The Credit Facility expires on April 15, 2027 (the “Scheduled Termination Date”). Danaher may elect, upon the payment of a fee equal to 0.50% of the principal amount of the loans then outstanding and upon the satisfaction of certain conditions, to convert any loans outstanding on the Scheduled Termination Date into term loans that are due and payable one year following the Scheduled Termination Date. The description of the Credit Agreement with respect to the Credit Facility (the “Credit Agreement”) set forth herein is qualified in its entirety by reference to the full text of the Credit Agreement, a copy of which is attached as Exhibit 10.1 hereto and is incorporated by reference herein. Borrowings under the Credit Facility bear interest as follows: (i) Term SOFR Loans (as defined in the Credit Agreement) bear interest at a variable rate equal to the Term SOFR (as defined in the Credit Agreement) plus a margin of between 58.5 and 108.5 basis points, depending on Danaher’s long-term debt credit rating; and (ii) Base Rate Loans (as defined in the Credit Agreement) bear interest at a variable rate equal to the highest of (a) the Federal funds rate (as published by the Federal Reserve Bank of New York from time to time) plus 1/2 of 1%, (b) Bank of America’s “prime rate” as publicly announced from time to time, (c) Term SOFR (based on one-month interest period plus 1%) and (d) 1.0%, plus in each case a margin of between 0 to 8.5 basis points depending on Danaher’s long-term debt credit rating. In addition, Danaher is required to pay a per annum facility fee of 4.0 basis points based on the aggregate commitments under the Credit Facility, regardless of usage. The Credit Facility requires Danaher to maintain a Consolidated Leverage Ratio (as defined in the Credit Agreement) of 0.65 to 1.00 or less. Borrowings under the Credit Facility are prepayable at Danaher’s option at any time in whole or in part without premium or penalty. Danaher’s obligations under the Credit Facility are unsecured. Danaher has unconditionally and irrevocably guaranteed the obligations of each of its subsidiaries in the event a subsidiary is named a borrower under the Credit Facility. The Credit Agreement contains customary representations, warranties, conditions precedent, events of default, indemnities and affirmative and negative covenants, including covenants that, among other things, restrict the ability of Danaher and certain of its subsidiaries to: incur liens; sell or otherwise dispose of all or substantially all of Danaher’s or any subsidiary borrower’s assets; enter into certain mergers or consolidations; and use proceeds of borrowings under the Credit Facility for other than permitted uses. These covenants are subject to a number of important exceptions and qualifications. Certain changes of control with respect to Danaher would constitute an event of default under the Credit Facility. Upon the occurrence and during the continuance of an event of default, the lenders may declare the outstanding advances and all other obligations under the Credit Agreement immediately due and payable. Danaher intends to use the Credit Facility for liquidity support for Danaher’s U.S. dollar-denominated commercial paper program and for general corporate purposes.   ITEM 2.03 CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT The information set forth under Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.   ITEM 9.01 FINANCIAL STATEMENTS AND EXHIBITS (c) Exhibits:   Exhibit No.    Description 10.1    Credit Agreement, dated as of April 16, 2026, among Danaher Corporation, certain of its subsidiaries party thereto, Bank of America, N.A., as Administrative Agent, and the lenders referred to therein. 104    Cover Page Interactive Data File (formatted as inline XBRL with applicable taxonomy extension information contained in Exhibits 101)   SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.       DANAHER CORPORATION Date: April 17, 2026     By:   /s/ James F.
