# What is an Optimer®?

An Optimer® is a short single-stranded DNA or RNA molecule that can selectively bind to a target.

Optimer® binders are oligonucleotide affinity binders that can function as complementary to, or an alternative to, antibodies. The limitations of antibodies are recognised by the market, but no alternative is readily available. Optimer® binders are offering new solutions within the global market, currently worth over \$170 billion,1 delivering solutions to bioprocessing, diagnostic, and pharmaceutical scientists.

"Excellent technical and commercial progress; a comprehensive cost-base reset; and an acceleration of licensing opportunities will cement Aptamer Group's position as a global leader in line with shareholder expectations."

> I am delighted to have recently taken the role of Non-Executive Chairman at Aptamer Group, With a background in drug development, it is inspiring to be working at the forefront of the cutting-edge innovations and technical advancements the Group is driving across various sectors.

Recent changes over the last twelve months, both within the Company and across the macroeconomic and investment landscape, have encouraged the new Board of Directors to fortify a strategy that aims for three objectives:

- accelerated development of wholly-owned and partnered internal assets:
- revenue maximisation from our fee-for-service work; and,

Dr Adam Hargreaves

Non-Executive Chairman

A key example of this is our ongoing partnership with Unilever, which aims to develop Optimer® binders for the treatment of malodour in personal care products. The fast-moving consumer goods market is a non-exploited territory for aptamer use, and we are excited to partner with the leading global player in this commercially-attractive space.

In more traditional applications, key assets are under development in diagnostics and therapeutics. The Group is working in partnership with Neuro-Bio to develop Optimers to enable the world's first lateral flow tests for the pre-symptomatic diagnosis of Alzheimer's disease. The diagnostic market value for Alzheimer's disease was worth over \$4 billion in 2022,1 and we believe an Optimer-based test could be revolutionary for this disease, as it would allow patients access to treatments earlier, with the potential to halt

These three examples testify to the potential of the technology and skill of our scientific team. Developing new diagnostics and therapeutics in an emerging field is challenging and Aptamer is leading the market in these specific areas.

Of particular note concerning the work undertaken during the past six months has been the soft launch of our Optimer®+ platform. This combines all the advantages of an Optimer® with additional protein constructs akin to protein-based ligands, such as antibodies and bicuclic peptides. Optimer®+ is a wholly-owned and patent-protected technology. Initial contracts for this platform, including from a large pharmaceutical company, have been signed. Following validation and optimisation of the platform, we expect this area of the business to become a key offering.

# Increasing the commercial trajectoru

Commercially, the start of the FY23-24 year was very challenging for Aptamer. The Group experienced a reduction in customer confidence due to the strength of our balance sheet and a downturn in market conditions across the life sciences sector. Despite these factors, extremely proactive work by all employees across the Group has returned confidence in our technology, as methodology and operational advancement have continued apace. Over the year, the Group has seen increasing revenue recognition, with 65% realised in the second half and £1.0 million in orders won in the last quarter.

Tight cost discipline over the last twelve months reduced the cost base from a budgeted £6.4 million per annum at the start of the financial year to £3.6 million per annum as of August 2024. These reductions were achieved through operational headcount, premises, leadership team costs, and overheads. Due to this rightsizing of the business and the successful postperiod fundraise in August 2024, Aptamer can begin to capitalise on its technological and commercial traction, with the security of a significant cash runway.

# **Board Changes**

Since joining Aptamer's Board as a Non-Executive Director in 2023, I have been impressed with the talent and dedication of the entire staff. It has been a privilege to step into the role of Chair as of August 2024. I would like to express mu thanks to former Executive Chairman Steve Hull, who returned to the Group's management team in August 2023 to help successfully reset the business. I would also like to thank Non-Executive Director Dean Fielding, who joined Aptamer in August 2023, for his valued commitment and contribution over the year. Both have been instrumental in reshaping the Group and have now stepped down from the Board as we focus to capitalise on the technical Optimer® assets that have been developed.

Integral to the dynamic shift of direction have been further exciting changes. Aptamer co-founder Dr. Arron Tolley returned to the Group as Chief Technical Officer in August 2023. His technical focus and commercial expertise have been critical in shaping fit-for-purpose product development methods and building a fresh and enthusiastic customer base, keen to explore our technology. Arron has been notable in his ability to create commercial opportunities and maximise the Group's scientific potential. As of August 2024, we welcomed Arron to the role of Chief Executive Officer.

Andrew Rapson has joined the Board of Directors as Chief Financial Officer and Company Secretary in August 2024, and Tim Sykes joined as a Non-Executive Director in September 2024. Andrew brings shrewd financial awareness, foresight, and fiscal prudency to the team, having previously worked with the financial team here at Aptamer. Tim brings a wealth of industrial and economic knowledge, with comprehensive experience in both public and private companies. We welcome them both and look forward to working together.

Dr. David Bunka remains as Chief Scientific Officer of the Group. David is a co-founder of the Company, and his leadership and international reputation have been paramount in rebuilding our network of key clients and solving muriad scientific challenges whenever they have arisen. David is integral to the Group, and we are proud to have him in this role.

# Outlook

The previous twelve months have undoubtedly been challenging at Aptamer. I would like to thank all shareholders, both current and new, who supported us in the latest fundraising, and who continue to support the Company. Following the raise, the Group is now sufficiently well-funded to enable the development of Optimer® assets, crustallising value inflection opportunities over the coming years.

