GENERAL

On July 8, 2022, Acorn MergeCo, Inc. (“Merger Sub”), a Delaware corporation and wholly-owned direct subsidiary of ADTRAN Holdings, Inc. (f/k/a Acorn HoldCo), merged with and into ADTRAN, Inc., with ADTRAN, Inc. surviving the merger as a wholly-owned direct subsidiary of ADTRAN Holdings, Inc. (the “Merger”). The Merger was consummated pursuant to the Business Combination Agreement, dated as of August 30, 2021 (the “Business Combination Agreement”), by and among ADTRAN Holdings, Inc., ADTRAN, Inc., ADVA Optical Networking SE, a company organized and existing under the laws of Germany (“ADVA”), and Merger Sub. In accordance with the Business Combination Agreement, ADTRAN Holdings, Inc. made a public offer to exchange each issued and outstanding no-par value bearer share of ADVA for 0.8244 shares of common stock, par value $0.01 per share (the “Company Common Stock”), of ADTRAN Holdings, Inc. (the “Exchange Offer” and, together with the Merger, the “Business Combination”). On July 15, 2022 (the “Exchange Offer Settlement Date”), ADTRAN Holdings, Inc. completed the Exchange Offer, in which ADTRAN Holdings, Inc. acquired 33,957,538 bearer shares of ADVA, or 65.43% of ADVA’s outstanding bearer shares as of the Exchange Offer Settlement Date, in exchange for the issuance of an aggregate of 27,994,595 shares of common stock of ADTRAN Holdings, Inc.

Unless the context otherwise indicates or requires, references in this Quarterly Report on Form 10-Q to “ADTRAN,” the “Company,” “we,” “us” and “our” refer to ADTRAN, Inc. and its consolidated affiliates prior to the Merger on July 8, 2022, and to ADTRAN Holdings, Inc. and its consolidated subsidiaries following the Merger.

This Quarterly Report on Form 10-Q relates to the Company’s quarter ended June 30, 2022, which was prior to the completion of the Business Combination.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements made by or on behalf of ADTRAN. ADTRAN and its representatives may from time to time make written or oral forward-looking statements, including statements contained in this report, our other filings with the Securities and Exchange Commission (the “SEC”) and other communications with our stockholders. Any statement that does not directly relate to a historical or current fact is a forward-looking statement. Generally, the words, “believe”, “expect”, “intend”, “estimate”, “anticipate”, “will”, “may”, “could” and similar expressions identify forward-looking statements. We caution you that any forward-looking statements made by us or on our behalf are subject to uncertainties and other factors that could affect the accuracy of such statements. The following are some of the risks that could affect our financial performance or could cause actual results to differ materially from those expressed or implied in our forward-looking statements:

Risks related to the Business Combination

•

We may fail to realize the anticipated strategic and financial benefits sought from the Business Combination.

•

We may experience operational challenges, negative synergies and loss of customers.

•

While we intend to enter into a DPLTA with ADVA, we may not be successful in doing so or the effectiveness of a DPLTA may be delayed as a result of litigation or otherwise, which may have an adverse effect on the ability to realize synergies and cost reductions and the market value of our shares.

•

We may enter into a DPLTA with ADVA, which may have a material adverse effect on our financial results and condition.

•

We are exposed to additional litigation risk and uncertainty with respect to the remaining minority shareholders of ADVA.

•

Negative publicity related to post-closing integration measures, may adversely affect us.

•

We have incurred and expect to continue to incur significant transaction fees and costs in connection with the Business Combination and post-closing integration efforts.

•

We incurred a substantial amount of indebtedness in connection with the Business Combination. Our failure to meet our debt service obligations could have a material adverse effect on our business, financial condition and results of operations.

•

Risks relating to the business of ADVA may have a significant adverse impact on our business and financial performance.

•

We may be unable to successfully retain and motivate our personnel, including personnel at ADVA.

•

The terms of the credit agreement restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.

•

In addition to the acquisition of a majority equity stake in ADVA, we may be unable to successfully and effectively manage and integrate acquisitions, divestitures and other significant transactions, which could harm our operating results, business and prospects.

Risks related to our financial results and Company success

•

Our revenue for a particular period can be difficult to predict, and a shortfall in revenue may harm our operating results.

•

The lengthy sales and approval process required by service providers for new products could result in fluctuations in our revenue.

•

We depend heavily on sales to certain customers; the loss of any of these customers would significantly reduce our revenue and net income.

•

Our exposure to the credit risks of our customers and distributors may make it difficult to collect accounts receivable and could adversely affect our operating results, financial condition and cash flows.

•

We expect gross margins to vary over time, and our levels of product and services gross margins may not be sustainable.

•

Our strategy of outsourcing a portion of our manufacturing requirements to subcontractors located in various international regions may result in us not meeting our cost, quality or performance standards.

•

Our dependence on a limited number of suppliers for certain raw materials, key components and ODM products, combined with supply shortages, have prevented and may continue to prevent us from delivering our products on a timely basis, which has had and may continue to have a material adverse effect on operating results and could have a material adverse effect on customer relations.

•

We compete in markets that have become increasingly competitive, which may result in reduced gross profit margins and market share.

•

Our estimates regarding future warranty obligations may change due to product failure rates, installation and shipment volumes, field service repair obligations and other rework costs incurred in correcting product failures. If our estimates change, our liability for warranty obligations may increase or decrease, impacting future cost of revenue.

•

Managing our inventory is complex and may include write-downs of excess or obsolete inventory.

•

The continuing growth of our international operations could expose us to additional risks, increase our costs and adversely affect our operating results, financial condition and cash flows.

•

Our success depends on attracting and retaining key personnel.

•

If we fail to manage our exposure to worldwide financial and securities markets successfully, our operating results and financial statements could be materially impacted.

•

The terms of the credit agreement governing our senior credit facility restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.

•

We are exposed to adverse currency exchange rate fluctuations in jurisdictions where we transact in local currency, which could harm our financial results and cash flows.

Risks related to COVID-19

•

The ongoing COVID-19 pandemic has impacted and may continue to impact our business, results of operations and financial condition, particularly our supply chain and workforce.

Risks related to our control environment

•

We are currently in the process of implementing a new enterprise resource planning ("ERP") software solution. If we do not effectively implement this project, or any future associated updates, our operations could be significantly disrupted.

•

Breaches of our information systems and cyber-attacks could compromise our intellectual property and cause significant damage to our business and reputation.

•

If we fail to maintain proper and effective internal controls over financial reporting we could have a material weakness in those internal controls, that if not remediated, could materially adversely affect us.

Risks related to the telecommunications industry

•

We must continue to update and improve our products and develop new products to compete and to keep pace with improvements in communications technology.

•

Our failure or the failure of our contract manufacturers to comply with applicable environmental regulations could adversely impact our results of operations.

•

If our products do not interoperate with our customers’ networks, installations may be delayed or canceled, which could harm our business.

•

We engage in research and development activities to develop new, innovative solutions and to improve the application of developed technologies, and as a consequence may miss certain market opportunities enjoyed by larger companies with substantially greater research and development efforts and which may focus on more leading edge development.

•

Our failure to maintain rights to intellectual property used in our business could adversely affect the development, functionality and commercial value of our products.

•

Software under license from third parties for use in certain of our products may not continue to be available to us on commercially reasonable terms.

•

Our use of open source software could impose limitations on our ability to commercialize our products.

•

We may incur liabilities or become subject to litigation that would have a material effect on our business.

•

If we are unable to successfully develop and maintain relationships with SIs, service providers and enterprise VARs, our revenue may be negatively affected.

Risks related to the regulatory environments in which we do business

•

We are subject to complex and evolving U.S. and foreign laws, regulations and standards governing the conduct of our business. Violations of these laws and regulations may harm our business, subject us to penalties and to other adverse consequences.

•

Changes in trade policy in the U.S. and other countries, specifically the U.K. and China, including the imposition of additional tariffs and the resulting consequences, may adversely impact our gross profits, gross margins, results of operations and financial condition.

•

New or revised tax regulations, changes in our effective tax rate, recognition of a valuation allowance or assessments arising from tax audits may have an adverse impact on our results.

The foregoing list of risks is not exclusive. For a more detailed description of the risk factors associated with our business, see Part I, Item 1A of the ADTRAN, Inc. Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 25, 2022 (the “2021 Form 10-K”), as well as the risk factors set forth in Part II, Item 1A of this Quarterly Report on Form 10-Q. We caution investors that other factors may prove to be important in the future in affecting our operating results. New factors emerge from time to time, and it is not possible for us to predict all of these factors, nor can we assess the impact each factor, or a combination of factors, may have on our business.

You are further cautioned not to place undue reliance on these forward-looking statements because they speak only of our views as of the date that the statements were made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

(Unaudited)

On July 8, 2022, Acorn MergeCo, Inc. (“Merger Sub”), a Delaware corporation and wholly-owned direct subsidiary of ADTRAN Holdings, Inc. (formerly known as Acorn HoldCo), merged with and into ADTRAN, Inc., with ADTRAN, Inc. surviving the merger as a wholly-owned direct subsidiary of ADTRAN Holdings, Inc. (the “Merger”). The Merger was consummated pursuant to the Business Combination Agreement, dated as of August 30, 2021 (the “Business Combination Agreement”), by and among ADTRAN Holdings, Inc., ADTRAN, Inc., ADVA Optical Networking SE, a company organized and existing under the laws of Germany (“ADVA”), and Merger Sub. In accordance with the Business Combination Agreement, ADTRAN Holdings, Inc. made a public offer to exchange each issued and outstanding no-par value bearer share of ADVA for 0.8244 shares of common stock, par value $0.01 per share (the “Company Common Stock”), of ADTRAN Holdings, Inc. (the “Exchange Offer” and, together with the Merger, the “Business Combination”). On July 15, 2022 (the “Exchange Offer Settlement Date”), ADTRAN Holdings, Inc. completed the Exchange Offer, in which ADTRAN Holdings, Inc. acquired 33,957,538 bearer shares of ADVA, or 65.43% of ADVA’s outstanding bearer shares as of the Exchange Offer Settlement Date, in exchange for the issuance of an aggregate of 27,994,595 shares of common stock of ADTRAN Holdings, Inc.

Except as otherwise indicated, references in these notes to “ADTRAN,” the “Company,” “we,” “us” and “our” for time periods at and before the effectiveness of the Merger, including all fiscal periods ended on or prior to June 30, 2022, shall be deemed to refer to ADTRAN, Inc. as the predecessor registrant to ADTRAN Holdings, Inc.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of ADTRAN and its subsidiaries have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information presented in Quarterly Reports on Form 10-Q. Accordingly, certain information and notes required by generally accepted accounting principles in the United States of America (“U.S. GAAP”) for complete financial statements are not included herein. Certain prior year amounts have been reclassified to conform to the current period presentation. The December 31, 2021 Condensed Consolidated Balance Sheet is derived from audited financial statements but does not include all disclosures required by U.S. GAAP.

In the opinion of management, all adjustments necessary to fairly state these interim statements have been recorded and are of a normal and recurring nature. The results of operations for an interim period are not necessarily indicative of the results for the full year. The interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in ADTRAN, Inc. Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 25, 2022.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Significant estimates include excess and obsolete inventory reserves, warranty reserves, customer rebates, determination and accrual of the deferred revenue related to performance obligations under contracts with customers, estimated costs to complete obligations associated with deferred and accrued revenues and network installations, estimated income tax provision and income tax contingencies, fair value of stock-based compensation, assessment of goodwill and other intangibles for impairment, estimated lives of intangible assets, estimated pension liability and fair value of investments. Actual amounts could differ significantly from these estimates.

We assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to us and the unknown future impacts of the SARS-CoV-2 coronavirus/COVID-19 global pandemic (or variants of the SARS-CoV-2 coronavirus) as well as supply chain constraints as of June 30, 2022 and through the date of this report. The accounting matters assessed included, but were not limited to, the allowance for credit losses, stock-based compensation, carrying value of goodwill, intangibles and other long-lived assets, financial assets, valuation allowances for tax assets, revenue recognition and costs of revenue. Future conditions related to the magnitude and duration of the COVID-19 pandemic, as well as other factors, including supply chain constraints, could result in further impacts to our consolidated financial statements in future reporting periods.

Recently Adopted Accounting Pronouncements

There are currently no recently adopted accounting pronouncements that had a material effect on the condensed consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2021-08, Business Combinations (Topic 805) Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which would require an acquirer to recognize and measure acquired contract assets and contract liabilities in a manner consistent with how the acquiree recognized and measured them in its pre-acquisition financial statements in accordance with Topic 606, Revenue Recognition. ASU 2021-08 is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years. Adoption of the ASU should be applied prospectively. Early adoption is also permitted, including adoption in an interim period. If early adopted, the amendments are applied retrospectively to all business combinations for which the acquisition date occurred during the fiscal year of adoption. Given that the Business Combination with ADVA was finalized in July 2022, the Company plans to early adopt ASU 2021-08 during the third quarter of 2022. ASU 2021-08 will be effective as of January 1, 2022 and will be applied on a prospective basis. However, we are unable to estimate the effect on our Condensed Consolidated Financial Statements as of the date of this report.

The aggregate amount of transaction price allocated to remaining performance obligations that have not been satisfied as of June 30, 2022 and December 31, 2021 related to contractual maintenance agreements, contractual SaaS and subscription services, and hardware contracts that exceed one year in duration amounted to $164.5 million and $101.1 million, respectively. As of June 30, 2022, approximately 84% is expected to be recognized over the next 12 months and the remainder recognized thereafter. The majority of the Company's remaining performance obligations at June 30, 2022 are related to contracts or orders that have an original expected duration of one year or less, for which the Company is electing to utilize the practical expedient available within the guidance, and are excluded from the transaction price related to these future obligations. The Company will generally satisfy the remaining performance obligations as we transfer control of the products ordered or services to our customers, excluding maintenance services, which are satisfied over time.

