PrimaryBid Offer

Oxford (AIM: OBD), a biotechnology company developing precision medicine tests based on the EpiSwitch® 3D genomics platform is pleased to announce, a conditional offer for subscription of new ordinary shares of 1 pence each in the capital of the Company ("Ordinary Shares") via PrimaryBid (the "PrimaryBid Offer") at an issue price of 9 pence per new Ordinary Share (the "Issue Price"), being a discount of approximately 21 per cent to the closing price of the Company's existing Ordinary Shares on 12 March 2024. The Company is also conducting a placing of new Ordinary Shares at the Issue Price by way of an accelerated bookbuilding process (the "Placing") as announced earlier today. The Company is further conducting direct subscriptions for new Ordinary Shares at the Issue Price (the "Subscriptions", together with the PrimaryBid Offer and the Placing, the "Fundraising").

The PrimaryBid Offer is conditional on the approval by the shareholders of the Company at a General Meeting to be held on 3 April 2024 at the Company's registered offices. The PrimaryBid Offer is further conditional on the new Ordinary Shares to be issued pursuant to the Fundraising being admitted to trading on AIM ("Admission"). Admission is expected to take place at 8.00 a.m. on 8 April 2024. The PrimaryBid Offer will not be completed without the Placing also being completed.

The Company will use the funds raised for working capital to support its ongoing commercial development including:

? investment in marketing, business development and sales & market access activity to continue to grow orders and adoption of the Company's two on-market laboratory developed tests, EpiSwitch PSE and EpiSwitch CiRT;

? operation of the Company's clinical, research and reference laboratory facilities worldwide; and

? pursuit of partnering / out-licensing opportunities for its two readily deployable pipeline assets, EpiSwitch NST and EpiSwitch SCB.

Reason for the PrimaryBid Offer

While the Placing has been structured as a non-pre-emptive offer so as to minimise cost and time to completion, the Company values its retail investor base and is therefore pleased to provide retail investors with the opportunity to participate in the PrimaryBid Offer.

Existing shareholders and new investors can access the PrimaryBid Offer through PrimaryBid's website and on PrimaryBid's app. The PrimaryBid app is available on the UK Apple App Store and Google Play Store.

Investors can also participate through PrimaryBid's extensive partner network of investment platforms, retail brokers and wealth managers, subject to such partners' participation. Participating partners include:

· AJ Bell;

· Hargreaves Lansdown; and

· interactive investor.

Applications for new Ordinary Shares through participating partners can be made from tax efficient savings vehicles such as ISAs or SIPPs, as well as GIAs. Some partners may only accept applications from existing shareholders.

After consideration of the various options available to it, the Company believes that the separate PrimaryBid Offer is in the best interests of shareholders, as well as wider stakeholders in the Company.

The PrimaryBid Offer will open to investors resident and physically located in the United Kingdom following the release of this Announcement. The PrimaryBid Offer is expected to close at 8:30 p.m. on 13 March 2024 and may close early if it is oversubscribed.

There is a minimum subscription amount of £250 per investor in the PrimaryBid Offer.

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

Investors who apply for new Ordinary Shares through PrimaryBid's website or PrimaryBid's app will not be charged any fee or commission by PrimaryBid. It is vital to note that once an application for new Ordinary Shares has been made and accepted via PrimaryBid, that application cannot be withdrawn.

Investors wishing to apply for new Ordinary Shares through their investment platform, retail broker or wealth manager using their ISA, SIPP or GIA should contact them for details of their terms and conditions, process and any relevant fees or charges.

The new Ordinary Shares to be issued pursuant to the PrimaryBid Offer will be issued free of all liens, charges and encumbrances and will, when issued and fully paid, rank pari passu in all respects with the new Ordinary Shares to be issued pursuant to the Placing and the Company's existing Ordinary Shares.
