Thanks, Carrie, 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 Q1 of 2024 and our outlook for the year. We remain incredibly bullish on the potential of our technology to transform our understanding of the proteome. Proteograph data produced and presented by our customers is truly outstanding, and we fundamentally believe in the long-term value of our differentiated technology. However, the pace of adoption and utilization of the Proteograph platform is not yet on track with our expectations. As we have previously stated, an important factor to driving adoption and utilization is a demonstration of the biological insight provided by the Proteograph in the form of peer-reviewed publications from our customers. To that end, we've had several important papers published in the recent months and have a strong pipeline of customer publications that will be forthcoming in high-impact journals throughout the year. Q1 revenue came in at $3.1 million, as we continued to experience headwinds to adoption of the Proteograph Product Suite, in large part due to the elongated sales cycles from the possibility of publications as well as ongoing macro challenges. Given our performance in the Q1 and the current pace of adoption, we now expect 2024 revenue to be in the range of $16 million-$18 million. Until we see an inflection in revenue, we're focusing our resources on our commercial organization while reducing our cash burn to preserve our strong balance sheet. In line with the strategic direction, we're taking the following actions. First, we're continuing to invest in and expand our commercial team to ensure we have the right people in place to drive adoption, education, and awareness of the Proteograph Product Suite. Second, we're launching an additional Seer Technology Access Center located in Europe, providing end-to-end services from sample to data for our European customers. Third, we're implementing an approximately 10% reduction in force outside of our commercial organization to further reduce our use of capital until adoption and revenue growth accelerate. Finally, given our strong balance sheet, prudent use of capital, and fundamental belief in the long-term value of the Seer platform, we believe there is a dislocation in our long-term value relative to our current share price. Therefore, we're putting in place an open market share repurchase program for up to $25 million. We're confident our cash balance provides us with ample runway to reach our strategic objectives of becoming the definitive tool leaders in proteomics. Now, I'd like to share some of the progress we've made across our business, starting with enhancing access to the Proteograph Product Suite. Our Strategic Instrument Placement program, or SIP, has continued to remove barriers by utilizing available operating budgets, allowing researchers to begin using the Proteograph right away. Notably, during the Q1, we saw multiple customers purchase their instruments that had been placed through the SIP, a testament to the value and quality of the data generated by the Proteograph. Additionally, we continue to serve customers through the STAC, which allows the Proteograph user to run samples in their own lab and have Seer run the mass spec, or alternatively, provide end-to-end study services from sample to answer. STAC is an important accelerator in the accessibility of unbiased proteomics data, given the elongated cell cycles due to continued funding and macro challenges. Increased accessibility will continue to catalyze the generation of third-party data and publications, further highlighting the transformative potential of the Proteograph. During the Q1, we prioritized running samples for high-value accounts with larger studies at lower price points that will serve as a key reference customers to drive continued adoption of our technology. We expect these customers will present and publish their studies in the upcoming months, further reinforcing the differentiated value proposition of our technology. While we continue to operate STAC at its capacity, the prioritization of these studies resulted in the lower STAC revenue for the quarter. Given the success we've seen with the STAC in the U.S., we're excited to expand into Europe with the launch of the STAC lab in Germany next month. This will give researchers in Europe the ability to unlock biological insight through comprehensive, deep, unbiased proteomic research. We look forward to continuing to address a major unmet need for researchers across the region. Last month, we were excited to launch our 2024 Seer Insights Grant program, aimed to support innovative and collaborative researchers who require access to comprehensive, unbiased proteomic insights to advance scientific discovery. Six awardees will receive grants to support studies ranging from 40-160 samples, leveraging our cutting-edge technology and expertise, from sample preparation to data analysis. We're looking forward to working with the scientific community to facilitate breakthroughs in oncology, cardiometabolic, and neurology fields. We see these three therapeutic areas as key areas of growth for the Proteograph Product Suite. We're accepting applications through mid-June, and the grant awards will be made in the Q3. We will complete the studies in our STAC, and grantees will have an opportunity to present their findings at a prominent scientific conference in 2025. Moving on to the validation of our technology. To date, we have seven preprints, four peer-reviewed Seer publications, and three peer-reviewed customer publications showcasing the value of the Seer technology. Since our last earnings call, we were excited to see two more manuscripts from researchers at Auburn University go through the peer review process and be published. One paper was published in FASEB and showcases the power of the Proteograph beyond plasma and biofluid samples that was exemplified in our applications lab. This paper shows how the Proteograph enables the proteomic analysis of highly complex tissues, such as skeletal