This supplement (this “Supplement”) amends and supplements the definitive proxy statement on Schedule 14A filed by Sunrise Realty Trust, Inc. (the “Company”) with the Securities and Exchange Commission (the “SEC”) on September 18, 2026 (the “Proxy Statement”), relating to the consideration of a proposal to approve the issuance of approximately 8,464,955 shares of the Company’s common stock, $0.01 par value per share (the “Common Stock”), as stock consideration (the “Stock Issuance Proposal”) in the Merger (as defined below) at the Company’s special meeting of stockholders to be held on October 23, 2026 (the “Special Meeting”).

As previously disclosed, on August 5, 2026, the Company, Southern Realty Trust Inc., a Maryland corporation (“SRT”), Sunrise Merger Sub, LLC, a Maryland limited liability company and a wholly owned subsidiary of the Company (“Merger Sub”), and, solely for the limited purposes set forth in the Merger Agreement (as defined below), Sunrise Manager LLC, a Delaware limited liability company and the external manager of the Company, entered into an Agreement and Plan of Merger (the “Merger Agreement”). Under the terms and subject to the conditions set forth in the Merger Agreement, SRT will merge with and into Merger Sub (the “Merger”), with Merger Sub surviving the Merger as a wholly owned subsidiary of the Company.

In connection with the Merger, the Company filed the Proxy Statement with the SEC on September 18, 2026 to seek stockholder approval of the Stock Issuance Proposal and provide disclosure related to the Merger. The Proxy Statement has been mailed to the Company’s stockholders. The Company is filing this Supplement to update and supplement the Proxy Statement.

On September 23, 2026, a purported stockholder of the Company filed a complaint against the Company and the Company’s board of directors (the “Miller Complaint”). The Miller Complaint, captioned Miller v. Sunrise Realty Trust, Inc., et al., Index No 655415/2026 (N.Y. Sup. Ct.), asserts that the Proxy Statement omitted material information in violation of New York common law. Also on September 24, 2026, a purported stockholder of the Company filed a complaint against the Company and the Company’s board of directors (the “Smith Complaint” and, together with the Miller Complaint, the “Complaints”). The Smith Complaint, captioned Smith v. Sunrise Realty Trust, Inc., et al., Index No 655426/2026 (N.Y. Sup. Ct.), similarly asserts that the Proxy Statement omitted material information in violation of New York common law. The Complaints seek, among other things, preliminary and permanent injunctions enjoining consummation of the Merger absent additional disclosures in the Proxy Statement; rescission of the Merger if consummated without the demanded disclosures; damages; and attorneys’ fees and expenses.

In addition, the Company has received demand letters from purported stockholders of the Company, generally alleging omissions or misstatements in the disclosures in the Proxy Statement and requesting that the Company file additional disclosures prior to the Special Meeting (the demand letters are collectively referred to as the “Stockholder Letters”).

While the Company believes that the disclosures in the Proxy Statement comply with all applicable laws and denies the allegations in the Complaints and Stockholder Letters described above and believes they are without merit, in order to moot the allegations, and any potential claims, regarding disclosures, avoid nuisance and possible expense and business delays, and provide additional information to its stockholders, the Company has determined voluntarily to supplement certain disclosures in the Proxy Statement related to the Complaints’ and Stockholder Letters’ allegations with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures should be deemed an admission of the legal merit, necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company specifically denies all allegations in the Complaints and Stockholder Letters that any additional disclosure was or is required or material.

It is possible that additional, similar complaints may be filed, that the Complaints may be amended or that additional demand letters will be received by the Company. If this occurs, the Company does not intend to announce the filing or receipt of each additional, similar complaint or demand letter or any amended complaint unless required by law.

Supplemental Disclosures

The Supplemental Disclosures should be read in conjunction with the Proxy Statement, which should be read in its entirety. Defined terms used in the Supplemental Disclosures that are not defined herein have the meanings set forth in the Proxy Statement. All page references in the Supplemental Disclosures are to pages in the Proxy Statement. Paragraph references in the Supplemental Disclosures refer to paragraphs in the Proxy Statement before any additions or deletions resulting from the Supplemental Disclosures. The information herein speaks only as of October 13, 2026, unless (and then only to the extent) the information indicates another date applies. For clarity, new text within restated portions of the Proxy Statement is indicated by bold typeface and underlining.

On April 27, 2026, SUNS and SRT executed a customary mutual confidentiality agreement in connection with the Potential Transaction, which agreement did not contain a standstill or a “don’t ask, don’t waive” provision. Neither the Company nor SRT entered into confidentiality agreements with any other third parties in connection with the Potential Transaction. Shortly thereafter, the advisors to the Special Committee and SUNS were granted access to certain non-public information concerning SUNS’ and SRT’s businesses and operations in order to facilitate their respective reviews of both companies. Those reviews continued until early August 2026.

