These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including those described in "Risk Factors" and elsewhere in our Annual Report on Form 10-K filed with the United States Securities and Exchange Commission (the "SEC") on February 25, 2026. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following: execution risks related to closing key deals and improving our execution; the continued market adoption of our products; our ability to successfully anticipate market needs and opportunities; our timely development of new products and features; our ability to maintain profitability; any loss or delay of expected purchases by our largest end-customers, or the loss of, or reduction in orders from, significant customers or distribution channel partners on whom we depend for a substantial portion of our revenue; our ability to maintain or improve our competitive position; competitive and execution risks related to cloud-based computing trends and our ability to compete effectively in the market for AI-driven network solutions; our ability to attract and retain new end-customers and our largest end-consumers; our ability to maintain and enhance our brand and reputation; changes demanded by our customers in the deployment and payment model for our products; continued growth in markets relating to networking and network security; the success of any future acquisitions or investments in complementary companies, products, services or technologies; the ability of our sales and other teams to execute well; our ability to shorten our close cycles; the ability of our channels to sell our products; variations in product mix or geographic locations of our sales; risks associated with our presence in international markets; including changes in tariffs, trade policies, import/export restrictions, and countermeasures that may impact our costs, supply chain, or customer demand; risks related to our convertible notes, including interest expense obligations, potential dilution upon conversion, and liquidity requirements in the event of a fundamental change; cybersecurity threats, security breaches, or other vulnerabilities affecting our own systems, products, or services; our ability to attract, retain, and motivate qualified personnel, including key technical,

------

sales, and management employees; changes in tax laws and regulations, including ongoing assessment of the impact of OBBBA on our financial results; any unforeseen need for capital which may require us to divert funds we may have otherwise used for the dividend program or stock repurchase program; a significant decline in global macroeconomic or political conditions that have an adverse impact on our business and financial results; business interruptions related to our supply chain, including risks associated with the geographic concentration of our manufacturing operations in Taiwan and potential geopolitical instability affecting the region; our ability to manage our business and expenses if customers cancel or delay orders; weaknesses or deficiencies in our internal control over financial reporting; and our ability to timely file periodic reports required to be filed under the Securities Exchange Act of 1934, as well as other risks identified in the "Risk Factors" section contained in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2025.

In light of these risks, uncertainties, and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Any forward-looking statements made by us in this report speak only as of the date of this report, and we do not intend to update these forward-looking statements after the filing of this report, except as required by law.

We use our investor relations website, our company blog (https://www.a10networks.com/blog) and our corporate X (formerly Twitter) account (https://x.com/A10Networks) to post important information for investors, including news releases, analyst presentations, and supplemental financial information, and as a means of disclosing material non-public information and for complying with our disclosure obligations under Regulation FD. Accordingly, investors should monitor our investor relations website, our company blog and our corporate X account, in addition to following press releases, SEC filings and public conference calls and webcasts. We also make available, free of charge, on our investor relations website under "SEC Filings," our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to these reports as soon as reasonably practicable after electronically filing or furnishing those reports to the SEC.

**A10 Networks, Inc.** 

**Notes to Condensed Consolidated Financial Statements**

**(unaudited)**

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

***Description of Business***

A10 Networks, Inc. (together with our subsidiaries, the "Company", "A10", "we", "our" or "us") is a global provider of secure application and network solutions that protect, optimize, and scale business-critical systems across on-premises, hybrid cloud, and edge environments. Our network infrastructure and security products are designed to enable large enterprises, service providers, and cloud platforms worldwide to deliver performance, reliability, and protection against cyber threats, while preparing their networks for the demands of artificial intelligence ("AI") and next-generation applications.

We sell our solutions globally to service providers and enterprises who are looking to modernize and secure their digital infrastructure and application. Our service provider customers rely on scalable, efficient, and secure networks to deliver connectivity, cloud and other services that may generate revenue to their customers. Our enterprise customers require secure application delivery, AI-ready infrastructure, and are increasingly concerned about the landscape of cybersecurity threats across their complex networks and emerging AI workloads. 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 significantly.

A10's portfolio brings together secure application delivery, DDoS and API protection, and unified management into a cohesive platform that integrates with existing network architectures and leading public cloud environments. We deliver these capabilities through flexible deployment models, including software, cloud-native, and hardware form factors that are tailored to the scale and requirements of our customers. We generate revenue primarily from the sale of our secure networking and cybersecurity solutions and related support services. These offerings are delivered through a combination of direct and channel-based sales, with most customers purchasing maintenance and support alongside their initial deployment and renewing that support as contracts expire.

We derive revenue from two sources: (i) products revenue, which includes hardware, perpetual software licenses and subscription offerings, which include term-based license agreements; and (ii) services revenue, which includes post contract support ("PCS"), professional services, training and software-as-a-service ("SaaS") offerings. Revenue for term-based license agreements is recognized at a point in time when the Company delivers the software license to the customer and over time once the subscription term has commenced. For our SaaS 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 over time as the services are provided. A substantial portion of our revenue is from sales of our products and services through distribution channels, such as resellers and distributors. Our customers predominantly purchase PCS services in conjunction with purchases of our products.

