Omid C. Farokhzad
Thanks, Kelly, and thank you, everyone, for joining us this afternoon. I will begin our call today by providing updates on our business, and I will then turn the call over to David to provide more details on our financial results for the second quarter of 2025 as well as our outlook for the full year. Beginning with Slide 3. Q2 was a pivotal quarter for Seer as we continue to execute with discipline, advance key commercial and product milestones and accelerate the validation and impact of our platform. The Proteograph Product Suite is unbiased, meaning it's inherently untargeted and enables the scientists to view an unprecedented breadth of the proteome from the most abundant proteins to the least abundant proteins. This deep unbiased proteomics platform is based on our proprietary engineered nanoparticles that is core to the Proteograph Product Suite. In the second quarter, we launched the Proteograph ONE workflow, announced a landmark 20,000 sample population scale study with Korea University and continue to build commercial momentum with strong instrument placement and continued traction with our Seer Technology Access Center or STAC. We also saw increased third-party validation through high-impact publications and compelling data presented at major industry conferences. Back in January, we laid out 4 core growth catalysts for 2025, and I'm proud to share that we've delivered progress across each one. We have always believed that our technology would redefine the trajectory of proteomics and make a meaningful impact within the scientific community. We believe our progress in the second quarter is a clear demonstration of this impact. We ended the quarter with $4.1 million of revenue, representing 32% year-over-year growth and a strong balance sheet of approximately $263 million in cash, cash equivalents and investments. We continue to make highly concentrated and impactful investments in R&D to execute on our product roadmap, and we're continuing our share repurchase program as we believe there is a significant dislocation between our core value proposition and what our stock price reflects today. As of June 30th, we have repurchased approximately $20 million of our Class A common shares under our $25 million share repurchase program that was authorized in May 2024, reducing our net total shares outstanding by approximately 13%. We recognize the policy environment remains fluid and continue to closely monitor how emerging U.S. policy development may influence our customer base. Near-term macro pressures, including evolving tariff implementation and continued uncertainty around government funding are likely to weigh on market visibility through year-end. Despite these headwinds our customers are facing, our strong performance in the first half of the year gives us confidence to reiterate our full year 2025 revenue guidance of $17 million to $18 million, representing 24% year-over-year growth at the midpoint. Now I'd like to walk through our recent progress in our core initiatives of validating our platform, enhancing access, driving innovation and enabling larger cohort studies in more detail. Starting with product innovation on Slide 4. This quarter marked a major inflection point for Seer with the launch of our high-throughput Proteograph ONE assay and SP200 automation instrument. This is a transformative step forward, not just for Seer, but for the entire field of proteomics. Our vision is to enable deep unbiased proteomics research at scale. And with this launch, we're empowering researchers to move from poorly powered small studies that may not replicate to larger core studies that are adequately powered to uncover novel biological insights and advance our understanding of human health. With the Proteograph ONE, we've more than doubled throughput to over 1,000 samples per week with an approximately 30% reduction in run time to approximately 4.5 hours compared to Proteograph XT. The Proteograph ONE enables the identification of up to 10x more proteins than traditional mass spec workflows, achieving industry-defining precision. In addition to the performance improvements, we believe our customers could achieve a meaningful reduction in cost per sample for the full workflow. As evidenced by the initiation of multiple large-scale studies that I will expand on shortly, the combination of Proteograph ONE attributes is translating to an increase in the size of the studies that our customers are running, which we believe will be an important catalyst for revenue growth. We also recently launched the Proteograph DIRECT assay, enabling customers to run cell and tissue samples on our SP200 instrument. This assay was introduced in response to the strong demand from customers to use our automated instrumentation on other workflows that don't leverage our proprietary nanoparticles. Proteograph DIRECT streamlines sample prep by drastically reducing manual processing time to just 60 minutes for AV samples without compromising depth or reproducibility. Looking ahead, we plan to continue broadening our menu, expanding the capabilities of our platform and innovating on our workflow to provide the best solutions for our customers. Now moving on to larger cohort studies on Slide 5. Over the last 3 years, Seer has helped redefine deep unbiased proteomics by enabling researchers to move from small-scale studies of tens of samples to those involving up to tens of thousands of samples, which were previously only possible using targeted proteomics approaches. This quarter, we announced a landmark population scale study in collaboration with Korea University, representing the largest deep plasma proteomics study of its kind. This 3-year study intends to identify novel blood-based biomarkers for young adults in their 20s and 30s using samples from 15,000 cancer patients and 5,000 healthy subjects sourced from Korea's leading cancer institutions. Powered by our newly launched Proteograph ONE assay, the SP200 automation instrument and Thermo Fisher's Orbitrap Astral mass spectrometer, this is the first large-scale plasma proteomics studies to leverage mass spectrometry and AI-driven analytics for early cancer detection. Korea University selected our platform for its unique ability to deliver the depth, scale and reproducibility required for such ambitious study. This collaboration highlights our belief that the Proteograph is unlocking the next generation of sensitive, scalable and personalized diagnostics, laying the foundation for earlier interventions and improved outcomes in young adult cancer patients worldwide. Importantly, this follows our announcement on our last earnings call that Discovery Life Sciences, one of our centers of excellence and a leading omics service