Helmy Eltoukhy: A 60-year-old man had gone his entire life without being screened for colorectal cancer, despite repeated recommendations from his physician each year to undergo a colonoscopy. Although he agreed to stool-based testing on several occasions, the kits were never completed once they arrived at his home. During a routine office visit, the patient was offered a Shield blood test, which he agreed to, and the test was completed that same day in the office. The Shield result was positive, which motivated the patient to undergo his very first colonoscopy, following his physician's recommendation. The colonoscopy identified stage 1 colon cancer, and the patient was quickly scheduled for surgery. Because the cancer was caught early, he has been informed that his treatment is likely curative.

As part of that process, we have rigorously evaluated dozens of external technologies over the years.

Speaker #2: We also expect to see benefits from our collaboration with Quest and Pat Group, alongside the continued expansion of our field force throughout the year.

Speaker #2: Additional growth drivers include ACS guideline inclusion, targeted direct-to-consumer campaign launches, and the expansion of sales-based Shield into select markets outside the US. Turning to slide 19.

Speaker #2: We continue to invest aggressively in R&D to improve our product performance. As part of that process, we have rigorously evaluated dozens of external technologies over the years.

Speaker #2: We recently completed the acquisition of methocyte diagnostics, which brings a new technology in-house that is complementary to the SMART platform and also brings on an impressive team further strengthening our world-class R&D organization.

AmirAli Talasaz: We recently completed the acquisition of MetaCyte Diagnostics, which brings a new technology in-house that is complementary to the SMART Platform, and also brings on an impressive team, further strengthening our world-class R&D organization. We are excited for the technology's potential to enhance our CRC screening, multi-cancer detection, and ultimately, the entirety of our oncology product portfolio. It also has the potential to accelerate our multi-disease detection pipeline. With that, I will now turn the call over to Mike for more detail on our financials.

Speaker #2: We are excited for the technology's potential to enhance our CRC screening, multicancer detection, and ultimately the entirety of our oncology product portfolio. It also has the potential to accelerate our multidisease detection pipeline.

Speaker #2: With that, I will now turn the call over to Mike for more detail on our financials.

Speaker #1: Thanks, AmirAli. Turning to slide 20, our review select financial highlights for the quarter and full-year ended December 31, 2025. Unless otherwise noted, all growth rates are year over year.

Mike Bell: Thanks, AmirAli. Turning to Slide 20, I'll review select financial highlights for the quarter and full year ending 31 December 2025. Unless otherwise noted, all growth rates are year-over-year. Total revenue in the fourth quarter increased 39% to $281.3 million, reflecting strong execution across oncology, biopharma and data, and screening. Oncology revenue increased 30% to $189.9 million, driven by continued strong volume growth. We reported approximately 79,000 oncology tests in Q4, up 38%, demonstrating sustained momentum across the portfolio. Guardant360 liquid volumes increased nearly 30%, supported by expanding clinical utility from SMART apps launched over the past year, and Guardant360 Tissue remained strong following a major upgrade introduced in Q2.

Guardant360 liquid volumes increased nearly 30%, supported by expanding clinical utility from smart apps launched over the past year, and Guardant360 tissue remained strong following the major upgrade introduced in Q2.

Speaker #1: Reveal continued to be our fastest-growing oncology product, benefiting from CRC surveillance reimbursement and ongoing strength in breast and lung cancer. We were also encouraged by the early uptake of Reveal for late-stage therapy response monitoring, launched in Q4.

Mike Bell: Reveal continued to be our fastest-growing oncology product, benefiting from CRT surveillance reimbursement and ongoing strength in breast and lung cancer. We were also encouraged by the early uptake of Reveal for late-stage therapy response monitoring launched in Q4. Average selling prices were stable sequentially, with Guardant360 Liquid in the range of $3,000 to $3,100. Guardant360 Tissue, approximately $2,000, and Reveal between $600 and $700. As a reminder, we've submitted data packages to MolDX for Medicare reimbursement, covering breast MRD and both immunotherapy and chemotherapy response monitoring. Successful outcomes will provide upside to Reveal ASP. Biopharma and data revenue was $54.0 million, up 9%, which was in line with our expectations. Screening revenue totaled $35.1 million from approximately 38,000 Shield tests.

Speaker #1: Average selling prices were stable sequentially, with Guardant360 liquid in the range of $3,000 to $3,100, Guardant360 tissue approximately $2,000, and Reveal between $600 and $700.

Speaker #1: As a reminder, we've submitted data packages to Multi-X for Medicare reimbursement covering breast MRD and both immunotherapy and chemotherapy response monitoring. Successful outcomes will provide upside to Reveal ASP.

Speaker #1: Biopharma and data revenue was $54.0 million, up 9%, which was in line with our expectations. Screening revenue totaled $35.1 million, from approximately $38,000 Shield tests.

Speaker #1: Shield ASP was approximately $850, consistent with expectations and reflecting our focus on Medicare-covered patients. Out-of-period revenue totaled approximately $18 million, for the fourth quarter of 2025, including approximately $3 million related to screening.

Mike Bell: Shield ASP was approximately $850, consistent with expectations and reflecting our focus on Medicare-covered patients. Out-of-period revenue totaled approximately $18 million for the fourth quarter of 2025, including approximately $3 million related to screening. This was in line with prior periods, compared to approximately $17 million in both the third quarter of 2025 and the fourth quarter of 2024. For the full year, total revenue grew 33% to $982.0 million. Oncology revenue increased 26% to $683.6 million. We reported approximately 276,000 oncology tests, representing 34% growth. Guardant360 volume growth accelerated to 25% for the year, driven by continued Smart App adoption.

Speaker #1: This was in line with prior periods, compared to approximately $17 million in both the third quarter of 2025 and the fourth quarter of 2024.

Speaker #1: For the full year, total revenue grew 33% to $982.0 million. Oncology revenue increased 26% to $683.6 million. We reported approximately 276,000 oncology tests, representing 34% growth.

Speaker #1: Guardant 360 volume growth accelerated to 25% for the year, driven by continued SMART App adoption. Guardant 360 tissue volumes strengthened in the second half following the SMART platform upgrade, and Reveal remained our fastest-growing oncology product throughout the year.

Mike Bell: Guardant360 Tissue volumes strengthened in the second half following the SMART Platform upgrade, and Reveal remained our fastest-growing oncology product throughout the year. Biopharma and data revenue grew 18% to $210.1 million. Finally, screening revenue totaled $79.7 million in our first full calendar year since launch, generated from approximately 87,000 Shield tests. Turning to Slide 21. Non-GAAP gross margin improved to 66% in Q4, compared to 63% in the prior year. For the full year, non-GAAP gross margin increased to 66%, up from 62% in 2024. This improvement was primarily driven by a significant reduction in Reveal cost per test, which improved from over $1,000 in Q3 2024 to under $500 throughout 2025. We also made meaningful progress improving Shield gross margins.

Speaker #1: Biopharma and data revenue grew 18% to $210.1 million, finally screening revenue totaled $79.7 million, in our first full calendar year since launch, generated from approximately $87,000 Shield tests.

Speaker #1: Turning to slide 21, non-gap gross margin improved to 66% in Q4, compared to 63% in the prior year, for the full year, non-gap gross margin increased to 66%, up from 62% in 2024.

Speaker #1: This improvement was primarily driven by a significant reduction in Reveal cost per test, which improved from over $1,000 in Q3 2024 to under $500 throughout 2025.

Speaker #1: We also made meaningful progress improving Shield gross margins. Shield's non-GAAP gross margin improved from negative levels at launch to 52% in Q4 2025. This reflects strong ASPs under the Medicare ADLT rate.

