Southern Company reports third-quarter 2026 earnings ATLANTA – Southern Company today reported third-quarter earnings of $2.0 billion, or $1.77 per share, in 2026 compared with earnings of $1.7 billion, or $1.55 per share, in the third quarter of 2025. For the nine months ended September 30, 2026, Southern Company reported earnings of $4.6 billion, or $4.02 per share, compared with $3.9 billion, or $3.56 per share, for the same period in 2025.

Excluding the items described under “Net Income – Excluding Items” in the table below, Southern Company earned $2.2 billion, or $1.94 per share, during the third quarter of 2026, compared with $1.8 billion, or $1.60 per share, during the third quarter of 2025. For the nine months ended September 30, 2026, excluding these items, Southern Company earned $5.0 billion, or $4.40 per share, compared with $4.1 billion, or $3.76 per share, for the same period in 2025.

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 third quarter of 2026, as compared with the same period in 2025, were warmer weather, increased usage and customer growth, growing revenue from large commercial and industrial customers along with higher earnings from Southern Power, partially offset by higher non-fuel Page 2 operating expenses and taxes other than income taxes, along with dilution impacts from additional shares outstanding.

Third-quarter 2026 operating revenues were $8.8 billion, compared with $7.8 billion for the third quarter of 2025, an increase of 13.0%. For the nine months ended September 30, 2026, operating revenues were $24.2 billion, compared with $22.6 billion for the corresponding period in 2025, an increase of 7.3%.

We know how important reliable energy is to our customers and take great pride in improving the communities and states we are privileged to serve.”

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 third quarter of 2026, as compared with the
same period in 2025, were warmer weather, increased usage and customer growth,
growing revenue from large commercial and industrial customers along with higher
earnings from Southern Power, partially offset by higher non-fuel
                                                                          Page 2
operating expenses and taxes other than income taxes, along with dilution
impacts from additional shares outstanding.

Third-quarter 2026 operating revenues were $8.8 billion, compared with $7.8
billion for the third quarter of 2025, an increase of 13.0%. For the nine months
ended September 30, 2026, operating revenues were $24.2 billion, compared with
$22.6 billion for the corresponding period in 2025, an increase of 7.3%.

“The Southeast is growing at a pace that is both unprecedented and
transformational, and we believe Southern Company is well positioned for today
and in the future,” said Chris Womack, chairman, president and CEO of Southern
Company. “Our scale, our experience and our customer-focused strategy allow us
to serve this growing demand in a responsible and sustainable manner, with the
same discipline, credibility and customer focus that have long defined our
company. We know how important reliable energy is to our customers and take
great pride in improving the communities and states we are privileged to serve.”

Certain information contained in this release is forward-looking information
based on current expectations and plans that involve risks and uncertainties.
Forward-looking information includes, among other things, statements concerning

certain factors that can cause actual results to differ materially from the
forward-looking information that has been provided. The reader is cautioned not
to put undue reliance on this forward-looking information, which is not a

other factors, many of which are outside the control of Southern Company;
accordingly, there can be no assurance that such suggested results will be
realized. The following factors, in addition to those discussed in Southern
Company’s Annual Report on Form 10-K for the year ended December 31, 2025,
Quarterly Reports on Form 10-Q for the quarters ended March 31, 2026, June 30,
2026 and September 30, 2026 and subsequent securities filings, could cause
actual results to differ materially from management expectations as suggested by
such forward-looking information: the impact of recent and future federal and
state legal and regulatory changes, including tax, environmental and other laws
and regulations to which Southern Company and its subsidiaries are subject, as
well as changes in application of existing laws, regulations and guidance; the
extent and timing of costs and legal requirements related to coal combustion
residuals; current and future litigation or regulatory investigations,
proceedings, or inquiries; the effects, extent, and timing of the entry of
additional competition in the markets in which Southern Company’s subsidiaries
operate, including from the development and deployment of alternative energy
sources; variations in demand for electricity and natural gas, including
uncertainties related to projected significant growth in electricity demand
driven primarily by data centers and other large load customers, and the related
requirement for substantial new generation and transmission investments,
creating capital access and revenue recovery risks for the
                                                                          Page 3
traditional electric operating companies; customer affordability matters;
available sources and costs of natural gas and other fuels and commodities; the
ability to complete necessary or desirable pipeline expansion or infrastructure
projects, limits on pipeline capacity, public and policymaker support for such
projects, and operational interruptions to natural gas distribution and
transmission activities; transmission constraints; the ability to control costs
and avoid cost and schedule overruns during the development, construction, and
operation of facilities or other projects due to challenges which include, but
are not limited to, changes in labor costs, availability, and productivity,
challenges with the management of contractors or vendors, subcontractor
performance, adverse weather conditions, shortages, delays, increased costs, or
inconsistent quality of equipment, materials, and labor, contractor or supplier
delay, the impacts of inflation and trade policies (including tariffs and other
trade measures) of the United States and other countries, delays due to judicial
or regulatory action, nonperformance under construction, operating, or other
agreements, operational readiness, including specialized operator training and
required site safety programs, engineering or design problems or any remediation
related thereto, design and other licensing-based compliance matters, challenges
with start-up activities, including major equipment failure or system
integration, and/or operational performance, challenges related to future
epidemic or pandemic health events, continued public and policymaker support for
projects, environmental and geological conditions, delays or increased costs to
interconnect facilities to transmission grids, and increased financing costs as
a result of changes in interest rates or as a result of project delays; legal
proceedings and regulatory approvals and actions related to past, ongoing, and
proposed construction projects, including state public service commission or
other applicable state regulatory agency approvals and Federal Energy Regulatory
Commission and U.S. Nuclear Regulatory Commission actions; the ability to
construct facilities in accordance with the requirements of permits and
licenses, to satisfy any environmental performance standards and the
requirements of tax credits and other incentives, and to integrate facilities
into the Southern Company system upon completion of construction; investment
performance of the employee and retiree benefit plans and nuclear
decommissioning trust funds and, with respect to retiree benefit plans, changes
in actuarial assumptions and differences between the assumptions and actual
values, any of the foregoing of which could cause additional funding
requirements; advances in technology, including the pace and extent of
development of low- to no-carbon energy and battery energy storage technologies
and the impact of advancing technology on data center and other large load
customer demand; performance of counterparties under ongoing renewable energy
partnerships and development agreements; state and federal rate regulations and
the impact of pending and future rate cases and negotiations, including rate
actions relating to return on equity, equity ratios, additional generating
capacity and transmission facilities, extension of retirement dates for fossil
fuel plants, and fuel and other cost recovery mechanisms; the ability to
successfully operate Southern Company’s electric utilities’ generation,
transmission, distribution, and battery energy storage facilities, as
applicable, and Southern Company Gas’ natural gas distribution and storage

