Thank you, Tryn, and thank you everyone for joining us today. 2020 was a breakout year for AbCellera on all fronts. We secured financing, expanded our technology platform, and in December, began trading on the Nasdaq. I'm excited to tell you about 2020 and where we will be going in 2021 and beyond. Briefly, through our work in pandemic response, we proved the power of our technology and our business model, discovering bamlanivimab, the first therapeutic antibody against COVID-19, at world record speed. bamlanivimab was granted emergency use authorization in November and has already been used to treat more than 400,000 patients. At the same time, we continued to invest in our platform and build capacity, including almost doubling our head count and acquiring key technologies, including a proprietary humanized rodent platform and a bispecific engineering platform. We also secured funding for and began work on the build-out of CMC and GMP manufacturing capabilities. Finally, we ended the year with nearly $600 million in cash and over $200 million in accounts receivable. This provides a strong cash position with which we will execute our plan for future growth. Since this is our first earnings call, I'd like to highlight how we are executing on our vision to develop new technologies and new business models that accelerate drug discovery across the industry. AbCellera was founded on the philosophy that pushing back the frontiers of technology is the surest way to transform drug development, and that the impact of these technologies is amplified by business models that are centered around partnerships. Working at the interface of computation, engineering, and biology, AbCellera is redefining the process of how drugs are discovered. We have spent the last nine years building an operating system that can search, decode, and analyze natural immune systems to find rare antibodies that can be developed into treatments. Our unique business model brings our operating system to the industry through partnerships. Over the past six years, we have partnered on over 100 therapeutic antibody discovery programs, working with companies that span the gamut, from early-stage biotech to some of the world's largest and most enabled biopharmaceutical companies. By partnering with AbCellera, these groups can move more quickly, reduce costs, and tackle some of the toughest problems in antibody discovery. Typically, our partners come to us when they have identified a disease target. We then apply our technology to discover high-quality, potent antibodies that are suitable for development, and we return these antibodies to our partners for final pre-clinical development and clinical testing. While our work on COVID-19 has attracted a great deal of attention, the vast majority of our programs are in other therapeutic areas. This includes partnerships in oncology, inflammation, cardiovascular disease, pain, nerve regeneration, and many more. We structure our agreements in a way that aligns our interests with the success of our partners and ultimately with the patients they serve. Our partnership agreements include technical access fees and research payments, clinical and commercial milestones, and royalties on net sales of approved products. It is worth noting that while we work in the biotech sector, we do not consider ourselves to be a biotech company. That is because we are not focused on developing our own pipeline of proprietary drugs through the clinic. We are also not a tools company. We do not sell instruments and devices. Rather, we have established a centralized business model where we invest in teams, technology, and facilities, and provide access to these capabilities through partnerships. By working with others, we believe we can lift up the entire biologics industry. We believe our technology advantage comes from combining three things: proprietary technologies that can generate massive multi-dimensional antibody data sets, custom software systems to aggregate, store, and maintain data, and artificial intelligence and powerful computational tools to extract actionable information from this data. Our stack weaves together proprietary technologies from microfluidics, single-cell analysis, genomics, protein engineering, machine learning, robotics, and automation. Together, these tools provide core functionality to source, search, find, analyze, and engineer therapeutic antibodies. This process generates millions of data points with each program. Our growing data set allows our platform to become more powerful and more accurate with each program. Data generated through our discovery partnerships provides the basis for training AI algorithms that lead to new insights into antibody responses and improve the speed, accuracy, and efficiency of our technology. This creates a positive feedback loop through which each round of data analysis improves the next round of data generation. As we scale our business, this flywheel effect will lead to continuous and accelerating technological advantage. We believe our platform and business model solves two orthogonal technology problems. First, we open up important target spaces that have been outside the reach of legacy technologies. Second, our centralized model democratizes access to these technologies, which enables our partners to start programs without delay and prosecute them at maximum speed. For example, highly enabled companies come to us to help move forward programs that have been stalled for lack of technology. In these cases, we work at the cutting edge of what is possible. This has traditionally