Interim Results for the Period Ending 30 June 2023

A period of substantial clinical progress and continued growth

Avacta Group plc (AIM: AVCT), a life sciences company focused on improving healthcare outcomes through targeted cancer treatments and diagnostics, is pleased to announce its unaudited interim results for the six months ending 30 June 2023 ("H1 2023").

Operating highlights

· Avacta's lead pre|CISION™ programme, AVA6000, a tumour microenvironment activated form of a chemotherapeutic agent, doxorubicin, made significant progress in a Phase 1a clinical trial (ALS-6000-101) during H1 2023, with an excellent safety profile continuing to be observed through the dose cohorts as detailed in the Company's announcements.

· Post period, the sixth dose cohort (310 mg/m2) was successfully completed and escalation to the seventh and final cohort (385 mg/m2) was approved in September, with a significant reduction in tumour volume confirmed in a patient with soft tissue sarcoma.

o  In light of the highly positive Phase 1a data, the Company has adapted its clinical development strategy with the aim of bringing forward the start of a potentially pivotal Phase 2 study, subject to receiving the necessary regulatory approvals.

· Preclinical data regarding AVA3996, the second pre|CISION™ programme, a tumour targeted proteasome inhibitor, were presented at the American Association of Cancer Research Annual Meeting in April, supporting confidence in the potential of this molecule to restrict tumour growth.

· AffyXell Therapeutics ("AffyXell"), the joint venture between Avacta and Daewoong Pharmaceutical ("Daewoong") continued to progress well with the triggering of a second milestone payment. This will result in an increase in Avacta's shareholding in AffyXell to approximately 25% from its current 19%, which will be determined when a formal valuation has been completed as was done for the first milestone payment.

· The Group continues to pursue an M&A-led growth strategy for the Diagnostics Division to support the building of an in-vitro diagnostics product portfolio for professional use, including those against infectious respiratory diseases.

· Avacta's Diagnostics Division completed the acquisition of Belgium-based Coris Bioconcept SRL on 1 June 2023, for an upfront consideration of £7.3 million with an earnout based on future business performance of up to £3.0 million payable in cash, adding a broad range of marketed professional-use rapid tests to the Division:

o  This acquisition supports the strategy of acquiring commercial routes into the diagnostics market and appropriate IP-rich product portfolios, complementing the acquisition of Launch Diagnostics in October 2022 has been successfully integrated into the Diagnostics Division.

o  Adjusted EBITDA loss (before non-cash and non-recurring items) of the Diagnostics Division reduced to £0.4 million (H1 2022: £2.6 million; year ended 31 December 2022: £5.1 million).

Financial highlights

Outlook

The continuing success of AVA6000 in the Phase 1a clinical study is important not only for the potential to improve outcomes for patients with cancers suitable for treatment with doxorubicin, but also as a validation of the pre|CISIONTM platform more widely. The Company aims to complete the AVA6000 three-weekly dose escalation safety study and to provide a detailed data read-out during Q4 2023.

In parallel, the Company will also initiate a fortnightly dosing safety study in order to determine the dosing regimen for a Phase 2 registrational study in soft tissue sarcoma planned to start during 2024, in advance of previous estimates. Subject to positive data, this could potentially bring the first pre|CISIONTM targeted chemotherapy to market for the benefit of patients with soft tissue sarcoma towards the end of 2026.

The Company is progressing pre-clinical programmes based on both the pre|CISIONTM and Affimer® platforms and anticipates providing detailed updates on these programmes in the coming months.

The Group's Diagnostics Division is focused on the integration of its first two acquisitions and finding synergies across the enlarged division. The Group is aiming to grow the Diagnostics Division organically and through geographical expansion into the German market, with the near-term aim of achieving an overall EBITDA positive position.

"Targeting of cancer therapies to tumour tissue has been a long sought after goal for many oncology drug companies, clinicians and patients. There are many potent anti-cancer drugs, the effectiveness of which is limited by the systemic toxicities and lack of tolerability for patients.

