Dave Flitman, CEO of Builders FirstSource, commented, “I couldn’t be more proud of our team’s effort and hard work that have resulted in record third quarter and first nine months earnings for Builders FirstSource. We delivered above market core organic growth of 16.1%, along with record gross profit, adjusted EBITDA, adjusted EBITDA margin of 17.7% and free cash flow of $1.1 billion. Our team is executing at a very high level as we continue to outperform the market, especially given the strong demand environment coupled with unprecedented supply chain challenges that have continued to affect the homebuilding industry.”

Mr. Flitman continued, “We remain focused on executing our strategy of investing both organically and through M&A to continue to enhance our portfolio of value-added offerings and faster-growth categories. We are excited to welcome the California TrusFrame team to Builders FirstSource, adding substantial and profitable scale to our value- added products business on the West Coast. In addition, the BMC integration continues to progress exceptionally well, and our realization of cost synergies remains ahead of schedule. Looking to the remainder of the year, we continue to expect both strong demand in single-family housing and solid execution of our strategy to drive above market growth, all of which are reflected in our upwardly revised 2021 outlook.”

Peter Jackson, CFO of Builders FirstSource, commented, “During the third quarter, we used a portion of our significant free cash flow to deploy capital in the repurchase of $578 million of stock, and $816 million in acquisitions. Looking ahead, we remain focused on consistently executing our balanced capital allocation strategy with the goal of meeting our commitment to deliver long-term shareholder value.”

Builders FirstSource Financial Performance Highlights—Third Quarter 2021 Compared to Combined Non-GAAP Pro Forma Third Quarter 2020

Pro Forma Net Sales

• Net sales for the period were $5.5 billion, a 62.7% increase compared to the combined pro forma prior year period. Core organic sales, which excludes acquisitions, commodity price fluctuations and differences in the number of selling days between periods, increased by 16.1%, while commodity price inflation contributed 38.6% to net sales.

2

Builders FirstSource Reports Third Quarter 2021 Results (continued)

• Value-added core organic sales grew by an estimated 31.2%, led by 44.6% growth in our Manufactured Products category. Robust demand nationally was somewhat hindered by material availability constraints.

• Demand for single family housing continues to drive top-line growth. For the quarter, our core organic customer growth increased 27.5% for Single Family, declined 16.4% for R&R/Other and declined 2.0% for Multi Family. R&R was down as increased commodity costs constrained R&R projects.

• Acquisitions completed during the prior three quarters, excluding the BMC merger, contributed net sales growth of 8.0%.

Gross Profit

• Gross profit was $1.7 billion, an increase of $868.3 million or 102.9% compared with the combined pro forma prior year period. Our gross margin increased 620 basis points to 31.1%, primarily driven by disciplined pricing in a volatile, supply-constrained marketplace, as well as effective and timely sourcing.

Selling, General and Administrative Expenses

• SG&A was $875.0 million, an increase of approximately $234.8 million, or 36.7%, compared to the combined pro forma prior year period, driven primarily by expense related to the BMC merger and other acquisitions including amortization expense of acquired intangibles and one-time charges. Variable compensation was also higher due to the increase in profitability and core organic growth. As a percentage of net sales, total SG&A decreased by 300 basis points to 15.9% due to the impact of higher net sales and continued expense control.

Interest Expense

• Interest expense increased by $2.4 million to $36.0 million compared to the same combined pro forma prior year period. The year-over-year increase is primarily due to the $1.0 billion senior unsecured Notes due 2032 issued in the third quarter, offset by the payoff of the senior unsecured Notes due 2023.

Income Tax Expense

• Driven by higher profitability, income tax expense was $188.3 million, compared to $39.6 million in the combined pro forma prior year period. The effective tax rate in the third quarter was 23.5%, up 30 basis points versus the prior year period.

Net Income

• Net income was $613.1 million, or $2.98 earnings per diluted share, compared to combined pro forma net income of $130.8 million, or $0.63 earnings per diluted share, in the same period a year ago. Adjusted net income was $696.7 million, or $3.39 adjusted earnings per diluted share, compared to combined pro forma adjusted net income of $154.4 million, or $0.74 adjusted earnings per diluted share, in the prior year period. The 351.2% increase in adjusted net income was primarily driven by the increase in net sales and gross margin described above partially offset by higher tax expense and higher SG&A expense. Adjusted earnings per diluted share excludes amortization and one-time expenses related to merger and acquisition activity.

Adjusted EBITDA

• Adjusted EBITDA increased 244.4% to $975.9 million, driven by solid demand across our key customer end-markets, commodity inflation and cost leverage.