Aptamer's strategic focus going forward is to advance the development of our valued internal assets, and plans are in place with relevant partners to enable this. Unilever intends to move to on-person functionality studies in 2024 for the application of our Optimer® as an active ingredient in deodorants, which will be another key step in the demonstration of our technology. If successful, we anticipate project completion within the next two years, with a potential for licensing. The Group is in multiple discussions with interested parties around the Optimer® delivery vehicle for liver fibrosis. We are delighted to continue the partnership with AstraZeneca and aim to extend the current dataset to encompass in vivo proof-of-concept studies. Such work has the potential to unlock multiple significant high-value deals.

The Board will continue to apply its rigorous cost management principles and has identified up to £0.6 million of further annualised savings. In addition, the Group expects to continue growing the fee-for-service development work, which is important in its objective of being self-sustaining. This work also acts as a horizon-scanning method with which the Group can determine future potential high-value Optimer® assets.

The progress across the Group over the past year has been transformational. I would like to extend our gratitude to all team members at Aptamer. They have displayed admirable enthusiasm, dedication, and commitment to overhauling the business model and maintaining a sharp focus on ongoing projects and activities. They have also been pivotal in growing Aptamer's new innovative scientific and entrepreneurial culture.

In closing, I thank shareholders for their ongoing support and enthusiasm in what we as a Company are trying to achieve.

**Dr Adam Hargreaves** Non-Executive Chairman 21 October 2024

# Opportunity advanced

The tuned target binding and scalable, consistent manufacturing characteristics of Optimer® binders position them as a disruptive technology in the well-established global antibody market.

# Large and growing antibody market

The value of the well-established monoclonal antibody market is estimated at \$111.9 billion per annum (2022).1

It is expected to grow at approximately 6.6% (CAGR) to \$186.7 billion by 2030.1 Current market drivers are cited as an increase in chronic disease and precision medicine pushing demand for novel treatments, along with the patent expiry of many renowned antibodies which will fuel development of new biosimilars to meet the supply gaps of these therapeutics.1

However, whilst it is growing rapidly, it is not without its challenges. Reports suggest that between 50-60% of research antibodies fail to meet their internal research standards, 2 with \$1 billion wasted annually on ineffective antibodies in the research segment alone.3

Antibodies are also costly to manufacture, transport and store. Coupled with the expense, the unethical use of animals in antibody generation is driving demand for alternative, synthetic technologies across research and pharmaceutical sectors.4

# Antibody alternatives bring much needed benefits

Alternative binding approaches, such as the disruptive technologies used by Aptamer, address many of the challenges faced in the antibody market.

Aptamer Group develops Optimer® binders, as an antibody alternative. Optimer® binders are engineered to address many of the issues found with alternative binder technologies, such as antibodies, and offer innovative solutions to bioprocessing, diagnostic and pharmaceutical scientists.

Optimer® binders, as next-generation aptamers, overcome pitfalls in antibody production, manufacture, supply and ethics. The aptamer market is set to expand rapidly over the next decade at over 24% per annum, to a multi-billion dollar worldwide market. 5 Drivers for this market include the increasing recognition of aptamers over antibodies, and the increasing number of clinical trials for aptamer therapeutics.5

Increased recognition of the advantages of the Optimer® platform has driven expansion of the customer base beyond the standard life science applications into the cosmetics/fast-moving consumer goods market.

Our technology is used by customers to develop diagnostic platforms - for example, in proteomics, lateral flow devices, biosensors and immunoassays. These types of diagnostic platforms have applications across human health, environmental services and in the agri-food sector.

The sensitivity of a diagnostic test relies on highperformance binding reagents and the capabilities of the Optimer® platform can be tuned to deliver reagents suitable for diagnostic use. These reagents are central to a test's performance. Optimer® binders are more likely to successfully integrate into a commercially viable diagnostic platform compared to traditionally derived binders, such as antibodies, as they are selected using conditions that mirror the end application

(temperature, environment, sample type, etc). In addition, Optimers' physical properties are beneficial compared to protein-based alternatives making them of specific interest for the diagnostic market. For example, manufacturing of aptamers

is scalable and consistent through solid-phase

storage and there is no need for cold-chain supply. Aptamer Diagnostics has successfully developed diagnostic platforms, including Enzume-Linked

flow cytometry and cell or tissue imaging. We have also demonstrated the use of these binders in several biosensor formats, including BioLauer and Raman spectroscopy-based sensors. Aptamer Diagnostics' revenue model comprises

Aptamer Therapeutics provides contract research services in the field of therapeutics, using our Optimer® platform to develop Optimer®-drug conjugates, Optimer®-enabled gene therapies and Optimer® agonists and antagonists.

The use of Optimer® binders as drug conjugates has generated significant interest from potential pharmaceutical partners focused on the targeted delivery of drug molecules. Delivering drug molecules to specific cells and tissues within the body remains a major translational challenge yet holds the potential to increase the therapeutic index of many drugs. The relatively small size of Optimer® binders compared with antibodies gives them several advantages in tissue penetration and access to binding sites. When coupled with the typically low immunogenic profiles of oligonucleotide-based therapeutics, and comparative ease of synthesis and modification, this creates the potential to use them as novel format targeted delivery vehicles.

# Technology accelerated

"The technical strides made at Aptamer over the last year have supported the reinvigoration of the pipeline and delivered strategic assets that are primed for licensing, affirming our position as a market leader."

Last year, major changes were seen in the aptamer market: in July 2023, Astellas, a pharmaceutical giant, acquired Iveric Bio, a therapeutic aptamer company, for \$5.9BN,¹ followed by FDA approval of the second-ever aptamer therapy in August 2024.² In concert with these milestones, the therapeutic pipeline for aptamers continues to advance and grow through various stages of clinical trials for a range of indications. This increasing maturation of aptamer technology has also been noted across research and diagnostic sectors, where antibodies' shortcomings mean they fail ~50% of the time,³ leading to a requirement for alternatives to fulfil unmet needs.

