EARTHLINK ANNOUNCES FIRST QUARTER EARNINGS

Company Reports Record 15th Straight Quarter of
Value-Added Services Revenue Growth

ATLANTA, APRIL 26, 2007— EarthLink, Inc. (NASDAQ: ELNK) today announced financial results for its first quarter ended March 31, 2007.

Consolidated highlights for the quarter include:

·Consolidated revenue of $324.4 million

·Loss from operations of $(4.0) million

·Net loss of $(30.0) million, or $(0.24) per share, which includes a $(29.3) million, or $(0.24) per share Helio equity loss

·Adjusted EBITDA (a non-GAAP measure) of $17.2 million

 “In the first quarter, we recorded our 15th consecutive quarter of revenue growth from our value-added services, highlighted by the launch of our upgraded Protection Control Center with Attack Shield,” said Mike Lunsford, EarthLink interim CEO.  “We believe it is one of the best products on the market in fighting viruses and spyware.”

Lunsford added, “We also continued to make steady progress with our various growth initiatives as evidenced by our leadership position in municipal Wi-Fi networks, winning contracts in Houston and Corpus Christi, Tex. and Arlington, Va.  Additionally, we had our best quarter of growth to date for our DSL and Home Phone service bundle.”

EarthLink CFO Kevin Dotts said, “As we have undertaken our various growth initiatives and transitioned the company into a total communications provider, the company has realigned the internal financial reporting structure into two business units to more closely reflect current management of the business.  This quarter, the company has implemented segment reporting to reflect the recent change in how the business is reported to our management team.  I believe that the change will provide additional transparency to better allow investors to analyze results of operations.”

Operating and Financial Results

Under the company’s new segment format, the reportable segments consist of consumer services and business services.

Consumer services consist of Internet access and value-added services provided to individual customers.  Internet access is comprised of consumer narrowband and broadband access.  Consumer narrowband access includes premium EarthLink service and value PeoplePC service.  Broadband access includes consumer DSL, cable, satellite and municipal Wi-Fi access services, and voice services.  Consumer value-added services include portal advertising and audience engagement, search, subscriptions and partnership and distribution.

Business services consist of Internet access and value-added services provided to businesses and communications carriers.  Internet access consists of various narrowband and broadband Internet access products for single-site small office, home office (SOHO), and multi-site small and medium enterprises (SME).  Value-added services include web hosting domain registration fees.

In addition to the implementation of segment reporting, this quarter EarthLink has reclassified certain revenues between access and value-added services to more closely report these revenues to the internal management structure.  These revenues, primarily related to value-added security products sold by PeoplePC and home networking products and services, were previously reported in access and are now reported in value-added services.  Additionally, this quarter, EarthLink has also modified the way it counts subscribers related to the DSL and Home Phone service.  Previously, a customer that was subscribing to both of these services was classified as one subscriber.  Now, that customer will be counted as a DSL subscriber and a voice subscriber.  Finally, in this quarter, EarthLink has modified its definition for adjusted EBITDA to exclude stock-based compensation expense under SFAS

No. 123(R). This change will allow current results to be more comparable to periods prior to the adoption of SFAS No. 123(R) on January 1, 2006.

Please see the attached restated historical financial statements and subscriber metrics reflecting the impact of these new reporting formats.

EarthLink Revenue and Subscribers

For the quarter, consolidated revenues increased to $324.4 million, or 4.7 percent, compared to the first quarter of 2006.  This increase was driven primarily by growth in our business services, partially offset by a decline in our consumer services.

For the quarter, revenue from the business services segment increased from $18.2 million to $47.8 million primarily due to our acquisition of New Edge Networks in April 2006.

For the quarter, revenue from the consumer services segment decreased to $276.7 million, or 5.1 percent.  Contributing to this change was a $21.2 million, or 8.0 percent, decline in our access services driven by declines in mature premium narrowband services, partially offset by growth in our value narrowband and broadband access services.  Positively impacting consumer services was a $6.4 million, or 23.3 percent, increase in value-added services revenue.  Driving the increase in value-added services revenue was growth in the sales of security products, an increase in sales of higher revenue ad types and an increase in search RPMs (revenue per 1,000 searches).

During the first quarter of 2007, EarthLink’s overall subscribers declined by 42,000 net subscribers compared to the fourth quarter of 2006 primarily due to a decline in consumer access subscribers.  This decline in consumer access subscribers was related to a decline in premium narrowband subscribers, partially offset by growth in value, broadband and voice subscribers.