"The clinical data emerging for our lead pre|CISIONTM drug, AVA6000, is ground-breaking. We are seeing a dramatic reduction in the usual toxicities associated with anthracycline chemotherapy and we have clear indications that doxorubicin is being released in active form in the tumour microenvironment.

"Across the board we're proud and encouraged by the momentum we're seeing in both divisions of this business and see huge potential value both for patients and investors in the next period."

Dr Alastair Smith, Chief Executive Officer of Avacta Group plc, commented:

"Not only are the initial safety data emerging from the AVA6000 Phase 1 study, across all dose cohorts, remarkably good, but targeted release of doxorubicin in the tumour has been confirmed both by analysis of tumour biopsies and now by clear clinical responses.

"Even at this early stage and in this patient group, we have a confirmed, significant reduction in tumour volume in a patient with soft tissue sarcoma, as well as other positive signals across a number of patients. This excellent progress means that we are aiming to accelerate the timetable for the start of the pivotal Phase 2 efficacy study in soft tissue sarcoma into 2024.

About Avacta Group plc - www.avacta.com

Avacta Group is a UK-based company focused on improving healthcare outcomes through targeted cancer treatments and diagnostics.

Avacta has two divisions: an oncology biotech division harnessing proprietary therapeutic platforms to develop novel, highly targeted cancer drugs, and a diagnostics division, which is executing on an M&A led growth strategy to create a full-spectrum diagnostics business focused on supporting healthcare professionals and broadening access to testing. Avacta's two proprietary platforms, Affimer® and pre|CISIONTM underpin its cancer therapeutics whilst the diagnostics division leverages the Affimer® platform to drive competitive advantage in its markets.

The pre|CISIONTM platform modifies chemotherapy to be activated only in the tumour tissue, reducing systemic exposure and toxicity. This is achieved by harnessing an enzyme called FAP which is highly upregulated in most solid tumours compared with healthy tissues, turning chemotherapy into a "precision medicine". The lead pre|CISIONTM programme, AVA6000 a tumour activated form of doxorubicin, is in Phase 1 studies and has shown dramatic improvement in safety compared with standard doxorubicin, and early signs of clinical activity.

Affimer® is a novel biologic platform which has significant technical and commercial advantages compared with antibodies and is used both to develop advanced immunotherapies and to improve the performance of immunodiagnostics.

With a balanced business and capital allocation model: a high-value oncology pipeline supported by a revenue generating, fast-growing diagnostics business, Avacta seeks to create long-term shareholder value alongside patient benefit.

Chairman and Chief Executive Officer's Statement

Avacta Therapeutics Division Update

Avacta's Therapeutics Division aims to leverage its two proprietary technology platforms, pre|CISION™ and Affimer®, to develop innovative oncology therapies that make a significant difference to cancer patients' treatment experience and outcomes.

AVA6000: a tumour-activated form of doxorubicin

Anthracyclines such as doxorubicin, a generic chemotherapy for which the broader market is expected to grow to $1.38 billion by 2024, are widely used as part of standard of care in several tumour types, but their dosing regimen and long-term use is limited by severe systemic toxicities, in particular, by haematological toxicities and cardiotoxicities.

Avacta's pre|CISION™ tumour-activation platform is designed to reduce the systemic exposure of healthy tissues to the active chemotherapy, leading to improved dosing regimens, improved safety and tolerability for patients and better treatment outcomes.

The ALS-6000-101 Phase 1 clinical trial involves a dose-escalation Phase 1 study in patients with locally advanced or metastatic-selected solid tumours, known to be FAPα-positive, in which cohorts of patients receive ascending doses of AVA6000 initially at three-weekly intervals to determine the maximum tolerated dose. For more information visit www.clinicaltrials.gov (NCT04969835).

