STRATEGIC REPORT
FOR THE PERIOD ENDED 31 DECEMBER 2025

The Directors present their strategic report of the Company for the 5 month period ended 31 December 2025.

Business review
 
The results for the period and the financial position of the Company are shown as in the annexed financial statements. This is a transitional five month period covering 1 August 2025 to 31 December 2025, following the change of ownership and change of accounting reference date. Comparisons with the prior 18-months period ended 31 July 2025 should be treated with caution given the significant difference in period length.

Turnover for the five-month period ended 31 December 2025 was £10,161,799 (versus £24,671,858 for the 18-month period in the previous period). This reflects the continued increase in the volume of clinical trials placed by sponsors in the UK, following the slowdown experienced during 2024 which was driven by extended application processing times at the Medicines and Healthcare products Regulatory Agency (MHRA). The recent improvement in MHRA processing times has contributed to the recovery in activity levels.

The Company earned income from a broad range of customers, as in the previous period. 

Staff salaries and pension costs on a pro-rated monthly basis were 6% lower than in the prior period, reflecting operational efficiencies achieved under new ownership.

The Company is liquid and remains free of debt. The Company has not declared any dividends to shareholders. Net Assets have increased by 7.9% 
(18 month period to 31 July 2025 - down by 6.3%) driven primarily by the profit generated in the period. 

On 1 August 2025, NN Bidco Pty Ltd (as part of the "Nucleus Network" group) completed the acquisition of Hammersmith Medicines Research Limited (HMR). The transaction establishes Nucleus Network as the only early-phase provider with dedicated facilities across Australia, the United States, and the United Kingdom, creating a truly global platform for clinical development. 

The combined organisation offers sponsors a fully integrated model that pairs global reach with deep local expertise. The expanded geographic footprint broadens access to more diverse volunteer and patient populations, supports faster recruitment, and strengthens data quality through the integration of HMR's scientific heritage with Nucleus Network's advanced infrastructure and digital capabilities. 

The Company continues to face global competition for its services, and cost is a major determinant of where sponsors place their trials. The Company aims to maintain its strong reputation for the timely completion of Phase 1 trials, to an excellent standard, in order to keep winning new business. 

Future developments

Following the completion of the acquisition by NN Bidco Pty Ltd on 1 August 2025, the Company is now operating as part of the wider Nucleus Network group. Over the coming year, the Directors' focus will be on integrating HMR's operations within the group, providing sponsors with seamless access to a unified early phase clinical trial platform spanning the United Kingdom, the United States and Australia. 

The Directors anticipate continued growth in the Company's trial pipeline, building on the increase in trial placements observed during 2025 as MHRA processing times have improved. Investment will be directed towards enhancing the Company's clinical and digital infrastructure, expanding patient and healthy-volunteer recruitment capability, and maintaining the Company's reputation for the timely delivery of high-quality early phase clinical trial studies. The Directors are confident that the Company is well-positioned to benefit from the renewed momentum in UK early-phase clinical research and from its participation in the wider Nucleus Network platform.

STRATEGIC REPORT (CONTINUED)
FOR THE PERIOD ENDED 31 DECEMBER 2025

Principal risks and uncertainties
 
The Company's income depends on the research and development expenditure of the international pharmaceutical industry. There is a risk to the business from inflation, as our quotations for medium and long-term projects can quickly become outdated. However, the UK has a strong reputation for high-quality, early-phase clinical research, and benefits from its forward-thinking, pragmatic, and supportive regulator (the MHRA). International sponsors further benefit from the weakness of the pound. Furthermore, HMR has a proven track record of adapting quickly to regulatory change. We will devote all necessary resources to ensure the continued success of our clinical trials.

The Company must comply with UK Clinical Trials Regulations in order to obtain approval for clinical trials from the MHRA and Research Ethics Committees. Also, sponsors of our trials have their own exacting standards with which we must comply. The MHRA and our sponsors audit us frequently for compliance with the regulations for Good Clinical Practice and Good Manufacturing Practice. Failure to comply could have a detrimental impact on the financial performance of the Company.

Serious injury or death of a subject could severely affect the Company. Our staff are trained in the appropriate management of medical emergencies.

