Bergen, 29 October 2025: M Vest Water AS (“M Vest Water” or the "Company") has decided to effect a private placement (the "Private Placement") of new shares in the Company (the "Offer Shares") to raise gross proceeds of approximately NOK 8 million (which amount may be increased at the sole discretion of the Board if desirable to meet investor interest or otherwise) (the "Offer Size"). The subscription price per Offer Share is NOK 8 (the "Offer Price"), which implies a premium to the 30 trading day VWAP for the shares in the Company, which (unless the amount of the Private Placement is increased by the Board) will result in 1,000,000 Offer Shares being issued within the Offer Size. The Private Placement will, pursuant to an Underwriting Agreement (as defined below), be underwritten by M Vest Invest AS and Haugland Gruppen AS (the "Underwriters") up to a total underwriting obligation of NOK 8 million (the "Total Underwriting Obligation"). The final number of Offer Shares issued in the Private Placement will be determined by the Company's board of directors (the "Board"). In combination with the Private Placement, the Company has agreed with two of its shareholders to convert their outstanding shareholder loan amounting to NOK 12 million plus interest of NOK 622,688 to new shares in the Company, at a price per new share equal to the Offer Price (the "Conversion").

The net proceeds from the Private Placement will be employed as working capital in the Company and will be used to finance the Company’s ongoing projects and tender activities. The proceeds are expected to provide adequate funding for the Company’s current ongoing projects and tenders. As earlier released in the Q2 earnings call the Company experiences high activity and demand for its NORWAFLOC® products across all the Company's segments and the net proceeds will be employed to meet this demand in working capital.

The Company's business segment Aquaculture is profitable due to increased sales, and we expect the positive trend in recurring revenues from this segment to continue into the following periods. The Company's dredging operations in Germany is developing according to plan and we have a strong and growing tender portfolio in both dredging and oil & gas in the Middle East, which represents significant growth opportunities for the Company's NORWAFLOC® and NORWAPOL® products.

The Private Placement will be directed towards selected domestic investors, in each case subject to and in compliance with applicable exemptions from relevant prospectus, filing and other registration requirements.

Pre-commitment and underwriting
Pursuant to, and subject to the terms and conditions of the underwriting agreement between the Company and the Underwriters (the "Underwriting Agreement"), the Underwriters have undertaken on a pro-rata basis (not jointly) to underwrite an aggregate subscription amount in the Private Placement up to the Total Underwriting Obligation). The Underwriters will not be entitled to any underwriting fee. Each Underwriter has undertaken to take all and any step required to give effect to the Conversion.

The application period for the Private Placement commences today, 29 October 2025, at 16:30 CET and closes on 30 October 2025 at 08:00 CET (the "Application Period"). The Company reserves the right to shorten, close or extend the Application Period at any time and for any reason on short, or without notice. If the Application Period is shortened or extended, the other dates referred to herein may be changed accordingly.

The minimum order size and allocation in the Private Placement will be the NOK equivalent of EUR 100,000, provided that the Company may, at its sole discretion, allocate Offer Shares for an amount below the NOK equivalent of EUR 100,000 to the extent applicable exemptions from the prospectus requirements pursuant to the Norwegian Securities Trading Act and ancillary regulations (including Regulation (EU) 2017/1129) are available. Further selling restrictions and transaction terms will apply. The Private Placement is, for the avoidance of doubt, solely directed towards investors subject to, and in compliance with, applicable exemptions from relevant prospectus or registration requirements.

Allocation and settlement

Allocation of Offer Shares will be made at the sole discretion of the Board after expiry of the Application Period (subject to any shortening or extension), focusing on criteria such as (but not limited to) pre-commitments, existing ownership in the Company, timeliness of the application, relative order size, sector knowledge, perceived investor quality and investment horizon. Notifications of allocations are expected to be distributed to applicants on or about 30 October 2025.

The Offer Shares will be issued pursuant to the authorization granted to the Board by the Company's annual general meeting on 27 March 2025 (the "Board Authorization").

Settlement of the Offer Shares is expected to take place on 4 November 2025. The Offer Shares will be delivered to applicants and will be tradable on Euronext Growth Oslo as soon as possible after the share capital increase related to the Private Placement has been registered with the Norwegian Register of Business Enterprises and the Offer Shares have been issued in Euronext Securities Oslo ("VPS").

Completion of the Private Placement is subject to a resolution by the Board to consummate the Private Placement, including to allocate the Offer Shares and issue the Offer Shares pursuant to the Board Authorization. The Company, reserves the right, at any time and for any reason, to cancel, and/or modify the terms of, the Private Placement prior to notification of allocation of Offer Shares. Neither the Company or any of their respective directors, officers, employees, representatives or advisors, will be liable for any losses if the Private Placement is cancelled and/or modified, irrespective of the reason for such cancellation of modification.

Equal treatment considerations

The Private Placement and the Conversion represents a deviation from the shareholders' pre-emptive right to subscribe for the Offer Shares. The Board has considered the Private Placement in light of the equal treatment obligations under the Norwegian Public Limited Companies Act, the Norwegian Securities Trading Act, the rules on equal treatment under Oslo Rule Book II for companies listed on the Oslo Stock Exchange, and guidelines on the rule of equal treatment from Oslo Stock Exchange and the Financial Supervisory Authority of Norway, at the latest the thematic review published on 19 December 2023, and deems that the proposed Private Placement is in compliance with these obligations. The Board is of the view that it will be in the common interest of the Company and its shareholders to raise equity through a private placement, in particularly considering that the Company has been able to raise equity at a subscription price which exceeds the recent traded price, at a lower cost and with a significantly reduced completion risk compared to a rights issue.
