BEVERLY, Mass., Nov. 05, 2025 (GLOBE NEWSWIRE) -- ATN International, Inc. ("ATN" or the "Company") (NASDAQ:ATNI), a leading provider of digital infrastructure and communications services, today reported financial results for the third quarter ended September 30, 2025.

Remarks by Brad Martin, ATN Chief Executive Officer

"Our third quarter results were in line with our expectations and demonstrated steady progress in executing our business transition plan and maintaining disciplined operational focus. We've been building positive momentum throughout the year, reflected in our year-over-year revenue and Adjusted EBITDA growth. Internationally, our network investments are driving growth in high-speed data and mobile data subscribers, and our focus on operational efficiency is expanding margins and strengthening cash flow. In the U.S., we're seeing tangible benefits from our investments in carrier and enterprise solutions, with new site activations from our carrier-managed services efforts and momentum in our fiber-fed deployments.

We're doing what we said we would do - methodically strengthening our operational foundation, improving our cost structure and margins, and positioning the business for sustainable growth as we move toward 2026."

Third Quarter 2025 Financial Results

Consolidated revenues were $183.2 million in the third quarter, up 3% versus $178.5 million in the year-ago quarter. This increase primarily reflects growth in fixed, carrier services, other, and construction revenue during the quarter that offset a year-over-year decline in mobility revenues.

Operating income was $9.8 million in the third quarter versus a loss of $(38.4) million in the year-ago quarter. The year-ago quarter included a $35.3 million goodwill impairment charge. A $5.1 million reduction in depreciation and amortization expenses, a $3.3 million reduction in transaction-related charges, and a $1.1 million reduction in the cost of services resulting from structural cost containment efforts, also contributed to the improvement.

Net Income attributable to ATN stockholders in the third quarter of 2025 was $4.3 million, or $0.18 per diluted share, versus a net loss of $(32.7) million, or $(2.26) per diluted share, in the year-ago quarter.

Adjusted EBITDA¹ was $49.9 million in the third quarter of 2025, up 9% from $45.7 million in the year-ago quarter.

2025 Business Outlook

"As we enter the final quarter of the year, we're encouraged by the steady momentum across our business segments and remain focused on disciplined execution of our strategic roadmap," said Martin. "We're seeing revenue growth in our domestic operations, led by the expansion of carrier-managed services and targeted enterprise sales execution, which reinforces our confidence in the strategic direction we've set. Internationally, we're beginning to see stabilization in mobility trends and improving operational metrics in our core markets.

"Our operational efficiency initiatives continue to generate measurable results, with disciplined cost management and optimized capital allocation keeping us well-positioned to deliver on our full-year objectives. With three quarters of solid execution behind us, we are refining our Adjusted EBITDA outlook and reaffirming our guidance for revenue, capital expenditure, and Net Debt Ratio. We remain confident in our ability to generate sustainable, long-term value creation for our shareholders."

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 reconciliation 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.

Cautionary Language Concerning Forward-Looking Statements

This press release contains forward-looking statements relating to, among other matters, the Company's future financial performance, business goals and objectives, and results of operations, its future revenues, operating income, cash flows, network and operating costs, Adjusted EBITDA, Net Debt Ratio, and capital investments; the Company's liquidity; receipt of certain government grants and management's plans and strategy for the future. These forward-looking statements are based on estimates, projections, beliefs, and assumptions and are not guarantees of future events or results.
