THE BOARD OF DIRECTORS’ PROPOSALS FOR RESOLUTIONS

Item 2. Election of chairman of the meeting

The board of directors proposes that Peter Rejler, chairman of the board of directors, or, in the event of his unavailability, any individual proposed by the board of directors to serve in his stead, be elected as chairman of the meeting.

Items 7–12. Resolutions regarding the proposed Merger

To implement the proposed cross-border merger (the “Merger”) between Rejlers and Multiconsult ASA (“Multiconsult”), the board of directors proposes that the meeting adopts the resolutions under items 7–10 and, in accordance with the nomination committee’s proposals, under items 11–12 below on approval of the merger plan jointly adopted by the boards of directors of Rejlers and Multiconsult (the “Merger Plan”), amendment of the articles of association and authorisation for the board of directors to resolve on an issue of newly issued class B shares that constitute the merger consideration (the “Merger Consideration”).

The resolutions under items 8–12 are conditional upon each other. The resolutions under items 8, 9, 11 and 12 are also conditional upon registration of the Merger with the Swedish Companies Registration Office. Registration of the Merger with the Swedish Companies Registration Office is subject to the conditions of the Merger Plan being satisfied, inter alia that the general meetings of both companies have approved the Merger Plan and that the requisite permits, approvals, decisions and other measures from authorities and similar have been obtained.

Item 7. Resolution on amendment of the articles of association (share capital limits, limits on the number of shares and collection of proxies and postal voting)

The board of directors proposes that the limits for the share capital and the number of shares in Sections 4 and 5 of the articles of association be amended and that a new Section 14 be introduced as set out below.

Item 8. Approval of the Merger Plan

The board of directors proposes that the meeting resolves to approve the Merger Plan, dated and executed on 7 September 2026, which has been jointly adopted by the boards of directors of Rejlers and Multiconsult. The Merger Plan was registered with the Swedish Companies Registration Office on 11 September 2026 and notice thereof was published on 15 September 2026.

The Merger is a cross-border merger pursuant to Chapter 23, Section 36 of the Swedish Companies Act and Chapter 13, Part VII of the Norwegian Public Limited Liability Companies Act and shall be undertaken by way of absorption, with Rejlers as the transferee company and Multiconsult as the transferring company. Multiconsult shall be dissolved without liquidation and all assets, rights and liabilities shall be transferred to Rejlers by universal succession upon completion of the Merger. The combined company shall be named Multiconsult Rejlers AB (publ).

The exchange ratio entails that each share in Multiconsult entitles the holder to receive 0.9725 new class B shares in Rejlers, corresponding to 389 new class B shares in Rejlers for every 400 shares in Multiconsult (subject to an adjustment mechanism as described in the Merger Plan).

Settlement of the Merger Consideration shall take place following the Swedish Companies Registration Office’s registration of the Merger.

Item 9. Resolution on amendment of the articles of association (company name)

The board of directors proposes that the meeting resolves to amend Section 1 of the articles of association as set out below, whereby the Company’s company name shall be changed to Multiconsult Rejlers AB (publ).

The resolution on amendment of the articles of association is conditional upon the Swedish Companies Registration Office registering the Merger and shall be registered in connection therewith. The board of directors, the CEO or any person appointed by the board of directors shall have the right to make such minor adjustments as may prove necessary in connection with registration with the Swedish Companies Registration Office.

Item 10. Authorisation for the board of directors to resolve on a new issue of shares to pay the Merger Consideration

The board of directors proposes that the meeting authorises the board of directors to, on one or more occasions during the period until the next annual general meeting, with deviation from the shareholders' preferential rights, resolve on a new issue of class B shares to be paid as Merger Consideration to the shareholders of Multiconsult in accordance with the Merger Plan.

The purpose of the authorisation, and the reason for the deviation from the shareholders' preferential rights, is to enable the payment of the Merger Consideration in accordance with the Merger Plan.

The use of an authorisation, instead of an issue resolution adopted directly by the general meeting, constitutes such a minor amendment in relation to the Merger Plan as the chairman of the board of directors of Rejlers and the chairman of the board of directors of Multiconsult may jointly resolve upon pursuant to the amendment clause of the Merger Plan. The amendment is not detrimental to the shareholders, since the Merger Consideration is provided on unchanged terms in accordance with the Merger Plan.

The board of directors, or any person appointed by the board of directors, shall be authorised to make such minor adjustments to the resolution as may be required for the registration with the Swedish Companies Registration Office.

THE NOMINATION COMMITTEE'S PROPOSALS FOR RESOLUTIONS

Item 11. Resolution on the number of board members, remuneration and election of the board of directors

The nomination committee will, no later than in connection with the meeting, submit its proposals under item 11.

A short presentation of the proposed members and the nomination committee’s reasoned statement will be made available on the Company’s website www.rejlers.com no later than in connection with the meeting.

Item 12. Resolution on temporary amendment of the instruction for the nomination committee

The nomination committee proposes that the meeting resolves on a temporary amendment of the instruction for the nomination committee, entailing that the nomination committee which shall prepare proposals for the annual general meeting 2027 shall, with effect from registration of the Merger with the Swedish Companies Registration Office, consist of three members: Arnor Jensen, representing Stiftelsen Multiconsult, who shall be the chairman of the nomination committee, Lisa Rejler, who is the chairman of Rejlers’ current nomination committee and represents the Rejler family, and one member appointed by the third largest shareholder in the combined company following the registration of the Merger, counted after the Rejler family and Stiftelsen Multiconsult. The composition is based on the ownership in the Company immediately following the registration of the Merger with the Swedish Companies Registration Office. The amendment applies only to the nomination committee ahead of the annual general meeting 2027. Thereafter, the instruction continues to apply in its ordinary wording.

SPECIAL MAJORITY REQUIREMENTS AND VOTING UNDERTAKINGS

For valid resolutions under items 7–10, it is required that the proposals are supported by shareholders representing at least two-thirds (2/3) of both the votes cast and the shares represented at the meeting. In respect of item 8, this majority requirement shall apply separately to each class of shares represented at the general meeting.

Pre-acceptances and undertakings to vote in favour of the Merger Plan have been obtained from members of the Rejler family (including Jangunnar AB), Lauri Valkonen, and certain of the other shareholder-elected directors and members of the executive management, representing in aggregate approximately 18 per cent of the share capital and approximately 51 per cent of the votes in Rejlers.

NUMBER OF SHARES AND VOTES IN THE COMPANY

As at the date of this notice, the number of shares in the Company amounts to 22,835,567, of which 1,749,250 are Class A shares and 21,086,317 are Class B shares, and the number of votes in the Company amounts to a total of 38,578,817.
