CLICK TO EDIT TITLE DISCLAIMER 2 Forward-Looking Statements This document contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements in this document may include, without limitation, statements regarding sales growth, price changes, earnings performance, strategic direction and the demand for our products. Forward-looking statements are typically identified by words or phrases such as "may," "might," "predict," "future," "seek to," "assume," "goal," "objective," "continue," "will," "could," "should," "would," "anticipate," "estimate," "expect," "project," "intend," "plan," "believe," "target," "prospects," "guidance," "possible," "predict," "propose," "potential" and "forecast," or the negative of such terms and other words, terms and phrases of similar meaning. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties, many of which are outside BMC Stock Holdings, Inc.’s (“BMC” or the “Company”) control. BMC cautions readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward- looking statement; therefore, investors and shareholders should not place undue reliance on such statement. Such forward-looking statements include, but are not limited to, statements about the benefits of the recently completed merger (the “Merger”) of Stock Building Supply Holdings, Inc. (“SBS” or “Legacy SBS”) with Building Materials Holding Corporation (“Legacy BMC”), including future financial and operating results, plans, objectives, expectations and intentions, and other statements that are not historical facts. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this communication. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements include risks and uncertainties relating to: the risk that the Legacy SBS and Legacy BMC businesses will not be integrated successfully or that such integration will take longer, be more difficult, time- consuming or costly to accomplish than expected; the risk that the cost savings and any other synergies from the Merger may not be fully realized or may take longer to realize than expected; disruption from the Merger may make it more difficult to maintain relationships with customers, employees or suppliers; the diversion of management time on Merger-related issues; general worldwide economic conditions and related uncertainties; changes in the markets for BMC's business segments; unanticipated downturns in business relationships with customers; competitive pressures on the Company's sales and pricing; increases in the cost of material, energy and other production costs, or unexpected costs that cannot be recouped in product pricing; the introduction of competing technologies; unexpected technical or marketing difficulties; unexpected claims, charges, litigation or dispute resolutions; the effect of changes in governmental regulations; and other factors discussed or referred to in the "Risk Factors" section of BMC’s most recent Annual Report on Form 10-K filed on March 1, 2017. All such factors are difficult to predict and are beyond BMC's control. All forward-looking statements attributable to BMC or persons acting on BMC's behalf are expressly qualified in their entirety by the foregoing cautionary statements. All such statements speak only as of the date made, and BMC undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Basis of Presentation The Merger was accounted for as a “reverse acquisition” under the acquisition method of accounting, with Legacy SBS treated as the legal acquirer and Legacy BMC treated as the acquirer for accounting purposes. As such, the Company has accounted for the Merger by using Legacy BMC historical information and accounting policies and adding the assets and liabilities of Legacy SBS as of the completion date of the Merger at their estimated fair values. As a result, current year results reported pursuant to U.S. generally accepted accounting principles (“GAAP”) are not comparable to prior periods.

CLICK TO EDIT TITLE NON-GAAP (ADJUSTED) FINANCIAL MEASURES 3 Adjusted net sales, Adjusted gross profit, Adjusted EBITDA and Adjusted net income are intended as supplemental measures of the Company’s performance that are not required by, or presented in accordance with, GAAP. The Company believes that Adjusted net sales, Adjusted gross profit, Adjusted EBITDA and Adjusted net income provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and operating results. • Adjusted net sales is defined as BMC net sales plus pre-Merger SBS net sales. • Adjusted gross profit is defined as BMC gross profit plus pre-Merger SBS gross profit and inventory step-up charges. • Adjusted EBITDA is defined as BMC net income (loss) plus pre-Merger SBS (loss) income from continuing operations, interest expense, income tax expense (benefit), depreciation and amortization, Merger and integration costs, restructuring expense, inventory step-up charges, non-cash stock compensation expense, loss on debt extinguishment, headquarters relocation expense, insurance deductible reserve adjustment and fire casualty loss, loss on portfolio transfer, acquisition costs and other items and impairment of assets. • Adjusted EBITDA margin is defined as Adjusted EBITDA divided by net sales or Adjusted net sales. • Adjusted net income is defined as BMC net (loss) income plus pre-Merger SBS (loss) income from continuing operations, impairment of assets, Merger and integration costs, inventory step-up charges, non-cash stock compensation expense, loss on debt extinguishment, headquarters relocation expense, loss portfolio transfer, insurance deductible reserve adjustment, fire casualty loss, tax benefit from NOL adjustments, recognition of previously unrecognized tax benefits and other items, and after tax effecting those items. Company management uses Adjusted net sales, Adjusted gross profit, Adjusted EBITDA and Adjusted net income for trend analyses, for purposes of determining management incentive compensation and for budgeting and planning purposes. Adjusted net sales, Adjusted gross profit and Adjusted EBITDA are used in monthly financial reports prepared for management and the board of directors. The Company believes that the use of Adjusted net sales, Adjusted gross profit, Adjusted EBITDA and Adjusted net income provide additional tools for investors to use in evaluating ongoing operating results and trends and in comparing the Company’s financial measures with other distribution and retail companies, which may present similar non-GAAP financial measures to investors. However, the Company’s calculation of Adjusted net sales, Adjusted gross profit, Adjusted EBITDA and Adjusted net income are not necessarily comparable to similarly titled measures reported by other companies. Company management does not consider Adjusted net sales, Adjusted gross profit, Adjusted EBITDA and Adjusted net income in isolation or as alternatives to financial measures determined in accordance with GAAP. The principal limitation of Adjusted EBITDA and Adjusted net income is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. Some of these limitations are: (i) Adjusted EBITDA and Adjusted net income do not reflect changes in, or cash requirements for, working capital needs; (ii) Adjusted EBITDA does not reflect interest expense, or the requirements necessary to service interest or principal payments on debt; (iii) Adjusted EBITDA does not reflect income tax expenses or the cash requirements to pay taxes; (iv) Adjusted net income and Adjusted EBITDA do not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments; (v) although depreciation and amortization charges are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future and Adjusted EBITDA and Adjusted net income do not reflect any cash requirements for such replacements and (vi) Adjusted net income and Adjusted EBITDA do not consider the potentially dilutive impact of issuing non-cash stock-based compensation. In order to compensate for these limitations, management presents Adjusted net sales, Adjusted gross profit, Adjusted EBITDA and Adjusted net income in conjunction with GAAP results. Readers should review the reconciliations of net sales to Adjusted net sales, gross profit to Adjusted gross profit, net income (loss) to Adjusted EBITDA and Adjusted net income, included in the Appendix, and should not rely on any single financial measure to evaluate the Company’s business.
