ATN International, Inc. is a Delaware-based provider of digital infrastructure and communications services focused on rural and remote markets in the US, Alaska, Bermuda, the Caribbean, Cayman Islands and Guyana. It operates through two main segments: US Telecom and International Telecom, offering fixed broadband, carrier, mobility and managed services.

The company emphasizes long-lived fiber and tower assets, recurring carrier contracts, and government-supported programs such as USF, Rural Health Care, E-rate and a large FCC Replace and Remove reimbursement allocation of approximately $517 million, of which about $202 million had been received by December 31, 2025. Internationally, it serves roughly 149,300 broadband and 399,200 mobile subscribers and continues to migrate customers to high-speed fiber and fixed wireless networks.

ATN highlights key risks including cybersecurity threats, severe weather and climate-related events, network outages and rising energy costs, reliance on government funding and major carrier agreements, geopolitical instability in the Caribbean, competitive pressure from larger carriers and new technologies such as low earth orbit satellite service, regulatory uncertainty in markets like Guyana and Bermuda, unionized labor and pension obligations in Alaska, and execution risk around major initiatives and capital investments. As of March 16, 2026, it had 15,367,611 common shares outstanding and a public float valued at about $231 million as of June 30, 2025.

ATN International reported fourth quarter and full-year 2025 results and issued a 2026 outlook. Fourth quarter revenue rose 2% to $184.2 million and Adjusted EBITDA increased 8% to $50.0 million, while the quarter showed a net loss of $3.3 million, or $0.32 per share.

For 2025, revenue was flat at $728.0 million, operating income improved to $28.4 million from a small loss, and net loss narrowed to $14.9 million, or $1.38 per share. Full-year Adjusted EBITDA rose 3% to $190.0 million, supported by higher cash from operations of $133.9 million and lower capital spending of $90.0 million.

High-speed broadband homes passed grew 27% year-over-year in the fourth quarter and high-speed broadband subscribers increased 3%, while total international mobile subscribers grew 3%. For 2026, ATN expects Adjusted EBITDA between $190 million and $200 million and capital expenditures between $105 million and $115 million, excluding reimbursable amounts, with potential EBITDA reduction from a pending US tower portfolio sale.

ATN International is reshaping its U.S. infrastructure footprint by agreeing to sell a portfolio of 214 Southwestern U.S. towers and related operations to an affiliate of Everest Infrastructure Partners for up to $297 million in cash.

The deal is structured with an Initial Closing, expected in the second quarter of 2026, that is projected to generate gross proceeds of about $250–$270 million, including $20–$35 million tied to post-closing conditions within twelve months. Subsequent closings of roughly $27–$47 million are anticipated over the following twelve months as specific construction and operational milestones are met.

ATN expects taxes, minority investor payments, and transaction expenses to consume about 25–30% of gross proceeds and plans to use the funds to reduce debt, invest in existing operations, and pursue select growth opportunities. Around $70 million of initial proceeds are earmarked to repay borrowings under its CoBank revolving credit facility. A leaseback and preferred backhaul arrangements allow ATN to keep using the tower sites and supply connectivity services. On a twelve‑month estimated basis, removing the Tower Portfolio is expected to reduce consolidated and U.S. Telecom segment revenue by $5–$7 million, operating income by $4–$6 million, and EBITDA by $10–$13 million.