The rising awareness and exploration of aptamer technology across the life sciences industry has fuelled growth in the market, leading to the emergence of numerous smaller competitors. As a leading global player, Aptamer Group is strategically positioned with unique expertise and advanced development capabilities, creating substantial barriers for other companies attempting to match our pace of innovation and progress.

Administrative costs were £3.2 million for the year compared to £5.0 million for the year to 30 June 2023. This decrease in costs is a result of employee costs reducing to £2.1 million (2023: £3.3 million) and a decrease in operational footprint and consultancy and other administrative costs. The headcount has decreased slightly from 46 at 30 June 2023 to 34 at 30 June 2024. Since the year end, the Group has reduced the cost base by a further £0.3 million.

# **Adjusted EBITDA**

The Group uses adjusted EBITDA as a profit performance metric as this excludes items which can distort comparability of underlying trading as well as being the measure of profit which most accurately reflects the cash generating activities of the Group. The reconciliation of adjusted EBITDA to Operating Loss is on page 37.

In the prior period an impairment loss of £2.6 million was recognised following a review of the carruing value of the cash-generating unit in light of the conditions prevailing as at 30 June 2023. No further impairment of this cash generating unit was considered necessary at 30 June 2024.

# Share-based payment charges

The non-cash charge for the year was £0.49 million (2023: £0.84 million).

# Tax

The Group claims each year for research and development tax credits. Since it is loss-making, the Group elects to surrender these tax losses for a cash rebate. The amount is included within the taxation line of the income statement and amounts to £0.2 million (2023: £0.5 million) and represents a tax loss surrender of £1.9 million. Tax losses carried forward totalled £11.4 million (2023: £9.0 million). The Group has not recognised any tax assets in respect of trading losses arising in the current financial year or accumulated losses in previous financial years.

# Loss for the year

The loss for the year was £3.0 million (2023: £7.8 million loss). The basic loss per ordinary share decreased to 0.71 pence (2023: 11.35 pence per share) based on an average number of shares in issue during the period

## Cash flow

The Group had £0.9 million of cash at 30 June 2024 (2023: £0.2 million). The net cash inflow for the year was £0.6 million (2023: £6.5 million outflow). This reflects a cash outflow from operations of £2.7 million (2023: £4.6 million), a cash inflow from fundraising activities of £3.5 million (2023: £Nil), cash receipts relating to research and development tax credits of £0.5 million which represented the tax refund for the prior period (2023; £0.5 million), payment of leases of £0.5 million (2023: £0.4 million) and an investment in capital expenditure and intangible assets of £0.1 million (2023: £2.0 million). The £2.0 million capital expenditure in the prior year was in relation to the fit out of the new laboratory and office space.

In particular, we looked at where the directors made subjective judgments, for example in respect of significant accounting estimates that involved making assumptions and considering future events that are inherently uncertain. As in all of our audits we also addressed the risk of management override of internal controls, including evaluating whether there was

evidence of bias by the directors that represented a risk of material misstatement due to fraud. How we tailored the audit scope We tailored the scope of our audit to ensure that we performed enough work to be able to give an opinion on the financial statements as a whole, taking into account the structure of the Group and the Company, the accounting processes and controls. and the industry in which they operate.

We performed audits of the complete financial information for Aptamer Group Plc, Aptamer Solutions Limited, Aptamer Diagnostics Limited, Aptamer Therapeutics Limited, Aptasort Limited, which were individually financially significant and accounted for 100% of the Group's revenue and 100% of the Group's absolute loss before tax (i.e. the sum of the numerical values without regard to whether they were profits or losses for the relevant reporting units). The Group engagement team performed all audit procedures.

Material uncertainty related to going concern In auditing the financial statements, we have concluded that the director's use of the going concern basis of accounting in the oreparation of the financial statements is appropriate. We draw upur attention to note 1.3 in the financial statements, which indicates

the key risks and uncertainties set out on page 42 and 43 may affect the future prospects and trading activities of the group. The Group cash receipts in the forecast includes revenues (as further disclosed in note 1.3) and the timely receipt of R & D tax credits and accounts receivables. The directors are satisfied that they would be able to take mitigating action in the event that

the sales growth was slower and that these cash realization's will be met. These conditions, along with other matters as set out in note 1.3 indicate that a material uncertainty exists that may cast significant doubt on the Group's ability to continue as a going

- Engaging with senior management around the group to obtain a broad-based understanding of key commercial drivers:
- Testing the mathematical accuracy of the going concern model prepared by management and the underlying calculations used within it:

- Evaluating the adequacy of disclosures made in the financial statements in respect of poing concern.

Our application of materiality The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures on the individual financial statement line items and disclosures and in evaluating the effect of misstatements, both individually and in aggregate on the financial statements as a whole.

Based on our professional judgment, we determined materiality for the financial statements as a whole as follows: Group financial statements Company financial statements £157,000 (2023: £261,000). £150,000 (2023: £230,000). Overall materiality How we determined it Based on 5% of loss before tax (2023: 5% of Net Based on 5% of Net Loss (2023: 5% of Net Loss). Loss - before impairment loss). Rationale for The most adequate basis is for materiality to be The most adequate basis is for materiality to be based on the net loss, which is consistent with our benchmark applied based on the net loss, which is consistent with our understanding of the cashflows and the Group's understanding of the cashflows and the Company's business model year on year which also considers business model year on year. that there are some trading components in the group.