• Adjusted EBITDA margin improved to a record 17.7%, which increased 930 basis points compared to the year-over-year pro forma period.

• Net sales for the period were $15.3 billion, a 69.2% increase compared to the pro forma year-over- year period. Core organic sales, which excludes acquisitions, commodity price fluctuations and differences in the number of selling days between periods, increased by 24.4% while commodity price inflation contributed 40.5% to net sales.

• Value-added core organic sales grew by an estimated 30.3%, led by 48.4% growth in our Manufactured Products category. Robust demand nationally was somewhat hindered by material availability constraints.

• Demand for single family housing continues to drive core organic growth. For the year-over-year period, our core organic growth increased 33.7% for Single Family and increased 0.9% for R&R/Other. There was no change in Multi Family.

• Acquisitions completed during the prior four quarters, excluding the BMC merger, contributed net sales growth of 4.9%.

Gross Profit

• Gross profit was $4.4 billion, an increase of $2.0 billion or 88.3% compared with the combined pro forma prior year period. Our gross margin increased 290 basis points to 28.6%, primarily driven by disciplined pricing in a volatile, supply-constrained marketplace.

Selling, General and Administrative Expenses

• SG&A was $2.6 billion, an increase of approximately $773.2 million or 42.3%, compared to the combined pro forma prior year period, driven primarily by expenses related to the BMC merger and other acquisitions, including amortization expense of acquired intangibles and one-time charges. Variable compensation was also higher due to the increase in profitability and core organic growth. As a percentage of net sales, total SG&A decreased by 320 basis points to 17.0% due to the effect of higher net sales and continued expense control.

Interest Expense

• Interest expense decreased by $27.9 million to $95.6 million compared to the same combined pro forma prior year period. The year-over-year decrease includes higher one-time charges of $28.0 million related to debt financing transactions during the first nine months of 2020, compared to $4.6 million in the first nine months of 2021.

Income Tax Expense

• Driven by higher profitability, income tax expense was $387.1 million, compared to $84.0 million in the combined pro forma prior year period. The effective tax rate was 23.2%, slightly lower than the estimated annual effective tax rate driven primarily by the periodic impact of stock-based compensation adjustments during the nine months ended September 2021.

Net Income

• Net income was $1.3 billion, or $6.18 earnings per diluted share, compared to combined pro forma of $284.2 million, or $1.38 earnings per diluted share, in the same period a year ago. Adjusted net income was $1.6 billion, or $7.55 adjusted earnings per diluted share, compared to a combined pro forma of $351.7 million, or $1.69 adjusted earnings per diluted share, in the prior year period. The 345.6% increase in adjusted net income was primarily driven by the increase in net sales and gross margin. Adjusted earnings per diluted share excludes amortization and one-time expenses related to merger and acquisition activity, as well as losses recognized on the refinancing and extinguishment of debt.

Builders FirstSource Reports Third Quarter 2021 Results (continued)

• Adjusted EBITDA margin improved to 14.9%, which increased 720 basis points compared to the year-over-year pro forma period.

Builders FirstSource Capital Structure, Leverage, and Liquidity Information

• For the first nine months of the year, cash provided by operating activities was $903.2 million; and cash used in investing activities was $970.4 million, including capital expenditures of $148.5 million, net of proceeds. The Company’s free cash was an inflow of $754.8 million, primarily driven by the impact of commodity inflation and core organic growth.

• Liquidity as of September 30, 2021 was $1.5 billion, consisting of over $1.3 billion in net borrowing availability under the revolving credit facility and $225 million cash on hand.

• As of September 30, 2021, Adjusted EBITDA, on a combined pro forma trailing twelve-month basis, was $2.6 billion and net debt was $2.2 billion, resulting in a decrease of our net leverage ratio from 1.6x to 0.8x.

• In the third quarter, BFS repurchased approximately 10,958,400 shares of its common stock at an average price of $52.74, for a total cost of approximately $578 million.

In October, the Company repurchased an additional 4.5 million shares at an average price of $55.99 leaving $172 million in our current authorization.

BMC Merger Integration

Operating in most of the nation’s largest and fastest growing regions, the combined company is exceptionally positioned for long-term value creation. Since closing the merger with BMC on January 1, 2021, Builders FirstSource has made substantial progress in integrating the two companies while delivering solid execution.

The Company’s increased scale, a strong balance sheet bolstered by robust cash generation, and anticipated annual run-rate synergies of $140 million to $160 million by the end of 2022 are expected to provide greater resources to invest in growth, innovation and ongoing value creation for all stakeholders. The Company delivered $36 million in cost synergies in the third quarter and $74 million for the first nine months of 2021. In addition, the Company now expects 2021 cost synergies to be in the range of $90 million to $110 million.

