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~~wholly- owned subsidiaries in China, France, Canada, Ireland, Spain, ~~Colombia,~~ the Netherlands, Hong Kong, Australia, Germany, the United Kingdom, the United States and New Zealand.

The Company offers physical, virtual and cloud-native 5G infrastructure and customer premise networking equipment solutions to help communications service providers, or CSPs, transform and expand their public and private high-speed data and multi-service communications networks so they can meet the growing demand for bandwidth and new services. ~~The~~Through the development of cloud, access devices and cable products, the Company’s core and edge ~~broadband~~convergence technology enables 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 regardless of access technology. As technology has changed, the Company is now viewing offerings across three major product lines, cloud, access devices and cable, as opposed to our historical view of cable, wireless and fixed telco. Our revenue disclosures have been updated accordingly.

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 CSP industry. These risks include, but are not limited to, the level of capital spending by 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 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.

~~The~~Prior to December 31, 2022, the Company iswas 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~~provided 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 iswas issued or revised and it ~~has~~had different application dates for public or private companies, the Company iswas required to adopt the new or revised standard at or prior to the time private companies ~~are~~were required to adopt the new or revised ~~standard, provided that~~standard. As of December 31, 2022, the Company ~~continues to be~~no longer qualifies as an emerging growth ~~company. The JOBS Act provides that the decision~~company and will now be required to ~~take advantage of the extended transition period for complying with~~adopt new or revised ~~accounting~~ standards ~~is irrevocable.~~at the same time as other public companies.

The accompanying condensed consolidated balance sheet as of March 31, ~~2022,~~2023, the condensed consolidated statements of operations and comprehensive ~~(loss) income~~loss for the three months ended March 31, ~~2022~~2023 and ~~2021,~~2022, the condensed consolidated statements of cash flows for the three months ended March 31, ~~2022~~2023 and ~~2021~~2022, and the condensed consolidated statements of stockholders’ equity for the three months ended March 31, ~~2022~~2023 and ~~2021~~2022 are unaudited. The financial data and other information disclosed in these notes related to the three months ended March 31, ~~2022~~2023 and ~~2021~~2022 are also unaudited. The accompanying condensed consolidated balance sheet as of December 31, ~~2021~~2022 was derived from the Company’s audited consolidated financial statements for the year ended December 31, ~~2021~~2022, which was included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on ~~February 25, 2022~~March 15, 2023 (the “Annual Report on Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted 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, ~~2022~~2023 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. Certain prior period amounts have been reclassified to conform to the current period presentation.

Going Concern

In accordance with the accounting guidance related to the presentation of financial statements, when preparing financial statements for each annual and interim reporting period, management evaluates whether there are conditions or events that, when considered in the aggregate, raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. In making its assessment, management considered the Company’s current financial condition and liquidity sources including current funds available, forecasted future cash flows and conditional and unconditional obligations due over the next twelve months.

As described further in Note 9, Debt, the Company has debt outstanding that matures within one year. The Company currently does not have committed financing or available liquidity to meet such debt obligations if they were to become due in accordance with their current terms. On May 8, 2023, the Company entered into a Transaction Support Agreement (“TSA”) with an ad hoc committee of lenders (“Consenting Lenders”) representing approximately 60% of the $223,884 in aggregate principal currently outstanding, to extend the maturity date of the debt to December 2027. The Consenting Lenders have agreed, subject to certain terms and conditions set forth in the TSA, to exchange approximately $133,876 of their existing 2023 TLB Debt for a newly issued super-priority term loan B (the "2027 TLB Debt"). The TSA also provides that other holders of the existing 2023 TLB Debt that did not initially sign the TSA may execute a joinder to the TSA under certain conditions. Any such other holder that executes a joinder will be required, subject to the same terms and conditions, to exchange its 2023 TLB Debt for such 2027 TLB Debt. The Company will pay down the 2027 TLB Debt principal held by the Consenting Lenders by $40,000 using available cash on hand. Upon closing of the transactions contemplated by the TSA, which are subject to customary closing conditions and achieving certain participation thresholds as set forth therein, and are conditioned on the satisfaction or waiver of certain conditions precedent, including finalizing all definitive documents, management believes that the Company will have sufficient cash and cash equivalents to meet its working capital and capital expenditure needs and debt service obligations for at least the following 12 months. The Company has incurred and expects to continue to incur significant legal and advisory fees in developing its financing plans. There can be no assurance that the transactions contemplated by the TSA will be completed as contemplated, or at all. If the Company is unable to complete this transaction or any other alternative transactions, on favorable terms or at all, due to market conditions or otherwise, its financial condition could be materially adversely affected. Because of the uncertainty in refinancing outstanding debt, management has concluded that substantial doubt exists with respect to the Company's ability to continue as a going concern within one year after the date that these consolidated financial statements are issued.

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, 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~~disrupted the Company, 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, duringCompany's global supply chain. During the three months ended March 31, 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, whose availability was significantly exceeded by global demand. As a result, during the three months ended March 31,2023 and throughout 2022, the Company ~~continued to see~~experienced shipping bottlenecks and shortages of supply that resulted in ~~the Company’s~~its inability to fulfill certain customer orders within normal lead times. This adversely impacted the ~~Company’s~~Company's revenue and operating results for the three months ended March 31, 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.results. 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 if or when such effects will subside. This may prevent the Company from being able to fulfill its ~~customers’~~customers' orders in a timely manner or at all, which could lead to one or more of its customers ~~cancelling~~canceling their orders. 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.

In addition to the negative impact on the Company's business from global supply chain challenges related to COVID-19, the Company derived certain benefits from the pandemic that included decreases in certain operating expenses, such as travel and trade show expense, and benefited from certain U.S. government tax relief measures. These benefits began to gradually diminish during 2022 and the three months ended March 31, 2023, and may continue to do so as various geographies in which the Company operates continue to recover from the pandemic and government tax relief measures lapse.

