Entry into a Securities Purchase Agreement

On September 28, 2026, Atlas Trinity Tech Limited, a British Virgin Islands business company (the “Company”), entered into a securities purchase agreement (the “Securities Purchase Agreement”) with 15 purchasers named therein (the “Purchasers”), pursuant to which the Company agreed to issue and sell, and the Purchasers agreed to purchase, an aggregate of 11,750,072 ordinary shares of the Company, par value US$0.0001 per share (the “Shares”), at a purchase price of US$1.27 per Share, for aggregate gross proceeds of US$14,922,591.44 (the “Private Placement”). The closing of the Private Placement is subject to the satisfaction or waiver of the closing conditions set forth in the Securities Purchase Agreement. The Company intends to use the net proceeds from the Private Placement for general corporate purposes.

Pursuant to the Securities Purchase Agreement, the Purchasers have agreed to certain restrictions on the transfer, sale, pledge and hedging of the Shares for a period of 60 days following the closing of the Private Placement, subject to specified exceptions and the Company’s prior written consent. The Company has also agreed to use commercially reasonable efforts to file a registration statement on Form F-1 or Form F-3 with the U.S. Securities and Exchange Commission to register the resale of the Shares as promptly as reasonably practicable after closing, but no later than 60 days following closing, subject to the conditions, exceptions and deferral rights set forth in the Securities Purchase Agreement.

The Securities Purchase Agreement contains customary representations, warranties, covenants and closing conditions. If the closing has not occurred on or before the fifth trading day following the date of the Securities Purchase Agreement, the Company or any Purchaser may terminate the Securities Purchase Agreement with respect to such Purchaser’s obligations by written notice, without affecting the obligations between the Company and the other Purchasers.

The Shares are being offered and sold to non-U.S. persons in offshore transactions in reliance upon Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The Shares have not been registered under the Securities Act or applicable state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements.

The foregoing description of the Securities Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Securities Purchase Agreement, a copy of which is filed as Exhibit 10.1 to this Report on Form 6-K and incorporated herein by reference.

Incorporation by Reference
