1. Description of Business and Summary of Significant Accounting Policies
Description of Business

A10 Networks, Inc. (together with our subsidiaries, the “Company”, “we”, “our” or “us”) was incorporated in California in 2004 and reincorporated in Delaware in March 2014. We are headquartered in San Jose, California and have wholly-owned subsidiaries throughout the world including Asia and Europe.

We are a leading provider of secure application solutions and services that enable a new generation of intelligently connected companies with the ability to continuously improve cyber protection and digital responsiveness across dynamic Information Technology (“IT”) and network infrastructures. Our product portfolio seeks to address many of the cyber protection challenges and solution requirements. The portfolio consists of six secure application solutions; Thunder Application Delivery Controller (“ADC”), Lightning Application Delivery Controller (“Lightning ADC”), Thunder Carrier Grade Networking (“CGN”), Thunder Threat Protection System (“TPS”), Thunder SSL Insight (“SSLi”) and Thunder Convergent Firewall (“CFW”), and two intelligent management and automation tools; Harmony Controller and aGalaxy TPS. Our solutions are available in a variety of form factors, such as optimized hardware appliances, bare metal software, containerized software, virtual appliances and cloud-native software. Our customers include leading service providers (cloud, telecommunications, multiple system operators, cable), government organizations, and enterprises.

We derive revenue from two sources: (i) products revenue, which includes hardware, perpetual software license and subscription offerings, which include term-based license agreements and software-as-a-service; and (ii) services revenue, which includes post contract support (“PCS”), professional services, and training. Revenue for term-based license agreements is recognized at a point in time when the Company delivers the software license to the customer and the subscription term has commenced. For our software-as-a-service offerings, our customers do not take possession of the Company’s software but rather we provide access to the service via a hosting arrangement. Revenue in these arrangements is recognized ratably as the services are provided. A substantial portion of our revenue is from sales of our products and services through distribution channel partners, such as resellers and distributors. Our customers predominantly purchase PCS services in conjunction with purchases of our products. We recognize services revenue ratably over the term of the PCS contract, which is typically one year, but can be up to seven years.

We sell our products globally to service providers and enterprises that depend on data center applications and networks to generate revenue and manage operations efficiently. We report two customer verticals: service providers and enterprises and we report customer revenues in three broad geographic regions: the Americas, APJ and EMEA regions. In the three months ended March 31, 2022, we changed the way we present revenue by geographic region. The Americas region comprises the United States and all other countries in the Americas (excluding the United States). The APJ region comprises Japan and all other countries in APAC (excluding Japan). The EMEA region comprises Europe, Middle East and Africa. We believe this vertical and revised geographic view aligns with how we manage the business and maps our product portfolio to customer verticals. This change in the way we report revenue had no impact to our key metrics including operations, comprehensive income and accumulated deficit.

Our end-customers operate in a variety of industries, including telecommunications, technology, industrial, retail, financial, gaming, education and government. Since inception, our customer base has grown rapidly. As of March 31,June 30, 2023, we have sold our products to more than 8,1008,200 end-customers worldwide since our inception.

We sell substantially all of our solutions through our high-touch sales organization as well as distribution channel partners, including distributors, value-added resellers and system integrators, and fulfill nearly all orders globally through such partners. We believe this sales approach allows us to obtain the benefits of channel distribution, such as expanding our market coverage, while still maintaining face-to-face relationships with our end-customers. We outsource the manufacturing of our hardware products to original design manufacturers. We perform quality assurance and testing at our San Jose, Taiwan and Japan distribution centers, as well as at our manufacturers’ locations.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include those of A10 Networks, Inc. and its subsidiaries after elimination of all intercompany accounts and transactions.

We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC” or the “Commission”). As permitted under these rules and regulations, we have condensed or omitted certain financial information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with accounting principles generally accepted in
9


the United States of America (“U.S. GAAP”). The unaudited condensed consolidated balance sheet as of December 31,
10


2022 has been derived from our audited financial statements, which are included in our 2022 Annual Report on Form 10-K for the year ended December 31, 2022 on file with the SEC (the “2022 Annual Report”).

