Thank you, Yuka, and thank you all for joining us this morning to go over what was a very strong Q4 and overall a really productive 2025. Let me begin with this quarter's business drivers. We continue to see broad-based positive trends in the demand environment. With the ongoing momentum of cloud migration, we experienced strength across our business, across our product lines, and across our diverse customer base. We saw a continued acceleration of our revenue growth. This acceleration was driven in large part by the inflection of our broad-based business outside of the AI-native group of customers we discussed in the past. And we also continue to see very high growth within these AI-native customer groups as they go into production and grow in users, tokens, and new products. Our go-to-market teams executed to a record $1.63 billion in bookings, up 37% year over year. This included some of the largest deals we have ever made. We signed 18 deals over $10 million in TCV this quarter, of which two were over $100 million, and one was an 8-figure land with a leading AI model company. Finally, churn has remained low, with gross revenue retention stable in the mid to high nineties, highlighting the mission-critical nature of our platform for our customers. Regarding our Q4 financial performance and key metrics, revenue was $953 million, an increase of 29% year over year, and above the high end of our guidance range. We ended Q4 with about 32,700 customers, up from about 30,000 a year ago. We also ended Q4 with about 4,310 customers with an ARR of $100,000 or more, up from about 3,610 a year ago. These customers generated about 90% of our ARR. And we generated free cash flow of $291 million with a free cash flow margin of 31%. Turning to product adoption, our platform strategy continues to resonate in the market. At the end of Q4, 84% of customers used two or more products, up from 83% a year ago. 55% of customers used four or more products, up from 50% a year ago. 33% of our customers use six or more products, up from 26% a year ago. 18% of our customers use eight or more products, up from 12% a year ago. As a sign of continued penetration of our platform, 9% of our customers use 10 or more products, up from 6% a year ago. During 2025, we continued to land and expand with larger customers. As of December 2025, 48% of the Fortune 500 are Datadog customers. We think many of the largest enterprises are still very early in their journey to the cloud. The median Datadog ARR for our Fortune 500 customers is still less than half a million dollars, which leaves a very large opportunity for us to grow with these customers. So we are landing more customers and giving more value, and we also see that with the ARR milestones we are reaching with our products. We continue to see strong growth dynamics with our core three pillars of observability: infrastructure monitoring, APM, and log management. As customers are adopting the cloud, AI, and modern technologies, today, infrastructure monitoring contributes over $1.6 billion in ARR. This includes innovations that deliver visibility and insights across our customers' environments, whether they are on-prem, virtualized servers, containerized hosts, serverless deployments, or parallelized GPU fleets. Meanwhile, log management is now over $1 billion in ARR. This includes continued rapid growth with FlexLogs, which is nearing $100 million in ARR. And our third pillar, the end-to-end suite of APM and DEM products, also crossed $1 billion in ARR. This includes an acceleration of our core APM product, into the mid-thirties percent year over year, currently our fastest-growing core pillar. We have now enabled our customers with the easiest onboarding and implementation in the market while delivering unified deep end-to-end visibility into the application. Now remember that even with these three pillars, we are still just getting started, as about half of our customers do not buy all three pillars from us, or at least not yet. Moving on to R&D and what we built in 2025, we released over 400 new features and capabilities this year. That's too much for us to cover today, but let's go over just some of our innovations. We are executing relentlessly on a very ambitious AI roadmap, and I will split our AI efforts into two buckets: AI for Datadog and Datadog for AI. So first, let's look at AI for Datadog. These are AI products and capabilities that make the Datadog platform better and more useful for customers. We launched the AI SRE agent for general availability in December to accelerate root cause analysis and incident response. Over 2,000 trial and paying customers have run investigations in the past month, which indicates significant interest and showed great outcomes with BCAI. Sorry. And we are well on our way with DeepAI DevAgent, which detects code-level issues, generates fixes with production context, and can even help release the monitor fix. And BigAI Security, which autonomously charges SIEM signals, conducts investigations, and delivers recommendations. The Datadog MCP server is being used by thousands of customers in preview. Our MCP server responds to AI agent and user prompts and uses real-time production data and rich data context to drive troubleshooting, root cause analysis, and