Thanks, Kevin. Before I get into the quarterly results, I'd like to congratulate Casey on her promotion to CFO. We hired her over a year ago with the view that she would be a successor candidate, and she's been an incredible partner during that time. I'll miss Definitive, but I'm also looking forward to some time off, and I know that I will be leaving you in good hands. Turning to business. I'll start with a detailed review of our Q4 results before finishing with our guidance for Q1 and the full year 2025. In all my remarks, I will be discussing our results on a non-GAAP basis, unless otherwise noted. In Q4, we are pleased to deliver above the high end of our guided ranges for the quarter and for the year. We remain focused on what we can control, and we continue to advance our efforts to operate more efficiently while also delivering innovation for clients. In the fourth quarter, we delivered $62.3 million of revenue, down 6% compared to Q4 2023; $17.5 million of adjusted EBITDA in the period, down 12% from the same period in the prior year. But adjusted net income and non-GAAP earnings per share each grew by 18% and 19%, respectively, over Q4 2023. And we generated $72.5 million of unlevered free cash flow on a trailing 12-month basis, which is up 6% versus the prior year. And for the full year, this resulted in 0.3% revenue growth and a 170 basis point expansion in adjusted EBITDA margin, thanks to cost controls implemented early in the year. Turning to our results in more detail. Revenue for the fourth quarter was $62.3 million, above the high end of our guided range and down 6% from the same period of the prior year. As expected, subscription revenue for the fourth quarter decreased by 4% from the same period of the prior year, while professional services revenue declined more significantly. The key driver of the revenue decrease is that renewal rates are not yet back to our desired levels, especially for our life science customers. We ended the quarter with 519 enterprise customers to find these customers with more than $100,000 in ARR. This was a decrease of 21 enterprise customers year-over-year and a decrease of 11 quarter-over-quarter. These customers represent 68% of our ARR and are a key focus of our go-to-market programs. Our total customer count, which includes smaller customers, was approximately 2,500 at the end of Q4 2024, down about 250 from Q4 of 2023 and down about 70 from the previous quarter as current conditions have disproportionately impacted smaller customers. Net dollar retention for 2024 was 90% for enterprise customers and 85% overall. Adjusted gross profit was $50.3 million, down 10% from Q4 2023. As a percentage of revenue, the adjusted gross profit margin of 80.7% decreased approximately 400 basis points from Q4 2023. This reflects the decline in revenue and the largely fixed nature of most of our costs. Adjusted sales and marketing expenses were $18.9 million, down 7% from Q4 2023. As a percentage of revenue, sales and marketing expenses were 30.4%, about 60 basis points lower than the prior year. For 2025, we expect sales and marketing as a percentage of revenue to increase approximately 150 basis points relative to the full year 2024 as a result of the revenue pressure. Adjusted product development expense was $7.3 million, down 8% from Q4 of 2023. As a percentage of revenue, product development expense was 11.8%, down from 12.1% in Q4 2023. We believe investing in our platform and using both existing and new data sets to launch or enhance multiple products is an efficient and effective way to increase the value we deliver for customers. We intend to continue prudently investing in the highest ROI opportunities on our long-term product road map, and we expect full year 2025 product development as a percentage of revenue to be up approximately 100 basis points compared to the full year 2024. Adjusted G&A expense was $7.7 million, down 10% from Q4 2023. As a percentage of revenue, G&A expenses were 12.4% of revenue, which is an improvement of 60 basis points compared to Q4 2023. We expect G&A expense as a percentage of revenue in 2025 to increase by approximately 100 to 150 basis points year-over-year. Adjusted operating income of $15.8 million was down 14% from Q4 2023. And as a percentage of revenue, adjusted operating income was 25%, down 250 basis points from Q4 2023 due to the revenue pressure in the period. Adjusted EBITDA was $17.5 million, a 12% decrease from Q4 2023. As a percentage of revenue, adjusted EBITDA was 28% of revenue down 190 basis points from Q4 2023, also reflecting our declining revenue. Adjusted net income was $12.6 million or $0.08 per diluted share based on 154.4 million weighted average shares outstanding in the fourth quarter of 2024. Turning to cash flow. Definitive Healthcare's high margins, upfront billing and low CapEx requirements provide substantial free cash flow generation. We focus on trailing 12-month cash flow due to seasonality. Operating cash flows were $58.2 million on a trailing 12-month basis, up 41% from $41.2 million in the comparable period a year ago as we benefited from strong collections and lower deferred commission costs. Unlevered free cash flow was negative $1.6 million in the quarter. This was due primarily to a onetime $10 million CapEx investment made in the fourth quarter related to the strategic data partnership that Kevin mentioned. On a trailing 12-month basis, unlevered free cash flow was $72.5 million, up 6% from the comparable period a year ago, and this is 92% of our TTM adjusted EBITDA of $79.1 million over the same time period. Within the fourth quarter, we repurchased approximately 