Revolving Credit Agreement

On February 26, 2026, Boston Scientific Corporation (the “Company”) entered into a $3.000 billion revolving credit agreement (the “2026 Revolving Credit Agreement”) by and among the Company, as borrower, the several lenders party thereto, and Wells Fargo Bank, National Association, as administrative agent. The Company may borrow from time to time up to $3,000,000,000 in revolving credit loans under the 2026 Revolving Credit Agreement. The 2026 Revolving Credit Agreement matures on February 26, 2031, with one-year extension options subject to certain conditions, including certain lender approvals. Capitalized terms used in this section but not defined herein shall have the respective meanings set forth in the 2026 Revolving Credit Agreement.

Loans under the 2026 Revolving Credit Agreement will bear interest at (a) the Term SOFR determined for the interest period plus the applicable margin based on the credit rating of the Company for its long term senior unsecured debt (its “Credit Rating”) for SOFR Loans, (b) Alternate Base Rate (“ABR”) plus the applicable margin based on the Credit Rating for ABR Loans, (c) the Eurocurrency Rate plus the applicable margin based on the Credit Rating for Multicurrency Loans, and (d) for Competitive Advance Facility (“CAF”) Advances, at either (i) a fixed rate plus (or minus) a margin or (ii) the Eurocurrency Rate for CAF Advances denominated in an Available Foreign Currency (or Term SOFR, for Dollar-denominated CAF Advances) plus (or minus) a margin, in each case as specified in the applicable CAF Advance Offer for CAF Advances. In addition, the Company will pay a facility fee based on the Company’s Credit Rating and the total amount of revolving credit commitments (generally irrespective of usage) under the 2026 Revolving Credit Agreement.

The 2026 Revolving Credit Agreement contains customary representations, warranties, and covenants. The 2026 Revolving Credit Agreement also contains customary events of default, which may result in the termination of Commitments and acceleration of any outstanding Loans.

The 2026 Revolving Credit Agreement requires that the Company maintain a Maximum Leverage Ratio of 3.75x; provided that for the four consecutive fiscal quarters ended immediately following the consummation of a Qualified Acquisition (any acquisition or series of related acquisitions for which the Indebtedness incurred to finance the purchase price plus any Indebtedness assumed exceeds $1,000,000,000 and for which the Company notifies the administrative agent that such transaction is a Qualified Acquisition under the 2026 Revolving Credit Agreement), the Maximum Leverage Ratio shall be 4.75x, and shall be decreased to 4.50x, 4.25x, and 4.00x, for each of the next three fiscal quarter-ends after such four fiscal quarter-ends, respectively, and then to 3.75x for each fiscal quarter-end thereafter. The Company is permitted to exclude from Consolidated EBITDA, among other things, (i) any Non-Cash Charges, and (ii) any Cash Litigation Payments provided that the aggregate amount of such Cash Litigation Payments since December 31, 2025 shall not exceed $1,160,000,000.

A copy of the 2026 Revolving Credit Agreement is attached hereto as Exhibit 10.1 and is incorporated herein by reference. The foregoing description of the 2026 Revolving Credit Agreement is qualified in its entirety by reference to the full text of the 2026 Revolving Credit Agreement.

364-Day Revolving Credit Agreement

On February 26, 2026, the Company entered into a $2.000 billion 364-day revolving credit agreement (the “364-Day Revolving Credit Agreement”) by and among the Company, as borrower, the several lenders party thereto, and Wells Fargo Bank, National Association, as administrative agent. The Company may borrow from time to time up to $2,000,000,000 in revolving credit loans under the 364-Day Revolving Credit Agreement. The 364-Day Revolving Credit Agreement matures on the date that is 364 days from the earlier of (i) the date that any loans under the 364-Day Revolving Credit Agreement are available to be drawn on, or (ii) the closing of the Company’s acquisition of Penumbra, Inc. (“Penumbra”), pursuant to that certain Agreement and Plan of Merger, dated as of January 14, 2026, (the “Merger Agreement” and the transactions contemplated thereby to be consummated by the Company, the “Acquisition”), by and among the Company, Pinehurst Merger Sub, Inc., a subsidiary of the Company, and Penumbra. Capitalized terms used in this section but not defined herein shall have the respective meanings set forth in the 364-Day Revolving Credit Agreement.