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~~will 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. Other than the ~~agreement with Verizon Ventures LLC,~~reduction in workforce and TSA, both as discussed in Note ~~17,~~ 18, Subsequent Events, the Company has evaluated all subsequent events and determined that there are no additional 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 March 31, ~~2022~~2023 and December 31, ~~2021,~~2022, the Company’s cash and cash equivalents consisted of investments in money market mutual funds.

Restricted cash as of March 31, ~~2022~~2023 and December 31, ~~2021~~2022 consisted of a certificate of deposit of ~~$1,001,~~$1,017 and $1,013, respectively, pledged as collateral for a stand-by letter of credit required to support a contractual ~~obligation. Restricted cash also included~~obligation, as well as cash of ~~$2,100~~$2,100 pledged as collateral in connection with ~~five and~~ two letters of credit to support contractual obligations, ~~at March 31, 2022 and December 31, 2021, respectively.~~as further discussed in Note 16, Leases.

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:


	March 31, 2022		March 31, 2021		March 31, 2023		March 31, 2022
Cash and cash equivalents	$	168,580	$	144,961	$	112,495	$	168,580

	$	171,681	$	145,969	$	115,612	$	171,681

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 March 31, ~~2022~~2023 and December 31, ~~2021~~2022 consisted of the following:


	March 31, 2022		December 31, 2021		March 31, 2023		December 31, 2022
Current portion of accounts receivable, net:
Accounts receivable, net	$	48,029	$	85,689	$	47,442	$	74,407
Accounts receivable, extended payment terms		77		85		21		77

Accounts receivable, net of current portion:
Accounts receivable, extended payment terms		57		115
	$	48,163	$	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 also provides an overall expected credit loss amount, based on historical loss rates, in accordance with ASC 326, Credit Losses. 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.~~loss.

During the three months ended March 31, ~~2022~~2023 and ~~2021,~~2022, 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:

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

The Company values inventories at the lower of cost or net realizable value. The Company computes cost using the first-in first-out convention. Inventories are composed of hardware and related component parts of finished goods. The Company 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 condensed consolidated statements of operations and comprehensive loss.

The Company includes deferred inventory costs within inventory in its condensed consolidated balance sheets. Deferred inventory costs represent the cost of products that have been delivered to the customer for which revenue associated with the arrangement has been deferred as a result of not meeting all the required revenue recognition criteria, such as receipt of customer acceptance. The Company recognizes deferred inventory costs as cost of revenue in its condensed consolidated statements of operations and comprehensive loss when the related revenue is recognized.

Impact of Recently Adopted or Issued Accounting Standards

~~In October 2021, the Financial Accounting Standards Board,~~There have been no recently adopted or ~~FASB,~~ issued ~~Accounting Standards Codification Update (“ASU”) 2021-08,~~ ~~Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers~~, or ASU 2021-08. Under ASU 2021-08, an acquirer must recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. Effective January 1, 2022,accounting standards that are applicable to the Company ~~early adopted ASU 2021-08 on a prospective basis. The impact of adoption of this standard on the Company’s condensed consolidated financial statements 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~~, or ASU 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 aftersince December ~~15, 2021, and interim periods within fiscal years beginning after December 15,~~31, 2022. The Company has begun planning for adoption by implementing a new lease accounting software and by working to establish additional changes to internal processes to comply with all requirements upon adoption. The standard allows for, and the Company plans on using, a modified retrospective approach with comparatives under ASC 840, where entities would recognize a cumulative effect to retained earnings at the date of adoption without restating prior period balances or disclosure. Management is continuing to assess the impact of ASU 2016-02 on the Company’s condensed consolidated financial statements and the accompanying notes thereto.

~~In June 2016, the FASB issued ASU 2016-13,~~ ~~Measurement of Credit Losses on Financial Instruments~~, or ASU 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. The Company is currently evaluating the impact ASU 2016-13 will have on its consolidated financial statements.~~Other

Other than the disclosures above, there have been no changes to the significant accounting policies disclosed in Note 2 ~~“Summary~~Summary of Significant Accounting ~~Policies”~~Policies to the Company’s consolidated financial statements included in ~~the~~its Annual Report on Form 10-K for the fiscal year ended December 31, ~~2021.~~2022.

In addition, in conjunction with customers’ renewals of maintenance and support contracts, the Company offers an extended warranty for periods typically of one to three years for agreed-upon fees. In the event of a failure of a hardware product or software covered by these warranties, the Company must repair or replace the software or hardware or, if those remedies are insufficient, and at the discretion of the Company, provide a refund. The Company’s warranty reserve, which is included in accrued expenses and other current liabilities in the condensed consolidated balance sheets, reflects estimated material, labor and other costs related to potential or actual software and hardware warranty claims for which the Company expects to incur an obligation. The Company’s estimates of anticipated rates of warranty claims and the costs associated therewith are primarily based on historical information and future forecasts. The Company periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary. If the historical data used to calculate the adequacy of the warranty reserve are not indicative of future requirements, additional or reduced warranty reserves may be required.

AThe following table presents a summary of changes in the amount reserved for warranty costs for the three months ended March 31, ~~2022~~2023 and ~~2021 is as follows:~~2022:

~~As of March 31, 2022~~2023 and December 31, ~~2021, $277,475~~2022, $223,884 and ~~$278,225~~$226,009 in principal ~~amount,~~amounts, respectively, were outstanding under the Term Loan. Thus, as of March 31, 2023 and December 31, 2022, all of the Company's outstanding debt is payable in the year ending December 31, 2023 and is classified as a current liability in the accompanying condensed consolidated balance sheets.