The following table provides information about receivables, contract assets and unearned revenue from contracts with customers:


	As of		As of
(In thousands)	June 30, 2022		December 31, 2021
Accounts receivable, net	$	172,088	$	158,742
Contract assets(1)	$	1,749	$	464
Unearned revenue	$	22,705	$	17,737
Non-current unearned revenue	$	10,133	$	9,271

(1) Included in other receivables on the Condensed Consolidated Balance Sheets.

Of the outstanding unearned revenue balances as of December 31, 2021, $4.1 million and $9.5 million was recognized as revenue during the three and six months ended June 30, 2022, respectively. Of the $14.1 million of outstanding unearned revenue balances as of December 31, 2020, $2.9 million and $7.9 million was recognized as revenue during the three and six months ended June 30, 2021, respectively.

4. INCOME TAXES

Our effective tax rate changed from an expense of 18.1% of pre-tax income for the three months ended June 30, 2021, to an expense of 50.1% of pre-tax income for the three months ended June 30, 2022 and changed from an expense of 26.7% of pre-tax income for the six months ended June 30, 2021, to a benefit of 34.3% of pre-tax income for the six months ended June 30, 2022. The change in the effective tax rate for the three and six months ended June 30, 2022, was driven primarily by a change in our annual estimated tax rate as a result of the requirement to begin capitalizing research and development expenses for U.S. tax purposes beginning in 2022 as previously passed as part of the Tax Cuts and Jobs Act in December 2017 and the associated impact of those changes on our previously established valuation allowance.

The Company continually reviews the adequacy of its valuation allowance and recognizes the benefits of deferred tax assets only as the assessment indicates that it is more likely than not that the deferred tax assets will be recognized in accordance with ASC 740, Income Taxes. As of June 30, 2022, the Company had deferred tax assets totaling $71.4 million, and a valuation allowance totaling $62.9 million against those deferred tax assets. The remaining $8.5 million in deferred tax assets not offset by a valuation allowance are located in various foreign jurisdictions where the Company believes it is more likely than not we will realize these deferred tax assets. During the six months ended June 30, 2022, the total change in the valuation allowance against our domestic and international deferred tax assets was recorded in the amount of an $12.6 million increase and a $0.2 million decrease, respectively. Our assessment of the realizability of our deferred tax assets includes the evaluation of historical operating results as well as the evaluation of evidence which requires significant judgment, including the evaluation of our three-year cumulative income position, future taxable income projections and tax planning strategies. Should management’s conclusion change in the future and an additional valuation allowance or a partial or full release of the valuation allowance becomes necessary, it may have a material effect on our consolidated financial statements.

Supplemental balance sheet information related to deferred tax assets is as follows:


	As of June 30, 2022
(In thousands)	Deferred Tax Assets		Valuation Allowance			Deferred Tax Assets, net
Domestic	$	60,873	$	(60,873	)	$	—

5. STOCK-BASED COMPENSATION

The following table summarizes stock-based compensation expense related to stock options, performance stock units (“PSUs”), restricted stock units (“RSUs”) and restricted stock:


	Three Months Ended						Six Months Ended

Total stock-based compensation expense, net of tax	$	1,416		$	1,356		$	2,836		$	2,732

PSUs, RSUs and Restricted Stock

The following table summarizes PSUs, RSUs and restricted stock outstanding as of December 31, 2021 and June 30, 2022 and the changes that occurred during the six months ended June 30, 2022:


	Number of Shares (in thousands)			Weighted Avg. Grant Date Fair Value (per share)
Unvested PSUs, RSUs and restricted stock outstanding, December 31, 2021		1,930		$	14.11
PSUs, RSUs and restricted stock granted		336		$	20.14
PSUs, RSUs and restricted stock vested		(15	)	$	13.26
PSUs, RSUs and restricted stock forfeited		(41	)	$	14.08
Unvested PSUs, RSUs and restricted stock outstanding, June 30, 2022		2,210		$	15.04

During each of the six months ended June 30, 2022 and 2021, the Company granted 0.3 million performance-based PSUs to its executive officers and certain employees. The grant-date fair value of these performance-based awards was based on the closing price of the Company’s stock on the date of grant. These awards vest over one-year, two-year and three-year periods, respectively, subject to the grantee’s continued employment, with the ability to earn shares in a range of 0% to 142.8% of the awarded number of PSUs based on the achievement of defined performance targets. Equity-based compensation expense with respect to these awards may be adjusted over the vesting period to reflect the probability of achievement of performance targets defined in the award agreements.

The fair value of RSUs and restricted stock is equal to the closing price of our stock on the date of grant. The fair value of PSUs with market conditions is calculated using a Monte Carlo simulation valuation method.

As of June 30, 2022, total unrecognized compensation expense related to non-vested market-based PSUs, RSUs and restricted stock was approximately $13.9 million, which will be recognized over the remaining weighted-average period of 2.5 years. Pursuant to the Business Combination, which was closed on July 15, 2022, 0.3 million of market-based PSUs were converted to time-based RSUs which will be treated as an award modification under U.S. GAAP in the third quarter of 2022. This will result in incremental compensation expense of $1.6 million which will be recognized over the remaining weighted-average period of 1.1 years. In addition, there was $13.2 million of unrecognized compensation expense related to unvested 2020, 2021 and 2022 performance-based PSUs, which will be recognized over the remaining requisite service period of 0.5 years if achievement of the performance obligation becomes probable. Pursuant to the Business Combination, which was closed on July 15, 2022, the unearned performance-based PSUs were converted to time-based RSUs which will be treated as an award modification under U.S. GAAP in the third quarter of 2022. This will result in incremental compensation and unrecognized compensation expense totaling $17.8 million, which will be recognized over the remaining service period of 0.5 years. Unrecognized compensation expense will be adjusted for actual forfeitures.

As of June 30, 2022, 3.5 million shares were available for issuance under stockholder-approved equity plans.

Stock Options

The following table summarizes stock options outstanding as of December 31, 2021 and June 30, 2022 and the changes that occurred during the six months ended June 30, 2022:


	Number of Stock Options (in thousands)			Weighted Avg. Exercise Price (per share)		Weighted Avg. Remaining Contractual Life (in years)		Aggregate Intrinsic Value (in thousands)
Stock options outstanding, December 31, 2021		1,721		$	19.37		2.4	$	6,669
Stock options exercised		(37	)	$	17.24			$	110
Stock options expired		(23	)	$	23.67			$	5
Stock options outstanding, June 30, 2022		1,661		$	19.36		1.9	$	1,127
Stock options exercisable, June 30, 2022		1,661		$	19.36		1.9	$	1,127

As of June 30, 2022, there was no unrecognized compensation expense related to stock options as all awards vested in prior periods.

There were no stock options granted during the six months ended June 30, 2022 and 2021. All of the options were previously issued at exercise prices that approximated fair market value at the date of grant.

The aggregate intrinsic value of stock options represents the total pre-tax intrinsic value (the difference between ADTRAN’s closing stock price on the last trading day of the quarter and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on June 30, 2022. The amount of aggregate intrinsic value was $1.1 million as of June 30, 2022 and will change based on the fair market value of ADTRAN’s stock. The total pre-tax intrinsic value of options exercised during the six months ended June 30, 2022 was $0.1 million.

Realized gains and losses on sales of debt securities are computed under the specific identification method. The following table presents the gross realized gains and losses related to our debt securities:


	Three Months Ended						Six Months Ended

Total (loss) gain recognized, net	$	(85	)	$	77		$	(113	)	$	148

Income generated from available-for-sale debt securities was recorded as interest and dividend income in the Condensed Consolidated Statements of Income. No allowance for credit losses was recorded for the six months ended June 30, 2022 and 2021 related to available-for-sale debt securities. The Company’s investment policy provides limitations for issuer concentration, which limits, at the time of purchase, the concentration in any one issuer to 5% of the market value of our total investment portfolio. The Company did not purchase any available-for-sale debt security with credit deterioration during the six months ended June 30, 2022.

Marketable Equity Securities

Our marketable equity securities consist of publicly traded stock, interests in funds and certain other investments measured at fair value or cost (where appropriate).

The Company has an equity investment which does not have a readily determinable fair value and is recorded using the measurement alternative. Under the measurement alternative, equity investments that do not have a readily determinable fair value can be recorded at cost less impairment, if any, adjusted for observable price changes for an identical or similar investment. The carrying value of the equity investment as of June 30, 2022 and December 31, 2021 was $1.0 million. During the year ended December 31, 2021, impairment charges totaling $0.4 million, were recorded related to the equity investment. As of June 30 2022, cumulative impairment charges totaling $2.4 million were recorded related to the equity investment. There were no impairment charges during the three and six months ended June 30, 2022 and 2021. During the year ended December 31, 2021, an unsecured loan totaling $0.5 million was converted to equity which increased the Company's carrying value of the equity investment.

The Company has a secured note receivable as of June 30, 2022 and December 31, 2021 which totaled $0.4 million and is included in long term investments on the Consolidated Balance Sheets. During the year ended December 31, 2021, an impairment charge of $0.5 million was recognized against the secured note receivable. There were no impairment charges during the three and six months ended June 30, 2022 and 2021.

Realized and unrealized gains and losses related to marketable equity securities were as follows:

Total (loss) gain recognized, net	$	(4,561	)	$	1,932		$	(7,948	)	$	2,857

Income generated from marketable equity securities was recorded as interest and dividend income in the Condensed Consolidated Statements of Income. U.S. GAAP establishes a three-level valuation hierarchy based upon observable and unobservable inputs for fair value measurement of financial instruments:

• Level 1 – Observable outputs; values based on unadjusted quoted prices for identical assets or liabilities in an active market;

• Level 2 – Significant inputs that are observable; values based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly;

• Level 3 – Significant unobservable inputs; values based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs could include information supplied by investees.

The Company’s cash equivalents and investments held at fair value are categorized into this hierarchy as follows:


			Fair Value Measurements as of June 30, 2022 Using

Long-lived assets used in operations are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable and the undiscounted cash flows estimated to be generated by the asset are less than the asset’s carrying value. No impairment charges were recognized during the three and six months ended June 30, 2022 and 2021.

Depreciation expense was $2.7 million and $3.0 million for the three months ended June 30, 2022 and 2021 and $5.5 million and $6.1 million for the six months ended June 30, 2022 and 2021, respectively, which is recorded in cost of revenue, selling, general and administrative expenses and research and development expenses in the Condensed Consolidated Statements of Income.

Goodwill was $7.0 million as of June 30, 2022 and December 31, 2021, of which $6.6 million and $0.4 million was allocated to our Network Solutions and Services & Support reportable segments, respectively.

Goodwill represents the excess purchase price over the fair value of net assets acquired. We qualitatively assess the carrying value of goodwill each reporting period for events or circumstance changes that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Based on our assessment of certain qualitative factors such as macro-economic conditions, industry and market considerations, costs factors and overall financial performance, management concluded that no such events or circumstance changes were identified that would suggest that the fair value of the goodwill was more likely than not greater than its carrying amount as of June 30, 2022. No impairment of goodwill was recorded during the three and six months ended June 30, 2022 and 2021.

The Company evaluates the carrying value of intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable and the undiscounted cash flows estimated to be generated by the asset are less than the asset’s carrying value. Due to the current economic environment, particularly related to COVID-19, the Company assessed impairment triggers related to intangible assets during the first and second quarters of 2022 and 2021. As a result, no quantitative impairment test of long-lived assets was performed as of June 30, 2022 and 2021, and no impairment losses of intangible assets were recorded during the three and six months ended June 30, 2022 and 2021.

12. REVOLVING CREDIT AGREEMENTS

Cadence Revolving Credit Agreement

On May 19, 2022, the Company, as borrower, modified its Revolving Credit and Security Agreement and related Promissory Note (together, the “Cadence Revolving Credit Agreement”) with Cadence Bank, N.A., as lender (the “Cadence Lender”). The modified Cadence Revolving Credit Agreement provides the Company with a $25.0 million secured revolving credit facility. Loans under the Cadence Revolving Credit Agreement will bear interest at a rate equal to 1.50% over the screen rate as obtained by Reuter’s, Bloomberg or another commercially available source as may be designated by the Cadence Lender from time to time; provided, however, that in no event shall the applicable rate of interest under the Cadence Revolving Credit Agreement be less than 1.50% per annum. Such loans are secured by all of the cash, securities, securities entitlements and investment property in a certain bank account, as outlined in the Cadence Revolving Credit Agreement, at a maximum loan-to-value ratio of 85% determined by dividing the full commitment amount under the Cadence Revolving Credit Agreement on the date of testing, determined by the Cadence Lender each fiscal quarter, by the market value of the collateral. The Cadence Revolving Credit Agreement matures on November 3, 2022, subject to earlier termination upon the concurrence of certain events of default. The Company entered into the Cadence Revolving Credit Agreement in order to increase the flexibility and management of its short-term liquidity. During the first half of 2022, the Company made draws totaling $18.0 million under the Cadence Revolving Credit Agreement all of which had been repaid as of June 30, 2022. The Company agreed to certain negative covenants that are customary for credit arrangements of this type, including, among other things, restrictions on the Company’s ability to enter into mergers, acquisitions or other business combination transactions, grant liens or suffer a material adverse change in the condition or affairs (financial or otherwise) of the Company. As of June 30, 2022, the Company was in compliance with all contractual requirements under the Cadence Revolving Credit Agreement.

