Item 8.01. Other Events.

As previously disclosed, on May 21, 2025, Star Equity Holdings, Inc., a Delaware corporation (“Star”), Hudson Global, Inc., a Delaware corporation (“Hudson”), and HSON Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Hudson (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Star, with Star continuing as the surviving corporation of the merger (the “Merger”), and a wholly owned subsidiary of Hudson.

Subject to the terms and conditions of the Merger Agreement, upon the closing of the Merger and the other transactions contemplated by the Merger Agreement (the “Closing”), (a) any shares of Star common stock held as treasury stock or held directly by Hudson or Merger Sub (or any of their respective subsidiaries) will be canceled, retired and cease to exist, and no consideration shall be delivered in exchange therefor, (b) each then-outstanding share of Star common stock will be converted into the right to receive 0.23 shares of Hudson common stock calculated in accordance with the terms of the Merger Agreement (the “Exchange Ratio”), (c) each then-outstanding share of Star Series A preferred stock will be converted into the right to receive one (1) share of Hudson Series A preferred stock (the “Hudson Series A Preferred Stock”) in accordance with the terms of the Merger Agreement, and (d) each then-outstanding option to purchase Star common stock or restricted stock units issued by Star will be converted into an option to purchase Hudson common stock or a restricted stock unit of Hudson, as applicable, which shall entitle the holder thereof to receive shares of Hudson common stock once such options are exercised or such restricted stock units are fully vested, as applicable, in each case in such amounts and on such terms as set forth in the Merger Agreement.

In connection with the Merger, Star agreed to call a special meeting of the holders of Star common stock to seek the approval of stockholders of the Merger Agreement and the consummation of the Merger (the “Special Meeting”). The board of directors of Star has set the date and time of the Special Meeting for 10:00 a.m. Eastern Time on August 21, 2025, to be held in person at 53 Forest Avenue, Suite 101 Old Greenwich, CT 06870.

In furtherance thereof, pursuant to the Merger Agreement, Hudson has filed a registration statement on Form S-4 (the “Registration Statement”) to register the shares of Hudson common stock and Hudson Series A Preferred Stock issuable pursuant to the Merger Agreement, which Registration Statement includes a joint proxy statement/prospectus of Star and Hudson (the “Proxy Statement/Prospectus”) forming a part thereof and giving notice to Star stockholders of the calling of the Special Meeting. On July 22, 2025, the Registration Statement was declared effective by the United States Securities and Exchange Commission (the “SEC”). Star will begin promptly disseminating the Proxy Statement/Prospectus to stockholders by mail. The Proxy Statement/Prospectus contains additional information regarding the Special Meeting, including the full list of proposals to be voted upon and instructions for stockholders regarding how to vote their shares and participate in the Special Meeting.

The parties have determined that (i) the exchange of a U.S. Star stockholder’s shares of Star common stock for shares of Hudson common stock and (ii) the exchange of a U.S. Star stockholder’s shares of Star Series A preferred stock for shares of Hudson Series A Preferred Stock in the Merger will each be taxable transactions for U.S. federal income tax purposes. For additional details, stockholders should consult the section of the Proxy Statement/Prospectus titled “The Merger—Material U.S. Federal Income Tax Considerations of the Merger”.

Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, including but not limited to, express or implied statements regarding the structure, timing and completion of the

proposed Merger; the combined company’s listing on Nasdaq after closing of the proposed Merger; expectations regarding the ownership structure of the combined company; and other statements that are not historical fact. All statements other than statements of historical fact contained in this Current Report on Form 8-K are forward-looking statements. These forward-looking statements are made as of the date they were first issued, and were based on the then-current expectations, estimates, forecasts, and projections, as well as the beliefs and assumptions of management. There can be no assurance that future developments affecting Star, Hudson, or the proposed transaction will be those that have been anticipated.

Forward-looking statements are subject to a number of risks and uncertainties, many of which involve factors or circumstances that are beyond Star’s control. Star’s actual results could differ materially from those stated or implied in forward-looking statements due to a number of factors, including but not limited to (i) the risk that the conditions to the closing of the proposed Merger are not satisfied, including the failure to timely obtain stockholder approval for the transaction, if at all; (ii) uncertainties as to the timing of the consummation of the proposed Merger and the ability of each of Star and Hudson to consummate the proposed Merger; (iii) risks related to Star’s ability to manage its operating expenses and its expenses associated with the proposed Merger pending closing; (iv) risks related to the failure or delay in obtaining required approvals from any governmental or quasi-governmental entity necessary to consummate the proposed Merger; (v) risks related to the market price of Star’s common stock relative to the value suggested by the exchange ratio; (vi) unexpected costs, charges or expenses resulting from the transaction; (vii) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed Merger; (viii) risks related to the inability of the combined company to successfully operate as a combined business; and (ix) risks associated with the possible failure to realize certain anticipated benefits of the proposed Merger, including with respect to future financial and operating results, among others. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties. These and other risks and uncertainties are more fully described in periodic filings with the SEC, including the factors described in the section titled “Risk Factors” in Star’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC, and in other filings that Star makes and will make with the SEC in connection with the proposed Merger, including the Proxy Statement/Prospectus. You should not place undue reliance on these forward-looking statements, which are made only as of the date hereof or as of the dates indicated in the forward-looking statements. Star expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in its expectations with regard thereto or any change in events, conditions or circumstances on which any such statements are based. This Current Report on Form 8-K does not purport to summarize all of the conditions, risks and other attributes of an investment in Star or Hudson.