On May 8, 2023, the Company entered into a TSA with an ad hoc committee of Consenting Lenders representing approximately 60% of the $223,884 in aggregate principal currently outstanding, to extend the maturity date of the debt to December 2027. The Consenting Lenders have agreed, subject to certain terms and conditions set forth in the TSA, to exchange approximately $133,876 of their existing 2023 TLB Debt for a newly issued super-priority term loan B (the “2027 TLB Debt”). The TSA also provides that other holders of the existing 2023 TLB Debt that did not initially sign the TSA may execute a joinder to the TSA under certain conditions. Any such other holder that executes a joinder will be required, subject to the same terms and conditions, to exchange its 2023 TLB Debt for such 2027 TLB Debt. The Company will pay down the 2027 TLB Debt principal held by the Consenting Lenders by $40,000 using available cash on hand. Upon closing of the transactions contemplated by the TSA, which are subject to customary closing conditions and achieving certain participation thresholds as set forth therein, and conditioned on the satisfaction or waiver of certain conditions precedent, including finalizing all definitive documents, management believes that the Company will have sufficient cash and cash equivalents to meet its working capital and capital expenditure needs and debt service obligations for at least the following 12 months. However, there can be no assurance that the transactions contemplated by the TSA will be completed as contemplated, or at all. If the Company is unable to complete this transaction or any other alternative transactions, on favorable terms or at all, due to market conditions or otherwise, its financial condition could be materially adversely affected. Thus, there is substantial doubt about the Company's

ability to continue as a going concern. See also the Going Concern subsection of Note 1, Nature of Business and Basis of Presentation.

Borrowings under the Term Loan bear interest at a floating rate, which can be either a Eurodollar rate plus an applicable margin or, at the Company’s 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%~~(0.50%) per annum and (z) a one-month Eurodollar rate plus ~~1.00%~~1.00% per annum) plus an applicable margin. The applicable margin for borrowings under the Term Loan is ~~4.00%~~4.00% per annum for Eurodollar rate loans (subject to a ~~1.00%~~1.00% per annum interest rate floor) and ~~3.00%~~3.00% per annum for base rate loans. The interest rate payable under the Term Loan is subject to an increase of ~~2.00%~~2.00% per annum during the continuance of any payment default.

For Eurodollar rate loans, the Company 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. The Company has the right to convert Eurodollar rate loans into base rate loans and the right to convert base rate loans into Eurodollar rate loans at its 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 March 31, ~~2022 and December 31, 2021,~~2023, the interest rate on the Term ~~Loans~~Loan was ~~5.00%~~8.84% per annum, which was based on a one-month Eurodollar ~~rates, at the applicable floor~~rate of ~~1.00%~~4.84% per annum plus the applicable margin of ~~4.00%~~4.00% per annum for Eurodollar rate loans. As of December 31, 2022, the interest rate on the Term Loan was 8.38% per annum, which was based on a one-month Eurodollar rate of 4.38% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans.

Upon entering into the Term Loan, the Company incurred debt issuance costs of ~~$7,811,~~$7,811, which were initially recorded as a reduction of the debt liability and are amortized to interest expense using the effective interest method from the issuance date of the Term Loan until the maturity date. The Company made principal payments of ~~$750~~$750 during each of the three months ended March 31, ~~2022~~2023 and ~~2021 under the Term Loan.~~2022. Interest expense for the Term Loan, including the amortization of debt issuance costs, totaled ~~$3,777~~$4,909 and ~~$3,869~~$3,777 for the three months ended March 31, 2023 and 2022, respectively.

Additionally, on October 27, 2022, the Company's board of directors authorized the use of up to $50,000 of cash to fund the partial repurchase of debt outstanding under the Term Loan. Subsequent to this authorization, the Company repurchased a portion of its outstanding Term Loan from certain of its debt holders. During the three months ended March 31, 2023, the Company made a payment of $1,237 to retire $1,375 of its outstanding debt. The Company recognized a gain on extinguishment of debt, net of fees, of $133, and ~~2021, respectively.~~also recognized $4 of interest expense for the pro-rata portion of unamortized debt issuance costs attributed to the debt repurchased. Total payments made under this authorization through March 31, 2023 amounted to $47,116, which were paid using funds included in cash and cash equivalents in the condensed consolidated balance sheets. Based on the applicable fair value of debt repurchased, the amount of outstanding principal of the Term Loan that was retired was $50,591.

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%~~1.0% of the original principal amount of the Term Loan of ~~$300,000,~~$300,000, 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, the Company is required to compensate the lenders for any funding losses and expenses incurred as a result of the prepayment.

In addition, the Company is required to make mandatory prepayments under the Term Loan with respect to (i) ~~100%~~100% of the net cash proceeds from certain asset dispositions (including casualty and condemnation events) by the Company or certain of its subsidiaries, subject to certain exceptions and reinvestment provisions, (ii) ~~100%~~100% of the net cash proceeds from the issuance or incurrence of any additional debt by the Company or certain of its subsidiaries, subject to certain exceptions, and (iii) ~~50%~~50% of the Company’s excess cash flow, as defined in the credit agreement, subject to reduction upon its achievement of specified performance targets. In accordance with these provisions, no mandatory early prepayment was required to be paid by the Company during the three months ended March 31, 2023.

The Term Loan is secured by, among other things, a first priority security interest, subject to permitted liens, in substantially all of the Company’s assets and all of the assets of certain of its subsidiaries and a pledge of certain of the stock of certain of its 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 the Company’s total net leverage

ratio, such as the Company’s ability to pay dividends ~~certain of which are based upon the Company’s total net leverage ratio.~~and repurchase outstanding shares. The Company was in compliance with all covenants as of March 31, ~~2022~~2023 and December 31, ~~2021.~~2022.

