Dan Arias's questions to METTLER TOLEDO INTERNATIONAL INC/ (MTD) leadership

Question · Q3 2025

Dan Arias asked about the extent to which onshoring demand could impact Mettler-Toledo's business in 2026 versus 2027 and beyond, particularly for products that might be adopted earlier in the process. He also sought a comparison of expectations for China's lab/biopharma side versus the industrial side for next year, considering macro headwinds.

Answer

Patrick Kaltenbach, Chief Executive Officer, stated Mettler-Toledo is well-positioned to benefit from re- and onshoring activities in pharma, semiconductor, and other sectors, with about 50% of sales in production and QA/QC.

Dan Arias's questions to Tempus AI (TEM) leadership

Question · Q3 2025

Dan Arias inquired about Tempus AI's R&D investments in MRD, specifically asking about data to look out for next year, given the anticipated influx of high-sensitivity assays into the market over the next 12-18 months.

Answer

CEO Eric Lefkofsky confirmed Tempus AI's continuous release of publications, posters, and presentations. Regarding MRD, he highlighted ongoing studies for their tumor-naive assay in non-small cell lung cancer and a re-evaluation of CRC work, with interesting data expected next year for both. He anticipates hitting 'super powerful' metrics on the tumor-naive side, allowing them to compete effectively with tumor-informed assays due to internal enhancements by their large technical team. For tumor-informed MRD, he deferred to Personalis for their roadmap.

Question · Q2 2025

Dan Arias from Stifel Financial Corp. asked for expectations on data business growth for the second half of the year, noting that the growth rate had ticked down sequentially and faces tougher year-over-year comparisons in Q3 and Q4.

Dan Arias's questions to WATERS CORP /DE/ (WAT) leadership

Question · Q3 2025

Dan Arias followed up on the biosimilar opportunity, asking about the extent to which pill count increases, rather than just dollar sales, underpin the incrementally larger opportunity each year, and the margin impact of new products coming to market over the next 12 months.

Answer

CEO Udit Batra explained that increased biosimilar availability, driven by analytical characterization replacing clinical studies, would lower prices, increase access, and significantly boost penetration and volume (pill count) for advanced therapies globally, improving patient health. CFO Amol Chaubal stated that new products, a healthy mix of bioanalytical characterization, bioseparations (chemistry), and Empower (software), are meaningfully accretive to gross margin. He added that while new instruments aren't fully value-engineered initially, products like Alliance iS and TQ Absolute are now due for value engineering, which will contribute to margin accretion.

Question · Q3 2025

Dan Arias followed up on the biosimilar opportunity, asking about the extent to which pill count increases underpin the projected revenue growth over the next few years, and how this translates into an incrementally larger volume opportunity for Waters. He also inquired about the potential margin impact of new products coming to market over the next 12 months.

Answer

President and CEO Udit Batra explained that increased biosimilar availability, driven by reduced clinical study requirements and reliance on bioanalytical characterization, would lower prices, increase access, and significantly boost penetration and volume growth for advanced therapies, benefiting patient health globally. CFO Amol Chaubal noted that new products are a healthy mix of bioanalytical characterization, bioseparations (Chemistry), and Empower (software), which are meaningfully accretive to gross margin, offsetting any initial lower margins from instrument-related new products that are not yet fully value-engineered.

Question · Q2 2025

Dan Arias requested clarification on the updated guidance, asking if the 1% headwind was solely due to a specific gene therapy platform or if it reflected a broader adjustment for the entire new modalities sector.

Question · Q2 2025

Dan Arias asked for an update on the risk of the business being impacted by China's Volume-Based Procurement (VBP) policies. He also sought to confirm the expected revenue contribution from the Genomics England contract in the second half.

Answer

CEO Prahlad Singh reiterated that the current headwind is from DRG policy, not VBP, though the government's overall goal is cost reduction.

Dan Arias's questions to THERMO FISHER SCIENTIFIC (TMO) leadership

Question · Q3 2025

Dan Arias inquired about the demand from small and emerging biotech companies, asking if spending is loosening up given the improved BTK index. He also asked about China's pricing initiatives, specifically on the research and industrial side, and whether these dynamics introduce additional risk or are expected to remain stable into year-end and early 2026.

Answer

Marc Casper (Chairman, President and CEO) noted a strong quarter for biotech, observing nice momentum in clinical research and early activities in pharma services. He found the M&A transactions by large pharma acquiring biotech encouraging, as they help the ecosystem and drive reinvestment. Regarding China, Mr. Casper stated it's a smaller percentage of total company revenue. He noted academic and government benefited from stimulus but faced pressure from economic challenges, while pharma and biotech grew modestly. Overall, China declined mid-single digits, an improvement from Q2 due to the absence of April trade activity secession. He expects full-year China to be down mid to high single digits, with less government pricing impact in industrial/pharma/biotech compared to diagnostics.

CFO Stephen Williamson noted that while the Analytical Instruments business is impacted by muted academic and China markets, it has a positive book-to-bill and could see upside if the tariff situation remains better than the company's conservative guidance assumes.

Dan Arias from Stifel Financial Corp. questioned why the company guided towards the low end of its system placement range despite encouraging commentary on pharma build-outs, and also asked about the stability and growth outlook for the consumables business.

Answer