Doxorubicin is used as a monotherapy for the treatment of soft-tissue sarcoma ("STS"), a relatively rare mesenchymal malignancy which accounts for less than 1% of adult tumours. Despite the successful advancement of localised therapies such as surgery and radiotherapy, these tumours can recur, often with metastatic disease. The American Cancer Society estimates that in 2022 approximately 13,190 new soft tissue sarcomas were diagnosed and about 5,130 people were expected to die of the disease in the US.

The Phase 1a three-weekly dose escalation study is being carried out at several sites in the UK and United States and is now dosing patients in the seventh and final dose escalation cohort at 385 mg/m2, which is approximately 3.5 times the normal dose of doxorubicin.

The data emerging from the dose escalation study show an excellent safety profile. In the first six completed dose cohorts, AVA6000 has been well tolerated by patients, with a marked reduction in the incidence and severity of the typical toxicities associated with the standard doxorubicin chemotherapy administration. Typical toxicities include alopecia, myelosuppression, nausea, vomiting, mucositis and cardiotoxicity. Importantly, even at the highest dosing levels, equivalent to several-fold higher than the normal dose of doxorubicin, the typical drug-related cardiotoxicity of doxorubicin has not been observed.

Analysis of a number of tumour biopsies obtained from patients in different cohorts has also confirmed the release of the active chemotherapy, doxorubicin, in the tumour tissue. This analysis shows that AVA6000 targets the release of doxorubicin to the tumour tissue at therapeutic levels which are much higher than the levels being detected in the bloodstream at the same timepoint.

Post-period, the Company announced that it had confirmed a significant reduction in tumour size in a patient on the trial with a sub-type of STS in which doxorubicin is expected to be effective. Several other patients have also shown positive responses to the treatment.

Preliminary clinical data on AVA6000 have demonstrated that the pre|CISIONTM modification has resulted in targeted release of the active drug to the tumour microenvironment, dramatically reducing the systemic toxicities being observed in patients and resulting in clinically effective levels of the active drug in the tumour.

In light of AVA6000's continued strong clinical progress, the Company has reviewed its clinical development strategy with the aim of accelerating a pivotal Phase 2 study in STS which could lead to the first regulatory approval for the drug.

The excellent safety profile of AVA6000 opens up the potential to dose patients more frequently, as well as with higher doses or more cycles of treatment. In order to determine the recommended Phase 2 dose, the Company will initiate a short fortnightly dosing study in place of the much longer multi-arm Phase 1b efficacy study previously envisaged.

This fortnightly dosing study should be completed by the middle of 2024 which the Company expects will allow the Phase 2 study to start much earlier than planned, in 2024.

The Company expects to release detailed Phase 1a data in Q4 2023 following completion of cohort 7.

Pipeline of pre|CISION™ chemotherapies

Avacta's pre|CISION™ platform is a proprietary chemical modification that renders the modified chemotherapeutic drug inactive in the circulation until it enters the tumour microenvironment, where it is activated by an enzyme called FAPα. FAPα is in high abundance in most solid tumours but not in healthy tissues.

The data emerging from the AVA6000 Phase 1a study have validated the performance of the pre|CISION™ platform, opening up the opportunity to apply it to a broad range of existing chemotherapies and new, more potent cytotoxins.

The next most advanced pre|CISION™ pre-clinical candidate is AVA3996, a tumour-activated proteasome inhibitor based on an analogue of Velcade. The global proteasome inhibitors' market size is expected to be worth $2.3 billion by 2026 and Velcade represents just over half of that market.

As with all chemotherapies, the benefit of these drugs is limited by toxicities and tolerability for patients. In the case of Velcade, there are significant side effects such as peripheral neuropathy, which has limited its approval, principally in treating multiple myeloma. A potentially safer proteasome inhibitor, such as AVA3996, could be used to treat solid tumours.

