Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to NextPlat Corp, a Nevada corporation (the “Company”), in connection with a registration statement on Form S-3 (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) on November 21, 2022 under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the issuance and sale from time to time, pursuant to Rule 415 of the rules and regulations promulgated under the Securities Act, of an unspecified number or amount of the following securities of the Company: (i) common stock, par value $0.0001 per share (the “Common Stock”); (ii) preferred stock, par value $0.0001 per share (the “Preferred Stock”); (iii) debt securities, consisting of debentures, notes or other evidences of indebtedness in one or more series (“Debt Securities”); (iv) warrants to purchase Debt Securities, warrants to purchase Common Stock and warrants to purchase Preferred Stock (collectively, the “Warrants”); and (v) units comprised of Common Stock or Preferred Stock, Warrants to purchase Common Stock or Preferred Stock, Debt Securities or any combination of those securities (the “Units”). The Common Stock, Preferred Stock, Debt Securities, Warrants, and Units are collectively referred to herein as the “Securities.”

The Debt Securities are to be issued under an indenture, to the extent applicable,, to be entered into between the Company and a trustee chosen by the Company and qualified to act as such under the Trust Indenture Act of 1939, as amended (a “Trustee”), in a form filed as an exhibit to a post-effective amendment to the Registration Statement (each, an “Indenture” and collectively, the “Indentures”).

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In connection with our opinion, we have examined the Registration Statement, including the exhibits thereto, and such other documents, corporate records and instruments, and have examined such laws and regulations, as we have deemed necessary for the purposes of this opinion. In making our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity with the originals of all documents submitted to us as copies and the legal capacity of all natural persons. As to matters of fact material to our opinions in this letter, we have relied on certificates and statements from officers and other employees of the Company, public officials and other appropriate persons.

In rendering the opinions in this letter we have assumed, without independent investigation or verification, that each party to each of the documents executed or to be executed, other than the Company, (a) is validly existing and in good standing under the laws of its jurisdiction of organization, (b) has full power and authority to execute such documents to which it is a party and to perform its obligations thereunder, (c) has taken all necessary action to authorize execution of such documents on its behalf by the persons executing same, (d) has properly executed and delivered, or will properly execute and deliver, each of such documents to which it is a party, and (e) has duly obtained all consents or approvals of any nature from and made all filings with any governmental authorities necessary for such party to execute, deliver or perform its obligations under such documents to which it is a party. In addition, in rendering such opinions we have assumed, without independent investigation or verification, (i) that the execution and delivery of, and performance of their respective obligations under, the documents executed or to be executed by each party thereto, other than the Company, do not violate any law, rule, regulation, agreement or instrument binding upon such party and (ii) that each of such documents is the legal, valid and binding obligation of, and enforceable against, each party thereto, other than the Company.
