Thanks, Mark. This is a solid quarter for Ginkgo. Our deal with Google sets us up well to lead in the application of AI to design DNA and proteins. While our deal with Pfizer is a real signal of commercial progress that I'm going to be digging in on a second. So however, I want to address why we're taking down cell engineering guidance. We're building our relationship with you all as a young public company. And so while we want to have ambitious but achievable goals, we also want to update them as the year progresses and tighten ranges as we get close to year-end. So we're revising our guidance on the cell engineering services components of our revenue to $140 million to $145 million, down from $145 million to $160 million. Generally, this is for the reasons I provided on the last call around industrial biotech venture capital drying up, and also -- and reducing the size of programs that we're seeing in that sector as well as our new program counts being lower than hoped for in Q3, which impacts Q4 revenue. Now I do want to spend some time on the program counts being lower because this is a critical metric for us that demonstrates our flywheel spinning up at Ginkgo, we get better with scale. And it's one that I pay a lot of attention to internally here. So we had 21 new programs this quarter, which was less than I hoped to get. But at the same time, our enterprise sales infrastructure is stronger than it's ever been at Ginkgo. And in particular, I want to call out our new program with Pfizer and explain why it's an important demonstration of our commercial capabilities here. So this is a drug discovery deal in mRNA therapeutics. And that's important, first, because drug discovery is a harder sell than manufacturing R&D deals, which is a number of the previous deals we've done in biopharma. And the reason for that is discovery work is more closely held by our customers. Remember, we have to convince customers to outsource work to Ginkgo's platform that they would otherwise do themselves. This is the kind of work that they tend to think they should do themselves, all right? And then secondly, mRNA is a new modality. It's a new type of drug, right? And so it's emerging, it's high tech. And Ginkgo is proving that we can lead, right, because customers have to choose to work with us in an area like mRNA as a general platform. In other words, the same platform that's doing mRNA biotech is doing agricultural biotech. And all this is to say that this is not an easy deal to close, especially with several hundred millions of dollars of potential downstream value attached to it, which is why it's worth pointing out that I wasn't involved heavily in closing this deal nor was Jen Wipf who heads up our commercial team. This really came out of a normal sales process from our commercial and deal teams here at Ginkgo. And this is a big deal because as much as I like to think myself as good at sales, I'm not scalable, okay? Jen is not scalable. Our enterprise sales team is scalable, and the types of deals Ginkgo is doing, involving fees during technical work, plus hundreds of millions of dollars downstream milestones or royalties, are typically negotiated by the CEO and leadership team of a small biotech company if they were partnering with a large biopharma like Pfizer, like that type of deal you see popping up all the time in industry press and so on in the pharma industry. Ginkgo being able to do a deal like that in a routine manner is a huge strategic advantage for the company and the result of great work and team building, led by Jen, who heads our commercial team over the last 2 years to really build an enterprise sales engine here at Ginkgo. So I'm thrilled to see that. And if we hit the high end of our updated guidance of 85 programs, that would work out to 30 new program starts in Q4, which would be a great further signal of how we're scaling this enterprise sales infrastructure, and that's something I'll be watching with the commercial team coming up. Finally, with the updated guidance, we're still looking at 36% to 44% growth in new programs and 32% to 37% growth in cell engineering services revenue over the last year. Scale helps Ginkgo, and so I'm happy to see that rate of growth. Okay. So let's dive in on our 3 strategic topics. So first, I want to share some recent customer case studies, where we apply our AI technology, so you get a little more sense of what we're doing there. Second, we often get asked, actually, get asked a lot about what programs we're most excited about and what programs are most advanced, sort of our program pipeline. I'm not going to pick favorites. But I'm going to share a lot more data around that pipeline, so you get a better understanding of where all those active programs are and just how much diversity there is in those programs. And then finally, I want to share a little more about how we're thinking about the future of our biosecurity business as a defense technology business, as part of national security infrastructure, and how importantly it relates back to cell engineering. Okay. Let's jump in. Okay. So first, I want to talk about how AI fits into the other assets of Ginkgo and show some case studies of its application. So we talked a lot previously about our foundry and code base at Ginkgo. A reminder, our foundry is our automated laboratories here in Boston that generate data at lower costs as they grow in scale, okay? Think like a factory for testing genetic designs. This data is organized into what we call our code base, which is reused across many different customer programs. In other words, we can use data from one project to help speed the development of a second project from a different customer. And this is, again, another important asset that gets better at scale. So what's exciting is that these data assets can also be used to train large AI models that then inform the sort of experiments we should do to better train those very models, okay? That's a very exciting feedback loop, and it's making our models better every day. It's something we've been making good use of at Ginkgo. We did just announce this quarter, our partnership with Google Cloud. That is going to enhance our development efforts here at