BIOTRON LIMITED

OPERATING AND FINANCIAL REVIEW

Biotron’s core expertise lies in the design and development of drugs that target virus-encoded proteins known as viroporins. Viroporins, which are found in a broad range of viruses and play key roles in viral pathogenesis, are central to viruses modifying host immune responses so that they evade them and maintain ongoing cycles of infection.

Biotron has designed and developed a library of compounds that target viroporins from a broad range of different viruses that cause serious infections in humans and other hosts.

SARS-CoV-2 Program

Biotron has had a long interest in coronaviruses, dating from the SARS-1 epidemic, which provided a good background for knowing how to successfully target SARS-CoV-2 (COVID-19).

BIT225, Biotron’s lead antiviral clinical-stage, investigational, small molecule antiviral drug, has, in addition to its unique clinical activity against HIV-1, shown very good activity against SARS - CoV - 2 and prevented development of disease in a COVID-19 mouse model (ASX announcements 25 November 2021, 17 March 2022 and 2 May 2022).

The SARS - CoV - 2 - infected mice quickly died from respiratory disease very similar to human COVID-19. However, BIT225 very efficiently reduced levels of SARS - CoV - 2 virus and stopped the life - threatening cytokine storm. The mice treated with BIT225 did not develop any signs of disease and remained healthy throughout the several studies that were conducted.

Despite the availability of SARS-CoV-2 vaccines, there remains a need for oral drugs to treat the infection and prevent severe disease, especially in at-risk individuals. BIT225 has an established human safety profile and the potential to be an important first in class drug for the treatment of COVID-19.

In February 2023, the Company presented COVID-19 data from these BIT225 mouse studies at the 30th Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, WA, USA. CROI is the preeminent international HIV research meeting and this year it also featured new findings on SARS-CoV-2 and the mpox virus.

Following the success of the COVID-19 mouse model study, in May 2023 the Company commenced a Phase 2 clinical trial (BIT225-012) at sites in Thailand for the treatment of COVID-19 in humans. The design of this double blind, placebo-controlled trial was based on guidance received during the first half of 2022 from the USA Food and Drug Administration (FDA) and took into consideration the continually changing landscape of COVID-19. The Company consulted with national and international clinicians, clinical research organisations and other relevant experts to design a study that could be recruited quickly and generate meaningful data in a short timeframe.

The trial aims to determine if 7 days of treatment with BIT225 commenced within 3 days of onset of COVID19 symptoms results in reduction in SARS-CoV-2 blood viral load, clinically favourable changes in viral, inflammatory and immune activation markers, as well as improvement in clinical symptoms of COVID-19.

In August 2023, all participants in the BIT225-12 COVID-19 Phase 2 clinical trial completed dosing, marking the end of the clinical phase of the trial. Work is now focused on completing the laboratory analyses of samples collected during the trial.

As with all of its programs, the Company is dedicated to generating high value data to de-risk the portfolio ahead of licensing to a major pharmaceutical company for late-stage development, marketing and sales.

Preliminary results from the BIT225-012 COVID19 trial are expected to be available in September 2023, subject to finalisation of detailed laboratory and other data analyses.

OPERATING AND FINANCIAL REVIEW

HIV-1 Program

During the year in review, the Company completed two Phase 2 clinical trials at sites in Australia and Thailand (BIT225-010 and BIT225-011) for treatment of HIV-1 infection.

The BIT225-011 Australian Phase 2 HIV-1 trial was designed to investigate the impact of BIT225 in HIVinfected people who have been taking approved anti-HIV-1 treatment (ART) for an extended period with wellcontrolled HIV-1 infection but not achieved full immune reconstitution despite long term durably suppressive ART.

This group, estimated to encompass more than one third of the HIV treated population, is at an increased risk of clinical progression to AIDS and other morbidities and has higher rates of mortality than HIV-infected patients who have attained full immune reconstitution.

BIT225 was added to this group’s ART treatment for a period of three months. The endpoints for this trial include measurements of improved immune function and markers linked to immune reconstitution.

