Docusign Envelope ID: CA741DAC-AA450-44430-9600億.1F2B9DFE9770億 Iris Energy Limited (d/b/a IREN) Notes to the consolidated financial statements 30 June 2024 13 Note 1. General information The consolidated financial statements cover Iris Energy Limited (d/b/a IREN) as a Group consisting of Iris Energy Limited d/b/a IREN ("Company" or "Parent Entity") and the entities it controlled at the end of, or during, the year (collectively the "Group"). The Company’s shares trade on the NASDAQ under the ticker symbol “IREN”. Iris Energy Limited (d/b/a IREN) is incorporated and domiciled in Australia. Its registered office and principal place of business are: Registered office Principal place of business c/o Pitcher Partners Level 12, 44 Market Street Level 13, 664 Collins Street Sydney NSW 2000 Docklands VIC 3008 Australia Australia The Group is a leading next-generation data center business powering the future of Bitcoin, AI and beyond. The consolidated financial statements were authorized and approved for issue, in accordance with a resolution of Directors, on 28 August 2024. The Directors have the power to amend and reissue the consolidated financial statements. Note 2. Material accounting policies The material accounting policies adopted in the preparation of the consolidated financial statements are set out below. Going concern The Group has determined there is material uncertainty that may cast significant doubt on the Group’s ability to continue as a going concern but has concluded it is appropriate to prepare the consolidated financial statements on a going concern basis which contemplates continuity of normal business activities, the realization of assets and settlement of liabilities in the ordinary course of business. The operating cash flows generated by the Group are inherently linked to several key uncertainties and risks including, but not limited to, volatility associated with the economics of Bitcoin mining and the ability of the Group to execute its business plan. For the year ended 30 June 2024, the Group incurred a loss after tax of $28,955,000 (2023: $171,871,000) and net operating cash inflows of $52,716,000 (2023: $6,045,000). As at 30 June 2024, the Group had net current assets of $401,389,000 (2023: net current assets of $65,229,000) and net assets of $1,097,351,000 (2023: net assets of $305,361,000). As further background, the Group owns mining hardware that is designed specifically to mine Bitcoin and its future success will depend in a large part upon the value of Bitcoin, and any sustained decline in its value could adversely affect the business and results of operations. Specifically, the revenues from Bitcoin mining operations are predominantly based upon two factors: (i) the number of Bitcoin rewards that are successfully mined and (ii) the value of Bitcoin. A decline in the market price of Bitcoin, increases in the difficulty of Bitcoin mining, changes in the regulatory environment, and/or adverse changes in other inherent risks may significantly negatively impact the Group’s operations. Due to the volatility of the Bitcoin price and the effects of the other aforementioned factors, there can be no guarantee that future mining operations will be profitable, or the Group will be able to raise capital to meet growth objectives. The strategy to mitigate these risks and uncertainties is to try to execute a business plan aimed at operational efficiency, revenue growth, improving overall mining profit, managing operating expenses and working capital requirements, Docusign Envelope ID: CA741DAC-AA450-44430-9600億.1F2B9DFE9770億 Iris Energy Limited (d/b/a IREN) Notes to the consolidated financial statements 30 June 2024 Note 2. Material accounting policies (continued) 14 maintaining potential capital expenditure optionality, and securing additional financing, as needed, through one or more debt and/or equity capital raisings. The continuing viability of the Group and its ability to continue as a going concern and meet its debts and commitments as they fall due are therefore significantly dependent upon several factors. These factors have been considered in preparing a cash flow forecast over the next 12 months to consider the going concern of the Group. The key assumptions include: • A base case scenario assuming recent Bitcoin economics including Bitcoin prices and global hashrate; • Three operational sites in British Columbia, Canada with installed nameplate capacity of 160MW; 80MW Mackenzie, 50MW Prince George and 30MW Canal Flats; • A fourth operational site at Childress, Texas with installed nameplate capacity of 100MW as at 31 July 2024 incrementally increasing to 350 MW by 31 December 2024; • Securing additional financing as required to achieve the Group’s growths objectives. The key assumptions have been stress tested using a range of Bitcoin price and global hashrate. The Group aims to maintain a degree of flexibility in both operating and capital expenditure cash flow management where it practicably makes sense, including ongoing internal cash flow monitoring and projection analysis performed to identify potential liquidity risks arising and to try to respond accordingly. As a result, the Group has concluded there is material uncertainty related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern and, therefore, that it may be unable to realize its assets and discharge its liabilities in the normal course of business. However, the Group considers that it will be successful in the above matters and will have adequate cash