EBITDA generated by the Enea Group in Q1 2026 was driven by thefollowing factors (as compared to Q1 2025):

The lower EBITDA in the Mining Area resulted from a decrease in revenuefrom sales of coal. Along with a lower coal sales volume, a lower salesprice was realized.

- In the Generation Area, a higher EBITDA was posted. The ConventionalPower Segment reported an increase in EBITDA, primarily due to a rise inthe CDS margin, higher revenues from the Capacity Market, and anincrease in the margin on the Green Unit, offset by a decline in themargin on electricity repurchase and lower revenues from BalancingCapacities. In the RES Segment, an increase in EBITDA was recorded,driven by stronger performance in the Wind Area. The Heat Segment saw animprovement in EBITDA, driven by an increase in the unit margin.

- The Distribution segment reported lower EBITDA. Despite an increase inthe realized margin from licensed operations, there was also an increasein operating costs and an increase in provisions for grid assets.

- In the Trading Area, the lower EBITDA was mainly due to a decrease inthe margin on the retail market. In addition, EBITDA was significantlyimpacted by an increase in the use of provisions (primarily provisionsfor Tariff G).