The BIT225-010 Thai Phase 2 HIV-1 trial included people newly diagnosed as being HIV-1 positive but not yet commenced ART. They received BIT225 treatment or placebo for six months in combination with ART.

This extended dosing period allows for a more detailed investigation of immune changes observed in previously completed HIV-1 clinical studies with BIT225. The endpoints for this trial include measurements of improved immune function and markers linked to immune reconstitution.

The two trials were designed to generate data to extend the positive findings from previous clinical trials conducted by Biotron in which BIT225 had positive effects on key immunologic markers of improved health outcomes.

Biotron’s anti-HIV-1 drug BIT225 is unique. It is the first drug of its kind to act as both a direct acting antiviral drug and an immune enhancer. Improvements in immune function that appear to be a direct result of BIT225 in the presence of HIV-1 may have additional key health benefits.

The improvements in patients can be assessed by measuring changes in key immune cell populations and markers. Positive changes such as immune function restoration go hand-in-glove with eradication of HIV reservoirs and may be considered surrogate markers of reduction of virus below the level of quantitation.

The data from these two Phase 2 HIV-1 trials will be central to demonstrating to potential pharmaceutical partners and regulatory authorities the safety and efficacy of BIT225 in patients with currently unmet medical needs.

With the clinical phase completed, focus is now on undertaking detailed laboratory analyses of all the samples collected during the trials. The assays are complex, time-consuming, and require specialised external laboratories.

Subject to completion of the laboratory analyses and subsequent data analyses, preliminary results from the HIV-1 trials are anticipated to be available in the third quarter of 2023.

BIOTRON LIMITED

OPERATING AND FINANCIAL REVIEW

Hepatitis B Virus Program

While the clinical programs for HIV-1 and COVID-19 continue to be the Company’s main focus, its HBV program is an important preclinical program.

Like HIV-1, HBV can be treated with drugs that stop the virus replicating, but these do not eradicate the virus.

Chronic infection with HBV can lead to complications such as cirrhosis and liver cancer, which cause close to one million deaths worldwide each year. Over 2 billion people worldwide have been infected with HBV. The World Health Organisation estimates that over 250 million are chronically infected.

Biotron’s compounds have demonstrated significant anti-viral activity against HBV in pre-clinical studies in cellcultures, reducing levels of cccDNA (covalently closed circular DNA), as well as other key viral markers.

Biotron is working with other experienced groups that conduct specific antiviral HBV assays to characterise the mechanism of action of the HBV compounds. In parallel, several unique new compounds are currently being assessed in a series of preliminary preclinical safety studies ahead of their likely assessment in animal models of HBV infection.

The data from these studies further validate the Company’s approach to antiviral drug development.

Commercialisation

The Company’s preclinical and clinical development activities are undertaken with the sole aim of achieving a commercial outcome for its promising antiviral programs.

The COVID-19 pandemic and other infectious disease outbreaks in recent years highlight the importance of novel approaches such as Biotron’s viroporin compounds which have the potential to target a broad range of existing and emerging viruses. Therapeutic drugs such as those in development by Biotron are vital in the fight against pandemics.

Licensing or sale of innovative technology and products by biotechnology companies such as Biotron to major pharmaceutical company partners first requires demonstration of clinical efficacy. The Company has been sharing information on its antiviral programs with potential partners in the pharmaceutical industry since early preclinical development.

Discussions with pharmaceutical companies are iterative in nature. Every successful series of experiments or clinical trial generates another series of questions that will guide the decision-making process on the side of commercial partners. Good, well-founded science is core to success. Feedback from potential partners, as well as advice from experienced international clinical, regulatory and industry advisors has informed every step of development activities undertaken by the Company.

Biotron has generated a compelling package of preclinical and clinical data supported by a robust patent portfolio. The anticipated data from the two Phase 2 HIV-1 clinical trials plus the Phase 2 COVID-19 clinical trial in the second half of 2023 is expected, if positive, to trigger substantive engagement with potential partners. Groundwork has been laid during previous discussions during the development process. The three clinical trials against two indications have been designed to generate data that will clearly demonstrate to the pharmaceutical industry how BIT225 can be best used in the treatment of HIV-1 and COVID-19.