For each component in the scope of our Group audit, we allocated a materiality that is less than our overall Group materiality. Each component has been assigned materiality individually, with a maximum allocation of £36,000.

Aptamer Group PLC

We set performance materiality at a level lower than materiality to reduce the probability that, in aggregate, uncorrected and undetected misstatements exceed the materiality for the financial statements as a whole. Performance materiality has been set at 75% of overall materiality equal to £117,000. We determined performance materiality with reference to factors such as our understanding of the Group and its complexity, the quality of the control environment and ability to rely on controls and the low level of uncorrected misstatements in the prior year audit.

We agreed with the Audit Committee that we would report to them misstatements identified during our audit above £7,500 (2023: £13.000) being 5% of Group financial materiality as a whole, as well as misstatements below those amounts that, in our view, warranted reporting for qualitative reasons.

# 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

- we identified the laws and regulations applicable to the group through discussions with directors and other management. we focused on specific laws and regulations which we considered may have a direct material effect on the financial statements or the operations of the company, including taxation legislation, data protection, anti-bribery, employment, environmental, health and safety legislation and anti-money laundering regulations.
- we assessed the extent of compliance with the laws and regulations identified above through making enquiries of management and inspecting legal correspondence. identified laws and regulations were communicated within the audit team regularly and the team remained alert to instances of non-compliance throughout the audit; and
- we assessed the susceptibility of the group's financial statements to material misstatement, including obtaining an understanding of how fraud
- making enquiries of management as to where they considered there was susceptibility to fraud, their knowledge of actual, suspected and alleged fraud; considering the internal controls in place to mitigate risks of fraud and non-compliance with laws and regulations.
- To address the risk of fraud through management bias and override of controls, we: performed analytical procedures to identify any unusual or unexpected relationships; tested journal entries to identify unusual transactions; assessed whether judgements and assumptions made in determining the accounting estimates set out in note 3 of the Group
- investigated the rationale behind significant or unusual transactions. In response to the risk of irregularities and non-compliance with laws and regulations, we designed procedures which included, but were not limited to:
- agreeing financial statement disclosures to underlying supporting documentation;
- reading the minutes of meetings of those charged with governance;
- enquiring of management as to actual and potential litigation and claims; reviewing correspondence with HMRC and the group's legal advisors.

periods presented, unless otherwise stated.

The Group has reported a loss after tax for the year ended 30 June 2024 of £3.0 million (year ended 30 June 2023: £7.8 million). The Group had a cash balance of £0.9 million at 30 June 2024 (30 June 2023: £0.2 million).

The Directors have considered the applicability of the going concern basis in the preparation of these financial statements, which includes assessing an internal forecast extending out to June 2026. The Directors consider that this forecast represents a reasonable best estimate of the performance of the Group over the period to June 2026.

In August 2024 the Company completed a fundraise which raised gross proceeds of £2.9 million before expenses. The cash balance at the end of June 2024 was £0.9 million.

We are encouraged by the health of our pipelines, with £0.9 million of revenue visibility so far in the June 2025 financial year and a further £4.3 million of advanced stage sales negotiations.

As a result of Board changes and revisiting some of the operational spend, the fixed cost base has been cut back to circa

In the forecast, full year revenue is anticipated to be higher than was the case in the year to June 2024. Within this forecast, delivery of these expectations would ensure that the resultant positive cashflows together with the current cash balance are

sufficient to see the Group through to June 2026.. The Directors have also considered reasonable likely downside scenarios, which includes slower growth in core revenues. Should these downside scenarios materialise, the Group may need to seek additional funding. The Directors have a reasonable expectation that the Group could access further funding, from both dilutive and non-dilutive sources. However, there can be no quarantee that the Group would be able to raise additional funding from an equity fundraise to new and existing investors, nor that the Group will successfully develop assets for licensing within the next 12 months. Based on the above factors the Directors believe that it remains appropriate to grepare the financial statements on a poing concern basis. However, the above factors give rise to a material uncertainty which may cast doubt over the Group's ability to continue as a going concern and to continue realising its assets and discharging its liabilities in the normal course of business.

Identifiable development expenditure is capitalised to the extent that the technical, commercial

and financial feasibility can be demonstrated. Similarly, any research costs relating to revenue-generating contracts are not capitalised on the grounds that the Group does not retain rights to any intellectual property generated as part of this work. 1.6 Intangible assets

Aptamer Group PLC

The amortisation period and the amortisation method for intangible assets with a finite useful life is reviewed each financial year end. If the expected useful life of the asset is different from previous estimates, the amortisation period is changed accordingly.

The depreciable amount of an intangible asset with a finite life is allocated on a systematic basis over its useful life. Amortisation begins when the asset is available for use.

Subsequent costs are included in the asset's carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured

The assets' residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period.

Gains and losses on disposals are determined by comparing proceeds with carrying amount. These are included in profit or loss. When revalued assets are sold, it is Group policy to transfer any amounts included in other reserves in respect of those assets to

retained earnings.

1.8 Right-of-use assets

A right-of-use asset is recognised at commencement of the lease and initially measured at the amount of the lease liability, plus any incremental costs of obtaining the lease and any lease payments made at or before the leased asset is available for use by the Group. The right-of-use asset is subsequently measured at cost less accumulated depreciation and any accumulated impairment losses. The depreciation methods applied are as follows:

- Right-of use assets

A number of assets have historically been recognised under lease but where there is a final balloon payment which transfers

unconditional ownership into the Group's name. For these assets they have been depreciated over a longer period in accordance with the depreciation policy for the asset class (as shown in 1.7), and on the end date of the lease have been transferred to that

Payments associated with short-term leases of equipment and vehicles and all leases of low-value assets are recognised on a straight-line basis as an expense in grofit or loss. Short-term leases are leases with a lease term of 12 months or less. Low-value

assets comprise IT equipment and small items of office furniture.

