The company highlights a transformative settlement with Puerto Rico Electric Power Authority giving subsidiary Cobra an allowed administrative expense claim of $170.0 million plus $18.4 million of previously withheld FEMA funds, with a first installment of $150.0 million received in October 2024 and a subsequent $18.4 million payment later that month.
