Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact contained in this Quarterly Report on Form 10-Q, including statements regarding our future results of operations and financial position, business strategy and plans and objectives of management for future operations, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as “may,” “might,” “should,” “expects,” “plans,” “anticipates,” “would,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions. The forward-looking statements in this Quarterly Report on Form 10-Q are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and are subject to a number of risks, uncertainties and assumptions described in the “Risk Factors” section and elsewhere in this Quarterly Report on Form 10-Q. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Some of the key factors that could cause actual results to differ from our expectations include:

•

our inability to fulfill our customers’ orders due to supply chain delays, access to key commodities or technologies or events that impact our manufacturers or their suppliers;

•

our ability to anticipate technological shifts;

•

our ability to generate positive returns on our research and development;

•

changes in the rate of communications service providers’ (“CSPs”), deployment of, and investment in, ultra-broadband network capabilities;

•

the lack of predictability of revenue due to lengthy sales cycles and the volatility in capital expenditure budgets of CSPs;

•

our ability to maintain and expand operating profit and net income;

•

the sufficiency of our cash resources and needs for additional financing;

•

our ability to further penetrate our existing customer base and obtain new customers;

•

changes in our pricing policies, whether initiated by us or as a result of competition;

•

the amount and timing of operating costs and capital expenditures related to the operation and expansion of our business;

•

the potential impact of the ongoing COVID-19 pandemic, which is highly uncertain and will depend on future developments on our business, our suppliers, our logistics suppliers and our customers;

•

the actual or rumored timing and success of new product and service introductions by us or our competitors or any other change in the competitive landscape of our industry, including consolidation among our competitors or customers;

•

our ability to successfully expand our business domestically and internationally, including our ability to maintain the synergies we have realized from our acquisition of NetComm Wireless Limited, or NetComm;

•

insolvency or credit difficulties confronting our customers, which could adversely affect their ability to purchase or pay for our products and services, or confronting our key suppliers, which could disrupt our supply chain;

•

future accounting pronouncements or changes in our accounting policies;

•

stock-based compensation expense;

•

our overall effective tax rate, including impacts caused by the relative proportion of foreign to United States (“U.S.”) income, the amount and timing of certain employee stock-based compensation transactions, changes in the valuation of our deferred tax assets and any new legislation or regulatory developments;

•

increases or decreases in our expenses caused by fluctuations in foreign currency exchange rates;

•

the costs and possible outcomes of any legal actions or proceedings against us, including those described under “Part II, Item 1—Legal Proceedings”;

•

general economic conditions, both domestically and in foreign markets;

•

our ability to obtain and maintain intellectual property protection for our products; and

•

our use of proceeds from our initial public offering.

Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events or otherwise.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except per share amounts)

(Unaudited)

1. Nature of Business and Basis of Presentation

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

The Company offers physical, virtual and cloud-native 5G infrastructure and customer premise networking equipment solutions to help 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 Company’s core and edge broadband 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.

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

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

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

2. Summary of Significant Accounting Policies

Use of Estimates

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

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

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

The COVID-19 pandemic presents various risks to the Company, which could continue to have a material effect upon the estimates and judgments relied upon by management in preparing these condensed consolidated financial statements. While the Company remains fully operational, during the three 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, 2022, the Company continued to see shortages of supply that resulted in the Company’s inability to fulfill certain customer orders within normal lead times. This adversely impacted the Company’s revenue and operating results for the three 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. The Company also experienced, in some cases, significant increases in shipping costs. While the Company continues to work with its supply chain, contract manufacturers, logistics partners, and customers to minimize the extent of such impacts, the Company expects the effects of global supply chain issues to continue and cannot predict when such effects will subside. This may prevent the Company from being able to fulfill its customers’ orders in a timely manner or at all, which could lead to one or more of its customers cancelling their orders. At this time the Company is neither able to estimate the extent of these impacts nor predict whether its efforts to minimize or contain them will be successful. The Company intends to continue to monitor its business very closely for any effects of COVID-19 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, as discussed in Note 17, 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 and December 31, 2021, the Company’s cash and cash equivalents consisted of investments in money market mutual funds.