reserves to enable it to meet its obligations for at least one year from the date of approval of the consolidated financial statements, and, accordingly, has prepared the consolidated financial statements on a going concern basis. Basis of preparation These consolidated financial statements have been prepared in accordance with the Australian Accounting Standards (AASBs) as issued by the Australian Accounting Standards Board (AASB). Historical cost basis The consolidated financial statements have been prepared on a historical cost basis, except for financial assets and liabilities at fair value through profit or loss. Critical accounting estimates The preparation of the consolidated financial statements requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements, are disclosed in note 3. Parent entity information In accordance with the Corporations Act 2001, these financial statements present the results of the consolidated entity only. Supplementary information about the parent entity is disclosed in Note 35. Parent entity disclosures. Rounding off The Company is of a kind referred to in ASIC Corporations (Rounding in Financial/Directors’ Reports) Instrument 2016/191, and in accordance with that Instrument all financial information presented in Australian dollars has been rounded to the nearest thousand unless otherwise stated.

Docusign Envelope ID: CA741DAC-AA450-44430-9600億.1F2B9DFE9770億 Iris Energy Limited (d/b/a IREN) Notes to the consolidated financial statements 30 June 2024 Note 2. Material accounting policies (continued) 15 Principles of consolidation The principles outlined below are guided by AASb 10 ‘Consolidated Financial Statements’ and pertain to the preparation of consolidated financial statements for Iris Energy Limited and its subsidiaries. The consolidated financial statements incorporate the assets and liabilities of all subsidiaries of Iris Energy Limited as at 30 June 2024 and 30 June 2023 and the results of all subsidiaries for the years ended 30 June 2024 and 30 June 2023. Subsidiaries are all those entities over which the Group has control (as listed in note 27). The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases. Where the Group loses control over a subsidiary, it derecognizes the assets including goodwill and liabilities in the subsidiary together with any cumulative translation differences recognized in equity. The Group recognizes the fair value of the consideration received and the fair value of any investment retained together with any gain or loss in profit or loss. Intercompany transactions, balances and unrealized gains on transactions between entities in the Group are eliminated upon consolidation. Accounting policies of subsidiaries align to the policies adopted by the Group. The acquisition of subsidiaries is accounted for using the acquisition method of accounting. A change in ownership interest, without the loss of control, is accounted for as an equity transaction, where the difference between the consideration transferred and the book value of the share of the non-controlling interest acquired is recognized directly in equity attributable to the parent. Operating segments Operating segments are presented using the ‘management approach’, where the information presented is on the same basis as the internal reports provided to the Chief Operating Decision Makers ("CODM"). The CODm is responsible for the allocation of resources to operating segments and assessing their performance. Functional and presentation currency The functional currency of the Parent is Australian dollars, whilst the presentation currency of the Group is in US dollars. Some subsidiaries have a functional currency other than Australian dollars which is translated to the presentation currency. The presentation currency of US dollars has been adopted to suit the needs of the primary users of the financial statements. Transactions in currencies other than an entity’s functional currency are initially recorded in the functional currency by applying the exchange rate ruling at the date of the transaction. Monetary assets and liabilities denominated in currencies other than an entity’s functional currency are retranslated at the foreign exchange rate ruling at the reporting date. Foreign exchange differences arising on translation are recognized in the consolidated statements of profit or loss. Foreign exchange differences that arise on the translation of monetary items that form part of the net investment in a foreign operation are recognized in the foreign currency translation reserve in the consolidated statements of financial position. Non- monetary assets and liabilities that are measured in terms of historical cost in currencies other than an entity’s functional currency are translated using the exchange rate at the date of the initial transaction. Foreign operations The assets and liabilities of foreign operations are translated into US dollars using the relevant exchange rates at the reporting date. The revenues and expenses of foreign operations are translated into US dollars using the average exchange rates, which approximate the rates at the dates of the transactions, for the period. All resulting foreign exchange differences are recognized in other comprehensive income through the foreign currency translation reserve in equity. The foreign currency reserve, reflecting the cumulative translation differences, is recognized in the consolidated statements of profit or loss when the foreign operation or net investment is disposed