Notes

Allocation to a registration

This form can be taken into account only if it can be clearly allocated to a registration. If this form cannot be allocated because of a lack of or incorrect registration or because the information provided in this form is incomplete or illegible, voting rights by way of postal vote, by company-nominated proxies or by an authorized representative cannot be exercised on the basis of the instructions in this form. This form is not mandatory. You may also use another declaration in text form.

Information on this form

Please fill out this form legibly and in full. For the required information on the declaring person, please use the same information as stated on your registration confirmation, which is sent to you after proper registration.

Voting rights exercised by authorization/instructions to company-nominated proxies or postal vote

You also have the option to use the company's InvestorPortal at asm.lanxess.com to grant authorizations/instructions to company-nominated proxies or to exercise voting rights via postal vote. Please grant the authorization/instructions to the company-nominated proxies or cast your postal votes online via the InvestorPortal by the time stipulated by the chairman of the meeting in the course of the voting. Until such time, issued authorizations may be revoked or instructions or your postal vote changed on the Internet.

If you should use this form to issue an instruction to the proxy or cast a postal vote, please make an 'x' for all proposed resolutions. If authorized, the proxies only exercise the voting right according to instructions. Your instructions to proxies/your postal vote refer in each case to the resolutions proposed by the management published in the notice convening the Annual Stockholders' Meeting in the German Federal Gazette. Make an 'x' in the YES field to accept a resolution, in the NO field to reject it and in the ABST. field to abstain. If you do not insert any or unclear instructions, this will be deemed to be an instruction to abstain or an abstention, respectively.

If you do not wish to grant the authorization/instructions to the company-nominated proxies or cast postal votes online, the authorization/instructions or postal votes must be received at the following address no later than May 23, 2024, 24:00 hours (CEST):

LANXESS Aktiengesellschaft

c/o Computershare Operations Center 80249 München

E-Mail: [e-mail]

It is not possible for proxies to exercise other participation rights (such as asking questions, proposing motions, submitting declarations, or objecting to resolutions of the Annual Stockholders' Meeting). If you wish to exercise your stockholder rights beyond the scope described above, you must therefore exercise your rights yourself or authorize a third party.

Third-party authorization

Stockholders, once authorization is appropriately granted, can be represented in the exercise of their voting right and their other rights by an authorized representative - e.g. an intermediary, a voting rights advisor, a stockholders' association or other third party. Authorized representatives can exercise the voting right for Stockholders they represent only by way of postal vote or by granting (sub-)authorization to company-nominated proxies. Evidence of the appointment of an authorized representative may also be transmitted to the Company via the email address [e-mail]. You can also grant, amend or revoke authorization to third parties online via the InvestorPortal at asm.lanxess.com. For the authorized representative to participate electronically and exercise stockholder rights via the InvestorPortal, the authorizer must give the authorized representative the login details sent with the confirmation of registration. Please expressly inform your authorized representative accordingly.

If proxy is granted according to Section 135 AktG (proxy granted to intermediaries, voting rights advisors, stockholders' associations or professional agents), there is no text form requirement. However, the proxy statement must be verifiably recorded by the proxy. The proxy statement must furthermore be complete and may contain only statements related to exercising voting rights. In these cases, Stockholders are asked to check the form of proxy with the institutions or persons being authorized in due time.