We handle sensitive personal and medical data of subjects, so the UK General Data Protection Regulation poses a financial risk to the Company. However, the directors are satisfied that the Company has robust systems in place to mitigate such risks. We have suitably qualified and trained staff, a Quality Management System, a Quality Assurance group, a Data Protection Officer, and a Data Privacy Committee. We have 24-hour cybersecurity monitoring contracts with trusted providers, and certification of compliance with the ISO 27001 Information Security Management standard.

Section 172(1) Statement
 
The Directors have regarded the following considerations of section 172 (1) of the Companies Act, when fulfilling their duty to promote the success of the Company:

The long-term consequences of any decision, by consultation with internal management and external advisers, e.g.:

- Internal meetings of senior managers and managers; 
-  Access to external advice on employment law; 
-  Internal Data Privacy Committee, Information Management Security Officer, and Data Protection Officer; 
-  Internal Health and Safety Committee, including Health and Safety Manager, Fire Wardens, Radiation      Protection Officers, and Biological Safety Officer, and external legal advisers. 

The interests of the Company's employees, by promoting robust HR and training policies: 

-  Company policies on training and on all aspects of discrimination and grievance; 
-  Dedicated training team raising awareness of the above during induction and beyond.

The need to foster the Company's business relationships with suppliers, customers and others, by ensuring that our contracts with customers and subcontractors require all parties to comply with applicable regulations and law. 

The impact of the Company's operations on the community and the environment, by minimising waste and recycling whenever possible.

DIRECTORS' REPORT
FOR THE PERIOD ENDED 31 DECEMBER 2025

The Directors present their report and the financial statements for the 5 month period ended 31 December 2025.

Change of ownership

On 1 August 2025, 100% of the shares in the Company were acquired by NN Bidco Pty Ltd (ACN 623 536 247), an Australian proprietary limited company. As a condition of the sale, the shares in the former subsidiaries, Trio Medicines Limited and Hammersmith Medicines Research (Properties) Limited, together with intercompany balances, were transferred to the former owner, Dr M J Boyce in advance of the above sale. Accordingly, the Company no longer has any subsidiaries and these financial statements are prepared on a company-only basis. This is the first period of account under the new ownership.

Principal activity

The principal activity of the Company in the period under review was that of testing products developed by the pharmaceutical industry.

Hammersmith Medicines Research (HMR) is a contract clinical research organisation (CRO) that conducts studies of new and existing medicines in healthy human volunteers (Phase 1) and in patients (Phase 2), on behalf of the international pharmaceutical industry. The Company intends to continue and grow this work in the future. 

Policy regarding disabled persons
HMR has a disabled workers policy to give equal opportunities for disabled people to enter and progress within the Company. All staff must follow this policy, encourage others to follow it, and report any incident of discrimination. New staff are told about the policy during induction training and are asked to reread the policy each time it is reviewed and reissued. Applications for employment by disabled persons are always fully considered, bearing in mind the respective aptitudes and abilities of the applicant concerned. In the event of members of staff becoming disabled, every effort is made to ensure that their employment with the Company continues and the appropriate training is arranged. It is the policy of the Company that the training, career development and promotion of a disabled person should, as far as possible, be identical to that of a person who does not suffer from a disability. 

Employee consultation
HMR places considerable value on the involvement of its employees and has continued to keep them informed on matters affecting them as employees and on the various factors affecting the performance of the Company. The Company achieves this through regular directors' meetings, managers' meetings, team meetings and through consultation with employee representatives.

Research and development
The Company's research and development expenditure for the 5 months period totalled £4,709,456 (18 months ended 31 July 2025 - £22,471,825).

Results and dividends

The profit for the period, after tax, amounted to £1,280,125 (18 months ended 31 July 2025 - loss £1,091,049).

No dividends will be distributed for the 5 month period ending 31 December 2025 (18 months ended 31 July 2025 - £Nil).

DIRECTORS' REPORT (CONTINUED)
FOR THE PERIOD ENDED 31 DECEMBER 2025


Directors

The following Directors held office during the whole of the period from 1 August 2025 to 31 December 2025 and up to the date of this report:

G K Wood (appointed 1 August 2025) 
T J Pisarev (appointed 1 August 2025) 
M J Boyce (resigned 1 August 2025)
S J Warrington (resigned 1 August 2025)
 
Financial instruments

The Company has a normal level of exposure to price, credit, liquidity and cash flow risks arising from trading activities.