Phase 2 is generally considered the best time to license technology to a major pharmaceutical company as they have the expertise and resources necessary for late stage clinical development and regulatory approvals in major markets such as the USA. This is not a rapid process, nor is there a guarantee of a successful commercial outcome. But we are significantly closer with the end of the three clinical trials in sight.

We appreciate the ongoing support and patience of shareholders while we work to achieve the long awaited commercial outcomes.

BIOTRON LIMITED

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023

1. REPORTING ENTITY

Biotron Limited (the 'Company') is a company domiciled in Australia. The address of the Company’s registered office is at Level 2, 66 Hunter Street, Sydney, NSW 2000. The Company is a for-profit entity and is primarily engaged in the funding and management of intermediate and applied biotechnology research and development projects.

2. BASIS OF PREPARATION

(a) Statement of compliance

These financial statements are general purpose financial statements which have been prepared in accordance with Australian Accounting Standards ('AASBs') adopted by the Australian Accounting Standards Board ('AASB') and the Corporations Act 2001 . The financial statements of the Company also comply with International Financial Reporting Standards ('IFRSs') adopted by the International Accounting Standards Board ('IASB').

The financial report was authorised for issue by the directors on 25 August 2023.

(b) Basis of measurement

The financial statements have been prepared on the historical cost basis, unless otherwise stated.

(c) Functional and presentation currency

These financial statements are presented in Australian dollars, which is the Company’s functional currency.

(d) Use of estimates and judgements

The preparation of financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised and in any future periods affected.

In particular, information about significant areas of estimation uncertainty and critical judgements in applying accounting policies that have the most significant effect on the amounts recognised in the financial statements are described in the following notes:

Note 2 (e) – Going concern

(e) Going concern

The financial statements have been prepared on a going concern basis which contemplates the realisation of assets and settlement of liabilities in the ordinary course of business.

The Company has incurred a trading loss of $3,492,766 for the year ended 30 June 2023 and has accumulated losses of $55,263,766 at 30 June 2023. The Company has cash on hand of $3,984,387 at 30 June 2023 and used $3,290,035 of cash in operations for the year ended 30 June 2023 and received $1,430,725 in research and development government incentives. During the year ended 30 June 2023, the Company raised $6,000,731 before costs for the issue of shares and options. As at 30 June 2023, the Company had net assets of $3,172,656. These conditions give rise to a material uncertainty that may cast significant doubt upon the Company’s ability to continue as a going concern.

The ongoing operation of the Company is dependent on:

the Company raising additional funding from shareholders or other parties; and/or
the Company reducing expenditure in line with available funding.

BIOTRON LIMITED

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023

The directors have prepared cash flow projections that support the ability of the Company to continue as a going concern for the period 1 July 2023 to 31 August 2024. These cash flow projections include significant ongoing expenditure on research and development activities and assume the Company receives the research and development (‘R&D’) rebate from the Australian Government and maintains expenditure in line with available funding.

In the event that the Company does not obtain additional funding and/or reduce expenditure in line with available funding, the achievement of which is significantly uncertain until secured or realised, it may not be able to continue its operations as a going concern and therefore may not be able to realise its assets and extinguish its liabilities in the ordinary course of operations and at the amounts stated in the financial statements.

3. SIGNIFICANT ACCOUNTING POLICIES

(a) Application of accounting policies

The accounting policies set out below have been applied to all periods presented in these financial statements and have been applied consistently by the Company.

(b) New standards and interpretations not yet adopted

A number of new standards, amendments to standards and interpretations are able to be early adopted for annual periods beginning after 1 July 2022 and have not been applied in preparing these financial statements. None of these are expected to have a significant effect on the financial statements of the Company.

(c) Cash and cash equivalents

Cash and cash equivalents comprise cash balances and call deposits with an original maturity of three months or less.