muscle, and provides insight into the cellular changes that happen during cellular senescence and aging. This tissue type has a wide dynamic range of protein expression levels, with a dominance of certain key proteins similar to plasma. As such, skeletal muscle has been previously difficult to access for deep, unbiased proteomic analysis. This paper provides yet another example of the flexibility of the power of the Proteograph Product Suite to analyze novel sample types and provide differentiated insights. The second paper was published in Aging and uses skeletal muscle samples to understand molecular intricacies of aging and effects of aging and resistance training on the proteomic profiling of skeletal muscle cells. Specifically, the study found that differences in non-myofibrillar and myofibrillar proteomes were evident between the younger and middle-aged cohorts. In addition, the most differentially expressed non-myofibrillar proteins were more enriched in middle-aged participants than younger participants. In summary, they found that aging and resistance training predominantly affect non-contractile protein skeletal muscle. The novel approach of this study allowed researchers to identify exercise-related protein targets and uncover previously undetected protein isoforms. These studies further exemplify the differentiated biological insights that can be gained by investigating tissue samples using the Proteograph Product Suite to better understand aging specifically, and human health and biology more generally. In addition to these publications, we continue to see customers submitting manuscripts to preprint servers, which is commonly the first step to make a study publicly available while the manuscript is undergoing the peer review process for publication. In April, researchers from Columbia University Irving Medical Center submitted a manuscript to Research Square investigating the significance of various biofluids as important repositories of biomarkers for early detection of diseases. When comparing the Proteograph XT workflow with conventional approaches, such as neat plasma workflow, the researchers found that Proteograph XT demonstrated versatility when applied to various biofluids and outperforms other workflows in terms of plasma proteome depth, quantitative accuracy and reproducibility, while offering complete automation of sample prep. This study underscores the critical role of the Proteograph XT in advancing large studies to enable biomarker discovery, and ultimately has the potential to improve the quality of patient care. We expect to see the number of presentations and publications continue to grow throughout the year. Last month, at the American Association for Cancer Research, or AACR, annual meeting, Streck, a leader in quality controls and sample stabilization in blood, presented data from a proof-of-principle study they conducted with Seer. Their study highlighted the performance of Streck's newly developed Protein Plus BCT, a blood collection tube designed specifically for proteomic applications. The Streck data demonstrated unprecedented protein stability at room temperature across 4,000 proteins in plasma, that can be quantitatively measured with the Proteograph XT and a mass spectrometer. Seer uniquely provides the ability to look at low abundance proteins, given the sensitivity of the Proteograph assay, and the combination of the Protein Plus BCT and the Proteograph Product Suite is equally powerful for the research, translational, and clinical communities. By decreasing pre-analytical variability using a robust and standardized sample collection process, and pairing that with a robust and standardized proteomics analysis workflow, you pave the path for deep, unbiased proteomics to be as easily accessible and scalable across different labs and organizations. This is particularly important as applications for proteomics continue to expand across a growing set of end markets, exactly as genomics has done over the past 20 years. Beyond access, we've made important enhancements to our technology. Earlier this year, we made our Protein Discovery Catalog broadly available. Our customers and prospective customers can now utilize the discovery catalog to prepare their research protocols and support grant data becomes available. Feedback has been overwhelmingly positive, as scientists are able to add precision, insights, and opportunities for biomarker discovery to genomics and proteomic studies. We also continue to receive positive feedback on the power of the Proteograph XT assay. As we've said, it has been extensively demonstrated that the Proteograph XT robustly amplifies the performance of any mass spectrometer between 5 and 8-fold, in achieving depth of proteomics coverage in complex samples. Importantly, the magnitude of this amplification has been consistent, despite improvements in generation of the mass specs over the past several years. This is because the Proteograph fundamentally solves a different problem than the mass spec systems. For example, the number of proteins identified in a complex sample, such as plasma, with the leading Bruker timsTOF HT, is approximately 500-700 proteins. However, when paired with the Proteograph XT, the number of protein IDs increases to 4,000-5,000 in any given sample. Similarly, the leading Thermo Fisher Scientific Orbitrap Astral can identify 700-900 proteins in plasma. However, when paired with the Proteograph XT, the number of protein IDs in a given sample can increase to 6,000-7,000, and often 8,000 or more proteins can be identified across a given study. Importantly, the Proteograph enhances proteomics coverage using a simple and robust automated workflow. It's clear that this will be an important driver to unlock biological insights through proteomic data, and we're continuing to work to drive the inflection point of adoption of this technology. Looking ahead to the rest of 2024, we continue to execute against our core strategies of driving evidence and publications, continuing to enhance access to