Ladies and Gentlemen:

We have acted as counsel to CURO Group Holdings Corp., a corporation organized under the laws of the State of Delaware (the “Company”), in connection with the preparation of a Registration Statement on Form S-1 initially filed with the U.S. Securities and Exchange Commission on May 14, 2018 (as amended, the “Registration Statement”) under the Securities Act of 1933 (as amended, the “Act”), relating to the offer and sale by the selling stockholders of the Company named therein (the “Selling Stockholders”) of 5,000,000 shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”) and up to an additional 750,000 shares of Common Stock subject to the exercise of the underwriters’ option to purchase additional shares (collectively, the “Shares”).

We have examined copies of the amended and restated certificate of incorporation of the Company, the amended and restated bylaws of the Company, the Registration Statement, all relevant resolutions adopted by the Company’s board of directors and such other records and documents that we have deemed necessary for the purpose of this opinion. We have also examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of such other documents, corporate records, papers, statutes and authorities as we have deemed necessary to form a basis for the opinions hereinafter expressed.

As to questions of fact material to the opinions expressed below, we have relied without independent check or verification upon certificates and comparable documents of public officials and officers and representatives of the Company and statements of fact contained in the documents we have examined. In our examination and in rendering our opinions contained herein, we have assumed (i) the genuineness of all signatures of all parties; (ii) the authenticity of all corporate records, documents, agreements, instruments and certificates submitted to us as originals and the conformity to original documents and agreements of all documents and agreements submitted to us as conformed, certified or photostatic copies; and (iii) the capacity of natural persons.

Based on the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that the Shares to be sold by the Selling Stockholders have been duly authorized and are validly issued, fully paid and non-assessable.