of. Docusign Envelope ID: CA741DAC-AA450-44430-9600億.1F2B9DFE9770億 Iris Energy Limited (d/b/a IREN) Notes to the consolidated financial statements 30 June 2024 Note 2. Material accounting policies (continued) 16 Revenue and other income recognition The Group recognizes revenue and other income as follows: Revenue from contracts with customers The Group recognizes revenue under AASb 15, “Revenue from Contracts with Customers” ("AASb 15"). The core principle of this standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle: • Step 1: Identify the contract with the customer • Step 2: Identify the performance obligations in the contract • Step 3: Determine the transaction price • Step 4: Allocate the transaction price to the performance obligations in the contract • Step 5: Recognize revenue when the Company satisfies a performance obligation In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets AASb 15’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met: The customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract). If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct. The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity must consider the effects of all of the following: • Variable consideration • Constraining estimates of variable consideration • The existence of a significant financing component in the contract • Non-cash consideration • Consideration payable to a customer Variable consideration is included in the transaction price only to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time or over time as appropriate. Bitcoin mining revenue The Group operates data center infrastructure supporting the verification and validation of Bitcoin blockchain transactions in exchange for Bitcoin, referred to as “Bitcoin mining”. The Group’s revenue is derived from providing computing power (hashrate) to mining pools. The Company has entered into arrangements, as amended from time to time, with mining pool operators to provide computing power to the mining pools. The provision of computing power to mining pools is an output of the Company’s ordinary activities. The Company has the right to decide the point in time and duration for which it will provide computing power. As a result, the Company’s enforceable right to compensation only begins when, and continues as long as, the Company provides computing power to the mining pool. The contracts can be terminated at any time by either party without substantive compensation to the other party for such termination. Upon termination, the mining pool operator (i.e., the customer) is required to pay the Company any amount due related to previously satisfied performance obligations. Therefore, the Company has determined that the duration of the contract is less than 24 hours and that the contract continuously renews throughout the day. The Company has determined that this renewal right is not a material right as the terms, conditions, and compensation amounts are at then market rates.

Docusign Envelope ID: CA741DAC-AA450-44430-9600億.1F2B9DFE9770億 Iris Energy Limited (d/b/a IREN) Notes to the consolidated financial statements 30 June 2024 Note 2. Material accounting policies (continued) 21 In calculating the present value of the lease payments, the Group uses the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group’s incremental borrowing rate. Generally, the Group uses its incremental borrowing rate as the discount rate. The lease liability is subsequently increased by the interest cost on the lease liability and decreased by lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments (e.g. changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset. The Group has applied judgement to determine the lease term for contracts which include renewal and termination options. Goodwill Goodwill arises on the acquisition of a business. Goodwill is not amortized. Instead, the cash-generating unit ("CGU") to which goodwill has been allocated is tested annually for impairment, or more frequently if events or changes in circumstances indicate that it might be impaired and is carried at cost less accumulated impairment losses. Impairment losses on goodwill are taken to profit or loss and are not subsequently reversed. Impairment of other non-financial assets At the end of reporting period, property, plant and equipment and right-of-use assets are reviewed to determine whether there is any indication that those assets have suffered an impairment loss. If there is an indication of possible impairment, the recoverable amount of any affected asset (or group of related assets) is estimated and compared with its carrying amount. An impairment loss is recognized in the profit or loss for the amount by which the asset’s carrying amount exceeds its recoverable amount, where the recoverable amount is the higher of an asset’s fair value less costs of disposal ("FVLCOD") or the value in use ("VIU"). In assessing VIU, the estimated future cash flows of the asset are discounted to their present value using a discount rate that reflects the risks specific to the asset or the CGU to which the asset belongs and relevant market assessments. