Research & development

Next Generation pre|CISION(R) pipeline

   -- AVA6103 (FAP-Exd) 
 
          -- Preliminary preclinical and clinical data with AVA6103 have been 
             presented recently. Data reported in the Phase 1a trial in 
             patients with select solid tumors demonstrate proof of mechanism 
             with two key findings: 
 
                 -- AVA6103 pre|CISION(R) controlled-release exatecan 
                    demonstrates a clean safety profile through the first three 
                    dose levels, including a payload dose level 50% higher than 
                    the maximum tolerated dose $(MTD)$ of conventional exatecan 
                    at dose level 3, and 
 
                 -- The comparison of the preclinical modeled pharmacokinetic 
                    (PK) data and clinical trial PK data demonstrates an 
                    exceptional alignment through the first 3 dose levels with 
                    controlled release of exatecan evident in patients for days 
                    after dosing 
          -- The first head-to-head preclinical comparison of AVA6103 and 
             Enhertu(R), a marketed antibody drug conjugate (ADC) that targets 
             HER2, demonstrates that AVA6103 shows better antitumor activity 
             vs. Enhertu(R), with deep and durable responses delivered by our 
             dose dense regimen that has been applied in the FOCUS-01 trial. 
 
          -- Updated preclinical pharmacology and exposure data analyses, 
             highlighting the favorable delivery profile, presented at the 
             American Association for Cancer Research (AACR) Annual Meeting 
             2026. 
 
          -- Comparative analyses of pre|CISION(R) payload delivery preclinical 
             pharmacokinetics (PK) via AVA6103, compared with now two approved 
             ADCs (Enhertu(R) and Datroway(R)), presented at the Company's 
             Science Day, showing the clear advantages of pre|CISION(R) over 
             traditional ADCs. 
 
          -- U.S. Food and Drug Administration (FDA) granted clearance of the 
             Investigational New Drug (IND) application for AVA6103 in January, 
             2026 and the first patient was treated in the trial in March, 
             2026. 
   -- AVA6207 (Dual Payload) 
 
          -- Presented first in vivo efficacy and exposure pharmacology for the 
             pre|CISION(R) dual payload technology program at AACR 2026. 
 
          -- Presented updated in vivo studies of the dual payload delivery 
             system AVA6207 at Science Day. 

pre|CISION(R) platform and First Gen (AVA6000)

   -- Reported data validating the pre|CISION(R) PDC platform, with AVA6000 in 
      patients with salivary gland cancer, where robust tumor responses are 
      observed with low expression of fibroblast activation protein (FAP) and 
      the persistence of FAP expression despite tumor response. 
 
   -- Published new data demonstrating the favorable delivery profile and 
      advantages of pre|CISION(R) compared to a marketed antibody drug 
      conjugate (ADC) 
 
   -- AVA6000 (Faridoxorubicin, pending partnering) 
 
          -- Presented updated Phase 1a/1b data showing encouraging early 
             efficacy signals for AVA6000 in salivary gland cancers at the 2026 
             American Society of Clinical Oncology (ASCO) Annual Meeting. 
 
          -- At the end of Phase 1 meeting, certain pivotal trial elements and 
             the regulatory path forward with Phase 1b data were agreed with 
             the U.S. Food and Drug Administration (FDA) for potential full 
             regulatory approval. 
 
          -- Agreed updates with the FDA to the ongoing Phase 1 trial protocol 
             including the removal of the maximum dosing limit and to allow 
             flexibility in dosing levels to identify the dose for further 
             development. 

Financial

Strengthened financial position to support R&D programs:

   -- Completed oversubscribed placing and subscription, raising GBP10 million 
      (March 2026), and raised gross proceeds of approximately GBP9 million in 
      an equity fundraise (June 2026), from institutional investors and 
      existing shareholders. 
 
   -- Today, separately announcing a proposed capital raise to further 
      strengthen the balance sheet 
   -- Cash and short-term deposit balances at June 30, 2026, of GBP20.27 
      million (31 December 2025: GBP16.9 million million). As of August 31, 
      2026, cash held was GBP10.59 million. 

