ATN Reports Fourth Quarter and Full Year 2021 Results and Provides Financial Outlook

Fourth Quarter 2021 Results

Beverly, MA (February 23, 2022) -- ATN International, Inc. (“ATN” or the “Company”) (Nasdaq: ATNI), a leading provider of digital infrastructure and communications services, today reported results for the fourth quarter and year ended December 31, 2021.

“We delivered a strong quarter marked by execution on strategic objectives aligned with our long-term growth plans,” said Michael Prior, Chief Executive Officer of ATN. “Notably, we completed the integration of Alaska Communications, brought digital connectivity to remote areas such as southwestern Alaska and northern Arizona, and made important advances in our domestic fiber-first platform strategy. With the contribution of Alaska Communications, we achieved more than 50% topline growth year over year as well as a more balanced revenue contribution between our domestic and international segments. At the same time, we made key investments in foundational infrastructure across our operating areas for future expansion while bolstering our leadership in both growing and mature markets.

² See Table 5 for reconciliation of Operating Income to Adjusted EBITDA, a non-GAAP measure.

“Our expansion in Alaska drove momentum in our U.S. operations, led by business and wholesale customers, including national wireless carriers. We see ample opportunity to accelerate our revenue and customer growth by further expanding the reach of our domestic data networks. In addition to increasing our coverage, we are investing in our offerings of higher-speed services through fiber and other high-speed data solutions. This also includes fiber and other infrastructure builds for our carrier services customers as we continue to transition away from our legacy wholesale wireless services to a more durable ‘glass and steel’ fiber-first model.

“Our international operations remained resilient with double-digit year-over-year mobility and carrier services revenue growth. In addition, our broadband subscriber levels continued to show strength with year-over-year growth and low churn. Our strategic decision to increase our investments in marketing and network resources resulted in heightened operating expense levels for this segment in the quarter. By maintaining our leadership in mature markets through strong services and continued speed improvements, we are generating steady cash flows and using these proceeds to invest in higher-growth markets, such as Guyana, where we are rapidly expanding the reach and capabilities of our high-speed fixed and mobile networks,” added Prior.

Fourth Quarter 2021 Financial Results

Fourth quarter 2021 consolidated revenues were $187.6 million, up 52% compared with $123.7 million in the same period a year ago. The Company reported an operating loss of $20.3 million and Adjusted EBITDA² of $42.3 million compared with an operating loss of $14.7 million and Adjusted EBITDA² of $30.5 million in the same period a year ago. The increase in revenue and Adjusted EBITDA² was mostly driven by the addition of Alaska Communications' results. The higher operating loss for the quarter was mainly driven by lower profitability in our legacy US Telecom business in addition to the reduction of high-cost support subsidies in our International Telecom business. Net loss attributable to ATN stockholders for the fourth quarter was $24.2 million, or $1.60 per share, compared with net loss attributable to ATN stockholders of $20.5 million, or $1.29 per share, in the same period a year ago.

Fourth Quarter 2021 Operating Segment Results

The Company recorded financial results during the fourth quarter of 2021 in three categories: (i) International Telecom; (ii) US Telecom; and (iii) All Other. For the purposes of the below presentation, the Company’s Renewable Energy segment has been combined with the Company’s Corporate segment and Other segment as “All Other.”

Operating Results (in Thousands)

*For this table presentation, the Renewable Energy segment results and Corporate and Other segment results were combined. See table 4 for the separate presentation of the financial performance of these segments.

**Includes capital expenditures reimbursable from customers of $1.0 and $9.7 million for the three and twelve months ended December 31, 2021, respectively, and $13.1 and $15.0 million for the three and twelve months ended December 31, 2020, respectively.

International Telecom

International Telecom revenues³ were $87.5 million for the quarter, up 4% year over year. This increase was mainly due to mobility subscriber growth as well as higher carrier services revenue, partially offset by a decline in managed services revenue and in federal high-cost support subsidies for the U.S. Virgin Islands. Increased travel and tourism in the U.S. Virgin Islands drove the increase in higher carrier service revenues. Operating expenses increased in most markets incrementally compared with the prior year as operations returned to pre-pandemic levels and the Company worked to expand its subscriber base in these markets. The combination of higher operating expenditures and a one-time impairment charge of $20.6 million for our operations in the U.S. Virgin Islands, contributed to a quarterly operating loss of $7.1 million and Adjusted EBITDA² of $27.9 million, compared with an operating income of $14.8 million and Adjusted EBITDA² of $29.0 million in the same period a year ago.

US Telecom

US Telecom segment revenues⁴ were $100.1 million in the quarter, up from $38.7 million in the prior year period. Business and carrier services revenues accounted for approximately 75% of the segment’s service revenues in the fourth quarter of 2021. Operating loss was $3.1 million compared with an operating income of $1.8 million in the same period a year ago. This decrease in operating income was mainly due to lower profitability in our legacy US Telecom business and higher acquisition costs and acquisition-related amortization expenses from Alaska Communications. Adjusted EBITDA² for the quarter was $22.3 million compared with $7.8 million in the same period a year ago. The increase in segment revenue and Adjusted EBITDA² was mainly due to the Company’s successful consolidation of Alaska Communications, partially offset by the year-over-year increases in network costs for additional FirstNet sites and expenses for the Company’s private network operations.

