1. Nature of Business and Basis of Presentation

Casa Systems, Inc. (the “Company”) was incorporated under the laws of the State of Delaware on February 28, 2003. The Company is a global communications technology company headquartered in Andover, Massachusetts and has wholly owned subsidiaries in China, France, Canada, Ireland, Spain, ~~Colombia,~~ the Netherlands, Hong Kong, Australia, Germany, the United Kingdom and New Zealand.

The Company offers physical, virtual and cloud-native 5G ~~broadband~~infrastructure and customer premise networking equipment ~~for~~solutions to help CSPs transform and expand their public and private high-speed data and multi-service communications ~~networks.~~networks so they can meet the growing demand for bandwidth and new services. The Company’s core and edge broadband technology enables ~~communications service providers~~CSPs and enterprises to cost-effectively and dynamically increase data network speed, add bandwidth capacity and new services, reduce network complexity and reduce operating and capital ~~expenditures.~~ expenditures regardless of access technology.

The Company is subject to a number of risks similar to other companies of comparable size and other companies selling and providing services to the ~~communications service provider (“CSP”)~~CSP industry. These risks include, but are not limited to, the level of capital spending by ~~the~~ CSPs, a lengthy sales cycle, dependence on the development of new products and services, unfavorable economic and market conditions, competition from larger and more established companies, limited management resources, dependence on a limited number of contract manufacturers and suppliers, the rapidly changing nature of the technology used by ~~the~~ CSPs and reliance on resellers and sales agents. Failure by the Company to anticipate or to respond adequately to technological developments in its industry, changes in customer or supplier requirements, changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of products could have a material adverse effect on the Company’s operating results, financial condition and cash flows.

Management believes the existing cash and cash equivalents and anticipated cash flows from future operations will be sufficient to meet its working capital and capital expenditure needs and debt service obligations for at least the next 12 months. As described in Note 9 "Debt", the Company's outstanding term loan facility is scheduled to mature in December 2023, and it has commenced the refinancing process. If the Company is unable to successfully complete a refinancing of a sufficient portion of the outstanding balance prior to maturity or otherwise satisfy its repayment obligations, there may be substantial doubt about its ability to continue as a going concern beyond the maturity date of the loan.

The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and may remain an emerging growth company until the last day of the fiscal year following the fifth anniversary of the Company’s initial public offering, subject to specified conditions. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected not to “opt out” of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company is required to adopt the new or revised standard at or prior to the time private companies are required to adopt the new or revised standard, provided that the Company continues to be an emerging growth company. The JOBS Act provides that the decision to take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable. The Company will remain an emerging growth company until December 31, 2022.

The accompanying condensed consolidated balance sheet as of September 30, ~~2021,~~2022, the condensed consolidated statements of operations and comprehensive (loss) income for the three and nine months ended September 30, ~~2021~~2022 and ~~2020,~~2021, the condensed consolidated statements of cash flows for the nine months ended September 30, ~~2021~~2022 and ~~2020~~2021 and the condensed consolidated statements of stockholders’ equity for the three and nine months ended September 30, ~~2021~~2022 and ~~2020~~2021 are unaudited. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, ~~2021~~2022 and ~~2020~~2021 are also unaudited. The accompanying condensed consolidated balance sheet as of December 31, ~~2020~~2021 was derived from the Company’s audited consolidated financial statements for the year ended December 31, ~~2020~~2021 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 25, ~~2021~~2022 (the “Annual Report on Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted ~~accounting principles~~ in the United States of America (“GAAP”) regarding interim financial reporting. Certain information and note disclosures normally included in the

consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report on Form 10-K. There have been no changes to the Company’s accounting policies from those disclosed in the Annual Report on Form 10-K that would have a material impact on the Company’s condensed consolidated financial statements.

The unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and, in the opinion of management, include all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods, but are not necessarily indicative of the results of operations and cash flows to be anticipated for the full year ending December 31, ~~2021~~2022 or any future period.

The accompanying condensed consolidated financial statements include the accounts and results of operations of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods.

Significant estimates and judgments relied upon by management in preparing these condensed consolidated financial statements include revenue recognition, ~~provision for doubtful accounts,~~ reserves for excess and obsolete inventory, valuation of inventory and deferred inventory costs, the expensing and capitalization of software-related research and development costs, amortization and depreciation periods, the recoverability of net deferred tax assets, valuations of uncertain tax positions, warranty allowances, the valuation of equity instruments and stock-based compensation expense.

Although the Company regularly reassesses the assumptions underlying these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances existing at the time such estimates are made.

The COVID-19 pandemic presents various risks to the Company, ~~not all of which the Company is able to fully evaluate or even to foresee at the current time, and~~ which could continue to have a material effect upon the estimates and judgments relied upon by management in preparing these condensed consolidated financial statements. While the Company remains fully operational, during the three and nine months ended September 30, ~~2021,~~2022, the effects of the COVID-19 pandemic on the global supply chain had a significant adverse effect on the Company’s financial results. In particular, certain of the Company’s products utilize components, ~~for which there has been increased~~whose availability was significantly exceeded by global demand. As a result, ~~throughout 2021, and increasingly~~ during the three and nine months ended September 30, ~~2021,~~2022, the Company ~~began~~continued to see shortages of supply that resulted in the Company’s inability to fulfill certain customer orders within normal lead times. This adversely impacted the Company’s revenue and operating results for the three and nine months ended September 30, ~~2021.~~2022. Additionally, shipping bottlenecks and delays negatively affected the Company’s ability to timely fulfill customer orders, thereby delaying its ability to consummate sales and recognize revenue. The Company also experienced, in some cases, significant increases in shipping costs. While the Company continues to work with its supply chain, contract manufacturers, logistics partners, and customers to minimize the extent of such impacts, the Company expects the effects of global supply chain issues to continue and cannot predict when such effects will subside. This may prevent the Company from being able to fulfill its customers’ orders in a timely manner or at all, which could lead to one or more of its customers cancelling their orders.

In addition, the regions in which the Company operates have experienced a significant increase in inflation, which has adversely impacted the cost to manufacture the Company's products with limited ability to pass such increases on to its customers under previously established fixed price agreements. Inflation has further resulted in increased operating costs, and interest rate increases, which will result in increased debt service costs. If interest rates continue to rise the Company anticipates further adverse effects from inflation and increased interest rates.

At this time the Company is neither able to estimate the extent of these impacts nor predict whether its efforts to minimize or contain them will be successful. The Company intends to continue to monitor its business very closely for any effects of COVID-19, inflation and interest rate increases for as long as necessary.

Subsequent Event Considerations

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required, and other than the debt repurchase discussed in Note 17, “Subsequent Events”, the Company has determined that there are no other material recognized or unrecognized subsequent events requiring disclosure in these condensed consolidated financial statements.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include all highly liquid investments maturing within three months from the date of purchase. As of September 30, ~~2021~~2022 and December 31, ~~2020,~~2021, the Company’s cash and cash equivalents consisted of investments in ~~certificates of deposit and~~ money market mutual funds.

Restricted cash as of September 30, ~~2021~~2022 and December 31, ~~2020~~2021 consisted of a certificate of deposit of ~~$1,000 and $1,006, respectively,~~$1,008, pledged as collateral for a stand-by letter of credit required to support a contractual obligation. Restricted cash also included cash of $2,100 pledged as collateral in connection with five and two letters of credit to support contractual obligations at September 30, 2022 and December 31, 2021, respectively.

The following table is a reconciliation of cash, cash equivalents and restricted cash included in the accompanying condensed consolidated balance sheets that sum to the total cash, cash equivalents and restricted cash included in the accompanying condensed consolidated statements of cash flows:

Accounts Receivable

Accounts receivable are presented net of a provision for doubtful accounts, which is an estimate of amounts that may not be collectible. Accounts receivable for customer contracts with customary payment terms, which are one year or less, are recorded at invoiced amounts and do not bear interest. The Company may, in limited circumstances, grant payment terms longer than one year. Payments due beyond 12 months from the balance sheet date are recorded as non-current assets. The Company generally does not require collateral, but the Company may, in certain instances based on its credit assessment, require full or partial prepayment prior to shipment.

Accounts receivable as of September 30, ~~2021~~2022 and December 31, ~~2020~~2021 consisted of the following:


	September 30, 2021		December 31, 2020		September 30, 2022		December 31, 2021

	$	80,863	$	94,267	$	49,097	$	85,889

The Company performs ongoing credit evaluations of its customers and, if necessary, provides a provision for doubtful accounts and expected losses. When assessing and recording its provision for doubtful accounts, the Company evaluates the age of its accounts receivable, current economic trends, creditworthiness of the customer, customer payment history, and other specific customer and transaction information. The Company writes off accounts receivable against the provision when it determines a balance is uncollectible and no longer actively pursues collection of the receivable. Adjustments to the provision for doubtful accounts are recorded as selling, general and administrative expenses in the condensed consolidated statements of operations and comprehensive (loss) income.

As of September 30, ~~2021~~2022 and December 31, ~~2020,~~2021, the Company concluded that all amounts due under extended payment terms were collectible and 0recorded no reserve for credit ~~losses was recorded.~~losses. During the nine months ended September 30, ~~2021~~2022 and ~~2020,~~ 2021,

the Company did 0tnot provide a reserve for credit losses and did 0tnot write off any uncollectible receivables due under extended payment terms.