Wells Fargo Revolving Credit Agreement

On April 1, 2022, the Company entered into a Credit Agreement and related Revolving Line of Credit Note (together, the “Wells Revolving Credit Agreement”) in favor of Wells Fargo Bank, National Association, as lender (the “Wells Lender”). The Wells Revolving Credit Agreement provides the Company with a new $25.0 million secured revolving credit facility. The Wells Revolving Credit Agreement matures on April 1, 2023, subject to earlier termination upon the occurrence of certain events of default as set forth in the Wells Revolving Credit Agreement. Loans under the Wells Revolving Credit Agreement will bear interest at a fluctuating rate per annum equal to: (i) the Daily Simple SOFR (as defined herein) plus (ii) an applicable margin, which will equal 1.00%, 1.25%, 1.5% or 2.0% per annum depending on the Company’s senior funded debt to EBITDA ratio. The “Daily Simple SOFR” is calculated based upon the greater of (x) a floor of 0.00% and (b) the Secured Overnight Financing Rate, as established by the Federal Reserve Bank of New York (or a successor thereto) from time to time. Accrued interest is payable on the last day of each quarter, commencing June 30, 2022. Borrowings under the Wells Revolving Credit Agreement may be used solely for issuing letters of credit, financing capital expenditures, and working capital and general corporate purposes. Loans under the Wells Revolving Credit Agreement are secured by a first priority security interest in all of the accounts receivable of the Company and its subsidiary, ADTRAN International, Inc. Specifically, in connection with the Wells Revolving Credit Agreement, the Company entered into a security agreement, dated April 1, 2022, pursuant to which the Company pledged to the Wells Lender all of the rights to payment, accounts, deposit accounts, chattel paper (whether electronic or tangible), instruments, promissory notes, documents, licenses, general intangibles, payment intangibles, software, letter of credit rights and healthcare insurance receivables existing as of the date of execution or arising at any time thereafter. During the first half of 2022, the Company made draws totaling $10.0 million under the Wells Revolving Credit Agreement all of which had been repaid as of June 30, 2022. As of June 30, 2022, the Company was in compliance with all contractual requirements under the Wells Fargo Credit Agreement.

Earnings per share – diluted	$	0.04	$	0.10	$	0.02	$	0.12

For the three months ended June 30, 2022 and 2021, 33 thousand and one thousand shares, respectively, and for the six months ended June 30, 2022 and 2021, eight thousand and three thousand, respectively, of unvested PSUs, RSUs and restricted stock were excluded from the calculation of diluted earnings per share due to their anti-dilutive effect.

For the three months ended June 30, 2022 and 2021, 0.2 million and 0.4 million stock options, respectively, and for the six months ended June 30, 2022 and 2021, 0.1 million and 0.6 million stock options, respectively, were outstanding but were not included in the computation of diluted earnings per share. These stock options were excluded because their exercise prices were greater than the average market price of the common shares during the applicable period, making them anti-dilutive under the treasury stock method.

15. SEGMENT INFORMATION

The chief operating decision maker regularly reviews the Company’s financial performance based on two reportable segments: (1) Network Solutions and (2) Services & Support. Network Solutions includes hardware and software products and next-generation virtualized solutions used in service provider or business networks, as well as prior-generation products. Services & Support includes a portfolio of maintenance, network installation and solution integration services, which include hosted cloud services and subscription services.

The performance of these segments is evaluated based on gross profit; therefore, selling, general and administrative expenses, research and development expenses, interest and dividend income, interest expense, net investment gain (loss), other income (expense), net and income tax benefit (expense) are reported on a Company-wide basis only. There is no inter-segment revenue. Asset information by reportable segment is not produced and, therefore, is not reported.

16. LIABILITY FOR WARRANTY RETURNS

Our products generally include warranties of 90 days to five years for product defects. We accrue for warranty returns at the time of product shipment based on our historical return rate and estimate of the cost to repair or replace the defective products. We engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. The increasing complexity of our products may cause warranty incidences, when they arise, to be more costly. Estimates regarding future warranty obligations may change due to product failure rates, material usage and other rework costs incurred in correcting a product failure. In addition, from time to time, specific warranty accruals may be recorded if unforeseen problems arise. Should our actual experience relative to these factors be worse than our estimates, we will be required to record additional warranty expense. The liability for warranty obligations totaled $4.8 million and $5.4 million as of June 30, 2022 and December 31, 2021, respectively, and is included in accrued expenses and other liabilities in the Condensed Consolidated Balance Sheets. During the three months ended June 30, 2021, we had a net reversal of prior provisions related to warranty expirations the impact of which is reflected in the table below. The warranty expense and write-off activity for the three and six months ended June 30, 2022 and 2021 is summarized as follows:


	Three Months Ended						Six Months Ended

17. COMMITMENTS AND CONTINGENCIES

Shareholder Derivative Lawsuit

On March 31, 2020, a shareholder derivative suit, captioned Johnson (Derivatively on behalf of ADTRAN) v. Stanton, et al., Case No. 5:20-cv-00447, was filed in the U.S. District Court for the Northern District of Alabama against two of the Company’s current executive officers, one of its former executive officers, and certain current and former members of its Board of Directors, alleging, among other things, that the defendants made or caused the Company to make materially false and misleading statements regarding, and/or failed to disclose material adverse facts about, the Company’s business, operations and prospects, specifically relating to the Company’s internal control over financial reporting, excess and obsolete inventory reserves, financial results and demand from certain customers. The plaintiff in the shareholder derivative suit sent a demand letter dated June 29, 2021 to ADTRAN’s Board of Directors. The letter contains similar allegations to those made in the plaintiff’s filed complaint and in the now dismissed securities class action, and it demands, among other things, that the Board of Directors commence an investigation into the alleged wrongdoing. On December 10, 2021, after investigating the allegations in the plaintiff’s demand with the assistance of independent counsel, the independent members of the Board of Directors concluded that pursuing the claims asserted in the demand would not be in the Company's best interests and exercised their business judgment to refuse the demand. The plaintiff subsequently dismissed the case. On February 25, 2022, the Court entered an order on the parties’ joint stipulation dismissing the case without prejudice.

Other Legal Matters

In addition to the litigation described above, from time to time we are subject to or otherwise involved in various lawsuits, claims, investigations and legal proceedings that arise out of or are incidental to the conduct of our business (collectively, “Legal Matters”), including those relating to employment matters, patent rights, regulatory compliance matters, stockholder claims, and contractual and other commercial disputes. Such Legal Matters, even if not meritorious, could result in the expenditure of significant financial and managerial resources. Additionally, an unfavorable outcome in a legal matter, including in a patent dispute, could require the Company to pay damages, entitle claimants to other relief, such as royalties, or could prevent the Company from selling some of its products in certain jurisdictions. At this time, we are unable to predict the outcome of or estimate the possible loss or range of loss, if any, associated with such legal matters.

Performance Bonds

Certain contracts, customers and jurisdictions in which we do business require us to provide various guarantees of performance such as bid bonds, performance bonds and customs bonds. As of June 30, 2022 and December 31, 2021, we had commitments related to these bonds totaling $21.8 million and $22.9 million, respectively, which expire at various dates through April 2025. In general we would only be liable for the amount of these guarantees in the event of default under each contract, the probability of which we believe is remote.

In June 2020, the Company entered into a letter of credit with a bank to guarantee performance obligations under a contract with a certain customer. The obligations under this customer contract will be performed over multiple years. We reached the maximum value of our minimum collateral requirement of $15.0 million during the three months ended March 31, 2021 as the Company reached certain milestones through the first quarter of 2021 as outlined in the customer contract. In conjunction with the Company entering into the revolving credit facility with Wells Fargo during the three months ended June 30, 2022, our obligation to maintain the pledged collateral was released. This pledged collateral value fluctuated as the Company changed the mix of the pledged collateral between restricted cash and investments. Any shortfalls in the minimum collateral value was required to be restored by the Company from available cash and cash equivalents, short-term investments and/or long-term investments. For additional information on the Wells Fargo revolving credit facility see Note 12 of the Notes to Condensed Consolidated Financial Statements, included in Part I, Item 1 of this report.

Investment Commitment

We have committed to invest up to an aggregate of $5.0 million in a private equity fund, of which $4.9 million has been invested as of June 30, 2022.

18. RESTRUCTURING

During the second half of 2019, the Company initiated a restructuring plan to realign its expense structure with the reduction in revenue experienced in recent years and overall Company objectives. As part of this restructuring plan, the Company announced plans to reduce its overall operating expenses, both in the U.S. and internationally. Management continued to assess the efficiency of operations during 2020 and the first three months of 2021 and, in turn, consolidated locations and personnel, among other things, where possible.

In February 2019, the Company announced the restructuring of a certain portion of its workforce predominantly in Germany, which included the closure of the Company’s office location in Munich, Germany accompanied by relocation or severance benefits for the affected employees. Voluntary early retirement was offered to certain other employees and was announced in March 2019 and again in August 2020.

The cumulative amount of restructuring expenses incurred as of June 30, 2022 for the restructuring plans was $12.7 million.

A reconciliation of the beginning and ending restructuring liability, which is included in accrued wages and benefits in the Condensed Consolidated Balance Sheets is as follows:

19. SUBSEQUENT EVENTS

On August 3, 2022, we announced that our Board of Directors declared a quarterly cash dividend of $0.09 per common share to be paid to the Company’s stockholders of record as of the close of business on August 18, 2022. The payment date will be September 1, 2022 in the aggregate amount of approximately $7.0 million.

Closing of the Business Combination with ADVA

As previously disclosed, on July 8, 2022, Acorn MergeCo, Inc. (“Merger Sub”), a Delaware corporation and wholly-owned direct subsidiary of ADTRAN Holdings, Inc. (f/k/a Acorn HoldCo, Inc.) (the “Company”), merged with and into ADTRAN, Inc. (“ADTRAN”), with ADTRAN surviving the merger as a wholly-owned direct subsidiary of the Company (the “Merger”). The Merger was consummated pursuant to the Business Combination Agreement (the “Business Combination Agreement”), dated as of August 30, 2021, by and among the Company, ADTRAN, ADVA Optical Networking SE, a company organized and existing under the laws of Germany (“ADVA”), and Merger Sub.

Pursuant to the Business Combination Agreement, the Company made a public offer to exchange each issued and outstanding no-par value bearer share of ADVA for 0.8244 shares of common stock, par value $0.01 per share (the “Company Common Stock”), of the Company (the “Exchange Offer” and, together with the Merger, the “Business Combination”). The acceptance period for the Exchange Offer ended on February 14, 2022, and on July 6, 2022, the Company announced that all special offer conditions to the consummation of the Exchange Offer had been satisfied. The Exchange Offer was settled on July 15, 2022 (the “Exchange Offer Settlement Date”) in which the Company acquired 33,957,538 bearer shares of ADVA, or 65.43% of ADVA’s outstanding bearer shares as of the Exchange Offer Settlement Date, in exchange for the issuance of an aggregate of 27,994,595 shares of Company Common Stock. Based on the Company's closing share price as of July 15, 2022 of $20.20, the value of the Company Common Stock provided in exchange for ADVA common stock was approximately $565.5 million.

The issuance of shares of Company Common Stock in connection with the Business Combination was registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a registration statement on Form S-4 (the “Registration Statement”) (File No. 333-259251), which was declared effective by the U.S. Securities and Exchange Commission on December 2, 2021, and which included a proxy statement of ADTRAN for the special meeting of the stockholders of ADTRAN at which ADTRAN’s stockholders voted to adopt the Business Combination Agreement and that also constituted a prospectus for the Company (the “Proxy Statement”).

The Company Common Stock is listed on the Nasdaq Global Select Market (“Nasdaq”) and trades under the symbol “ADTN”. The Company Common Stock was also approved for listing on the regulated market segment (regulierter Markt) of the Frankfurt Stock Exchange (Frankfurter Wertpapierbörse) with simultaneous admission to the sub-segment thereof with additional post-admission obligations (Prime Standard) on July 13, 2022 and trades there under the symbol “QH9”.

For the three and six months ended June 30, 2022, the Company incurred $0.9 million and $1.8 million of transaction costs and were recognized as selling, general and administrative expense and research and development expense in our Condensed Consolidated Statements of Income, respectively. For the three and six months ended June 30, 2021, the Company incurred $2.4 million and $3.4 million of transaction costs and were recognized as selling, general and administrative expense and research and development expense in our Condensed Consolidated Statements of Income, respectively.

We expect that the business combination will be accounted for using the acquisition method of accounting under ASC 805, with ADTRAN Holdings, Inc. representing the accounting acquirer under this guidance. Due to the timing of the acquisition subsequent to our June 30, 2022 reporting period end, the initial accounting, including the allocation of purchase price and supplemental pro forma information, is incomplete as of the filing date and, therefore, related disclosures are not included herein.

Assumed ADVA Options

Pursuant to the Business Combination which closed on July 15, 2022, ADVA stock option holders were entitled to have their ADVA stock options assumed by ADTRAN Holdings (applying the exchange ratio in the Business Combination Agreement), thereafter representing options to acquire stock of ADTRAN Holdings. The maximum number of shares of ADTRAN Holdings stock potentially issuable upon such assumption was 2.1 million shares. The period in which such options could be assumed ended July 22, 2022. A total of 2.0 million shares of ADTRAN Holdings stock are subject to assumed ADVA options. The fair value of the stock options assumed by ADTRAN Holdings will be estimated using a Black-Scholes model. Our valuation of this component of consideration is not yet complete.

Wells Fargo Credit Agreement

On July 18, 2022, ADTRAN Holdings, Inc. and ADTRAN, Inc., as the borrower, entered into a credit agreement with a syndicate of banks, including Wells Fargo Bank, National Association, as administrative agent (“Administrative Agent”), and the other lenders named therein (the “Credit Agreement”). The Credit Agreement allows for borrowings of up to $100 million in aggregate principal amount, subject to being increased to up to $400 million in aggregate principal amount upon the Company or Borrower’s execution of a domination and profit and loss transfer agreement with ADVA or a parent of ADVA, among other conditions (the “Senior Credit Facilities Increase”).

The Credit Agreement replaced the Cadence Revolving Credit Agreement and the Wells Fargo Revolving Credit Agreement. In connection with the entry into the Credit Agreement, all outstanding borrowings under such credit agreements have been repaid and the agreements terminated.