Mike Bell: Shield's non-GAAP gross margin improved from negative levels at launch to 52% in Q4 2025. This reflects strong ASPs under the Medicare ADLT rate, disciplined focus on reimbursable testing, and continued volume-driven cost reduction. Shield cost per test declined sequentially and exited the year at approximately $450, in line with our operational plan. Non-GAAP operating expenses were $260.0 million in Q4, up 21%, and $903.7 million for the full year, up 19%. Full-year operating expense was modestly above guidance due to two Q4 items. Firstly, an increase in accrual for the 2025 company bonus plan, which reflects the strong performance in the year across financial, regulatory, and commercial milestones. Secondly, the continued reinvestment of incremental screening gross profit into sales and marketing to accelerate our commercial build-out.

Speaker #1: Disciplined focus on reimbursable testing and continued volume-driven cost reduction. Shield cost per test declined sequentially and exited the year at approximately $450, in line with our operational plan.

Full-year operating expense was modestly above guidance due to two Q4 items, firstly an increase in accrual for the 2025 company bonus plan, which reflects the strong performance in the year across financial, regulatory, and commercial milestones.

Speaker #1: Secondly, the continued reinvestment of incremental screening gross profit into sales and marketing to accelerate our commercial build-out. Adjusted EBITDA loss improved to $64.9 million in Q4, compared to $78.4 million in the prior-year quarter.

Mike Bell: Adjusted EBITDA loss improved to $64.9 million in Q4, compared to $78.4 million in the prior year quarter. For the full year, adjusted EBITDA loss improved to $220.9 million versus $257.5 million in 2024. Turning to slide 22. We continued to improve cash performance in 2025. Free cash flow burn was $233 million for the year, an improvement of $42 million, and in line with our guidance. Importantly, excluding screening, the core business generated positive free cash flow in both Q3 and Q4. We expect the core business to be free cash flow positive for the full year 2026, and remain committed to achieving company-wide cash flow breakeven by the end of 2027.

Speaker #1: For the full year, adjusted EBITDA loss improved to $220.9 million, versus $257.5 million in 2024. Turning to slide 22, we continue to improve cash performance in 2025.

Speaker #1: Free cash flow burn was $233 million, for the year, an improvement of $42 million, and in line with our guidance. Importantly, excluding screening, a core business generated positive free cash flow in both Q3 and Q4.

Speaker #1: We expect the core business to be free cash flow positive for the full year 2026, and remain committed to achieving company-wide cash flow breakeven by the end of 2027.

Speaker #1: As AmirAli mentioned, in December, we acquired Metasite for $59 million in upfront cash, plus up to $90 million in contingent consideration tied to future commercial and regulatory milestones.

Mike Bell: As Ami already mentioned, in December, we acquired MetaCyte for $59 million in upfront cash, plus up to $90 million in contingent consideration tied to future commercial and regulatory milestones. We believe this technology enhances our existing product portfolio and accelerates our multi-disease detection pipeline. Following the MetaCyte acquisition and our November equity and convertible debt financing, we ended the year with approximately $1.3 billion in cash, providing sufficient runway to fund our growth initiatives and reach company-wide cash flow breakeven. Turning to slide 23. We enter 2026 with solid momentum across the business and increasing visibility into our growth drivers. For full year 2026, we expect revenue to be in the range of $1.25 to 1.28 billion, representing growth of 27% to 30%.

Speaker #1: Turning to slide 23, we entered 2026 with solid momentum across the business and increasing visibility into our growth drivers. For full year 2026, we expect revenue to be in the range of $1.25 to $1.28 billion, representing growth of 27 to 30 percent.

Speaker #1: This outlook reflects sustained strength in oncology and accelerating expansion in screening, firmly positioning us to achieve our 2028 long-range revenue target of $2.2 billion.

Mike Bell: This outlook reflects the same strength in oncology and accelerating expansion in screening, firmly positioning us to achieve our 2028 long-range revenue target of $2.2 billion. We expect oncology revenue growth of 25% to 27% in 2026, supported by volume growth of approximately 30%. We believe demand fundamentals remain strong across the portfolio. Guardant360 should continue to benefit from adoption of SMART apps, and Guardant360 Tissue growth should continue to build on the SMART platform upgrade and continued strong commercial execution. Reveal is expected to remain our fastest-growing oncology product, driven by MRD and therapy monitoring. Note that our oncology guidance does not include potential upsides during the year from SERENA-6 ESR1 monitoring, FDA approval of Guardant360 CDx, and the launch of Reveal Ultra.

Speaker #1: We expect oncology revenue growth of 25 to 27 percent in 2026, supported by volume growth of approximately 30%. We believe demand fundamentals remain strong across the portfolio. Guardant 360 liquid should continue to benefit from adoption of smart apps, and Guardant 360 tissue growth should continue to build on the SMART platform upgrade and continued strong commercial execution.

Speaker #1: Reveal is expected to remain our fastest-growing oncology product driven by MRD and therapy monitoring. Note that our oncology guidance does not include potential upsides during the year from SerenaSIX ESR1 monitoring, FDA approval of Guardant 360 liquid CDX, and the launch of Reveal Ultra.

Speaker #1: For biopharma and data, we're encouraged by recent strategic partnerships and the strength of our CDx pipeline. For 2026, we're forecasting low double-digit revenue growth, supported by both ongoing collaborations and new program starts.

Mike Bell: For biopharma and data, we're encouraged by recent strategic partnerships and the strength of our CDx pipeline. For 2026, we're forecasting low double-digit revenue growth, supported by both ongoing collaborations and new program starts. We expect screening revenue to be in the range of $162 to 174 million, driven by 210,000 to 225,000 tests, a meaningful growth from approximately $80 million revenue and 87,000 tests in 2025. As in 2025, we expect sequential increase in Shield volumes every quarter, with the increases expected to be greater towards the back half of the year. This reflects early year seasonality at PCP offices, the ramping productivity of our growing number of sales reps, and the expansion of EMR capability through our Quest and PathGroup collaborations.

Speaker #1: We expect screening revenue to be in the range of $162 to $174 million, driven by $210,000 to $225,000 tests, a meaningful growth from approximately $80 million revenue and $87,000 tests in 2025.

Speaker #1: This reflects early-year seasonality at PCP offices, the ramping productivity of our growing number of sales reps, and the expansion of EMR capability through our Quest and PathGroup collaborations.

Speaker #1: Note that our screening guidance does not include potential upsides from Quest co-promotion activities, as well as ACS guideline inclusion, which we continue to expect in the near future.

Mike Bell: Note that our screening guidance does not include potential upside from Quest co-promotion activities, as well as ACS guideline inclusion, which we continue to expect in the near future. We continue to make steady progress improving gross margins across our products through ASP optimization, workflow efficiencies, transition to NovaSeq X, and disciplined cost management. For 2026, we expect non-GAAP gross margins to be in the range of 64% to 65%, reflecting ongoing operational improvements, volume growth, and expected product mix. We expect non-GAAP operating expenses of $1.03 to $1.05 billion, representing 14% to 16% growth year over year. We anticipate continued operating leverage as revenue growth outpaces expense growth. R&D and G&A are expected again to remain relatively stable, with incremental investment primarily directed towards screening, sales, and marketing. Finally, we remain focused on reducing cash burn each year.

Speaker #1: We continue to make steady progress improving gross margins across our products through ASP optimisation, workflow efficiencies, transition to NovaseqX, and disciplined cost management. For 2026, we expect non-gap gross margin to be in the range of $64 to $65 percent, reflecting ongoing operational improvements: volume growth and expected product mix.

Speaker #1: R&D and G&A are expected again to remain relatively stable, with incremental investment primarily directed towards screening, sales, and marketing. Finally, we remain focused on reducing cash burn each year.

Speaker #1: For 2026, we expect free cash flow burn of $185 to $195 million, an improvement from 2025. Excluding screening, we expect the remainder of the business to be free cash flow positive for the full year.