the Proteograph, innovate with our products, and expand our applications. With that, I will now turn the call over to David. Thanks, Omid. Total revenue for the Q1 of 2024 was $3.1 million, representing a decrease of 24% compared to $4.1 million in the Q1 of 2023. It was primarily due to a decrease in product and related party revenue. Revenue recognized primarily consisted of sales of the Proteograph SP-100 instrument, consumable kits, and service revenue, of which $1 million was attributed to related parties. Product revenue for the Q1 of 2024 was $2.5 million, including $828,000 of related party revenue, and consisted of sales of SP-100 instruments and consumable kits. This quarter, several customers purchased instruments that were placed through our SIP program, demonstrating the value these customers see in the Proteograph once it is in their hands. However, we did see continued pressure on CapEx budgets and elongated sales cycles for the outright purchase of new instrumentation. Consumable kit purchases were also lower, primarily related to lower related party consumable sales. Service revenue was $534,000 in the Q1 of 2024, including $126,000 of related party revenue, and primarily consisted of revenue related to STAC service projects. As Omid mentioned, in the Q1, we prioritized running projects for key strategic studies that will result in additional presentations and publications in the near term, but were conducted at a lower price point than our typical STAC service projects. Grant and other revenue was $36,000 for the Q1 of 2024, and consisted of leasing and shipping revenue. As we mentioned on our previous earnings call, we utilized the remaining funds available under the SBIR grant and do not anticipate booking any more revenue under this grant in 2024. Total gross profit was $1.4 million for the Q1 of 2024, representing a gross margin of 44%, compared to $2.1 million in the Q1 of 2023, representing a gross margin of 51%. Gross margins were impacted by higher installation, training, and warranty costs and lower overhead absorption due to lower overall volumes in the quarter. We continue to expect variability in our gross margin on a quarter-by-quarter basis, since the proportion of instrument, consumable, and service revenue will fluctuate for any given quarter. Total operating expenses for the Q1 of 2024 were $26.6 million, including $7.6 million of stock-based compensation, a decrease of 10% compared to $29.5 million, including $8.7 million of stock-based compensation in the Q1 of 2023. Research and development expenses for the Q1 of 2024 were $12.3 million, a decrease of 15% compared to $14.5 million in the Q1 of 2023. The decrease in R&D expenses was primarily due to a decrease in employee and stock-based compensation expenses and a decrease in laboratory expenses. Selling, general, and administrative expenses for the Q1 of 2024 were $14.3 million, a decrease of 5% compared to $15 million in the Q1 of 2023. The decrease in SG&A expenses was primarily driven by a decrease in employee and stock-based compensation expenses. Net loss for the Q1 of 2024 was $20.7 million, compared to $24 million in the Q1 of 2023. We ended the quarter with approximately $359.2 million in cash, cash equivalents, and investments. Given our strong cash position, the fundamental belief in the long-term value of our solution, and the continued dislocation in our current share price, our board of directors has authorized an open market share repurchase program of up to $25 million. This authorized share repurchase program will be effective upon the opening of our trading window, which will allow us to repurchase shares in the open market from time to time. Even with this return of capital to our shareholders, we are confident our balance sheet provides us with ample cash runway to reach our strategic objectives over the long term. Turning to our outlook for the year, we now expect revenue to be in the range of $16 million-$18 million for 2024, which is in line with our revenue from 2023. We continue to expect revenue to be more weighted to the H2 of the year. We are committed to maintaining a strong financial position and are taking a very disciplined approach with our spend. Given that our revenue ramp continues to develop more slowly than anticipated, we feel it is necessary to reduce our operating expenses in order to align our cash burn with our revised revenue expectations. As Omid shared, we have implemented a reduction in force of approximately 10% of our workforce. This action represents a strategic alignment of our resources towards our commercial efforts. We are also taking measures to reduce our non-personnel operating expenses for 2024. While it is always difficult to make these changes, we feel this is a necessary step for us to position the organization for success over the long term. Free cash flow loss was approximately $11.2 million for the Q1 of 2024, and as previously stated, we estimate that our 2024 free cash flow loss will be less than our free cash flow loss in 2023. At this point, I would like to turn the call back to Omid for closing comments. Thank you, David. We remain committed to reducing barriers to the commercial adoption of our technology. The journey to commercialize innovative technology is never linear. I continue to be grateful to our team for their hard work and dedication they are putting in every day. I'm confident in our technology and believe that as our publication base expands, we will see increased adoption of our technology. I look forward to keeping you updated on our progress. With that, we will now open it up to questions. Operator? Thank you. At this time, we will conduct the question-and-answer session. As a reminder, to ask a question, you will need to press star one one on your telephone and wait for your name to be announced. To withdraw your question, please press star one one again. Please stand by while we compile the Q&A roster. Our first question comes from the line of Yuko Oku of Morgan Stanley. Your line is now open. Hello, thank