NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART DIRECTLY OR INDIRECTLY, IN AUSTRALIA, CANADA, JAPAN, HONG KONG OR THE UNITED STATES OR ANY OTHER JURISDICTION IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION WOULD BE UNLAWFUL. THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER OF ANY OF THE SECURITIES DESCRIBED HEREIN.

Trondheim, Norway—22 May 2023—Reference is made to the announcement from CrayoNano AS ("CrayoNano" or the "Company") on 16 May 2023 regarding the board of directors' resolution to carry out a subsequent offering (the "Subsequent Offering") of up to 1,785,714 new shares (the "Offer Shares") following the private placement with gross proceeds approx. NOK 125 million (the "Private Placement").

The subscription period for the Subsequent Offering commences today on 22 May 2023 at 09:00 CEST and will end on 5 June 2023 at 16:30 CEST (the "Subscription Period").

The subscription price per share is NOK 14.00 (the “Subscription Price”), which is equal to the subscription price in the Private Placement. If fully subscribed, the Subsequent Offering will raise gross proceeds of approximately NOK 25 million.

The Subsequent Offering are directed towards existing shareholders in the Company as registered in VPS on 18 April 2023 ("Record Date"), who (i) were not allocated shares in the Private Placement, and (ii) are not resident in jurisdictions where such offering would be unlawful, or (would in jurisdictions other than Norway) require any prospectus, registration or similar action (the "Eligible Shareholders").

Eligible Shareholders are being granted 0.09817 non-tradable subscription rights (the "Subscription Rights") for every share recorded as held in the Company at the Record Date, that, subject to applicable law, provide preferential rights to subscribe for and be allocated Offer Shares in the Subsequent Offering. The total number of Subscription Rights granted to each Eligible Shareholder are rounded down to the nearest whole number of Subscription Rights without compensation to the holder. Each Subscription Right grants the holder a right to subscribe for and be allocated one (1) Offer Share in the Subsequent Offering. Over-subscription will be allowed; however there can be no assurance that Offer Shares will be allocated for such subscriptions. Subscription without Subscription Rights will not be permitted.

The Subscription Rights must be used to subscribe for Offer Shares before the expiry of the Subscription Period on 5 June 2023 at 16.30 hours (CEST). Subscription Rights that are not used to subscribe for Offer Shares before 16:30 (CEST) on 5 June 2023 will have no value and will lapse without compensation to the holder.

In order to subscribe for shares, the Managers (as defined below) must either receive a complete and duly signed subscription form or a subscription through the VPS' solution within the end of the Subscription Period.

Allocation of the Offer Shares is expected on or about 7 June 2023, and the payment for the Offer Shares allocated to a subscriber is expected to fall due on 9 June 2023. The Offer Shares will, after registration of the share capital increase in the Norwegian Register of Business Enterprises pertaining to the Offer Shares, be registered in the VPS in book-entry form and are expected to be delivered to the subscriber's VPS account on or about 30 June 2023, subject to timely payment of the aggregate Subscription Price by the subscriber. The Offer Shares will have equal rights and rank pari passu with the Company's other shares.

The Company reserves the right to withdraw or cancel the Subsequent Offering at any time and for any reason before completion of the Subsequent Offering. If the Subsequent Offering is withdrawn or not carried out, all subscriptions for Offer Shares will be disregarded and any payments for Offer Shares will be returned to the subscribers without interest or any other compensation.

Completion of the Subsequent Offering is subject to (i) all necessary corporate resolutions being validly made by the Company, including the board of directors resolving to allocate the Offer Shares, and (ii) registration of the share capital increase pertaining to the Subsequent Offering with the Norwegian Register of Business Enterprises and delivery of the Offer Shares to the subscribers in the VPS.

A prospectus (the "Prospectus") setting out the terms and conditions for the Subsequent Offering including, inter alia, a description of the Company, material risk factors and subscription procedures, has been prepared and published in connection with the Subsequent Offering. The Prospectus has not been subject to review by the Norwegian Financial Supervisory Authority (Nw. Finanstilsynet) nor any other authority, but is registered with the Norwegian Register of Business Enterprises (Nw. Foretaksregisteret) in accordance with section 7-8 of the Norwegian Securities Trading Act.

The Prospectus is available at the Managers' websites www.dnb.no/emisjoner and www.sb1markets.no/transaksjoner/.

DNB Markets, a part of DNB Bank ASA and SpareBank 1 Markets AS are acting as managers for the Subsequent Offering (the "Managers"). Advokatfirmaet Wiersholm is acting as legal counsel to CrayoNano.
