Primeo Energie delivered solid results in 2025, increasing its net profit despite a decline in revenue. At the same time, the cooperative allocated more than CHF 11 million from its earnings to ease future tariffs in the basic supply segment. Primeo Energie remains financially well positioned to continue executing its investment and growth strategy.

Key highlights at a glance:

• Net profit rises to CHF 109 million, EBIT at CHF 127 million, revenue at CHF 1.8 billion
• Strong growth in France: 120,000 new residential customers; Swiss electricity business returns to slight profitability
• Network business under pressure due to declining industrial demand and regulatory constraints
• CHF 477 million invested over the past three years; more than CHF 200 million planned for 2026
• Broad diversification across segments and countries strengthens resilience in a volatile market environment

After several turbulent years, the energy market environment stabilized in 2025 for the first time since 2020. In this context, Primeo Energie generated revenue of CHF 1.8 billion, down CHF 392 million compared to the previous year (CHF 2.3 billion). This decline is mainly due to lower electricity prices and reduced overall sales volumes in Switzerland. Operating profit (EBIT) increased from CHF 124 million to CHF 127 million, while net profit rose from CHF 91 million to CHF 109 million. The consolidated balance sheet total remained stable at CHF 3 billion. The equity ratio improved slightly to 59% (previous year: 56%), underlining the company’s solid financial position.

The increase in EBIT and net profit was primarily driven by the Energy Solutions segment. To further strengthen financial stability, the Primeo Energie Group selectively adjusted its business portfolio, divesting activities that lacked sufficient scale or profitability. This included the sale of wind power assets in Norway and the electric mobility business in Switzerland.

Primeo Energie is well positioned to continue its investment and growth strategy. Over the past three years, the Group invested a total of CHF 477 million, with more than CHF 200 million planned for 2026. Investments are primarily focused on expanding generation capacity in electricity and heat.

Decarbonization, decentralization and digitalization advancing

During the reporting year, Primeo Energie consistently implemented measures from its updated corporate strategy. The transition of energy production towards renewable sources continued to progress. In autumn 2025, for example, the new heating plant of the Aesch district heating network was commissioned. Together with the new facility in Arlesheim, it represents a key building block for decarbonized district heating in the Birs Valley.

Decentralized electricity generation also continued to grow. By the end of 2025, 9,740 photovoltaic systems were in operation in Primeo Energie’s grid area, an increase of 903 compared to the previous year. Electricity-related services also expanded. The number of metering points in collective self-consumption schemes increased by nearly 31% to around 19,300 (previous year: 14,800). The “equalio” balancing energy pool managed by Primeo Energie grew from 261 to 276 flexible generation units and also participates in the winter reserve. The gradual expansion of these services in the French market supports business scaling and the strategic shift from a pure electricity supplier to an integrated provider of energy solutions. At the same time, processes, assets and services are becoming increasingly digitalized, as reflected in the rollout of smart meters, the expansion of the “Heat and Power of the Future” website, and the new “Hey Primeo” app.

Segment performance: strong energy solutions, challenges in networks

The Group structure and geographical diversification continue to act as stabilizing factors. The French business remains a key growth driver in the Energy Solutions segment, with around 120,000 new residential customers acquired in 2025. The Swiss electricity business also developed positively and returned to slight profitability for the first time in several years.

The Networks and Services segment continues to face a challenging regulatory environment. Lower energy volumes transported through the grid resulted in reduced revenues. In the basic supply segment, procurement costs during the energy crisis exceeded the levels assumed in tariff calculations, and regulatory constraints prevent these additional costs from being fully passed on. In addition, Primeo Energie is foregoing more than CHF 11 million in profits to ease future tariffs, on top of CHF 25 million already granted twice in previous years. This resulted in a loss in the segment. Structural trends further weigh on the business: declining industrial electricity consumption, more energy-conscious customer behavior, and increasing self-generation through photovoltaic systems. These trends are expected to continue.

The Heat and Industrial Solutions segment developed solidly. Several strategic projects, including the Lower Wiggertal district heating network, the majority acquisition of Energie Einsiedeln AG, and new or expanded heating networks in Muttenz, Aesch and the Birs Valley, are strengthening the growth base. However, mild weather conditions dampened demand.

Despite weather- and market-related fluctuations, the Production segment confirmed its stability, supported by a broadly diversified portfolio of hydropower, photovoltaic and wind assets across six countries, as well as long-term supply agreements. The commissioning of Primeo Energie’s first battery storage system in Kappel (SO) also marked an important milestone.

Outlook

In 2026, priorities will include further development of the Swiss electricity business, expansion of international activities, and implementation of new regulatory requirements in the network sector. Given ongoing geopolitical uncertainties and regulatory changes, energy prices are expected to remain volatile. The regulatory environment in Switzerland is leading to declining profitability in the basic supply segment, which is likely to significantly reduce investment activity, particularly in electricity networks.