On February 21, 2019, the Company announced a stock repurchase program authorizing it to repurchase up to ~~$75,000~~$75,000 of the Company’s common stock. The Company repurchased ~~205~~204 shares, at a cost of ~~$1,192,~~$1,192, including commissions, during the three months ended March 31, 2022. There were 0no repurchases made during the three months ended March 31, ~~2021.~~2023. As of March 31, ~~2022, $60,234~~2023, $60,234 remained authorized for repurchases of the Company’s common stock under the stock repurchase program. However, based on the Company's net leverage ratio at March 31, 2023, as described in Note 9, Debt, the Company's ability to repurchase shares is currently restricted. The stock repurchase program has no expiration date and does not require the Company to purchase a minimum number of shares, and the Company may suspend, modify or discontinue the stock repurchase program at any time without prior notice.

On April 18, 2022, the Company entered into a Securities Purchase Agreement (the “SPA”) with Verizon Ventures LLC providing for the private placement of an aggregate of 9,323 shares (the “Shares”) of the Company's common stock, par value $0.001 per share at a price of $4.24 per share, for an aggregate purchase price of approximately $39,530. Issuance costs related to this transaction totaled $160 and were net against the amount recorded to additional paid in capital on the condensed consolidated balance sheet. The Company filed a resale registration statement for the Shares with the SEC on May 17, 2022.

The weighted-average grant-date fair value of options granted during the three months ended March 31, 2023 and 2022 was $0.54and ~~2021 was $1.72 and $3.42~~$1.72 per share, respectively. Cash proceeds received upon the exercise of options were ~~$79~~$2 and ~~$574~~$79 during the three months ended March 31, ~~2022~~2023 and ~~2021,~~2022, respectively. The intrinsic value of stock options exercised during the three months ended March 31, 2023 and 2022 was $1and ~~2021 was $76 and $805,~~$76, respectively. The aggregate intrinsic value is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the Company’s common stock.

The Company withheld ~~318~~1,369 and ~~593~~318 shares of common stock in settlement of employee tax withholding obligations due upon the vesting of RSUs and PSUs during the three months ended March 31, 2023 and 2022, ~~and 2021,~~ respectively.

During the three months ended March 31, ~~2021,~~2022, the Company granted PSUs to certain employees that vest over a three-year period based on the achievement of performance goals and continued performance of services. ~~The performance goals~~All PSUs granted prior to the three months ended March 31, 2022, and a portion of PSUs granted during the three months ended March 31, 2022, consist solely of market-based vesting conditions, determined by the Company’s level of achievement of pre-established parameters relating to the performance of the Company’s stock price as set by the ~~Board~~board of ~~Directors.~~directors. Vesting for these market-based PSUs may occur at any time during the three-year period. The remaining portion of PSUs granted during the three months ended March 31, 2022 consist of performance-based vesting conditions determined by the Company's achievement of performance targets with respect to a certain customer agreement. Vesting for these performance-based PSUs may occur in varying percentages on January 1, 2023, 2024, and 2025. No PSUs were granted during the three months ended March 31, 2023.

A summary of PSU activity for the three months ended March 31, 2023 is as follows:

During the three months ended March 31, 2023, the Company recognized $7,237of revenue that was included in deferred revenue in the condensed consolidated balance sheet as of December 31, 2022. During the three months ended March 31, 2022, the Company recognized ~~$5,636~~$5,636 of revenue that was included in deferred revenue in the condensed consolidated balance sheet as of December 31, 2021. ~~For the three months ended March 31, 2021, the Company recognized $7,010 of revenue that was included in deferred revenue as of December 31, 2020.~~

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 March 31, 2022 and 2021, the Company recorded interest income of $5 and $6,years~~respectively, which was recorded in the condensed consolidated statements of operations and comprehensive (loss) income.~~ .

14. 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. Since the Company operates as one operating segment, all required financial segment information can be found in these condensed consolidated financial statements.

During the three months ended March 31, ~~2022~~2023 and ~~2021,~~2022, the Company recognized selling, general and administrative expenses of ~~$31~~$28 and ~~$25~~$31 related to these awards.

As a result of the Company's SPA with Verizon Ventures LLC on April 18, 2022 (see Note 10, Stockholders Equity), Verizon Communications Inc. and its subsidiaries (“Verizon and Affiliates”) collectively became a principal stockholder of the Company through its ownership of common stock. Verizon and Affiliates are customers of the Company.

During the three months ended March 31, 2023, the Company recognized revenue of $2,997 from transactions with Verizon and Affiliates, and amounts received in cash resulting from revenue transactions with Verizon and Affiliates during the three months ended March 31, 2023 totaled $6,044. As of March 31, 2023 and December 31, 2022, amounts due from Verizon and Affiliates totaled $4,648 and $6,044, respectively, and were included in accounts receivable, net in the condensed consolidated balance sheet. As of March 31, 2023 and December 31, 2022, revenue from transactions that did not meet the criteria for recognition totaling $19,630 and $18,094, respectively, with Verizon and Affiliates were included in deferred revenue in the condensed consolidated balance sheet.

16. Leases

The Company leases manufacturing, warehouse and office space in the United States, Ireland, China, Hong Kong, Spain and Australia under non-cancelable operating leases with expiration dates through 2028, as well as various equipment leases. The leases have remaining lease terms of 1 year to 6 years, some of which contain options to extend the leases for up to 3 additional years and some which include options to terminate the leases within 1 year. The lease agreements contain lease and non-lease components, which are generally accounted for together.

After the adoption of ASC 842, the Company determines if an arrangement is a lease at inception. Operating leases are included in the operating lease right-of-use, (“ROU”), assets and the short-term and long-term lease liabilities on the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the leases do not provide an implicit rate, the Company used its incremental borrowing rate based on information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Pursuant to the terms of the lease agreement for the Company’s Australia office, the Company obtained six standby letters of credit in the amount of approximately $2,100 as security on the lease obligation. The letters of credit are classified as restricted cash in the accompanying condensed consolidated balance sheets as of March 31, 2023 and December 31, 2022.

