GameCo said the company “will be appointing a new CEO in due course.” CFO Art Hamilton and head of global business development Rich Maryyanek are filling in the leadership role for the time being.
Graboyes’ departure from GameCo comes less than a week after the NGC voted 4-1 to deny a one-year limited license. The Nevada Gaming Control Board had previously recommended Graboyes received the limited license.
Graboyes was seeking an extended license upon expiration of a temporary license granted two years ago.
In rejecting his application, members of the Commission pointed to his previous experience as CEO of Ohio-based Beyond Gaming, where he was accused of misappropriating intellectual property and engineering bankruptcy.
Another employee of Beyond Gaming previously testified allegations against Graboyes in front of the NGCB.
Graboyes denied the allegations but has yet to announce whether he will appeal the ruling.
Graboyes joined GameCo in 2015. The company offers video game gambling, which combine skill-based video games with real-money casino gambling. GameCo operates games in Oklahoma and Nevada.
