 <p style="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman;font-weight:bold"><span style="white-space:nowrap">Item&#160;4.02&#160;&#160;&#160;&#160;Non-Reliance</span> on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review. </p> <p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Subsequent to ADTRAN Holdings, Inc.&#8217;s (the &#8220;Company&#8221;) second fiscal quarter earnings call on August&#160;8, 2023 and during the preparation of its unaudited condensed consolidated financial statements to be included in the Company&#8217;s Form <span style="white-space:nowrap">10-Q</span> for the second fiscal quarter ended June&#160;30, 2023 (the &#8220;Q2 Form <span style="white-space:nowrap">10-Q&#8221;),</span> the Company determined that the principal amount of indebtedness outstanding under the Company&#8217;s revolving credit facility with a syndicate of banks, including Wells Fargo Bank, National Association (&#8220;Wells Fargo&#8221;), should be classified as noncurrent liabilities on the Company&#8217;s consolidated balance sheet. Therefore, the outstanding Wells Fargo revolving credit facility balances for the following prior periods were misclassified and will be adjusted from current to noncurrent liabilities on the balance sheets as follows: $60.0&#160;million as of September&#160;30, 2022, $60.0&#160;million as of December&#160;31, 2022, and $180.0&#160;million as of March&#160;31, 2023. </p> <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On August&#160;10, 2023, the Audit Committee of the Board of Directors (the &#8220;Audit Committee&#8221;) of the Company concluded, after considering the recommendations of management and discussing with the Company&#8217;s independent registered public accounting firm, PricewaterhouseCoopers LLP (&#8220;PwC&#8221;), that (i)&#160;the Company&#8217;s unaudited condensed consolidated financial statements as of and for the quarter and <span style="white-space:nowrap"><span style="white-space:nowrap">year-to-date</span></span> period ended September&#160;30, 2022 included in the Company&#8217;s Quarterly Report on Form <span style="white-space:nowrap">10-Q</span> for the fiscal quarter ended September&#160;30, 2022, (ii)&#160;the Company&#8217;s audited consolidated financial statements as of and for the year ended December&#160;31, 2022 included in the Company&#8217;s Annual Report on Form <span style="white-space:nowrap">10-K</span> for the fiscal year ended December&#160;31, 2022, and (iii)&#160;the Company&#8217;s unaudited condensed consolidated financial statements as of and for the quarter ended March&#160;31, 2023 included in the Company&#8217;s Quarterly Report on Form <span style="white-space:nowrap">10-Q</span> for the fiscal quarter ended March&#160;31, 2023, respectively (collectively, the <span style="white-space:nowrap">&#8220;Non-Reliance</span> Periods&#8221;), should not be relied upon due to the above described misclassification and need to be restated. Additionally, the Audit Committee concluded that management&#8217;s report on internal control over financial reporting as of December&#160;31, 2022, the opinion of PwC on the Company&#8217;s consolidated financial statements as of and for fiscal year ended December&#160;31, 2022 and the opinion of PwC on the effectiveness of the Company&#8217;s internal control over financial reporting as of December&#160;31, 2022, should also no longer be relied upon. As a result of these errors in the Company&#8217;s financial statements, investors also should no longer rely upon the balance sheets in the Company&#8217;s earnings releases for the <span style="white-space:nowrap">Non-Reliance</span> Periods or the balance sheet in the Company&#8217;s earnings release for the quarter ended June&#160;30, 2023 that was issued on August&#160;6, 2023 (the &#8220;Q2 2023 Earnings Release&#8221;) or other communications relating to these balance sheets. </p> <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Furthermore, in connection with the restatement of the December&#160;31, 2022 financial statements, the Company will also correct certain errors related to the presentation of deferred tax assets (&#8220;DTAs&#8221;) and deferred tax liabilities (&#8220;DTLs&#8221;) in the balance sheets that were previously assessed as immaterial errors and that had been corrected in the Company&#8217;s Form <span style="white-space:nowrap">10-Q</span> for the quarter ended March&#160;31, 2023. </p> <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Neither the adjustment of credit facility balances nor the correction of the presentation of DTAs and DTLs on the balance sheets have any impact on, or result in any change to, the Company&#8217;s reported statements of income (loss) or statements of cash flows. Additionally, the misclassification has no adverse impact on the Company&#8217;s liquidity and capital resources or the maturity date of the Wells Fargo credit facility, which matures in July 2027. Moreover, the misclassification does not impact the compliance with any covenants of the related credit agreement with Wells Fargo. </p> <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The errors in the consolidated financial statements for each of the <span style="white-space:nowrap">Non-Reliance</span> Periods will be corrected in restated financial statements for each such period in amendments to the Company&#8217;s Quarterly Report on Form <span style="white-space:nowrap">10-Q</span> for the fiscal quarter ended September&#160;30, 2022, Annual Report on <span style="white-space:nowrap">Form&#160;10-K</span> for the fiscal year ended December&#160;31, 2022, and Quarterly Report on Form <span style="white-space:nowrap">10-Q</span> for the fiscal quarter ended March&#160;31, 2023. The Company is diligently pursuing completion of the restatements and intends to file such amendments prior to the filing of the Company&#8217;s Q2 Form <span style="white-space:nowrap">10-Q.</span> </p> <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In connection with the above restatements, as a result of the misclassification, the Company&#8217;s management has identified a material weakness in its internal control over financial reporting during the periods covered by such reports and has determined that its disclosure controls and procedures were also not effective as of September&#160;30, 2022 and all subsequent periods, which continues to be the case. </p> <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company&#8217;s management and the Audit Committee have discussed the matters disclosed in this Item 4.02 with the Company&#8217;s independent registered public accounting firm, PricewaterhouseCoopers LLP. </p> <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">To complete the restatements, the Company will file a Notification of Late Filing on Form <span style="white-space:nowrap">12b-25</span> with the Securities and Exchange Commission in order to obtain an additional five calendar days to file the Company&#8217;s Quarterly Report on Form <span style="white-space:nowrap">10-Q</span> for the fiscal quarter ended June&#160;30, 2023, which is expected to be filed on or before August&#160;14, 2023. </p>
