(Headquarters: Shinjuku-ku, Tokyo; Chief Executive Officer: Yoshiyuki Shikura; hereinafter “HIGHRESO”) and AT TOKYO Corporation (Headquarters: Koto-ku, Tokyo; President & Chief Executive Officer: Tatsuya Izumida; hereinafter “AT TOKYO”) have signed a memorandum of understanding to conduct a proof-of-concept (PoC) for validating GPU service business models and interconnectivity.
