Item 8.01. Other Events.

As previously disclosed, on April 29, 2026, Plutonian Acquisition Corp II (the “Company”) consummated its initial public offering (“IPO”), which consisted of 10,000,000 units (the “Units”). Each Unit consists of one Class A ordinary share, $0.0001 par value (“Class A Ordinary Share”) and one right of the Company (each, a “Right”), with each Right entitling the holder to receive one-fourth of a Class A Ordinary Share upon consummation of an initial business combination. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $100,000,000.

The Company granted the underwriters a 45-day option to purchase up to an additional 1,500,000 Units (the “Option Units”) at $10.00 per unit to cover over-allotments, if any. On April 29, 2026, the underwriters notified the Company of their partial exercise of the over-allotment option to purchase 750,000 additional units (the “Option Units”) at $10.00 per unit. The closing of the issuance and sale of the Option Units occurred on May 5, 2026, generating total gross proceeds of $7,500,000. Simultaneously with the closing of the over-allotment option, the Company consummated the private placement of an aggregate of 7,800 Private Placement Units to the Sponsor, at a price of $10.00 per Private Placement Unit, generating gross proceeds of $78,000.

A total of $108,037,500 ($10.05 per Unit) of the net proceeds from the sales of Units in the IPO, the Option Units and the Private Placements on April 29, 2026 and May 5, 2026, were placed in a trust account with Continental Stock Transfer& Trust acting as trustee.

The Private Units were issued pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, as the transactions did not involve a public offering.

An audited balance sheet as of April 29, 2026 reflecting receipt of the proceeds upon consummation of the IPO has been issued by the Company and previously filed as Exhibit 99.1 to a Current Report on Form 8-K on May 5, 2026.

An unaudited pro forma balance sheet as of May 5, 2026, reflecting the consummation of the partial exercise of the underwriters’ over-allotment option and the related transactions, is included as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
