ATN International, Inc.

Our subsidiary, One Communications (Guyana) Inc. (formerly known as GTT Inc.) (“OneGY”), in which we hold an 80% interest, operates in Guyana pursuant to a telecommunications license issued by the Government of Guyana. OneGY is subject to regulation under the Guyana Public Utilities Commission Act of 2016, as amended, and the Guyana Telecommunications Act of 2016 and the regulations promulgated thereunder. The Public Utilities Commission of Guyana is an independent statutory body responsible for regulating telecommunications rates and services in Guyana. The Prime Minister of Guyana, acting on behalf of the Government of Guyana, holds statutory authority over telecommunications licensing and related matters. The Telecommunications Agency advises the Prime Minister, implements policy and has primary responsibility for issuing operating licenses and frequency authorizations.

Subsequent to the sector’s liberalization, OneGY has historically been able to implement price adjustments and undertake equipment upgrades with support from the relevant regulatory authorities. However, uncertainty persists regarding the long-term frameworks governing licensing, universal service funding, and spectrum management. These uncertainties create potential variability in the regulatory and competitive landscape in Guyana.

On October 5, 2020, the Prime Minister of Guyana formally implemented telecommunications legislation enacted in 2016 that introduces significant changes to Guyana’s existing telecommunications regulatory regime with the stated objective of fostering a more competitive market. These regulations impose new sector-wide requirements affecting our operations, administrative reporting obligations, and service offerings. There can be no assurance that these regulations will be administered in a manner that does not adversely impact OneGY’s operational or financial performance.

*Licensing Framework.*OneGY provides domestic fixed wireline, mobile and international voice and data services pursuant to licenses issued by the Government of Guyana. OneGY’s current operating license was issued in

October 2020 and is scheduled to expire in October 2030. On October 6, 2025, we formally notified the Government of Guyana of our intention to renew our operating license. As of the date of the Report, the request remains pending.