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

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

	March 31, 2022		March 31, 2021
Cash and cash equivalents	$	168,580	$	144,961
Restricted cash included in other assets		3,101		1,008
	$	171,681	$	145,969

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 and December 31, 2021 consisted of the following:

	March 31, 2022		December 31, 2021
Current portion of accounts receivable, net:
Accounts receivable, net	$	48,029	$	85,689
Accounts receivable, extended payment terms		77		85
		48,106		85,774
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 writes off accounts receivable against the provision when it determines a balance is uncollectible and no longer actively pursues collection of the receivable. Adjustments to the provision for doubtful accounts are recorded as selling, general and administrative expenses in the condensed consolidated statements of operations and comprehensive (loss) income.

As of March 31, 2022 and December 31, 2021, the Company concluded that all amounts due under extended payment terms were collectible and 0 reserve for credit losses was recorded. During the three months ended March 31, 2022 and 2021, the Company did 0t provide a reserve for credit losses and did 0t 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.

Impact of Recently Adopted Accounting Standards

In October 2021, the Financial Accounting Standards Board, 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, 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 after December 15, 2021, and interim periods within fiscal years beginning after December 15, 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 of Significant Accounting Policies” to the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

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.

8. Income Taxes

The Company’s effective income tax rate was (46.6)% and 28.8% for the three months ended March 31, 2022 and 2021, respectively. The provision for income taxes was $10,352 and $2,326 for the three months ended March 31, 2022 and 2021, respectively. The change in the provision for income taxes was primarily due to a new requirement to capitalize and amortize all research and experimentation expenditures for U.S. tax purposes, which became effective under the Tax Cuts and Jobs Act (“TCJA”) as of January 1, 2022. This new requirement results in significant forecasted U.S. income tax for the year and the corresponding deferred tax asset created is offset by a full valuation allowance. The change in the provision for income taxes was also impacted by changes in the jurisdictional mix of earnings period over period.

9. Debt

Term Loan and Revolving Credit Facilities

On December 20, 2016, the Company 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 providing for (i) a term loan facility of $300,000 (the “Term Loan”) and (ii) a revolving credit facility of up to $25,000 in revolving credit loans and letters of credit, which matured on December 20, 2021.

Current and non-current debt obligations reflected in the condensed consolidated balance sheets as of March 31, 2022 and December 31, 2021 consisted of the following:

Long-term debt, net of current portion and unamortized debt issuance costs	$	273,710		$	274,193

As of March 31, 2022, aggregate minimum future principal payments of the Company’s debt are summarized as follows:

Year Ending December 31,
Remainder of 2022	$	2,250
2023		275,225
Thereafter		—
	$	277,475

As of March 31, 2022 and December 31, 2021, $277,475 and $278,225 in principal amount, respectively, were outstanding under the Term Loan.

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%) 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 rate payable under the Term Loan is subject to an increase of 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, the interest rate on the Term Loans was 5.00% per annum, which was based on one-month Eurodollar rates, at the applicable floor of 1.00% 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, 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 during each of the three months ended March 31, 2022 and 2021 under the Term Loan. Interest expense for the Term Loan, including the amortization of debt issuance costs, totaled $3,777 and $3,869 for the three months ended March 31, 2022 and 2021, respectively.

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 Loan of $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% 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% 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% of the Company’s excess cash flow, as defined in the credit agreement, subject to reduction upon its 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 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, such as the Company’s ability to pay dividends, certain of which are based upon the Company’s total net leverage ratio. The Company was in compliance with all covenants as of March 31, 2022 and December 31, 2021.

11. Stock-based Compensation

2017 Stock Incentive Plan

The Company’s 2017 Stock Incentive Plan (the “2017 Plan”) provides for the Company to sell or issue common stock or restricted common stock, or to grant qualified incentive stock options, nonqualified stock options, SARs, performance-based restricted stock units (“PSUs”), RSUs or other stock-based awards to the Company’s employees, officers, directors, advisors and outside consultants. The total number of shares authorized for issuance under the 2017 Plan was 19,842 shares as of March 31, 2022, of which 9,650 shares remained available for future grant.

