Ladies and Gentlemen:

We have acted as counsel to Newton Golf Company Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing of a prospectus supplement dated October 24, 2025 (the “Prospectus Supplement”) to the prospectus dated September 23, 2024 (together with the Prospectus Supplement, the “Prospectus”), related to the offering of up to $10,000,000 of common stock, par value $0.01 per share (“Common Stock”), that may be issued and sold (the “Shares”) under an At the Market Offering Agreement entered into by the Company with Kingswood Capital Partners, LLC on October 24, 2025 (the “Sales Agreement”). The Prospectus forms a part of the Company’s Registration Statement on Form S-3 (File No. 333-281664) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), on August 20, 2024, as amended on September 10, 2024 (as amended, the “Registration Statement”).

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K.

As counsel for the Company, we are familiar with the Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and the Amended and Restated Bylaws (the “Bylaws”) of the Company, each as amended to the date hereof, and we have reviewed originals, or copies certified or otherwise authenticated to our satisfaction, of (i) the Registration Statement, (ii) the Prospectus, (iii) the Sales Agreement and (iv) the proceedings taken by the Company in connection with the authorization of the Sales Agreement and the issuance and sale of the Shares. We have also examined originals, or copies certified or otherwise authenticated to our satisfaction, of such corporate records of the Company and other instruments, certificates of public officials and representatives of the Company, and other documents as we have deemed necessary as a basis for the opinions hereinafter expressed and have made such examination of statutes and decisions and reviewed such questions of law as we have considered necessary or appropriate for the purposes of this opinion letter.

Based on and subject to the foregoing and to the other assumptions, qualifications and limitations set forth herein, we are of the opinion that the issuance of the Shares have been duly authorized, and when (i) the Shares have been issued by the Company against payment of the agreed-upon consideration therefor in accordance with the provisions of the Sales Agreement, and (ii) certificates representing the Shares have been duly executed by the duly authorized officers of the Company, countersigned by the transfer agent therefor and delivered to the purchasers thereof (or in the case of Shares issued without certificates, the due registration of issuance and constructive delivery through book entry of such Shares), then, upon the happening of such events, such Shares will be validly issued, fully paid and non-assessable.

The foregoing opinions assume that (a) the Registration Statement and any amendments relating thereto will continue to be effective, (b) the Company will remain duly organized, validly existing and in good standing under the laws of the State of Delaware, (c) at the time any Shares are issued, (i) there will not have occurred any change in the law or in the Certificate of Incorporation or Bylaws affecting the issuance of such Shares, and (ii) no relevant corporate actions will have been modified or rescinded, (d) the Shares will be issued within the limits of the then remaining authorized but unreserved and unissued amounts of Common Stock under the Certificate of Incorporation, (e) all certificates evidencing any Shares will be in the form required by law and approved for issuance by the Company, (f) the Company will comply with all applicable notice requirements regarding uncertificated shares provided in the General Corporation Law of the State of Delaware, and (g) future issuances of Shares will be made in accordance with the parameters established by the Board of Directors or a Pricing Committee of the Board of Directors, as such parameters may be established from time to time.