1.6 million shares at an average price per share of $4.46 for a total of $7.3 million. This leaves $98 million remaining under the existing authorization. At year-end, current revenue performance obligations of $188 million were flat year-over-year as reported, and total revenue performance obligations were up 6% year-over-year. Deferred revenue of $93.4 million was down 4% year-over-year. Subsequent to quarter end, we amended and extended our existing credit facilities. To improve balance sheet efficiency, we reduced the term loan to $175 million and the revolving credit facility to $50 million, and we extended the tenor through January 16, 2030. After completing the transaction, as of January 31, we held $220 million of cash and investments and $175 million in total debt. Additionally, we executed an interest rate cap, protecting us against rate increases if SOFR rises above 4.5% on 80% of the balance of the term loan. If the SOFR rate drops below 4.5%, we would benefit from the lower rate. Full details are available in the 10-K. And then one final bit of accounting before guidance. The recent stock price decline caused us to book a further $97 million goodwill impairment charge as of December 31. And that write-down also generated approximately $11 million of gain on the remeasurement of the TRA liability and a $6 million deferred income tax benefit. As a reminder, these are noncash accounting charges, have no impact on our debt covenants and all impacts are excluded from our adjusted earnings. Moving now to guidance for Q1. After observing the continued pressure on renewals, we now expect total Q1 revenue of $55.5 million to $57 million, a decrease of 10% to 13% year-over-year compared to Q1 of 2024. One important note is that Q1 revenue includes only a partial quarter of revenue from our new data partnership. Although the deal was signed before year-end, the customers access began mid-quarter. In contrast, we will benefit from the full quarterly run rate for the remainder of the year, which we anticipate will improve the revenue trajectory in Q2 relative to Q1. From a non-GAAP profitability perspective, we expect Q1 to be the low point of the year for 2 reasons: first, because we expect to incur a full quarter of the data partnership costs despite only a partial quarter of revenue; and second, as in each Q1, we expect to experience an increase in payroll tax and other benefit costs associated with the start of the year. Taking these factors into account, in Q1, we expect adjusted operating income of $7.5 million to $8.5 million; adjusted EBITDA of $10.5 million to $11.5 million or a 19% to 20% adjusted EBITDA margin in Q1, adjusted net income of $3 million to $4 million or approximately $0.02 per diluted share on 153.3 million weighted average shares outstanding. For the full year 2025, we expect revenue of $230 million to $240 million for a 5% to 9% decline year-over-year. And within the year, we see Q1 as a low point and we expect that year-over-year decreases in revenue will moderate as we move through the year. For the full year, we expect revenue to increase in Q2 relative to Q1, in part due to having a full quarter of the partnership revenue mentioned previously and to increase further before the end of the year due to the seasonality of our professional services business. The high end of our guidance range assumes modest improvements in both renewal rates and sales productivity, thanks to our new data sources and enhanced service approach. While the low end of the revenue guidance reflects a scenario in which renewal rates continue to worsen from the low rates observed in the second half of 2024 while sales productivity trends are similar to those observed in 2024. The total revenue guidance decreases by more than cRPO, primarily because we have taken our recent renewal results into account. Both Q4 and January renewal rates were down year-over-year, and therefore, we assume an NDR in the low to mid-80s in 2025. From a non-GAAP profitability perspective, the largely fixed nature of our cost means that most of that revenue decrease will flow through and create negative operating leverage. So we expect sales and marketing expense of 32% to 33% of revenue, development expense of 11.5% to 12.5% of revenue and G&A expense of 12% to 13% of revenue. Translating that into dollars. In 2025, we expect adjusted operating income of $49 million to $53 million, adjusted EBITDA of $61 million to $65 million for a full year margin of 26% to 28%. Adjusted net income is expected to be between $30 million and $34 million. Earnings per share are expected to be between $0.19 and $0.22 on 153.9 million weighted average shares outstanding. This estimate does not contemplate additional purchases under the existing share repurchase program, but full execution against the remaining authorization would impact 2025 EPS by approximately $0.01. I'd like to reiterate that despite the top line pressures, we remain committed to non-GAAP profitability improvement through the year. We expect Q2 adjusted EBITDA margins to be stronger than Q1 and for adjusted EBITDA margins in the second half to be stronger than in the first half. So in conclusion, we're pleased to have delivered revenue and adjusted EBITDA above the top end of our guidance and increased operating and unlevered free cash flow generation versus the prior year. We remain confident that we're participating in a large and attractive market, and our strategy is designed to improve retention, return us to growth and to increase long-term shareholder value. And with that, I'll turn the call back to Kevin for a few thoughts before we take questions.
