Recent legislative changes to the Corporations Act mean there are new options available to Allkem Limited (ACN 112 589 910) (Allkem) shareholders as to how you receive communications from Allkem.

Allkem will no longer be sending physical meeting documents unless you request a copy to be posted.

Allkem encourages all shareholders to provide an email address so we can communicate with you electronically when shareholder notices become available online, for items such as meeting documents and annual reports.

Shareholders can still elect to receive some or all of their communications in physical or electronic form, or elect not to receive certain documents such as annual reports. To review your communications preferences, or sign up to receive your shareholder communications via email, please update your details at: www.computershare.com.au/easyupdate/AKE.

If you are a shareholder and would like a physical copy of a communication, need further information about the options available to you or have questions about your holding, please either visit: www.investorcentre.com/contact or Contact Allkem’s Share Registry:
