Thank you, Ramy, and good afternoon, everyone. Schrödinger had an excellent Q4, which kept a strong 2023. In Q4, we reported record revenue of $74 million, principally driven by software. For the full year, total revenue grew 20%, with bookends of a large contribution to drug discovery revenue from a single milestone payment in Q1, and then several large multi-year software renewals driving revenue growth in Q4. The year was marked by the considerable progress we have made with our proprietary portfolio and the continued development of our technology platform, which is enabling new capabilities for molecular discovery, even as our largest customers increase the scale of their deployment of our current platform. 2023 was also a year of great validation from our co-founded companies, with $147 million distribution from Nimbus boosting our cash flow and gap earnings, and Structure and Morphic significantly advancing their programs during the year. We see multiple avenues to grow our software revenue in 2024 and beyond, and continue to be active in collaboration and partnership discussions with existing and potential new drug discovery partners. Turning to a review of our fourth quarter results, software revenue for the quarter was $69 million, an increase of 44%. The strong Q4 software result reflected the contribution from a number of multi-year, multi-million dollar on-prem software renewals in Q4, as well as some renewals by hosted customers with ratably recognized software purchases. The contribution of these multi-year on-prem renewals in Q4 was significantly greater than the contribution of multi-year renewals in Q4 2022 compared to Q3, software revenue more than doubled, in line with our expectations and consistent with the typical seasonality of large customer renewals. Drug discovery revenue for the quarter was $5.5 million, compared to $9 million in the same quarter of 2022 and $13.7 million in Q3. Revenue decreased in the quarter compared to the prior year based on non-recurring milestones reported in Q4 2022, as well as reduced contributions from the smaller number of active collaboration programs during the quarter. Total revenue was $74 million in the quarter, an increase of 30% compared to Q4 2022, and a 74% increase compared to Q3 2023. The increase was driven by software revenue growth in Q4. For the full year, software revenue was $159 million, an increase of 17.4%, compared to the prior year. The growth was driven by significant increases in our existing customers, including multi-year renewals by large customers in Q4. For the full year, drug discovery revenue was $57.5 million, compared to $45 million in 2022. The increase was driven by progress in our existing collaborations, recognition of some revenue from new collaborations announced in 2022, and accelerated revenue recognition for previously disclosed programs returned to us by our collaboration partners. Total revenue for the year was $217 million, compared to $181 million in 2022. The increase in total revenue was driven by both software and drug discovery revenue growth. I have a little more color on trends in our software business. Throughout 2023, we disclosed that we were engaged in discussions with a number of large customers about stepping up their level of investment into our technology, and we are encouraged that several of them elected to renew at significantly increased scale and value during Q4. Those agreements contributed a substantial portion of the year-on-year reported growth in on-prem software. We view these companies as bellwethers in the industry and are engaged in discussions with other large companies about substantial renewals. At this stage of the year, we do see opportunities for growth from renewals this year, but since a number of our largest customers entered into multi-year contracts in 2023, the contributions from such additional renewals in 2024 is likely to be less than in 2023. We reported that we continue to have four customers with annual contract value of at least $5 million, and the average contract value for customers over $5 million grew significantly to $6.7 million. The number of customers with ACV of at least $1 million has increased from 18 to 27, as more and more emerging companies recognize the value of increasing their scale of adoption. We have disclosed a new key performance indicator of customer retention among customers of at least 500,000 in ACV. Among such customers, the retention was 98% in 2023 and was 100% in 2022. Our net customer retention for customers of at least 100,000 per year was 92% in 2023 compared to 96% in 2022. The decrease was associated with increased consolidation and discontinuation of R&D efforts by some biotech customers in the 100,000 to 500,000 ACV range. This discontinuation rate has been elevated since 2021 and appears likely to remain elevated in 2024. Moving now to expenses. During Q4, the gross margin on our software revenue was 87%. The gross margin performance in Q4 was particularly high based on the strong revenue result in the quarter. The full year gross margin performance was increased by favorable operating leverage and the shift in allocation of our structural biology team from customer-facing projects to internal and collaboration projects. We believe gross margin in future years is likely to be similar to 2023 with some potential variance depending on revenue performance and mix. The cost of delivering our drug discovery revenue in Q4 was $7.9 million and declined compared to $10 million in Q4 2022. For the full year, our cost of drug discovery revenue was $46.5 million compared to $50.4 million in 2022. The change reflects the reallocation of internal resources from collaboration projects to proprietary programs. The positive profit contribution from our drug discovery revenue for the year reflects the benefits of the one-time milestone reported in Q1. Overall gross margin in Q4 was 78% compared to 68% in Q4 2022 based on improved profitability for software and the shift in mix. For the full year, software gross margin was 81% compared to 78% for 2022. Our software gross margin for the year improved due to lower royalty obligations and favorable operating leverage on our fixed costs. Our drug discovery gross margin was 19% for 2023 compared to a loss ratio of 11% for 2022. It reflects the favorable effects of successful progression of our collaboration programs. Our overall gross margin for 2023 was 65% compared to 56% in 2022. The increase was due to the improvement in software and drug discovery gross margin. As a result of the strong revenue and gross margin performance in Q4, our gross profit increased by 49% compared to Q4 2022. For the full year, our gross profit was $141 million compared to $101 million in 2022. R&D expenses were $52 million in Q4 2023 compared to $35 million in Q4 2022. The main drivers of the increase were increased FTE numbers, CRO expenses and technology expenses. Compared to Q3, R&D expenses were 10% higher based on increased allocation of staff and resources to proprietary