Stock Options

A summary of stock option activity for the three months ended March 31, 2022 is as follows:

	Number of Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term		Aggregate Intrinsic Value
						(in years)
Outstanding at January 1, 2022		5,919		$	8.82		4.36	$	4,205
Granted		576			4.31
Exercised		(33	)		2.36
Forfeited		(68	)		9.35
Outstanding at March 31, 2022		6,394		$	8.44		4.60	$	1,708
Options exercisable at March 31, 2022		5,586		$	8.94		3.89	$	1,557
Vested or expected to vest at March 31, 2022		6,324		$	8.48		4.54	$	1,695

The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model using the following assumptions:

	Three Months Ended March 31,
	2022	2021
Risk-free interest rate	1.7%–2.0%	0.4%
Expected term (in years)	6.1	6.1
Expected volatility	38.5%–38.7%	38.2%
Expected dividend yield	0.0%	0.0%

The weighted-average grant-date fair value of options granted during the three months ended March 31, 2022 and 2021 was $1.72 and $3.42 per share, respectively. Cash proceeds received upon the exercise of options were $79 and $574 during the three months ended March 31, 2022 and 2021, respectively. The intrinsic value of stock options exercised during the three months ended March 31, 2022 and 2021 was $76 and $805, 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.

Restricted Stock Units

A summary of RSU activity for the three months ended March 31, 2022 is as follows:

	Number of Shares			Weighted- Average Grant Date Fair Value		Aggregate Fair Value
Unvested balance at January 1, 2022		4,309		$	6.34

The Company withheld 318 and 593 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, 2022 and 2021, respectively.

Performance-Based Stock Units

During the three months ended March 31, 2021, 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 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 of Directors. Vesting may occur at any time during the three-year period.

Compensation expense is based on the estimated value of the awards on the grant date, and is recognized over the period from the grant date through the expected vest dates of each vesting condition, both of which were estimated based on a Monte Carlo simulation model applying the following key assumptions:

		Three Months Ended March 31,
		2021
Risk-free interest rate		0.2%
Volatility		78.6%
Dividend yield		0.0%
Cost of equity		12.0%

Costs to Obtain or Fulfill a Contract

As of March 31, 2022 and December 31, 2021, the Company had short-term capitalized contract costs of $124 and $90, respectively, which are included in prepaid expenses and other current assets and had long-term capitalized contract costs of $64 and $58, respectively, which are included in other assets in the accompanying condensed consolidated balance sheets. During the three months ended March 31, 2022 and 2021, amortization expense associated with capitalized contract costs was $29 and $23, respectively, which was recorded to selling, general and administrative expenses in the accompanying condensed consolidated statements of operations and comprehensive (loss) income.

Contract Balances

Contract liabilities consist of deferred revenue and include payments received in advance of performance under the contract. Such amounts are recognized as revenue when the Company satisfies its performance obligations, consistent with the above methodology. For the three months ended March 31, 2022, the Company recognized $5,636 of revenue that was included in deferred revenue 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 receives payments from customers based upon contractual billing terms. Accounts receivable are recorded when the right to consideration becomes unconditional. Contract assets include amounts related to the Company’s contractual right to consideration for both completed and partially completed performance obligations that may not have been invoiced. As of March 31, 2022 and December 31, 2021, the Company included contract assets of $409 and $95, respectively.

Transaction price allocated to the remaining performance obligations

As of March 31, 2022, the aggregate remaining amount of revenue expected to be recognized related to unsatisfied or partially unsatisfied performance obligations was $25,613, which consists of deferred revenue. The Company expects approximately 75% of this amount to be recognized in the next twelve months with the remaining amount to be recognized over the next two to five years.

Other Revenue Recognition Policies

The Company’s customary payment terms are generally 90 days or less. If the Company provides extended payment terms that represent a significant financing component, the Company adjusts the amount of promised consideration for the time value of money using an appropriate discount rate and recognizes interest income separate from the revenue recognized on contracts with customers. During the three months ended March 31, 2022 and 2021, the Company recorded interest income of $5 and $6, respectively, which was recorded in the condensed consolidated statements of operations and comprehensive (loss) income.

