ATN International plunges 16% on earnings miss despite revenue beat
Telecom provider posts larger-than-expected loss, but maintains 2026 guidance amid broadband expansion
ATN International shares tumbled more than 16% in after-hours trading Tuesday after the telecommunications provider reported fourth-quarter earnings that fell far short of analyst expectations, overshadowing a modest revenue beat and signs of operational progress.
The Beverly, Massachusetts-based company posted a net loss of $3.3 million, or 32 cents per share, for the quarter ended December 31, compared with analyst estimates for a loss of just 6 cents per share. The shortfall represents a 433% earnings miss, a stark reversal for a stock that had gained 28.5% year-to-date before the earnings release, according to StockTitan.
Revenue of $184.2 million edged past the $182.4 million consensus estimate, marking a 2% year-over-year increase. The top-line performance was supported by an 8% increase in adjusted EBITDA to $50 million, with high-speed broadband homes passed expanding 27% as the company continued investing in network infrastructure.
The quarterly loss included a $5.3 million write-down of an equity investment, which significantly impacted the bottom line. Despite this one-time charge, investors focused on the earnings shortfall, sending the stock down to $25.06 in extended trading, erasing nearly $70 million in market capitalization. The company currently trades at a market valuation of approximately $447 million, according to market data.
"ATN International released its Q4 and Full Year 2025 financial results on March 4, 2026, with a conference call on March 5, 2026," according to MarketBeat's earnings call summary. "Management provided a 2026 outlook expecting modest Adjusted EBITDA growth and disciplined capital spending, including an anticipated sale of certain U.S. tower assets in Q2 2026."
The company maintained its 2026 adjusted EBITDA guidance of $190 million to $200 million, suggesting confidence in its longer-term trajectory despite the quarterly earnings disappointment. The net debt ratio improved to 2.36 times from 2.54 times in the prior quarter, indicating progress on balance sheet management.
For the full year 2025, revenue reached $728 million, essentially flat year-over-year, while adjusted EBITDA increased 3% to $190 million. The company provides telecommunications services across the United States, the Caribbean, and Bermuda, positioning itself in both developed and emerging markets.
Analysts have maintained a price target of $39 on the stock, representing significant upside potential even after Wednesday's decline, according to Nasdaq data. The shares remain well below their 52-week high of $30.39 but above the year's low of $13.13, reflecting increased volatility around the earnings announcement.
The steep drop highlights investor sensitivity to earnings misses even when companies demonstrate progress on key operational metrics such as broadband expansion and EBITDA growth. With 35.5% insider ownership and 58.9% institutional holding, the stock's reaction may prompt management to provide more detailed guidance on the path to profitability during Thursday's conference call.
The company's diversified geographic footprint and ongoing broadband investments could provide growth opportunities in coming quarters, but investors will likely seek clarity on the timing of improved profitability and the impact of the anticipated tower asset sale on the balance sheet.
