The group's financial performance was bolstered by a 1.96% rise in total income, reaching RON 8.71 billion (€1.76 billion). This growth was primarily driven by a 10.01% surge in underground storage revenue and an increase in the volume of gas delivered. Notably, 80.8% of gas deliveries in 2025 were made at regulated prices, a sharp increase from 55.5% in the previous year.

Efficiency gains also contributed to the bottom line, with total expenses dropping by 1.44% to RON 4.88 billion (€983.8 million). This reduction was largely attributed to a 25.3% decrease in tax-related expenses. Because revenue from gas sold at regulated prices is exempt from windfall tax, the company saw this specific tax burden fall by RON 434.17 million (€87.5 million), or 36.14%, year-on-year.

While gas remains the core business, the electricity segment saw mixed results. Revenues from electricity sales rose to RON 382.03 million (€77.0 million), even though production fell by 14.8% to 750.1 MWh. 

The company's EBITDA also showed strong growth, rising 7.91% to RON 4.41 billion (€888.0 million). At the close of 2025, Romgaz maintained a workforce of 5,809 employees and reported that natural gas storage capacity was 100% contracted.
