Irma hit southwestern Florida on Sept. 10 as a Category 4 hurricane, leaving millions of Americans without power. The company has about 1.8 million customers in the state.
Duke Energy, which had previously forecast 2017 adjusted earnings of $4.50 to $4.70 per share, shaved the upper end by 10 cents on Friday.
Total operating revenue slipped 1.5 percent to $6.48 billion.
Net income attributable to Duke Energy fell to $954 million, or $1.36 per share, in the quarter ended Sept. 30 from $1.18 billion, or $1.44 per share, a year earlier. (Reporting by Yashaswini Swamynathan in Bengaluru; Editing by Anil D'Silva)