automation. And we are seeing explosive growth in MCP usage. With the number of tool calls growing 11-fold in Q4 compared to Q3. Second, let's talk about Datadog for AI. This includes capabilities that deliver end-to-end observability and security across the AI stack. We are seeing an acceleration in growth. Over 1,000 customers are using the product, and the number of spans sent has increased 10 times over the last six months. In 2025, we broadened this product to better support application development and integration, adding capabilities such as experiments, LLM playground, LLM analysis, and custom as a judge. And we will soon release our AI Agents console to monitor usage and adoption of AI agents and coding assistance. We are working with design partners on GPU monitoring, and we are seeing GPU usage increase in our customer base overall. And we are building into our products the ability to secure the AI stack against prompt injection attacks, model hijacking, and data poisoning, among many other risks. Overall, we continue to see increased interest among our customers in Next Gen AI. Today, about 5,500 customers use one or more Datadog AI integrations to send us data about their machine learning, AI, and LLM usage. In 2025, our observability platform delivered deeper and broader capabilities for our customers. We reached a major milestone of more than 1,000 integrations, making it easy for our customers to bring in every type of data they need and engage with the latest technologies, from cloud to AI. In node management, we are seeing success with our consolidation motion. During 2025, we saw an increasing demand to replace a large legacy vendor with stakeout in nearly 100 deals for tens of millions of dollars of new revenue. And we improved log management with notebooks, reference tables, log patterns, calculated fields, and an improved lifestyle among many other innovations. We launched data observability for general availability. Data is becoming even more critical in the AI era. With data availability, we are enabling end-to-end visibility across the entire data life cycle. We launched storage management last month, providing granular insights into cloud storage and recommendations to reduce spend. We delivered Kubernetes auto-scaling so users can quickly identify which over-provisioned clusters and deployments and right-size their infrastructure. In the digital experience monitoring area, we launched product analytics to help product designers make better design decisions with clear data about user experience and behavior. And we delivered run without limits, giving front-end teams full visibility into user traffic and performance, and dynamically choosing the most useful sessions to retain. In security, we are seeing increasing traction in our activity displacing existing market-leading solutions with cloud SIEM in long to private. This year, our engineers shipped many new capabilities, including a tripling of the amount of content packs into the product. And most importantly, the tight integration with Bit.ai security agent, which has already shown promise as a strong differentiator in the market. We launched code security, enabling customers to detect and remediate vulnerabilities in their code and open-source libraries, from development to production. And then we continue to advance our cloud security offering, adding infrastructure as code or IAC security, which detects and resolves security issues with Terraform. And we launched our security graph to identify and evaluate attack paths. In software delivery, in January, we launched feature flags. They combine with our real-time observability to enable Canary rollouts so teams can deploy new code with confidence. And we expect them to gain importance in the future, as they serve as a foundation for automating the validation and release of applications in an AI agentic development world. We are also building out our internal developer portal, which includes software catalog and scorecards, to help developers navigate infrastructure and application complexity, provide rich context to AI development agents, and ultimately enable a faster release cadence. Cloud service management, we launched on-call, and now support over 3,000 customers with their incident response processes. And I already mentioned this AI's already agent, which pairs with on-call to accelerate our customer incident resolution. As you can tell, we have been very busy, and I want to thank our engineers for a very productive 2025. And most importantly, I am even more excited about our plan for 2026. So let's move on to sales and marketing. I want to highlight some of the great deals we closed this quarter. First, we landed an 8-figure annual deal, and our biggest new logo deal to date with one of the largest AI financial model companies. The customer had a fragmented observability stack and cumbersome monitoring workflows leading to poor productivity. This is a consolidation of more than five open-source, commercial, hyperscaler, and in-house observability tools into the unified Datadog platform. That has returned meaningful time to developers and has enabled a more cohesive approach to observability. This customer is experiencing very rapid growth, and Datadog allows them to focus on product