INVESTOR INFORMATION

Communications Preferences Update

Recent legislative changes to the Corporations Act 2001 (Cth) effective 1 April 2022 mean there are new options available to you as a securityholder as to how you elect to receive your communications. Altium Limited will no longer send physical meeting documents to you unless you request a copy to be mailed to you.

We encourage you to provide an email address so that we can communicate with you electronically when shareholder notices become available online for items such as meeting documents, dividend statements and annual reports. You can make a standing election or an ad hoc request to receive, or not to receive, some or all of your securityholder communications in physical or electronic form.

To review or update your current communications preferences, please update your details via our Share Registry website at www.computershare.com/au. You will need your Security Reference Number (SRN) or Holder Identification Number (HIN) and your postcode to verify your identity.

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, visit www.computershare.com/au or contact the Registry:

How is the tax paid on my dividends?

All companies must deduct tax at the top marginal rate plus the Medicare levy from unfranked dividends and interest payable to investors who have not supplied their Tax File Number/Australian Business Number (TFN/ABN). Tax will not be deducted from the franked portion of dividends. Certain pensioners are exempt from supplying their TFN. If you are an eligible pensioner you should complete the TFN exemption section to claim exemption from quoting your TFN (refer to explanation section below).

Non-residents

If, for taxation purposes, you are a non-resident of Australia (or in certain cases a recently arrived resident), then your dividend/interest may be subject to special tax provisions which require tax to be withheld before payment of dividends/interest is made. If your postal address is outside Australia you will be treated as a non-resident.

Quotation Optional and Privacy Requirements

The quotation of your TFN/ABN is optional and you are not required to provide your TFN/ABN if you do not wish to do so. It should also be noted that the details provided with respect to your TFN will be treated confidentially in accordance with strict privacy guidelines. It is not an offence if you choose not to quote your TFN/ABN, but if you do not, tax may be taken out of your dividends/interest. If you quote your TFN/ABN, no tax will be taken out of dividends/interest paid on your investment. For more information about the use of TFN/ABN on your investment, please contact the Australian Tax Office.

For more information and TFN notification forms please go to the Computershare website at www-au.computershare.com

For lost cheques or other dividend enquiries you should contact Computershare Investor Services Pty Limited.

When accessing some information online or by phone you may be required to provide your Security Reference Number (SRN) or Holder Identification Number (HIN) as shown on your Issuer Sponsored/CHESS statements and other personal details such as your postcode.