14. Segment Information

The Company operates as 1 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.

Casa China paid Rongke Xie $37 and $33 in total compensation during the three months ended March 31, 2022 and 2021, respectively, for her services as an employee.

To date, the Company has granted to Rongke Xie 116 RSUs which vest over four annual periods. The grant-date fair value of the awards totaled $500, which is recorded as stock-based compensation expense over the vesting period of the awards. During the three months ended March 31, 2022 and 2021, the Company recognized selling, general and administrative expenses of $31 and $25 related to these awards.

16. Commitments and Contingencies

Indemnification

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

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

As of March 31, 2022 and December 31, 2021, the Company had not experienced any material losses related to these indemnification obligations and 0 material claims were outstanding where a contingent loss was considered to be probable or reasonably estimable. The Company does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible, and no related liabilities were recorded in its condensed consolidated financial statements.

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

Overview

With our physical, virtual and cloud-native 5G infrastructure 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 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 solutions that can meet the evolving bandwidth needs of our customers and their subscribers. Our first installation in a service provider’s network frequently involves deploying our broadband products in only a portion of the provider’s network and, for our cable products, with only a fraction of the capacity of our products enabled at the time of initial installation. Over time, our customers have generally expanded the use of our solutions to other areas of their networks to extend network coverage or increase network capacity.

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

COVID-19 Pandemic

The ongoing COVID-19 pandemic presents various risks to us, which could continue to have a material effect upon the estimates and judgments relied upon by management in preparing these condensed consolidated financial statements. While we remain fully operational, during the three months ended March 31, 2022, the effects of the COVID-19 pandemic on the global supply chain had a significant adverse effect on our financial results. In particular, certain of our products utilize components whose availability was significantly exceeded by global demand. As a result, during the three months ended March 31, 2022, we continued to see shortages of supply that resulted in our inability to fulfill certain customer orders within normal lead times. This adversely impacted our revenue and operating results for the three months ended March 31, 2022. Additionally, shipping bottlenecks and delays further negatively affected our ability to timely fulfill customer orders, thereby delaying our ability to consummate sales and recognize revenue. We have also seen, in some cases, significant increases in shipping costs. While we continue to work with our supply chain, contract manufacturers, logistics partners and customers to minimize the extent of such impacts, we expect the effects of global supply chain issues to continue and cannot predict when such effects will subside. This may prevent us from being able to fulfill our customers’ orders in a timely manner or at all, which could lead to one or more of our customers cancelling their orders. At this time, we are neither able to estimate the extent of these impacts nor predict whether our efforts to minimize or contain them will be successful. We intend to continue to monitor our business very closely for any effects of COVID-19 for as long as necessary.

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, 2022 are not necessarily indicative of the results to be expected in future periods. Management cannot predict the full impact of the ongoing COVID-19 pandemic on our sales channels, supply chain, manufacturing and distribution, or on economic conditions generally, including the effects on our current and potential

customers, who may temporarily accelerate or curtail spending on investments in current and/or new technologies, delay new equipment evaluations and trials 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.

Total revenue	$	64,399	$	104,277	$	(39,878	)		(38.2	)%

Product revenues during the three months ended March 31, 2022 were adversely affected by supply chain delays across all of our markets. Wireless and cable revenues also decreased significantly due to decreased revenues from certain Tier 1 customers in the period, as well as timing of certain orders.

The increase in service revenue was primarily due to increased support renewals in the three months ended March 31, 2022 as compared to the three months ended March 31, 2021.

The increase in cost of product revenue and the decrease in gross margin was due to product mix, with a lower proportion of higher margin software product revenue in the three months ended March 31, 2022 as compared to the three months ended March 31, 2021.

