 means that creditors of Boston Scientific’s other subsidiaries (including trade creditors) and holders of their preferred stock, if any, will have priority with respect to the assets of such subsidiaries over Boston Scientific’s claims (and therefor the claims of Boston Scientific’s creditors, including holders of the notes).

The notes and guarantees will be effectively junior to any secured indebtedness that AMS Europe or Boston Scientific may incur in the future.

The notes and guarantees will be unsecured. As of December 31, 2024, neither AMS Europe nor Boston Scientific had any secured debt outstanding. Holders of secured debt that AMS Europe or Boston Scientific may issue in the future may foreclose on the assets securing such debt, reducing the cash flow from the foreclosed property available for payment of unsecured debt, including the notes and guarantees. Holders of secured debt also would have priority over unsecured creditors in the event of AMS Europe’s or Boston Scientific’s bankruptcy, liquidation or similar proceeding to the extent of the collateral securing

such secured debt. As a result, the notes and guarantees will be effectively junior to any secured debt that AMS Europe or Boston Scientific may issue in the future.

#### AMS Europe may issue additional notes.
Under the terms of the indenture that will govern each series of the notes offered hereby, AMS Europe may from time to time without notice to, or the consent of, the holders of any series of notes, create and issue additional notes of a new or existing series, which notes, if of an existing series, will be equal in rank to the notes of that series in all material respects so that, subject to certain tax considerations, the new notes may be consolidated and form a single series with such notes and have the same terms as to the status, voting rights, redemption or otherwise as such notes.

Redemption may adversely affect your return on the notes.

The notes are redeemable at AMS Europe’s option, and therefore AMS Europe may choose to redeem the notes at times when prevailing interest rates and/or credit spreads are relatively low. As a result, you may not be able to reinvest the proceeds you receive from the redemption in a comparable security at an effective interest rate as high as the interest rate on your notes being redeemed.

We may not be able to repurchase all of the notes upon a Change of Control Repurchase Event.

As described under the heading “Description of the Notes - Repurchase at the Option of Holders Upon Change of Control Repurchase Event
