ONE Gas (OGS) Q4 2025 earnings review
Regulatory Execution Drives Double-Digit Income Growth
ONE Gas delivered a robust Q4, with Net Income rising 12% YoY and Full Year Net Income up 18.5%. The strategy of aggressive regulatory recovery—specifically new rate implementation and the benefits of Texas House Bill 4384—is effectively overpowering inflationary O&M pressures. Operating Cash Flow for the year surged 57% to $579M. Management issued bullish FY26 guidance, projecting 7-9% adjusted earnings growth, signaling an acceleration from historical trends.
🐂 Bull Case
The $116M full-year revenue increase from new rates proves the efficacy of OGS's regulatory strategy. The implementation of Texas HB 4384 and various riders has successfully reduced regulatory lag.
FY25 Operating Cash Flow jumped to $578.8M from $368.4M in FY24. This +57% improvement strengthens liquidity and supports the increased $800M capital plan for FY26 without stressing the balance sheet.
🐻 Bear Case
Operating and Maintenance expenses continue to climb, up $10M in Q4 YoY (+4.2%). Employee-related costs accounted for $4.2M of this increase, indicating persistent labor inflation that requires constant rate adjustments to offset.
While interest expense moderated in Q4 due to lower commercial paper rates, the company remains capital intensive ($800M FY26 Capex). Any 'higher-for-longer' interest rate environment serves as a drag on the bottom line.
⚖️ Verdict: 🟢
Bullish. ONE Gas is executing a textbook utility playbook: converting capital investment into rate base growth efficiently. The surge in cash flow and accelerating guidance range (7-9% growth vs historical 4-6%) suggests a structural shift in earnings power.
Key Themes
Regulatory Rate Relief
New rates were the primary engine of growth, contributing $23.8M to Operating Income in Q4 alone and $116.0M for the full year. This effectively offset the $20.6M increase in depreciation and $17.0M rise in employee costs for the year.
Labor Cost Inflation
Employee-related costs rose $4.2M in Q4 and $17.0M for the full year. While some of this supports in-sourcing initiatives (line locating), it remains a sticky expense line that threatens operating leverage if rate cases lag.
Interest Expense Stabilization
Reversing. For the first time in several quarters, Net Interest Expense became a tailwind rather than a headwind in Q4, decreasing by $2.9M YoY. Management attributes this to lower commercial paper rates and the implementation of Texas HB 4384, providing breathing room for EPS.
Weather Normalization Mechanisms
Stable. Q4 weather was 22.7% warmer than normal, yet the financial impact was negligible due to effective weather normalization mechanisms. This underscores the stability of the regulated earnings stream regardless of climate volatility.
Residential Customer Growth
Stable. Residential sales increased $1.3M in Q4 and $6.6M FY25 primarily due to net customer growth in Oklahoma and Texas. The company continues to see organic meter growth despite broader economic uncertainty.
Other KPIs
Accelerating. Cash flow from operations surged 57% YoY (from $368.4M in FY24), significantly outpacing net income growth. This quality-of-earnings improvement was driven by working capital management and deferred tax mechanics.
Stable. Came in essentially flat vs FY24 ($762.1M), demonstrating discipline. However, guidance points to a ramp-up to $800M in FY26 to fund system integrity and extension projects.
Decelerating. Down from $39.8M in 24Q4. This marks a pivotal shift from the rising interest cost trend seen throughout FY23 and early FY24.
Guidance
Accelerating. The midpoint ($298M) implies ~12.8% growth over FY25 GAAP Net Income ($264M). Management cites continued rate relief and customer growth as key drivers.
Accelerating. Midpoint of $4.71 represents 7.8% YoY growth over FY25 Actuals ($4.37). This is notably higher than the historical 4-6% target range, reflecting confidence in the new Texas regulatory framework.
Accelerating. An increase from the ~$760M run-rate of the last two years. $230M is specifically allocated for extensions to new customers, signaling aggressive pursuit of growth.
Accelerating. Management explicitly raised the long-term growth outlook (previously often cited as 5-7% EPS growth), now targeting 7-9% net income growth and 5-7% EPS growth.
Key Questions
Large Load Timeline
With $230M allocated for new customer extensions in 2026, how much of this is specifically tied to the data center and power generation opportunities mentioned in previous quarters, and when do these meters turn revenue-positive?
O&M Trajectory
Q4 O&M expenses grew at a faster clip (+4.2%) than the full year average target. Is this labor inflation structural, and should we model >4% O&M growth for FY26?
Equity Needs
With Capital Expenditures stepping up to $800M, what is the specific timing and volume of the remaining equity settlements required for FY26?
