About Fusion Antibodies plc

Fusion is a Belfast-based Collaborative Research Organisation ("CRO") company, listed on AIM, providing an integrated end-to-end range of antibody engineering services for the development of antibodies for both therapeutic drug and diagnostic applications.

Fusion provides a broad range of services in antibody generation, development, characterisation, optimisation, and small-scale production. These services include antigen expression, purification and sequencing, antibody humanisation using Fusion's proprietary CDRxTM platform and cell line development, producing antibody generating stable cell lines optimised for use downstream by the customer to produce material for clinical trials. Since 2012, the Company has successfully sequenced and expressed over 250 antibodies and successfully completed over 200 humanisation projects for its international customer base, which has included eight of the top 10 global pharmaceutical companies by revenue.

At every stage, our client's vision is central to how we work in combining the latest technological advances with cutting edge science. In this work our world-class humanization and antibody optimization platforms harness the power of natural somatic hypermutation (SHM) to ensure the best molecule goes to the clinic. Fusion Antibodies' growth strategy is based on enabling Pharma and Biotech companies get to the clinic more effectively, using molecules with optimized therapeutic profile and enhanced potential for successful development and approval and, ultimately, on speeding up the drug discovery and development process. The announced Integrated Therapeutic Antibody Services ("ITA") offering will enhance the efficiency of this process by providing a continuous service offering from target nomination to stable cell line. Fusion's use of SHM to create a fully human antibody library to capture the human antibody repertoire will address a continuing market need in antibody discovery.

Fusion Antibodies' emphasis on antibody therapeutics is based on the size and growth rate in the sector, with the market valued at $135.4 billion in 2018 and forecast to surpass $300 billion by 2025, a CAGR of 14.26%. As of May 2021, there were 100 approved antibody therapies on the market and more than 570 antibody therapies in clinical development.

Operational Review

The Company has had a commercially challenging six months to 30 September 2022. In this backdrop, the Company is introducing a new integrated approach in response to client needs and to ultimately increase revenues. The focus for our R&D has continued on the OptiMALTM library project, with investment in R&D increased by 7% over the same period in the previous year.

Revenues for the six-months ended 30 September 2022 were lower than the same period last year, due to a combination of factors. Notably a small number of valuable projects have been suspended by clients due to delayed investment into those businesses. Clients have suggested that we should expect these projects to recommence once their funding is secured. We saw a return to some face-to-face conferences and events in FY2022. However, the effect on new orders from the reduction of contact and lead generation while the Covid-19 pandemic restrictions were in place continues. Alternative measures that were implemented during the exceptional period of travel restrictions did not yield as good as results in comparison to face-to-face meetings due to the highly technical nature of the business.

Demand for our core Humanisation and RAMPTM services has continued to be strong with modest growth in revenues compared with H1 FY2022. Transient gene expression has also performed well. The geographic spread was similar to that for full year FY2022 including business through our Asian-distributors.

In April 2022 a new Head of Commercial activities joined the Company and, as previously announced, the new CEO, Adrian Kinkaid, joined in August this year. They are working together to raise the profile of the Company in our market and promote our services internationally, including Company attendance at eight specialist conferences in Europe and North America between September and December. There has also been a significant restructuring of the Company's commercial team and a curation of the customer relationship management database. We are pleased to note that customer visits to Fusion's laboratories have also recommenced in recent weeks with customers from Japan and USA as well as a team from our partner, Eurofins Discovery.

Integrated Therapeutic Antibody Service ("ITA")

At every stage, our client's vision is central to how we address their project. ITA pulls together all our current services to enhance the efficiency of this process and provide a continuous service from target discovery to a final stable cell line ready for larger scale production and is consistent with Fusion's established philosophy to "begin with the end in mind". This approach is a natural evolution of the aim to be a research partner with our customer, providing more services and with additional success milestones and royalties arising from such projects. When the OptiMALTM platform is commercially ready it will be incorporated into the ITA.

Research and Development

Additional resources have been invested in R&D and development work on OptiMALTM, the class leading Mammalian Antibody Library, has continued throughout the period. Each stage of the programme has now been validated and work is currently ongoing on extracting and evaluating antibodies to oncology targets. We continue to build a body of data with a view to establishing commercial relationships for further validation by the end of the financial year.

To maintain our position at the forefront of the antibody sector we take advantage of technological advances in the delivery of our existing services. This involves in-house innovation, continuing professional development of our scientific staff and periodic updating of our equipment.

Financial Review

Revenues for the six-month period ending 30 September 2022 were £1.86 million (H1 FY2022: £2.44 million). Included in the H1 FY2022 revenues was the one-off £150,000 milestone with no milestones received in H1 FY 2023. The Company continues to retain an interest of a future success milestone or royalty in 13 client

projects. The revenues of £1.86 million represents a reduction from the underlying £2.3 million revenues in H1 FY2022.

The 33% gross profit percentage on underlying revenues was lower than in the same period last year due to an under-utilisation of available capacity for fee generating projects (H1 FY2022: 46%), some of the spare capacity being deployed to support the internal R&D efforts.

R&D expenditure in H1 FY2023 was £452,000, an increase of 7% over the comparable period in FY2022 reflecting the continuing investment particularly in in the OptiMALTM Library project.

SG&A expenditure of £1,419,000 was £53,000 lower than in H1 FY2022 due in part to professional fees incurred in the previous period.

Operating loss for the period resulting from the above was £1,256,000 (H1 FY2022: £650,000 loss).

Cash used in operations was £754,000 compared with £505,000 used in H1 FY2022. The H1 FY2023 operational outflow includes the £452,000 investment in R&D. The Company continues to hold elevated levels of consumable stocks to mitigate against current supply chain risks caused by both the COVID-19 pandemic and Brexit. The total outflow was £851,000 and the closing cash balance at 30 September 2022 was £1,198,000.

Key Performance Indicators

The key performance indicators (KPIs) regularly reviewed by the Board are:

KPI	H1 2023	H1 2022
Underlying revenue growth	(19)%	20%
EBITDA*	(£1.008m)	(£0.275m)
Cash used in operations	(£0.754m)	(£0.505m)
* Earnings before interest, tax, depreciation and amortisation

The investment in R&D and the impact on EBITDA is set out in Note 12 to these statements. EBITDA for the period was a loss of £1,008,000 (H1 FY2022: £275,000 loss) and adjusting for research and development expenditure shows an EBITDA loss excluding R&D of £556,000 for the period (H1 FY2022: £149,000 profit).

Outlook

In the Company's Annual Report 2022 we commented on the considerable uncertainty arising from global macro conditions. Events since that date have not eased concerns with political uncertainty and market volatility in the UK along with other global factors, although predictions are suggesting less volatility and reducing inflationary pressures ahead. Challenges remain for our international customer base and we continue to meet these challenges and capitalise on the opportunities presented.

Based on a current assessment of the sales pipeline and as a result of greater lead generation from face-to- face meetings, the Board believe we can deliver an improved performance in H2 and continue to build value in the Company.
