Circio Holding ASA: Issuance of restricted stock units (RSUs) to the board members

Oslo, 24 September 2026: Reference is made to the extraordinary general meeting of Circio Holding ASA (the "Company") on 25 August 2026 (the "EGM") where the election of new members to the board of directors was made according to the proposal by the nomination committee.

At the annual general meeting on 8 May 2026 (the "AGM"), the board of directors was authorized to extend the Company's restricted stock unit ("RSU") program and to issue RSUs to directors of the board as an alternative to cash compensation. The RSUs are non-transferable and each RSU gives the right and obligation to acquire one share in the Company at a price of NOK 0.60 per share (corresponding to the nominal value of the shares) subject to satisfaction of the applicable vesting conditions.

If the board members choose to receive the board remuneration in RSUs they must elect to either (i) receive 100% of the compensation in RSUs, (ii) receive 1/3 of the compensation in cash and 2/3 in RSUs, or (iii) receive 2/3 of the compensation in cash and 1/3 in RSUs. The number of RSUs is calculated on the basis of an annual board remuneration of NOK 575 000 for the chairperson of the board, NOK 350,000 for other board members and 180,000 for deputy members of the board, divided by the market price of the Company's shares calculated as the volume weighted average share price for the 10 trading days prior to the election date.

* Robert Burns, previously deputy member of the board of directors, was elected as member of the board of directors at the EGM and has resolved to receive 1/3 of the board remuneration, in the form of RSUs and the board of directors has resolved to issue 4,253 RSUs to Robert Burns. The market price is calculated on basis of the EGM date, calculated to NOK 9.3452 per share.

Robert Burns holds 11,074 RSUs, no options and 105,000 shares in the Company.

Please see the attached notifications of trade for information regarding the issuance of RSUs to the primary insiders.