These financial statements have been prepared on the same basis as our annual financial statements and, in management’s opinion, reflect all adjustments consisting only of normal recurring adjustments that are necessary for a fair presentation of our financial information. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. 

These financial statements and accompanying notes should be read in conjunction with the financial statements and accompanying notes thereto in the 2022 Annual Report.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Those estimates and assumptions affect revenue recognition and deferred revenue, the allowance for doubtful accounts, the sales return reserve, the valuation of inventory, the fair value of marketable securities, contingencies and litigation, accrued liabilities, deferred commissions and the determination of fair value of stock-based compensation. These estimates are based on information available as of the date of the condensed consolidated financial statements.

Significant Accounting Policies

The Company’s significant accounting policies are disclosed in Part IIItem 8, “Financial Statements and Supplementary Data” of the 2022 Annual Report filed with the SEC on February 27, 2023. There have been no material changes to the Company’s significant accounting policies during the three and six months ended March 31,June 30, 2023.

Concentration of Credit Risk and Significant Customers

Financial instruments that potentially subject us to concentrations of credit risk consist of cash, cash equivalents, marketable securities and accounts receivable. Our cash, cash equivalents and marketable securities are held and invested in high-credit quality financial instruments by recognized financial institutions and are subject to minimum credit risk.

Our accounts receivable are unsecured and represent amounts due to us based on contractual obligations of our customers. We mitigate credit risk in respect to accounts receivable by performing periodic credit evaluations based on a number of factors, including past transaction experience, evaluation of credit history and review of the invoicing terms of the contract. We generally do not require our customers to provide collateral to support accounts receivable.

Significant customers, including distribution channel partners and direct customers (end-customers), are those which represent 10% or more of our total revenue for each period presented or our gross accounts receivable balance as of each respective balance sheet date.

Revenues from our significant customers as a percentage of our total revenue are as follows:
Three Months Ended March 31,Three Months Ended June 30,Six Months Ended June 30,
CustomersCustomers20232022Customers2023202220232022

Customer C (a distribution channel partner)19%11%
* represents less than 10% of total revenue
1011



As of March 31,June 30, 2023, one customer accounted for 31%33% of our total gross accounts receivable. As of December 31, 2022, two customers accounted for 21% each of our total gross accounts receivable.

Recently Adopted Accounting Pronouncements

The Company’s recently adopted accounting pronouncements are disclosed in Note 1 Description of Business and Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Part II – Item 8 of the 2022 Annual Report. The Company has not adopted any accounting pronouncements during the three and six months ended March 31,June 30, 2023.

5. Commitments and Contingencies

Lease Commitments

We lease various operating spaces in the United States, Asia and Europe under non-cancelable operating lease arrangements that expire on various dates through July 2027. These arrangements require us to pay certain operating expenses, such as taxes, repairs and insurance, and contain renewal and escalation clauses. We recognize rent expense under these arrangements on a straight-line basis over the term of the lease. See Note 2 – Leases for the Company’s aggregate future lease payments for the Company’s non-cancelable operating leases as of March 31,June 30, 2023.

Rent expense was $1.2 million and $1.3 million for both the three months ended March 31,June 30, 2023 and 2022, respectively, and was $2.5 million for both of the six months ended June 30, 2023 and 2022.

Purchase Commitments

We have open purchase commitments with third-party contract manufacturers with facilities in Taiwan to supply nearly all of our finished goods inventories, spare parts, and accessories. These purchase orders are expected to be paid within one year of the issuance date. We had open purchase commitments with manufacturers in Taiwan totaling $26.1$19.8 million as of March 31,June 30, 2023.

Guarantees and Indemnifications

In the normal course of business, we provide indemnifications to customers against claims of intellectual property infringement made by third parties arising from the use of our products. Other guarantees or indemnification arrangements include guarantees of product and service performance, and standby letters of credit for lease facilities and corporate credit cards. We have not recorded a liability related to these indemnification and guarantee provisions and our guarantees and indemnification arrangements have not had any significant impact on our condensed consolidated financial statements to date.