Ginkgo. And as a reminder, this partnership with Google gives Ginkgo scalable compute capacity and attractive prices to train large foundation models, but it also represents a commitment by Google to fund our model development efforts upon completion of certain milestones. We're already well on our way to building out those models as we have already achieved our first cash milestone in this deal and expected to earn the second in relatively short order. One way to measure making biology easier to engineer at Ginkgo is by reducing the cost to get to a successful result for our customers. And that cost is a function of 3 things. First, the cost per unit operation, right? So this is like the various operations happening in our foundry, and we drive that down through investments in increased scale automation, miniaturization of liquid handling, so we can use less reagents and so on. Second, the number of unit operations that we need per design cycle. In other words, each round of engineering we do, how many -- how much work do we need to do in the factory. And this one is tricky because it requires judgment. Sometimes you want to run a giant campaign or we try tens of thousand designs. And that's the right thing to do, and it's something that Ginkgo can do uniquely because of our scale. And those early large campaigns can really increase how fast you learn. But to the extent that AI models increase the quality of those designs, we could reduce the size of those libraries, which would save a lot of money, and also mean we get more scale out of that automation, right? If you can use less per program, you can do more programs on the same infrastructure. So it's very exciting. Finally, and I think this may be the most important, is the number of cycles that we need to do for a project. Again, the ability to do reinforcement learning from prior results, in other words, take what we learned from something and feed it back into the model is a key part of why customers are working with us. But in certain areas, we've developed so much depth. In other words, we've done enough projects like that, that we can exceed a customer spec in just the first design cycle. And this is really critical to the customer because the number of cycles, reducing that significantly speeds up programs and often customers, especially in biopharma, care much more about speed than they do about budget. All right. So I want to share a couple of case studies that highlight how we're seeing those variables move, right? So the first case study, that's really cool. This is an enzyme engineering program that we started earlier this year. A customer came to us with an enzyme that had been produced for them by another service provider and wasn't sufficient to meet their need in the market. On the left, you can see the various enzyme designs we tested. So that black dot in the middle is the starting sequence. It represents a starting sequence our customer gave us. Dots closer to that are protein sequences that are closer, that are more similar. And the further way you get, the less similar the sequences to the original. And so this is where the combination of AI and our foundry become really powerful. First, we can afford because of the foundry to test much more broadly than is typical. We see over and over again that minor tweaks to an enzyme is not sufficient to get the kind of big step change improvements customers want. So adding -- but adding all that diversity, all that change in the protein is risky, right? Many of -- if you change sequences a lot, they tend to have less success. And so because we can screen enzymes so much more efficiently, we can search that much wider space and find that kind of needle in a hay stack. Second, our AI/ML models are getting extremely predictive. So ultimately, here, we tested a 500-member library comprising both known enzymes in our code base as well as custom-engineered novel enzymes. Each member is represented by a dot on the left. And in the first cycle, we discovered an enzyme that was 21x better than the original from the customer. And the big win here is speed. Yes, we were also able to use a highly efficient workflow with a relatively small library, those 500 members versus, again, sometimes we do tens of thousands in a cycle. But what really unlocked it was improved accuracy of our AI/ML models predicting sequences that would work, far exceeding our customers' expectations in just the first cycle of design. So that's really exciting. The second customer case study is around production rather than optimizing that enzyme. These are a customer that wanted to figure out how to produce a small molecule compound at higher titers, basically, like how much of it you get out of the fermentation putting in this big tank. And they had a goal here to do this over the next 3 to 5 years, which will be important in a second. And so here, we were able to deliver a better outcome than what the customer asked for. Originally, they just wanted us to try a couple of different host strains, and we did it faster and cheaper than they wanted. So on our first experiment, we were able to improve the titer by 12.5-fold. This is what the customer wanted us to get done by the end of the first year, and we did that in the first experiment, and it was building on knowledge that we already had in our code base. So this is less about the AI and more of that we had genetic elements and we knew which ones worked well in this organism, and we could just take them off the shelf. Okay. That's very powerful, again, strength of scale. Because we have that big code base, we could take something off the shelf that another company that didn't have that wouldn't have on the shelf. And then by the end of the program, which only took us 10 months instead of 3 to 5 years, we were able to deliver 50-fold titer improvements, which is almost double what the customer was originally working towards. The second round of improvement was driven by machine learning and driven enzyme improvement similar to the last case study. And again, this is something that makes Ginkgo unique. We draw on a wide range of tools. So in this case, genetic elements off the shelf, as well as protein design enabled by