been our beachhead market, and where we continue to invest in technologies that we believe can open up large swaths of drug development. On the other side of the spectrum, we partner with smaller companies that typically do not have access to the requisite technology, expertise, and bandwidth to go from idea to a therapeutic lead. For these companies, working with us removes the redundancy of attempting to set up their own discovery capabilities. This empowers them to move programs forward immediately and to focus on the innovation that is novel and unique to them, their target biology, or their unique technologies. As an example of how AbCellera can be the operating system for quickly launching new companies, we recently announced a partnership with Abdera, a precision oncology company working on a class of drugs that use antibodies armed with radioisotopes to destroy cancer cells. As another example, in 2020, we announced a partnership with Invetx, a biotech company at the forefront of developing antibody treatments for companion animals and pets. We subsequently announced an expansion of this collaboration after successfully completing the initial programs. A highlight of our work in 2020 was our response to the current pandemic that led to the discovery of bamlanivimab, the first monoclonal antibody for COVID-19. We believe that this is a time-compressed example of how our technology and business model can bring treatments to patients faster. In March of last year, we mobilized our technology to find solutions for COVID-19. At the beginning of this response, we made a decision to develop a single antibody, emphasizing speed and scalability so that we would be able to help as many patients as quickly as possible. That decision has saved lives. Over the past four months, bamlanivimab has been used to treat approximately 400,000 high-risk COVID-19 patients in the U.S. alone, more than any other COVID-19 therapy in development. We believe this has kept thousands of people out of hospital and has saved thousands of lives. The speed of developing bamlanivimab is a testament both to our technology and to the efforts of all teams involved, including our collaborators at the Vaccine Research Center at the NIH and Eli Lilly. When the entire world mobilized against COVID-19, we started several months after other well-enabled groups. Yet we succeeded in bringing the first monoclonal antibody therapy to the clinic, and were the first to be authorized by the FDA. Today, bamlanivimab has been evaluated both alone and together with other antibodies in more than 5,000 patients across multiple clinical trials and is currently authorized in more than 15 countries. Bamlanivimab alone has been shown to reduce hospitalization by 70% in high-risk patients with early COVID-19 infection and prevent COVID-19 in nursing homes by reducing the risk of contracting the virus by up to 80%. Because of its potency, bamlanivimab also provides a therapeutic backbone for new combination therapies to expand the protection against viral variants. The first of these, bamlanivimab together with etesevimab, has been authorized in the U.S. and within the European Union and is predicted to be effective against 99% of variants currently circulating in the U.S. Recent phase III data show that this antibody therapy reduces COVID-19 related hospitalizations and death by 87%. Most importantly, across all patients treated with antibody therapy in these clinical trials, there has yet to be a single observed COVID-19 related death. I'd like to emphasize that again. Not a single COVID-19 related death has been observed in patients treated with bamlanivimab, either alone or together with etesevimab. In January, it was also announced that bamlanivimab is being evaluated together with VIR-7831 to treat COVID-19 in low-risk patients. Just this morning, top-line data released from the phase II BLAZE-4 trial showed that the two monoclonal antibodies demonstrated a 70% relative reduction in persistently high viral load at day seven compared to placebo. While the speed and manufacturing scalability was the most important criteria early in the response, we anticipated that next-generation antibodies would be needed to combat emerging variants. For that reason, over the past year, we have continued to screen patient samples, identifying thousands of human antibodies and generating massive amounts of information about how the human immune system responds to COVID-19. In January, following the emergence of the South African variant, we screened our human antibody database to find a next generation antibody. In neutralization assays, this second antibody, called 1404, is significantly more potent than any other antibody reported to date, and it's predicted to neutralize all circulating variants, including the South African variant, the U.K. strain, the New York, Brazil, and California strains. In late January, Lilly moved 1404 into preclinical development and manufacturing. We expect it will reach the clinic in Q2 of this year, and have a goal of reaching emergency use authorization by mid-year. Given the breadth and potency of 1404, we believe this antibody has potential to be a best-in-class therapeutic. We also believe antibody therapies are an important complementary approach to vaccines, both now and in the likely scenario that COVID-19 becomes an endemic problem. In summary, over the past 12 months, we've applied our technology to discover what we believe to be the two most potent antibodies against COVID-19 yet reported. We have proven that we are able to respond in real