Key Takeaways
Southern Company closed fiscal 2025 (calendar year ended December 31, 2025) at $29.55 billion of revenue, up 10.6% YoY — driven by data-center load growth in Georgia + customer + usage growth across the state-regulated utilities. Adjusted EPS of $4.30 was at the top of FY25 guidance range (+6% YoY, +9% average annual growth from 2023). Diluted EPS $3.92 (vs $3.99 FY24, slight decline reflecting share count + interest expense). Net income $4.34B (vs $4.40B FY24). The structural read: weather-normalized retail electricity sales grew 1.7% FY25 vs 2024, with Georgia Power +2.5% including all 3 customer classes up — and commercial sales +17% YoY for the second year in a row driven by large-load data center customers. Industrial sales grew 1.4%; residential added 39K new electric customers + 25K new natural gas. Q3 FY25: 4 contracts with large-load customers >2 GW signed in 2 months in GA + AL. Georgia Power filed updated load forecast supporting need for 10 GW of capacity resources — the structural data center demand that's driving the FY25-FY30 capex cycle. Free cash flow was -$3.59B (vs +$0.83B FY24, due to capex acceleration); capex $13.4B (+50% from $8.96B FY24); dividends $3.02B; zero buybacks. Total debt $65.82B (vs $66.28B FY24).

Georgia Power — the data-center engine
The structural growth driver:
- Commercial sales +17% YoY for 2 consecutive years (FY24 + FY25) — driven by large-load data center customers
- 39K new electric customers + 25K new natural gas customers added FY25
- Industrial electricity sales +1.4% (recovery)
- Q3 FY25: 4 large-load contracts >2 GW signed in 2 months (GA + AL)

Alabama Power
Vertically integrated; co-signed some of the >2 GW data center large-load contracts with Georgia Power. Stable rate base growth.
Southern Company Gas (4 LDCs)
Atlanta Gas Light + Nicor Gas (Illinois) + Chattanooga Gas + Virginia Natural Gas. Authorized rate base has tripled since acquisition. Active in data center markets (gas-supplied generation). Stable mid-single-digit EPS contribution.
Southern Power (wholesale)
13+ GW capacity. Opportunities for remarketing existing capacity, up-rating, and adding new generation tied to data center demand. Long-term industry-leading portfolio.
Smaller Subsidiaries
PowerSecure (distributed energy + microgrids) + Southern Telecom (fiber backbone) — growth optionality.
Capex Acceleration
- FY25 capex $13.4B (+50% from $8.96B FY24); FY23 $9.10B
- Multi-year buildout to support 10 GW capacity expansion
- $1.8B equity issued through ATM program in Q3 FY25 (capital structure support)
- $4B debt issuance in Q3 FY25
Customer concentration. Highly fragmented (9M+ customers across utilities) but data-center large-load customer concentration in commercial segment is meaningful and growing.
Geographic mix. Southeast US (GA + AL + MS) ~70%, plus 4-state natural gas LDCs.
Scale anchors. ~28,000 employees. ~9 million customers across electric + gas. ~46 GW total generation capacity (vertically integrated + Southern Power).
Key core metrics (3-year trend)
1. Revenue and the data-center step
| FY23 | FY24 | FY25 | |
|---|---|---|---|
| Revenue ($B) | 25.25 | 26.72 | 29.55 |

| GA Power commercial sales YoY | — | +17% | +17% |
| Weather-normal retail YoY | — | — | +1.7% |
The Georgia Power commercial +17% for 2 consecutive years is the cleanest single data point on data-center load growth in US utility coverage.
2. Earnings — adjusted EPS at top of guide
| FY23 | FY24 | FY25 | |
|---|---|---|---|
| Operating income ($B) | 5.83 | 7.07 | 7.27 |
| Net income ($B) | 3.98 | 4.40 | 4.34 |

FY25 corporate structure: data-center load growth meets multi-year capex cycle
FY25 confirmed Southern Company as a clean beneficiary of the AI data-center capex cycle reaching the regulated electric utility layer. Georgia Power commercial sales +17% YoY for 2 consecutive years; 4 large-load >2GW customer contracts signed in 2 months Q3; 10 GW capacity resources needed per updated Georgia Power load forecast. The capex cycle has commenced — FY25 $13.4B (+50%) — and likely sustains FY26-FY27 to build the generation + transmission needed to serve the contracted data-center load. The 4 analyst upgrades in 2 weeks (Feb-March) is the Street rerating to the data-center utility thesis. The two FY26 watch items: (1) does Georgia Power commercial sales sustain +15-20% growth as additional data centers come online; (2) capex pace + financing mix as ATM equity issuance + debt funding the multi-year buildout. The Q1 FY26 earnings print this week is the proximate event for measuring continued commercial sales growth + Q1 large-load customer commentary + capex / equity issuance guidance + Georgia IRP progression.
