ATLANTA, GA — August 4, 2014 — EarthLink Holdings Corp. (NASDAQ: ELNK) today announced financial results for its second quarter of 2014.

“I’m proud of our strong financial results we delivered this quarter,” said EarthLink Chief Executive Officer and President Joseph F. Eazor. “We are intensely focused on improving our operations and cash flow generation. Our results this quarter reflect the team’s good progress so far. We are still early in this process and we expect to continue to make additional run rate improvements.”

Second Quarter 2014 Financial Summary

(1) Q1 2014 Adjusted Net Loss excludes a one-time fixed asset impairment of $5.3 million and Q2 2014 Adjusted Net Loss excludes a one-time fixed asset impairment of $5.4 million.

(2) Adjusted Net Loss, Adjusted Net Loss per Share, Adjusted EBITDA and Unlevered Cash Flow are non-GAAP measures, see definitions in “Non-GAAP Measures” below.

Revenue

·                  EarthLink’s total revenue for the second quarter of 2014 was $297.4 million, a decline of 5.1% from the prior year quarter. The revenue trajectory continued to show improvement versus the 6.1% year-over-year decline the company reported in the first quarter of 2014.

2

·                  Business Services revenue declined 3.7% from the second quarter of 2013, an improvement versus the 4.3% year-over-year decline reported in the first quarter of 2014. The company’s sales teams continued to make progress extending the terms of contracts with existing customers.

·                  The Consumer Services revenue profile was aided by targeted price actions during the quarter. Consumer Services churn in the second quarter is commensurate with an increase in ARPU. We expect consumer churn to continue to moderate in future periods.

Net Loss and Adjusted EBITDA

·                  Net loss was $(21.8) million in the second quarter. This amount includes one-time non-cash charges of $5.4 million to record impairment of certain fixed assets. This compares to a net loss of $(11.2) million in the second quarter of 2013 and $(26.5) million in the first quarter of 2014.

·                  Adjusted EBITDA (a non-GAAP measure, see definition in “Non-GAAP Measures” below) was $50.9 million in the second quarter, a 2% increase from the first quarter of 2014, and a 15% decrease from the second quarter of 2013.

Balance Sheet and Cash Flow

·                  Net cash provided by operating activities was $18.0 million. EarthLink ended the second quarter with $98.5 million in cash. This compared to net cash provided by operating activities of $11.7 million in the second quarter of 2013 and $21.3 million in the first quarter of 2014. EarthLink made interest payments of $24.5 million during the second quarter and repurchased 0.7 million shares of common stock for $2.2 million.

·                  EarthLink generated Unlevered Free Cash Flow (a non-GAAP measure, see definition in “Non-GAAP Measures” below) of $24.9 million during the second quarter of 2014.  This compared to Unlevered Free Cash Flow of $25.1 million in the second quarter of 2013 and $26.5 million in the first quarter of 2014.

Footnotes to Consolidated Financial Highlights

1.              During the first quarter of 2013, the Company recognized a $256.7 million non-cash impairment charge to goodwill related to its Business Services reporting unit, of which $255.6 million is included in continuing operations and $1.1 million is reflected in discontinued operations. The impairment was based on an analysis of a number of factors after a decline in the Company’s market capitalization following the announcement of its fourth quarter 2012 earnings and 2013 financial guidance. The primary factor contributing to the impairment was a change in the discount rate and market multiples as a result of the change in these market conditions, both key assumptions used in the determination of fair value.

During the six months ended June 30, 2014, the Company recorded $10.8 million for impairment of property and equipment, which included $5.3 million recorded during the three months ended March 31, 2014 for impairment of work in progress for an information technology project not expected to be used and $5.4 million recorded during the three months ended June 30, 2014 for impairment of work in progress and software licenses not expected to be used.

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

Restructuring, acquisition and integration-related costs consist of costs related to restructuring, acquisition and integration-related activities. Such costs include: 1) integration-related costs, such as system conversion, rebranding costs and integration-related consulting and employee costs; 2) severance, retention and other employee termination costs associated with acquisition and integration activities and with certain voluntary employee separations; 3) facility-related costs, such as lease termination and asset impairments; and 4) transaction-related costs, which are direct costs incurred to effect a business combination, such as advisory, legal, accounting, valuation and other professional fees.

3.              The operating results of the Company’s telecom systems business acquired as part of ITC^DeltaCom have been separately presented as discontinued operations for all periods presented. On August 2, 2013, the Company sold its telecom systems business. The Company has no significant continuing involvement in the operations or significant continuing direct cash flows. The telecom systems results of operations were previously included in the Company’s Business Services segment.

4.              Adjusted EBITDA is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation expense, impairment of goodwill and long-lived assets, restructuring, acquisition and integration-related costs, and gain (loss) from discontinued operations, net of tax. Unlevered Free Cash Flow is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation expense, impairment of goodwill and long-lived assets, restructuring, acquisition and integration-related costs, and gain (loss) from discontinued operations, net of tax, less cash used for purchases of property and equipment. Adjusted Net Loss is defined as net loss excluding the non-cash charge to record a valuation allowance against deferred tax assets, the non-cash impairment of goodwill and estimated tax impact and the non-cash impairment of long-lived assets.

Adjusted EBITDA, Unlevered Free Cash Flow and Adjusted Net Loss 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, Unlevered Free Cash Flow and Adjusted Net Loss are not indicative of cash provided or used by operating activities and may differ from comparable information provided by other companies.  Adjusted EBITDA, Unlevered Free Cash Flow and Adjusted Net Loss 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.

5.              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 broad range of data, voice and IT services to retail and wholesale 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 IT services provided to business customers; (2) wholesale services, which includes the sale of transmission capacity to other telecommunications carriers and businesses; and (3) other services, which primarily consists of web hosting. The Company’s IT services, which are included within its retail services, include data centers, virtualization, security, applications, premises-based solutions, managed solutions and support services. The Company presents its Consumer Services revenue in the following two categories: (1) access services, which includes 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 and email storage; 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.

6.              Represents full-time equivalents.

7.              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.

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.

9.              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.