time with solutions that evolve along with the pandemic. Pandemics will happen again, and when they do, we'll be here and we'll be ready. Despite the massive impact of this work, I'd like to emphasize that AbCellera is not a COVID-19 company. In fact, our work in COVID-19 represents only two programs in our portfolio. We have more than 100 programs with a variety of partners that span nearly every indication, and we're just getting started. We see our work in COVID-19 as a proof point of how long-term investments in technology and teams can help make a difference in how new treatments get to patients, and that this is best done in a partnership model. In 2020, we drove several initiatives to further our competitive advantage, including upstream and downstream integration to our technology stack and expanding our capabilities. Our strategy is to continue investing to deepen and expand our technology platform, and in 2020, we made two key acquisitions. The first was OrthoMab, a clinically validated protein engineering platform that allows for any two human antibodies to be recombined into a single molecule that can simultaneously engage with two targets. These antibodies, known as bispecifics, continue to be one of the fastest growing subclasses of biologics. We believe OrthoMab, when coupled with our discovery engine, has the potential to be a best-in-class technology. The second was the acquisition of Trianni. This is a modern version of humanized rodents, which have been by far the richest source of new therapeutics. The Trianni Mouse, the flagship mouse, is one of a very few in the industry that contain all the human genes that have been inserted into the genome in a controlled way. This acquisition is already paying off. It was recently announced that NovaRock Biotherapeutics was granted approval for their phase I study of NBL-012 at the start of this year. This molecule, which was discovered using the Trianni Mouse, is the first from the Trianni platform to enter clinical trial and is the result of work performed by NovaRock through a licensing agreement in early 2018. We plan to use the Trianni platform to do further R&D to bring next generation mice that are suited for generating antibodies against the toughest problems in the industry. We are currently developing four next gen mice and are building up capabilities for additional expansion. We have also licensed access to the flagship mouse to large, well-enabled partners and are continuing to negotiate new licensing deals. We are also excited to make long-term investments in the forward integration of our workflow, which includes the development of translational sciences, CMC, and GMP manufacturing capabilities. We expect that those investments, which will play out over the next two to three years, will allow us to support smaller companies right from target through to IND, all within a single integrated solution. At AbCellera, team is everything. This year, we doubled our team to scale with our business growth, ending the year with 206 employees, up from 107 in 2019. We expect this growth in our workforce to continue through 2021. The work we've done in 2020 provides numerous proof points for our founding philosophy. We believe that by expanding technology capabilities and access, we can help accelerate the development of new therapies to patients and lift up the antibody discovery industry. Over the next few years, we will further extend our technological lead, investing in our platform technology, expanding our capacity with people and facilities, and deepening our relationship across the industry. Before I turn it over to Andrew, I would like to take a moment to acknowledge our team. This year has been unlike any we have ever faced. Your unwavering dedication and courage has made a difference to patients. Thank you all for your work this year. Now I'll turn over to Andrew Booth, our CFO, to provide an overview of our 2020 financials. Thanks, Carl. I'll start by looking at our KPIs. We ended 2020 with 103 programs under contract with 27 different partners. That's a 72% increase in programs under contract as compared to how we had ended the end of 2019. In 2020, we added nine program starts to the cumulative 43 starts we had at the end of 2019. We believe that the lion's share of the economic value in our partnerships is connected with our shared participation in the success of the therapeutics that are discovered by our platform. Since 2018, we have only accepted programs with downstream participation, and in 2020, we actually converted some existing programs without royalties to now include downstream participation as we have expanded our collaboration with certain partners. Looking at revenue in 2020 grew twentyfold over 2019 to $233 million. We had significant royalties and several milestone payments from bamlanivimab in our 2020 results that were not present in 2019. At the same time, our results also reflect the healthy growth of our underlying partnership business. While our business model emphasizes participation in downstream economics, we earned research fees of approximately $20 million, which were attributable to the range of discovery programs we worked on for our partners. This represents 71% growth over 2019. The research fees reflect work on new programs with new and existing partners, as well as activities from ongoing projects. We achieved royalty revenue of $198 million and milestone payments of $15 million attributable to bamlanivimab, achieving milestones all the way from phase I through to first commercial sale by Lilly in the U.S. In terms