Concentration of Risks

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. Cash and cash equivalents consist of demand deposits, savings accounts, money market mutual funds, and certificates of deposit with financial institutions, which may exceed Federal Deposit Insurance Corporation limits. The Company has not experienced any losses related to its cash and cash equivalents and does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

The Company grants credit to customers in the ordinary course of business. Credit evaluations are performed on an ongoing basis to reduce credit risk, and no collateral is required from the Company’s customers. An allowance for uncollectible accounts is provided for those accounts receivable considered to be uncollectible based upon historical experience and credit evaluation. Due to these factors, no additional losses beyond the amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable.

Significant customers are those that represent 10% or more of revenue or accounts receivable and are set forth in the following tables:


	Revenue						Revenue						Revenue						Revenue
	Three Months Ended September 30,						Nine Months Ended September 30,						Three Months Ended September 30,						Nine Months Ended September 30,

Certain of the components and subassemblies included in the Company’s products are obtained and manufactured from a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those single or limited source suppliers, the partial or complete loss of certain of these sources could have a material adverse effect on the Company’s operating results, financial condition and cash flows and damage its customer relationships.

Inventories

~~Stock-Based Compensation~~

The Company ~~measures stock options and other stock-based awards granted to employees and directors based on~~values inventories at the ~~fair value on the date~~lower of ~~grant and recognizes compensation expense of those awards,~~cost or net ~~of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award.

The Company ~~issues stock options with only service-based vesting conditions and records the expense for these awards~~computes cost using the ~~straight-line method.~~

The Company ~~classifies stock-based compensation expense~~establishes provisions for excess and obsolete inventories after evaluating historical sales, future demand, market conditions, expected product life cycles, and current inventory levels to reduce such inventories to their estimated net realizable value. The Company makes such provisions in the normal course of business and charges them to cost of revenue in its consolidated statements of operations and comprehensive (loss) ~~income in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.~~income.

The Company recognizes compensation expense for only the portion of awards that are expected to vest. In developing a forfeiture rate estimate, the Company has considered its historical experience to estimate pre-vesting forfeitures for service-based awards. The impact of a forfeiture rate adjustment will be recognized in full in the period of adjustment, and if the actual forfeiture rate is materially different from the Company’s estimate, the Company may be required to record adjustments to stock-based compensation expense in future periods.

The Company estimates the fair value of each stock option grant on the date of grant using the Black-Scholes option pricing model. The Company was a private company until December 14, 2017 and lacks sufficient company-specific historical and implied volatility information for its stock. Therefore, for all options granted in 2020 or before, the Company estimated its expected stock volatility based on the historical volatility of publicly traded peer companies. Beginning with options granted in 2021, the Company estimates its expected stock volatility using a weighted-average calculation based on the historical volatility of the Company and publicly traded peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded stock price. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The expected term of stock options granted to non-employees is equal to the contractual term of the option award. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company does not have a history of declaring or paying cash dividends, except for the special cash dividends declared in November 2014, June 2016, December 2016, May 2017 and November 2017, and in those circumstances the board of directors approved cash dividends to be paid to holders of the Company’s stock options, stock appreciation rights (“SARs”) and restricted stock units (“RSUs”) upon vesting as an equitable adjustment to the holders of such instruments.

The Company has also granted SARs to certain employees, which require the Company to pay in cash upon exercise an amount equal to the product of the excess of the per share fair market value of the Company’s common stock on the date of exercise over the exercise price, multiplied by the number of shares of common stock with respect to which the SAR is exercised. Because these awards may require the Company to settle the awards in cash, the Company accounts for them as a liability in the Company’s consolidated balance sheets. The Company recognizes the liability related to these awards, as well as related compensation expense over the period during which services are rendered until completed. As all SARs are now fully vested, the Company continues to remeasure the fair market value of the liability until the award is either exercised or canceled, with changes in the fair value of the liability recorded in the consolidated statements of operations and comprehensive (loss) income.

Impact of Recently Adopted Accounting Standards

In ~~August 2020,~~October 2021, the ~~FASB~~Financial Accounting Standards Board, ("FASB"), issued ~~ASU 2020-06,~~ Accounting Standards Codification Update (“ASU”) 2021-08, ~~Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40)~~Business Combinations (Topic 805): Accounting for ~~Convertible Instruments~~Contract Assets and Contract Liabilities from Contracts with Customers, ("ASU 2021-08"). Under ASU 2021-08, an acquirer must recognize and measure contract assets and contract liabilities acquired in ~~an Entity’s Own Equity~~a business combination in accordance with Topic 606. Effective ~~. This guidance simplifies~~January 1, 2022, the ~~guidance~~Company early adopted ASU 2021-08 on ~~certain financial instruments with characteristics~~a prospective basis. The impact of liability and equity, including convertible debt instruments. As a result, entities will not separately present in equity an embedded conversion feature in such debt and will account for a convertible debt instrument wholly as debt, unless certain other conditions are met. The eliminationadoption of these models will reduce reported interest expense and increase reported net income for entities that have issued a convertible instrument that is within the scope of ASU 2020-06. The ASU also simplifies the diluted earnings per share calculation in certain areas. The guidance will become effective for fiscal years beginning after December 15, 2021, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. The Company has elected to early adopt this ~~ASU and the adoption did not have a material impact~~standard on the Company’s condensed consolidated financial statements ~~and the accompanying notes thereto.~~was not material.

Impact of Recently Issued Accounting Standards

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842): Amendments to FASB Accounting Standards Codification(“ ("ASU ~~2016-02”~~2016-02"), which replaces the existing guidance for leases. ASU 2016-02 requires the identification of arrangements that should be accounted for as leases by lessees. In general, for lease arrangements exceeding a twelve-month term, the arrangements must now be recognized as assets and liabilities on the balance sheet of the lessee. Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all leases, whether operating or financing, while the income statement will reflect lease expense for operating leases and amortization/interest expense for financing leases. The balance sheet amount recorded for existing leases at the date of adoption of ASU 2016-02 must be calculated using the applicable incremental borrowing rate at the date of adoption. This guidance will become effective for private companies, and emerging growth companies that choose to take advantage of the extended transition periods, for annual reporting periods beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company ~~has begun planning for adoption~~will begin reporting on topics required by ~~implementing a new lease accounting software and by working to establish additional changes to internal processes to comply with all requirements upon adoption.~~ASU 2016-02 during the fourth quarter of 2022.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“, or ASU ~~2016-13”).~~2016-13. This guidance is intended to provide more decision-useful information about expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The main provisions include presenting financial assets measured at amortized cost at the amount expected to be collected, which is net of an allowance for expected credit losses and recording credit losses related to available-for-sale securities through an allowance for credit losses. The effective dates for the amendments in ASU 2016-13 were updated in ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), and as such ASU 2016-13 will become effective for private companies, and emerging growth companies that choose to take advantage of the extended transition periods, for fiscal years beginning after December 15, 2022, including interim periods within those fiscal periods, and must be applied using a modified retrospective approach.

8~~. Derivative Instruments~~8. Income Taxes

The Company has certain international customers that are billed in foreign currencies. To mitigate the volatility related to fluctuations in the foreign exchange rates for accounts receivable denominated in foreign currencies, the Company enters into foreign currency forward contracts. As of September 30, 2021, the Company had foreign currency forward contracts outstanding with notional amounts totaling 1,379 Euros maturing in the fourth quarter of 2021 and the first quarter of 2022. As of December 31, 2020,~~0 foreign currency forward contracts were outstanding.~~

The Company’s ~~foreign currency forward contracts described above economically hedged certain risks but were not designated as hedges for financial reporting purposes,~~effective income tax rate was 3.9% and accordingly, all changes in the fair value of the derivative instruments were recorded as unrealized foreign currency transaction gains or losses and were included in the condensed consolidated statements of operations and comprehensive (loss) income as a component of other income (expense). The Company records derivative instruments in the condensed consolidated balance sheet at their fair values. As of September 30, 2021, the Company recorded an asset of $2485.8relating to outstanding foreign currency forward contracts. As of December 31, 2020 the Company recorded 0 asset relating to outstanding foreign currency forward contracts. As of September 30, 2021 and December 31, 2020, the Company recorded 0 liability relating to outstanding foreign currency forward contracts.

The Company also faces exposure to foreign currency exchange rate fluctuations, as a certain portion of its expenses are denominated in currencies other than U.S. dollars. In certain instances, the Company utilizes forward contracts to hedge against foreign currency fluctuations. These contracts are used to minimize foreign gains or losses, as the gains or losses on the derivative are intended to offset the losses or gains on the underlying exposure. The Company does not engage in foreign currency speculation.

The Company designed its foreign currency risk management strategy principally to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currencies resulting from changes in foreign currency exchange rates. The Company may enter into cash flow hedges that utilize foreign currency forward contracts to hedge specific forecasted transactions of its foreign subsidiaries with the goal of protecting its budgeted expenses against foreign currency exchange rate changes compared to its budgeted rates.

