Dan Brennan's questions to GeneDx Holdings (WGS) leadership

Question · Q3 2025

Dan Brennan of TD Cowen asked about the NICU's contribution to Q3 2025 volumes and Q4 guidance, the drivers behind the better-than-expected Q3 performance, and the outlook for OpEx spending, particularly regarding the general pediatrician market.

Answer

Katherine Stueland, CEO and President, noted significant NICU growth and progress on Epic Aura integrations. Kevin Feeley, CFO, detailed that Q3 strength came from core outpatient markets, with strong conversion to exome/genome and pNeuro account activation. He outlined OpEx investments in a dedicated pediatrician sales team and R&D, expecting sequential OpEx growth to drive mid-2026 volume, while reaffirming profitability.

Question · Q3 2025

Dan Brennan asked for an update on GeneDx's NICU performance in Q3, including its contribution to the implicit Q4 volume guide and early feedback. He also sought details on the drivers of Q3's better-than-expected performance, specifically regarding same-store sales growth, new indications, and new doctors, and how these factors inform the Q4 guidance. Finally, Brennan requested clarification on the OpEx outlook, particularly the expectation for pediatrician volume growth by mid-2026 and the impact of the pediatrician call point.

Answer

Katherine Stueland, CEO and President, highlighted the NICU as a significant opportunity, noting fewer than 5% of babies receive genetic testing and confirming meaningful growth in same-store sales. Kevin Feeley, CFO, added that NICU volumes are growing nicely, tracking towards an incremental 2,000 units in H2 2025, mostly in Q4. He attributed Q3's strength to core outpatient markets, particularly expert geneticists and pediatric neurologists, with strong account activation. Feeley explained that OpEx investments, including building a dedicated general pediatrician sales team, are deliberate for long-term growth, expecting similar sequential OpEx growth from Q3 to Q4 while maintaining profitability.

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

Question · Q3 2025

Dan Brennan asked for further elaboration on the onshoring announcements, specifically how to quantify the incremental demand from CapEx, capacity, and drug volumes, distinguishing between greenfield and brownfield projects. He sought to understand the potential sizing and magnitude of this impact for Thermo Fisher, including equipment uptake in 2026.

Answer

Marc Casper (Chairman, President and CEO) clarified that onshoring generates incremental one-time demand for new equipment, initial stocking, and labs over the next few years, even if overall drug volumes remain constant. He highlighted Thermo Fisher's stronger current presence, particularly in bioproduction, Solventum filtration, and DynaSpin bioreactor technology, which positions them for a higher share in new facilities compared to existing ones. Mr. Casper noted that while he couldn't provide an aggregate number, it should be a tailwind for bioproduction, which is already performing exceptionally well with strong bookings. Stephen Williamson (SVP and CFO) addressed the EPS impact of tariffs, stating that Q3 saw an $0.11 favorable pickup from tariffs and related FX compared to prior guidance. For Q4, he expects tariff assumptions to hold, with no significant pickup, given the increased tariffs between the U.S. and Europe since the last guidance.

Dan Brennan's questions to DANAHER CORP /DE/ (DHR) leadership

Question · Q3 2025

Dan Brennan asked about the bioprocessing equipment side, specifically how Cytiva's built-up capacity and the trend of reshoring/onshoring might impact demand over the next few years, including potential benefits for capital demand and recurring revenue in late 2026/2027. He also inquired about the 2026 guide for the life science segment, particularly the assumption of flat growth, and whether this is a conservative estimate for instruments versus genomics.

Answer

Rainer Blair (President and CEO) explained that equipment demand is driven by manufacturing growth and regionalization of capacity (reshoring). He expects continued investment, starting with brownfield projects for quicker capacity, followed by larger greenfield investments over several years, potentially leading to an extended capital cycle. Policy changes and tariff/MFN discussions have been an overhang but are dissipating, providing more confidence. For life sciences, Matt McGrew (EVP and CFO) confirmed the flat growth assumption for 2026. Rainer Blair added that clinical/applied markets are solid, pharma R&D is modestly recovering, but academic/government demand (low single-digit exposure) is soft. He expects some headwinds from large customers in life science consumables to lap, leading to modest growth next year, but for planning, flat growth is prudent until order trends confirm upside.

Question · Q3 2025

Dan Brennan asked for a broader perspective on the bioprocessing equipment side, specifically how Cytiva's built-up capacity and the trend of reshoring might impact demand over the next few years, distinguishing between incremental demand and regional shifts, and potential benefits for Danaher in late 2026 into 2027. He also sought further details on the 2026 life science guide, which assumes flat growth, asking for a breakdown between instruments and genomics, and what would be needed to achieve even zero growth, questioning if this outlook is conservative.

Answer

Rainer Blair, President and CEO, explained that equipment demand is driven by manufacturing growth and regionalization of supply chains (reshoring). While policy discussions have delayed investments, confidence is growing as overhangs dissipate. He expects initial brownfield investments to quickly add capacity, followed by larger greenfield projects, potentially leading to an extended capital cycle, though this has not yet translated into orders. Regarding life sciences, Mr. Blair noted that clinical and applied markets remain solid, and pharma research spending shows modest recovery. The academic and government segments, which are a smaller exposure, are currently anchoring growth. He also mentioned that life science consumables are lapping headwinds from large customers. Matt McGrew, Executive Vice President and CFO, confirmed the flat growth assumption for life sciences in 2026, consistent with recent performance, but acknowledged potential upside if order trends improve.

Dan Brennan's questions to MDxHealth (MDXH) leadership

Question · Q1 2025

Dan Brennan (via an unknown analyst on the line) asked for more detail on the accelerated tissue growth, including doctor adoption rates for the combined portfolio, pricing opportunities for GPS, and the reasons for slower growth in liquid-based tests.

Answer

CEO Michael McGarrity explained that tissue growth is driven by both a 'push' from pathology partners and successful penetration within large urology practices, leading to 'sticky', compliant adoption without expanding the sales force. On pricing, he noted the focus is on both advancing ASPs and reducing COGS through scale and efficiency. Regarding liquid tests, McGarrity described the slower growth as a tactical decision to focus sales incentives on the higher-margin, higher-growth tissue-based portfolio, which is performing as planned.

Dan Brennan's questions to EXAGEN (XGN) leadership

Question · Q4 2024

Dan Brennan asked about commercial payer feedback on the new markers, the size of the RA market opportunity, the strategy for volume growth in 2025, and the outlook for operating expense leverage.

Answer

John Aballi stated that payer feedback is positive, with denials mostly related to out-of-network status, which they can appeal effectively. He sized the addressable market at ~2.5 million annual tests and expects volume growth to improve to high single-digits with an expansion of the sales force.
