Forward Looking Statements

Item 8.01 contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act, including statements regarding the Company’s dividend program. These forward-looking statements involve risks and uncertainties. These forward-looking statements may be identified by terms such as “will,” “may,” “plans,” or the negative of these terms, and similar expressions intended to identify forward-looking statements.

These risks and uncertainties include, but are not limited to, any unforeseen need for capital which may require us to divert funds we may have otherwise used for the dividend and repurchase programs, which may in turn negatively impact our ability to administer the quarterly dividends or conduct repurchases. In addition, the timing and amount of future dividends, and amount and timing of future repurchases, if any, will be made as management deems appropriate and will depend on a variety of factors including stock price, market conditions, corporate and regulatory requirements (including applicable securities laws and regulations and the rules of The New York Stock Exchange), any additional constraints related to material inside information

A10 Networks Reports Financial Results for the First Quarter of 2025

Company Delivers Revenue Growth YoY and Expands Earnings Per Share

Board Authorizes New Buyback Program

SAN JOSE, Calif., May 1, 2025 -- A10 Networks, Inc. (NYSE: ATEN), a leading provider of secure application services and solutions, today announced financial results for its first quarter ended March 31, 2025.

First Quarter 2025 Financial Summary

•Revenue of $66.1 million, up 9% year-over-year compared to $60.7 million in the first quarter of 2024.

•GAAP gross margin of 79.7%; non-GAAP gross margin of 80.9% as a result of continued focus on operational execution of business model goals despite near-term volatility in the market.

•GAAP net income of $9.5 million (14.4% of revenue), or $0.13 per diluted share, compared to net income of $9.7 million (16.0% of revenue), or $0.13 per diluted share, in the first quarter of 2024.

•Non-GAAP net income of $15.0 million (22.7% of revenue), or $0.20 per diluted share, compared to non-GAAP net income of $12.7 million (21.0% of revenue), or $0.17 per diluted share in the first quarter of 2024.

•The Company returned $51.4 million to investors, having repurchased 2.4 million shares at an average price of $19.58 for a total of $47.0 million and having paid $4.4 million in cash dividends in the quarter.

•The Board of Directors approved a quarterly cash dividend of $0.06 per share, payable June 2, 2025 to stockholders of record at the close of business on May 15, 2025.

•The Board of Directors also authorized a new, $75 million share repurchase program.

A reconciliation between GAAP and non-GAAP information is contained in the financial statements below.

“A10 continued to deliver solid execution, benefiting from some stabilization in our service provider segment, particularly in North America, and steady progress in the enterprise segment,” said Dhrupad Trivedi, President and Chief Executive Officer of A10 Networks. “The recent acquisition of ThreatX Protect, which closed in February, bolsters our capabilities to protect against attacks on web applications and application programming interfaces (APIs), a key area of focus for enterprise customers. Overall, our increased focus on enterprise market continues to provide durable growth, and security-related revenue continues to grow faster than overall revenue. As a result of our continued focus on diversification, in terms of customer segments and geographies, we remain well-positioned to outperform the broader industry.”

“Simultaneously, we continue to navigate macroeconomic volatility from a position of strength with a robust balance sheet and an innovation engine aligned with secular growth trends,” continued Trivedi. “Service provider spending patterns could remain uneven due to unpredictable impact of trade policies causing customers to proceed cautiously. We are monitoring and jointly navigating tariff-related input cost increases with our customers, minimizing the impact on our profitability, though we are not completely immune to these challenges.”

“Overall, A10 is well-positioned strategically and the enhancements we have made in our enterprise-facing capabilities are paying off,” concluded Trivedi. “An expansion of adversarial global trade dynamics could temporarily depress overall demand, potentially impacting our near-term growth rate, but we continue to expect our growth to outpace the industry and continue to deliver our business model.”

Conference Call

Management will host a call at 1:30 p.m. Pacific time (4:30 p.m. Eastern time) today, May 1, 2025, to discuss these results. Interested parties may access the conference call by dialing (888) 506-0062 (toll-free) or (973) 528-0011 (international) and referencing access code: 977788.

