EXPLANATORY NOTES TO THE AGENDA

2. Extension of the period for drawing up the Dutch statutory annual accounts and board report for the financial year ended December 31, 2023 (voting item)

It is proposed to extend the period for drawing up and making available for inspection at the Company's offices the Dutch statutory annual accounts and board report for the financial year ended December 31, 2023 by a maximum period of five months, as referred to in Section 2:101 of the Dutch Civil Code, in view of special circumstances.

The reason for the requested extension is that the Company is unable to file its annual accounts and board report for the year ended December 31, 2023 within the prescribed filing date without unreasonable effort or expense. The Company is still in the process of compiling certain required information to complete the filing. As a result, the Company requires additional time to prepare and review its consolidated financial statements and other related disclosures.

After finalizing the annual accounts and board report for the financial year 2023, the Management Board will convene an extraordinary general meeting of shareholders of the Company for the adoption of the Dutch statutory annual accounts and the discussion of the Dutch statutory board report for the financial year ended December 31, 2023.

3. Instruction to Ernst & Young Accountants LLP as the external auditor of the Company for the financial year ending December 31, 2024 (voting item)

It is proposed to instruct Ernst & Young Accountants LLP as the external independent Dutch auditor for the audit of the Company's annual accounts for the financial year ending December 31, 2024. If instructed, Ernst & Young Accountants LLP shall perform the statutory Dutch audit activities for the Company in relation to the Company's Dutch statutory annual accounts, board report and, to the extent required, sustainability reporting.

4. Discussion of the Company's dividend and reservation policy (discussion item)

The Company has never paid or declared any cash dividends on its shares, and the Company does not anticipate paying any cash dividends on its shares in the foreseeable future. The Company intends to retain available funds and future earnings to fund the development and expansion of its business. Under Dutch law, the Company may only pay dividends to the extent its shareholders' equity (eigen vermogen) exceeds the sum of the Company's paid-up and called-up share capital plus the reserves required to be maintained by Dutch law or by the Company's articles of association (if any). Subject to such restrictions, any future determination to pay dividends will be at the discretion of the Management Board and the Company's supervisory board (the "Supervisory Board") and will depend upon a number of factors, including the Company's results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law and other factors the Management Board and the Supervisory Board deem relevant. If and when the Company does intend to distribute a dividend, such dividend may be distributed in the form of cash only or shares only, through a combination of the foregoing (cash and shares) or through a choice dividend (cash or shares), in each case subject to applicable law.

5. Compensation of the Supervisory Board (voting item)

At the recommendation of the Company's compensation committee (the "Compensation Committee"), the Supervisory Board proposes the following changes to the compensation packages of the Supervisory Board members as of the financial year 2023 and onwards:

Cash component:

a. There will be no cash component that is part of the compensation packages of the Supervisory Board members;

b. in deviation of a. above, for the financial year 2023, Mary Sheahan will be granted a one-time cash bonus of EUR 25,000 (gross).

Equity component under the Company's long-term incentive plan:

a. Each member of the Supervisory Board shall annually receive an award of options ("Options") and restricted stock units ("RSUs") for ordinary shares in the Company's capital ("Shares") (such Options and RSUs collectively, the "LTIs") with a value of EUR 160,000 multiplied by the LTI Factor (as defined below);

b. the chairperson of the Supervisory Board shall annually receive additional LTIs with a value of EUR 120,000 multiplied by the LTI Factor (as defined below);

c. the vice-chairperson of the Supervisory Board shall annually receive additional LTIs with a value of EUR 80,000 multiplied by the LTI Factor (as defined below);

d. the chairperson of the Company's audit committee shall annually receive additional LTIs with a value of EUR 80,000 multiplied by the LTI Factor (as defined below);

e. the chairperson of the Compensation Committee shall annually receive additional LTIs with a value of EUR 16,000 multiplied by the LTI Factor (as defined below);

f. the LTIs shall be granted retrospectively for the preceding financial year following the audit of the Company's annual accounts over such financial year;

g. each LTI shall consist of:

i. RSUs for 75% of the value of the LTI; and

ii. Options for 25% of the value of the LTI;

h. for the purpose of calculating the value of the LTIs:

i. the assumed value of an Option shall be 66.67% of the End of Year VWAP (as defined below);

ii. the assumed value of an RSU shall be 100% of the End of Year VWAP (as defined below); and

iii. the "End of Year VWAP" shall be the volume-weighted average stock price of the Shares on the principal stock exchange where they have been admitted for trading calculated over a 60-trading day period preceding December 31 of the financial year preceding the relevant Grant Date;

i. the "LTI Factor" for the LTIs shall be calculated as follows:

i. the LTI Factor shall be 100% if the End of Year VWAP for the financial year preceding the relevant Grant Date (the "Reference FY") exceeds the End of Year VWAP for the financial year preceding the Reference FY by at least 25%;

ii. the LTI Factor shall be 75% if the End of Year VWAP for the Reference FY exceeds the End of Year VWAP for the financial year preceding the Reference FY by at least 15% but less than 25%; and

iii. the LTI Factor shall be 50% if the End of Year VWAP for the Reference FY exceeds the End of Year VWAP for the financial year preceding the Reference FY by less than 15%;

j. the LTIs shall:

i. vest in four equal instalments on each relevant anniversary of the Grant Date:

ii. vest in full upon the occurrence of a Change of Control, provided the holder of the LTIs is an Eligible Participant on the date of such Change of Control;

iii. expire on the ten-year anniversary of the applicable Grant Date;

iv. not be subject to any performance criteria (without prejudice to the applicable LTI Factor);

v. have no exercise price (as regards the RSUs comprised in the LTIs) and shall have FMV (as defined in the Company's long-term incentive plan) as exercise price (as regards the Options comprised in the LTIs); and

vi. be settled in Shares.

k. if a Supervisory Board member would serve as such and/or in any of the additional capacities described above for part, but not all, of a financial year, the entitlement to the LTIs shall be adjusted and, if already made, shall promptly be forfeited by such Supervisory Board member on a pro rata tempore basis; and

l. if a Supervisory Board member was in office during all or part of a financial year but would cease to be a Supervisory Board member before the LTIs are granted for such financial year, such former Supervisory Board member shall retain his or her entitlement to such LTIs subject to the terms set forth above.

Each of Mr. Hubert Birner, Mr. Guido Prehn and Mr. Eric Souêtre has waived the equity component of his compensation as described above, for the duration of his term as a member of the Supervisory Board.

6. Extension of authorization for the Management Board to issue shares and grant rights to subscribe for shares (voting item)

The Management Board has been authorized, for a period of five years following the 2023 annual general meeting of shareholders held on June 30, 2023 (the "2023 AGM"), to resolve to issue ordinary shares and/or grant rights to subscribe for ordinary shares, in each case up to the Company's authorized share capital included in its articles of association from time to time. It is proposed that this authorization be extended to expire five years following the date of this AGM. If the resolution proposed under this agenda item 6 is passed, the proposed authorization shall replace the currently existing authorization.

It is proposed that this authorization be extended to expire five years following the date of this AGM. If the resolution proposed under this agenda item 7 is passed, the proposed authorization shall replace the currently existing authorization.

8. Extension of authorization for the Management Board to acquire shares and depository receipts for shares in the Company's capital (voting item)

It is proposed that this authorization be renewed for a period of, and effectively extended until, 18 months following the date of the AGM for up to 20% of the Company's issued share capital (determined as at the close of business on the date of the AGM). If the resolution proposed under this agenda item 8 is passed, the proposed authorization shall replace the currently existing authorization.
