ADTRAN Holdings Postpones 2025 Annual Meeting of Stockholders

HUNTSVILLE, Ala.--(BUSINESS WIRE)-- ADTRAN Holdings, Inc. (NASDAQ: ADTN and FSE: QH9) (“ADTRAN Holdings” or the “Company”), announced today that it is postponing its 2025 annual meeting of stockholders (the “Annual Meeting”), originally scheduled to be held on May 14, 2025, as disclosed in the Company’s Form 8-K filed with the Securities and Exchange Commission earlier today (the “Form 8-K”). As described in the Form 8-K, the Company is in the process of restating its financial statements as of and for the years ended December 31, 2024 and 2023 and certain interim periods in 2024 (the “Restatements”). The Company does not expect the Restatements to set forth material changes to the financial information presented in the Company’s preliminary earnings release dated May 7, 2025 (the “Preliminary Earnings Release”). Nevertheless, the Annual Meeting is being postponed to allow the Company additional time to complete the process and to provide stockholders with ample time to review the restated financial statements.

Tim Santo, Adtran’s SVP and CFO, commented, “While the timing is unfortunate and requires the postponement of the annual meeting of stockholders, we are fully committed to filing the restatements on or before May 19, and we do not expect the restatements to set forth material changes to the financial information presented in the preliminary earnings release.”

Completion and filing of the Restatements with the SEC are expected to be completed as soon as practicable, at which time the Company will notify stockholders of the new date and time of its Annual Meeting.
