SOUTHERN CO GAS 8-K

What Happened Southern Company Gas disclosed on January 9, 2026 that its wholly owned subsidiary, Northern Illinois Gas Company (Nicor Gas), filed a general base rate case with the Illinois Commerce Commission seeking a $221 million increase in annual base rate revenues. The filing uses a projected test year for the 12-month period ending December 31, 2027 and specifies a requested return on equity of 10.35% and an equity ratio of 54.6%.

Key Details

• Filing date: January 9, 2026 (8-K disclosure).
• Requested increase: $221 million in annual base rate revenues.
• Test year: 12 months ending December 31, 2027.
• Regulatory parameters requested: 10.35% return on equity (ROE) and 54.6% equity ratio.
• Timing: Illinois Commerce Commission is expected to rule within the 11-month statutory time limit; rates would change only after the Commission’s decision. Outcome is not yet determined.

Why It Matters A favorable ruling could raise Nicor Gas’s regulated revenue and potentially improve Southern Company Gas’s utility earnings and cash flow; an unfavorable ruling would limit or prevent that revenue increase. Because the request is subject to regulatory review, the timing and magnitude of any impact on Southern Company Gas’s financial results remain uncertain. Investors should monitor regulatory filings and the Illinois Commerce Commission’s decision for updates that could affect future revenue and earnings.
