EX-99.1

Exhibit 99.1

Corrected Financial Information

On August 6, 2023, ADTRAN Holdings, Inc. (the “Company”) issued a press release that reported the Company’s financial results for the fiscal quarter and six months ended June 30, 2023 (the “Earnings Release”). A copy of the Earnings Release was attached as Exhibit 99.1 to the Company’s Current Report on Form 8-K that was furnished to the Securities and Exchange Commission on August 7, 2023. As disclosed in the Company’s Current Report on Form 8-K filed with the SEC on August 10, 2023 (the “August 10, 2023 Form 8-K”), subsequent to Company’s second fiscal quarter earnings call on August 8, 2023 and during the preparation of its unaudited condensed consolidated financial statements to be included in the Company’s Form 10-Q for the second fiscal quarter ended June 30, 2023 (the “Q2 Form 10-Q”), the Company determined that the principal amount of indebtedness outstanding under the Company’s revolving credit facility with a syndicate of banks, including Wells Fargo Bank, National Association (“Wells Fargo”), should be classified as noncurrent liabilities on the Company’s consolidated balance sheet. Therefore, the outstanding Wells Fargo revolving credit facility balances for the following prior periods were misclassified in the Earnings Release and have been adjusted from current to noncurrent liabilities on the balance sheets set forth in the Earnings Release as follows: $60.0 million as of December 31, 2022, and $200.0 million as of June 30, 2023. The adjustment of credit facility balances did not have any impact on, or result in any change to, the consolidated statements of income (loss), statements of cash flows and non-GAAP measures presented in the Earnings Release. Furthermore, the Company corrected an error in a supplemental disclosure of cash financing activities in the condensed consolidated statements of cash flow that appeared in the Earnings Release – cash used in operating activities related to operating leases, which amount for the six months ended June 30, 2023 should have been $5.082 million rather than $4.502 million.

Corrected versions of the condensed consolidated balance sheets and condensed consolidated statements of cash flows appearing in the Earnings Release are provided below (with the corrected or restated information identified by a “^”):
