TOKYO, Sept. 21, 2026 /PRNewswire/ -- TOYO Co., Ltd. (Nasdaq: TOYO) (OTC: TOYWF) ("TOYO" or the "Company"), a solar manufacturing company, today announced that its module manufacturing facility in Humble, Texas achieved a strong result in a comprehensive, independent factory audit conducted by Intertek CEA in August 2026.

The audit, performed by Intertek CEA — a leading independent quality assurance and supply chain risk provider to the solar industry — evaluated TOYO's Texas facility across a broad range of criteria, including certifications, employee management, incoming material handling, production process controls, and finished product quality systems. The assessment covered the facility's systems and conditions at that time and does not constitute a product certification or a guarantee of future production quality.

"This independent assessment reflects the discipline our team has built into every stage of module production at our Texas facility, from incoming material handling through final packaging," said Takahiko Onozuka, Chairman and CEO of TOYO. "The facility's strong performance in this independent assessment reflects our commitment to quality as we scale U.S. manufacturing capacity."

TOYO's Humble, Texas facility is a key part of the Company's U.S. manufacturing platform, supporting its module production capacity as the Company continues to scale toward its planned 2 GW of U.S. module capacity.
