**EXPLANATORY NOTE** 

On February 16, 2026, Danaher Corporation ("Danaher" or the "Registrant"), Masimo Corporation ("Masimo") and Mobius Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Registrant ("Merger Sub"), entered into the Agreement and Plan of Merger, pursuant to which Merger Sub will merge with and into Masimo, with Masimo surviving the Merger as a wholly owned subsidiary of the Registrant (the "Merger").

In connection with the Merger, each restricted stock unit (an "RSU") in respect of shares of Masimo common stock that are granted and outstanding as of immediately prior to the effective time of the Merger (the "Rollover RSUs") under the Masimo Corporation 2017 Equity Incentive Plan (as amended, the "Masimo Plan"), will be assumed by the Registrant and converted into RSUs in respect of shares of the Registrant's common stock, par value $0.01 per share ("Common Stock") subject to substantially the same terms and conditions as were applicable to the Rollover RSUs with respect to a number of shares of Common Stock determined by multiplying the number of Rollover RSUs immediately prior to the effective time of the Merger by $180.00 in cash, without interest, divided by the volumed weighted average trading price per share of Common Stock for the 10-day trading period ending on and including the closing date, as reported by the New York Stock Exchange.

This Registration Statement on Form S-8 (this "Registration Statement") is being filed by the Registrant to register the offer and sale of up to 752,000 shares of Common Stock that may be issued pursuant to the Masimo Plan, which shares of Common Stock represent the number of shares of Masimo common stock issuable upon vesting of the Rollover RSUs, adjusted pursuant to the terms of the Merger Agreement described above.

**Item 1. Plan Information.**

In accordance with the instructions of Part I of Form S-8, such documents are not being filed with the Securities and Exchange Commission (the "Commission") either as part of this Registration Statement or as prospectuses or prospectus supplements pursuant to Rule 424 of the Securities Act. Such documents and the documents incorporated by reference in this Registration Statement pursuant to Item 3 of Part II of Form S-8, taken together, constitute a prospectus that meets the requirements of Section 10(a) of the Securities Act.

Notwithstanding the foregoing, unless specifically stated to the contrary, none of the information that the Registrant discloses under Items 2.02 or 7.01 of any Current Report on Form 8-K that it may from time to time furnish to the Commission will be incorporated by reference into, or otherwise included in, this Registration Statement.

Any statement, including financial statements, contained in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or therein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

**Item 4. Description of Securities.** 

Not applicable.

**Item 5. Interests of Named Experts and Counsel.** 

Not applicable.

**Item 6. Indemnification of Directors and Officers.** 

Section 145 of the General Corporation Law of the State of Delaware ("DGCL") provides, generally, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (except actions by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. A corporation may similarly indemnify such person for expenses actually and reasonably incurred by such person in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation, provided that a court shall have determined, upon application, that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

Section 102(b)(7) of the DGCL provides, generally, that the certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, provided that such provision may not eliminate or limit the liability of (i) a director or officer for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) a director under section 174 of the DGCL, (iv) a director or officer for any transaction from which the director derived an improper personal benefit or (v) an officer in any action by or in the right of the corporation. No such provision may eliminate or limit the liability of a director or officer for any act or omission occurring prior to the date when such provision became effective.

------

Article Nine of Danaher's Restated Certificate of Incorporation provides that Danaher will indemnify its directors and officers to the full extent authorized or permitted by law and that no director shall be personally liable for monetary damages to Danaher or its stockholders for any breach of fiduciary duty by such director as a director, except to the extent provided by applicable law (i) for any breach of the director's duty of loyalty to Danaher or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL, or (iv) for any transaction from which such director derived an improper personal benefit. Article Eight of Danaher's Amended and Restated By-Laws provides that Danaher will indemnify directors and officers of Danaher in non-derivative claims if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of Danaher, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. For non-derivative claims, termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, in itself, create a presumption that the person did not act in good faith and in a manner which such person believed to be in or not opposed to the best interests of Danaher, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person's conduct was unlawful. For derivative claims, Article Eight of Danaher's By-Laws provides that Danaher will indemnify directors and officers of Danaher if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of Danaher; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to Danaher unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