M&A Update

On July 26, 2021, the Company completed the sale of its standalone Eastern U.S. gypsum distribution operations to L&W Supply for total cash proceeds of $76.2 million. The gypsum business generated sales of approximately $160 million in 2020.

On September 1, 2021, the Company acquired California TrusFrame, LLC, (CTF) who was previously the largest independent producer of value-added building products in California, for $193.4 million. CTF reported trailing twelve months’ sales of approximately $143.2 million as of July 31, 2021.

On September 9, 2021, the Company acquired the Apollo software assets from construction technology startup Katerra for approximately $4.5 million. The Apollo platform provides design collaboration and workflow, construction budgeting and scheduling, and field task assignment with mobile functionality.

2021 Outlook

For 2021, the Company expects significant improvement in its financial performance compared to 2020, including the following:

• Net sales to grow to a range of $19.3 billion to $19.8 billion or approximately 51% to 55% over 2020 combined pro forma net sales of $12.8 billion.

• Adjusted EBITDA to be in a range of $2.85 billion to $2.95 billion or approximately 166% to 176% over 2020 combined pro forma Adjusted EBITDA of $1.07 billion.

• Expected BMC merger integration realized cost savings of $90 million to $110 million.

• Free cash flow in the range of $1.8 billion to $2.0 billion.

The 2021 outlook is based on several assumptions, including the following:

• Single family starts percentage growth across our geographies in the mid teens; multi-family starts percentage increase in the high single digits; and R&R growth in the low single digits.

• Commodity price appreciation of 25% to 29% compared to the prior year.

• Recently completed acquisitions projected to add net sales growth of 5% to 6%.

• Two fewer selling days in 2021 versus 2020 or approximately 1%.

• Depreciation and amortization expenses in the range of $555 million to $565 million, including approximately $320 million of amortization related to intangible assets acquired in the BMC merger. Total depreciation projected to be $190 million and total amortization of $370 million for the full year 2021.

• Total capital expenditures spend in the range of $200 million to $220 million.

• Interest expense in the range of $130 million to $140 million.

• An effective tax rate between 23.0% to 25.0%.

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

Non-GAAP Financial Measures

The financial measures entitled Adjusted EBITDA, Adjusted EBITDA margin, Adjusted net income, diluted Adjusted net income per share 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, interest expense, net, income tax expense and other non-cash or special items including stock compensation expense, acquisition and integration expense, debt issuance and refinancing costs, gains (loss) on sale and asset impairments and other items. 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 integration expense and debt issuance and refinancing cost offset by the tax effect of those adjustments to net income. Adjusted net income per diluted share is defined as Adjusted net income divided by weighted average diluted common shares outstanding. 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 and Adjusted net income 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, interest expense, stock compensation expense, and other non-cash and non-recurring items and, in the case of Adjusted net income, 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 calculation 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.

9

Builders FirstSource Reports Third Quarter 2021 Results (continued)

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 professional and legal fees associated with acquisitions. 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.

Pro Forma Combined Financial Data

For avoidance of doubt, the Pro Forma Combined Unaudited and Adjusted Information also was not intended to be, and was not, prepared on a basis consistent with the unaudited pro forma condensed combined financial information included in Builders FirstSource’s Pre-effective amendment to an S-4 filing dated November 17, 2020 with the U.S. Securities and Exchange Commission (the “Pro Forma S-4 Filing”), which provides the pro forma financial information prepared in accordance with Article 11 of SEC Regulation S-X. For instance, the Supplemental Unaudited Combined Financial Information does not give effect to the BMC merger under the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 805, Business Combinations (“ASC Topic 805”), with Builders FirstSource treated as the legal and accounting acquirer, and was not prepared to reflect the merger as if it occurred on the first day of any of the fiscal periods presented. The Pro Forma Combined Unaudited and Adjusted Information has not been adjusted to give effect to pro forma events that are (1) directly attributable to the merger, (2) factually supportable, or (3) expected to have a continuing impact on the combined results of Builders FirstSource and BMC. Consequently, the Pro Forma Combined Unaudited and Adjusted Information is intentionally different from, but does not supersede, the pro forma financial information set forth in the Pro Forma S-4 Filing or the pro forma financial information set forth in the Company’s most recent quarterly report on Form 10-Q.

In addition, the Pro Forma Combined Unaudited and Adjusted Information does not purport to indicate the results that actually would have been obtained had the companies been operated together during the periods presented, or which may be realized in the future. The Pro Forma Combined Unaudited and Adjusted Information have no impact on Builders FirstSource’s or BMC’s previously reported consolidated balance sheets or statements of operations, cash flows or equity.
