The words “believe,” “may,” “will,” “potentially,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “project,” “plan,” “expect,” and similar expressions that convey uncertainty of future events or outcomes are intended to identify forward-looking statements.

    These forward-looking statements include, but are not limited to, statements concerning the following:
    • our strategy, business plan and our ability to effectively manage our growth and business operations;
    • our expectations with respect to recognizing revenue related to remaining performance obligations;
    • our expectations with respect to demand for our products and services;
    • our plans to introduce new products;
    • our investment plans, including with respect to our sales and marketing organizations, distribution channel programs and increasing awareness of our solutions on a global basis;
    • loss or delay of expected purchases by our largest end-customers;
    • our expectations concerning relationships with third parties;
    • our expectations with respect to the realization of our tax assets and our unrecognized tax benefits;
    • our plans with respect to the repatriation of our earnings from our foreign operations;
    • our ability to maintain profitability while continuing to invest in our sales, marketing, product development, distribution channel partner programs and research and development teams;
    • our expectations regarding our future costs and expenses;
    • variability of our gross margin and the factors affecting it;
    • our expectations with respect to liquidity position and future capital requirements;
    • our stock repurchase program and our quarterly cash dividends;
    • our accounting policies and estimates;
    • fluctuations in currency exchange rates;
    • the cost and potential outcomes of litigation;
    • future acquisitions of or investments in complementary companies, products, services or technologies; and
    • our evaluations and expectations with respect to the potential impacts of OBBBA (as defined below).

    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, 2025. 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; our ability to maintain or improve our competitive position; competitive and execution risks related to cloud-based computing trends; 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; 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; 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, 2024.

    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.

    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”) 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 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.

    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 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 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, 2024 has been derived from our audited financial statements, which are included in our 2024 Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 25, 2025 (the “2024 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. 

    10


    These financial statements and accompanying notes should be read in conjunction with the financial statements and accompanying notes thereto in the 2024 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

    Business Combinations

    We use our best estimates and assumptions to allocate the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. We apply significant judgment in determining the fair value of the intangible assets acquired, which involves the use of significant estimates and assumptions with respect to revenue growth rates, royalty rate and technology migration curve. While we use our best estimates and judgments, our estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially established in connection with a business combination as of the acquisition date. We continue to collect information and reevaluate these estimates and assumptions quarterly and record any adjustments to our preliminary estimates to goodwill provided that we are within the measurement period. Upon the conclusion of the final determination of the fair value of assets acquired or liabilities assumed during the measurement period, any subsequent adjustments are included in our condensed consolidated statements of operations.

    The results of operations for businesses acquired are included in the financial statements from the acquisition date. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.

    The Company’s other significant accounting policies are disclosed in Part II – Item 8, “Financial Statements and Supplementary Data” of the 2024 Annual Report. Aside from adding the Company’s significant accounting policy regarding business combinations, there have been no material changes to the Company’s significant accounting policies during the nine months ended September 30, 2025.

    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 September 30, 2025 and 2024, sales through a single distribution channel

    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.

    In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-09.

    There have been no other recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the three months ended September 30, 2025 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 September 30, 2025 and December 31, 2024, foreign exchange forward currency contracts not designated as hedging instruments had total notional amounts of $2.7 million and $7.6 million, respectively. These contracts have maturities of approximately 30 days. For the three months ended September 30, 2025 and 2024, the Company recorded an unrealized net losses of $14 thousand and $32 thousand, respectively, in its condensed consolidated statements of operations related to these contracts. For the nine months ended September 30, 2025 and 2024, the Company recorded unrealized net losses of $36 thousand and $0.3 million, respectively, in its condensed consolidated statements of operations related to these contracts. For the three months ended September 30, 2025 and 2024, the Company recorded a realized net gain of $71 thousand and a realized net loss of $1.1 million, respectively, and for the nine months ended September 30, 2025 and 2024, the Company recorded a realized net loss of $0.4 million and a realized net gain of $3.9 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 September 30, 2025, foreign exchange forward currency contracts designated as hedging instruments had notional amounts of $9.4 million. As of December 31, 2024, there were no outstanding foreign exchange forward contracts designated as hedging instruments.