Mike Bell: For 2026, we expect free cash flow burn of $185 to 195 million, an improvement from 2025. Excluding screening, we expect the remainder of the business to be free cash flow positive for the full year. Finally, turning to slide 24. Looking ahead, we have a rich set of catalysts across our business that will drive continued growth. In oncology, we expect to launch several new products, including Guardant360 Liquid CDx for lung FDA approval, our ESR1 monitoring test, and Reveal Ultra. In addition, we expect to release additional apps driven by our SMART platform and advanced reimbursement across multiple indications for Reveal. In biopharma and data, we expect new CDx approvals, as well as additional strategic biopharma and Infinity AI data partnerships.

Speaker #1: Finally, turning to slide 24, looking ahead, we have a rich set of catalysts across our business that will drive continued growth. In oncology, we expect to launch several new products, including Guardant 360 liquid CDX following FDA approval, our ESR1 monitoring test, and Reveal Ultra.

Speaker #1: In addition, we expect to release additional apps driven by our SMART platform and advanced reimbursement across multiple indications for Reveal. In biopharma and data, we expect new CDx approvals as well as additional strategic biopharma and Infinity AI data partnerships.

Speaker #1: In screening, we look forward to inclusion in ACS guidelines in the near future, driving commercial expansion with Quest and expanding self-pay Shield outside the US.

Mike Bell: In screening, we look forward to inclusion in ACS guidelines in the near future, driving commercial expansion with Quest and expanding self-pay Shield outside the US. With that, we'll now open the call for questions.

Speaker #2: The first question comes from the line of Dan Leonard with UBS. May I proceed?

Speaker #3: Thank you very much. I'd like to talk a little bit about Reveal Therapeutic monitoring. Helmi both you and Mike commented on that in your prepared remarks.

Dan Leonard: Thank you very much. I'd like to talk a little bit about Reveal therapeutic monitoring. Helmy, both you and Mike commented on that in your prepared remarks. Could you elaborate further on how you're framing that opportunity, both for Reveal volumes as well as for Guardant360 volumes as well? Thank you.

Speaker #3: Could you elaborate further on how you're framing that opportunity, both for Reveal volumes as well as for Guardant360 volumes as well? Thank you.

Speaker #4: Yeah, we're very excited about Reveal for therapy monitoring. We think it's an important opportunity to really solidify and work centergistically with Guardant 360. If you think about it, all the volume we have with 360 patients are being tested in terms of therapy selection, and then this idea of coupling that with Reveal for essentially monitoring how those patients are doing on therapies is really exciting.

Helmy Eltoukhy: Yeah, we're very excited about Reveal for therapy monitoring. We think it's an important opportunity to really solidify and work synergistically with Guardant360. If you think about it, you know, all the volume we have with, you know, Guardant360, patients are being tested in terms of therapy selection. And then, you know, this idea of coupling that with Reveal for essentially monitoring how those patients are doing on therapies is really exciting. And then the nice thing about that is, you know, unfortunately, as some of those patients progress, they're gonna need a new therapeutic decision in terms of, you know, hopefully a next-generation drug or a next-line therapy that can be applied to them.

Speaker #4: And then the nice thing about that is, unfortunately, some of those patients progress, they're going to need a new therapeutic decision in terms of hopefully next-generation drug or next-line therapy that can be applied to them.

Speaker #4: And so Reveal for therapy monitoring really bridges to that next Guardant 360 test. And we have a very unique platform and portfolio that allows these tests to work together.

Helmy Eltoukhy: And so Reveal for therapy monitoring really bridges to that next Guardant360 test, and we have a very unique platform and portfolio that allows these tests to work together. And so I would say that when we get some of the reimbursement wins for IO monitoring and chemo monitoring, this could be a very important driver for growth over the next few years for the oncology business.

Speaker #4: And so I would say that when we get some of the reimbursement wins for IO monitoring and chemo monitoring this could be a very important driver for growth over the next few years, for the oncology business.

Speaker #3: Thank you very much.

Dan Leonard: Thank you very much.

Operator: The next question comes from the line of Puneet Souda with Leerink Partners. You may proceed.

Speaker #2: The next question comes from the line of Puneet Sooda with Leering Partners. You may proceed.

Puneet Souda: Yeah. Hi, guys. Thanks for taking my questions. The first one, Helmy, for you. When you look at the strong growth that you've seen in oncology, maybe could you elaborate, you know, how should we think about that throughout the year and both in G360 versus Reveal? How should we think about the growth of those products? Because, you know, important drivers like the chemo-resistant launch and other things that you've mentioned are actually still not in the guide. So just trying to think about, you know, sort of how should we think about both of these products, you know, volume growth throughout the year.

Speaker #5: Yeah, hi guys. Thanks for taking my question. So first one, Helmi for you. When you look at the strong growth that you've seen in oncology, maybe could you elaborate how should we think about that throughout the year and both in G360 versus Reveal?

Speaker #5: How should we think about the growth of those products? Because important drivers like the CAMI systems launch, and other things that you've mentioned are actually still not in the guide.

Speaker #5: So just trying to think about sort of how should we think about both of these products volume growth throughout the year.

Speaker #4: Yeah, maybe I'll start, and I'll Mike sort of jump in. We're very bullish about 26 in terms of the progress we've made in 25 and what we're seeing at the beginning of the year here.

Helmy Eltoukhy: Yeah, maybe I'll start, and, Mike, sort of, jump in. We're very bullish about 2026 in terms of the progress we've made in 2025 and what we're seeing at the beginning of the year here. So, you know, I would say that we think it's gonna be another strong year for Guardant360. You know, something around at least 20% growth in terms of volumes. And then obviously, another very strong year for Reveal. It'll continue to be our fastest-growing product. We think we'll see some acceleration, obviously, with Reveal for therapy monitoring as well and on top of that. So, you know, I think we're well underway for our sort of LRP Investor Day projections in 2028.

Speaker #4: So I would say that we think it's going to be another strong year for 360—something around at least 20% growth in terms of volumes, and then obviously another very strong year for Reveal.

Speaker #4: It'll continue to be our fastest growing product. We think we'll see some acceleration, obviously, with Reveal for therapy monitoring as well on top of that.

Speaker #4: So I think we're well underway for our sort of LRP investor day projections in 2028.

Speaker #6: Yeah, well, maybe just to add because we didn't talk about tissue, I think in the back half of 25, we saw a nice acceleration with Guardant 360 tissue following the SMART upgrades that we did back in May of last year.

Mike Bell: Yeah, well, maybe just to add, because we didn't talk about tissue. I think, you know, in the back half of 2025, we saw a nice acceleration with Guardant360 Tissue following the SMART upgrades that we did back in May of last year. And so I think that also as we look forward in 2026, we continue to expect tissue to accelerate. We think there's getting the FDA approval for Guardant360 during the year, you know, also could potentially have a pull-through impact on Guardant360 Tissue as well. So, yeah, we're feeling bullish about all of the products across oncology.

Speaker #6: And so I think also as we look forward in 2026, we continue to expect tissue to accelerate within those getting the FDA approval for Guardant 360 during the also could potentially have a pull-through impact on Guardant 360 tissue as well.

Speaker #6: So yeah, we feel the bullish about all of the products across oncology.

Operator: The next question comes from the line of Doug Shankle with Wolfe Research. You may proceed.

Operator: The next question comes from the line of Doug Schenkel with Wolfe Research. You may proceed.

Speaker #2: The next question comes from the line of Doug Schenkel with Wolfe Research. You may proceed.

Speaker #7: Hi, good afternoon, and thank you for taking my questions. Both are on Shield, and they're related. It's really great to hear that you are expecting to be free cash flow positive in 2026, excluding Shield.