As of August 5, 2022, ADTRAN, Inc.’s borrowings under the revolving line of credit were $50.0 million. In addition, a $17.5 million letter of credit with ADTRAN, Inc. remains outstanding. Any future credit extensions under the Credit Agreement are subject to customary conditions precedent. The proceeds of any loans are expected to be used for general corporate purposes and to pay a portion of the Exchange Offer consideration.

All U.S. borrowings under the Credit Agreement (other than swingline loans, which will bear interest at the Base Rate (as defined below)) will bear interest, at the Company’s option, at a rate per annum equal to (A)(i) the highest of (a) the federal funds rate (i.e., for any day, the rate per annum equal to the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System, as published by the Federal Reserve Bank of New York on the business day next succeeding such day) plus ½ of 1%, (b) the prime commercial lending rate of the Administrative Agent, as established from time to time at its principal U.S. office (which such rate is an index or base rate and will not necessarily be its lowest or best rate charged to its customers or other banks), and (c) the daily Adjusted Term SOFR (as defined in the Credit Agreement) for a one-month tenor plus 1%, plus (ii) the applicable rate, ranging from 0.5% to 1.25% (the “Base Rate”), or (B) the sum of the Adjusted Term SOFR (as defined in the Credit Agreement) plus the applicable rate, ranging from 1.4% to 2.15%, provided that such sum is subject to a 0.0% floor (such loans utilizing this interest rate, “SOFR Loans”). All E.U. borrowings under the Credit Agreement (other than swingline loans) will bear interest at a rate per annum equal to the sum of the Euro Interbank Offered Rate as administered by the European Money Markets Institute (or a comparable or successor administrator approved by the Administrative Agent) plus the applicable rate, ranging from 1.5% to 2.25%, provided that such sum is subject to a 0.0% floor (such loans utilizing this interest rate, “EURIBOR Loans”). The applicable rate is based on the consolidated net leverage ratio of the Company and its subsidiaries as determined pursuant to the terms of the Credit Agreement. Default interest is 2.00% per annum in excess of the rate otherwise applicable in the case of any overdue principal or any other overdue amount.

In addition to paying interest on outstanding principal under the Credit Agreement, the Company is required to pay a commitment fee to the lenders under the Credit Agreement in respect of unutilized revolving loan commitments and an additional commitment ticking fee at a rate of 0.25% on the commitment amounts of each lender until the earliest of (i) the date of the Senior Credit Facilities Increase, (ii) the Company’s voluntary termination of the credit facility commitment, and (iii) December 31, 2023. The Company is also required to pay a participation fee to the Administrative Agent for the account of each lender with respect to the Company’s participations in letters of credit at the then applicable rate for SOFR Loans.

The Credit Agreement will mature on July 14, 2027, with the Company’s option to request extensions subject to customary conditions. The Credit Agreement permits the Company to prepay any or all of the outstanding loans or to reduce the commitments under the Credit Agreement without incurring premiums or penalties (except breakage costs with respect to SOFR Loans and EURIBOR Loans).

The Credit Agreement contains customary affirmative and negative covenants, including incurrence covenants and certain other limitations on the ability of the Company and the Company’s subsidiaries to incur additional debt, guarantee other obligations, grant liens on assets, make investments, dispose of assets, pay dividends or other payments on capital stock, make restricted payments, engage in mergers or consolidations, engage in transactions with affiliates, modify its organizational documents, and enter into certain restrictive agreements. It also contains customary events of default (subject to customary cure periods and materiality thresholds).

Furthermore, the Credit Agreement requires that the Consolidated Total Net Leverage Ratio (as defined in the Credit Agreement) of the Company and its subsidiaries tested on the last day of each fiscal quarter not to exceed 3.25 to 1.00 through September 30, 2024 and 2.75 to 1.00 from December 31, 2024 and thereafter, subject to certain exceptions. The Credit Agreement also requires that the Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) of the Company and its subsidiaries tested on the last day of each fiscal quarter not fall below 3.00 to 1.00.

Finally, pursuant to a Collateral Agreement, dated as of July 18, 2022, among the Company, ADTRAN, Inc. and the Administrative Agent, ADTRAN, Inc.’s obligations under the Credit Agreement are secured by substantially all of the assets of ADTRAN, Inc. and the Company. In addition, the Company has guaranteed ADTRAN, Inc.’s obligations under the Credit Agreement pursuant to a Guaranty Agreement, dated as of July 18, 2022, by ADTRAN, Inc. and the Company in favor of the Administrative Agent.

BUSINESS COMBINATION WITH ADVA

On July 15, 2022, the Company settled a public offer to exchange each issued and outstanding no-par value bearer share of ADVA, in which each ADVA share tendered and accepted for exchange was exchanged for 0.8244 shares of common stock, par value $0.01 per share (the “Company Common Stock”), of ADTRAN Holdings, Inc. (the “Exchange Offer” and, together with the Merger, the “Business Combination”). At the settlement of the Exchange Offer, the Company acquired 33,957,538 bearer shares of ADVA, or 65.43% of

ADVA’s outstanding bearer shares as of the Exchange Offer Settlement Date, in exchange for the issuance of an aggregate of 27,994,595 shares of Company Common Stock. As a result of the Business Combination, the Company has significantly increased its presence around the world with offices in more than 38 countries with approximately 3,486 employees worldwide. We believe that the combination of talent, industry-leading solution portfolios, and vision for innovation from both ADTRAN, Inc. and ADVA positions the Company as a global leader for service provider, government, and enterprise customers and will provide a firm foundation for our success moving forward.

The Company and ADVA have agreed to enter into negotiations regarding the conclusion of a domination agreement or a domination and profit and loss transfer agreement within the meaning of Sec. 291 para. 1 of the German Stock Corporation Act (Aktiengesetz) (a “DPLTA”), between ADVA, as the dominated entity, and the Company (or a to-be-established subsidiary of the Company), as dominating entity. The effectiveness of the DPLTA is intended to allow both companies to fully integrate and work towards achievement of operational synergy targets.

During the three months ended June 30, 2022, we recognized $0.9 million of transaction costs. We expect to incur an estimated $14.9 million of additional transaction costs related to the Business Combination and we will continue to incur integration costs and costs associated with the negotiation and implementation, if any, of a DPLTA, during the remainder of the year and such costs are expected to be material. Since the Exchange Offer did not settle until July 15, 2022, the operations of ADVA were not included in our consolidated operating results for the three months ended June 30, 2022.

FINANCIAL PERFORMANCE AND TRENDS

We ended the second quarter of 2022 with a year-over-year revenue increase of 20.1% as compared to the three months ended June 30, 2021, driven by increased sales to Tier-1, Tier-2 and Tier-3 service providers. During the second quarter of 2022, we had three 10% revenue customers; two U.S. distributors and one U.S. service provider customer. Our year-over-year domestic revenue increased by 11.7%, driven by increased volume of network termination and Fiber CPE in our Network Solutions segment. Internationally, our revenue increased by 36.5% compared to the prior year period, primarily driven by increased shipments to a Tier-1 network operator and multiple alternative network operators in Europe. We experienced strong demand for our solutions in the first half of 2022 and achieved significant year-over-year bookings growth. Bookings are defined as orders received for a product or service during a fiscal period that will be delivered or performed sometime in the future and is a forward looking metric that we utilize to help us understand future revenue growth for the Company. Bookings are generally subject to modification and or cancellation per the terms of the order. A substantial portion of our shipments in any fiscal period relates to orders received and shipped within that fiscal period for customers under agreements containing nonbinding purchase commitments. Our increase in demand comes from service providers planning to deploy our fiber access platforms, in-home service delivery platforms and SaaS applications. We expect this growth to accelerate. During 2021 and continuing in 2022, we secured several Tier-1 next-generation fiber customers, and previously announced Tier-1 fiber customers significantly increased their bookings for our fiber access platforms. Although we expect our revenue growth and profitability in the near-term to continue to be negatively impacted by supply chain issues, our outlook continues to strengthen given the increased demand for our products and our expectation of an improving supply chain over the longer term.

In March 2020, the World Health Organization declared the novel coronavirus (COVID-19) outbreak a global pandemic. The SARS-CoV-2 coronavirus (or variants of the SARS-CoV-2 coronavirus) continues to spread throughout the U.S. and the world and has resulted in authorities implementing varying measures to contain the virus. Although vaccines have been approved and continue to be distributed, it cannot be predicted how long it will take before market conditions return to normal and there can be no assurance that the economic recovery will occur or offset the uncertainty and instability triggered by the pandemic. New and potentially more contagious variants of the COVID-19 virus may develop in various countries, including in regions in which we have significant operations. The COVID-19 variants could further amplify the impact of the pandemic. While we are unable to accurately predict the full impact that the COVID-19 global pandemic will have on our results of operations, financial condition, liquidity and cash flows due to numerous uncertainties, including the duration and severity of the pandemic and containment measures, our compliance with these measures has impacted our day-to-day operations and could disrupt our business and operations, as well as that of our key customers, suppliers and other counterparties, for an indefinite period of time. We have experienced a significant impact to our supply chain given COVID-19 and the related global semiconductor chip shortage, including delays in supply chain deliveries, extended lead times and shortages of some key components, some raw material cost increases and slowdowns at certain production facilities. We have also had to increase our volume of inventory to ensure supply continuity during the pandemic. In addition, we have experienced significant increases in freight-related costs due to global shipping disruptions. Starting in the third quarter of 2021 and continuing into 2022, the Company has incurred supply chain constraint expenses, including price inflation for certain electronic components, semiconductor chips and transportation related costs, which have lowered our gross margins and decreased our profitability. While throughout the pandemic we have seen increased demand in networking requirements and utilization due to social distancing guidelines issued by governments, as well as COVID-19 related reductions in travel and infrastructure expenses, it is possible that we could experience some slowdown in demand, further supply chain issues and an increased impact from the ongoing semiconductor shortage and shortages of certain other key components as the pandemic continues. If the impacts of this shortage are more severe than we expect, it could result in longer lead times, inventory supply challenges and further increased costs, all of which could result in the deterioration of our results, potentially for a longer period than currently anticipated. To support the health and well-being of our employees, customers, partners and communities, many of our

employees are working remotely or on a hybrid schedule as of the date of filing this report. Additionally, there is risk that a number of our employees may become infected with COVID-19, including our key personnel. In addition, actions that have been taken and that may be taken by the Company, its customers, suppliers and counterparties in response to the pandemic, including the implementation of alternative work arrangements for certain employees, as well as the impacts to our supply chain, including delays in supply chain deliveries and the related global semiconductor chip shortage, have delayed and may continue to delay the timing of some orders and expected deliveries. Lastly, even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic recession that has occurred or may occur in the future as a result of the COVID-19 pandemic.

Among our customers, we made progress with our fiber, fiber-extension, in-home service delivery platforms and cloud services while also continuing to engage in value-added service opportunities that contributed to sales in 2021 and we expect will contribute to sales during 2022 and beyond. In addition, we believe that we are at the beginning of a significant investment cycle for fiber deployment and in-home Wi-Fi connectivity driven by technology advancements and regulatory influences. Payments to service providers under government funding programs such as the FCC RDOF started in 2021, and they are expected to continue in 2022. The transition to next-generation network architectures is beginning, and we are seeing demand for our next-generation fiber access and connected home solutions.

In addition to classifying our operations into two reportable segments, we report revenue across three categories of products and services – (1) Access & Aggregation, (2) Subscriber Solutions & Experience and (3) Traditional & Other Products.

Our Access & Aggregation platforms are used by CSPs to connect their network infrastructure to subscribers. This revenue category includes hardware- and software-based products and services that aggregate and/or originate access technologies. ADTRAN solutions within this category include a wide array of modular or fixed platforms designed to deliver the best technology and economy based on subscriber density and environmental conditions.

Our Subscriber Solutions & Experience portfolio is used by service providers to terminate their infrastructure at the customer’s premises while providing an immersive and interactive experience for the subscriber. These solutions include copper and fiber WAN termination, LAN switching, Wi-Fi access, and cloud software services, for both residential and business markets.

Our Traditional & Other Products category generally includes a mix of prior-generation technologies’ products and services, as well as other products and services that do not fit within the other revenue categories.

Our operating results have fluctuated, and may continue to fluctuate, on a quarterly basis due to several factors, including customer order activity, supply chain constraints, component availability, backlog and the Company's efforts to integrate with ADVA. A substantial portion of our shipments in any fiscal period relates to orders received and shipped within that fiscal period for customers under agreements containing non-binding purchase commitments. Further, a significant percentage of orders require delivery within a few days requiring us to maintain higher inventory levels. These factors normally result in a varying order backlog and limited order flow visibility; however, with the current global supply chain and transportation constraints, and limited availability of semiconductor chips and other components of our products, we have experienced and may continue to experience extended lead times, increased logistics intervals and costs, and lower volume of products deliveries, which has had and may continue to have a material adverse effect on our operating results and could have a material adverse effect on customer relations and our financial condition. Normal operating expenses are relatively fixed in the short term; therefore, a shortfall in quarterly revenues could significantly impact our financial results in a given quarter.

We are exposed to changes in foreign currencies relative to the U.S. dollar, which are references to the differences between the foreign-exchanges rates we use to convert the financial results of our international operations from local currencies into U.S. dollars for financial reporting purposes. This impact of foreign-exchange rate changes is calculated based on the difference between the current period’s currency exchange rates and that of the comparable prior period. Our primary exposures to foreign currency exchange rate movements are with our European subsidiaries, whose functional currency is the Euro, our Australian subsidiary, whose functional currency is the Australian dollar, and our U.K. subsidiary, who transacts in the British pound sterling with a U.S. dollar functional currency. As a result of our global operations, our revenue, gross margins, operating expense and operating income in some international markets have been and may continue to be affected by foreign currency fluctuations.

