ADTRAN Reports Q2 Revenue Below Guidance, Margins Shrink
Adtran Holdings reported preliminary, unaudited second-quarter 2026 results that miss prior guidance, due to a customer-related project delay and elevated component and freight costs. Revenue is expected to be $280.0 million to $282.0 million, below the previous guidance of $283.0 million to $303.0 million, with GAAP operating margin between (3.2)% and (4.0)% and non-GAAP margin between 3.5% and 4.0%. Diluted non-GAAP earnings per share are seen at $0.03 to $0.05, below analyst expectations of about $0.13, while GAAP earnings per share are expected to be negative. CEO Tom Stanton said the results reflect near-term headwinds but do not change the company’s overall business, customer engagement, or strategic priorities, and he remains encouraged by the optical networking business and the innovation pipeline. For Q3 2026, Adtran projects revenue of $275.0 million to $295.0 million and non-GAAP margins of 1.5% to 5.5%, with final results for Q2 to be released after the market close on August 3, 2026 and a conference call on August 4, 2026. The disclosures summarize preliminary results and indicate that final numbers may differ from the unaudited figures.
