ADTRAN Holdings Inc.

ADTRAN reported Q2 2026 revenue of $281.1 million, up 6.1% year over year. Non-GAAP gross margin was 40.7%, down from 41.4% in Q2 2025 and 43.0% in Q1 2026. Non-GAAP operating income was $10.6 million and non-GAAP operating margin was 3.8%, versus $8.0 million and 3.0% a year ago, but down from $19.9 million and 6.9% sequentially. Non-GAAP net income attributable to ADTRAN Holdings was $3.4 million, or $0.04 per diluted share, versus breakeven in Q2 2025 and $11.0 million, or $0.14 per share, in Q1. Operating cash flow was $25.9 million and free cash flow was $8.7 million. Cash and cash equivalents were $79.2 million at quarter end, down from $88.3 million at March 31, 2026, after $22.6 million of share repurchases and dividend payments. For Q3, management guided to revenue of $275 million to $295 million and non-GAAP operating margin of 1.5% to 5.5%.

Tom Stanton framed the quarter as a timing-and-supply problem rather than a demand problem. He said the customer delay was a repositioning of priorities, not destroyed demand, and repeatedly emphasized that underlying demand across end markets remains healthy. He also highlighted strategic progress in optical, hyperscaler/AI-related growth, and secure connectivity, saying the company is increasingly diversified and well positioned into 2027.

Tim Santo said the quarter’s financials were solid on a GAAPless basis but hurt by mix and supply constraints: revenue was $281.1 million, gross margin 40.7%, operating expenses $103.9 million, operating income $10.6 million, and EPS $0.04. He noted working capital improvements, including inventory of $208.8 million, DSO of 67 days, DPO of 65 days, and operating cash flow/free cash flow of $25.9 million/$8.7 million. He also said the company completed a refinancing with JPMorgan that reduced borrowing costs by 200 basis points, maintained revolver capacity, and extended maturity to 2031.

Analysts focused on whether the customer delay was demand deferred or destroyed, and Stanton said the customer recommitted to its plan and that multiple deployment buckets are still in flight. They also pressed on supply constraints and margin recovery; management said the issue is broader than memory, including optical amplifiers, silicon and even PC boards, and that better forecasting, more order coverage, pricing actions and redesigns are being used to mitigate it. Questions also covered the balance sheet, real estate, Japan activity, LPO/LiteWave timing, and exposure to Chinese transceivers; management said no major real estate announcement is ready, Japan is an existing optical market, MicroMux/LiteWave are still on track, and they do source some transceivers/pluggables from China but did not give a detailed sourcing response.
