EXPLANATORY NOTES TO THE AGENDA

2. Distribution from the Company's distributable reserves (voting item)

On September 15, 2023, the Company announced distributing a one-time extraordinary dividend later this year, subject to shareholder approval. For that purpose, the Company's management board (the "Management Board"), with the approval of the Company's supervisory board (the "Supervisory Board"), has resolved to make a total distribution of EUR 184,380,959 (being a distribution of approximately EUR 0.53 per share in the capital of the Company) (the "Distribution").

The Distribution consists of two components: (i) an interim distribution from the Company's profits realized during the current financial year in the total amount of EUR 16,487,070 (the "Interim Profits Distribution") and (ii) a distribution from the Company's distributable reserves in the amount of EUR 167,893,889 (the "Distributable Reserves Distribution").

In accordance with Dutch law and the Company's articles of association, the Management Board, with the approval of the Supervisory Board, may resolve to make the Interim Profits Distribution without the approval of the Company's general meeting. However, in accordance with the Company's articles of association, the Management Board, with the approval of the Supervisory Board, does require a resolution of the Company's general meeting to make the Distributable Reserves Distribution. Therefore, this voting item only relates to the Distributable Reserves Distribution. If this voting item passes, the total Distribution will be made as described below. If this voting item does not pass, the Company will still make the Interim Profits Distribution.

The Company has determined that the shareholders of the Company (or, as applicable, eligible usufructuaries and pledgees) on November 3, 2023 shall be the parties entitled to the Distribution. Further, the Management Board, with the approval of the Supervisory Board, has determined that the Distribution shall be paid in euro on November 6, 2023 (the "Distribution Payment Date"), such that the ex-dividend date is November 2, 2023.
