Sandnes, Norway, 21 August 2025: Desert Control AS (the "Company") hereby announces a fully underwritten rights issue with preferential subscription rights (the "Subscription Rights") for the Company's existing shareholders as at the close of trading on the day of the EGM (as defined below) to raise gross proceeds of NOK 75 million, which pursuant to certain Underwriting Agreements (as defined below) will be fully underwritten by a consortium of underwriters comprising of certain larger existing shareholders in the Company and new investors (the "Underwriters") (the "Rights Issue").

The net proceeds from the Rights Issue will be used to extend cash run-way through approx.12 - 16 months following completion of the Rights Issue, covering core operations, working capital and further investments in production units and sales teams, as well as other general corporate purposes.

The proposed Rights Issue is subject to, inter alia, approval by the Company's shareholders at an extraordinary general meeting in the Company (the "EGM"), expected to be held on 5 September 2025. The notice of the extraordinary general meeting is expected to be sent to shareholders on 22 August 2025 and will be published in a separate stock exchange announcement.

Arctic Securities AS has been engaged as manager and bookrunner (the "Manager") for the Rights Issue.

The Rights Issue is subject to the following conditions (together, the "Conditions"): (i) the EGM approving the Rights Issue, (ii) the Company having published a national prospectus (the "Prospectus") as registered in the Norwegian Register of Business Enterprises ("NRBE") and (iii) that the Underwriting Agreements (as defined below) remaining in full force and effect. The record date for the Rights Issue will be the second trading date after the EGM, expected to be on 9 September 2025 (the "Record Date").

Each shareholder will be granted Subscription Rights in proportion to the number of existing shares registered in the Company's shareholder register as at the Record Date, cf. section 10-4 of the Norwegian Private Limited Liability Companies Act. Each Subscription Right will, subject to applicable securities laws, give the right to subscribe for and be allocated one new share in the Company (the "Offer Shares"). Provided that a purchase of shares is made with ordinary T+2 settlement, shares purchased up to and including 5 September 2025 will give the right to receive subscription rights, whereas shares purchased from and including 8 September 2025, will not give the right to receive subscription rights. The subscription rights will be tradable and sought listed on the Euronext Growth Oslo ("EGO") from and including the first day of the subscription period and until 16:30 (Oslo time) four trading days prior to the expiry of the subscription period. Oversubscription with subscription rights and subscriptions by the Underwriters will be allowed. Other subscription without Subscription Rights will not be permitted.

The subscription price for the new shares to be issued in the Rights Issue, and thus the exact number of Offer Shares and the exact amount of the share capital increase, will be proposed by the board of directors, based on a recommendation from the Manager, the day prior to the EGM. The subscription price in the Rights Issue (the "Subscription Price") shall pursuant to the Underwriting Agreements (as defined below) be the theoretical share price exclusive of the subscription rights (TERP) based on the volume-weighted average price (VWAP) of the Company's shares on EGO on the three last trading days prior to the date of the EGM less a discount of at least 32.5%. The board of directors' resolution in this respect will be announced through a stock exchange announcement on the day prior to the EGM and be reflected in the final proposed resolution to the EGM.

It is contemplated that the Rights Issue will be conducted with a two-weeks subscription period, commencing on the first or second trading date after the Record Date, subject to satisfaction of the Conditions for the Rights Issue.

All dates and other figures with respect to the Rights Issue included herein remain tentative and subject to change.

Any changes will be announced at the EGM or through stock exchange announcements.

Underwriting

Pursuant to, and subject to the terms and conditions of the underwriting agreements between the Company and 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 New 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).

Each Underwriter has undertaken to vote in favor of the resolutions required to complete the Rights Issue, provided that it is a shareholder in the Company at the date of the EGM.

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. Furthermore, the Underwriters include the existing shareholders:

• Handelsbanken Fonder AB, which have committed to underwrite for NOK 5,497,500
• LIN AS, which have committed to underwrite for NOK 2,100,000
• Glomar AS, which have committed to underwrite for NOK 3,825,000
• Olesen Consult Hvac AS, which have committed to underwrite for NOK 100,000
• Sancta Capital, which have committed to underwrite for NOK 7,500,000
• Jacob Hatteland Holding AS, which have committed to underwrite for NOK 1,700,000
• Sortun Invest AS, which have committed to underwrite for NOK 2,010,000
• OKS Consulting AS, which have committed to underwrite for NOK 100,000

New investors have committed to underwrite for a total of NOK 37,167,500 million.

Allocation

The allocation principles for the Offer Shares in the Rights Issue will be set out in the EGM resolution and in the Prospectus, but are expected to be as set out below

a)           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.

b)           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.

c)            Thirdly, Offer Shares not allocated pursuant to a) -b) 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.

d)           Finally, Offer Shares not allocated pursuant to paragraph a) - c) 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.

The final allocation principles resolved by the EGM and set out in the Prospectus may deviate from those set out above.
