Danielle Antalffy's questions to BOSTON SCIENTIFIC (BSX) leadership

Question · Q3 2025

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. He also highlighted the generational opportunity with the implantable platform refresh and the disruptive potential of conduction system pacing technology.
