Earnings Conference Call

Beverly, MA – October 29, 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 September 30, 2024.

Remarks by Brad Martin, ATN Chief Executive Officer

“We reported strong free cash flow from operations in the third quarter, driven by effective cost and net working capital management. Our performance continues to reflect a tale of two segments, with revenues impacted primarily by underperformance in our US Telecom segment related to the conclusion of certain government subsidy programs, slower consumer growth, and delays in enterprise sales and delivery. Based on these dynamics, and compression in market multiples, we recorded a non-cash $35 million goodwill impairment charge during the third quarter.

“In the International Telecom segment, solid fixed revenue gains and business mobility revenue growth offset softness in consumer mobility related to competitive pressures, and we delivered Adjusted EBITDA growth. Additionally, we increased our international post-paid mobile subscriber bases both sequentially and year-over-year.

“To reflect our expectations for near-term operating performance, we are lowering our revenue and Adjusted EBITDA guidance ranges for fiscal 2024 and increasing our expected leverage multiple exiting the year. We are taking strategic actions intended to align our cost structure with current revenue levels, while focusing on margin improvement and cash flow generation. These actions include refocusing efforts on growing our business and carrier customer revenues in the US, strengthening sales execution teams, and maximizing value from deployed assets.

“Longer term, we remain committed to leveraging the value and longevity of our upgraded network while diligently operating the business in an effort to further expand cash flows and position ATN to deliver increased value for shareholders.”

Third Quarter 2024 Financial Results

Consolidated revenues were $178.5 million, down 7% versus $191.0 million in the year-ago quarter. This primarily reflects the overall revenue decline in the US Telecom segment due in part to the anticipated impact of the end of the Emergency Connectivity Fund (ECF) and Affordable Care Program (ACP), and a reduction in construction revenues for the quarter.

Operating loss was $38.4 million in the third quarter versus operating income of $6.8 million in the year-ago quarter. The decrease in operating income was primarily due to a $35.3 million non-cash goodwill impairment charge on certain US Telecom assets, $3.8 million of transaction-related charges, and $2.3 million of restructuring and reorganization expenses.

Net loss attributable to ATN stockholders in the third quarter of 2024 was $32.7 million, or a loss of $2.26 per share compared with a net loss attributable to ATN stockholders of $3.6 million, or $0.31 loss per share, in the year-ago quarter. The year-over-year change was the result of the above-mentioned factors that increased the operating loss combined with an increase in interest expense. 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 was $45.7 million in the third quarter of 2024, a decrease from $47.8 million in the year-ago quarter primarily due to lower US Telecom revenues.

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

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.
