Protective Foundation [Abstract]
Protective foundation	17.Protective foundation According to the articles of association of the Company, up to 169,300,000 ordinary shares and up to 169,300,000 preferred shares with a nominal value of €0.12 per share are authorized to be issued. All shares are registered shares. No share certificates shall be issued. In order to deter acquisition bids, the Company’s general meeting of shareholders approved the right of an independent foundation under Dutch law, or protective foundation, to exercise a call option pursuant to the call option agreement, upon which preferred shares will be issued by the Company to the protective foundation of up to 100% of the Company’s issued capital held by others than the protective foundation, minus one share. The protective foundation is expected to enter into a finance arrangement with a bank or, subject to applicable restrictions under Dutch law, the protective foundation may request the Company to provide, or cause the Company’s subsidiaries to provide, sufficient funding to the protective foundation to enable it to satisfy its payment obligation under the call option agreement. These preferred shares will have both a liquidation and dividend preference over the Company’s ordinary shares and will accrue cash dividends at a pre-determined rate. The protective foundation would be expected to require the Company to cancel its preferred shares once the perceived threat to the Company and its stakeholders has been removed or sufficiently mitigated or neutralized. The Company believes that the call option does not represent a significant fair value based on a level 3 valuation since the preferred shares are restricted in use and can be cancelled by the Company. During the three months ended June 30, 2025, the Company expensed €15 thousand (2024: €12 thousand) of ongoing costs to reimburse expenses incurred by the protective foundation. During the six months ended June 30, 2025, the Company expensed €30 thousand (2024: €25 thousand) of ongoing costs to reimburse expenses incurred by the protective foundation.