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash inflows which are largely independent of the cash inflows from other assets or groups of assets. A recognized impairment loss on an asset is subject to reversal if there is a subsequent change in the variables and assumptions that were used to calculate the asset’s recoverable amount. Such a reversal is executed only when the asset’s estimated recoverable amount exceeds its current carrying amount. However, the adjusted carrying amount after reversal must not exceed the asset’s carrying amount that would have been determined (net of depreciation and amortization) had no impairment loss been recognized for the asset in prior years. Trade and other payables These amounts represent liabilities for goods and services provided to the Group prior to the end of the financial year and which are unpaid. They are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method. However, due to their short-term nature, they are not discounted. Financial liabilities Trade and other payables are initially recognized at the fair value of the consideration received, net of transaction costs. They are subsequently measured at amortized cost using the effective interest method. The Group derecognizes financial liabilities when, and only when, the Group’s obligations are discharged, cancelled or they expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in profit or loss. Finance costs Finance costs attributable to qualifying assets are capitalized as part of the asset. All other finance costs are expensed using the effective interest rate method. Provisions Provisions are recognized when the Group has a present (legal or constructive) obligation as a result of a past event, it is probable the Group will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present Docusign Envelope ID: CA741DAC-AA450-44430-9600億.1F2B9DFE9770億 Iris Energy Limited (d/b/a IREN) Notes to the consolidated financial statements 30 June 2024 Note 2. Material accounting policies (continued) 22 obligation at the reporting date, taking into account the risks and uncertainties surrounding the obligation. If the time value of money is material, provisions are discounted using a current pre-tax rate specific to the liability. The increase in the provision resulting from the passage of time is recognized as a finance expense. Employee benefits Short-term employee benefits Liabilities for wages and salaries, including non-monetary benefits, annual leave and long service leave expected to be settled wholly within 12 months of the reporting date are measured at the amounts expected to be paid when the liabilities are settled. Other long-term employee benefits The liability for annual leave and long service leave not expected to be settled within 12 months of the reporting date are measured at the present value of expected future payments to be made in respect of services provided by employees up to the reporting date using the projected unit credit method. Consideration is given to expected future wage and salary levels, experience of employee departures and periods of service. Share-based payments Equity-settled share-based compensation benefits are provided to employees. Equity-settled transactions are awards of shares, or options over shares and restricted stock units ("RSUs"), that are provided to employees in exchange for the rendering of services. The cost of equity-settled transactions is measured at fair value on grant date. Fair value is independently determined using the Black-Scholes-Merton option pricing model and Monte-Carlo simulations which take into account the exercise price, the term of the option or the RSU, the impact of dilution, the share price at grant date, expected price volatility of the underlying share, the expected dividend yield and the risk-free interest rate for the term of the option, together with non- vesting conditions that do not determine whether the Group receives the services that entitle the employees to receive payment. The cost of equity-settled transactions are recognized as an expense with a corresponding increase in equity over the vesting period. The cumulative charge to profit or loss is calculated based on the grant date fair value of the award, the best estimate of the number of awards that are likely to vest and the expired portion of the vesting period. The amount recognized in profit or loss for the period is the cumulative amount calculated at each reporting date less amounts already recognized in previous periods. Market conditions are taken into consideration in determining fair value. Therefore, any awards subject to market conditions are considered to vest irrespective of whether or not that market condition has been met, provided all other conditions are satisfied. If equity-settled awards are modified, as a minimum, an expense is recognized as if the modification has not been made. An additional expense is recognized, over the remaining vesting period, for any modification that increases the total fair value of the share-based compensation benefit as at the date of modification. If equity-settled awards are cancelled or settled during the vesting period (other than a grant cancelled by forfeiture when the vesting conditions are not satisfied), this is treated as an acceleration of vesting and the amount that otherwise would have been recognized for services received over the remainder of the vesting period will be recognized immediately through share- based payments expense in the profit or loss. Fair value measurement When an asset or liability, financial or non-financial, is measured at fair value for recognition or disclosure purposes, the fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; and assumes that the transaction will take place either: in the principal market; or in the absence of a principal market, in the most advantageous market.