The right-of-use asset is subject to impairment testing and adjusted for any remeasurement of the lease liability and lease

modifications. Land and buildings held to earn rental income are classified as investment properties.

Where a right-of-use asset is partially sublet to a third party, but is not separable from the main right-of-use asset, the Group continues to account for this as a right-of-use asset, continuing to depreciate the asset in line across its lease term.

# 1.9 Impairment of tangible and intangible assets

At each reporting end date, the Group reviews the carrying amounts of its tangible and intangible assets on an individual and on a cash-generating unit basis to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if anu). Where it is not possible to estimate the recoverable amount of an individual asset, the Group estimates the recoverable amount of the cash-generating unit to which the asset belongs.

Recoverable amount is the higher of fair value less costs to sell, and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time-value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carruing amount, the carruing amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised immediately in the Statement of Comprehensive Income, unless the relevant asset is carried at a revalued amount in which case

the impairment loss is treated as a revaluation decrease. Recognised impairment losses are reversed if, and only if, the reasons for the impairment loss have ceased to apply. Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised

estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would

1.11 Inventories Raw materials, work in progress and finished goods are stated at the lower of cost and estimated selling price less costs to complete and sell. Cost comprises direct materials, direct labour and an appropriate proportion of variable and fixed overhead expenditure, the latter being allocated on the basis of normal operating capacity. Cost includes the reclassification from equity

of any gains or losses on qualifying cash flow hedges relating to purchases of raw materials but excludes borrowing costs.

Costs are assigned to individual items of inventory on the basis of weighted average costs. Costs of purchased inventory are determined after deducting rebates and discounts. At each reporting date, an assessment is made for impairment. Any excess of the carrying amount of inventories over its

estimated selling price less costs to complete and sell is recognised as an impairment loss in the income statement. Reversals of impairment losses are also recognised in the income statement.

The Group applies a number of key judgements to its impairment calculations, including - Where inventories are used for research projects, these are fully provided for;

Inventories which have been owned for at least 18 months is fully provided for;

Any opened and partially used packages of inventories with a residual value of less than £1,000 are fully provided for; Any other items which are close to or beyond the expiry date are reviewed by laboratory management staff and considered

Cash and cash equivalents are basic financial assets and include cash in hand, deposits held at call with financial institutions and other short-term, highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value.

# provisions of the instrument. Financial assets are classified into specified categories, depending on the nature and purpose of the financial assets. The Group classifies its financial assets in the following measurement categories:

Financial instruments are classified as financial assets measured at amortised cost where the objective is to hold these assets

in order to collect contractual cash flows, and the contractual cash flows are solely payments of principal and interest. They arise principally from the provision of goods and services to customers (e.g. trade receivables). They are initially recognised at

fair value plus transaction costs directly attributable to their acquisition r issue, and are subsequently carried at amortised cost using the effective interest rate method, less provision for impairment where necessary Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal or interest.

Debt instruments Subsequent measurement of debt instruments depends on the Group's business model for managing the asset and the cash flow characteristics of the asset. There are three measurement categories into which the Group classifies its debt instruments: Amortised cost: Assets that are held for collection of contractual cash flows, where those cash flows represent solely

payments of principal and interest, are measured at amortised cost. Interest income from these financial assets is included in finance income using the effective interest rate method. Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other gains/(losses) together with foreign exchange gains and losses. Impairment losses are

losses, interest income and foreign exchange gains and losses, which are recognised in profit or loss. When the financial asset is derecognised, the cumulative gain or loss previously recognised in OCI is reclassified from equity to profit or loss and recognised in other gains/(losses). Interest income from these financial assets is included in finance income using the effective interest rate method. Foreign exchange gains and losses are presented in other gains/(losses), and impairment expenses are presented as a separate line item in the statement of profit or loss. Fair value through grofit or loss (FVPL): Assets that do not meet the criteria for amortised cost or FVOCI are measured at net within other gains/(losses) in the period in which it arises.

1.15 Taxation The income tax expense or credit represents the sum of the tax currently payable or receivable on the current period's taxable income or loss, based on the applicable income tax rate for each jurisdiction, adjusted by changes in deferred tax assets and

**Current** tax

to the tax authorities.

Derecognition of financial liabilities

Equity instruments issued by the Group are recorded at the proceeds received, net of direct issue costs. Dividends payable on

Financial liabilities are derecognised when, and only when, the Group's obligations are discharged, cancelled, or they expire. 1.14 Equity instruments

liabilities attributable to temporary differences and to unused tax losses.

Current tax assets and tax liabilities are offset where the entity has a legally enforceable right to offset and intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

Deferred tax Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are

initial recognition of an asset or liability in a transaction other than a business combination that, at the time of the transaction, affects neither accounting nor taxable grofit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the end of the reporting period and are expected to apply when the related deferred income tax asset is realised or the deferred income tax liability is settled.

Deferred tax assets are recognised only if it is probable that future taxable amounts will be available to utilise those temporary differences and losses.

Deferred tax liabilities and assets are not recognised for temporary differences between the carrying amount and tax bases of

investments in foreign operations where the Company is able to control the timing of the reversal of the temporary differences and it is probable that the differences will not reverse in the foreseeable future.

Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and liabilities and where the deferred tax balances relate to the same taxation authority.

