Continued Improvement in Revenue Trajectory

ATLANTA — August 2, 2012 — EarthLink, Inc. (NASDAQ: ELNK) today announced financial results for its second quarter ended June 30, 2012.

Highlights for the second quarter include:

·                  Net loss of $(1.1) million or $(0.01) per share

·                  Adjusted EBITDA (a non-GAAP measure) of $66.4 million

·                  Net cash provided by operating activities of $22.2 million

·                  Unlevered free cash flow (a non-GAAP measure) of $41.9 million

·                  Ending cash and marketable securities of $258.0 million

These results include an $8.3 million increase in reserves for regulatory audits.

“We are making good progress in the transformation of platforms, products and people to position EarthLink for long-term success as an IT services company,” said EarthLink Chairman and Chief Executive Officer Rolla P. Huff.   “Our business is trending in the right direction towards growth. We continue to invest in IT services and integration to support our future, while evolving our organizational structure and distribution channels to fuel our growth.”

Financial and Operating Results

EarthLink reported total company revenue of $338.2 million in the second quarter of 2012, a 2% decrease from the prior quarter and a 7% decrease from the year-ago quarter.  Business services comprised 76% of EarthLink’s revenue in the second quarter of 2012, up from 74% in the year-ago quarter. Business services revenue declined $2.8 million, or 1%, from the

1

prior quarter, narrowing the declines in this segment. The company’s consumer services segment continues to perform well, with higher-margin broadband services accounting for 68% of consumer access revenue in the second quarter of 2012, up from 67% in the prior quarter and 65% in the year-ago quarter. Subscriber churn in the consumer segment was 2.3% in the second quarter of 2012, as compared to 2.5% in the prior quarter and 2.6% in the year-ago quarter.

EarthLink’s selling, general and administrative expenses were $106.4 million, or 31% of revenue, in the second quarter of 2012, as compared to expenses of $110.1 million in the prior quarter and $113.8 million in the year-ago quarter.

Profitability and Other Financial Measures

Net loss was $(1.1) million, or $(0.01) per share, in the second quarter of 2012, as compared to net income of $7.3 million, or $0.07 per share, in the prior quarter, and $6.5 million, or $0.06 per share, in the year-ago quarter.

EarthLink generated Adjusted EBITDA (a non-GAAP measure, see definition in “Non-GAAP Measures” below) of $66.4 million in the second quarter of 2012, versus Adjusted EBITDA of $77.6 million in the prior quarter and $88.9 million in the year-ago quarter.

EarthLink’s second quarter 2012 net loss and Adjusted EBITDA reflect an $8.3 million charge recorded within cost of revenue to increase the company’s reserves for regulatory audits, primarily an audit currently being conducted by the Universal Service Administration Company on Federal Universal Service Fund assessments and payments in the legacy ITC^DeltaCom business.

Balance Sheet and Cash Flow

Net cash provided by (used in) operating activities was $22.2 million during the second quarter of 2012, compared to $66.2 million in the prior quarter and ($9.0) million in the year-ago quarter. EarthLink generated unlevered free cash flow (a non-GAAP measure, see definition in “Non-GAAP Measures” below) of $41.9 million during the second quarter of 2012, compared to $45.9 million in the prior quarter and $66.2 million in the year-ago quarter.

As of June 30, 2012, the company reported cash and marketable securities of $258.0 million. Capital expenditures were $24.5 million for the second quarter of 2012. During the second quarter of 2012, the company made $5.3 million of dividend payments to shareholders,

Organizational Announcement

Cautionary Information Regarding Forward-Looking Statements

This press release includes “forward-looking” statements (rather than historical facts) that are subject to risks and uncertainties that could cause actual results to differ materially from those described. Although we believe that the expectations expressed in these forward-looking statements are reasonable, we cannot promise that our expectations will turn out to be correct. Our actual results could be materially different from and worse than our expectations. With respect to such forward-looking statements, we seek the protections afforded by the Private Securities Litigation Reform Act of 1995. These risks include (1) that we may not be able to execute our strategy to grow our business services revenue, especially revenue from advanced products, in an expeditious manner, which could

