Segment Mix Shift:

Americas continued to strengthen, "reflecting the benefits of A10's investments in our enterprise segment and strength of AI infrastructure build-out" . CFO Michelle Caron noted that "macro-related headwinds, such as persistent inflation and threat of tariffs in rest of the world, were more than offset by strength in Americas" .

Q&A Highlights
The earnings call Q&A provided additional color on key investor concerns:
Service Provider Growth Sustainability: Management noted that while the majority of SP growth came from cloud-oriented companies building AI and cloud infrastructure, traditional telcos also showed improvement in Q3/Q4. The telco investment was twofold: improving security posture for networks and enterprise services, and adding capacity to manage more data, users, and traffic .
Why Specific Guidance Now? When asked why A10 is providing specific revenue guidance for the first time in 2-3 years, CEO Trivedi explained: "As we see the last few quarters... we have continued to make the base of our revenue more durable. And as we are getting more of that from enterprise or large enterprise, as well as SP, as well as AI spending, I think in aggregate, we think we can sustain kind of the momentum" .
APJ Weakness Details: The majority of APJ underperformance was Japan-specific, driven by low GDP growth, persistent inflation, and tariff concerns. Outside of Japan, performance was "close to company average" .
CapEx Increase Explanation: The Q4 CapEx uptick had two drivers: (1) back-end infrastructure investments for the ThreatX acquisition including hosting services, data centers, and SOC capabilities, and (2) early-stage AI infrastructure for customer demos and POCs including "new kinds of processors and chips and GPUs" .
Competitive Wins: In most competitive situations, A10 is displacing incumbents. The exception is security solutions where customers may be implementing new protocols rather than replacing existing vendors .
Agentic AI Discussion: When asked about agentic AI opportunities, management indicated it's early but engagement is focused on helping customers use AI for business goals—particularly predictive analytics and network insights for service providers over the next 2-3 years. They're also working on security posture for new traffic types and low-latency distributed network architectures .
AI-Driven Traffic & Security: On whether AI is driving higher DDoS attack volumes, management said it's "a little early to quantify" but noted that AI facilitates more sophisticated attacks and generates new traffic patterns that didn't exist before: "when people constantly feed prompts and get feedback, as opposed to not having that traffic before" .
