Delivers year-over-year increases in revenue, operating income and Adjusted EBITDA¹

Initial closing of the U.S. tower portfolio sale remains on track for Q2 2026

BEVERLY, Mass., May 06, 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 first quarter ended March 31, 2026. ATN’s management will host a conference call and webcast tomorrow, May 7, 2026, beginning at 10:00 a.m. Eastern time to review these results.

“As I step into this role, my priority is translating ATN’s foundational capabilities into the next stage of value creation. In my early weeks, I have been actively engaging across our operations and working closely with our leadership teams to assess the business and identify opportunities for simplification and optimization, while maintaining a disciplined approach to capital allocation,” said Naji Khoury, ATN’s Chief Executive Officer.

Mr. Khoury concluded, “I’m confident that my deep telecommunications industry experience, with a strong focus on operational and strategic execution, positions us well to build on the progress and momentum reached in the second half of 2025 and into the first quarter of 2026.”

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

• High-speed broadband homes passed of 523,300 expanded by 24% supported by fixed wireless deployments in late 2025
• Total high-speed broadband subscribers grew 3% to 142,500
• Revenue increased 2% to $182 million, driven by modest growth in both the international and US segments
• Operating income increased $9.0 million to $11.7 million, driven primarily by higher revenue, cost containment efforts, and lower depreciation and amortization
• Net cash provided by operating activities decreased $6.1 million, or 17%, to $29.8 million, reflecting increased working capital requirements largely due to the timing of government payments
• Adjusted EBITDA¹ increased $4.3 million, or 10%, to $48.6 million
• Net Debt Ratio³ improved to 2.30x from 2.52x
  
  

“Our first-quarter results reflect solid performance across our business,” said ATN’s Chief Financial Officer, Carlos Doglioli. “The team delivered year-over-year increases in total revenue, operating income and Adjusted EBITDA, reflecting steady execution across the entire organization. Revenue increased in both our international and US segments, driven by high-value subscriber growth as well as increased carrier services and ancillary products revenues, which offset expected declines in legacy revenue streams and the loss of US government high-cost support subsidy in one of our markets.”

Mr. Doglioli added, “We continue to benefit from our cost containment initiatives, which, combined with top-line growth, supported improved profitability and margin expansion during the quarter. We remain focused on our financial priorities, including margin improvement, cash flow expansion, and further strengthening the balance sheet.”  

First Quarter 2026 Financial Results

Consolidated revenues were $182.2 million, up $2.9 million, or 1.6% versus $179.3 million in the year-ago quarter. The increase was primarily driven by carrier services revenues, which were up $3.0 million, or 8.9% year-over year, reflecting an increase in the number of completed sites in the US segment and market demand in both the international and US segments. Additionally, ancillary service revenues in our international segment were up $1.7 million, or 54.3% year-over-year.

Operating income was $11.7 million, an increase of $9.0 million from the year-ago quarter. The improvement reflects the above-mentioned revenue growth, combined with lower cost of services resulting from our cost containment efforts and lower depreciation and amortization expenses.

Net loss attributable to ATN stockholders was $(2.8) million, or $(0.29) per share, versus a net loss of $(8.9) million, or $(0.69) per share, in the year-ago quarter.

Adjusted EBITDA¹ was $48.6 million, up $4.3 million, or 10%, from $44.3 million in the year-ago quarter and the Adjusted EBITDA Margin¹ expanded from 24.7% to 26.7% in the first quarter. The increase was primarily driven by higher revenues and lower costs.

US Tower Portfolio Sale Update⁴

The Company continues to expect the initial closing of the pending US tower portfolio sale to occur in the second quarter of 2026 (the “Initial Closing”) generating gross proceeds of approximately $250 to $270 million. Subsequent closings, totaling approximately $27 to $47 million, are anticipated to occur over the twelve months following the Initial Closing, subject to the achievement of specified construction and operational milestones at designated sites within the tower portfolio.

2026 Full-Year Outlook:

The Company reaffirms its previously announced financial outlook for full-year 2026 as follows:

• Adjusted EBITDA² expected to be in the range of $190 to $200 million, excluding the impact of the pending US tower portfolio sale⁴
• The initial closing of the US tower portfolio sale⁴ is expected to occur in the second quarter of 2026, which we expect will reduce our 2026 Adjusted EBITDA² outlook by $6 million to $8 million
• Capital expenditures are expected to be in the range of $105 to $115 million (net of reimbursable expenditures)
  
  

ATN intends to reassess and update its 2026 full-year outlook as appropriate after the initial closing of the US tower portfolio sale⁴.

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 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.
