Item 1.02. Termination of a Material Definitive Agreement.

On July 14, 2026, BETA Technologies, Inc. (the “Company”) received notice from the Defense Counterintelligence and Security Agency (“DCSA”) that the Security Control Agreement (the “SCA”), dated June 15, 2025, by and among QIA Industrials Holding, LLC (“QIA”), the Company, and the U.S. Department of Defense, is no longer required and has been terminated. The SCA was put in place to mitigate foreign ownership, control, or influence considerations arising from QIA’s prior board representation. Because QIA no longer has representation on the Company’s Board of Directors, DCSA determined that the SCA is no longer necessary.