We operate worldwide across the Americas, EMEA, and Asia Pacific, supported by a hybrid go-to-market model that combines a direct, high-touch sales organization with a broad ecosystem of distributors, resellers, and system integrators. 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.

We sell our products globally to enterprises and service providers that depend on data center applications and networks to generate revenue and manage operations efficiently. We report two customer verticals: enterprises, which accounted for 56% and 41% of our total revenue during the three months ended March 31, 2026 and 2025, respectively, and service providers, which accounted for 44% and 59% of our total revenue during the three months ended March 31, 2026 and 2025, respectively. While we expect total demand to remain strong as the need for cybersecurity solutions continues to increase, we expect the demand shift trend from service provider to enterprise to continue in the near term. We report customer revenues in three broad geographic regions: the Americas, APJ and EMEA regions. The Americas region comprises the U.S. and all other countries in the Americas (excluding the U.S.). The APJ region comprises Asia Pacific region including Japan. The EMEA region comprises Europe, Middle East and Africa. We believe this vertical and geographic view aligns with how we manage the business and maps our product portfolio to customer verticals.

We continue to invest in innovation that strengthens our leadership in secure infrastructure, expands our cybersecurity capabilities, and positions A10 at the intersection of network performance, protection, and AI-driven workloads. Our strategy is grounded in disciplined capital allocation and a commitment to deliver durable revenue growth, expanding recurring revenue, and strong cash flow generation.

***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"). 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 the United States of America ("U.S. GAAP"). The unaudited condensed consolidated balance sheet as of December 31, 2025 has been derived from our audited financial statements, which are included in our 2025 Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on February 25, 2026 (the "2025 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 2025 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 credit losses for potential uncollectible amounts, the sales return reserve, the valuation of inventory, the fair value of marketable securities, contingencies and litigation, accrued liabilities, deferred commissions, ThreatX Protect purchase price allocation 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, therefore, actual results could differ from management's estimates.

***Significant Accounting Policies***

The Company's significant accounting policies are disclosed in Part II – Item 8, "Financial Statements and Supplementary Data" of the 2025 Annual Report. There have been no material changes to the Company's significant accounting policies during the three months ended March 31, 2026.

***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 channels 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.

A substantial portion of our revenue is from sales of our products and services through distribution channels, such as resellers and distributors. In the three months ended March 31, 2026 and 2025, sales through a single distribution channel partner represented 38% and 17% of our total revenue, respectively.

------

Revenues from our significant end-customers as a percentage of our total revenue are as follows:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
|<br>**Customers** | **2026** | **2025** |
| Customer A | 37% | 15% |

---

We report revenue in two customer verticals: service providers, which accounted for 44% and 59% of our total revenue during the three months ended March 31, 2026 and 2025, respectively, and enterprises, which accounted for 56% and 41% of our total revenue during three months ended March 31, 2026 and 2025, respectively.

A substantial portion of our revenue comes from a limited number of large end-customers and service providers. Purchases from our ten largest end-customers accounted for 55% and 44% of our total revenue for three months ended March 31, 2026 and 2025, respectively.

As of March 31, 2026, a single distribution channel accounted for 40% of our total gross accounts receivable. As of December 31, 2025, a single distribution channel accounted for 23% of our total gross accounts receivable.

***Recent Accounting Standards Not Yet Adopted***

In November 2024, the FASB issued ASU 2024-03, *Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses*, requiring public entities to disclose additional information about specific expense categories in the notes to the consolidated financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

There have been no other recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the three months ended March 31, 2026 that are of significance or potential significance to us.

**4. Derivatives**

*Foreign Exchange Forward Contracts*

The Company uses derivative financial instruments to manage exposures to foreign currency that may or may not be designated as hedging instruments. The Company's objective for holding derivatives is to use the most effective methods to minimize the impact of these exposures. The Company does not enter into derivatives for speculative or trading purposes. The Company enters into foreign exchange forward contracts primarily to mitigate the effect of gains and losses generated by foreign currency transactions related to certain operating expenses and remeasurement of certain assets and liabilities denominated in foreign currencies.

For foreign exchange forward contracts not designated as hedging instruments, the fair value of the derivatives in a net gain or net loss position are recorded in prepaid expenses and other current assets in the accompanying condensed consolidated balance sheets. Changes in the fair value of derivatives are recorded in other income, net in the accompanying condensed consolidated statements of operations. As of March 31, 2026 and December 31, 2025, foreign exchange forward currency contracts not designated as hedging instruments had total notional amounts of $4.9 million and $2.0 million, respectively. These contracts have maturities of approximately 30 days. For the three months ended March 31, 2026 and 2025, the Company recorded an unrealized net losses of $52 thousand and $24 thousand, respectively, in its condensed consolidated statements of operations related to these contracts. For the three months ended March 31, 2026 and 2025, the Company recorded a realized net gain of $0.2 million and a realized net loss of $0.5 million, respectively, in its condensed consolidated statements of operations related to these contracts.

