Good afternoon, and thank you for joining our third quarter 2025 earnings call. Starting on slide three, Q3 was an exceptional quarter for Guardant Health, with broad-based growth across our business. Technology volumes grew 40% as year-over-year volume growth continued to accelerate, driven by Guardant360 Liquid, Guardant360 Tissue, and Reveal. Our biopharma business grew nicely year over year with positive CDx momentum, and screening volume accelerated with a sequential increase of 8,000 Shield tests. Importantly, screening has started to generate meaningful revenue, tracking at an annual run rate of approximately $100 million, roughly one year into the commercial launch of the FDA-approved product. Overall, we are very pleased with our performance this quarter, delivering 39% year-over-year revenue growth and crossing over $1 billion in annualized revenue for the first time. Excluding screening, we reached a major milestone, with the rest of the business becoming cash flow positive one quarter earlier than expected. Indeed, this quarter sets us up very well to deliver on the long-term plan that we laid out at our investor day last month. Lastly, we recently surpassed 1 million cumulative clinical patients tested by Guardant Health, and as such, we want to highlight one of these patients with a story that captures the profound impact our tests are having in everyday clinical practice. A 67-year-old man had gone unscreened for colorectal cancer for several years, despite his physician offering colonoscopy or stool-based tests annually beginning in 2021. Each time, the patient declined to be screened. In December 2024, the physician ordered a Shield blood test, and the patient agreed to complete the blood draw during the same visit. The result came back positive. When his physician explained that a positive Shield result required a follow-up colonoscopy, the patient agreed to have the procedure despite previously resisting. The colonoscopy was performed in January of 2025, revealing colorectal cancer. The patient quickly began treatment, and at his most recent follow-up, he had successfully completed therapy and was doing well. This is a powerful example of how the Shield blood test can remove barriers to screening, provide a more pleasant and convenient option for patients, and ultimately improve outcomes. Now turning to top-line performance in slide four, Q3 revenue grew 39% year over year to $265 million, with strong performance again across our oncology, screening, and biopharma and data businesses. Taking a closer look at our oncology business on slide five, oncology revenue increased 31% to $184 million, and oncology volumes increased 40% year over year to approximately 74,000 tests in the third quarter. Turning to slide six, we have seen a clear acceleration in volume since July of last year, following the introduction of Guardant360 Liquid on our smart platform. Since then, we have launched two additional waves of applications, driving five consecutive quarters of accelerating volume growth, and we look forward to future waves of smart app introductions developed through the power of Infinity AI to help fuel future growth. In addition to Guardant360 Liquid, Guardant360 Tissue and Reveal volumes also experience strong year-over-year growth. Moving on to slide seven. As a reminder, our Infinity AI learning engine applies AI across our data treasury of over 1 million patient samples, including more than 350,000 epigenetic profiles across more than 100 tumor types, to bring powerful insights and new products to market faster than ever. Infinity AI enables higher resolution mapping of tumor biology, giving rise to not only entirely new products in the clinical business, but novel signatures for faster drug discovery relevant to our biopharma business and new commercial insights and decision support tools. Turning to slide eight. To date, we've launched 15 groundbreaking smart apps on Guardant360 Liquid, with dozens more in development that will roll out across Guardant360 Liquid, Tissue, and Reveal. Each new application builds towards what we see as a GPS for cancer care, guiding physicians with the right insights at every step of the patient journey. We believe these applications not only significantly expand the clinical utility of Guardant360 Liquid, but further extend our technical leadership in the liquid CGP market. Looking more closely at some of the recent highlights within our oncology business on slide nine, Guardant360 volume grew exceptionally, with more than 30% year-over-year growth. Guardant360 Tissue also had a great quarter, showing strong year-over-year acceleration following the major product upgrade released in the second quarter. Once again, Reveal contributed very nicely and continues to be our fastest growing oncology product. In addition to the strong performance, we recently reached a major milestone with the submission of our PMA application to the FDA for Guardant360 Liquid. This submission has the potential to streamline Guardant360 Liquid with a single flagship FDA-approved liquid biopsy for therapy selection, simplifying our portfolio, accelerating adoption, and further strengthening our leadership in this space. In addition, FDA approval would lay the foundation for ADLT designation, which is an important mechanism for capturing the appropriate value for our expanded test offering in the future. We had a strong presence at ESMO 2025, with 15 abstracts spanning the cancer care continuum from MRD detection and recurrence monitoring with studies such as Pegasus to advanced stage tumor profiling and therapy response assessment. For Reveal, we're making great progress with data generation and publications. We recently submitted our immuno-oncology therapy monitoring data package to MolDX to support Medicare reimbursement and submitted data from our chemotherapy monitoring study for publication. Turning to slide 10 to take a closer look at our Reveal data pipeline. Over the last few months, we've made significant progress in MRD, generating and publishing compelling data across multiple cancer types. Earlier this year, we achieved Medicare coverage for CRC surveillance and have since submitted dossiers for breast surveillance and, as I just mentioned, for immuno-oncology therapy monitoring. We plan to submit packages for chemotherapy and CDK4/6 inhibitor monitoring following those publications. Looking ahead, we have ongoing