Item 2.02 Results of Operations and Financial Condition.

Updated Non-GAAP Financial Measures and Updated Investor Presentation

On May 20, 2025, ADTRAN Holdings, Inc. (the “Company”) filed with the Securities and Exchange Commission (the “SEC”) an Amendment No. 1 to its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the “Amended Form 10-K”), in which the Company restated its consolidated financial statements as of and for the fiscal years ended December 31, 2024 and 2023 and certain condensed consolidated financial information as of and for the interim periods ended March 31, 2024, June 30, 2024 and September 30, 2024 (such financial statements and information, collectively, the “Restated Financial Statements” and, such fiscal years and interim periods, collectively, the “Restatement Periods”). Additionally, on May 20, 2025, the Company filed with the SEC its Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 (“First Quarter 2025 Form 10-Q”) containing unaudited condensed consolidated financial statements of the Company as of and for the quarter ended March 31, 2025 (“Final Q1 2025 Financials”). The financial statements and information in the Amended Form 10-K and the First Quarter 2025 Form 10-Q supersede the preliminary financial information set forth in the Company’s press release dated May 7, 2025 and accompanying investor presentation that were attached as Exhibits 99.1 and 99.2, respectively, to the Company’s Current Report on Form 8-K furnished to the SEC on May 8, 2025.

This Current Report on Form 8-K is being furnished to provide (i) updated non-GAAP financial measures, with reconciliations to the most directly comparable GAAP financial measures, for each of the Restatement Periods and for the first quarter of 2025 (the “Non-GAAP Financial Information”), and (ii) an updated investor presentation giving effect to the Restated Financial Statements and the Final Q1 2025 Financials (the “Investor Presentation”). The Non-GAAP Financial Information and the Investor Presentation are attached hereto as Exhibit 99.1 and Exhibit 99.2, respectively, and are incorporated herein by reference.

Exhibit 99.1

Supplemental Non-GAAP Financial Measures

ADTRAN Holdings, Inc. (the “Company”) is providing the following tables to present certain non-GAAP information for the reporting periods covered in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2024 (the “Amended Form 10-K”) and the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 (the “First Quarter 2025 Form 10-Q”), each filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 20, 2025.

As previously reported, the Company filed the Amended Form 10-K in order to, among other items, restate the Company’s (i) audited consolidated financial statements as of and for the years ended December 31, 2024 (“Fiscal 2024”) and December 31, 2023 (“Fiscal 2023”) and (ii) unaudited condensed consolidated financial information as of and for the interim periods ended March 31, 2024, June 30, 2024 and September 30, 2024 (the “2024 Interim Periods”, collectively with Fiscal 2024 and Fiscal 2023, the “Affected Periods”). The First Quarter 2025 Form 10-Q also presented financial information for the quarter ended March 31, 2025 (“Q1 2025”) that superseded the preliminary financial information set forth in the Company’s press release dated May 7, 2025 and accompanying investor presentation that were attached as Exhibits 99.1 and 99.2, respectively, to the Company’s Current Report on Form 8-K furnished to the SEC on May 8, 2025.

In addition to results prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) presented in the Amended Form 10-K and the First Quarter 2025 Form 10-Q, the Company is providing this Supplement in order to present corrected non-GAAP measures and reconciliation tables for (i) non-GAAP gross profit, (ii) non-GAAP gross margin, (iii) non-GAAP operating expenses, (iv) non-GAAP operating income (loss), (v) non-GAAP operating margin, (vi) non-GAAP other expense, (vii) non-GAAP net income (loss) inclusive of the non-controlling interest, (viii) non-GAAP net income attributable to the non-controlling interest, (ix) non-GAAP net income (loss) attributable to the Company, (x) non-GAAP net earnings (loss) per share - basic and diluted, attributable to the Company, and (xi) free cash flow for each of the Affected Periods.

