Highlights
In banking and finance, the firm has a particular strength in advising on large scale project financings in Finland. For example, the firm assisted NREP in the development of residential construction project at Arabia Shopping Centre. The building, one constructed, is expected to be one of the most energy efficient residential buildings in Finland.
Another notable highlight of the firms work includes acting as legal adviser to Purmo Group, a listed company specialized in sustainable indoor climate comfort solution, on the voluntary cash tender offer made by Project Grand Bidco (UK) Limited for the total issued and outstanding shares in Purmo Group. The firm also played a role in the delisting of Purmo Group from Nasdaq Helsinki Stock Exchange as a result of the acquisition.