Doug Schenkel: Hi, good afternoon, and thank you for taking my questions. Both on Shield, and they're related. It's really great to hear that you are expecting to be free cash flow positive in 2026, excluding Shield. I'm curious what you're thinking in terms of Shield-specific burn. I think you've provided color on that in the past, and I guess kind of building off of that, I believe you exited 2025 with approximately 300 Shield-focused reps. How should we be thinking about the pacing of rep hiring throughout 2026? And, you know, where do you think the sales force should be at year-end? Thank you very much.

Speaker #7: I'm curious what you're thinking in terms of Shield specific burn. I think you've provided color on that in the past, and I guess kind of building off of that, I believe you exited 2025 with approximately 300 Shield-focused reps.

Speaker #7: How should we be thinking about the pacing of rep hiring throughout 2026? And where do you think the sales force should be at year-end?

Speaker #7: Thank you very much.

Speaker #4: Hi, Steve. I'll start with that.

AmirAli Talasaz: Mike, do you want to start? Good day.

Speaker #6: Yeah, yeah, I can start on the question on screening burn. Doug, yeah, no, for 25, again, our overall burn for the company was 233 million.

Mike Bell: Yeah. Yeah, I start on the question on screening burn, Doug. Yeah, no, for 25, you know, again, our overall burn for the company was $233 million. Of that, roughly around $220 million was screening. You know, we sort of set a target of $200 million. Actually, we pushed quite hard on that, particularly towards the end of the year. We're really wanting to take advantage of our first mover position. And, you know, we mentioned again on the call that excluding screening, the rest of the business was actually cash flow free cash flow positive for Q3 and Q4.

Speaker #6: Of that, roughly around 220 million was screening. We sort of set a target of 200 million. Actually, we pushed quite hard on that, particularly towards the end of the year.

Speaker #6: We really wanted to take advantage of our first mover position. And we mentioned again on the call that excluding screening, the rest of the business was actually cash flow, free cash flow positive for Q3 and Q4.

Mike Bell: For 2026, we think a similar level of burn on screening as 2025, so around that sort of $220 million mark. Again, you know, we're gonna be making heavy investments on the commercial side, really building out the infrastructure. And we still expect 2026 to be a year of investment for screening and then 2027 to be a year of inflection, where we start to get a lot of operating leverage on that commercial infrastructure that we're building. Maybe just to, you know, point out one other thing, you know, we again set our whole company free cash flow guidance, $185 to $195 million burn.

Speaker #6: For 26, we think a similar level of burn on screening as 25. So around that sort of 220 million mark, again, we're going to be making heavy investments on the commercial side, really building out that infrastructure.

Speaker #6: And we still expect '26 to be a year of investment for screening, and then '27 to be a year of inflection where we start to get a lot of operating leverage on that commercial infrastructure that we build. And maybe just point out one other thing.

Speaker #6: Again, we set our whole company free cash flow guidance 185 to 195 burn. So that's implying that the rest of the business now is strongly cash flow positive in 2026.

Mike Bell: So that's implying that the rest of the business now is strongly cash flow positive in 2026, you know, as a sort of midpoint of that guidance around $30 million positive cash flows. So, yeah, we're feeling really good about how we're sort of managing the burn.

Speaker #6: As a sort of midpoint of that guidance, around 30 million positive cash flow. So yeah, we're feeling really good about how we're sort of managing the burn.

Speaker #5: And in terms of commercial infrastructure and field force, we are very excited. We're a very powerful commercial platform that we built in 2025. And we are going to continue to build out that commercial organization in 2026.

AmirAli Talasaz: In terms of commercial infrastructure and field force, we are very excited with a very powerful commercial platform that we built in 2025, and we are gonna continue to build out that commercial organization in 2026. I'm not gonna get into the specifics of maybe exact headcount of the field force, but maybe just to give you some direction and color, the way that you can think about it, we will continue to invest our incremental gross profit that we are gonna generate this year into further build-out of our commercial infrastructure on both sales and marketing, and majority would go still in building sales force and hiring more people.

Speaker #5: I'm not going to get into the specifics of maybe exact headcounts of the field force, but maybe just to give you some direction and color, the way that you can think about it, we will continue to invest our incremental gross profit that we are going to generate this year into further build-outs of our commercial infrastructure on both sales and marketing and majority would go still in building sales force and hiring more people.

Speaker #7: Great. Thank you very much.

Doug Schenkel: Great. Thank you very much.

Operator: The next question comes from the line of Tycho Peterson with Jefferies. You may proceed.

Speaker #2: The next question comes from the line of Tycho Peterson with Jefferies. You may proceed.

Speaker #8: Hey, thanks. Want to start off on one of the bigger topics on ADLT pricing. What is your latest thinking and what have you baked into the guide, if anything, for G360?

Tycho Peterson: Hey, thanks. Want to start off on, you know, one of the bigger topics on ADLT pricing. You know, what is your latest thinking, and what have you baked into the guide, if anything, for Guardant360? And then, you know, overall, you are guiding for a decel in volumes and on revenue in oncology. Presumably some conservatism there. There's a lot you didn't bake in, but where do you think kind of the most conservatism is in the outlook on oncology?

Speaker #8: And then overall, you are guiding for a desale and volumes and revenue and oncology presumably some conservatism there. There's a lot you didn't bake in, but where do you think kind of the most conservatism is in the outlook on oncology?

Speaker #4: Yeah, in terms of ADLT, I think we're still on track in terms of FDA submission, making very good progress there. We think that hopefully gets through the finish line in the second half of this year.

AmirAli Talasaz: Yeah, in terms of ADLT, you know, I think we're still on track in terms of FDA submission, making very good progress there. We think that hopefully gets through the finish line in the second half of this year and then, you know, potentially sets up second sort of next ADLT pricing rate for 360 at the beginning of 2027. So nothing is baked in, in terms of ADLT pricing for 360, for 2026. In terms of the second part of your question, I would-

Speaker #4: And then potentially sets up a second, sort of, a next ADLT pricing rate for 360 at the beginning of '27. So, nothing is baked in in terms of ADLT pricing for 360 for 2026.

Speaker #4: In terms of the second part of your question, I was.

Mike Bell: Yeah, yeah, I mean, maybe on the volumes, you know, 25 was an incredibly, incredibly strong year, particularly with Guardant360 and, you know, just the, with the smart apps driving the volume, volume. But, you know, I think we look at, we look at 2026 as just, just continuing that, that trend. You know, our, our guide is, you know, 30% oncology volume growth. And so, you know, we think that's, that's incredibly strong. And again, you know, that's coming across all of the portfolio. Helmy, Helmy mentioned it earlier, but, you know, we, we still expect strong traction with Guardant360, Reveal being the, the fastest-growing product and, you know, tissue continuing to accelerate.

Speaker #6: Yeah, yeah, I mean, maybe on the volumes, 25 was an incredibly strong year. Particularly with Guardant 360 and just with the SMART apps. Driving the volume there.

Speaker #6: I think we look at 2026 as just continuing that trend. Our guide is 30% oncology volume growth. And so we think that's incredibly strong.

Speaker #6: And again, that's coming across all of the portfolio. Helmy mentioned it earlier, but we still expect strong traction with Guardant360, Reveal being the fastest growing product.

Speaker #6: And tissue continuing to accelerate. So yeah, I think we're feeling really positive. About the guide that we put out for oncology growth next year, or this year should have been.

Mike Bell: So, yeah, I think we're feeling really positive about the guide that we put out for oncology growth next year, or this year, I should have said.

Speaker #8: Okay, Mike, and then just to follow up on speaking of conservatism, you're also guiding for Shield ASPs to be down relative to where you exited 25.

Tycho Peterson: Okay, Mike, and then just to follow up, you know, on speaking of conservatism, you're also guiding for Shield ASPs to be, you know, down relative to where you exited 25. You know, what's the thought process there? And also, what are you baking in for international? I know you flagged that as incremental.

