ADTRAN Holdings, Inc. reports first quarter 2026 financial results 

Huntsville, Alabama, USA. — May 4, 2026 — ADTRAN Holdings, Inc. (NASDAQ: ADTN and FSE: QH9) (“ADTRAN Holdings” “ADTRAN” or the “Company”) today announced its unaudited financial results for the first quarter ended March 31, 2026.

• Revenue: $286.1 million, up 15.5% year-over-year.
• GAAP gross margin of 39.5%; Non-GAAP gross margin of 43.0%; up 108 and 55 basis points year-over-year, respectively.
• Operating margin: GAAP operating margin of 2.2 %; non-GAAP operating margin of 6.9%.
• Net cash provided by operating activities of $12.7 million.
• GAAP diluted loss per share of $0.01; non-GAAP diluted earnings per share of $0.14.
• Cash and cash equivalents of $88.3 million.

ADTRAN Holdings Chairman and Chief Executive Officer Tom Stanton stated, “We delivered solid first quarter results, with revenue increasing 15.5% year-over-year, and GAAP and non-GAAP operating margin rising 380 and 300 basis points from a year ago, respectively. These results reflect the continued strength of our core markets and the operating leverage we have been building.”

Mr. Stanton added, “We believe that the demand drivers underpinning our business continue to build. In the US, broadband momentum continues with BEAD deployment funds now beginning to reach operators in a growing number of states. In Europe, high-risk vendor displacement continues to progress, reinforced by the European Commission's advancing legislation such as Cybersecurity Act 2.0. Also during the quarter, we introduced LiteWave800™, our first product purpose-built for intra-data center AI infrastructure, setting a new benchmark for power efficiency at 800G.”

Business outlook¹

For the second quarter of 2026, the Company expects revenue to be within a range of $283.0 million to $303.0 million. Non-GAAP operating margin is expected to be within a range of 5.0% to 9.0%.

¹ 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 second 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.

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 and our Form 10-Q for the quarterly period ended March 31, 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 income (loss), operating margin, other expense, net income (loss) 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 attributable to the Company, non-GAAP net earnings 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, 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. 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.
