The risks and uncertainties to which the forward-looking statements are subject additionally include, without limitation: (1) that we may not be able to execute our strategy to successfully transition to a leading managed network, security and cloud services provider, which could adversely affect our results of operations and cash flows; (2) that we may not be able to

increase revenues from our growth products and services to offset declining revenues from our traditional products and services, which could adversely affect our results of operations and cash flows; (3) 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; (4) that failure to achieve operating efficiencies and otherwise reduce costs would adversely affect our results of operations and cash flows; (5) that we may have to undertake further restructuring plans that would require additional charges; (6) that we may be unable to successfully divest non-strategic products, which could adversely affect our results of operations; (7) that acquisitions we complete could result in operating difficulties, dilution, increased liabilities, diversion of management attention and other adverse consequences, which could adversely affect our results of operations;

(10) that decisions by legislative or regulatory authorities, including 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; (11) 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; (12) that the continued decline in switched access and reciprocal compensation revenue will adversely affect our results of operations; (13) that failure to obtain and maintain necessary permits and rights-of-way could interfere with our network infrastructure and operations;

(18) that our consumer business is dependent on the availability of third-party network service providers; (19) that we face significant competition in the Internet access industry that could reduce our profitability; (20) that the continued decline of our consumer access subscribers will adversely affect our results of operations; (21) that lack of regulation governing wholesale Internet service providers could adversely affect our operations; (22) that cyber security breaches could harm our business; (23) that privacy concerns relating to our business could damage our reputation and deter current and potential users from using our services; (24) that interruption or failure of our network, information systems or other technologies could impair our ability to provide our services, which could damage our reputation and harm our operating results; (25) that our business depends on effective business support systems and processes; (26) that if we, or other industry participants, are unable to successfully defend against disputes or legal actions, we could face substantial liabilities or suffer harm to our financial and operational prospects; (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 we may not be able to protect our intellectual property; (29) that we may be unable to hire and retain sufficient qualified personnel, and the loss of any of our key executive officers could adversely affect us; (30) that unfavorable general economic conditions could harm our business; (31) that government regulations could adversely affect our business or force us to change our business practices; (32) that our business may suffer if third parties are unable to provide services or terminate their relationships with us; (33) that we may be required to recognize impairment charges on our goodwill and other intangible assets, which would adversely affect our results of operations and financial position; (34) that we may have exposure to greater than anticipated tax liabilities and we may be limited in the use of our net operating losses and certain other tax attributes in the future; (35) that our indebtedness could adversely affect our financial health and limit our ability to react to changes in our business and industry; (36) that we may require substantial capital to support business growth, and this capital may not be available to us on acceptable terms, or at all; (37) that our debt agreements include restrictive covenants, and failure to comply with these covenants could trigger acceleration of payment of outstanding indebtedness; (38) that we may reduce, or cease payment of, quarterly cash dividends; (39) that our stock price may be volatile; (40) that provisions of our certificate of incorporation, bylaws and other elements of our capital structure could limit our share price and delay a change of control of the company; and (41) that our bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ flexibility in obtaining a judicial forum for disputes with us or our directors, officers or employees. These risks and uncertainties, as well as other risks and uncertainties that could cause our actual results to differ significantly from management’s expectations, are not intended to represent a complete list of all risks and uncertainties inherent in our business, and should be read in conjunction with the more detailed cautionary statements and risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2015 and our Quarterly Report on Form 10-Q for the three months ended March 31, 2016.

Restructuring, acquisition and integration-related costs consist of costs related to the Company’s restructuring, acquisition and integration-related activities. Such costs include: 1) integration-related costs, such as system conversions and integration-related consulting and employee costs. The Company is also undertaking a long-term network optimization project designed to consolidate traffic onto network facilities operated by the Company and reduce the usage of other carriers’ networks. Integration-related costs associated with this initiative include costs to migrate traffic to lower cost circuits and to terminate existing contracts prior to their expiration; 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 business combinations, such as advisory, legal, accounting, valuation and other professional fees.

(2)On February 1, 2016, the Company sold certain assets related to its IT services product offerings. The primary purpose of the sale was to simplify operations and provide more flexibility to invest in new capabilities and services to drive growth in the Company’s core business. The purchase price in the transaction was $29.6 million, subject to post-closing contingencies that could increase or decrease the purchase price by up to $5.0 million. The Company received $26.6 million of cash upon completion of the sale. The other $3.0 million of consideration was deposited into an escrow account to fund potential indemnification obligations. The Company recognized a pretax gain of $6.3 million and recorded a $2.0 million deferred gain for contingent consideration. The carrying amount of the IT services assets was $17.5 million, which included $11.4 million of property and equipment, $2.3 million of goodwill, $3.5 million of other intangible assets and $0.3 million of other assets and liabilities.

