Quantum Base Holdings plc

("Quantum Base" or the "Company")

First Day of Dealings on AIM and Completion of Fundraising

Quantum Base (AIM: QUBE), the quantum science company focused on creating a new global standard in authentication, is pleased to announce that the admission of its ordinary shares of 0.1 pence each ("Ordinary Shares") to trading on the AIM Market ("AIM"), a market operated by the London Stock Exchange, will take place today ("Admission").

Admission follows the successful completion of a fundraising of £4.8 million (before expenses) through a placing of new Ordinary Shares with certain institutional and other investors (the "Placing"), and a significantly oversubscribed retail offer of new ordinary shares in the capital of the Company via RetailBook Limited (the "RetailBook Offer" and, together with the Placing, the "Fundraising"), at an issue price of 23.1 pence per new Ordinary Share (the "Issue Price").

Dealings in the Ordinary Shares will commence at 8:00 a.m. today under the TIDM "QUBE" and ISIN code GB00BTXYPJ53.

Quantum Base Highlights

·    A New Global Standard: Quantum Base is focused on creating a new global standard in authentication through its patented Q-ID solution; a near unbreakable and non-replicable authenticity tags that can be applied to a vast array of products, significantly mitigating counterfeiting.

·    Secure Technology: The technology underpinning Q-ID harnesses the randomness that is inherent at a nanometre length scale. The sheer volume and variation of the interactions between molecules that occur at nanoscale means that there is virtually an infinite number of combinations that can be created. The Q-ID is practically impossible to replicate using even the most advanced available technology.

·    Vast Applicable Market and Versatile Product: Counterfeiting is estimated to cost businesses and tax authorities at least $2.8 trillion in lost revenue per year. Q-IDs can be applied to almost any print line and in certain cases can be entirely non-intrusive to a product's existing design, meaning that they can be utilised in a vast number of end markets.

·    Ease and Speed of Integration: The authentication process to identify printed tags is undertaken using existing and unmodified smartphone technology coupled with the Quantum Base software. This process does not require a change of existing consumer behaviour, or any further hardware or infrastructure.

·    Proven and Protected Technology: The Q-ID technology and its application processes have undergone rigorous adversarial and competitive testing from existing partners and potential clients. Additionally, the science has undergone peer review, with publication in leading open-access science journals, and the intellectual property surrounding Q-IDs is protected by a broad patent portfolio.

·    Framework Agreements with Security Printers: In its first stage of commercialisation, the Company has signed two framework agreements with leading security printers, with an initial focus on tax stamps. The Directors believe that the tax stamp industry represents a strong first application for Q-IDs as they are produced globally in vast quantities and the Q-ID stamp can be readily applied to existing print runs. The Company intends to access further customers using channel partnerships across a wide range of verticals.

Fundraising Highlights

·    Successful fundraising through the issuance of an aggregate of 20,832,016 new Ordinary Shares ("Fundraising Shares"), raising gross proceeds of approximately £4.8 million for the Company, at the Issue Price.

·    At the Issue Price, the Company will have a market capitalisation on Admission of approximately £14.8 million.

·    The Board intends to use the net proceeds of the fundraise to fund its commercial development and sales initiatives in the main following areas:

o  Commercial hires

o  Product development - tax stamps

o  Product development - brand protection

o  Science and software hires

·    Strand Hanson Limited acted as Nominated and Financial Adviser to the Company in connection with Admission.

·    Cavendish Capital Markets Limited acted as broker in connection with the Placing and is acting as sole broker from Admission.

Tom Taylor, CEO of Quantum Base, commented:

"I am thrilled to commence trading on AIM today, marking a key step in our decade long journey from a Lancaster University spin-out to a British scientific success story. Floating on AIM gives us direct access to a large, sophisticated pool of investors, and provides further independence and credibility for our business.

"The success of the Fundraise is a strong endorsement of our mission to cement ourselves as the new global standard in authentication which, in the face of a growing counterfeiting problem, is more important than ever. The funds raised will enable us to further accelerate commercialisation and expand into new product lines.

"I would first like to thank the entire Quantum Base team for their positive engagement throughout this process, as well as our team of advisers for their continuous hard work. I would also like to thank our partners and our new investors for sharing our vision for the Company, and I look forward to you sharing in our success as we work to deliver value for all our stakeholders whilst establishing Quantum Base as the leading anti-counterfeit solution."