As of March 31, 2023, the remaining accrued expense balance, representing the estimated net present value of the remaining payments, plus the estimated cost of other non-monetary obligations under the settlement deed was $9,784, as shown in Note 6, Accrued Expenses and Other Current Liabilities.

18. Subsequent Events

~~Securities Purchase Agreement~~In April 2023, the Company approved a plan to reduce the Company's current workforce by approximately 135 employees, representing approximately 13% of the Company's total workforce. The Company expects to incur total estimated one-time cash charges of approximately $2,100 in connection with ~~Verizon Ventures LLC~~the reduction in force, primarily consisting of severance payments and other employee-related costs. The Company expects that the majority of these charges will be incurred in the second quarter of 2023 and that the reduction in workforce will be substantially complete by June 30, 2023.

As described in the Going Concern subsection of Note 1, Nature of Business and Basis of Presentation, and Note 9, Debt, On ~~April 18, 2022,~~May 8, 2023, the Company entered into a ~~Securities Purchase~~Transaction Support Agreement ~~(the “SPA”~~(“TSA”) with ~~Verizon Ventures LLC providing for the private placement~~an ad hoc committee of ~~an aggregate of 9,323 shares (the “Shares”~~lenders (“Consenting Lenders”) representing approximately 60% of the ~~Company’s common stock, par value $0.001 per share, at~~$223,884 in aggregate principal currently outstanding, to extend the maturity date of the debt to December 2027.

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 March 31, ~~2021~~2022 and March 31, ~~2020,~~2021, please refer to our Quarterly Report on ~~form~~Form 10-Q filed with the SEC on ~~April 30, 2021.~~May 4, 2022.

Overview

With our physical, virtual and cloud-native 5G ~~infrastructure~~broadband and customer premise networking equipment solutions, we help our CSP customers transform and expand their public and private high-speed data and multi-service communications networks so they can meet the growing demand for bandwidth and new services. ~~Our~~Through our deployment of cloud, access devices and cable products, our core and edge convergence technology enables CSPs and enterprises to cost-effectively and dynamically increase network speed, add bandwidth capacity and new services, reduce network complexity, and reduce operating and capital expenditures regardless of access technology.

We offer ~~scalable~~end-to-end cloud-native, virtual, physical and distributed infrastructure and customer premise network solutions that enable our customers to provide wireless and fixed-line broadband services to consumers and enterprises. Our solutions are scalable so that CSPs 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.

~~COVID-19 Pandemic~~Global and Macroeconomic Considerations

~~The ongoing COVID-19 pandemic presents various risks~~Rising Inflation and Interest Rates

Supply chain disruption and other economic conditions have led to ~~us,~~a recent rise in inflation, which ~~could continue~~has caused increases in the costs to ~~have a material effect upon the estimates~~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 judgments relied upon by management in preparing these condensed consolidated financial statements. While we remain fully operational, during the three months ended March 31, 2022, the effects of the COVID-19 pandemic on the global supply chain had a significant adverse effectservices, 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 in the future raise interest rates in response to concerns about inflation. Increases in interest rates, especially if coupled with reduced government spending and volatility in financial ~~results.~~markets, may have the effect of further increasing economic uncertainty and heightening these risks. In ~~particular, certain~~an inflationary environment, due to our fixed price agreements, we may be unable to raise the prices of our products ~~utilize components whose availability was significantly exceeded by global demand. As~~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.

Banking Institution Liquidity

In March 2023, the bank failures of Silicon Valley Bank and Signature Bank created significant market disruption and uncertainty within the U.S. banking sector, particularly with respect to regional banks, and a number of other financial institutions experienced turbulence and a precipitous decline in market value. We are closely monitoring ongoing events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally. While we do not hold a cash balance at Silicon Valley Bank or Signature Bank, we have historically held our cash in a limited number of financial institutions. We

do not hold a cash balance at either Silicon Valley Bank or Signature Banks, and we do not believe we have exposure to loss as a result ~~during~~of the ~~three months ended March 31,~~failure of either institution.

COVID-19 Pandemic

The COVID-19 pandemic disrupted our global supply chain. Throughout 2022 and 2021, we ~~continued to see~~experienced shipping bottlenecks and 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 months~~years ended ~~March~~December 31, ~~2022. Additionally, shipping bottlenecks~~2022 and ~~delays further negatively affected our ability to timely fulfill customer orders, thereby delaying our ability to consummate sales and recognize revenue.~~2021. 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~~canceling 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.

In addition to the negative impact on our business from global supply chain challenges related to COVID-19, we derived certain benefits from the pandemic that included decreases in certain operating expenses, such as travel and trade show expense, and benefited from certain U.S. government tax relief measures. These benefits began to gradually diminish throughout 2022 and may continue to do so as the various geographies in which we operate continue to recover from the pandemic and government tax relief measures lapse.

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.

For the three months ended March 31, 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 three months ended March 31, 2021, we recognized a reduction to cost of goods sold of $0.3 million and a reduction in operating expenses of $2.1 million, in connection with a payroll tax credit under the CARES Act. We will continue to evaluate the impact of the CARES Act on our financial position, results of operations, and cash flows.

Due to the above circumstances, ~~and as described generally in this Quarterly Report on Form 10-Q,~~ our results of operations for the three months ended March 31, 2023 and 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

years.customers, who may temporarily accelerate or curtail spending on investments in current and/or new technologies, delay new equipment evaluations and trials 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. For the three months ended March 31, 2022, we did see certain delays in our supply chain that adversely impacted delivery schedules to our customers. If COVID-19 were to have such effects in the future, there would likely be a material adverse impact 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 impact of COVID-19 could have a material adverse impact on our results of operations in the near to medium term.

