Oncimmune Holdings plc

("Oncimmune" or the "Company")

Retail Offer

The Board of Oncimmune Holdings plc (the "Company") is pleased to announce a retail offer via BookBuild (the "Retail Offer") of new ordinary shares ("Ordinary Shares") of £0.01 each in the capital of the Company (the "Retail Offer Shares") at an issue price of 15 pence per New Ordinary Share (as defined below) (the "Issue Price").

In addition to the Retail Offer, the Company announced earlier today that it is also conducting a placing and proposed subscription of new Ordinary Shares (the "Placing Shares" and "Subscription Shares" respectively and together with the Retail Offer Shares, the "New Ordinary Shares") at the Issue Price (the "Placing" and "Subscription" together with the Retail Offer, the "Issue"). A separate announcement has been made regarding the Placing and Subscription and their terms. For the avoidance of doubt, the Retail Offer is not part of the Placing or Subscription and completion of the Placing and/or the Subscription is not conditional on the completion of the Retail Offer.

The Issue Price represents a premium of approximately 8 per cent to the closing share price of 13.9p per existing Ordinary Share on 17 October 2024, being the last business day prior to the announcement of the Issue.

The Retail Offer is conditional on the New Ordinary Shares to be issued pursuant to the Retail Offer being admitted to trading on the AIM market operated by the London Stock Exchange ("Admission"). Admission of the New Ordinary Shares pursuant to the Retail Offer is expected to take place at 8.00 a.m. on 11 November 2024. Completion of the Retail Offer is conditional, inter alia, upon the completion of the Placing and Subscription and the passing of certain resolutions by the Company's shareholders at a General Meeting to be held at 11.00 a.m. on 8 November 2024.

The net proceeds from the Issue provides additional working capital to support commercial traction.

Expected Timetable in relation to the Retail Offer

Any changes to the expected timetable set out above will be notified by the Company through a Regulatory Information Service. References to times are to London times unless otherwise stated.

Dealing Codes

Retail Offer

The Company values its retail shareholder base, which has supported the Company alongside institutional investors. Given the support of retail shareholders, the Company believes that it is appropriate to provide its retail shareholders in the United Kingdom the opportunity to participate in the Retail Offer. The Company is therefore making the Retail Offer available in the United Kingdom through the financial intermediaries which will be listed, subject to certain access restrictions, on the following website: https://www.bookbuild.live/deals/D10VP7/authorised-intermediaries

Cavendish Capital Markets Limited will be acting as retail offer coordinator in relation to this Retail Offer (the "Retail Offer Coordinator").

Existing retail shareholders can contact their broker or wealth manager ("Intermediary") to participate in the Retail Offer. In order to participate in the Retail Offer, each intermediary must be on-boarded onto the BookBuild platform and agree to the final terms and the retail offer terms and conditions which regulate, inter alia, the conduct of the Retail Offer on market standard terms and provide for the payment of commission to any intermediary that elects to receive a commission and/or fee (to the extent permitted by the FCA Handbook Rules) from the Retail Offer Coordinator (on behalf of the Company).

Any expenses incurred by any intermediary are for its own account. Investors should confirm separately with any intermediary whether there are any commissions, fees or expenses that will be applied by such intermediary in connection with any application made through that intermediary pursuant to the Retail Offer.

The Retail Offer will be open to eligible investors in the United Kingdom following release of this announcement. The Retail Offer is expected to close at 4:35pm on 31 October 2024 . Investors should note that financial intermediaries may have earlier closing times. The Retail Offer may close early if it is oversubscribed.

If any intermediary has any questions about how to participate in the Retail Offer on behalf of existing retail shareholders, please contact BookBuild at email: support@bookbuild.live.

The Retail Offer the subject of this announcement is and will, at all times, only be made to, directed at and may only be acted upon by those persons who are, shareholders in the Company. To be eligible to participate in the Retail Offer, applicants must meet the following criteria before they can submit an order for Retail Offer Shares¹: (i) be a customer of one of the participating intermediaries listed on the above website; (ii) be resident in the United Kingdom and (iii) be a shareholder in the Company (which may include individuals aged 18 years or over, companies and other bodies corporate, partnerships, trusts, associations and other unincorporated organisations and includes persons who hold their shares in the Company directly or indirectly through a participating intermediary). For the avoidance of doubt, persons who only hold CFDs, Spreadbets and/or similar derivative instruments in relation to shares in the Company are not eligible to participate in the Retail Offer.

The Company reserves the right to scale back any order at its discretion. The Company reserves the right to reject any application for subscription under the Retail Offer without giving any reason for such rejection.

It is vital to note that once an application for Retail Offer Shares has been made and accepted via an intermediary, it cannot be withdrawn.

The New Ordinary Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with existing Ordinary Shares including the right to receive all dividends and other distributions declared, made or paid after their date of issue.

The Retail Offer is an offer to subscribe for transferable securities, the terms of which ensure that the Company is exempt from the requirement to issue a prospectus under Regulation (EU) 2017/1129 as it forms part of UK law by virtue of the European Union (Withdrawal) Act 2018. It is a term of the Retail Offer that the aggregate total consideration payable for the Retail Offer Shares will not exceed £300,000³ (or the equivalent in Euros). The exemption from the requirement to publish a prospectus, set out in section 86(1)(e) of the Financial Services and Markets Act 2000 (as amended), will apply to the Retail Offer.

The Retail Offer is not being made into any jurisdiction other than the United Kingdom or to US Persons (as defined in Regulation S of the US Securities Act 1933, as amended).

No offering document, prospectus or admission document has been or will be prepared or submitted to be approved by the Financial Conduct Authority (or any other authority) in relation to the Retail Offer, and investors' commitments will be made solely on the basis of the information contained in this announcement and information that has been published by or on behalf of the Company prior to the date of this announcement by notification to a Regulatory Information Service in accordance with the Financial Conduct Authority's Disclosure Guidance and Transparency Rules and the Market Abuse Regulation (EU Regulation No. 596/2014) ("MAR") as it forms part of United Kingdom law by virtue of the European Union (Withdrawal) Act 2018 (as amended).

There is a minimum subscription of £100.00 per investor under the terms of the Retail Offer which is open to investors in the United Kingdom subscribing via the intermediaries which will be listed, subject to certain access restrictions, on the following website: https://www.bookbuild.live/deals/D10VP7/authorised-intermediaries

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK MiFIR Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK MiFIR Product Governance Requirements) may otherwise have with respect thereto, the Retail Offer Shares have been subject to a product approval process, which has determined that the Retail Offer Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in paragraphs 3.5 and 3.6 of COBS; and (ii) eligible for distribution through all permitted distribution channels (the "Target Market Assessment").

The Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Retail Offer.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A respectively of COBS; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Retail Offer Shares.

For the avoidance of doubt, the EU Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase or take any other action whatsoever with respect to the Retail Offer Shares.