During the three months ended September 30, 2020, the Company settled one cash flow hedge with a notional amount of 5,000 AUD to hedge certain Australian dollar cash flows incurred during the period. The amount of gain reclassified from other comprehensive (loss) income% for the three months ended September 30, ~~2020~~2022 and 2021, respectively. The benefit from income taxes was ~~$527. The full amount of the fair value of the derivatives on the settlement date of $725 was recognized as $57 cost of goods sold, $353 research~~$1,261 and ~~development expense and $315 selling, general and administrative expense in the condensed consolidated statement of comprehensive (loss) income~~$5,288 for the three months ended September 30, ~~2020.~~

~~During the~~ ~~nine months ended September 30, 2020, the Company settled two cash flow hedges with notional amounts of 8,500 AUD~~2022 and 5,000 AUD to hedge certain Australian dollar cash flows incurred during the period. The amount of gain reclassified from other comprehensive (loss) income for the nine months ended September 30, 2020 was $752. The full amount of the fair value of the derivatives on the settlement date of $1,613 was recognized as $124 cost of goods sold, $890 research and development expense and $599 selling, general and administrative expense in the condensed consolidated statement of comprehensive (loss) income for the nine months ended September 30, 2020.

~~The Company did 0t have any cash flow hedges outstanding as of September 30,~~ 2021, ~~and December 31, 2020.~~

~~9. Income Taxes~~

The Company’s effective income tax rate was 85.8% and 40.9% for the three months ended September 30, 2021 and 2020, respectively. The (benefit from) provision for income taxes was $(5,288) and $2,399 for the three months ended September 30, 2021 and 2020, respectively. The change in the ~~(benefit from) provision for~~benefit from income taxes was primarily due to a discrete benefit of ~~($7,097)~~$(7,097) recorded in the three months ended September 30, 2021 related to ~~a change in estimate~~finalization of loss carrybacks associated with the ~~Company’s prior year net operating loss that is able to be carried back as part of the Coronavirus Aid, Relief and Economic Security Act (“~~CARES ~~Act”).~~Act. The change in the ~~(benefit from)~~benefit from income taxes was also impacted by changes in the jurisdictional mix of earnings.

The Company's effective income tax rate was (6.7%) and 11.6% for the nine months ended September 30, 2022 and 2021, respectively. The provision for income taxes was $5,071 and $220 for the nine months ended September 30, 2022 and 2021, respectively. The change in the provision from income taxes was impacted by a discrete benefit of $(7,097) recorded in the nine months ended September 30, 2021 related to loss carrybacks associated with the CARES Act. The change in the provision for income taxes was also impacted by the new requirement to capitalize and amortize all research and experimentation expenditures for U.S. tax purposes, pursuant to the Tax Cuts and Jobs Act (“TCJA”) as of January 1, 2022. This new requirement results in significant forecasted U.S. current income tax for 2022 and the corresponding deferred tax asset created is offset by a full valuation allowance. The change in the provision for income taxes was also impacted by changes in the jurisdictional mix of earnings ~~period over period.~~and the valuation allowance maintained against our deferred tax assets.

The Company’s effective income tax rate was 11.6% and 142.0% for the nine months ended September 30, 2021 and 2020, respectively. The provision for (benefit from) income taxes was $220 and $(5,433) for the nine months ended September 30, 2021 and 2020, respectively. The change in the provision for (benefit from) income taxes was primarily due to a discrete tax benefit of $ (9,310) recorded during the nine months ended September 30, 2020 associated with the enactment of the CARES Act, partially offset by a discrete benefit of ($7,097) recorded during the nine months ended September 30, 2021 associated with a change in estimate of the Company’s prior year net operating loss that is able to be carried back as part of the CARES Act. The change in the provision for (benefit from) income taxes was also impacted by changes in the jurisdictional mix of earnings period over period.

The (benefit from) provision for income taxes for the three and nine months ended September 30, ~~2021~~2022 and ~~2020~~2021 differed from the federal statutory rate primarily due to the geographical mix of earnings and related foreign tax rate differential, permanent differences, research and development ~~tax~~ credits, foreign tax credits, the valuation allowance maintained against ~~certain~~the Company's deferred tax assets and withholding taxes.

The Company disaggregates its revenue by product and service in the condensed consolidated statements of operations and comprehensive (loss) income. Performance obligations related to product revenue are recognized at a point in time, while performance obligations related to service revenue are recognized over time. The Company also disaggregates its revenue based on geographic locations of its customers, as determined by the customer’s shipping address, summarized as follows:

The Company also disaggregates its revenue based on product line summarized as follows:

As of September 30, 2021 and December 31, 2020, the Company had short-term capitalized contract costs of $96 and $95, respectively, which are included in prepaid expenses and other current assets and had long-term capitalized contract costs of $67 and $70, respectively, which are included in other assets in the accompanying condensed consolidated balance sheets. During the three months ended September 30, 2021 and 2020, amortization expense associated with capitalized contract costs was $23 and $76, respectively,and during the nine months ended September 30, 2021 and 2020 was $75 and $524, respectively, all of which was recorded to selling, general and administrative expenses in the accompanying condensed consolidated statements of operations and comprehensive (loss) income.

Contract liabilities consist of deferred revenue and include payments received in advance of performance under the contract. Such amounts are recognized as revenue when the Company satisfies its performance obligations, consistent with the

above methodology. ~~For~~During the three and nine months ended September 30, 2022, the Company recognized $3,139 and $11,630, respectively,of revenue that was included in deferred revenue in the condensed consolidated balance sheet as of December 31, 2021.

~~Other Revenue Recognition Policies~~

The Company’s customary payment terms are generally 90 days or less. If the Company provides extended payment terms that represent a significant financing component, the Company adjusts the amount of promised consideration for the time value of money using an appropriate discount rate and recognizes interest income separate from the revenue recognized on contracts with customers. During the three months ended September 30, 2021 and 2020, the Company recorded interest income of $6 and $10,14.

~~15. Segment Information~~

The Company operates as 1one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the Company’s chief operating decision maker, or decision-making group, in deciding how to allocate resources and assess performance. The Company has determined that its chief operating decision maker is its President and Chief Executive Officer. The Company’s chief operating decision maker reviews the Company’s financial information on a consolidated basis for purposes of allocating resources and assessing financial performance.

The Company has, in the ordinary course of business, agreed to defend and indemnify certain customers against third-party claims asserting (i) infringement of certain intellectual property rights, which may include patents, copyrights, trademarks or trade secrets, and (ii) certain other harms caused by the acts or omissions of the Company.

As permitted under Delaware law, the Company indemnifies its officers, directors and employees for certain events or occurrences that happen by reason of their relationship with or position held at the Company.

As of September 30, ~~2021 and~~2022, the Company accrued $230 as a minimum estimated liability related to an ongoing indemnification claim. As of December 31, ~~2020,~~2021, the Company had not experienced any material losses related to these indemnification ~~obligations~~obligations. As of September 30, 2022 and 0December 31, 2021, no additional material claims were outstanding where a contingent loss was considered to be probable or reasonably estimable. The Company does not expect additional significant claims related to these indemnification obligations and, consequently, concluded that the fair value of ~~these~~any additional obligations is ~~negligible, and no related liabilities were recorded in its condensed consolidated financial statements.~~negligible.

The complete response to this section regarding legal proceedings is incorporated by reference herein to Part II Item I in this 10-Q.

As described in Note 6, "Accrued Expenses and Other Current Liabilities", the Company provides industry-standard product warranties to its customers, and is thus inherently subject to loss contingencies that include warranty claims which may arise in the ordinary course of business.

On July 21, 2022, the Company received written notification from a significant customer of one of its international subsidiaries, of alleged costs incurred and expected to be incurred by that customer with respect to an ongoing warranty matter relating to field replacements of failed units for one particular product, which failure was attributable to an unauthorized part substitution in 2019 by a supplier to the subsidiary.

Although the customer has not initiated any legal proceeding against the subsidiary or the Company to date, the customer has communicated its estimated costs for which it is seeking reimbursement. This communication was in the form of a suggested amicable settlement in the amount of approximately $31,000 for alleged costs incurred to date, plus approximately $25,000 for estimated future costs, which may be incurred over the next 5 years for a total cash settlement proposal of approximately $56,000. In addition, the settlement proposal also includes various non-monetary concessions, some of which, if agreed to, could result in significant additional costs to the Company.

Management has entered into negotiations with the customer while concurrently evaluating the settlement proposal relative to the subsidiary’s contractual warranty obligations to the customer, as well as all details of the proposed settlement, including evaluating the basis of estimated costs incurred and to be incurred and all other relevant matters regarding this settlement proposal, including contractual terms in place with this customer regarding rights, remedies, limitations of liability,

and other potential mitigating factors. The Company is also evaluating contractual obligations, responsibilities, and liabilities of the subsidiary’s part supplier in this matter.

Based on the ongoing settlement negotiations to date, as of September 30, 2022, Management has concluded that the likelihood of an unfavorable outcome is probable, and thus the Company established a reserve for the estimated expected loss in the amount of 20,000 Australian dollars, or $12,907 USD based on the exchange rate of USD $0.645 per AUD $1.00 on September 30, 2022, based on the status of ongoing negotiations. If our settlement offer were to be accepted, consideration is expected to be paid in future annual installments over 5 years.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion of our financial condition and results of operations should be read together with our condensed consolidated financial statements and related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Quarterly Report on Form 10-Q, particularly in the section titled “Risk Factors.” For discussion comparing the ~~period~~periods ended September 30, ~~2020~~2021 and September 30, ~~2019,~~2020, please refer to our Quarterly Report on ~~form~~Form 10-Q filed with the SEC on ~~October 29, 2020.~~November 2, 2021.