Total revenue of the Company’s IT services business was $11.4 million during the three months ended September 30, 2015, of which $7.7 million was Enterprise/Mid-Market revenue and $3.7 million was Small Business revenue. There was no IT services revenue during the three months ended September 30, 2016. Total revenue of the Company’s IT services business was $34.9 million and $3.4 million during the nine months ended September 30, 2015 and 2016, respectively, of which $23.5 million and $2.3 million, respectively, was Enterprise/Mid-Market revenue and $11.4 million and $1.1 million, respectively, was Small Business revenue.

On July 15, 2016, the Company sold approximately 12,000 consumer customer relationships to one of its network providers for $3.8 million of cash and recognized a pretax gain of $2.8 million. The carrying amount of the disposed assets was $1.0 million.

(3)During the nine months ended September 30, 2015 and 2016, the Company redeemed and repurchased $126.1 million and $97.4 million, respectively, outstanding principal of its 8.875% Senior Notes due 2019 and recorded $9.7 million and $4.8 million, respectively, for losses on extinguishment of debt. The losses primarily consisted of premiums paid

on the Company’s debt repayments, the write-off of unamortized discount on debt and the write-off of unamortized debt issuance costs.

(4)In addition to our financial information presented in accordance with U.S. generally accepted accounting principles (“GAAP”), management uses certain “non-GAAP financial measures” within the meaning of the SEC Regulation G, to clarify and enhance understanding of past performance and prospects for the future. Generally, a non-GAAP financial measure is a numerical measure of a company’s operating performance, financial position or cash flows that excludes or includes amounts that are included in or excluded from the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP financial performance measures used by management are Adjusted EBITDA and Unlevered Free Cash Flow, as discussed below.

Management believes that these non-GAAP financial performance measures reflect our ongoing business in a manner that allows for meaningful comparisons and analysis of trends in our business, as they exclude the effect of non-operational items, such as restructuring, acquisition and integration-related costs, gain on sale of business and loss on extinguishment of debt and non-cash items, such as depreciation and amortization and stock-based compensation expense. Management believes that excluding the effects of certain non-operational and non-cash items enables investors to better understand and analyze the current period’s results and provides a better measure of comparability. Management also believes that these non-GAAP financial measures enable investors to evaluate our operating results and future prospects in the same manner as management. These non-GAAP financial measures may also facilitate comparing financial results across accounting periods and to those of peer companies.

There are limitations to using these non-GAAP financial performance measures. Adjusted EBITDA and Unlevered Free Cash Flow are not indicative of cash provided by or used in 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.

Adjusted EBITDA is defined as net income (loss) before interest expense and other, net, income tax provision (benefit), depreciation and amortization, stock-based compensation expense, impairment of goodwill and long-lived assets, restructuring, acquisition and integration-related costs, gain on sale of business and loss on extinguishment of debt. Management uses Adjusted EBITDA to evaluate the performance of our business and for strategic planning and forecasting. Adjusted EBITDA is also used in incentive compensation arrangements and is a factor in calculating debt covenants.

Unlevered Free Cash Flow is defined as net income (loss) before interest expense and other, net, income tax provision (benefit), depreciation and amortization, stock-based compensation expense, impairment of goodwill and long-lived assets, restructuring, acquisition and integration-related costs, gain on sale of business and loss on extinguishment of debt, less cash used for purchases of property and equipment. Unlevered Free Cash Flow is used by management to evaluate the performance of our business and to assess our ability to fund capital expenditures, make strategic acquisitions, service and repay debt and pay dividends.

(5)The Company reports segment information along the same lines that its Chief Operating Decision Maker reviews its operating results in assessing performance and allocating resources. The Company’s Chief Operating Decision Maker is its Chief Executive Officer. The Company’s reportable segments are strategic business units that are aligned around distinct customer categories to optimize operations. The Company operates the following four reportable segments:

·Enterprise/Mid-Market. The Company’s Enterprise/Mid-Market segment provides a broad range of data, voice and managed network services to distributed multi-site business customers.

·Small Business. The Company’s Small Business segment provides a broad range of data, voice and managed network services to small, often single-site business customers.

·Carrier/Transport. The Company’s Carrier/Transport segment provides transmission capacity and other data, voice and managed network services to telecommunications carriers and large enterprises.

·Consumer. The Company’s Consumer segment provides nationwide Internet access and related value-added services to residential customers.

The Company evaluates performance of its segments based on segment gross margin. Segment gross margin includes revenues from external customers and related cost of revenues. Costs excluded from segment gross margin include selling, general and administrative expenses, depreciation and amortization, impairment of goodwill and intangible assets, restructuring, acquisition and integration-related costs, gain on sale of business, interest expense and other, net, and loss on extinguishment of debt, as they are not considered in the measurement of segment performance.

(6)Represents full-time equivalents.

(7)Consumer 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)Consumer 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)Consumer 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.