studies across more than five additional tumor types in both the adjuvant and surveillance settings. Together, this growing body of evidence will continue to strengthen the clinical utility and analytical validity of Reveal, supporting broader adoption in MRD. Turning now to slide 11, I'm proud of the progress we have made over the last few years in both driving demand and revenue growth across our portfolio. Looking ahead, we see multiple drivers across our oncology business that position us well for durable long-term growth. We will continue investing in commercial initiatives that make it easier for physicians to access our tests through portal enhancements, EMR integrations, and enhanced workflows. In our therapy selection business, transitioning to the smart platform unlocks wave after wave of novel applications, many unique to Guardant, that will help us differentiate and continue gaining market share. In MRD, a redoubled commercial focus on Reveal, supported by significantly lower COGS and Medicare coverage for CRC surveillance, positions us for strong growth ahead. We're also excited to introduce an ultra-sensitive tissue-informed MRD assay that will complement our best-in-class tissue-free Reveal test. Looking more closely at some of the recent highlights within our biopharma and data business on slide 12, we delivered another strong quarter with third-quarter revenue growing 18% year over year. We continue to deepen our relationships with large pharma and had two additional companion diagnostic approvals in Q3. In late September, Guardant360 CDx received FDA approval as a companion diagnostic to Enluro for the treatment of ESR1 mutated advanced breast cancer. This marks the second FDA-approved indication in breast cancer and the sixth overall CDx claim approved by the FDA for Guardant360 CDx. We also received regulatory approval in Japan for Guardant360 CDx as a companion diagnostic to Enhertu for non-small cell lung cancer patients with HER2 mutations. We now have 23 total CDx approvals across biomarker and tumor types. Our robust and growing pipeline of partnerships ensures that near-term revenue visibility remains high. With that, I will now turn the call over to AmirAli for an update on screening. Thanks, Helmy. Moving on to slide 13, we delivered $24 million of Shield testing revenue in Q3, driven by approximately 24,000 tests. It's been incredibly rewarding to see Shield volume take off and hear story after story of patients positively impacted by this pioneering test, such as the story Helmy highlighted at the beginning of our call. Now, turning to slide 14 to take a closer look at screening highlights for the third quarter of 2025. Starting with CRC screening, given the strong performance and growing demand, we have accelerated the building out of our commercial infrastructure beyond our original plan. In addition, the breakthrough nature of the Shield brand has provided us with strategic partnership opportunities, including our recently announced collaborations with Quest Diagnostics and Path Group. Shield continues to generate strong demand from both patients and physicians with high adherence rates. As exemplified by the patient's story we shared earlier, we are seeing Shield tests get completed with blood samples received for more than 90% of ordered cases. This demonstrates the simplicity of Shield as a routine blood test for CRC screening that can be implemented into routine PCP practice. We are encouraged by the performance of our Shield CRC V2, which demonstrated solid clinical performance with improved sensitivity for stage I colorectal cancer. Turning to our multicancer initiatives, we are very excited to announce that Shield Multicancer is now available nationwide through our clinical data collection initiative. At our investor day last month, we shared strong real-world performance data for Shield MCD from a study of 9,251 individuals. Specificity was 99%, consistent with earlier NCI findings, and positive predictive value was 41%, meaning that when Shield MCD is positive, there was a 41% likelihood of cancer being present. Lastly, we are proud to partner with the American Cancer Society and look forward to ensuring that everyone has access to convenient and timely cancer screening so we can detect cancer earlier and provide opportunities for better outcomes. Taking a closer look at our recent strategic partnerships to scale our commercial infrastructure on slide 15. First, we were very excited to announce a strategic collaboration with Quest to expand and accelerate Shield access more broadly in the U.S. Quest's provider clients will be able to order Shield tests and receive results directly through the Quest connectivity system. We believe this strategic collaboration is valuable in two ways. First, it enables a better ordering experience and brings forward our nationwide EMR strategy by several years. This will give us immediate connectivity to 650,000 clinician and hospital accounts in the Quest system. We believe this accelerated connectivity will drive our scale. We will also have access to deep logistical infrastructure, including 2,000 patient service centers and 6,000 in-office phlebotomists in the United States. Second, Quest's promotional activities using their nationwide field force, in combination with our own multi-hundred-person sales force, will further strengthen our competitive position in the primary care market. Quest's national commercial sales team will proactively educate primary care physicians and OBGYNs about the Shield test, accelerating awareness and adoption among their ordering providers. We expect Shield to be available for physician order through Quest in the first quarter of 2026. We will continue to process all Shield tests and control client services and billing and reimbursement operations. In addition, we recently announced our partnership with Path Group, which expands Shield's reach to more than 250 health systems across 25 states, representing another exciting accelerator for physician and patient access. We are looking forward to seeing the positive impact of our growing commercial infrastructure in 2026 and years to come. We also remain confident in the potential inclusion of Shield in the American Cancer Society guidelines in the near future, which should be a catalyst for broader patient access. Moving on to slide 16, our goal has always been to detect many cancer types