Alaska Communications Reports Third Quarter 2020 Results

ANCHORAGE, Alaska, November 4, 2020 -- Alaska Communications Systems Group, Inc. (NASDAQ: ALSK) today reported financial results for the third quarter of 2020.

“Our results for the third quarter reflect execution of our strategic initiatives to deliver industry-leading telecommunications products and services. Prioritizing superior customer service and fiber-based network solutions, we have established Alaska Communications as a premier provider. We continue to strengthen our fiber infrastructure, to facilitate our multiyear transition to IP-based services, and to evaluate means to increase our access and core network. This includes optical transport network upgrades to our subsea Northstar fiber resulting in a capacity increase of over five times, as well as securing CBRS spectrum in 135 cities ranging from southeast Alaska to the North Slope. Our biggest strengths in 2020 have been to manage the unexpected, quickly offer customers solutions, and continue to drive ahead adding many route miles of fiber. In addition to benefiting our customers, we are creating opportunities.

“Also, after years in development, in October, we went live with our new business and operating systems that will enhance the customer experience through streamlined ordering process; improve business analytics and reporting; and simplify operations that we expect to yield expense savings and drive operational excellence in coming years. We are committed to connecting the people and businesses of Alaska and beyond, investing in our future and driving growth to benefit our constituents. We are very excited about the future,” said Bill Bishop, president & CEO.

“We continue to grow total revenue, increasing 2.3% for the quarter, year over year. Business and Wholesale revenue grew 5.6%, compared to 2019, and we expanded our Adjusted EBITDA margin to 27.5% in third quarter 2020, up from 26.7% in third quarter 2019. As the new work environment has altered business requirements, customers are both modifying and accelerating their network plans. During the quarter, demand for equipment and managed IT services increased, which led to a net 27.4% increase in revenue, compared to the same period last year. Our results this quarter reflect our strategic plan for growth, and we expect to be at the high end of our guidance for 2020,” said Laurie Butcher, Chief Financial Officer.

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 $12.4 million in the nine-month period of 2020).