you for taking my question. With respect to lowering the barrier for access to mass spec via STAC for genomics customers, could you talk to the proportion of STAC customers coming from genomics researchers versus traditional mass spec researchers? Yuko, this is Omid. Thanks, thanks for the question. I think the customer base is actually relatively similar, meaning there are customers of STAC who actually have in-house mass spec and just because of capacity constraints they send their mass spec to us. Now, we don't do any mass spec services for any non-Seer customer, meaning the customers who send their mass spec to us, these are Proteograph owners who are running the Proteograph in-house, have access to a mass spec in-house, but choose, because of ease and capacity reasons, to leverage our mass spec. We have some customers like that on the STAC that serve those customers. But the lion's share of the customer base is actually customers who don't have access to a Proteograph or a mass spec in-house, and they end up with end-to-end services at our STAC. Got it. Thank you for that. And then with green shoots and biotech funding being called out by many of your peers, while it may be too early for environment to be improving, do you feel that sentiment is turning? Yeah, Yuko, this is David. Thanks for the question. What we certainly saw in the Q1 is some budget impact from biopharma for sure. Certainly the large biopharmas. We had, you know, a couple deals, actually, that we were expecting that got pushed for budgetary reasons, so we're still seeing an impact. That said, you know, the use of STAC by some of our smaller biotech firms has been good. So to your point around green shoots, I do think it kind of depends. I think in the case of large biopharma, the adoption of new technologies, especially where it requires CapEx, can still be challenging. Where it's a service model, STAC model, I think we're seeing good reception there. And so again, I think it depends obviously on the company and the situation, but again, we are still seeing some headwinds. Of Rachel Vatnsdal of JP Morgan. Your line is now open. Hi, thank you for taking the questions. This is Marta Zaremba, that's on for Rachel Vatnsdal from JP Morgan. So I wanted to touch a little bit on your updated guidance. Can you perhaps discuss the two key top-line expectations, and then touch a little bit more on seasonality? First part of your question, you wanted the two key. I missed what you asked. Just like, Q2 top-line expectations. Got it. Q2 top line. Got it. Okay. So in terms of, you know, Q2, we don't give quarterly guidance. I think what we're seeing is we're continuing to see, you know, lots of opportunities in the pipeline. It's just a question of, you know, the elongated sales cycle through that pipeline in terms of how quickly we can move those through. So I'd say Q2, we're gonna continue to be conservative in our outlook, just given what we see and some of the headwinds we've been facing. In terms of the, you know, seasonality, I do think we'll continue to see the seasonality we've seen in years past. I think certainly the revenue will be more H2 weighted, in terms of what we see. We certainly have some interesting publications coming out. We expect in the late second, early Q3, which we think was gonna help drive continued interest in the platform. And so we do, you know, experience the same seasonality that the industry generally sees, which is, you know, a very strong kind of Q4 is the strongest quarter of the year, given where people are in their cycles and things. So we would expect the same here, and certainly with our year being back-end weighted. Thank you. That's helpful. And then can you talk about STAC traction a bit more? You touched on it on the call a little bit, but I remember last quarter, you talked that you have 48 organizations that are using STAC. How many do you have as of now? And then, do you still have a backlog of projects? And then lastly, on STAC, can you talk about your visibility on the revenue layer, especially now that you're opening a new center in Europe? Thanks. Yeah, thanks so much. I don't have an update in terms of the updated total customer number beyond what I mentioned last time. The STAC continues to run at capacity, and we expect that to be the case through Q2 and also into Q3. And my visibility for it is that the STAC was exactly what the market needed, meaning the purpose of establishing it in US was to lower the barrier for a potential customer to access the Proteograph data. It was also meant to lower the barrier for a potential customer to bring in a Proteograph when they're relatively unfamiliar with the mass spec, and so we didn't want that lack of familiarity with the mass spec to be a hindrance to taking a Proteograph in-house. In that context, the STAC has done exactly what we had hoped. By the way, so has the SIP program in terms of lowering barrier. And the challenge for us was that we were serving US customers, but not European customers, given the GDPR rules with data, et cetera, going across the ocean. And now we're opening the European STAC will be able to provide similar types of services to our European customers. And as I mentioned earlier to Yuko, the customer base really is diverse. It's both customers that have a Proteograph in-house that may or may not have a mass spec in-house, but it's also genomic customers, some of them folks that want to do large scale studies that get access to the STAC for end-to-end services. So my expectation is that STAC will continue to be an important source of product adoption for us. But it really is not meant for us to pivot into a service business. And I mentioned that the very, very first time that we announced this STAC, it's really meant to facilitate adoption of our platform. Great, thank you. All right. Thank you. I am showing no further questions at this time. This does conclude the question and answer session and the program. Thank you for your participation in today's conference. You may now disconnect.