EarthLink Profitability and Other Financial Measures

EarthLink’s core access services continued to generate significant cash for reinvestment into our broadband growth initiatives.  During the quarter, adjusted EBITDA from core access services (a non-GAAP measure, see definition in “Non-GAAP Measures” below) was $47.3 million, a $2.7 million decline from the first quarter of 2006.  This decline was due to lower core access gross margin, partially offset by lower operating and sales and

marketing expenses in our core access services in the first quarter of 2007.  While EarthLink decreased spending in its more matures services, EarthLink increased spending in its strategic growth areas during the first quarter of 2007.  For the first quarter of 2007, EarthLink incurred $30.1 million of expense in the form of increased operating and marketing expenses compared to $17.0 million in the first quarter of 2006 in its growth initiatives.  This reinvestment is to further develop and market its broadband growth initiatives, including voice, municipal Wi-Fi and business services.  Consequently, for the first quarter of 2007, the adjusted EBITDA (a non-GAAP measure, see definition in “Non-GAAP Measures” below) was $17.2 million, a 48.1 percent decrease compared to the first quarter of 2006.

For the quarter, operating income from the consumer services segment was $25.6 million, a decrease of 11.3 percent compared to the prior year first quarter.  This decline reflects additional operating and sales and marketing expenditures related to launching and growing the voice and municipal Wi-Fi services while maintaining the existing narrowband and broadband access services.

For the quarter, operating income from the business services segment was $0.5 million, a decrease of $(10.8) million compared to the prior year first quarter. This decline reflects increased operating and sales and marketing expenditures related to launching various growth initiatives, primarily for New Edge Networks.  Due to the complex nature of selling and provisioning multi-location business broadband products, these products tend to have very long sales and installation cycles.  As such, current operating expenditures are not expected to generate benefits of increased customer and revenue growth for several quarters.

The increase in spending related to the growth initiatives noted above coupled with the Helio equity loss of $(29.3) million, resulted in a net loss for the quarter of $(30.0) million, or $(0.24) per share, compared to net income of $16.4 million, or $0.12 per share, in the prior year quarter.

Helio Operating Performance and Profitability

In the first quarter, Helio continued to grow its business and expand its service and device offerings.  During the quarter, Helio introduced Helio Music, a full mobile over-the air music download service with a rich browsing experience.  Helio also launched its fourth exclusive device — the Heat — featuring a slim, form factor design combined with Helio’s

line-up of 3G content and services.  Finally, at the cellular industry’s biggest tradeshow, Helio announced its flagship device — the Ocean, which should be available later this spring.  The Ocean will be the world’s first dual slide handset with two full numeric and QWERTY keypads.

 During the quarter, Helio continued to increase its subscriber base and is on track to surpass 100,000 members during the second quarter of 2007, as previously projected.  Additionally, in the first quarter of 2007, Helio generated $30.4 million in revenue, while Helio had not yet launched service in the first quarter of 2006.  Revenue for all of 2006 was $46.6 million.  Its net loss was $(63.1) million during the quarter, as it continued to make investments in infrastructure, products and marketing to support future growth.  Net of certain amortization related transactions, EarthLink’s proportionate share of Helio’s loss resulted in an equity loss of $(29.3) million compared to an equity loss of $(35.7) million in the fourth quarter of 2006.

EarthLink Balance Sheet and Cash Flow

As a result of the increase in activity related to EarthLink’s strategic growth initiatives, free cash flow (a non-GAAP measure, see definition in “Non-GAAP Measures” below) was $1.6 million during the first quarter of 2007 compared to $25.1 million in the first quarter of 2006.

During the first quarter, EarthLink made a scheduled capital contribution to Helio of $13.5 million and the company had capital expenditures of $13.7 million.  EarthLink ended the quarter with $367.4 million in cash and marketable securities, up 4.1 percent from the prior year first quarter.

Non-GAAP Measures

Adjusted EBITDA is defined as earnings before interest income and expense, income taxes, depreciation and amortization, stock-based compensation expense under SFAS No. 123(R), net losses of equity affiliate, gain on investments in other companies, net, and facility exit and restructuring costs.

Adjusted EBITDA from core access services is defined as earnings before interest income and expense, income taxes, depreciation and amortization, stock-based compensation expense under SFAS No. 123(R), net losses of equity affiliate, gain on

investments in other companies, net, facility exit and restructuring costs, and net investments in growth initiatives.

Free cash flow is defined as income from operations before facility exit and restructuring costs, stock-based compensation expense under SFAS No. 123(R), depreciation and amortization, less cash used for purchases of property and equipment and purchases of subscriber bases.

