HUNTSVILLE, Ala.--(BUSINESS WIRE)-- ADTRAN Holdings, Inc. (NASDAQ: ADTN and FSE: QH9) (鈥淎DTRAN Holdings鈥� 鈥淎DTRAN鈥� or the 鈥淐ompany鈥�) today announced its unaudited financial results for the second quarter ended June 30, 2025.

Revenue: $265.1 million, higher by 17% year-over-year.
Gross margin: GAAP gross margin: 37.3%; non-GAAP gross margin: 41.4%.
Operating margin: GAAP operating margin (5.0)%, non-GAAP operating margin 3.0%.
Net cash provided by operating activities of $32.2 million.
Cash and cash equivalents of $106.3 million, an increase of $5.0 million sequentially.

ADTRAN Holdings Chairman and Chief Executive Officer Tom Stanton stated, 鈥淲e delivered strong second quarter results with revenue growth that exceeded expectations, reflecting solid execution across our business and increasing demand. We experienced growth across all major revenue categories and gained market share in key areas. We also continued to strengthen our balance sheet with solid cash generation. These results underscore the impact of our strategic product investments and the trust customers are placing in Adtran to help them evolve and scale their networks to meet the demands of cloud, AI, and edge computing.鈥�

Mr. Stanton added, 鈥淟ooking forward, our bookings and pipeline reinforce our confidence in continued gains in profitability and cash flow. With a clear strategy, global reach, and investment in next-generation network architectures, Adtran remains well-positioned.鈥�

Business outlook¹

For the third quarter of 2025, the Company expects revenue to be within a range of $270.0 million to $280.0 million. Non-GAAP operating margin is expected to be within a range of 3.0% to 7.0%.

¹Non-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 third quarter 2025 guidance with regard to 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, amortizations and adjustments, stock-based compensation expense, restructuring expenses, integration expenses, deferred compensation adjustments, professional fees and other expenses, and goodwill impairment, 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.

The Company will hold a conference call to discuss its second quarter 2025 results on Tuesday, Aug. 5, 2025, at 9:30 a.m. Central Time (4:30 p.m. Central European Summer Time).

In addition, ADTRAN Holdings, through its senior management, may from time to time make forward-looking public statements concerning the matters described herein.

Explanation of use of non-GAAP financial measures

Set forth in the tables below are reconciliations of gross profit, gross margin, operating expenses, operating loss, operating margin, other expense, net 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 (鈥淕AAP鈥�), to non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income (loss), non-GAAP operating margin, non-GAAP other expense, non-GAAP net income (loss) 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, amortization and adjustments (consisting of intangible amortization of backlog, inventory fair value adjustments, developed technology, customer relationships, and trade names acquired in connection with business combinations), stock-based compensation expense, restructuring expenses, integration expenses, deferred compensation adjustments, goodwill impairments, 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. 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. Additionally, our calculation of non-GAAP measures may not be comparable to similar measures calculated by other companies.

(1) Includes intangible amortization of backlog, inventory fair value adjustments, 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.

(2) Includes expenses for a Business Efficiency Program designed to optimize the assets and business processes following the business combination with Adtran Networks. The Business Efficiency Program was completed as of December 31, 2024.

(3) Includes expenses related to the Company's one-time integration bonus program in connection with synergy targets as a result of the business combination with Adtran Networks which was completed as of December 31, 2024.

(1) Loss per common share attributable to ADTRAN Holdings, Inc. - basic and diluted - reflects a $1.5 million effect of redemption of RNCI for the three and six months ended June 30, 2025.

(2) Represents the non-controlling interest portion of the Company's ownership of Adtran Networks pre-DPLTA and the annual recurring compensation earned by redeemable non-controlling interests and accrued by the Company post-DPLTA.

(3) 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.

(4) Includes non-cash change in fair value of equity investments held in deferred compensation plans offered to certain employees.

(5) Includes amortization of actuarial losses related to the Company's pension plan for employees in certain foreign countries.

(6) Includes expenses for a Business Efficiency Program designed to optimize the assets and business processes following the business combination with Adtran Networks. The Business Efficiency Program was completed as of December 31, 2024.

(7) Includes expenses related to the Company's one-time integration bonus program in connection with synergy targets as a results of the business combination with Adtran Networks. Includes fees incurred for the expansion of internal controls at Adtran Networks and the implementation of the DPTLA which was completed as of December 31, 2024.

(8) $3.2 million is included in selling, general and administrative expenses on the condensed consolidated statements of loss. Includes professional fees related to an internal investigation and related employee exit costs, fees relating to other one-time professional fees and business expenses.

(9) Represents the tax effect of non-GAAP adjustments. Beginning in the period ended September 30, 2024, the Company changed its method of calculating non-GAAP income taxes by applying blended statutory tax rates to non-GAAP losses before income taxes in order to include current and deferred income tax expenses that are commensurate with the non-GAAP measure of profitability. The blended statutory tax rate is calculated using 0%, resulting in no tax benefits net of impact of valuation allowance, for the loss jurisdiction鈥檚 non-GAAP losses before income taxes and 30% for all remaining jurisdictions鈥� non-GAAP income before income taxes. Prior periods have been adjusted to reflect the application of blended statutory tax rates, net of impact of valuation allowance, to non-GAAP losses before income taxes as opposed to the previous application of blended statutory and effective tax rates to separate non-GAAP adjustments. We previously reported the tax effect of the adjustment to non-GAAP net loss under the prior method of $7.9 million and $13.5 million for the three months ended June 30, 2024 and six months ended June 30, 2024, respectively.