(d) Trade and other receivables

Trade and other receivables are stated at their amortised cost less impairment losses.

(e) Property, plant and equipment

Property plant and equipment are stated at their historical cost less accumulated depreciation and accumulated impairment losses. Depreciation is recognised in profit or loss using the reducing balance method from the date of acquisition at rates between 13% and 40% per annum.

(f) Government grants

Where a grant is received relating to research and development costs that have been expensed, the grant is recognised as other income when the grant becomes receivable and the Company complies with all attached conditions.

Research and development costs

Expenditure on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, is recognised in profit and loss when incurred.

Development activities involve a plan or design for the production of new or substantially improved products and processes. Development expenditure is capitalised only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Company intends to and has sufficient resources to complete development and to use or sell the asset. The expenditure capitalised includes the cost of materials, direct labour and overhead costs that are directly attributable to preparing the asset for its intended use. Otherwise, development expenditure is recognised in profit or loss when incurred.

Capitalised development expenditure is measured at cost less accumulated amortisation and accumulated impairment losses.

BIOTRON LIMITED

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023

(g) Trade and other payables

Trade and other payables are stated at their amortised cost, are non-interest bearing and are normally settled within 60 days.

(h) Employee entitlements

Short-term employee benefits

Short-term employee benefits are expensed as the related service is provided. A liability is recognised for the amount expected to be paid under short term cash bonus or profit sharing plans if the Company has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee, and the obligation can be estimated reliably.

Long term employee benefits

The Company’s net obligation in respect of long term employee benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value. Re-measurements are recognised in profit or loss in the period in which they arise.

Share-based payment transactions

The grant-date fair value of share-based payment awards granted to employees is recognised as an employee expense, with a corresponding increase in equity, over the period that the employees become unconditionally entitled to the awards. The amount recognised as an expense is adjusted to reflect the number of awards for which the related service and non-market vesting conditions are expected to be met, such that the amount ultimately recognised as an expense is based on the number of awards that meet the related service and nonmarket performance conditions at the vesting date. For share-based payment awards with non-vesting conditions, the grant date fair value of the share-based payment is measured to reflect such conditions and there is no true-up for differences between expected and actual outcomes.

(i) Share capital

Ordinary shares

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of ordinary shares are recognised as a deduction from equity, net of any tax effects.

(j) Tax

Income tax comprises of current tax and deferred tax and is recognised in profit or loss except to the extent that it relates to a business combination, or items recognised directly in equity or in other comprehensive income.

Current tax

Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or substantially enacted at the reporting date, and any adjustment to tax payable in respect of previous years. Current tax assets and liabilities are offset only if certain criteria are met.

Deferred tax

Deferred tax is recognised in respect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognised for temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss.

The measurement of deferred tax reflects the tax consequences that would follow the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

BIOTRON LIMITED

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realised simultaneously.

A deferred tax asset is recognised for unused tax losses, tax credits and deductible temporary differences, to the extent that it is probable that future taxable profits will be available against which they can be utilised. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realised.

Goods and services tax

Revenue, expenses and assets are recognised net of the amount of goods and services tax ('GST'), except where the amount of GST incurred is not recoverable from the taxation authority. In these circumstances, the GST is recognised as part of the cost of acquisition of the asset or as part of the expense.

Receivables and payables are stated with the amount of GST included. The net amount of GST recoverable from, or payable to, the ATO is included as a current asset or liability in the balance sheet.

Cash flows are included in the statement of cash flows on a gross basis. The GST components of cash flows arising from investing and financing activities which are recoverable from, or payable to, the ATO are classified as operating cash flows.

(k) Finance income

Finance income comprises interest income on funds invested. Interest income is recognised as it accrues in profit or loss, using the effective interest method.

(l) Earnings per share

The Company presents basic and diluted earnings per share ('EPS') data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Company by the weighted average number of ordinary shares outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding for the effects of all dilutive potential ordinary shares, which comprise share options.

