"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.

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 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.

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.
