Thank you, David. Good afternoon, everyone. Thank you for joining Certara's Third Quarter 2023 Earnings Call. John and I will start with prepared remarks, and then we will take your questions. In the third quarter, Certara saw sequential improvement and stabilization in overall business trends with bookings growth in both software and services. Total company revenue in the third quarter was $85.6 million of 1% compared with the same period a year ago. Software revenue in the quarter was $31.3 million and grew 10% versus last year and services revenue was $54.2 million and declined 4% versus last year. Over the past several months, we have seen a stabilization in activity across the portfolio, though there are some areas of the business that continue to experience more near-term uncertainty than we are than we are accustomed to. We continue to see strong indications of interest for our biosimulation software and services across all tiers of customers. We are executing well on the operational and commercial plan outlined during the second quarter earnings call. Our commercial alignment is beginning to take form with some early enterprise leads already converting to bookings and revenue across the platform. As we make improvements to operating efficiency of the services organization, we continue to identify best practices, which can be implemented more broadly. We are encouraged by initial progress towards our revised goals for the year, and we remain focused on consistent execution heading into the fourth quarter and into 2024. Our third quarter software bookings were $27.2 million, which represented 7% growth versus the third quarter of 2022. Reported software bookings growth was impacted by the timing of certain renewals with some having booked in the second quarter and some to be booked in the fourth quarter. Software bookings growth was also impacted in our Tier 1 customer segment as a result of industry and macroeconomic headwinds. Despite this, the average software deal size across all customer tiers continue to rise, continuing to grow at double digits. We are encouraged by a return to growth for our bookings among smaller biopharma companies. And we continue to see broad recognition of the value delivered with biosimulation, which instills us with a lot of confidence in future software performance. Throughout 2023, our software team has continued to make progress on key business and product development initiatives. Since its acquisition in 2021, Pinnacle 21 has become an integral part of Certara's software strategy, and we have developed software features that expand upon Pinnacle 21's initial capabilities. Throughout 2023, we have introduced Pinnacle 21's data exchange offering, which helps customers organize and standardize their data from multiple sources using the CDISC standard. We've also introduced automation for the data management and preparation process involved in SDTM formatting, a key component of data submission. Looking ahead, we believe there will be additional opportunities to expand our Pinnacle 21 offering to complement existing applications. We also continue to make progress in advancing biosimulation with the newest addition to Certara's biosimulation software family. We launched Simcyp biopharmaceutics, A version of Simcyp targeted specifically at scientists working on formulation development. This product continues our strategy of expanding biostimulation by releasing tailored tools aimed at specific scientific problems. Additionally, we continue to invest in developing artificial intelligence capability within our existing software platform. Earlier this year, we acquired Vyasa to kick start our AI-enhanced product development efforts. And in early October, we announced the availability of Certara AI. Certara AI is a platform designed to deploy client-specific GPs and to answer in-depth questions throughout the drug development process. Certara AI is unique because it is built using it by assets deep learning algorithm and this data used includes a library of over 60 million life science research documents and the client's proprietary databases, yielding a powerful and proprietary model. One recent advance is our integration of AI in our regulatory writing software, which is called co-author. Co-Author uses artificial intelligence to aid in drafting regulatory submissions. The product can auto populate content, summarize studies, craft messaging and aid the author to deliver the submission. Use of Certara AI and co-author has the potential to drive substantial documentation and writing efficiencies over time. Co-Author, Certara AI and B360 are all examples of products that are either be enhanced or developed using VIASA technology relatively quickly. While it is still the early days in AI, we are very excited about the potential that artificial intelligence and machine learning can bring to Certara products and, in turn, our customers. Shifting now to our technology-driven services segment. Third quarter bookings totaled $57.6 million representing 6% growth compared with the third quarter of 2022. During the third quarter, we observed initial signs of a more stable spending environment among our biopharma customers compared with our second quarter performance. We delivered strong bookings with Tier 3 customers. In addition, services bookings among our tiers 1 customers improved sequentially and grew in the low double digits compared with the prior year period. Following the consolidation of our services business, we are confident the changes being made will improve coordination in operations and commercial efforts. Certara's regulatory bookings improved sequentially, tracking slightly ahead of our revised internal expectations and grew compared with the same period last year. We remain committed to driving improved performance in our regulatory business over the coming months, and we believe the ongoing integration with the biosimulation services business will help improve the pace of performance. Biosimulation services also performed in line with our expectations, and we saw a pickup in customer activity throughout the quarter. Broader industry demand for our services is steadily improving. And our customers continue to see substantial value in our broad offering of biosimulation services. By bringing Certara's expert consultants on board, our clients gain significant value and efficiency for their projects. As we drive the adoption of biosimulation software, we expect to see increased demand for our services, and we are pleased with the current momentum and trajectory of our business. To close, we are confident in our ability to execute on our plan to drive long-term growth in biosimulation. Certara's platform provides a differentiated offering that continues to be prioritized by customers due to the value we can provide in lowering costs and accelerating time lines to drug project completion. As we look ahead to the fourth quarter and beyond, our focus remains on driving consistent execution to best position ourselves for future growth. I now turn the call over to John to review our financial results.