For foreign exchange forward contracts designated as hedging instruments, unrealized gains and losses arising from these contracts are recorded as a component of accumulated other comprehensive income (loss) on the consolidated balance sheets. These hedging contracts have 30 day maturities. The hedging gains and losses in accumulated other comprehensive income (loss) in the consolidated balance sheet are subsequently reclassified to expenses, as applicable, in the consolidated statements of operations in the same period in which the underlying transactions affect the Company's earnings. As of March 31, 2026 and December 31, 2025, the Company had no outstanding foreign exchange forward contracts designated as hedging instruments.

**5. Acquisition**

***ThreatX Protect Business***

In February 2025, we completed an acquisition of the ThreatX Protect business of ThreatX, Inc. for $19.1 million in cash. This acquisition has been accounted for as a business combination. The preliminary purchase price allocation is as follows: $7.6 million to identified intangible assets, $2.5 million to deferred revenue assumed and $0.2 million to net assets acquired, with the excess $13.8 million of the preliminary purchase price over the fair value of net assets acquired recorded as goodwill, allocated to our single operating segment. Goodwill is primarily attributable to assembled workforce, future synergies, and other intangible assets that do not qualify for separate recognition. Goodwill is not deductible for tax purposes.

The results of operations of the acquired business, which are not material, have been included in our condensed consolidated financial statements from the date of the acquisition. Pro forma results of operations have not been presented because the effect of the acquisition was not material to the condensed consolidated statements of operations.

The Company incurred approximately $0.3 million of acquisition-related costs, including legal, accounting, and advisory fees. These costs were expensed as incurred and included in general and administrative expenses in the condensed consolidated statements of operations. The cash outflows for these costs are classified as operating activities in the condensed consolidated statements of cash flows.

**7. Long-Term Debt** 

*2030 Convertible Senior Notes*

In March 2025, the Company issued $225.0 million aggregate principal amount of 2.75% Convertible Senior Notes due 2030 (the "2030 Notes"). The Company received net proceeds from the offering of approximately $217.7 million. The 2030 Notes will mature on April 1, 2030, unless earlier converted, redeemed or repurchased.

The 2030 Notes bear interest at the stated rate of 2.75% per annum, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on October 1, 2025. The 2030 Notes are convertible into solely cash, or a combination of cash and shares of common stock, at the Company's election, at an initial conversion rate of 42.6257 shares of common stock per $1,000 principal amount of 2030 Notes, which is equivalent to an initial conversion price of $23.46003 per share of common stock. The conversion rate is subject to customary adjustments for certain events as described in the indenture governing the 2030 Notes (the "2030 Notes Indenture"). Special interest and additional interest will accrue on the 2030 Notes in the circumstances and at the rates described in the 2030 Notes Indenture. The debt issuance costs are amortized to interest expense applying the effective interest method. The 2030 Notes do not contain financial maintenance covenants.

The holders may convert their 2030 Notes at their option only in the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ended on June 30, 2025, if the last reported sale price per share of the Company's

------

common stock exceeds 130% of the conversion price for each of at least 20 trading days during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during five consecutive business days immediately after any ten consecutive trading day period (such ten consecutive trading day period, the "measurement period") in which the trading price per $1,000 principal amount of 2030 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of Company's common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company's common stock, as described in the 2030 Notes Indenture; (4) if the Company calls such 2030 Notes for redemption; and (5) at any time from, and including, December 1, 2029 until the close of business on the 2nd scheduled trading day immediately before the maturity date.

If the Company undergoes a fundamental change (as defined in the 2030 Notes Indenture), subject to certain conditions, holders may require the Company to repurchase for cash all or any portion of their 2030 Notes, at a fundamental change repurchase price equal to 100% of the principal amount of the 2030 Notes to be repurchased, plus any accrued and unpaid special interest and additional interest, if any, up to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events or if the Company issues a notice of redemption, it will, under certain circumstances, increase the conversion rate for holders who elect to convert their 2030 Notes in connection with such corporate event or during the relevant redemption period.

The 2030 Notes are redeemable, in whole or in part (subject to certain limitations), for cash at Company's option at any time, and from time to time, on or after April 5, 2028 and on or before the 60th scheduled trading day immediately before the maturity date, but only if (i) the 2030 Notes are "freely tradable" (as defined in the 2030 Notes Indenture) and all accrued and unpaid additional interest, if any, has been paid in full; and (ii) the last reported sale price per share of common stock is at least 130% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the 2030 Notes to be redeemed, plus accrued and unpaid special and additional interest, if any, to, but excluding, the redemption date.

The 2030 Notes have customary provisions relating to the occurrence of "events of default" (as defined in the 2030 Notes Indenture). The occurrence of such events of default may result in the acceleration of all amounts due under 2030 Notes. The 2030 Notes were not eligible for conversion as of March 31, 2026. No sinking fund is provided for the 2030 Notes.

The 2030 Notes are general unsecured obligations of the Company and rank senior in right of payment to all of Company's existing and future indebtedness that is expressly subordinated in the right of payment to the 2030 Notes; equal in right of payment with all of the Company's existing and future senior, unsecured indebtedness; effectively subordinated to any of the Company's existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness; and structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity if any, of the Company's current or future subsidiaries. As of March 31, 2026, none of the conditions permitting the holders of the 2030 Notes to convert their notes early had been met. Therefore, the 2030 Notes are classified as long-term debt.

