Neuvoa Advisors advises on the merger of Lumme Energia Oy with Oomi Oy, aiming to create Finland's largest electricity retailer with over 800,000 customers.

Target Information

Suur-Savon Sähkö Oyj, a company operating in the Järvi-Suomi region, has engaged Neuvoa Advisors as its advisor in a strategic business transaction. This deal involves the merger of its subsidiary, Lumme Energia Oy, with Oomi Oy, a nationally-operating electricity company. If completed, this merger will establish the newly formed entity as the largest electricity retailer and energy service provider in Finland, boasting a customer base of over 800,000 nationwide.

The completion of this transaction hinges on the approval from the Finnish Competition and Consumer Authority. Plans are in place for all Lumme Energia customers to transition to Oomi by January 1, 2026; however, this timeline will be refined following regulatory review. Importantly, the merger will not affect customer agreements, their terms, durations, or pricing, thus requiring no action from customers.
