Non-GAAP Financial Measures

To supplement its financial information, the Company has presented, and/or may discuss on the conference call, adjusted earnings per diluted share, adjusted net income, adjusted income from operations, adjusted operating EBITDA and margin, adjusted SG&A expenses and free cash flow. All of these items are non-GAAP financial measures, as defined in Regulation G of the Securities Exchange Act of 1934, as amended. The Company reports its financial results in compliance with GAAP but believes that also discussing non-GAAP measures provides investors with (i) financial measures the Company uses in the management of its business and (ii) additional, meaningful comparisons of current results to prior periods’ results by excluding items

that the Company does not believe reflect its fundamental business performance and are not representative or indicative of its results of operations.

In addition, the Company’s projected adjusted operating EBITDA and margin is anticipated to be adjusted to exclude the effects of other events or circumstances that are not representative or indicative of the Company’s results of operations. Such excluded items are not currently determinable, but may be significant, such as asset impairments and one-time items, charges, gains or losses from divestitures or litigation, and other items. Due to the uncertainty of the likelihood, amount and timing of any such items, the Company does not have information available to provide a quantitative reconciliation of such projection to the comparable GAAP measure.

The Company discusses free cash flow and provides a projection of free cash flow because the Company believes that it is indicative of its ability to pay its quarterly dividends, repurchase common stock, fund acquisitions and other investments and, in the absence of refinancings, to repay its debt obligations. The Company believes free cash flow gives investors useful insight into how the Company views its liquidity, but the use of free cash flow as a liquidity measure has material limitations because it excludes certain expenditures that are required or that the Company has committed to, such as declared dividend payments and debt service requirements. The Company defines free cash flow as net cash provided by operating activities, less capital expenditures, plus proceeds from divestitures of businesses and other assets (net of cash divested); this definition may not be comparable to similarly-titled measures reported by other companies.

The quantitative reconciliations of non-GAAP measures to the most comparable GAAP measures are included in the accompanying schedules, with the exception of projected adjusted operating EBITDA and margin. Non-GAAP measures should not be considered a substitute for financial measures presented in accordance with GAAP.
