Scancell Holdings plc

("Scancell" or the "Company")

Oversubscribed Placing upsized to £10.3 million with significant participation from both existing and new healthcare specialist investors

Scancell Holdings plc (AIM: SCLP), the developer of novel immunotherapies for the treatment of cancer, is pleased to announce, conditional on Admission, completion of a significantly oversubscribed placing and subscription as announced by the Company yesterday on 4 December 2024 (the "Launch Announcement").

A total of 97,467,141 Placing Shares have been placed by Panmure Liberum Limited ("Panmure Liberum") and WG Partners LLP ("WG Partners") at the Issue Price of 10.5 pence per Ordinary Share. Concurrently with the Placing, a Director of the Company has conditionally subscribed for 190,476 Subscription Shares pursuant to the Subscription at the Issue Price.

Together, the Placing Shares and the Subscription Shares in aggregate comprise 97,657,617 new Ordinary Shares, raising total gross proceeds of approximately £10.3 million. The Placing Shares and the Subscription Shares together represent approximately 10.5 per cent. of the Existing Ordinary Shares.

RETAIL OFFER

As announced yesterday, the Company also launched the Retail Offer through the Winterflood Retail Access Platform to raise up to approximately a further £1 million of gross proceeds (the "Retail Offer" and together with the Placing and Subscription, the "Capital Raise"). The Retail Offer is expected to close at 9.00 a.m. on 9 December 2024, or such later time and date as the Company, Panmure Liberum and Winterflood may agree, the results of which are expected to be announced on or around 9 December 2024.

Phil L'Huillier, Chief Executive Officer, commented: "We are pleased to have secured this additional funding, which will allow us to further progress our lead cancer vaccine, SCIB1, and the next generation iSCIB1+, whilst also extending our cash runway to H2 2026. The data generated to date from the SCOPE study, showing progression free survival of 80% with a 20% complete response rate, is very promising and gives us continued confidence in the potential of SCIB1 as a treatment for advanced melanoma. Our focus continues to be on its continued clinical development, and we are actively working on preparations for the next stage of development. I would like to thank our investors, new and existing, for their support, and we look forward to providing further updates on our pipeline in due course."

Related Party Transactions

Redmile Group, LLC ("Redmile") and Vulpes Investment Management ("Vulpes"), existing shareholders of the Company, have agreed to conditionally subscribe for 28,571,428 and 10,476,190 Placing Shares respectively, at the Issue Price, both of whom are considered to be related parties of the Company in accordance with Rule 13 of the AIM Rules for Companies by virtue of their status as substantial shareholders of the Company.

Additionally, Sath Nirmalananthan, a Director and the Chief Financial Officer of the Company, who is deemed to be a related party pursuant to Rule 13 of the AIM Rules for Companies, has conditionally subscribed for 190,476 Ordinary Shares at the Issue Price as part of the Subscription (together, the "Related Party Transactions"):

* These numbers and percentages are calculated assuming that the Placing and the Subscription complete and the 9,523,809 Retail Offer Shares are issued under the Retail Offer and that none of the outstanding share options are exercised or Convertible Loan Notes are converted.

** excluding any potential conversion of the Convertible Loan Notes

Dr Jean-Michel Cosséry, Dr Phil L'Huillier, Professor Lindy Durrant, Susan Clement Davies and Dr Ursula Ney, being the Directors independent of the Related Party Transactions, having consulted with the Company's nominated adviser, Panmure Liberum, consider that the terms of the Related Party Transactions are fair and reasonable insofar as Shareholders are concerned.

Admission

An application has been made to London Stock Exchange plc for the Placing Shares and the Subscription Shares to be admitted to trading on AIM. It is expected that Admission and settlement of the Placing Shares, the Subscription Shares and such number of Retail Offer Shares as are subscribed for pursuant to the Retail Offer, will become effective and dealings in the Placing Shares and the Subscription Shares will commence at 8.00 a.m. on or around 10 December 2024. The Placing and the Subscription are conditional upon, among other things, Admission becoming effective.

The Placing Shares, the Subscription Shares and the Retail Offer Shares, when issued, will be credited as fully paid and will rank pari passu in all respects with the Company's then existing Ordinary Shares, including the right to receive all dividends and other distributions declared, made or paid on or in respect of such shares after the date of issue.

Panmure Liberum is acting as Joint Bookrunner, Joint Broker and Nominated Adviser in relation to the Placing and WG Partners is acting as Joint Bookrunner and Joint Broker in relation to the Placing.

Capitalised terms used in this announcement have the meaning as defined in the Launch Announcement unless otherwise stated.

For the purposes of UK MAR, the person responsible for arranging for the release of this announcement on behalf of the Company is Sath Nirmalananthan, Chief Financial Officer.

Notes for Editors

About Scancell

Scancell is a clinical stage immunotherapy company that is leveraging its proprietary research, built up over many years of studying the human adaptive immune system, to generate novel medicines to treat significant unmet needs in cancer.

The Company is building a pipeline of innovative products by utilising its four technology platforms: Moditope® and ImmunoBody® for vaccines and GlyMab® and AvidiMab® for antibodies. Adaptive immune responses include antibodies and T cells (CD4 and CD8), both of which can recognise damaged or infected cells. In order to destroy such cancerous or infected cells, Scancell uses either vaccines to induce immune responses or monoclonal antibodies (mAbs) to redirect immune cells or drugs.

The Company's approaches are that vaccines (ImmunoBody® and Moditope®) use unique receptors to target antigens to activated antigen presenting cells whereas its mAb portfolio targets glycans or sugars that are added onto proteins and / or lipids (GlyMab®) or enhances the potency of antibodies and their ability to directly kill tumour cells (AvidiMab®).

The Company's lead assets are the cancer vaccines, SCIB1 and the next generation iSCIB1+, which is being evaluated in a Phase 2 SCOPE trial for the treatment of advanced melanoma.

UK Product Governance Requirements

Solely for the purposes of the product governance requirements contained within the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Rules"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Rules) may otherwise have with respect thereto, the New Ordinary Shares have been subject to a product approval process, which has determined that such New Ordinary Shares are: (a) 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 Chapter 3 of the FCA Handbook Conduct of Business Sourcebook ("COBS"); and (b) eligible for distribution through all permitted distribution channels (the "UK target market assessment"). Notwithstanding the UK target market assessment, distributors should note that: the price of the New Ordinary Shares may decline and investors could lose all or part of their investment; the New Ordinary Shares offer no guaranteed income and no capital protection; and an investment in the New Ordinary Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The UK target market assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the UK target market assessment, the Joint Bookrunners will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the UK target market assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of COBS 9A and COBS 10A, respectively; 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 New Ordinary Shares. Each distributor is responsible for undertaking its own UK target market assessment in respect of the New Ordinary Shares and determining appropriate distribution channels.
