Investment Thesis

▲ Bull case

Boston Scientific's FARAPULSE pulsed field ablation platform is demonstrating transformative clinical outcomes that are accelerating adoption beyond initial projections, particularly in the persistent atrial fibrillation population, which represents a significant unmet medical need and a major growth opportunity. The AVANT GUARD trial demonstrated statistical superiority of FARAPULSE over anti-arrhythmic drugs with significantly higher primary effectiveness, and real-world data shows redo rates after de novo persistent AF ablation have fallen into single-digit levels, indicating durable efficacy. This clinical validation, combined with the integration of OPAL HDx mapping and the upcoming FARAPOINT PFA catheter launch, positions the company to expand its addressable market in EP substantially, with global PFA penetration projected to grow from 50% at year-end 2025 to approximately 80% by 2028, driven by technological advancements and expanding clinical evidence that support broader patient access and reimbursement.
The concomitant WATCHMAN and FARAPULSE procedure (FARAWATCH) is emerging as a powerful growth catalyst that is underappreciated by the market, with management indicating that 25% of U.S. WATCHMAN procedures are already being performed concomitantly exiting 2025, and the potential for this to double by 2028. This trend is reinforced by strong clinical evidence from the OPTION-A trial and real-world data from the ALIGN-AF study, which confirms the safety and efficacy of combined procedures without compromising acute success. The FARAWATCH approach not only increases procedural volume and revenue per case but also strengthens customer loyalty and creates a defensible ecosystem that leverages Boston Scientific's leadership in both WATCHMAN (over 600,000 cumulative patients) and FARAPULSE, driving sustained mid-teens growth in WATCHMAN and accelerating EP market share gains through bundled solutions that address both stroke prevention and rhythm control in a single setting.
Boston Scientific's strategic investments in high-growth adjacencies, particularly the agreement to acquire Nalu Medical for peripheral nerve stimulation and the $1.5 billion investment in MiRus for access to the nickel-free SIEGEL TAVR system, are creating multi-year growth platforms that are not yet fully reflected in current guidance. The Nalu acquisition expands the neuromodulation portfolio into a large, underserved pain market with solid Medicare reimbursement and improving commercial payer coverage, complementing the recently acquired Relievant SI business and strengthening the company's position in peripheral nerve pain—a segment with minimal competition. Simultaneously, the MiRus investment provides an exclusive option to acquire a differentiated TAVR technology built on a proprietary rhenium alloy with potential advantages in delivery (8 French sheath, 50% smaller than competitors) and hemodynamics, positioning Boston Scientific to re-enter the TAVR market with a next-generation offering that could capture share from established players as the SIEGEL valve advances through the STAR pivotal trial targeting up to 1,025 patients. These moves align with the company's capital allocation priority of tuck-in M&A in high-growth areas and are expected to contribute meaningfully to long-range organic growth targets of 10%+ annually from 2026-2028.

▼ Bear case

Boston Scientific's Watchman device is facing a structural shift in procedure patterns that is undermining its historical growth trajectory, as declining uptake of standalone procedures is being driven by physicians increasingly combining Watchman with other heart treatments during a single visit, rather than performing it as a standalone procedure. CEO Michael Mahoney explicitly warned at the Bernstein conference that this trend is leading to flat dollar growth expectations for Watchman from Q1 to Q2 2026 and likely into Q3, directly contradicting prior assumptions of sustained high-growth contribution from the franchise. This behavioral change among electrophysiologists and interventional cardiologists reduces procedural volume and revenue per case, as concomitant procedures—while growing—do not fully offset the decline in standalone usage, and the company is now questioning the long-term growth rate of Watchman, which had been a cornerstone of its cardiovascular growth story and a key driver behind its 20% LRP market CAGR assumption.
The electrophysiology business is experiencing faster-than-expected market share losses due to intensified competition from Medtronic, Johnson & Johnson, and Abbott, which is eroding the mixed benefit that management had anticipated at the start of the year, as CFO Jonathan Monson acknowledged. Despite strong underlying market growth in PFA and ablation therapies, Boston Scientific's inability to maintain or grow its share in this high-growth segment threatens to cap the upside from its EP franchise, particularly as the business anniverves against exceptional prior-year performance and faces increasing competitive pressure in both the U.S. and international markets. This share erosion is particularly concerning given that EP sales grew 63% in Q3 2025, setting a high bar for continued outperformance, and any deceleration in growth—or worse, absolute decline—would significantly impact overall company performance, especially since EP has been a primary driver of both revenue and margin expansion through favorable product mix.
Urology segment performance remains persistently below expectations, with Axonics specifically cited as underperforming due to post-commercial disruption challenges, and management's outlook for improvement is contingent on operational enhancements that have yet to materialize, creating uncertainty around a key international growth lever. Although Urology showed 27% operational growth in Q3 2025, this was largely driven by international business and Stone Management, with organic growth of only 5%, and Axonics—the company's investment in sacral neuromodulation—continues to lag, requiring focused efforts on strengthening the commercial team, patient activation, and globalization opportunities. The segment's reliance on international contributions and the lack of clear near-term catalysts for Axonics recovery raise concerns about its ability to contribute meaningfully to long-term growth, especially as management has reiterated that Urology growth will improve throughout 2026 only if commercial execution improves, which remains unproven and introduces execution risk into a segment that was expected to be a more reliable contributor to the company's diversified growth profile.
