Merlyn Global Group is a company that was owned and run by the Merlyn family. It was one of the prime businesses in Star City. In the wake of the Undertaking, there has been no further mention of the company.
Merlyn Global Group sponsored a fundraiser for
CNRI when their largest donor, Stagg Industries, pulled out.
The company helped to create the
Markov Device that caused the Undertaking, resulting in the death of 503 people, including Malcolm's son, Tommy Merlyn.
With Malcom's role in the Undertaking revealed to the public,
it is unknown if Merlyn Global Group is still operational.
alternate reality created by the Dominators, the company still existed in Star City and Malcolm was presumably the CEO.
rewritten reality created by the Legion of Doom using the Spear of Destiny, Malcolm was still the well-respected CEO of Merlyn Global Group.
DC's Legends of Tomorrow
Presumably, as Malcolm's daughter, Thea Queen could stake some kind of claim to his shares in this enterprise.