The Company accounted for the issuance of the 2030 Notes as a single liability measured at its amortized cost, as no embedded features require bifurcation and recognition as derivatives.

The carrying value of the 2030 Notes, net of unamortized debt issuance costs of $5.8 million, was $219.2 million as of March 31, 2026. Interest expense related to the amortization of debt issuance costs was $1.9 million and $0.3 million for the three months ended March 31, 2026 and 2025, respectively. The effective interest rate on the 2030 Notes is 3.43%.

Shares may be repurchased in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Securities and Exchange Act of 1934 (the "Exchange Act").

**10. 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 awards (RSUs and PSUs), employee stock purchase rights and the 2030 Notes, 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):

**11. Income Taxes**

We recorded a provision for income taxes of $2.2 million and $0.9 million for the three months ended March 31, 2026 and 2025, respectively. The Company's income tax provision for the three months ended March 31, 2026 and 2025 primarily consisted of U.S. federal and state taxes.

We had $8.3 million of unrecognized tax benefits as of March 31, 2026.

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.

***Statement of Cash Flows Income Taxes Paid Disclosure***

Cash payments of U.S. federal, state and foreign income taxes, net of refunds, during the three months ended March 31, 2026 were as follows (in thousands):

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted in the U.S. The OBBBA introduces significant provisions, including the permanent extension of certain expiring provisions under the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation contains multiple effective dates, with some provisions effective in 2025 and others implemented through 2027. The Company has considered the impact of OBBBA on the Company's annual effective tax rate, mainly the reduction in the R&D credit from the Section 280(c) election. The tax effects of the enacted legislation are reflected in the three months ended March 31, 2026 and there was no material impact on our effective tax rate as of March 31, 2026. The Company will continue to monitor and assess the impact of OBBBA on our consolidated financial statements.

**12. Segment and Geographic Information**

ASC 280 *Segment Reporting*, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker ("CODM") to assess performance and to decide how to allocate resources. The Company manages its business on the basis of one reportable segment and one operating segment and derives revenues from two sources: products revenue and services revenue.

The Company's CODM is our Chief Executive Officer, Dhrupad Trivedi. Our CODM assesses the performance of the Company and decides how to allocate resources based upon consolidated net income, which is also reported within the condensed consolidated statements of operations. The CODM uses consolidated net income to monitor period-over-period results, to assess financial performance and decide where to allocate additional resources within the business. The CODM does not regularly review significant classifications of expenses outside those shown on the condensed consolidated statements of operations.

We report customer revenues in three broad geographic regions: the Americas, APJ and EMEA regions. The Americas region comprises the United States and 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 geographic view aligns with how we manage the business and maps our product portfolio to customer verticals.

The following table depicts the disaggregation of revenue by geographic region based on the ship to location of our customers (in thousands):

| Deferred revenue, current | 84298 | 80824 |
| Deferred revenue, non-current | 62864 | 61982 |

---

We receive payments from customers based upon billing cycles. Invoice payment terms usually range from 30 to 90 days.

Accounts receivable are recorded when the right to consideration becomes unconditional.

Contract assets include amounts related to our contractual right to consideration for performance obligations not yet billed and are included in prepaid and other current assets in the condensed consolidated balance sheets. The amounts were immaterial as of March 31, 2026 and December 31, 2025.

------

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 $29.6 million and $26.1 million during the three months ended March 31, 2026 and 2025, 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, 2026, the current and non-current portions of deferred contract acquisition costs were $8.4 million and $5.5 million, respectively. As of December 31, 2025, the current and non-current portions of deferred contract acquisition costs were $8.3 million and $5.7 million, respectively. Related amortization expense was $1.9 million and $1.7 million for the three months ended March 31, 2026 and 2025, respectively.

We had no impairment loss in relation to the costs capitalized and no asset impairment charges related to contract assets during the three months ended March 31, 2026 and 2025.

***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):

**14. Subsequent Event**

On April 28, 2026, the Company announced that the Board of Directors approved a quarterly cash dividend. The dividend, in the amount of $0.06 per share outstanding, will be paid on June 1, 2026 to stockholders of record on May 15, 2026. Future dividends will be subject to further review and approval by the Board of Directors in accordance with applicable law. The Board of Directors reserves the right to adjust or withdraw the quarterly dividend in future periods as it reviews the Company's capital allocation of Directors strategy from time-to-time.

**ITEM 2. &nbsp;&nbsp;&nbsp;&nbsp;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 the 2025 Annual Report.*

**Overview**

We are a global provider of secure application and network solutions that protect, optimize, and scale business-critical systems across on-premises, hybrid cloud, and edge environments. Our network infrastructure and security products are designed to enable large enterprises, service providers, and cloud platforms worldwide to deliver performance, reliability, and protection against cyber threats, while preparing their networks for the demands of AI and next-generation applications.

We sell our solutions globally to service providers and enterprises who are looking to modernize and secure their digital infrastructure. Our service provider customers rely on scalable, efficient, and secure networks to deliver connectivity, cloud and other services that may generate revenue to their customers. Our enterprise customers require secure application delivery, AI-ready infrastructure, and are increasingly concerned about the landscape of cybersecurity threats across their complex networks. 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 significantly.

