On February 2, 2016, the registrant issued a press release announcing certain preliminary financial results for the quarter ended December 31, 2015. The text of the press release is include as Exhibit 99.1 to this Form 8-K.

All of the information furnished in Items 2.02 and 9.01 of this report and the accompanying appendix and Exhibit 99.1 shall not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, and shall not be incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”).

Statements in this report which are not purely historical facts or which necessarily depend upon future events, including statements about expected market share gains, future conditions in the housing or credit markets, forecasted financial performance, forecasted costs savings, or other statements about anticipations, beliefs, expectations, hopes, intentions or strategies for the future, may be forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Readers are cautioned not to place undue reliance on forward-looking statements. All forward-looking statements are based upon information available to Builders FirstSource, Inc. on the date this report 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. Any forward-looking statements involve risks and uncertainties that could cause actual events or results to differ materially from the events or results described in the forward-looking statements, including risks or uncertainties related to the Company’s growth strategies, including market share gains, potential acquisitions, potential cost savings or the Company’s revenues and operating results being highly dependent on, among other things, the homebuilding industry, lumber prices, credit markets and the economy. Builders FirstSource, Inc. 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, Inc.’s most recent filing on Form 10-K with the Securities and Exchange Commission. Consequently, all forward-looking statements in this report are qualified by the factors, risks and uncertainties contained therein.

We occasionally utilize financial measures and terms not calculated in accordance with accounting principles generally accepted in the United States (“GAAP”) in order to provide investors with an alternative method for assessing our operating results in a manner that enables investors to more thoroughly evaluate our current performance as compared to past performance. We also believe these non-GAAP measures provide investors with a better baseline for modeling our future earnings expectations. Our management uses these non-GAAP measures for the same purpose. We believe that our investors should have access to the same set of tools that we use in analyzing our results. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. Our calculation of Adjusted EBITDA is not necessarily comparable to similarly titled measures reported by other companies. We have provided a definition below for these non-GAAP financial measures, together with an explanation of why management uses these measures and why management believes that these non-GAAP financial measures are useful to investors.

We define Adjusted EBITDA as GAAP net income (loss) before depreciation and amortization, interest expense, income taxes, gain (loss) on sale of assets, (income) loss from discontinued operations, and other non-cash or special items including asset impairments, facility closure costs, acquisition costs, severance, transaction and integration costs, and stock compensation expense and certain other unusual or infrequent items that are not representative of underlying trends. Our management uses Adjusted EBITDA as a supplemental measure in the evaluation of our business and believes that Adjusted EBITDA provides a meaningful measure of our performance because it eliminates the effects of period to period changes in taxes, costs associated with capital investments, interest expense, stock compensation expense, and other non-cash and non-recurring items. Adjusted EBITDA is not a financial measure calculated in accordance with GAAP. Accordingly, it should not be considered in isolation or as a substitute for net income (loss) or other financial measures prepared in accordance with GAAP. Because Adjusted EBITDA excludes some, but not all, items that affect net income (loss) and may vary among companies, Adjusted EBITDA presented by us may not be comparable to similarly titled measures of other companies. Adjusted EBITDA does not give effect to the cash we must use to service our debt or pay income taxes and thus does not reflect the funds generated from or used in operations or actually available for capital investments.

We are unable to reconcile Adjusted EBITDA to net income as we have not yet completed our financial closing procedures for the year and the quarter ended December 31, 2015.

The pro forma information combines the historical results of Builders FirstSource, Inc. for the three months ended December 31, 2014 with the historical results of ProBuild Holdings, LLC (“ProBuild”) for the three months ended December 31, 2014, giving effect to the ProBuild acquisition and related adjustments.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this Current Report to be signed on its behalf by the undersigned hereunto duly authorized.
