was $96.3 million, or $0.84 earnings per diluted share, compared to net income of $258.8 million, or $2.10 earnings per diluted share, in the same period a year ago. The 62.8% decrease in net income was primarily driven by lower gross profit and higher net interest expense, partially offset by lower income tax expenses. 2 • Net income as a percentage of net sales was 2.6%, a decrease of 402 bps from the prior year period, primarily due to lower gross profit margins and higher net interest expense, partially offset by lower income tax expenses. Adjusted Net Income • Adjusted net income was $172.9 million, a decrease of 47.2%, primarily driven by lower gross profit and higher net interest expense, partially offset by lower operating expenses after adjustments and lower income tax expenses. Adjusted Earnings Per Diluted Share • Adjusted earnings per diluted share was $1.51, compared to $2.65 in the same period a year ago. The 43.0% decrease was primarily driven by lower adjusted net income, partially offset by share repurchases. Adjusted EBITDA • Adjusted EBITDA decreased 31.7% to $369.2 million, primarily driven by lower gross profit, partially offset by lower operating expenses after adjustments. • Adjusted EBITDA margin declined by 380 basis points from the prior year period to 10.1%, primarily due to lower gross profit margins and reduced operating leverage. Capital Structure, Leverage, and Liquidity Information • For the three months ended March 31, 2025, cash provided by operating activities was $132.3 million, and cash used in investing activities was $912.1 million. The Company's free cash flow was $45.0 million, compared to $227.6 million in the prior year period, largely the result of lower net income and an increase in net working capital. • Liquidity as of March 31, 2025, was approximately $1.1 billion, consisting of $944 million in net borrowing availability under the revolving credit facility and $115 million of cash on hand. • As of March 31, 2025, LTM Adjusted EBITDA was $2.2 billion and net debt was $4.4 billion, resulting in the net debt to LTM Adjusted EBITDA ratio of 2.0x, compared to 1.1x in the prior year period. • In the first quarter, the Company repurchased 0.1 million shares of its common stock at an average price of $131.51 per share for $12.8 million, inclusive of applicable fees and taxes. • In April 2025, the Company repurchased 3.3 million shares of its common stock at an average price of $118.27 per share for $390.9 million, inclusive of applicable fees and taxes. • On April 30, 2025, 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 $100 million remaining under its prior $1 billion share repurchase authorization announced in August 2024. • Since the inception of its buyback program in August 2021, 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, inclusive of applicable fees and taxes. Productivity Savings From Operational Excellence 3 • For the first quarter, the Company delivered approximately $17 million in productivity savings related to operational excellence and supply chain initiatives. • The Company expects to deliver $70 million to $90 million in productivity savings in 2025. 2025 Full Year Total Company Outlook For 2025, the Company expects to achieve the financial performance highlighted below. Projected Net Sales and Adjusted EBITDA include the expected impact of price, commodities, and margins for 2025. • Net Sales to be in a range of $16.05 billion to $17.05 billion. • Gross Profit margin to be in a range of 29.0% to 31.0%. • Adjusted EBITDA to be in a range of $1.7 billion to $2.1 billion. • Adjusted EBITDA margin to be in a range of 10.6% to 12.3%. • Free cash flow in the range of $800 million to $1.2 billion, assuming average commodity prices in the range of $400 to $440 per thousand board foot (mbf). 2025 Full Year Assumptions The Company’s anticipated 2025 performance is based on several assumptions for the full year, including the following: • Within the Company’s geographies, Single-Family starts are projected to be down mid-single digits, Multi-Family starts down mid-teens, and R&R is projected to be flat. • Acquisitions completed within the last twelve months are projected to add net sales growth of 5.0% to 5.5%. • Total capital expenditures in the range of $350 million to $425 million. • Interest expense in the range of $260 million to $280 million. • An effective tax rate of 23.0% to 25.0%. • Depreciation and amortization expenses in the range of $550 million to $600 million. • One fewer selling day is projected to decrease net sales by 0.4% in 2025 versus 2024.

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. 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 strategies, 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, consumer confidence, labor and supply shortages, and also lumber and other commodity prices. 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. Consequently, all forward-looking statements in this release are qualified by the factors, risks and uncertainties contained therein. Non-GAAP Financial Measures The financial measures entitled Adjusted EBITDA, LTM Adjusted EBITDA, Adjusted EBITDA margin, Adjusted net income, basic Adjusted net income per share, diluted Adjusted net income per share, 5 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. 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, 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 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. 6 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. # # # Contact: Heather Kos SVP, Investor Relations Builders FirstSource, Inc. investorrelations@bldr.com 7 BUILDERS FIRSTSOURCE, INC.
