Thanks, Karina. Good afternoon, and thank you for joining us on our fourth quarter and full year earnings call. 2025 was a remarkable year for Adaptive, marked by strong execution and meaningful progress across the business. As shown on Slide 3, in the MRD business, full year revenue grew 46% year-over-year, and we achieved profitability ahead of expectations. We also delivered several key catalysts in the year that position the business for sustained growth and continued margin expansion. These include accelerated EMR integrations, including the integration of clonoSEQ into Flatiron's Onco EMR, expanding access across the community setting. The launch of NovaSeq X+ to help scale operations and improve margins. Our first Medicare coverage for recurrence monitoring in MCL, expanding the lifetime value of each MCL Medicare patient, updates in NCCN guidelines across all reimbursed indications, which continues to deepen clinical validation and strong data generation, which was marked by an all-time high with over 90 abstracts presented at ASH, reinforcing MRD's growing role as an interventional tool in patient care. In the Immune Medicine business, we scaled our TCR antigen data and modeling capabilities, leading to our first 2 data partnerships, and we completed a preclinical data package for our lead TCR depleting antibody program in ankylosing spondylitis. Taken together, the strong MRD execution, the continued progress in Immune Medicine and the disciplined spending across the organization drove 55% total company revenue growth and a 68% reduction in cash burn, leading to a strong cash balance of $227 million at year-end. Let's turn to Slide 5 for a closer look at the MRD performance and future expectations, starting with clinical testing. ClonoSEQ clinical testing revenue grew 64% for full year 2025 and 59% in the fourth quarter compared to the prior year. As shown in the chart, volumes increased sequentially throughout the year, reaching a new record of 30,038 tests in the fourth quarter, up 43% year-over-year and 11% sequentially. Growth was broad-based across all reimbursed indications with DLBCL, MCL and multi myeloma driving the majority of year-over-year growth. Multiple myloma represented 44% of U.S. clonoSEQ volume followed by ALL at 30%, CLL and DLBCL, both at 9% and MCL at 5%. Volume growth throughout the year was driven by a combination of interrelated factors, including blood-based testing, community presence, EMR integrations, clinical guideline inclusion and ongoing data generation. In the fourth quarter, blood-based testing accounted for 47% of clonoSEQ tests, up from 41% a year ago. In multi myeloma, blood-based testing reached 27%, which is a 6% -- 6-point increase year-over-year, which is particularly meaningful given the bone marrow-based nature of the disease. Community testing also continued to expand with volumes up 18% sequentially and representing approximately 33% of total tests in the quarter. We further scaled our digital footprint, completing Epic integrations in 8 accounts during the quarter, bringing the total to 173 integrated accounts, which now drive approximately 40% of ordering volume. Finally, NCCN guideline updates and continued data readouts across marketed indications supported our commercial execution. Ordering HCPs increased 9% sequentially and 45% year-over-year in Q4, with particularly strong adoption in the community setting. Taken together, these drivers continue to increase both physician adoption and testing frequency per patient across indications. Turning to Slide 6. In addition to volume, clinical revenue growth was also driven by continued ASP expansion. We ended the year with an average ASP in the U.S. of $1,307 per test, up 17% year-over-year, and we exited the fourth quarter at about $1,350 per test. ASP growth during the year was driven by strong execution from our reimbursement team across several initiatives. These include the successful renegotiation of 8 major payer contracts with national and regional payers, including Humana, Aetna, Horizon and multiple Blue Cross plans as well as the signing of new agreements with Anthem, Centene, Florida and LA Care. We also expanded commercial coverage policies with new coverage wins in DLBCL and in CLL. In parallel, we delivered meaningful revenue cycle management improvements, including Medicaid collections, appeals, prior authorization processes and time to cash. These operational enhancements supported by AI-enabled workflows are driving higher paid claim rates more consistent realization and improved commercial payer cash collections year-over-year by 74%. Looking ahead, we expect these initiatives, together with 2 additional large national payer contracts, we anticipate closing this year to support our targeted average ASP of approximately $1,400 per test in 2026. Turning to Slide 7. Our MRD pharma business had a strong year with revenue growth of 20% year-over-year, including $19.5 million in regulatory milestone revenue. Excluding milestones, pharma grew 11%, and we ended the year with approximately $210 million in backlog. Several important shifts in our pharma portfolio are worth highlighting: First, multi myeloma remains the largest driver, accounting for roughly 70% of sequencing revenue and approximately 60% of backlog; second, CLL and ALL bookings more than tripled in 2025 supported by emerging data underscoring the need for