Set forth in the tables below are reconciliations of gross profit, gross margin, operating expenses, operating loss, operating margin, other expense, net loss inclusive of the non-controlling interest, net income attributable to the non-controlling interest, net loss attributable to the Company, and loss per share - basic and diluted, attributable to the Company, and net cash provided by operating activities, in each case as reported based on generally accepted accounting principles in the United States (“GAAP”), to non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income (loss), non-GAAP operating margin, non-GAAP other expense, non-GAAP net income (loss) inclusive of the non-controlling interest, non-GAAP net income attributable to the non-controlling interest, non-GAAP net income (loss) attributable to the Company, non-GAAP net earnings (loss) per share - basic and diluted, attributable to the Company, and free cash flow, respectively. Such non-GAAP measures exclude acquisition-related expenses, amortization and adjustments (consisting of intangible amortization of backlog, inventory fair value adjustments, developed technology, customer relationships, and trade names acquired in connection with business combinations, as well as legal and advisory fees related to a previously contemplated significant transaction, stock-based compensation expense, restructuring expenses, integration expenses, deferred compensation adjustments, goodwill impairments, amortization of pension actuarial losses, the tax effect of these adjustments to net loss and purchases of property, plant and equipment. These measures are used by management in our ongoing planning and annual budgeting processes. Additionally, we believe the presentation of these non-GAAP measures, when combined with the presentation of the most directly comparable GAAP financial measure, is beneficial to the overall understanding of the 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 measures may not be comparable to similar measures calculated by other companies.


 

 

The following tables present the reconciliation of gross profit and gross margin to non-GAAP gross profit and non-GAAP gross margin for the three months ended March 31, 2025 and 2024; the three months ended December 31, 2024 and the years ended December 31, 2024 and 2023; the three and six months ended June 30, 2024; and the three and nine months ended September 30, 2024.

(1) Includes intangible amortization of backlog, inventory fair value adjustments, developed technology, customer relationships, and trade names acquired in connection with business combinations. We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures. Such charges are significantly impacted by the timing and magnitude of our acquisitions. We exclude these charges for the purpose of calculating our non-GAAP measures, primarily because they are noncash expenses and our internal benchmarking analyses evidence that many industry participants and peers present non-GAAP financial measures excluding intangible asset amortization. Although this does not directly affect our cash position, the loss in value of intangible assets overtime can have a material impact on the equivalent GAAP earnings measure.

(2) Includes expenses for a Business Efficiency Program designed to optimize the assets and business processes following the business combination with Adtran Networks. Other than the Company's aim of selling its headquarters, the Business Efficiency Program was completed as of December 31, 2024.

(3) Includes expenses related to the Company's one-time integration bonus program in connection with synergy targets as a result of the business combination with Adtran Networks which was completed as of December 31, 2024.

The restructuring program commenced upon the closing of the business combination with Adtran Networks SE and was substantially completed in late 2024.

(1) Includes intangible amortization of backlog, inventory fair value adjustments, developed technology, customer relationships, and trade names acquired in connection with business combinations. We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures. Such charges are significantly impacted by the timing and magnitude of our acquisitions. We exclude these charges for the purpose of calculating our non-GAAP measures, primarily because they are noncash expenses and our internal benchmarking analyses evidence that many industry participants and peers present non-GAAP financial measures excluding intangible asset amortization. Although this does not directly affect our cash position, the loss in value of intangible assets over time can have a material impact on the equivalent GAAP earnings measure.

(2) Includes expenses for restructuring program designed to optimize the assets and business processes following the business combination with Adtran Networks SE. These expenses include inventory write down and other charges incurred as a result of a strategic shift in certain product lines in connection with the restructuring program.The restructuring program commenced upon the closing of the business combination with Adtran Networks SE and was substantially completed in late 2024. Additionally, as part of the Business Efficiency Program, management determined to close a facility in Greifswald, Germany which occurred in December 2024. Other than the Company's aim of selling its headquarters, the Business Efficiency Program was completed as of December 31, 2024.

