B2Holding ASA (the "Company") has decided to initiate a one-off share buy-back offer. The Company intends to carry out a one-off share buy-back of up to 10 million shares, conducted by placing a single buy order in the market for a total amount of 10 million shares at market opening on 27 June 2023 at NOK 6,60 corresponding to the volume weighted average price on 26 June 2023. The order is valid until end of trading on 28 June 2023 or until the order is filled. All shareholders in the Company are invited to sell shares, and the order will be allocated on a first-come first-serve basis. This offer will be conducted in accordance with the authorization provided by the Annual General Meeting to the Board of Directors on 25 May 2023, and is independent of the Company’s ongoing share buy-back programme announced earlier this year. The purpose of the offer is to cancel the shares acquired in the offer. This offer is made in addition to the ongoing “Safe Harbour” share buyback program managed by Nordea Markets, and the share buyback program will be paused as long as the order is valid, i.e. until the end of trading on 28 June 2023 or until the order is filled. The share buyback program will commence again thereafter without further notice. The one-off order will be placed through Nordea Markets.
