Re: Star Bulk Carriers Corp.

Ladies and Gentlemen:

We have acted as Republic of the Marshall Islands counsel to Star Bulk Carriers Corp. (the “Company”) and Star Infinity Corp. (“Merger Sub”), corporations organized under the laws of the Republic of the Marshall Islands, in connection with the preparation and filing with the U.S. Securities and Exchange Commission (the “Commission”), under the Securities Act of 1933, as amended (the “Securities Act”), of a registration statement on Form F-4 (File. No. 333-276621), as thereafter amended or supplemented (the “Registration Statement”), in respect of the issuance by the Company of up to 29,455,890 of the Company’s common shares, par value $0.01 per share, (the “Shares”) in exchange for all of the issued and outstanding common shares (the “Original Shares”) of Eagle Bulk Shipping Inc. (“Eagle”) pursuant to that certain Agreement and Plan of Merger by and among the Company, Merger Sub and Eagle dated as of December 11, 2023 (the “Merger Agreement”), which provides for the proposed merger of Eagle with and into Merger Sub (the “Merger”) with Eagle continuing as the surviving entity.

In connection with this opinion, we have examined originals or electronic copies, certified or otherwise identified to our satisfaction, of: (i) the Registration Statement; (ii) the Merger Agreement; (iii) the prospectus of the Company included in the Registration Statement (the “Prospectus”); (iv) the Fourth Amended and Restated Articles of Incorporation of the Company; (v) the Third Amended and Restated Bylaws of the Company; (vi) certain resolutions of the board of directors of the Company relating to the approval of the Merger Agreement and Merger contemplated thereby; and (vii) such corporate documents and records of the Company and such other instruments, certificates and documents as we have deemed necessary or appropriate as a basis for the opinions hereinafter expressed. In such examinations, we have assumed the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies or drafts of documents to be executed, the genuineness of all signatures and the legal competence or capacity of persons or entities to complete the execution of documents. As to various questions of fact which are material to the opinions hereinafter expressed, we have relied upon statements or certificates of public officials, directors or officers of the Company and others.

We have further assumed for the purposes of this opinion, without investigation, that (i) all documents contemplated by the Prospectus to be executed in connection with the Merger have been duly authorized, executed and delivered by each of the parties thereto other than the Company, and (ii) the terms of the Merger comply in all respects with the terms, conditions and restrictions set forth in the Merger Agreement and the Prospectus and all of the instruments, agreements and other documents relating thereto or executed in connection therewith.
