Senior Notes

On May 10, 2024, the Company issued $3,300.0 million in aggregate principal amount of senior unsecured notes comprised of $700.0 million aggregate principal amount of 5.197% Senior Notes due 2027 (the “2027 Notes”), $750.0 million aggregate principal amount of 5.176% Senior Notes due 2029 (the “2029 Notes”), $500.0 million aggregate principal amount of 5.314% Senior Notes due 2031 (the “2031 Notes”), $750.0 million aggregate principal amount of 5.450% Senior Notes due 2034 (the “2034 Notes”) and $600.0 million aggregate principal amount of 5.700% Senior Notes due 2054 (the “2054 Notes” and, together with the 2027 Notes, 2029 Notes, 2031 Notes and 2034 Notes, the “New Notes,” and collectively with the existing senior unsecured notes, the “Senior Notes”). The Company used the net proceeds of the 2034 Notes and the 2054 Notes to repay in full all indebtedness under, and terminate all commitments and discharge and release all guarantees in respect of, the Company’s former senior secured credit facilities and used the remaining net proceeds of such New Notes for general corporate purposes. The Company used the net proceeds of the 2027 Notes, the 2029 Notes and the 2031 Notes to partially fund the cash consideration of the acquisition of ILC Dover, with any remaining cash consideration funded with cash on hand. The New Notes were issued pursuant to a base indenture, dated as of August 14, 2023 (the “Base Indenture”), between the Company and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), as supplemented by the third supplemental indenture (the “Supplemental Indenture” and, together with the Base Indenture, the “New Indenture”) dated as of May 10, 2024, between the Company and the Trustee. The interest payment dates for the New Notes are June 15 and December 15 of each year, with interest payable in arrears.

On August 14, 2023, the Company completed its issuance of $1,500.0 million in aggregate principal amount of senior unsecured notes comprised of $500.0 million aggregate principal amount of 5.400% Senior Notes due August 2028 (the “2028 Senior Notes”) and $1,000.0 million aggregate principal amount of 5.700% Senior Notes due August 2033 (the “2033 Senior Notes” and, together with the 2028 Senior Notes, the “Existing Notes”). The Company used the proceeds of the offering of the Existing Notes to repay a portion of the amounts outstanding under its former senior secured credit facilities. The Existing Notes were issued pursuant to the Base Indenture, as supplemented by a 2028 Supplemental Indenture No. 1 with respect to the 2028 Senior Notes and a 2033 Senior Notes Supplemental Indenture No. 1 with respect to the 2033 Senior Notes, each dated as of August 14, 2023, between the Company and the Trustee (collectively, the “Existing Indenture”). The interest payment dates for the Senior Notes are February 14 and August 14 of each year, with interest payable in arrears.

Prior to (i) May 15, 2027, in the case of the 2027 Notes, (ii) July 14, 2028, in the case of the 2028 Senior Notes, (iii) May 15, 2029, in the case of the 2029 Notes, (iv) April 15, 2031, in the case of the 2031 Notes, (v) May 14, 2033, in the case of the 2033 Senior Notes, (vi) March 15, 2034, in the case of the 2034 Notes, and (vii) December 15, 2053, in the case of the 2054 Notes, the Company may redeem the Senior Notes of a series at its option, in whole or in part, at any time from time to time, at a “make-

whole” premium, plus accrued and unpaid interest thereon to, but not including, the redemption date. On or after (i) May 15, 2027, in the case of the 2027 Notes, (ii) July 14, 2028, in the case of the 2028 Senior Notes, (iii) May 15, 2029, in the case of the 2029 Notes, (iv) April 15, 2031, in the case of the 2031 Notes, (v) May 14, 2033, in the case of the 2033 Senior Notes, (vi) March 15, 2034, in the case of the 2034 Notes, and (vii) December 15, 2053, in the case of the 2054 Notes, the Company may redeem the Senior Notes of a series at its option, in whole or in part, at any time from time to time, at a price equal to 100% of the principal amount of the Senior Notes of such series to be redeemed, plus accrued and unpaid interest thereon to, but not including, the redemption date. Additionally, if the Company experiences certain types of change of control transactions, the Company must offer to repurchase the Senior Notes at 101% of the aggregate principal amount of the Senior Notes repurchased (or such higher amount as the Company may determine) plus accrued and unpaid interest thereon to, but not including, the date of repurchase.