Speaker #8: What's the thought process there? And also, what are you baking in for international? I know you flagged that as incremental.

Mike Bell: Yeah, on Shield ASP, you know, we've seen this trend over, you know, over the past few quarters. We've really focused on the Medicare population and reimbursable tests. And I think, you know, we've done a really great job there. But there is, we are seeing a lot of demand for it from the under 65s. And so I think, you know, our assumption going into 2026 is that that demand will continue to grow, and that sort of mix of commercial versus Medicare is just going to increase. So, that's really what, you know, the fundamentals of how we see the ASP moving. We still, you know, we'll maintain the ADLT rate at $1,495.

Speaker #6: Yeah, on Shield ASP, we've seen this trend over the past few quarters. We've really focused on the Medicare population and reimbursable tests. And I think we've done a really great job there.

Speaker #6: But there is. We are seeing a lot of demand from the under-65s, and so I think our assumption going into '26 is that that demand will continue to grow.

Speaker #6: And that sort of mix of commercial versus Medicare is just going to increase. So that's really what the fundamentals of how we see the ASP moving.

Speaker #6: We still will maintain the ADLT rate at 14.95. That's now going to be in place for 26 and 27. And we're seeing great reimbursement from Medicare Advantage payers.

Mike Bell: You know, that's now going to be in place for 2026 and 2027. And we're seeing great reimbursement from Medicare Advantage payers, saying that's been leading to some out-of-period through as well. And our ASP for Medicare Advantage is getting stronger and stronger. But yeah, it's, it's just really gonna be, it's a mixed impact between Medicare and and non-Medicare. And on the international side, if the question was focused on Shield, you know, we've seen small contribution from Abu Dhabi in 2025. I think, you know, we expect, again, the international contribution to be relatively small in 2026. And really, the driver of the vast majority of the volume and the volume growth is gonna come from the US in 2026.

Speaker #6: Saying that's been leading to some out-of-period trips as well. And our ASP for Medicare Advantage is getting stronger and stronger. But yeah, it's just really going to be a mixed impact between Medicare and non-Medicare.

Speaker #6: And on the international side, if the question was focused on Shield, we've seen a small contribution from Abu Dhabi in '25. I think we expect, again, the international contribution to be relatively small in '26.

Speaker #6: And really, the driver of the vast majority of the volume and the volume growth is going to come from the US in 26.

Speaker #8: Thank you.

AmirAli Talasaz: Thank you.

Operator: The next question comes from the line of Daniel Markowitz with Evercore ISI. You may proceed.

Speaker #2: The next question comes from the line of Daniel Markovitz with Evercore ISI. You may proceed.

Speaker #8: Hey, thanks for taking my question. I wanted to ask about Reveal Ultra. It sounds like that's an area where there's a lot of excitement internally.

Daniel Markowitz: Hey, thanks for taking my question. I wanted to ask on Reveal Ultra. It sounds like that's an area where there's a lot of excitement internally. Can you talk a bit about what will be differentiated about the offering, how you see the tumor-informed competitive landscape evolving, and when we can expect to see some data or a more substantial update on that asset? Thanks.

Speaker #8: Can you talk a bit about what will be differentiated about the offering? How you see the tumor-informed competitive landscape evolving? And when we can expect to see some data or a more substantial update on that asset?

Speaker #8: Thanks.

Speaker #4: Yeah. Excited about reveal ultra. Making good progress there. We're on track for launching it this year. And it's something where we believe that the true clinical sensitivity of that test will be best in class.

Helmy Eltoukhy: Yeah, we're excited about Reveal Ultra. You know, making good progress there. We're on track for launching it this year, and it's something where we believe that that the true clinical sensitivity of that test will be best in class. I think there's a lot of, I would say, contrived messaging in this space in terms of different bars that people are using. But we believe that this will, I think, redefine sensitivity in the tumor-informed space. There are other features of the test. It's gonna do more than I think other tumor-informed offerings. We always have a special sauce at Guardant with all our tests in terms of when we launch them, and so I think I would just say stay tuned as we share more details later this year about that test.

Speaker #4: I think there's a lot of, I would say, contrived messaging in this space in terms of different bars that people are using, but we believe that this will, I think, redefine sensitivity in the tumor-informed space.

Speaker #4: There are other features of the test. It's going to do more than I think other tumor-informed offerings. We always have a special sauce at Guardant with all our tests in terms of when we launch them.

Speaker #2: The next question comes from the line of Andrew Brackman with William Blair. You may proceed.

Speaker #9: Hey, guys. Good afternoon. Thanks for taking the question. AmirAli, you sort of talked about the recent MFed legislation and sort of the longer-term impact there.

Andrew Brackmann: Hey, guys. Good afternoon. Thanks for taking the question. AmirAli, you, you sort of talked about the recent AMCAD legislation and sort of the longer-term impact there. Can you maybe just sort of broaden out that commentary, talk to us sort of about the importance there for Shield in particular? And as you sort of think about the necessary steps for Guardant to sort of take advantage of that, can you just remind us on sort of the data generation and sort of path to FDA approval here? Thanks.

Speaker #9: Can you maybe just sort of broaden out that commentary, talk to us sort of about the importance there for Shield in particular? And as you sort of think about the necessary steps for Guardant to sort of take advantage of that, can you just remind us on sort of the data generation and sort of path to FDA approval here?

Speaker #9: Thanks.

AmirAli Talasaz: Yeah. So, as I'm talking about this AMCAD bill that just passed. So, we are—as I mentioned in the prepared remarks, we are encouraged to see the passage of the legislation. It's moving the whole field forward, but it's not gonna be a meaningful driver of our business based on the business plan that we have in near term. But again, it's good for the field. You know, maybe as we go through midterm and talking about more than triannual testing with Shield, maybe there would be opportunities enabled with this AMCAD bill for us. But again, in near term, we don't look at it as a meaningful driver of our business.

Speaker #10: Yeah, so as you were talking about this MFed deal that just passed—so we are, as I mentioned in the prepared remarks, we are encouraged to see the passage of the legislation.

Speaker #10: It's moving the whole field forward. But it's not going to be a meaningful driver of our business based on the business plan that we have in the near term.

Speaker #10: But again, it's good for the field, maybe as we go through midterm, and talking about more than tri-annual testing, which Shield, maybe there would be opportunities enabled with this MFed deal for us.

Speaker #10: But again, in the near term, we don't look at it as a meaningful driver of our business.

Speaker #11: Hey, guys. Thank you. Hey, guys. Thank you for taking my question. A follow-up to Andrew's question. AmirAli, what has the opt-in rate for MFed Shield been so far?

Mike Bell: Hey, guys. Thank you. Hey, guys. Thank you for taking my question. A follow-up to Andrew's question, AmirAli, what has the opt-in rate for AMCAD Shield been so far? And if you were to accumulate significant data by year-end, would you be able to submit something to the FDA for AMCAD approval? I know it doesn't matter to the core story, but just trying to figure out, if, as we think about upside.

Speaker #11: And if you were to accumulate significant data by year-end, would you be able to submit something to the FDA for MFed approval? I know it doesn't matter to the core story, but just trying to figure out if as we think about upside.

Speaker #9: Yeah, thanks for this important question. When we are thinking about the data that now we are generating with this MCD offering for Shield, when the physician and patients are opting in, on one side, we are really encouraged by the enthusiasm that we are seeing on the provider side.

AmirAli Talasaz: Yeah. Thanks for this important question. You know, when we are thinking about the data that now we are generating with this MCD offering for Shield, when the physician patients are opted in, on one side, we are really encouraged by the enthusiasm that we are seeing on the provider side, and participation by patients who opt in to release their medical record to us. On the other side, on the data side, I think in, hopefully in near future, we would be the company that has access to the widest, broadest clinical data in terms of clinical utility of MCD testing in US patient population. So we are seeing good adoption rate. I don't want to get to the, you know, the exact number of it. It's trending up, but so far so good.

