ADTRAN Holdings, Inc. (NASDAQ:ADTN) ("ADTRAN Holdings" or the "Company") today announced its unaudited financial results for the second quarter of 2024.

Revenue: $226.0 million
Gross margin:
- GAAP gross margin: 36.1%; Non-GAAP gross margin: 41.9%
Operating margin:
- GAAP operating margin negative 17.0%; Non-GAAP operating margin positive 0.7%
Net Income (Loss):
- GAAP net loss attributable to the Company: $49.9 million; Non-GAAP net loss attributable to the Company: $18.8 million
Earnings (Loss) per share:
- GAAP diluted loss per share attributable to the Company: $0.63; Non-GAAP diluted loss per share attributable to the Company: $0.24.

ADTRAN Holdings' Chairman and Chief Executive Officer Tom Stanton stated, "We had a solid second quarter, during which we saw improvements across all our major operating metrics, including profitability and working capital. During the quarter, we saw growth in our customer base across the U.S. and Europe as customers continue to adopt our latest fiber networking solutions".

For the third quarter of 2024, the Company expects revenue in a range of $215million to $235million. Non-GAAP operating margin is expected in a range of -1% to +3%.

Furthermore, non-GAAP operating margin (which is calculated as non-GAAP operating loss divided by revenue) is a non-GAAP financial measure. The Company has provided third quarter 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, including continued restructuring and integration expenses that will continue to evolve as our business efficiency program is implemented, 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.

The Company will hold a conference call to discuss its second quarter results on Tuesday, August 06, 2024, at 9:30 a.m. Central Time, or 4:30 p.m. Central European Summer Time. The Company will webcast this conference call. To listen, simply visit our Investor Relations site at investors.adtran.com approximately 10 minutes prior to the start of the call, click on the event "ADTRAN Holdings Releases 2^nd Quarter 2024 Financial Results and Earnings Call", and click on the webcast link.

Cautionary Note Regarding Forward-Looking Statements

Statements contained in this press release which are not historical facts, such as those relating to expectations regarding future revenues; ADTRAN Holdings ability to reduce its inventory levels; ADTRAN Holdings' potential funding opportunities; and ADTRAN Holdings' strategy and outlook, outlook and financial guidance, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements can also generally be identified by the use of words such as "believe," "expect," "intend," "estimate," "anticipate," "will," "may," "could" and similar expressions. In addition, ADTRAN Holdings, through its senior management, may from time to time make forward-looking public statements concerning the matters described herein. All such projections and other forward-looking information speak only as of the date hereof, and ADTRAN Holdings undertakes no duty to publicly update or revise such forward-looking information, whether as a result of new information, future events, or otherwise, except to the extent as may be required by law. All such forward-looking statements are necessarily estimates and reflect management's best judgment based upon current information. Actual events or results may differ materially from those anticipated in these forward-looking statements as a result of a variety of factors. While it is impossible to identify all such factors, factors which have caused and may in the future cause actual events or results to differ materially from those estimated by ADTRAN Holdings include, but are not limited to: (i) risks and uncertainties relating to ADTRAN Holdings' ability to continue to reduce expenditures and the impact of such reductions on its financial results and financial condition; (ii) the risk of fluctuations in revenue due to lengthy sales and approval processes required by major and other service providers for new products, as well as ongoing tighter inventory management of ADTRAN Holdings' customers ; (iii) risks and uncertainties relating to ongoing material weaknesses in our internal control over financial reporting; (iv) our ability to comply with the covenants set forth in our credit facility; (v) risks posed by potential breaches of information systems and cyber-attacks; (vi) the risk that ADTRAN Holdings may not be able to effectively compete, including through product improvements and development; and (vii) other risks set forth in ADTRAN Holdings' public filings made with the Securities and Exchange Commission ("SEC"), including its Annual Report on Form 10-K for the year ended December 31, 2023, its Quarterly Report on Form 10-Q for the first quarter ended March 31, 2024, and risks to be disclosed in its Form 10-Q for the quarterly period ended March 31, 2024.

Explanation of Use of Non-GAAP Financial Measures

Set forth in the tables below are reconciliations of gross profit, gross margin, operating expenses, operating loss, other (expense) income, net loss inclusive of the non-controlling interest, net loss attributable to the Company, net income attributable to the non-controlling interest, and loss per share - basic and diluted, attributable to the Company, and net cash provided by (used in) 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 other expense, non-GAAP net loss inclusive of the non-controlling interest, non-GAAP net loss attributable to the Company, non-GAAP net income attributable to the non-controlling interest, non-GAAP loss per share - basic and diluted, attributable to the Company, respectively, and non-GAAP free cash flow. Such non-GAAP measures exclude acquisition-related expenses, amortization and adjustments (consisting of intangible amortization of backlog, developed technology, customer relationships, and trade names acquired in connection with business combinations and amortization of inventory fair value adjustments as well as legal and advisory fees related to a potential significant transaction), stock-based compensation expense, amortization of pension actuarial losses, deferred compensation adjustments, integration expenses, restructuring expenses, goodwill impairments, 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 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.