Forward-Looking Statements

This press release contains “forward-looking statements,” including statements regarding our quarterly dividend payments and stock repurchase program, strategy, positioning, demand, U.S. trade policies and the impact thereof, growth rate, margin profile, profitability and return of capital. Forward-looking statements are subject to known and unknown risks and uncertainties and are based on assumptions that may prove to be incorrect, which could cause actual results to differ materially from those expected or implied by the forward-looking statements. Factors that may cause actual results to differ include 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, which may in turn negatively impact our ability to administer the quarterly dividends or the repurchase of our common stock; a significant decline in global macroeconomic or political conditions that have an adverse impact on our business and financial results; an expansion of adversarial global trade dynamics or other changes to international trade regulations; business interruptions related to our supply chain; our ability to manage our business and expenses if customers cancel or delay orders; 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 achieve or 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 network security; the success of any future acquisitions or investments in complementary companies, products, services or technologies; the ability of our sales team to execute well; our ability to shorten our close cycles; the ability of our channel partners to sell our products; variations in product mix or geographic locations of our sales; risks associated with our presence in international markets; weaknesses or deficiencies in our internal control over financial reporting; our ability to timely file periodic reports required to be filed under the Securities Exchange Act of 1934; and other risks that are described in “Risk Factors” in our periodic filings with the Securities and Exchange Commission, including our Form 10-K filed with the Securities and Exchange Commission on February 25, 2025. We do not intend to update or alter our forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law.

Non-GAAP Financial Measures

In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), we refer to certain non-GAAP financial measures, including non-GAAP net income, non-GAAP net income per basic and diluted share (or non-GAAP EPS), non-GAAP gross profit and gross margin, non-GAAP operating expenses, non-GAAP operating income and operating margin, Adjusted EBITDA and Adjusted EBITDA margin. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies.

A10 Networks considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the company, exclusive of unusual events or factors that do not directly affect what we consider to be our core operating performance and are used by the company's management for that purpose.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.

We define non-GAAP net income as our GAAP net income excluding: (i) stock-based compensation and related payroll tax, (ii) ThreatX Protect acquisition expense, (iii) ThreatX Protect intangible amortization, (iv) one-time legal expense and (v) income tax effect of non-GAAP items (i) to (iv) listed above. We define non-GAAP net income per basic and diluted share as our non-GAAP net income divided by our basic and diluted weighted-average shares outstanding. We define non-GAAP gross profit as our GAAP gross profit excluding (i) stock-based compensation and related payroll tax and (ii) ThreatX Protect intangible amortization. We define non-GAAP gross margin as our non-GAAP gross profit divided by our GAAP revenue. We define non-GAAP operating expenses as our GAAP operating expenses excluding (i) stock-based compensation and related payroll tax, (ii) ThreatX Protect acquisition expense, (iii) ThreatX Protect intangible amortization and (iv) one-time legal expense. We define non-GAAP operating income as our GAAP income from operations excluding (i) stock-based compensation and related payroll tax, (ii) ThreatX Protect acquisition expense, (iii) ThreatX Protect intangible amortization and (iv) one-time legal expense. We define non-GAAP operating margin as our non-GAAP operating income divided by our GAAP revenue. We define Adjusted EBITDA as our GAAP net income excluding (i) interest and other (income) expense, net, (ii) depreciation and amortization expense, (iii) provision for income taxes, (iv) stock-based compensation and related payroll tax, (v) ThreatX Protect acquisition expense, (iv) ThreatX Protect intangible amortization and (vi) one-time legal expense. We define Adjusted EBITDA margin as our Adjusted EBITDA divided by our GAAP revenue.

Non-GAAP financial measures are presented for supplemental informational purposes only for understanding the company's operating results.