In February 2025, we acquired the assets and key personnel of ThreatX Protect, which expanded our cybersecurity portfolio with WAAP protection (web application and application programming interfaces). We offer protection under A10 Defend ThreatX Protect. In March 2025, the Company issued the 2030 Notes and received net proceeds from the offering of approximately $217.7 million.

A10's portfolio brings together secure application delivery, DDoS and API protection, and unified management into a cohesive platform that integrates with existing network architectures and leading public cloud environments. We deliver these capabilities through flexible deployment models, including software, cloud-native, and hardware form factors that are tailored to the scale and requirements of our customers. We generate revenue primarily from the sale of our secure networking and cybersecurity solutions and related support services. These offerings are delivered through a combination of direct and channel-based sales, with most customers purchasing maintenance and support alongside their initial deployment and renewing that support as contracts expire.

We derive revenue from two sources: (i) products revenue, which includes hardware, perpetual software licenses and subscription offerings, which include term-based license agreements; and (ii) services revenue, which includes PCS, professional services, training and SaaS offerings. Revenue for term-based license agreements is recognized at a point in time when the Company delivers the software license to the customer and over time once the subscription term has commenced. For our SaaS 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 over time as the services are provided. A substantial portion of our revenue is from sales of our products and services through distribution channels, such as resellers and distributors. Our customers predominantly purchase PCS services in conjunction with purchases of our products.

We operate worldwide across the Americas, EMEA, and Asia Pacific, supported by a hybrid go-to-market model that combines a direct, high-touch sales organization with a broad ecosystem of distributors, resellers, and system integrators. 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, 2026, (i) 67% of our total revenue was generated from the Americas region, of which 62% was generated from the United States and 5% was generated from the Americas-other, (ii) 19% of our total revenue was generated from the APJ region and (iii) 14% of our total revenue was generated from the EMEA region. During the three months ended March 31, 2025, (i) 51% of our total revenue was generated from the Americas region, of which 46% was generated from the United States and 5% was generated from the Americas-other, (ii) 28% of our total revenue was generated from the APJ region and (iii) 21% of our total revenue was generated from the EMEA region. One of our priorities is to strengthen our sales efforts in North America. During the three months ended March 31, 2026 and 2025, our enterprise customers accounted for 56% and 41% of our total revenue, respectively, and our service provider customers accounted for 44% and 59% of our total revenue, 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 55% and 44% of our total revenue for the three months ended March 31, 2026 and 2025, 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, 2026, we had $57.9 million of cash and cash equivalents and $311.9 million of marketable securities. Cash provided by operating activities was $2.2 million during the three months ended March 31, 2026, compared to $17.2 million in the same period of 2025.

We continue to invest in innovation that strengthens our leadership in secure infrastructure, expands our cybersecurity capabilities, and positions A10 at the intersection of network performance, protection, and AI-driven workloads. Our strategy is grounded in disciplined capital allocation and a commitment to deliver durable revenue growth, expanding recurring revenue, and strong cash flow generation.

Enhanced U.S. tariffs, import/export restrictions and countermeasures taken by affected countries are contributing to macroeconomic volatility which in turn is impacting demand and our cost inputs. Spending patterns remain uneven due to the unpredictable impact of trade policies, and we may need to implement tariff-related input cost increases.

***Net 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 (ii) services revenue, which includes PCS, professional services, training and SaaS offerings.

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, a small 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 SaaS 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, 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 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 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):

***Three Months Ended March 31, 2026 and 2025***

Total net revenue increased $8.9 million, or 13%, during the three months ended March 31, 2026, compared to the same period of 2025. Changes in revenue were due primarily to (i) an increase of $17.0 million in the Americas region, comprised of increases of $16.7 million in the United States and $0.3 million in Americas-other, (ii) a decrease of $4.4 million in the APJ region, and (iii) a decrease of $3.7 million in the EMEA region. The overall increase in revenue was attributable to a $15.1 million increase in revenue from enterprise customers, partially offset by a $6.2 million decrease in revenue from service provider customers during the three months ended March 31, 2026 compared to the same period of 2025. Products revenue increased $8.0 million, of which the Americas region increased $15.4 million, partially offset by decreases of $3.7 million in the APJ region and $3.7 million in the EMEA region for the three months ended March 31, 2026, compared to the same period of 2025. Services revenue increased $0.9 million, of which the Americas region increased $1.6 million, partially offset by a decrease of $0.7 million in the APJ region for the three months ended March 31, 2026, compared to the same period of 2025. Services revenue in the EMEA region was flat for the three months ended March 31, 2026, compared to the same period of 2025.

Products revenue increased $8.0 million, or 22%, during the three months ended March 31, 2026 compared to the same period of 2025, as a result of an increase in demand from our enterprise customers in the Americas and EMEA regions.

Services revenue increased $0.9 million, or 3%, during the three months ended March 31, 2026, compared to the same period of 2025, as a result of an increase in demand from our service provider and enterprise customers in the Americas region.

During the three months ended March 31, 2026, $50.5 million, or 67% of total revenue, was generated from the Americas region, which represents a 51% increase in revenue compared to the same period of 2025. The increase was primarily due to higher products revenue due to an increase in demand from our service provider and enterprise customers in the Americas region.

