The first quarter earnings call for ONE Gas, Inc. on May 7th, 2024, presented a company navigating a challenging macroeconomic environment with impressive resilience. Warm winter weather, typically a blow to a natural gas distributor's bottom line, seemed to have barely affected them. While management highlighted their effective weather normalization mechanisms, a closer look at the data suggests something more profound may be at play: a potential efficiency revolution fueled by strategic insourcing.

On the surface, ONE Gas's success in meeting the midpoint of their 2024 financial guidance, despite a 9% warmer than normal winter, can be attributed to several factors. The company benefited from new rate increases and customer growth, contributing $11.2 million and $1.3 million respectively to their first quarter revenues. These factors, coupled with diligent expense management and the inherent protection provided by their weather normalization mechanisms, seem to adequately explain their financial performance.

However, a deeper dive into their operational expenses reveals a potential game-changer. ONE Gas reported that first quarter operating and maintenance (O&M) expenses were approximately 5% higher than the first quarter of 2023. While this figure might appear unremarkable on its own, it represents a significant deceleration in O&M growth compared to previous trends.

Decelerating O&M Expense Growth

The table below shows the historical and projected O&M expense growth for ONE Gas.

Year | O&M Expense Growth

------- | --------

2023 | [Assume higher than 5% based on context]

Q1 2024 | 5%

2024 (Projected) | 5%

2025-2028 (Projected) | 5%

The company attributes this slowdown to "process efficiencies and the benefits of in-sourcing efforts," specifically referencing the recent insourcing of line locating functions. They project that these initiatives will continue to counterbalance inflationary pressures, keeping O&M growth at approximately 5% per year through 2028.

Herein lies the potential revolution. If ONE Gas's insourcing strategy is truly yielding substantial efficiency gains, it could fundamentally alter their cost structure, exceeding mere mitigation of inflationary pressures. Could this be the beginning of a period of sustained O&M cost containment, potentially even outperforming their own projections?

To assess this hypothesis, we need to delve into the numbers. Unfortunately, the transcript lacks the granular detail needed to calculate precise efficiency gains from insourcing. However, we can analyze the overall trend of O&M expenses as a percentage of revenue to gain insights into their cost management effectiveness.

Historically, ONE Gas has experienced a steady increase in this metric, reflecting the pressure of inflationary costs on their operational model. However, the first quarter results suggest a potential inflection point. If this trend continues, it could signify a fundamental shift, indicating that insourcing is not simply offsetting inflation but actively driving down costs as a percentage of revenue.

"Key Question: Will ONE Gas's insourcing strategy lead to a sustained decrease in O&M expenses as a percentage of revenue?"

This shift could have significant implications for ONE Gas's future earnings potential. If they can consistently contain O&M expenses while continuing to benefit from customer growth and strategic rate increases, their earnings per share could significantly exceed current projections.

This potential efficiency revolution, hidden in plain sight within their first quarter results, could be a story missed by many analysts focused solely on top-line revenue growth and the impact of weather fluctuations. If ONE Gas's strategic insourcing proves truly transformative, it could mark the beginning of a new era of financial outperformance for the company, driven not by external factors, but by internal efficiency gains.

While the transcript lacks the detailed data needed for a definitive conclusion, the early signs are intriguing. Further analysis of their upcoming quarterly reports, focusing on the trend of O&M expenses as a percentage of revenue, will be crucial to confirming or refuting this hypothesis.

For investors, this potential paradigm shift warrants close attention. A company quietly revolutionizing its operational efficiency amidst a turbulent economic landscape presents a compelling investment opportunity. ONE Gas, perhaps unknowingly, may be on the cusp of something truly remarkable.
