Re: | Prospectus Supplement to Registration Statement on Form S-3 |
Ladies and Gentlemen:
This opinion is furnished to you in connection with (i) the Registration Statement on Form S-3 (File No. 333-261708) (the “Registration Statement”) filed by Sage Therapeutics, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), for the registration of, among other things, an indeterminate number of shares of common stock, par value $0.0001 per share (the “Common Stock”) of the Company which may be issued from time to time on a delayed or continuous basis by the Company pursuant to Rule 415 under the Securities Act, as set forth in the Registration Statement and the prospectus contained therein (the “Base Prospectus”) and (ii) the prospectus supplement, dated November 7, 2023 (the “Prospectus Supplement” and, together with the Base Prospectus, the “Prospectus”) relating to the issuance and sale from time to time by the Company of shares of Common Stock having an aggregate offering price of up to $250,000,000 (the “Shares”). The Shares are to be issued and sold pursuant to a Sales Agreement, dated November 7, 2023, between the Company and Cowen and Company, LLC (the “Sales Agreement”). We are acting as counsel for the Company in connection with the issue and sale by the Company of the Shares.
We have examined and relied upon copies of the Registration Statement and the Prospectus as filed with the Commission. We have also examined and relied upon the Sales Agreement, the Fifth Amended and Restated Certificate of Incorporation of the Company, the Amended and Restated Bylaws of the Company, and minutes of meetings of the stockholders and the Board of Directors of the Company, including committees thereof, as provided to us by the Company, and such other documents as we have deemed necessary for purposes of rendering the opinion hereinafter set forth.
In our examination of the foregoing documents, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, the authenticity of the originals of such latter documents and the legal competence of all signatories to such documents.
We express no opinion herein as to the laws of any state or jurisdiction other than the state laws of the Commonwealth of Massachusetts, the General Corporation Law of the State of Delaware and the federal laws of the United States of America.
Based upon and subject to the foregoing, we are of the opinion that the Shares have been duly authorized for issuance and, when the Shares have been issued and paid for in accordance with the terms and conditions of the Sales Agreement, the Shares will be validly issued, fully paid and non-assessable.