(3) Includes expenses related to the Company's one-time integration bonus program in connection with synergy targets as a results of the business combination with Adtran Networks, which was completed as of December 31, 2024. Includes fees incurred for the expansion of internal controls at Adtran Networks and the implementation of the DPTLA.

(4) Includes non-cash change in fair value of equity investments held in the ADTRAN Holdings, Inc. Deferred Compensation Program for Employees, all of which is included in selling, general and administrative expenses on the condensed consolidated statement of loss.

(5) Non-cash impairment of goodwill in our Network Solutions reporting unit, necessitated by factors such as a decrease in the Company’s market capitalization, cautious service provider spending due to economic uncertainty and continued customer inventory adjustments.

(1) Loss per common share attributable to ADTRAN Holdings, Inc. - basic and diluted - reflects a $3 thousand effect of redemption for the three months ended March 31, 2025.

(2) Represents the non-controlling interest portion of the Company's ownership of Adtran Networks pre-DPLTA and the annual recurring compensation earned by redeemable non-controlling interests and accrued by the Company post-DPLTA.

(3) We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures.

(4) Includes non-cash change in fair value of equity investments held in deferred compensation plans offered to certain employees.

(5) Includes amortization of actuarial losses related to the Company's pension plan for employees in certain foreign countries.

(6) Includes expenses for a Business Efficiency Program designed to optimize the assets and business processes following the business combination with Adtran Networks. Other than the Company's aim of selling its headquarters, the Business Efficiency Program was completed as of December 31, 2024.

(7) Includes expenses related to the Company's one-time integration bonus program in connection with synergy targets as a results of the business combination with Adtran Networks. Includes fees incurred for the expansion of internal controls at Adtran Networks and the implementation of the DPTLA which was completed as of December 31, 2024.

(8) Represents the tax effect of non-GAAP adjustments. Beginning in the period ended September 30, 2024, the Company changed its method of calculating non-GAAP income taxes by applying blended statutory tax rates to non-GAAP income and losses before income taxes in order to include current and deferred income tax expenses that are commensurate with the non-GAAP measure of profitability. The blended statutory tax rate is calculated using 0%, resulting in no tax benefits net of impact of


valuation allowance, for the loss jurisdiction’s non-GAAP losses before income taxes, 24% for the loss jurisdiction's non-GAAP income before income taxes and 30% for all remaining jurisdictions’ non-GAAP income before income taxes. Prior periods have been adjusted to reflect the application of blended statutory tax rates, net of impact of valuation allowance, to non-GAAP losses before income taxes as opposed to the previous application of blended statutory and effective tax rates to separate non-GAAP adjustments. We previously reported the tax effect of the adjustment to non-GAAP net loss under the prior method of $5.6 million for the three months ended March 31, 2024.

(1) Represents the non-controlling interest portion of the Company's ownership of Adtran Networks pre-DPLTA and the annual recurring compensation earned by redeemable non-controlling interests and accrued by the Company post-DPLTA.

(2) Includes non-cash change in fair value of equity investments held in deferred compensation plans offered to certain employees.

(3) Includes amortization of actuarial losses related to the Company's pension plan for employees in certain foreign countries.

(4) Represents the tax effect of non-GAAP adjustments. Beginning in the period ending September 30, 2024, the Company changed its method of calculating non-GAAP income taxes by applying blended statutory tax rates to non-GAAP losses before income taxes in order to include current and deferred income tax expenses that are commensurate with the non-GAAP measure of profitability. The blended statutory tax rate is calculated using 0%, resulting in no tax benefits net of impact of valuation allowance, for the loss jurisdiction’s non-GAAP losses before income taxes and 30% for all remaining jurisdictions’ non-GAAP income before income taxes. Prior periods have been adjusted to reflect the application of blended statutory tax rates, net of impact of valuation allowance, to non-GAAP losses before income taxes as opposed to the previous application of blended statutory and effective tax rates to separate non-GAAP adjustments. We previously reported the tax effect of the adjustment to non-GAAP net loss under the prior method of $7.9 million and $13.5 million for the three and six months ended June 30, 2024, respectively.

