No observed cheques. Organisations of this type rarely announce deals, so this says nothing about their activity.
From their own site: “ARM Holdings, LP is a Georgia (USA) limited partnership established in 1997 as a corporate entity for founder Anthony R. Morgenthau (ARM). Mr. Morgenthau is an investment banker and the founder and CEO of Morgenthau & Associates, Inc. (a FINRA Registered Stock Brokerage Firm)”
An announcement gives the size of the round, not the size of this investor's cheque. The only rounds that imply a cheque are those where they were the sole named investor.
