Filing's footnotes

1. On January 28, 2025, the Reporting Person filed a Form 4 which inadvertently understated, by 360 shares, the number of shares received upon the settlement of performance stock units that were granted on March 1, 2023 under the Amended and Restated ADTRAN Holdings, Inc. 2020 Employee Stock Incentive Plan. This amendment is being filed to correct the number of shares received and the total number of shares directly held by the Reporting Person following such settlement.

2. As a result of this amendment, the reporting person beneficially owns a total of 955,830.51 shares as of the date hereof and not 955,470.51 shares as reported on the most recent Form 4 filed by the reporting person on January 28, 2028.
