Thanks, Carrie, and thanks, everyone, for joining us this afternoon. We continue to make strong progress across all areas of our business as we ramp our commercial footprint, expand our installed base on the Proteograph Product Suite and work closely with customers and key thought leaders. As the body of data expands to show the power of unbiased plasma proteomics at scale, we're driving our research and development road map to further advance the capabilities of our technology. We ended the second quarter with $3.6 million in revenue and more than $456 million of cash on our balance sheet, continuing to drive momentum in our business while remaining well positioned to execute on our multiyear strategic plan. Now more than 18 months since we started our phased commercialization and six months following broad commercial release, we're seeing accumulation of evidence that our technology addresses significant unmet needs. Across a wide range of research applications, our customers are seeing promising early results that they believe are unlocking biological insights never seen before. We expected that our customers' work would span discovery, translational and clinical research applications, and we are pleased to see an expanding number of customers undertaking projects in translational or clinical research relatively soon after acquiring the technology. To date, the majority of samples run by our customers are in clinical research and involve clinically relevant biomarkers. These projects span a wide range of complex diseases in studies across early cancer detection, biomarker discovery, aging and cell rejuvenation and the impact of environment on human health, among other applications. Now with that larger context, I would now like to share some updates on our execution against our five key objectives to drive growth in 2022 and beyond. As a reminder, these objectives are: first, supporting customers with an industry-leading experience while helping them to systematically scale their use of the Proteograph Product Suite for projects of increasing size and scope; second, expanding our global customer network and installed base of instruments; third, continuing to build out our team, commercial capabilities and geographic footprint; fourth, driving our product road map to enable more applications for our proprietary engineered nanoparticles; and fifth, expanding our partnership efforts to make it even easier for customers around the world and across markets to adopt our technology. Now to the updates. Let's start with how our customers are using the Proteograph and review some specific examples of the progress they're making. In the first quarter of 2022, we saw 11 posters and presentations at scientific conferences. Since then, with the busy spring conference season, our customers as well as Seer scientists have presented 28 posters at nine additional industry events across the United States, Europe and Asia. These events spanned the genomics and proteomics space and included conferences such as AACR, AGBT, ESHG and ASMS. Importantly, about 1/3 of these presentations were from our customers. Now this is pretty remarkable when you consider that most of our customers have had the Proteograph in their labs for a relatively short period of time. For example, at the American Society of Mass Spectrometry, or ASMS, conference in early June, there were multiple presentations and posters featuring the Proteograph Product Suite, including several by our customers. At a high level, the most common themes were, first, the Proteograph Product Suite is enabling an entirely new approach to interrogating the proteome at a depth and scale not previously possible. Second, this capability is allowing researchers to see more of the proteome, especially low-abundance proteins, than they had previously been able to see across similar cohorts. And third, this is enabling researchers to access peptide- and amino acid-level protein variant information, which is necessary to perform high-resolution proteogenomics and only possible through large-scale deep and unbiased proteomics. To illustrate this, I'd like to share some specific highlights from customers' posters. Starting with PrognomIQ, they found novel biological signatures for pancreatic cancer with multiple statistically significant differences in protein abundance among 92 cancer and 104 healthy subjects in a case-controlled multiomic study. This result was very exciting because despite the moderate size of the sample cohort, they achieved a high predictive power driven by their biomarker signatures compared to other pancreatic cancer studies published to date. PrognomIQ observed that the strong detection of changes in biological signals and the breadth of the signals greatly enable identification of novel biological markers in clinical studies of practical size. This is in part due to the low technical noise relative to biological signals that the Proteograph enables across thousands of proteins in the proteome. You can hear more from PrognomIQ on this study also at the upcoming AACR Pancreatic Cancer Conference in mid-September. Moving to Evotec, a Seer center of excellence and one of the global leaders in providing drug discovery solutions on a stand-alone basis or through holistic, fully integrated drug discovery solutions, they presented a poster revealing that, on average, more than 5,000 proteins were detected using the single-shot data independent acquisition, or DIA, analysis across 105 patient samples, with more than 3,000 proteins in individual samples. The poster also highlighted an unprecedented depth of detection for low-abundance proteins such as cytokines, a class of protein known to be increasingly important in development of certain therapeutics, that were previously not accessible