These forward-looking statements reflect, among other things, current expectations, plans, strategies, and anticipated financial results of the Consolidated Communications Holdings, Inc. (“Consolidated”) and FairPoint Communications, Inc. (“FairPoint”), both separately and as a combined entity. There are a number of risks, uncertainties, and conditions that may cause the actual results of Consolidated and FairPoint, both separately and as a combined entity, to differ materially from those expressed or implied by these forward-looking statements. These risks and uncertainties include the timing and ability to complete the proposed acquisition of FairPoint by Consolidated, the expected benefits of the integration of the two companies and successful integration of FairPoint’s operations with those of Consolidated and realization of the synergies from the integration, as well as a number of factors related to the respective businesses of Consolidated and FairPoint, including economic and financial market conditions generally and economic conditions in Consolidated’s and FairPoint’s service areas; various risks to stockholders of not receiving dividends and risks to Consolidated’s ability to pursue growth opportunities if Consolidated continues to pay dividends according to the current dividend policy; various risks to the price and volatility of Consolidated’s common stock; changes in the valuation of pension plan assets; the substantial amount of debt and Consolidated’s ability to repay or refinance it or incur additional debt in the future; Consolidated’s need for a significant amount of cash to service and repay the debt and to pay dividends on the common stock; restrictions contained in the debt agreements that limit the discretion of management in operating the business; legal or regulatory proceedings or other matters that impact the timing or ability to complete the acquisition as contemplated, regulatory changes, including changes to subsidies, rapid development and introduction of new technologies and intense competition in the telecommunications industry; risks associated with Consolidated’s possible pursuit of acquisitions; system failures; losses of large customers or government contracts; risks associated with the rights-of-way for the network; disruptions in the relationship with third party vendors; losses of key management personnel and the inability to attract and retain highly qualified management and personnel in the future; changes in the extensive governmental legislation and regulations governing telecommunications providers and the provision of telecommunications services; telecommunications carriers disputing and/or avoiding their obligations to pay network access charges for use of Consolidated’s and FairPoint’s network; high costs of regulatory compliance; the competitive impact of legislation and regulatory changes in the telecommunications industry; liability and compliance costs regarding environmental regulations; the possibility of disruption from the integration of the two companies making it more difficult to maintain business and operational relationships; the possibility that the acquisition is not consummated, including, but not limited to, due to the failure to satisfy the closing conditions; the possibility that the merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; and diversion of management’s attention from ongoing business operations and opportunities.
