“We have grown our recurring customer base by 46 percent year-over-year,” Sagan said. “This is the result of momentum in important industries that increasingly rely on the Internet, including media and entertainment, online commerce, and software distribution, as well as adoption by major enterprises of our new application acceleration technology.”

*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). Recent 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 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. This measure is also used by management in their financial and operating decision-making.

Akamai defines “Adjusted EBITDA” as net income, before interest, taxes, depreciation, amortization, equity-related compensation, restructuring charges and benefits, certain gains and losses on equity investments, foreign exchange gains and losses, release of the deferred tax asset valuation allowance and loss on early extinguishment of debt. 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 expense, or do not require a cash outlay, such as equity-related compensation and impairment of intangible assets. 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 over revenue. 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 and capitalization of internal-use software development costs. Capital expenditures or capex are disclosed in Akamai’s condensed 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 intangible assets, equity-related compensation, certain gains and losses on equity investments, release of the deferred tax asset valuation allowance and loss on early extinguishment of debt. 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.

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 measure and reconciling the non-GAAP financial metrics to the comparable GAAP measures.
