Last earnings call, Jul 30, 2026 AI summary
- What they said
- Southern Company reported a strong second quarter 2026 driven by higher usage, customer growth and large-load data center contracts. Adjusted EPS was $1.13 for the quarter, $0.21 above prior year and $0.13 above the company's prior estimate. Management highlighted substantial recent contract wins: three projects in Alabama adding ~3 GW and a 3.2 GW, 25-year contract with OpenAI in Georgia (including ~1 GW of flexible demand response). Combined with earlier deals, Southern now has over 17 GW of large-load contracts by the mid-2030s. Utilities (Georgia Power, Alabama Power and Mississippi Power) are capturing the growth while maintaining rate stability (retail base rates held stable in Georgia and Alabama through 2029). Key drivers of the quarter included increased retail sales (weather-normal sales up 2.3% YTD), higher AFUDC from construction, gains from equity-method investments, and Southern Company Gas and other complementary businesses (e.g., PowerSecure). Offsets included higher interest expense from greater debt and dilution from equity issuance. Management described opportunities across FERC-regulated pipeline investments, Southern Power recontracting/upgrades as older tolling agreements roll off, and potential nuclear discussions with government and other partners. RFPs for generation needs are underway in Alabama and Georgia, with selection expected by year-end and certification through much of 2027. Management emphasized strong collateral and contract protections (minimum bills covering incremental costs and default/collateral protections), noted approximately $20–21 billion of collateral across the large-load portfolio on full ramp, and stressed that load ramp timing varies by project. Overall tone was upbeat and confident about execution, with cautious language around not getting ahead of regulators, political/public noise around data centers, and other execution/approval risks.
- Guidance
- Full-year 2026 adjusted EPS projected to be near or at the top of the $4.50 to $4.60 guidance range. Adjusted EPS estimate for Q3 2026: $1.50 per share. Management reiterated expectation to be in the top half of long-term earnings trajectory and noted target to reach ~17% FFO-to-debt by 2029.
- Risks flagged
- - Interest expense pressure from higher debt balances and dilution from equity issuance. - Regulatory and approval risk: RFP outcomes, certification processes (majority of clarity expected by late 2027) and not getting ahead of regulators. - Execution and timing risk for load ramp of large customers (actual ramp can vary vs. initial forecasts). - Political/public opposition and reputational risk related to data center builds in some counties/communities. - Potential cost overrun/financial exposure for large projects (nuclear) though management stated discussions are ongoing and Southern is not the immediate next builder. - Market and counterparty credit risk partly mitigated by collateral and minimum-bill structures (management highlighted ~ $20–21B collateral portfolio).