The enactment of the Tax Cuts and Jobs Act in December 2017, requires 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. The change in provision for income taxes for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, was primarily due to the change in tax law, which results in significant forecasted U.S. income tax for the year and a significant corresponding increase in deferred tax assets, which is offset by a full valuation allowance.

Liquidity and Capital Resources

As of March 31, ~~2022,~~2023, we had cash, cash equivalents and restricted cash of ~~$171.7~~$112.5 million and net accounts receivable of ~~$48.2~~$47.5 million.

We had outstanding borrowings under our $300 million term loan facility, or the Term Loan (which is more fully described below under the heading "Term Loan and Revolving Credit Facilities") of $223.9 million at December 31, 2022, which matures on December 20, 2023. Because the Term Loan matures within one year and the Company does not currently have committed financing or available liquidity to meet such debt obligations if they were to become due in accordance with their current terms, there is substantial doubt about our ability to continue as a going concern. We continue to work with potential lenders to refinance the existing debt. Our future capital requirements may vary materially from those currently planned and will depend on many factors, including our rate of revenue growth; the mix of revenues and impact on related gross margins; 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 our sales and marketing activities; the 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.

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 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 purchases of inventory, 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, 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 three months ended March 31, ~~2022~~,2023, cash ~~provided by~~used in operating activities was ~~$18.1~~$8.4 million, primarily resulting from our net loss of $31.7 million, partially offset by net cash provided by changes in our operating assets and liabilities of ~~$43.8~~$16.6 million and net non-cash adjustments of ~~$6.8 million, partially offset by our net loss of $32.6~~$6.7 million. Net cash provided by changes in our operating assets and liabilities during the three months ended March 31, ~~2022~~2023 was primarily due to a ~~$37.5~~$27.7 million decrease in accounts receivable due to collections during the period; a ~~$21.3~~$3.4 million decrease in prepaid income taxes; a ~~$9.0 million increase in accrued income taxes; and a $4.1~~$4.7 million increase in deferred revenue due to the timing of revenue ~~recognition.~~recognition; and a $2.3 million increase in accrued expenses due to the timing of certain accrual payments. These sources of cash were partially offset by a ~~$13.7~~$13.9 million decrease in accounts payable due to timing of vendor payments; a ~~$13.7~~$2.6 million decrease in accrued ~~expenses due to the timing of certain accrual payments;~~income taxes; a ~~$0.5 million increase in inventory; and a $0.2~~$3.3 million increase in prepaid expenses and ~~other assets.~~a $1.2 million increase in inventory.

Financing Activities

Net cash used in financing activities during the three months ended March 31, ~~2022~~2023 was ~~$3.4~~$4.9 million, ~~consisting primarily~~which was mainly due to debt principal repayments of $2.0 million and employee taxes paid related to the net share settlement of equity awards of ~~$1.5~~$2.9 million, primarily due to ~~certain~~ RSUs that vested during ~~the~~ ~~three months ended March 31, 2022; repurchases of treasury stock of $1.2 million; and debt principal repayments of $0.8 million. These payments were partially offset by proceeds from the exercise of stock options of $0.1 million.~~

~~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 (“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 March 31, 2022 and December 31, 2021, we had borrowings of $277.5 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 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 ~~March 31, 2022 and~~ 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 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 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.

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, such as our ability to pay dividends, certain of which are based upon our total net leverage ratio. As of March 31, 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 $171.7 million as of March 31, 2022, $107.8 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 March 31, 2022, we had $29.7 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.

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 the law change, 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 Securities Purchase Agreement (the “SPA”) with Verizon Ventures LLC providing for the private placement of an aggregate of 9.3 million shares (the “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 are required to prepare and file a resale registration statement with the Securities and Exchange Commission (the “SEC”) within 45 days of the closing of the SPA, 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 three months ended March 31, ~~2022, we repurchased approximately 0.2 million shares for~~2023.

Cash Flows from Future Operations

Subject to successful completion of a total cost of approximately $1.2 million. During the three months ended March 31, 2021 we did not repurchase any shares. As of March 31, 2022, approximately $60.2 million remained authorized for repurchasesrefinancing of our ~~common stock~~

~~under the stock repurchase program.~~ ~~The stock repurchase program has no expiration date and does not require us to purchase a minimum number of shares, and~~Term Loan, we ~~may suspend, modify or discontinue the stock repurchase program at any time without prior notice.~~

We believe our existing cash and cash equivalents and anticipated cash flows from future operations 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. Due to the risk that we may be unable to successfully complete a refinancing of a sufficient portion of the outstanding balance prior to maturity or otherwise satisfy our repayment obligations, there is 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

•

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 March 31, 2023 and December 31, 2022, we had borrowings of $223.9 million and $226.0 million, respectively, outstanding under the Term Loan. On December 20, 2021, the revolving credit facility matured.

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.

On May 8, 2023, we entered into a Transaction Support Agreement (“TSA”) with an ad hoc committee of lenders (“Consenting Lenders”) representing approximately 60% of the $223.9 million in aggregate principal currently outstanding, to extend the maturity date of the debt to December 2027. The Consenting Lenders have agreed, subject to certain terms and conditions set forth in the TSA, to exchange approximately $133.9 million of their existing 2023 TLB Debt for a newly issued super-priority term loan B (the "2027 TLB Debt"). The TSA also provides that other holders of the existing 2023 TLB Debt that did not initially sign the TSA may execute a joinder to the TSA under certain conditions. Any such other holder that executes a joinder will be required, subject to the same terms and conditions, to exchange its 2023 TLB Debt for such 2027 TLB Debt. We will pay down the 2027 TLB Debt principal held by the Consenting Lenders by $40.0 million using available cash on hand. Upon closing of the transactions contemplated by the TSA, which are subject to customary closing conditions

and achieving certain participation thresholds as set forth therein, and conditioned on the satisfaction or waiver of certain conditions precedent, including finalizing all definitive documents, management believes that we will have sufficient cash and cash equivalents to meet our working capital and capital expenditure needs and debt service obligations for at least the following 12 months. However, there can be no assurance that the transactions contemplated by the TSA will be completed as contemplated, or at all. If we are unable to complete this transaction or any other alternative transactions, on favorable terms or at all, due to market conditions or otherwise, our financial condition could be materially adversely affected. Thus, there is substantial doubt about our ability to continue as a going concern. See also the Going Concern subsection of Note 1, Nature of Business and Basis of Presentation.