We continue to support our customer demand for our products by working with our suppliers, contract manufacturers, distributors, and customers to address and to limit the disruption to our operations and order fulfillment.

Our operating results may also fluctuate as a result of a number of other factors, including a decline in general economic and market conditions, specifically the decline that initially resulted from the COVID-19 pandemic and that may recur, foreign currency exchange rate movements, inflation, regional conflicts, increased competition, customer order patterns, changes in product and services mix, timing differences between price decreases and product cost reductions, product warranty returns, expediting costs, tariffs and announcements of new products by us or our competitors. Specifically, we expect inflationary pressures on input costs, such as raw materials and labor, and distribution costs to increase. Our attempts to offset these cost pressures, such as through increases in the selling prices of some of our products and services, may not be successful and could negatively affect our operating results. Additionally, maintaining sufficient inventory levels to assure prompt delivery of our products increases the amount of inventory that may become

obsolete and increases the risk that the obsolescence of this inventory may have an adverse effect on our business and operating results. Also, not maintaining sufficient inventory levels to assure prompt delivery of our products may cause us to incur expediting costs to meet customer delivery requirements, which may negatively impact our operating results. In recent years, the Company initiated restructuring plans to realign its expense structure with the reduction in revenue experienced and with overall Company objectives. Management assessed the efficiency of our operations and consolidated locations and personnel, among other things, and implemented certain cost savings initiatives, where possible. See Note 18 of the Notes to Condensed Consolidated Financial Statements included in Part 1, Item 1 of this report for additional information on this restructuring.

Our historical financial performance is not necessarily a meaningful indicator of future results, and in general, management expects that our financial results may vary from period to period. Factors that could materially affect our business, financial condition or operating results are included in Part I, Item 1A of the 2021 Form 10-K and Part II, Item 1A of this Form 10-Q.

REVENUE

Our revenue increased 20.1% from $143.2 million for the three months ended June 30, 2021 to $172.0 million for the three months ended June 30, 2022 and increased 20.6% from $270.8 million for the six months ended June 30, 2021 to $326.6 million for the six months ended June 30, 2022. The increase in revenue for the three months ended June 30, 2022 was primarily attributable to a $30.3 million increase in Subscriber Solutions & Experience products partially offset by a $1.2 million decrease in Access & Aggregation revenue and a $0.3 million decrease in our Traditional & Other Products, respectively. The increase in revenue for the six months ended June 30, 2022 was attributable to a $30.4 million increase in Subscriber Solutions & Experience products, a $25.2 million increase in Access & Aggregation revenue and a $0.2 million increase in the revenue of our Traditional & Other Products, respectively. Although our revenue increased, supply of semiconductor chips and other components of our products has become constrained resulting in extended lead times and increased costs. Transportation constraints, including shortages for both air and surface freight, as well as labor shortages in the transportation industry, have also affected the timing and the cost of obtaining raw materials and production supplies. Although our revenue growth and profitability in the near-term may be impacted by these global supply chain issues, our longer term outlook continues to strengthen given our progress with new customer opportunities and the increased customer demand.

Network Solutions segment revenue increased 24.3% from $125.4 million for the three months ended June 30, 2021 to $156.0 million for the three months ended June 30, 2022 and increased 23.0% from $239.3 million for the six months ended June 30, 2021 to $294.4 million for the six months ended June 30, 2022. The increase in revenue for the three months ended June 30, 2022 was due primarily to revenue of Subscriber Solutions & Experience and Access & Aggregation products. The increase in revenue for the six months ended June 30, 2022 was due to all revenue categories. While we expect that revenue from Traditional & Other Products will continue to decline over time, this revenue may fluctuate and continue for years because of the time required for our customers to transition to newer technologies.

Services & Support segment revenue decreased 9.8% from $17.8 million for the three months ended June 30, 2021 to $16.0 million for the three months ended June 30, 2022 and increased 2.2% from $31.5 million for the six months ended June 30, 2021 to $32.2 million for the six months ended June 30, 2022. The decrease in revenue for the three months ended June 30, 2022 was primarily attributable to decreased revenue of Access & Aggregation products. The increase in revenue for the six months ended June 30, 2022 was primarily attributable to increased revenue of Subscriber Solutions & Experience products.

International revenue, which is defined as revenue generated from the Network Solutions and Services & Support segments provided to a customer outside of the U.S., increased by 36.5% from $48.6 million for the three months ended June 30, 2021 to $66.3 million for the three months ended June 30, 2022 and increased by 35.9% from $89.6 million for the six months ended June 30, 2021 to $121.8 million for the six months ended June 30, 2022. International revenue, as a percentage of total revenue, increased from 33.9% for the three months ended June 30, 2021 to 38.5% for the three months ended June 30, 2022 and increased from 33.1% for the six months ended June 30, 2021 to 37.3% for the six months ended June 30, 2022. The increase in percentage of international revenue for the three and six months ended June 30, 2022, was primarily driven by increased shipments to a Tier-1 network operator and multiple alternative network operators in Europe. For the three and six months ended June 30, 2022 as compared to the three and six months ended June 30, 2021, changes in foreign currencies relative to the U.S dollar decreased our net sales by approximately $6.5 million and $8.8 million, respectively.

Our international revenue is largely focused on broadband infrastructure and is consequently affected by the decisions of our customers as to timing for installation of new technologies, expansion of their networks and/or network upgrades. Our international customers must make these decisions in the regulatory and political environment in which they operate – both nationally and in some instances, regionally – whether of a multi-country region or a more local region within a country. Consequently, while we expect the global trend towards deployment of more robust broadband speeds and access to continue creating additional market opportunities for us, the factors described above may result in pressure on revenue and operating income.

COST OF REVENUE

As a percentage of revenue, cost of revenue increased from 56.2% for the three months ended June 30, 2021 to 63.7% for the three months ended June 30, 2022 and increased from 57.1% for the six months ended June 30, 2021 to 64.2% for the six months ended June 30, 2022. For the three and six months ended June 30, 2022, the increase was primarily attributable to supply chain constraint related expenses and to a lesser extent changes in customer and product mix and a regional revenue shift. For the three and six months ended June 30, 2022, as compared to the three and six months ended June 30, 2021, changes in foreign currencies relative to the U.S. dollar decreased our cost of revenue by approximately $2.5 million and $3.4 million, respectively.

Network Solutions cost of revenue, as a percentage of that segment’s revenue, increased from 55.8% for the three months ended June 30, 2021 to 64.1% for the three months ended June 30, 2022 and increased from 56.4% for the six months ended June 30, 2021 to 64.7% for the six months ended June 30, 2022. The increase in cost of revenue as a percentage of revenue for the three and six months ended June 30, 2022 was primarily attributable to supply chain constraint related expenses and to a lesser extent changes in customer and product mix and a regional revenue shift.

Services & Support cost of revenue, as a percentage of that segment’s revenue, increased from 59.3% for the three months ended June 30, 2021 to 59.9% for the three months ended June 30, 2022 and decreased from 61.8% for the six months ended June 30, 2021 to 59.5% for the six months ended June 30, 2022. The fluctuation in cost of revenue as a percentage of revenue for the three and six months ended June 30, 2022 was primarily attributable to customer mix, changes in services and support mix.

Services & Support revenue is comprised of network planning and implementation, maintenance, support and cloud-based management services, with network planning and implementation being the largest and fastest growing component in the long-term. Compared to our other services, such as maintenance, support and cloud-based management services, our network planning and implementation services typically utilize a higher percentage of internal and subcontracted engineers, professionals and contractors to perform the work for customers. The additional costs incurred to perform these infrastructure and labor-intensive services inherently result in lower average gross margins as compared to maintenance and support services. Within the Services & Support segment, we do expect variability in gross margins from quarter-to-quarter based on the mix of the services recognized.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

As a percentage of revenue, selling, general and administrative expenses decreased from 21.5% for the three months ended June 30, 2021 to 16.2% for the three months ended June 30, 2022 and decreased from 21.5% for the six months ended June 30, 2021 to 17.1% for the six months ended June 30, 2022. Selling, general and administrative expenses as a percentage of revenue will generally fluctuate whenever there is a significant fluctuation in revenue for the periods being compared.

Selling, general and administrative expenses decreased 9.7% from $30.9 million for the three months ended June 30, 2021 to $27.9 million for the three months ended June 30, 2022 and decreased 4.3% from $58.3 million for the six months ended June 30, 2021 to $55.8 million for the six months ended June 30, 2022. The decrease in selling, general and administrative expenses for the three months ended June 30, 2022 was primarily attributable to lower market driven expenses in our deferred compensation portfolio partially offset by increased salary and commission expenses and travel expense. The decrease in selling, general and administrative expenses for the six months ended June 30, 2022 was primarily attributable to lower in market driven expenses in our deferred compensation portfolio partially offset by increased salary and commission expenses, travel expense, acquisition expense and insurance expense. For the three and six months ended June 30, 2022 as compared to the three and six months ended June 30, 2021, changes in foreign currencies relative to the U.S dollar decreased our selling, general and administrative expenses by approximately $0.6 million and $1.0 million, respectively.

RESEARCH AND DEVELOPMENT EXPENSES

As a percentage of revenue, research and development expenses decreased from 19.5% for the three months ended June 30, 2021 to 15.4% for the three months ended June 30, 2022 and decreased from 20.5% for the six months ended June 30, 2021 to 16.2% for the six months ended June 30, 2022. Research and development expenses as a percentage of revenue will fluctuate whenever there are incremental product development activities or significant fluctuations in revenue for the periods being compared.

Research and development expenses decreased 4.9% from $27.9 million for the three months ended June 30, 2021 to $26.5 million for the three months ended June 30, 2022 and decreased 4.3% from $55.4 million for the six months ended June 30, 2021 to $53.0 million for the six months ended June 30, 2022. The decrease in research and development expenses for the three and six months ended June 30, 2022 was primarily attributable to contract services, lower labor, and depreciation expense. For the three and six months ended June 30, 2022 as compared to the three and six months ended June 30, 2021, changes in foreign currencies relative to the U.S. dollar decreased our research and development expenses by approximately $0.7 million and $1.1 million, respectively.

We expect to continue to incur research and development expenses in connection with our new and existing products. We continually evaluate new product opportunities and engage in significant research and product development efforts, which provides for new product development, enhancement of existing products and product cost reductions. We may incur significant research and development expenses prior to the receipt of revenue from a major new product group.

INTEREST AND DIVIDEND INCOME

Interest and dividend income decreased 14.2% from $0.3 million for the three months ended June 30, 2021 to $0.2 million for the three months ended June 30, 2022 and decreased 22.5% from $0.5 million for the six months ended June 30, 2021 to $0.4 million for the six months ended June 30, 2022. Although the rate of return investments was up during the three and six month ended June 30, 2022, interest and dividend income was down due to a decrease in the investment balance. Our total long-term investments decreased from $82.8 million as of June 30, 2021 to $52.3 million as of June 30, 2022.

INTEREST EXPENSE

Interest expense was less than $0.1 million for the three months ended June 30, 2022 and $0.1 million for the six months ended June 30, 2022. Interest expense and was less than $0.1 million for each of the three and six months ended June 30, 2021. Interest expense during the three and six months ended June 30, 2022 was primarily related to our Revolving Credit Agreement. See Note 12 of the Notes to Condensed Consolidated Financial Statements, included in Part I, Item 1 of this report.

NET INVESTMENT (LOSS) GAIN

We recognized a net investment gain of $2.0 million and a net investment loss of $4.6 million for the three months ended June 30, 2021 and 2022, respectively and recognized a net investment gain of $3.0 million and a net investment loss of $8.1 million for the six months ended June 30, 2021 and 2022, respectively. The fluctuations in our net investments were primarily attributable to changes in the fair value of our securities recognized during the period. We expect that any future market volatility could result in continued fluctuations in our investment portfolio. See Note 6 of the Notes to Condensed Consolidated Financial Statements, included in Part I, Item 1 of this report, and “Investing Activities” in “Liquidity and Capital Resources” below for additional information.

OTHER INCOME, NET

Other income, net, which primarily consisted of gains and losses on foreign currency transactions and income from excess material sales, increased from income of $26 thousand for the three months ended June 30, 2021 to income of $0.7 million for the three months ended June 30, 2022 and decreased from income of $2.0 million for the six months ended June 30, 2021 to income of $0.5 million for the six months ended June 30, 2022.

INCOME TAX EXPENSE (BENEFIT)

NET INCOME

As a result of the above factors, net income decreased from net income of $5.1 million for the three months ended June 30, 2021 to a net income of $2.1 million for the three months ended June 30, 2022 and decreased from net income of $6.0 million for the six months ended June 30, 2021 to a net income of $1.0 million for the six months ended June 30, 2022.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

We have historically financed, our ongoing business with existing cash, investments and cash flow from operations. In the current supply environment we also expect to utilize our credit arrangements to manage our working capital needs. We have used, and expect to continue to use, existing cash, investments, credit arrangements and cash generated from operations for working capital, business acquisitions, purchases of treasury stock, shareholder dividends and other general corporate purposes, including product development activities to enhance our existing products and develop new products, expand our sales and marketing activities and fund capital expenditures. As of June 30, 2022, ADTRAN has incurred $8.7 million of transaction costs related to the Business Combination and expects to incur an estimated $14.9 million of additional transaction costs related to the Business Combination. We believe that our cash and cash equivalents, investments, cash generated from operations and access to funds under the new Wells Fargo credit facility (described below) will be adequate to meet our operating and capital needs for at least the next 12 months.

As of June 30, 2022, cash on hand was $43.3 million and short-term investments were $1.8 million, which resulted in available short-term liquidity of $45.1 million, of which $27.0 million was held by our foreign subsidiaries. As of December 31, 2021, cash on hand was $56.6 million and short-term investments were $0.4 million, which resulted in available short-term liquidity of $57.0 million, of which $47.7 million was held by our foreign subsidiaries. Generally, we intend to permanently reinvest funds held outside the U.S., except to the extent that any of these funds can be repatriated without withholding tax.

