LIMELIGHT NETWORKS^™ REPORTS FIRST QUARTER 2009 RESULTS

• Revenue of $33.2 million, a 10% increase from first quarter 2008

• Reversal of $66 million accrual due to favorable ruling from Federal District Court of Massachusetts

• Launch of LimelightSITE^™ with over 150 customers, entry into enterprise and e-commerce sectors

• Addition of approximately 35 net new customers

TEMPE, AZ. – 6 MAY 2009 – Limelight Networks, Inc. (Nasdaq: LLNW) today reported first quarter 2009 financial results.

“Limelight Networks achieved solid year-over-year revenue growth during the first quarter. We continued to see strong demand for our core content delivery and storage services, and were pleased with the market reception for LimelightSITE and a favorable ruling in our patent litigation with Akamai. We believe that continued Internet adoption presents us with attractive growth opportunities and that our eight years of innovation, our global scale and our network-based architecture are the optimal solution for publishers, enterprises, and governments advancing their online presence,” commented Jeff Lunsford, chairman and chief executive officer, Limelight Networks, Inc.

Financial Highlights

For the first quarter of 2009, the company reported revenue of $33.2 million, up 10% percent from $30.2 million in the same period last year, and EBITDA, adjusted for share-based compensation, litigation and the reversal of a previously recorded damage accrual, of $4.7 million.

Non-GAAP net loss, before stock based compensation, litigation costs, and reversal of a previously recorded damage accrual, was $2.1 million or 2 cents per basic share. GAAP net earnings were $55.1 million, or 66 cents per basic share and 64 cents on a fully-diluted basis. These earnings include the reversal of a previously recorded damage accrual of $66 million as a result of the Massachusetts Federal District Court order finding that we do not infringe the Akamai 703 patent.

Capital purchases incurred were $4.6 million. The Company ended the quarter with no bank debt and approximately $162 million in cash and short-term marketable securities. A reconciliation of GAAP to non-GAAP net income is included in the attached tables.

Second-Quarter Outlook

Limelight Networks anticipates second quarter revenue to be in the range of $32.2 million to $33.2 million.

Use of Non-GAAP Financial Measures

To evaluate our business, we consider and use Non-GAAP net income and EBITDA adjusted for share-based compensation and litigation and damage costs as a supplemental measure of operating performance. We consider Non-GAAP net income to be an important indicator of overall business performance because it allows us to illustrate the impact of the effects of share-based compensation, litigation expenses and provision for litigation. We define EBITDA as GAAP net income before interest income, interest expense, other income and expense, provision for income taxes, depreciation and amortization. We define EBITDA adjusted for share-based compensation and litigation and damage costs as EBITDA plus expenses that we do not consider reflective of our ongoing operations. We use EBITDA adjusted for share-based compensation and litigation and damage costs as a supplemental measure to review and assess operating performance. We also believe use of EBITDA adjusted for share-based compensation and litigation and damage costs facilitates investors’ use of operating performance comparisons from period to period.

The terms Non-GAAP net income, EBITDA and EBITDA adjusted for share-based compensation and litigation and damage costs are not defined under U.S. generally accepted accounting principles, or U.S. GAAP, and are not measures of operating income, operating performance or liquidity presented in accordance with U.S. GAAP. Our Non-GAAP net income, EBITDA and EBITDA adjusted for share-based compensation and litigation and damage costs have limitations as analytical tools, and when assessing our operating performance, Non-GAAP net income, EBITDA and EBITDA adjusted for share-based compensation and litigation and damage costs should not be considered in isolation, or as a substitute for net income (loss) or other consolidated income statement data prepared in accordance with U.S. GAAP. Some of these limitations include, but are not limited to:

• EBITDA and EBITDA adjusted for share-based compensation and litigation and damage costs do not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;

• they do not reflect changes in, or cash requirements for, our working capital needs;

• they do not reflect the cash requirements necessary for litigation costs;

• they do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debt;

• they do not reflect income taxes or the cash requirements for any tax payments;

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will be replaced sometime in the future, and EBITDA and EBITDA adjusted for share-based compensation and litigation and damage costs do not reflect any cash requirements for such replacements;

• while share-based compensation is a component of operating expense, the impact on our financial statements compared to other companies can vary significantly due to such factors as the assumed life of the options and the assumed volatility of our common stock; and

• other companies may calculate EBITDA and EBITDA adjusted for share-based compensation and litigation and damage costs differently than we do, limiting their usefulness as comparative measures.

We compensate for these limitations by relying primarily on our GAAP results and using Non-GAAP Net Income and EBITDA adjusted for share-based compensation and litigation and damage costs only as supplemental support for management’s analysis of business performance. Non-GAAP Net Income, EBITDA and EBITDA adjusted for share-based compensation and litigation and damage costs are calculated as follows for the periods presented in thousands:
