Dear Shareholder
UNMARKETABLE PARCEL SALE FACILITY – DISPOSAL NOTICE
We are writing to advise you that Alterity Therapeutics Limited (ASX:ATH) (Company) has established an unmarketable parcel sale facility (Facility) for shareholders who hold less than $500 in value of fully paid ordinary shares in the Company (Shares) (Unmarketable Parcel) as at 7.00pm (AEST) on 9 March 2026 (Record Date).
The Company is providing this Facility to assist holders of Unmarketable Parcels who might otherwise find it difficult to sell their Shares without incurring brokerage or handling costs, due to the size of their holdings.
Holders of Unmarketable Parcels may opt out of the Facility as noted below.
Our registry records show that you held an Unmarketable Parcel of less than 62,500 Shares in the Company, based on the Company’s closing price (Sale Price) for Shares on the Record Date of $0.008.
In accordance with clause 2.7(a) of the Company’s constitution (Constitution), if you hold Shares in a CHESS Holding and they remain in a CHESS Holding after 7.00pm (AEST) on Friday, 24 April 2026 (Closing Date), the Company may, without further notice, remove those Shares from the CHESS Holding to an Issuer Sponsored Holding for the purposes of divestment in accordance with this notice.
The Company will pay all costs of the sale for holders of an Unmarketable Parcel who use this Facility, excluding tax consequences from the sale which remain the shareholder's responsibility. In accordance with clause 2.7(b) of the Constitution, the Company may sell Shares under the Facility on the terms and in the manner which the Company’s Directors consider appropriate. You will receive your pro rata share of the proceeds of the sale of all Shares sold under the Facility, without any deduction for brokerage or handing costs.
As the Company has determined that all payments to shareholders are to be made via direct credit to their nominated bank account, please ensure your account details are up to date with the Company’s share registry, Automic Pty Ltd (Automic). You can update your banking and personal details by logging in or registering via the Automic Investor Portal at: https://portal.automic.com.au/investor/home . If you require further assistance, please contact Automic on Australia: 1300 288 664 Overseas: +61 2 9698 5414.
What do you need to do if you wish to sell your Unmarketable Parcel?
In accordance with clause 2.7(a) of the Constitution, if you wish to sell your Unmarketable Parcel you do not need to take any action. Your Shares will be sold through the Facility after the Closing Date and the proceeds of the sale paid to you in accordance with the timetable below.

INFORMATION SHEET - UNMARKETABLE PARCEL SALE FACILITY
Why is the Company Implementing the Facility?
The Company welcomes the support of all shareholders, however, the administrative costs in producing and distributing shareholder communications and maintaining small holdings on the register through registry fees can be disproportionately high when compared with the dollar value of small holdings. Additionally, the Facility will assist holders with a small number of Shares who would find it difficult or expensive to dispose of those Shares through the normal means.
Does the Company have the authority to sell my Shares?
Under ASX Listing Rule 15.13 and clause 2.7 of the Constitution, the Company has the right to sell Unmarketable Parcels, unless shareholders give notice to the Company before the Closing Date that they wish to retain their Shares or acquire additional Shares such that their holding at the Closing Date comprises a marketable parcel.
What should I do if I wish to sell my Unmarketable Parcel of Shares?
If you wish to sell your Shares without incurring brokerage or handling costs, you can either:
| ● | complete the enclosed Share Sale Election Form, notifying the Company of your election to sell; or | |
| ● | alternatively, simply refrain from taking any action. |
By refraining from taking any action, you will be deemed to have irrevocably appointed the Company as your agent:
| ● | to sell all your Shares at a price to be determined by when and how the Shares are sold and without any cost being incurred by you; and | |
| ● | to deal with the proceeds of the sale as detailed in this Information Sheet. |
If you take no action, your Shares will be sold through the Facility after 24 April 2026 (Closing Date) and the proceeds (less costs) will be paid to you.
When will my Shares be sold under the Facility?
The sale of Shares under the Facility will occur as soon as practicable after the Closing Date.
Can I purchase more Shares, so my Shares will not be sold?
If you increase your holding so that the number of Shares held is equal to $500, the equivalent of 62,500 Shares (i.e., a Marketable Parcel) or more at the Closing Date, then the Company will not sell your Shares under the Facility.

What if I hold multiple Unmarketable Parcels?
If you hold multiple holdings that, in isolation, are deemed to be Unmarketable Parcels, but when aggregated would constitute a Marketable Parcel, you can contact Automic to have those holdings amalgamated into one holding so that this is reflected on the register before the Closing Date. If you do not do this, each of your holdings will be treated as Unmarketable Parcels.
When and how will I receive sale proceeds?
The proceeds from the sale of your Shares will be remitted to you as soon as practicable after the completion of the Facility. The expected payment date is as soon as practicable after 7 May 2026 and in any event within eight weeks of the Closing Date. The payment will be made into the bank account nominated by you to Automic.
If you do not have a bank account nominated with Automic at the time of the payment, the payment will be held by Automic until bank account details are nominated by you.
Important Notes
This Information Sheet and accompanying letter do not constitute advice, nor a recommendation to buy, sell or hold Shares in the Company, nor that the Facility is the best way to sell your Shares.
If you are in doubt about what to do, you should consult your legal, financial, taxation or other professional adviser.
The Company reserves the right to change any of the dates referred to in the accompanying letter, this Information Sheet or the Share Sale Election Form by written notice to ASX. The Company may, before a sale of Shares is completed under the Facility, suspend or terminate the Facility, either generally or in specific cases.
