Stockholm, 29 December, 2021

Carnegie Investment Bank AB (publ) (“Carnegie”) has undertaken stabilisation measures in Devyser Diagnostics AB (publ)’s (“Devyser” or the “Company”) shares on Nasdaq First North Premier Growth Market (“First North”).

As announced on 1 December 2021 in connection with the listing of the Company's shares on First North and the offering of shares made in connection thereto (the “Offering”), Carnegie may, as Sole Global Coordinator and Sole Bookrunner, carry out transactions aimed at supporting the market price of the Company’s share at levels above those which might otherwise prevail in the open market.

Stabilisation transactions may be undertaken on First North, in the over-the-counter market or otherwise, at any time from the first day of trading in the shares on First North, i.e. 10 December 2021, and for no longer than 30 calendar days thereafter. Carnegie is, however, not required to undertake any stabilisation and there is no assurance that stabilisation will be undertaken. Stabilisation, if undertaken, may be discontinued at any time without prior notice. In no event will transactions be executed at levels above the price in the Offering.

To cover any over-allotments related to the Offering, the Company granted Carnegie an option to issue an additional 625,000 shares, corresponding to approximately 14.6 percent of the total number of shares in the Offering prior to any over-allotments (the “Over-allotment Option”).