4

adversely impact our results of operations and cash flows; (2) that we may be unsuccessful or experience delays in integrating acquisitions into our business while we develop our Business Services advanced product portfolio, which could result in operating difficulties, losses and other adverse consequences; (3) that we may be unable to successfully identify, manage and assimilate future acquisitions, which could adversely affect our results of operations; (4) that if we are unable to adapt to changes in technology and customer demands, we may not remain competitive, and our revenues and operating results could suffer; (5) that our failure to achieve operating efficiencies will adversely affect our results of operations; (6) that unfavorable general economic conditions could harm our business; (7) that we face significant competition in the communications and managed IT services industry that could reduce our profitability; (8) that decisions by the Federal Communications Commission relieving incumbent carriers of certain regulatory requirements, and possible further deregulation in the future, may restrict our ability to provide services and may increase the costs we incur to provide these services; (9) that if we are unable to interconnect with AT&T, Verizon and other incumbent carriers on acceptable terms, our ability to offer competitively priced local telephone services will be adversely affected; (10) that our operating performance will suffer if we are not offered competitive rates for the access services we need to provide our long distance services; (11) that we may experience reductions in switched access and reciprocal compensation revenue; (12) that failure to obtain and maintain necessary permits and rights-of-way could interfere with our network infrastructure and operations; (13) that we have substantial business relationships with several large telecommunications carriers, and some of our customer agreements may not continue due to financial difficulty, acquisitions, non-renewal, or other factors, which could adversely affect our revenue and results of operations; (14) that our commercial and alliance arrangements may not be renewed or may not generate expected benefits, which could adversely affect our results of operations;  (15) that our consumer business is dependent on the availability of third-party network service providers; (16) that we face significant competition in the Internet industry that could reduce our profitability; (17) that the continued decline of our consumer access subscribers, combined with the change in mix of our consumer access base from narrowband to broadband, will adversely affect our results of operations; (18) that potential regulation of Internet service providers could adversely affect our operations; (19) that we may be unable to hire and retain sufficient qualified personnel, including Business Services sales personnel, and that the loss of any of our key executive officers could adversely affect us;

(22) that interruption or failure of our network and information systems and other technologies could impair our ability to provide our services, which could damage our reputation and harm our operating results; (23) that our business depends on effective business support systems and processes; (24) that government regulations could adversely affect our business or force us to change our business practices and that we are subject to regulatory audits; (25) that our business may suffer if third parties are unable to provide services or terminate their relationships with us; (26) that we may not be able to protect our intellectual property; (27) that we may be accused of infringing upon the intellectual property rights of third parties, which is costly to defend and could limit our ability to use certain technologies in the future; (28) that if we are unable to successfully defend against legal actions, we could face substantial liabilities or suffer harm to our financial and operational prospects; (29) that we may be required to recognize additional impairment charges on our goodwill and intangible assets, which would adversely affect our results of operations and financial position; (30) that we may have exposure to greater than anticipated tax liabilities and the use of our net operating losses and certain other tax attributes could be limited in the future; (31) that our indebtedness could adversely affect our financial health and limit our ability to react to changes in our industry;

Footnotes to Consolidated Financial Highlights

(1)               On April 1, 2011, EarthLink completed its acquisition of One Communications, a privately-held, multi-regional integrated telecommunications solutions provider serving customers in the Northeast, Mid-Atlantic and Upper Midwest. The results of operations of One Communications have been included in EarthLink’s consolidated financial statements since the acquisition date.

(2)               Restructuring, acquisition and integration-related costs consisted of the following for the periods presented (in thousands):

Acquisition and integration-related costs consist of costs directly related to EarthLink’s acquisitions, such as advisory, legal, accounting, valuation and other professional fees; employee severance and retention costs; facility-related costs, such as lease termination and asset impairments; and integration-related costs, such as system conversion, rebranding costs and integration related consulting and employee costs.  EarthLink expects to incur approximately $7.0 million and $4.0 million of acquisition and integration-related costs in the third quarter of 2012 and fourth quarter of 2012, respectively.

Facility exit and restructuring costs consist of costs incurred for EarthLink’s restructuring plans. In August 2007, EarthLink adopted a restructuring plan (the “2007 Plan”) to reduce costs and improve the efficiency of the Company’s operations. The 2007 Plan was the result of a comprehensive review of operations within and across the Company’s functions and businesses. Under the 2007 Plan, the Company reduced its workforce by approximately 900 employees, closed office facilities in Orlando, Florida; Knoxville, Tennessee; Harrisburg, Pennsylvania; and San Francisco, California and consolidated its office facilities in Atlanta, Georgia and Pasadena, California. The 2007  Plan was primarily implemented during 2007 and 2008. However, there have been and may continue to be changes in estimates to amounts previously recorded.