Net income and earnings per share excluding adjustments are non-GAAP financial measures presented as supplemental financial measures to enable a user of the financial information to understand the impact of these adjustments on reported results. These financial measures should not be considered an alternative to net income, operating income, cash flows provided by operating activities, or any other measure of financial performance or liquidity presented in accordance with U.S. GAAP. Our adjusted net income and earnings per share may not be comparable to similarly titled measures of another company because companies may not all calculate adjusted net income and earnings per share in the same manner.

Forward-looking statements are subject to known and unknown risks and uncertainties and are based on assumptions that may prove to be incorrect, which could cause actual results to differ materially from those expected or implied by the forward-looking statements. Factors that may cause actual results to differ include 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, which may in turn negatively impact our ability to administer the quarterly dividends or the repurchase of our common stock; a significant decline in global macroeconomic or political conditions that have an adverse impact on our business and financial results; an expansion of adversarial global trade dynamics or other changes to international trade regulations; business interruptions related to our supply chain; our ability to manage our business and expenses if customers cancel or delay orders; 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 achieve or 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 network security; the success of any future acquisitions or investments in complementary companies, products, services or technologies; the ability of our sales team to execute well; our ability to shorten our close cycles; the ability of our channel partners to sell our products; variations in product mix or geographic locations of our sales; risks associated with our presence in international markets; weaknesses or deficiencies in our internal control over financial reporting; our ability to timely file periodic reports required to be filed under the Securities Exchange Act of 1934; and other risks that are described in “Risk Factors” in our periodic filings with the Securities and Exchange Commission, including our Form 10-K filed with the Securities and Exchange Commission on February 25, 2025. We do not intend to update or alter our forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law. This presentation and the accompanying oral presentation also include certain non-GAAP financial measures including non-GAAP net income, non-GAAP net income per basic and diluted share (or non-GAAP EPS), non- GAAP gross profit and gross margin, non-GAAP operating expenses, non-GAAP operating income and operating margin, Adjusted EBITDA and Adjusted EBITDA margin. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titles measures presented by other companies. A10 Networks considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the company, exclusive of unusual events or factors that do not directly affect what we consider to be our core operating performance and are used by the company’s management for that purpose. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. We define non-GAAP net income as our GAAP net income excluding: (i) stock-based compensation and related payroll tax, (ii) ThreatX Protect acquisition expense, (iii) ThreatX Protect intangible amortization, (iv) one-time legal expense and (v) income tax effect of non-GAAP items (i) to (iv) listed above. We define non-GAAP net income per basic and diluted share as our non-GAAP net income divided by our basic and diluted weighted-average shares outstanding. We define non-GAAP gross profit as our GAAP gross profit excluding (i) stock-based compensation and related payroll tax and (ii) ThreatX Protect intangible amortization. We define non-GAAP gross margin as our non-GAAP gross profit divided by our GAAP revenue. We define non-GAAP operating expenses as our GAAP operating expenses excluding (i) stock-based compensation and related payroll tax, (ii) ThreatX Protect acquisition expense, (iii) ThreatX Protect intangible amortization and (iv) one-time legal expense. We define non-GAAP operating income as our GAAP income from operations excluding (i) stock-based compensation and related payroll tax, (ii) ThreatX Protect acquisition expense, (iii) ThreatX Protect intangible amortization and (iv) one-time legal expense. We define non-GAAP operating margin as our non-GAAP operating income divided by our GAAP revenue. We define Adjusted EBITDA as our GAAP net income excluding (i) interest and other (income) expense, net, (ii) depreciation and amortization expense, (iii) provision for income taxes, (iv) stock- based compensation and related payroll tax, (v) ThreatX Protect acquisition expense, (iv) ThreatX Protect intangible amortization and (vi) one-time legal expense. We define Adjusted EBITDA margin as our Adjusted EBITDA divided by our GAAP revenue. Non-GAAP financial measures are presented for supplemental informational purposes only for understanding the company's operating results. A reconciliation between GAAP and non-GAAP financial measures can be found in the appendix to this document and in the accompanying financial results press release.