risks involved in generation, transmission, and distribution of electricity and
transportation and storage of natural gas, including accidents, explosions,
fires, mechanical problems, discharges or releases of toxic or hazardous
substances or gases, and other environmental risks; the performance of projects
undertaken by the non-utility businesses and the success of efforts to invest in
and develop new opportunities; internal restructuring or other restructuring
options that may be pursued; potential business strategies, including

(1) Dilution is not material in any period presented. Diluted earnings per share
was $1.76 and $4.00 for the three and nine months ended September 30, 2026,
respectively, and $1.54 and $3.54 for the three and nine months ended September
30, 2025, respectively.

(2) Earnings include pre-tax charges of $118 million ($92 million after tax) and
$414 million ($322 million after tax) for the three and nine months ended
September 30, 2026, respectively, and $103 million ($80 million after tax, net
of noncontrolling interest impacts) and $168 million ($130 million after tax,
net of noncontrolling interest impacts) for the three and nine months ended
September 30, 2025, respectively, associated with accelerated depreciation and
decommissioning costs related to the repowering of certain wind facilities at
Southern Power Company. Accelerated depreciation and decommissioning costs
associated with the replacement of equipment will continue until the completion
dates of the repowering projects, which are projected to occur through the third
quarter 2027. At September 30, 2026, the remaining pre-tax accelerated
depreciation and decommissioning costs are projected to total approximately $100
million in 2026 and $135 million in 2027.

(3) Earnings for the three and nine months ended September 30, 2026 include
costs associated with the extinguishment of debt at Southern Company totaling
$43 million ($40 million after tax) and $54 million ($49 million after tax),
respectively, as a result of Southern Company's repurchase of certain
convertible senior notes and redemption of certain junior subordinated notes.
Earnings for the three and nine months ended September 30, 2026 also include $57
million associated with a change in tax benefits related to the extinguishment
of debt in 2025. Earnings for the nine months ended September 30, 2025 include
costs associated with extinguishment of debt at Southern Company totaling $129
million ($97 million after tax) as a result of Southern Company's repurchase of
certain convertible senior notes. Similar transaction costs may occur in the
future at Southern Company or one of its unregulated subsidiaries; however, the
amount and timing of any such costs are uncertain.

(4) Earnings for the three and nine months ended September 30, 2026 include an
estimated loss of $9 million ($7 million after tax) and $19 million ($14 million
after tax), respectively, at Southern Company Gas related to costs associated
with Nicor Gas capital investments disallowed by the Illinois Commerce
Commission in November 2025. Further charges may occur; however, the amount and
timing of any such charges are uncertain.

(5) Earnings include income tax charges of $4 million for the nine months ended
September 30, 2026 and 2025 related to the remeasuring of deferred tax assets
associated with the previously recognized estimated probable loss on Plant
Vogtle Units 3 and 4 due to changes in the State of Georgia corporate tax rate.
Additionally, earnings for the three and nine months ended September 30, 2025
include pre-tax credits to income of $33 million ($25 million after tax) related
to the estimated probable loss on Plant Vogtle Units 3 and 4 reflecting
revisions to Georgia Power Company's total project capital cost forecast
resulting from reductions in remaining expected site demobilization costs and
other contractor obligations. Site demobilization efforts were completed during
the third quarter 2025. Further charges and/or credits may occur; however, the
amount and timing are uncertain. Earnings for the three and nine months ended
September 30, 2025 also include charges (net of salvage proceeds), associated
legal expenses (net of insurance recoveries), and tax impacts related to
Mississippi Power Company's integrated coal gasification combined cycle facility
project in Kemper County, Mississippi. Dismantlement of the abandoned gasifier-
related assets was completed at the end of 2025. Site restoration activities are
substantially complete, and any additional costs are expected to be immaterial.

