ATN International, Inc.

In addition to the other information set forth in this Report, you should carefully consider the factors discussed under Part I, Item 1A “Risk Factors” of our 2024 Annual Report on Form 10-K. The risks described herein and in our 2024 Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

The U.S. government shutdown may adversely impact our operations and financial results.

The U.S. federal government has been shut down since October 1, 2025. A prolonged government shutdown may adversely impact the operations and financial results of the Company because we rely on many government functions that are limited or ceased during this shutdown. For example, delays in the issuance, review and approval of permit applications may delay the Company’s construction timelines, which may increase our costs or impact our ability to meet contractual commitments or compliance obligations. Disruption to government awards, including delayed awards and delayed or halted payments or project funding may have an impact on the Company’s financial results if reimbursements are delayed. The backlog in review and approvals that is accumulating during this period of shutdown may also contribute to further delays even after government operations resume.

Geopolitical instability and U.S. military presence in the Caribbean may impact our operations.

A substantial part of our operations is located in the Caribbean and we have undersea cable connectivity and corporate functions in several jurisdictions, including Trinidad and Tobago. The U.S. military has been increasing its presence in the Caribbean recently. There are a number of potential business and operational impacts in the event that military activity escalates, such as physical damage to our telecommunications and subsea infrastructure, impairment to critical infrastructure and facilities (like power), workforce disruptions, changes to customer base and competitive markets, inability to travel, as well as macroeconomic risks like currency fluctuation, oil and gas prices and general market instability. Any further geopolitical volatility, including the threat of or actual military action, may adversely impact our operations and financial results.
