Thank you and good afternoon, everyone. Today, I'll share our first quarter 2025 results, highlight recent commercial and strategic progress and outline our expectations for the remainder of the year. Following my remarks, Jim Gibson, our new Chief Financial Officer, will discuss our financial results and guidance in much more detail. We reported first quarter 2025 revenue of $37.2 million, which is slightly above our preliminary estimate shared on April 9 and consistent with our internal expectations. Instrument revenue for the quarter was $11 million compared -- lower than compared to the prior year, largely reflecting increased uncertainty in academic funding, particularly in the United States. In total, we shipped 12 Revio systems and 28 Vega systems, bringing cumulative shipments of to 282 Revio systems and 35 Vegas systems. To provide more transparency into our customer dynamics, we've introduced new metrics on Slides 4 and 5 of our investor presentation, which break out shipment dollars by customer type. While we don't expect to share this segmentation every quarter, we believe it offers helpful context, particularly in light of the current market conditions. As shown on Slide 4 in our Q1, the Academic and Research Institute segment represented the lowest percentage of instrument shipments since the Revio launch. We believe that this is the direct result of increased funding pressures our customers are seeing with respect to capital equipment purchases. By contrast, instrument shipments to our other customer segments have remained largely stable over the past several quarters. Notably, we saw growth among our hospital and clinic customers, reflecting continued momentum for HiFi sequencing in clinical and translational research settings. And despite broader funding headwinds, we continue to attract new customers to PacBio. Roughly half of all Vega and Revio systems shipped in Q1, went to new instrument customers, further showing the expanding market appeal of our HiFi technology. While macroeconomic pressures weighed on system placements, consumables showed strong growth in the quarter. In the first quarter of 2025, consumable revenue reached a record $20.1 million, reflecting 26% year-over-year growth and steady utilization across our growing base of Revio systems. Typical fiscal year-end purchasing in Japan also contributed to the strong performance. Notably, unlike instrument shipments, consumable demand from our Academic and Research Institution customers remained stable compared to prior quarters, indicating more resilience in usage-driven spend versus capital purchases. Further underscoring HiFi adoption, total petabase output from PacBio long-read sequencers increased 37% year-over-year, highlighting continued scaling across our installed base. Turning to our full-year outlook; the macroeconomic environment remains exceptionally challenging. Since our April press release, the impact of newly implemented tariffs between the U.S. and China, combined with additional pressure from proposed NIH budget reductions for fiscal year 2026, have introduced incremental risks that could have an impact on revenue in 2025. In light of these developments, we are adjusting the lower end of our previously guided revenue range by $5 million. We now expect full-year 2025 revenue to be between $150 million and $170 million. The environment remains dynamic, and should tariff conditions or academic funding further deteriorate, we may face additional headwinds. That said, we are confident in our strategic direction, anchored by strong customer interest in long-read sequencing, continued momentum in the adoption of HiFi, and a robust innovation map. We are also committed to our plan of turning cash flow positive as we exit 2027 and remain focused on disciplined cost management to reduce our cash burn. In response to ongoing market uncertainty and headwinds in the industry, we announced and executed on a restructuring plan in April, designed to narrow our strategic focus and reduce our operating costs. Through reductions in headcount and non-headcount-related expenses across all functions in our organization, we expect to lower our annualized non-GAAP operating expense run rate by approximately $45 million to $50 million by year-end. Following these cost reduction measures, we are concentrating our efforts on our highest impact long-read platform initiatives. We continue to advance development programs aimed at enhancing our existing platforms such as Revio and Vega, including the future launch of multi-use SMRT Cells. This innovation is designed to further reduce sequencing costs for our customers to unlock higher sequencing volume while simultaneously improving our consumable gross margins. The development program is progressing quickly, and we've demonstrated high-quality, repeatable reuse results internally. Additionally, we are accelerating development efforts for our ultra-high throughput long-read sequencing system. This next-generation platform is expected to significantly increase throughput, enabling human whole human genome sequencing costs at or near price parity with short-read technology. I'd also like to provide a brief update on how our restructuring initiative has impacted our short-read sequencing strategy. While we continue to see strategic value in providing both long-read and short-read sequencing technologies to the market, the current macroeconomic conditions necessitate focusing our resources and investments on areas where we believe we can achieve the greatest market share gains and hold the strongest competitive differentiation. Based on these criteria, we are prioritizing our HiFi technology and the long-read sequencing market and have made the decision to pause development of our high-throughput short-read sequencing platform. Although, we have paused our development of the high-throughput short-read platform, we remain fully committed to selling the Onso platform and supporting our current Onso customers through ongoing commercial support and consumable supply. Moving on to product updates. In the first quarter, we continued to roll out our new Spark chemistry, which significantly enhances Revio's data output and performance while reducing the amount of DNA input required. Customer uptake has exceeded expectations with nearly 90% of our Revio reagent kit shipments in the first quarter being Spark chemistry. And we're certainly pleased with our customers' response. Early adopters like Syneos Biosciences, a global leader in genetic testing services, reported yield increases of 46% relative to their experience with the version one chemistry and emphasized how Spark's lower sample input requirements has unlocked the ability to sequence previously inaccessible samples. Similarly, the University of Burn highlighted substantial productivity and cost efficiency improvements across various genomic research applications. Turning to Vega. Early customer response has been very encouraging. Users are achieving strong yields, consistently exceeding our specification of 60 gigabases of HiFi data per SMRT Cell and deploying the platform across a wide range of applications. For example, the integrated microbiome resource at Dalus University is using Vega for microbial genomics and eDNA amplicon sequencing for worldwide client samples, while Eligen is applying to Amplicon sequencing in support of DNA synthesis workflows. We're also seeing the adoption in labs for gene editing research and targeted sequencing applications. These early use cases reflect Vega's accessibility, ease of use and versatility, enabling us to broaden our customer base, expand into new markets and bring HiFi sequencing into new labs beyond the traditional large-scale whole genome applications. Notably, approximately 50% of Vega shipments through Q1 were to new to PacBio instrument customers. Looking ahead, we expect to continue ramping Vega manufacturing through the second quarter and reach a run rate production in the second half of 2025. On the informatics front, we recently announced a licensing agreement with the Chinese University of Hong Kong and the Center for Novistics to integrate advanced deep learning models into our sequencing workflows, significantly enhancing methylation detection accuracy and enabling comprehensive analysis of critical epigenetic markers such as 5MC, 6MA and native 5-HMC. The ability to profile 5-HMC, a dynamic tissue-specific marker implemented in brain development, cancer and neurodegenerative diseases opens new opportunities in liquid biopsy, cancer detection and cell-free DNA analysis. Several customers, including clinical customers like GeneDx and Children's Mercy, Kansas City Hospital have recently implemented methylation analysis into their test, and we believe that the addition of these new models will further strengthen our platform's leadership in epigenetic sequencing and help enable clinical researchers to find greater insights from HiFi genomes. Moving on to other recent highlights. We are proud to have been selected as the technology partner for the Davos Alzheimer's Collaboratives North American Dementia Registry project. This initiative aims to build a comprehensive multiomics data set, advancing global understanding of Alzheimer's genetics, especially within diverse and underrepresented populations. We also continue to gain momentum with our new and existing clinically focused customers in the first quarter, especially with the hospital and clinic customer base. Revio placements in the quarter included leading institutions such as the Lilly Children's Hospital in Chicago, Imagine Institute in France and the Institute of Medical Genetics at the University of