Loans under the 364-Day Revolving Credit Agreement will bear interest at (a) Term SOFR determined for the interest period plus the applicable margin based on the Credit Rating for SOFR Loans, (b) ABR plus the applicable margin based on the Credit Rating for ABR Loans, and (c) the Eurocurrency Rate plus the applicable margin based on the Credit Rating for Multicurrency Loans. In addition, the Company will pay a facility fee based on the Company’s Credit Rating and the total amount of revolving credit commitments (generally irrespective of usage) under the 364-Day Revolving Credit Agreement. The Company will also pay a ticking fee based on the Credit Rating on the undrawn portion of the Commitments, accruing from 120 days after the effective date of the 364-Day Revolving Credit Agreement.

The 364-Day Revolving Credit Agreement contains substantially similar representations, warranties, covenants, events of default, and financial covenants (including requirements with respect to the Maximum Leverage Ratio) as the 2026 Revolving Credit Agreement.

A copy of the 364-Day Revolving Credit Agreement is attached hereto as Exhibit 10.2 and is incorporated herein by reference. The foregoing description of the 364-Day Revolving Credit Agreement is qualified in its entirety by reference to the full text of the 364-Day Revolving Credit Agreement.

364-Day Delayed Draw Term Loan Agreement

On February 26, 2026, the Company entered into a $6.000 billion term loan credit agreement (the “Term Loan Credit Agreement” and together with the 2026 Revolving Credit Agreement and the 364-Day Revolving Credit Agreement, the “2026 Credit Agreements”) by and among the Company, as borrower, the several lenders party thereto, and Wells Fargo Bank, National Association, as administrative agent. Under the Term Loan Credit Agreement, the Company may borrow (i) a 364-day delayed draw term loan in an aggregate principal amount of up to $1.000 billion, which may be drawn to fund the Acquisition at Closing, and (ii) a 364-day delayed draw term loan in an aggregate principal amount of up to $5.000 billion, which may be drawn to fund the Acquisition at Closing and, if so drawn, shall be repaid or refinanced with the proceeds of any subsequent equity issuance or debt incurrence (subject to certain exceptions) by the Company. Capitalized terms used in this section but not defined herein shall have the respective meanings set forth in the Term Loan Credit Agreement.

The Tranche A Loans and Tranche B Loans may only be drawn on the Closing Date, which is the date on which the Acquisition is consummated and all conditions precedent to borrowing under the Term Loan Credit Agreement (including certain conditions precedent with respect to the Acquisition Agreement) have been satisfied or waived. Both tranches mature 364 days after the Closing Date. Tranche A Loans and Tranche B Loans, once repaid or prepaid, may not be reborrowed. Prior to the Closing Date, the Tranche B Commitments will be automatically reduced on a dollar-for-dollar basis by 100% of the net cash proceeds received by the Company from any equity issuance or debt incurrence (subject to certain exceptions). After the Closing Date, the Company is required to prepay outstanding Tranche B Loans on a dollar-for-dollar basis with 100% of the net cash proceeds received from any equity issuance or debt incurrence (subject to certain exceptions).

Loans under the Term Loan Credit Agreement will bear interest at (a) Term SOFR determined for the interest period plus the applicable margin based on the Credit Rating for SOFR Loans, and (b) ABR plus the applicable margin based on the Credit Rating for ABR Loans. In addition, the Company will pay a ticking fee based on the Credit Rating on the undrawn portion of the Tranche A Commitments and the Tranche B Commitments, in each case, accruing from 120 days after the effective date of the Term Loan Credit Agreement. The Company will also pay a duration fee equal to 0.10% per annum on the aggregate outstanding principal amount of Tranche B Loans, payable 90 days following the Closing Date.

The Term Loan Credit Agreement contains substantially similar representations, warranties, covenants, events of default, and financial covenants (including requirements with respect to the Maximum Leverage Ratio) as the 2026 Revolving Credit Agreement and the 364-Day Revolving Credit Agreement.

A copy of the Term Loan Credit Agreement is attached hereto as Exhibit 10.3 and is incorporated herein by reference. The foregoing description of the Term Loan Credit Agreement is qualified in its entirety by reference to the full text of the Term Loan Credit Agreement.