early when they are most treatable. With that in mind, we developed Shield as a multicancer detection platform. Turning to slide 17, and as I mentioned earlier, we have now broadened access to Shield multicancer detection. In order for a patient to access this result report, their physician will need to opt in to receive the multicancer report, and the patient will need to authorize the release of medical records to Guardant Health. We successfully piloted this workflow in several accounts, and following overwhelming positive feedback from physicians and strong participation by patients, we expanded this offering nationwide. Moving on to slide 18, the launch of this initiative establishes a scalable platform for clinical data generation, enables assessment of the utilization of MCD results in patient care, and provides a new avenue to expand patient access to multicancer detection, bringing this important innovation to a broader population. This nationwide initiative is expected to reach hundreds of thousands of participants, making it one of the largest prospective evidence generation initiatives for early cancer detection. Turning now to slide 19, with the expansion of Shield to include MCD results together with patient authorization to release medical data, we are now well positioned to further strengthen our data modes. This high-quality data serves as a regulatory-grade source of truth, providing details on each patient's cancer journey that were previously not accessible. We will generate large-scale prospective evidence about the performance, clinical value, and safety profile. We believe this high-resolution data will power continuous improvement of Shield MCD and also lay the foundation to potentially expand into multi-disease detection. With that, I will now turn the call over to Mike for more detail on our financials. Thanks, AmirAli. Turning to slide 20, I'll now review select financial highlights for the quarter ended September 30, 2025. Unless otherwise noted, all growth rates are year over year. Total revenue for the third quarter grew 39% to $265.2 million, driven by strong performance across all three major revenue lines: oncology, biopharma and data, and screening. Oncology revenue increased 31% to $184.4 million, primarily driven by another quarter of accelerated test volume growth. We reported approximately 74,000 oncology tests in the third quarter, representing 40% growth, reflecting continued positive momentum across the portfolio. Guardant360 Liquid delivered its fifth consecutive quarter of accelerating growth, with volumes up more than 30%, supported by the expanding clinical utility enabled by smart apps launched over the past year. Guardant360 Tissue also had an exceptional quarter, showing strong year-over-year acceleration following the major product upgrade released in the second quarter. Reveal remains our fastest growing oncology product, benefiting from CRC surveillance reimbursement achieved early this year and continued strength across both breast and lung cancer indications. As a reminder, we do not include Guardant hereditary cancer testing or IHC volumes in our reported totals. We continue to expect minimal revenue contribution from these new offerings through 2025. Average selling prices remain stable compared to the prior quarter. Guardant360 Liquid was in the range of $3,000- $3,100. Guardant360 Tissue was approximately $2,000, and Reveal was in the range of $600 to $700. We also recognized approximately $5 million of out-of-period oncology revenue in the third quarter, compared to $12 million in the prior year period. Our biopharma and data business continued to perform well, with revenue increasing 18% to $54.7 million, which includes milestone revenue from two companion diagnostic approvals achieved during the quarter. The biopharma pipeline remains solid, providing confidence in both the near-term and long-term growth prospects. Screening revenue from Shield totaled $24.1 million, generated from 24,000 tests reported during the quarter. Shield ASP was approximately $880 above expectations, reflecting our continued focus on Medicare-covered patients. We also recognized approximately $3 million of out-of-period screening revenue, driven by better-than-expected reimbursement from Medicare Advantage payers for tests performed in the first half of 2025. This positive trend reinforces our confidence in both near-term and long-term expectations for Medicare Advantage reimbursement rates and overall Shield ASP targets. Turning to slide 21, we're very pleased with the year-over-year improvement in non-GAAP gross margin, which increased to 66% in Q3 2025, compared to 63% in the prior year period. This improvement was primarily driven by a significant reduction in Reveal COGS, which have declined from over $1,000 per test in Q3 2024 to less than $500 per test, as well as strong progress in Shield gross margin. Shield's non-GAAP gross margin improved from negative levels at the launch just over a year ago to 55% in the third quarter of 2025. This improvement reflects strong ASPs under the Medicare ADLT rate of $1,495, disciplined focus on reimbursable tests, and continued COGS reduction. Shield's non-GAAP cost per test again trended lower sequentially and continues to be below $500 per test, consistent with our operational plan. These gains reflect the ongoing benefits of increased Shield volume and disciplined cost management. Turning to slide 22, non-GAAP operating expenses were $228.8 million in the third quarter, an increase of 22% in line with expectations. The increase was primarily driven by continued investments to expand our screening commercial infrastructure and scale sales and marketing for Shield. As we conclude 2025 and enter 2026, we'll maintain focus on these investments to maximize our first mover advantage in blood-based colorectal cancer screening. Adjusted EBITDA loss was $45.5 million, an improvement of $10.7 million compared to a loss of $56.2 million in the third quarter of 2024. We remain disciplined in our approach to cash management. Free cash flow burn was $45.8 million, improving by $9.5 million compared to the prior year period. Importantly, excluding the screening business, Guardant Health generated positive free cash flow during the quarter, a significant milestone achieved one quarter ahead of our stated target. We expect the core business to remain free cash flow positive in the fourth