We offer scalable solutions that can meet the evolving bandwidth needs of our customers and their subscribers. Our first installation in a service provider’s network frequently involves deploying our broadband products in only a portion of the provider’s network and, for our cable products, with only a fraction of the capacity of our products enabled at the time of initial installation. Over time, our customers have generally expanded the use of our solutions to other areas of their networks to extend network coverage or increase network capacity.

Our solutions are commercially deployed in over 70 countries by more than 475 customers, including regional service providers as well as some of the world’s largest Tier 1 CSPs, serving millions of subscribers.

Global and Macroeconomic Considerations

COVID-19 Pandemic

The ongoing COVID-19 pandemic presents various risks to us, ~~not all of which we are able to fully evaluate or even to foresee at the current time, and~~ which could continue to have a material effect upon the estimates and judgments relied upon by management in preparing these condensed consolidated financial statements. While we remain fully operational, during the three and nine months ended September 30, ~~2021,~~2022, the effects of the COVID-19 pandemic on the global supply chain had a significant adverse effect on our financial results. In particular, certain of our products utilize components ~~for which there has been increased~~whose availability was significantly exceeded by global demand. As a result, ~~throughout 2021, and increasingly~~ during the three months ended September 30, ~~2021,~~2022, we ~~began~~continued to see shortages of supply that resulted in our inability to fulfill certain customer orders within normal lead times. This adversely impacted our revenue and operating results for the three and nine months ended September 30, ~~2021.~~2022. Additionally, shipping bottlenecks and delays further negatively affected our ability to timely fulfill customer orders, thereby delaying our ability to consummate sales and recognize revenue. We have also seen, in some cases, significant increases in shipping costs. While we continue to work with our supply chain, contract manufacturers, logistics partners and customers to minimize the extent of such impacts, we expect the effects of global supply chain issues to continue and cannot predict if or when such effects will subside. This may prevent us from being able to fulfill our customers’ orders in a timely manner or at all, which could lead to one or more of our customers cancelling their orders. At this time, we are neither able to estimate the extent of these impacts nor predict whether our efforts to minimize or contain them will be successful. We intend to continue to monitor our business very closely for any effects of COVID-19 for as long as necessary.

In addition to the negative impact on our business from global supply chain constraints related to COVID-19, we saw certain benefits that included decreases in certain operating expenses, such as travel and trade show expense, and benefited from certain U.S. government tax relief measures, discussed further below, during the year ended December 31, 2020, and the three and nine months ended September 30, 2021. We expect these benefits to gradually diminish as the various geographies in which we operate begin to recover from the pandemic.

For the nine months ended September 30, 2021, we were able to benefit from the CARES Act that was signed into law on March 27, 2020. The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer’s Social Security payments, net operating loss utilization and carryback periods, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property (QIP). For the nine months ended September 30, 2021, we recognized a reduction to cost of goods sold of $0.6 million and a

reduction in operating expenses of $4.3 million in connection with a payroll tax credit under the CARES Act. ~~For the nine months ended September 30, 2021 and 2020, we recognized an income tax benefit of $7.1 million and $9.3 million, respectively (see Note 9 to our accompanying financial statements).~~ We will continue to evaluate the impact of the CARES Act on our financial position, results of operations, and cash flows.

Rising Inflation and Interest Rates

Supply chain disruption and other economic conditions have led to a recent rise in inflation, which has caused increases in the costs to produce our products, much of which we were not immediately able to pass on to our customers due to fixed price agreements. Increased inflation may result in decreased demand for our products and services, increased operating costs

(including our labor costs), reduced liquidity and limitations on our ability to access credit or otherwise raise debt and equity capital. In addition, the U.S. Federal Reserve has raised, and may again raise interest rates in response to concerns about inflation. Increases in interest rates, especially if coupled with reduced government spending and volatility in financial markets, may have the effect of further increasing economic uncertainty and heightening these risks. In an inflationary environment, due to our fixed price agreements, we may be unable to raise the prices of our products and services commensurate with or above the rate at which our costs increase. We also may experience lower than expected sales and potential adverse impacts on our competitive position if there is a decrease in consumer spending or a negative reaction to our pricing for new customers.

In addition, because our outstanding debt bears interest at variable interest rates, the recent increases in interest rates will result in increased future debt service costs. Continued increases in interest rates will further increase the cost of servicing our outstanding indebtedness and may make refinancing our outstanding indebtedness not economically viable.

At this time, we are neither able to estimate the extent of these impacts nor predict whether our efforts to minimize or contain them will be successful. We intend to continue to monitor our business very closely for any effects of COVID-19, inflation and interest rates for as long as necessary.

Due to the above circumstances and as described generally in this Quarterly Report on Form 10-Q, our results of operations for the three and nine months ended September 30, ~~2021~~2022 are not necessarily indicative of the results to be expected in future periods. Management cannot predict the full impact of the ongoing COVID-19 pandemic on our sales channels, supply chain, manufacturing and distribution, or on economic conditions generally, including the effects on our current and potential customers, who may temporarily accelerate or curtail spending on investments in current and/or new technologies, delay new equipment evaluations and trials ~~cancel orders,~~ and possibly delay payments based on liquidity concerns, all of which could have a material impact on our business in the future. Similarly, our supply chain and our contract manufacturers could continue to be affected, which could cause further disruptions to our ability to meet customer demand or delivery ~~schedules.~~schedules and continued cost increases. For the three and nine months ended September 30, ~~2021,~~2022, we ~~did see~~experienced certain delays in our supply chain that adversely impacted delivery schedules to our ~~customers.~~customers and cost increases that adversely impacted our gross margins. If COVID-19 were to have such effects in the future, there would likely be afurther material adverse ~~impact~~impacts on our financial results, liquidity and capital resource needs. This uncertainty makes it challenging for management to estimate the future performance of our business, particularly in the near to medium ~~term and the~~term. The impact of COVID-19, rising inflation, increased interest rates and general economic uncertainty could have a material adverse impact on our results of operations in the near to medium term.

Product revenues during the three months ended September 30, ~~2021~~2022 were adversely affected by supply chain delays across all of our markets. Wireless and cable revenues ~~increased despite such delays,~~also decreased significantly due to ~~increased revenues~~decreased orders from certain Tier 1 customers in the period, ~~including increased sales~~as well as timing of certain ~~end of life products that are not expected to derive significant~~orders.

Service revenues in future periods. In addition to the impact of supply chain delays, our fixed telco revenue declined due to decreased revenues from one Tier 1 customer, whose planned network buildout is nearing its completion. The decline in cable revenue was primarily the result of the aforementioned supply chain delays.remained relatively consistent period over period.

~~The decrease in service revenue was primarily due to decreased sales of services in the three months ended September 30, 2021 as compared to the three months ended September 30, 2020.~~

The ~~increase~~decrease in cost of product revenue and the decrease in product gross margin ~~was~~were due to product mix, with a lower proportion of higher margin software ~~products and increased lower margin wireless customer premise equipment~~ product ~~sales.~~revenue in the three months ended September 30, 2022 as compared to the three months ended September 30, 2021.

Cost of service revenue and service gross margin remained relatively consistent period over period.

The decrease in gross margin was further driven by a warranty settlement provision of $12.9 million recorded during the three months ended September 30, 2022, which reduced the margin by 19.3%.

The increase in product revenue was primarily attributable to continued increased demand for our wireless products. The increase in wireless revenue was partially offset by decreased revenue from our fixed telco products, which is due to decreased demand from a Tier 1 customer that is completing its network buildout, and decreased revenue from our cable products, which have been adversely affected by supply chain delays.

The overall increase in service revenue was primarily due to increased support renewals and sales of services in cable and fixed telco, which was partially offset by a decline in wireless service revenue that was due to an increase in sales of certain wireless customer premise equipment products, for which we do not sell service contracts.

2021. The decrease in ~~research and development expense~~gross margin was ~~mainly~~also due to ~~a $1.6~~an increase in inventory reserves of $2.4 million period over period.

Cost of service revenue and service gross margin remained relatively consistent period over period.

The decrease in ~~purchases~~gross margin was further driven by a warranty settlement provision of ~~research and development materials. This decrease was partially offset by increased personnel costs of $0.7~~$12.9 million ~~caused primarily by increased salaries and benefits of $3.3 million~~recorded during the nine months ended September 30, ~~2021~~2022, which reduced the margin by 6.4%. Please refer to Note 16 "Commitments and Contingencies" of the accompanying condensed consolidated financial statements for more discussion regarding this provision.

The ~~decrease~~increase in selling, general and administrative expense was primarily due to an increase in personnel costs of $0.9 million, driven by the impact of a decrease of $1.2 million in professional services and a $1.9 million decrease in depreciation expense as assets that became fully depreciated were not replaced.

