Question · Q4 2025

Danielle Antalffy from UBS asked for a high-level assessment of Enovis's portfolio, focusing on product breadth, competitive positioning, and areas needing improved execution or product gap filling, inquiring about organic versus inorganic strategies. She also questioned the sustainability of the PNR portfolio's mid to high single-digit growth for 50% of its products and the potential for further portfolio shaping.

Answer

Damien McDonald (CEO) emphasized opportunities in commercial execution and a rich new product introduction pipeline, adopting a 'singles and doubles' approach. He reiterated debt reduction as the primary capital allocation priority, limiting inorganic moves to 'generational opportunities.' For PNR, he discussed continued portfolio shaping, geographic expansion, and new product launches like Manafuse, with Ben Berry (CFO) adding that PNR growth is crucial for achieving consistent high single-digit overall growth.

Danielle Antalffy's questions to PROCEPT BioRobotics (PRCT) leadership

Question · Q4 2025

Danielle Antalffy inquired about the extent of the market development component, asking how much of a 'heavy lift' market education is and its role in the procedure volume bridge and long-term plan. She also asked about the potential for Aquablation to be performed in an ASC setting as part of the long-term plan and for an update on the company's model for covering cases.

Answer

President and CEO Larry Wood stated that historically, the company focused on system placement and training, with minimal marketing or awareness efforts. He highlighted the need for fundamental work to articulate Aquablation's value proposition to patients (e.g., on WebMD, social media, comparisons), describing it as a continuous build rather than a quick fix. He confirmed that the ASC setting is part of the long-term plan, though not a near-term focus. Mr. Wood also mentioned that an update on how the case coverage model will evolve over time to improve efficiency will be provided at tomorrow's Investor Day.

Answer

Larry Wood, Chief Executive Officer, noted that historically, the company focused on system placement and procedure execution, but 'none of that work was done' for marketing, awareness, or value proposition to patients. He emphasized that basic fundamental work, such as improving online presence and making the value proposition case, is a 'continual build' but can be done quickly to make a difference, with a significant focus at tomorrow's Investor Day. Mr. Wood confirmed that ASCs will 'certainly' be part of the long-term plan, though not a near-term focus. He also mentioned updates on evolving models for case coverage to improve efficiency.

Question · Q4 2025

Danielle Antalffy's questions to Inspire Medical Systems (INSP) leadership

Question · Q4 2025

Danielle Antalffy expressed concern about managing a growing patient funnel with a potential physician bottleneck due to reimbursement issues, asking what happens to patients and if some centers might be willing to take on more patients.

Answer

Tim Herbert, Chairman and CEO, emphasized that Inspire V is a 'rock-solid product' with strong clinical evidence, driving the company's commitment to patients. He acknowledged variability in professional fee reductions with the -52 modifier but believes Inspire's experience with 10,000 Inspire V procedures in 2025 provides a strong basis to work with payers to minimize reductions. Herbert noted that facility reimbursement actually increased by $1,000 from last year, making it strong at facilities. He stated that Inspire can direct more patients to salary-based surgeons or centers where surgeons are partial owners, as they are less impacted by professional fee changes, while diligently working with private practices.

Question · Q4 2025

Answer

Yair Malca, InMode CFO, stated the guidance is conservative. Moshe Mizrahy, InMode CEO, explained that new laser products (Pico, Erbium YAG, CO2), some acquired from external companies, have inherently lower gross margins and are subject to U.S. tariffs, impacting overall margins. Mr. Mizrahy noted that while lasers are 'bread and butter' in medical aesthetics and complement InMode's RF technology, the laser market is saturated, leading to lower prices and margins.

Danielle Antalffy from UBS asked about the cadence of growth in Boston Scientific's Cardiac Rhythm Management (CRM) business, which has been growing below market, especially with a competitor in a new product cycle. She sought insights into how upcoming new product launches, such as Denali and EMPOWER, are expected to impact the business's growth trajectory.

Answer

Chairman and CEO Mike Mahoney noted satisfaction with LUX ICM performance and highlighted multi-year investments in the Denali platform, a complete refresh of core pacemaker/defibrillator products launching in late H2 2026 and throughout the LRP. He also expressed enthusiasm for EMPOWER, their entry into the leadless pacemaker market, which will complement SICD. Mahoney stated that while unit growth has been at market, dollar growth has been below due to gaps in higher ASP leadless products. He is confident the CRM business will strengthen and contribute more significantly over the LRP. Chief Medical Officer Dr. Ken Stein added that EMPOWER is important for leadless and SICD growth, and the Elutia acquisition provides an important adjunctive technology.
