Ladies and Gentlemen:

We have acted as counsel to Viking Therapeutics, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b) of the rules and regulations of the Securities Act of 1933, as amended (the “Act”), of a prospectus supplement, dated February 28, 2024 (the “Prospectus Supplement”), to the Company’s Registration Statement on Form S-3ASR (File No. 333-273460) filed with the Commission under the Act on July 26, 2023 (the “Registration Statement”), and the related prospectus, dated July 26, 2023, included in the Registration Statement at the time it originally became effective (the “Base Prospectus” and, together with the Prospectus Supplement, the “Prospectus”), relating to the offering by the Company of up to 6,471,000 shares (the “Firm Shares”) of the Company’s common stock, par value $0.00001 per share (the “Common Stock”), and up to an additional 970,650 shares of Common Stock (the “Option Shares” and together with the Firm Shares, the “Securities”) subject to an option to purchase additional shares granted to the underwriters of the offering. The Securities are being sold to the several underwriters named in, and pursuant to, an underwriting agreement among the Company and Morgan Stanley & Co. LLC and Leerink Partners LLC, as the representatives of such underwriters, dated as of February 28, 2024 (the “Underwriting Agreement”).

In connection with this opinion, we have examined and relied upon the Registration Statement, the Prospectus, the Underwriting Agreement, the Company’s Amended and Restated Certificate of Incorporation and the Company’s Amended and Restated Bylaws, each as currently in effect, and the originals or copies certified to our satisfaction of such records, documents, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below. As to certain factual matters, we have relied upon a certificate of an officer of the Company and have not independently verified such matters. We have assumed the genuineness and authenticity of all documents submitted to us as originals, and the conformity to originals of all documents submitted to us as copies thereof.

Our opinion is limited to the matters stated herein and no opinion is implied or may be inferred beyond the matters expressly stated. Our opinion herein is expressed solely with respect to the federal laws of the United States and the General Corporation Law of the State of Delaware. We are not rendering any opinion as to compliance with any federal or state antifraud law, rule or regulation relating to securities, or to the sale or issuance thereof. Our opinion is based on these laws as in effect on the date hereof, and we disclaim any obligation to advise you of facts, circumstances, events or developments which hereafter may be brought to our attention and which may alter, affect or modify the opinion expressed herein. We express no opinion as to whether the laws of any particular jurisdiction other than those identified above are applicable to the subject matter hereof.
