Thank you, David, and good afternoon, everyone. Thank you for joining Certara's third quarter earnings call. John and I will begin with prepared remarks, and then we will take your questions. During the third quarter, our team continued to execute against our 2025 goals, while also positioning Certara for long-term success by investing in our R&D and commercial teams. Third quarter revenue of $104.6 million was in line with our expectations, representing 10% reported year-over-year growth. We outperformed internal profitability expectations, delivering adjusted EBITDA of $35.2 million, representing a margin of 34%. Our team remains focused on investing for growth with R&D up 24% versus the same period a year ago and increasing to 10% of revenue from 9% in the prior year period. On the other hand, third quarter bookings of $96.6 million came in below our expectations, representing growth of 1%. Among our Tier 1 services customers, we observed cautious spending behavior with some customers pushing deal time lines later into the fourth quarter and into 2026. Taking this into account, we are narrowing our revenue guidance to $415 million to $420 million, which we believe reflects the most likely range of outcomes for the year based on our performance to date. We have raised our adjusted EBITDA margin guidance to the high end of our previous guidance range and raised our adjusted EPS guidance to reflect the continuation of outperformance against our profitability targets and the impact of share repurchase activity. We continue to see pockets of outperformance throughout our portfolio, including our Simcyp PBPK software and our QSP services. However, some of our customers are still dealing with factors that impact decision-making time lines and R&D allocation decisions. As large pharma customers adjust focus with their R&D programs and now onshoring initiatives that are impacting personnel and resource allocations, we have seen a slowdown in deal completion time lines, particularly in regulatory services and biosim services. This slowdown has persisted into the beginning of the fourth quarter, conflicting with historical seasonality trends. We are closely monitoring consumer spending patterns as we begin to plan for 2026. At a high level, we continue to see several positive leading indicators for the biosimulation market and for Certara. Among large pharma customers, the use of model-informed drug development is growing throughout all stages of development. Customers are adopting biosimulation solutions for use in dosing, efficacy and toxicity analysis and using the technology earlier as we expand our software capabilities into discovery and preclinical. Among our smaller customers, the adoption of biosimulation is accelerating through the use of our technology-enabled services. As drug developers look to optimize their speed and efficiency, they are often attracted to areas of our business such as QSP, which can help streamline decision-making and trial design in both the preclinical and clinical stages. Since our IPO, we have seen a significant increase in both the number of customers using our products and services as well as the wallet share of Certara within larger organizations. Most of all, we are encouraged by our evolving relationships with key stakeholders and users at customers. Earlier this year, we hosted our second annual Certainty Conference, bringing together hundreds of our users to discuss the future of model-informed drug development. In early October, we held the same conference in Barcelona with our European user base, and the experience was very productive for all parties. At both events, I had the opportunity to discuss Certara's products with customers where they provided feedback on our software, suggested new features and functionality and learned about our new products and long-term vision for the Certara platform. There is tremendous value that can be gained by making more informed decisions earlier in the drug development life cycle, which is why we are moving into discovery and preclinical. We closed the Chemaxon acquisition a year ago in early October of 2024, which gave Certara an established product suite in discovery with synergistic capabilities relative to Simcyp. In the first 12 months under Certara ownership, Chemaxon has continued to grow and is on track to reach corporate average margins by the end of the year. Elsewhere, our services group has grown preclinical work in QSP, especially since the FDA's guidance promoting the use of new approach methodologies. QSP has grown ahead of the rest of the biosimulation business on a year-to-date basis and is becoming an increasingly important part of our business. Now turning to our financial performance. In software, bookings of $40.8 million represented growth of 17%. We saw solid bookings performance in Tiers 1 and 3, which were in line with expectation, while Tier 2 was below expectations, which we attribute more to timing than anything. Software revenue of $43.8 million grew 22% on a reported basis and 6% organically, led by strong growth from Simcyp in addition to $5.6 million of contribution from Chemaxon. In services, bookings of $55.8 million declined 9% on a reported basis, driven by slowness in the Tier 1 customer base. We have continued to observe cautious decision-making among large pharma customers into the fourth quarter. Services revenue of $60.8 million grew 3% on a reported basis and on an organic basis, led by growth in QSP services. On the innovation front, 2025 has been our most active product development year since our IPO. We've embedded artificial intelligence into both our development processes and our products, accelerating the pace of new model creation following our Vyasa acquisition. We launched several major products this quarter. Pinnacle 21 Enterprise, a cloud-based upgrade, improving regulatory data compliance and submission speed. Phoenix Cloud, which transitions our customers from on-premise to Certara Cloud deployment and provides significant upgrades to product functionality; and CertaraIQ, our new software for QSP modeling designed to expand the use of biosimulation across discovery and clinical phases. Early customer feedback on these releases has been excellent, and we're confident they strengthen our long-term software growth engine. Last year, we announced the strategic review of our regulatory services business. To date, we have made significant progress in our evaluation, including dialogue with external parties and significant internal analysis of best practices. As we evaluate our business, we recognize that regulatory writing performance has been inconsistent. Simultaneously, we value the regulatory writing business' ability to generate cash, which we have used to invest in growth and support recent share repurchases. At this point in time, we are in the final stages of our process and intend to share a definitive outcome before the end of 2025. To close, we remain focused on delivering our 2025 plan and entering 2026 well prepared to capitalize on the opportunities ahead. Although we are seeing some variability in Tier 1 services, we are encouraged by the widespread momentum of biosimulation adoption in drug development. I'll now hand things over to John Gallagher to discuss our financial results in more detail.