During the period, the Company presented pre-clinical data regarding AVA3996 in a poster entitled 'AVA3996, a novel pre|CISION™ medicine, targeted to the tumor microenvironment via Fibroblast Activation Protein-alpha (FAP-a) mediated cleavage', at the American Association for Cancer Research ("AACR") 2023 Annual Meeting. The poster and a video explainer are available on the Company's web site (see https://avacta.com/avacta-presents-ava3996-pre-clinical-data-at-the-american-association-for-cancer-research-meeting/).

The Company is continuing its pre-clinical development of AVA3996 (pre-clinical models of safety, pharmacokinetics and efficacy) with the aim of an investigational new drug ("IND") filing in H2 2024.

Affimer® immunotherapy programmes

Translation of the Affimer® platform into the clinic to demonstrate the safety and tolerability of this novel therapeutic protein platform is an important objective for the Company and represents a key value inflection point for the Affimer® technology.

In the oncology field recent studies have shown that single cancer immunotherapies, or 'monotherapies', have potentially limited overall response rates. The Company's Affimer® immunotherapy strategy aims to harness the benefits of the Affimer® platform to build bispecific drug molecules which can address two drug targets simultaneously, and to use Affimer® molecules to target toxic payloads using conventional and pre|CISION™ linkers.

Whilst the Company is prioritising its pre|CISION™ programmes as the nearest term driver of key value inflection points for both patients and Avacta shareholders, good progress has been made in the in-house Affimer® programmes which, along with the Company's commercial collaborations, are a key part of the in-house research activities.

Avacta will be presenting an update on its lead Affimer® PD-L1/cytokine bispecific programme as a poster presentation at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics (October 11-15, 2023, Boston, USA). This information will be made available on the Company's website following the meeting.

Ongoing Drug Development Collaborations

LG Chem Life Sciences

Avacta has a strategic partnership with LG Chem Life Sciences focused on the development of a novel PD-L1 checkpoint inhibitor utilising the Affimer® platform incorporating Affimer XT® half-life extension. The partnership also provides LG Chem with rights to develop and commercialise other Affimer® and non-Affimer biotherapeutics combined with Affimer XT® half-life extension for a range of indications, and Avacta could earn up to $55 million in milestone payments for each of these new products. In addition, under the agreement Avacta will earn royalties on all future Affimer XT® product sales by LG Chem.

At the end of June 2022, LG Chem exercised its option to renew its rights under the ongoing collaboration with Avacta, triggering a licence renewal fee payment to Avacta of $2 million. LG Chem is focused on progressing the PD-L1/XT oncology drug candidate towards the clinic and has commenced pre-clinical studies which are intended to form the basis of an IND submission.

AffyXell Therapeutics

AffyXell was established in January 2020 by Avacta and Daewoong as a joint venture to develop novel mesenchymal stem cell ("MSC") therapies. AffyXell is combining Avacta's Affimer® platform with Daewoong's MSC platform such that the stem cells are genetically modified to produce and secrete therapeutic Affimer® proteins with immuno-modulatory effects in situ in the patient. The Affimer® proteins are designed to enhance the therapeutic effects of the MSC creating a novel, next generation cell therapy platform.

Avacta has successfully developed and characterised Affimer® proteins against the second target of interest for AffyXell and has filed a patent application for the associated intellectual property triggering the second milestone in the agreement during the reporting period. The second milestone will result in an increase in Avacta's shareholding in AffyXell, which currently stands at 19%. The exact shareholding will be determined, as with the first milestone payment which was achieved in April 2022, following a formal valuation of AffyXell and is expected to be approximately 25%.

POINT Biopharma Inc.

Early in 2021, Avacta signed a licensing agreement with POINT Biopharma Inc. ("POINT"), to provide access to Avacta's pre|CISION™ technology for the development of tumour-activated radiopharmaceuticals.