The change in the provision for income taxes for the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021 was impacted by a discrete benefit of $7.1 million recorded ~~during~~in the nine months ended September 30, 2021 related to loss carrybacks associated with ~~a change in estimate of our prior year taxable net operating loss that is able to be carried back as part of~~ the CARES Act. The change in the ~~(benefit from)~~provision for income taxes was also impacted by the new requirement to capitalize and amortize all research and experimentation expenditures for U.S. tax purposes, which became effective under the Tax Cuts and Jobs Act (“TCJA”) as of January 1, 2022. This new requirement resulted in significant forecasted U.S. current income tax for the 2022 year and the corresponding deferred tax asset created is offset by a full valuation allowance. The change in the provision for income taxes was also impacted by changes in the jurisdictional mix of earnings ~~period over period.~~and the valuation allowance maintained against our deferred tax assets.

Liquidity and Capital Resources

Our principal sources of liquidity have been and continue to be our cash and cash equivalents and cash flows from operations.

We maintain a $25.0 million revolving credit facility, under which we have drawn $6.5 million and utilized $1.5 million of available credit, which we used as collateral for two stand-by letters of credit, leaving $17.0 million of available credit as of September 30, 2021.

Cash Flows

Operating Activities

Our primary source of cash from operating activities has been cash collections from our customers. We expect cash flows from operating activities to be affected by ~~increases and decreases~~changes in sales volumes and timing of collections, and by purchases and shipments of inventory. Our primary uses of cash from operating activities have been for personnel costs and investment in our selling, general and administrative departments and research and development. Future cash outflows from operating activities may increase as a result of further investment in research and development and selling, general and administrative requirements, ~~and~~as well as increases in personnel costs as we continue to grow our business by enhancing our existing products and introducing new products.

During the nine months ended September 30, ~~2021~~,2022, cash provided by operating activities was ~~$15.2~~$11.7 million, primarily resulting from ~~our net income of $1.7 million, net non-cash adjustments of $21.9 million and~~ net cash ~~used~~provided by changes in our operating assets and liabilities of ~~$8.4~~$68.9 million and net non-cash adjustments of $23.2 million, partially offset by our net loss of $80.4 million. ~~The net~~Net cash ~~used~~provided by changes in our operating assets and liabilities during the nine months ended September 30, ~~2021~~2022 was primarily due to a $17.6 million decrease in accounts payable due to timing of vendor payments; a $6.1 million decrease in accrued expenses; a $5.9 million increase in prepaid income taxes; a $1.6 million increase in prepaid expenses and other assets; and a $1.6 million decrease in accrued income taxes. These uses were partially offset by a $13.2$35.6 million decrease in accounts receivable due to collections during the period; a ~~$9.3~~$21.0 million ~~net~~ decrease in ~~inventory; and~~prepaid income taxes; a ~~$1.9~~$18.0 million increase in deferred revenue due to the timing of revenue ~~recognition.~~recognition; a $7.5 million increase in accrued expenses due to the timing of certain accrual payments; a $2.1 million increase in accrued income taxes; and a $1.8 million decrease in prepaid expenses. These sources of cash were partially offset by a $13.6 million decrease in accounts payable due to timing of vendor payments; and a $3.4 million increase in inventory.

Investing Activities

Our investing activities have consisted primarily of expenditures for lab and computer equipment and software to support the development of new products. In addition, our investing activities ~~include~~included expansion of and improvements to our facilities. AsTo the extent our business expands, we expect that we will continue to invest in these areas.

Net cash used in investing activities during the nine months ended September 30, ~~2021~~2022 was ~~$4.4~~$3.3 million, consisting of purchases of property and equipment and software licenses.

Financing Activities

Net cash ~~used in~~provided by financing activities during the nine months ended September 30, ~~2021~~2022 was ~~$11.9~~$34.2 million, ~~consisting primarily~~which was mainly due to the $39.5 million received from the Securities Purchase Agreement, or SPA, with Verizon Ventures LLC on April 18, 2022, net of ~~debt principal repayments~~issuance costs of ~~$9.0~~$0.1 million, ~~and~~combined with proceeds from the exercises of stock options of $0.3 million. These amounts were partially offset by employee taxes paid related to net share settlement of equity awards of ~~$6.3~~$2.1 million, primarily due to ~~PSUs~~certain RSUs that vested during the nine months ended September 30, ~~2021. These payments were partially offset by proceeds from the exercise~~2022; repurchases of ~~stock options of $3.5 million.~~

~~Commercial Mortgage Loan~~

In July 2015, we entered into an $8.0 million commercial mortgage loan agreement, which matured on July 1, 2020. On July 1, 2020, we paid in full the remaining $6.5 million in unpaid principal and accrued interest under the mortgage loan with funds drawn upon our revolving credit facility. The annual interest rate on the loan was 3.5%, and the loan was repayable in 60 monthly installments of principal and interest based on a 20-year amortization schedule.

~~Term Loan and Revolving Credit Facilities~~

On December 20, 2016, we entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, various lenders and JPMorgan Chase Bank, N.A. and Barclays Bank PLC, as joint lead arrangers and joint bookrunners, providing for:

•

~~a term loan facility of $300.0 million; and~~

•

~~a revolving credit facility of up to $25.0 million in revolving credit loans and letters of credit.~~

As of September 30, 2021 and December 31, 2020, we had borrowings of $279.0 million and $288.0 million, respectively, outstanding under the term loan facility. As of September 30, 2021 and December 31, 2020 we had borrowings of $6.5 million under the revolving credit facility, which were drawn down to fund the repayment of our commercial mortgage loan. However, on October 25, 2021, we repaid the full balance of outstanding borrowings under the revolving credit facility with cash and cash equivalents in the condensed consolidated balance sheets as of September 30, 2021. As of September 30, 2021 and December 31, 2020, we had also used $1.5 million of available credit under the revolving credit facility for two stand-by letters of credit, one which serves as collateral to one of our customers pursuant to a contractual obligation and one which is used as collateral for operating leases in Australia. In addition, we may, subject to certain conditions, including the consent of the administrative agent and the institutions providing such increases, increase the facilities by an unlimited amount so long as we are in compliance with specified leverage ratios, or otherwise by up to $70.0 million.

Borrowings under the facilities bear interest at a floating rate, which can be either a Eurodollar rate plus an applicable margin or, at our option, a base rate (defined as the highest of (x) the JPMorgan Chase, N.A. prime rate, (y) the federal funds effective rate, plus one-half percent (0.50%) per annum and (z) a one-month Eurodollar rate plus 1.00% per annum) plus an applicable margin. The applicable margin for borrowings under the term loan facility is 4.00% per annum for Eurodollar rate loans (subject to a 1.00% per annum interest rate floor) and 3.00% per annum for base rate loans. The applicable margin for borrowings under the revolving credit facility is 1.75% per annum for Eurodollar rate loans and 0.75% per annum for base rate loans, subject to reduction based on our maintaining specified net leverage ratios. The interest rates payable under the facilities are subject to an increase of 2.00% per annum during the continuance of any payment default.

For Eurodollar rate loans, we may select interest periods of one, three or six months or, with the consent of all relevant affected lenders, twelve months. Interest will be payable at the end of the selected interest period, but no less frequently than every three months within the selected interest period. Interest on any base rate loan is not set for any specified period and is payable quarterly. We have the right to convert Eurodollar rate loans into base rate loans and the right to convert base rate loans into Eurodollar rate loans at our option, subject, in the case of Eurodollar rate loans, to breakage costs if the conversion is effected prior to the end of the applicable interest period. As of September 30, 2021 and December 31, 2020, the interest rate on the term loans was 5.00% per annum, which was based on a three-month and six-month Eurodollar rate, respectively, at the applicable floor of 1.00% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans. As of September 30, 2021, the interest rate on the revolving credit facility was 1.83% per annum, which was based on a one-month Eurodollar rate of 0.08% per annum plus the applicable margin of 1.75% per annum for Eurodollar rate loans. As of December 31, 2020, the interest rate on the revolving credit facility was 2.12% per annum, which was based on the six-month Eurodollar rate of 0.37% per annum plus the applicable margin of 1.75% per annum for Eurodollar rate loans.

The revolving credit facility also requires payment of quarterly commitment fees at a rate of 0.25% per annum on the difference between committed amounts and amounts actually borrowed under the facility and customary letter of credit fees.

The term loan matures on December 20, 2023 and the revolving credit facility matures on December 20, 2021. The term loan facility is subject to amortization in equal quarterly installments, which commenced on March 31, 2017, of principal in an annual aggregate amount equal to 1.0% of the original principal amount of the term loans of $300.0 million, with the remaining outstanding balance payable at the date of maturity.

Voluntary prepayments of principal amounts outstanding under the term loan facility are permitted at any time; however, if a prepayment of principal is made with respect to a Eurodollar loan on a date other than the last day of the applicable interest period, we are required to compensate the lenders for any funding losses and expenses incurred as a result of the prepayment. Prior to the revolving credit facility maturity date, funds borrowed under the revolving credit facility may be borrowed, repaid and reborrowed, without premium or penalty.

