Wärtsilä has had three reporting segments since 1 April 2025: Wärtsilä Marine, Wärtsilä Energy, and Wärtsilä Energy Storage. The Portfolio Business was reported under Other business activities.
On 1 June 2026, Wärtsilä announced that it had completed the divestments of its Portfolio Businesses, and with the completion of the latest transactions, Wärtsilä Portfolio Business no longer has any remaining business activities.
On 15 June 2026, Wärtsilä announced the establishment of a joint venture for its Energy Storage business, and in the second quarter of 2026 Wärtsilä Energy Storage will cease to be a separate reporting segment. At the same time, its financial targets will no longer apply, and demand guidance will be suspended.
Consequently, from the second quarter of 2026 onwards, Wärtsilä will have two reporting segments: Wärtsilä Marine and Wärtsilä Energy.
Wärtsilä presented new combined financial targets for its Marine and Energy businesses, as well as separate financial targets for the Energy Storage business, on 1 April 2025.

Operating margin targets are long term targets. In the short term, selective entry to new markets and related investments are expected to burden Energy Storage profitability.
Energy Storage cease to exist as a separate reporting segment following the establishment of the joint venture, as a result of which the financial targets for Energy Storage will also be discontinued in the second quarter of 2026.
Wärtsilä’s industry-leading service network is a key enabler for maximum uptime, reliability, and total lifecycle solutions, all of which ensure customer success. Our network provides preventive, responsive, and optimised service, as well as lifecycle upgrades and remote support throughout the lifecycle of an installation. With our over 3,500 quality field service professionals and technical experts around the globe, we can provide our customers with timely support wherever needed.
Wärtsilä has significant growth opportunities in all steps of the service value ladder. In transactional services, we support our customers by leveraging digital solutions for customer intelligence and automated lead management.
In April 2025, Wärtsilä announced an investment of approximately EUR 50 million focused on enhancing testing facilities and accelerating the development of low- and zero-carbon technologies, with the aim of shortening development cycles and bringing new solutions to market more efficiently.
Building on this foundation, Wärtsilä moved forward with significant production investments. In February 2026, the company announced an investment of approximately EUR 140 million to increase production capacity by 35%, followed by an additional EUR 90 million investment in May 2026. Together, these steps will increase total capacity by around 65% compared with 2025 technical production capacity, with expansion scheduled for completion in phases between 2028 and 2029. Once all capacity expansions will have been commissioned, we will be able to produce 120% more gigawatts compared to the operational level in 2025.
Moving up the service value ladder, we deliver enhanced performance through optimised maintenance and performance-based service agreements, where we guarantee agreed performance levels by leveraging connectivity, big data, and analytics. The green transition is expected to represent a clear growth path for Wärtsilä.
At Wärtsilä, we believe that there will be a need for a broad array of solutions to decarbonise marine and energy. Different solutions will be used in different applications and in different geographies. There will be a gradual shift to new technologies, blending different types of fuel. Our in-house focus will remain on the development of core technologies. By partnering with technology providers in areas such as fuel cells, we can ensure a broad solution offering for our customers.
We continue to see strong synergies between marine and energy in research and development (R&D) and the manufacturing of new technologies. Throughout the decarbonisation transformation, we continue to invest ~4% of net sales in R&D. In 2025, we announced an expansion of Wärtsilä’s R&D testing capabilities at the Sustainable Technology Hub in Vaasa, Finland, thereby strengthening our capacity to test more sustainable fuels and meet the growing demand for sustainable technologies.
