Market outlook for 2026

The market situation is expected to remain favourable in the key market segments of Enersense's strategy in 2026. In all of the company's operating countries, investments are being made to increase the capacity and reliability of electricity and telecommunications networks. Data centres, in particular, will increase capacity needs. Cautiously positive development is expected in clean energy transition investments. Individual large investment projects may have an impact on market development.

Guidance for 2026 (unchanged)

Enersense estimates its adjusted EBITDA to be EUR 19–23 million in 2026.

In 2025, the adjusted EBITDA for the core businesses was EUR 18.8 million. In 2026, Enersense discontinues separate reporting of core business figures as the strategic focusing is completed.

Key figures

CEO Kari Sundbäck

In the first quarter, we continued our strong order book growth and improved our underlying business. Going forward, we expect 2026 to show clear progress towards our strategic targets.

Our underlying business is performing well. In the first quarter, the revenue was on the comparison period level when excluding the units sold or discontinued in 2025. The adjusted EBITDA declined but the profitability of our underlying business improved, as the comparison period was positively impacted by a EUR 1 million provision release related to a dispute won. We maintain our full-year guidance and expect to see increasing earnings and growth especially in the second half of the year.

Our order book continued to grow for the fourth quarter in a row, totalling EUR 413 million at the end of the quarter. The order book of the Power Business Unit was at a record high. However, high activity in the electricity grid makes our customers order projects earlier in advance due to long lead times in critical components. As a result, orders stay in the order book longer before execution.

Increase in strategic growth target and in data centre focus
In June 2025, we published our strategy aiming to be a trusted lifecycle partner for our customers. Our strategy is based on a simple principle: focusing on our customers’ success shapes our 2028 ambition. Since the strategy launch in June 2025, the addressable market has developed favourably. Notably, electricity consumption is expected to double within ten to fifteen years in Finland and in Sweden.

As demand for our strong data centre related expertise has also grown, we added data centres as a separate customer segment to our strategy after the review period. This addition increases customer centricity, while the strategy otherwise remains unchanged.

Few companies have expertise as strong and diverse as Enersense when it comes to data centre needs. We are aiming for significant growth in data centre substations, power lines, data connections, and heat recovery solutions in Finland in the coming years. To reach this goal, we have established a Data Centre Unit to bring together our diverse expertise and offering for customers – making our expertise available to data centre developers more effectively and quicker.

After the review period, we increased our compound annual growth rate target to 6–7% (previously 4–5%) for the strategy period 2025–2028. We also changed the profitability target to an EBITDA margin over 7%, which equals the same profitability level as the previous EBIT margin target of over 5%, and changed the net gearing target to below 85% from the previous 100%.

Safety is more important than ever
During the quarter, we faced an extremely sad loss. One of our colleagues had a fatal traffic accident during his workday in Finland. Once again, I would like to express my sincere condolences to the loved ones of our late employee.

The investigation of the accident is still ongoing, and we will take all the learnings once we understand the causes. Every day, we choose to do our best to follow everything we have ever learned about safety – for ourselves and our colleagues. Keeping safety as our highest priority has never been this clear for us.

Continued emphasis on value creation
Looking ahead to the rest of the year, our focus is on continuing to deliver new value to customers, materialising the growth in our order book and on securing profitability improvements from the Value Uplift programme.

Enersense is in a good position at the heart of growing critical infrastructure markets. The first quarter was a good start for the year.
