Thanks, Tony, and thanks, everyone, for joining our call this afternoon. We're pleased to report a solid Q3 with continued momentum in bookings, highlighted by enterprise AI bookings growing more than 80% year-over-year, contributing to healthy improvements in backlog. Subscription revenue, which makes up 81% of total revenue, grew 10% year-over-year, primarily driven by enterprise AI revenue growing 41% year-over-year in the third quarter. In terms of profitability, adjusted EBITDA grew 37% year-over-year to a margin of 25%. We also generated record free cash flow, which grew 84% year-over-year to a margin of 13%. The meaningful increase in profitability and cash flow is driven by the transformation initiatives we announced earlier this year. We continue to take action to drive operational improvements while investing in AI and go-to-market initiatives, maintaining a line of sight to our 2027 medium-term targets as we work toward the Rule of 40 and beyond. Turning now to our business updates. Today, I'd like to focus my commentary on 3 key areas. First, our significant and evolving market opportunity ahead. Second, how we believe we're uniquely positioned to win in this new market of AI-powered CX; and third, our momentum with strategic partners. We are in the early innings of an industry shift in CX, where our market opportunity is being driven by multiple growth vectors. For instance, Gartner forecasts the market for traditional CCaaS to grow at a 9% CAGR and the GenAI customer service market to grow at a 34% CAGR through 2029 to a combined annual spend of $48 billion. We believe this growth will create a powerful tailwind for category leaders like Five9 as we continue to execute against this durable multiyear opportunity. Furthermore, we believe Five9 is uniquely positioned to be the platform for orchestrating end-to-end customer experience across both AI agents and human agents. At the heart of our advantage is data. The contact center holds a brand's richest customer data, the full conversation history across every channel and every interaction. Our platform essentially remembers everything a customer has said, whether they spoke with a live agent or an AI agent through voice or digital. This creates what we call a relationship-based experience like when your favorite app [ reaches ] you by name, remembers your preferences and picks up exactly where you left off. Every engagement feels personal, contextual and connected. AI point solutions can't replicate that because they only see isolated transactions, not the full relationship. At its core, our platform is a real-time orchestration engine for every interaction across all channels, whether handled by a human agent or an AI agent. In addition to our suite of AI products, which you're all familiar with, we also infuse AI within our core platform. For example, we now have AI-based routing, which leverages AI to dynamically manage and route every interaction with context to the best human agent or AI agent regardless of channel. Additionally, our platform is uniquely positioned to deliver experiences that will allow human agents and AI agents to collaborate in real time. This can include experiences such as in queue self-service, where during a time a customer waits in queue for a live agent, an AI agent can proactively help resolve the issue, turning hold time into resolution time. Also, agent sidebar, where AI agents can quietly consult a human agent mid conversation to get help without interrupting the customer and AI barge-in, where a human can seamlessly step into an AI interaction to ensure the issue is resolved and the experience remains positive. These experiences showcase what only an end-to-end AI-powered CX platform can deliver. A continuous collaboration between human agents and AI agents, where each interaction enriches the next. That feedback loop compounds over time, creating a powerful data flywheel that strengthens performance, accuracy and personalization. In addition, we're being recognized by industry analysts for our platform-driven approach. For example, Five9 was named a leader in the 2025 Gartner Magic Quadrant for CCaaS for the eighth year, and we were also named a leader in IDC's inaugural MarketScape for European CCaaS. Analysts are recognizing us for strengths in our AI capabilities, cloud-native architecture, global scalability and strong European market presence. This dual recognition validates our strong market position, innovation and consistent customer satisfaction. These platform advantages are also driving momentum with our strategic partner ecosystem, including a major milestone we achieved in the third quarter. In September, we launched Five9 Fusion for ServiceNow, a turnkey AI-powered integration that unifies voice and digital interactions through real-time transcription and intelligent routing. This launch delivers 2 key capabilities. First, our transcript stream integrates directly with ServiceNow Workspace, enabling Now Assist to generate AI-powered summaries and resolution notes that dramatically reduce handle times. And second, our routing engine now directs ServiceNow digital channels and cases alongside Five9 channels for true omnichannel orchestration. This represents a significant milestone in our 8-year partnership with ServiceNow, and they're leaning in stronger than ever, demonstrated by our year-to-date ACV bookings with ServiceNow quadrupling with even greater acceleration in this third quarter. We are also seeing strong traction with other key technology partners, including Salesforce, where year-to-date ACV bookings grew more than 60% and Google Marketplace, where our pipeline has tripled since the announcement of that partnership in Q1. Our strategy of building meaningful partnerships remains a key strength as our long-standing alliances with key partners continue to differentiate us in the market. Additionally, we're seeing ongoing momentum, particularly upmarket, where enterprises are looking to create holistic customer experience strategies that seamlessly integrate with their core business systems. In conclusion, we're optimistic about the foundation we are building for the next decade. At our upcoming CX Summit, we will be announcing new innovations that we believe will set the stage for the next wave of growth as we continue to lead the AI-powered CX revolution with our end-to-end platform to orchestrate interactions across the continuum of AI agents and human agents to deliver what we call the New CX. Importantly, we're doing so with a balanced approach by driving operating leverage and investing in what we believe are the highest return opportunities to drive innovation and durable growth for our business. I want to thank our team of Five9ers for their unwavering dedication to strengthening our leadership position. I'm extremely excited about the future of Five9 and confident we have the platform and the expertise to drive long-term growth. Before turning it over to Andy, I'd like to provide a quick update on our CEO search. As you know, we're focused on identifying a leader with experience and a proven track record in product innovation, a commitment to operational excellence at scale and a growth mindset to further capture market share in this expanding TAM driven by AI. I'm pleased to report that the search is progressing well with our ongoing goal of announcing a successor by year-end. And with that, I'll turn it over to our President, Andy Dignan. Andy, go ahead.
