Remarks by Michael Prior, ATN CEO

“The growth in revenues and our customer base contributed to margin improvement and Adjusted EBITDA expansion, tracking to our three-year plan. Over the past year, we have increased the number of homes passed by fiber and other high-speed networks by 66%. This has led to 22% growth in our high-speed data subscribers as we have upgraded legacy broadband users and brought on new subscribers. This early success improves the durability of our revenue further validating our Glass & Steel^TM and First-to-Fiber strategies. Also, we were pleased with the 14% growth in international mobile subscribers.

“As expected, we closed a major, long-term contract with a national mobile carrier during the quarter to provide network, infrastructure, and technical services. This long-term contract leverages our operating capabilities and a mobile network covering more than 50,000 square miles of the western United States.

“Our long-term track record of strong operational and financial performance provided the foundation to refinance our main credit facility on attractive terms despite the current market environment. The new facilities have five- and six-year maturities, adding to our financial strength and flexibility. As we enter the latter stages of our three-year fiber-driven expansion, our focus is shifting toward increasing free cash flow and reducing our leverage ratio, as we anticipate network spending to moderate while growing our subscriber base and recurring revenue on this expanded and upgraded network footprint.”

Second Quarter 2023 Financial Results

Consolidated revenues were $186.4 million, up 4% versus $179.5 million in the year-ago quarter. This increase primarily reflects higher mobility and fixed revenues, including those from a recent acquisition, partially offset by lower legacy roaming and construction revenues.

Operating income rose to $2.4 million, from $1.7 million in the year-ago quarter. The year-over-year increase was primarily due to higher revenues, partially offset by an increase in operating and depreciation expenses from a recent acquisition.

Net income attributable to ATN stockholders increased to $0.8 million, and a net loss of $(0.03) per share, compared with a net loss attributable to ATN stockholders of $(0.5) million, or $(0.11) loss per share, in the year-ago quarter. The improvement in net income was due primarily to an increase in operating income, an income tax benefit and income from non-controlling investments, partially offset by a $6.1 million increase in interest expense. In both periods, the loss per share calculation includes the impact of preferred dividends that are not included in the net income (loss) calculation.

Adjusted EBITDA¹ increased to $45.8 million, from $41.7 million in the year-ago quarter.

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

Use of Non-GAAP Financial Measures and Definition of Terms

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, and the gain (loss) on disposition of assets. To more closely align with similar calculations presented by companies in its industry, beginning in this first quarter of 2023, the Company excluded non-cash stock-based compensation in its adjustment to derive Adjusted EBITDA. Prior periods have been restated to conform to this definition change.

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 trailing four quarters’ ended total 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.

Cautionary Language Concerning Forward-Looking Statements
