The Board of Directors of Sitowise Group Plc ("Sitowise") has today on 24 March 2021 decided together with Intera Fund III Ky ("Intera") on the completion of the Offering (as defined below). The subscription price for the Offer Shares (as defined below) was EUR 8.20 per share in the Institutional Offering and the Public Offering (as defined below), and EUR 7.38 per share in the Personnel Offering (as defined below), which corresponds in total to a market capitalisation of Sitowise of approximately EUR 288 million immediately following the Offering. Demand in the Offering was strong from both Finnish and international investors and the Offering was multiple times oversubscribed. Trading of the shares in Sitowise (the "Shares") is expected to commence on the prelist of Nasdaq Helsinki Ltd ("Nasdaq Helsinki") on or about 25 March 2021.

Pekka Eloholma, CEO of Sitowise, comments:

"The interest and excitement around Sitowise's IPO has been impressive, and we are truly thankful for it. We believe that designing sustainable and smart living environments is a business of the future, if any. Based on the feedback we have received, investors seem to share this view. We are especially overwhelmed by the active participation of our employees in the personnel offering. More than 800 Sitowise employees subscribed shares in the personnel offering, which means that more than half of all Sitowise employees are also company shareholders after the listing. The support of our top professionals is a strong basis for taking Sitowise to the next level."

Eero Heliövaara, Chairman of the Board of Directors of Sitowise, comments:

"We are very pleased that the successful IPO will allow us to take important steps in Sitowise's growth story. The listing has aroused great interest. The company will have a strong owner base, consisting of a wide group of international and domestic institutions and hundreds of our employees, among others. As a listed company, Sitowise will be even better equipped to seek further growth in Finland and elsewhere in the Nordics, both organically and through M&A. I would like to extend my gratitude to all our shareholders for the trust you have shown towards Sitowise."

Notwithstanding the assessment of the target market, distributors should note that: the price of the shares may decline and investors could lose all or part of their investment; the shares offer no guaranteed income and no capital protection; and an investment in the shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The target market assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Offering. For the avoidance of doubt, the target market assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the shares in the Company. Each distributor is responsible for undertaking its own target market assessment in respect of the shares in the Company and determining appropriate distribution channels.