------

During the three months ended March 31, 2026, $14.2 million, or 19% of total revenue, was generated from the APJ region, which represents a 24% decrease compared to the same period of 2025. The decrease was primarily due to lower products and services revenue due to a decrease in demand from our service provider customers in the APJ region.

During the three months ended March 31, 2026, $10.3 million, or 14% of total revenue, was generated from the EMEA region, which represents an 27% decrease compared to the same period of 2025. The decrease was primarily due to lower products revenue due to a decrease in demand from our service provider customers in the EMEA region.

***Cost of Net Revenue, Gross Margin and Gross Profit***

***Cost of Net Revenue***

Cost of products revenue is primarily comprised of cost of third-party manufacturing services and cost of inventory for the hardware component of our products. Our component suppliers change their selling prices frequently in response to market trends, including industry-wide increases in demand. Cost of products revenue also includes warehouse personnel costs, shipping costs, inventory write-downs, certain allocated facilities and information technology infrastructure costs, and expenses associated with logistics and quality control.

Cost of services revenue is primarily comprised of personnel costs for our technical support, training and professional service teams. Cost of services revenue also includes the costs of inventory used to provide hardware replacements to end- customers under PCS contracts and certain allocated facilities and information technology infrastructure costs.

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

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** | **Increase (Decrease)** | **Increase (Decrease)** |
| | **2026** | **2025** | **Amount** | **Percent** |
| Cost of net revenue: |  |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Products | $8930 | $7263 | $1667 | 23.0% |
| &nbsp;&nbsp;&nbsp;&nbsp;Services | 6346 | 6179 | 167 | 2.7 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total cost of net revenue | $15276 | $13442 | $1834 | 13.6% |

---

Products cost of revenue increased 23.0% during the three months ended March 31, 2026, compared to the same period of 2025, primarily due product and regional mix.

Services cost of revenue increased 2.7% during the three months ended March 31, 2026, compared to the same period of 2025, primarily driven by an increase in personnel-related support costs and the mix of services delivered, which include technical support, training and service costs.

***Gross Margin***

Gross margin may vary and be unpredictable from period to period due to a variety of factors. These may include the mix of revenue from each of our regions, the mix of our products sold within a period, discounts provided to customers, cost of inventory for the hardware component of our products, inventory write-downs and foreign currency exchange rates.

Our sales are generally denominated in U.S. Dollars; however, in Japan, our sales are denominated in Japanese Yen.

Any of the factors noted above can generate either a favorable or unfavorable impact on gross margin.

A summary of our gross profit and gross margin is as follows (dollars in thousands):

---

Products gross margin decreased 0.1% to 79.7% during the three months ended March 31, 2026, compared to the same periods of 2025, primarily due to product and regional mix.

Services gross margin remained consistent at 79.5% for both the three months ended March 31, 2026 and 2025. Service gross margin is impacted by the mix of services delivered, which include technical support, training and service costs.

***Operating Expenses***

Our operating expenses consist of sales and marketing, research and development, general and administrative and restructuring expenses. The largest component of our operating expenses is personnel costs which consist of wages, benefits, bonuses, and, with respect to sales and marketing expenses, sales commissions. Personnel costs also include stock-based compensation.

A summary of our operating expenses is as follows (dollars in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** | **Increase (Decrease)** | **Increase (Decrease)** |
| | **2026** | **2025** | **Amount** | **Percent** |
| Operating expenses: |  |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Sales and marketing | $20014 | $19545 | $469 | 2.4% |
| &nbsp;&nbsp;&nbsp;&nbsp;Research and development | 19018 | 15900 | 3118 | 19.6 |
| &nbsp;&nbsp;&nbsp;&nbsp;General and administrative | 7693 | 8472 | (779) | (9.2) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total operating expenses | $46725 | $43917 | $2808 | 6.4% |

---

***Sales and Marketing***

Sales and marketing expenses are our largest functional category of operating expenses and primarily consist of personnel costs. Sales and marketing expenses also include the cost of marketing programs, trade shows, consulting services, promotional materials, demonstration equipment, depreciation and certain allocated facilities and information technology infrastructure costs.

Sales and marketing operating expenses increased $0.5 million, or 2.4%, in the three months ended March 31, 2026, compared to the same period in 2025, primarily due to an increase in personnel costs.&nbsp;&nbsp;&nbsp;&nbsp;

For the full year 2026, we expect sales and marketing expenses to increase modestly from 2025 levels as we continue to apply a disciplined approach to focus our investments in areas that offer the greatest opportunities.

***Research and Development***

Research and development efforts are focused on new product development and on developing additional functionality for our existing products. These expenses primarily consist of personnel costs, and, to a lesser extent, prototype materials,

------

depreciation and certain allocated facilities and information technology infrastructure costs. We expense research and development costs as incurred.

Research and development operating expenses increased $3.1 million, or 19.6%, in the three months ended March 31, 2026, compared to the same period in 2025, primarily due to an increase in personnel costs.

For the full year 2026, we expect research and development expenses to increase from 2025 levels reflecting strategic investments in our growth priorities, including cybersecurity technology and AI technologies.

