And thanks to all of you for joining us this afternoon to review Definitive Healthcare Corp.'s first quarter 2025 financial results. On today's call, I'll provide key highlights from our first-quarter performance and provide an update on our progress against our key strategic priorities for the year. Let me begin by reviewing our financial results for the first quarter, which were above the high end of our guidance ranges on both the top and bottom lines. Our total revenue was $59.2 million, down 7% year over year, ahead of our expectations for the quarter due to an outperformance in professional services and more in-period subscription revenue due to deal timing. While we are pleased with our top line results relative to our expectations heading into the quarter, we continue to work through the impact of lower retention rates. Adjusted EBITDA was $14.7 million, which was well ahead of expectations and represents a 25% margin. This performance illustrates our commitment to controlling costs and the scalable nature of our business model. Unlevered free cash flow performance for the trailing twelve months was also strong, with 91% conversion from adjusted EBITDA over that same period. Operationally, I would frame the first quarter as a solid start to the year. We continue to see improvement, with relative signs of strength in new business, particularly with new logo wins. While renewal rates stabilized in Q1, at the same levels observed throughout the second half of 2024, retention rates remain lower than we believe are achievable. New logo activity was solid across all end markets, which demonstrates the ongoing demand from customers for differentiated actionable data. These wins illuminate what most resonates with new customers and will help us build a more repeatable and predictable new business motion over time. In terms of renewals, we delivered on our first goal of stabilization during the quarter. Improving churn remains our highest priority, and each of our strategic priorities for 2025 are expected to benefit renewal rates over time. There is a natural lag between implementing operational changes and observing their positive impact on renewal rates, so it will take time before we expect to deliver consistent improvement, but we remain confident in our operational strategy. As we discussed on our last call, we are mobilizing the entire company towards enhancing our value proposition and performance across four areas of strategic focus: As a reminder, the four key pillars of our platform and value proposition are differentiated data, data delivery and integrations, driving customer success, and enabling our customers' digital engagement with providers and consumers. I would like to take a moment to provide an update on the progress made across each of these focus areas. Let's start with data. This is our North Star and the foundation for the value Definitive delivers for customers. Critical to our differentiated data are the steps we take to ensure our data is of the highest quality, as well as the unmatched breadth and depth of our coverage of the entire healthcare ecosystem. Unlike other solutions in the market, we have built our leading reference and affiliations data by combining the best data from a diverse set of sources. This includes our own proprietary primary research, public sources including government data and websites of healthcare organizations, key opinion leader data, as well as third-party claims data. Together, we use these sophisticated sourcing methods to build differentiated datasets with deep profiles on each provider and the high-quality historical relationships and affiliations. The result is a rich and actionable dataset required by, and specific to, the healthcare market our customers demand to support their need to access, assess and monitor changes in the rapidly evolving healthcare marketplace. This approach offers a significant advantage over claims-derived and model data alone, which will not capture a significant percentage of the facilities. Our complex systematic processes have been built over a decade. We are in the process of expanding, improving and diversifying our data sources and processes to further strengthen and broaden our data quality so we can provide customers with continuous innovation, and to generate increasing value from the Definitive platform they have come to expect and deserve. This will include extending that advantage with modern data science and partnerships. We are confident that this comprehensive approach to data collection and analysis was critical in the analysis that led to our selection as the primary healthcare data partner for the global strategic partnership we announced last quarter. A foundation of differentiated data is ultimately only as good as our ability to deliver that data to customers and seamlessly integrate our first-party data with whatever third-party data sources are relevant to each customer, which leads to our second pillar, that of seamless integration. Seamless integration is the core of our master data management or MDM strategy, which is designed to ensure our customers can leverage the Definitive platform as an essential component of how they solve key business challenges as simply as possible. Master data management in this case is essentially matching and appending data to our unique token, the Definitive ID. So in addition to our historical solutions to provide direct access through our software, our evolution includes customer engagement through both our unified software platform and by leveraging our integration application and APIs that may also include advanced analytics support. In Q1, we saw strong double-digit growth in