and (9) such other corporate records, certificates and other documents (including a receipt executed on behalf of NEE acknowledging receipt of the purchase price for the Corporate Units and a receipt executed on behalf of NEE Capital acknowledging receipt of the purchase price for the Debentures) and such questions of law as we have considered necessary or appropriate for the purposes of this opinion.

Based on the foregoing, we are of the opinion that:

1. The Debentures and the Guarantee, as it relates to the Debentures, are legally issued, valid, and binding obligations of NEE Capital and NEE, respectively, except as limited or affected by bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance or other laws affecting creditors’ rights and remedies generally and general principles of equity and to concepts of materiality, reasonableness, good faith and fair dealing and the discretion of the court before which any matter is brought.

2. The Corporate Units are legally issued, valid, and binding obligations of NEE, except as limited or affected by bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance or other laws affecting creditors’ rights and remedies generally and general principles of equity and to concepts of materiality, reasonableness, good faith and fair dealing and the discretion of the court before which any matter is brought.

3. The Purchase Contracts are valid and binding obligations of NEE, except as limited or affected by bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance or other laws affecting creditors’ rights and remedies generally and general principles of equity and to concepts of materiality, reasonableness, good faith and fair dealing and the discretion of the court before which any matter is brought.

4. The Common Stock issuable pursuant to the Purchase Contracts, when issued and delivered by NEE against payment therefor in accordance with the provisions of the Purchase Contract Agreement, the Purchase Contracts and the Pledge Agreement, will be validly issued, fully paid and non‑assessable.

5. Our opinions as to United States federal income tax matters are as set forth in the Prospectus Supplement under the heading “Material United States Federal Income Tax Consequences”, subject to the qualifications set forth therein.

In rendering the foregoing opinions, we have assumed that: (1) the certificates representing the Debentures conform to a specimen examined by us and that the Debentures have been duly authenticated, in accordance with the Indenture, by the Trustee under the Indenture; (2) the certificates representing the Corporate Units conform to a specimen examined by us and the Corporate Units have been duly authenticated, in accordance with the Purchase

Contract Agreement, by the Purchase Contract Agent; (3) the certificates representing the shares of Common Stock issuable pursuant to the Purchase Contracts will be in the form or in substantially the form currently used by the Company for shares of Common Stock issued in certificated form, and a direct registration advice will be in the form or in substantially the form used by the Registrar and Transfer Agent for shares of Common Stock issued without certificates; and (4) the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

We hereby consent to the references to us in the Base Prospectus under the heading “Legal Opinions” and in the Prospectus Supplement under the heading “Material United States Federal Income Tax Consequences,” to the references to us in the Registration Statement and to the filing of this opinion as an exhibit to a Current Report on Form 8‑K to be filed with the Commission by NEE on or about October 31, 2024, which will be incorporated by reference in the Registration Statement. In giving the foregoing consents, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.

This opinion is limited to the laws of the States of New York and Florida and the federal laws of the United States insofar as they bear on matters covered hereby. As to all matters of Florida law, we have relied, with your consent, upon an opinion of even date herewith addressed to you by Squire Patton Boggs (US) LLP. As to all matters of New York law, Squire Patton Boggs (US) LLP is hereby authorized to rely upon this opinion as though it were rendered to Squire Patton Boggs (US) LLP.