quarter, as well as for the full year 2026 and beyond. We ended the quarter with approximately $690 million in cash, cash equivalents, and restricted cash. Turning to the full year 2025 outlook on slide 23. Based on our strong year-to-date performance, we are raising full year 2025 revenue guidance for the third time this year to a range of $965- $970 million, representing approximately a 31% growth compared to 2024. At the midpoint, this represents an increase of $47.5 million versus our prior range. We now expect oncology revenue to grow approximately 25% year over year, up from prior guidance of 20%, driven by stronger than expected oncology volumes in the third quarter and higher expected volumes for the remainder of the year. We now forecast total oncology test volume to grow more than 30% compared to our previous expectation of greater than 27%. Our biopharma and data business remains on track to deliver mid-teens growth for the full year. We're also increasing our Shield revenue guidance to $71 million- $73 million, up from $55 million- $60 million, reflecting higher expected volume of 80,000 tests- 82,000 tests compared to prior guidance of 68,000 tests- 73,000 tests. With continued improvement in gross margins, we're raising our full year non-GAAP gross margin guidance to 64%- 65%, up from 63%- 64%. As previously outlined, we plan to reinvest incremental screening gross profit to accelerate commercial expansion. Accordingly, we now expect 2025 non-GAAP operating expenses to be in the range of $865 million- $875 million, representing a 14%- 16% increase compared to 2024. Finally, consistent with our long-term financial roadmap, we remain committed to reducing cash burn each year and achieving company-wide cash flow breakeven by the end of 2027. For full year 2025, we continue to expect free cash flow burn of $225 million- $235 million and improvement from $275 million in 2024. Turning to slide 24, we began 2025 with an ambitious set of strategic and operational objectives. Through our strong execution, we've delivered on nearly all of them, and we expect continued momentum as we close out the year. Our progress this quarter positions Guardant Health for sustained success in 2026, with continued oncology volume growth and strong Shield adoption. With that, we'll now open the call for questions. Thank you. We will now begin the Q&A session. If you would like to ask a question, please press star followed by one on your telephone keypad. If you'd like to remove your question, press star followed by two. Again, to ask a question, press star one. As a reminder, if you are using a speakerphone, please remember to pick up your handset before asking a question. During the Q&A session, we ask that you limit your questions to one question. Again, during this Q&A session, we ask that you limit yourselves to one question. We will pause here briefly as questions are registered. The first question comes from the line of Bradley Bowers with Mizuho. You may proceed. Hey there. Thanks for the question. A strong performance across the businesses, but I'm going to focus on Shield here. I was wondering if you could walk us through kind of the Shield ASP dynamics exiting the year. You know, continued strong pricing. I don't think it's surprising given the ADLT pricing, but that $900 we're kind of exiting the year at. You know, it's supposed to walk down to $700 by 2028. I know there's some mixed implications there, but is it kind of a steady degradation? Is there a fallout expected as ADLT pricing kind of rolls off the initial phase at the end of this year? Any color on the phasing of that would be helpful. Thank you. Yeah, Brad, this is Mike. I can take that. Yeah, I mean, to break down what's in the Shield ASP, we have the Medicare rates at $1,495 that came into play at the start of the second quarter. We're also receiving really good payment from Medicare Advantage payers. When they're paying us, they're paying us at this $1,495 rate also. At the moment, the majority of our volume is skewed towards Medicare and Medicare Advantage. We have a tranche of commercial patients, and we're effectively getting paid more or less zero for those. As we look at over the next few years, we're very confident in the $1,495 ADLT rate going forward. In fact, we've just submitted our package back to Medicare on the data submission of the pricing over the last six months. That should help us maintain this $1,495 rate now, at least for the next two years. Going forward, we expect Medicare Advantage to continue to be strong. In fact, we would hope that it can get stronger than where it is today. The fluctuation over the next couple of years is going to be the percentage of commercial payer patients that we have and how quickly we can ramp up the commercial reimbursement there. We're assuming in 2028, there's just a higher proportion of commercial patients in the mix, and it's going to take us time to sort of establish that reimbursement rate. Overall, we're really happy with where the ASP is today, and we think it bodes well for as we go into 2026 and beyond. The next question is from the line of Doug Schenkel with Wolfe Research. You may proceed. Hey, good afternoon, and thank you for taking my question. Another question on Shield. You mentioned at the investor day, as well as in your prepared remarks, that potential American Cancer Society guideline inclusion later this year could set the stage for commercial coverage in, I think, at least 10 states. We believe Anthem and other large blues are watching closely. To the best of our knowledge, the American Cancer Society concluded their CRC screening guideline review earlier this month. With that in mind, is guideline inclusion at this point a real possibility by year-end with the American Cancer Society? Once guidelines are in place, how long do you think it's going to take for that to translate into you actually getting paid? The final component of the question is, beyond those initial 10 or so states, there are other states like Florida and Louisiana where mandates have been brought in to include the American Cancer Society as well as NCCN in addition to USPSDF. If we think about that broader universe of states, which I think maybe gets you closer to 17, is it likely that reimbursement could occur not just in the initial 10, but closer to 20 over the next year or so? Thank you. Thank you, Doug, for your question. Yeah, you