    5. Acquisition

    ThreatX Protect Business
    15



    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.

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.

    19


    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 September 30, 2025. 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 September 30, 2025, 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 $6.5 million, was $218.5 million as of September 30, 2025. Interest expense related to the amortization of debt issuance costs was $1.9 million and $4.1 million for the three and nine months ended September 30, 2025. The effective interest rate on the 2030 Notes is 3.43%.

    8. 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 April 2028. 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 September 30, 2025.

    Rent expense was $1.2 million and $1.2 million for the three months ended September 30, 2025 and 2024, respectively, and was $3.7 million and $3.6 million for the nine months ended September 30, 2025 and 2024, respectively.

    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 $11.2 million as of September 30, 2025.

    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.

    Stock Repurchase Programs

    On November 1, 2022, the Company announced that the Board authorized a stock repurchase program of up to $50 million of its common stock over a period of twelve months. On November 7, 2023, the Company announced that the Board authorized a stock repurchase program of up to $50 million of its common stock over a period of twelve months. These repurchase programs were active for twelve months and are expired.

    On November 7, 2024, the Company announced that the Board authorized a stock repurchase program of up to $50 million of its common stock (the “2024 Program”). The 2024 Program did not have a specified term or termination date. The Board terminated the 2024 Program on May 1, 2025.

    On May 1, 2025, the Company announced that the Board 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. During the three months ended September 30, 2025, we repurchased 633,985 shares for a total of $11.0 million or $17.41 per share under the 2025 Program. As of September 30, 2025, the Company had $60.1 million available to repurchase shares under the 2025 Program.

    Under the Company’s stock repurchase programs, repurchased shares are held in treasury at cost. The Company’s stock repurchase programs do not obligate it 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 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 options, RSUs, 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 $1.8 million and $1.8 million for the three months ended September 30, 2025 and 2024, respectively, and $4.1 million and $4.8 million for the nine months ended September 30, 2025 and 2024, respectively The Company’s income tax provision for the three and nine months ended September 30, 2025 and 2024 primarily consisted of U.S. federal and state taxes.

    We had $8.5 million of unrecognized tax benefits as of September 30, 2025. 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 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 period of enactment ended September 30, 2025 and there was no material impact on our effective tax rate as of August 30, 2025. 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):

    Contract Balances
    The following table reflects contract balances with customers (in thousands):
     As of September 30, 2025As of December 31, 2024
    Accounts receivable, net$61,578 $76,687 
    Deferred revenue, current82,017 78,335 
    Deferred revenue, non-current61,470 69,924 

    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 September 30, 2025 and December 31, 2024.

    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 $26.3 million and $28.2 million during the three months ended September 30, 2025 and 2024, respectively, and we recognized revenue of $63.6 million and $67.2 million during the nine months ended September 30, 2025 and 2024, 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 September 30, 2025, the current and non-current portions of deferred contract acquisition costs were $6.9 million and $4.6 million, respectively. As of December 31, 2024, the current and non-current portions of deferred contract acquisition costs were $6.2 million and $4.4 million, respectively. Related amortization expense was $1.7 million and $2.0 million for the three months ended September 30, 2025 and 2024, respectively, and was $4.3 million and $4.9 million for the nine months ended September 30, 2025 and 2024, 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 nine months ended September 30, 2025 and 2024.

    25


    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):
    As of September 30, 2025
    Within 1 year$82,017 
    Next 2 to 3 years48,826

    14. Subsequent Event

    On November 4, 2025, the Company announced that the Board approved a quarterly cash dividend. The dividend, in the amount of $0.06 per share outstanding, will be paid on December 1, 2025 to stockholders of record on November 17, 2025. Future dividends will be subject to further review and approval by the Board in accordance with applicable law. The Board reserves the right to adjust or withdraw the quarterly dividend in future periods as it reviews the Company’s capital allocation strategy from time-to-time.

