TRADEMARK ACQUISITION AND LICENSE

As previously reported, on September 4, 2025, each of TOYO Co., Ltd, a Cayman Islands exempted company (the “Company”) and Toyo Solar Company Limited, a Vietnamese company and wholly-owned subsidiary of the Company (“TOYO Solar” and, together with the Company, the “TOYO Group”), entered into a trademark purchase agreement (each, a “Trademark Purchase Agreement”) with Vietnam Sunergy Europe GmbH, a German company and subsidiary of VSUN (as defined below) (“VSUN Europe”), and Vietnam Sunergy Joint Stock Company (“VSUN” and, together with VSUN Europe, “VSUN Group”), a Vietnamese company and our affiliate and a majority-owned subsidiary of Fuji Solar Co., Ltd, a Japanese company. Pursuant to the Trademark Purchase Agreements, VSUN Group agreed to sell to the TOYO Group its “VSUN” trademarks (the “Subject Trademarks”) registered in 12 jurisdictions, including but not limited to, the United States, Canada, Vietnam and Europe, for a total purchase price of $340,000 (such transaction, the “Trademark Acquisition”).

In connection with and upon the completion of the Trademark Acquisition, on September 12, 2025, each of the Company and TOYO Solar entered into a trademark license agreement with VSUN (each, a “Trademark License Agreement”), pursuant to which the TOYO Group agreed to grant to VSUN a license for VSUN and its subsidiaries and affiliates to use the Subject Trademarks for one (1) year in connection with VSUN’s business purposes, including but not limited to, the manufacturing, promotion, advertising, distribution and sales (the “Trademark License”).

On September 1, 2026, each of the Company and TOYO Solar entered into an amendment to its respective Trademark License Agreement with VSUN (each, an “Amendment”), effective as of September 12, 2026. Pursuant to the Amendments, the parties agreed to extend the term of each Trademark License Agreement from one (1) year to three (3) years. The Amendments also provide that, commencing after September 12, 2026, the license grant will not include rights to use the Subject Trademarks in the United States of America, and the term “Territory” will not be construed to include the United States of America.

Copies of the Amendments are being furnished as Exhibits 99.1 and 99.2 to this Report on Form 6-K. The foregoing descriptions of the Amendments do not purport to be complete and are subject to, and are qualified in their entirety by, the full text of the Amendments.