In addition, we are required to make mandatory prepayments under the facilities with respect to (i) 100% of the net cash proceeds from certain asset dispositions (including casualty and condemnation events) by us or certain of our subsidiaries, subject to certain exceptions and reinvestment provisions, (ii) 100% of the net cash proceeds from the issuance or incurrence of any additional debt by us or certain of our subsidiaries, subject to certain exceptions, and (iii) 50% of our excess cash flow, as defined in the credit agreement, subject to reduction upon our achievement of specified performance targets. In accordance with these provisions, a mandatory prepayment of $6.8 million was paid on April 2, 2021.

The facilities are secured by, among other things, a first priority security interest, subject to permitted liens, in substantially all of our assets and all of the assets of certain of our subsidiaries and a pledge of certain of thetreasury stock of ~~certain~~$1.2 million; and debt principal repayments of our subsidiaries, in each case subject to specified exceptions. The facilities contain customary affirmative and negative covenants, including certain restrictions on our ability to pay dividends, and, with respect only to the revolving credit facility, a financial covenant requiring us to maintain a specified total net leverage ratio, in the event that on the last day of any fiscal quarter, we have utilized more than 30% of our borrowing capacity under the revolving credit facility (subject to certain exceptions). The term loan facility contains a cross-default provision, whereby, if repayment of borrowings under the revolving credit facility are accelerated due to a default of the net leverage ratio covenant, repayment of the outstanding term loan balance could also be accelerated. Because the financial covenant under the revolving credit facility only applies if outstanding utilization thereunder exceeds 30% of the total borrowing capacity on the last day of each fiscal quarter, this cross-default provision has the effect of limiting our ability to utilize more than 30% of our total borrowing capacity under the revolving credit facility of $25.0 million if both our net leverage ratio exceeds the maximum permitted by the agreement and we would not otherwise be able to reduce our outstanding utilization of the revolving credit facility to below the 30% testing threshold prior to the last day of any quarter. As of September 30, 2021 and December 31, 2020, we were in compliance with all applicable covenants of the facilities. We do not expect to require the use of the revolving credit facility to fund operations during the next 12 months.$2.3 million.

~~Tax Cuts and Jobs Act~~35

Of our total cash and cash equivalents of $156.5 million as of September 30, 2021, $143.6 million was held by our foreign subsidiaries. The Tax Cuts and Jobs Act, or TCJA, established a modified territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. As of September 30, 2021, we had $25.5 million of undistributed earnings in China that are not indefinitely reinvested. The remaining unremitted earnings of our foreign subsidiaries are either indefinitely reinvested or could be remitted with an immaterial tax cost.Cash Flows from Future Operations

We believe our existing cash and cash equivalents and anticipated cash flows from future operations ~~and liquidity available from our revolving credit facility~~ will be sufficient to meet our working capital and capital expenditure needs and debt service obligations for at least the next 12 months. As described in Note 9 within our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, our outstanding Term Loan is scheduled to mature in December 2023, and we have commenced the refinancing process. If we are unable to successfully complete a refinancing of a sufficient portion of the outstanding balance prior to maturity or otherwise satisfy our repayment obligations, there may be substantial doubt about our ability to continue as a going concern beyond the maturity date of the loan.

Our future capital requirements may vary materially from those currently planned and will depend on many factors, including our rate of revenue growth, the timing and extent of spending on research and development efforts and other business initiatives, purchases of capital equipment to support our growth, the expansion of sales and marketing activities, expansion of our business through acquisitions or our investments in complementary products, technologies or businesses, the use of working capital to purchase additional inventory, the timing of new product introductions, market acceptance of our products and overall economic conditions. To the extent that current and anticipated future sources of liquidity are insufficient to fund our future business activities and requirements, we may be required to seek additional equity or debt financing. In the event additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all.

Term Loan and Revolving Credit Facilities

•

a term loan facility, or the Term Loan, of $300.0 million; and

•

a revolving credit facility of up to $25.0 million in revolving credit loans and letters of credit.

As of September 30, 2022 and December 31, 2021, we had borrowings of $276.0 million and $278.2 million, respectively, outstanding under the Term Loan. On December 20, 2021, the revolving credit facility matured.

Borrowings under the Term Loan bear interest at a floating rate, which can be either a Eurodollar rate plus an applicable margin or, at our option, a base rate (defined as the highest of (x) the JPMorgan Chase, N.A. prime rate, (y) the federal funds effective rate, plus one-half percent (0.50%) per annum and (z) a one-month Eurodollar rate plus 1.00% per annum) plus an applicable margin. The applicable margin for borrowings under the Term Loan is 4.00% per annum for Eurodollar rate loans (subject to a 1.00% per annum interest rate floor) and 3.00% per annum for base rate loans. The interest rates payable under the Term Loan are subject to an increase of 2.00% per annum during the continuance of any payment default.

For Eurodollar rate loans, we may select interest periods of one, three or six months or, with the consent of all relevant affected lenders, twelve months. Interest will be payable at the end of the selected interest period, but no less frequently than every three months within the selected interest period. Interest on any base rate loan is not set for any specified period and is payable quarterly. We have the right to convert Eurodollar rate loans into base rate loans and the right to convert base rate loans into Eurodollar rate loans at our option, subject, in the case of Eurodollar rate loans, to breakage costs if the conversion is effected prior to the end of the applicable interest period. As of September 30, 2022, the interest rate on the Term Loan was 7.12% per annum, which was based on a one-month Eurodollar rate of 3.12% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans. As of December 31, 2021, the interest rate on the Term Loan was 5.00% per annum, which was based on a one-month Eurodollar rate, at the applicable floor of 1.00% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans.

The Term Loan matures on December 20, 2023 and is subject to amortization in equal quarterly installments, which commenced on March 31, 2017, of principal in an annual aggregate amount equal to 1.0% of the original principal amount of the term loans of $300.0 million, with the remaining outstanding balance payable at the date of maturity.

Voluntary prepayments of principal amounts outstanding under the Term Loan are permitted at any time; however, if a prepayment of principal is made with respect to a Eurodollar loan on a date other than the last day of the applicable interest period, we are required to compensate the lenders for any funding losses and expenses incurred as a result of the prepayment.

In addition, we are required to make mandatory prepayments under the Term Loan with respect to (i) 100% of the net cash proceeds from certain asset dispositions (including casualty and condemnation events) by us or certain of our subsidiaries, subject to certain exceptions and reinvestment provisions, (ii) 100% of the net cash proceeds from the issuance or incurrence of any additional debt by us or certain of our subsidiaries, subject to certain exceptions, and (iii) 50% of our excess cash flow, as defined in the credit agreement, subject to reduction upon our achievement of specified performance targets.

The Term Loan is secured by, among other things, a first priority security interest, subject to permitted liens, in substantially all of our assets and all of the assets of certain of our subsidiaries and a pledge of certain of the stock of certain of our subsidiaries, in each case subject to specified exceptions. The Term Loan contains customary affirmative and negative covenants, including certain restrictions which are currently in effect based upon our total net leverage ratio, such as our ability to pay dividends and repurchase outstanding shares. As of September 30, 2022 and December 31, 2021, we were in compliance with all applicable covenants of the Term Loan.

Tax Cuts and Jobs Act

Of our total cash and cash equivalents of $196.6 million as of September 30, 2022, $101.0 million was held by our foreign subsidiaries. The TCJA established a modified territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. As of September 30, 2022, we had $28.1 million of undistributed earnings in China that were not indefinitely reinvested. The remaining unremitted earnings of our foreign subsidiaries are either indefinitely reinvested or could be remitted with an immaterial tax cost.

The TCJA included a provision requiring companies to capitalize all of their research and development costs incurred in tax years beginning after 2021. As a result, research and development costs can no longer be expensed as incurred for tax purposes, and must be capitalized and amortized, 5 years for domestic research and 15 years for international. While it is possible that Congress may retroactively defer, modify or repeal this provision, any such actions would be accounted for in the period of enactment. Absent such Congressional action, this change in tax law will result in significant cash tax payments and have a material adverse effect on our liquidity.

Securities Purchase Agreement with Verizon Ventures LLC

On April 18, 2022, we entered into a Stock Purchase Agreement, or SPA, with Verizon Ventures LLC providing for the private placement of an aggregate of 9.3 million shares of our common stock, par value $0.001 per share, at a price of $4.24 per share, for an aggregate purchase price of approximately $39.5 million.

We filed a resale registration statement with the SEC on May 17, 2022, and intend to use the net proceeds from the private placement for general corporate purposes.

Stock Repurchase Program

On February 21, 2019, we announced a stock repurchase program under which we were authorized to repurchase up to $75.0 million of our common stock. During the nine months ended September 30, ~~2020,~~2022, we repurchased approximately ~~1.2~~0.2 million shares for a total cost of approximately ~~$3.0~~$1.2 million. During the nine months ended September 30, 2021 we did not repurchase any shares. As of September 30, ~~2021,~~2022, approximately ~~$70.2~~$60.2 million remained authorized for repurchases of our common stock under the stock repurchase program. However, based on our net leverage ratio at September 30, 2022, as described in Note 9 of the above notes to our condensed consolidated financial statements, our ability to repurchase shares is currently restricted. The stock repurchase program has no expiration date and does not require us to purchase a minimum number of shares, and we may suspend, modify or discontinue the stock repurchase program at any time without prior notice.

