&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. resolutions, minutes of meetings, and corporate records of actions taken by the Board of Directors of the Company (the "<u>Board</u>") and committees thereof, as furnished and certified to us by the Company.

In making our examination, we have assumed (i) that all signatures on documents examined by us are genuine; (ii) the authenticity of all documents submitted to us as originals; (iii) the conformity with the original documents of all documents submitted to us as certified, conformed, electronic or photostatic copies; (iv) that each individual signing in a representative capacity (other than on behalf of the Company) any document reviewed by us had authority to sign in such capacity; (v) that each individual signing in a representative capacity any document reviewed by us had legal capacity to sign in such capacity; (vi) the truth, accuracy, and completeness of the information, representations, and warranties contained in the records, documents, instruments, and certificates we have reviewed; (vii) that the Registration Statement, Prospectus and the organizational documents of the Company, each as amended to the date hereof, will not have been amended from the date hereof in a manner that would affect the validity of the opinion rendered herein; and (viii) the accuracy, completeness and authenticity of certificates of public officials.

In connection with the opinion hereinafter expressed, we have also assumed that: (i) the ATM Shares will be issued and sold in compliance with federal and state securities laws and in the manner stated in the Registration Statement and the Prospectus Supplement; and (ii) all corporate or other action required to be taken by the Company to duly authorize the issuance of the ATM Shares and the terms of the offering thereof, and any related documentation (including the execution, delivery and performance of the Sales Agreement and ATM Shares, and any related documentation referred to in our opinion set forth below) shall have been duly completed and shall remain in full force and effect.

Based on the foregoing and on such legal considerations as we deem relevant, and subject to the limitations, qualifications, exceptions, and assumptions set forth herein and in reliance on the statements of fact contained in the documents we have examined, we are of the opinion that, when the Sales Agreement shall have been duly executed and delivered by the respective parties thereto, the ATM Shares to be offered and sold by the Company have been duly authorized and, when duly executed, authenticated, delivered, and sold by the Company against payment in full of the consideration for the ATM Shares in accordance with the terms set out in the Prospectus Supplement and the terms in the Sales Agreement, will be validly issued, fully paid and non-assessable.

The opinion expressed herein is limited solely and in all respects to the DGCL and the federal laws of the United States of America that, in our experience, are applicable to transactions of the type contemplated by the Sales Agreement, and we express no opinion as to the laws of any other jurisdiction. We express no opinion as to any matter other than as expressly set forth above, and no other opinion is intended to be implied or inferred herefrom. The opinion expressed herein is given as of the date hereof and we undertake no obligation hereby and disclaim any obligation to advise you of any change in law, facts or circumstances occurring after the date hereof pertaining to any matter referred to herein.

This opinion is provided as a legal opinion only, effective as of the date of this letter, and not as representations of fact. We understand that you have made such independent investigations of the facts as you deemed necessary, and that the determination of the extent of those investigations that are necessary has been made independent of this opinion letter.

We hereby consent to the reference to our firm under the caption "Legal Matters" in the Prospectus Supplement and to the filing of this opinion letter as Exhibit 5.1 to the Company's Current Report on Form 8-K filed on October 17, 2025. In giving this consent, we do not admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
