AI snapshot
Six angles, distilled from the data.
BSX remains in a long-term recovery regime after trading well below its 52-week high of 109.5 and above its 52-week low of 42.2. The stock is still under its 200-day average, but the 50-day average has turned up sharply versus the longer trend, signaling a rebuilding base rather than a mature breakout.
Street sentiment stays constructive: the consensus is Buy, with 8 Buy and 3 Hold ratings and no Sells. The average target sits at 62.69, above the last close, though several firms trimmed targets in late July, pointing to cautious optimism rather than aggressive upside chasing.
Boston Scientific has a clean beat streak, going 8-for-8 on EPS with the latest quarter topping by 3.6%. Next-year EPS is still expected to rise to 3.4385 from a 2.47 TTM base, so shareholders should watch whether margin discipline and procedure growth keep supporting that step-up.
The pattern is net buying, led by meaningful discretionary purchases from the CEO and directors. Automatic vesting and tax-related transactions also appeared, but the discretionary buys outweigh them and signal confidence from senior leadership rather than routine compensation noise.
Profitability is solid, with a 69.2% gross margin, 22.9% operating margin, and 17.5% net margin. Growth is still healthy too, with revenue up 7.5% year over year and earnings up 15.1%, while free cash flow reached $5.41 billion in fiscal 2025.
BSX stands out as a premium medical-device name with strong margins and a 0.566 beta, which is lower-volatility than many healthcare equipment peers. The valuation still looks reasonable at 16.72 times earnings, especially against its growth profile and analyst target range.

Boston Scientific beat Q2 expectations, but cut 2026 guidance as WATCHMAN and U.S. EP slowed more sharply than expected.· July 29, 2026
- Q2 organic revenue grew 7% and adjusted EPS was $0.86, both above guidance.
- Management cut full-year 2026 organic revenue guidance to 5% to 6% and EPS to $3.28 to $3.32.
- WATCHMAN and U.S. electrophysiology were the main sources of the guidance reset; both are expected to stay pressured into 2027.
- A restructuring program aims to generate about $500 million in run-rate savings exiting 2029.
- Core businesses outside WATCHMAN and EP represent roughly 75% of revenue and are expected to grow about 6% in the second half.
Second-quarter 2026 consolidated revenue was $5.442 billion, up 7.5% reported and 7.0% operationally/organically versus Q2 2025, including a 50 basis point FX tailwind. Adjusted EPS was $0.86, up 15% year over year and above the $0.82 to $0.84 guidance range, helped by favorable discrete tax items. Adjusted gross margin was 70.3%, up 80 basis points year over year, and adjusted operating margin was 28.4%, up 70 basis points; GAAP operating margin was 21.6%. For 2026, the company now expects reported revenue growth of 5.5% to 6.5% and operational/organic growth of 5% to 6%, Q3 revenue growth of 3% to 5%, adjusted EPS of $3.28 to $3.32, full-year adjusted operating margin expansion of 0 to 25 basis points, a tax rate of about 11.5%, and free cash flow of about $3.8 billion. The company also said Q2 free cash flow was $1.290 billion and cash on hand was $539 million, with gross debt leverage at 2.0x.
Mike Mahoney described Q2 as solid, but said the company now sees the second half of 2026 as more pressured than expected. He pointed to unexpectedly sharp U.S. WATCHMAN slowdown tied to clinical evidence affecting referrals, and stronger-than-anticipated competitive share loss in U.S. EP. He emphasized that Boston Scientific remains confident in the long term, citing a pipeline of catalysts in 2027 and 2028, including new product launches, Penumbra, MiRus/TAVR optionality, and a restructuring program to support a return to stronger growth.
Jon Monson detailed the quarter and updated outlook with specific figures: $5.442 billion of revenue, 7.0% operational growth, $0.86 adjusted EPS, 70.3% adjusted gross margin, and 28.4% adjusted operating margin. He said the quarter included about a $75 million product liability charge and roughly $80 million of tariff refunds, and that adjusted tax rate was 10.4%. He also said full-year 2026 free cash flow should be about $3.8 billion, adjusted below-the-line expense about $485 million, adjusted tax rate about 11.5%, and weighted average shares about 1.475 billion, while the restructuring should deliver about $500 million in run-rate savings exiting 2029.
Analysts focused on whether the new guidance reflected conservatism or worsening trends, and management said the reset was based on actual second-half dynamics already visible in WATCHMAN and EP, not just prudence. On WATCHMAN, management said the slowdown stems from changed referral patterns after recent clinical data, higher comp pressure on concomitant procedures, and weak stand-alone growth; they added that they are not assuming improvement in 2027 until the market actually changes, though they will continue physician education, commercial investment, and direct-to-patient efforts. On EP, management said U.S. share has come down as PFA adoption accelerated faster than expected, and that improvement should come in late 2027 and 2028 with FARAWAVE Ultra, ICE, and later FARAFLEX.
Management said roughly 75% of the business is still expected to grow about 6% in the second half, and several areas including Interventional Cardiology, Neuromodulation, IO&E, and Vascular posted double-digit growth through the first half. The company also highlighted a meaningful pipeline of launches and adjacency opportunities for 2027-2028, plus a restructuring program intended to improve cost efficiency and support a return to stronger EPS growth later.
The company now expects WATCHMAN to be flat to low-single-digit for the full year, with a mid- to high-single-digit decline in the second half, and does not assume improvement in 2027. EP guidance was also cut, with management citing U.S. competitive share pressure and a market that has shifted faster than expected. Management also said 2027 will likely have limited EPS growth and margin pressure, including some dilution from Penumbra and lower mix from WATCHMAN and EP.

A “Sell” may be a pre-scheduled 10b5-1 plan sale rather than a discretionary decision — read insider selling with that in mind.

Boston Scientific (BSX): Growth Reset, Still a Buy
Boston Scientific posted solid Q2 2026 growth, but lowered full-year guidance as WATCHMAN and U.S. EP slowed. The stock looks more reasonable after the reset, with durable pipeline optionality and a Buy rating.

Boston Scientific's $9 million insider buy is a vote against the WATCHMAN panic
Three insiders bought $9.29 million of BSX shares in roughly two weeks, including a roughly $9 million purchase by CEO Michael Mahoney. That confidence signal lands alongside 19.9% revenue growth, 55.6% EPS growth and a valuation that already reflects a reset.

Medtech's selloff is a payer-mix warning, not a demand collapse
The setbacks at Intuitive Surgical and HCA expose real pressure in elective procedures, but the evidence points more to coverage and payer mix than a broad healthcare demand collapse. UnitedHealth's guidance increase and Intuitive's maintained procedure outlook show why investors should separate marginal-patient exposure from underlying utilization.