## 1.16 Provisions

Provisions for legal claims, service warranties and make good obligations are recognised when the Group has a legal or

constructive present obligation as a result of a past event, it is probable that the Group will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation. Provisions are not recognised for future operating losses.

Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by

considering the class of obligations as a whole. A provision is recognised even if the likelihood of an outflow with respect to any

one item included in the same class of obligations may be small.

The amount recognised as a provision is the management's best estimate of the consideration required to settle the present obligation at the reporting end date, taking into account the risks and uncertainties surrounding the obligation. The discount rate

used to determine the present value is a pre-tax rate that reflects current market assessments of the time value of money and

the risks specific to the liability. The increase in the provision due to the passage of time is recognised as interest expense. 1.17 Employee benefits

Short-term obligations Liabilities for wages and salaries, including non-monetary benefits, annual leave and accumulating sick leave that are expected

to be settled wholly within 12 months after the end of the period in which the employees render the related service are

recognised in respect of employees' services up to the end of the reporting period and are measured at the amounts expected to

be paid when the liabilities are settled. The liabilities are presented as current employee benefit obligations in the balance sheet. Termination benefits are recognised immediately as an expense when the Group is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

Retirement benefits

The Group operates a defined contribution pension plan. Payments to the defined contribution pension plan are charged as an

expense as they fall due.

Share-based payments

Share-based compensation benefits are provided to employees via the Aptamer Group EMI Share Option Scheme and

unapproved share options. Information relating to these schemes is set out in note 34.

**Employee options** 

The fair value of options granted under the Aptamer Group EMI Share Option Scheme and unapproved share options is

recognised as an employee benefits expense, with a corresponding increase in equity. The total amount to be expensed is determined by reference to the fair value of the options granted:

including any market performance conditions (e.g., the entity's share price);

excluding the impact of any service and non-market performance vesting conditions (e.g., profitability, sales growth targets and remaining an employee of the entity over a specified time period); and including the impact of any non-vesting conditions (e.g., the requirement for employees to save or hold shares for a specific

period of time).

The total expense is recognised over the vesting period, which is the period over which all of the specified vesting conditions are to be satisfied. At the end of each period, the entitu revises its estimates of the number of options that are expected to vest based on the non-market vesting and service conditions. It recognises the impact of the revision to original estimates, if any, in

profit or loss, with a corresponding adjustment to equity.

1.18 Leases On commencement of a contract which gives the Group the right to use an asset for a period of time in exchange for consideration, the Group recognises a right-of-use asset and a lease liability unless the lease qualifies as a 'short-term' lease (term is 12 months or

less with no option to purchase the lease asset) or a 'low-value' lease (where the underlying asset is £4,000 or less when new).

Initial measurement of the lease liability The lease liability is initially measured at the present value of the lease payments during the lease term, discounted using the interest

rate implicit in the lease, or the incremental borrowing rate if the interest rate implicit in the lease cannot be readily determined.

## 1.18 Leases continued

To determine the incremental borrowing rate, the Group:

- where possible, uses recent third-party financing received by the individual lessee as a starting point, adjusted to reflect changes in financing conditions since third-party financing was received;
- uses a build-up approach that starts with a risk-free interest rate adjusted for credit risk for leases held by the Group, which does not have recent third-party financing; and
- makes adjustments specific to the lease, e.g. term, country, currency and security.

The lease is the non-cancellable period of the lease plus extension periods that the Group is reasonably certain to exercise and termination periods that the Group is reasonably certain not to exercise.

Lease payments include fixed payments, less any lease incentives receivable, variable lease payments dependent on an index or a rate, amounts expected to be payable by the Group under residual value guarantees and payments of penalties for terminating the lease, if the lease term reflects the Group exercising that option. Variable lease payments are initially measured using the index or rate when the leased asset is available for use. The cost of the right-of-use asset also includes any provisions expected to be settled on termination of the lease.

## Subsequent measurement of the lease liability

The lease liability is subsequently increased for a constant periodic rate of interest on the remaining balance of the lease liability and reduced for lease payments.

Interest on the lease liability is recognised in the income statement. Variable lease payments not included in the measurement of the lease liability as they are not dependent on an index or rate are recognised in the income statement in the period in which the event or condition that triggers those payments occurs.

When the lease liability is remeasured due to changes arising from the original terms and conditions of the lease, the corresponding adjustment is reflected in the right-of-use asset, or income statement if the right-of-use asset is already reduced to nil.

1.19 Government grants

A lease modification that was not part of the original terms and conditions of the lease is accounted for as a separate lease or an adjustment to the lease liability depending on the nature of the change.

the grant conditions will be met, and the grants will be received.

A grant that specifies performance conditions is recognised in income when the performance conditions are met. Where a grant

Government grants are recognised at the fair value of the asset received or receivable when there is reasonable assurance that

Research and development expenditure credits Where the Group receives research and development expenditure credits ("RDEC") it accounts for these as government grant income within operating income as it more closely aligns with grant income as opposed to a taxation credit. The income is recognised on a systematic basis over the periods in which the entity recognises expenses for the related costs for which the grants are intended to compensate, under IAS 20 'Accounting for Government Grants and Disclosures'.

As well as receiving RDEC, the Group also receives R&D tax credits on the development expenditure it makes on the commercial projects it undertakes. These taxation credits are considered to reflect enhanced tax relief and as such are shown as a reduction in income tax or an increase in receivables due from HM Revenue & Customs 1.20 Foreign exchange

# Transactions and balances

Items included in the financial statements of each of the Group's entities are measured using the currency of the primary economic environment in which the entity operates ('the functional currency"). The consolidated financial statements are presented in Great British Pounds sterling, which is functional and presentation currency of each of the Group's entities.