Price risk
The Company carefully monitors costs incurred from suppliers and constantly reviews the pricing of its services to ensure that margins remain favourable.

Credit risk
The risk of financial loss due to third parties failing to honour their obligations arises where the Company provides services to customers. The Company has implemented policies to minimize such losses and require that terms are only granted to customers who meet the internal requirements for having suitable payment history and adequate creditworthiness.

Liquidity risk
The Company manages daily the cost requirements and is not reliant on external borrowing. Following the acquisition by Nucleus Network in August 2025, the group's enlarged scale provides greater financial certainty and support for the Company's operations.

Cash flow risk
The Company maintains cash reserves to meet all of its costs. Following the acquisition by Nucleus Network, the Company benefits from being part of a larger global group, providing additional assurance that sufficient cash reserves are maintained to support ongoing requirements.

DIRECTORS' RESPONSIBILITIES STATEMENT
FOR THE PERIOD ENDED 31 DECEMBER 2025

The Directors are responsible for preparing the Strategic Report, the Directors' Report and the financial statements in accordance with applicable law and regulations.

Company law requires the Directors to prepare financial statements for each financial year. Under that law the Directors have elected to prepare the financial statements in accordance with applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice), including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland'. Under company law the Directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the Company and of the profit or loss of the Company for that period.

 In preparing these financial statements, the Directors are required to:

∙select suitable accounting policies for the Company's financial statements and then apply them consistently;

∙make judgements and accounting estimates that are reasonable and prudent;

∙state whether applicable UK Accounting Standards have been followed, subject to any material departures disclosed and explained in the financial statements; and

∙prepare the financial statements on the going concern basis unless it is inappropriate to presume that the Company will continue in business.

The Directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company's transactions and disclose with reasonable accuracy at any time the financial position of the Company and to enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the Company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HAMMERSMITH MEDICINES RESEARCH LIMITED
 

Opinion


We have audited the financial statements of Hammersmith Medicines Research Limited (the 'Company') for the 5 month period ended 31 December 2025 which comprise the Statement of Comprehensive Income, Balance Sheet, Statement of Changes in Equity, Statement of Cash Flows and the notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (United Kingdom Generally Accepted Accounting Practice).

In our opinion, the financial statements:
∙give a true and fair view of the state of the Company's affairs as at 31 December 2025 and of its profit for the period then ended;
∙have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
∙have been prepared in accordance with the requirements of the Companies Act 2006.


Basis for opinion


We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.


Conclusions relating to going concern


In auditing the financial statements, we have concluded that the Directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.


Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.


Our responsibilities and the responsibilities of the Directors with respect to going concern are described in the relevant sections of this report.

Other information


The other information comprises the information included in the Annual report and financial statements, other than the financial statements and our auditor’s report thereon. The Directors are responsible for the other information contained within the Annual report and financial statements. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.


Opinions on other matters prescribed by the Companies Act 2006
 

In our opinion, based on the work undertaken in the course of the audit:


∙the information given in the Strategic Report and the Directors' Report for the financial period for which the financial statements are prepared is consistent with the financial statements; and
∙the Strategic Report and the Directors' Report have been prepared in accordance with applicable legal requirements.


Matters on which we are required to report by exception
 

In the light of the knowledge and understanding of the Company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Directors’ Report. 

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:
∙adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
∙the financial statements are not in agreement with the accounting records and returns; or 
∙certain disclosures of Directors’ remuneration specified by law are not made; or 
∙we have not received all the information and explanations we require for our audit.


Responsibilities of directors
 

As explained more fully in the Directors’ responsibilities statement set out on page 6 the Directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the Directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Directors are responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HAMMERSMITH MEDICINES RESEARCH LIMITED (CONTINUED)

Auditor's responsibilities for the audit of the financial statements
 

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities. including fraud, is detailed below:

We obtained a general understanding of the Company’s legal and regulatory framework through enquiry of management concerning their understanding of relevant laws and regulations, the entities’ policies and procedures regarding compliance, and how they identify, evaluate and account for litigation claims. We also drew on our existing understanding of the Company’s industry and regulation.

