Re:

Ladies and Gentlemen:
 
We have acted as special counsel to Nkarta, Inc., a Delaware corporation (the “Company”), in connection with the preparation of the Registration Statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) on the date hereof under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the offer and sale from time to time by the Company, pursuant to the sales agreement, dated as of March 25, 2026 (the “Sales Agreement”), between the Company and Stifel, Nicolaus & Company, Incorporated, as the sales agent, of shares of the Company’s common stock, par value $0.0001 per share, having an aggregate offering price of up to $100,000,000 (the “Shares”).
 
In our capacity as such counsel, we have examined originals or copies of those corporate and other records and documents we considered appropriate. We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with originals of all documents submitted to us as copies.
 
We have also assumed that the Shares, when issued, will be issued in accordance with and not in violation of any terms and conditions established by the Board of Directors or any committee thereof in the resolutions adopted by the Board of Directors or any such committee thereof with respect to the issuance of the Shares (such approvals are referred to hereinafter as the “Corporate Approvals”).
 
On the basis of such examination and subject to the limitations and qualifications in this letter, we are of the opinion that the issuance and sale of the Shares have been duly authorized by all necessary corporate action on the part of the Company, and upon payment for and delivery of the Shares pursuant to the terms of the Sales Agreement and in accordance with the Corporate Approvals, the Shares will be validly issued, fully paid and non-assessable.
 
The law covered by this letter is limited to the present General Corporation Law of the State of Delaware. We express no opinion as to the laws of any other jurisdiction and no opinion regarding the statutes, administrative decisions, rules, regulations or requirements of any county, municipality, subdivision or local authority of any jurisdiction.