6. Equity Incentive Plans, Stock-Based Compensation and Stock Repurchase Program

Equity Incentive Plans

2014 Equity Incentive Plan and 2023 Stock Incentive Plan

The 2014 Equity Incentive Plan (the “2014 Plan”) providesprovided for the granting of stock options, restricted stock awards, restricted stock units (“RSUs”), performance-based RSUs (“PSUs”), stock appreciation rights, performance units and performance shares to our employees, consultants and members of our Board of Directors.

The shares authorized for the 2014 Plan increase annually by the lesser of (i) 8,000,000 shares, (ii) 5% of the outstanding shares of common stock on the last day of our immediately preceding fiscal year, or (iii) such other lesser amount as determined by our Board of Directors. Since November 2020, our Board of Directors determined the number of shares authorized under the 2014 Plan were sufficient for the time being and decided not to increase the number of shares authorized in 2021, 2022 and 2023. As of March 31, 2023, we had 12,793,083 shares available for future grant under the 2014 Plan.

On April 26, 2023, the Company’s stockholders approved the A10 Networks, Inc. 2023 Stock Incentive Plan (the “2023 Plan”), which was approved by the Company’s Board of Directors on March 10, 2023, pending stockholder approval.

7. Net Income Per Share

Basic net income per share is computed using the weighted average number of common shares outstanding for the period. Diluted net income per share applying the treasury stock method is computed using the weighted average number of common shares outstanding for the period plus potential dilutive common shares, including stock options, RSUs, PSUs and employee stock purchase rights, unless the potential common shares are anti-dilutive.

Basic and diluted net income per share are calculated as follows (in thousands, except per share amounts):

8. Income Taxes

We recorded an income tax expenseprovision of $1.0$3.2 million and income tax benefitfor both of $1.1 million for the three months ended March 31,June 30, 2023 and 2022, respectively. We recorded an income tax provision of $4.2 million and $4.4 million for the six months ended June 30, 2023 and 2022, respectively. The Company’s income tax provision for the three and six months ended March 31,June 30, 2023 and 2022 primarily consisted of U.S. federal and state taxes.

We had $7.1$7.2 million of unrecognized tax benefits as of March 31,June 30, 2023. We do not anticipate a material change to our unrecognized tax benefits over the next twelve months. Unrecognized tax benefits may change during the next twelve months for items that arise in the ordinary course of business.

Accrued interest and penalties related to unrecognized tax benefits are recognized as part of our provision for income taxes in our condensed consolidated statements of operations.

We are subject to taxation in the United States, various states, and several foreign jurisdictions. Because we have net operating loss and credit carryforwards, there are open statutes of limitations in which federal, state and foreign taxing authorities may examine our tax returns for all years from 2005 through the current period. We are not currently under examination by any taxing authorities.

On June 29, 2020, the California Governor signed Assembly Bill 85, which includes several tax measures, provides for a three-year suspension of the use of net operating losses for medium and large businesses and a three-year limit on the use of
1819


business incentive tax credits to offset no more than $5 million of tax per year. The three-year term was subsequently revised to a two-year term and has been accounted for in our income tax provision.

9. Geographic Information

We report customer revenues in three broad geographic regions: the Americas, APJ and EMEA regions. In the three months ended March 31, 2022, we changed the way we present revenue by geographic region. The Americas region comprises the United States and all other countries in the Americas (excluding the United States). The APJ region comprises Japan and all other countries in APAC (excluding Japan). We believe this vertical and revised geographic view aligns with how we manage the business and maps our product portfolio to customer verticals. This change in the way we report revenue had no impact to our key metrics including operations, comprehensive income and accumulated deficit.

