ANCHORAGE, Alaska--(BUSINESS WIRE)--March 15, 2021--Alaska Communications Systems Group, Inc. (NASDAQ: ALSK) today reported financial results for the fourth quarter and year ended December 31, 2020.

“We are pleased with our strong financial performance for 2020, driven by broadband growth and increased customer cloud infrastructure during this unprecedented year. We are proud of our team and their continued exemplary customer service to our communities, particularly the education and healthcare areas. During 2020, we continued to invest in our network and expanded our broadband service by more than 3,700 locations in underserved areas of Alaska, an increase in locations of approximately 33%. In addition, we began mesh fixed wireless trials, offering internet speeds up to 1 Gig. In 2021, we plan to expand our mesh network as part of our strategy to upgrade one third of our network, extending our reach to approximately 42,000 new and existing customer locations with new or improved service.

“On March 12, 2021, our shareholders approved our merger with a subsidiary of ATN International, Inc. This transaction positions us to remain the premier communications partner within the state of Alaska, while providing significant opportunities to grow. We expect synergies in fiber infrastructure expansion and in the latest technologies for commercial customers, including next-generation managed services and private network solutions,” said Bill Bishop, President & CEO.

Laurie Butcher, Alaska Communications Chief Financial Officer, said, “In 2020, we delivered strong financial performance even with the impact of the COVID-19 pandemic. We exceeded revenue guidance, driven by increased broadband revenue, equipment sales and special project revenue coming online. Our business and wholesale growth offset our consumer and regulatory decreases, and our growth revenues continue to outpace our legacy declines. Regarding capex, due to the timing of certain projects, we were able to accelerate expansion of our fiber network and spent slightly more than guidance. Adjusted Free Cash Flow was on target, and even with incurring $7.2 million in payments associated with transaction costs in the fourth quarter, our cash balances remain strong. As a result, we are well positioned for 2021.”

Non-GAAP Measures

In an effort to provide investors with additional information regarding our financial results, we have provided certain non-GAAP financial information, including Adjusted EBITDA, Adjusted Free Cash Flow and Net Debt. Adjusted EBITDA eliminates the effects of period to period changes in costs that are not directly attributable to the underlying performance of the Company’s business operations and is used by Management and the Company’s Board of Directors to evaluate current operating financial performance, analyze and evaluate strategic and operational decisions and better evaluate comparability between periods. Adjusted Free Cash Flow is a non-GAAP liquidity measured used by Management and the Company’s Board of Directors to assess the Company’s ability to generate cash and plan for future operating and capital actions. Adjusted EBITDA and Adjusted Free Cash Flow are common measures utilized by our peers (other telecommunications companies) and we believe they provide useful information to investors and analysts about the Company’s operating results, financial condition and cash flows. Net Debt provides Management and the Company’s Board of Directors with a measure of the Company’s current leverage position. The definition and computation of these non-GAAP measures are provided on Schedules 4, 6 and 9 to this press release. Adjusted EBITDA and Adjusted Free Cash Flow should not be considered a substitute for Net Income, Net Cash Provided by Operating Activities and other measures of financial performance recorded in accordance with GAAP. Reconciliations of our non-GAAP measures to our nearest GAAP measures can be found in the tables in this release. Other companies may not calculate non-GAAP measures in the same manner as Alaska Communications. The Company does not provide reconciliations of guidance for Adjusted EBITDA to Net Income, and Adjusted Free Cash Flow to Net Cash from Operating Activities, in reliance on the unreasonable efforts exception provided under Item 10(e)(1)(i)(B) of Regulation S-K. The Company does not forecast certain items required to develop the comparable GAAP financial measures. These items are charges and benefits for uncollectible accounts, certain other non-cash expenses, unusual items typically excluded from Adjusted EBITDA and Adjusted Free Cash Flow, and changes in operating assets and liabilities (generally the most significant of these items, representing cash inflows of $15.9 million in the twelve-month period of 2020).

Forward-Looking Statements

This press release includes certain "forward-looking statements," as that term is defined in the Private Securities Litigation Reform Act of 1995.

Non-GAAP Measures:

The Company provides certain non-GAAP financial information, including Adjusted EBITDA, Adjusted Free Cash Flow and Net Debt. Adjusted EBITDA eliminates the effects of period to period changes in costs that are not directly attributable to the underlying performance of the Company’s business operations and is used by Management and the Company’s Board of Directors to evaluate current operating financial performance, analyze and evaluate strategic and operational decisions and better evaluate comparability between periods. Adjusted Free Cash Flow is a non-GAAP liquidity measure used by Management to assess the Company’s ability to generate cash and plan for future operating and capital actions. Adjusted EBITDA and Adjusted Free Cash Flow are common measures utilized by our peers (other telecommunications companies) and we believe they provide useful information to investors and analysts about the Company’s operating results, financial condition and cash flows. Net Debt provides Management and the Board of Directors with a measure of the Company’s current leverage position.

The Company does not provide reconciliations of guidance for Adjusted EBITDA to Net Income, and Adjusted Free Cash Flow to Net Cash Provided by Operating Activities, in reliance on the unreasonable efforts exception provided under Item 10(e)(1)(i)(B) of Regulation S-K. The Company does not forecast certain items required to develop the comparable GAAP financial measures. These items are charges and benefits for uncollectible accounts, certain other non-cash expenses, unusual items typically excluded from Adjusted EBITDA and Adjusted Free Cash Flow, and changes in operating assets and liabilities (generally the most significant of these items, representing cash inflows of $15.9 million in the twelve-month period ended December 31, 2020).

Adjusted EBITDA and Adjusted Free Cash Flow are not GAAP measures and should not be considered a substitute for net income, net cash provided by operating activities, or net cash provided or used. Adjusted EBITDA as computed above is not consistent with the definition of Consolidated EBITDA referenced in our 2019 Senior Credit Facility, and other companies may not calculate Non-GAAP measures in the same manner we do.

Adjusted EBITDA is defined as net income before interest expense and income, loss on extinguishment of debt, depreciation and amortization, other income and expense, gain or loss on asset purchases or disposals, provision for income taxes, stock-based compensation, transaction-related costs, cash severance expense, and net loss attributable to noncontrolling interest.

* Quarterly Adjusted Free Cash Flow fluctuates and should not be viewed as an indicator of annual performance. Onetime events, seasonality of capital spend and the timing of interest payments may result in negative Adjusted Free Cash Flow in one or more quarters.

Non-GAAP Measures:

Adjusted Free Cash Flow is a non-GAAP liquidity measure and is defined as Adjusted EBITDA, less recurring operating cash requirements which include capital expenditures, cash income taxes refunded or paid, cash interest paid, amortization of GCI capacity revenue, cash severance expense for the Company's former Chief Executive Officer, and cash receipts and payments, deferred costs and amortized revenue and expense associated with certain prefunded special projects as defined in the 2019 Senior Credit Facility. Amortization of deferred revenue associated with our interconnection agreement with GCI is excluded from Adjusted Free Cash Flow because no cash was received by the Company in connection with this agreement. Amortization of all other deferred revenue, including that associated with other IRU capacity arrangements, is included in Adjusted Free Cash Flow because cash was received by the Company, typically at contract inception, and is being recognized as revenue over the term of the relevant agreement.

See Schedule 3 for Net cash provided by operating activities, Net cash used by investing activities, and Net cash used by financing activities.

See Schedule 5 for the reconciliation of net cash provided by operating activities to Adjusted Free Cash Flow.
