### The Southern Company (SO) — Business Overview

#### Business Description
Southern Company is one of the largest US electric utility holding companies, serving 9M+ customers across Georgia, Alabama, Mississippi (electric) and Georgia/Illinois/Virginia/Tennessee (natural gas). Southern owns the largest US nuclear power station (Vogtle 1-4, 4,536 MW after completing Units 3 + 4 in 2024). The 2026 thesis: nuclear-powered utility uniquely positioned for the Southeast data center buildout — 75 GW potential pipeline + 11 GW already contracted. CEO Chris Womack (since 2023, succeeded Tom Fanning).

#### Revenue Model

### The Southern Company (SO) — Investment Catalysts & Risks

#### Bull Case Drivers

1. **75 GW data center pipeline + 11 GW contracted** — Southern (Georgia Power) has fully contracted 11 GW for large-load customers (up from 10 GW earlier) and is anticipating a 75 GW pipeline of potential data center interest. Q1 2026 data center usage +42% YoY. Commercial sales growing ~20% annually through end of decade. The Southeast US is becoming the AI data center hub.

2. **Vogtle 4,536 MW nuclear = unique baseload advantage** — Vogtle 1-4 is the largest US nuclear station. 24/7 dispatchable carbon-free baseload power is exactly what hyperscalers want for AI data centers. Unlike regions facing grid constraints, Southern's nuclear + grid investments make it one of the few utilities that can guarantee massive steady power draws. Georgia Power planning additional nuclear capacity.

3. **$81B 2026-2030 CapEx supports 6-8% EPS growth** — Southern raised 2026-2030 CapEx plan to $81B (+$5B). Rate-base growth at this pace supports 6-8% EPS CAGR. Combined with 23-year dividend Aristocrat status + 2.8% yield = ~9-11% total return potential for a regulated utility.

4. **Supportive Southeast regulatory environment** — Georgia + Alabama PSCs generally support "all-of-the-above" energy strategy + economic development. Rate cases tend to be favorable. State commissions have approved Vogtle 3+4 cost recovery + supported the $81B CapEx plan. The regulatory moat is one of SO's most underappreciated competitive advantages.

#### Bear Case Risks

1. **5.5x Debt/EBITDA + interest rate sensitivity** — Total debt $65B at 5.5x EBITDA is elevated even for a utility. With Fed pause or rates rising, interest expense compresses earnings + makes refinancing more expensive. Utilities are bond proxies — if 10-year yields rise, SO multiple compresses.

2. **Vogtle 3+4 cost overruns set precedent for nuclear** — Vogtle 3+4 went from $14B initial budget to $30B+. While completed, the cost overruns hurt ratepayers and created political backlash. Any new nuclear projects (Georgia Power exploring) face execution risk + political scrutiny. If new nuclear builds prove costly, the bull case requires more conventional capacity additions.

3. **$13B annual CapEx vs $10.5B operating cash flow = negative FCF** — Heavy CapEx requirements mean SO runs negative FCF and depends on debt + equity issuance to fund growth. If capital markets tighten or cost of debt rises sharply, the $81B plan slows.

4. **Data center demand concentration + commitment risk** — While 11 GW contracted is impressive, data center commitments can shift. If hyperscaler AI capex pauses or moves to other regions (Virginia, Texas competing), the 75 GW pipeline may not fully materialize. SO's growth thesis is partially correlated with hyperscaler capex.

#### Upcoming Events

- **Q2 2026 earnings (July 2026)** — Data center contract additions; CapEx update
- **Q3 2026 earnings (October 2026)** — Summer cooling demand + 2027 EPS guide
- **Georgia Power additional nuclear announcements** — Multi-quarter milestones
- **Hyperscaler data center commitments** — Direct demand visibility
- **Annual dividend increase**

#### Analyst Sentiment

Sell-side consensus is **Buy** with average price targets in the $110-125 range vs. recent ~$105 trading levels (~5-19% upside). Bulls cite Vogtle nuclear + 75 GW data center pipeline + Southeast growth + 23-year dividend track record. Bears focus on debt levels + interest rate sensitivity + Vogtle overrun precedent. SO is widely viewed as the best utility play on data center demand alongside NextEra.
