Open the filing on EDGARADTRAN Holdings, Inc. reports third quarter 2026 financial results
Huntsville,
Alabama, USA. - November 2, 2026 - ADTRAN Holdings, Inc. (NASDAQ: ADTN and FSE: QH9) (“ADTRAN Holdings” “ADTRAN” or the “Company”) today announced its unaudited financial results for the third quarter ended September 30, 2026.
Revenue: $281.2 million, up 0.6% year-over-year.
GAAP gross margin of 38.5%; non-GAAP gross margin of 42.1%, including benefit of approximately 200 basis points from IEEPArefunds.
GAAP operating margin of -0.3%; non-GAAP operating margin of 5.0%.
Net cash used in operating activities of $24.5 million.
GAAP diluted loss per share of $0.10; non-GAAP diluted earnings per share of $0.09.
Cash, cash equivalents and restricted cash of $71.7 million.
ADTRAN Holdings Chairman and Chief Executive Officer Tom Stanton stated, “Third quarter revenue came in slightly below the midpoint of our guidance range as we continued to navigate a challenging supply environment. Despite these pressures, we saw encouraging developments across the business, including continued growth in optical networking and increasing growth with hyperscale customers. The rapid expansion of AI infrastructure is reshaping network investment priorities, creating opportunities for ADTRAN not only in cloud infrastructure but also across our traditional service provider markets.”
“Looking ahead, we see significant opportunities to build on this momentum as customers invest in network capacity, performance and security,” Stanton continued. “Our focus is on addressing the supply and cost pressures affecting our business, maintaining financial discipline and translating these opportunities into stronger revenue growth, profitability and cash generation.”
Business outlook
For the fourth quarter of 2026, the Company expects revenue to be within a range of $272.0 million to $292.0 million. Non-GAAP operating margin is expected to be within a range of 1.0% to 5.0% reflecting historical seasonality, availability of supply and timing of large customer projects.
International Emergency Economic Powers Act
Non-GAAP operating margin (which is calculated as non-GAAP operating income (loss) divided by revenue) is a non-GAAP financial measure. The Company has provided guidance for its fourth quarter 2026 non-GAAP operating margin. This measure excludes from the corresponding GAAP financial measure the effect of adjustments as described below. The Company has not provided a reconciliation of such non-GAAP guidance to guidance presented on a GAAP basis because it cannot predict and quantify without unreasonable effort all of the adjustments that may occur during the period due to the difficulty of predicting the timing and amounts of various items within a reasonable range. In particular, non-GAAP operating margin excludes certain items, such as acquisition related expenses, amortization and adjustments, stock-based compensation expense, deferred compensation adjustments, professional fees and other expenses, amortization of pension actuarial losses, the tax effect of these adjustments to net loss and purchases of property, plant and equipment, and developed technologies, that the Company is unable to quantitatively predict. Depending on the materiality of these items, they could have a significant impact on the Company's GAAP financial results.

In addition, ADTRAN Holdings, through its senior management, may from time to time make forward-looking public statements concerning the matters described herein. All such projections and other forward-looking information speak only as of the date hereof, and ADTRAN Holdings undertakes no duty to publicly update or revise such forward-looking information, whether as a result of new information, future events, or otherwise, except to the extent as may be required by law. All such forward-looking statements are estimates and reflect management’s best judgment based upon current information. Actual events or results may differ materially from those anticipated in these forward-looking statements as a result of a variety of factors. While it is impossible to identify all such factors, factors which have caused and may in the future cause actual events or results to differ materially from those estimated by ADTRAN Holdings include, but are not limited to: (i) risks and uncertainties relating to our ability to remain in compliance with the covenants set forth in and satisfy the payment obligations under our credit agreement and convertible notes, to satisfy our payment obligations to Adtran Networks’ minority shareholders under the Domination and Profit and Loss Transfer Agreement between us and Adtran Networks (the “DPLTA”), and to make payments to Adtran Networks in order to absorb its annual net loss pursuant to the DPLTA; (ii) the risk of fluctuations in revenue due to lengthy sales and approval processes required by major and other service providers for new products, as well as shifting customer spending patterns; (iii) risks and uncertainties related to our inventory practices and ability to match customer demand; (iv) risks and uncertainties relating to our level of indebtedness and our ability to generate cash; (v) risks and uncertainties relating to ongoing material weaknesses in our internal control over financial reporting; (vi) risks posed by changes in general economic conditions and monetary, fiscal and trade policies, including tariffs; (vii) risks and uncertainties relating to our international operations, including potential exposure to ongoing military conflicts (including the conflicts in Iran, Ukraine, and Israel and the surrounding areas); (viii) risks posed by potential breaches of information systems and cyber-attacks (ix) the risk that we may not be able to effectively compete, including through product improvements and development; and (x) the other risks set forth in our public filings made with the Securities and Exchange Commission (the “SEC”), including our most recent Annual Report on Form 10-K for the year ended December 31, 2025, our Form 10-Q for the quarterly period ended March 31, 2026, our Form 10-Q for the quarterly period ended June 30, 2026 and our Form 10-Q for the quarterly period ended September 30, 2026 to be filed with the SEC.
Explanation of use of non-GAAP financial measures
Set forth in the tables below under the heading “Supplemental Information” are reconciliations of cost of revenue, gross profit, gross margin, operating expenses, operating (loss) income, operating margin, other income (expense), net (loss) income inclusive of the non-controlling interest, net loss attributable to the Company, and loss per share - basic and diluted, attributable to the Company, and net cash provided by operating activities, in each case as reported based on generally accepted accounting principles in the United States (“GAAP”), to non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP operating margin, non-GAAP other expense, non-GAAP net income inclusive of the non-controlling interest, non-GAAP net income (loss) attributable to the Company, non-GAAP net earnings (loss) per share - basic and diluted, attributable to the Company, and free cash flow, respectively. Such non-GAAP measures exclude acquisition-related expenses, amortizations and adjustments (consisting of intangible amortization of backlog, developed technology, customer relationships, and trade names acquired in connection with business combinations), stock-based compensation expense, professional fees and other expenses, restructuring expenses, deferred compensation adjustments, amortization of pension actuarial losses, the tax effect of these adjustments to net loss and purchases of property, plant and equipment, and developed technologies. These measures are used by management in our ongoing planning and annual budgeting processes. Additionally, we believe the presentation of these non-GAAP measures, when combined with the presentation of the most directly comparable GAAP financial measure, is beneficial to the overall understanding of ongoing operating performance of the Company. These non-GAAP financial measures are not prepared in accordance with, or an alternative for, GAAP and therefore should not be considered in isolation or as a substitution for analysis of our results as reported under GAAP. Furthermore, our calculation of non-GAAP measures may not be comparable to similar measures calculated by other companies.

(1) Includes intangible amortization of backlog, developed technology, customer relationships, and trade names acquired in connection with business combinations. We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures. Such charges are significantly impacted by the timing and magnitude of our acquisitions. We exclude these charges for the purpose of calculating our non-GAAP measures, primarily because they are noncash expenses and our internal benchmarking analyses evidence that many industry participants and peers present non-GAAP financial measures excluding intangible asset amortization. Although this does not directly affect our cash position, the loss in value of intangible assets over time can have a material impact on the equivalent GAAP earnings measure.
