Protecting Consumer Privacy

Akamai already powers the online efforts of many of the Internet’s largest publishers and ad networks, as well as hundreds of leading consumer brands. Akamai’s Advertising Decision Solutions will build on the company’s unique and trusted position in the online industry.

As members of the Network Advertising Initiative (NAI), Akamai and acerno are committed to maintaining both user privacy and customer confidentiality. All of Akamai’s Advertising Decision Solutions, as well as acerno’s services, rely solely on anonymous and non-personally identifiable end user information.

“Akamai’s new Advertising Decision Solutions are a critical advancement in our product portfolio, designed to stimulate the economic model of online advertising by bringing greater simplicity and effectiveness to both ad buyers and sellers,” said Paul Sagan, president and CEO of Akamai. “As a trusted and strategic partner to today’s leading online retailers, publishers, and advertisers, supporting an estimated $84 billion in e-commerce transactions on our network for U.S. retailers alone, Akamai’s goal is to offer the industry’s most efficient online advertising solutions, while being a leader in upholding consumer privacy.

The release contains information about future expectations, plans and prospects of Akamai’s management that constitute forward-looking statements for purposes of the safe harbor provisions under The Private Securities Litigation Reform Act of 1995, including statements about new services to be offered by Akamai, the anticipated closing of the acquisition, the expectations with respect to benefits and the expected future business and financial performance of Akamai resulting from and following the acquisition. Actual results may differ materially from those indicated by these forward-looking statements as a result of various important factors including, but not limited to, inability to successfully integrate the technology of acerno or to develop services based on the technology, material adverse changes in the financial conditions or operations of acerno, substantial delay in the expected closing of the proposed merger, inability to secure all consents and stockholder approvals necessary to effect the proposed merger and other factors that are discussed in the Company’s Annual Report on Form 10-K, quarterly reports on Form 10-Q, and other documents periodically filed with the SEC.

* 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 non-GAAP financial metrics we have mentioned are useful to management and investors because they provide additional insight into our operations as well as help us assess and monitor developments in our business. Set forth below are definitions of the non-GAAP term we used and explanation of some of the benefits provided by this metric.

Akamai defines “normalized earnings” as net income before amortization of intangible assets, equity-related compensation, depreciation of capitalized equity-related compensation, certain gains and losses on equity investments, utilization of tax NOLs/credits and release of the deferred tax asset valuation allowance. Akamai

considers normalized earnings 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.
