SYDNEY, AUSTRALIA, May 11, 2022 (GLOBE NEWSWIRE) -- Iris Energy Limited (NASDAQ: IREN) (“Iris Energy” or “the Company”), a leading sustainable Bitcoin miner which is building an institutional- grade infrastructure platform with 15 EH/s of operating and contracted miners (10 EH/s expected to be operational by early 2023), today reported its financial results for the third quarter ended March 31, 2022. All $ amounts are in United States Dollars (“USD”) and all A$ amounts are in Australian Dollars (“AUD”), unless otherwise stated.

“We remain focused on delivering our strategy of building a global institutional-grade data center platform for our shareholders” stated Daniel Roberts, Co-Chief Executive Officer and Co-Founder of Iris Energy. “We expect the next 12 months will be transformational for the Company.”

Iris Energy’s President, Lindsay Ward, commented, “Over the quarter, the Iris Energy team continued to expand and safely build out our second and third proprietary data center sites in British Columbia, Canada with our fourth site in Texas breaking ground in April. The next 12 months will be an exciting period for the Company as we deliver our hashrate growth targets.”

Third Quarter FY22 Results

Iris Energy generated quarterly revenue of $15.2 million (A$20.2 million) vs. $2.8 million (A$3.7 million) in the prior-year quarter, Adjusted EBITDA of $7.3 million (A$9.8 million) vs. $1.6 million (A$2.1 million) in the prior-year quarter and Adjusted EBITDA Margin of 48% vs. 57% in the prior-year quarter. The increases in revenue and Adjusted EBITDA are largely attributable to the Company’s increased hashrate and Bitcoin mined from the installation of additional capacity at Canal Flats.

Adjusted EBITDA Margin was lower than the prior-year quarter predominantly due to increased corporate costs following the IPO as well as expenses to support the Company’s expansion to 15 EH/s of contracted miners and our development pipeline in excess of 1GW.

IFRS Net Loss After Tax for the quarter was $2.7 million (A$3.6 million), compared to a Net Profit After Tax of $0.5 million (A$0.7 million) in the prior-year quarter, driven predominately by unrealized foreign exchange losses of $5.8 million (A$7.8 million).

Iris Energy generated positive cash flow from operations during the quarter of $4.6 million (A$6.1 million). Iris Energy’s total assets increased 13% in the quarter to $557.3 million (A$743.2 million).

Operational and Corporate Highlights

•

600MW connection agreement signed with AEP Texas at the Company’s Childress site (Texas, USA), increasing the Company’s total announced power capacity to 795MW

•

Expansion to 15 EH/s of installed capacity progressed well across four data center sites:

Canal Flats (BC, Canada) – achieved record average operating hashrate of 833 PH/s (vs. 106 PH/s during the prior-year quarter), exceeding previously announced site capacity of 0.7 EH/s

Mackenzie (BC, Canada) – first 0.3 EH/s (9MW) was commissioned ahead of schedule following quarter end on April 12, with remainder of the first 1.5 EH/s (50MW) still on track for Q3 CY22. Further expansion by 0.9 EH/s (30MW) to a total site capacity of 2.4 EH/s (80MW) is expected to come online in CY23

Prince George (BC, Canada) – first 1.4 EH/s (50MW) remains on track to be energized by the end of Q3 CY22, with foundation works for the first data center building completed ahead of schedule and ongoing site grading, civil works and foundation works progressing for the full 2.4 EH/s (85MW) build out, with the additional 1.0 EH/s (35MW) anticipated to come online in CY23

Childress (Texas, USA) – procurement and early mobilization activities commenced, and purchase orders have been placed on key long-lead items, including the 345kV step-down transformer, 138kV step-down transformers and associated circuit breakers. The first 3.0 EH/s (100MW) of data center buildings are expected to be completed by the end of CY22, with energization targeted for Q1 CY23. The remaining 6.6 EH/s (235MW) of contracted miners are expected to progressively come online until Q3 CY23

In some cases, you can identify forward-looking statements by terminology such as “anticipate,” “believe,” “may,” “can,” “should,” “could,” “might,” “plan,” “possible,” “project,” “strive,” “budget,” “forecast,” “expect,” “intend,” “target”, “will,” “estimate,” “predict,” “potential,” “continue,” “scheduled” or the negatives of these terms or variations of them or similar terminology, but the absence of these words does not mean that statement is not forward-looking. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward looking statements. In addition, any statements or information that refer to expectations, beliefs, plans, projections, objectives, performance or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking.