(m) Impairment

Financial instruments

The Company recognises expected credit losses (‘ECLs’), where material, on financial assets measured at amortised cost. The Company measures loss allowances at an amount equal to lifetime ECLs.

Loss allowances are always measured at an amount equal to lifetime ECLs. At each reporting date, the Group assesses whether financial assets carried at amortised cost and debt securities at fair value through other comprehensive income are credit-impaired.

The gross carrying amount of a financial asset is written off when the Group has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof.

(n) Provisions

A provision is recognised if, as a result of a past event, the Company has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects the current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognised as a finance cost.

Determination and presentation of operating segments

The Company determines and presents operating segments based on the information that is provided internally to the Managing Director, who is the Company’s chief operating decision maker.

An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Company’s other components. All operating segments’ operating results are regularly reviewed by the Company’s Managing Director to make decisions about resources to be allocated to the segment and assess its performance.

Segment results that are reported to the Managing Director include items directly attributable to a segment as well as those that can be allocated on a reasonable basis. Unallocated items comprise mainly corporate assets (primarily the Company’s headquarters), head office expenses, and income tax assets and liabilities.

4. DETERMINATION OF FAIR VALUES

A number of the Company’s accounting policies and disclosures require the determination of fair value, for both financial and non-financial assets and liabilities. Fair values have been determined for measurement and/or disclosure purposes based on the following methods. Where applicable, further information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability.

Share-based payment transactions

The fair value of employee share options is measured using the Black-Scholes formula. Measurement inputs include share price on measurement date, exercise price of the instrument, expected volatility (based on weighted average historic volatility adjusted for changes expected due to publicly available information), weighted average expected life of the instruments (based on historical experience and general option holder behaviour), expected dividends, and the risk-free interest rate (based on government bonds). Service and non-market performance conditions attached to the transactions are not taken into account in determining fair value. Share-based payment arrangements in which the Company receives goods or services as consideration for its own equity instruments are accounted for as equity-settled share-based payment transactions.

Non-derivative financial liabilities

Non-derivative financial liabilities are measured at fair value, at initial recognition, and for disclosure purposes, at each annual reporting date. Fair value is calculated based on the present value of future principal and interest cash flows, discounted at the market rate of interest at the measurement date.

7. LOSS PER SHARE

The calculation of basic and diluted loss per share at 30 June 2023 was based on the loss attributable to ordinary shareholders of $3,492,766 (2022 - $2,781,083 loss) and a weighted average number of ordinary shares outstanding during the financial year ended 30 June 2023 of 820,841,956 (2022 – 701,932,713), calculated as follows:

Net loss for the year Weighted average number of ordinary shares (basic and diluted) Issued ordinary shares at 1 July Effect of shares issued (note 15) Weighted average number of ordinary shares at 30 June	3,492,766 2023 Number 701,932,713 118,909,243 820,841,956	2,781,083
		2022 Number 701,932,713 -

As the Company is loss making, none of the potentially dilutive securities are currently dilutive.

The deductible temporary differences and tax losses do not expire under the current tax legislation. Deferred tax assets have not been recognised in respect of these items because it is not probable that future taxable profit will be available against which the Company can utilise the benefits of the deferred tax asset. Deferred tax assets not recognised are calculated at a tax rate of 25% which is the company tax rate that applies from 1 July 2022.

19. FINANCIAL INSTRUMENTS

Financial risk management objectives and policies

The Company’s financial instruments comprise deposits with banks, trade and other payables and from time to time short term loans from related parties. The Company does not trade in derivatives or in foreign currency.

The Company manages its risk exposure of its financial instruments in accordance with the guidance of the Board of Directors. The main risks arising from the Company’s financial instruments are market risk, credit risk and liquidity risks. This note presents information about the Company’s exposure to each of these risks, its objectives, policies and processes for measuring and managing risk, and the Company’s management of capital.

Risk management framework

The Board has overall responsibility for the establishment and oversight of the risk management framework. Informal risk management policies are established to identify and analyse the risks faced by the Company.

