-- US natural gas utility One Gas (OGS) Monday reported a decline in gas sales volume, despite a growth in customer base and a warmer weather, resulting in lower Q1 revenue.
For the quarter ended March 31, natural gas volumes delivered across all sectors dropped year over year to 119.0 billion cubic feet from 144.6 Bcf, while the number of customers grew to 2.32 million from 2.31 million.
Volumes sold mainly to the residential, commercial, and industrial customers fell to 59.9 Bcf from 79.3 Bcf. Corresponding revenue weakened to $769.9 million from $870.4 million.
Gas delivered to the transportation sector also decreased to 59.1 Bcf from 65.3 Bcf. The segment revenue eased to $40.1 million from $43.8 million.
The company saw weaker demand and revenue despite a warmer weather. During the period, weather across the company's service areas was 21% warmer than normal. In the same quarter of 2025, weather was 5% colder than average.
The impact of warmer weather on demand and financial results was "tempered by weather normalization mechanisms," the company said.
Oklahoma, Kansas, and Texas all experienced warmer weather during the quarter, with the number of customers also increasing versus a year earlier, data showed.