Corporate

Strengthened leadership and corporate governance via Board appointments:

   -- Richard Hughes as non-executive Chairman (June 2026) 
 
   -- Patrick Vink as Deputy Chairman (in July 2026) 
 
   -- Mats Blom as Chair of the Audit Committee (in September 2026) 

Outlook 2026 and beyond

   -- The design of the FOCUS-1 trial of AVA6013 and preclinical updates were 
      presented in Trials in Progress presentations at both the American 
      Association of Cancer Research (AACR) Conference on Pancreatic Cancer, 
      being held on September 25-28, 2026, and the European Society for Medical 
      Oncology (ESMO) Congress, being held on October 23-27, 2026. 
 
   -- First efficacy data from the FOCUS-01 trial with AVA6103 is anticipated 
      to be presented in H1 2027 -- including data from clinical tumor biopsies 
      which are anticipated to confirm AVA6103 is being retained in a 'drug 
      reservoir' in the tumor, based on the preliminary Phase 1 data. 
 
   -- The selection of the payloads and data to support clinical candidate 
      selection for the Dual Payload Next Gen Program (AVA6207) will be 
      presented in Q4 2026. 
 
   -- Clinical data from the First Gen faridoxorubicin (AVA6000) program will 
      also be presented in Q4 2026 at the ESMO Congress, Oct 23-27, 2026. 

Christina Coughlin, CEO of Avacta, commented:

"This has been a transformative first half for Avacta, with compelling clinical validation of our pre|CISION(R) platform delivering robust and durable tumor responses and demonstrating the clear advantages of our approach over conventional ADCs. The controlled-release mechanism of our Next Gen pipeline with AVA6103 as the lead asset is now working in patients, exactly as modelled, and we are moving towards initial efficacy data in 2027.

"This progress is underpinned by a strong and complementary leadership team. We have further reinforced the expertise and governance at Avacta with several senior appointments in 2026 to management and our Board, who bring the benefit of their scientific, industry, markets and financial acumen to the Company as we advance our proprietary pipeline and explore partnering opportunities to maximize the potential of our pre|CISION(R) platform.

"Our financing activities have raised approximately GBP19.0 million in 2026 to date, which together with the anticipated proceeds of our planned capital raise being launched today, will ensure funding is in place to execute on multiple value inflection milestones, including the efficacy data on AVA6103 in H1 2027, as well as payload selection for our dual-payload program AVA6207 later this year."

About Avacta - https://avacta.com/

Avacta Therapeutics is a clinical-stage life sciences company expanding the reach of highly potent cancer therapies through its proprietary pre|CISION(R) platform. pre|CISION(R) is a payload delivery system based on a tumor-specific protease (Fibroblast Activation Protein or FAP) that is designed to concentrate highly potent payloads in the tumor microenvironment while sparing normal tissues. Avacta's innovative pre|CISION(R) peptide drug conjugates (PDC) are a novel entry to the XDC drug class, leveraging the success of antibody drug conjugates with alternative methods of delivery beyond antibodies.

Our pre|CISION(R) PDCs leverage this tumor-specific release mechanism in a small molecule format to provide unique benefits over traditional antibody drug conjugates (ADC), releasing active payload in the tumor and reducing systemic exposure and toxicity which enables dosing to be optimized to deliver the best outcomes for patients. The lead clinical program is AVA6103, a Next Generation FAP-enabled controlled release pre|CISION(R) version of exatecan that delivers the payload directly in the tumor with limited peripheral blood exposure and is currently in clinical development as a treatment for tumor types sensitive to exatecan including cervical cancer, HR+ breast cancer, small cell lung cancer, gastric cancer, colorectal cancer and pancreatic cancer.

About FAP-Exd (AVA6103)

AVA6103 is the second clinical candidate and is the first asset in the pipeline based on the Next Generation innovative pre|CISION(R) controlled release mechanism that provides for prolonged release of payload directly in the tumor, minimizing systemic exposure. AVA6103 is being evaluated in the FOCUS-01 Phase 1 trial (FAP-Exd in Oncologic Cancers with Unmet needS). Preclinical data suggest this approach has optimized payload delivery with a high intratumoral concentration and prolonged exposure of released payload in the tumor, coupled with limited systemic exposure to the released payload.

