Non-GAAP Financial Measures

This press release and its attachments include the following financial measures defined as non-GAAP financial measures by the Securities and Exchange Commission (“SEC”): revenue ex-TAC; adjusted EBITDA; non-GAAP income from operations; non-GAAP net earnings; non-GAAP net earnings per share – diluted; and free cash flow.

Revenue ex-TAC is GAAP revenue less traffic acquisition costs. Adjusted EBITDA, non-GAAP income from operations, non-GAAP net earnings and non-GAAP net earnings per share – diluted, exclude from the most comparable GAAP financial measures certain gains, losses, and expenses that we do not believe are indicative of ongoing results, and exclude stock-based compensation expense. Adjusted EBITDA also excludes taxes, depreciation, amortization of intangible assets, other income, net (which includes interest), earnings in equity interests, and net income attributable to noncontrolling interests. Free cash flow is GAAP net cash provided by operating activities (adjusted to include excess tax benefits from stock-based awards), less acquisition of property and equipment, net and dividends received from equity investees.

These measures may be different than non-GAAP financial measures used by other companies. The presentation of this financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with generally accepted accounting principles (“GAAP”).

Note to Unaudited Condensed Consolidated Financial Statements

This press release and its attachments include the non-GAAP financial measures of revenue excluding traffic acquisition costs (“revenue ex-TAC”); adjusted EBITDA; non-GAAP income from operations; non-GAAP net earnings; non-GAAP net earnings per diluted share; and free cash flow, which are reconciled to revenue; net income attributable to Yahoo! Inc. (in the case of adjusted EBITDA and non-GAAP net earnings); income from operations; net income attributable to Yahoo! Inc. common stockholders per share – diluted; and net cash provided by operating activities, which we believe are the most comparable GAAP measures. We use these non-GAAP financial measures for internal managerial purposes and to facilitate period-to-period comparisons. We describe limitations specific to each non-GAAP financial measure below. Management generally compensates for limitations in the use of non-GAAP financial measures by relying on comparable GAAP financial measures and providing investors with a reconciliation of the non-GAAP financial measure to the most directly comparable GAAP financial measure or measures. Further, management uses non-GAAP financial measures only in addition to and in conjunction with results presented in accordance with GAAP. We believe that these non-GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. These non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, revenue, net income attributable to Yahoo! Inc., income from operations, net income attributable to Yahoo! Inc. common stockholders per share – diluted, and net cash provided by operating activities calculated in accordance with GAAP.

Revenue ex-TAC is a non-GAAP financial measure defined as GAAP revenue less TAC. TAC consists of payments made to third-party entities that have integrated our advertising offerings into their Websites or other offerings (those Websites and other offerings, “Affiliate sites”) and payments made to companies that direct consumer and business traffic to Yahoo’s online properties and services (“Yahoo Properties”). Based on the terms of the Search Agreement with Microsoft, Microsoft retains a revenue share of 12 percent of the net (after TAC) search revenue generated on Yahoo Properties and Affiliate sites in transitioned markets. Yahoo reports the net revenue it receives under the Search Agreement as revenue and no longer presents the associated TAC. Accordingly, for transitioned markets Yahoo reports GAAP revenue associated with the Search Agreement on a net (after TAC) basis rather than a gross basis. For markets that have not yet transitioned, revenue continues to be recorded on a gross basis, and TAC is recorded as a part of operating expenses. We present revenue ex-TAC to provide investors a metric used by the Company for evaluation and decision-making purposes during the Microsoft transition and to provide investors with comparable revenue numbers when comparing periods preceding, during and following the transition period. A limitation of revenue ex-TAC is that it is a measure which we have defined for internal and investor purposes that may be unique to the Company, and therefore it may not enhance the comparability of our results to other companies in our industry who have similar business arrangements but address the impact of TAC differently. Management compensates for these limitations by also relying on the comparable GAAP financial measures of revenue and total operating expenses, which includes TAC in non-transitioned markets.