The following table depicts the disaggregation of revenue by geographic region based on the ship to location of our customers and is consistent with how we evaluate our financial performance (in thousands):

Deferred revenue primarily consists of amounts that have been invoiced but not yet been recognized as revenue and consists of performance obligations pertaining to support and subscription services. We recognized revenue of $25.2$26.1 million and $24.6$19.6 million during the three months ended March 31,June 30, 2023 and 2022, respectively, related to deferred revenues at the beginning of the respective periods. We recognized revenue of $51.3 million and $44.2 million during the six months ended June 30, 2023 and 2022, respectively, related to deferred revenues at the beginning of the respective periods.
Deferred Contract Acquisition Costs
We capitalize certain contract acquisition costs consisting of incremental sales commissions incurred to obtain customer contracts. Deferred commissions related to product revenues are recognized upon transfer of control to customers. Deferred commissions related to services revenue are recognized as the related performance obligations are met. Deferred commissions that will be recognized during the succeeding 12-month period are recorded as prepaid expenses and other current assets, and the remaining portion is recorded as other non-current assets. Amortization of deferred commissions is included in sales and marketing expense.
As of March 31,June 30, 2023, the current and non-current portions of deferred contract acquisition costs were $6.1$6.2 million and $4.1 million, respectively. As of December 31, 2022, the current and non-current portions of deferred contract acquisition costs were $6.1 million and $4.3 million, respectively. Related amortization expense was $1.9$1.5 million and $2.0$2.1 million for the three months ended March 31,June 30, 2023 and 2022, respectively, and was $3.4 million and $4.2 million for the six months ended June 30, 2023 and 2022, respectively.

We had no impairment loss in relation to the costs capitalized and no asset impairment charges related to contract assets during the three and six months ended March 31,June 30, 2023 and 2022.

Remaining Performance Obligations
Remaining performance obligations represent contracted revenues that are non-cancellable and have not yet been recognized due to unsatisfied or partially satisfied performance obligations, which include deferred revenues and amounts that will be invoiced and recognized as revenues in future periods.
We expect to recognize revenue on the remaining performance obligations as follows (in thousands):

ITEM 2.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations (“MD&A”) should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this document. In addition to historical information, the MD&A contains forward-looking statements that reflect our plans, estimates, and beliefs that involve significant risks and uncertainties. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to those differences include those discussed below and elsewhere in this Quarterly Report on Form 10-Q, particularly in “Note Regarding Forward-Looking Statements” and other risk factors contained in Part I, Item 1A “Risk Factors” in our 2022 Annual Report.

Overview

We are a leading provider of secure application solutions and services that enable a new generation of intelligently connected companies with the ability to continuously improve cyber protection and digital responsiveness across dynamic Information Technology (“IT”) and network infrastructures. Our product portfolio seeks to address many of the cyber protection challenges and solution requirements. The portfolio consists of six secure application solutions; Thunder Application Delivery Controller (“ADC”), Lightning Application Delivery Controller (“Lightning ADC”), Thunder Carrier Grade Networking (“CGN”), Thunder Threat Protection System (“TPS”), Thunder SSL Insight (“SSLi”) and Thunder Convergent Firewall (“CFW”), and two intelligent management and automation tools; Harmony Controller and aGalaxy TPS. Our solutions are available in a variety of form factors, such as optimized hardware appliances, bare metal software, containerized software, virtual appliances and cloud-native software. Our customers include leading service providers (cloud, telecommunications, multiple system operators, cable), government organizations, and enterprises.

We derive revenue from two sources: (i) products revenue, which includes hardware, perpetual software license and subscription offerings, which include term-based license agreements and software-as-a-service; and (ii) services revenue, which includes post contract support (“PCS”), professional services, and training. Revenue for term-based license agreements is recognized at a point in time when the Company delivers the software license to the customer and the subscription term has commenced. For our software-as-a-service offerings, our customers do not take possession of the Company’s software but rather we provide access to the service via a hosting arrangement. Revenue in these arrangements is recognized ratably as the services are provided. A substantial portion of our revenue is from sales of our products and services through distribution channel partners, such as resellers and distributors. Our customers predominantly purchase PCS services in conjunction with purchases of our products.

