Romanian hydropower producer Hidroelectrica has delivered a total shareholder return of approximately 141% in the three years since its Bucharest Stock Exchange listing, combining a strong share-price increase with cumulative dividend payments.
The company’s shares reached a record €41.80 equivalent by early July 2026, representing a capital gain of 111.5% since the July 2023 initial public offering. Cumulative dividends of approximately €5.80 per share lifted the reported total return to around 141%.
Hidroelectrica’s market capitalisation increased from approximately €8.9 billion at listing to €18.8 billion, more than doubling in three years. The number of shareholders expanded by 39% to around 57,000, demonstrating the company’s importance to the development of Romania’s domestic equity market.
The 2023 transaction was the largest European IPO of that year and the third largest globally. It gave international investors access to one of Southeast Europe’s most valuable renewable-generation portfolios while strengthening the depth and visibility of the Bucharest Stock Exchange.
The share-price performance was achieved despite difficult hydrological conditions. 2025 was described as the weakest hydrological year in three decades, placing pressure on generation volumes and increasing the importance of portfolio optimisation and commercial trading.
Hydropower earnings are inherently exposed to rainfall, reservoir levels and river inflows. Strong returns during a weak hydrological period suggest that investors rewarded the company’s balance sheet, low-carbon generation base, dividend capacity and strategic position in Romania’s electricity market rather than relying solely on short-term production growth.
Capital expenditure has risen rapidly. Hidroelectrica invested €39 million in 2023, €112 million in 2024 and €148 million in 2025. Its 2026 investment allocation of €266 million is 82% higher than the previous year and nearly seven times the level recorded in 2023.
The programme covers hydropower modernisation, unfinished hydro projects, storage, digitalisation and new renewable assets. The acquisition of UCM Reșița also added engineering and maintenance capabilities, potentially giving Hidroelectrica greater control over refurbishment schedules and technical performance.
The investment acceleration is essential because Hidroelectrica’s valuation increasingly depends on converting its strong balance sheet into durable generation growth. Modernising ageing hydro assets can deliver additional output and flexibility with lower development risk than entirely new projects, while storage can increase the value of hydropower in a market experiencing greater solar-driven intraday volatility.
The company’s next phase will be judged less by the success of its IPO and more by the execution rate of its €266 million capital programme, particularly the conversion of budget allocations into commissioned capacity and higher operational availability.