of bamlanivimab, we are eligible to receive royalties on all sales, whether it is used alone or together with another antibody. We are also eligible to receive royalties on all sales of 1404, whether used alone or together with another antibody following the same economics. Directly attributable to the $198 million in royalty revenue we earned from Lilly's sales of bamlanivimab were $27 million in royalty fees payable to the NIH. The net impact of royalties on income from operations in 2020 was therefore $171 million. This net amount is in line and as expected with our disclosed terms under the agreement with Lilly of royalties in the mid-teens to mid-20s for sales of our COVID antibodies above $125 million. We view these royalties as a non-dilutive source of funding for the company. While we will not be giving forward guidance in the future, given that we're only two days away from the end of the quarter, we can give you some insight into what we are expecting for revenues. Based on the publicly available shipment data of bamlanivimab and calculating our associated royalty, we expect that our first quarter 2021 total revenues will be between $190 million and $210 million. Looking at operating expenses, our operating expenses further reflect the continued investment in our platform and infrastructure to grow our business. Our research and development spend in 2020 was $29 million. We are continuing to expand our R&D team's capabilities and capacity. This allows us to deliver on our partner programs as well as to enhance our technology stack organically. I'd like to call out two expense items in R&D that are not expected to repeat in the future. The first is the expense of $4 million from in-process R&D from the acquisition of the OrthoMab platform for bispecific antibodies. This was an important inorganic move to add to our technology stack's capabilities. The second is an expense for liability classified options, or LCO, related to changing our functional currency to U.S. dollars from Canadian dollars in 2020, where the strike price for options was still in Canadian dollars. This is a non-cash expense that will be settled in equity when employees exercise the associated options. All option holders have since converted strike price to U.S. dollars in the first quarter of 2021, we won't expect to see this expense in the future. We are also extending the reach and capacity of our business development team, as reflected in sales and marketing expenses of nearly $4 million in 2020. This $2.6 million or three times increase was primarily driven by the expansion of the team. It also supported additional marketing and public relations activities. We will continue to invest and grow this function to address the demand that we see from business development. In general and administration expenses for 2020, there were $12 million. The increase from 2019 was driven by strengthening of the team and other activities to support the overall growth of the company and to prepare for being a listed entity. This amount also includes nearly $2 million in costs incurred in connection with our preferred share financing and IPO in 2020. There are three other items on the income statement that I would like to mention. Depreciation and amortization increased by $3.2 million to $4.8 million. That increase is as expected, reflecting the strong investment in the business, including amortization of intangibles related to the Trianni acquisition. Much of the interest in other expense of $6.5 million was incurred in relation to the OrbiMed credit agreement and an earlier credit facility, both of which we retired during the year. We ended the year with no commercial debt. Going forward, we expect interest expense to be nominal given our strong liquidity position and the debt that you see on our balance sheet is from a Canadian government repayable funding program that carries zero interest. Finally, grants and incentives in 2020 saw a $6.5 million increase from 2019 to $8.3 million. This is mostly related to cost recovery from the government of Canada funding our Strategic Innovation Fund, or SIF project. In 2020, we secured total SIF funding of $126 million over five years, which is dedicated to future infrastructure investments, including CMC and small-scale GMP manufacturing capabilities. Any additional cash from the SIF project that we receive for eligible capital expenditure activities will result in the recognition of a deferred credit on the balance sheet for future periods. 2020 was also the first year in which we incurred an income tax expense. In total, our provision for income taxes was $39 million. Looking at net earnings, our net earnings in 2020 jumped to $119 million from a $2 million loss in 2019. This is, of course, in large part due to the success of bamlanivimab. In terms of earnings per share, this works out to a basic earnings of $0.53 per share and diluted earnings of $0.45 per share. Excluding the three non-recurring items I mentioned above, the liability-classified options, the Dualogics IPR&D expense, and financing costs, our basic EPS would have been about $0.60 per share and $0.49 on a diluted basis. Looking at cash, operating activities contributed another $23 million, consistent with the capital efficiency that we have demonstrated in the past. In 2020, we were successful in multiple rounds of financing, raising the net total of $684 million. This includes the $523 million net proceeds from our December IPO, as well as $75 million raised from our Series A-2, and $90 million from our convertible note issuance earlier in the