development, supporting their users, which is critical to their business success. Next, we welcome back a customer with a European data company in a nearly 7-figure annualized deal. This customer's log-focused observability solution had poor user experience and integrations, which led to limited user adoption and gaps in coverage. By returning to Datadog and consolidating seven observability tools, they expect to reduce tooling overhead, improve engineering productivity with faster incident resolution. They would adopt nine Datadog products as a stock, including some of our newer products, such as FlexLog, observability pipeline, self-cost management, data observability, and on-call. Next, we signed an 8-figure annualized expansion with a leading e-commerce and digital payments platform. These customers' products have an enormous reach in commercial APM solutions, had scaling issues, lacked correlation across silos, and had a pricing model that was difficult to understand or predict. With this extension, they are standardizing on Datadog APM using OpenTelemetry, so their teams can correlate metrics, tracing, and logs to detect and resolve issues faster. And they have already seen meaningful impact, with a 40% reduction in resolution times by their own estimates. This customer has adopted 17 products across the Datadog platform. Next, we signed a seven-figure annualized expansion for an eight-figure annualized deal with a Fortune 500 food and beverage retailer. This long-time customer uses the Datadog platform across many products but still has over 30 other observability tools and embarked on consolidating for cost savings and better outcomes. With this expansion, Datadog log management and flex logs would replace the legacy logging product for all ops use cases, with expected annual savings in the millions of dollars. This customer is expanding to 17 Datadog products. Next, we signed a 7-figure annualized expansion with a leading healthcare technology company. This company was facing reliability issues impacting clinicians during critical workflows and putting customer trust at risk. The customer will consolidate six tools and adopt seven Datadog products, including LLM observability, to support their AI initiative, as well as Big AI SRE agents to further accelerate incident response. Next, we signed an 8-figure annualized expansion, more than quadrupling the annualized commitment, with a major Latin American financial services company. Given its successful tool consolidation projects and rapid adoption of Datadog products across all of its teams, the customer renewed only with us when expanding to additional products, including data observability, CI visibility, database monitoring, and observability pipelines. With Datadog, this customer showed measurable improvements in cost efficiency, customer experience, and conversion rates across multiple lines of business. That proof of value led them to broaden their commitment with us and have firmly established Datadog as their mission-critical observability partner. Last and not least, we signed a 7-figure annualized expansion for an 8-figure annualized deal with a leading fintech company. With this expansion, the customer is moving their log data onto our unified platform, so teams can correlate telemetry in one place and save between hours and weeks in time to resolution for incidents. This customer has obtained 19 Datadog products across the platform, including all three pillars, as well as visual experience, security, software delivery, and service management. And that's it for our wins. Congratulations to our entire go-to-market team for a great 2025 and a record Q4. It was inspiring to see the whole team at our last month, and really exciting to embark on a very ambitious 2026. Before I turn it over to David for the financial review, I want to say a few words on our longer-term outlook. There is no change to our overall view that digital transformation and cloud migration are long-term secular growth drivers for our business. So we continue to extend our platform to solve our customers' problems from end to end across our software development, production, data stack, user experience, and security needs. Meanwhile, we are moving fast in AI by integrating AI into the Datadog platform to improve customer value and outcome, and by building products to observe, secure, and act across our customers' AI stacks. In 2025, we executed very well and delivered for our customers against their most complex mission-critical problems. Our strong financial performance is an output of that effort. And we are even more excited about 2026 as we are starting to see an inflection in AI usage by our customers into the application, and as our customers begin to adopt AI innovation, such as Big AI SRE agent. To hear about all that in detail and much more, I welcome you all to join us at our next Investor Day this Thursday in New York between 1 and 5 PM. I'll be joined by our product and go-to-market leaders, sharing how we are serving our customers, how we innovate to broaden our platform, and how we are delivering better value with AI. For more details, refer to the press release announcing the event or head to investors.datadoghq.com. And with that, I will turn it over to our CFO, David.
