Boston Scientific trims outlook, flags Q4 sales decline

Nate Gregory
Published Oct 28, 2026
Share:
Summary:
  • Boston Scientific cut its sales guidance and said fourth quarter net sales could fall up to 3% year over year.
  • It now sees full year adjusted EPS at $3.16 to $3.18 versus analysts' $3.23, and projects fourth quarter adjusted EPS of $0.77 to $0.79.
  • By 9:32 a.m. Wednesday in New York, the stock was off 9%, and it was already down 53% for the year as of Tuesday's close.

What happened

Boston Scientific said it lowered its sales outlook and expects a fourth quarter decline in net sales. In August, the medical device maker was hit by a cyberattack that disrupted operations worldwide, and soon after warned it would miss full year targets for net sales and adjusted earnings.

Guidance and commentary

The company now anticipates adjusted earnings for the full year in a range of $3.16 to $3.18, below the $3.23 consensus, and fourth quarter adjusted EPS between $0.77 and $0.79. It also expects fourth quarter net sales to be down as much as 3% from a year earlier.

On the earnings call, Chief Financial Officer Jon Monson said, "2026 has been a challenging year for us," noting that after several years of growth in parts of its cardiovascular portfolio, "we've seen that cycle turn." He added that Boston Scientific has rolled out a new operating model that should make its forecasts more accurate going forward.

Market surprises remind investors that staying informed and adapting tools preserves long-term gains. We're hosting our first ever investor livestream on 11/17 to show you how to use ChatGPT and Claude to invest like a pro, hosted by Briefs Finance CEO Jaspreet Singh. Save your seat.

What it means for investors

The lowered guidance coincided with a sharp move in the shares, which were 9% lower at 9:32 a.m. Wednesday and had already fallen 53% year to date through Tuesday's close. The near term watch items are whether fourth quarter sales land within the guided decline and if the new operating model improves forecasting accuracy as intended.

Smart use of new investing tools can help steady decision making through uncertainty. On 11/17, our CEO Jaspreet Singh goes live for our first ever investor livestream on how to use ChatGPT and Claude to invest like a pro. Register to join him.

Are We in a Recession? 5 Threats to the Economy and Where the Money Is Moving
By Andre Savage
  • The S&P 500 is up about 13% this year, but without AI it's in a bear market, with nearly 40% of its companies down more than 20% for four months or longer.
  • Jackson, Briefs Finance's head of investing research, sees five threats: rising interest rates, sticky inflation, an economy propped up by AI, a struggling UK, and high oil prices.
  • The opportunities he's watching mostly sit outside the dollar: rising economies like Brazil and Indonesia, US-backed emerging market bonds paying 7% to 9%, and the shifts that fear creates.

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
By Jackson Moreland
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • The most common mistake is treating the letter as an instruction. An A tells you a stock scores well for one goal, not that you should buy today.
  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.

What Type of Investor Am I? The Three Investor Archetypes, Explained
By Milena Thomas
  • Briefs sorts its stock grades and monthly reports by three investor goals: growth, income, and wealth preservation. Pick yours and you know which report and which grade to read first.
  • Growth investors want stocks that beat the S&P 500. Income investors want to get paid in cash. Wealth preservation investors want stocks that hold up when the market drops.
  • The same stock can score an A- for one goal and a D- for another, so picking your goal comes before picking any stock.

Is This Stock a Good Buy? How to Use the Briefs Score to Tell If a Stock Fits the Way You Invest
By Nate Gregory
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • One stock can score very differently for each. Nvidia showed an A- for growth and a D- for income, because it grows fast and pays almost no dividend.
  • Seven sub scores under each grade show what earned the letter, so you can see exactly where a stock is strong or weak for your goal.

How to Tell an Asset From a Liability: The One Question to Ask Before You Buy Anything
By Briefs Finance
  • The typical American household earned more in 2025 than in any year on record, yet only 30% of Americans say they could pay a surprise $1,000 bill from savings, so the problem isn't income but what the income gets spent on.
  • An asset puts money in your pocket and a liability takes money out, and the wealthy buy assets first, then let the assets pay for the fun stuff.
  • Before you buy anything, ask one question: does this put money in my pocket, or take money out of my pocket? Then you need a plan for the money you keep.

How to Build Your First $2,000 Emergency Fund and Wipe Out Every Debt Over 10%
By Briefs Finance
  • Your first money goal isn't investing, it's $2,000 in its own account named Do Not Touch, built by moving 10% of every paycheck into it automatically.
  • More than a third of American adults couldn't cover a $400 surprise bill with cash or savings, according to the Federal Reserve, and that's how one bad day turns into years of credit card payments.
  • Once the $2,000 is there, attack every debt charging more than 10% interest, highest rate first, because you can't out-invest a 22% credit card so paying it off is the investment.