(6) Earnings for the nine months ended September 30, 2026 include a state income
tax refund of $9 million ($7 million after federal tax) at Southern Company Gas
associated with the 2018 disposition of Elizabethtown Gas, partially offset by
related contingency fee expenses of $2 million ($1 million after tax) incurred
in connection with obtaining the refund. Earnings for the three and nine months
ended September 30, 2025 include a pre-tax gain of $2 million ($1 million after
tax) related to the sale of a multi-use commercial facility development at
Alabama Power Company. Further impacts may result from past and future
disposition activities; however, the amount and timing of any such impacts are
uncertain.

(1) Dilution is not material in any period presented. Diluted earnings per share
was $1.76 and $4.00 for the three and nine months ended September 30, 2026,
respectively, and $1.54 and $3.54 for the three and nine months ended September
30, 2025, respectively.

(2) Earnings include pre-tax charges of $118 million ($92 million after tax) and
$414 million ($322 million after tax) for the three and nine months ended
September 30, 2026, respectively, and $103 million ($80 million after tax, net
of noncontrolling interest impacts) and $168 million ($130 million after tax,
net of noncontrolling interest impacts) for the three and nine months ended
September 30, 2025, respectively, associated with accelerated depreciation and
decommissioning costs related to the repowering of certain wind facilities at
Southern Power Company. Accelerated depreciation and decommissioning costs
associated with the replacement of equipment will continue until the completion
dates of the repowering projects, which are projected to occur through the third
quarter 2027. At September 30, 2026, the remaining pre-tax accelerated
depreciation and decommissioning costs are projected to total approximately $100
million in 2026 and $135 million in 2027.

(3) Earnings for the three and nine months ended September 30, 2026 include
costs associated with the extinguishment of debt at Southern Company totaling
$43 million ($40 million after tax) and $54 million ($49 million after tax),
respectively, as a result of Southern Company's repurchase of certain
convertible senior notes and redemption of certain junior subordinated notes.
Earnings for the three and nine months ended September 30, 2026 also include $57
million associated with a change in tax benefits related to the extinguishment
of debt in 2025. Earnings for the nine months ended September 30, 2025 include
costs associated with extinguishment of debt at Southern Company totaling $129
million ($97 million after tax) as a result of Southern Company's repurchase of
certain convertible senior notes. Similar transaction costs may occur in the
future at Southern Company or one of its unregulated subsidiaries; however, the
amount and timing of any such costs are uncertain.

(4) Earnings for the three and nine months ended September 30, 2026 include an
estimated loss of $9 million ($7 million after tax) and $19 million ($14 million
after tax), respectively, at Southern Company Gas related to costs associated
with Nicor Gas capital investments disallowed by the Illinois Commerce
Commission in November 2025. Further charges may occur; however, the amount and
timing of any such charges are uncertain.

(5) Earnings include income tax charges of $4 million for the nine months ended
September 30, 2026 and 2025 related to the remeasuring of deferred tax assets
associated with the previously recognized estimated probable loss on Plant

Additionally, earnings for the three and nine months ended September 30, 2025
include pre-tax credits to income of $33 million ($25 million after tax) related
to the estimated probable loss on Plant Vogtle Units 3 and 4 reflecting
revisions to Georgia Power Company's total project capital cost forecast
resulting from reductions in remaining expected site demobilization costs and
other contractor obligations. Site demobilization efforts were completed during
the third quarter 2025. Further charges and/or credits may occur; however, the
amount and timing are uncertain. Earnings for the three and nine months ended
September 30, 2025 also include charges (net of salvage proceeds), associated
legal expenses (net of insurance recoveries), and tax impacts related to
Mississippi Power Company's integrated coal gasification combined cycle facility
project in Kemper County, Mississippi. Dismantlement of the abandoned gasifier-
related assets was completed at the end of 2025. Site restoration activities are
substantially complete, and any additional costs are expected to be immaterial.

(6) Earnings for the nine months ended September 30, 2026 include a state income
tax refund of $9 million ($7 million after federal tax) at Southern Company Gas
associated with the 2018 disposition of Elizabethtown Gas, partially offset by
related contingency fee expenses of $2 million ($1 million after tax) incurred
in connection with obtaining the refund. Earnings for the three and nine months
ended September 30, 2025 include a pre-tax gain of $2 million ($1 million after
tax) related to the sale of a multi-use commercial facility development at
Alabama Power Company. Further impacts may result from past and future
disposition activities; however, the amount and timing of any such impacts are
uncertain.