year that supported the acquisition of Trianni. These cash inflows allowed us to make important investments. We successfully acquired Trianni and also made significant investments in facilities and equipment to strengthen our teams and technology platform. We finished 2020 with $594 million of cash and equivalents. Of note, after the year ended, we have received $198 million of accrued accounts receivable balance into cash. Overall, we are now in a strong liquidity position, which will allow us to continue to build capacity, expand platform capabilities, and pursue business development initiatives. With that, we'll now take your questions. Operator? As a reminder, to ask a question, you need to press star one on your telephone. To withdraw your question, press the pound key. We ask that you limit yourself to one question and one follow up, so we have time for all questions in the queue. Please stand by while we compile the Q&A roster. Your first question is from Tiago Fauth with Credit Suisse. Hey, thanks for taking the question, and congrats on the progress. Can you just contextualize historically your presence and efforts in the business development front and now with greater access to capital, how will that move forward? What's your current capacity in terms of new program starts per year? How quickly can that scale up? Perhaps the follow-up to that would be the communications run within investor community. I know a lot of that is out of your hands. It's in the hands of partners. How can investors expect to hear updates on the advancement of the preclinical portfolio and perhaps based on historical rates, what should we expect in the next 12 months or two, three years of programs entering clinic? Thanks. Hello, Tiago. Carl Hansen here. Thank you for the question. There were a few questions wrapped up together there. Maybe I'll answer the last one that you asked, give some background on the business development team, hand off to Andrew in terms of future expectations for business development. Starting with the last part of your question, our business model is predicated on forging partnerships that connect our success with that of our partners. We typically do that by bringing their programs in-house, applying our technology, handing back either hits or development-ready leads. Once we do that, it is within the responsibility of our partners to prosecute those in preclinical development and through the clinic. We collect milestone and royalty payments as those molecules move through development. We typically do not have good insight into the stage of those programs as they reach the clinic. Of course, when they do reach the clinic, and we receive milestone payments, we know the progress, and we will be reporting on those. Coming to the first part of the question, which was about business development activities. In the early years of AbCellera, business development was, I'd say, modestly resourced. That was largely because the company was growing quickly inorganically. Recently, we have changed posture and have begun to build out that business development team. That's included several new hires, and we will be establishing a presence in the U.S. and perhaps also in Europe, in the near term. With that, I'll hand over to Andrew to give some color on the rest of your question. Yeah, just a quick correction. Carl said in the early years, we were growing inorganically, actually. Correct. We were growing organically by driving our own business development. We have expanded the size of the team, really that has been to accommodate the demand that we're seeing. Our business development pipeline, I think, has never been stronger than in the eight-year history of the company. We anticipate, as we have talked about on previous calls, of really making sure we're staffing and resourcing that team appropriately. You talked about capacity there. I just wanted to point out that when you look at the programs we have under contract and then the ones we've started on, it would be a mistake to think that that's a backlog that we're dealing with. It is actually more that we have signed more multi-year, multi-target deals, where it's completely normal to have our customers calling those programs over time and agreeing on a statement of work, arranging reagents, and then for the programs to start. We really view that more as almost sales that we have secured in advance. We have as of yet not been in a position where we did not have capacity in order to start any of the programs that were called. We'll continue to make sure we're making the investments so that's the case. Great. Thank you so much for the answers. Appreciate it. Your next question is from Stephen Willey with Stifel. Yeah, good afternoon. Thanks for taking the questions. Was wondering if you could maybe just provide a little bit more color around LY-CoV1404. Again, I'm not sure to what extent you're constrained in what you might be able to say, but you did highlight the significant increase in potency that you've seen. Just wondering if you could maybe speak to some of the other biochemical properties of the antibody, and I guess I'm specifically interested in whether or not this has been kind of prospectively developed with the intention to make sure that you have a sub-Q administrable product. Thanks, Steve. Carl Hansen here. I'll take that question. 