ERG stock holds near its yearly range as results guide valuation

ERG stock is quoted at EUR 18.44 on the primary Borsa Italiana venue as of September 21, 2026, giving investors a dated reference point for the renewable-energy group. The latest reported figures show revenue of EUR 742 million in fiscal year 2025 and installed renewable capacity of 3.8 gigawatts in the same period.

Revenue and capacity define the picture

ERG reported EUR 742 million of revenue for fiscal year 2025, compared with EUR 741 million in fiscal year 2024, while renewable capacity increased from 3.4 gigawatts to 3.8 gigawatts over the same comparison period. The combination points to a business whose operating scale expanded faster than headline revenue.

The group operates renewable-energy assets across several European markets, with wind and solar generation forming the core of its portfolio. Capacity growth is therefore the more direct operating measure, while revenue remains exposed to generation volumes, power prices and asset disposals.

Valuation depends on power prices

At EUR 18.44 on September 21, 2026, the stock price provides the market reference for assessing the reported fiscal-year figures. The fiscal year 2025 revenue base of EUR 742 million is only EUR 1 million above fiscal year 2024, so future valuation support depends more on capacity additions and profitability than on top-line growth alone.

For investors, the key counter-factor is the difference between installed capacity and realized earnings. A larger renewable portfolio can raise generation potential, but weather conditions, electricity prices, financing costs and project timing can affect the cash flow produced by that capacity.

ERG stock closes at EUR 18.44

ERG stock stood at EUR 18.44 on Borsa Italiana on September 21, 2026. The price should be read alongside fiscal year 2025 revenue of EUR 742 million and renewable capacity of 3.8 gigawatts, rather than as a standalone signal.