We understand that the Company complies with the framework through: 
∙The Directors' close involvement in the day-to-day running of the business, meaning that any litigation or claims would come to their attention directly; and
∙The engagement of external experts to achieve ongoing tax compliance and to assist with the preparation of the statutory accounts.

In the context of the audit, we considered those laws and regulations which determine the form and content of the financial statements, which are central to the Company’s ability to conduct its business and where there is a risk that failure to comply could result in material penalties. We identified the following laws and regulations as being of significance in the context of the Company:
∙The Companies Act 2006 and FRS 102 in respect of the preparation and presentation of the financial statements; and
∙UK Taxation Law; and
∙Human Medicines Regulations 2012; and
∙Medicines For Human Use (Clinical Trials) regulations 2004 with compliance under the Medicines and Healthcare products Regulatory Agency guidelines; and
∙General Data Protection Regulation (GDPR).

We performed the following specific procedures to gain evidence about compliance with the significant laws and regulations identified above:
∙Obtaining management representations regarding the adequacy of procedures in place;
∙Inspecting any correspondence with regulatory authorities in relation to the above areas;
∙Making enquiries to management regarding any significant matters arising or potential litigation; and
∙Reading the minutes of meetings of those charged with governance.

The senior statutory auditor led a discussion with senior members of the engagement team regarding the susceptibility of the Company’s financial statements to material misstatement, including how fraud might occur.

The areas identified in the discussion were:
∙The risk that management may be incentivised to overstate revenue, particularly in relation to year end cut off; and
∙Manipulation of the financial statements to increase revenue and/or profits via fraudulent journal entries.

These areas were communicated to the other members of the engagement team not present at the discussion.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE PERIOD ENDED 31 DECEMBER 2025

1.


General information

Hammersmith Medicines Research Limited is a private company, limited by shares, domiciled and incorporated in England and Wales (registered number: 02779946). The registered office address is 44 Cumberland Avenue, London, NW10 7EW.

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and the Companies Act 2006.

The preparation of financial statements in compliance with FRS 102 requires the use of certain critical accounting estimates. It also requires management to exercise judgement in applying the Company's accounting policies (see note 3).

The following principal accounting policies have been applied:

 
2.2

Going concern

The financial statements have been prepared on a going concern basis.

Background

On 1 August 2025, 100% of the shares in the Company were acquired by NN Bidco Pty Ltd (ACN 623 536 247), an Australian proprietary limited company. This is the first period of account under the new ownership. The current period is a transitional five month period from 1 August 2025 to 31 December 2025.

Assessment

The Directors have prepared detailed cash flow forecasts for a period of at least twelve months from the date of approval of these financial statements. The forecasts reflect the Company's current trial pipeline, anticipated revenues from contracted and forecast studies, expected operating costs and known capital expenditure commitments.

Based on these forecasts, the Directors are satisfied that the Company has sufficient liquidity and financial resources to continue its operations and meet its liabilities as they fall due for the foreseeable future. This assessment is supported by the Company's strong financial position, with no external debt and cash balances of £5.4 million at the balance sheet date. Accordingly, the Company is considered able to operate as a stand-alone entity without reliance on financial support from its parent undertaking.

While the new parent undertaking has both the intent and the ability to provide financial support if required, the Directors have concluded that such support is not necessary for the Company to continue as a going concern. Therefore, the financial statements have been prepared on the going concern basis.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE PERIOD ENDED 31 DECEMBER 2025

2.Accounting policies (continued)

  
2.3

Revenue recognition

Revenue comprises the fair value of the consideration received or receivable for the provision of services in the ordinary course of the Company's activities. Turnover is shown net of value added tax and rebates.

Revenue is attributable to testing products developed by the pharmaceutical industry. Revenue is invoiced at staged intervals when certain conditions are met during a particular study, as determined by the contract with the sponsor. At the completion of the particular study, a final reconciliation is undertaken to ensure that revenue is complete.

Revenue is recognised as project activity progresses on a stage of completion basis.

Since the Company undertakes all phases of medical research as and when required by customers they are included together as continuing operations in the statement of comprehensive income.

Where stage payments are received from sponsors in advance of services provided, the amounts are recorded as deferred income and included as part of creditors: amounts falling due within one year. Furthermore, where project activity exceeds invoices raised to date, the amounts are recorded as accrued income within debtors: amounts falling due within one year.