Contractual Obligations, Commitments and ~~Commitments~~Contingencies

Our material contractual obligations include our term loan, ~~facility, revolving credit facility,~~ operating leases and purchase agreements with our contract manufacturers and suppliers. ~~There~~Other than the addition of a warranty settlement provision during the three months ended September 30, 2022, as discussed above and in the notes to the accompanying condensed consolidated financial statements, there have been no material changes to our contractual obligations, commitments and ~~commitments~~contingencies from those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2020.~~2021.

Critical Accounting Policies and Significant Judgments and Estimates

We prepare our condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States. The preparation of condensed consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related

disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by our management.

Other than ~~our policies related to stock-based compensation and~~ our adoption of ASU ~~2020-06,~~2021-08, as described in Note 2 ~~of the above notes to the~~within our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, there have been no material changes to our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2020.~~2021.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market risk is the risk of loss to future earnings, values or future cash flows that may result from changes in the price of a financial instrument. The value of a financial instrument may change as a result of changes in interest rates, exchange rates, commodity prices, equity prices and other market changes. We are exposed to market risk related to changes in foreign currency exchange rates and interest rates. We currently mitigate certain foreign currency exchange rate risks with derivative instruments and enter into exchange rate hedging arrangements to manage certain of the risks described below. We do not engage in foreign currency speculation.

~~Foreign Currency Exchange Risk~~

We have accounts receivables denominated in foreign currencies, and our operations outside of the United States incur their operating expenses in foreign currencies. To date, the majority of our product sales and inventory purchases have been denominated in U.S. dollars. For our subsidiaries in Ireland and Australia, the U.S. dollar is the functional currency. For each of our other foreign subsidiaries, the functional currency is the local currency. During the nine months ended September 30, 2021 and 2020, we incurred foreign currency transaction (losses) gains of $(1.4) million and $0.7 million, respectively, primarily related to unrealized and realized foreign currency (losses) gains for accounts receivable denominated in foreign currencies and operating expenses that are denominated in local currencies. We recorded these foreign currency transaction (losses) gains as a component of other income (expense), net in our condensed consolidated statements of operations and comprehensive (loss) income. We believe that a 10% change in the exchange rate between either the U.S. dollar and Euro or the U.S. dollar and Australian dollar would not materially impact our operating results or financial position.

Our foreign currency risk management practices are principally intended to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currencies resulting from changes in foreign currency exchange rates. From time to time we enter into cash flow hedges, which utilize foreign currency forward contracts to hedge specific forecasted transactions of our foreign subsidiaries with the goal of protecting our budgeted revenues and expenses against foreign currency exchange rate changes compared to our budgeted rates. During the three and nine months ended September 30, 2020, we settled two cash flow hedges which were used to hedge specific operating cash flows denominated in Australian dollars. No cash flow hedges were settled or outstanding during the three or nine months ended September 30, 2021.

Additionally, from time to time, we enter into other foreign currency forward contracts with the goal of protecting outstanding receivables denominated in currencies other than the U.S. dollar. As of September 30, 2021 we had two currency forward contracts outstanding with notional amounts totaling 1.4 million Euros that will mature in the fourth quarter of 2021 and first quarter of 2022 and we expect to continue to hedge certain significant transactions denominated in currencies other than the U.S. dollar in the future.

The success of our foreign currency risk management program depends upon forecasts of transaction activity denominated in various currencies. To the extent that these forecasts are overstated or understated during periods of currency volatility, we could experience unanticipated foreign currency gains or losses that could have a material impact on our results of operations. Furthermore, our failure to identify new exposures and hedge against them in an effective manner may result in material foreign currency gains or losses.

Interest Rate Sensitivity

Our cash and cash equivalents as of September 30, 2021 and December 31, 2020 consisted of cash maintained in FDIC-insured operating accounts as well as investments in money market mutual funds and certificates of deposit. We also

have policies requiring that we invest in high-quality issuers, limit our exposure to any individual issuer, and ensure adequate liquidity. Our primary exposure to market risk for our cash equivalents is interest income sensitivity, which is primarily affected by changes in the general level of U.S. interest rates. However, we do not believe a sudden change in the interest rates for our cash equivalents would have a material impact on our financial condition, results of operations or cash flows.

WeAs described above, we have a credit agreement that provides us with a ~~term loan facility~~Term Loan of $300.0 ~~million and a revolving credit facility of up to $25.0 million in revolving credit loans and letters of credit.~~million. Borrowings under the ~~facilities~~Term Loan bear interest at a floating rate, which can be either a Eurodollar rate plus an applicable margin or, at our option, a base rate (defined as the highest of (x) the JPMorgan Chase, N.A. prime rate, (y) the federal funds effective rate, plus one-half percent (0.50%) per annum and (z) a one-month Eurodollar rate plus 1.00% per annum) plus an applicable margin. The applicable margin for borrowings under the ~~term loan facility~~Term Loan is 4.00% per annum for Eurodollar rate loans (subject to a 1.00% per annum interest rate floor) and 3.00% per annum for base rate loans. ~~The applicable margin for borrowings under~~

As a result of the ~~revolving credit facility is 1.75% per annum for Eurodollar~~interest rate ~~loans~~floor and ~~0.75% per annum for base~~our election to select longer interest rate ~~loans, subject to reduction based on our maintaining of specified net leverage ratios.~~

~~As of~~periods, also as described above, through September 30, ~~2021,~~2022, we ~~had borrowings of $279.0 million outstanding under the term loan facility, bearing~~have not been materially impacted by recent interest ~~at a~~ rate ~~of 5.00% per annum, which was based on a three-month Eurodollar rate at the applicable floor of 1.00% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans. Changes in~~increases. However, we will incur increased interest ~~rates could cause interest charges on our term loan facility~~expenses subsequent to ~~fluctuate.~~September 30, 2022. Based on the amount of borrowings outstanding as of September 30, ~~2021,~~2022, an increase or decrease of 10% in the Eurodollar rate would have no impact on our earnings and cash flows, as the interest rate in effect at September 30, 2021 on the term loan facility was at the applicable floor of 1.00% per annum and would continue to be in effect with a change of 10%.

~~On July 1, 2020, we drew down upon our revolving credit facility under our term loan agreement in the amount of $6.5 million. As noted in Note 10,~~ ~~Debt~~, borrowings under the revolving credit facility mature on December 21, 2021 and the applicable margin for borrowings under the revolving credit facility is 1.75% per annum for Eurodollar rate loans. The interest rate on the outstanding borrowings as of September 30, 2021 was 1.83%, which was based on a one-month Eurodollar rate of 0.08% per annum plus the applicable margin of 1.75% per annum for Eurodollar rate loans. An increase or decrease of 10% in the one-month Eurodollar rate2022 would ~~result in~~cause a pre-tax ~~change~~decrease and increase, respectively, to our earnings and cash flows of ~~less than $0.1~~approximately $0.9 million per year, assuming ~~that~~ such rate ~~was~~were to remain in effect for a year.

~~Inflation Risk~~

~~We do not believe that inflation has had a~~Other than as described above, there have been no material ~~effect~~changes to our market risks related to foreign currency exchange and interest rate sensitivity as disclosed in our Annual Report on ~~our business to date. However, as more fully described in Item 2 above, global demand~~Form 10-K for the ~~base materials utilized by our suppliers and supply chain risks could result in~~fiscal year ended December 31, 2021.

Inflation Risk

The Company has experienced a significant ~~increases~~increase in the costs of ~~the~~ components and subcontract manufacturing of our products, as well as increased operating expenses as a result of recent increases in inflation, which we ~~purchase, and we may~~were not be able to fully ~~offset such higher costs~~recover through price ~~increases. Our inability~~increases to our customers. While it is not possible to measure or ~~failure to do so~~estimate the direct impact, continued period of high inflation could ~~harm~~have a material adverse effect on our business, operating results and financial condition.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a- 15(e) and 15d- 15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act), as of the end of the period covered by this Quarterly Report on Form 10-Q. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Chief Financial Officer have concluded that as of such date, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we are a party to various litigation matters and subject to claims that arise in the ordinary course of business including, for example, patent infringement lawsuits by non-practicing entities. In addition, third parties may from time to time assert claims against us in the form of letters and other communications.

~~On May 29, 2019, John Shen filed a putative shareholder class action complaint in the Massachusetts Superior Court of Essex County,~~ ~~John Shen v. Casa Systems, Inc, et al., Civil Action No. 1977CV00787~~, against us; certain of our current and former executive officers and directors; Summit Partners, our largest investor; and the underwriters from our December 15, 2017, initial public offering, or IPO. On July 3, 2019, Mirza R. Baig filed a similar putative shareholder class action complaint in the Massachusetts Superior Court of Essex County, ~~Mirza R. Baig v. Casa Systems, Inc., Civil Action No.1977CV00961, against the same defendants. The two matters were subsequently consolidated and transferred to the Business Litigation Session of the Massachusetts Superior Court, Suffolk County,~~ ~~John Shen v. Casa Systems, Inc, et al.,Civil Action No. 19-CV-03203-BLS2~~ ~~andMirza R. Baig v. Casa Systems, Inc., Civil Action No.~~ ~~19-CV-03204-BLS2~~. The complaints, as later amended on November 12, 2019, purported to be brought on behalf of all purchasers of our common stock in and/or traceable to the IPO. The complaints generally alleged that (i) each of the defendants violated Section 11 and/or Section 12(a)(2) of the Securities Act of 1933, as amended, or the Securities Act, because documents related to the IPO, including our registration statement and prospectus were materially misleading by containing untrue statements of material fact and/or omitting to state material facts necessary to make such statements not misleading and (ii) the individual defendants and Summit Partners acted as controlling persons within the meaning and in violation of Section 15 of the Securities Act. Plaintiffs sought, among other things, compensatory damages, costs and expenses, including counsel and expert fees, rescission or a rescissory measure of damages, and equitable and injunctive relief. On January 12, 2021, the court granted motions to dismiss filed by the defendants. On February 22, 2021, plaintiffs filed notice of appeal.

