“We were very pleased with how our business performed in 2009, capping a solid year with a return to double-digit revenue growth in the fourth quarter,” said Paul Sagan, president and CEO of Akamai. “For the year, we grew revenue, improved our cash gross margins, and generated over $400 million of cash from operations in a tough economic environment.

*Use of Non-GAAP Financial Measures

In addition to providing financial measurements based on generally accepted accounting principles in the United States of America (GAAP), Akamai has historically provided additional financial metrics that are not prepared in accordance with GAAP (non-GAAP). Legislative and regulatory changes discourage the use of and emphasis on non-GAAP financial metrics and require companies to explain why non-GAAP financial metrics are relevant to management and investors. We believe that the inclusion of these non-GAAP financial measures in this press release helps investors to gain a meaningful understanding of our past performance and future prospects, consistent with how management measures and forecasts our performance, especially when comparing such results to previous periods or forecasts. Our management uses these non-GAAP measures, in addition to GAAP financial measures, as the basis for measuring our core operating performance and comparing such performance to that of prior periods and to the performance of our competitors. These measures are also used by management in its financial and operational decision-making. There are limitations associated with reliance on these non-GAAP financial metrics because they are specific to our operations and financial performance, which makes comparisons with other companies’ financial results more challenging. By providing both GAAP and non-GAAP financial measures, we believe that investors are able to compare our GAAP results to those of other companies while also gaining a better understanding of our operating performance as evaluated by management.

Akamai defines “Adjusted EBITDA” as net income, before interest, taxes, depreciation and amortization of tangible and intangible assets, stock-based compensation expense, amortization of capitalized stock-based compensation, restructuring charges and benefits, certain gains and losses on investments, foreign exchange gains and losses, loss on early extinguishment of debt, gains on legal settlements, utilization of tax NOLs/credits and release of the deferred tax asset valuation allowance. Akamai considers Adjusted EBITDA to be an important indicator of the Company’s operational strength and performance of its business and a good measure of the Company’s historical operating trend.

Adjusted EBITDA eliminates items that are either not part of the Company’s core operations, such as investment gains and losses, foreign exchange gains and losses, early debt extinguishment and net interest income, or do not require a cash outlay, such as stock-based compensation. Adjusted EBITDA also excludes depreciation and amortization expense, which is based on the Company’s estimate of the useful life of tangible and intangible assets. These estimates could vary from actual performance of the asset, are based on historic cost incurred to build out the Company’s deployed network, and may not be indicative of current or future capital expenditures.

Akamai defines “Adjusted EBITDA margin” as a percentage of Adjusted EBITDA as a percentage of revenues. Akamai considers Adjusted EBITDA margin to be an indicator of the Company’s operating trend and performance of its business in relation to its revenue growth.

Akamai defines “capital expenditures” or “capex” as purchases of property and equipment, capitalization of internal-use software development costs and capitalization of stock-based compensation. Capital expenditures or capex are disclosed in Akamai’s consolidated Statement of Cash Flows in the Company’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Akamai defines “normalized net income” as net income before amortization of other intangible assets, stock-based compensation expense, amortization of capitalized stock-based compensation, restructuring charges and benefits, certain gains and losses on investments, loss on early extinguishment of debt, utilization of tax NOLs/credits and release of the deferred tax asset valuation allowance. Akamai considers normalized net income to be another important indicator of the overall performance of the Company because it eliminates the effects of events that are either not part of the Company’s core operations or are non-cash.

Akamai defines “fully-taxed normalized net income” as normalized net income, excluding impact from utilization of tax NOLs/credits. Akamai considers fully-taxed normalized net income to be another important indicator of the overall performance of the Company because it eliminates the effects of events that are either not part of the Company’s core operations or are non-cash.

Akamai defines “diluted shares used in normalized net income per share calculation” as diluted common shares outstanding used in GAAP net income per share calculation, excluding the effect of stock-based compensation under the treasury stock method. Akamai considers normalized net income to be another important indicator of overall performance of the Company because it eliminates the effect of a non-cash item.

Adjusted EBITDA and normalized net income should be considered in addition to, not as a substitute for, the Company’s operating income and net income, as well as other measures of financial performance reported in accordance with GAAP.

Reconciliation of Non-GAAP Financial Measures

In accordance with the requirements of Regulation G issued by the Securities and Exchange Commission, the Company is presenting the most directly comparable GAAP financial measures and reconciling the non-GAAP financial metrics to the comparable GAAP measures.