These forward-looking statements are based on management’s current expectations and beliefs. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause Iris Energy’s actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to: Iris Energy’s limited operating history with operating losses; electricity outage, limitation of electricity supply or increase in electricity costs; long term outage or limitation of the internet connection at Iris Energy’s sites; any critical failure of key electrical or data center equipment; serial defects or underperformance with respect to Iris Energy’s equipment; failure of suppliers to perform under the relevant supply contracts for equipment that has already been procured which may delay Iris Energy’s expansion plans; supply chain and logistics issues for Iris Energy or Iris Energy’s suppliers; cancellation or withdrawal of required operating and other permits and licenses; customary risks in developing greenfield infrastructure projects; Iris Energy’s evolving business model and strategy; Iris Energy’s ability to successfully manage its growth; Iris Energy’s ability to raise additional capital; competition; Bitcoin prices; risks related to health pandemics including those of COVID-19; changes in regulation of digital assets; and other important factors discussed under the caption “Risk Factors” in Iris Energy’s final prospectus filed pursuant to Rule 424(b)(4) with the SEC on November 18, 2021 , as such factors may be updated from time to time in its other filings with the SEC, accessible on the SEC’s website at www.sec.gov and the Investor Relations section of Iris Energy’s website at https://investors.irisenergy.co.

Non-IFRS Financial Measures

This presentation includes non-IFRS financial measures, including Adjusted EBITDA and Adjusted EBITDA Margin. See Financial Summary for a definition of Adjusted EBITDA and Adjusted EBITDA Margin, along with a reconciliation to net profit/(loss) after income tax expense, the nearest applicable IFRS measure, for the periods presented. We provide Adjusted EBITDA and Adjusted EBITDA Margin in addition to, and not as a substitute for, measures of financial performance prepared in accordance with IFRS. There are a number of limitations related to the use of Adjusted EBTIDA and Adjusted EBITDA Margin. For example, other companies, including companies in our industry, may calculate Adjusted EBITDA and Adjusted EBITDA Margin differently. The Company believes that these measures are important and supplement discussions and analysis of its results of operations and enhances an understanding of its operating performance.

All financial information included in this presentation is denominated in USD and references to “$” are to USD unless otherwise stated.

Operating and Financial Overview

The Group uses EBITDA and Adjusted EBITDA as a metric that is useful for assessing its operating performance before the impact of non-cash and other items.

EBITDA is net profit or (loss) from operations, as reported in profit and loss, before finance income and expense, tax and depreciation and amortization.

Adjusted EBITDA is EBITDA adjusted for removing certain non-cash and other items, including share- based payment expenses, foreign currency gains/(losses) and one-time transactions. The below table reconciles (Adjusted) EBITDA to Net Profit/Loss After Tax.

Electricity and other site costs includes electricity charges, site employee benefits, repairs and maintenance and site utilities.

Share-based payments expense includes expenses recorded on Founder options, including (1) Founder price target options (Executive Director Liquidity and Price Target Options) that vested on IPO during the previous quarter ended 31 December 2021. For the 3 months ended 31 March 2022 and onwards no further expense will be recorded in relation to these price target options. (2) Founder long-term options (Executive Director Long-term Target Options) which were granted in September 2021 in connection with the IPO with an expense of US$3.27 million recorded in the three months ended 31 March 2022. These long-term options are currently "out of the money" with an exercise price of US$75 and initial share price vesting conditions of US$370, US$650, US$925 and US$1,850 for each tranche granted. See note 15 of the 31 March 2022 unaudited interim consolidated financial statements for further information.

Share-based payments expense includes expense recorded in relation to incentives issued under the Employee Share Plans, Employee Option Plan and Non-Executive Director Option Plan.

