Business to be conducted at the Meeting

Ordinary Business

Resolutions 1 to 3 deal with ordinary business.

Resolution 1 – Annual Report and Financial Statements

Resolution 1 relates to reviewing the Company's affairs and considering the Company's Financial Statements for the year ended 31 December 2021.

Resolution 2 – Continuation of statutory auditor

Resolution 2 relates to the continuation of Mazars as statutory auditor of the Company.

Resolution 3 – Remuneration of statutory auditor

Resolution 3 relates to the authority of the Directors to determine the remuneration of the statutory auditor.

Special Business

In addition to the ordinary business to be transacted at the Meeting, there are two items of special business which are described further below.

Resolution 4 – Authority to Make Market Purchases of the Company's Ordinary Shares

Under Resolution 4, shareholders are being asked to give the Company and/or any of its subsidiaries authority to make market purchases of up to 10% of the Company's Ordinary Shares.

The Directors monitor the Company's share price and may from time to time exercise this power to make market purchases of the Company's Ordinary Shares, at price levels which they consider to be in the best interests of the shareholders generally, after taking account of the Company's overall financial position. The minimum price which may be paid for any market purchase of the Company's Ordinary Shares will be the nominal value of the shares and the maximum price which may be paid will be the greater of (i) 105% of the average market price of such shares for the previous five days and (ii) the higher of the price quoted for the last independent trade and the highest current independent bid or offer for such shares. The power under this Resolution will expire at next year's annual general meeting or 15 months after the forthcoming Meeting, whichever is the earlier.

Resolution 5 - Authority to Re-issue Treasury Shares

Shareholders are being asked to sanction the price range at which any treasury share (that is a share of the Company redeemed or purchased and held by the Company rather than being cancelled) may be re-issued other than on a stock exchange. The maximum and minimum prices at which such a share may be re-issued are 120% and 95%, respectively of the appropriate price of a share calculated over the five business days immediately preceding the date of such re-issue as detailed further in the Notice. If adopted, the authority under this

Resolution will expire at next year's annual general meeting or 15 months after the forthcoming Meeting, whichever is the earlier.

The foregoing Resolutions 1 – 5 are together the "Resolutions".

Voting

Details on how you can vote are set out in notes 3 to 21 in the Notes to the Notice.

Recommendation

The Board of Directors believes that the Resolutions are in the best interests of the Company and its shareholders as a whole and, therefore, unanimously recommends that you vote in favour of each of the Resolutions, as they intend to do so themselves in respect of all of the 7,571,764 Shares (representing approximately 28.8% of the issued ordinary share capital of the Company on 23 August 2022 held or beneficially owned by them).

Shareholders should monitor the Company's website, https://alternusenergy.com/reportspresentations// for any update announcements regarding the arrangements for the Meeting.

Yours faithfully,

Vincent Browne

Chairman and CEO

For the purposes of this Resolution the expression "appropriate price" shall mean the average of the five amounts resulting from determining whichever of the following (i), (ii) or (iii) specified below in relation to shares of the class of which such treasury share is to be reissued shall be appropriate in respect of each of the five business days immediately preceding the day on which the treasury share is re-issued, as determined from information published by the relevant authority in relation to dealings on Euronext Growth Oslo, or its equivalent, reporting the business done in each of those five business days:

of the equivalent information published by the relevant authority in relation to dealings on Euronext Growth Oslo, or its equivalent.

Notes

• 1. Section 383 of the Companies Act 2014 provides for the automatic re-appointment of the auditor of an Irish company at a company's annual general meeting unless the auditor has given notice in writing of his unwillingness to be re-appointed or a resolution has been passed at that meeting appointing someone else or providing expressly that the incumbent auditor shall not be re-appointed. The statutory auditor, Mazars, is willing to continue in office. However, the Directors believe that it is important that shareholders are provided with an opportunity to have a say on the continuation in office of the statutory auditor and have included Resolution 2, which is an advisory non-binding resolution, for this purpose.
• 1. The Directors have no present intention of exercising the authority that will be granted by Resolution 4 however it will provide flexibility in the evaluation of alternative uses of capital and the Directors will only use the authority if they consider it to be in the best interests of the Company and its shareholders generally. The Company has made no decision as to whether any shares purchased under this authority will be cancelled or held in treasury.

VOTING / PROXY VOTING INSTRUCTIONS

Entitlement to Attend and Vote

• 3. The Company, pursuant to Section 1087G of the Companies Act 2014, specifies that only those shareholders registered in the register of members of the Company as at the close of business on 19 September 2022 (or in the case of an adjournment as at the close of business on the day that falls four days before the time of the adjourned meeting) shall be entitled to attend and vote at the Meeting in respect of the number of shares registered in their names at the time. Changes to entries in the register after that time will be disregarded in determining the right of any person to attend and/or vote at the Meeting.
• 1. If you hold ordinary shares in certificated (i.e. paper) form, you have several ways to exercise your right to vote:
  2. (a) by attending the Meeting in person; or
  3. (b) by appointing (either electronically or by returning a completed Proxy Form) the Chairperson of the Meeting (the "Chairperson") or another person as a proxy to vote on your behalf.
• 1. All resolutions at the Meeting will be put to a poll.

1. In the case of joint holders, the vote of the senior who tenders a vote, whether in person or by proxy, will be accepted to the exclusion of the votes of the other joint holder(s) and, for this purpose, seniority will be determined by the order in which the names stand in the register of members in respect of the share.

Appointment of Proxy

• 1. A shareholder (a registered member of the Company) who is entitled to attend and vote at the Meeting is entitled to appoint one or more proxies to attend, speak and vote on his behalf. A proxy need not be a shareholder of the Company. Appointment of a proxy will not preclude a shareholder from attending and voting at the Meeting should the shareholder subsequently wish to do so. You may appoint more than one proxy to attend, speak, ask questions relating to items on the agenda and vote at the Meeting in respect of separate share(s) held by you. Should you wish to appoint more than one proxy, please read carefully the explanatory notes accompanying the Proxy Form.

• 1. Euroclear Bank will, wherever practical, aim to have a voting instruction deadline of one hour prior to the Company's proxy appointment deadline (being 48 hours before the time appointed for the Meeting or any adjournment of the Meeting).
