| Registration Statement on Form S-1 |
Ladies and Gentlemen:
We have acted as counsel to Spyre Therapeutics, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-1 (the “Registration Statement”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), relating to the resale from time to time by the selling stockholders named therein of (i) up to 22,496,402 shares (the “Common Shares”) of the Company’s common stock, par value $0.0001 per share (“Common Stock”) and (ii) 10,865,000 shares (the “Conversion Shares”) of Common Stock issuable upon the conversion of 271,625 shares of the Company’s Series B preferred stock, par value $0.0001 per share (the “Preferred Stock”).
In arriving at the opinion expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction as being true and complete copies of the originals, of the specimen common stock certificates and such other documents, corporate records, certificates of officers of the Company and of public officials and other instruments as we have deemed necessary or advisable to enable us to render these opinions. In our examination, we have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies.
Based on the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that the Common Shares are validly issued, fully paid and non-assessable and the Conversion Shares, when issued upon the conversion of the Preferred Stock, will be validly issued, fully paid and non-assessable.