Interim report

Strategic overview

We are making excellent progress in the development of our unique pre|CISION(R) technology platform, pioneering a novel, differentiated class of pre|CISION(R) -based medicines to revolutionize drug delivery.

Our platform technology demonstrates multiple advantages over conventional therapeutics by addressing one of the primary challenges of effective treatment of diseases, specifically the balance between efficacy and safety. pre|CISION(R) -based medicines are specifically designed to be silent (inert) in the bloodstream and in the tissues, and to only activate once in the tumor.

We are confident in Avacta's ability to partner preCISION(R) across a number of modalities and in the management team's ability to secure the requisite funding to progress the pre|CISION(R) platform through multiple value driving events.

pre|CISION(R) - our proprietary technology

The challenge in oncology is that the most effective therapies cause the most toxicity in normal tissues. The ability to deliver the active drug directly to the tumor is the promise of our proprietary pre|CISION(R) platform. Avacta's innovative pre|CISION(R) peptide drug conjugates (PDC) are a novel entry to the XDC drug class, leveraging the success of antibody drug conjugates with alternative methods of delivery beyond antibodies.

The key aspect of pre|CISION(R) peptide drug conjugate (PDC) technology is that the conjugated drug (the combination of the oncology drug and our peptide) is inert. It is incapable of entering cells and killing until the peptide is specifically released when it comes into contact with common tumor-associated protein, known as fibroblast activation protein or FAP, in the tumor.

When a pre|CISION(R) PDC encounters FAP in the tumor, the peptide is cleaved and the active payload is released. The release of the payload from the pre|CISION(R) compound in the tumor results in higher concentration of the drug at the tumor and lower blood and healthy tissue levels than would be achievable with standard systemic administration. Importantly, the increased toxicities (payload) at the tumor are directly associated with the pre|CISION(R) medicines.

Two factors that dictate the antitumor potential of pre|CISION(R) medicines are (1) the expression of FAP in the tumor to cleave the peptide (the amount of the FAP protein that exists in the tumor) and (2) the inherent susceptibility of the associated tumors to the chemotherapy (chemicals in the drug) that is released.

We believe that pre|CISION(R) can deliver higher drug levels within tumors which will lead to improved antitumor activity while reducing systemic toxicities. This will dramatically impact the therapeutic index and efficacy of a given anticancer drug. We have observed this with our first clinical program, faridoxorubicin. This program has demonstrated a dramatic reduction in the toxicities associated with conventional doxorubicin and is delivering exciting preliminary efficacy data.

To further extend the pipeline, Avacta has invented the Next Generation Controlled Release pre|CISION technology that adds a chemical capping group and linker with two key advantages: (1) greater control over the release of the payload in the tumor, allowing optimized pharmacokinetic delivery even with payloads that have challenging PK properties, and (2) implementing the linker technology opens a large number of payloads that can be delivered with Next Gen pre|CISION, permitting a full exploration of the landscape opportunity of pre|CISION with 90% FAP expression among solid tumors.

Programs

Our pre|CISION(R) PDCs leverage this tumor-specific release mechanism in a small molecule format to provide unique benefits over traditional antibody drug conjugates (ADC), releasing active payload in the tumor and reducing systemic exposure and toxicity which enables dosing to be optimized to deliver the best outcomes for patients. The lead clinical program is AVA6103, a Next Generation FAP-enabled controlled release pre|CISION(R) version of exatecan that delivers the payload directly in the tumor with limited peripheral blood exposure and is currently in clinical development as a treatment for tumor types sensitive to exatecan including cervical cancer, HR+ breast cancer, small cell lung cancer, gastric cancer, colorectal cancer and pancreatic cancer.

Our first generation asset, Faridoxorubicin (AVA6000) continues in Phase 1b. We anticipate presenting data in October, 2026, at the European Society for Medical Oncology (ESMO) meeting from the cohort of patients with salivary gland cancer. This program is intended to go forward within a partnership and discussions are ongoing regarding such an arrangement.