On June 20, 2026, the Special Committee sent a revised response to the SRT Board to the Revised IoI (the “SUNS Response”). The SUNS Response reflected agreement on the Agreed Premium but replaced the Post-Signing Adjustment Provision with a provision requiring that the final exchange ratio be calculated based on NBV of each party measured as of the end of the month immediately preceding signing of the merger agreement. The SUNS Response also removed the $1.4 million aggregate cash payment by SUNS Manager to SRT Stockholders and replaced that provision with language providing that SUNS Manager would waive certain fees (in an amount to be determined) for the benefit of all SUNS Stockholders following the closing of the transaction. The SUNS Response also reverted the post-closing board representation provision such that SRT would be entitled to designate one independent director to the SUNS Board at closing. Further, the SUNS Response included a description of the contemplated amendments to the Existing Management Agreement, reducing the incentive fee from 20% to 17.5% and the hurdle rate from 8.0% to 7.0%, which hurdle rate mirrored the term in the existing SRT Management Agreement, as well as proposed changes to the termination fee provisions, including removing the reverse termination fee and setting the termination fees at 2.0% of NBV of SRT (inclusive of the Agreed Premium) if the merger agreement were terminated in order for SRT to enter into a superior proposal prior to the expiration of the go-shop period and 4.0% of the NBV of SRT (inclusive of the Agreed Premium) if the merger agreement were terminated in order for SRT to enter into a superior proposal after the go-shop period ends. In addition, SUNS would be required to pay a termination fee to SRT in an amount equal to 4.0% of the NBV of SUNS if the merger agreement were terminated in order for SUNS to accept a superior proposal; provided that no termination fees would be payable on behalf of either party in the event that both SUNS and SRT were acquired by, or merge with, the same third-party acquiror. Throughout their discussions, the parties did not discuss any changes to the terms or conditions of employment, compensation or incentive pay of any of SUNS’ executive officers, it being understood that the SUNS’ executive officers would remain employed by an affiliate of SUNS Manager following the closing of the Merger.

Following the closing of the Merger and the effectiveness of the A&R Management Agreement, we will continue to have no employees who are compensated directly by the Company. Our current management team will remain in place and will continue to be employed by SUNS Manager and/or its affiliates.

SUNS Dividend Discount Analysis. Oppenheimer performed a dividend discount analysis of SUNS to calculate the estimated present value of the dividends that SUNS was forecasted to pay for the fiscal years ending December 31, 2027 and December 31, 2028, based on the SUNS Projections, assuming a transaction closing date of December 31, 2026. The projected dividends used in the analysis were $18.7 million, or $1.38 per share, for the fiscal year ending December 31, 2027 and $17.9 million, or $1.33 per share, for the fiscal year ending December 31, 2028. Oppenheimer calculated terminal values for SUNS by applying a range of P / NTBV multiples of 0.50x to 1.02x to SUNS’ estimated net tangible book value per share as of December 31, 2028. Oppenheimer then discounted the projected dividends and terminal values to present value using discount rates ranging from 12.3% to 16.3% for SUNS. The discount rate range was based on Oppenheimer’s derived cost of equity for SUNS of 14.3%, plus or minus 2.0%. This analysis indicated the following approximate implied per-share value reference range for SUNS Common Stock:

SRT Dividend Discount Analysis. Oppenheimer performed a dividend discount analysis of SRT to calculate the estimated present value of the dividends that SRT was forecasted to pay for the fiscal years ending December 31, 2027 and December 31, 2028, based on the SRT Projections, assuming a transaction closing date of December 31, 2026. The projected dividends used in the analysis were $11.2 million, or $1.95 per share, for the fiscal year ending December 31, 2027 and $10.2 million, or $1.78 per share, for the fiscal year ending December 31, 2028. Oppenheimer calculated terminal values for SRT by applying a range of P / NTBV multiples of 0.50x to 1.02x to SRT’s estimated net tangible book value per share as of December 31, 2028. Oppenheimer then discounted the projected dividends and terminal values to present value using discount rates ranging from 14.1% to 18.1% for SRT. The discount rate range was based on Oppenheimer’s derived cost of equity for SRT of 16.1%, plus or minus 2.0%. This analysis indicated the following approximate implied per-share value reference range for SRT Common Stock:

Stock Repurchase Program

On October 12, 2026, the Board of Directors (the “Board”) of the Company authorized a stock repurchase program (the “Repurchase Program”), pursuant to which the Company is authorized to repurchase up to $20.0 million of shares of its outstanding Common Stock through December 31, 2027. The Repurchase Program will not be effective until the closing of the Merger, and the Company will not make any repurchases under the Repurchase Program prior to the closing of the Merger.

Following the closing of the Merger, the Company currently intends to repurchase at least $10.0 million of its outstanding Common Stock as soon as practicable, with the remaining $10.0 million subject to specified pricing and other parameters. In each case, the Company expects the repurchases will be made through a written trading plan in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and subject to certain daily volume limitations and other conditions set forth therein and in accordance with Rule 10b-18 under the Exchange Act. The Company is not obligated to repurchase any specific number of shares or dollar amount, and the program may be modified, suspended or terminated at any time without prior notice. The timing and extent to which the Company repurchases its outstanding Common Stock will depend upon, among other things, market conditions, share price, liquidity, regulatory requirements and other factors, and repurchases may be commenced or suspended at any time without prior notice. Acquisitions under the Repurchase Program may be made in the open market, through privately negotiated transactions or block trades or other means, in accordance with applicable securities laws.

The Company announced the Repurchase Program in a Current Report on Form 8-K filed with the SEC on October 13, 2026.
