ATN International, Inc. Reports Second Quarter 2026 Results; Announces Increased Repurchase Authorization; and Reaffirms 2026 Outlook

Delivers year-over-year revenue growth of 2% and Adjusted EBITDA1 growth of 9%

Receives $268 million in cash at the initial closing of the US Tower Portfolio Sale4

Increases share repurchase authorization to $30 million

BEVERLY, Mass., Aug. 05, 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 second quarter ended June 30, 2026. ATN’s management will host a conference call and webcast tomorrow, August 6, 2026, beginning at 11:00 a.m. Eastern Time to review these results.

“Our second quarter results demonstrate the continued strength and resilience of our business. We delivered growth in both total revenue and Adjusted EBITDA, with profitability outpacing sales growth, reflecting improving operating leverage,” said Naji Khoury, ATN’s Chief Executive Officer. “In my first several months, I have had the opportunity to visit our markets, meet with team members, customers, stakeholders, and investors, and spend meaningful time understanding the strength of our platform. We have experienced management teams, capable operating organizations, strong infrastructure assets and customer relationships that have been built over many years, which provide a solid foundation to further optimize our operations.”

Mr. Khoury added, “During the quarter, we completed the initial closing of the sale of our US tower portfolio and entered into an agreement to sell certain US spectrum licenses, demonstrating our ability to unlock value from our infrastructure assets as the tower transaction multiple far exceeded our current trading multiple. Additionally, in June our Board increased both the quarterly cash dividend, and the Company’s share repurchase authorization, reflecting our confidence in the outlook for the business, the strength of our financial position, and our commitment to disciplined capital allocation to create long-term shareholder value.”

Second Quarter 2026 Operating and Financial Highlights (as compared to the Second Quarter 2025)

• High-speed broadband homes passed expanded by 21% to 523,400, supported by fixed wireless deployments in the second half of 2025
• Total high-speed broadband customers grew 1% to 140,900
• Revenue increased 2% to $184.5 million, driven by growth in both the International and US Telecom segments
• Operating income increased to $239.7 million, primarily due to a $229.9 million gain from the initial closing of the US Tower Portfolio Sale4
• Net cash provided by operating activities decreased 11% to $53.5 million, reflecting movements in operating cash related to the US Tower Portfolio sale4
• Adjusted EBITDA1 increased $4.0 million, or 9%, to $49.7 million and Adjusted EBITDA Margin1 improved from 25.3% to 27.0%
• Net Debt Ratio3 improved to 0.91x from 2.36x on December 31, 2025
  
  

Second Quarter 2026 Financial Results (as compared to the second quarter 2025)

Consolidated revenues were $184.5 million, up $3.2 million, or 2% versus $181.3 million. The increase was primarily driven by carrier services revenues and market demand for fixed and other ancillary services, which offset year-over-year declines in fixed consumer revenues primarily related to the previously disclosed loss of a government subsidy, and lower construction revenues.

Operating income was $239.7 million versus $0.2 million in the year-ago quarter. The increase reflects a $229.9 million gain recorded on the initial closing of the US Tower Portfolio Sale4, and the above-mentioned revenue growth as well as lower restructuring and reorganization and depreciation and amortization expenses.

Net income attributable to ATN stockholders was $167.3 million, or $10.71 per diluted share, versus a net loss of $(7.0) million, or $(0.56) per share.

Adjusted EBITDA1 was $49.7 million, up $4.0 million, or 9%, from $45.8 million in the year-ago quarter and Adjusted EBITDA Margin1 expanded to 27.0% from 25.3%. The increase was primarily driven by higher revenues and cost efficiencies.

US Tower Portfolio Sale4

On June 2, 2026, the Company completed the initial closing of the sale of its southwestern US tower portfolio (the “US Tower Portfolio Sale”)4 to an affiliate of Everest Infrastructure Partners, Inc. and received $267.7 million in cash. The Company may receive up to an additional $29.6 million in cash consideration at subsequent closings expected to occur over the next ten months subject to the satisfaction or waiver of specified construction and operational conditions related to tower sites deferred at the initial closing.

2026 Full-Year Outlook:

The Company reaffirms its previously updated financial outlook for full-year 2026, reflecting the impact of the initial closing of the US Tower Portfolio Sale4, as follows:

• Adjusted EBITDA2 is expected to be in the range of $183 million to $193 million
• 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, Adjusted EBITDA Margin, 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, the loss on dispositions, transfers and contingent consideration, and non-cash stock-based compensation.

Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by total revenue.

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 guidance for the full-year 2026 excludes potential charges or gains that may be recorded during the fiscal year, including among other things, 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.

Cautionary Language Concerning Forward-Looking Statements

These and other additional factors that may cause actual future events and results to differ materially from the events and results indicated in the forward-looking statements above are set forth more fully under Item 1A “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission (“SEC”) on March 16, 2026, and the other reports the Company files from time to time with the SEC.
