Why it matters

  1. What Southern Company does

    Southern Company generates electricity and delivers gas to millions of customers across the Southeast, collecting regulated utility bills from households and businesses. It relies on massive capital deployment into generation assets to ensure regional power delivery.

  2. What it does best

    Southern operates as a regulated regional monopoly, anchoring its position with an 88.6% gross margin that outpaces peers like CEG at 43.9%. This structural moat arises from government-sanctioned service areas that prevent direct competition.

  3. The main risk

    Heavy reliance on debt financing creates vulnerability, leaving net debt at $71.0B while interest coverage sits low at 2.3x. If borrowing costs remain elevated, servicing this massive obligation will increasingly pressure earnings.

Quality, check by check

Scored against its own industry, from company filings.

ProfitabilityFair

Operating margin stands at 24.2% while net margin is 15.4%, remaining stable as heavy capital investments offset operational gains.

MoatFair

Regulatory lock-in protects its customer base across the Southeast, supported by a gross margin in the top decile of its sector at 81% percentile.

GrowthSlow

Revenue grew 10.6% to reach $30.2B, accelerating compared to past years as infrastructure spending drives expansion.

Financial healthWeak

Total debt sits at $72.6B against cash of $1.6B, while free cash flow registers negative at -$3.5B due to heavy capital spending: getting softer.
