Boston Scientific Climbs 40.5% in a Year: What's Driving the Stock?
Read MoreHide Full Article
Key Takeaways
BSX stock rose 40.5% over the past year, beating industry and the benchmark's performance.
WATCHMAN and FARAPULSE devices, plus MedSurg gains, powered BSX's double-digit organic revenue growth.
Acquisitions and emerging market expansion added to BSX's strong Q1 sales and growth outlook.
Boston Scientific (BSX - Free Report) has delivered an impressive return over the past year, with shares rallying 40.5%. The performance outpaced the industry’s 14.3% gain and the S&P 500 composite’s 12.5% rise.
Carrying a Zacks Rank #2 (Buy) at present, the renowned medical device maker is gaining from the continued success of its WATCHMAN device, which supports the fast momentum in the structural heart programs. Consistent market share gains in the MedSurg segment are highly impressive. As part of its long-term growth strategy, BSX continues to expand its international presence, including in emerging markets and pursue acquisitions.
Marlborough, MA-based Boston Scientific develops, manufactures and markets medical devices used in a broad range of interventional medical specialties. The company has advanced the practice of less-invasive medicine in diagnosing and treating a wide range of diseases and medical conditions, offering alternatives to surgery and other medical procedures that are typically traumatic to the body. Its research and development efforts focus on breakthrough technologies aimed at expanding current markets or entering adjacent ones.
Catalysts Behind BSX’s Growth
The rally in the share price can be linked to the company’s strong performance of the WATCHMAN left atrial appendage closure device. In particular, the next-generation WATCHMAN FLX and FLX Pro are strongly capturing the global market. In the first quarter of 2025, WATCHMAN sales grew 24% year over year, supported by an increase in the concomitant procedures enabled by the new DRG, effective since October. Boston Scientific reported that more than half of the U.S. EP implanting customers are now performing at least one concomitant procedure — a trend expected to continue throughout the rest of 2025.

The company’s MedSurg segment continues to capture market share, led by strong performance across several areas. The Endoscopy business sees robust growth in endoluminal surgery and single-use imaging franchises, along with sustained momentum in the AXIOS platform, where Boston Scientific is reinvesting to expand indications. Within Urology, the Stone management and prosthetic urology franchises are growing well, backed by key launches with the TENACIO pump for the AMS 700 and continued success with the expanding LithoVue portfolio. Within Neuromodulation, the pain and brain businesses are gaining traction.
Notably, Electrophysiology growth accelerated in the first quarter of 2025, growing 145% organically, fueled by rapid and sustained adoption of the transformative FARAPULSE PFA System. FARAPULSE remained at the forefront of AFib market transformation in 2024, surpassing $1 billion in global revenues and treating over 200,000 patients.
Meanwhile, Boston Scientific’s recent acquisitions, including Bolt Medical, Cortex and Axonics, have expanded its portfolio with numerous high-potential products, many of which are still in development. Sales from closed acquisitions contributed 400 basis points in the first quarter, resulting in 18.2% organic revenue growth for the company. Boston Scientific is also presently in the process of closing the acquisitions of SoniVie and Intera Oncology.
Besides, the company is actively expanding its footprint in the emerging markets (excluding countries like the United States, Western and Central Europe, Japan, Australia, New Zealand and Canada), which hold strong growth potential based on their economic conditions, healthcare sectors and global capabilities. In the first quarter of 2025, despite geopolitical weaknesses, emerging markets registered sturdy growth, primarily banking on continued broad-based momentum across the company’s business and investment in this region. Emerging markets’ net sales grew nearly 9.8% on an operational basis, year over year.