1404, as I mentioned in my prepared remarks, was the result of going back deliberately into a large library of antibodies that we have assembled since the beginning of the pandemic, searching for one that has that rare combination of ultra potency and breadth against all the variants that have emerged. We're at a position now that the pandemic has been going on for one year, and we've got a pretty good idea of what are the most mutated regions of the virus, and ones that have occurred and created an issue with existing therapeutics. 1404 fits that bill perfectly. In our internal neutralization assays, we have benchmarked this against bamlanivimab, which in our hands is the most potent antibody of any that's out there in neutralization assays. It performs superior to that antibody and considerably better than others that are out there. It also, as I mentioned, has very broad reactivity across all the strains that are currently of concern. Given the potency of this antibody, and its behavior thus far in pre-clinical studies, which of course are not finished yet, we believe this antibody has high potential for one that could be administered sub-Q. I'll also note the importance of the potency of that antibody on manufacturing, because, of course, given a fixed amount of manufacturing, the more potent an antibody and the lower the dose that's possible, the more people that can be helped. We're very excited about this molecule. I want to just temper that with a statement that this molecule is still in pre-clinical development, and so until it is in the clinic, and has been tested in patients, we don't yet know its potency, and that's why we need to make sure that those clinical trials proceed as quickly as possible. Understood. That's helpful color. Was just maybe wondering if you could provide a little bit of color with respect to where you are on the litigation with Berkeley, and just whether or not we should be anticipating any kind of material updates there throughout the year. Thanks. Sure. The litigation with Berkeley Lights is proceeding. It's proceeding as expected. We don't have any material updates. Of course, if there are updates, we will be disclosing those to the public. All right. Thanks. Take care of the questions. Thanks, Steve. Your next question is from Gal Munda with Berenberg. Hi there. Thanks for taking my questions. I just have a couple. Maybe if I can just start a little bit about the success you've had over 2020 when you added more than 40 new programs under contract, then in terms of the program starts as well, seeing good progression. Do you have any indication of what we could reasonably expect for 2021 in those fronts? Is that a good way to kind of continue to track progress within the year? I'd say that is the right KPI to be looking at. Again, we have been stressing programs under contract as the leading indicator of the long-term success of the business model. We will be giving those updates as we progress through the year. Once we finalize contracts and agree on a press release with our partner in the ordinary course, we will be issuing press releases accordingly. That would absolutely be the thing to watch out for, Gal. Thanks for the question. Of course, we will continue to, on a quarterly basis, report out with the programs under contract that have been secured for the period that we'll be reporting on. In future earnings releases, we will make sure we highlight those as we go through the year. Carl Hansen here. Just to add one more bit of color on that. I think it is fair to say that the business development pipeline has never been stronger. I believe that that's a combination of the success of the IPO, the profile that we've built with the program on COVID-19, which has underscored the power of the platform, and also with the continual expansion of our capabilities, both through internal R&D and inorganically, and the recognition of that from the industry. We are very bullish on continuing to grow the business. That's really helpful. Thank you. Then just as a follow-up, what I noted effectively, if you look at the number of programs, the number of partners that you've added, that number of programs per partner has increased by about one on average. From almost three to almost four. Is that a trend that you continue to see to expand going forward? Is that a good proof of concept that the partners are adding more programs with you, and that's something that we could continue to expect in the future as well? Absolutely. We're of course, always interested in connecting with new firms, high-quality firms across the entire spectrum of the industry. Through our existing partnerships, when we are successful, we are able to expand those partnerships, as we've done recently, as I mentioned, with Invetx, and we have some other ones that are in discussion along those lines as well. In terms of the numbers, it may not always be the case that the number of programs per partner increases on a quarter-to-quarter basis because of course, some firms have only a small number of programs to do. We absolutely are excited to deepen our interaction with high-quality firms that have the need to build a large pipeline off into the future. Got you. Thank you so much. Appreciate it. Your next question is from Puneet Souda with SVB Leerink. Yeah. Hi, Carl, Andrew. Thanks for taking the question. First of all, congrats on the progress and impact you have made here through bamlanivimab. Just wanted to clarify on project adds or program adds that were in the fourth quarter. Can you just remind us again, what was the exact addition? Also, given Carl's comments about the pipeline has been really strong, maybe can you provide us any sort of metrics? I know in the guide you're providing your revenue guide, but maybe can you provide us any of the, in terms