  
2.4

Research and development

Research and development expenditure is written off to the statement of comprehensive income in the year in which it is incurred.

 
2.5

Interest income

Interest income is recognised in profit or loss using the effective interest method.

 
2.6

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the plan are held separately from the Company in independently administered funds.

HAMMERSMITH MEDICINES RESEARCH LIMITED
 
 
NOTES TO THE FINANCIAL STATEMENTS
FOR THE PERIOD ENDED 31 DECEMBER 2025

2.Accounting policies (continued)

 
2.7

Current and deferred taxation

The tax expense for the period comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the United Kingdom where the Company operates and generates income.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that:
∙The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and
∙Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date.


 
2.8

Exceptional items

Exceptional items are transactions that fall within the ordinary activities of the Company but are presented separately due to their size or incidence.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE PERIOD ENDED 31 DECEMBER 2025

2.Accounting policies (continued)

 
2.9

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using the straight-line method.

Depreciation is provided on the following basis:

Freehold property
-
2%
on cost
Medical equipment
-
20%
on cost
Furniture, fixtures and fittings
-
20%
on cost
Computer and office equipment
-
25%
on cost

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.

 
2.10

Debtors

Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

  
2.11

Cash and cash equivalents

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

 
2.12

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

 
2.13

Provisions for liabilities

Provisions are recognised when an event has taken place that gives rise to a legal or constructive obligation, a transfer of economic benefits is probable and a reliable estimate can be made.

Provisions are measured as the best estimate of the amount required to settle the obligation, taking into account the related risks and uncertainties.
 
Increases in provisions are generally charged as an expense to profit or loss.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE PERIOD ENDED 31 DECEMBER 2025

2.Accounting policies (continued)

 
2.14

Financial instruments

Financial assets and financial liabilities are recognised in the Balance Sheet when the Company becomes a party to the contractual provisions of the instrument.

Trade and other debtors and creditors are classified as basic financial instruments and measured at initial recognition at transaction price. A provision is established when there is objective evidence that the Company will not be able to collect all amounts due.

Cash and cash equivalents are classified as basic financial instruments and comprise cash in hand and at bank, short-term bank deposits with an original maturity of three months or less and bank overdrafts which are an integral part of the Company’s cash management.

Financial liabilities and equity instruments issued by the Company are classified in accordance with the substance of the contractual arrangements entered into and the definitions of a financial liability and an equity instrument. An equity instrument is any contract that evidences a residual interest in the assets of the Company after deducting all of its liabilities. Equity instruments issued by the Company are recorded at the proceeds received, net of direct issue costs.

Interest bearing bank loans, overdrafts and other loans which meet the criteria to be classified as basic financial instruments are initially recorded at the present value of cash payable to the bank, which is ordinarily equal to the proceeds received net of direct issue costs. These liabilities are subsequently measured at amortised cost, using the effective interest rate method.

3.


Judgements in applying accounting policies and key sources of estimation uncertainty

In the application of the Company's accounting policies, which are described above, management is required to make judgements, estimates and assumptions about the carrying values of assets and liabilities that are not readily apparent from other sources. The estimates and underlying assumptions are based in historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both the current and future periods.

In preparing the financial statements, the Directors have made the following significant judgements and estimates that have a material impact on the amounts recognised in the financial statements:

Stage of completion of projects (revenue recognition)

The Company recognises revenue from clinical trial services based on the stage of completion of individual projects in accordance with contractual deliverables agreed with sponsors. Judgement is required in determining the appropriate stage of completion at the reporting date, particularly where multiple deliverables or complex study protocols exist.

Estimation of impairment of tangible fixed assets

The Company reviews the carrying values of its tangible fixed assets for indicators of impairment at each reporting date. Where indicators exist, the recoverable amount of the asset is estimated, being the higher of value in use and fair value less costs of disposal.

FOR THE PERIOD ENDED 31 DECEMBER 2025

3.Judgements in applying accounting policies (continued)

Estimation of the Research and Development Expenditure Credit (RDEC) debtor

The Company recognises a debtor in respect of Research and Development Expenditure Credits (RDEC) relating to qualifying expenditure incurred during the period. The estimation of this balance requires judgement in determining the eligibility of expenditures, the applicable rates under the legislation, and the timing and manner of recovery of the credit.