Functional and presentation currency

Transactions in currencies other than functional currency are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are recognised in the income statement.

Foreign exchange gains and losses that relate to borrowings are presented in the statement of profit or loss, within finance costs. All other foreign exchange gains and losses are presented in the statement of profit or loss on a net basis within other gains/(losses).

Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. Translation differences on assets and liabilities carried at fair value are reported as part of the fair value gain or loss. For example, translation differences on non-monetary assets and liabilities such as equities held at fair value through profit or loss are recognised in profit or loss as part of the fair value gain or loss, and translation differences on non-monetary assets such as equities classified as at fair value through other comprehensive income are recognised in other comprehensive income.

## 1.21 Finance costs

Finance costs are expensed in the period in which they are incurred. Interest paid is included under financing activities in the statement of cash flows.

## 1.22 Earnings per share

Basic Earnings per share is calculated by dividing the profit or loss for the year attributable to the ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the year.

Diluted Earnings per share is calculated by dividing the profit or loss for the year attributable to ordinary equity holders of the parent by the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares. Details of the calculations presented under this are given in note 14.

# 2 Adoption of new and revised standards and changes in accounting policies

In the current year, the following new and revised standards and interpretations have been adopted by the group and have an effect on the current period or a prior period or may have an effect on future periods:

IFRS17 Insurance Contracts: Withdrawal of IFRS4 Insurance Contracts

Amendments to IAS 8: Definition of an accounting estimate

- Amendments to IAS 12 'Income Taxes: Deferred tax relating to assets and liabilities arising from a single transaction
- Amendments to IFRS 10 19 and IAS 28: Sale or contribution of assets between an investor and its associate or joint venture
- Amendments to IAS 1 and IFRS Practice Statement 2: Disclosure of accounting policies
- Standards which are in issue but not yet effective
- Amendments to IAS 12 'Income Taxes': International tax reform Pillar Two Model Rules
- Amendments to IAS 1'Presentation of Financial Statements': Classification of liabilities as current or non-current
- At the date of authorisation of these financial statements, the following standards and interpretations, which have not uet been applied in these financial statements, were in issue but not yet effective (and in some cases had not yet been adopted by the UK Endorsement Board).
- Amendments to IAS 7 and IFRS 7: Supplier finance arrangements
- IFRS SI 'General Requirements for Disclosure of Sustainability-related Financial Information'

Amendments to IAS 1 'Presentation of Financial Statements': Non-current liabilities with covenants

IFRS 19 'Subsidiaries without public accountability': 1 January 2027

 IFRS S2 'Climate-related disclosures': I January 2025 Amendments to IAS 21 to clarify lack of exchangeability: 1 January 2025

— \* IFRS 18 'Presentation and Disclosure in Financial Statements': 1 January 2027

Amendments to IFRS 7 and IFRS 9: Classification and measurement of financial instruments: 1 January 2026.

Effective dates refer to periods commencing on or after this date. The Group's reported financial results are not expected to be materially affected by any standard. However, the presentation and disclosure of its results are expected to be impacted by the adoption of IFRS S1 and IFRS 18 which are both predominantly disclosure-only standards. Given this impacts only disclosures, the Directors do not expect there to be an impact on the reported profits or net assets of the Group from adopting these standards. As these are disclosure-led standards, the Directors have not presented a list of impacts on the financial statements.

For revenues reconised over time, the value of revenue recognised in the period is dependent on an assessment of work to completion.

The Group makes an estimate of the recoverable value of trade and other receivables. When assessing impairment of trade and other receivables, management considers factors including the credit rating of the receivable, the ageing profile of receivables and historical experience. As at 30 June 2024 the provision for trade receivables impairment amounted to £nil (2023: £nil).

Interests in subsidiary undertakings are reviewed annually to assess whether there is objective evidence to indicate that either the carrying value of interests are impaired or impairments recognised in prior periods require to be reversed. Recoverable value of the subsidiary undertaking is estimated as the higher of value-in-use or fair value less cost of disposal. Fair value is based on net assets and incorporates adjustments to reflect the fair market value. See note 19 for the carrying amount of the investments. Management further utilises judgement when assessing the recoverability of intercompany loans using the expected credit loss method in accordance with the requirements of IFRS 9 'Financial Instruments'. Based on these forecasts, all receivables have

The Group assesses these assets, and all other non-monetary assets including property, plant and equipment and right-of-use assets, for impairment on an annual basis by comparing the carrying value of the single cash-generating unit ("CGU") with the recoverable amount, the recoverable amount being based on an assessment of the CGU's value-in-use. The Group uses discounted cashflows from the CGU to determine the value-in-use. The Group sensitises these results and determines if there is

Details of the impairment of property, plant and equipment on a specific basis is provided in note 17. As a result of the ongoing trading conditions of the Group as at the previous year end, combined with the well-publicised risks to viability ahead of the fundraise in August 2023, the Directors reviewed the carrying value of the cash-generating unit ("CGU") in light of the condition. As a result, an impairment was recognised across all non-monetary assets of the Group's single CGU, allocated first to specific intangible assets which are not ongoing, and subsequently pro-rated across the carrying value of all relevant assets. An impairment review has been performed in the current year, detailed in note 16, which has concluded that there is no adjustment (either increased impairment, or reversal of impairment) required as at 30 June 2024. 6 Operating loss

All depreciation, amortisation and impairment are included in administrative expenses.

