Dr. Roch Doliveux, Chair and Interim CEO, commented: "Accessing Homology’s unique AAV capabilities is a major advancement in Oxford Biomedica’s goal to become an innovative global viral vector leader that provides solutions to Cell and Gene Therapy (C&GT) Biotech and Biopharma companies for their process development and manufacturing needs across key viral vectors. Process Development/CMC being one of the most important critical success factors to ensure efficacy, safety and affordability of C&GT, Oxford Biomedica is in a strong position to enable our customers to bring their new medicines to many more patients and change their lives. We look forward to working with Homology’s impressive team and uniquely robust processes to achieve world-leadership as a provider of AAV solutions in addition to enhancing our leadership in lentiviral vectors. Having a US base brings us closer to customers, talent, innovation in academia and pools of capital all of which will allow growth and building a market leadership position."

Arthur Tzianabos, Ph.D., President and Chief Executive Officer of Homology, said: "We chose Oxford Biomedica for its leadership in viral-based manufacturing and prestigious global client base, and we believe that Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business will build upon the strengths of both companies. Our leadership in AAV process development and CMC, which resulted from establishing internal capabilities early on, has enabled us to advance three programmes from discovery into the clinic within five years. We believe the opportunity in Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business further leverages the value we created in this broad capability, including the demonstrated expertise of our team, to provide much-needed high-quality viral vector to other companies and, importantly, more patients around the world. . Additionally, the $130 million cash infusion, coupled with the reduction in operating expenses, significantly extends our runway and supports the continued advancement of our programs and genetic medicines platform. We believe our ownership stake in Oxford Biomedica Solutions, continued access to our AAV ‘plug and play’ manufacturing platform as a preferred customer, and our ability to benefit from any further manufacturing innovations, will be key value drivers for Homology."

Dr. Roch Doliveux commenting on John’s departure added: "I would like to express my sincere appreciation for John Dawson’s leadership and achievements as CEO. He and the world-class management team he has built have worked relentlessly in selecting the best AAV partner and creating this potentially transformative deal for the Group. This makes it easier to support John’s decision to step down at this time. I am delighted that he will remain a Board member and Advisor."

John Dawson, CBE, added: "I am excited that this will be my final deal as CEO of the Group. This transaction not only brings proven, scalable, high-quality AAV manufacturing capabilities to Oxford Biomedica, which was in line with our strategy, but also expands Oxford Biomedica’s presence into the US and brings us a dedicated team in close geographic proximity to other leading gene therapy companies in Boston and more widely across the US."

Overview of Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business

Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business comprises Homology’s end-to-end high performing AAV process development and manufacturing platform with a proprietary ‘plug and play’ model protected by IP, and an experienced team of approximately 125 Boston based technical operations employees with deep AAV development and manufacturing know-how.

The state of the art AAV manufacturing facility based near Boston includes approximately 25,000 sq. ft of GMP space for drug substance, drug product, QC testing, quality and warehousing, with three 500L single-use bioreactors. The facility has been operating for GMP production since 2019 and has the potential to expand laboratories and the GMP footprint on-site.

Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business has manufacturing capabilities for both process and analytical development and early stage clinical manufacturing at 500L with proven scalability to 2,000L for commercial supply. The GMP facility has an estimated steady state annual maximum capacity of 10 – 15 500L batches and 10 – 15 1,000L batches. Oxford Biomedica Solutions’ process development expertise covers all AAV related gene therapy and gene editing development functions which has already supported three successful Phase I trial initiations in the United States. Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business will be Oxford Biomedica’s global manufacturing and innovation business for AAV and the focus of Oxford Biomedica’s US operations.

Oxford Biomedica Solutions will at completion of the Transaction have approximately US$35 million (£26 million) worth of AAV CDMO gross assets transferred to it by Homology and is expected to generate a minimum first twelve months contracted revenues of approximately US$25 million (£19 million) from Homology under the three-year Manufacturing and Supply Agreement.

Oxford Biomedica Solutions has not traded as an independent entity to date. Oxford Biomedica expects Oxford Biomedica Solutions to break-even on an EBITDA basis by year 3 after closing with gold standard long term target margins.

Oxford Biomedica Solutions will bring together complementary cultures focused on science-led solutions and excellence in customer service under the leadership of Tim Kelly, Chief Operating Officer of Homology, who will join Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business as Chief Executive Officer and Chair of the Board of Directors and also become a member of Oxford Biomedica’s Senior Executive Team.

Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business employees are integral to the success of the Transaction and will be provided with an attractive incentivisation package upon completion of the Transaction.

