Adtran Holdings Holdings reported preliminary unaudited Q2 2026 revenue of $280 million to $282 million and non-GAAP operating margin of 3.5% to 4.0%, both below its prior guidance of $283 million to $303 million and 5% to 9%, respectively. The company attributed the shortfall to a delay on a single-customer project. Following the July 22, 2026 disclosure, ADTN shares fell approximately 15%. Levi & Korsinsky, a shareholder rights law firm, launched an investigation into whether Adtran Holdings adequately disclosed risks related to customer concentration and project timing. The investigation reviews statements by CFO Timothy Santo and CEO Thomas Stanton regarding guidance and demand outlook. Investors who suffered losses are encouraged to contact the firm.