Speaker #9: And participation by patient to opt in to release their medical record to us. On the other side, on the data side, I think in hopefully near future, we would be the company that has access to the widest, broadest clinical data in terms of clinical utility of MCD testing in US patient population.

Speaker #9: So, we are seeing good adoption rate. I don't want to get to the exact number of it. It's trending up, but so far so good.

Speaker #9: So far so good. And we are very excited with it.

AmirAli Talasaz: So far so good, and we are very excited with it.

Operator: The next question comes from the line of Michael Reiskin with Bank of America. You may proceed.

Speaker #8: Hey, guys. Thank you for taking the question. This is Aaron on from Mike. Can you talk a little bit more about the puts and takes of the Shield guide?

[Analyst] (Bank of America): Hey, guys. Thank you for taking the question. This is Aaron on from Mike. Can you talk a little bit more about the puts and takes of the Shield guide? Obviously, Q4 saw the 14,000 in sequential volume growth. But, you know, should we think about, thinking about that as more of an anomaly and just kind of thinking about how much conservatism is embedded within the guide? And I guess the second part of that is, you know, thinking about Quest and Path, PathGroup, those look like upsides to the guidance. And so how should we be thinking about the timing of those impacts or those tailwinds as we head through the year? Thank you.

Speaker #8: You're obviously for it. You saw the 14,000 and sequential volume growth. But should we think about that as more of an anomaly, and just kind of thinking about how much conservatism is embedded within the guide?

Speaker #8: And I guess the second part of that is thinking about quest and path group. Those look like upsides to the guidance. And so how should we be thinking about the timing of those impacts or those tailwinds as we head through the year?

Speaker #8: Thank you.

Speaker #10: Yeah, sure. Obviously, we are very excited with this guide. 87,000 volume going to the midpoint of 217,000, and a very huge revenue growth and contribution.

AmirAli Talasaz: Yeah, sure. Look, obviously, we are very excited with this guide of like 87,000 volume going to midpoint of 217,000 and a very huge revenue growth and contribution. You know, on the other side, when we are thinking about the guide, you know, we are again just in the still very early inning of this launch. This is just the second year of launch, and we want to be thoughtful with our guidance. You know, we typically don't want to get too excited and get ahead of our skis just based on one quarter performance. But the trends are very positive. We are again very excited of how 2026 is going to shape out for us. In the prepared remarks, we talked about, you know, some of the Q1 seasonality in PCP offices.

Speaker #10: On the other side, when we are thinking about the guide, we are again just in the still very early inning of this launch. This is just the second year of launch.

Speaker #10: And we wanted to be thoughtful with our guidance. We typically don't want to get too excited and get ahead of our skis just based on one quarter performance.

Speaker #10: But the trends are very positive. We are again very excited about how 2026 is going to shape out for us. In the prepared remarks, we talked about some of the Q1 seasonality in PCP offices.

Speaker #10: It's kind of normal for us. But again, in terms of year-over-year growth for us, I think we are very excited with the guide that we put out there.

AmirAli Talasaz: It's kind of normal for us, but again, in terms of year-over-year growth for us, I think we are very excited with the guide that we put out there, and there are some upsides. We'll see, like, you know, we are very optimistic about the ACS guideline, and we believe it should be in near term. It's not part of our guide right now till they update their guideline. Quest, PathGroup, very minor contribution. We are counting on some benefit of the EMR connectivity enabled through this Quest and PathGroup integration, but we are not counting any kind of contribution in terms of the volume contribution of the co-promotion and volume that comes from Quest salespeople. We are going to monitor it.

Speaker #10: And there are some upsides, we'll see. We are very optimistic about the ACS guideline, and we believe it should be in soon. It's not part of our guide right now until they update their guideline.

Speaker #10: Quest, path group, very minor contribution. We are counting on some benefit of the EMR connectivity enabled through this quest and path group integration. But we are not counting any kind of contribution in terms of the volume contribution of the Quest salespeople.

Speaker #10: We are going to monitor it. It should be positive, but since we don't know exactly how positive it will be, we want to monitor for the first few months after the launch and see how it goes.

AmirAli Talasaz: It should be positive, but since we don't know exactly how positive it would be, we want to monitor for the first few months of the launch and see how it goes, and then if appropriate, we would adjust our guidance accordingly. But we just want to be thoughtful about that matter as well.

Speaker #10: And then if appropriate, we would adjust our guidance accordingly. But we just wanted to be thoughtful about that matter as well.

Operator: The next question comes from the line of Mark Massaro with BTIG. You may proceed.

Speaker #2: The next question comes from the line of Mark Massero with BTIG. You may proceed.

Speaker #9: Hey, guys. Thank you for the questions. I wanted to also ask about Shield. So for AmirAli, one of the success stories of one of the drivers of the success of Cologuard was their direct-to-consumer TV launch.

Mark Massaro: Hey, guys. Thank you for the questions. I wanted to also ask about Shield. So primarily, you know, one of the success stories of one of the drivers of the success of Cologuard was their direct-to-consumer TV launch. How are you thinking about spending in 2026? Is it more select digital, or do you anticipate some spend on TV? And then I also wanted to ask about Quest. There is access for the, I believe, the Quest salespeople to promote Shield. I just want to double-check that these reps are incentivized, and then can you just maybe give us a sense for where the Shield test might sit in their bag relative to the other products they're selling?

Speaker #9: How are you thinking about spending in 2026? Is it more select digital, or do you anticipate some spend on TV? And then I also wanted to ask about Quest.

Speaker #9: There is access for the, I believe, the Quest salespeople to promote Shield. I just want to double-check that these reps are incentivized, and then can you maybe give us a sense for where the Shield test might sit in their bag relative to the other products they're selling?

Speaker #10: Yeah, so some BTC pilot has actually happened for us in 2025 in select markets. And in 2026, we are excited that hopefully consumers and even physicians would see even more of that.

AmirAli Talasaz: Yes. So some DTC pilot has actually happened for us in 2025 in select markets, and in 2026, we are excited that hopefully, consumers and even physicians will see even more of that. So we have some active campaigns that they are about to get finalized, and we are excited to put it out there and see what the impact would be. So we are very excited about it. The rest, stay tuned after we launch it in very near future. In terms of Quest, yeah, actually, the salespeople are incentivized. It's part of their commission plan.

Speaker #10: So we have some active campaigns that they are about to get finalized, and we are excited to put it out there and see what the impact would be.

Speaker #10: So we are very excited about it. The rest stay tuned after we launch it in very near future. In terms of Quest, yeah, actually, the salespeople are incentivized.

Speaker #10: It's part of their commission plan. And what we do know is actually it was very important and interesting for the Quest management team to get access to Shield as a very differentiated brand that gives them opportunity to talk about something new and something exciting with the accounts.

AmirAli Talasaz: And what we do know is actually, it was very important and interesting for the Quest management team to get access to Shield as a very differentiated brand that gives them opportunity to talk about something new and something exciting, exciting with the accounts. So again, we are going to monitor how the launch goes with Quest in terms of co-promotion part of it. It should be, again, positive, but we'll see how positive it would be.

Speaker #10: So again, we are going to monitor how the launch goes with Quest in terms of co-promotion part of it. It should be again positive, but we'll see how positive it would be.

Operator: The next question comes from the line of Kyle Mixon with Canaccord. You may proceed.

Speaker #8: Hey, guys. Thanks for the questions. On the meta site acquisition, interesting to see that. Most of the consideration is tied to future commercial performance and the regulatory approvals too of the technology.

