Item 8.01. Other Events.

On July 2, 2025, Indigo Acquisition Corp (the “Company”), a Cayman Islands exempt company and special purpose acquisition company, consummated its initial public offering (the “IPO”) of 10,000,000 units (“Units”). Each Unit consists of one ordinary share of the Company, par value $0.0001 per share (“Ordinary Shares”), and one right (“Rights”), each Right entitling its holder to receive one tenth of one Ordinary Share upon the completion of the Company’s initial business combination. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $100,000,000.

Simultaneously with the consummation of the IPO, the Company consummated a private placement (the “Private Placements”) of 350,000 units (“Private Placement Units”), at a price of $10.00 per Private Placement Unit, generating total proceeds of $3,500,000. The Private Placement Units were purchased by the Company’s sponsor, Indigo Sponsor Group, LLC, EarlyBirdCapital, Inc., the representative of the underwriters in the IPO, and certain of their designees. The Private Placement Units are identical to the Units sold in the IPO. The purchasers of the Private Placement Units have agreed not to transfer, assign or sell any of the Private Placement Units or Ordinary Shares or Rights underlying the Private Placement Units, subject to certain customary exceptions, until the completion of the Company’s initial business combination. 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.

An audited balance sheet as of July 2, 2025, reflecting receipt of the proceeds received by the Company in connection with the consummation of the IPO and the Private Placement, has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
