Ladies and Gentlemen:

We have acted as counsel to Fox Corporation, a Delaware corporation (the “Company”), in connection with the preparation and filing with the United States Securities and Exchange Commission (the “Commission”) of the Company’s Registration Statement on Form S-4 filed on the date hereof (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of an aggregate of up to 172,257,523 shares of Class A Common Stock, par value $0.01 per share, of the Company (the “Company Class A Common Stock”), to be issued pursuant to and in connection with the transactions contemplated by that certain Agreement and Plan of Merger, dated as of June 14, 2026 (the “Merger Agreement”), by and among the Company, Falcon Merger Sub 1, Inc., Falcon Merger Sub 2, LLC, and Roku, Inc., which Merger Agreement is described in the Registration Statement and is included as Annex A to the joint proxy statement/prospectus forming part thereof.

In so acting, we have examined originals or copies (certified or otherwise identified to our satisfaction) of (i) the Registration Statement, (ii) the Merger Agreement, (iii) the Amended and Restated Certificate of Incorporation of the Company, (iv) the Amended and Restated By-laws of the Company and (v) such corporate records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers and representatives of the Company, and have made such inquiries of such officers and representatives, as we have deemed relevant and necessary as a basis for the opinions hereinafter set forth.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies and the authenticity of the originals of such latter documents. As to all questions of fact material to this opinion that have not been independently established, we have relied upon certificates or comparable documents of officers and representatives of the Company and upon the representations and warranties of the Company contained in the Merger Agreement.