Avacta Diagnostics Division Update

Avacta's Diagnostics Division is driving ambitious growth through an M&A-led strategy with the aim of supporting healthcare professionals and broadening access to high quality diagnostics. The strategy is founded on acquiring both the routes into the diagnostics market and the appropriate IP-rich product portfolios.

During the reporting period, Avacta completed its second acquisition, Coris Bioconcept SRL ("Coris"), a developer and supplier of rapid diagnostic test kits, for an upfront cash consideration of £7.3 million (on a debt-free/cash-free basis and subject to customary working capital adjustments), with an earnout based on future business performance, payable in cash, of up to £3.0 million.

Coris, based in Gembloux, Belgium and established in 1996, develops, manufactures and markets rapid diagnostic test kits, mainly lateral flow tests, for use by healthcare professionals. Coris is ISO 13485 certified and markets its products through distributors in Europe, Asia, South America, Africa and Oceania.

Operationally, Coris employs 35 members of staff split across Production, Sales, Marketing, Quality Control, Regulation and Administration. In March 2023, the business completed the construction of a new 10,700 ft2 production, offices and warehouse facility in Gembloux.

Coris' product portfolio comprises diagnostic tests for respiratory, gastro-enteric and blood-borne pathogens (bacteria, viruses and parasites) and for the detection of antibiotic resistance markers. Antibiotic resistance is a major global challenge and there are good future growth prospects for the market for antimicrobial resistance ("AMR") testing and is a key area in which Avacta expects to grow the Coris business.

The existing Coris management team have remained with the business and are working closely with Avacta Diagnostics' businesses to drive growth and margins through improved distribution channels and an expanded product range. Avacta will transfer its lateral flow product development activities to Coris and support that activity through ongoing development of Affimer® reagents for new products or to enhance existing ones.

Financial Review

Revenue

Revenue for the 6 months ended 30 June 2023 increased to £11.89 million compared to the same period in 2022 (H1 2022: £5.52 million; year ended 31 December 2022: £9.65 million).

Revenue contribution from the Therapeutics Division was £1.99 million (H1 2022: £5.44 million; year ended 31 December 2022: £5.48 million) due to achieving a further milestone in our collaboration with AffyXell (which leads to additional equity in the joint venture). Revenue from the Diagnostics Division increased to £9.90 million (H1 2022: £0.07 million; year ended 31 December 2022: £4.17 million) as the reporting period included a full six months trading for Launch Diagnostics and one month from the recent acquisition of Coris.

Acquisitions

On 1 June 2023, the Group acquired 100% of the shares and voting interests in Coris. Coris develops, manufactures and markets rapid diagnostic test kits, mainly lateral flow tests, for use by healthcare professionals. Coris is ISO 13485 certified and markets its products through distributors in Europe, Asia, South America, Africa and Oceania. Total consideration for Coris included an initial consideration of £7.31 million on a debt-free / cash-free basis, in addition to a further £2.81 million in relation to customary working capital adjustments, payable in cash upon completion of the acquisition. There is also additional consideration of up to £3.0 million based on revenue exceeding certain targets over the next two financial years. The additional consideration to be paid based on future revenues is estimated to be £1.59 million as at 30 June 2023.

The acquisition of Coris is a further step in the M&A-led growth strategy for the Group's Diagnostics Division, designed to build an integrated and differentiated IVD business with global reach servicing professionals and consumers.

For the period from acquisition to 30 June 2023, Coris contributed revenue of £0.82 million and operating profit of £0.19 million to the Group's results.

Research costs and selling, general and administrative costs

Research costs relating to new diagnostic tests in the Diagnostics Division and the clinical and pre-clinical development work of the Affimer® and pre|CISION™ therapeutics programmes in the Therapeutics Division were £6.01 million (H1 2022: £6.00 million; year ended 31 December 2022: £11.10 million).

Selling, general and administrative costs have increased to £8.65 million (H1 2022: £4.69 million; year ended 31 December 2022: £11.23 million) as the Group expands the Diagnostics Division.