Strategic Rationale for the Transaction

The Board of Oxford Biomedica believes that the Transaction has compelling strategic and financial rationale, with the potential to deliver substantial benefits to patients, customers, shareholders and other stakeholders. In particular, the Transaction will:

· Broaden Oxford Biomedica’s viral vector capabilities into the largest and fast growing AAV segment via a single transaction

o Bring fully established manufacturing AAV technologies, IP, capabilities and capacity into Oxford Biomedica

o Offer the opportunity to leverage commercial capabilities in Oxbox in the UK through increased credibility in AAV with Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business

· Expand Oxford Biomedica’s geographic presence with the addition of technical operational expertise near Boston, US presenting ideal access to the key US biopharma hub

o Increase Oxford Biomedica’s total addressable market

o Unlock strong synergy opportunities from the combination of technical capabilities and the ability to cross-sell to existing Oxford Biomedica customers

· Enable Oxford Biomedica to leverage proprietary technologies protected by IP in AAV to further enhance Oxford Biomedica’s existing platform

o Promote a collaborative and complementary AAV and lentiviral vector-based approach across transfection, upstream and downstream, analytical testing and cell technology

o Enhance Oxford Biomedica’s ability to offer solutions that meet the CMC challenges that gene and cell therapy companies face

· Be immediately accretive to revenue growth with contribution from Homology and potential new customers

o The three-year strategic partnership with Homology for AAV manufacturing provides Oxford Biomedica Solutions its first major customer with availability of capacity for potential new customers

In summary, the Transaction accelerates Oxford Biomedica’s strategy to create a leading partner of choice with advanced capabilities across key viral vector types in gene and cell therapy (lentivirus, adenovirus and AAV) that will be able to address the increasing market requirements for efficacy, safety and affordability in cell and gene therapeutics. The enlarged Oxford Biomedica will leverage its strong track record, skills and expertise in a significantly larger total addressable market and provide solutions for gene and cell therapy developers underpinned by technologies, know-how and IP with continued focus on innovation to further enhance the combined platform and its customer offering.

The Transaction will also provide expanded manufacturing capacity to Oxford Biomedica. Oxford Biomedica currently has five manufacturing and R&D facilities (>150,000 sq. ft) in the UK, with the potential for at least four additional GMP suites to be added to existing capacity within its current facilities. Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business will add one process R&D and manufacturing facility (approximately 25,000 sq. ft) in Boston, US with the potential to expand laboratories and the GMP footprint on-site.

Proposed Placing

Oxford Biomedica is undertaking (i) a Firm Placing with certain existing shareholders and other institutional investors of up to 4,858,410 Firm Placing Shares (equating to 5.6 per cent. of the Company’s existing issued share capital as at the last practicable date prior to this Announcement), utilising the unused authorities granted at the 2021 AGM to issue Ordinary Shares for cash on a non-pre-emptive basis and (ii) subject to shareholder approval, a Conditional Placing with certain existing shareholders and other institutional investors of a further number of new Ordinary Shares to be issued under the new authorities to be sought at the General Meeting to issue Ordinary Shares for cash on a non-pre-emptive basis, such that the total gross proceeds from the Firm Placing and the Conditional Placing together reach an amount of approximately £80 million.

Peel Hunt LLP ("Peel Hunt") and WG Partners LLP ("WG Partners") (together the "Joint Bookrunners") are acting as joint bookrunners in connection with the Placing.

The Joint Bookrunners of the Placing reserve the right to issue additional Placing Shares..

The Firm Placing is not conditional on completion of the Transaction and does not require shareholder approval. The Conditional Placing is conditional on completion of the Transaction and on shareholder approval of the issue of the Conditional Placing Shares at the General Meeting. Both the Firm Placing and the Conditional Placing are conditional on Admission becoming effective and the placing agreement between the Company and the Joint Bookrunners (the "Placing Agreement") not being terminated in accordance with its terms.

The Placing will be conducted through a bookbuilding process (the "Bookbuild"), which will be launched immediately following this announcement (such announcement and its appendices together being the "Announcement") and is subject to the terms and conditions set out in Appendix 1 to this announcement. The Joint Bookrunners will commence the Bookbuild and the book will open immediately following the release of this Announcement. The price per Ordinary Share at which the Placing Shares are to be placed (the "Placing Price") and the number of Placing Shares will be determined at the close of the Bookbuild and announced as soon as reasonably practicable after such time. The timing of the closing of the book, the number of Placing Shares to be issued and allocations are at the absolute discretion of the Joint Bookrunners and the Company. The results of the Placing and the Placing Price will be announced as soon as practicable after the close of the Bookbuild. The Placing is not being underwritten. The Placing Shares, if issued, will be fully paid and will rank pari passu in all respects with the existing issued Ordinary Shares of the Company, including, without limitation, the right to receive all dividends and other distributions declared, made or paid in respect of the Ordinary Shares after Admission.