Operating Activities

Net cash used in operating activities of $5.9 million during the six months ended June 30, 2022 decreased by $24.1 million compared to net cash provided of $18.2 million during the six months ended June 30, 2021. This decrease was primarily due to net cash outflows from working capital, specifically, an inventory build related to component availability and an increase in accounts receivables partially offset by an increase in the average number of days payable to our trade suppliers. Additional details related to our working capital and its drivers are discussed below.

Net accounts receivable increased 8.4% from $158.7 million as of December 31, 2021 to $172.1 million as of June 30, 2022. There was no allowance for credit losses as of June 30, 2022 and December 31, 2021. The increase in net accounts receivable was due primarily to an increase in sales volume. Quarterly accounts receivable DSO decreased from 95 days as of December 31, 2021 to 91 days as of June 30, 2022. The decrease in DSO was due to customer and geographical mix and timing of sales within the quarter.

Other receivables decreased 25.1% from $11.2 million as of December 31, 2021 to $8.4 million as of June 30, 2022. The decrease in other receivables was primarily attributable to the decrease in our receivables for sales of raw materials and duty drawbacks partially offset by an increase in contract assets.

Quarterly inventory turnover was 3.0 turns as of December 31, 2021 and 2.4 turns as of June 30, 2022, respectively. Inventory increased 40.8% from $139.9 million as of December 31, 2021 to $196.9 million as of June 30, 2022. The increase in inventory was due to strategic inventory buffer purchases given extended component lead times and availability constraints as well as new product ramp ups to ensure supply continuity during the COVID-19 pandemic. We expect inventory levels to fluctuate as we attempt to maintain sufficient inventory in response to COVID-19 uncertainties related to supply chain and supply, seasonal cycles of our business and ensuring competitive lead times while managing the risk of inventory.

Accounts payable increased 40.9% from $102.5 million as of December 31, 2021 to $144.4 million as of June 30, 2022. Accounts payable will fluctuate due to variations in the timing of the receipt of inventory, supplies and services and our subsequent payments for these purchases. The significant increase in the first half of 2022 was due to additional purchases of raw material inventory.

Investing Activities

Capital expenditures totaled approximately $3.3 million and $2.2 million for the six months ended June 30, 2022 and 2021, respectively. These expenditures were primarily used to purchase manufacturing and test equipment, software, computer hardware and building improvements.

Our combined short-term and long-term investments decreased $16.9 million from $71.0 million as of December 31, 2021 to $54.1 million as of June 30, 2022. This decrease reflects the impact of net unrealized and realized gains and losses on our investments as well as the sale of a portion of our equity investments.

We typically invest all available cash not required for immediate use in operations, primarily in securities that we believe bear minimal risk of loss. See Note 6 of the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this report for additional information.

As of June 30, 2022, our corporate bonds, municipal bonds, asset-backed bonds, mortgage/agency bonds, U.S. government bonds, other government bonds and variable-rate demand notes were classified as available-for-sale and had a combined duration of 1.75 years with an average Standard & Poor’s credit rating of AA-. Because our investment portfolio has a high-quality rating and contractual maturities of short duration, we are able to obtain prices for these bonds derived from observable market inputs, or for similar securities traded in an active market, on a daily basis.

Our long-term investments decreased 25.9% from $70.6 million as of December 31, 2021 to $52.3 million as of June 30, 2022. Our investments include various marketable equity securities classified as long-term investments with a fair market value of $0.9 million and $12.6 million as of June 30, 2022 and December 31, 2021, respectively. Long-term investments as of June 30, 2022 and December 31, 2021 also included $22.6 million and $26.9 million, respectively, related to our deferred compensation plans.

Financing Activities

Dividends

During the six month periods ended June 30, 2022 and 2021, we paid dividends totaling $8.9 million and $8.7 million, respectively. The continued payment of dividends is at the discretion of the Company’s Board of Directors and is subject to general business conditions and ongoing financial results of the Company.

Stock Option Exercises

To accommodate employee stock option exercises, the Company issued four thousand and 0.1 million shares of treasury stock which resulted in proceeds of $0.1 million and $2.3 million during the three months ended June 30, 2022 and 2021, respectively and issued 37 thousand and 0.2 million shares of treasury stock which resulted in proceeds of $0.6 million and $3.6 million during the six months ended June 30, 2022 and 2021, respectively.

Off-Balance Sheet Arrangements

We do not have off-balance sheet financing arrangements and have not engaged in any related party transactions or arrangements with unconsolidated entities or other persons that are reasonably likely to materially affect liquidity or the availability of or requirements for capital resources.

Cash Requirements

New Wells Fargo Credit Agreement

The Credit Agreement replaced ADTRAN, Inc.’s prior credit agreements with the Administrative Agent and Cadence Bank, N.A. entered into on April 1, 2022 and November 4, 2020, respectively. In connection with the entry into the Credit Agreement, all outstanding borrowings under such prior credit agreements have been repaid and the agreements terminated. As of August 5, 2022, ADTRAN, Inc.’s borrowings under the revolving line of credit were $50.0 million. In addition, a $17.5 million letter of credit with ADTRAN, Inc. remains outstanding. Any future credit extensions under the Credit Agreement are subject to customary conditions precedent. The proceeds of any loans are expected to be used for general corporate purposes and to pay a portion of the Exchange Offer consideration.

The Credit Agreement will mature on July 18, 2027, with the Company’s option to request extensions subject to customary conditions. The Credit Agreement permits the Company to prepay any or all of the outstanding loans or to reduce the commitments under the Credit Agreement without incurring premiums or penalties (except breakage costs with respect to SOFR Loans and EURIBOR Loans).

in mergers or consolidations, engage in transactions with affiliates, modify its organizational documents, and enter into certain restrictive agreements. It also contains customary events of default (subject to customary cure periods and materiality thresholds).

Furthermore, the Credit Agreement requires that the Consolidated Total Net Leverage Ratio (as defined in the Credit Agreement) of the Company and its subsidiaries tested on the last day of each fiscal quarter not exceed 3.25 to 1.0 through September 30, 2024 and 2.75 to 1.00 from December 31, 2024 and thereafter, subject to certain exceptions. The Credit Agreement also requires that the Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) of the Company and its subsidiaries tested on the last day of each fiscal quarter not fall below 3.00 to 1.00.

Certain contracts, customers and jurisdictions in which we do business require us to provide various guarantees of performance such as bid bonds, performance bonds and customs bonds. As of June 30, 2022 and December 31, 2021, we had commitments related to these bonds totaling $21.8 million and $22.9 million, respectively, which expire at various dates through April 2025. Although the triggering events vary from contract to contract, in general we would only be liable for the amount of these guarantees in the event of default under each contract, the probability of which we believe is remote.

Under the Business Combination Agreement, the Company will bear the transaction costs of the Business Combination attributable to ADTRAN Holding, Inc. (formerly known as Acorn HoldCo, Inc.) and the Company. As of June 30, 2022, ADTRAN has incurred $8.7 million of transaction costs related to the Business Combination and expects to incur an estimated $14.9 million of additional transaction costs related to the Business Combination.

In June 2020, we entered into a letter of credit with a bank to guarantee performance obligations under a contract with a customer. In conjunction with the Company entering into the revolving credit facility with Wells Fargo during the three months ended June 30, 2022, our obligation to maintain $15.0 million in pledged collateral was released. For additional information on the Wells Fargo revolving credit facility see Note 12 of the Notes to Condensed Consolidated Financial Statements, included in Part I, Item 1 of this report.

We have committed to invest up to an aggregate of $5.0 million in a private equity fund, of which $4.9 million has been invested as of June 30, 2022.

During the six months ended June 30, 2022, there have been no other material changes in cash requirements from those discussed in the 2021 Form 10-K. However, the Company anticipates that our commitments and contingencies will increase significantly due to the day-to-day business obligations of ADVA as a result of the Business Combination that closed on July 15, 2022.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to financial market risks, including changes in foreign currency rates, prices of marketable equity and fixed-income securities. In addition, the ongoing global pandemic raises the possibility of an extended economic downturn and has caused volatility in financial markets. The primary objective of the large majority of our investment activities is to preserve principal while at the same time achieving appropriate yields without significantly increasing risk. To achieve this objective, a majority of our marketable securities are investment grade, fixed-rate bonds and municipal money market instruments denominated in U.S. dollars. Our investment policy provides limitations for issuer concentration, by restricting, at the time of purchase, the concentration in any one issuer to 5% of the market value of our total investment portfolio.

We maintain depository investments with certain financial institutions. Although these depository investments may exceed government insured depository limits, we have evaluated the creditworthiness of these financial institutions and determined the risk of material financial loss due to exposure of such credit risk to be minimal. As of June 30, 2022, $40.7 million of our cash and cash equivalents, primarily certain domestic money market funds and foreign depository accounts, were in excess of government provided insured depository limits.

As of June 30, 2022, approximately $30.6 million of our cash and investments may be directly affected by changes in interest rates. As of June 30, 2022, we held $1.9 million of cash and variable-rate investments where a change in interest rates would impact our interest income. A hypothetical 50 basis point decline in interest rates as of June 30, 2022, assuming all other variables remain constant, would reduce annualized interest income on our cash and investments by less than $0.1 million. In addition, we held $28.7 million of fixed-rate bonds whose fair values may be directly affected by a change in interest rates. A hypothetical 50 basis point increase in interest rates as of June 30, 2022, assuming all other variables remain constant, would reduce the fair value of our fixed-rate bonds by approximately $0.3 million.

We are exposed to changes in foreign currency exchange rates to the extent that such changes affect our revenue and gross margin on revenue derived from some international customers, expenses, and assets and liabilities held in non-functional currencies related to our foreign subsidiaries. Our primary exposures to foreign currency exchange rate movements are with our European subsidiaries, whose functional currency is the Euro, our Australian subsidiary, whose functional currency is the Australian dollar, and our U.K. subsidiary, who transacts in the British pound sterling with a U.S. dollar functional currency. Our revenue is primarily denominated in the respective functional currency of the subsidiary and paid in that subsidiary’s functional currency or certain other local currency, our global supply chain predominately invoices us in the respective functional currency of the subsidiary and is paid in U.S. dollars and some of our operating expenses are invoiced and paid in certain local currencies (approximately 10.1% of total operating expense for the three and six months ended June 30, 2022). Therefore, our revenues, gross margins, operating expense and operating income are all subject to foreign currency fluctuations. As a result, changes in currency exchange rates could cause variations in our operating income.

We have certain customers and suppliers who are invoiced or pay in a non-functional currency. Changes in the monetary exchange rates used to invoice such customers versus the functional currency of the entity billing such customers may adversely affect our results of operations and financial condition. To manage the volatility relating to these typical business exposures, we may enter into various derivative transactions, when appropriate. We do not hold or issue derivative instruments for trading or other speculative purposes. For balances as of June 30, 2022, all non-functional currencies billed would result in a combined hypothetical gain or loss of $6.5 million if the U.S. dollar weakened or strengthened 10% against the billing currencies. All non-functional currencies invoiced by suppliers would result in a combined hypothetical gain or loss of $2.4 million if the U.S. dollar weakened or strengthened 10% against the billing currencies. This change represents an increase in the amount of hypothetical gain or loss compared to prior periods and is mainly due to an increase in U.S. dollar denominated billings in a non-U.S. dollar denominated subsidiary. Although we do not currently hold any derivative instruments, any gain or loss would be partially mitigated by any derivative instruments held.

As of June 30, 2022, we had certain material contracts subject to currency revaluation, including accounts receivable, accounts payable and lease liabilities, denominated in foreign currencies. As of June 30, 2022, we did not have any forward contracts outstanding.

For further information about the fair value of our investments as of June 30, 2022, see Note 6 of the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the rules and forms promulgated by the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Because of the inherent limitations to the effectiveness of any system of disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that all control issues, if any, with a company have been prevented or detected on a timely basis. Even disclosure controls and procedures determined to be effective can only provide reasonable assurance that their objectives are achieved.

As of the end of the period covered by this report, an evaluation was carried out by management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Exchange Act. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting.

There were no changes in the Company’s internal control over financial reporting that occurred during the most recent fiscal quarter covered by this report that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.

ITEM 1A. RISK FACTORS

A list of factors that could materially affect our business, financial condition or operating results is described in Part I, Item 1A, “Risk Factors” in the 2021 Form 10-K. There have been no material changes to our risk factors from those disclosed in Part I, Item 1A, “Risk Factors” in the 2021 Form 10-K, other than as described in the risk factors below.

We may fail to realize the anticipated strategic and financial benefits sought from the Business Combination.

We may not realize all of the anticipated benefits of the Business Combination. The success of the Business Combination will depend on, among other things, our ability to combine our business with ADVA’s business in a manner that facilitates growth as a provider of fiber networking solutions and realizes anticipated cost savings. We believe that the Business Combination will provide an opportunity for revenue growth in optical transport solutions, fiber access solutions and subscriber solutions.

However, we must successfully combine the business in a manner that permits these anticipated benefits to be realized. In addition, we must achieve the anticipated growth and cost savings without adversely affecting current revenues and investments in future growth. Further, providing integrated fiber networking solutions can be highly complex and can involve the design, development, implementation and operation of new solutions and the transitioning of clients from traditional platforms to new platforms. If we are not able to effectively provide different solutions and successfully achieve the growth and cost savings objectives, the anticipated benefits of the Business Combination may not be realized fully, or at all, or may take longer to realize than expected.

We may experience operational challenges, negative synergies and loss of customers.