Adjusted EBITDA is defined as net income attributable to Yahoo! Inc. before taxes, depreciation, amortization of intangible assets, stock-based compensation expense, other income, net (which includes interest), earnings in equity interests, net income attributable to noncontrolling interests and other gains, losses, and expenses that we do not believe are indicative of our ongoing results. Yahoo presents adjusted EBITDA because the exclusion of certain gains, losses, and expenses facilitates comparisons of the operating performance of our Company on a period to period basis. Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation or as a substitute for results reported under GAAP. These limitations include: adjusted EBITDA does not reflect tax payments and such payments reflect a reduction in cash available to us; adjusted EBITDA does not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in our businesses; adjusted EBITDA does not include stock-based compensation expense related to the Company’s workforce; adjusted EBITDA also excludes other income, net (which includes interest), earnings in equity interests, net income attributable to noncontrolling interests and other gains, losses, and expenses that we do not believe are indicative of our ongoing results, and these items may represent a reduction or increase in cash available to us; and adjusted EBITDA is a measure that may be unique to the Company, and therefore it may not enhance the comparability of our results to other companies in our industry. Management compensates for these limitations by also relying on the comparable GAAP financial measure of net income attributable to Yahoo! Inc., which includes taxes, depreciation, amortization, stock-based compensation expense, other income, net (which includes interest), earnings in equity interests, net income attributable to noncontrolling interests and the other gains, losses and expenses that are excluded from adjusted EBITDA.

Non-GAAP income from operations is defined as income from operations excluding certain gains, losses, and expenses that we do not believe are indicative of our ongoing operating results and further adjusted to exclude stock-based compensation expense. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, and the subjective assumptions involved in those determinations, we believe excluding stock-based compensation expense enhances the ability of management and investors to understand the impact of stock-based compensation expense on income from operations. We consider non-GAAP income from operations to be a profitability measure which facilitates the forecasting of our operating results for future periods and allows for the comparison of our results to historical periods. A limitation of non-GAAP income from operations is that it does not include all items that impact our income from operations for the period. Management compensates for this limitation by also relying on the comparable GAAP financial measure of income from operations which includes the gains, losses, and expenses that are excluded from non-GAAP income from operations.

Non-GAAP net earnings is defined as net income attributable to Yahoo! Inc. excluding certain gains, losses, expenses, and their related tax effects that we do not believe are indicative of our ongoing results and further adjusted to exclude stock-based compensation expense and its related tax effects. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, and the subjective assumptions involved in those determinations, we believe excluding stock-based compensation expense enhances the ability of management and investors to understand the impact of stock-based compensation expense on net income and net income per share. We consider non-GAAP net earnings and non-GAAP net earnings per diluted share to be profitability measures which facilitate the forecasting of our results for future periods and allow for the comparison of our results to historical periods. A limitation of non-GAAP net earnings and non-GAAP net earnings per diluted share is that they do not include all items that impact our net income and net income per diluted share for the period. Management compensates for this limitation by also relying on the comparable GAAP financial measures of net income attributable to Yahoo! Inc. and net income attributable to Yahoo! Inc. common stockholders per share – diluted, both of which include the gains, losses, expenses and related tax effects that are excluded from non-GAAP net earnings and non-GAAP net earnings per diluted share.

Free cash flow is a non-GAAP financial measure defined as net cash provided by operating activities (adjusted to include excess tax benefits from stock-based awards), less acquisition of property and equipment, net and dividends received from equity investees. We consider free cash flow to be a liquidity measure which provides useful information to management and investors about the amount of cash generated by the business after the acquisition of property and equipment, which can then be used for strategic opportunities including, among others, investing in the Company’s business, making strategic acquisitions, strengthening the balance sheet, and repurchasing stock. A limitation of free cash flow is that it does not represent the total increase or decrease in the cash balance for the period. Management compensates for this limitation by also relying on the net change in cash and cash equivalents as presented in the Company’s unaudited condensed consolidated statements of cash flows prepared in accordance with GAAP which incorporates all cash movements during the period.