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 March 31, 2023, the interest rate on the Term Loan was 8.84% per annum, which was based on a one-month Eurodollar rate of 4.84% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans. As of December 31, 2022, the interest rate on the Term Loan was 8.38% per annum, which was based on a one-month Eurodollar rate of 4.38% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans.

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 that are currently in effect based upon our total net leverage ratio, such as our ability to pay dividends and repurchase outstanding shares. As of March 31, 2023 and December 31, 2022, we were in compliance with all applicable covenants of the Term Loan.

Restructuring

In April 2023, we approved a plan to reduce our current workforce by approximately 135 employees, representing approximately 13% of our total workforce. We expect to incur total estimated one-time cash charges of approximately $2.1 million in connection with the reduction in force, primarily consisting of severance payments and other employee-related costs. We expect that the majority of these charges will be incurred in the second quarter of 2023 and that the reduction in workforce will be substantially complete by June 30, 2023.

Together with certain other actions undertaken by management, the expected net reduction in operating expenses for the remainder of 2023 is approximately $5.5 million.

Tax Cuts and Jobs Act

Of our total cash and cash equivalents of $112.5 million as of March 31, 2023, $44.3 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 March 31, 2023, applicable U.S. corporate income taxes have been provided on substantially all of our accumulated earnings of foreign subsidiaries.

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.

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 three months ended March 31, 2023, we did not repurchase any shares. During the three months ended March 31, 2022, we repurchased approximately 0.2 million shares for a total cost of approximately $1.2 million. As of March 31, 2023, approximately $60.2 million remained authorized for repurchases of our common stock under the stock repurchase program. However, based on our net leverage ratio at March 31, 2023, 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, operating leases and purchase agreements with our contract manufacturers and suppliers. 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, ~~2021.~~2022.

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.~~GAAP. 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 adoption of ASU 2021-08, as described in Note 2 of the above notes to the condensed consolidated financial statements, 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, 2021.

Recent Accounting Pronouncements

Refer to the “Summary of Significant Accounting Policies” footnote within our condensed consolidated financial statements included ~~elsewhere~~ in this Quarterly Report on Form 10-Q for our analysis of recent accounting pronouncements that are applicable to our business.

~~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.33

There have been no material changes to our market risks related to foreign currency exchange, interest rate sensitivity and inflation as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Interim Chief Executive Officer and Chief Financial Officer, ~~has evaluated~~after evaluating 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~~10-Q, has concluded that, based on such evaluation and as a result of the material weaknesses discussed below, our 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~~ were not effective to ensure that information required to be disclosed by ~~a company~~us in the reports that ~~it files~~we file or ~~submits~~submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the ~~Securities and Exchange Commission’s~~SEC's rules and ~~forms. Disclosure controls~~forms 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~~Interim Chief Executive Officer and ~~principal financial officers,~~Chief Financial Officer, or persons performing similar functions, 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~~

Notwithstanding the identified material weaknesses, our management ~~necessarily applies its judgment~~believes the unaudited condensed consolidated financial statements included 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 fairly present, in all material respects, our ~~Chief Executive Officer~~financial condition, results of operations and ~~Chief Financial Officer have concluded that~~cash flows as of and for the periods presented in accordance with U.S. GAAP.

Material Weaknesses and Remediation of Material Weaknesses

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Internal control over financial reporting includes those policies and procedures that:

•

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

•

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

•

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As disclosed in the Company’s Annual Report on Form 10-K filed with the SEC on March 15, 2023, management and our independent registered public accounting firm identified material weaknesses in our internal control over financial reporting. A material weakness is a weakness or deficiency, or combination of deficiencies, in internal control over financial reporting such ~~date,~~that there is a reasonable possibility that a material misstatement of our ~~disclosure~~financial statements will not be prevented or detected on a timely basis. Management and our independent registered public accounting firm identified material weaknesses that are pervasive in our internal control processes and involve the control environment, risk assessment, control activity, information and communication, and monitoring components of the Committee of Sponsoring Organizations of the Treadway Commission framework. Specifically, the material weaknesses relate to: an insufficiently staffed finance organization with the requisite knowledge or skills in and ability to focus on internal control over financial reporting matters; not fully designing, implementing and monitoring policies or financial reporting controls that identify and sufficiently mitigate risks of material misstatement to the financial statements; and insufficient design, implementation and monitoring of general information technology controls to support the effective operation of financial controls. Because of the material weaknesses described above, our management believes that our internal control over financial reporting was not effective.

Remediation of the Material Weaknesses in Internal Control Over Financial Reporting

Immediately following the identification of the material weaknesses described above, and with the oversight of the audit committee of our board of directors, we commenced a process to remediate the underlying causes of these material weaknesses, enhance the control environment and strengthen our internal control over financial reporting. We are committed and are taking steps necessary to remediate the control deficiencies that caused the above material weaknesses by implementing changes to

our internal control over financial reporting. We have begun the process to remediate the material weakness and will continue our efforts through fiscal 2023. Our plans for remediation include the following:

•

We have added and will continue the process of adding a sufficient number of qualified personnel within our accounting function to establish the appropriate level of resources to ensure successful remediation, and thereafter, ongoing maintenance of adequate internal controls over financial reporting. We have recently hired a new Director of Revenue and, an additional IT resource, we have engaged accounting advisory consultants to provide additional oversight and expertise to enhance our period end close, technical accounting, and financial reporting capabilities, and we will continue to utilize such additional resources as necessary;