    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 the 2024 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 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 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 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.

    27


    During the three months ended September 30, 2025, (i) 65% of our total revenue was generated from the Americas region, of which 61% was generated from the United States and 4% was generated from the Americas-other, (ii) 22% of our total revenue was generated from the APJ region and (iii) 12% of our total revenue was generated from the EMEA region. During the three months ended September 30, 2024, (i) 51% of our total revenue was generated from the Americas region, of which 45% was generated from the United States and 6% was generated from the Americas-other, (ii) 34% 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 nine months ended September 30, 2025, (i) 59% of our total revenue was generated from the Americas region, of which 54% was generated from the United States and 5% was generated from the Americas-other, (ii) 25% of our total revenue was generated from the APJ region and (iii) 16% of our total revenue was generated from the EMEA region. During the nine months ended September 30, 2024, (i) 49% of our total revenue was generated from the Americas region, of which 43% was generated from the United States and 7% was generated from the Americas-other, (ii) 36% of our total revenue was generated from the APJ region and (iii) 15% 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 September 30, 2025 and 2024, our enterprise customers accounted for 36% and 45% of our total revenue, respectively, and our service provider customers accounted for 64% and 55% of our total revenue, respectively. During the nine months ended September 30, 2025 and 2024, our enterprise customers accounted for 39% and 43% of our total revenue, respectively, and our service provider customers accounted for 61% and 57% 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 51% and 44% of our total revenue for the three months ended September 30, 2025 and 2024, respectively, and accounted for 45% and 37% of our total revenue for the nine months ended September 30, 2025 and 2024, 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 September 30, 2025, we had $86.6 million of cash and cash equivalents and $284.3 million of marketable securities. Cash provided by operating activities was $62.2 million during the nine months ended September 30, 2025, compared to $64.8 million in the same period of 2024.

    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 software license agreements; and (ii) services revenue, which includes post contract support (“PCS”), professional services, training and software-as-a-service 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 often includes a perpetual license to the included software. Additionally, a 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, 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 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.

    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):

    Products cost of revenue increased 7.6% and 11.4% during the three and nine months ended September 30, 2025, compared to the same periods of 2024, primarily due product and regional mix.

    Services cost of revenue increased 22.2% and 26.0% during the three and nine months ended September 30, 2025, compared to the same periods of 2024, 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.

    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,
    34


    bonuses, and, with respect to sales and marketing expenses, sales commissions. Personnel costs also include stock-based compensation.

    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 2.5%, in the three months ended September 30, 2025, compared to the same period in 2024, and increased $0.4 million, or 0.6%, in the nine months ended September 30, 2025, compared to the same period in 2024, primarily due to an increase in personnel costs.    

    For the full year 2025, we expect sales and marketing expenses to increase modestly from 2024 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 $2.6 million, or 16.8%, in the three months ended September 30, 2025, compared to the same period in 2024, and increased $6.0 million, or 13.5%, in the nine months ended September 30, 2025, compared to the same period in 2024, primarily due to an increase in personnel costs.

    For the full year 2025, we expect research and development expenses to increase from 2024 levels reflecting strategic investments in our growth priorities, including cybersecurity technology and artificial intelligence 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
    35


    legal related expenses. Professional services primarily consist of fees for outside accounting, tax, legal, recruiting and other administrative services.

    General and administrative operating expenses increased $0.5 million, or 7.0%, in the three months ended September 30, 2025, compared to the same period in 2024, and increased $3.4 million, or 17.8%, in the nine months ended September 30, 2025, compared to the same period in 2024, primarily due to an increase in professional services expense and personnel costs.

    For the full year 2025, we expect general and administrative expenses to increase modestly from 2024 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 $1.6 million in the three months ended September 30, 2025 and 2024, respectively, and was $8.2 million and $5.1 million in the nine months ended September 30, 2025 and 2024, respectively.