The primary responsibility to monitor the financial risks lies with the Managing Director and the Company Secretary under the authority of the Board.

Credit risk

Credit risk arises mainly from the risk of counterparties defaulting on the terms of their agreements.

The carrying amounts of the following assets represent the Company’s maximum exposure to credit risk in relation to financial assets:

Note Cash and cash equivalents 8 Security deposits	Carrying amount 2023 $ 2022 $ 3,984,387 1,741,405 53,930 53,985 4,038,317 1,795,390	Carrying amount 2023 $ 2022 $ 3,984,387 1,741,405 53,930 53,985 4,038,317 1,795,390
		1,795,390

Cash and cash equivalents

The Company mitigates credit risk on cash and cash equivalents by dealing with regulated banks in Australia.

Security deposits

Credit risk on security deposits is very low as it usually consists predominantly of amounts recoverable from a regulated bank in Australia.

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company’s approach to managing liquidity is to ensure, as far as possible, that it will always have sufficient liquidity to meet its liabilities when due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Company’s reputation.

The ultimate responsibility for liquidity management rests with the Board. The Company monitors rolling forecasts of liquidity on the basis of expected fund raisings, trade payables and other obligations for the ongoing operation of the Company. At balance date, the Company has available funds of $3,984,387 for its immediate use.

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and equity prices will affect the Company’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimising the return.

Interest rate risk

The Company’s income statement is affected by changes in interest rates due to the impact of such changes on interest income from cash and cash equivalents and interest bearing security deposits. Changes in interest rates for the current and prior reporting period date would have increased/decreased equity and loss for the period by an immaterial amount.

At balance date, the Company had the following mix of financial assets exposed to variable interest rate risk.

Note Financial assets Cash and cash equivalents 8 Security deposits Net exposure	2023 $ 3,984,387 53,930 4,038,317	2022 $ 1,741,405 53,985

The Company had the following fixed interest bearing financial liabilities in the current year.

Financial liabilities Lease liability 14 Net exposure	45,270 45,270	77,239

In our opinion, the accompanying Financial Report of the Company is in accordance with the Corporations Act 2001 , including:

Material uncertainty related to going concern

We draw attention to Note 2(e), “Going Concern” in the financial report. The conditions disclosed in Note 2(e), indicate a material uncertainty exists that may cast significant doubt on the Company’s ability to continue as a going concern and, therefore, whether it will realise its assets and discharge its liabilities in the normal course of business, and at the amounts stated in the financial report. Our opinion is not modified in respect of this matter.

In concluding there is a material uncertainty related to going concern we evaluated the extent of uncertainty regarding events or conditions casting significant doubt in the Company’s assessment of going concern. This included:

Analysing the cash flow projections by:
Evaluating the underlying data used to generate the projections for consistency with other information tested by us, our understanding of the Company’s intentions, and past results and practices;
Assessing the planned levels of operating and capital expenditures for consistency of relationships and trends to the Company’s historical results since year end, and our understanding of the business, industry and economic conditions of the Company;
Assessing significant non-routine forecast cash inflows and outflows including the expected impact of planned capital raisings for feasibility, quantum and timing. We used our knowledge of the client, its industry and current status of those initiatives to assess the level of associated uncertainty.
Reading minutes of directors’ meetings and relevant correspondence with the Company’s advisors to understand the Company’s ability to raise additional shareholder funds, and assess the level of associated uncertainty.
Evaluating the Company’s going concern disclosures in the financial report by comparing them to our understanding of the matter, the events or conditions incorporated into the cash flow projection assessment, the Company’s plans to address those events or conditions, and accounting standard requirements. We specifically focused on the principle matters giving rise to the material uncertainty.

Key Audit Matters

Key Audit Matters are those matters that, in our professional judgement, were of most significance in our audit of the Financial Report of the current period.

These matters were addressed in the context of our audit of the Financial Report as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

In addition to the matter described in the Material uncertainty related to going concern section, we have determined the matter described below to be the Key Audit Matter.
