K Wave Media Ltd. Changes Corporate Name to Nexus Advanced Technologies Inc. and Nasdaq Ticker Symbol to “NXAT”

On September 8, 2026, K Wave Media Ltd. (the “Company”) announced that it has changed its corporate name to Nexus Advanced Technologies Inc., reflecting the Company’s strategic transformation and expanded focus on artificial intelligence infrastructure and advanced technology opportunities. In connection with the name change, the Company’s ordinary shares will begin trading on The Nasdaq Stock Market under the new ticker symbol “NXAT” and its warrant symbol is changing from “KWMWW” to “NXATWW,” effective at market open on September 9, 2026. The Company’s previous ticker symbol was “KWM.”

The name and ticker symbol changes do not affect the rights of the Company’s shareholders. Existing shareholders are not required to take any action in connection with these changes. The corporate name change was authorized by the Company’s shareholders at the Company’s 2026 Annual General Meeting.

The rebranding follows the Company’s previously announced strategic transformation toward AI infrastructure and related technologies, including potential investments and strategic opportunities involving data centers, AI compute resources, GPU infrastructure and other technologies supporting the rapidly expanding global AI ecosystem. On September 8, 2026, the Company issued a press release announcing the corporate name change. A copy of the press release is furnished as Exhibit 99.1 to this current report.