We sell our products globally to service providers and enterprises that depend on data center applications and networks to generate revenue and manage operations efficiently. We report two customer verticals: service providers and enterprises and we report customer revenues in three broad geographic regions: the Americas, APJ and EMEA regions. In the three months ended March 31, 2022, we changed the way we present revenue by geographic region. The Americas region comprises the United States and all other countries in the Americas (excluding the United States). The APJ region comprises Japan and all other countries in APAC (excluding Japan). The EMEA region comprises Europe, Middle East and Africa. We believe this vertical and revised geographic view aligns with how we manage the business and maps our product portfolio to customer verticals. This change in the way we report revenue had no impact to our key metrics including operations, comprehensive income and accumulated deficit.

Our end-customers operate in a variety of industries, including telecommunications, technology, industrial, retail, financial, gaming, education and government. Since inception, our customer base has grown rapidly. As of March 31,June 30, 2023, we have sold our products to more than 8,1008,200 customers worldwide since our inception.

We sell substantially all of our solutions through our high-touch sales organization as well as distribution channel partners, including distributors, value-added resellers and system integrators, and fulfill nearly all orders globally through such partners. We believe this sales approach allows us to obtain the benefits of channel distribution, such as expanding our market coverage, while still maintaining face-to-face relationships with our end-customers. We outsource the manufacturing of our hardware products to original design manufacturers. We perform quality assurance and testing at our San Jose, Taiwan and Japan distribution centers, as well as at our manufacturers’ locations.

During the three months ended March 31,June 30, 2023, (i) 52%56% of our total revenue was generated from the Americas region, of which 42%48% was generated from the United States, (ii) 27%33% from the APJ region, of which 18%19% was generated from Japan, and (iii) 21%11% from the EMEA region. During the three months ended March 31,June 30, 2022, (i) 53%57% of our total revenue was generated from the Americas region, of which 47%50% was generated from the United States, (ii) 28%32% from the APJ region, of which 18%20% was generated from Japan, and (iii) 19%11% from the EMEA region. One of our priorities is to strengthen our sales efforts in North America. Our enterprise customers accounted for 44%33% and 35% of our total revenue during the three months ended March 31,June 30, 2023 and 2022, respectively, and our service provider customers accounted for 56%67% and 65% of our total revenue during the three months ended March 31,June 30, 2023 and 2022, respectively.

As a result of the nature of our target market and the current stage of our development, a substantial portion of our revenue comes from a limited number of large customers, including service providers and enterprise customers, in any period. Purchases by our ten largest end-customers accounted for 33%51% and 45%49% of our total revenue for the three months ended March 31,June 30, 2023 and 2022, respectively. Sales to these large end-customers have typically been characterized by large but irregular purchases with long sales cycles. The timing of these purchases and the delivery of the purchased products are difficult to predict. Consequently, any acceleration or delay in anticipated product purchases by or deliveries to our largest customers could materially impact our revenue and operating results in any quarterly period. This may cause our quarterly revenue and operating results to fluctuate from quarter to quarter and make them difficult to predict.

As of March 31,June 30, 2023, we had $68.5$111.2 million of cash and cash equivalents and $76.0$42.7 million of marketable securities. Cash used inprovided by operating activities was $0.8$18.7 million during the threesix months ended March 31,June 30, 2023, compared to $15.9$24.7 million of cash provided by operating activities in the same period of 2022.

We intend to continue to invest for long-term growth. We have invested and expect to continue to invest in our product development efforts to deliver new products and additional features in our current products to address customer needs. In addition, we may expand our global sales and marketing organizations, expand our distribution channel partner programs and increase awareness of our solutions on a global basis. Our investments in growth in these areas may affect our short-term profitability.

Revenue

We derive revenue from two sources: (i) products revenue, which includes hardware, perpetual software license and subscription offerings, which include term-based license agreements and software-as-a-service; and (ii) services revenue, which includes post contract support (“PCS”), professional services, and training.

