Reference is further made to the stock exchange announcement published by the Company on 9 September 2025 regarding the publication of a national prospectus prepared in connection with the Rights Issue (the "Prospectus") as registered in the Norwegian Register of Business Enterprises ("NRBE").

The subscription period for the Rights Issue will commence today, 10 September 2025 at 09:00 hours (CEST) and expire on 24 September 2025 at 16:30 hours (CEST) (the "Subscription Period"). The Subscription Rights (as defined below) will be tradable on Euronext Growth Oslo under the ticker code (DSRTT) from today, 10 September 2025 at 09:00 hours (CEST) until 18 September 2025 at 16:30 hours (CEST).

Allocation of Subscription Rights:

Shareholders of the Company as of 5 September 2025 (and being registered as such in Euronext Securities Oslo, the Norwegian Central Securities Depository (the "VPS") as of 9 September 2025 pursuant to the two days' settlement procedure (the "Record Date", and such shareholders, the "Existing Shareholders"), have been granted tradable subscription rights (the "Subscription Rights") in the Rights Issue.

Each Existing Shareholder has been granted 1.130154 Subscription Rights for each existing share in the Company registered as held by the Existing Shareholder of the Record Date, rounded down to the nearest whole Subscription Right. Each Subscription Right will, subject to applicable law, give the right to subscribe for, and be allocated one (1) new share at the Subscription Price. Oversubscription with subscription rights and subscriptions by the Underwriters (as defined below) will be allowed. Other subscriptions without Subscription Rights will not be permitted.

The allocation to, or acquisition of Subscription Rights by, and the subscription of Offer Shares by, persons resident in, or who are citizens of countries other than Norway, may be affected by the laws of the relevant jurisdiction. For a further description of such restrictions, reference is made to Section 5.20 "Selling and Transfer Restrictions" of the Prospectus.

The Subscription Rights:

The Subscription Rights will be tradable and listed on Euronext Growth Oslo from 09:00 hours (CEST) on 10 September 2025 to 16:30 hours (CEST) on 18 September 2025 under the ticker code "DSRTT". The Subscription Rights will hence only be tradable during a part of the Subscription Period.

Subscription Rights that are (i) not sold before 16:30 hours (CEST) on 18 September 2025 or (ii) not used to subscribe for shares in the Rights Issue prior to expiry of the Subscription Period on 24 September 2025 at 16:30 hours (CEST) will lapse without compensation to the holder, and thus be without value.

The Subscription Rights are expected to have an economic value if the Company's shares trade above the Subscription Price during the Subscription Period. Existing Shareholders who do not exercise their Subscription Rights will experience a dilution of their shareholding in the Company. See Section 5.10 "Subscription Rights" for further information about the Subscription Rights.

Underwriting:

Pursuant to, and subject to the terms and conditions of the underwriting agreements entered into between the Company and the underwriters (the "Underwriters") (the "Underwriting Agreements"), the Underwriters have undertaken on a pro-rata basis (not jointly) to underwrite an aggregate subscription amount in the Rights Issue of NOK 75 million (the "Total Underwriting Obligation"). Any Offer Shares subscribed in the Rights Issue will reduce the underwriting commitment of the Underwriters.

Each of the Underwriters are entitled to an underwriting fee of either (i) 10% of the underwriting obligation if received as a payment in cash or (ii) 12% of the underwriting obligation if received as new shares in the Company issued at the same Subscription Price as in the Rights Issue, which is payable upon completion of the Rights Issue (i.e. upon registration of the share capital increase pertaining to the Rights Issue with the NRBE).

Among the Underwriters is Woods End Interests LLC, the Company's largest shareholder and a closely associated company with the Company's CEO, which has committed to underwrite for NOK 15 million.

Allocation:

The allocation principles for the Offer Shares in the Rights are as set out below.

1. Firstly, allocation of Offer Shares to subscribers will be made in accordance with granted and acquired Subscription Rights which have been validly exercised during the Subscription Period. Each Subscription Right will give the right to subscribe and be allocated one Offer Share in the Rights Issue.

1. Secondly, if not all Subscription Rights are validly exercised during the Subscription Period and there are remaining unallocated Offer Shares following the allocation pursuant to paragraph a) above, subscribers who have exercised their Subscription Rights and over-subscribed, will be allocated additional Offer Shares on a pro rata basis based on the number of Subscription Rights exercised by each subscriber. To the extent that pro rata allocation is not possible, the Company will determine the allocation by drawing of lots.

1. Thirdly, Offer Shares not allocated pursuant to (i) - (ii) above, will be allocated to Underwriters who have subscribed for Offer Shares in excess of their respective underwriting obligation. Allocation will be sought made on a pro rata basis based on such Underwriters' oversubscription.

1. Finally, Offer Shares not allocated pursuant to paragraph (i) - (iii) above, will be allocated to and subscribed by the Underwriters pursuant to, and in accordance with, each Underwriter's underwriting obligation pursuant to the terms and conditions of Underwriting Agreements.
