Google Announces Fourth Quarter and Fiscal Year 2011 Results

MOUNTAIN VIEW, Calif. – January 19, 2012 – Google Inc. (NASDAQ: GOOG) today announced financial results for the quarter and the fiscal year ended December 31, 2011.

“Google had a really strong quarter ending a great year. Full year revenue was up 29%, and our quarterly revenue blew past the $10 billion mark for the first time,” said Larry Page, CEO of Google. “I am super excited about the growth of Android, Gmail, and Google+, which now has 90 million users globally—well over double what I announced just three months ago. By building a meaningful relationship with our users through Google+ we will create amazing experiences across our services. I’m very excited about what we can do in 2012—there are tremendous opportunities to help users and grow our business.”

Q4 Financial Summary

Google reported revenues of $10.58 billion for the quarter ended December 31, 2011, an increase of 25% compared to the fourth quarter of 2010. Google reports its revenues, consistent with GAAP, on a gross basis without deducting traffic acquisition costs (TAC). In the fourth quarter of 2011, TAC totaled $2.45 billion, or 24% of advertising revenues.

Google reports operating income, operating margin, net income, and earnings per share (EPS) on a GAAP and non-GAAP basis. The non-GAAP measures, as well as free cash flow, an alternative non-GAAP measure of liquidity, are described below and are reconciled to the corresponding GAAP measures at the end of this release.

• GAAP operating income in the fourth quarter of 2011 was $3.51 billion, or 33% of revenues. This compares to GAAP operating income of $2.98 billion, or 35% of revenues, in the fourth quarter of 2010. Non-GAAP operating income in the fourth quarter of 2011 was $4.04 billion, or 38% of revenues. This compares to non-GAAP operating income of $3.38 billion, or 40% of revenues, in the fourth quarter of 2010.

• GAAP net income in the fourth quarter of 2011 was $2.71 billion, compared to $2.54 billion in the fourth quarter of 2010. Non-GAAP net income in the fourth quarter of 2011 was $3.13 billion, compared to $2.85 billion in the fourth quarter of 2010.

FORWARD-LOOKING STATEMENTS

This press release contains forward-looking statements that involve risks and uncertainties. These statements include statements regarding our continued investments in our core areas of strategic focus, our expected SBC charges, and our plans to make significant capital expenditures. Actual results may differ materially from the results predicted, and reported results should not be considered as an indication of future performance. The potential risks and uncertainties that could cause actual results to differ from the results predicted include, among others, unforeseen changes in our hiring patterns and our need to expend capital to accommodate the growth of the business, as well as those risks and uncertainties included under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2010, and our most recent Quarterly Report on Form 10-Q for the quarter ended September 30, 2011, which is on file with the SEC and is available on our investor relations website at investor.google.com and on the SEC website at www.sec.gov. Additional information will also be set forth in our Annual Report on Form 10-K for the year ended December 31, 2011. All information provided in this release and in the attachments is as of January 19, 2012, and we undertake no duty to update this information unless required by law.

ABOUT NON-GAAP FINANCIAL MEASURES

To supplement our consolidated financial statements, which statements are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measures: non-GAAP operating income, non-GAAP operating margin, non-GAAP net income, non-GAAP EPS, free cash flow, and non-GAAP international revenues. The presentation of this financial information 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. For more information on these non-GAAP financial measures, please see the tables captioned “Reconciliations of non-GAAP results of operations measures to the nearest comparable GAAP measures,” “Reconciliation from net cash provided by operating activities to free cash flow,” and “Reconciliation from GAAP international revenues to non-GAAP international revenues” included at the end of this release.

We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. Our management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain expenses and expenditures that may not be indicative of our “recurring core business operating results,” meaning our operating performance excluding not only non-cash charges, such as SBC, but also discrete cash charges that are infrequent in nature. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to our historical performance and liquidity as well as comparisons to our competitors’ operating results. We believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) they are used by our institutional investors and the analyst community to help them analyze the health of our business.

Non-GAAP operating income and operating margin. We define non-GAAP operating income as operating income plus expenses related to SBC, and, as applicable, one-time events. Non-GAAP operating margin is defined as non-GAAP operating income divided by revenues. Google considers these non-GAAP financial measures to be useful metrics for management and investors because they exclude the effect of SBC and as applicable, one-time events so that Google’s management and investors can compare Google’s recurring core business operating results over multiple periods. Because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under FASB ASC Topic 718, Google’s management believes that providing a non-GAAP financial measure that excludes SBC allows investors to make meaningful comparisons between Google’s recurring core business operating results and those of other companies, as well as providing Google’s management with an important tool for financial and operational decision making and for evaluating Google’s own recurring core business operating results over different periods of time. There are a number of limitations related to the use of non-GAAP operating income versus operating income calculated in accordance with GAAP. First, non-GAAP operating income excludes some costs, namely, SBC, that are recurring. SBC has been and will continue to be for the foreseeable future a significant recurring expense in Google’s business. Second, SBC is an important part of our employees’ compensation and impacts their performance. Third, the components of the costs that we exclude in our calculation of non-GAAP operating income may differ from the components that our peer companies exclude when they report their results of operations. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP operating income and evaluating non-GAAP operating income together with operating income calculated in accordance with GAAP.

Non-GAAP net income and EPS. We define non-GAAP net income as net income plus expenses related to SBC, and, as applicable, one-time events less the related tax effects. The tax effect of SBC is calculated using the tax-deductible portion of SBC and applying the entity-specific, U.S. federal and blended state tax rates. We define non-GAAP EPS as non-GAAP net income divided by the weighted average outstanding shares, on a fully-diluted basis. We consider these non-GAAP financial measures to be a useful metric for management and investors for the same reasons that Google uses non-GAAP operating income and non-GAAP operating margin. However, in order to provide a complete picture of our recurring core business operating results, we exclude from non-GAAP net income and non-GAAP EPS the tax effects associated with SBC. Without excluding these tax effects, investors would only see the gross effect that excluding these expenses had on our operating results. The same limitations described above regarding Google’s use of non-GAAP operating income and non-GAAP operating margin apply to our use of non-GAAP net income and non-GAAP EPS. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP net income and non-GAAP EPS and evaluating non-GAAP net income and non-GAAP EPS together with net income and EPS calculated in accordance with GAAP.

Free cash flow. We define free cash flow as net cash provided by operating activities less capital expenditures. We consider free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after the acquisition of property and equipment, including information technology infrastructure and land and buildings, can be used for strategic opportunities, including investing in our business, making strategic acquisitions, and strengthening the balance sheet. Analysis of free cash flow also facilitates management’s comparisons of our operating results to competitors’ operating results. A limitation of using free cash flow versus the GAAP measure of net cash provided by operating activities as a means for evaluating Google is that free cash flow does not represent the total increase or decrease in the cash balance from operations for the period because it excludes cash used for capital expenditures during the period. Our management compensates for this limitation by providing information about our capital expenditures on the face of the statement of cash flows and under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Quarterly Report on Form 10-Q and Annual Report on Form 10-K. Google has computed free cash flow using the same consistent method from quarter to quarter and year to year.

Non-GAAP international revenues. We define non-GAAP international revenues as international revenues excluding the impact of foreign exchange and hedging. Non-GAAP international revenues are calculated by translating current quarter revenues using prior quarter and prior year exchange rates, as well as excluding any hedging gains realized in the current quarter. We consider non-GAAP international revenues as a useful metric as it facilitates management’s internal comparison to our historical performance.

The accompanying tables have more details on the GAAP financial measures that are most directly comparable to non-GAAP financial measures and the related reconciliations between these financial measures.
