THE SHARES OF THE COMPANY AND THE RIGHT TO VOTE FOR SHARES

Entra ASA is a public limited liability company governed by the Norwegian Public Limited Liability Companies Act. As of the date of this notice, there are 182,132,055 shares issued in Entra ASA, each with a par value of NOK 1. Each share carries one vote at the general meeting and otherwise carries equal rights.

Only those who are shareholders of the Company five business days prior to the general meeting, i.e., on 3 October 2025 (the Record Date), are entitled to attend and vote at the general meeting, cf. section 5-2 (1) of the Norwegian Public Limited Liability Companies Act. A shareholder who wishes to attend and vote at the general meeting must be registered in the shareholder register in the Norwegian Central Securities Depository, Euronext Securities Oslo (VPS), or have reported and documented an acquisition as per 3 October 2025. Shares acquired after 3 October 2025 do not entitle the holder to attend and vote at the general meeting, however, the right to attend and vote is retained for shares sold after 3 October 2025.

SHARES HELD ON NOMINEE ACCOUNTS

In accordance with section 1-8 of the Norwegian Public Limited Liability Companies Act, this notice is sent to nominees who shall pass it on to shareholders for whom they hold shares. On behalf of the beneficial owner, the nominee must, in accordance with section 5-3 of the Norwegian Public Limited Liability Companies Act, register attendance with the Company no later than two business days before the general meeting, i.e., by 8 October 2025 at 23:59 CEST. Beneficial shareholders must themselves communicate with their nominees, who are responsible for conveying votes, proxies or registration of attendance within this deadline.

THE SHAREHOLDERS' RIGHTS

Shareholders, including owners of shares held via nominees and who have registered attendance within the deadline stated above, are entitled to attend the general meeting in person or by proxy. Shareholders have the right to speak and to be accompanied by one advisor, and may give such advisor the right to speak. At the general meeting, shareholders may require that the board members and the CEO provide available information on circumstances that may have an effect on the evaluation of matters that have been put to the shareholders for decision. The same applies to information regarding the Company's financial position and other issues that the general meeting shall deal with, unless the information required cannot be provided without disproportionate harm to the Company.

The deadline for shareholders to put new matters on the agenda has expired, cf. section 5-11 second sentence of the Norwegian Public Limited Liability Companies Act. Shareholders are nevertheless entitled to submit alternatives to the board's proposals under matters to be dealt with by the general meeting, provided that the alternative proposal lies within the scope of a matter on the agenda.