know, based on what we know, it appears that the American Cancer Society research team is almost done with their work. We remain confident about this potential for Shield to be included in the near future. We are monitoring the situation very closely, and we are very optimistic about that. In terms of the guide, like, you know, it's not part of this year guide. We are not counting on any kind of upside associated with the American Cancer Society guideline, and you know, it's going to take some time. When we go into the guideline, it gives us initially some upper hand, and it should have a strong, well, it should have a positive impact on our appeal success rate initially. At some point, you know, that would result in broadened coverage and contracting successes. I'm proud of what our team has achieved so far on trying to broaden access to Shield. You noticed Florida now, you know, through a consortium of supporters of making sure that innovative technology becomes accessible. For instance, Medicaid patient population in Florida have access to tests like Shield, and we are very proud of that. In general, we are very pleased with some of the positive and regular dialogue that even we have with the administration about their priorities around cancer screening, around prevention, around making America healthy. I'm excited that it looks like both President and Secretary are looking for ways to see how maybe the rate of cancer can get reduced in the country and how we could try to bring innovations to patients in a faster way. We'll see what happens. Obviously, we are not counting on any of those successes in our guide at this time. The next question comes from the line of Puneet Souda with Leerink Partners. You may proceed. Yeah, hi. Thanks for taking my questions. Really impressive quarter here and really strong guide. If I may, AmirAli, first one on Shield. Growth is accelerating on volumes, rightfully so. New product and ASP is also up. How should we think about 2026 growth for Shield and any early reception details that you can talk about on the MSED side, what's sort of the early attach rate? For Helmy, you know, it's been almost a decade since you launched G360 when it appeared on the market for the first time. It's really impressive to see 10 years later, this product is growing 30% plus. Maybe just talk to us about what's behind that and how should we think about the growth going forward here for the Liquid G360, which has been impressive. Thank you. Maybe I make the Shield part quick so Helmy can talk about the oncology side. As you've seen, we consistently raise our outlook throughout this year. We are very pleased with what we are seeing, the momentum that we are seeing. We want to be thoughtful and not get ahead of our skis. I think still it's too early for us to comment about 2026. At the right time, we would talk about it, but we continue to be very confident about the long-term outlook that we shared in our investor day. Yeah, no, we're very pleased with the performance in such 11 years and counting from when we launched Guardant360. To see it grow at this rate, I think at this point in the product cycle is really pleasing. I think it is sort of what we expected in the sense that many people think of this as a test and they pattern match it to other tests in the market. It truly is an application platform. When you think about these smart apps that we're introducing and really the multiplication of clinical utility and ability and capabilities of this platform, this is just the beginning in terms of where liquid biopsy can go. That is the point of liquid biopsies. You can come in, you can test many more patients, you can increase access, but you can test them longitudinally as well. We're still at the very, very early innings in terms of where this can go, where this technology can go just in oncology. I think you're going to see a lot more of this trajectory in the coming years as we continue to expand on the capabilities of Guardant360 over the next decade. Next question comes from the line of Subbu Nambi with Guggenheim. You may proceed. Thank you for taking my question. If you were to put a timeline, if we were to put a timeline to MCD FDA approval based on Shield trajectory next year, would FDA submission for MCD in late 2027 be a reasonable expectation? For Shield MCD, we just actually brought in access and we just actually started getting access to this kind of clinical data that I talked about during our investor day and the pre-approved remark. We need to monitor it and see how quickly we can build that evidence. We are very optimistic that potentially through the way that we are doing, we can get access to hundreds of thousands of patient data and monitor actually the impact of Shield MCD testing in the clinical value, performance, safety. It's still too early for us to specifically put a timeline for FDA approval. We would monitor the situation closely, and as we get more confidence, maybe we can talk about it at the right time. Thank you, guys. The next question comes from the line of Patrick Donnelly with Citi. You may proceed. Hey, guys. Thank you for taking the questions. Helmy, maybe one for you on Reveal. I know in the past you've talked about driving the test per patient higher. Can you just talk about the traction there, given the bigger push internally? What kind of progress you're seeing? Where can that go over the relative near term? I know during the prepared remarks you talked about, obviously, the ongoing studies, the additional tumor types. Can you just talk about what we should be looking for and the key catalysts on the Reveal side here over the next couple of quarters to keep an eye on? Thank you. Yeah, great question. I think we said at the beginning of the year, as we got the surveillance indication from a reimbursement point of view for Reveal, that we'd be turning on a lot of the sort of capabilities to be able to pull in subsequent test orders and so on. I'm pleased to report that we've put a lot of those in place and we're seeing some of the benefits of that and the return on investment there. We know we can pull in subsequent orders now in a very straightforward way. That is going to pay dividends across our blood-based portfolio as we think about the emergence and really the place where longitudinal testing will sit in terms of management of patients in oncology with things like Serena 6 in terms of ESR1, with