ALABAMA POWER CO

(a)Evaluation of disclosure controls and procedures.

As of the end of the period covered by this Quarterly Report on Form 10-Q, Southern Company, Alabama Power, Georgia Power, Mississippi Power, Southern Power, and Southern Company Gas conducted separate evaluations under the supervision and with the participation of each company's management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon these evaluations, the Chief Executive Officer and the Chief Financial Officer, in each case, concluded that the disclosure controls and procedures are effective.

(b) Changes in internal control over financial reporting.

There have been no changes in Southern Power's or Southern Company Gas' internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) during the third quarter 2026 that have materially affected or are reasonably likely to materially affect Southern Power's or Southern Company Gas' internal control over financial reporting.

In September 2026, Southern Company, Alabama Power, Georgia Power, and Mississippi Power implemented a new customer billing application. As a result, there were certain changes to processes and procedures, which resulted in changes to Southern Company's, Alabama Power's, Georgia Power's, and Mississippi Power's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended). These changes in internal controls were not made in response to any identified internal control deficiency.
