Inside information: Wärtsilä begins a strategic review of its Energy Storage and
Optimisation business

Wärtsilä Board of Directors has decided to initiate a strategic review of its
Energy Storage and Optimisation (ES&O) business. The strategic review aims to
assess options that would accelerate the profitable growth of the ES&O business
in a way that benefits its customers, employees, and the value creation for
Wärtsilä shareholders.

As part of this process, all potential alternatives will be considered. Such
alternatives could include different ownership options of the ES&O business from
continued full ownership to potential full or partial divestment of the business
or other possible strategic alternatives. Wärtsilä continues to be committed to
develop and invest in the ES&O business during the strategic review and remains
fully committed to its customers throughout the process.

On a twelve-month rolling basis, the ES&O net sales by the end of Q3 2023
amounted to EUR 983 million. On the same twelve-month rolling basis, the
business turned to profitability.

“We have made solid progress in our Energy Storage and Optimisation business and
the market continues to show remarkable growth. Thus, this is an opportune
moment for us to assess future options and define the best way to support the
growth of the business and create shareholder value,” says Håkan Agnevall,
President and CEO of Wärtsilä.

Wärtsilä Board of Directors has not set a timetable for the completion of the
strategic review. Wärtsilä will disclose the progress and conclusions of the
review according to applicable disclosure laws and regulations.