the upcoming launch of our therapy monitoring based on Reveal, and obviously with the Reveal itself in the MRD setting, recurrence monitoring setting. Really great progress. The number of tests per patient has gone up pretty nicely. We're still, I would say, very much in the early cycles of really capitalizing on that investment. The next question comes from the line of Tycho Peterson with Jefferies. You may proceed. Hey, thanks. I would love to hear your views on the Pegasus data and just kind of how you think about that, you know, having kind of any impact on just MRD-driven therapy management and how you think about clinical utility evidence in general and NCCN guidelines. Yeah, you know, Pegasus was a really interesting study. It was a phase two signal-finding study. I think there are a few things that showed that I think were exciting to me, which is the fact that you could spare something like 75% of patients from chemotherapy, which meant a huge, huge reduction in terms of neurotoxicity and other toxicities related to such really harsh chemotherapy. I think Pegasus was based on our previous version of Reveal. I think we're really looking forward to Track C, which is based on a newer version. Really the field, you know, having larger data sets to really understand exactly where the threshold should be in terms of escalation and de-escalation in terms of patients. I think it's clear that I think there can be a lot of benefit by using this additional data in terms of ctDNA in the adjuvant and surveillance settings. I think this is a good foundation and one that we can build on as we continue investing in both clinical validity and clinical utility studies around our Reveal platform. The next question comes from the line of Bill Bonello with Craig Hallum. You may proceed. Hey, guys. I just want to push a little deeper on Sunit's third question about the growth in Guardant360. Could you just give us some sense today? I mean, if we think about, you know, what's out there that's driving, there's the underlying growth, there's the fact that you are probably taking share. I'm also curious about sort of where we stand today in terms of, you know, a paradigm shift to liquid first or perhaps to combination testing with liquid and solid tumor. To what extent are we seeing some of the repeat testing that you're talking about or the use of 360 for monitoring? Just trying to get a sense of, you know, what inning we're at in terms of some of these new growth drivers and how much of that is still in front of us. Great question. We're still very early, even in the penetration of liquid biopsy in terms of one test per lifetime. Given the capabilities of Guardant360 right now, they're just kind of mind-blowing to a lot of physicians in terms of the depth, the sensitivity, the application space. We see that growth in just that initial setting. That means not only market growth, but we're seeing, from what we can see, significant share gains as well as a result. There are other growth drivers we're seeing. The fact that concurrent testing will likely become the standard of care, both tissue and liquid, is also another sort of growth driver, and we're starting to see that really take off. Finally, the tests per patient. We estimate at maturation that we should be able to go from one test per patient per lifetime to something like 4.5 or 4 or 5 tests per patient per year, which obviously means more than, probably a doubling of where the market is today. Sorry, more than a 10x in terms of where the market is today. That's really exciting in terms of where things are going. This is things like Serena 6 in terms of ESR1, longitudinal monitoring, therapy monitoring, the data that we have with IO monitoring, with chemo monitoring, and so on. All of that will feed into essentially establishing this new paradigm of essentially monitoring patients with ctDNA. We're already seeing our biopharma partners use this type of testing in their phase one, phase two, phase three studies, using it to decide, do they sort of scale phase ones to phase two, using it for dosing. That's the other piece that I think is not very well appreciated, is that a lot of tests, you launch them, they're used exactly the same way 10 years later, 15 years later, and so on. They only have sort of one function. The application space and utility of how you use something like Guardant360 and Guardant Reveal is really multiplying quarter by quarter and year by year. This is a true platform. That word is often overused, but this is a true platform. You're seeing what that means in terms of our volume growth and the trajectory that we laid out at our investor day. The next question comes from the line of Michael Reiskin with BofA Securities. You may proceed. Hi, thank you for taking the question. This is Aaron on for Mike. I wanted to dive into Reveal volumes and specifically Reveal versus Ultra and how you guys are thinking about the R&D investment needed in both of those assets. The second part of that is, you know, MRD is still a fairly open space, you know, 10% penetrated, what people are saying. I guess how are you guys looking at the market? How are you guys looking at, you know, growth and how should we be expecting both of those assets to grow over the next, you know, three years? Thank you. Yeah, we're very excited about our MRD franchise. Reveal is the leading tissue-free MRD test in the market. We know that there'll be essentially two parts of the market that'll be important: the tissue-free side and the tumor-informed side of things. We're very pleased in terms of where we sit on the tissue-free side. It's our fastest growing product in oncology. The amount of data, the amount of investments, we have a 10x sort of data generation planned as we presented before next year. That flywheel is really sort of chugging away. We're excited about that trajectory. In terms of the tumor-informed side, I think we agree with you. There's kind of a lot of opportunity there in terms of a test that can really hit the needs of both biopharma and clinicians in terms of the sensitivity that is really required for that setting. We're just very pleased with the technology that we've developed. If you think about it, just everything we've built as a company is at a really nice point. The fact that we're really chugging away on our tissue volumes and the capabilities we have with using very low amounts of input material, very