Beverly, MA – April 24, 2024 – ATN International, Inc. (“ATN” or the “Company”) (Nasdaq: ATNI), a leading provider of digital infrastructure and communications services, today reported financial results for the quarter ended March 31, 2024.

Remarks by Brad Martin, ATN Chief Executive Officer

“The ATN team continues to execute on our First-to-Fiber and Glass & Steel™ strategies to expand our fiber-rich digital infrastructure and next generation fixed wireless capabilities. While we saw growth in our operational metrics year-over-year, our first quarter financial results were below our expectations. In the International Telecom segment, we saw revenue and Adjusted EBITDA growth of 3%, respectively, reflecting the growth in our high-speed broadband subscribers. This growth was offset by a 2% decline in US Telecom revenues and a 9% decline in Adjusted EBITDA for the segment. The US Telecom results reflect delays in major carrier services projects and weaker than expected business revenues.

“We are revising our Fiscal Year 2024 guidance to reflect the softer than expected first quarter results and our current expectations for the balance of the year. While our International Telecom segment is expected to show continued year-on-year growth, the carrier services project delays from the first quarter are expected to create headwinds impacting the US Telecom segment throughout the year. To address this shortfall, our priorities are working to recover the project delivery schedule, pursuing and closing business revenue pipeline opportunities, and accelerating actions to drive the Company toward higher margin levels.

Additionally, we are reducing our capital expenditures for 2024 in line with the delays in certain projects and lowering our Adjusted EBITDA expectations as we prioritize improving operating cash flow. We believe that our investments are important to expand the longevity of our network and position us to enhance shareholder value over time.”

First Quarter 2024 Financial Results

Consolidated revenues were $186.8 million, up 1% versus $185.8 million in the year-ago quarter. This increase primarily reflects higher fixed revenues in the International segment, as well as higher construction and other revenues, which were largely offset by lower carrier services revenue in the US Telecom Segment and a decline in consumer mobile revenue.

Operating income was $4.6 million in the first quarter versus $0.6 million in the year-ago quarter. The increase was primarily due to lower restructuring expenses and a reduction in depreciation and amortization expenses year-over-year.

Net loss attributable to ATN stockholders in the first quarter of 2024 was $(6.3) million, or a loss of $(0.50) per share compared with a net loss attributable to ATN stockholders of $(5.9) million, or $(0.44) loss per share, in the year-ago quarter. The increase in the net loss attributable to ATN stockholders was the result of an increase in interest and income tax expenses, partially offset by decreases in depreciation, amortization and restructuring expenses. In all periods, the loss per share calculation includes the impact of preferred dividends that are not included in the net loss calculation.

Adjusted EBITDA1 decreased to $43.5 million in the first quarter of 2024 from $44.8 million in the year-ago quarter due to higher costs of services and other, which more than offset the increase in revenue.

The Company recorded financial results in three categories: (i) International Telecom; (ii) US Telecom; and (iii) Corporate and Other.

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 expenses, one-time impairment or special charges, non-cash stock-based compensation, and the gain (loss) on disposition of assets.

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 sum of the trailing four quarters 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. 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.