AVA6207 is our Next Gen Dual Payload program which is on track for the goals, in 2H 2026, of naming of the two payloads that will be included in the molecule and clinical candidate selection. Clinical candidate selection is based on the preclinical pharmacology, chemical properties of the molecule with initial assessment of manufacturing for use in the clinic. These data will be presented in the fourth quarter of 2026.

Outlook

Avacta continues to build our value proposition and our unique world-class scientific and clinical capabilities. Our data are robust and building and industry interest in our innovative platform continues to increase. We are very excited about the next stages of Avacta's journey with the recent clinical data demonstrating proof of mechanism for AVA6103 in the clinic demonstrating the potential in the Next Gen pre|CISION platform. Our upcoming data catalysts demonstrate the progress made in the programs, including the presentation of the FOCUS-01 trial and updated preclinical work with AVA6103, our updated Farodoxorubicin data being presented in October at ESMO, and the payloads and clinical candidate selection in the Next Gen pre|CISION Dual Payload program in the fourth quarter of 2026.

Financial Review

Revenue

Revenues from continuing operations for the six months ended 30 June 2026 were GBP0.06 million (H1 2025: GBP0.06 million; FY 2025: GBP0.113 million).

Revenues from discontinued operations for the six months ended 30 June 2026 was GBPnil million (H1 2025: GBP6.10 million; FY 2025: GBP6.20 million).

Research costs and selling, general and administrative costs

Research costs relate predominantly to the clinical and pre-clinical development work of the pre|CISION(R) therapeutics programs as planned increased to GBP9.69 million (H1 2025: GBP7.20 million; FY 2025: GBP18.76 million).

Other costs and charges

Depreciation from continuing operations decreased to GBP0.56 million (H1 2025: GBP0.73 million; FY 2025: GBP1.27 million). Amortization expense remained at GBP0.01 million (H1 2025: GBP0.01 million; FY 2025: GBP0.01 million).

The share of the costs from the AffyXell joint venture was GBP0.26 million (H1 2025: GBP0.19 million; FY 2025: GBP0.45 million). The share of losses reflects the Group's 21% ownership share of the losses accumulated in the year. The Group investment remained at 21%.

Share-based payment charges were GBP0.54 million (H1 2025: GBP0.74 million; FY 2025: GBP2.13 million).

Operating loss

The Group's operating loss from continuing operations decreased to GBP13.91 million (H1 2025: GBP14.18 million; FY 2025: GBP29.89 million).

Convertible bond costs

During the period, the Group made interest-only cash repayments of GBP0.66 million in accordance with the amended bond terms and settled a further GBP1.20 million of the debt component through an early equity conversion.

The Board continues to consider each settlement event as it arises, taking into account a range of factors including the Company's cash runway, shareholder dilution and broader business prospects.

The bond agreement contains embedded derivatives in conjunction with an ordinary host debt liability. Accordingly, the convertible bonds are presented in the Consolidated Statement of Financial Position as two separate components: 'Convertible bond - debt' and 'Convertible bond - derivative'. The derivative element is measured at fair value using a Monte Carlo option pricing model.

The derivative element was revalued as at 30 June 2026 to GBP3.29 million (30 June 2025: GBP0.27 million; 31 December 2025: GBP2.79 million). After taking account of the GBP0.37 million reduction arising from the early conversion, this resulted in a GBP0.87 million charge recognised in profit or loss in the period (H1 2025: GBP1.01 million credit; FY 2025: GBP1.51 million debit).

The debt element of the bond increased to GBP15.77 million (H1 2025: GBP18.17 million; 31 December 2025: GBP13.36 million). The movement primarily reflects a non-cash interest expense of GBP3.46 million and a GBP0.82 million loss arising from revisions to expected future cash flows, partially offset by GBP0.66 million of interest-only cash repayments and an early conversion of GBP1.20 million. As of 30 September, the outstanding loan balance is GBP12.00 million.

Loss for the period

The reported loss from continuing operations after taxation was GBP19.02 million (H1 2025: GBP16.13 million; FY 2025: GBP36.26 million).

The basic loss per share from continuing operations was 4.23p (H1 2025: 4.23p; FY 2025: 9.07p).

The basic loss per share from discontinued operations was nil (H1 2025: 3.82p; FY 2025: 0.59p).