fast turnaround times, the sensitivity we have on the liquid biopsy side, and the capabilities in terms of bogs down and the speed to results, all of that is coming together in Reveal Ultra. I think it's going to be a product that will frankly blow everyone away once we launch it. We're excited for that and making really good progress. The next question comes from the line of Daniel Markowitz with Evercore ISI. You may proceed. Daniel, your line may be muted. Our next question comes from the line of Mark Massaro with BTIG. You may proceed. Hey, guys. Thanks for taking the questions. The first one is for you, AmirAli. Just looking at the Shield, it's great to see this trajectory. Is it reasonable to think in the near term that 1,000 sequential increase from the prior quarter is the right way to think about this? Just looking at the Q4 implied guide at the high end, it's plus nine. You just did plus eight. Prior quarter, plus seven. I guess I'm asking if this is a reasonable run rate in the near term, or do you think there's obviously upside from the partnerships with Quest Diagnostics, Path Group, certainly guideline inclusion and potential DTC uplift? That's my first part. The second part is for Helmy. Helmy, can you just give us a sense for Reveal Ultra? I believe this is the tumor-informed that can go down to one part per million. Just give us a sense for maybe if you could clarify if that is commercially launched now and how we should think about the timing of CMS reimbursement and additional data readouts. Thanks. Thanks, Mark. In terms of sequential growth, like our guide, what has ended in the midpoint is like another 8,000 Q over Q growth in Q4. We are going to monitor the situation closely. We don't want to get ahead of our skis and see what's going to happen. For next year, we are going to talk about it at the right time. There are a bunch of catalysts still in front of us. This Quest Diagnostics Path Group collaboration should be a positive thing. Guideline inclusion is definitely a positive thing. Continuous build-out of our own commercial team as we continue to next year would be a positive thing. We are confident about the target that we put out there for 2028. We go at it one step at a time, and we are very excited to see what's going to happen in Q4. Yeah, in terms of Reveal Ultra, I think the nice thing is we built such strong capabilities around MRD. When you think about the R&D and all the clinical studies, tens of thousands of samples, and many of those we've actually retained tissue. It's actually not a very heavy investment for us to essentially leverage that to really come out with the sort of ultra technology, the tumor-informed technology we have. We're seeing really good data, really excited in terms of where this can go. In terms of the sensitivity, we think it can bring it down to a much lower level than exists in the field or frankly exists in the pipeline of companies we've seen out there. I would say that in terms of timing, we're keeping that close to the chest. Stay tuned, but making good progress. We wouldn't be talking about it if it wasn't something that was not in the too distant future. The next question comes from the line of Casey Woodring with J.P. Morgan. You may proceed. Great. Thanks for taking my questions. On the Shield performance in the quarter, maybe as a follow-up to Mark's question, can you provide any KPIs around maybe average testing frequency per physician and whether volumes are coming from new time CRC screeners? My second question here, Mike, if you can provide any color on gross margin for Shield and Reveal embedded in the updated guide of 64%- 65% for this year, that'd be helpful. Thank you. Yeah, maybe some KPIs. Actually, it's exciting that the breadth of ordering continues to increase Q over Q. The depth of ordering continues to be very strong. Once the accounts actually start using Shield and we go through activation, the depth of ordering is very solid, which is really an endorsement of how deep this market is and mainly how many unscreened cancer patients are out there in the accounts that we are going to. We are seeing their doctors, we are successfully leading them and so forth. The other KPI to share, which we are very excited about, is we continue to see very high adherence rates. When the doctors order this test, more than 90% of those get converted to a sample received in our lab, which really gives us a bunch of efficiencies in our SNM investments. Yeah, and on the gross margins, with Shield, in the prepared remarks, we mentioned that the Shield gross margin this quarter, Q3, was 55%. ASPs are close to $900, and our cost per test now is consistently lower than $500. We've made really great progress with Shield gross margins. On the Reveal side, we've made fantastic progress over the last sort of nine months or so. Just to break that out a bit, our ASPs for Reveal continue to be in the $600- $700 range. Since the start of the year, our Reveal cost per test is consistently below $500. We have a nice gross margin on Reveal. It's a little bit lower than the 55% we've got on Shield, but they're really what's helping drive our overall blended gross margin. We've seen the positive impact on that going from 63% in Q3 last year to 66%. I think good progress across the board with gross margins. The next question comes from the line of Kyle Mikson with Canaccord Genuity. You may proceed. Hey, guys. Thanks for the questions. Congrats on the quarter. On Reveal, is it still possible you get ADLT status and breast Medicare coverage by the end of this year? Is that more likely a 2026 milestone? Secondly, AmirAli, we had a competitor this week announce advanced autonomous sensitivity data for its colon cancer blood tests. The confidence interval lower bound was 15%, and the study had a lot of very small lesions. Just curious if you think that a test with AA materially higher than the 13% for Shield would pose a threat and you, like, you know, one day aim to improve upon your AA data. Yeah, I mean, ADLT status is still a work in progress. Obviously, with the government shutdown, it's sort of paused some of those discussions a little bit. We're still working on breast and IO. We've always said, you know, probably more likely early next year, and we're still, I think, on track for that. Regarding the data disclosures, obviously, we applaud anybody who's trying to contribute in this difficult