AI, putting those together, gave that outsized outcome for the customer. So these are a couple of examples of how we're integrating our AI tools into customer programs. I cannot emphasize we're just getting started with this. I'm super excited about AI's ability, like I said, in that equation, to improve efficiency of all those different steps, hopefully reducing cost and speeding time lines for customers. Okay. Second topic. So let's take a look at the rest of the pipeline of customer programs. So again, as a reminder, I want to be very clear about this. Ginkgo does not have its own product pipeline. Like I do not have my own drug development pipeline here at Ginkgo. So when I'm saying pipeline, this is a pipeline of customer programs. In other words, we had to negotiate and sign up a customer and get them to outsource this work for us -- to us to get on this program list. In Q3, we had our highest number of active programs on our platform of all time, with pharma making up the largest percentage of those programs. But an additional piece of color I want to give you today is where those programs stand in terms of their maturity. In other words, how are they progressing through the technical work? All right. And again, I'm happy about that pharmaship. I don't want to undersell it. I do think that's really important, especially as industrial biotech has gotten tighter. It's really great to see that. That is, again, a real strength of being a platform, right? If a certain area gets thinner, we can move to areas that have more demand. As long as biotech in general is moving, we've got something to do. Okay. So this is a fun chart to me. As a traditional product-based biotech company would often show a pipeline like this for maybe 5 or 10 drug assets that are sort of moving through preclinical and clinical trials. Here, we have so many of these programs that we can't fit them on 1 slide. This page is just a programs that are over 50% complete. And we'll show the rest on the next slide. This is the point I was making earlier of why I'm still excited to see 21 programs being added in the quarter, even if it was less than we were hoping. It's just a really great amount of scale on a relative basis in the biotech industry. And to give you an overview of the chart, each horizontal bar here represents a program, and the dark portion of the bar, like on the right-hand side, represents the progress made on that program year-to-date as a portion of the total program. And I cannot tell you the number of times we get asked for this. So I'm very happy to be sharing it with all of you. We will try to do this again, if people ask for things, we try to clean it up and get it out there is a good example. So as you can see at the top, there are a number of programs that are at 100%, okay? So that means that Ginkgo's program were concluded on that program in Q3. So we do this again for Q4, it would be gone, right? And on the next slide, you can start to see some of the shift in program mix. So if you -- again, the colors are tricky. But if you look at the colors here, given more of our recent efforts into biopharma, you'll see that a lot, just under half of our newer programs that are early in development are in biopharma. So again, I'm happy to see that. All right. After those programs hit 100%, if they do, and some fail before they do, but if they hit 100%, then the customer -- and the customer chooses to move forward with them, they enter commercialization. And so you can see we have on the bottom 15 programs that are being actively commercialized now, meaning the customer is moving forward with taking them through regulatory like Synlogic in Phase II trials or they're going into scale up, like Centrient. Many customers don't announce this. Again, this is like product development. So it can be held close to the vest, but we've shared a couple where they have. And eventually, that commercialization process finishes. And we have 6 programs that are kind of fully commercial. In other words, they're giving us royalties, or it's equity on a program that the customer has put into the market. So we're very excited to see the pipeline you saw on the last couple of slides, hopefully move into these buckets as the programs get to 100% complete, and we're extra excited to add many more programs to the pipeline in the coming quarters. So we need many more slides. And the scale of all this is what makes Ginkgo special as a platform rather than a product company in biotech. I'm really, really proud of this scale. It's pretty awesome to see it all in one place. Okay. I'd like to cover our last strategic topic for the day, which is about the national security priority that's emerging around biosecurity and Ginkgo's position in this emerging space. So just the past few weeks, have seen a ton of discussion around the convergence of AI and biology. I've linked a bunch here, articles here, which are good reading for those interested in the space. Last week, Anna Marie, our new Head of AI, which is why you got to see Megan at the start of this presentation instead of Anna Marie, and Matt McKnight, the General Manager of our biosecurity business, were in London during the AI Safety Summit to discuss this. And we've been spending quite a bit of time down in Capitol Hill discussing both how to accelerate U.S. leadership in AI in biotech, but also how to advance these technologies responsibly. So while biosecurity needs to exist, irrespective of its potential for misuse by humans. And the reason for this is, whether we do it or not, Mother Nature is throwing off epidemics and pandemics on our own. And so we do need biosecurity regardless for public health. We're seeing that biology is becoming a more clear national security priority with the advancement of AI tools, which is driving more global government focus on what needs to be done to ensure the technology is deployed responsibly. We've seen real momentum in defense technologies recently, I'd say, as a category. And with particular leadership from our Board Chair, Shyam Sankar at Palantir, you can read a really nice blog post of Shyam's link there. There is not yet a defense tech business for biology, but it is increasingly clear that