    Interest Expense

    Interest expense was $1.9 million and $4.1 million in the three and nine months ended September 30, 2025, respectively, and was related to our outstanding 2030 Notes that were issued in March 2025. The Company recorded no interest expense in the three and nine months ended September 30, 2024.

    Other Income (Expense)

    The Company recorded $0.5 million of net losses and $0.3 million of net gains in other income (expense) in the three and nine months ended September 30, 2025, respectively, primarily from foreign currency exchange gains from fluctuations in the Japanese Yen versus the U.S. Dollar. The Company recorded $2.3 million and $5.9 million of net gains in other income (expense) in the three and nine months ended September 30, 2024, respectively, primarily from foreign currency exchange gains from fluctuations in the Japanese Yen versus the U.S. Dollar and, to a lesser extent, net gains resulting from fair value adjustments on investments in publicly held equity securities. The Company had no investments in publicly held equity securities in the three and nine months ended September 30, 2025.

    Provision for Income Taxes

    We recorded a provision for income taxes of $1.8 million and $1.8 million for the three months ended September 30, 2025 and 2024, respectively, and $4.1 million and $4.8 million in the nine months ended September 30, 2025 and 2024, respectively. The Company’s income tax provisions for the three and nine months ended September 30, 2025 and 2024 primarily consisted of U.S. federal and state taxes.

    Liquidity and Capital Resources

    As of September 30, 2025, we had cash and cash equivalents of $86.6 million, including $4.2 million held outside the United States in our foreign subsidiaries, and $284.3 million of marketable securities. We currently do not have any plans to repatriate our earnings from our foreign operations. As of September 30, 2025, we had working capital of $340.0 million, accumulated deficit of $8.1 million and total stockholders’ equity of $206.2 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
    36


    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 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, 2024, the Company repurchased 2.1 million shares for a total cost of $28.9 million under the 2023 and 2024 Programs. During the nine months ended September 30, 2025, the Company had repurchased 3.3 million shares for a total cost of $62.0 million under the 2024 and 2025 Programs.

    In October 2021, the Board 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 $13.1 million in the three and nine months ended September 30, 2025. The next dividend, in the amount of $0.06 per share, will be paid on December 1, 2025 to stockholders of record on November 17, 2025. 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 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 nine months ended September 30, 2025, cash provided by operating activities was $62.2 million, consisting of net income of $32.3 million, non-cash charges of $28.3 million and an increase in cash resulting from the net change in operating assets and liabilities of $1.6 million. Our non-cash charges consisted primarily of depreciation and amortization expenses of $10.9 million and stock-based compensation expense of $15.2 million. The net change in our operating assets and liabilities primarily reflects cash inflows from the changes in accounts receivable of $14.8 million, inventory of $2.7 million and accrued liabilities of $0.4 million, partially offset by cash outflows from deferred revenue of $7.3 million, prepaid expenses and other assets of $6.9 million and accounts payable of $2.1 million.

    37


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

    During the nine months ended September 30, 2024, cash provided by operating activities was $64.8 million, consisting of net income of $31.8 million, non-cash charges of $19.5 million and an increase in cash resulting from the net change in operating assets and liabilities of $13.4 million. Our non-cash charges consisted primarily of depreciation and amortization expenses of $8.2 million and stock-based compensation expense of $12.3 million. The net change in our operating assets and liabilities primarily reflects cash inflows from the changes in accounts receivable of $8.4 million, accrued liabilities of $5.1 million, deferred revenue of $2.9 million and prepaid expenses and other assets of $0.8 million, partially offset by cash outflows from inventory of $1.9 million and accounts payable of $1.8 million.

    The favorable change in accounts receivable was attributed to timing of billing and cash collections. The favorable change in accrued expenses was primarily due to an increase in accrued variable compensation. The unfavorable change in inventory was attributable to the timing of product shipments. 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 state and federal taxes. The unfavorable change in deferred revenue was attributable to the timing of service contract bookings.

