The Board of Directors’ proposals for resolutions

Item 2: Election of Chairman of the Meeting

The board of directors proposes that Thomas Eldered, 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.

Item 7. Resolution on merger with Biosergen AB

In order to implement the proposed merger between Flerie and Biosergen AB (“Biosergen” and the “Merger”), the board of directors proposes that the meeting resolves to approve the merger plan and authorisation for the board of directors to resolve on new issues of ordinary shares in accordance with items 7 (a)–7 (b) below.

The resolutions under items 7 (a)–7 (b) below are conditional upon each other and upon the Swedish Companies Registration Office’s registration of the Merger.

Item 7 (a). Approval of the merger plan

The board of directors proposes that the meeting resolves to approve the merger plan, dated 26 June 2026, which has been jointly adopted by the boards of directors of Flerie and Biosergen (the “Merger Plan”). The Merger Plan was registered with the Swedish Companies Registration Office on 30 June 2026 and announced on 2 July 2026. According to the Merger Plan, the Merger shall be undertaken by way of absorption, with Flerie as the absorbing company and Biosergen as the transferring company. Following the completion of the Merger, Biosergen’s operations will be contributed to a new subsidiary of Flerie’s wholly owned subsidiary Flerie Invest AB. According to the Merger Plan, the exchange ratio for the merger consideration has been determined in such a way that thirty-one (31) shares in Biosergen shall be exchanged for one (1) new ordinary share in Flerie (the “Merger Consideration”). Registration of the Merger with the Swedish Companies Registration Office is conditional upon the conditions in the Merger Plan, inter alia that the extraordinary general meetings of both Flerie and Biosergen approve the Merger Plan. The Merger is expected to be registered with the Swedish Companies Registration Office during the last quarter of 2026 and will result in the dissolution of Biosergen, whereby all of Biosergen’s assets and liabilities will be transferred to Flerie. Settlement of the Merger Consideration will take place following the Swedish Companies Registration Office registration of the Merger.

Item 7 (b). authorisation for the board of directors to resolve on new issues of ordinary shares

The board of directors proposes that the extraordinary general meeting authorise 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 ordinary shares to be paid as Merger Consideration to the shareholders of Biosergen 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 to the shareholders of Biosergen 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 of the resolution with the Swedish Companies Registration Office.

Special majority Requirements

For valid resolutions under items 7 (a)–(b), the proposals must be supported by shareholders representing at least two-thirds of both the votes cast and the shares represented at the meeting.

Number of shares and votes in the company

As of 30 June 2026, there are a total of 86,697,702 shares in the Company, all of which are ordinary shares, representing the same number of votes. There are no shares issued of series C. The Company does not own any of its own shares.

Shareholders' right to request information

Pursuant to Chapter 7, Section 32 of the Swedish Companies Act, the board of directors and the CEO shall, if requested by any shareholder and if the board of directors considers that it can be done without significant harm to the Company, provide information at the meeting regarding matters that may affect the assessment of an item on the agenda. The duty to provide information also covers the Company’s relationship with other group companies, the consolidated financial statements, and such matters concerning subsidiaries as referred to in the preceding sentence.