The Senior Notes are senior unsecured obligations of the Company and rank equally in right of payment with all of the Company’s other senior unsecured indebtedness from time to time outstanding, senior in right of payment to all of the Company’s subordinated indebtedness from time to time outstanding, and effectively junior to all of the indebtedness and other liabilities of the Company’s subsidiaries from time to time outstanding and to all of the Company’s secured indebtedness from time to time outstanding to the extent of the value of the assets securing such secured indebtedness.

The Existing Indenture and New Indenture contain covenants that limit the Company’s (and its subsidiaries’) ability to, among other things: (i) create liens on certain assets; (ii) consolidate, merge, sell or otherwise dispose of all or substantially all of its consolidated assets; and (iii) enter into sale and leaseback transactions with respect to certain assets, as well as customary events of default and covenants for an issuer of investment grade debt securities.

Revolving Credit Facility

On May 10, 2024, the Company entered into a credit agreement (the “Revolving Credit Facility”), with the lenders party thereto and Citibank, N.A., as administrative agent. The Revolving Credit Facility provides for a senior unsecured revolving facility in an aggregate committed amount of $2,600 million, a portion of which is available for the issuance of letters of credit in U.S. dollars, EUR or GBP. The Revolving Credit Facility will mature on May 10, 2029, subject to up to two additional one-year extensions pursuant to the terms of the Revolving Credit Facility.

Borrowings under the Revolving Credit Facility (other than borrowings in EUR or GBP) bear interest at a rate determined, at the Company’s option, based on either (i) an alternate base rate or (ii) a Term SOFR rate with a 0.10% per annum Term SOFR adjustment, plus, in each case, an applicable margin that varies depending on the credit rating of the Company. Borrowings under the Revolving Credit Facility in EUR (if any) bear interest at a EURIBOR rate, plus, in each case, an applicable margin that varies depending on the credit rating of the Company. Borrowings under the Revolving Credit Facility in GBP (if any) bear interest at a daily simple SONIA rate plus, in each case, an applicable margin that varies depending on the credit rating of the Company.

The financial covenant in the Revolving Credit Facility requires the Company to maintain, as of the last day of each fiscal quarter, a ratio of adjusted consolidated total net debt to consolidated adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”) of not more than 3.50 to 1.00, provided that the Company may elect to increase such ratio to 4.00 to 1.00 following a qualified acquisition up to two times, each for a period of four fiscal quarters beginning with the quarter during which such qualified acquisition is consummated (and if the second election occurs during the first increase period, such increase will be effective for a total of eight consecutive fiscal quarters).

As of June 30, 2025, the aggregate amount of commitments under the Revolving Credit Facility was $2,600.0 million and the capacity under the Revolving Credit Facility to issue letters of credit was $200.0 million. As of June 30, 2025, the Company had no outstanding borrowings under the Revolving Credit Facility, no outstanding letters of credit under the Revolving Credit Facility and unused availability under the Revolving Credit Facility of $2,600.0 million.

As of June 30, 2025, we were in compliance with all covenants under our Senior Notes and Revolving Credit Facility.

Commercial Paper Program

On August 13, 2024, the Company established a commercial paper program (the “Commercial Paper Program”), pursuant to which it may issue short-term, unsecured commercial paper notes in a maximum aggregate principal amount of $2,600 million, with maturities of up to 397 days from the date of issuance. The proceeds of the notes issued under the Commercial Paper Program may be used for various purposes including acquisitions. The Company had no outstanding borrowings under the Commercial Paper Program as of June 30, 2025.