Our products revenue primarily consists of revenue from sales of our hardware appliances upon which our software is installed. Such software includes our ACOS software platform plus one or more of our ADC, CGN, TPS, SSLi or CFW solutions. Purchase of a hardware appliance includes a perpetual license to the included software. Additionally, an immaterial portion of our products revenue comes from subscription revenue. We offer several products by subscription, primarily through either term-based license agreements or as a service through our cloud-based platform. With respect to sales of our hardware appliances, we recognize products revenue upon transfer of control, generally at the time of shipment, provided that all other revenue recognition criteria have been met. Revenue for term-based license agreements is recognized at a point in time when we deliver the software license to the customer and the subscription term has commenced. For our software-as-a-service offerings, our customers do not take possession of our software but rather we provide access to the service via a hosting arrangement. Revenue in these arrangements is recognized ratably as the services are provided. As a percentage of revenue, our products revenue may vary from quarter to quarter based on, among other things, the timing of orders and delivery of products,
23


cyclicality and seasonality, changes in currency exchange rates and the impact of significant transactions with unique terms and conditions.

We generate services revenue from sales of post contract support (“PCS”), which is bundled with sales of products and technical services. We offer tiered PCS services under renewable, fee-based PCS contracts, primarily including technical
25


support, hardware repair and replacement parts, and software upgrades on a when-and-if-available basis. We recognize services revenue ratably over the term of the PCS contract, which is typically one year, but can be up to seven years.

A summary of our total revenue is as follows (dollars in thousands):

We currently do not have any plans to repatriate our earnings from our foreign operations. As of March 31,June 30, 2023, we had working capital of $141.9$149.4 million, accumulated deficit of $126.5$114.9 million and total stockholders’ equity of $185.5$192.9 million. Our marketable securities are highly liquid and are classified as available for sale should the Company decide to quickly raise cash at any time in the future.

30


We plan to continue to invest for long-term growth, and our investment may increase. We believe that our existing cash and cash equivalents and marketable securities will be sufficient to meet our anticipated cash needs for at least the next 12 months and beyond. Our future capital requirements will depend on many factors, including our growth rate, the expansion of sales and marketing activities, the timing and extent of spending to support development efforts, the introduction of new and enhanced product and service offerings and the continuing market acceptance of our products. In the event that additional financing is required from outside sources, we may not be able to raise such financing on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, operating results and financial condition could be adversely affected.

On October 28, 2021, the Company announced its Board of Directors authorized a stock repurchase program of up to $100 million of its common stock over a period of twelve months (the “2021 Program”). During the three months ended

March 31, June 30, 2022, the Company repurchased 2.1247.9 thousand shares for a total cost of $3.4 million under the 2021 Program. During the six months ended June 30, 2022, the company repurchased 2.4 million shares for a total cost of $28.3 million under the 2021 Program.$31.8 million. This repurchase program was active for twelve months and expired in the second half of 2022.

On November 1, 2022, the Company announced its Board of Directors authorized a new stock repurchase program (the “2022 Program”) of up to $50 million of its common stock over a period of twelve months. During the three and six months ended June 30, 2023, the Company repurchased 0.4 million shares for a total cost of $6.2 million. Under all programs, repurchased shares are held in treasury at cost. The Company’s stock repurchase programs do not obligate us to acquire any specific number of shares. Shares may be repurchased in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Exchange Act. Through March 31, 2023, no shares had been repurchased under the 2022 Program.

In October 2021, our Board approved the initiation of a regular quarterly cash dividend on our common stock. In the three months ended March 31,June 30, 2022, the Company paid a cash dividend of $0.05 per share outstanding, for a total of $3.9$3.8 million as a return of capital. In the three months ended March 31,June 30, 2023, the Company paid a cash dividend of $0.06 per share outstanding, for a total of $4.4 million as a return of capital. The next dividend, in the amount of $0.06 per share, will be paid on JuneSeptember 1, 2023 to stockholders of record on MayAugust 15, 2023 as a return of capital. We currently anticipate that we will continue to pay comparable quarterly cash dividends in the future. However, the payment, amount and timing of future dividends remain within the discretion of our Board and will depend upon our results of operations, financial condition, cash requirements, and other factors.

As described in Part II – Item 1, “Legal Proceedings” of this Quarterly Report on Form 10-Q, from time to time we are involved in ongoing litigation. Any adverse settlements or judgments in any litigation could have a material adverse impact on our results of operations, cash balances and cash flows in the period in which such events occur.

