On February 21, 2025 (the “Closing Date”), Inhibikase Therapeutics, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with Project IKT Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“Merger Sub”), CorHepta Pharmaceuticals, Inc., a Delaware corporation (“CorHepta”), and Preston S. Klassen, solely in his capacity as sellers’ representative.

Pursuant to the Merger Agreement, on the Closing Date, Merger Sub merged with and into CorHepta (the “Merger”), with CorHepta surviving the Merger as a wholly-owned subsidiary of the Company. On the Closing Date, the Company paid consideration for CorHepta of $15.0 million, subject to a customary purchase price adjustment mechanism. The Company paid the purchase price pursuant to the issuance of an aggregate of 4,979,101 shares (the “Consideration Shares”) of the Company’s common stock, par value $0.001 per share (“Common Stock”), to the former stockholders of CorHepta (the “CorHepta Stockholders”), of which 3,319,397 were issued as upfront consideration (“Upfront Consideration”). 82,979 Consideration Shares of the Upfront Consideration were deposited in a twelve-month escrow for purposes of satisfying potential indemnity obligations of the CorHepta Stockholders under the Merger Agreement. The remaining Consideration Shares were issued as contingent consideration (“Contingent Consideration”), which will vest upon achievement of a certain milestone. If the vesting condition is not satisfied as of the first anniversary of the Closing Date, then the Contingent Consideration will be forfeited.

The foregoing description of each of the Merger Agreement is only a summary and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which will be filed with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and is incorporated by reference.

The foregoing summary of the Merger Agreement has been included to provide securityholders with information regarding its terms. It is not intended to provide any other factual information about the Company, CorHepta or any other party thereto. The representations, warranties and covenants contained in the Merger Agreement were made solely for purposes of such agreement and as of specific dates, are solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purpose of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to securityholders. Securityholders should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company, CorHepta or any other party thereto. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures, except to the extent required by law.