[Analyst] (Bank of America): Hey, guys. Thanks for the questions. On the MetaCyte acquisition, interesting to see that most of the consideration is tied to future, like, commercial performance and the regulatory approval, too, of the technology. So, first one, wondering what the path is to non-cancer launches. And then second, it seems like they use mass spec. How does that factor into your NGS-heavy platform? Thanks.

Speaker #8: So, first one, wondering what the path to the non-cancer launch is. And then, second, seems like the mass spec—how does that factor into your NGS-heavy platform?

Speaker #8: Thanks.

Speaker #10: Yeah, so we are very actually excited about this acquisition to bring a very high-quality world expert on some specific complementary technologies to our smart platform.

AmirAli Talasaz: Yeah. So we are very, actually excited about this acquisition, to bring the, you know, very high-quality world expert on some specific complementary technologies to our SMART Platform. So we are very excited to go to work and see what we can do. It's a small technology talking again, so let us make more progress, and we will talk about it at the right time.

Speaker #10: So, we are very excited to go to work and see what we can do. It's a small technology, talking again. So let us make more progress, and we will talk about it at the right time.

Speaker #2: The next question comes from the line of Casey Woodring with JPMorgan. You may proceed.

Operator: The next question comes from the line of Casey Woodring with JPMorgan. You may proceed.

Casey Woodring: Great. Thank you for taking my question. Just a couple more on Shield, maybe. So you mentioned that the guide is back half weighted. What does that guide imply for Shield in Q1? You know, I think that comment would imply a sizable step down, sequentially.

Speaker #11: Great, thank you for taking my question. Just a couple more on Shield, maybe. So, you mentioned that the guide is back half-weighted. What does that guide imply for Shield and Q1?

Speaker #11: I think that that comment would imply a sizable step down sequentially. And then, I guess on the ACS commentary you made—if that hits in the first half of 2026—can you help us think about the upside to volumes in the back half of the year, and what that could look like?

Luke Sergott: ... and then, you know, I guess on the ACS commentary you made, if that hits in the first half of 2026, can you help us think about the upside to volumes in the back half of the year and what that could look like? Thank you.

Speaker #11: Thank you.

Speaker #10: Yeah. Maybe I serve with the ACS part. Let us actually see when it would happen. It should be in the near future. But I think when you think about our dozen states that they have state-level mandates, that even younger patient populations should get access to the test.

AmirAli Talasaz: Yeah. Maybe I start with the ACS part. You know, let us actually see when it would happen. It should be in near future, but, you know, I think when you think about our, about 12 states, that they have state-level mandates, that even younger patient populations should get access to the test. And the whole screening market is maybe about 40%, you know, this, you know, 65 year and above, and, more are, in fact, on the younger patient side. That could be an interesting upside and growth driver for us once we start really going much deeper on the commercial testing within those states. But let's first see actually when they update their guideline, and we go from there.

Speaker #10: And the whole screening market is maybe about 40% this 65-year and above. And more are, in fact, on the younger patient side. That could be an interesting upside and growth driver for us once we start really going much deeper on the commercial testing within those states.

Speaker #10: But let's first see actually when they update their guideline. And we go from there. In terms of Q1, yeah, that's true that there is some Q1 seasonality in PCP offices, which in terms of screening and so forth.

AmirAli Talasaz: In terms of Q1, you know, yeah, that's true that, you know, there's some Q1 seasonality in PCP offices, which, you know, the, in terms of screening and so forth. But our team has done a very good job, you know, to reschedule appointments that have been kind of impacted or the events that have been impacted. And we are on track to screen more patients in Q1 than in any other previous quarters post-launch. So let's see how the rest of the quarter goes, but, and we'll talk about it in our next earnings call.

Speaker #10: But our team has done a very good job to reschedule appointments that have been kind of impacted or the events that have been impacted.

Speaker #10: And we are on track to screen more patients in Q1 than in any other previous quarters. Post-launch. So let's see how the rest of the quarter goes.

Speaker #10: But and we will talk about it in our next earning call.

Speaker #2: The next question comes from the line of Dan Arias with Steeple. You may proceed.

Operator: The next question comes from the line of Dan Arias with Stifel. You may proceed.

Speaker #12: Good afternoon. This is Paul Allen for Dan. Thanks for the questions. I guess I just want to follow up on Subu's question about kind of regulatory strategy for multi-cancer Shield.

Dan Arias: Good afternoon. This is Paul on for Dan. Thanks for the question. I guess I just want to follow up on Subbu's question about kind of regulatory strategy for multi-cancer Shield. One of your competitors had some data out this afternoon with, you know, not meeting a primary endpoint with a very, very large MCD trial in terms of looking for stage shift. And then, you know, one other piece was this week in the New England Journal, there was some FDA willingness to, you know, be a little more flexible on what evidence generation might look like. I'm just wondering if, you know, any of these developments kind of influence what you would look to do for your evidence generation strategy and for your regulatory strategy with Shield MCD?

Speaker #12: One of your competitors had some data out this afternoon with not meeting a primary endpoint with a very, very large MSED trial. In terms of looking for stage shift, and then one other piece was this week in the New England Journal there was some FDA willingness to be a little more flexible on what evidence generation might look like.

Speaker #12: I'm just wondering if any of these developments kind of influence what you would look to do for your evidence generation strategy and for your regulatory strategy with Shield MCD.

Speaker #10: Actually, this news just came out. So I don't know all the details of it. We've been on this call with you guys. But I think when I think about it, really, what is important in the field of multi-cancer detection is the performance of detecting early stages.

AmirAli Talasaz: Actually, this news just, you know, came out, so, I don't know all the details of it, you know, beyond this call with you guys. But I think, when I think about it, really, what is important in the field of multi-cancer detection is the performance of detecting early stages. And we believe with the technology that we have for Shield, the performance of early stage detection, you know, as it's shown in CRC, could be very interesting, and that could have a meaningful impact. On the other side, I think it really highlights what we are doing to capture all the clinical evidence, medical record of the patients who are going through MCD testing in US, and really establish the utility of this MCD testing at very large scale.

Speaker #10: And we believe with the technology that we have, for Shield, the performance of early-stage detection, as it's shown in CRC, could be very interesting.

Speaker #10: And that could have a meaningful impact. On the other side, I think it really highlights what we are doing to capture all the clinical evidence, medical records of the patients who are going through MCD testing in the U.S.

Speaker #10: And really establish the utility of this MCD testing at very large scale. We are going to benefit from this commercial scale of Shield, and we can put that evidence together in a very optics-friendly and in a very quick way.

AmirAli Talasaz: We are going to benefit from this commercial scale of Shield, and we can put that, you know, evidence together in a very, you know, OpEx friendly and in a very quick way. So I think it's kind of we are getting more bullish with the pathway that we went after screening business and what we are doing with our MCED offering.

Speaker #10: So, I think it’s kind of—we are getting more bullish with the pathway that we went after in the screening business and what we are doing with our MSED offering.

Speaker #2: The next question comes from the line of Luke Surgod with Barclays. You may proceed.

Operator: The next question comes from the line of Luke Sergott with Barclays. You may proceed.

Speaker #12: Great. Thanks for the question. Excuse me again. So on the Shield demand and after you guys have had this for a year and a half now, but this is like the full first full year launch.

Luke Sergott: Great. Thanks for the question, squeezing me in. So on the Shield demand, and after you guys have had this, you know, for a year and a half now, but this is like the first full year launch. It's been great. You're going to trend even further for next year. Can you kind of give us a sense of where the demand is coming from? Like, how much of this is from, like, care gap closure versus winning share from colonoscopy or FIT or Cologuard or any of the other tests?

Speaker #12: It's been great. You're going to trend even further for next year. Can you kind of give us a sense of where the demand is coming from?

Speaker #12: How much of this is from the care gap closure versus winning share from colonoscopy or FIT or Cologuard or any of the other tests?

