On July 22, 2026, ADTRAN announced preliminary Q2 2026 revenue of $280 million to $282 million and non-GAAP operating margin of about 3.5% to 4.0%, below the Company’s prior guidance of $283 million to $303 million in revenue and non-GAAP operating margin of 5% to 9%. In ADTRAN’s press release announcing preliminary results, Tom Stanton, Chairman and CEO, said “Our preliminary second quarter results were directly impacted by a project delay from a single customer. In addition, margins reflected the current elevated component and freight cost environment.”
 
On ADTRAN’s Q1 2026 call, CFO Timothy Santo had 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 Q2 revenue was $1 million to $23 million below the guidance, and the non-GAAP operating margin was at least 100 basis points below the guidance.
 
Additionally, 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 2026 revenue of $280 million to $282 million was approximately $4.1 million to $6.1 million below analyst consensus estimate.
 
 On this news, ADTRAN stock declined by $1.69 per share, or approximately 14%, to close at $10.45 per share on July 22, 2026.