Includes fair value losses recorded on SAFE, convertible notes and associated embedded derivatives that were converted into ordinary shares upon the Group’s listing on the Nasdaq. The net fair value losses recorded on these instruments represents the movement in the share price from date of issuance of these instruments to the IPO listing price of US$28. All of these instruments converted to ordinary shares on 16 November 2021, the associated fair value gains/(losses) are non-cash movements and do not impact the cash position of the Group. See note 5 of the 31 March 2022 interim financial statements for further information.

Industry and Statistical Data This presentation includes industry data, statistical data, estimates and other forecasts that may have been obtained from periodic industry publications, third-party studies and surveys, filings of public companies in our industry, internal company surveys, and our review and analysis of market conditions, surveys and industry feedback.

We undertake no obligation to update such figures in the future. These sources include government and industry sources, including third-party websites. Industry publications and surveys generally state that the information contained therein has been obtained from sources believed to be reliable. Although we believe the industry data to be reliable as of the date of this presentation, this information could prove to be inaccurate. Industry data could be wrong because of the method by which sources obtained their data and because information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process, and other limitations and uncertainties. In addition, we do not know all of the assumptions regarding general economic conditions or growth that were used in preparing the forecasts from the sources relied upon or cited herein. Further, certain financial measures and statistical information in this document have been subject to rounding adjustments. Accordingly, the sum of certain data may not conform to the expressed total. 2

Share-based payments expense includes expenses recorded on Founder options, including (1) Founder price target options (Executive Director Liquidity and Price Target Options) that vested on IPO during the previous quarter ended 31 December 2021. For the 3 months ended 31 March 2022 and onwards no further expense will be recorded in relation to these price target options. (2) Founder long-term options (Executive Director Long-term Target Options) which were granted in September 2021 in connection with the IPO with an expense of US$3.27 million recorded in the three months ended 31 March 2022. These long-term options are currently "out of the money" with an exercise price of US$75 and initial share price vesting conditions of US$370, US$650, US$925 and US$1,850 for each tranche granted. See note 15 of the 31 March 2022 unaudited interim consolidated financial statements for further information. Share-based payments expense includes expense recorded in relation to incentives issued under the Employee Share Plans, Employee Option Plan and Non-Executive Director Option Plan. Includes fair value losses recorded on SAFE, convertible notes and associated embedded derivatives that were converted into ordinary shares upon the Group’s listing on the Nasdaq. The net fair value losses recorded on these instruments represents the movement in the share price from date of issuance of these instruments to the IPO listing price of US$28. All of these instruments converted to ordinary shares on 16 November 2021, the associated fair value gains/(losses) are non-cash movements and do not impact the cash position of the Group. See note 5 of the 31 March 2022 interim financial statements for further information. The Group uses EBITDA and Adjusted EBITDA as a metric that is useful for assessing its operating performance before the impact of non-cash and other items. EBITDA is net profit or (loss) from operations, as reported in profit and loss, before finance income and expense, tax and depreciation and amortization. Adjusted EBITDA is EBITDA adjusted for removing certain non-cash and other items, including share-based payment expenses, foreign currency gains/(losses) and one-time transactions.

Notes to the unaudited interim consolidated financial statements 31 March 2022

Note 1. General information

These unaudited interim consolidated financial statements cover Iris Energy Limited as a Group consisting of Iris Energy Limited ('Company' or 'Parent Entity') and the entities it controlled at the end of, or during, the period (collectively the 'Group'). The unaudited interim consolidated financial statements are presented in Australian dollars ('A$'), which is the Company's functional and presentation currency.

Iris Energy Limited was previously known as Iris Energy Pty Ltd until 7 October 2021, when it converted to an Australian public unlisted company limited by shares. Iris Energy Limited is incorporated and domiciled in Australia. The Group's ordinary shares are listed on the Nasdaq under the trading ticker IREN. Iris Energy Limited's 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 completed an initial public offering ('IPO') on 17 November 2021. The IPO was led by lead book-runners J.P. Morgan, Cannaccord Genuity and Citigroup and raised total gross proceeds of US dollar (‘US$’) 231.5 million. The Group is a Bitcoin mining company that builds, owns and operates data center and electrical infrastructure powered by abundant and/or under-utilized renewable energy.