AmirAli Talasaz: Yes, so the demand is coming from PCP, PCP physician in terms of patient type. Still, we are really focused on unscreened patient population. I think some of the latest data that I've seen, about still 90% of the patients who are getting screened by Shield have not been screened before, at least during the last 5 years, when we got access to their medical record and claims. So, really, our messaging is working, and we are increasing the rate of overall screening. Care gap and, you know, those kind of opportunities still is ahead of us. We need to get, you know. We need to qualify for quality scores, and Shield still is not. Once we get to the HEDIS, that would be a huge additional growth driver for us.

Speaker #10: Yeah. So the demand is coming from PCP physician in terms of patient type. Still, we are really focused on unscreened patient population. I think some of the latest data that I've seen about still 90% of the patients who are getting screened by Shield have not been screened before, at least during the last five years.

Speaker #10: When we got access to their medical record and claims. So really, our messaging is working, and we are increasing the rate of overall screening.

Speaker #10: Care gap and those kind of opportunities still is ahead of us. We need to get into we need to qualify for quality scores. And Shield still is not.

Speaker #10: Once we get to the heaters, that would be a huge additional growth driver for us. So, Care Gap program is not part of our growth right now.

AmirAli Talasaz: Care gap program is not part of our growth right now.

Speaker #2: The next question comes from the line of Jack Meehan with Nephron Research. May proceed.

Operator: The next question comes from the line of Jack Meehan with Nephron Research. You may proceed.

Speaker #12: Thanks. Good afternoon. Appreciate all the color on the screening investments you're making. Was wondering if you could share color on the oncology side—specifically, just a mark-to-market, how large the sales force is there now, and planned investments.

Jack Meehan: Thanks. Good afternoon. Appreciate all the color on the screening investments you're making. Was wondering if you could share color on the oncology side, specifically just to mark to market, how large the sales force is there now, and planned investments. And then second, you've talked about the NovaSeq X transition. When in the year is that taking place, and any way you can quantify level of savings you expect? Thank you.

Speaker #12: And then second, you've talked about the NovaSeek X transition. When in the year did that take place? And is there any way you can quantify the level of savings you expect?

Speaker #12: Thank you.

Helmy Eltoukhy: ... Yes, I think, yeah, obviously, as Mike said, we reached cash flow positivity on the oncology side last year, and we obviously will be generating cash this year. We're in a really good spot in terms of where we are with oncology. We've been essentially reinvesting in the business as a matter of course, as we see opportunities for growth on the sales side, as we see the revenue per rep sort of grow. We saw two around a healthy number in terms of as a matter of course expansion of the team. So we're in a healthy spot, and we'll continue to sort of invest where we see return on investment in terms of potential volume growth. In terms of the NovaSeq transition, maybe I'll let Mike take that one.

Speaker #13: Yeah, so I think, yeah, obviously, as Mike said, we reached cash flow positivity on the oncology side last year, and obviously we'll be generating cash this year.

Speaker #13: We're in a really good spot in terms of where we are with oncology. We've been essentially reinvesting in the business as a matter of course, as we see opportunities for growth on the sales side, as we see a revenue per rep sort of grow.

Speaker #13: We saw around a healthy number in terms of a matter of course expansion of the team. So we're in a healthy spot, and we'll continue to sort of invest where we see return on investment in terms of potential volume growth.

Speaker #13: In terms of the NovaSeek transition, maybe I'll let Mike take that one.

Speaker #14: Yeah. I mean, first of all, we've successfully transitioned to Reveilo. It's a NovaSeek X just over a year ago. And as well as workflow efficiencies, we saw a nice reduction in the cost per test of Reveilo.

Mike Bell: Yeah. You know, we. I mean, first of all, we've successfully transitioned the Reveal, obviously, NovaSeq X, just over a year ago. As well as workflow efficiencies, you know, we saw a nice reduction in the cost per test of Reveal. And with Guardant360, we started that transition. It'll take time to fully be implemented. Probably around about the, you know, middle of the year, I would expect all the Guardant360 liquid tests to be on NovaSeq X. And yeah, you know, we expect to see a nice improvement in our cost per test. I think, you know, just to quantify it a little bit, you know, our gross margin currently for Guardant360 is in the high 60s%.

Speaker #14: And with Guardant 360, we started that transition. It'll take time to fully be implemented. Probably around about the middle of the year, I would expect all Guardant 360 liquid tests to be on NovaSeek X.

Speaker #14: And yeah, we expect to see a nice improvement in our cost per test. I think just putting to quantify it a little bit, our gross margin currently for Guardant 360 is in the high 60s.

Mike Bell: And probably what, you know, once we've gone through the full move to NovaSeq X, and things are working properly, you know, I expect to see, you know, maybe 200 basis point improvement and sort of pushing that Guardant360 gross margins into the low 70% level. So, yeah, no, we're feeling very positive about the switch, and it's gonna have a nice impact on our P&L.

Speaker #14: And probably once we've gone through the full move to NovaSeek X and things are working properly, they expect to see maybe 200 basis points improvement.

Speaker #14: And it's sort of pushing that Guardant 360 gross margin into the low 70 percent level. So, yeah, no, we're feeling very positive about the switch, and it's going to have a nice impact on our P&L.

Speaker #15: Operator, one more question, please. Thank you.

Zarak Khurshid: Operator, one more question, please. Thank you.

Speaker #2: Perfect. Our last question comes from the line of Bill Bonello with Craig Hallam. You may proceed.

Operator: Perfect. Our last question comes from the line of Bill Bonello with Craig-Hallum. You may proceed.

Speaker #16: Hey, guys. Thanks a lot for hanging on and taking another question. So this one, I guess, is probably for Helmy. I think that, if I understand it right, FDA approval would open the door to physicians being able to order both tissue and blood from Guardant concurrently.

Bill Bonello: Hey, guys. Thanks a lot for hanging on and taking another question. So, this one, I guess, is probably for Helmy. I think the... If I understand it right, that the, you know, FDA approval would open the door to physicians being able to order both tissue and blood from Guardant concurrently. I'm just curious, you know, what your sense of is for the appetite for using both tests up front, and then also touch on maybe any reimbursement challenges that you might anticipate if that, it becomes more common.

Speaker #16: I'm just curious, what your sense of is for the appetite for using both tests upfront and then also touch on maybe any reimbursement challenges that you might anticipate if that becomes more common?

Speaker #13: Yeah. As you know, guidelines, I think, are increasingly recommending that for patients upfront, especially in lung cancer and breast cancer, which are some of our two largest indications for 360.

Helmy Eltoukhy: Yeah, as you know, guidelines, I think, are increasingly recommending that for patients up front, especially in lung cancer and breast cancer, which are some of our two largest indications for Guardant360. Yeah, one of the challenges is, you know, the way that LDT is reimbursed. You know, it really is not possible to order them concurrently. So that's obviously been a little bit of a headwind that sort of will become a tailwind once we get FDA approval for Guardant360. So we do see that as a potential driver. Obviously, you know, we wanna make sure it's done in the cases where it's, you know, there's clinical utility for the patients and value for treatment selection.

Speaker #13: And yeah, one of the challenges is the way that LDT is reimbursed. It really is not possible to order them concurrently. And so that's obviously been a little bit of a headwind that sort of will become a tailwind once we get FDA approval for Guardant360.

Speaker #13: So we do see that as a potential driver. Obviously, we want to make sure it's done in the cases where there's clinical utility for the patients and value for treatment selection.

Speaker #13: But we're very confident that, I think, will be, I think, an important catalyst for our tissue business going forward.

Helmy Eltoukhy: But we're very confident that, I think, will be an important catalyst for our tissue business going forward.

Speaker #2: Due to the interest of time, that was our last question. That will conclude today's call. Thank you for your participation and enjoy the rest of your day.