area. This is a hard science area, and we feel very comfortable with our leadership position in our technology stack, our data, and what we are doing. We've seen similar results in this field now a few times. This is a hard field, it's a hard science field, and we believe we have the best tech stack, very innovative technology homebrew that gives us confidence. We have a three-year head start on CRC now, and probably even much longer on the multicancer side relative to some of these competitions. We feel very good with our position at this time. Definitely, there are some pipeline activities that we are working on. We'll see what happens there. The next question is from the line of Luke Sergott with Barclays. You may proceed. Great. Thanks for the questions. Just wanted to touch here on the step-up in OpEx that you guys have for the year and implied in 4Q. Really just kind of dig in where that spend, incremental spend is going and where you guys think from an S&M perspective, where you guys want to exit the year as a number of reps as you think about Shield and oncology and Reveal and kind of how that, if you're able to pull forward any of those costs given the success you've had in some of these and some of the other launches. Yeah. I mean, for the OpEx step-up, it's pretty much all in the sales and marketing line. I think we've been consistent throughout the year whereby we've said we're going to be reinvesting any incremental gross profit in screening back into the sales and marketing line to really drive that commercial build-out. We'll continue to do that. I think it's the biggest focus for us as we look to scale. We've said on the screening side, we've now got over 250 salespeople out in the field. That's a significant ramp up during the year. We'll continue to look at how we build that out. On the oncology side, it's a little bit larger than that. We've got a very sort of well-built-out commercial infrastructure with oncology. As we look forward and go into 2026, I think you should expect to see a similar ramp in the sales and marketing line. We're very focused in the R&D line and the G&A line at keeping them relatively flat. I think that's the plan for the next 12 months. The next question comes from the line of Dan Brennan with TD Cowen. You may proceed. Great. Thank you. Congrats on the quarter. Maybe just on Guardant360, just a couple. Maybe one for Mike and then one for Helmy. On the guide, I know the clinical oncology volume guide is now greater than 30. Does that contemplate a big step down from the, you know, the Guardant360 volume, which has accelerated tremendously year to date, obviously, from the Q3 30%? More so for Helmy, I know you've given a lot of color on the excitement over the kind of outlook for Guardant360, but could you give a little more color on the acceleration you've seen year to date? Is it more share gains, which you talked about? Are you seeing hospitals consolidate? Do you think it's more just penetration of CGP, or do you think it's more like this test per patient pickup? Any way you can kind of dissect a little bit of this really strong acceleration? Thank you. Maybe I'll just start on our Q4 guide. We had a great Q3. I think our guide for Guardant360 volume and for overall oncology volume implies sequential growth in Q4. It implies a very strong year-over-year growth in volume. If you back into it, it's over 30% year-over-year growth in Q4. I think we've just continued to expect the momentum that we saw in Q3 continuing to Q4. I think for us, things are looking very, very strong as we get towards the end of the year. Yeah, in terms of growth driver, I think what you're seeing really is the fact that it's just a very compelling test from a value proposition. I think a lot of what you're seeing is some of the share gains from the sort of other tests in the market, from other hospitals and so on. That's been exciting. We're seeing a little bit of the sort of increase in testing in terms of longitudinally, but I would say that's a very minor part. I think that's still another major growth catalyst for us in the future that we haven't really tapped into. The third piece is, this test has so many capabilities, things like being able to determine the type of cancer, what someone who has a cancer of unknown primary, subtyping. If you think about the long tail of cancers where liquid biopsies and even tissue tumor biopsies aren't really utilized, the fact that we have this smart platform with epigenetics and so on that can give so much more insight into tumor biology, I think you're seeing penetration into some of these longer tail of cancers as well. One more question, please, Cameron. Our last question comes from the line of Dan Arias with Stifel. You may proceed. Yeah, good afternoon, guys. Thanks. Helmy, I just wanted to go back to Reveal. Can you maybe talk about where things are on the commercial side when it comes to reimbursement and colorectal? What's a good ballpark number at this point for just the percentage of tests that are getting paid for? I guess stage two and three patients would be the right subpopulation to ask about there. I'm really just trying to understand the emerging side of CMS in your key indication there. Yeah, again, it's Mike here, and it cut out a bit towards the end, but I think you're asking about Reveal reimbursements with CRC. CRC now is roughly 50% of our volume. It continues to be at that sort of level, the rest being made up at the moment from breast and lung. Where we are getting reimbursed is for all of the, now whenever we run a CRC test, we're getting reimbursed for all of the tests that we do for Medicare, and that's at the $1,640 rate. We're getting good pull-through with Medicare Advantage. We're starting to see traction with commercial payers. That's improving all of the time. I think we're feeling good at where the reimbursement level is. As we look forward, we think there's continuous runway with Reveal, more and more Medicare Advantage and commercial payments on the CRC side. As we just mentioned, we're anticipating Reveal breast reimbursement. We've submitted the data package to MolDx for Reveal IO, and hopefully going forward, we're getting incremental Medicare reimbursement and incremental reimbursement from all of the payers as we move into 2026. That was our last question. That concludes today's call. Thank you for your participation and enjoy the rest of your day.
