2 Forward-Looking Statements Some of the statements contained in this presentation may constitute forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, projections, plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. In some cases, you can identify forward-looking statements by the use of forward-looking terminology such as ''may,'' ''will,'' ''should,'' ''expects,'' ''intends,'' ''plans,'' ''anticipates,'' ''believes,'' ''estimates,'' ''predicts,'' or ''potential'' or the negative of these words and phrases or similar words or phrases that are predictions of or indicate future events or trends and which do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions. The forward-looking statements contained in this presentation reflect our current views about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances that may cause actual results to differ significantly from those expressed or contemplated in any forward-looking statement. While forward-looking statements reflect our good faith projections, assumptions and expectations, they are not guarantees of future results. Furthermore, we disclaim any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events or other changes, except as required by applicable law. Factors that could cause our results to differ materially include, but are not limited to: (1) general economic conditions and multifamily and commercial real estate market conditions, (2) regulatory and/or legislative changes to Freddie Mac, Fannie Mae or HUD, (3) our ability to retain and attract loan originators and other professionals, (4) risks related to our recently completed acquisitions, including our ability to integrate and achieve the expected benefits of such acquisitions, and (5) changes in federal government fiscal and monetary policies, including any constraints or cuts in federal funds allocated to HUD for loan originations. For a further discussion of these and other factors that could cause future results to differ materially from those expressed or contemplated in any forward-looking statements, see the section titled ''Risk Factors" in our most recent Annual Report on Form 10-K, as it may be updated or supplemented by our subsequent Quarterly Reports on Form 10-Q and other SEC filings. Such filings are available publicly on our Investor Relations web page at www.walkerdunlop.com. Non-GAAP Financial Measures To supplement our financial statements presented in accordance with United States generally accepted accounting principles (“GAAP”), the Company uses adjusted EBITDA and estimated Alliant adjusted EBITDA, each a non- GAAP financial measure. The presentation of adjusted EBITDA is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. When analyzing our operating performance, readers should use adjusted EBITDA in addition to, and not as an alternative for, net income. Adjusted EBITDA represents net income before income taxes, interest expense on our term loan facility and Alliant’s note payable, and amortization and depreciation, adjusted for provision (benefit) for credit losses net of write-offs, stock-based incentive compensation charges, the fair value of expected net cash flows from servicing, net, and the gain associated with the revaluation of our previously held equity-method investment in connection with our acquisition of GeoPhy. In addition, adjusted EBITDA further excludes the impact of the acquisition of CWCapital and deal-related expenses, integration and restructuring costs, severance and lease restructuring charges related to our fourth quarter 2013 expense reduction efforts, early extinguishment of our term loan facility, and revenues from the termination fee related to the transfer of servicing for a portion of the small loan portfolio that are not considered part of our ongoing operations. Estimated adjusted EBITDA for Alliant presented in this presentation represents estimated Alliant net income before income taxes, interest expense on estimated incremental debt associated with our acquisition of Alliant, including an estimated increase to our corporate debt and Alliant’s existing debt assumed by us upon closing of the acquisition, and amortization and depreciation, adjusted for provision (benefit) for credit losses net of write-offs, stock-based incentive compensation charges, and non-cash revenues such as the fair value of expected net cash flows from servicing, net. Because not all companies use identical calculations, our presentation of adjusted EBITDA may not be comparable to similarly titled measures of other companies. Furthermore, adjusted EBITDA is not intended to be a measure of free cash flow for our management's discretionary use, as it does not reflect certain cash requirements such as tax and debt service payments. The amounts shown for adjusted EBITDA may also differ from the amounts calculated under similarly titled definitions in our debt instruments, which are further adjusted to reflect certain other cash and non-cash charges that are used to determine compliance with financial covenants. We use adjusted EBITDA to evaluate the operating performance of our business, for comparison with forecasts and strategic plans, and for benchmarking performance externally against competitors. We believe that this non-GAAP measure, when read in conjunction with our GAAP financials, provides useful information to investors by offering: − the ability to make more meaningful period-to-period comparisons of the Company's on-going operating results; − the ability to better identify trends in the Company's underlying business and perform related trend analyses; and − a better understanding of how management plans and measures the Company's underlying business. We believe that adjusted EBITDA has limitations in that it does not reflect all of the amounts associated with the Company's results of operations as determined in accordance with GAAP and that adjusted EBITDA should only be used to evaluate the Company's results of operations in conjunction with net income. For information on adjusted EBITDA, refer to the appendix of this presentation. Estimated adjusted EBITDA for Alliant presented in this presentation represents estimated Alliant net income before income taxes, interest expense on estimated incremental debt associated with our acquisition of Alliant, including an estimated increase to our corporate debt and Alliant’s existing debt assumed by us upon closing of the acquisition, and amortization and depreciation, adjusted for provision (benefit) for credit losses net of write-offs, stock-based incentive compensation charges, and non-cash revenues such as the fair value of expected net cash flows from servicing, net. For information on Estimated adjusted EBITDA, refer to the appendix of this presentation.
