Good afternoon and welcome to our fourth quarter 2023 earnings call. First, I'd like to welcome two new Board members, Ned Segal and Prat Bhatt, to the RingCentral family. Ned is a seasoned executive with more than 25 years of technology, finance, and capital markets experience including at Twitter, Intuit, and Goldman Sachs. Prat is an accomplished technology industry veteran and financial expert, having served as the Chief Accounting Officer at Cisco Systems for over twenty years. I look forward to working with them both. I also want to warmly thank Allan Thygesen for his nine years of service on our Board, as he will be transitioning off the Board in Q2. Now, moving to our results. We ended the year on a strong note. In Q4, total revenue rose 9%, above the midpoint of our guidance. ARR rose 11% to $2.3 billion. We also achieved record profitability, with quarterly operating margin of 20.5% and free cash flow of nearly $100 million, well above our outlook. Our strong finish to 2023 positions us well to execute on our strategy in 2024 and beyond. I returned as CEO to deliver on our strategy of; one, delivering durable growth and value from our core; two, expanding our TAM by turning RingCentral into a multi-product, AI-first communications leader. To that end, we have recently added three new products to our portfolio; RingCX, our native, AI-first contact center, RingSense for Sales, our conversation intelligence platform for sales professionals, and RingCentral Events, our new virtual, hybrid, and onsite events platform. And three, driving continued robust free cash flow generation, while materially reducing SBC, and maximizing free cash flow per share growth over the long-term. Our right to win is rooted in our industry leading, reliable, global, fully-featured business communication platform that now includes cloud PBX, cloud contact center, and Video meetings, Webinars and Events, all infused with state-of-the-art AI capabilities. As a testament to our industry leadership, in November 2023, RingCentral was named a Leader in the Gartner Magic Quadrant for Unified Communications as a Service Worldwide Report for the ninth consecutive year. And we are excited to report that Aragon Research, an independent third-party research firm, just named RingCX as a leader in the Intelligent Contact Center for SMB. We believe this is a testament to RingCentral's ability to continue delivering a superior, differentiated solution in a competitive market. We are proud to have built a $2.3 billion recurring revenue business that is growing, profitable and serves over 400,000 customers across Enterprise, mid-market, and SMB. Within Enterprise, which we define as customers that generate $100,000 in ARR or more, I am particularly proud to report that this segment has just achieved $1 billion of ARR. This is a major milestone for our company. In fact, in this post-COVID world, Enterprise continues to be a strong growth driver for us. Today, we count almost 20% of Fortune 1000 companies as our Enterprise customers. Amongst these are two of the world's three largest hotel brands, one of the world's largest car rental companies, and many leading Fortune 500 financial services companies. Notably, the majority of our Enterprise customers utilize our solutions integrated with and alongside Microsoft Teams. This strong presence with large customers and within the Microsoft Teams environment is a testament to the trust our Enterprise customers have in our products and our ability to add value to the Teams environment. Our new, advanced integration with Microsoft Teams is a key reason enterprise customers select RingCentral. This includes customers such as Republic Airways, one of the largest regional airlines in the US. Overall, Enterprise continues to be a growth driver for RingCentral, with a positive long-term outlook. Let me now share some additional highlights of why customers large and small continue to choose RingCentral to power their communications. Broadly speaking, customers have historically picked us because of our 99.999% reliability, which we achieved for the 22nd straight quarter, robust feature set, regulatory compliance, and depth and breadth of our integrations. Here are some examples of key large wins and expansions for this quarter. One, a Fortune 100 insurance provider that purchased 20,000 UCaaS seats to connect its distributed broker network made up of thousands of field offices. Another one is a Global 500 retailer that purchased 18,000 UCaaS seats to power communications across its more than 2,000 stores. And finally, a Fortune 500 global healthcare solutions company that added millions of dollars to their existing contract. One of the key integrations for this customer is our reliable and powerful calling capabilities embedded in Microsoft Teams, which they have already deployed to their employees. Their additional spend is a testament to their confidence in our ability to deliver a full communications platform, and add value to the Teams environment. Leveraging our core strengths, we are now expanding into adjacencies such as CCaaS, hybrid, and virtual events, and conversational intelligence for sales. These categories have addressable markets that more than double our current opportunity to over $70 billion, providing multiple vectors for us to drive long-term, profitable growth. Industry analysts and customers alike are already recognizing our ability to deliver in one of our key adjacencies, namely CCaaS. In their latest report, Aragon Research praised RingCX's ability to deliver powerful AI functionality, which includes automated quality management, coaching, and conversation analytics, while being easy to deploy, easy to use, and easy to maintain, and all at a disruptive price point. Regarding customers, we now have over 100 paying RingCX accounts, up from about 50 when we launched in November. These accounts include two Fortune 1000 enterprises who each purchased over 1,000 seats. We also now have hundreds of paying RingSense for Sales customers after having just launched in the second half of 2023. Lastly, approximately six months ago we acquired Hopin's Events business. We are happy with this acquisition and view it as a key addition to our portfolio. Since re-launching as RingCentral Events, hundreds of customers have hosted virtual and hybrid events on this platform in the past few months. This includes many large Fortune 500 companies and well-known businesses such as Spotify, Reddit and HubSpot. We continue to see strong demand for our Events platform. With recent improvements in packaging and pricing and the addition of AI-powered features for Events, we expect to significantly scale this business over time. Notably, we recently won Harvard University over a well-known video-first competitor. Harvard chose us because of our advanced branding capabilities, level of production, and superior attendee user experience. While it is still early for our new products, given the level of traction we are already seeing, we believe we can achieve at least $100 million in ARR from RingCX, RingSense, and RingCentral Events, collectively, by the end of 2025. We expect these new products to be meaningful contributors to our strategy of delivering long-term, profitable growth. Importantly, going forward, our multi-product strategy will be augmented by taking an AI-first approach to everything we do. AI is revolutionizing the way the world works and communicates. The pace of AI innovation in our industry is accelerating. We have a robust roadmap of new AI-based features that should help differentiate our core and new products from the competition. Over the course of this year, we are planning to announce many more AI rooted innovations that will enhance both employee and customer experiences. Stay tuned for some exciting product and innovation announcements at Enterprise Connect at the end of March. We will leverage our broad go-to-market capabilities as we execute on our AI-first, multi-product, strategy. In that vein, I am pleased to welcome Brightspeed, formerly known as CenturyLink, who will join other valuable members of our global service provider family that now includes AT&T, BT, Charter Communications, Telus, and Vodafone, amongst others. Speaking of Vodafone. We started with Vodafone UK and Germany, and in 2023, we expanded with Vodafone into Italy, Portugal, and Spain. And we are super excited about a recent Enterprise win with Vodafone, landing a 15,000-seat deal at Ikea, Germany. And last but certainly not least, profitability. We have greatly expanded our profitability, with operating margins improving from 12% in 2022 to over 20% exiting 2023. We also more than doubled our adjusted, unlevered free cash flow to $325 million for the year. We continue to expect to drive further margin expansion and robust free cash flow generation in 2024 and beyond. Another important factor in creating shareholder value is minimizing SBC. I, and our entire senior management team and the Board, are laser-focused and committed to delivering meaningful improvement in 2024 and beyond. Sonalee will provide more color shortly. In closing, we exited 2023 as a stronger, leaner, more profitable business, and we're well on our way to becoming an AI-first, multi-product portfolio company. Our opportunity is large, our strategy is clear, and we are heads down executing. I am optimistic about our future and am happy to be back at the helm leading RingCentral's next chapter. With that, thank you and let me turn the call over to Sonalee.
