No observed cheques. Organisations of this type rarely announce deals, so this says nothing about their activity.
From their own site: “ARB invests in later stage growth companies and funds committed to commercializing solutions that accelerate the transition to a sustainable and clean energy economy.”
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.