Cash Flows from Operating Activities

Our cash provided by operating activities is driven primarily by sales of our products and management of working capital investments. Our primary uses of cash from operating activities have been for personnel-related expenditures, manufacturing costs, marketing and promotional expenses and costs related to our facilities. Our cash flows from operating activities will continue to be affected principally by the extent to which we increase spending on our business and our working capital requirements.

During the threesix months ended March 31,June 30, 2023, cash used inprovided by operating activities was $0.8$18.7 million, consisting of net income of $4.0$15.6 million and non-cash charges of $5.7$11.3 million, partially offset by a decrease in cash resulting from the net

change in operating assets and liabilities of $10.5$8.1 million. Our non-cash charges consisted primarily of depreciation and amortization expenses of $2.1$4.3 million and stock-based compensation expense of $3.7$7.2 million. The net change in our operating assets and liabilities primarily reflects cash outflows from the changes in accrued liabilities of $17.0$17.1 million, inventory of $1.5$1.7 million and accounts payable of $0.7$1.5 million, partially offset by cash inflows from changes in accounts receivable of $5.7 million, prepaid expense and other assets of $1.5$3.8 million, accounts receivable of $3.7 million and deferred revenue of $1.5$4.6 million.

The unfavorable change in accrued liabilities was attributed to cash bonus and commission accruals. The unfavorable change in inventory was attributable to product shipments made in the threesix months ended March 31,June 30, 2023. The unfavorable change in accounts payable was attributable to the timing of payments to vendors. The favorable change in accounts receivable was attributed to timing of billing and cash collections. The favorable change in prepaid expenses and other assets was primarily due to the release and return of a security deposit. The favorable change in deferred revenue was attributable to the timing of service contract bookings.

Our operating lease arrangements expire on various dates through July 2027. These arrangements require us to pay certain operating expenses, such as taxes, repairs and insurance, and contain renewal and escalation clauses.

The Company also has $7.1$7.2 million of tax liabilities related to uncertain tax positions as of March 31,June 30, 2023. We are unable to make a reasonably reliable estimate of the timing of settlement, if any, of these future payments.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.

The Company’s significant accounting policies are disclosed in Part II – Item 8, “Financial Statements and Supplementary Data” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 27, 2023. There have been no material changes to the Company’s significant accounting policies during the threesix months ended March 31,June 30, 2023.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Foreign Currency Risk

Our condensed consolidated results of operations, financial position and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. Historically, the majority of our revenue contracts are denominated in U.S. Dollars, with the most significant exception being Japan where we invoice primarily in Japanese Yen. Our costs and expenses are generally denominated in the currencies where our operations are located, which is primarily in the Americas, EMEA and, to a lesser extent, Japan and the Asia Pacific region. We have a hedging program with respect to foreign currency risk. Revenue resulting from selling in local currencies and costs and expenses incurred in local currencies are exposed to foreign currency exchange rate fluctuations, which can affect our revenue and operating income. As exchange rates vary, operating income may differ from expectations.

The functional currency of our foreign subsidiaries is the U.S. Dollar. At the end of each reporting period, monetary assets and liabilities are remeasured to the functional currency using exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are remeasured at historical exchange rates. Gains and losses related to remeasurement are recorded in interest and other income, net in the condensed consolidated statements of operations. A significant fluctuation in the exchange rates between our subsidiaries’ local currencies, especially the Japanese Yen, British Pound and Euro, and the U.S. Dollar could have an adverse impact on our condensed consolidated financial position and results of operations.

We recorded $2.2 million and $0.6$0.4 million of net foreign exchange gains during the three months ended June 30, 2023 and 2022, respectively, and we recorded $0.1 million and $0.2 million of net foreign exchange losses during the threesix months ended March 31,June 30, 2023, and 2022, respectively. The effect of a hypothetical 10% change in our exchange rate would not have a significant impact on our condensed consolidated results of operations.