***General and Administrative***

General and administrative expenses primarily consist of personnel costs, professional services and office expenses. General and administrative personnel costs include executive, finance, human resources, information technology, facility and legal related expenses. Professional services primarily consist of fees for outside accounting, tax, legal, recruiting and other administrative services.

General and administrative operating expenses decreased $0.8 million, or 9.2%, in the three months ended March 31, 2026, compared to the same period in 2025, primarily due to a decrease in personnel costs.

For the full year 2026, we expect general and administrative expenses to increase modestly from 2025 levels as we continue to apply a disciplined approach to focus our investments in areas that offer the greatest opportunities.

***Non-Operating Income (Expense)***

Non-Operating income, net, consists primarily of interest income earned on our cash and cash equivalents and marketable securities, interest expense on the 2030 Notes, foreign currency exchange gains and losses and fair value adjustments on investments in publicly held equity securities. Foreign currency exchange gains and losses are primarily a result of fluctuations in the Japanese Yen versus the U.S. Dollar.

*Interest Income*

Interest income was $3.4 million and $1.8 million in the three months ended March 31, 2026 and 2025, respectively.

*Interest Expense*

Interest expense was $1.9 million and $0.3 million in the three months ended March 31, 2026, respectively, and was related to our outstanding 2030 Notes that were issued in March 2025.

*Other Income (Expense)*

The Company recorded $0.2 million of net losses and $0.2 million of net gains in other income (expense) in the three months ended March 31, 2026, and 2025 respectively, primarily from foreign currency exchange gains and losses from fluctuations in the Japanese Yen versus the U.S. Dollar.

***Provision for Income Taxes***

We recorded a provision for income taxes of $2.2 million and $0.9 million for the three months ended March 31, 2026 and 2025, respectively. The Company's income tax provisions for the three months ended March 31, 2026 and 2025 primarily consisted of U.S. federal and state taxes.

**Liquidity and Capital Resources**

As of March 31, 2026, we had cash and cash equivalents of $57.9 million, including $3.3 million held outside the United States in our foreign subsidiaries, and $311.9 million of marketable securities. We currently do not have any plans to repatriate our earnings from our foreign operations. As of March 31, 2026, we had working capital of $350.4 million, retained earnings of $13.8 million and total stockholders' equity of $220.8 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.

------

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. We may also elect to raise additional financing to help us pursue our business and strategic objectives. Any additional financing could be dilutive to our existing stockholders.

In March 2025, the Company issued the 2030 Notes and received net proceeds from the offering of approximately $217.7 million.

The Board of Directors has authorized various stock repurchase programs from time to time, including most recently, a twelve-month $50 million program approved November 7, 2023 (the "2023 Program"), a $50 million program approved November 7, 2024 (the "2024 Program") and a $75 million program approved May 1, 2025 (the "2025 Program"). 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. During the year ended December 31, 2025, the Company repurchased 3.7 million shares for a total cost of $68.9 million under the 2023 and 2024 Programs. During the three months ended March 31, 2026, the Company had repurchased 0.1 million shares for a total cost of $2.5 million under the 2025 Program.

In October 2021, the Board of Directors approved the initiation of a regular quarterly cash dividend on our common stock. The Company paid cash dividends of $0.06 per share outstanding, for a total of $4.3 million and $4.4 million in the three months ended March 31, 2026. The next dividend, in the amount of $0.06 per share, will be paid on June 1, 2026 to stockholders of record on May 15, 2026. 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 the Board of Directors 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.&nbsp;&nbsp;&nbsp;&nbsp;

***Statements of Cash Flows***

The following table summarizes our cash flow related activities (in thousands):

*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 three months ended March 31, 2026, cash provided by operating activities was $2.2 million, consisting of net income of $12.0 million, non-cash charges of $9.5 million and a decrease in cash resulting from the net change in operating assets and liabilities of $19.3 million. Our non-cash charges consisted primarily of depreciation and amortization expenses of $4.0 million and stock-based compensation expense of $4.8 million. The net change in our operating assets and liabilities

------

primarily reflects cash outflows from the changes in accrued liabilities of $11.8 million, accounts receivable of $7.0 million, prepaid expenses and other assets of $3.7 million and inventory of $2.1 million, partially offset by cash inflows from deferred revenue of $4.4 million and accounts payable of $0.9 million.

The unfavorable change in accrued liabilities was primarily due to payments for variable compensation. The unfavorable change in accounts receivable was attributable to timing of billing and cash collections. The unfavorable change in prepaid expenses and other assets was attributable to an increase in prepaid accounting and marketing expenses. The unfavorable change in inventory was attributable to the timing of product shipments. The favorable change in deferred revenue was attributable to the timing of service contract bookings. The favorable change in accounts payable was attributable to the timing of payments to vendors.

During the three months ended March 31, 2025, cash provided by operating activities was $17.2 million, consisting of net income of $9.5 million, non-cash charges of $10.7 million and a decrease in cash resulting from the net change in operating assets and liabilities of $3.0 million. Our non-cash charges consisted primarily of depreciation and amortization expenses of $3.4 million and stock-based compensation expense of $6.0 million. The net change in our operating assets and liabilities primarily reflects cash outflows from the changes in accrued liabilities of $8.2 million, accounts payable of $5.6 million and prepaid expenses and other assets of $2.9 million, partially offset by cash inflows from accounts receivable of $10.5 million deferred revenue of $2.0 million and inventory of $1.2 million.

