Merger Agreement [Abstract] |
MERGER AGREEMENT | 10. MERGER AGRFEEMENT On October 23, 2023, the Company and its then wholly owned subsidiary Citius Oncology entered into an agreement and plan of merger and reorganization (the “Merger Agreement”) with TenX Keane Acquisition, a Cayman Islands exempted company (“TenX”), and TenX Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of TenX (“Merger Sub”). On August 12, 2024, pursuant to the terms and conditions of the Merger Agreement, Merger Sub merged with and into Citius Oncology, with Citius Oncology surviving as a wholly owned subsidiary of TenX (the “Merger”) which was subsequently renamed Citius Oncology Sub. Prior to the closing of the Merger, TenX migrated to and domesticated as a Delaware corporation in accordance with Section 388 of the General Corporation Law of the State of Delaware and the Cayman Islands Companies Act (As Revised) (the “Domestication”). As part of the Domestication, TenX changed its name to “Citius Oncology, Inc.” (Nasdaq: CTOR). Immediately after the closing of the Merger, Citius Pharma owned approximately 92.3% of the outstanding shares of common stock of Citius Oncology. The Merger, net amount of $3,831,357 charged to additional paid in capital consists of $395,515 of net liabilities of TenX on the date of the Merger (cash of $163,500 less liabilities of $559,015) plus directly related transaction costs $2,358,780 and the cost of public rights in the amount of $1,077,062. As part of the Merger, we made capital investments in Citius Oncology through cash contributions of $3,827,944 to fund transactions related to the Merger and by reclassifying to additional paid in capital intercompany receivables of $33,180,961 that were due from Citius Oncology to us. Simultaneously, we advanced an additional $3,800,111 to Citius Oncology under the terms of a non-interest bearing note payable. The note is repayable upon a capital raise by Citius Oncology of at least $10,000,000 through the issuance of debt, equity or royalty financing. The Merger resulted in an initial 92.3% ownership interest by Citius Pharma in Citius Oncology.
