Ladies and Gentlemen:

We have acted as counsel to Addus HomeCare Corporation, a Delaware corporation (the “Company”), in connection with the Prospectus Supplement, dated June 26, 2024, as filed on June 28, 2024 (the “Prospectus Supplement”), filed under the Registration Statement on Form S-3, Registration No. 333-267253 (the “Registration Statement”), of the Company pursuant to the Securities Act of 1933, as amended (the “Securities Act”), relating to (i) the sale by the Company of 1,500,000 shares (the “Firm Shares”) of the Company’s common stock, par value $0.001 per share (“Common Stock”) and (ii) the sale by the Company, at the option of the Underwriters, of up to 225,000 additional shares of Common Stock (the “Optional Shares” and, collectively with the Firm Shares, the “Shares”), pursuant to the Underwriting Agreement, dated June 26, 2024 (the “Underwriting Agreement”), by and among the Company and BofA Securities, Inc. and Jefferies LLC, acting individually and as Representatives of the several Underwriters named in Schedule A to the Underwriting Agreement (the “Underwriters”). This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In connection with this opinion, we have reviewed the Registration Statement and the Prospectus Supplement. We have also reviewed such corporate documents and records of the Company and such other matters as we have deemed necessary or appropriate for purposes of this opinion. As to various issues of fact, we have relied upon the representations and statements of fact made in the documents that we have reviewed, and have made no independent verification or investigation.

We have assumed that all documents we have reviewed are the valid and binding obligations of and enforceable against the parties thereto. We have also assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the conformity to authentic original documents of all documents submitted to us as certified, facsimile, conformed, digitally scanned or photostatic copies and the legal capacities of all natural persons.

Based on the foregoing, and subject to the assumptions, limitations and qualifications set forth herein, we are of the opinion that:

(1) The Firm Shares have been duly authorized and, when issued and delivered by the Company against payment of the consideration set forth in the Underwriting Agreement, will be validly issued, fully paid and non-assessable.

(2) The Optional Shares have been duly authorized, and assuming the due and proper exercise of the Underwriters’ option in accordance with the terms of the Underwriting Agreement and, when issued and delivered by the Company pursuant to the Underwriting Agreement against payment of the consideration set forth therein, will be validly issued, fully paid and non-assessable.