In addition to the above, Danaher has entered into indemnification agreements with each of its directors and executive officers. The indemnification agreements provide for substantially similar indemnification rights and provide that Danaher will agree to pay expenses in advance of the final disposition of any proceeding for which indemnification is claimed. Danaher also provides indemnity insurance pursuant to which officers and directors are indemnified or insured against liability or loss under certain circumstances, which may include liability or related loss under the Securities Act and the Exchange Act.

**Item 7. Exemption from Registration Claimed.** 

Not applicable.

**Item 8. Exhibits.** 

See Exhibit Index.

**Item 9. Undertakings.** 

(a) The undersigned Registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to the
Registration Statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement
(or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in
volume of securities offered (if the total dollar value of securities offered would not exceed

------

that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the
Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment
shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which
remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the
Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors,
officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: <u>Registration Statement on Form S-8</u> 

Ladies and Gentlemen:

We are acting as special counsel to Danaher Corporation, a Delaware corporation (the "<u>Company</u>"), in connection with the filing by the Company of a Registration Statement on Form S-8 (the "<u>Registration Statement</u>") under the Securities Act of 1933, as amended (the "<u>Act</u>"), with the Securities and Exchange Commission (the "<u>Commission</u>") covering the offering of up to 752,000 shares (the "<u>Plan Shares</u>") of common stock, par value $0.01 per share (the "<u>Common Stock</u>"), of the Company issuable pursuant to restricted stock units initially granted by Masimo Corporation ("<u>Masimo</u>") pursuant to the Masimo Corporation 2017 Equity Incentive Plan (as amended, the "<u>Masimo Plan</u>") and outstanding as of immediately prior to the effective time of the merger (the "Merger") pursuant to the Agreement and Plan of Merger, dated as of February 16, 2026, by and among the Company, Masimo Corporation and Mobius Merger Sub, Inc., which restricted stock units of Masimo will be assumed by the Company and converted into restricted stock units with respect to shares of the Company's Common Stock at the effective time of the Merger.

For purposes of this letter, we have examined such documents, records, certificates, resolutions and other instruments deemed necessary as a basis for this opinion, and we have assumed the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity of the originals of all documents submitted to us as copies.

Based upon and subject to the foregoing qualifications, assumptions and limitations and the further limitations set forth herein, we advise you that the Plan Shares are duly authorized and when the Plan Shares have been duly issued pursuant to and in accordance with the terms and conditions of the applicable Masimo Plan and the Company's Restated Certificate of Incorporation and Amended and Restated By-laws, the Plan Shares will be validly issued, fully paid and non-assessable.

Our opinions expressed above are subject to the qualifications that we express no opinion as to the applicability of, compliance with, or effect of any laws except the General Corporation Law of the State of Delaware.

We have relied without independent investigation upon, among other things, an assurance from the Company that the number of shares which the Company is authorized to issue in its Restated Certificate of Incorporation exceeds the number of shares outstanding and the number of shares which the Company is obligated to issue (or had otherwise reserved for issuance) for any purposes other than issuances of the Plan Shares by at least the number of Plan Shares and we have assumed that such condition will remain true at all future times relevant to this opinion.

We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.

We do not find it necessary for the purposes of this opinion, and accordingly we do not purport to cover herein, the application of the securities or "Blue Sky" laws of the various states to the issuance and sale of the Plan Shares.

This opinion is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein. We assume no obligation to revise or supplement this opinion should the General Corporation Law of the State of Delaware be changed by legislative action, judicial decision or otherwise.

This opinion is furnished to you in connection with the filing of the Registration Statement, and is not to be used, circulated, quoted or otherwise relied upon for any other purposes.

Sincerely,

/s/ Kirkland & Ellis LLP
