Speaking about the deals, Pattern CEO Mike Garland said: "We are increasing our CAFD [cash available for distribution] per share growth target to 12-15% due to several key factors that give us added confidence in achieving or exceeding our growth objectives. These include today's three acquisitions, advancement of our nearly 1GW in identified ROFO [right of first offer] projects and the expansion of our development pipeline, including visibility to more than 500MW of projects that will be ready to be added to the identified ROFO list over the next 12 months."