Slide 21

GAAP to non-GAAP reconciliations


Slide 22

Non-GAAP cost of revenue, gross profit and gross margin reconciliation (1) Includes intangible amortization of backlog, inventory fair value adjustments, developed technology, customer relationships, and trade names acquired in connection with business combinations. We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures. Such charges are significantly impacted by the timing and magnitude of our acquisitions. We exclude these charges for the purpose of calculating our non-GAAP measures, primarily because they are noncash expenses and our internal benchmarking analyses evidence that many industry participants and peers present non-GAAP financial measures excluding intangible asset amortization. Although this does not directly affect our cash position, the loss in value of intangible assets over time can have a material impact on the equivalent GAAP earnings measure.  (2) Includes expenses for restructuring program designed to optimize the assets and business processes following the business combination with Adtran Networks SE. These expenses include inventory write down and other charges of $8.6 million and other expenses of $0.6 million for the twelve months ended December 31, 2024, incurred as a result of a strategy shift which included discontinuance of certain product lines in connection with the Business Efficiency Program. The restructuring program commenced upon the closing of the business combination with Adtran Networks SE and was substantially completed in late 2024. Additionally, as part of the Business Efficiency Program, management determined to close a facility in Greifswald, Germany which occurred in December 2024. These expenses include restructuring wage charges of $5.4 million for the twelve months ended December 31, 2024. (3) Includes expenses related to the Company's one-time integration bonus program in connection with synergy targets as a result of the business combination with Adtran Networks SE.

Non-GAAP operating expense reconciliation footnotes (1) We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures. Such charges are significantly impacted by the timing and magnitude of our acquisitions. We exclude these charges for the purpose of calculating our non-GAAP measures, primarily because they are non-cash expenses and our internal benchmarking analyses evidence that many industry participants and peers present non-GAAP financial measures excluding intangible asset amortization. Although this does not directly affect our cash position, the loss in value of intangible assets over time can have a material impact on the equivalent GAAP earnings measure. (2) Includes $2.2 million of intangible amortization of developed technology, customer relationships, and trade names acquired in connection with business combinations. (3) $2.0 million is included in selling, general and administrative expenses and $0.9 million is included in research and development expenses on the condensed consolidated statements of loss. (4) Other than the Company's aim of selling its headquarters, the Business Efficiency Program was completed as of December 31, 2024.

Non-GAAP operating income (loss) and operating margin reconciliation (1) Includes intangible amortization of backlog, inventory fair value adjustments, developed technology, customer relationships, and trade names acquired in connection with business combinations. We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures. Such charges are significantly impacted by the timing and magnitude of our acquisitions. We exclude these charges for the purpose of calculating our non-GAAP measures, primarily because they are noncash expenses and our internal benchmarking analyses evidence that many industry participants and peers present non-GAAP financial measures excluding intangible asset amortization. Although this does not directly affect our cash position, the loss in value of intangible assets over time can have a material impact on the equivalent GAAP earnings measure.  (2) Includes expenses for restructuring program designed to optimize the assets and business processes following the business combination with Adtran Networks SE. The restructuring program commenced upon the closing of the business combination with Adtran Networks SE and was substantially completed in late 2024.

Non-GAAP net income (loss) and earnings (loss) per share reconciliation (1) Loss per common share attributable to ADTRAN Holdings, Inc. - basic and diluted - reflects a $3 thousand and $5 thousand effect of redemption for the three months ended March 31, 2025 and December 31, 2024 respectively. (2) Represents the non-controlling interest portion of the Company's ownership of Adtran Networks pre-DPLTA and the annual recurring compensation earned by redeemable non-controlling interests and accrued by the Company post-DPLTA. (3) We incur charges relating to the amortization of intangible assets and exclude these charges for purposes of calculating our non-GAAP measures. Such charges are significantly impacted by the timing and magnitude of our acquisitions. We exclude these charges for the purpose of calculating our non-GAAP measures, primarily because they are non-cash expenses and our internal benchmarking analyses evidence that many industry participants and peers present non-GAAP financial measures excluding intangible asset amortization. Although this does not directly affect our cash position, the loss in value of intangible assets over time can have a material impact on the equivalent GAAP earnings measure.

