On a trailing 12-month basis, enterprise revenue increased 8%, demonstrating a durable growth foundation. A10's focus on large enterprise customers in sectors like financials, gaming, and technology, which operate complex networks with high security and latency demands, is proving effective.

Profitability remains a core strength for A10. The gross margin in Q2 2025 was 80%, aligning with the company's stated goals of 80% to 82%. Product gross margin improved by 2.2% due to favorable product and regional mix, while services gross margin saw a 4.3% decrease, primarily due to increased personnel-related support costs and changes in the mix of services delivered. Adjusted EBITDA for Q2 2025 was $19.7 million, representing 28.3% of revenue, well within the long-term target range of 26% to 28%. Non-GAAP net income for the quarter was $15.5 million, or $0.21 per diluted share.

A10's balance sheet reflects robust liquidity and disciplined capital management. As of June 30, 2025, the company held $252.9 million in cash and cash equivalents and $114.5 million in marketable securities, totaling $367.4 million. Working capital stood at $348.9 million. In March 2025, A10 strategically issued $225 million in 2.75% Convertible Senior Notes due 2030, generating net proceeds of approximately $217.7 million, which bolstered its cash position and provided flexibility for future investments. The company consistently returns capital to shareholders, having authorized a new $75 million share repurchase program in May 2025, with $71.1 million remaining as of June 30, 2025. A quarterly cash dividend of $0.06 per share was approved, underscoring management's commitment to shareholder value.