Cash flow

The Group reported cash and cash-equivalent balances of GBP20.27 million (30 June 2025: GBP12.65 million; 31 December 2025: GBP16.86 million). Cash and cash-equivalents were GBP10.59 million as of 31 August 2026.

There was a cash outflow from operations and working capital movements of GBP15.69 million (H1 2025: GBP12.33 million; FY 2025: GBP24.93 million) and cash outflow from investing activities was GBP0.02 million (H1 2025: inflow of GBP8.77 million; FY 2025: inflow of GBP9.90 million, reflecting the proceeds of the sale of Launch and Coris).

Cash inflow from financing activities, being net proceeds from the issue of share capital and share options, net of the principal elements of lease payments amounted to GBP17.76 million (H1 2025: inflow of GBP0.67 million; FY 2025: inflow of GBP15.64 million). The cash inflows for H1 2026 and FY 2025 related to equity fundraising.

Financial position

Net assets as at 30 June 2026 were GBP3.77 million (30 June 2025: GBP0.14 million; 31 December 2025: GBP2.48 million) of which cash and cash equivalents amounted to GBP20.27 million (30 June 2025: GBP12.65 million; 31 December 2025: GBP16.86 million).

Right-of-use assets amounting to GBP0.63 million (30 June 2025: GBP1.77 million; 31 December 2025: GBP1.32 million) are recognized in relation to the Group's leasehold properties, together with a corresponding lease liability of GBP0.80 million (30 June 2025: GBP1.97 million; 31 December 2025: GBP1.55 million).

Intangible assets decreased to GBP1.55 million (30 June 2025: GBP1.83 million; 31 December 2025: GBP1.55 million) due to amortization of intangible assets.

Liabilities in relation to the unsecured senior convertible bonds issued in October 2022 result in a fair value of the derivative element of GBP3.29 million (30 June 2025: GBP0.27 million; 31 December 2025: GBP2.79 million). The convertible bond debt element at 30 June 2026 was GBP15.77 million (30 June 2025: GBP18.17 million; 31 December 2025: GBP13.36 million).

With current committed expenses, current cash runway takes the Group into early first quarter of 2027.

Events after the reporting period

In July 2026 the Company received an accelerated payment notice from the convertible bond holder in respect of the January 2026 quarterly deferred convertible bond repayment, as referenced most recently in the financing announced on 5 June 2026, which the Company has elected to settle in cash. Accordingly, the Company has settled the accelerated quarterly amortization payment of GBP3.67 million representing principal of GBP2.4 million together with the associated interest and fees payable in the deferment.

In September 2026 the Company received an accelerated payment notice from the convertible bond holder in respect of the April 2026 quarterly deferred convertible bond repayment, which the Company elected to settle in cash. Accordingly, the Company has settled the accelerated quarterly amortization payment of GBP2.613 million, representing principal of GBP2.4 million together with the associated interest and fees payable in the deferment. Following the cash settlement of the April 2026 quarterly deferred convertible bond repayment, both deferred payments have now been satisfied.

As announced on 1 September 2026, the Board of Directors granted share options under the Company's Equity Share Option Scheme incentive plan ("ESOS") to all members of the Management Team (the "Options"). The Options are exercisable at an exercise price of 69 pence per share, being the mid-market closing price of the Company's Ordinary Shares on 27 August 2026, the last trading date before the Options were granted.

As announced on 14 September 2026, Mats Blom, an experienced biotechnology finance executive and Board member with a strong track record as Chief Financial Officer in several life sciences companies, was appointed as a member of its Board of Directors and Chair of the Audit Committee.

Notes to the unaudited condensed consolidated financial statements

for the 6 months ended 30 June 2026

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 as at and for the 6 months ended 30 June 2026 ("interim financial statements") comprise the Company and its subsidiaries (together referred to as 'the Group').

The interim financial statements for the 6 months ended 30 June 2026 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 2025, 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 2025 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 2025 ('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 Group's operations and results are not impacted by seasonal fluctuations.

The Board approved these interim financial statements for issue on 29 September 2026.

