EARTHLINK ANNOUNCES THIRD QUARTER 2009 RESULTS

ATLANTA – October 27, 2009 – EarthLink, Inc. (NASDAQ: ELNK) today announced financial results for its third quarter ended September 30, 2009.  Highlights for the third quarter include:

·                   Net income of $29.9 million or $0.28 per share

·                   Adjusted EBITDA (a non-GAAP measure) of $60.9 million

·                   Free cash flow (a non-GAAP measure) of $55.3 million

·                   Ending cash and marketable securities balance of $654.9 million

·                   Increased and narrowed full year 2009 Adjusted EBITDA (a non-GAAP measure) guidance to $243 million - $248 million

“We are pleased with our third quarter operating performance,” stated EarthLink Chairman and Chief Executive Officer Rolla P. Huff. “Adjusted EBITDA, free cash flow and net income all came in at the high end of our estimates and as a result, we are slightly raising our full year 2009 guidance. This increased guidance includes the cost of fourth quarter productivity enhancements and the resulting cost rightsizing that continues to occur in our business. These fourth quarter initiatives are part of our ongoing and proactive efforts to reduce our cost structure.”

“Last week, we announced the approval of our second consecutive quarterly dividend payment,” added Huff. “We believe our financial strength and future cash flow continue to provide our company meaningful flexibility in considering value creating options for our shareholders.”

Financial and Operating Results

Revenue for the third quarter of 2009 was $174.5 million, a decline of 6 percent from the second quarter of 2009 and 24 percent from the year-ago quarter. The pace of revenue declines in EarthLink’s consumer business continues to decelerate as this quarter the company reported single digit million dollar sequential revenue declines in its consumer segment.

EarthLink reported net subscriber losses of 146,000 for the quarter, a decrease from 149,000 in the second quarter of 2009 and 275,000 in the year-ago quarter.   Subscriber churn was flat with the second quarter of 2009 at 3.6%, and an improvement from 4.2% in the third quarter of 2008.

These trends represent the increasing tenure of EarthLink’s customer base and ongoing shift to broadband products offsetting seasonally lower churn in the second quarter. In the third quarter of 2009, 80% of EarthLink’s consumer customers had two or more years of tenure with the company, nearly 40% had five or more years of tenure, and broadband products comprised 57% of EarthLink’s revenue.

Total sales and marketing, operations, customer support, and general and administrative expenses for the third quarter were $53.9 million, down 2 percent versus the prior quarter and 32 percent from the year-ago quarter. EarthLink continues to invest opportunistically in select marketing channels which are generating positive lifetime value customers and to implement cost reduction initiatives to align costs with the revenue trends.

Profitability and Other Financial Measures

EarthLink realized $29.9 million, or $0.28 per share, of income from continuing operations in the third quarter of 2009, down from $31.5 million, or $0.29 per share, in the second quarter of 2009, and from $52.6 million, or $0.47 per share, in the third quarter of 2008.

Net income was $29.9 million, or $0.28 per share, for the third quarter of 2009 as compared to $31.5 million, or $0.29 per share, in the prior quarter, and $51.9 million, or $0.46 per share, in the year-ago quarter. Included in the change from the year-ago quarter was a $9.0 million increase in the company’s income tax provision, primarily due to an increase in non-cash deferred taxes resulting from the use of the company’s net operating loss carryforwards (NOLs) and a $4.3 million decrease in gain on investments, net.

The decelerating revenue declines, combined with continued reductions in cost of revenues, sales and marketing and back office support expenses resulted in EarthLink generating Adjusted EBITDA (a non-GAAP measure, see definition in “Non-GAAP Measures” below) of $60.9 million for the third quarter of 2009, as compared to $68.5 million in the second quarter of 2009 and $74.0 million in the third quarter of 2008.

Balance Sheet and Cash Flow

Free cash flow (a non-GAAP measure, see definition in “Non-GAAP Measures” below) was $55.3 million during the third quarter of 2009, compared to $66.6 million during the second quarter of 2009 and $71.6 million in the third quarter of 2008. During the quarter, EarthLink made $15.0 million of dividend payments and had capital expenditures of $5.6 million. EarthLink ended the third quarter with $654.9 million in cash and marketable securities, an increase of $44.5 million from June 30, 2009.

Business Outlook

The following 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.

Today Earthlink is raising and narrowing the ranges on its previously announced guidance for the full year 2009.  Management now expects 2009 Adjusted EBITDA of $243 million to $248 million and 2009 free cash flow of $225 million to $235 million, based upon the aforementioned Adjusted EBITDA guidance combined with $13 million to $18 million in estimated capital expenditures. Additionally, EarthLink now expects to generate income from continuing operations of $110 million to $115 million for full year 2009.

Payment of Quarterly Dividend

On October 21, 2009, EarthLink announced that its Board of Directors had approved payment of its quarterly cash dividend on its common stock in the amount of $0.14 per share to be paid on December 23, 2009 to shareholders of record on December 9, 2009.

Non-GAAP Measures

Adjusted EBITDA is defined as income from continuing operations before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation expense, gain (loss) on investments, net, impairment of goodwill and intangible assets, and facility exit and restructuring costs.