the number of engagements where we work with clients to integrate our data with their various tools and systems. Historically, we have seen retention rates be approximately 10 points higher when customers and clients integrate Definitive into their other data sources. The key here is that we are adapting to the changing needs of the market by helping customers solve their challenges in the manner that they want to engage. That could be via our software directly, providing simple APIs to our data, or deploying our data science and advanced analytics resources to partner in the development of insights by matching and appending our data with both their first and third-party data sources. And this approach has the added benefit of leading to deeper relationships with our customers, which leads to our next pillar. I'm pleased with the progress we have made in our third pillar, that of customer success. As mentioned last quarter, at the start of the year, we took several steps to streamline and simplify many of our operations to improve our customer engagement, including the creation of a center of excellence for our analytics and data science teams, integrating our customer success and value delivery team, and revamping their comp incentives and hiring a new Chief Customer Officer. I'm pleased to report that we've done an excellent job operationalizing these changes with nearly no disruption to our performance. Our leadership in this area has quickly assessed the organizational needs and taken swift action to address structural needs and reorient our focus on the voice of the customer and retention. A core component of customer success starts with how we sell and onboard our customers, so I am pleased to report we are also making solid progress on refining our go-to-market and customer support engagement models. As discussed last quarter, we are developing a higher-touch service-enabled delivery model for life sciences customers, many of whom have more intensive data requirements and more sophisticated queries. For example, we began working with a biotech company specializing in rare genetic diseases through an analytics partnership with our medical affairs team. Over the past eighteen months, our work has expanded across multiple disease areas and teams. This partnership led them to invite us into a commercial analytics RFP for an expanded indication of their top therapy asset. It's rare for a client to engage the same partner across both medical affairs and commercial functions, which is a testament to our reputation and the value that we bring. In terms of our final pillar, we are making progress on enhancing our digital engagement capabilities for our provider and diversified customers. We believe there is a significant opportunity for the Definitive platform to not be just a data provider, but also a partner that can automatically operationalize the insights customers derive from our data. Importantly, there are multiple ways we can go to market with digital engagement. Our traditional go-to-market motion of selling directly to customers and partnering with agencies who do this work on behalf of our customers. In Q1, we expanded our go-to-market reach with both agencies and customers to directly source their digital activations, signing two leading healthcare advertising agencies in addition to a significant direct deal. Both agencies are currently ramping up, and we expect to see activation in Q2 with momentum continuing to build in the second half of 2025. In our direct selling efforts, we signed a competitive deal with a New York regional health system. The agreement includes consumer audience activation as part of a broader solution spanning population intelligence and campaign management and is an example of the success we intend to drive through this pillar of focus. The common link between these four pillars is our belief that there are a number of ways that we can increase the value we deliver to customers and ensure Definitive is a critical part of their daily business workflows. By focusing on our differentiated data, developing more intimate, flexible customer engagements, and through relentless focus on customer success through all stages of the customer relationship, we believe we will meaningfully improve our retention metrics, leverage our distribution assets to deliver new solutions, establish consistency in our results, and return our enterprise to growth. While Q1 was a solid start to the year, we do have more work ahead of us. As I approach the one-year anniversary as CEO of Definitive, I strongly believe that we have successfully identified the right key areas that need to be improved, we've assembled the right team, and we are moving with velocity to implement our action plans against clearly defined objectives. Notably, we have successfully implemented these changes without disrupting our progress toward stability. As you'll hear shortly, we remain on track to deliver against our full-year financial targets even after taking into account the recent increase in economic uncertainty. This puts us on target to begin generating sequential revenue growth in the near term while continuing to closely manage our cost structure and identify additional ways to drive efficiencies. We are committed to establishing a track record of consistent execution against the targets we've laid out for our investors. With that, I would like to turn the call over to Rick one final time as our CFO and to thank him for many contributions to Definitive over the past four years. He will review our first-quarter results in more detail, and then Casey will provide an update on our second quarter and full-year financial guidance. Rick?