The unfavorable change in accrued liabilities was primarily due to a decrease in accrued variable compensation. The unfavorable change in accounts payable was attributable to the timing of payments to vendors. The unfavorable change in prepaid expenses and other assets was attributable to an increase in prepaid accounting and marketing expenses. The favorable change in accounts receivable was attributable to timing of billing and cash collections. The favorable change in deferred revenue was attributable to the timing of service contract bookings and the acquisition of ThreatX Protect deferred revenue. The favorable change in inventory was attributable to the timing of product shipments.

*Cash Flows from Investing Activities*

During the three months ended March 31, 2026, cash used in investing activities was $8.7 million, consisting of purchases of marketable securities of $64.3 million and capital expenditures of $2.9 million, partially offset by maturities of marketable securities of $58.5 million.

During the three months ended March 31, 2025, cash used in investing activities was $34.7 million, consisting of purchases of marketable securities of $41.9 million, cash paid for the acquisition of ThreatX Protect of $19.1 million and capital expenditures of $4.5 million, partially offset by maturities of marketable securities of $30.7 million. See Note 5 - *Acquisition* for additional information.

*Cash Flows from Financing Activities*

During the three months ended March 31, 2026, cash used in financing activities was $6.8 million, consisting of cash dividend payments of $4.3 million and repurchases of common stock of $2.5 million.

During the three months ended March 31, 2025, cash provided by financing activities was $166.3 million and primarily consisting of $217.7 million in net proceeds from the issuance of the 2030 Notes, $47.0 million used for repurchases of common stock and $4.4 million used for cash dividend payments.

***Contractual Obligations***

Our contractual obligations consist of non-cancellable operating lease arrangements and totaled $7.6 million as of March 31, 2026. Our operating lease arrangements expire on various dates through April 2028. These arrangements require us to pay certain operating expenses, such as taxes, repairs and insurance, and contain renewal and escalation clauses.

------

**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 critical accounting policies and estimates are disclosed in Part II – Item 7, "Critical Accounting Estimates" of the 2025 Annual Report. There have been no material changes to the Company's critical accounting policies and estimates during the three months ended March 31, 2026.

**ITEM 3. &nbsp;&nbsp;&nbsp;&nbsp;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 $0.2 million of net foreign exchange losses and $0.2 million of net foreign exchange gains during the three months ended March 31, 2026 and 2025, 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 typically comprised of corporate securities, U.S. Treasury and agency securities, commercial paper, asset-backed securities and equity securities of publicly traded companies. We do not enter into investments for trading or speculative purposes. As of March 31, 2026, our investment portfolio included marketable securities with an aggregate amortized cost basis of $312.0 million and a fair value of $311.9 million. The effect of a hypothetical 10% change in interest rates would not have 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, 2026 (in thousands):

---

| | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|
| |<br>**(150 BPS)** |<br>**(100 BPS)** |<br>**(50 BPS)** | **Fair Value as of**<br>**3/31/2026** |<br>**50 BPS** |<br>**100 BPS** |<br>**150 BPS** |
| Marketable securities | $314921 | $313963 | $312946 | $311867 | $310729 | $309530 | $308270 |

---

**ITEM 4. CONTROLS AND PROCEDURES**

***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, 2026, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (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.

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, 2026, 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, 2026, 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 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 the 2025 Annual Report. There have been no material changes to the risk factors disclosed in the 2025 Annual Report.*

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

On May 1, 2025, the Company announced that the Board of Directors authorized a new stock repurchase program of up to $75 million of its common stock (the "2025 Program"). The 2025 Program does not have a specified term or termination date. Under the 2025 Program, we can repurchase shares of our common stock in the open market, in privately negotiated transactions, in block trades or a combination of the foregoing. We are not obligated under the 2025 Program to repurchase any specific number or dollar amount of shares of common stock, and were able to modify, suspend or discontinue the 2025 Program at any time. Our management and the Board of Directors determined 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 funded repurchases from its existing cash balance and cash provided by operating activities.

Share repurchase activity during the three months ended March 31, 2026 was as follows (in thousands, except per share amounts):

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Periods** | **Total Number of Shares Purchased** | **Average Price Paid Per Share** | **Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs** | **Approximate Dollar Value of Shares That May Yet Be Purchased Under the Plans or Programs (1)** |
| January 1 - 31, 2026 | 25 | $17.52 | 439 | $55572 |
| February 1 - 28, 2026 | 113 | $18.27 | 2056 | $55133 |
| March 1 - 31, 2026 |  | $— |  | $53077 |
| Total | 138 |  |  | $53077 |

---

(1) The $53,077 thousand in the table above represents the amount available to repurchase shares under the 2025 Program as of March 31, 2026.

**ITEM 5. OTHER INFORMATION**

**Insider Adoption or Termination of Trading Arrangements**

During the fiscal quarter ended March 31, 2026, none of our directors or officers adopted or terminated a "Rule 10b5-1 trading arrangement" or a "non-Rule 10b5-1 trading arrangement" as those terms are defined in Regulation S-K, Item 408.