programs. Higher FTE numbers and increased CRO expenses contributed. For the full year, R&D expenses were $182 million, which was an increase of 44% compared to the $126 million reported in 2022. The increase for the year was driven by the shift in allocation from collaborations to proprietary programs, higher FTE numbers and increases in CRO expenses. As in the recent past, our R&D expenses are approximately balanced between our technology platform and our therapeutics. A significant portion of the increase in R&D investment from 2022 to 2023 has been associated with the progression of our clinical portfolio. We expect R&D expense growth to moderate in 2024. Sales and marketing expense for Q4 was $10 million compared to $9.4 million in Q4 2022. The increase was mainly due to increased staff and associated expenses. Compared to Q3, sales and marketing expense increased by 9% based on headcount and year-end incentive compensation. For the full year, sales and marketing expense was $37 million compared to $31 million in 2022. The increase of 21% was driven by higher headcount and associated expenses, as well as increased travel. G&A expense for Q4 was $26 million compared to $23 million in Q4 2022. The increase is mainly due to high headcount and one-time royalty obligations, partially offset by lower professional services. For the full year, G&A was $99 million, an increase by 9% compared to 2022. The increase is mainly due to high headcount and FTE expenses, as well as royalty obligations partially offset by lower professional services. For Q4, total operating expense was $87 million compared to $67 million in Q4 2022. The increase is mainly due to increases in R&D. For the year, total operating expense increased to $318 million, compared to $248 million in 2022. The increase is mainly driven by R&D. During Q4, our operating cash use was $37 million, and our cash and short-term investments declined by $34 million during the quarter. For the year, operating cash use was $137 million, compared to $120 million in Q2 2022. Our cash and marketable securities balance was $469 million at year-end, compared to $456 million at year-end 2022. During the year, our operating cash use was offset by the cash distributions from our investment in Nimbus and by favorable trends in working capital. Our operating loss for Q4 was $29.6 million, compared to $28.5 million in Q4 2022. Other items and expenses were $1.9 million in Q4 2023, compared to an income of $1.2 million in Q4 2022. Our reported net loss was $30.7 million in Q4 2023, compared to a loss of $27 million in Q4 2022 and a loss of $62 million in Q3 2023. For the full year, other income and expense items were $220 million, driven by the $147 million distribution from our investment in Nimbus, a gain of $53 million in the fair value of our investments and $19.7 million in other income, mainly interest. Our pre-tax income for the year was $43 million, and our tax expense was $2.2 million. Our net income was $40.7 million or $0.54 per diluted share. As we explained previously, we do not expect our profitability in 2023 associated with the Nimbus distribution to persist in 2024. For GAAP reporting purposes, our fully diluted share count at year-end was $75 million, compared to $71.2 million at the end of 2022. Our basic share count increased by 0.8% over the prior year. Looking ahead to 2024, I already highlighted specific outsized top-line contributions in 2023 that we have to grow past this year. We currently expect that software revenue growth for 2024 will be in the range of 6% to 13%. We firmly believe software is a growth business for us, but that growth remains lumpy with outsized contributions from large customers when they renew extended contracts. We have opportunities to significantly increase the adoption of our technology in our large accounts this year, but it is too early to forecast whether they can match or exceed the contribution from such renewals last year. We expect our growth outlook to benefit from the introduction of enhancements and new capabilities to our platform. Our metrics for our accounts of at least $500,000, at least a $1 million and at least $5 million trended positively in 2023, and we expect our revenue to grow in association with further changes in these metrics. While our largest customers are now purchasing significantly more than $5 million per year in software, this level of adoption is only occurring among a relatively small proportion of the population of global biopharmaceutical companies. Emerging biopharma companies are also among our largest accounts. And their relatively high level of adoption of our technology also suggests further opportunity for our commercial efforts in 2024. We expect software revenue in Q1 to be in the range of $33 million to $35 million and expect the distribution of revenue by quarters to be similar this year to that reported in recent years. We expect drug discovery revenue to be in the range of $30 million to $35 million for 2024. Our guidance incorporates uncertainty about the occurrence and timing of development decisions by our collaboration partners and uncertainty about the outlook for progress of programs in our ongoing collaborations. We have taken a cautious approach to including value for new business development activity this year. Although we continue to be actively engaged in discussions about such opportunities with a variety of emerging and global companies. We expect our software gross margin to be similar to our gross margin in 2023 and to vary slightly depending on customer mix and contract type. Operating expense growth in 2024 is likely to be in the 8% range, significantly below the 28% growth in 2023. In 2024, the growth is likely to be mainly for increased investment in R&D, particularly to support our growing portfolio of proprietary programs. We anticipate that our operating cash burn in 2024 will be higher than our cash burn in 2023. Our goal is to reduce our cash burn in 2025 and later years and that reduction will depend on continued growth in our software revenue, realization of value from our proprietary portfolio and continued operating expense and headcount growth discipline. To conclude, we had an excellent fourth quarter and a very strong year at Schrödinger in 2023 with progress in our software business, collaborations and proprietary programs. We realized considerable value from our collaborations and co-founded company investments. And we see opportunities to create even more value from these activities in 2024 and beyond. Our capital allocation is shifting towards our proprietary portfolio and we are excited that the early clinical data from those programs will emerge in the next one to two years. With the industry's leading computational chemistry platform and a growing portfolio of proprietary medicines and investments in co-founded companies and collaborations coming to fruition, the future is very bright for Schrödinger. Now I'll turn the call over to Karen to provide you with an update about our therapeutics R&D activities.
