Boston Scientific Shares Slide After Management Lowers Growth Outlook

Company trims organic growth targets and flags segment-specific pressures while reaffirming margin and EPS goals

By Sofia Navarro BSX

Boston Scientific Corp. shares fell more than 6% on Wednesday after executives reduced the companyull-year organic growth outlook and provided weaker second-quarter guidance during a presentation at Bernstein. Management said it still expects margin improvement and double-digit EPS growth, but cited headwinds in standalone WATCHMAN procedures, Electrophysiology competitive dynamics, and softness in the urology franchise as drivers of the revision.

Key Points

  • Boston Scientific trimmed full-year organic growth guidance to 6.5% - 8.0% and set Q2 guidance at 5% - 7%.
  • Guidance cut driven by weaker standalone WATCHMAN procedures, reduced Electrophysiology outlook amid competitor launches, and softness in the urology segment.
  • Company expects margin improvement and double-digit EPS growth despite the lowered growth forecast; plans to update long-range projections after Q3 results.

Boston Scientific Corp. (NYSE:BSX) experienced a sharp market reaction Wednesday after senior management lowered its organic growth forecast for the year while speaking at a Bernstein event. The stock declined by over 6% following the guidance reduction.

Management adjusted the company's full-year organic growth guidance to a range of 6.5% to 8.0%. For the second quarter, the company set guidance between 5% and 7%. Company leadership said it is comfortable operating within those updated ranges and reiterated an expectation of margin improvement together with double-digit growth in earnings per share despite the trimmed outlook.

The guidance revision stems from several business-specific challenges. Executives pointed to a slowdown in standalone WATCHMAN procedures, weaker-than-expected performance in the urology segment and reduced Electrophysiology guidance tied to competitor product launches.

On WATCHMAN, Boston Scientific continues to hold an estimated 91% market share, yet management reported a decline in standalone procedures. The slowdown is partly attributed to competitive pressures and workflow issues, and the company expects WATCHMAN dollar growth to be roughly flat from the first quarter into the second quarter and likely into the third quarter as well.

In Electrophysiology, where Boston Scientific ranks as the second-largest player globally, management said the company expects to keep PFA market-share leadership. That said, they acknowledged the company could lose some share as competitors introduce new products, which contributed to the lowered Electrophysiology guidance.

The urology business was described as facing headwinds from niche and price competitors within its core stone portfolio. Management also noted commercial disruption tied to Axonics in the urology channel. To address these challenges, the company has added roughly 100 clinical and sales representatives focused on improving performance in the Axonics urology business.

Looking ahead, Boston Scientific plans to update its three-year long-range plan - including projections for fiscal 2027 and 2028 - following its third-quarter earnings call. The company also signaled continued investment in innovation, allocating more than 9% of revenue to internal organic research and development and maintaining what it described as the largest venture fund in MedTech.


Market reaction - Shares fell more than 6% on the day of the announcement as investors absorbed the lowered near-term growth outlook despite management's pledge to drive margins and EPS higher over time.

Risks

  • Continued decline in standalone WATCHMAN procedures could pressure near-term revenue growth and affect cardiac device market dynamics - impacting medical device and healthcare equipment sectors.
  • Competitive product launches in Electrophysiology may erode market share, creating uncertainty for revenue and margin trajectories in electrophysiology-related markets.
  • Persistent commercial disruption in the urology business, including competitive pricing and niche competitors in the stone portfolio, could limit recovery and weigh on medtech and urology supply chains.
