Item 1.01. Entry into a Material Definitive Agreement.

On April 29, 2026, Irenic Acquisition Corp. (the “Company”) consummated its initial public offering (“IPO”) of 22,000,000 units (the “Units”). Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Ordinary Shares”), and one-third of one redeemable warrant (the “Warrants”). The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $220,000,000. The Company has granted the underwriters a 45-day option to purchase up to an additional 3,300,000 Units at the initial public offering price to cover over-allotments, if any.

In connection with the IPO, the Company entered into the following agreements, forms of which were previously filed as exhibits to the Company’s Registration Statement on Form S-1 (File No. 333-294983) for the IPO, initially filed with the U.S. Securities and Exchange Commission (the “Commission”) on April 10, 2026, as amended (the “Registration Statement”):

Item 3.02. Unregistered Sales of Equity Securities.

Simultaneously with the closing of the IPO, pursuant to the Private Placement Units Purchase Agreements, the Company completed the private sale of 640,000 units (the “Private Placement Units”) at the initial public offering price of $10.00 per unit (for an aggregate purchase price of $6,400,000). Of those 640,000 Private Placement Units, the Sponsor purchased 420,000 Private Placement Units and Jefferies LLC and Odeon Capital Group LLC purchased an aggregate of 220,000 Private Placement Units. Each Private Placement Unit consists of one Class A ordinary share and one-third of one warrant. The Private Placement Units are identical to the Units sold in the IPO, except as otherwise disclosed in the Registration Statement. No underwriting discounts or commissions were paid with respect to such sale. The issuance of the Private Placement Units was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.
