Investigation Details
ADTRAN Holdings shares shares fell approximately 15% on July 22, 2026 after the company announced preliminary unaudited Q2 2026 revenue of $280 million to $282 million and non-GAAP operating margin of about 3.5% to 4.0%, both below its guidance of $283 million to $303 million in revenue and 5% to 9% non-GAAP operating margin.
On the Q1 2026 call, CFO Timothy Santo stated: "We expect revenue to be between $283 million and $303 million, and non-GAAP operating margin within a range of 5% to 9%." The preliminary figures placed revenue $1 million to $23 million below that range and operating margin at least 100 basis points below the bottom of the stated range.
An investor presentation attached to a May 5, 2026 Form 8-K reported revenue of $286.1 million, up 15.5% year-over-year and within prior guidance of $275 million to $295 million. The preliminary Q2 revenue range of $280 million to $282 million was approximately $4.1 million to $6.1 million below analyst consensus estimate.
