// Full episode scriptWelcome to Beta Finch, your AI-powered earnings breakdown! I'm Alex.
And I'm Jordan. Today we're diving into Boston Scientific's fourth quarter and full year 2025 results - and wow, what a year it's been for this medical device giant.
Before we jump in, I need to mention that this podcast is AI-generated content for educational and entertainment purposes only. Nothing we discuss should be considered investment advice. Always do your own research and consult a qualified financial advisor before making any investment decisions.
Absolutely. So Alex, Boston Scientific just wrapped up what CEO Mike Mahoney called an "outstanding" year. Let's start with the headline numbers - they're pretty impressive.
They really are. For the full year, Boston Scientific hit over $20 billion in sales - that's 19% operational growth and nearly 16% organic growth. They actually exceeded their guidance of around 15.5%. And on the bottom line? Adjusted earnings per share of $3.06, up 22% year-over-year.
That's their third consecutive year of 20%+ EPS growth, which is remarkable consistency in this industry. But what I found interesting was the fourth quarter specifically - 13% organic growth, which hit the high end of their guidance range. The question is, what's driving all this growth?
Two words: EP and WATCHMAN. Their electrophysiology business grew 35% in Q4 and a staggering 73% for the full year. That's largely driven by their FARAPULSE technology - basically a next-generation treatment for atrial fibrillation that uses pulsed field ablation instead of traditional methods.
And WATCHMAN, their left atrial appendage closure device, grew 29% in the quarter. Mike Mahoney mentioned they've now treated more than 25,000 patients with what they call "concomitant procedures" - essentially doing WATCHMAN and EP procedures together, which is more efficient for hospitals.
But here's where it gets really interesting - and where some investors got a bit nervous during the earnings call. There were questions about whether growth is slowing, especially in the U.S. EP market. Some analysts were expecting even higher numbers.
Right, and Mahoney pushed back on this pretty hard. He said competitors are claiming the EP market grew 25% in Q4, but Boston Scientific thinks it was more like 18-20%. And even at that growth rate, they're significantly outpacing competitors - some major players only grew 6.5% and 12.5% respectively.
That's a crucial point for investors. Market share dynamics are shifting as competitors launch their own PFA products, but Boston Scientific believes they'll maintain clear market leadership. Mahoney said by year-end 2026, their PFA share might equal all other competitors combined, but they'll still be the leader.
And looking ahead, they're guiding for some pretty solid numbers in 2026. Organic revenue growth of 10-11% for the full year, though Q1 will be softer at 8.5-10% due to some one-time headwinds and tough comparisons.
Those headwinds include discontinuing a product called ACURATE and a temporary withdrawal of certain sizes of their AXIOS device due to manufacturing issues. But they expect both situations to resolve by mid-year.
Let's talk about what could be a game-changer - the CHAMPION trial results. This is a major clinical study comparing their WATCHMAN device to blood thinners for stroke prevention. Dr. Ken Stein, their Chief Medical Officer, said results will be presented at the American College of Cardiology conference.
If positive, this could be huge. Currently, WATCHMAN is indicated for about 5 million patients globally who can't tolerate blood thinners. But if CHAMPION shows WATCHMAN is as effective as blood thinners with better bleeding outcomes, that addressable market could jump to 20 million patients.
That would essentially position WATCHMAN as a first-line therapy instead of just for patients who can't take drugs. The financial implications could be enormous.
Beyond the core growth drivers, Boston Scientific is also making some strategic moves. They announced an agreement to acquire Penumbra, a neurovascular company, which would get them into high-growth markets like mechanical thrombectomy for stroke treatment.
And they're not ignoring their other businesses. Their Interventional Oncology unit hit nearly $1 billion in sales with 12% organic growth. Their coronary business grew 20% in Q4, driven by products like their Agent drug-coated balloon.
One thing that stood out in the Q&A was how diversified their growth is becoming. Mahoney said six of their eight business units grew faster than their respective markets. While EP and WATCHMAN grab the headlines, they're seeing strength across neuromodulation, endoscopy, and interventional cardiology.
The margin story is solid too. They expanded adjusted operating margins by 100 basis points to 28% in 2025, and they're guiding for another 50-75 basis points of expansion in 2026. That shows they're not just growing the top line - they're getting more profitable as they scale.
Free cash flow was particularly strong - $3.66 billion for 2025, representing 80% conversion. They're guiding for about $4.2 billion in 2026. That gives them plenty of firepower for acquisitions and investments in R&D.
Looking at the longer-term picture, Boston Scientific reaffirmed their 2026-2028 targets: 10%+ organic revenue growth, 150 basis points of operating margin expansion, and double-digit EPS growth. Those are pretty ambitious goals in the current environment.
The key question for investors is sustainability. Can they maintain this growth as competitors catch up in EP and as some of their markets mature? Mahoney seems confident, pointing to geographic expansion opportunities, especially in China and Japan, plus a robust pipeline of new products.
Geographic diversification is interesting. The U.S. grew 17% in Q4, but Asia-Pacific grew 15%, and they're still early innings in markets like China for many of their technologies.
One risk worth watching is the increasing competition in EP. Boston Scientific built their dominant position early with FARAPULSE, but as more competitors enter, maintaining share will get tougher. The good news is they have a broader ecosystem approach with mapping systems and other complementary technologies.
Bottom line for investors: Boston Scientific delivered a strong 2025 and is guiding for continued solid growth in 2026. The CHAMPION trial results could be a significant catalyst, and their diversified portfolio provides some protection against any single product headwinds.
The valuation will be key to watch. With this kind of growth, the stock isn't cheap, so execution will be critical. But if they can deliver on their long-term targets while expanding into new markets through acquisitions like Penumbra, there's still a compelling growth story here.
