Thank you, Kira. I'm excited to be here on my first earnings call as RingCentral's CFO. In my first 90 days, I'm very impressed with the strong prospects and financial profile of the company. From 2021 to 2024, we have tripled our operating profit and grown free cash flow from $80 million to $403 million, representing a CAGR of 72%. During this time, we have returned over 700 million to investors via buybacks plus reduced stock-based compensation driving a basic share count to 2020 levels. Moving to Q4, we delivered strong results with all key metrics above our guidance range and record free cash flows. Total revenue of $615 million, up 8% year-over-year was above our guidance range. ARR increased to approximately $2.5 billion, up 7% year-over-year, up 8% on a constant currency basis. Large steel activity was strong with us signing over $30 million-plus TCV deals with strong RingCX attached. This is a testament to our multiproduct strategy, customers now purchasing more products from us, allowing us to gain a larger wallet share. Our new products are also showing good early traction with our small business customers driving its ARR growth of 7% or 8% on a constant currency basis, which is an acceleration over the last three quarters. Now moving to profitability. I will be referring to non-GAAP results unless otherwise noted. Subscription gross margin was 81%, overall ARPU remained above $30. Please note, we do not intend to share this metric going forward as it is no longer a meaningful indicator of our performance as we transition into a multiproduct portfolio. Operating margin expanded approximately 100 basis points year-over-year to 21.3%, which was above our guidance. This was driven by disciplined spending, especially in sales and marketing and where we expect to drive further incremental improvements. Notably, we also reduced stock-based compensation as a percent of revenue by almost 700 basis points year-over-year as a result of disciplined new grant activity. This, along with improvements in operating margin resulted in us achieving GAAP operating profitability for the second consecutive quarter. Moving to our cash flows and balance sheet. Our strong operating performance, combined with increased rigor and driving efficiencies and working capital improvements resulted in record quarterly free cash flow of $112 million, up 19% versus last year. During the quarter, we also reached approximately 2.2 million shares for $77 million. Now turning to the full year. We delivered another year of strong revenue growth current GAAP operating income positive and reduced our fully diluted share count for the first time in our history. For the full year, we drove meaningful improvement in profitability while continuing to grow. Our 2024 revenue increased 9% to $2.4 billion, operating margin improved by 200 basis points to 21%, and we generated over $400 million of free cash flow, up 24% year-over-year. In addition, we also drove a material reduction in stock-based compensation. SBC as a percent of total revenue declined to 14%, down from 20% in 2023. Moving to our balance sheet, we repurchased approximately 9.7 million shares during the year for $322 million, resulting in the reduction of our diluted and basic share count. Board recently approved an incremental $100 million in share repurchases. This brings total available authorization to approximately $270 million. We also grew EBITDA 17% to $590 million reducing our net debt leverage ratio to 2.2 and 2.6. Before providing guidance, let me share our framework with you. Approximately 85% of our business is UCaaS Consistent with the last few years, we expect to maintain our leading UCaaS market share of approximately 20% based on synergy Research's latest research report. According to IDC, the UCaaS market is expected to grow revenues by about 6% in 2025. With respect to CCaaS, we are seeing strong adoption of our new RingCX product, which is expected to more than double in revenue in 2025. While its aggressive pricing impacts the top line in the near term, it is a higher-margin product and net accretive on a unit economic basis due to our full technology ownership. RingCX is also simpler product and easier to deploy, thus necessitating less professional services. Additionally, we are seeing less hardware phone sales because our app -- production is continuing to take share. Both of these items affect the top line, but not bottom line as they are low margin businesses for us. Regarding capital allocation, we remain committed to delevering the balance sheet and reducing our gross debt to $1 billion by the end of 2026. With this, for the full year, we expect subscription revenue to grow approximately 5% to 7% year-over-year of 6% to 8% on a constant currency basis. Total revenue to grow approximately 4% to 6% year-over-year or 5% to 7% on a constant currency basis. Operating margins of approximately 22.5% representing expansion of approximately 150 basis points. Stock-based compensation of $300 million to $310 million, representing approximately 12% of total revenue, down from 14% last year. The value of net new stock grants are expected to decline about 40% year-over-year, which will result in further SPC declines going forward. Non-GAAP EPS of $4.13 to $4.27, representing approximately 14% growth at the midpoint. Our non-GAAP EPS estimate is based on a fully diluted share count of 93.5 million to 94.5 million. Free cash flow of $500 million to $510 million, up 25% at the midpoint versus 2024. For the first quarter, which has two fewer days than Q4, we expect subscription revenue range of $587 million to $592 million, representing year-over-year growth of 5% to 6% or 6% to 7% on a constant currency basis. Total revenue of $607 million to $612 million, representing year-over-year growth of 4% to 5% on a reported and constant currency basis. Operating margins of 21% to 21.5%. Non-GAAP EPS of $0.93 to $0.97 based on fully diluted shares of $93 million to $93.5 million. Our strong financial profile provides us with many capital allocation options. We plan to generate $500 million of free cash flow in 2025 combined with $350 million of incremental capacity on our term loan A and $225 million on our revolver, we have over $1 billion in available capital. Given our projected internally generated cash flow and external sources of liquidity, we believe we can extinguish our 2025 convertible notes, which we expect to pay off with available cash in the next few weeks and have the capacity to also address the entirety of -- 2026 convertible notes on a timely basis as is contractually required. In summary, let me conclude with four key takeaways. One, we continue leading and holding market share in a mission-critical segment of business voice communications. Two, our new AI products are all growing strong double digits sequentially. Three, our new President and COO, is a proven innovation leader committed to growing our overall TAM. Four, we expect to generate $0.5 billion of free cash flow, which will allow us to reduce debt, repurchase shares and invest heavily into innovation. With that, let's open the call up to questions.