    Cash Flows from Investing Activities

    During the nine months ended September 30, 2025, cash used in investing activities was $215.1 million, consisting of purchases of marketable securities of $278.9 million, cash paid for the acquisition of ThreatX Protect of $19.1 million and capital expenditures of $13.5 million, partially offset by maturities of marketable securities of $96.4 million. See Note 5 - Acquisition for additional information on our acquisition of ThreatX Protect.

    During the nine months ended September 30, 2024, cash used in investing activities was $48.2 million, consisting of purchases of marketable securities of $127.3 million and capital expenditures of $9.9 million, partially offset by maturities and sales of marketable securities of $89.0 million.

    Cash Flows from Financing Activities

    During the nine months ended September 30, 2025, cash provided by financing activities was $144.3 million, consisting of proceeds from the sale on the Company’s 2030 Notes of $217.7 million, proceeds from common stock issued under the Company’s equity plans of $1.7 million, partially offset by repurchases of common stock of $62.0 million and cash dividend payments of $13.1 million.

    During the nine months ended September 30, 2024, cash used in financing activities was $35.8 million and primarily consisting of $24.3 million used for repurchases of common stock and $13.4 million used for cash dividend payments, partially offset by $1.9 million of proceeds from common stock issued under the Company’s equity plans.

    Contractual Obligations

    Our contractual obligations consist of non-cancellable operating lease arrangements and totaled $10.4 million as of September 30, 2025. 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.

    38


    The Company applied the fair value measurement requirements within ASC 820 Fair Value Measurements to evaluate the fair value of identifiable assets acquired and liabilities assumed in connection with its acquisition of ThreatX Protect in February 2025. The Company estimated fair value and remaining useful life of the intangible assets acquired based on the price that would be received if the Company were to sell the intangible assets in an orderly transaction between market participants. Intangible assets will be amortized on a straight-line basis over their remaining useful life. See Note 5 - Acquisition for additional information on our acquisition of ThreatX Protect.

    The Company’s other critical accounting policies and estimates are disclosed in Part II – Item 7, “Critical Accounting Estimates” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 25, 2025. There have been no material changes to the Company’s other critical accounting policies and estimates during the nine months ended September 30, 2025.

    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 $0.5 million of net foreign exchange losses and $0.3 million of net foreign exchange gains during the three and nine months ended September 30, 2025, respectively, and we recorded $1.3 million and $3.8 million of net foreign exchange gains during the three and nine months ended September 30, 2024, 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 September 30, 2025, our investment portfolio included marketable securities with an aggregate amortized cost basis of $283.7 million and a fair value of $284.3 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 September 30, 2025 (in thousands):

    Fair Value as of
     (150 BPS)(100 BPS)(50 BPS)9/30/202550 BPS100 BPS150 BPS
    Marketable securities$287,817 $286,668 $285,497 $284,304 $283,087 $281,848 $280,587 

    ITEM 4. CONTROLS AND PROCEDURES

    39


    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 September 30, 2025, 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 September 30, 2025, 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 September 30, 2025, 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.

    40


    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 2024 Annual Report. Except as disclosed below, there have been no material changes to the risk factors disclosed in the 2024 Annual Report.

    Risks Related to Intellectual Property, Litigation, Laws and Regulations

    Enhanced United States tariffs, import/export restrictions, Chinese regulations, countermeasures taken by affected countries or other trade barriers may have a negative effect on global economic conditions, financial markets and our business.

    There is currently significant uncertainty about the future relationship between the U.S. and various other countries, most significantly China, with respect to trade policies, treaties, tariffs and taxes. The current U.S. administration has imposed a range of tariff actions on U.S. trading partners. In April 2025, acting under the International Economic Emergency Powers Act (“IEEPA”), the Trump administration temporarily increased IEEPA tariffs on Chinese imports to 145% (reduced back to 30% in May 2025) and set a baseline 10% tariff applicable to almost every country, with exemptions for certain products. In August 2025, the United States increased reciprocal tariffs on many trading partners to individually-set levels, subject again to certain exemptions. Ongoing trade investigations, including investigations under Section 232 of the Trade Expansion Act and Section 301 of the Trade Adjustment Act, could also lead to greater restrictions on international trade and further increases in tariffs on goods imported into the U.S. These include investigations by the U.S. Trade Representative (“USTR”) into Chinese legacy semiconductors and the U.S. Department of Commerce (“Commerce”) into semiconductors and derivative articles, among other actions.