(3)               Adjusted EBITDA is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation, impairment of goodwill and intangible assets, and restructuring, acquisition and integration-related costs.  Unlevered Free Cash Flow is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation, impairment of goodwill and intangible assets, and restructuring, acquisition and integration-related costs, less purchases cash used for of property and equipment.

Adjusted EBITDA and Unlevered Free Cash Flow are non-GAAP measures and are not determined in accordance with U.S. generally accepted accounting principles. These non-GAAP financial measures are commonly used in the industry and are presented because management believes they provide relevant and useful information to investors. Management uses these non-GAAP financial measures to evaluate the performance of its business and determine bonuses. Management believes that excluding the effects of certain non-cash and non-operating items enables investors to better understand and analyze the current period’s results and provides a better measure of comparability. There are limitations to using these non-GAAP financial measures. Adjusted EBITDA and Unlevered Free Cash Flow are not indicative of cash provided or used by operating activities and may differ from comparable information provided by other companies.  Adjusted EBITDA and Unlevered Free Cash Flow should not be considered in isolation, as an alternative to, or more meaningful than measures of financial performance determined in accordance with U.S. GAAP.

(4)               The Company reports segment information along the same lines that its chief executive officer reviews its operating results in assessing performance and allocating resources. The Company operates two reportable segments, Business Services and Consumer Services . The Company’s Business Services segment provides a comprehensive suite of communications and technology services, including voice, data, managed network services, cloud hosting and equipment services, to business customers. The Company’s Consumer Services segment provides nationwide Internet access and related value-added services to residential customers.

The Company presents its Business Services revenue in the following three categories: (1) retail services, which includes data, voice and managed IT services; (2) wholesale services, which includes the sale of transmission capacity to other telecommunications carriers; and (3) other services, which includes the sale of customer premises equipment and web hosting. The Company presents its Consumer Services revenue in the following two categories: (1) access services, which includes include narrowband and broadband Internet access services and (2) value-added services, which includes revenues from ancillary services sold as add-on features to EarthLink’s Internet access services, such as security products, premium email only, home networking, email storage and Internet call waiting; search revenues; and advertising revenues.

EarthLink evaluates performance of its operating segments based on segment income from operations. Segment income from operations includes revenues from external customers, related cost of revenues and operating expenses directly attributable to the segment, which include expenses over which segment managers have direct discretionary control, such as advertising and marketing programs, customer support expenses, site operations expenses, product development expenses, certain technology and facilities expenses, billing operation and provisions for doubtful accounts. Segment income from operations excludes other income and expense items and certain expenses that segment managers do not have discretionary control over. Costs excluded from segment income from operations include various corporate expenses (consisting of certain costs such as corporate management, human resources, finance and legal), depreciation and amortization, stock-based compensation expense, impairment of goodwill and intangible assets and restructuring, acquisition and integration-related costs, as they are not evaluated in the measurement of segment performance.

(5)               Debt represents the principal amount of EarthLink’s Senior Notes, EarthLink’s Convertible Senior Notes and ITC^DeltaCom’s Senior Secured Notes. Below is a summary of the carrying amount of EarthLink’s debt (in thousands):

(6)               Represents full-time equivalents.

(7)               As of June 30, 2011, includes 12,559 route miles owned or obtained through indefeasible rights to use (IRU) and 3,945 marketed and managed route miles.

(8)               Average subscribers for the three month periods is calculated by averaging the ending monthly subscribers or accounts for the four months preceding and including the end of the quarterly period.  Average subscribers for the six month periods is calculated by averaging the ending monthly subscribers or accounts for the seven months preceding and including the end of the period.

(9)               ARPU represents the average monthly revenue per user (subscriber). ARPU is computed by dividing average monthly revenue for the period by the average number of subscribers for the period. Average monthly revenue used to calculate ARPU includes recurring service revenue as well as nonrecurring revenues associated with equipment and other one-time charges associated with initiating or discontinuing services.

(10)   Churn rate is used to measure the rate at which subscribers discontinue service on a voluntary or involuntary basis.  Churn rate is computed by dividing the average monthly number of subscribers that discontinued service during the period by the average subscribers for the period.
