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

“A10 continued to solidify its strategic position as a leader in security-focused next-generation networking solutions supporting AI-related infrastructure, driving another quarter of double-digit revenue growth and sustained cash generation,” said Dhrupad Trivedi, President and Chief Executive Officer of A10 Networks. “The growing network traffic demands, increasing complexity, and A10’s competitive position at the intersection of traffic management and security continues to resonate in the marketplace. With an expanded portfolio, including our acquisition of TrojAI in June, we believe A10 has positioned itself as a vendor of choice for next-generation networking running critical applications.”
“We are deepening our engagement with leaders defining the AI infrastructure market. Our new agreement with Microsoft reflects a successful, long-standing relationship and stands as a powerful validation of the value we jointly deliver, The agreement is structured over a multi-year period, aligning both parties’ interests as deployment continues to scale,” continued Trivedi. “We believe it pairs our opportunity with Microsoft's scaled AI deployment, further solidifying our position as a partner of choice for the world's most demanding AI workloads, while establishing a durable, forward-looking foundation for a mutually beneficial relationship in the years ahead.”

“Our model has continued to convert growth into increased profitability, cash generation, and the return of capital to shareholders,” Trivedi added. “We have increased our full-year outlook based on the performance in the first half of 2026 and our visibility into the remainder of the year.”

Outlook

Management is updating their previous guidance to the following based on first-half performance and demand outlook:

•Full-year revenue growth of 12-14% over the prior year, an increase from previous guidance of 10-12% growth.

Forward-Looking Statements

This press release contains “forward-looking statements,” including statements regarding dividends and capital return, demand and market trends, strategy and competitive positioning, our commercial partnerships and agreements (including our agreement with Microsoft), financial performance and profitability, supply chain management, and 2026 financial guidance. 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 rates 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, 2026. 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 by excluding certain items that, while they may recur, can vary significantly in amount and timing or are not directly indicative of ongoing operational trends, and are used by the company’s management to evaluate operating performance, prepare budgets and forecasts, and assess performance relative to peer companies.

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) acquisition-related expense, (iii) amortization of acquired intangible assets, (iv) amortization of debt issuance costs, (v) certain legal expense, (vi) tax planning expense and (vii) income tax effect of non-GAAP items (i) to (vi) 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) amortization of acquired intangible assets. 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) acquisition-related expense, (iii) amortization of acquired intangible assets, (iv) certain legal expense and (v) tax planning expense. We define non-GAAP operating income as our GAAP income from operations excluding (i) stock-based compensation and related payroll tax, (ii) acquisition-related expense, (iii) amortization of acquired intangible assets, (iv) certain legal expense and (v) tax planning 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, net, (ii) depreciation and amortization expense, (iii) provision for income taxes, (iv) stock-based compensation and related payroll tax, (v) acquisition-related expense, (vi) certain legal expense and (vii) tax planning 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 and to facilitate comparison of operating results across reporting periods. 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.