Includes fees incurred for the expansion of internal controls at Adtran Networks and the implementation of the DPTLA which was completed as of December 31, 2024. (8) Represents the tax effect of non-GAAP adjustments. Beginning in the period ended September 30, 2024, the Company changed its method of calculating non-GAAP income taxes by applying blended statutory tax rates to non-GAAP losses before income taxes in order to include current and deferred income tax expenses that are commensurate with the non-GAAP measure of profitability. The blended statutory tax rate is calculated using 0%, resulting in no tax benefits net of impact of valuation allowance, for the loss jurisdiction’s non-GAAP losses before income taxes and 30% for all remaining jurisdictions’ non-GAAP income before income taxes. Prior periods have been adjusted to reflect the application of blended statutory tax rates, net of impact of valuation allowance, to non-GAAP losses before income taxes as opposed to the previous application of blended statutory and effective tax rates to separate non-GAAP adjustments. We previously reported the tax effect of the adjustment to non-GAAP net loss under the prior method of $5.6 million for the three months ended March 31, 2024.

Explanation of use of non-GAAP financial measures Set forth in the tables above are reconciliations of gross profit, gross margin, operating expenses, operating loss, operating margin, other expense, net loss inclusive of the non-controlling interest, net income attributable to the non-controlling interest, net loss attributable to the Company, and loss per share - basic and diluted, attributable to the Company, and net cash provided by operating activities, in each case as reported based on generally accepted accounting principles in the United States (“GAAP”), to non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income (loss), non-GAAP operating margin, non-GAAP other expense, non-GAAP net income (loss) inclusive of the non-controlling interest, non-GAAP net income attributable to the non-controlling interest, non-GAAP net income (loss) attributable to the Company, non-GAAP net earnings (loss) per share - basic and diluted, attributable to the Company, and free cash flow, respectively. Such non-GAAP measures exclude acquisition-related expenses, amortization and adjustments (consisting of intangible amortization of backlog, inventory fair value adjustments, developed technology, customer relationships, and trade names acquired in connection with business combinations, as well as legal and advisory fees related to a previously contemplated significant transaction, stock-based compensation expense, restructuring expenses, integration expenses, deferred compensation adjustments, goodwill impairments, amortization of pension actuarial losses, the tax effect of these adjustments to net loss and purchases of property, plant and equipment. These measures are used by management in our ongoing planning and annual budgeting processes. Additionally, we believe the presentation of these non-GAAP measures, when combined with the presentation of the most directly comparable GAAP financial measure, is beneficial to the overall understanding of the 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 measures may not be comparable to similar measures calculated by other companies. Non-GAAP operating margin (which is calculated as non-GAAP operating income (loss) divided by revenue) is a non-GAAP financial measure. The Company has provided second quarter 2025 guidance with regard to non-GAAP operating margin. This measure excludes from the corresponding GAAP financial measure the effect of adjustments as described below. The Company has not provided a reconciliation of such non-GAAP guidance to guidance presented on a GAAP basis because it cannot predict and quantify without unreasonable effort all of the adjustments that may occur during the period due to the difficulty of predicting the timing and amounts of various items within a reasonable range. In particular, non-GAAP operating margin excludes certain items, such as acquisition related expenses, amortizations and adjustments, stock-based compensation expense, restructuring expenses, integration expenses, deferred compensation adjustments, and goodwill impairment that the Company is unable to quantitatively predict. Depending on the materiality of these items, they could have a significant impact on the Company's GAAP financial results.
