The company’s second-quarter results highlighted continued growth in electricity demand, supported by data centers and large industrial customers, while ongoing investments in generation, grid modernization and renewable energy strengthened its long-term growth prospects.

The Zacks Consensus Estimate for Southern Company’s 2026 earnings has increased 6.74% to $4.59 per share, while the 2027 estimate has risen 7.12% to $4.91. These upward revisions suggest growing analyst confidence in the company’s earnings outlook.

For investors, the pressing question is whether now is the right time to buy Southern Company stock or to wait. Let’s explore what makes the company an attractive investment and the potential risks that could influence that decision.
Why SO Stock Remains Attractive
Accelerating Electricity Demand: Southern Company is benefiting from accelerating electricity demand in the Southeast, particularly from data centers and large industrial customers. Weather-normal retail electricity sales rose 2.3% year to date, the strongest first-half growth in nearly two decades, while data center usage increased 55% year over year, supporting a durable load-growth outlook.
Large Pipeline of Contracted Demand: Southern Company has secured a substantial pipeline of large-load demand that can support utility growth. Contracts and agreements across its electric subsidiaries now exceed 17 gigawatts by the mid-2030s, while more than 75 gigawatts remain in the prospective pipeline and another 8 gigawatts are in late stages, including 3 gigawatts expected soon.
Long-Term OpenAI Contract: SO’s subsidiaryGeorgia Power's 3.2-gigawatt, 25-year contract with OpenAI provides Southern Company with long-duration demand visibility. The project is expected to begin service in phases from 2028 and includes 1 gigawatt of flexible demand response. The contract adds load while supporting reliability during periods of peak demand.
Customer Protections on Large-Load Contracts: Southern Company's large-load contracting structure reduces the risk that existing customers will bear the full cost of serving new data centers. Management said contracts include minimum bills covering at least 100% of incremental service costs, while many also include termination payments and high-quality collateral. Some dedicated assets also require customer contributions.
Strong Regulated Capital-Growth Opportunity: Southern Company has significant regulated investment opportunities, with its presentation showing $81 billion of projected capital expenditures from 2026 through 2030. About 95% is expected in state-regulated utilities, supporting projected rate-base growth of 9%. This provides a visible framework for long-term earnings expansion.
Risks That Could Weigh on SO’s Shares
Very High Capital Requirements: Southern Company faces substantial financing needs because rapid demand growth requires heavy investment in generation, transmission and distribution. The company used $6.76 billion for investing activities in the first six months of 2026, primarily for construction programs, while financing activities provided $3.83 billion. Continued capital intensity could pressure leverage and returns.
Continued Need for Equity Financing: Southern Company's growth strategy is increasingly dependent on external financing and additional equity. Management said it sourced another $700 million of equity in the second quarter and still expects $1.1 billion of remaining equity needs through 2030. Although the plan supports credit quality, additional share issuance can dilute per-share earnings.
Higher Borrowing Costs: Rising debt costs remain a headwind as Southern Company expands its infrastructure. Second-quarter interest expense at Georgia Power increased $30 million to $228 million, while higher average borrowings and interest on finance-lease power purchase agreements contributed to the increase. Continued construction spending could require more borrowing and keep interest expense elevated.
Regulatory Cost-Recovery Risk: Southern Company's earnings remain exposed to regulatory cost recovery and affordability pressures. Its traditional electric businesses must obtain timely recovery for major investments while customers face affordability concerns. Management also identifies capital access and revenue recovery risks tied to data center growth, so planned investments may not earn the expected returns.
Underwhelming Returns Raise Concerns: Over the past 12 months, SO has significantly underperformed both its peers and the broader utilities market, declining approximately 3%, against gains of 13.1% for the Electric Power sub-industry (ZSI193M) and 8.7% for the Utilities Sector (ZS14M). This weak relative performance highlights SO’s inability to keep pace with the broader utility sector.

Final Verdict on SO Stock
SO benefits from accelerating electricity demand in the Southeast, particularly from data centers and industrial customers, with retail sales up 2.3% year to date and data center usage rising 55% year over year. Its more than 17-gigawatt contracted demand pipeline, 25-year 3.2-gigawatt OpenAI agreement, customer protections on large-load contracts and $81 billion regulated capital-investment plan provide strong long-term growth and earnings visibility.
However, the company faces very high capital requirements, continued reliance on equity financing that could dilute per-share earnings, rising borrowing costs and increased interest expense. Regulatory cost-recovery and affordability concerns could limit returns on planned investments, while the stock’s roughly 3% decline over the past 12 months has significantly lagged the Electric Power sub-industry and the Utilities sector. Given this mix of strengths and potential challenges, investors should wait for a more opportune entry point instead of adding this Zacks Rank #3 (Hold) utility stock to their portfolios.