Adjusted EBITDA

The Consolidated Statement of Profit or Loss shows an Adjusted EBITDA loss position (before non-recurring and non-cash items) of £7.91 million (H1 2022: £5.42 million; year ended 31 December 2022: £15.09 million).

Other costs and charges

Depreciation has increased to £1.28 million (H1 2022: £0.88 million; year ended 31 December 2022: £1.90 million). Amortisation expense has remained almost constant at £0.44 million (H1 2022: £0.41 million; year ended 31 December 2022: £1.05 million) with amortisation of acquired intangible assets now comprising the majority of the expense, instead of the comparative period's amortisation of capitalised development costs.

The share of the costs from the AffyXell joint venture in the period was £0.42 million (H1 2022: £0.65 million; year ended 31 December 2022: £1.15 million).

Acquisition related expenses during the period amounted to £0.28 million (H1 2022: £nil; year ended 31 December 2022: £0.74 million).

Share-based payment charges have reduced to £1.55 million (H1 2022: £2.29 million; year ended 31 December 2022: £7.49 million).

Operating loss

The Group's operating loss increased to £11.88 million (H1 2022: £9.65 million; year ended 31 December 2022: £32.65 million).

Convertible bond costs

During the reporting period there have been two quarterly amortisation repayments (of £2.75 million and £2.60 million respectively in equity) and a further early redemption (of £2.85 million in equity) which reduces the original £55.00 million senior unsecured convertible bonds issued in October 2022 at par value to £46.80 million. Subsequent to the period end in July 2023 a third quarterly amortisation of £2.60 million in equity was settled leaving the remaining balance of bonds at par value of £44.20 million. On 20 September 2023, 715,789 new ordinary shares were issued in settlement of £0.85 million of the principal amount of the unsecured convertible bond, reducing the principal remaining to £43.35 million.

The bond agreement contains embedded derivatives in conjunction with an ordinary host debt liability. As a result, the convertible bonds are shown in the Consolidated Statement of Financial Position in two separate components, being 'Convertible bond - debt' and 'Convertible bond - derivative'. The derivative element has been measured at fair value using a Monte-Carlo option pricing model, which estimates the fair value based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the bondholders.

The derivative element, taking into account the amortisations and early redemption, was revalued as at 30 June 2023 at £28.90 million (30 June 2022: £nil; 31 December 2022: £39.10 million), which has resulted in a credit within the period of £5.86 million.

The debt element of the bond has reduced from £18.73 million at 31 December 2022 to £15.68 million at 30 June 2023 (30 June 2022: £nil), with an associated non-cash interest expense of £6.85 million.

Loss for the period

The reported loss from continuing operations after taxation was £11.53 million (H1 2022: £8.99 million; year ended 31 December 2022: £39.54 million).

The basic loss per share from continuing operations was 4.28p (H1 2022: 3.58p; year ended 31 December 2022: 15.48p).

Cash flow

The Group reported cash and cash-equivalent balances of £25.97 million (30 June 2022: £17.02 million; 31 December 2022: £41.78 million).

There was a cash outflow from operations and working capital movements of £11.19 million (H1 2022: £9.43 million; year ended 31 December 2022: £15.95 million) and an outflow from investing activities of £7.35 million from the acquisition of Coris and capital expenditure (H1 2022: inflow of £0.09 million; year ended 31 December 2022: outflow of £25.04 million). Cash outflow from financing activities, being principal elements of lease payments net of amounts received from the exercise of share options amounted to £0.56 million (H1 2022: inflow of £0.37 million; year ended 31 December 2022: inflow of £56.90 million).

Financial position

Net assets as at 30 June 2023 were £22.74 million (30 June 2022: £35.98 million; 31 December 2022: £18.44 million) of which cash and cash equivalents amounted to £25.97 million (30 June 2022: £17.02 million; 31 December 2022: £41.78 million).

