INDIRECTLY, IN AUSTRALIA, CANADA, JAPAN, HONG KONG, SOUTH AFRICA OR THE UNITED

DISTRIBUTION WOULD BE UNLAWFUL. THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER

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.