By the end of the fourth quarter of 2021, the Company had completed and activated approximately 60% of the total sites related to the network build portion of its long-term FirstNet Agreement. The completion of sites was slightly slower than expected due to delays relating to supply chain and the continuation of the pandemic. The Company expects to complete an additional 30% of the total build by the end of 2022 and that revenues from the build will be largely offset by construction costs incurred in the same period.

³ International Telecom revenues are generated by delivery of a broad range of communications and managed IT services, including data, voice and video services from the Company’s fixed and mobile network operations in Bermuda and the Caribbean, and include direct government payments as part of the FCC high-cost support program in the USVI.

⁴ US Telecom revenues consist of broadband, carrier services, managed IT services, fixed enterprise, and mobile retail revenues from the Company’s networks and operations in Alaska and in the western United States, including various government programs such as CAF II, E-Rate, Lifeline and rural healthcare support programs.

Balance Sheet and Cash Flow Highlights

As of December 31, 2021, the Company had total cash, cash equivalents and restricted cash of $80.7 million compared with $105.0 million as of December 31, 2020. On July 22, 2021, the Company completed the acquisition of Alaska Communications for approximately $339.5 million. The acquisition was funded through cash on hand, a draw under the Company’s existing revolving credit facility, an equity contribution from the Company’s financial partner, and proceeds from Alaska Communications’ new credit agreement that is non-recourse to the Company. At the end of the quarter, the Company had $61.5 million drawn under its $200.0 million revolving facility, and Alaska Communications had a $210.0 million term loan facility outstanding and $2.0 million drawn under its $35.0 million revolving facility.

Net cash provided by operating activities was $80.5 million for the year ended December 31, 2021, compared with $86.3 million for the year ended December 31, 2020. The year-over-year decline in operating cash flow was mostly due to the increase in operating loss for the full year of 2021 and an increase of $33.0 million in the FirstNet construction customer receivable, which was partially offset by lower working capital balances. For the year ended December 31, 2021, the Company used net cash of $104.8 million for investing and financing activities compared to $143.6 million for the year ended December 31, 2020. The net use of cash was primarily attributable to the $339.5 million purchase price of Alaska Communications, $106.1 million in capital expenditures, $13.3 million of purchases of minority equity interests in the Company’s subsidiaries, $21.4 million in repurchases of Company common stock and dividends to Company stockholders, and $7.5 million in minority partner distributions. These uses of cash were partially offset by net borrowings of $285.0 million and $71.5 million of partner equity contributions to purchase Alaska Communications, $7.5 million in new government grant funding received, $18.6 million in net proceeds received from the completion of the Vibrant Energy equity sale and $35.5 million in net new borrowings under the FirstNet receivables credit facility.

Stock Buybacks and Quarterly Dividends

On December 13, 2021, ATN announced that its Board of Directors had declared a quarterly dividend of $0.17 per share, payable on January 7, 2022, on all common shares outstanding to stockholders of record as of December 31, 2021. For the full year, ATN paid $0.68 per share in dividends. ATN utilized cash from its balance sheet to repurchase $5.7 million in common stock in the fourth quarter of 2021 and $10.5 million in common stock in the full year of 2021.

Business Outlook

“Looking forward, we plan to fully leverage our differentiated approach to connect more people around the world,” Prior continued. “This will include an increased level of investment in our fiber networks and other digital infrastructure across our U.S. and international markets. As a result of these investments, we anticipate additional revenue growth opportunities, higher customer counts and strong market share. We now cover nearly half a million homes with our broadband networks, and we expect that metric, along with the percentage of our customers utilizing fiber and other higher-speed data solutions, to increase as we target what we see as rapidly growing demand. High-speed connectivity has become essential for all communities and businesses. As we focus on meeting this demand, we are providing investors with additional operating metrics on homes passed and customer connections and anticipate updating this information in future quarters.

“Additionally, we are providing the following full-year 2022 guidance and three-year outlook to give investors a better sense of the evolution and potential of our business. These forecasts take into account the current state of our domestic and international markets as well as certain strategic initiatives. From a broad perspective, our goal as an organization is to continue leaning into servicing remote and rural markets to better satisfy the growing demand for enhanced digital infrastructure around the world. We have confidence in our strategy and team to execute on these plans going forward, and in our ability to accelerate our business momentum and deliver enhanced shareholder value,” Mr. Prior noted.

Three Year Outlook

The Company has set the following targets for its business to be achieved in 2024. These goals are largely based on, and in line with, the Company’s continuing investments in its “fiber-first” platform strategy. The three-year targets are as follows:

Upon completion of this three-year plan, and possibly sooner, the Company believes it will be in a position to use its business momentum and growing operating cash flow to return more value to shareholders through increased dividends or other means.