The IFRS 16 Leases presentation results in the recognition of a 'right-of-use' asset amounting to £6.18 million (30 June 2022: £4.65 million; 31 December 2022: £5.42 million) in relation to the Group's leasehold properties and other leased assets, together with a corresponding lease liability of £6.10 million (30 June 2022: £4.83 million; 31 December 2022: £5.11 million).

Intangible assets increased to £33.46 million (30 June 2022: £7.50 million; 31 December 2022: £26.32 million) due to the acquisition of Coris and the recognition of a further £7.61 million in goodwill, which is expected to be allocated in part to other intangible assets as a result of the purchase price allocation exercise currently being undertaken.

Liabilities in relation to the unsecured senior convertible bonds issued in October 2022 and subsequent amortisations and redemptions during the period, result in a fair value of the derivative element of £28.90 million (30 June 2022: £nil; 31 December 2022: £39.10 million). The convertible bond debt element at 30 June 2023 was £15.68 million (30 June 2022: £nil; 31 December 2022: £18.73 million).

Notes to the unaudited condensed consolidated financial statements

for the 6 months ended 30 June 2023

1) Basis of preparation

Avacta Group plc ('the Company') is a company incorporated in England and Wales under the Companies Act 2006. These condensed consolidated interim financial statements ('interim financial statements') as at and for the 6 months ended 30 June 2023 comprise the Company and its subsidiaries (together referred to as 'the Group').

The interim financial statements for the 6 months ended 30 June 2023 are unaudited. This information does not constitute statutory accounts as defined in Section 435 of the Companies Act 2006. The financial figures for the year ended 31 December 2022, as set out in this report, do not constitute statutory accounts but are derived from the statutory accounts for that financial year. The statutory accounts for the year ended 31 December 2022 were prepared under IFRS and have been delivered to the Registrar of Companies. The auditors reported on those accounts. Their report was unqualified, did not draw attention to any matters by way of emphasis and did not include a statement under Section 498 of the Companies Act 2006.

The Board confirms that, to the best of its knowledge, these condensed financial statements have been prepared in accordance with IAS34 Interim Financial Reporting and should be read in conjunction with the Group's last annual consolidated financial statements as at and for the year ended 31 December 2022 ('last annual financial statements'). They do not include all of the financial information required for a complete set of IFRS financial statements. However, selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in the Group's financial position and performance since the last annual financial statements. The comparative results for the 6 month period ended 30 June 2022 and the year ended 31 December 2022 include those of a discontinued operation. This relates to the Animal Health segment, which the Group sold in its entirety on 15 March 2022. Further details of this discontinued operation can be found in the financial statements for the year ending 31 December 2022.

The Board approved these interim financial statements for issue on 28 September 2023.

2) Use of judgements and estimates and significant accounting policies

The preparation of the interim financial statements requires management to make judgements and estimates that affect the application of accounting policies and the reported amounts of assets and liabilities, income and expense. Although these estimates are based on management's best knowledge of the amount, events or actions, actual events ultimately may differ from those estimates.

The significant judgements made by management in applying the Group's accounting policies, and the key sources of estimation uncertainty were the same as those described in the last annual financial statements.

The accounting policies applied in these interim financial statements are the same as those applied in the Group's consolidated financial statements as at and for the year ended 31 December 2022. A number of new standards were effective from 1 January 2023 but they do not have a material effect on the Group's financial statements.

3) Segmental reporting

The Group has two distinct operating segments: Diagnostics and Therapeutics. These are the reportable operating segments in accordance with IFRS 8 Operating Segments. The Directors recognize that the operations of the Group are dynamic and therefore this position will be monitored as the Group develops.

Segment revenue represents revenue from external customers arising from sale of goods and services, plus inter-segment revenues. Inter-segment transactions are priced on an arm's length basis. Segment results, assets and liabilities include items directly attributable to a segment as well as those that can be allocated on a reasonable basis.
