1. on the record date, which is Monday 9 March 2026, be registered in the share register maintained by Euroclear Sweden AB (for nominee registered shares, also see below under the heading “Nominee registered shares”); and
2. notify the Company of their participation and any assistants (no more than two) in the general meeting no later than Wednesday 11 March 2026.

Nominee registered shares
Shareholders, whose shares are registered in the name of a bank or other nominee, must temporarily register their shares in their own name with Euroclear Sweden AB in order to be entitled to participate in the general meeting. Such registration (so-called voting rights registration), which normally is processed in a few days, must be completed no later than on Monday 9 March 2026 and should therefore be requested from the nominee well before this date. Voting registration requested by a shareholder in such time that the registration has been made by the relevant nominee no later than on Wednesday 11 March 2026 will be considered in preparations of the share register.

Proxy etc.
A shareholder who wishes to be represented by proxy shall issue a written and dated proxy to the proxy holder. If the proxy is issued by a legal entity, a certified copy of the registration certificate or corresponding document ("Registration Certificate") shall be enclosed. The proxy must not be more than one year old, however, the proxy may be older if it is stated that it is valid for a longer term, maximum five years. The proxy in original and the Registration Certificate, if any, must be available at the general meeting and a copy should well before the meeting be sent to the Company by regular mail or by e-mail to the address above and should, in order to facilitate the entrance to the general meeting, be at the Company's disposal no later than on Wednesday 11 March 2026.

A form proxy will be available on the Company's website www.soltechenergy.com.

Proposition for resolution

Item 1: Opening of the meeting and election of chairman of the meeting
The nomination committee proposes that Carl Svernlöv, attorney at law, Baker McKenzie, is appointed as chairman of the extra general meeting.

Item 6: Determination of the number of board directors, board remuneration, election of the board of directors and election of chairman to the board
The nomination committee proposes that the board of directors shall consist of six directors.

The nomination committee does not propose any changes to the board fees resolved by the annual general meeting 2025, which shall remain unchanged. Fees to the newly elected board members, should they be elected, shall therefore be paid in the same amount, pro rata for the term of office until the next annual general meeting.

The nomination committee proposes the election of Petteri Saarinen and Joachim Zetterlund as new board members, and that Ivana Stankovic and Bernt Ingman resign from their duties on the board. Furthermore, it is proposed that Petteri Saarinen be elected as chairman of the board.

The nomination committee also proposes that Stefan Ölander, Ove Anebygd, Jacob Langhard-Rosencrantz and Thomas Mejdell remain as board members.

If the extra general meeting resolves in accordance with the submitted proposals, Nordic Capital and Stefan Ölander have agreed that the 18‑month lock‑up undertaking provided by Stefan Ölander to Nordic Capital in connection with the divestment of Sesol and the completion of the rights issue, as communicated on 4 July 2025, shall be terminated.