# 9 Alternative Performance Measures

The Directors have used an Alternative Performance Measure ("APM") in the preparation of these financial statements. The consolidated income statement has presented adjusted earnings before interest, tax, depreciation, and amortisation ("Adjusted EBITDA"), which removes non-cash items including depreciation, amortisation, and share-based payments which are not relevant to the underlying cash generation of the business.

The Directors have presented this APM because they feel it most suitably represents the underlying performance and cash generation of the business, and allows comparability between the current and comparative period in light of the changes in the business, and will allow an ongoing trend analysis of this performance based on current plans for the business.

Development costs capitalised are in relation to the generation of intellectual property and the patenting of such intellectual property, some of which are pending and thus not currently being amortised. As at the year end, £75,000 (2023 - £31,000) of

patents are pending and not yet being amortised.

The Directors prepare forecasts which show the projected growth of the business and use of these assets, which forms a key part of the Group's future strategy. The forecasts include an assessment of the likely commercialisation of the technology based on current demand and anticipated market growth strategies, profiled on a discounted cash flow basis which is further probability weighted for certain sensitivities around key forecasts and the timing of these. This approach is consistent with the review performed in the orevious uear.

As a result of this cashflow forecast, and ongoing trading conditions prevalent at the previous year end, the Directors recognised an impairment at 30 June 2023 as explained in note 5. An impairment review at 30 June 2024 identified no further impairment; this showed that the cashflow forecasts on a cautious basis continue to approximate to the carrying value of the CGU, and were also substantially aligned with the previous year. As a result, no adjustment has been made to the carrying value of the CGU, either in respect of a new impairment or reversing the previous year's impairment charge.

In the prior year, the impairment expense was allocated across all non-monetary assets of the CGU, including property, plant and equipment, and right-of-use assets.

The forecasts used in the previous year were for a specific period of I year, subsequently growing at 25% per annum. In the current year the forecasts include specific growth rates between 0% and 25% annualised, which are factored into the 15 year life on a specific basis. As each project covers a defined term in the event of commercialisation, this has been predicated on a specific basis beyond the 5 year window suggested by IAS 36 on the grounds that this gives a more reliable and risk adjusted expectation than a perpetuity model, and also includes long term growth rates for revenue and costs on a specific basis. More detailed analysis is not provided as to do so may be commercially sensitive.

The key unobservable input to the model was:

A pre-tax discount rate of 32.30% (2023- 34.50%), equating to a post-tax discount rate of 25.30% (2023 - 25.80%).

The main forecasts assumed the going concern status of the Group through anticipated trading following a new fundraising round (as explained in note 39), and its planned use of funds. This fundraise was completed in July and August 2024, which then secured the Group's status as a going concern. As the fundraise successfully completed, management prepared two scenarios addressing successful and unsuccessful completion of the fundraise, which was consistent with the equivalent fundraise and impairment review as at 30 June 2023.

A weighting of 70:30 (2023 – 75:25) in favour of successful completion of the fundraise was applied in calculating the value in use of the CGU. In the current year, as the focus was on projects the successful route was further split into two additional forecasts for timing of these risk-adjusted projects commencing. The forecast for 2024 also reflected the risk to the timing and included a probability weighting of 50% for the original forecast and 50% for an alternative in which all income occurs one year later. If this alternative happens the value in use of the CGU will be reduced to £nil.

The Directors considered sensitivities to revenue and discount rate in the cashflow forecast and the weighting applied between successful and unsuccessful fundraise post period end. If forecasted revenue in the cashflow forecast was reduced by more than 4.8% (2023 - 8%), this would result in a further impairment charge of £734,000 (2023 - £791,000), which would reduce the value in use of the CGU to £nil. If weighting in favour of successful completion of the post period end fundraise was reduced to 52.1:47.9 (2023 - 50:50), this would result in an additional impairment of £734,000 (2023 - £650,000). If the post-tax discount rate was increased by 10% to 35.30% (2023 – 35.80%) then this would result in an additional impairment of £734,000 (2023 - £645,000).

Cashflow projections have been produced for a 15 year period because this is a prudent estimate of the expected product life cycle. No terminal values or perpetuity growth factors have been considered.

The Directors are confident that the value of the CGU as at the date of approval of the financial statements is significantly in excess of the carrying value as at 30 June 2024, as a result of the removal of the uncertainty relating to the 2024 fundraising event. However this value has not been quantified, and cannot be utilised for the purpose of impairment testing as at 30 June 2024 under the requirements of IAS 36.

Further, the Directors are confident that the carrying value of the CGU has the potential to be significantly in excess of that projects are closed positively then the forecasts present an outcome significantly in excess of the carrying value of the CGU.

Notably, volatility is a significant input to the model and is unusually high. The value used is the observable volatility of the Group's share price, as priced on the Alternative Investment Market, from its flotation date to the grant date. Given the recent challenges and changes detailed in note 39, it is expected that similar volatility may be experienced in the short to medium term as the Group continues to grow and commercialise its products. Based on benchmarking of similar quoted companies, other similar companies have a volatility around 60%; if this was used instead then the fair value of the Award would fall from

The Award is expensed over the period in which entitlement to the Award is established through the non-market conditions. This Tranche 1 – total fair value £184,000. Entitlement is determined via revenue targets in the year ended 30 June 2024. These targets

The expense recognised reflects the Directors' best assessment (as at the year end) of the likelihood of achieving revenue conditions in FY25 and FY26, as well as an estimate of the level of staff retention at those dates. Should targets be missed in those years, the amount charged to the P&L this year would be credited back to the P&L, however should targets be met then an

additional charge would need to be recognised in future years in respect of the current year's entitlement. The total expense recognised in the income statement from equity-settled share-based payments is disclosed in note 6.