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

Research and Development

	2022			2021			Amount		%

Research and development	$	22,673		$	21,606		$	1,067		4.9	%
Percentage of revenue		35.2	%		20.7	%

The increase in research and development expense was primarily due to a $1.8 million increase in personnel costs, driven by the impact of a reduction in payroll taxes due to a CARES Act credit of $1.3 million during the three months ended March 31, 2021, which did not repeat in 2022, increased salaries and bonus of $0.8 million due to increased headcount and annual salary increases in 2022, net of decreased stock-based compensation of $0.3 million. Partially offsetting this increase was a decrease in purchases of research and development materials of $0.5 million and a decrease in depreciation of $0.3 million during the three months ended March 31, 2022 as compared to the three months ended March 31, 2021.

Selling, General and Administrative

Selling, general and administrative	$	22,329		$	21,880		$	449		2.1	%
Percentage of revenue		34.7	%		21.0	%

The increase in selling, general and administrative expense was primarily due to an increase in personnel costs of $0.8 million, driven by the impact of a reduction in payroll taxes due to a CARES Act credit of $0.7 million during the three months ended March 31, 2021, which did not repeat in 2022, an increase of $0.2 million in travel expenses and increased commissions expense of $0.5 million, net of a decrease of $0.6 million in stock-based compensation expense. Trade show expense also increased $0.5 million during the three months ended March 31, 2022. These increases were partially offset by decreased depreciation expense of $0.2 million, decreased other taxes of $0.2 million and decreased professional fees of $0.3 million during the three months ended March 31, 2022 as compared to the three months ended March 31, 2021.

Other Income (Expense), Net

Other income (expense), net	$	(3,909	)	$	(4,479	)	$	570		(12.7	)%
Percentage of revenue		(6.1	)%		(4.3	)%

The change in other income (expense), net was primarily due to a $0.5 million decrease in foreign exchange losses attributable to fluctuations in the Australian dollar and the China Renminbi exchange rates. Interest expense also decreased $0.1 million due to lower overall debt balances in the three months ended March 31, 2022 as compared to the three months ended March 31, 2021.

Provision for Income Taxes

	Three Months Ended March 31,				Change
	2022		2021		Amount		%
	(dollars in thousands)
Provision for income taxes	$	10,352	$	2,326	$	8,026		345.1	%

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. The change in the provision for income taxes was also impacted by changes in the jurisdictional mix of earnings period over period.

Liquidity and Capital Resources

Our principal sources of liquidity have been and continue to be our cash and cash equivalents and cash flows from operations. The following tables set forth our cash and cash equivalents and working capital as of March 31, 2022 and December 31, 2021 and our cash flows for the three months ended March 31, 2022 and 2021:

	March 31, 2022		December 31, 2021
	(in thousands)
Consolidated Balance Sheet Data:
Cash and cash equivalents	$	168,580	$	154,703
Working capital		236,725		264,157

Net cash used in investing activities		(966	)		(2,252	)
Net cash used in financing activities		(3,354	)		(4,819	)

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

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

Investing Activities

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

Net cash used in investing activities during the three months ended March 31, 2022 was $1.0 million, consisting of purchases of property and equipment and software licenses.

Financing Activities

Net cash used in financing activities during the three months ended March 31, 2022 was $3.4 million, consisting primarily of employee taxes paid related to net share settlement of equity awards of $1.5 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 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 repurchases 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 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. 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.

Contractual Obligations and Commitments

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 and commitments from those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Critical Accounting Policies and Significant Judgments and Estimates

We prepare our condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States. The preparation of condensed consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by our management.

Other than our 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.

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

Changes in Internal Control over Financial Reporting

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

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

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

On May 29, 2019, John Shen filed a putative shareholder class action complaint in the Massachusetts Superior Court of Essex County, John Shen v. Casa Systems, Inc, et al., Civil Action No. 1977CV00787, against us; certain of our current and former executive officers and directors; Summit Partners, our largest investor; and the underwriters from our December 15, 2017, initial public offering, or IPO. On July 3, 2019, Mirza R. Baig filed a similar putative shareholder class action complaint in the Massachusetts Superior Court of Essex County, Mirza R. Baig v.

Casa Systems, Inc, et al., Civil Action No. 19-CV-03203-BLS2 and Mirza 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, or the 2021 10-K, which could materially affect our business, financial condition or future results. There have been no material changes from the risk factors previously disclosed in the 2021 10-K.

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, 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.
