(Arendal, Norway / Sherbrooke QC, Canada - 18 November 2025)

Reference is made to the previous stock exchange announcements by Tekna Holding
ASA (the "Company") regarding the fully underwritten rights issue of 100,000,000
new shares in the Company (the "Offer Shares"), at a subscription price of NOK
3.00 per share (the "Subscription Price"), to raise gross proceeds of NOK 300
million (the "Rights Issue").

The terms and conditions of the Rights Issue are set out in a prospectus
prepared by the Company dated 14 November 2025 (the "Prospectus"). Subject to
local applicable securities laws, the Prospectus is made available at the
website of Arctic Securities AS (the "Manager")
(https://www.arctic.com/offerings).

The subscription period for the Rights Issue will commence today, 18 November
2025, at 09:00 hours (CET) and expire on 2 December 2025 at 16:30 hours (CET).
The Subscription Rights (as defined below) in the Rights Issue will be tradable
on Euronext Oslo Børs under the ticker code "TEKNT" from today, 18 November 2025
at 09:00 hours (CET) until 26 November 2025 at 16.30 hours (CET). The
Subscription Rights will hence only be tradable during a part of the
Subscription Period.

Subscription Rights: Shareholders of the Company's shares as of 13 November 2025
(as registered in the Company's shareholder register in the Norwegian Central
Securities Depository as of 17 November, (the "Record Date" and such
shareholders the "Existing Shareholders")), have been granted tradable
subscription rights (the "Subscription Rights") in the Rights Issue that,
subject to applicable law, provide preferential rights to subscribe for and be
allocated Offer Shares.

Each Existing Shareholder has been granted 0.7845 Subscription Rights for every
one (1) existing share in the Company registered as held by the Existing
Shareholder as 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) Offer Share in the
Rights Issue. Over-subscription with Subscription Rights and subscription
without Subscription Rights are 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 13 "Selling and Transfer Restrictions" of the Prospectus.

Subscription Rights that are not exercised to subscribe for Offer Shares before
the end of the Subscription Period on 2 December at 16:30 hours (CET), or that
are not sold before 16:30 hours (CET) on 26 November 2025, will have no value
and lapse without compensation to the holder. 

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 5.9
"Subscription Rights" and Section 5.20 "Dilution" in the Prospectus for further
information. 

Underwriting: An Existing Shareholder has, on the terms and conditions set out
in a separate underwriting agreement, undertaken to fully underwrite the Rights
Issue, i.e. with an aggregate amount of up to NOK 300 million. Pursuant to the
underwriting agreement, the underwriter has undertaken to subscribe and pay for
unsubscribed Offer Shares, see Section 5.21 "The Underwriting" of the
Prospectus. 

Payment, delivery and commencement of trading: The payment date in the Rights
Issue is 5 December 2025. Subject to timely payment of the Offer Shares
subscribed for and allocated in the Rights Issue, the issuance and delivery of
the Offer Shares is expected to be completed on or about 11 December 2025. The
Offer Shares are expected to commence trading on Euronext Oslo Børs on 11
December 2025.

Arctic Securities AS is acting as manager for the Rights Issue. Advokatfirmaet
Wiersholm AS is acting as legal advisor to the Company in connection with the
Rights Issue.

This information is subject to disclosure requirements pursuant to section 5-12
of the Norwegian Securities Trading Act.
