As previously disclosed, on December 5, 2025, Crawford United Corporation, an Ohio corporation (which we refer to as “Crawford United,” the “Company,” “we,” “us” and “our”), entered into an Agreement and Plan of Merger (as it may be amended from time to time, which we refer to as the “Merger Agreement”) with SPX Enterprises, LLC, a Delaware limited liability company (which we refer to as “Parent” or “SPX”), and Project King Acquisition, Inc., an Ohio corporation and a wholly owned subsidiary of Parent (which we refer to as “Merger Sub”). The Merger Agreement provides that, on the terms and subject to the conditions of the Merger Agreement, Merger Sub will merge with and into Crawford United (which we refer to as the “Merger”), with Crawford United continuing as the surviving corporation in the Merger and as a wholly owned subsidiary of Parent.

On January 5, 2026, Crawford United filed its definitive proxy statement on Schedule 14A (as it may be supplemented from time to time, which we refer to as the “Definitive Proxy Statement”) with the Securities and Exchange Commission (the “SEC”) with respect to Crawford United’s special meeting of shareholders (including any adjournments or postponements thereof, which we refer to as the “Special Meeting”) to be held in connection with transactions contemplated by the Merger Agreement. The Special Meeting is scheduled to be held on February 3, 2026, at 10:00 a.m. Eastern Time.

Litigation Regarding the Merger

On January 14, 2026 and January 15, 2026, two purported Crawford United shareholders each filed separate complaints in the New York Supreme Court, New York County against Crawford United and the members of the Crawford United board of directors (which we refer to as the “Board”), which are captioned Steven Carter v. Crawford United Corporation, et al. (No. 650250/2026) (the “Carter Complaint”) and John Clark v. Crawford United Corporation, et al. (No. 650281/2026) (the “Clark Complaint” and, together with the Carter Complaint, the “Complaints”). Additionally, Crawford United has received separate demand letters (which we refer to as the “Shareholder Letters,” and together with the Complaints, the “Shareholder Matters”) from purported shareholders of Crawford United. Each of the Shareholder Matters allege that, among other things, the Definitive Proxy Statement contains certain disclosure deficiencies and/or incomplete information regarding the Merger. The Complaints further purport to seek (i) to enjoin the consummation of the Merger until such time as the allegedly omitted material information has been disclosed, or (ii) rescind the Merger or obtain an award of money damages if the Merger has been consummated.

Crawford United believes that the allegations in the Shareholder Matters are without merit. Additional lawsuits or demands arising out of the Merger may be filed or made in the future and, if this occurs, Crawford United will not necessarily announce them. Crawford United cannot assure you as to the outcome of the Shareholder Matters or any such additional lawsuits or demands.

Crawford United believes that no further disclosure is required under applicable laws beyond that already contained in the Definitive Proxy Statement. However, in order to avoid the risk that the Shareholder Matters delay or otherwise adversely affect the completion of the Merger, and to minimize or avoid any further nuisance, costs, distraction, risks and uncertainties, and without admitting any culpability, liability or wrongdoing and without admitting the relevance or materiality of such disclosures, and reserving all rights to contest the substantive allegations in the Shareholder Matters, and the jurisdiction of courts in which the Complaints were filed, Crawford United is voluntarily supplementing the Definitive Proxy Statement with the disclosures set forth below under the heading “Supplementary Disclosures.” Nothing in such supplementary disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Crawford United specifically denies all allegations in the Complaints and Shareholder Letters, including that any additional disclosure was or is required.

All paragraph headings and page references used herein refer to the headings and pages in the Definitive Proxy Statement before any additions or deletions resulting from the supplementary disclosures set forth herein or any other amendments or supplements, and certain capitalized terms used below, unless otherwise defined, have the meanings set forth in the Definitive Proxy Statement. The supplemental information is identified below by bold underlined text. Stricken-through text shows text being deleted from a referenced disclosure in the Definitive Proxy Statement. Except as described herein, the information provided in the Definitive Proxy Statement continues to apply. To the extent that information herein differs from or conflicts with information contained in the Definitive Proxy Statement, the information set forth herein shall supersede or supplement the information in the Definitive Proxy Statement.
