ACSL Ltd. (ACSL) hereby announces that ACSL, Inc., our U.S. subsidiary, has signed a Memorandumof Understanding (MOU) with Missouri-based Ameren Corporation（Ameren）, in January 26, 2024, for a
strategic partnership to facilitating the further adoption and use of drone technology in critical infrastructureindustries in the U.S. market.
■Reason and details of the MOU
Policies related to economic security and environmental considerations are accelerating in the global
drone market. In the U.S., the National Defense Authorization Act (NDAA) has been enforced, prohibiting
government procurement of Russian and Chinese drones. In addition, DJI, Chinese drone manufacturer,
has been designated by the U.S. Department of Defense as a "China Military Enterprise" from October
2022. In this market environment, ACSL believes that it is possible to formulate a positioning based on thekeywords "economic security", "enterprise support", and "application-specific".
Against this background, ACSL established a U.S. subsidiary,ACSL, Inc. in California in January 2023 to meet the growing
demand for secure, versatile, and high-performance small aerial
drones, and in December, ACSL, Inc. delivered 50 SOTEN