Integrating the operations and personnel of the ADTRAN and ADVA businesses involves complex operational, technological and personnel-related challenges. This process will be time-consuming and expensive, and it may disrupt our business. Difficulties in the integration of the business, which may result in significant costs and delays, include:

•

managing a significantly larger company;

•

integrating and unifying the offerings and services available to customers and coordinating distribution and marketing efforts;

•

coordinating corporate and administrative infrastructures and harmonizing insurance coverage;

•

unanticipated issues in coordinating accounting, information technology, communications, administration and other systems;

•

difficulty addressing possible differences in corporate cultures and management philosophies;

•

challenges associated with changing ADVA's financial reporting from IFRS to accounting principles generally accepted in the U.S. (U.S GAAP) and compliance with the Sarbanes-Oxley Act of 2002, as amended, and the rules promulgated thereunder by the SEC;

•

legal and regulatory compliance;

•

creating and implementing uniform standards, controls, procedures and policies;

•

litigation relating to the transactions contemplated by a reorganization, including shareholder litigation;

•

diversion of management’s attention from other operations;

•

maintaining existing agreements and relationships with customers, distributors, providers and vendors and avoiding delays in entering into new agreements with prospective customers, distributors, providers and vendors;

•

realizing the benefits from our restructuring programs;

•

unforeseen and unexpected liabilities related to the Business Combination, including the risk that certain executive officers may be subject to additional fiduciary duties and liability;

•

identifying and eliminating redundant and underperforming functions and assets;

•

effecting actions that may be required in connection with obtaining regulatory approvals; and

•

a deterioration of credit ratings.

The Company may lose customers or its share of customers’ business as entities that were customers of both ADTRAN and AVDA seek to diversify their suppliers of services and products.

We have agreed to enter into negotiations regarding the conclusion of a domination agreement or a domination and profit and loss transfer agreement within the meaning of Sec. 291 para. 1 of the German Stock Corporation Act (Aktiengesetz) (a “DPLTA”), between ADVA, as the dominated entity, and ADTRAN (or a to-be-established subsidiary of ADTRAN), as dominating entity. If we pursue a DPLTA but the approval of such agreement is contested or its effectiveness is delayed as a result of litigation or otherwise or does not occur, we may be unable to initiate any transactions or measures that are disadvantageous to ADVA unless we provide adequate compensation to ADVA. If the disadvantage caused by any transaction or other measure cannot be assessed or compensated, we will be prohibited from initiating such transaction or measure. Accordingly, the lack of a DPLTA may preclude us from implementing certain transactions related to the integration of ADVA with our business, including realizing synergies. The failure to realize synergies may lead to a decline of the value of our shares.

Furthermore, if entry into a DPLTA with ADVA is delayed or does not occur, we will be prevented from increasing the aggregate principal amount available under our credit agreement with Wells Fargo Bank. This lack of access to additional capital could have a material adverse effect on our financial condition.

We may enter into a DPLTA with ADVA, which may have a material adverse effect on our financial results and condition.

In the event that we are able to enter into a DPLTA with ADVA, the DPLTA would allow us to issue binding instructions to the management board of ADVA, which could be disadvantageous to ADVA and result in a decline in the business and earnings power of ADVA. This could have a material adverse effect on the assets, financial position and income of ADVA, which in turn could have a material adverse effect on our financial condition.

Furthermore, pursuant to Sections 302 et seq. of the German Stock Corporation Act, under a DPLTA, we would be obligated to compensate any annual net loss of ADVA. Further, each ADVA shareholder who did not tender in the Exchange Offer would be offered to elect either (1) to remain an ADVA shareholder and receive, in the case of a domination agreement, an adequate fixed or variable annual guaranteed dividend (Garantiedividende) or, in the case of a domination and profit and loss transfer agreement, receive annual recurring compensation (Ausgleich) pursuant to Section 304 of the German Stock Corporation Act, or (2) to receive adequate exit compensation in exchange for its ADVA shares pursuant to Section 305(2) of the German Stock Corporation Act. Shareholders electing the first option may later elect the second option for as long as the offer for the exit compensation is open. Our obligation to pay an adequate fixed or variable annual guaranteed dividend or annual recurring compensation would lead to a continuing payment obligation. The amount of this continuing payment obligations pursuant to a DPLTA could exceed the amount of dividends that otherwise might be distributed by ADVA to minority shareholders and would even have to be paid if ADVA incurs losses, which could have a material adverse impact on our financial results and financial condition.

We are exposed to additional litigation risk and uncertainty with respect to the remaining minority shareholders of ADVA.

As a result of the Business Combination, we continue to be exposed to litigation risk and uncertainty associated with the remaining minority shareholders of ADVA. Our willingness and/or ability to acquire all issued and outstanding shares of ADVA, and the timing of any such potential acquisition, is uncertain. In addition, the terms of a DPLTA, if we enter into one with ADVA, including the adequacy of compensation payments to minority shareholders that maybe agreed to under the terms of a DPLTA, is likely to be challenged by minority shareholders of ADVA by initiating court-led appraisal proceedings under German law. We cannot rule out that the competent court in such appraisal proceeding may adjudicate higher exit compensation or recurring payment obligations (in each case, including interest thereon) than agreed upon in a DPLTA, the financial impact and timing of which is uncertain.

Negative publicity related to integration measures may adversely affect us.

Political and public sentiment in connection with the Business Combination and associated post-closing integration measures may result in a significant amount of adverse press coverage and other adverse public statements affecting the parties to the Business Combination. Adverse press coverage and public statements, whether or not driven by political or popular sentiment, may also result in legal claims or in investigations by regulators, legislators and law enforcement officials. Responding to these investigations and lawsuits, regardless of the ultimate outcome of the proceedings, can divert the time and effort of senior management from operating the business. Addressing any adverse publicity, governmental scrutiny or enforcement or other legal proceedings could be time-consuming and expensive and, regardless of the factual basis for the assertions being made, could have a negative impact on the reputation of the Company, ADVA and ADTRAN, Inc., on the morale and performance of their employees and on the relationships with regulators, suppliers and customers. It may also have a negative impact on our ability to take timely advantage of various business and market opportunities. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on the Company’s businesses and cash flows, financial condition and results of operations

We have incurred and expect to continue to incur significant transaction fees and costs in connection with the Business Combination and post-closing integration efforts.

We have incurred and expect to continue to incur a number of significant non-recurring implementation and restructuring costs associated with combining the operations of ADTRAN and ADVA. In addition, we have incurred significant banking, legal, accounting and other transaction fees and costs related to the Business Combination. As of June 30, 2022, we have incurred $8.7 million of transaction costs related to the Business Combination and expect to incur an estimated $14.9 million of additional transaction costs related to the Business Combination.

Additional costs substantially in excess of currently anticipated costs may also be incurred in connection with the integration of the businesses of ADTRAN and ADVA.

Any cost savings or other efficiencies related to the integration of the businesses that could offset these transaction- and combination-related costs over time may not be achieved in the near term, or at all. In addition, the timeline in which cost savings are expected to be realized is lengthy and may not be achieved. Failure to realize these synergies and cost reductions and other efficiencies in a timely manner or at all could have a material adverse effect on our business and cash flows, financial condition and results of operations.

Subsequent to the closing of the Business Combination, we entered into a new credit facility providing for borrowings of up to $100 million subject to being increased up to $400 million, and under which we have currently incurred $50.0 million amount of indebtedness. Our increased indebtedness could adversely affect our operations and liquidity. Our level of indebtedness could, among other things:

•

make it more difficult for us to pay or refinance our debts as they become due during adverse economic and industry conditions because we may not have sufficient cash flows to make its scheduled debt payments;

•

cause us to use a larger portion of our cash flow to fund interest and principal payments, reducing the availability of cash to fund working capital, capital expenditures, research and development and other business activities;

•

limit our ability to take advantage of significant business opportunities, such as acquisition opportunities, and to react to changes in market or industry conditions;

•

cause us to be more vulnerable to general adverse economic and industry conditions;

•

cause us to be disadvantaged compared to competitors with less leverage; and

•

limit our ability to borrow additional money in the future to fund working capital, capital expenditures, research and development and other general corporate purposes.

Our ability to satisfy our debt obligations and renew the credit facility is dependent upon our future performance and other risk factors discussed in this section. However, there can be no assurance that we will be able to manage any of these risks successfully. In addition, the credit agreement governing our indebtedness contain restrictive covenants that limit our ability to engage in activities that may be in our long-term best interest. Our failure to comply with those covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all its debt.

We may also incur additional long-term debt and working capital lines of credit to meet future financing needs, which would increase our total indebtedness. Although the terms of its existing and future credit agreements and of the indentures governing its debt contain restrictions on the incurrence of additional debt, including secured debt, these restrictions are subject to a number of important exceptions and debt incurred in compliance with these restrictions could be substantial. If we or our restricted subsidiaries incur significant additional debt, the related risks that we face could intensify.

Risks relating to the businesses of ADVA may have a significant adverse impact on our business and financial performance.

Due to the size and geographic reach of our operations following the completion of the Business Combination, a wide range of factors could materially affect our operations and financial performance. In addition to the risks described herein, the risks relating to ADVA’s business described in ADVA’s Risk and Opportunity Report under the Combined Management Report in ADVA’s 2021 Annual Report and 2022 6M Report, which can be found at https://www.adva.com/en/about-us/investors/financial-results/financial-reports, may significantly impact our business and financial performance.

We may be unable to successfully retain and motivate our personnel, including personnel at ADVA.

The success of the Business Combination will depend, in part, on our ability to retain the talents and dedication of key employees, including key decision-makers, currently employed by ADTRAN, Inc. and ADVA. Such employees may decide not to remain with us as a result of the Business Combination. If key employees terminate their employment, or if an insufficient number of employees are retained to maintain effective operations, our business activities may be adversely affected and management’s attention may be diverted from successfully integrating ADTRAN and ADVA to hiring suitable replacements, all of which may cause our business to deteriorate. We may not be able to locate suitable replacements for any key employees who leave or offer employment to potential replacements on reasonable terms. In addition, we may not be able to motivate certain key employees due to organizational changes, reassignments of responsibilities, the perceived lack of appropriate opportunities for advancement or other reasons. If we fail to successfully retain and motivate the employees of ADTRAN and/or ADVA, relevant capabilities and expertise may be lost which may have an adverse effect on our cash flows, financial condition, results of operations and the business operations in general.

The terms of the credit agreement restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.

The credit agreement contains a number of restrictive covenants that impose significant operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interest, including restrictions on our ability to:

•

incur additional indebtedness and guarantee indebtedness;

•

pay dividends or make other distributions or repurchase or redeem capital stock;

•

prepay, redeem or repurchase certain debt;

•

issue certain preferred stock or similar equity securities;

•

make loans and investments;

•

sell assets;

•

incur liens;

•

enter into transactions with affiliates;

•

alter the businesses we conduct; and

•

consolidate, merge or sell all or substantially all of our assets.

In addition, the restrictive covenants in the credit agreement governing our senior credit facility require us to maintain specified financial ratios and satisfy other financial condition tests. Our ability to meet those financial ratios and tests can be affected by events beyond our control, and we may be unable to meet them.

A breach of the covenants or restrictions under the credit agreement governing our senior credit facility could result in an event of default. Such a default may allow the creditors to accelerate the related debt and may result in the acceleration of any other debt to which a cross-acceleration or cross-default provision applies. In addition, an event of default under the credit agreement governing our senior credit facility would permit the lenders under our senior credit facility to terminate all commitments to extend further credit under that facility. Furthermore, if we were unable to repay the amounts due and payable under our senior credit facility, those lenders could proceed against the collateral granted them to secure that indebtedness. In the event our lenders or noteholders accelerate the repayment of our borrowings, we and our subsidiaries may not have sufficient assets to repay that indebtedness. As a result of these restrictions, we may be:

•

limited in how we conduct our business;

•

unable to raise additional debt or equity financing to operate during general economic or business downturns; and

•

unable to compete effectively or to take advantage of new business opportunities.

These restrictions may affect our ability to grow in accordance with our strategy. In addition, our financial results, our substantial indebtedness and our credit ratings could adversely affect the availability and terms of our financing.

As part of our business strategy, including and in addition to the acquisition of a majority equity stake in ADVA upon the closing of the Exchange Offer, we frequently engage in discussions with third parties regarding possible investments, acquisitions, strategic alliances, joint ventures, divestitures and outsourcing arrangements, and we enter into agreements relating to such transactions in order to further our business objectives. In order to pursue this strategy successfully, we must identify suitable candidates, successfully complete transactions, some of which may be large and complex, and manage post-closing issues such as the integration of acquired companies or employees and the divestiture of combined businesses, operations and employees. Integration, divestiture and other risks of these transactions can be more pronounced in larger and more complicated transactions, or if multiple transactions are pursued simultaneously. If we fail to identify and successfully complete transactions that further our strategic objectives, we may be required to expend resources to develop products and technology internally. This may put us at a competitive disadvantage and we may be adversely affected by negative market perceptions, any of which may have a material adverse effect on our revenue, gross margin and profitability.

Integration and divestiture issues are complex, time-consuming and expensive and, without proper planning and implementation, could significantly disrupt our business. The challenges involved in integrating and divesting include:

•

combining service and product offerings and entering into new markets in which we are not experienced;

•

convincing customers and distributors that any such transaction will not diminish client service standards or business focus, preventing customers and distributors from deferring purchasing decisions or switching to other suppliers or service providers (which could result in additional obligations to address customer uncertainty), and coordinating service, sales, marketing and distribution efforts;

•

consolidating and rationalizing corporate information technology infrastructure, which may include multiple legacy systems from various acquisitions and integrating software code;

•

minimizing the diversion of management attention from ongoing business concerns;

•

persuading employees that business cultures are compatible, maintaining employee morale and retaining key employees, integrating employees into our company, correctly estimating employee benefit costs and implementing restructuring programs;

•

coordinating and combining administrative, service, manufacturing, research and development and other operations, subsidiaries, facilities and relationships with third parties in accordance with local laws and other obligations while maintaining adequate standards, controls and procedures;

•

our responsibility for the liabilities of the businesses we acquire, some of which we may not anticipate, including costs of third-party advisors to resolve disputes;

•

achieving savings from supply chain and administration integration; and

•

efficiently divesting combined business operations which may cause increased costs as divested businesses are de-integrated from embedded systems and operations.

