On June 12, 2025, the registration statement (File No. 333-286237) (the “Registration Statement”) relating to the initial public offering (“IPO”) of BEST SPAC I Acquisition Corp. (the “Company”) was declared effective by the Securities and Exchange Commission. In connection therewith, the Company entered into the following agreements previously filed as exhibits to the Registration Statement:

● Underwriting Agreement, dated June 12, 2025, by and between the Company and Maxim Group LLC;

● Rights Agreement, dated June 12, 2025, by and between the Company and Continental Stock Transfer & Trust Company;

● Letter Agreement, dated June 12, 2025, by and between the Company’s officers, directors, Maxim Partners LLC and BEST SPAC I (Holdings) Corp.;

On June 16, 2025, the Company consummated the IPO of 5,500,000 units (the “Units”). Each Unit consists of one Class A ordinary share (“Ordinary Share”) and one right (“Right”) to receive one-tenth of one Ordinary Share upon the consummation of an initial business combination. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $55,000,000.

As of June 16, 2025, a total of $55,000,000 of the net proceeds from the IPO and the Private Placement (as defined below) were deposited in a trust account established for the benefit of the Company’s public shareholders. An audited balance sheet as of June 16, 2025 reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement will be filed within four (4) business days of the consummation of the IPO.

Item 3.02. Unregistered Sales of Equity Securities.

Simultaneously with the closing of the IPO, the Company consummated the private placement (“Private Placement”) with BEST SPAC I (Holdings) Corp., the Company’s sponsor (the “Sponsor”), of 277,000 private units (the “Private Units”) at a price of $10.00 per Private Unit, generating total proceeds of $2,770,000.

The Private Units are identical to the Units sold in the IPO. Additionally, the Sponsor agreed not to transfer, assign or sell any of the Private Units or underlying securities (except in limited circumstances, as described in the Registration Statement) until the completion of the Company’s initial business combination. The Sponsor was granted certain demand and piggyback registration rights in connection with the purchase of the Private Units.

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.