The unaudited interim consolidated financial statements were authorized for issue, in accordance with a resolution of Directors, on 11 May 2022. The Directors have the power to amend and reissue the unaudited interim consolidated financial statements.

Note 2. Significant accounting policies

These unaudited interim consolidated financial statements for the periods ended 31 March 2022 have been prepared in accordance with IAS 34 Interim Financial Reporting, and should be read in conjunction with the Group’s last annual consolidated financial statements as at and for the year ended 30 June 2021 (‘last annual financial statements’). They do not include all of the information required for a complete set of financial statements prepared in accordance with International Financial Reporting Standards ('IFRS'). However, selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in the Group’s financial position and performance since the last annual financial statements for the year ended 30 June 2021.

The principal accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period, except for the policies stated below.

Reverse share split

On 4 November 2021, the Company effected a 1-for-5 reverse share split of its ordinary shares. Unless otherwise indicated, the per ordinary share information has been retroactively adjusted to reflect the 1-for-5 reverse share split.

New or amended Accounting Standards and Interpretations adopted

The Group has adopted all of the new or amended IFRS and Interpretations as issued by the International Accounting Standards Board ('IASB') 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 unaudited interim consolidated financial statements.

Notes to the unaudited interim consolidated financial statements 31 March 2022

Note 2. Significant accounting policies (continued)

Going concern

The Group has determined there is material uncertainty that may cast doubt on the Group’s ability to continue as a going concern but has concluded it is appropriate to prepare the consolidated interim 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 and securing additional capital.

Since inception of the Company in November 2018, the Group has raised over A$760 million including the recent IPO which raised A$297.5 million, net of underwriting fees.

The ability of the Group to continue as a going concern depends upon the Group maintaining sustained positive free operating cash flows and securing additional capital to fund the contracted mining hardware purchases and infrastructure spend, as part of its growth plan. There are other risks and uncertainties affecting the Group's operations including, but not limited to, the viability of the economics of Bitcoin mining and the ability to execute its business plan.

For the nine months ended 31 March 2022, the Group generated positive operating cashflows of A$19.1 million (31 March 2021: A$2.7 million) and had net current assets of A$197.2 million (30 June 2021: net current liabilities of A$173.5 million) with net assets of A$612.4 million (30 June 2021: net liabilities of A$65.9 million). For the nine months ended 31 March 2022, the Group incurred a loss after tax of A$583.5 million (31 March 2021: A$1.6 million), this loss included a A$540.9 million fair value loss on hybrid instruments which converted to equity on 16 November 2021.

As further background, the Group's miners are 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 significant decline in the market price of Bitcoin, an increase in the difficulty of Bitcoin mining, changes in the regulatory environment and/or adverse changes in other inherent risks would significantly negatively impact the Group’s operations. Due to the volatility of the Bitcoin price and the effects of possible changes in the other aforementioned factors, there can be no guarantee that future mining operations will be profitable.

The strategy to mitigate these risks and uncertainties is to execute a business plan aimed at continued operational efficiency, revenue growth, improving overall mining profit, managing operating and capital expenditure and working capital requirements, and securing additional financing, as needed. The Group is also in a position to wind down its operations (including not acquiring any additional mining hardware and/or incurring the associated infrastructure growth capital expenditure) in the event of unfavourable pricing in Bitcoin. 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 dependent upon a number of factors which have been considered in preparing a cash flow forecast over the next 12 months to consider the going concern of the Group and the ability of the Group to achieve its growth plans. The key assumptions include:

●	the Bitcoin price remaining at a level higher than prior financial years and a lag in global hashrate, thereby contributing to sustained forecast positive free cash flow; and

●

the Group’s contracted mining hardware purchases and infrastructure spend will be funded by a combination of available cash (A$210.7 million as at 31 March 2022), operating cashflow and additional financing (including A$31.4 million financing committed to the Group which as of 31 March 2022 remained undrawn). Of the total contracted mining hardware purchases, US$285.7 million (A$381.9 million) is due to be paid before 31 March 2023, with a further US$90.5 million (A$120.9 million) due beyond 31 March 2023 giving a total contracted mining hardware purchases of US$376.2 million (A$502.8 million) (including estimated shipping and provincial sales tax) as at 31 March 2022.

