ATN International, Inc.

Human Capital Resources

People and Culture

We know that our employees are our most valuable assets to realize our mission to digitally empower people and communities so they can connect with the world and prosper. We do this through meeting the everyday connectivity needs of rural and historically underserved communities. We developed the values listed below to reflect both our current culture and the values that we strive to embody to attract and maintain key talent. We endeavor to implement these values every day through employee engagement events, regular communication on company goals and milestones, and foster a connected and empowered workplace.

ATNWorkforce Overview

As of December 31, 2024, we had approximately 2,300 employees, of whom approximately 900 were employed in the United States (including the US Virgin Islands) and approximately 1,400 were employed by our international subsidiaries. At the holding company level, we employ our executive management team and staff. Approximately 31% of our total employee population are covered by contracts with various unions. Employees represented by unions are located in Alaska and all our international markets except for the Cayman Islands. As of the end of 2024, we believe we have a good relationship with our unions.

Commitment to Local Management and Variety of Viewpoints

We seek engaged managers who have strong values, integrity, knowledge of our market and business model, and have respect for differing viewpoints. We strive to cultivate a dynamic working environment that fosters a greater understanding of our differences and strengthens our company.

We rely heavily on local management teams to run our subsidiary operating units. Many of the markets in which we operate are small and remote, and in some cases are subject to government restrictions on granting work visas, all of which makes it difficult to attract and retain talented and qualified managers and staff in those markets.

Employee Engagement and Development

Together with our subsidiaries, we are dedicated to enhancing the use of technology in the various communities we serve. We believe having management and staff with deep local expertise of the communities in which they operate is

crucial to our success and to our ability to have a positive impact on those communities. We celebrate different perspectives and backgrounds because we believe they help us to have a stronger, more creative, and more successful workplace.

We are proud to offer benefits to our employees that promote wellness and personal care, a safe work environment and career growth opportunities. We regularly utilize performance development tools for our employees, which are focused on driving engagement and high performance through frequent communication throughout the year.

Our employee engagement survey provides employees with the opportunity to share confidential feedback on what they believe has been working well and where they believe we can improve to better support our employees. Our focus areas for engagement include skills development and manager performance. Anonymous, aggregated results are shared with employees, and the results inform our long-term action plans aimed at continuously improving our work environment.