    On August 1, Commerce imposed 50% duties under Section 232 on certain articles of copper and copper derivative products, followed by Section 232 duties on imports of wood products in September. Commerce continues to investigate the national security impact of imports of myriad other products, including semiconductors, polysilicon, and pharmaceuticals, with decisions likely to be made later this year or early 2026. Further, the United States continues to negotiate and enter into trade agreement frameworks with various countries, which may result in lower tariffs on those trading partners. China has also imposed, or threaten to impose, various export restrictions on its products, including certain critical minerals, rare earth elements, and lithium-ion batteries. In response, President Trump has threatened to impose an additional 100% tariff on imports from China.

    Although A10's supply chain does not depend exclusively upon imports from China, an increase in tariffs generally will cause our costs to increase, which could narrow the profits we earn from sales of products requiring such materials and/or compel us to increase our prices to customers. Furthermore, while we are not presently aware of duties applicable to digital services, if trade restrictions or barriers are placed on our products by foreign governments, the prices for such products may increase, which may result in the loss of customers and harm to our business, financial condition and results of operations. There can be no assurance that we will not experience a disruption in business related to these or other changes in trade practices and the process of changing suppliers in order to mitigate any such tariff costs could be complicated, time consuming and costly.

    Furthermore, the U.S. tariffs may cause customers to delay orders as they evaluate where to take delivery of our products in connection with their efforts to mitigate their own tariff exposure. Such delays create forecasting difficulties for us
    41


    and increase the risk that orders might be canceled or never be placed. Current or future tariffs may also negatively impact our customers’ revenue, thereby causing an indirect negative impact on our sales. Any reduction in customers’ revenue, and/or any apprehension among distributors and customers of a possible reduction in such revenue, could cause an indirect negative impact on our own sales. As noted, the current U.S. administration has taken a variety of tariff actions against other countries, and other countries such as China have at times responded with retaliatory tariffs and non-tariff measures as trade negotiations continue. The duration and magnitude of these tariffs and other trade disruptions remains uncertain and could lead to economic decline in affected countries, which could negatively impact purchases of our products. Moreover, an increase in the cost of our products due to tariffs or other trade actions could cause us to be impacted to a greater degree than our competitors who are based in countries that are not subject to tariffs, placing us at a disadvantage. Simply put, future U.S. tariffs on imports and retaliatory tariffs could increase the cost of, and reduce demand for, our products, which may materially adversely affect our results of operations.

    Additionally, the current uncertainty about the future relationship between the U.S. and other countries with respect to the trade policies, treaties, taxes, sanctions, government regulations and tariffs makes it difficult to plan for the future. New developments in these areas, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between these nations and the U.S. Any of these factors could depress economic activity and restrict our access to suppliers or customers and have a material adverse effect on our business, financial condition and results of operations and affect our strategy. Given the uncertainty of further developments related to tariffs, international trade agreements and policies we can give no assurance that our business, financial condition and operating results would not be adversely affected.

    Risks Related to Our Convertible Indebtedness

    The issuance of shares of our common stock could depress the trading price of our common stock.

    We have the right to elect to settle conversion of the 2030 Notes either entirely in cash or in combination of cash and shares of common stock. Our election to convert the 2030 Notes into common stock may further dilute the economic and voting rights of our existing stockholders and/or reduce the market price of our common stock. In addition, the market’s expectation that conversions may occur could depress the trading price of our common stock even in the absence of actual conversions. Moreover, the expectation of conversions could encourage the short selling of our common stock, which could place further downward pressure on the trading price of our common stock. In addition, our issuance of additional shares of common stock will dilute the ownership interests of our existing common stockholders.