~~On August 9, 2019, Donald Hook filed a putative shareholder class action lawsuit in the Supreme Court of the State of New York, County of New York,~~ ~~Donald Hook, et al., v. Casa Systems, Inc. et al., Index No. 654548/2019~~, against the same defendants named in the Shen and Baig matters. The complaint, as later amended on November 22, 2019, purports to be brought on behalf of all purchasers of our common stock in and/or traceable to our IPO and generally alleges that (i) each of the defendants violated Section 11 and/or Section 12(a)(2) of the Securities Act because documents related to our IPO including our registration statement and prospectus were materially misleading by containing untrue statements of material fact and/or omitting to state material facts necessary to make such statements not misleading and (ii) the individual defendants and Summit Partners acted as controlling persons within the meaning and in violation of Section 15 of the Securities Act. Plaintiff sought, among other things, compensatory damages, costs and expenses, including counsel and expert fees, rescission or a rescissory measure of damages, disgorgement, and equitable and injunctive relief. On August 30, 2021, the court granted motions to dismiss filed by the defendants. On September 30, 2021, plaintiff filed notice of appeal.

~~On August 13, 2019, Panther Partners, Inc. filed a putative shareholder class action lawsuit in the Supreme Court of the State of New York, New York County,~~ ~~Panther Partners, Inc., et al., v. Jerry Guo et al., Index No 654585/2019~~, against us, certain of our current and former executive officers and directors, and the underwriters from our April 30, 2018 follow-on offering of common stock, which we refer to as our “Follow-on Offering.” The complaint, as later amended on November 22, 2019, purports to be brought on behalf of all purchasers of our common stock in our Follow-on Offering and generally alleges that (i) each of the defendants, other than Abraham Pucheril, violated Section 11 of the Securities Act, and each of the defendants violated Section 12(a)(2) of the Securities Act, because documents related to our Follow-on Offering, including our registration statement and prospectus, were materially misleading by containing untrue statements of material fact and/or omitting to state material facts necessary to make such statements not misleading and (ii) the individual defendants acted as controlling persons within the meaning and in violation of Section 15 of the Securities Act. Plaintiff sought, among other things, compensatory damages, costs and expenses, including counsel and expert fees, rescission or a rescissory measure of damages, and equitable and injunctive relief. On October 4, 2021, the court granted motions to dismiss filed by the defendants.

No amounts have been accrued for any of the putative class action lawsuits referenced above as of September 30, 2021, as we do not believe the likelihood of a material loss is probable. Although the ultimate outcome of these matters cannot be predicted with certainty, the resolution of any of these matters could have a material impact on our results of operations in the period in which such matter is resolved.

Item 1A. Risk Factors.

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in “Part I, Item 1A Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2020,~~2021, or the ~~2020~~2021 10-K, which could materially affect our business, financial condition or future results. As a supplement to the risk factors identified in the 2021 10-K, below we have set forth a new risk factor (regarding inflation). Other than ~~the updated risk factors described~~as provided below, there have been no material changes from the risk factors previously disclosed in the ~~2020~~2021 10-K.

Risks Related to ~~COVID-19 Pandemic~~Our Operations

~~The coronavirus outbreak~~Rising inflation rates could negatively impact our ~~operations~~revenues and profitability if increases in the prices of our products and services or a decrease in customer spending results in lower sales. If we are not able to pass cost increases on to our customers, our gross margin and net income would be adversely affected, and the adverse impact may be material. In addition, rising inflation rates have resulted in a significant increase in interest rates, which will also have an adverse ~~effect~~impact on our ~~revenues~~financial results.

Recent significant increases in inflation rates may result in decreased demand for our products and services, increased manufacturing and operating costs (including our labor costs), reduced liquidity, and limitations on our ability to access credit or otherwise raise debt and equity capital. In an inflationary environment, because certain of our customer contracts provide for fixed pricing and/or ~~results~~due to our competitor’s pricing strategies, we may be unable to raise the sales prices of ~~operations.~~

~~The COVID-19 pandemic presents various risks to us, not all of~~our products and services at or above the rate at which ~~we are able to fully evaluate or even to foresee at the current time,~~our costs increase, which would reduce our profit and ~~which~~operating margins and could have a material effect upon the estimates and judgments relied upon by management in preparing these condensed consolidated financial statements. While we remain fully operational, during the three and nine months ended September 30, 2021, the effects of the COVID-19 pandemic on the global supply chain had a significant adverse effect on our financial results. ~~In particular, certain of~~We also may experience lower than expected sales and potential adverse impacts on our ~~products utilize components, for which~~competitive position if there ~~has been increased global demand. As~~is a ~~result, throughout 2021, and increasingly during the three months ended September 30, 2021,~~decrease in customer spending or a negative reaction to any price increases we ~~began~~are able to ~~see shortages of supply that resulted~~implement. A reduction in our ~~inability to fulfill certain customer orders within normal lead times. This adversely impacted our~~ revenue and operating results for the three and nine months ended September 30, 2021. While we continue to work with our supply chain, contract manufacturers, and customers to minimize the extent of such impacts, we expect the effects of global supply chain issues to continue and cannot predict when such effects will subside. This may prevent us from being able to fulfill our customers’ orders in a timely manner or at all, which could lead to one or more of our customers cancelling their orders. At this time, we are neither able to estimate the extent of these impacts nor predict whether our efforts to minimize or contain them willwould be ~~successful. We intend to continue to monitor our business very closely for any effects of COVID-19 for as long as necessary.~~

Due to the above circumstances and as described generally in our 2020 Annual Report on Form 10-K, our results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected in future periods. Management cannot predict the full impact of the COVID-19 pandemic on our sales channels, supply chain, manufacturing and distribution, or on economic conditions generally, including the effects on our current and potential customers, who may curtail spending on investments in current and/or new technologies, delay new equipment evaluations and trials, cancel orders, and possibly delay payments based on liquidity concerns, all of which could have a material impact on our business in the future. Similarly, our supply chain and our contract manufacturers could be affected, which could cause disruptionsdetrimental to our ~~ability to meet customer demand or delivery schedules. For the three~~profitability and ~~nine months ended September 30, 2021, we did see certain delays in our supply chain that adversely impacted delivery schedules to our customers. If COVID-19 were to~~financial condition and could also have ~~such effects in the future, there would likely be a material~~an adverse impact on our ~~financial results, liquidity~~future growth. In addition, the United States Federal Reserve has raised, and ~~capital resource needs. This uncertainty makes it challenging for management~~may continue to ~~estimate the future performance of our business, particularly~~raise, interest rates in ~~the near~~response to ~~medium term~~concerns about inflation. We have significant outstanding debt that carries interest at variable rates, and ~~the impact of COVID-19 could~~thus, increases in interest rates have a material adverse impact on our ~~results of operations in the near to medium term.~~profitability.

~~The coronavirus outbreak has resulted in an increase in demand for certain of our solutions, which may subside or decrease when the pandemic ends.~~40

The pandemic and resulting lockdowns have resulted in an increase in demand for residential broadband services, which has in turn led to an increase in demand for certain of our solutions, including our fiber extension home network connection devices and our Fixed Wireless Access CPE devices. We also saw a shift in demand from our cable customers toward more I-CCAP chassis each quarter. That increase in demand contributed to our strong revenue performance in 2020 and has continued into 2021. We cannot guarantee that the heightened demand for residential broadband services will continue for the duration of the pandemic or after the pandemic ends. We similarly cannot guarantee that even to the extent the heightened demand for residential broadband services continues that we will continue to see heightened demand for our solutions. A decrease in demand for our solutions could have a material adverse impact on our revenue and results of operations.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Use of Proceeds

On December 14, 2017, ~~the Securities and Exchange Commission, or~~ the SEC declared our registration statement on Form S-1 (File No. 333-221658) for our initial public offering, or IPO, effective. The net offering proceeds to us from the IPO, after deducting underwriting discounts of $6.3 million and offering expenses payable by us totaling $4.1 million, were approximately $79.3 million. No offering discounts, commissions or expenses were paid directly or indirectly to any of our directors or officers (or their associates) or persons owning 10.0% or more of any class of our equity securities or to any other affiliates. There has been no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC on December 15, 2017 pursuant to Rule 424(b)(4). As of September 30, ~~2021,~~2022, we had not used any of the net offering proceeds and we have invested the proceeds into an investment portfolio with the primary objective of preserving principal and providing liquidity without significantly increasing risk.