the defense community believes we have a critical gap when it comes to biology. Ginkgo has been building biodefense tools for years now to protect our platform, to respond to COVID in a big way and, more recently, mapping out what a more scalable biodefense ecosystem might look like, which I'll talk about here. Okay. So Ginkgo plays across the tech stack for biodefense, but we see a significant investment and product gap in the area of monitoring and analytics as most of the investment to date has been on this third box at the bottom, response, so things like vaccines and therapeutics. And that's in part because kind of our approach to infectious disease has been, "Wait until it gets out of control and then do something about it." And with -- work hard if we can to put a damper on it, but hey, things are going to happen, and we got to be able to respond after the fact. That's been the overwhelming investment as opposed to prevention and early detection. I think the impact of COVID has changed that calculus. You have countries looking and saying, hey, the national security effects of this mean we can't just let it happen and clean it up afterwards. We need to be able to detect and respond. And you can think about this a bit like cybersecurity, right? Your computer is constantly monitoring for something dangerous, characterizing it, addressing the threat right as it comes about. In biosecurity, we want to do the exact same thing. We want to build that infrastructure to be constantly monitoring leverage AI to reduce the time to threat detection and then mitigation. And it could be even a different kind of mitigation than vaccines. If you detect it early enough, you just snuff it out, okay? So our bioradar product, where we collect samples from wastewater on planes and anonymously from voluntary swabs from passengers on airlines, is exactly the type of infrastructure we're building to do this type of monitoring. This bioradar product enables continuous data collection. So not just on COVID, but we just announced we're expanding to over 30 pathogen targets. We announced an expansion of our partnership with the CDC just this week. Some of these pathogens have actually little to no genetic data publicly available in recent years. So we're really tackling some big blind spots with this expansion into more disease. We're up and running in 9 international airports so far, and that means we're already getting visibility into flights originating from over 100 countries. In addition to airports, we're working in complex zones. And this quarter, we've made a lot of progress with new efforts to monitor agricultural and animal samples from zoonotic spillover, including partnering on 2 new USDA-funded projects. And we're now progressing to deepen our analytical insights by integrating AI-based tools with our bioradar data. And we're examining historical epidemic data and routinely use common AI methods for bioinformatics, genetic engineering detection, I've talked about before, our work with IARPA there, and modeling. And these will continue to get better as our AI platform gets better. But right now, we're really excited to build new prediction capabilities, and we're working with a consortium of partners funded by the CDC Center for Forecasting and Analytics to find new ways to tell when is the disease about to spike? And what measures should you be take -- should be taken against it. And again, I would highlight we already do this sort of thing for weather, right? Like when is that hurricane looking like it's going to come in, right? Like where is it going to land and all that sort of stuff? This is exactly the kind of infrastructure we should have for infectious disease. So all of these data and analytic capabilities are at the foundation of our novel BIOINT so things like biointelligence product for national security as biological risk accelerates and intersects with global conflict and geopolitics, BIOINT will represent a critical component of intelligence capabilities. So this is now things like satellites, okay, yes, they're looking for hurricanes, but they're also looking for missile launches. All right. So we also want to see if someone doing something, some type of misuse, we want to be monitoring to detect that. We're working to build out a BIOINT platform that can support attribution, scenario-based response planning and medical countermeasures. And through this work, BIOINT will be able to address critical questions for security decision makers such as what threats and outbreaks are on the horizon? How dangerous is a new threat? Where does it emerge and how? What can I do about it? And the key here is that last part of what can you do about it, we'll need BIOINT if we want to effectively neutralize biothreats before they cause a lot of damage. It's a lot easier to put out that fire when it's small than when it's too late. All right. Finally, I want to touch on why I think it's so valuable to have Ginkgo's Biosecurity business alongside our Cell Engineering business. These things make sense together. With our bioradar product and BIOINT, we can provide metagenomic data to feed our cell engineering platform. This is more data for training. And the tools we build for understanding biology in our cell engineering platform can be reused to make analytics better on the biosecurity side. Hey, I want to understand what this protein does is a useful thing for cell engineering. It's also useful for an emerging pathogen. Finally, our biosecurity platform could also provide early warning information to help develop new countermeasures, vaccines and therapeutics that our cell engineering platform could help build, right? Our customers develop vaccines and therapeutics, right? So both our biosecurity and cell engineering offerings enable one another, and we believe they'll continue to grow, especially through the use of AI. Okay. In summary, I'm really excited about the great work we've done this quarter, especially the demonstration of our commercial sales engine with the Pfizer program I mentioned and our strategic relationship with Google and AI. And I'm looking forward to continuing our growth in this space. All right. Now I'll hand it back to Megan for Q&A.
