Payment information for OSE, LSE and certificated shareholders

OSE shareholders

Shareholders of GKP shares trading on Euronext Growth Oslo operated by the Oslo
Stock Exchange (“OSE”) will receive the interim dividend in NOK. The Company
will announce the NOK per share amount on 22 April 2026.

LSE shareholders holding CREST Depositary Interests

On or around 1 April 2026, cross border transfers will be implemented between
the London Stock Exchange (“LSE”) and the OSE. As part of this process, the
existing Depositary Interests currently used for settlement of trades on the LSE
will be cancelled and will be replaced by CREST Depositary Interests (CDIs)
issued by Euroclear UK & International Limited (“Euroclear”). The CDIs will be
held in a Euroclear nominee account registered in the Norwegian VPS.

The interim dividend will be paid to the Euroclear nominee account in NOK, as
per the conventions of the Norwegian VPS and according to the NOK per share
amount announced on 22 April 2026. CDI holders will in turn receive the dividend
in EUR, GBP or USD according to the preferred payment currency of their CREST
account.

Where a CREST participant has not explicitly set a preferred CREST currency, the
system will follow alphabetical order of eligible currencies as set out in the
Euroclear International Service Description. This means payment would default to
EUR (if the participant can receive EUR), or GBP if not, and finally USD if no
EUR or GBP payment account is linked to the CREST account. Shareholders are
encouraged to contact their broker or nominee account to confirm their final
payment currency for the interim dividend.

Certificated shareholders

Certificated shareholders will continue to receive the interim dividend in
either GBP or USD according to their currency election preference.

The default currency for the Company’s dividend payments to certificated
shareholders is GBP, either via cheque or BACS. Dividend payments in USD can be
paid by cheque only. Should certificated shareholders wish to change their
current currency to USD or modify their payment methods, forms are available
through Computershare Investor Services PLC at the following link:

The final day for currency election for certificated shareholders will be 13
April 2026. Certificated shareholders who have previously amended their
preferences are not required to do so again, unless they wish to make further
changes.
