Item 8.01. Other Events.

On January 7, 2026, Art Technology Acquisition Corp. (the “Company”) consummated the sale of 22,000,000 units (the “Units”) in its initial public offering (the “IPO”). The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $220,000,000. 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-fourth of one redeemable warrant of the Company (each, a “Warrant”), with each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share, subject to adjustment as provided in the Company’s registration statement on Form S-1, initially filed with the Securities and Exchange Commission on December 5, 2025 (File No. 333-291966). 

On January 7, 2026, simultaneously with the consummation of the IPO, the Company consummated the issuance and sale (“Private Placement”) of 825,000 Units (the “Placement Units”) in a private placement transaction at a price of $10.00 per Placement Unit, generating gross proceeds of $8,250,000. The Placement Units were purchased by Clear Street, the sole book-running manager for the IPO (295,000 Units) and the Company’s sponsor, Art Technology Sponsor, LLC (530,000 Units).

A total of $220,000,000 of the net proceeds from the IPO and the Private Placement (which includes $8,800,000 of the Underwriters’ deferred discount) were placed in a trust account established for the benefit of the Company’s public shareholders, with Continental Stock Transfer & Trust Company acting as trustee.

An audited balance sheet as of January 7, 2026 reflecting receipt of the proceeds upon 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.
