ATLANTA – Southern Company today reported first-quarter earnings of $862 million, or 79 cents per share, in 2023 compared with earnings of $1.03 billion, or 97 cents per share, in the first quarter of 2022.

Excluding the items described under “Net Income – Excluding Items” in the table below, Southern Company earned $867 million, or 79 cents per share, during the first quarter of 2023, compared with $1.03 billion, or 97 cents per share, during the first quarter of 2022.

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

Adjusted earnings drivers for the first quarter 2023, as compared with 2022, were increased depreciation and amortization, milder weather and higher interest expense, partially offset by higher revenues associated with rates and pricing at the company’s regulated utilities.

First-quarter 2023 operating revenues were $6.5 billion, compared with $6.6 billion for the first quarter of 2022, a decrease of 2.5 percent.

“Southern Company delivered a solid start to 2023 despite the mildest weather on record for a first quarter in the Southeastern United States,” said President Christopher C. Womack. Added Womack, “We are



encouraged by continued strong residential customer growth in both the electric and gas sectors, as well as healthy economies and a robust economic development pipeline in our service footprint.”

Southern Company’s first-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 Womack and Chief Financial Officer Daniel S. Tucker 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. A replay of the webcast will be available on the site for 12 months.
