Disclaimer 1 Non-GAAP Financial Measures Forward-Looking Statements This document contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. 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,” “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. Stock Building Supply Holdings, Inc. (“STOCK” or “STOCK BUILDING SUPPLY”) 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. Such forward-looking statements include, but are not limited to, statements about the benefits of the proposed merger involving Building Materials Holding Corporation (“BMC”) and Stock Building Supply, including future financial and operating results, Stock Building Supply’s or BMC’s plans, objectives, expectations and intentions, the expected timing of completion of the transaction, 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 ability to obtain the requisite BMC and Stock Building Supply shareholder approvals; the risk that Stock Building Supply or BMC may be unable to obtain governmental and regulatory approvals required for the merger, or required governmental and regulatory approvals may delay the merger or result in the imposition of conditions that could cause the parties to abandon the merger; the risk that a condition to closing of the merger may not be satisfied; the timing to consummate the proposed merger; the risk that the businesses will not be integrated successfully; the risk that the cost savings and any other synergies from the transaction may not be fully realized or may take longer to realize than expected; disruption from the transaction making 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; the effect of changes in governmental regulations; and other factors discussed or referred to in the “Risk Factors” section of Stock Building Supply’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 2, 2015, and our subsequent filings with the SEC. These risk factors, as well as other risks associated with the merger, will be more fully discussed in the Registration Statement and the Proxy /Consent Solicitation Statement/Prospectus (as defined below). All such factors are difficult to predict and are beyond Stock Building Supply and BMC’s control. All forward-looking statements attributable to Stock Building Supply or persons acting on Stock Building Supply’s behalf are expressly qualified in their entirety by the foregoing cautionary statements. All such statements speak only as of the date made, and Stock Building Supply and BMC undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Included in this presentation are certain non-GAAP financial measures designed to complement the financial information presented in accordance with generally accepted accounting principles in the United States of America. Our management believes such measures are useful to investors. Because the Company’s calculations of these measures may differ from similar measures used by other companies, you should be careful when comparing the Company’s non-GAAP financial measures to those of other companies. A reconciliation of non-GAAP financial measures to GAAP financial measures is included in an appendix to this presentation. |
