Earnings Conference Call
Thursday, March 5, 2026, at 10:00 a.m. ET; web participant link: https://edge.media-server.com/mmc/p/2kqggmh2

BEVERLY, Mass., March 04, 2026 (GLOBE NEWSWIRE) -- ATN International, Inc. (“ATN”, the “Company”, “we”, “us”, and “our”) (Nasdaq: ATNI), a leading provider of digital infrastructure and communications services, today reported financial results for the fourth quarter and full year ended December 31, 2025.

Remarks by Brad Martin, ATN Chief Executive Officer
"Our fourth quarter performance capped a year of steady operational progress and strengthening financial performance at ATN,” said Brad Martin, ATN’s Chief Executive Officer. “During the quarter, we delivered growth in both revenue and Adjusted EBITDA, expanded our high-speed subscriber base, and significantly increased high-speed broadband homes passed through a major fixed wireless deployment in Alaska, creating a meaningful runway for future subscriber growth. At the same time, we tightened our cost structure, reinforcing our focus on operating efficiency and sustainable profitability. For the full year, that execution translated into higher operating profitability, stronger cash generation, and a business that is better aligned with our strategic focus on mobile, high-speed data and differentiated carrier solutions.

“Throughout 2025, we remained focused on strengthening our competitive position in our international markets by growing our mobility and high-speed subscriber bases, while leveraging government-funded and, to a lesser extent, internally allocated capital, to expand our US infrastructure. At the same time, we optimized our operations to drive future margin improvement,” Martin continued. “As capital intensity has moderated following our peak organic investment cycle, we have generated increased cash flow from operations and strengthened our balance sheet. We are entering 2026 from a position of greater resilience and flexibility, supported by operational improvements and the pending sale of our US tower portfolio, with a clear focus on our strategic objectives.”

Fourth Quarter and Full Year 2025 Financial Results

Consolidated revenues were $184.2 million in the fourth quarter, up 2% versus $180.5 million in the year-ago quarter. Excluding construction and other revenues, communication service revenues increased 3% year-over year reflecting growth in mobility, fixed, carrier services revenues. Full-year consolidated revenues for 2025 were essentially flat year-over-year at $728.0 million. Excluding construction and other revenues, communication service revenues declined 1% as growth in carrier services was more than offset by declines in mobility and fixed revenues.

Operating income was $15.7 million in the fourth quarter, increasing $7.0 million from the year-ago quarter. The improvement reflects a gain on spectrum asset dispositions as well as structural cost containment efforts which contributed to reductions in selling, general and administrative costs. Full-year operating income for 2025 was $28.4 million versus a full-year operating loss of $(0.8) million in the prior year, which included the 2024 goodwill impairment charge of $35.3 million.

Net Loss attributable to ATN stockholders in the fourth quarter of 2025 was $(3.3) million, or $(0.32) per share, versus net income of $3.6 million, or $0.14 per diluted share, in the year-ago quarter, which reflected an $8.9 million tax benefit. The fourth quarter of 2025 includes a $5.3 million expense for the write down of an equity investment. Full year 2025 net loss was $(14.9) million, or $(1.38) per share, compared with a net loss of $(26.4) million, or $(2.10) per share last year, which included the above referenced 2024 goodwill impairment charge and tax benefit.

Adjusted EBITDA¹ was $50.0 million in the fourth quarter of 2025, up 8% from $46.2 million in the year-ago quarter. Full-year 2025 Adjusted EBITDA¹ increased 3% to $190.0 million, from the prior-year result of $184.1 million.

2026 Business Outlook

“As we look to 2026, our priority is to convert the investments we have made over the past several years into sustained cash generation and margin expansion,” said Martin. “We are entering the year with positive business momentum, a more efficient operating model, and disciplined capital allocation, leveraging government funding to support network growth and enhance returns. Together, these elements give us confidence in our ability to deliver further progress in 2026.”

Martin continued, “The pending sale of our US tower portfolio and the completion of the spectrum asset sales in the fourth quarter represent strategic actions to unlock asset value and further strengthen our balance sheet through debt reduction. With a renewed focus on our mobility, core broadband and carrier businesses, and continued discipline in new investments, we expect to further increase our financial flexibility and enhance our capacity to pursue attractive growth opportunities. Combined with encouraging trends in both our international markets and our US carrier and enterprise solutions in the second half of 2025, these actions position ATN well as we move into 2026 and beyond.”

• ATN expects Adjusted EBITDA² to be in the range of $190 to $200 million, excluding the impact of the pending US tower portfolio sale⁴

• Capital expenditures are expected to be in the range of $105 to $115 million (net of reimbursable expenditures)

Use of Non-GAAP Financial Measures and Definition of Terms

In addition to financial measures prepared in accordance with generally accepted accounting principles (“GAAP”), this press release also contains non-GAAP financial measures. Specifically, the Company has included EBITDA, Adjusted EBITDA, Net Debt, and Net Debt Ratio in this release and the tables included herein.

EBITDA is defined as Operating income (loss) before depreciation and amortization expense.

Adjusted EBITDA is defined as Operating income (loss) before depreciation and amortization expense, transaction-related charges, restructuring and reorganization expenses, one-time impairment or special charges, the gain (loss) on dispositions, transfers and contingent consideration, and non-cash stock-based compensation.

Net Debt is defined as total debt less cash and cash equivalents and restricted cash.

Net Debt Ratio is defined as Net Debt divided by the trailing four quarters ended total Adjusted EBITDA at the measurement date.

The Company believes that the inclusion of these non-GAAP financial measures helps investors gain a meaningful understanding of the Company's core operating results and enhances the usefulness of comparing such performance with prior periods. Management uses these non-GAAP measures, in addition to GAAP financial measures, as the basis for measuring the Company’s core operating performance and comparing such performance to that of prior periods. The non-GAAP financial measures included in this press release are not meant to be considered superior to or a substitute for results of operations prepared in accordance with GAAP and should be used supplementally to the Company’s GAAP financial results. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are set forth in the text of, and the accompanying tables to, this press release. While non-GAAP financial measures are an important tool for financial and operational decision-making and for evaluating the Company’s own operating results over different periods of time, the Company urges investors to review the reconciliations of these financial measures to the comparable GAAP financial measures included below, and not to rely on any single financial measure to evaluate its business. Additionally, these non-GAAP financial measures may not be calculated in the same manner as similar measures presented by other companies.

In addition, the forward-looking Adjusted EBITDA for the full year 2026 excludes potential charges or gains that may be recorded during the fiscal year, including among other things such as restructuring and reorganization expenses, transaction-related expenses and gains or losses on dispositions, transfers and contingent consideration. The Company has not attempted to provide reconciliations of such forward-looking non-GAAP earnings guidance to the comparable GAAP measure, as permitted by Item 10(e)(1)(i)(B) of Regulation S-K, because of the impact and timing of these potential charges or gains is inherently uncertain and difficult to predict and is unavailable without reasonable efforts. In addition, the Company believes such reconciliations would imply a degree of precision and certainty that could be confusing to investors. Such items could have a substantial impact on GAAP measures of the Company’s financial performance.
