Earnings drivers year-over-year for the third quarter 2017 were positively influenced by retail revenue effects at Southern Company’s traditional electric operating companies and were negatively influenced by mild weather, timing for Southern Power tax credits, increased interest expense and share issuances.

“Our premier, state-regulated electric and gas franchise operations and our competitive generation subsidiary, Southern Power, continued to perform at a high level in the third quarter of 2017, delivering on our commitment to provide clean, safe, reliable and affordable energy to customers,” said Chairman, President and CEO Thomas A. Fanning. “This longstanding customer focus, as further manifested by the resiliency demonstrated in our hurricane restoration efforts during the past quarter, is the cornerstone for delivering on our long-term financial objectives as we continue to build America’s energy future.”

Third quarter 2017 operating revenues were $6.20 billion, compared with $6.26 billion for the third quarter of 2016, a decrease of 1.0 percent. This decrease in quarter-over-quarter revenues is primarily due to the effects of milder weather and electricity outages experienced during Hurricane Irma. For the nine months ended September 30, 2017, operating revenues were $17.4 billion, compared with $14.7 billion during the same period of 2016, an increase of 18.3 percent. Southern Company Gas accounted for $2.3 billion of the increase in operating revenues for the nine months ended September 30, 2017.

Southern Company’s third quarter earnings slides with supplemental financial information are available at http://investor.southerncompany.com.

Southern Company’s financial analyst call will begin at 1 p.m. Eastern Time today, during which Fanning and Chief Financial Officer Art P. Beattie will discuss earnings and provide a general business update. Investors, media and the public may listen to a live webcast of the call and view associated slides at http://investor.southerncompany.com/webcasts. A replay of the webcast will be available on the site for 12 months.

Financial Highlights

Notes

- In connection with the adoption in the fourth quarter 2016 of a new accounting standard for stock compensation, previously reported amounts for income tax expense were reduced by a total of $9 million and $25 million for the three and nine months ended September 30, 2016, respectively.

- For comparative purposes, Net Income - Excluding Items and Basic Earnings Per Share - Excluding Items in prior year periods do not reflect any adjustments to exclude (1) Southern Company Gas earnings, net of acquisition and integration costs and Wholesale Gas Services ($0.04 per share for the three and nine months ended September 30, 2016), (2) acquisition debt financing costs related to the acquisition of Southern Company Gas ($0.05 and $0.07 per share for the three and nine months ended September 30, 2016, respectively), and (3) the impact of additional shares of common stock issued to finance a portion of the purchase price for the 50% interest in Southern Natural Gas Company, L.L.C. (SNG) ($0.02 and $0.01 per share for the three and nine months ended September 30, 2016, respectively). These items were not contemplated in Southern Company's February 2016 guidance and, therefore, were previously excluded in the periods through December 31, 2016.

(1) On July 1, 2016, Southern Company completed the acquisition of Southern Company Gas.

(2) For the three and nine months ended September 30, 2017 and 2016, dilution does not change basic earnings per share by more than 2 cents and is not material.

(3) Earnings for the three and nine months ended September 30, 2017 and 2016 include the estimated losses relating to Mississippi Power Company's integrated coal gasification combined cycle facility construction project in Kemper County, Mississippi (Kemper IGCC) which significantly impacted the presentation of earnings and earnings per share. Further charges of uncertain amounts may occur in future periods in connection with the resolution of the Mississippi Public Service Commission's Kemper Settlement Docket.

(4) Earnings for the nine months ended September 30, 2017 include a $32.5 million write-down ($20 million after tax) of Gulf Power Company's ownership of Plant Scherer Unit 3 as a result of the retail rate case settlement approved by the Florida Public Service Commission on April 4, 2017. Further charges are not expected to occur.

(5) Earnings for the three and nine months ended September 30, 2017 and 2016 include costs related to the acquisition and integration of Southern Company Gas. Further costs are expected to continue to occur in connection with the related integration activities; however, the amount and duration of such expenditures is uncertain.

(6) Earnings for the three and nine months ended September 30, 2017 and 2016 include the Wholesale Gas Services business of Southern Company Gas. Presenting earnings and earnings per share excluding Wholesale Gas Services provides investors with an additional measure of operating performance that excludes the volatility resulting from mark-to-market and lower of weighted average cost or current market price accounting adjustments.

(7) Earnings for the nine months ended September 30, 2017 and the three and nine months ended September 30, 2016 include additional allowance for funds used during construction (AFUDC) equity as a result of extending the schedule for the Kemper IGCC construction project. AFUDC equity ceased in connection with the project's suspension in June 2017. Southern Company's 2017 earnings guidance, initially presented in October 2016, assumed construction would be complete and AFUDC equity would cease by November 30, 2016. Southern Company's 2016 earnings guidance, initially presented in February 2016, assumed construction would be complete and AFUDC equity would cease by August 31, 2016. As a result, Southern Company believes presentation of earnings per share excluding AFUDC equity subsequent to August 31, 2016 provides investors with information comparable to guidance. Management also uses such measures to evaluate Southern Company's performance.