Going concern

The Financial Statements have been prepared on a going concern basis. The Company's going concern assessment has been performed as part of the Group's going concern assessment.

During the six months ended 30 June 2026, the Group reported a loss from continuing operations of GBP19.0 million and incurred net cash used in operating activities of GBP15.7 million.

As at 30 June 2026, cash and cash equivalents were GBP20.3 million. The Group has external borrowings in the form of a convertible bond, with a principal amount outstanding of GBP19.2 million as at 30 June 2026.

During the six months ended 30 June 2026, the Group completed equity placings and subscriptions raising gross proceeds of GBP19.0 million. During the period, the Group also made an interest-only cash repayment of GBP0.7 million in respect of the convertible bond and a partial conversion resulted in the derecognition of GBP1.2 million of the host debt liability.

The Group continues to advance its clinical trials and generate successful data and expects to report further findings in late 2026 and early 2027. Following the data, the Group will evaluate partnering and out-licensing opportunities.

The Group faces significant risks associated with successful execution of its strategy. These risks include, but are not limited to technology and product development, introduction and market acceptance of new products and services, changes in the marketplace, liquidity, competition from existing and new competitors which may enter the marketplace and retention of key personnel. As a clinical stage oncology business, the Directors anticipate operating losses to continue for the foreseeable future due to, among other things, costs related to research funding, growth plans and further development of our technology.

The Directors have considered detailed cash flow forecasts that extended to 31 December 2027, which is at least twelve months from the date of approval of these financial statements ("the going concern period"). The forecasts indicate that we currently have enough cash to fund our planned operations into early first quarter of 2027. The forecasts consider current and future economic conditions that are expected to prevail over the period. These forecasts include assumptions regarding the timing and quantum of investment in the therapeutic development programs together with various scenarios which reflect growth plans, opportunities, risks and mitigating actions. The Board is focused on both the short-term and long-term financing strategy to achieve the company goals including obtaining additional funding through the capital markets.

The forecast therefore shows the Group and the Parent Company are dependent on raising funds to advance their key projects and investments to remain cash positive during the going concern period. There are currently no agreements in place and there is no certainty that funds will be raised within the appropriate timeframe. This indicates that a material uncertainty exists that may cast significant doubt on the Group and the Parent Company's ability to continue as a going concern, and therefore they may be unable to realise their assets and discharge their liabilities in the normal course of business.

However, the directors have a reasonable expectation that the required funding will be forthcoming. As a result, the directors believe that the Group and the Company will continue as a going concern for a period of at least 12 months from the date of approval of these financial statements and have therefore prepared the financial statements on a going concern basis.

The financial statements do not include any adjustments that would result from the basis of preparation being inappropriate.

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, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to estimates are recognised prospectively.

The significant judgements made by management in applying the Group's accounting policies and the key sources of estimation uncertainty are consistent with those disclosed in the Group's annual financial statements for the year ended 31 December 2025.

The accounting policies applied in these interim financial statements are consistent with those applied in the Group's consolidated financial statements for the year ended 31 December 2025. A number of new standards and amendments became effective from 1 January 2026 but have not had a material impact on the Group's financial statements.

3) Segmental reporting

Operating segments - continuing operations

In the view of the Board of Directors, the Group has one (2025: one) reportable segment in continuing operations: Therapeutics. Segment reporting has been presented on this basis for continuing operations. The Directors recognise that the operations of the Group are dynamic and therefore this position will be monitored as the Group develops.

The principal activity of Therapeutics is the development of novel cancer therapies harnessing proprietary technology.

The previous second reportable segment as the diagnostics division which is currently under a divestment strategy and being held for sale. All reporting for this segment will be presented as discontinuing operations.

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.

The Group's revenue to destinations outside the UK amounted to 100% (2024: 100%) of total revenue. The revenue analysis below is based on the country of registration of the customer:

 ------------  ----------  ----------  -------------- 
 

During the six month period ended 30 June 2026, there were no transactions with a single external customer that exceeded 10% of the Group's revenue, being GBP56,000.

During the six month period ended 30 June 2025, there were no transactions with a single external customer that exceeded 10% of the Group's revenue, being GBP56,000.