Interest Rate Sensitivity

Our exposure to market risk for changes in interest rates relates primarily to our marketable securities. Our marketable securities are comprised of corporate securities, U.S. Treasury and agency securities, commercial paper and asset-backed securities. We do not enter into investments for trading or speculative purposes. As of March 31,June 30, 2023, our investment portfolio included marketable securities with an aggregate amortized cost basis of $76.4$42.8 million and a fair value of $76.0$42.7 million. The effect of a hypothetical 10% change in interest rates would not have had a material impact on our interest expense.

The following table presents the hypothetical fair values of our marketable securities assuming immediate parallel shifts in the yield curve of 50 basis points (“BPS”), 100 BPS and 150 BPS as of March 31,June 30, 2023 (in thousands):

ITEM 4. CONTROLS AND PROCEDURES

33


Management’s Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer), has evaluated the effectiveness of our disclosure controls and procedures as of March 31,June 30, 2023, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934, or the Exchange Act. 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 the company in the reports that it files or submits to the SEC, under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’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 the company’s management, including its principal executive and financial officers, as appropriate to enable timely decisions regarding required disclosure.

30


In designing and evaluating our disclosure controls and procedures, our management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that our management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Our Chief Executive Officer and Chief Financial Officer, as our principal executive officer and principal financial officer, respectively, concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31,June 30, 2023, and that the condensed consolidated financial statements included in this Form 10-Q present fairly, in all material respects, and in conformity with U.S. GAAP, our financial position, results of operations and cash flows for the periods presented.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the three months ended March 31,June 30, 2023, which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and our principal financial officer, does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well-designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We have been and may currently be involved in various legal proceedings, the outcomes of which are not within our complete control or may not be known for prolonged periods of time. Management is required to assess the probability of loss and amount of such loss, if any, in preparing our condensed consolidated financial statements. We evaluate the likelihood of a potential loss from legal proceedings to which we are a party. We record a liability for such claims when a loss is deemed probable and the amount can be reasonably estimated. Significant judgment may be required in the determination of both probability and whether an exposure is reasonably estimable. Our judgments are subjective based on the status of the legal proceedings, the merits of our defenses and consultation with in-house and outside legal counsel. As additional information becomes available, we reassess the potential liability related to pending claims and may revise our estimates. Due to the inherent uncertainties of the legal processes in the multiple jurisdictions in which we operate, our judgments may be materially different than the actual outcomes, which could have material adverse effects on our business, financial conditions and results of operations.

ITEM 1A. RISK FACTORS
Investing in our common stock involves a high degree of risk. You should carefully review and consider the information regarding certain factors that could materially affect our business, financial condition or future results set forth under Part I, Item 1A "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2022. There have been no material changes to the risk factors disclosed in our 2022 Annual Report on Form 10-K.


ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On November 1, 2022, we announced that our Board of Directors authorized a new $50 million share repurchase program (the “2022 Program”) under which we may repurchase up to $50 million of our outstanding common stock during the next 12 months. Under the share repurchase program, we may repurchase shares of common stock in the open market, privately negotiated transactions, in block trades or a combination of the foregoing. We are not obligated under the share repurchase program to repurchase any specific number or dollar amount of shares of common stock, and we may modify, suspend or discontinue the share repurchase program at any time. Our management and Board will determine the timing and amount of any repurchase in its discretion based on a variety of factors, such as the market price of our common stock, corporate requirements, general market economic conditions and legal requirements. The Company plans to fund repurchases from its existing cash balance and cash provided by operating activities. Through March 31, 2023, no shares had been repurchased under the 2022 Program.

Share repurchase activity during the three months ended June 30, 2023 was as follows (in thousands, except per share amounts):
PeriodsTotal Number of Shares PurchasedAverage Price Paid Per ShareTotal Number of Shares Purchased as Part of Publicly Announced Plans or ProgramsApproximate Dollar Value of Shares That May Yet Be Purchased Under the Plans or Programs (1)

(1) The $43,770 thousand in the table above represents the amount available to repurchase shares under the authorized repurchase program as of June 30, 2022. The Company’s active stock repurchase program (the “2022 Program”) does not obligate it to acquire any specific number of shares. Under the 2022 Program, shares may be repurchased in privately negotiated and/or open market transactions.