in their unbiased workflows at scale. And finally, in a collaboration between Seer, Weill Cornell and SpaceX, the Proteograph was used for deep protium interrogation of the four civilian astronauts from the Inspiration4 crew, looking at time points before and after space flight. The poster showed 50 differentially abundant proteins, primarily indicative of oxidative stress and metabolic pathways. They're excited by these findings, which address the open-ended question of what happens to human physiology at the molecular level as a consequence of space travel. Importantly, the Proteograph provides information as to what protein variance may be affected, by how much, and how this correlates with other omic changes of interest. These posters highlight the unique value proposition of the Proteograph Product Suite to enable access to the vast depth of the protiome which was previously very limited. In a paper published in 2017 titled "Revisiting Biomarker Discovery by Plasma Proteomic" by Professor Matthias Mann, one of the leaders in proteomics, evidence was presented that the majority of the 117 FDA-approved protein biomarkers that were known at the time of their publication were biased towards the most abundant 300 plasma proteins. This is because, historically, these were the proteins that could be readily interrogated at scale using shallow proteomic workflows without the complex immunodepletion and fractionation protocols. The authors proposed that if the proteome could be interrogated to an arbitrary depth of 1,500 proteins efficiently and at scale, an additional 280 protein biomarkers could be discovered and validated. Here is why Seer is uniquely positioned to enable this. The Proteograph enables efficient and rapid access to the plasma proteome with peptide- and amino acid-level resolution at depth and scale never before possible. And the Proteograph provides a high level of reproducibility, enabling discovery power from practical cohort sizes, making it possible to identify even small changes or more complex biomarker signature comprising groups of protein variants across populations. The combination of this depth and scale [indiscernible] would have been made possible in genomics to allow at-scale functionalization of genomic variants and the discovery of novel protein content. Customer data on deep plasma proteomics and the putative biomarkers they are seeing appears to support Professor Mann's hypothesis. Larger cohorts are likely to reveal even more novel biomarkers, finding statistically significant differences in proteins and protein variants. We're in the very early days of this expansion in novel content discovery, and I expect to see a massive deepening of our understanding of the proteome and, thus, biology in the years ahead. As more third-party data enters the public domain over the coming months and years, we expect it will have a network effect in accelerating adoption. We also expect adoption will accelerate across multiple markets in parallel, as we see growing interest in the Proteograph across a broad range of applications, including biomarker discovery, target identification and drug development and early disease infection. This interest spans a broad range of disease families, including neurodegenerative diseases, oncology, cardiovascular disease and other complex diseases, reproductive health, aging and veterinary medicine. It is clear there is a strong need for deep unbiased proteomics, and it's exciting to see the emergence of our customer data and the traction we are progressively gaining. Now turning to our growing installed base. We continue to see strong interest across geographies, with our pipeline of qualified leads roughly equal between academic and commercial customers. As we have previously stated, the sales cycle for our commercial prospect is shorter relative to academic prospects, driven by how each segment receives fundings for their projects. Over time, we do expect the percentage of academic customers in our installed base to increase as more and more grants are submitted and approved for projects leveraging the Proteograph Product Suite. Despite the ongoing risk of COVID and the uncertainty around supply chain, we were able to increase our installed base across North America, Europe and Asia in the second quarter, expanding global access to the Proteograph Product Suite. As an example, Bertis, an innovative South Korean proteomic-based precision medicine company, which recently established a U.S. presence, has added the Proteograph Product Suite to complement and accelerate the discovery and translational mass spec-based clinical test development capabilities by scaling the scope and increasing the resolution of future studies. We are proud of the growing body of customer data and expect to see a number of them submit manuscripts before the year-end. Customer-driven proof points are essential in developing the market for any first-of-its-kind product. We believe that as more third-party data enters the public domain over the coming months and years, the differentiated value proposition of the Proteograph Product Suite to provide novel insight into the proteome and to enable the next generation of multiomic studies will become more established. And finally, we made important progress with our partnership, namely, the Proteogenomics Consortium, which, as a reminder, is a first-of-its-kind partnership that we established with Discovery Life Sciences and SCIEX. This is a multiyear collaboration with three phases for expansion where Discovery will set up, expand and offer deep unbiased proteomic capabilities to their existing and new genomic services customers, with a plan to ramp up to an annual capacity of over 100,000 samples. Discovery recently received the Proteograph and SCIEX's