    We may be unable to raise the funds necessary to repurchase the 2030 Notes for cash following a fundamental change or to pay the cash amounts due upon maturity or conversion of the 2030 Notes, and our future indebtedness may limit our ability to repurchase the 2030 Notes or to pay any cash amounts due upon their maturity or conversion.

    Noteholders may, subject to a limited exception, require us to repurchase their 2030 Notes following a “fundamental change” (which is defined in the 2030 Notes Indenture to include certain change-of-control events and the delisting of our common stock) at a cash repurchase price generally equal to the principal amount of the 2030 Notes to be repurchased, plus accrued and unpaid interest, if any. Upon maturity of the 2030 Notes, we must pay their principal amount and accrued and unpaid interest in cash, unless they have been previously repurchased, redeemed or converted. In addition, all conversions of the 2030 Notes will be settled partially or entirely in cash. We may not have enough available cash or be able to obtain financing at the time we are required to repurchase the 2030 Notes or pay any cash amounts due upon their maturity or conversion. In addition, applicable law, regulatory authorities and the agreements governing our future indebtedness may restrict our ability to repurchase the 2030 Notes or to pay the cash amounts due upon their maturity or conversion. Our failure to repurchase 2030 Notes or to pay any cash amounts due upon their maturity or conversion when required will constitute a default under the indenture governing the 2030 Notes. A default under the 2030 Notes Indenture or the fundamental change itself could also lead to a default under agreements governing our other or future indebtedness, which may result in that other or future indebtedness becoming immediately payable in full. If repayment of the related indebtedness were to be accelerated after an applicable notice or grace periods, we may not have sufficient funds to satisfy all amounts due under the 2030 Notes, any other indebtedness, repurchase such notes or make cash payments upon conversion of such notes, if applicable.

    Provisions in the 2030 Notes Indenture could delay or prevent an otherwise beneficial takeover of us.

    Certain provisions in the 2030 Notes and the 2030 Notes Indenture could make a third-party attempt to acquire us more difficult or expensive. For example, if a takeover constitutes a fundamental change, then noteholders will have the right to require us to repurchase their 2030 Notes for cash. In addition, if a takeover constitutes a make-whole fundamental change, then we may be required to temporarily increase the conversion rate for the 2030 Notes. In either case, and in other cases, our obligations under the 2030 Notes and the 2030 Notes Indenture could increase the cost of acquiring us or otherwise discourage
    42


    a third party from acquiring us or removing incumbent management, including in a transaction that noteholders or holders of our common stock may view as favorable.

    The conversion of 2030 Notes could impair our financial position and liquidity.

    Because we must settle at least a portion of our conversion obligation for the 2030 Notes in cash, the conversion of 2030 Notes could materially and adversely affect our financial position and liquidity. Before December 1, 2029, noteholders will have the right to convert their 2030 Notes only upon the occurrence of certain events. From and after December 1, 2029, noteholders may convert their 2030 Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. However, many of the conditions that permit the conversion of 2030 Notes before December 1, 2029 are beyond our control. We could be required to expend a significant amount of cash to settle conversions, which could significantly harm our financial position and liquidity.

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

    On May 1, 2025, the Company announced that the Board 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 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 September 30, 2025 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)
    July 1 - 31, 20252 $20.14 2 $71,058 
    August 1 - 31, 2025599 $17.40 599 $60,637 
    September 1 - 30, 202533 $17.39 33 $60,060 
    Total634 $60,060 

    (1) The $60,060 thousand in the table above represents the amount available to repurchase shares under the 2025 Program as of September 30, 2025.

    ITEM 5. OTHER INFORMATION

    Insider Adoption or Termination of Trading Arrangements

    On September 12, 2025, Dhrupad Trivedi, President, Chief Executive Officer and Chairman of the Board of Directors, adopted a trading plan intended to satisfy Rule 10b5-1(c) under the Exchange Act with respect to the sale of up to 100,000 shares of our common stock between February 11, 2026 and August 28, 2026.
