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 second quarter of 2021, as compared with 2020, were strong customer usage, as well as robust customer growth and constructive state regulatory actions. These



impacts were partially offset by higher non-fuel operations and maintenance costs as the emerging economic recovery resulted in a return to more normal business operations. Earnings for the second quarter of 2021 were also significantly impacted by a $343 million after-tax charge related to Georgia Power’s construction of Plant Vogtle units 3 and 4.

“The Southern Company system achieved solid operational performance in the second quarter of 2021,” said Chairman, President and CEO, Thomas A. Fanning. “We saw a year-over-year increase in retail electric sales, as the economies in our service territories continue to recover from the effects of the COVID-19 pandemic, and we experienced strong customer growth in our Southeastern footprint”.

“We’re also pleased to report that the integrated operation of Plant Vogtle Unit 3 has now been demonstrated with the successful completion of hot functional testing, our most significant project milestone to date,” added Fanning.

Second-quarter 2021 operating revenues were $5.2 billion, compared with $4.6 billion for the second quarter of 2020, an increase of 12.5 percent. For the six months ended June 30, 2021, operating revenues were $11.11 billion, compared with $9.64 billion for the corresponding period in 2020, an increase of 15.3 percent. These increases were primarily due to higher fuel costs. Colder weather in the first quarter 2021 also contributed to the increase for the six months ended June 30, 2021.

Southern Company’s second-quarter earnings slides with supplemental financial information, including long-term earnings guidance, 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 Andrew W. Evans will discuss earnings and provide a general business update, including an update on the Vogtle units 3 and 4 construction project and earnings guidance. Investors, media and the public may listen to a live webcast of the call and view associated slides at https://investor.southerncompany.com/events-and-presentations/default.aspx. A replay of the webcast will be available on the site for 12 months.