of at least for the first quarter, sort of what sort of a number that we should expect here for in total program adds and how should we think about that number sort of going forward as a metric? Is that a metric that you can provide in terms of the guide? Thanks, Puneet. Carl here. I'll take a first pass at that one. I don't have in front of me the accurate numbers for how many additional programs were added in the fourth quarter of last year, so that's one that I'll have to get back to you on. Andrew may know. In terms of what has happened in Q1 of this year, as I mentioned, we've had strong business development. We're working on several negotiations. The way that our business development cycle normally works is we first engage in a scientific discussion, we ultimately come to terms, and then there is some time involved in contracting. That is unpredictable. We have several contracts right now that are underway, and we will be reporting on those as they are finalized, hopefully, coming up in Q2 here. Okay. In terms of bamlanivimab, I appreciate your providing the guide here for the first quarter. Maybe could you elaborate, maybe Andrew can elaborate on in terms of what's the split in the bamlanivimab royalty versus research programs in the first quarter. Just a quick follow-up on bamlanivimab. Just given what we have seen in terms of the vaccination rates overall improving and also COVID therapeutics combos and cocktails that are being approved here, some of the variants that obviously where bamlanivimab is not effective and some of the impact that we have seen from ASPR with stopping the monotherapy. The key question in the near term is what are the best expectations for bamlanivimab royalty as we go through the rest of the year and with 1404 also adding to that. Maybe just walk us through that, and I know that's not an easy question to answer, but what can you provide us that gives us comfort that the full year at least the Street numbers are numbers that we are comfortable with? Thanks, Puneet, for the question. It's Andrew here. With regards to the Q1 number we gave, seeing as we're only a few days from the end of the quarter, as I mentioned, we've taken the publicly available information from Lilly on the shipments of bamlanivimab, and in terms of the splits, I think you could expect to see it very similar to what we saw in the fourth quarter. If you look at just the Q4 numbers, I think overall our Q1 numbers will look very similar. With regards to the bamlanivimab and its effectiveness against the variants, et cetera, and the remainder of your question, I'll hand over to Carl. Sure. The question was about the prospects for bamlanivimab, in terms of how it will continue to be relevant or important as a therapeutic this year and off into the future. With that, the first thing I'll say is, you did mention the variants that have come up, and it was announced that bamlanivimab as a monotherapy will no longer be sold in the U.S. That is largely because we are shifting over to the combination of bamlanivimab and etesevimab. Shipments of that have already gone out, and of course, the emergency use authorization was granted. That combination currently addresses 99% of the variants that exist in the U.S. bamlanivimab remains a therapy that is being shipped to other countries where they do not have variants that are resistant to bamlanivimab at a significant prevalence. The long-term plan is to also shift those over to combination therapy. 1404, when it comes online, is a very potent and broadly reactive antibody, and one that we expect would be a great candidate to bring into that combination. The ultimate decision of which antibodies to put together, both in clinical trials and ultimately commercially, is one that is being made by Eli Lilly, of course, in close collaboration with us, and it will depend upon how variants continue to emerge out in the market. Out in the world, pardon me. I wouldn't speculate too much on that. In terms of the long-term prospects for bamlanivimab, for 1404, and for antibody therapies in general, we believe that there is a likely scenario that COVID-19 certainly peaks this year, but that it does not go to zero and that COVID-19 becomes an endemic problem for many years. Given the current options that exist for the treatment of COVID-19, a very strong case would be made that if you get sick, you should receive antibody therapy as early as possible. We believe that there will be an important use case, perhaps both in prophylaxis and in treatment of mild to moderate for years to come. We are doing everything we can to bring forward the very best solutions for patients, of which bamlanivimab has already had an impact, and 1404 is our next-generation molecule. Okay. Thank you. Your final question is from Do Kim with BMO. Hi, good afternoon. Thanks for taking my questions, and congrats on all the progress you had last year. I wanted to ask about your 52 cumulative program starts. Could you provide us how many of those programs do you participate in the downstream economics? It looks like from your graph that some of those programs without downstream completed last year. I just want to get a sense of the number of the ones that do participate in the downstream economics. I appreciate that you have limited visibility when your partner takes over the development of a program, but could you tell us how many programs are currently in your partner's hands and past the discovery stage? The contracts that haven't started, what's the gating factor for a partner to move forward and start the program? Thanks, Do. Andrew