("Aptamer Group", "APTA" or the "Company")

Supplementary Conditional Placing for £60,000

Aptamer Group (AIM:APTA), the developer of novel Optimer® binders to enable innovation in the life sciences industry, announces that, in addition to the Placing and Subscription announced on 24 July 2024 (the "Fundraising"), it has agreed to issue a further 30,000,000 New Ordinary Shares ("Supplementary Placing Shares") at the same issue price of 0.2p per share, raising £60,000 (before expenses), which will be for working capital purposes.

This additional sum has arisen due to a reconciliation error by the Company's broker, Turner Pope Investments (TPI) Ltd ("Turner Pope"), relating to client orders received in the Fundraising. Turner Pope noticed this matter yesterday and informed the Company and the Board has agreed to issue the Supplementary Placing Shares.

Notwithstanding the circumstances under which the proposed issue of the Supplementary Placing Shares has arisen, they will not form part of the Fundraising and will be issued as a separate tranche. Both the conditional element of the Fundraising and the Supplementary Placing Shares are subject to shareholder approval of the resolutions at the Company's General Meeting, which is scheduled for 13 August 2024.

Subject to the passing of the resolutions at the General Meeting, admission of the Supplementary Placing Shares is expected to become effective and dealings are expected to commence at 8.00 a.m. on 14 August 2024 ("Admission").

Total Voting Rights

Immediately following Admission the Company will have 1,920,343,673 ordinary shares of £0.001 each in issue.

The Company does not hold any shares in treasury and all of the Ordinary Shares have equal voting rights. Therefore, the figures above represent the total voting rights in the Company and may be used by shareholders as the denominator for the calculations by which they can determine if they are required to notify their interest in, or a change to their interest in the Company under the Rules.