As part of the Placing, there will be an offer made by the Company on the PrimaryBid platform of new Ordinary Shares (the "Retail Offer Shares") at the Placing Price (the "Retail Offer"), to provide retail investors with an opportunity to participate in the equity fundraise. A separate announcement will be made regarding the Retail Offer and its terms. The total number of new Ordinary Shares to be issued pursuant to the Placing and the Retail Offer will be such that no publication of a prospectus by Oxford Biomedica under the UK Prospectus Regulation or the EU Prospectus Regulation is required.

Oxford Biomedica acknowledges that it is seeking to issue new Ordinary Shares on a non-pre-emptive basis and therefore members of its Board of Directors and senior management have consulted with the Company’s major institutional shareholders ahead of the release of this Announcement. Given the benefits of the Transaction, the Company believes the structure, including the issue of new Ordinary Shares on a non-pre-emptive basis, is very much aligned with shareholder and other stakeholder interests. The Placing structure has been chosen as it reduces both the complexity, cost and time of a pre-emptive offering such as an open offer. The consultation has confirmed the Board’s view that the Placing is in the best interests of shareholders, as well as wider stakeholders in the Company and will promote the success of the Company.

This Announcement should be read in its entirety. In particular, you should read and understand the information provided in the "Important Notices" section of this Announcement. The Appendix to this Announcement sets out further information relating to the terms and conditions of the Placing. Unless otherwise stated, capitalised terms in this Announcement have the meanings ascribed to them in the Appendix (which forms part of this Announcement).

Investors who have chosen to participate in the Placing, by making an oral or written offer to acquire Placing Shares, will be deemed to have read and understood this Announcement in its entirety (including the Appendices) and to be making such offer on the terms and subject to the conditions herein, and to be providing the representations, warranties, agreements, acknowledgements and undertakings contained in Appendix 1.

Applications will be made for the Firm Placing Shares and the Conditional Placing Shares to be admitted to the premium listing segment of the Official List (the "Official List") of the Financial Conduct Authority (the "FCA") and to be admitted to trading on the main market for listed securities of London Stock Exchange plc (the "London Stock Exchange") (together, "Admission").

Settlement for the Firm Placing Shares and Admission is expected to take place on or around 8.00 a.m. (London time) on or around 4 February 2022 (or such later time and/or date as the Joint Bookrunners may agree with the Company), and dealings in the Firm Placing Shares will commence at that time. The Firm Placing is conditional upon Admission becoming effective and the placing agreement between the Company and the Joint Bookrunners (the "Placing Agreement") not being terminated in accordance with its terms in respect of the Firm Placing Shares. The Firm Placing is not conditional on completion of the Transaction.

Settlement for the Conditional Placing Shares and Admission is expected to take place on or around 8.00 a.m. (London time) on or around 11 March 2022 (or such later time and/or date as the Joint Bookrunners may agree with the Company), and dealings in the Conditional Placing Shares will commence at that time. The date for Admission of the Conditional Placing Shares is subject to the time it takes for the HSR requirements to be satisfied and the date that the Company posts a circular to its shareholders to convene the General Meeting. When the Company posts the circular to shareholders it will confirm any changes to the timetable for Admission of the Conditional Placing Shares.

Short Term Loan Facility

On 28 January 2022, the Company entered into a commitment letter and a fee letter with funds managed by Oaktree, for a senior secured term loan facility in an aggregate principal amount of US$85 million (£64 million).

The Company and Oaktree intend to enter into definitive agreements for the Facility on or prior to completion of the Transaction and it is expected that the definitive agreements will include: (i) usual and customary mandatory prepayments, covenants and representations and warranties, (ii) a financial covenant requiring the Company and its subsidiaries to maintain a minimum level of liquidity (iii) usual and customary events of default and (iv) customary expense reimbursement and an indemnity from the Company for the benefit of Oaktree against any losses that Oaktree or its indemnified persons may suffer or incur in certain circumstances.

The proceeds of the Facility can be used by the Company, together with the Company’s existing cash, to finance a portion of the purchase price of the Transaction, pay transaction costs and for working capital and general corporate purposes. The availability of the Facility will be subject to the satisfaction by the Company of certain conditions precedent, including the Transaction having been, or being concurrently with the initial borrowing under the Facility, completed in all material respects in accordance with the Equity Securities Purchase Agreement. The Company intends to draw down the Facility to fund a portion of the purchase price of the Transaction.