Material accounting policies (continued) 23 Fair value is measured using the assumptions that market participants would use when pricing the asset or liability, assuming they act in their economic best interests. For non-financial assets, the fair value measurement is based on its highest and best use, determined by maximization of value by way of continuing use or sale to third party. Valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, are used, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. Assets and liabilities measured at fair value are classified into three levels, using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. Classifications are reviewed at each reporting date and transfers between levels are determined based on a reassessment of the lowest level of input that is significant to the fair value measurement. Transfers between levels of the fair value hierarchy are recognized at the end of the reporting period in which they occur. For recurring and non-recurring fair value measurements, external valuers may be used when internal expertise is either not available or when the valuation is deemed to be significant. External valuers are selected based on market knowledge and reputation. Where there is a significant change in fair value of an asset or liability from one period to another, an analysis is undertaken, which includes a verification of the major inputs applied in the latest valuation and a comparison, where applicable, with external sources of data. Issued capital Ordinary shares are classified as equity because they represent ownership in the company and do not have an obligation to be repurchased or settled in cash or other financial assets. Incremental costs directly attributable to the issue of new shares are shown in equity as a deduction, net of tax, from the proceeds. Earnings per share Basic earnings per share Basic earnings per share is calculated by dividing the profit attributable to the owners of Iris Energy Limited (d/b/a IREN), by the weighted average number of ordinary shares outstanding during the financial year. The weighted average number of shares is also adjusted for any ordinary shares to be issued under mandatorily convertible instruments issued by the Group. Diluted earnings per share Diluted earnings per share adjusts the figures used in the determination of basic earnings per share to take into account the after income tax effect of interest and other financing costs associated with dilutive potential ordinary shares and the weighted average number of shares assumed to have been issued for no consideration in relation to dilutive potential ordinary shares. Foreign currency translation reserve The reserve is used to recognize exchange differences arising from the translation of the financial statements of foreign operations to United States dollar. Share-based payments reserve The reserve is used to recognize the value of equity benefits provided to employees and Directors as part of their remuneration, and other parties as part of their compensation for services. Goods and Services Tax ("GST") and other similar taxes Revenues, expenses and assets are recognized net of the amount of associated GSt, unless the GSt incurred is not recoverable from the tax authority. In this case it is recognized as part of the cost of the acquisition of the asset or as part of the expense. Receivables and payables are stated inclusive of the amount of GSt receivable or payable. The net amount of GSt recoverable from, or payable to, the tax authority is included in other receivables or other payables in the consolidated statements of financial position. Cash flows are presented on a gross basis. The GSt components of cash flows arising from investing or financing activities which are recoverable from, or payable to the tax authority, are presented as operating cash flows. Docusign Envelope ID: CA741DAC-AA450-44430-9600億.1F2B9DFE9770億 Iris Energy Limited (d/b/a IREN) Notes to the consolidated financial statements 30 June 2024 Note 2. Material accounting policies (continued) 24 Commitments and contingencies are disclosed net of the amount of GSt recoverable from, or payable to, the tax authority. Computer hardware prepayments Computer hardware prepayments represent payments made by the Group for the purchase of mining and HPC hardware that were yet to be delivered as of the end of the financial year. These prepayments are in accordance with payment schedules set out in relevant purchase agreements with hardware manufacturers. Government grants Grants from the government are recognized at their fair value where there is a reasonable assurance that the grant will be received and the Group expects to comply with the conditions. Depending on the grant conditions, grants received may be deferred and recognized over time on a straight-line basis. Rounding of amounts Amounts in this report have been rounded off to the nearest thousand dollars, or in certain cases, the nearest dollar. New or amended Accounting Standards and Interpretations adopted The Group has adopted all of the new or amended AASBs and Interpretations as issued by the AASb that are mandatory for the current reporting period. Any new or