* Outlook for High Single-Digit Growth: Management anticipates annual revenue growth in the high single-digit range, supported by normalizing service provider spending, expanding enterprise penetration, and continuous innovation in AI-enabled security, targeting gross margins of 80-82% and adjusted EBITDA margins of 26-28%. ## A Strategic Nexus: Cybersecurity, AI, and A10 Networks A10 Networks, Inc., established in 2004 and reincorporated in Delaware in 2014, has evolved into a leading provider of secure application solutions and services. The company's core mission is to empower intelligently connected organizations with enhanced cyber protection and digital responsiveness across dynamic IT and network infrastructures. A10's foundational strategy is deeply rooted in its alignment with two of the most powerful and non-discretionary catalysts influencing technology spending today: artificial intelligence (AI) and cybersecurity. The company's historical journey reflects a consistent adaptation to market demands. In early 2024, A10 faced headwinds from cautious spending by North American service providers, which temporarily impacted revenue. However, a strategic pivot to accelerate investments in the enterprise segment proved successful, driving enterprise revenue growth that outpaced consolidated figures. By the latter half of 2024 and into 2025, the service provider market began to normalize, validating A10's thesis that critical infrastructure and security investments are often delayed, not canceled. This intentional diversification across customer verticals and geographies, including the Americas, APJ, and EMEA, forms a core strength, enabling A10 to maintain momentum and resilience amidst ongoing market volatility. A10's competitive positioning is fundamentally shaped by its technological differentiation. Its product portfolio, encompassing the Thunder Application Delivery Controller (ADC), Thunder Carrier Grade Networking (CGN), Thunder SSL Insight (SSLi), and Thunder Convergent Firewall (CFW), forms the backbone of its secure infrastructure solutions. These are complemented by the A10 Defend security suite, which includes Threat Control, Orchestrator, Detector, and Mitigator, and the intelligent management tool, A10 Control. A key differentiator lies in the solutions' ability to deliver industry-leading efficiency in terms of throughput, low latency, and best-in-class security. For instance, in the context of power-hungry AI applications and data centers, A10's offerings allow customers to achieve better ROI by requiring fewer A10 products compared to competitive offerings, thereby materially reducing power consumption without sacrificing performance. This efficiency is a significant competitive advantage, particularly as customers increasingly prioritize building AI data centers. The company's commitment to innovation is evident in its continuous R&D initiatives. A10 is actively developing new solutions for Bot Protection, advanced DDoS mitigation, and technologies specifically designed for GPU-based AI infrastructure. The integration of AI for predictive analytics into existing solutions and the enhancement of A10 Control for centralized management across all A10 products (including partner products) are strategic priorities. These efforts aim to create an integrated solution that reduces cybersecurity risk, improves user experience, and simplifies IT infrastructure, including AI build-outs. The recent acquisition of ThreatX Protect in February 2025 for $19.6 million in cash further bolstered the A10 Defend portfolio with Web Application and API Protection (WAAP) capabilities. ThreatX Protect is recognized for its ease of deployment and its unique behavioral and risk profiling to protect against evolving threats, including those targeting AI applications, making it an ideal complement to A10's existing AI firewall solutions. This acquisition is a strategic move to enhance A10's relevance in the enterprise vertical and align its roadmap with contemporary API and WAAP security needs. ## Performance and Strategic Execution Across Segments A10 Networks' recent financial performance underscores its strategic execution and the growing demand for its specialized solutions. For the second quarter of 2025, total net revenue increased by a robust 15% year-over-year to $69.4 million, with first-half 2025 revenue reaching $135.5 million, up 12% from the prior year.

Product revenue, a lead indicator for future services growth, surged by 33% year-over-year in Q2 2025 to $39.2 million, and by 26% in H1 2025 to $75.2 million. This significant increase was driven by heightened demand from both enterprise and service provider customers in the Americas and APJ regions, indicating customers are choosing A10 for both new installations and refreshes. Services revenue, while experiencing a slight decrease of 1% in Q2 2025 to $30.2 million and H1 2025 to $60.4 million, is influenced by a shift to longer-term contracts (typically 5 years versus 3 years previously). This spreads revenue recognition over a longer period but significantly increases long-term deferred revenue, which stood at $144.4 million as of June 30, 2025, providing greater visibility into future revenues. Renewal rates on eligible contracts remain strong, exceeding 90%. The company's customer diversification strategy continues to yield results. Service provider revenue accounted for 60% of total revenue in Q2 2025, up from 56% in Q2 2024, growing 24.6% year-over-year to $41.6 million. This segment benefited from improved demand for data center expansions and AI infrastructure investments. While some North American service providers still exhibit caution in CapEx spending, others are returning to more normal spending patterns. Enterprise revenue, representing 40% of total revenue in Q2 2025, grew 4.0% year-over-year to $27.8 million. 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.