•

As these resources are added, we will continuously evaluate the assignment of responsibilities, internal and external, associated with the performance of control activities and will continue to consider hiring additional accounting, finance and IT personnel as necessary;

•

We have delivered, and will continue delivering, training on a regular basis related to internal control over financial reporting to our team members including, but not limited to, finance and accounting personnel, to educate control owners and enhance policies to ensure that all design elements of control activities are addressed in the performance of control activities;

•

We will continue the process of implementing and/or enhancing control activities, including automating certain manual processes, which is expected to help increase the efficiency of processing transactions and produce accurate and timely information;

•

We have engaged third-party consultants to continue to re-assess our control environment and assist with re-designing existing controls and the development of new controls where needed, including Information Technology General Controls. This effort will also include updating and improving existing control documentation as well as developing and performing ongoing and separate evaluations of our internal control environment to ascertain whether the components of internal control are present and functioning at an appropriate level; and

•

In addition, under the direction of the audit committee of the board of directors, management will continue to review and make necessary changes to the overall design of our internal control environment, as well as to refine and monitor policies and procedures ~~were effective.~~to improve the overall effectiveness of internal control over financial reporting of our company.

When fully implemented and operational, we believe the measures described above will remediate the material weaknesses we have identified and strengthen our internal control over financial reporting. As we continue to evaluate and work to improve our internal control over financial reporting, our management may determine to take additional measures.

The measures we are implementing are subject to continued management review supported by confirmation and testing, as well as audit committee oversight. Management and the audit committee of the board of directors remain committed to the implementation of remediation efforts to address the material weaknesses. We will continue to implement measures to remedy our internal control deficiencies, though there can be no assurance that our efforts will be successful or avoid potential future material weaknesses. In addition, until remediation steps have been completed and are operated for a sufficient period of time, and subsequent evaluation of their effectiveness is completed, the material weakness previously disclosed, and as described above, will continue to exist.

Changes in Internal Control over Financial Reporting

~~There~~Except as otherwise noted above under “Remediation of Material Weaknesses in Internal Control Over Financial Reporting” including the on-going remediation efforts described, 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. By letter dated April 11, 2022, plaintiff voluntarily withdrew its unperfected 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. By letter dated April 8, 2022, plaintiff voluntarily withdrew its unperfected appeal.

No amounts have been accrued for any of the putative class action lawsuits referenced above as of March 31, 2022, 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, ~~2021,~~2022, or the ~~2021~~2022 Annual Report on Form 10-K, which could materially affect our business, financial condition or future results. ~~There~~As a supplement to the risk factors identified in the 2022 10-K, below we have set forth a new risk factor (regarding inflation). Other than as provided below, there have been no material changes from the risk factors previously disclosed in the ~~2021~~2022 10-K.

If we are unable to hire, retain, train and motivate qualified personnel and senior management, our business, financial condition, results of operations and prospects could be adversely affected.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel, particularly software engineering and sales personnel. Competition for highly skilled personnel is often intense, particularly in the greater Boston region where we are headquartered, and we may not be able to attract and retain the highly skilled employees that we need to support our business. Many of the companies with which we compete for experienced personnel have greater resources than we have to provide more attractive compensation packages and other amenities. Research and development personnel are aggressively recruited by startup and growth companies, which are especially active in many of the technical areas and geographic regions in which we conduct product development. In addition, in making employment decisions, particularly in the high-technology industry, job candidates often consider the value of the stock-based compensation they are to receive in connection with their employment. Declines in the market price of our stock could adversely affect our ability to attract, motivate or retain key employees. If we are unable to attract or retain qualified personnel, or if there are delays in hiring required personnel, our business, financial condition, results of operations and prospects could be materially adversely affected.

Also, to the extent we hire personnel from competitors, or from certain customers or other third parties whose employees we have agreed not to solicit, we may be subject to allegations that such personnel have been improperly solicited, that such personnel have divulged proprietary or other confidential information, or that former employers own certain inventions or other work product. Such claims could result in litigation.

Our future performance also depends on the continued services and continuing contributions of our senior management to execute our business plan and to identify and pursue new opportunities and product innovations. Our employment arrangements with our employees do not require that they continue to work for us for any specified period, and therefore, they could terminate their employment with us at any time. Further, the loss of members of our senior management team, sales and marketing team or engineering team, or any difficulty attracting or retaining other highly qualified personnel in the future, could significantly delay or prevent the achievement of our development and strategic objectives, which could materially adversely affect our business, financial condition, results of operations and prospects.

On March 14, 2023, Jerry Guo announced his retirement from his positions as president and chief executive officer, and our board of directors appointed Edward Durkin, our chief financial officer, as interim chief executive officer. We are currently conducting a search for a full-time chief executive officer. Leadership transitions can be inherently difficult to manage, and an inadequate transition to a new chief executive officer may cause disruption, adversely affecting our financial performance and ability to meet operational goals and strategic plans. Management turnover also inherently causes some loss of institutional knowledge, which can negatively affect strategy and execution. In addition, competition for top management is high and it may take months to find a candidate that meets our requirements. If we are unable to attract and retain qualified management personnel, our business could suffer.

We do not maintain “key person” life insurance on our officers, directors or key employees.

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 March 31, ~~2022,~~2023, 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.

On February 21, 2019, we announced that our Board of Directors authorized the repurchase of up to $75.0 million of our common stock under a stock repurchase program. From inception through March 31, 2023, we repurchased approximately 3.6 million shares under the program. The stock repurchase program has no expiration date and does not require us to purchase a minimum number of shares. We may suspend, modify or discontinue the stock repurchase program at any time without prior notice. However, based on our net leverage ratio at March 31, 2023, our ability to repurchase shares is currently restricted.
