EXHIBIT 99.1

ADTRAN Holdings, Inc. Reports Earnings for the Third Quarter of 2022 and Declares Quarterly Cash Dividend

HUNTSVILLE, Ala. — (November 7, 2022) — ADTRAN Holdings, Inc., (NASDAQ: ADTN and FSE: QH9) (“ADTRAN Holdings” or the “Company”), today announced financial results for the third quarter of 2022. For the quarter, revenue was $340.7 million. Net loss inclusive of the non-controlling interest for the third quarter of 2022 was $44.9 million. Net loss attributable to the Company for the third quarter of 2022 was $41.9 million and loss per share attributable to the Company was $0.57. Net loss and loss per share are inclusive of consolidated financial results, significant purchase accounting adjustments, and certain one-time transaction expenses related to the business combination of the Company, ADTRAN, Inc. (“ADTRAN”), and ADVA Optical Networking SE (“ADVA”). Inclusive of non-controlling interests, non-GAAP net income was $12.2 million. Non-GAAP net income attributable to the Company was $7.7 million and non-GAAP diluted earnings per share attributable to the Company was $0.11. Non-GAAP net income and non-GAAP earnings per share 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 and amortization of inventory fair value adjustments), stock-based compensation expense, amortization of pension actuarial losses, deferred compensation adjustments, certain asset impairments, changes in valuation allowance related to our deferred tax assets, and the tax effect of these adjustments to net income. The reconciliations between the non-GAAP net income measures presented herein and the respective equivalent GAAP financial measures are set forth in the tables provided below.

ADTRAN Holdings Chairman and Chief Executive Officer Tom Stanton stated, “Our third quarter marked a new era in our history as we closed the business combination agreement with ADVA Optical Networking SE. The combined company’s broader portfolio, paired with a larger, more diversified, and regionally balanced customer base, positions us to capitalize on the global fiber conversion. The Q3 results highlight our increased market presence in optical networking and subscriber solutions, two portfolio categories that complement our continued success in fiber access. This success reinforces the positive outlook we have in our ability to maximize our growth potential in the ongoing global investment cycle in fiber networks.”

The Company also announced that its Board of Directors declared a cash dividend for the third quarter of 2022. The quarterly cash dividend of $0.09 per common share is to be paid to the Company’s stockholders of record as of the close of business on November 22, 2022. The ex-dividend date is November 21, 2022, and the payment date will be December 6, 2022.

Cautionary Note Regarding Forward-Looking Statements

This press release contains forward-looking statements, generally identified by the use of words such as “believe,” “expect,” “intend,” “estimate,” “anticipate,” “will,” “may,” “could” and similar expressions, which forward-looking statements reflect management’s best judgment based on factors currently known. However, these statements involve risks and uncertainties, including: (i) risks and uncertainties related to the continued impact of the SARS-CoV-2 coronavirus/COVID-19 global pandemic (including variants of the SARS-CoV-2 coronavirus), including with respect to continued manufacturing and supply chain constraints; (ii) risks and uncertainties related to the completed business combination between the Company, ADTRAN and ADVA, including risks related to regulatory or other limitations imposed following the closing of the business combination on July 15, 2022 and the proposed domination and profit and loss transfer agreement between the Company as the controlling entity, and ADVA as the controlled entity; the ability to successfully integrate the ADTRAN and ADVA businesses; risks related to disruption of management time from ongoing business operations due to integration efforts following the business combination; the risk that the business combination could have adverse effects on the market

price of ADTRAN Holdings’ common stock or ADVA’s common shares or the ability of the Company, ADTRAN, and ADVA to retain customers, retain or hire key personnel, maintain relationships with their respective suppliers and customers, and on their operating results and businesses generally; the risk that ADTRAN Holdings may be unable to achieve expected synergies or that it may take longer or be more costly than expected to achieve those synergies; the risk of fluctuations in revenue due to lengthy sales and approval processes required by major and other service providers for new products; the risk posed by potential breaches of information systems and cyber-attacks; the risks that ADTRAN, ADVA or ADTRAN Holdings may not be able to effectively compete, including through product improvements and development; and (iii) other risks set forth in ADVA’s annual and interim financial reports made publicly available and ADTRAN’s and ADTRAN Holdings’ public filings made with the Securities and Exchange Commission, including ADTRAN’s Annual Report on Form 10-K for the year ended December 31, 2021 and ADTRAN Holdings’ Form 10-Q for the quarterly period ended June 30, 2022. These risks and uncertainties could cause actual results to differ materially from those in the forward-looking statements included in this press release.

Explanation of Use of Non-GAAP Financial Measures

Set forth in the tables below are reconciliations of operating loss, net loss inclusive of the non-controlling interest, net loss attributable to the Company, and loss per share attributable to the Company, in each case as reported based on generally accepted accounting principles in the United States (“GAAP”), to non-GAAP operating income, non-GAAP net income inclusive of the non-controlling interest, non-GAAP net income attributable to the Company, and non-GAAP diluted earnings per share attributable to the Company, 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 and amortization of inventory fair value adjustments), stock-based compensation expense, amortization of pension actuarial losses, deferred compensation adjustments, certain asset impairments, changes in valuation allowance related to our deferred tax assets, and the tax effect of these adjustments to net income. These measures are used by management in our ongoing planning and annual budgeting processes. Additionally, we believe the presentation of non-GAAP operating income, non-GAAP net income inclusive of the non-controlling interest, non-GAAP net income attributable to the Company, and non-GAAP diluted earnings per share attributable to the Company, 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 operating income, non-GAAP net income and non-GAAP earnings per share - basic and diluted, may not be comparable to similar measures calculated by other companies.
