Management Comments

• "Our Cardiovascular segment delivers 16% growth operationally and organic in fourth quarter and 22% operationally and 21% organic on a full-year basis."
• "In January, we announced the agreement to acquire Penumbra, which is expected to close in 2026. Penumbra offers a highly differentiated portfolio that operates in high-growth segments where Boston Scientific lacks offerings, including mechanical thrombectomy and neurovascular. The deal is both strategically and financially attractive to Boston Scientific and delivers significant value to patients and customers globally."
• "As of December 31, 2025, we had cash on hand of $1.965 billion, and our gross debt leverage ratio was 1.9 times."
• "Following the announcement of our agreement to acquire Penumbra, all three major rating agencies affirmed our single A minus equivalent credit rating. Additionally, Fitch Ratings upgraded our outlook from stable to positive."
• "Our capital allocation priority remains strategic tuck-in M&A, followed by share repurchases."
• "If were doing our Investor Day today, wed get the same numbers, 10% plus 2026 to 2028, 150 bps of margin improvement, a strong double-digit EPS growth even within that."
• "Our whole key to our business is being in fast growth markets, which weve demonstrated. We anticipate in that time horizon the WAMGR gets closer to 9%. Penumbra actually could slightly even improve that once that closes by a small margin, but slightly improve it. And excluding Penumbra, were very comfortable with those LRP goals as weve stated."