The Facility will mature twelve months after the date of completion of the Transaction and will not amortise, with the full aggregate principal amount of the Facility being repayable on the final maturity date. The Company intends to repay some or all of the drawn funds out of the proceeds of the Placing.

The Facility will be secured by substantially all of the present and subsequently acquired assets of the Company and its wholly owned subsidiaries and be guaranteed by the Company’s wholly owned subsidiaries, with customary exceptions. The interest rate under the Facility will be 8.50 per cent. per annum, payable quarterly in cash or in kind as additional loan principal, at the option of the Company. Voluntary prepayment and mandatory prepayment of the Facility (including upon acceleration thereof) will be subject to scaling exit fees on the principal amount of loans repaid, ranging from 0% to 0.75% depending on the date of repayment.

Use of Proceeds

As at 31 December 2021 the Company had unaudited cash balances of approximately £109 million, as detailed above the Company has also entered into a commitment letter for short term debt financing of US$85 million (£64 million) with Oaktree which it expects to receive (net of transaction fees and expenses) concurrently with completion of the Transaction. Subject to Admission of the Firm Placing Shares, the net proceeds of the Firm Placing will also be available to the Company prior to completion of the Transaction.

At completion, the net proceeds of the Firm Placing, the Short Term Facility and the Company’s current cash balances will allow the Company to acquire the 80 per cent. ownership interest in newly-formed Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business for a US$130 million (£97 million) cash consideration payable to Homology and a US$50 million (£37 million) capital injection into Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business to fund growth. Should the Firm Placing not complete, then the Company would propose to utilise the Facility and its existing cash resources to fund the Transaction.

The net proceeds of the Firm Placing, the Conditional Placing, the Facility and any other surplus funds after completion of the Transaction will fund the Company’s existing capital requirements in respect of Oxbox and Windrush Innovation Centre (estimated at £65 million), cover the expenses of the Transaction, the Placing and the Facility and provide additional working capital for the Group.

In the event that the Firm Placing completes but the Transaction does not the Company will retain the net proceeds for working capital and general corporate purposes.

The Company estimates that upon completion of the Transaction and the Placing it will hold cash balances of approximately £100 million assuming full draw down of the US$85 million (£64 million) Facility. The Facility is expected to mature within 12 months from the date of completion of the Transaction. This estimated cash balance of £100 million excludes the cash balance associated with the US$50 million (£37 million) working capital injection into Oxford Biomedica Solutions’ AAV Manufacturing and Innovation Business at Completion.

Related Party Transactions

Novo Holdings A/S, a strategic investor in the Company ("Novo Holdings") has indicated its intention to subscribe for approximately £10 million in aggregate across the Firm Placing and the Conditional Placing. Due to Novo Holdings having held more than 10 per cent. of the Company’s issued share capital in the last twelve months, Novo Holdings is deemed to be a related party of the Company under Listing Rule 11.1.4A. As the Placing is not being conducted on a pre-emptive basis and due to the proposed size of Novo Holdings’ participation, the issue of Placing Shares to Novo Holdings would be classified as a related party transaction under the Listing Rules and, as such, the Company may be required to obtain Shareholder approval for the participation of Novo Holdings in the Placing and/or comply with the additional provisions of Listing Rule 11.1.10. If Shareholder approval is required pursuant to Listing Rule 11.1.7, relevant details will be set out in the circular to be sent to Shareholders in connection with the Conditional Placing. The Company will ensure that in the event that Novo Holdings is allocated Firm Placing Shares that the value of any such shares does not trigger the requirement for a Shareholder vote under Listing Rule 11.1.7. If Shareholder approval is required for part of Novo Holdings’ participation and if the relevant resolution is not passed in respect of the participation in the Placing by Novo Holdings, Peel Hunt and WG Partners will use reasonable endeavours to reallocate the Placing Shares originally allocated to Novo Holdings on closing of the bookbuilding process, in accordance with the terms of the Placing Agreement and the terms and conditions set out in Appendix 1.

Dr. Roch Doliveux, the Company’s Chairman and interim CEO, has indicated his intention to invest not less than £1 million in the Placing. Due to his position as director of the Company, Dr. Roch Doliveux is also deemed to be a related party of the Company under Listing Rule 11.1.4A. Therefore, depending on the final number of Placing Shares that Dr. Roch Doliveux may conditionally subscribe for in the Placing, the Company may be required to comply with additional provisions of Listing Rule 11.1.10.