provider in collaboration with us, secured a significant contract from a new customer to run a 10,000 sample study on the Proteograph Product Suite and the Orbitrap Astral mass spectrometer. Taken together, these population scale studies demonstrate our belief that Seer is uniquely positioned as the only truly unbiased scalable and deep proteomics platform to power the next generation of proteomic discovery. We expect to see a growing number of population skill studies in the near term. Moving on to the validation of our platform on Slide 6. Validation of our technology continues to grow with 52 customer publications, preprints and reviews, many in high-impact journals, highlighting the unique capabilities of the Proteograph Product Suite. This adds to hundreds of abstracts, presentations and talks showcasing our platform's differentiated biological insights. At recent industry conferences, an increasing number of studies further demonstrated the Proteograph ability to generate unique biological insights. At the American Society for Mass Spectrometry, or ASMS, our customers, collaborators and Seer scientists unveiled new data generated from the Proteograph across 14 poster presentations and multiple researchers presented compelling findings from their early access experience with the recently launched Proteograph ONE workflow. Now turning to Slide 7. At ASMS, Dr. Gary Patti, a Professor at Washington University in St. Louis, presented a study using the Proteograph ONE to analyze the plasma proteomes of metabolically healthy lean, metabolically healthy obese and metabolically unhealthy obese individuals. He identified distinct protein signatures in the metabolically healthy obese population, including 3 novel biologically relevant protein biomarkers undetectable by an affinity-based assay. These biomarkers suggested that metabolically healthy obese individuals may buffer oxidative stress better, regulate their glucose levels better and clear more lipids from the plasma compared to the other 2 cohorts. Though a small study, it highlights the Proteograph ONE's ability to uncover novel biology and advance metabolic disease research. Dr. Josh Coon, a Professor at the University of Wisconsin-Madison, presented his findings from the pilot study that validated the high performance of the Proteograph ONE workflow on monkey samples, delivering a meaningful increase in the amount of unique protein groups versus neat methods. Turning to Slide 8. At the third Annual Symposium on Human Proteome and Health in Oxford at the end of June, Dr. Claudia Langenberg and Dr. Maik Pietzner from Queen University of London presented compelling data from 1,500 individuals in the genes and health cohort run on the Proteograph XT. We believe there are 3 key takeaways from the proteogenomics study that highlight the power of the Proteograph platform. First, the Proteograph detected a high number of proteins previously not found using affinity-based methods. Out of the more than 8,000 proteins detected in plasma, over 2,300 of these proteins represented a quote "previously unexplored proteome" unquote, according to study lead, Dr. Maik Pietzner. Second, the Proteograph detected a high number of protein quantitative trait loci or pQTLs that were previously not found by affinity- based technologies. Over 1,200 pQTLs were detected with over half of them not detected to date by studies up to 40x larger. The Proteograph detected 140 of these novel pQTLs in proteins that were measured by affinity-based methods. However, the pQTLs were not detected by these technologies. 690 of the pQTLs we detected were co-localized with strong disease loci from phenotype-wide association studies or PheWAS. Third, the Proteograph uniquely confirmed the absence of some proteins in plasma that had lost their function. These findings demonstrate the Proteograph's ability to generate meaningful biological insights through a superior depth and unbiased approach, most recently highlighted by Drs. Claudia Langenberg and Maik Pietzner in the GenomeWeb webinar. We continue to partner with leading investigators and host webinars that showcase how researchers are using our platform to generate novel biological insights, further strengthening our growing body of evidence and reinforcing Seer as a trusted partner in the proteomics community. Now moving to Slide 9 to take a closer look at the progress with accelerating access to the Proteograph Product Suite. We continue to see strong demand for STAC, which lowers the barrier of adoption of the Proteograph Product Suite. STAC allows a Proteograph user to run samples in their own lab and have Seer run the mass spec or alternatively provides end-to-end services from sample to a proteomics data and analysis. In Q2, over half of our instrument shipments were acquired by customers who had previously accessed our STAC, representing another solid quarter of STAC to instrument conversion. STAC remains a strong revenue contributor as a strategic asset, giving users hands-on experience with the Proteograph and in some cases, leading to in-house instrument adoption. With the increased throughput enabled by the Proteograph ONE workflow, we have expanded STAC's capacity to meet a growing number of demand without additional investments. We look forward to serving more customers as they generate critical data for their ongoing studies. Our strategic instrument placement program, or SIP, remains a key driver of adoption. By leveraging available operating budgets, SIP helps capital-constrained customers, particularly in the current macroeconomic environment, access our technology. Under this program, we loan an instrument to a customer with an upfront purchase of a consumable kits. Our expanded partnership with Thermo Fisher Scientific to co-market and sell the Proteograph Product Suite alongside their Orbitrap Astral mass spectrometer has been progressing well. This powerful pairing enables population scale deep unbiased proteomics for the first time with exceptional robustness and reproducibility. In addition, this partnership further strengthens our commercial reach and makes it easier for our customers to access a seamless end-to-end solution for unbiased proteomics. We've completed training across Thermo Fisher's U.S. and European sales forces and are beginning to see this partnership translate into advanced stage opportunities. We continue to see traction in several regions, and we are actively pursuing additional population scale opportunities together, reinforcing our confidence in the ability of this partnership to drive adoption. I'm deeply proud of the team's execution this quarter as we lay a strong foundation for the rest of the year and beyond. With that, I will now turn the call over to David.
