Letter to Stockholders

"There is no doubt
the world is rapidly
changing on many
fronts. At Southern
Company we are not
merely adapting to this
changing environment – we have the energy to lead the change.”

Dear Fellow Stockholders:

You are invited to attend the 2017 Annual Meeting of Stockholders at 10:00 a.m., ET on Wednesday, May 24, 2017, at The Lodge Conference Center at Callaway Gardens, Pine Mountain, Georgia.

2016 was a year of great growth and change as we continued to fill in the energy value chain to sustain growth.

  • We proudly welcomed more than 6,000 new colleagues and over 4.5 million customers with the addition of Southern Company Gas (formerly AGL Resources Inc.).
  • Our wholesale electric subsidiary, Southern Power Company (Southern Power), continued to acquire solar, wind and natural gas generation facilities, investing over $4.5 billion.
  • We acquired a 50% equity interest in the Southern Natural Gas pipeline system.
  • With the acquisition of PowerSecure International, Inc. (PowerSecure) and its strategic alliance with Bloom Energy for the deployment of fuel cell and battery storage technologies, we’re developing behind-the-meter infrastructure for customers across the country.

These decisions were all designed to help meet customers’ current and future energy needs with a focus on the continued execution of our customer-focused business model supporting constructive regulatory environments with healthy capital spending and returns on our investment. We now own and operate 11 premier state-regulated electric and gas utilities that are complemented by energy assets under long-term contract, including natural gas and renewable generation, interstate natural gas pipelines and behind-the-meter infrastructure. We aim to continue to deliver a superior, risk-adjusted total shareholder return (TSR) supported by regular, predictable and sustainable earnings and dividends.

I am also proud to report that we were recognized by DiversityInc as one of the “Top 50 Companies for Diversity” in 2016. DiversityInc also ranked Southern Company number one on its list of “Top 10 Companies for Opportunity.” This is especially meaningful because it testifies that we were recognized not only for cultivating a diverse workplace, but that we are also considered the number one company in America in which the individuals who comprise that diverse workforce are afforded the opportunity to advance their careers. In addition, we earned a perfect score from the Human Rights Campaign on their Corporate Equality Index for 2017.

We are taking advantage of the notice and access rules of the Securities and Exchange Commission (SEC) that allow us to furnish our proxy materials to you over the internet instead of mailing paper copies to each stockholder. We are mailing a Notice of Internet Availability of Proxy Materials beginning on or about April 7, 2017 to certain of our stockholders. The Notice contains instructions on how to access the proxy materials and vote your proxy. We believe this approach allows us to provide stockholders with a timely and convenient way to receive proxy materials and vote, while lowering the costs of delivery and reducing the environmental impact of the annual meeting.

Your vote is important. We urge you to vote promptly, even if you plan to attend the annual meeting.

Thank you for your continued support of Southern Company.

Thomas A. Fanning
