Thank you, Jonathan, and thanks to all of you for joining us this afternoon to review Definitive Healthcare's third quarter 2025 financial results. On today's call, I'll provide highlights from our third quarter performance and an update on our progress against our key strategic priorities for the year. Let me begin by reviewing our financial results for the third quarter, which were at or above the high end of our guidance ranges on both the top and bottom line. Total revenue was $60 million, down 4% year-over-year. This was driven by another quarter of modest year-over-year improvement in renewal rates. Adjusted EBITDA was $18.9 million, representing a margin of 32%, which was $2 million above the high end of our guidance. This reflects continued operational improvements with our focus on maintaining solid expense discipline. There were also some in-quarter benefits that Casey will review in her detailed remarks shortly. We continue to generate solid cash flow, delivering approximately $51 million in unlevered free cash flow for the trailing 12 months. From an operational perspective, Q3 represents another quarter of steady progress. I am pleased to report that we are driving incremental improvement across each of our key strategic pillars and I am encouraged by improvements we are seeing in the data across all of these focus areas. Our new logo production continues to respond the fastest to this attention. Total customer count in Q3 held steady at approximately 2,400. More importantly, our enterprise customer count grew by 10 since last quarter to 520 enterprise customers. This is the highest level we've achieved since Q3 of last year. We believe the improvement in new logos is benefiting from our increased focus on the quality and depth of our differentiated data as well as the intensity we brought to our go-to-market strategy targeting end markets with use cases showing the greatest propensity to invest. Retention rates also had another quarter of year-over-year improvement. While it remains too early to call this trend durable and we still need to get through our large renewal cohort in December and January, we are pleased to see this metric moving in the right direction. This is an encouraging early sign our customers are responding to this attention and we will continue our efforts that will drive continued improvement going forward. Turning to the operational update. I'd now like to provide an update on our 4 strategic pillars, which continue to guide our operational focus and investment priorities. As you'll recall, these pillars are differentiated data, data management and seamless integrations, customer success and digital partnerships and innovation. Starting with differentiated data, which is the foundation of our value proposition. We continue to see validation of our data quality advantage in competitive situations. We are making good progress expanding and deepening our data sets with new sources, including bringing on a new claims data source in Q3 that addresses the data disruption in that market segment over the past year. But we are not satisfied with just returning to previous levels, so we are on track to add another new data source later this quarter that will return DH to above historical data levels. Again, strengthening our data assets are foundational to our business and will be a continued area of investment and focus, including how we expand and enhance our core reference and affiliation data assets. Some wins in the quarter that were driven by our differentiated data include a large multinational biopharma chose Definitive Healthcare to support their Medical Affairs team. Historically, their research to identify key opinion leaders in support of multiple product lines was performed manually. They recognized the value leveraging our solutions and data sets would enable them to more quickly and efficiently identify the right key opinion leaders with which to partner. This is a solid example of how our data solves tangible business challenges and builds a strong position for upselling and cross-selling as we support a future customer need. In another example, a medical device company chose Definitive because their current data provider was lacking critical insights on affiliation hierarchies within integrated delivery networks, which are critical to the effective identification of the correct buying decision makers. Our ability to master complex hospital affiliation data, claims data, contact info and payer mix were key to securing this win. Core to this win was Definitive's ability to leverage and master both our differentiated data with that of third-party data so that the customer could generate highly accurate insights in support of their medical device marketing needs. Turning to our second pillar, that of seamless integrations. We continue to focus on making our data sets, proprietary software and analytical capabilities available to customers in whatever way is most effective and efficient for their business needs. By meeting our customers' needs in the most efficient and effective manner, we enable our customers to more easily leverage our differentiated data through the systems of record and systems of insight of their choice. At the same time, we are making it easier for our commercial teams to win new customers. The easier and simpler we make it to embed Definitive into their workflows and processes, the more this will ultimately improve retention. We know that those customers that have integrated our data directly into their systems renew at significantly higher rates. I would like to add a specific highlight example where we are benefiting from this strategy. We recently signed a 6-figure expansion with a long-time customer who has become a $1 million-plus logo in the diversified market. This customer has steadily expanded their use of Definitive based on our consistent ability to improve the effectiveness of their go-to-market efforts across several of their business units. Our API integration feeds Definitive data directly into their sales force deployment and this tight integration enables their sales teams to efficiently create hierarchies and effectively manage customer contacts. This tight integration has made DH essential to their corporate strategy to leverage data, intelligence and automation to accelerate their revenue growth. Turning to our third pillar, customer success. We continue to receive positive feedback on the steps we've taken in recent quarters to develop a consistent, repeatable and proactive customer engagement process. Our goal is to ensure customers are easily able to generate value from their investments in our solutions as rapidly as possible, and this required us to revisit the entire process starting from the point we initially engage with a prospective customer, how we ensure maximum value is provided through the sales process, and finally, how we onboard and service their solution. It is critical that we ensure the customer receives great experience at integration, and ultimately, we maintain this positive relationship throughout the entire customer journey. This is an iterative process, and we will continue to refine and improve our approach going forward as exceptional customer experience requires continuous focus. As mentioned earlier, we are seeing improvement in retention rates, but we have more objectives to meet before reaching the retention rates we are confident are achievable that will enable us to return to generation of consistent top line growth. The initiatives highlighted earlier all support and contribute to our customer success goals and include a cross-functional effort that spans all functional areas, including sales, support, product and the relentless pursuit of continuous improvement in our core data assets. Looking at our last pillar, innovation and our focus on digital engagement. We are making substantive progress in multiple areas. For example, as part of our efforts to support customers' ad tech efforts, we recently launched our first syndicated always-on go-to-market partnership with LiveRamp, where our data will be available in the LiveRamp marketplace. This will enable marketers to self-serve using prebuilt audience segments or request custom health care audiences from us in support of customers activating verified HCP and consumer data across digital channels in a privacy-safe manner. We also secured another relationship with a significant new strategic partner that is slated to go live at the end of the quarter. While it takes time for these partnerships to begin generating revenue, we are pleased with the progress we are making in building out a broad ecosystem of partners and the validation that their decision to partner with us, Definitive, reinforces in the confidence we have in our approach. We are also seeing good momentum in expanding our agency presence. In Q3, we signed up another 8 agencies. As discussed last quarter, partnering with agencies to ensure we have the opportunity for DH data to power marketing campaigns they run on behalf of our clients is an important part of our digital strategy. Leveraging the most accurate data drives better business performance for customers and makes Definitive an increasingly strategic vendor. So getting our data available to those agencies that support digital engagement is critical. Agency support is only one channel, with another priority focusing on direct sales support. Our commercial teams work directly with customers to support activation campaigns and see some very encouraging results. For example, a large teaching hospital in New England recently expanded from a 5-figure test to a mid-6-figure activation campaign commitment. We believe this is a powerful example of the increased value Definitive can deliver when we give our customers the ability to take our data and close the loop to create augmented, targeted, effective and profitable customer outreach programs. We believe this is a significant opportunity and remains a core area of investment as DH demonstrates we can augment and activate their digital campaigns in a highly effective and seamless manner. Let me wrap up by saying that I am proud of the Definitive team for all the work they are doing to strengthen the value of our data and the solutions they deliver and improve the way we engage with our customers in all phases of our relationship. And we will continue to ensure we maintain vigilance on capital allocation and operational efficiency. As we approach the end of 2025, we are confident that the investments and the changes we are making in the business will position us to deliver improved top line and bottom line performance over time and create value for our shareholders. Now, I would like to turn the call over to Casey to walk you through the numbers. With that, Casey?