higher sensitivity MRD to differentiate therapies in both disease states as well as updated NCCN guidelines for fixed duration regimens in CLL. Third, MRD is increasingly embedded directly into regulated interventional trials with approximately 60% of our portfolio, including MRD as an endpoint, up from about 40% in 2024. This shift has been driven by regulatory momentum including the ODAC recommendation and most recently, the subsequent FDA draft guidance supporting MRD as a primary endpoint in multi myeloma accelerated approvals. Of note, registrational trials that incorporate MRD carry higher economic value and have a halo effect in the clinical business. Overall, we're encouraged by the expanding role of MRD across hematologic oncology trials, and we believe broader endpoint adoption, increased testing time points and the need for greater sensitivity will continue to drive MRD pharma revenue growth. Turning to Slide 8. Our focus this year is clear: continuing driving top line growth while expanding margins building on the same durable growth drivers that powered performance in 2025. In 2026, we expect clonoSEQ test volumes to grow by more than 30% year-over-year, supported by a continued mix shift towards blood-based testing, which we expect to exceed 50% of total MRD volume, deeper penetration in the community setting, where we expect more than 35% of testing to originate, further scaling of our EMR integration effort adding approximately 40 with a focus on high to mid-volume accounts, and continued generation of clinically meaningful data across multiple indications to further expand interventional use and support the guideline evolution. From a pricing standpoint, we expect to increase ASP to an average of about $1,400 per test based on the initiatives described earlier. In pharma, we plan to increase the number of registrational and primary endpoint studies across multi myeloma, CLL and DLBCL, leveraging growing regulatory and clinical endorsement of MRD. We also expect continued margin expansion driven by higher volumes throwing through the NovaSeq X+ and operating leverage across our production and our commercial infrastructure. We believe these priorities position MRD as a scalable, durable and increasingly profitable growth engine for Adaptive in 2026 and beyond. Now let's turn to Slide 10 to discuss Immune Medicine. The premise of our Immune Medicine business is to generate large-scale, proprietary immune receptor data that allows us to understand how T cell receptors bind to antigens and how those interactions drive immune responses across cancer, autoimmunity and infectious diseases. Over the past year, we have continued to scale this data we now have more than 5 million paired TCRs spanning over 20,000 antigens and nearly 50 HLA types, a data set that is orders of magnitude larger than is one is publicly available. We believe this scale is sufficient to train predictive models of the adaptive immune response across diseases. In parallel, we are applying our platform to identify what we believe are likely disease-causing T cell receptors and their antigens in certain autoimmune conditions, including type 1 diabetes, celiac disease and multiple sclerosis. These insights have the potential for TCR-based target discovery to enable existing and future partners develop -- to develop immune-based therapeutics. Turning to Slide 11, I'll briefly review our 2025 achievements and how they set us up for our 2026 strategy. First, we began to monetize our data with 2 distinct licensing deals with Pfizer. One is a data licensing agreement in which Pfizer has access to a subset of our TCR antigen training data. Pfizer will use this data to develop and train its AI and machine learning models to accelerate research and drug discovery in multiple disease area. The second licensing deal focuses on target discovery and rheumatoid arthritis or RA. Here, we are applying our IM platform and capabilities to identify the specific autoreactive T cell receptors that are highly enriched only in RA patients. Pfizer will then use these data to accelerate its research and development of potential RA therapeutic candidates. Together, these partnerships continue to validate the strength of our differentiated platform and the value of our large-scale proprietary data. In addition, we completed a preclinical data package for our lead antibody program in ankylosing spondylitis. While potential next steps include initiating IND-enabling studies, we made the strategic decision to stop further investment in this program and instead prioritize capital toward data generation and AI modeling. These are key areas we believe leverage our core differentiation and represent the highest return on investment for Immune Medicine. Along with these key achievements, we also maintained a disciplined capital allocation, executing against our objectives while keeping annual Immune Medicine cash burn to around $30 million, as promised. Looking ahead to 2026, we plan to continue advancing on our TCR antigen data sets and our AI/ML modeling work with a lower target net cash burn of $15 million to $20 million. We continue to focus on securing additional data partnerships, which we believe have the potential to drive meaningful long-term upside for Adaptive. Now I'm going to pass it over to Kyle, who's going to walk through the financial results and our 2026 full year guidance. Kyle?
