NOTE: For more information regarding these non-GAAP adjustments, see the footnotes accompanying the Financial Highlights page of the earnings package.

Earnings drivers year-over-year for the first quarter of 2018 were positively influenced by revenue effects primarily driven by weather at our state-regulated electric utilities and by infrastructure investments at Southern Company Gas, as well as the optimization of Southern Power’s state tax positions. These impacts were partially offset by increased depreciation and amortization.

“Each of our major business units had a tremendous start to the year,” said Chairman, President and CEO Thomas A. Fanning. “Our premier, state-regulated electric and gas utilities, as well as our other businesses, have performed exceptionally well and are on track to deliver on their targets for 2018.”

First quarter 2018 operating revenues were $6.37 billion, compared with $5.77 billion for the first quarter of 2017, an increase of 10.4 percent.