amended Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. The Group believes that the impact of recently issued standards or amendments to existing standards that are not yet effective will not have a material impact on the Group’s consolidated financial statements. Note 3. Critical accounting judgements, estimates and assumptions The preparation of the consolidated financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts in the consolidated financial statements. Management continually evaluates its judgements and estimates in relation to assets, liabilities, contingent liabilities, revenue and expenses. Management bases its judgements, estimates and assumptions on historical experience and on other various factors, including expectations of future events, management believes to be reasonable under the circumstances. The resulting accounting judgements and estimates will seldom equal the related actual results. The judgements, estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities (refer to the respective notes) within the next financial year are discussed below. Share-based payment transactions The Group measures the cost of equity-settled transactions with employees by reference to the fair value of the equity instruments at the date at which they are granted. The fair value is determined by using the Black-Scholes-Merton option- pricing model and Monte-Carlo simulations which take into account the terms and conditions upon which the instruments were granted. Management has exercised its best judgements in determining the key inputs for the valuation models used which includes volatility, grant-date share price, expected term and the risk-free rate. Refer note 31 for further information and key assumptions. Estimation of useful lives of assets The Group determines the estimated useful lives, residual values and related depreciation charges for its property, plant and equipment. The useful lives could change significantly as a result of technical innovations or some other event. The depreciation charge will increase where the useful lives are less than previously estimated lives, or technically obsolete or non-strategic assets that have been abandoned or sold will be written off or written down. Impairment of non-financial assets The Group assesses impairment of non-financial assets other than goodwill at each reporting date by evaluating conditions specific to the Group and to the particular asset that may lead to impairment. If an impairment trigger exists, the recoverable amount of the asset is determined. This involves assessing the value of the asset at FVLCOD or using VIU models which incorporate a number of key estimates and assumptions.

Share-based payments (continued) 51 The recourse on the loan is limited to the lower of the initial amount of the loan granted to the employee and the proceeds from the sale of the underlying shares. Employees are entitled to exercise the voting and dividend rights attached to the shares from the date of allocation. If the employee leaves the Company within the vesting period, the shares may be bought back by the Company at the original issue price and the loan is repaid. Loan-funded shares have been treated as options as required under AASb 2 Share-based Payments.

All ‘Executive Director Liquidity and Price Target Options’ vested on completion of the IPO on 17 November 2021. Employee Option Plan The Board approved an Employee Option Plan on 28 July 2021. The terms of the Employee Option Plan are substantially similar to the Employee Share Plan, with the main difference being that the incentives are issued in the form of options and loans are not provided to participants. If the employee leaves the Company within the vesting period of the options granted, the Board retains the absolute discretion to cancel any unvested options held by the employee. Vesting of options granted under the Employee Option Plan is generally dependent on specific service thresholds being met by the employee. Non-Executive Director Option Plan The Board approved a Non-Executive Director Option Plan ("NED Option Plan") on 28 July 2021. The terms of the NED Option Plan are substantially similar to the Employee Option Plan. Vesting of instruments granted under the NED Option Plan is dependent on specific service thresholds being met by the Non-Executive Director. Where an option holder ceases to be a Director of the Company within the vesting period, the options granted to that Director will vest on a pro-rata basis of the associated service period. The Board retains the absolute discretion to cancel any remaining unvested options held by the option holder. $75 Exercise Price Options On 18 August 2021, the Group’s shareholders approved the grant of 2,400,000 long-term options each to entities controlled by Daniel Roberts and William Roberts to acquire ordinary shares at an exercise price of $75 per option ("$75 Exercise Price Options"). These options were granted on 14 September 2021, and have a contractual exercise period of 12 years. The options are subject to customary adjustments to reflect any reorganization of the Company’s capital, as well as adjustments to vesting thresholds including any future issuance of ordinary shares by the Company.