Adjusted EBITDA, adjusted EBITDA from core access services and free cash flow are non-GAAP financial performance measures.  They should not be considered in isolation or as an alternative to measures determined in accordance with U.S. generally accepted accounting principles.  Please refer to the Consolidated Financial Highlights for a reconciliation of these non-GAAP financial performance measures to the most comparable measures reported in accordance with U.S. generally accepted accounting principles and Footnote 1 of the Consolidated Financial Highlights for a discussion of the presentation, comparability and use of such financial performance measures.

Business Outlook

These statements are forward-looking, and actual results may differ materially.  See comments under “Cautionary Information Regarding Forward-Looking Statements” below.  EarthLink undertakes no obligation to update these statements.

EarthLink is revising its previously issued guidance for 2007.  Based on current results and expectations, EarthLink now expects year ending consolidated subscribers to decline by 200,000 to 250,000, and the company expects to generate approximately $1.3 billion in consolidated revenue.  The company is narrowing its previously issued guidance for adjusted EBITDA from core access services of $190.0 million to $200.0 million and $108.0 million to $118.0 million for adjusted EBITDA for the year. EarthLink is also narrowing its consolidated net loss to $(110.0) million to $(140.0) million for the year.

The company is reaffirming its previously issued guidance for Helio.  EarthLink expects Helio to end the year with 200,000 to 250,000 subscribers.  These subscribers are expected to be post-paid with an ARPU of $90 - $100.  For the year, EarthLink expects Helio will more than triple its revenue to $140.0 million to $170.0 million.  EarthLink expects that Helio’s cost structure to begin realizing the benefits of economies of scale, which should result in lower cost per gross add (CPGA ) and increased operating margins. 

As previously disclosed, EarthLink expects Helio will generate a net loss for the year of $(330.0) million to $(360.0) million, and EarthLink expects to record an equity loss of $(160.0) million to $(180.0) million reflecting its proportionate share of Helio’s expected net loss, net of certain amortization related transactions.

For the second quarter 2007, EarthLink expects consolidated revenues to be $315.0 million to $320.0 million, and adjusted EBITDA to be $28.0 million to $33.0 million. EarthLink expects to record a net loss of $(16.0) million to $(26.0) million for the quarter driven by a Helio equity loss of $(35.0) million to $(40.0) million.

Footnotes to Consolidated Financial Highlights

1.Earnings before interest income and expense, income taxes, depreciation and amortization, stock-based compensation under SFAS No. 123(R), net losses of equity affiliate, gain on investments in other companies, net, and facility exit and restructuring costs (Adjusted EBITDA); earnings before interest income and expense, income taxes, depreciation and amortization, stock-based compensation under SFAS No. 123(R), net losses of equity affiliate, gain on investments in other companies, net, facility exit and restructuring costs, and net investments in growth initiatives (Adjusted EBITDA from Core Access Services); and free cash flow are non-GAAP measures and are not determined in accordance with U.S. generally accepted accounting principles. These financial performance measures are not indicative of cash provided or used by operating activities and may differ from comparable information provided by other companies, and they should not be considered in isolation, as an alternative to, or more meaningful than measures of financial performance determined in accordance with U.S. generally accepted accounting principles. These financial performance measures are commonly used in the industry and are presented because EarthLink believes they provide relevant and useful information to investors. EarthLink utilizes these financial performance measures to assess its ability to meet future capital expenditures and working capital requirements, to incur indebtedness if necessary, and to fund continued growth. EarthLink also uses these financial performance measures to evaluate the performance of its business, for budget planning purposes and as factors in its employee compensation programs.  Since the elements of these financial performance measures are determined using the accrual basis of accounting and exclude the effects of certain capital, financing, acquisition-related, and facility exit and restructuring costs, investors should use them to analyze and compare companies on the basis of current period operating performance.

2.EarthLink’s business segments are strategic business units that are managed based upon differences in customers, services and marketing channels. EarthLink’s Consumer Services segment is a provider of integrated communications services and related value-added services to individual customers. These services include dial-up Internet access, high-speed Internet access, municipal wireless broadband and voice service, among others. EarthLink’s Business Services segment is a provider of integrated communications services and related value-added services to businesses and communications carriers. These services include managed data networks, dedicated Internet access and web hosting, among others.

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), amortization of intangible assets and stock-based compensation expense under SFAS No. 123(R), as they are not evaluated in the measurement of segment performance.

3.Represents full-time equivalents.

4.Subscriber counts do not include nonpaying customers. Customers receiving service under promotional programs that include periods of free service at inception are not included in subscriber counts until they become paying customers.

5.Paying customers who subscribe to EarthLink DSL and Home Phone service are counted as both a broadband subscriber and a voice subscriber.

6Churn 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.

7.Average subscribers or accounts 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.

8.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.