here. I'll take the start of that question. In terms of the program starts in 2020, how many of them have downstream milestones and royalties or downstream economics? I believe that all of them do in 2020. As I mentioned on the call, in 2018, we stopped executing on contracts that didn't have downstream milestones and royalties. That's not to say there are cases like for Bill & Melinda Gates Foundation, et cetera, where we would do additional programs with them, but we haven't had any of those in 2020. You'll even see that we converted some of the programs which we had previously worked on in a renewal or an increase in the contract or an expansion of the contract that previously did not have downstream milestones and royalties. We even converted them into ones that do have it. Overall, under the 103 programs under contract, 80 of those programs have got downstream milestones and royalties. Really going forward, the program starts will really all be of that variety. You asked, what is the constraint in terms of doing more programs? Normally, in these multi-year, multi-target deals, say an eight-target deal over three or four years, it would be the plan that the customer would be calling two targets a year for us to work on. That's where I say really that 103 programs under contract, that's secured future work for us to do. It's not a backlog. That's how we would be anticipating to take the platform to market, and we will be waiting for the customer to call a target, agree on a statement of work with our R&D team, arrange reagents, and then we would actually start the discovery work on that program. To date, we haven't been capacity constrained, so we haven't been in a situation where a customer has asked us to start and we didn't have the capacity to do so. With our investments, we hope to say that's always going to be the case with building out the capacity and the teams, et cetera, and facilities. The last question that you asked, which was about once we have handed programs off to our customer, how do we get information about their progress through preclinical? I'll maybe pass that over to Carl to give you a bit of color. Yeah. I think that question is close to a question that was asked earlier. It depends on the nature of the relationship. If it's an ongoing collaboration with multiple targets, then it's very likely that we have an ongoing dialogue about the status of molecules as they're moving through preclinical development. That is more and more the case. It wasn't always the case in the early years. When we have insights, then we keep a close eye on that. Of course, again, once molecules reach defined either technical or clinical milestones, then contractually, we get an update on that. To the extent that we can, we will be reporting that back publicly. I just wanted to clarify one of your answers. On the 52 program starts that you have accumulated to the end of 2020, how many of those have downstream participation? Is it 30 out of those 52? Just want to get a number on that. Yeah. From the graph, I think it looks to be about 30, and that sounds about right. I'm looking at the graph as well as you are. That 30, 32, it might be 20 programs that don't, and then the remainder that do, as best I can tell. That's about the ballpark. Okay. A follow-up on the economics that you have with these partners, is there a level of variability of the agreements in terms of the size of the milestone payments and size of the deal? What determines the differences in economics? Is it the indication that these partners are going for, or the partner's requirement of using the full stack of technologies or just part of it? There's several factors. Carl Hansen here. I'll take that one. The first is that it is not the case that every deal is the same. We right-size the terms according to the value that we're bringing to the partner. A few things to sort of add color onto that. Over the course of the last few years, we've seen a trend upwards in terms of the terms, and in particular in the royalties, which we view as the most important part and the most important term in terms of value to us in any agreement. We've also seen differences in terms depending on the class of target or the difficulty of the discovery program. We've worked on, as I mentioned, some of the toughest programs in the industry successfully. That includes targets such as GPCRs and ion channels. Naturally, for those very difficult targets, you would expect that success would be connected to a larger stake in the ultimate development and sales of those products. The other element which you alluded to is as we continue to add technologies, such as the addition of humanized rodents through Trianni, programs that include bispecifics through the OrthoMab platform, and increase both the amount of data and the forward integration of our development, then naturally, we expect that the terms of those deals will reflect that and will move upwards. For all those reasons, we are seeing a growth in the size of business terms and our participation and success. That is one that we keep a close eye on. As I mentioned, for us, the most important of those is, of course, the royalty. Great. Thanks for taking my questions, and congrats again. There are no further questions at this time. I'll turn the call back over to Carl Hansen for closing remarks. Thank you all for joining us today. This is an exciting time for AbCellera, and we are looking forward to keeping you updated on our progress on future calls. Thanks, everyone. Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