We evaluate and enter into these types of transactions on an ongoing basis. We may not fully realize all of the anticipated benefits of any transaction and the time frame for achieving benefits of a transaction may depend partially upon the actions of employees, suppliers or other third parties. In addition, the pricing and other terms of our contracts for these transactions require us to make estimates and assumptions at the time we enter into these contracts, and, during the course of our due diligence, we may not identify all of the factors necessary to estimate costs accurately. Any increased or unexpected costs, unanticipated delays or failure to achieve contractual obligations could make these agreements less profitable or unprofitable.

Managing these types of transactions requires varying levels of management resources, which may divert our attention from other business operations. These transactions could result in significant costs and expenses and charges to earnings, including those related to severance pay, early retirement costs, employee benefit costs, asset impairment charges, charges from the elimination of duplicative facilities and contracts, in-process research and development charges, inventory adjustments, assumed litigation, regulatory compliance and other liabilities, legal, accounting and financial advisory fees and required payments to executive officers and key employees under retention plans. Moreover, we could incur additional depreciation and amortization expense over the useful lives of certain assets acquired in connection with these transactions, and, to the extent that the value of goodwill or intangible assets with indefinite lives acquired in connection with a transaction becomes impaired, we may be required to incur additional material charges relating to the impairment of those assets. In order to complete an acquisition, we may issue common shares, potentially creating dilution for existing shareholders, or borrow funds, which could affect our financial condition, results of operations and potentially our credit ratings. Any prior or future downgrades in our credit rating associated with a transaction could adversely affect our ability to borrow and our borrowing cost, and result in more restrictive borrowing terms. In addition, our effective tax rate on an ongoing basis is uncertain, and such transactions could impact our effective tax rate. We also may experience risks relating to the challenges and costs of closing a transaction and the risk that an announced transaction may not close. As a result, any completed, pending or future transactions may contribute to financial results that differ materially from the investment community’s expectations.

We expect gross margins to vary over time, and our levels of product and services gross margins may not be sustainable.

Our level of gross margins may not be sustainable and has been and may continue to be adversely affected by numerous factors, including:

•

changes in customer, geographic or product or services mix, including software and the mix of configurations and professional services revenue within each product segment;

•

mix of domestic versus international revenue;

•

introduction of new products by competitors, including products with price-performance advantages;

•

our ability to reduce product cost;

•

increases in labor or material cost, including increases in material costs resulting from inflation or tariffs;

•

foreign currency exchange rate movements;

•

expediting costs incurred to meet customer delivery requirements;

•

excess inventory and inventory holding charges;

•

excess and obsolescence charges;

•

changes in shipment volume;

•

our ability to absorb fixed manufacturing costs during short-term fluctuations in customer demand;

•

loss of cost savings due to changes in component pricing or charges incurred due to inventory holding periods if parts ordering does not correctly anticipate product demand;

•

lower than expected benefits from value engineering;

•

increased price competition, including competitors from Asia, specifically China;

•

changes in distribution channels;

•

increased warranty cost;

•

liquidated damages costs relating to customer contractual terms;

•

our ability to manage the impact of foreign currency exchange rate fluctuations relating to our revenue or cost of revenue;

•

slowdowns, recessions, economic instability, political unrest, armed conflicts (such as the ongoing military conflict in Ukraine), or outbreaks of disease, such as the COVID-19 pandemic, around the world; and

•

Business Combination purchase price allocations.

For example, since the third quarter of 2021 and continuing to date into 2022, we have incurred and may continue to incur supply chain constraint expenses, including price inflation for certain electronic components, semiconductor chips and transportation related costs, which have lowered our gross margins and decreased our profitability.

We are heavily dependent on subcontractors for the assembly and testing of certain printed circuit board assemblies, subassemblies, chassis, enclosures and equipment shelves, and the purchase of some raw materials used in such assemblies. This reliance involves several risks, including the unavailability of, or interruptions in, access to certain process technologies and reduced control over product quality, delivery schedules, transportation, manufacturing yields and costs. We may not be able to provide product order volumes to our subcontractors that are high enough to achieve sufficient cost savings. If shipments fall below forecasted levels, we may incur increased costs or be required to take ownership of excess inventory. Changes in international tariff structures could adversely impact our product costs. We also have experienced and expect to continue to experience increased inflationary pressures on input costs, such as, raw materials, labor and distribution costs. Our attempts to offset these cost pressures, such as through increases in the selling prices of some of our products and services, may not be successful and could negatively affect our operating results. In addition, a significant component of maintaining cost competitiveness is the ability of our subcontractors to adjust their costs to compensate for possible adverse exchange rate movements. To the extent that the subcontractors are unable to do so, and we are unable to procure alternative product supplies, then our competitiveness and results of operations could be adversely impaired. These risks may be exacerbated by economic, regulatory or political changes or uncertainties, terrorist actions, acts of war, the effects of climate change, natural disasters or pandemics in the foreign countries in which our subcontractors are located. We do not utilize contract manufacturing for our products in China, though we do source some ODM products from China which are, or may become, subject to import tariffs.

To date, we believe that we have successfully managed the risks of our dependence on these subcontractors through a variety of efforts, which include seeking and developing alternative subcontractors while maintaining existing relationships; however, we cannot be assured that delays in product deliveries will not occur in the future because of shortages resulting from this limited number of subcontractors or from the financial or other difficulties of these parties. Our inability to develop alternative subcontractors if and as required in the future, or the need to undertake required retraining and other activities related to establishing and developing a new subcontractor relationship, could result in delays or reductions in product shipments which, in turn, could have a negative effect on our customer relationships and operating results.

Certain raw materials and key components used in our products are currently available from only one source, and others are available from only a limited number of sources. The availability of these raw materials and supplies may be subject to market forces beyond our control, such as inflation, merger and acquisition activity of our suppliers and consolidation in some segments of our supplier base. We have experienced and expect to continue to experience increased inflationary pressures on input costs, such as, raw materials, supplies, labor and distribution costs to increase. Our attempts to offset these cost pressures, through increases in the selling prices of some of our products, may not be successful and could negatively affect our operating results. In addition, from time to time, there may not be sufficient quantities of raw materials and supplies in the marketplace to meet customer demand. For example, wafer foundries that support chipmakers have not invested enough in recent years to increase capacities to the levels need to support demand from all of their customers and wafers have a long lead time for production, in some cases up to 30 weeks, which has led to a recent shortage in chip supplies. Many companies utilize the same raw materials and supplies that we do in the production of their products. Companies with more resources than our own may have a competitive advantage in obtaining raw materials and supplies due to greater buying power. These factors have resulted in reduced supply, higher prices of raw materials and delays in the receipt of certain of our key components, which in turn has generated increased costs, lower margins and delays in product delivery, with a corresponding adverse effect on revenue. Delays in product deliveries and corresponding product price increases may likewise have an adverse effect on customer relationships. We attempt to manage these risks through developing alternative sources, by staging inventories at strategic locations, through engineering efforts designed to obviate the necessity of certain components and by building long-term relationships and close contact with each of our key suppliers; however, we cannot assure that delays in or failures of deliveries of key components, either to us or to our contract manufacturers, and consequent delays in product deliveries, will not continue to occur in the future. In addition, our supply chain challenges are forcing us to devote a substantial portion of our research and development expenses to redesign existing products, reducing our capacity to develop new products. For a discussion of the impact of the COVID-19 pandemic on our supply chain, see “- The ongoing COVID-19 pandemic has impacted and may continue to impact our business, results of operations and financial condition, particularly our supply chain and workforce.”

The continuing growth of our international operations could expose us to additional risks, increase our costs and adversely affect our operating results, financial condition and cash flows.

We are expanding our presence in international markets, which represented 38.5% and 33.9% of our net revenue for the three months ended June 30, 2022 and 2021, and 37.3% and 33.1% of our revenue for the six months ended June 30, 2022 and 2021, respectively, and as a result, we anticipate increased revenue and operating costs in these markets. This international expansion has increased and may continue to increase our operational risks and impact our results of operations, including:

•

exposure to unfavorable commercial terms in certain countries;

•

the time and cost to staff and manage foreign operations, including the time and cost to maintain good relationships with employee associations and work councils;

•

exposure to unfavorable commercial terms in certain countries;

•

the time and cost to ensure adequate business interruption controls, processes and facilities;

•

the time and cost to manage and evolve financial reporting systems, maintain effective financial disclosure controls and procedures, and comply with corporate governance requirements in multiple jurisdictions;

•

the cost to collect accounts receivable and extension of collection periods;

•

the cost and potential disruption of facilities transitions required in some business acquisitions;

•

risks as a result of less regulation of patents or other safeguards of intellectual property in certain countries;

•

the potential impact of adverse tax, customs regulations and transfer-pricing issues;

•

exposure to increased price competition from additional competitors in some countries;

•

exposure to global social, political and economic instability, changes in economic conditions and foreign currency exchange rate movements;

•

potential exposure to liability or damage of reputation resulting from a higher incidence of corruption or unethical business practices in some countries;

•

potential regulations on data protection, regarding the collection, use, disclosure and security of data;

•

potential trade protection measures, export compliance issues, domestic preference procurement requirements, qualification to transact business and additional regulatory requirements;

•

potential exposure to natural disasters, epidemics and pandemics (and government regulations in response thereto) and acts of war or terrorism; and

•

potential exposure to ongoing military conflict in Ukraine. The U.S. and certain other countries imposed sanctions on Russia and could impose further sanctions against it, which could damage or disrupt international commerce and the global economy. Other potential consequences include, but are not limited to, growth in the number of popular uprisings in the region, increased political discontent, especially in the regions most affected by the conflict or economic sanctions, displacement of persons to regions close to the areas of conflict and an increase in the number of refugees, among other unforeseen social and humanitarian effects which could impact our business, customers, and suppliers.

If we are unable to successfully address the potential risks associated with our overall international expansion, our operating results, financial condition and cashflows may be negatively impacted.

We are exposed to adverse currency exchange rate fluctuations in jurisdictions where we transact in local currency, which could harm our financial results and cash flows.

We are exposed to changes in foreign currencies relative to the U.S. dollar, which are references to the differences between the foreign-exchanges rates we use to convert the financial results of our international operations from local currencies into U.S. dollars for financial reporting purposes. This impact of foreign-exchange rate changes is calculated based on the difference between the current period’s currency exchange rates and that of the comparable prior period. Our primary exposures to foreign currency exchange rate movements are with our German subsidiaries, whose functional currency is the Euro, our Australian subsidiary, whose functional currency is the Australian dollar, and our U.K. subsidiary, who transacts in the British pound sterling with a U.S. dollar functional currency. As a result of our global operations, our revenue, gross margins, operating expense and operating income in some international markets have been and may continue to be affected by foreign currency fluctuations.

Breaches of our information systems and cyber-attacks could compromise our intellectual property and cause significant damage to our business and reputation.

We maintain sensitive data on our information systems and the networks of third-party providers, including intellectual property, financial data and proprietary or confidential business information relating to our business, customers, suppliers, and business partners. We also produce networking equipment solutions and software used by network operators to ensure security and reliability in their management and transmission of data. Our customers, particularly those in regulated industries, are increasingly focused on the security features of our technology solutions. Maintaining the security of information sensitive to us and our business partners is critical to our business and reputation. We rely upon several internal business processes and information systems to support key operations and financial functions, and the efficient operation of these processes and systems is critical. Companies are increasingly subjected to cyber-attacks and other attempts to gain unauthorized access. We have a comprehensive approach to cybersecurity, which includes prevention, detection, containment, and response. Our layered defense approach encompasses proactive security monitoring of our global infrastructure by both internal solutions and multiple third-party Security Operation Centers. Additionally, we routinely perform patch management, vulnerability scans, penetration tests and continuous monitoring across our entire enterprise. Our security policy framework includes meaningful and enforceable Information Security policies and procedures. The cybersecurity program is aligned with our mission and business objectives, reviewed periodically for improvements, and is supported by experienced and certified security professionals. This is supplemented by an information security awareness program spanning our global workforce. Despite this, our network and storage applications and those systems and applications maintained by our third-party providers may be targeted by cyber-attacks or potentially breached due to operator error, fraudulent activity, or other system disruptions. For example, although we did not identify indicators of compromise in response to the Log4j2.x vulnerability, we cannot absolutely assure that future vulnerabilities or malware attacks will not be successful in breaching our system and in turn, materially impact our business. Unauthorized access or disclosure of our information could compromise our intellectual property and expose sensitive business information. Our information systems are designed to appropriate industry standards and resiliently engineered to reduce downtime in the event of power outages, weather or climate events and cybersecurity issues. These risks, as well as the number and frequency of cybersecurity events globally, may also be heightened during times of geopolitical tension or instability between countries, including, for example, the ongoing military conflict in Ukraine, from which a number of recent cybersecurity events have been alleged to have originated. We carry cybersecurity insurance policies meant to limit our risk and exposure should one of these cybersecurity issues occur. However, a significant failure of our systems due to these issues could result in significant remediation costs, disrupt business operations, and divert management attention, which could result in harm to our business reputation, operating results, financial condition, and cash flows.

As part of our due diligence and integration planning process, the Company’s cybersecurity team has conducted a review of ADVA’s cybersecurity program. Additionally, prior to any integration of facilities, networks, or systems, we expect to conduct an enterprise-wide vulnerability assessment to determine if additional security measures are required. As part of the integration plan, the Company intends to expand its current cybersecurity program to cover all ADVA’s global infrastructure and adopt any mature cybersecurity practices already in place. A significant failure of our review and integration of ADVA's cybersecurity program could expose us to penalties for failing to comply with the E.U.'s General Data Protection Regulation as well as result in significant remediation costs and a disruption to our operations.
