    Yuko Oku's questions to Tempus AI (TEM) leadership

    Yuko Oku's questions to Tempus AI (TEM) leadership • Q2 2025

    Question

    Yuko Oku from Morgan Stanley inquired about the expected cadence of Average Selling Price (ASP) for the remainder of the year, considering the migration of XT volumes to CDx and the ramp-up of the unreimbursed XM test. She also asked if Tempus plans to add features like RNA and epigenomic markers to its tissue tests.

    Answer

    CFO Jim Rogers explained that while the migration to higher-value CDx tests continues toward the 40% year-end goal, a mix shift to lower-reimbursement assays like XM will temper the uplift. He anticipates small, incremental ASP gains over the year rather than a significant step-up. CEO Eric Lefkofsky added that Tempus has performed whole transcriptome RNA sequencing from the beginning and has a comprehensive panel, suggesting future advancements are more likely on the DNA side, such as migrating to whole genome sequencing.

    Yuko Oku's questions to VERACYTE (VCYT) leadership • Q2 2025

    Question

    Yuko Oku of Morgan Stanley asked for early feedback on the digital pathology offering and its potential for broader commercialization. She also inquired about which cancer types beyond bladder cancer the company's unique whole-genome MRD platform might be best suited for.

    Answer

    CEO Marc Stapley described digital pathology as a nascent, complementary technology and reiterated the company's strategy to focus on robust, collaborator-led research via the GRID platform before any clinical launch.

    Question

    Yuko Oku from Morgan Stanley, on behalf of Tejas Savant, asked about the extent of market development needed to drive adoption for Decipher in the new metastatic prostate cancer setting. She also sought to clarify if the Bethesda V LCD would drive new Afirma volume or primarily impact ASP for existing tests.

    Answer

    CEO Marc Stapley stated that since the customer base is largely the same urologists, market development will be an extension of current efforts and not require a significant change in spending. CFO Rebecca Chambers and Stapley explained the Bethesda V opportunity is a modest tailwind for both volume and ASP, as it's a small portion of the total population and the Medicare cohort is smaller than the commercial one.

    Yuko Oku's questions to Personalis (PSNL) leadership

    Yuko Oku's questions to Personalis (PSNL) leadership • Q2 2025

    Question

    Edmund Tu, on behalf of Yuko Oku from Morgan Stanley, asked for an updated estimate on the impact of policy headwinds on the biopharma business and inquired about NextPersonal's differentiation following a competitor's recent coverage determination, as well as the balance between near-term margin pressure from investments and future revenue.

    Answer

    CFO & COO Aaron Tachibana confirmed the biopharma guidance was revised down due to project delays in the translational research business. CEO Christopher Hall positioned a competitor's recent reimbursement as a positive sign for the field, expressing confidence that Personalis's data also meets the bar for coverage. Tachibana addressed the investment balance by stating the company is prioritizing volume growth ahead of reimbursement to maximize the revenue run-rate once coverage is secured, noting the current margin guidance of 22-24% already accounts for these unreimbursed test costs.

    Yuko Oku's questions to Personalis (PSNL) leadership • Q3 2024

    Question

    Yuko Oku inquired about the rationale for increasing NeXT Personal sample volumes with Tempus ahead of reimbursement and asked about the expected gross margin cadence into 2025.

    Answer

    CEO Christopher Hall explained that the expansion with Tempus is a strategic move to train a large sales force, positioning the company for explosive growth once reimbursement is secured. CFO Aaron Tachibana added that Tempus's capital injection supports this pre-reimbursement ramp. Regarding margins, Tachibana projected significant headwinds of 15-18 percentage points in 2025 due to unreimbursed test costs, which could cause margins to decline from 2024 levels, with formal guidance to be provided later.

    Yuko Oku's questions to Adaptive Biotechnologies (ADPT) leadership • Q2 2025

    Question

    Yuko Oku from Morgan Stanley inquired about the importance of the CHMP positive opinion for pharma customers and its potential to increase focus on ex-U.S. opportunities. She also asked for physician feedback on the MIDUS trial data and whether it was driving clonoSEQ volume.

    Answer

She confirmed it helps prioritize a European expansion in the 'not distant future.' Regarding the MIDUS trial, she said physician feedback has been positive, especially in the community, as it opens up dialogue with patients about transplant decisions, though it's too early to point to a direct volume inflection.

    Question

    Yuko Oku, on for Tejas Savant at Morgan Stanley, asked if EMR integrations are generating cost savings and whether pharma partner cost-cutting is shifting contracts towards more back-end loaded milestone payments.

    Answer

    Executive Susan Bobulsky confirmed operational efficiencies from EMRs are being realized, citing a 90% drop in order callbacks at one large account, but these savings are not yet in the 2025 guidance. CEO Chad Robins added that for pharma contracts, Adaptive is actively moving toward more front-loaded, recurring fee-for-service models to reduce revenue lumpiness, not the other way around.

    Yuko Oku's questions to Guardant Health (GH) leadership • Q2 2025

    Question

    Yuko Oku from Morgan Stanley asked about the potential market split between comprehensive panels like Guardant360 and simpler hotspot tests for monitoring ESR1 mutations following the SERENO-six trial, and also inquired about the broader impact of Medicaid cuts on cancer testing.

    Answer

    Chairman & Co-CEO Helmy Eltoukhy positioned the SERENO-six application as a 'beachhead' for a new adaptive disease management paradigm. As the enrolling assay and future companion diagnostic for camisestrant, he believes Guardant360 is positioned to capture the majority of this new opportunity. VP of Investor Relations Zarak Khurshid and CFO Michael Bell later clarified that Medicaid represents a minimal portion of overall volume and revenue, so any cuts would not have a material impact.

    Question

    Yuko Oku of Morgan Stanley inquired about the specifics of the assay and surface chemistry changes, the technical issues they address, and their impact on the platform's initial specifications, cost structure, and pricing.

    Answer

    Parag Mallick, Co-Founder and Chief Scientist, explained the changes aim to enhance the specific binding of affinity reagents and reduce non-specific binding. CEO Sujal Patel added that this approach de-risks development and increases the yield of functional probes, which should improve proteome coverage. Patel also confirmed the changes should not negatively impact costs and that the target pricing of approximately $1 million for an initial instrument bundle remains appropriate given the platform's differentiated data quality.

    Yuko Oku's questions to Nautilus Biotechnology (NAUT) leadership • Q3 2024

    Question

    Yuko Oku of Morgan Stanley inquired about the higher-than-expected fallout rate for affinity probe candidates and the progress of proteoform capabilities relative to the broad-scale discovery platform.

    Answer

    Parag Mallick, Co-Founder and Chief Scientist, explained that the high fallout rate is due to an extensive characterization process that tests kinetics, binding diversity, and manufacturability. He noted that while a wide distribution in probe performance was expected, the diversity of epitopes the probes can target is a significant positive. Mallick also clarified that while the broad-scale and proteoform platforms share a common core, they have matured at different rates. Customer interest has driven the company to prioritize proving out the proteoform opportunity in the first half of 2025 through collaborations, which will also help harden the platform for the broad-scale early access launch planned for the second half of 2025.