During the year 31 December 2025, transactions with one external customer in the Therapeutics segment amounted individually to 10% or more of the Group's revenues from continuing operations, being GBP113,000.

6) Convertible bond

In October 2022, the Group issued senior unsecured convertible bonds (the "Bonds") with a principal value of GBP55.0 million to a fund advised by Heights Capital Ireland LLC. The Bonds were issued at 95% of par, generating net proceeds of GBP52.25 million after placement fees, and bear interest at a fixed coupon of 6.5% per annum, payable quarterly in arrears.

The Bonds have a maturity of five years and include conversion and settlement features that allow repayment in either cash or ordinary shares of Avacta Group plc, at the Group's option, subject to the contractual terms of the instrument. The Bonds also contain conversion rights permitting the bondholder to convert all or part of the outstanding balance at specified times during the term.

The convertible bond is accounted for as a hybrid financial instrument comprising a host debt liability and an embedded derivative representing the equity-linked conversion and settlement features. The host debt liability is measured at amortised cost while the embedded derivative is measured at fair value through profit or loss. The embedded derivative is valued using a Monte Carlo option pricing model and is classified as a Level 3 fair value measurement under the IFRS fair value hierarchy.

On 20 October 2025, amendments to the terms of the Bonds became effective. The amendments were assessed under IFRS 9 and determined to represent a substantial modification of the liability. Accordingly, the original host debt liability was derecognised and a new host debt liability was recognised at fair value. The embedded derivative remained bifurcated from the host debt liability and continues to be measured separately at fair value through profit or loss.

During the six months ended 30 June 2026, the Group made an interest-only repayment of GBP0.66 million in cash. In addition, a partial conversion of the Bonds resulted in the derecognition of GBP1.20 million of host debt liability and GBP0.37 million of derivative liability, with the corresponding amounts recognised within share capital and share premium. During the period, the carrying amount of the host debt liability was adjusted to reflect revisions to expected future cash flows arising from changes to the repayment profile, including the acceleration of a previously deferred repayment into July 2026. This resulted in a charge of GBP0.82 million, which has been recognised within Gain/(loss) on modification of financial liabilities in the Consolidated Statement of Profit or Loss.

At 30 June 2026, the carrying amount of the host debt liability was GBP15.77 million (30 June 2025: GBP18.17 million; 31 December 2025: GBP13.36 million) and the carrying amount of the derivative liability was GBP3.29 million (30 June 2025: GBP0.27 million; 31 December 2025: GBP2.79 million). Interest expense recognised in respect of the host debt liability during the period amounted to GBP3.46 million (H1 2025: GBP3.87 million; FY 2025: GBP6.98 million). The remeasurement of the derivative liability resulted in a GBP0.87 million loss recognised in profit or loss during the period (H1 2025: GBP1.01 million gain; FY 2025: GBP1.51 million loss).

Events during the six months ended 30 June 2026

   -- On 13 May 2026, a partial conversion of the Bonds resulted in the 
      settlement of GBP1.20 million of the host debt liability through the 
      issue of ordinary shares. The associated derivative liability of GBP0.37 
      million was also derecognised and recognised within equity. 

Events following the six months ended 30 June 2026

   -- In July 2026 the Company received an accelerated payment notice from the 
      convertible bond holder in respect of the January 2026 quarterly deferred 
      convertible bond repayment, as referenced most recently in the financing 
      announced on 5 June 2026, which the Company has elected to settle in 
      cash. Accordingly, the Company has settled the accelerated quarterly 
      amortization payment of GBP3.67 million representing principal of GBP2.4 
      million together with the associated interest and fees payable in the 
      deferment. 
 
   -- In September 2026 the Company received an accelerated payment notice from 
      the convertible bond holder in respect of the April 2026 quarterly 
      deferred convertible bond repayment, which the Company has elected to 
      settle in cash. Accordingly, the Company has settled the accelerated 
      quarterly amortization payment of GBP2.613 million, representing 
      principal of GBP2.4 million together with the associated interest and 
      fees payable in the deferment. Following the cash settlement of the April 
      2026 quarterly deferred convertible bond repayment, both deferred 
      payments have now been satisfied.