Note 3. Operating segments

Identification of reportable operating segments

The Group operates within one operating segment, being the operation of building and operating data center sites for the purpose of Bitcoin mining and reports to the Executive Leadership Team, which is made up of the Executive Directors and their Executive Officers (who are identified as the Chief Operating Decision Makers 'CODM') on the performance of the Group as a whole.

Unless stated otherwise, all amounts reported to the Board of Directors are determined in accordance with accounting policies that are consistent with those adopted in these unaudited interim consolidated financial statements. The information reported to the CODM is on a monthly basis.

The CODM uses ‘EBITDA’ and ‘Adjusted EBITDA’ as a metric that is useful for assessing its operating performance before the impact of non-cash and other items.

EBITDA is net profit or (loss) from operations, as reported in profit and loss, before finance income and expense, tax and depreciation and amortization. The accounting policies adopted for internal reporting to the CODM are consistent with those adopted in the unaudited interim consolidated financial statements.

Adjusted EBITDA is EBITDA adjusted for removing certain non-cash and other items, including share-based payment expenses, foreign currency gains/(losses) and one-time transactions.

Note 15. Share-based payments

The Group has entered into a number of share-based compensation arrangements. Details of these arrangements, which are considered as options for accounting purposes, are described below:

Employee Share Plan

The Group's Employee Share Plan is a loan-funded share scheme. These loan-funded shares generally vest subject to satisfying employment service periods (and in some cases, non-market-based performance milestones). The employment service periods are generally met in three equal tranches on the third, fourth and fifth anniversary of the grant date. Under this scheme, the Company issues a limited recourse loan (that has a maximum term of up to 9 years and 11 months) to employees for the sole purpose of acquiring shares in the Company. Upon disposal of any loan-funded shares by employees, the aggregate purchase price for the shares shall be applied by the Company to pay down the outstanding loan payable. 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 IFRS 2 Share-based Payments. Vesting of instruments granted under the Employee Share Plan is dependent on specific service thresholds being met by the employee.

2021 Executive Director Liquidity and Price Target Options

On 20 January 2021, the Group's board approved the grant of 1,000,000 options each to entities controlled by Daniel Roberts and William Roberts (each an Executive Director) to acquire ordinary shares at an exercise price of A$5.0005 with an expiration date of 20 December 2025. All 'Executive Director Liquidity and Price Target Options' vested on completion of the IPO on 17 November 2021 in accordance with the following vesting thresholds:

●	If the liquidity price or volume weighted average market price ('VWAP') of an ordinary share over any consecutive 20 trading day period is equal to or exceeds A$7.00: 300,000 options vest

●	If the liquidity price or VWAP of an ordinary share over any consecutive 20 trading day period is equal to or exceeds A$9.00: 300,000 options vest

●	If the liquidity price or VWAP of an ordinary share over any consecutive 20 trading day period is equal to or exceeds A$11.00: 400,000 options vest

Iris Energy Limited

Notes to the unaudited interim consolidated financial statements 31 March 2022

Note 15. Share-based payments (continued)

The option holder is entitled to receive, in its capacity as a holder of the options, an income distribution per vested option equal to any dividend, distribution, capital return or buyback proceeds (collectively, 'Distribution') paid by the Company per ordinary share as if any vested options were exercised and ordinary shares issued to the option holder at the relevant time of such Distribution. The options are subject to customary adjustments to reflect any reorganization of the Company’s capital. As at 31 March 2022, none of the 2,000,000 outstanding vested 'Executive Director Liquidity and Price Target Options' have been exercised.

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 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. Where an option holder ceases to be a Director of the Company within the vesting period of the options granted, the Board retains the absolute discretion to cancel any unvested options held by the option holder. Vesting of instruments granted under the NED Option Plan is dependent on specific service thresholds being met by the Non-Executive Director.

2021 Executive Director Long-term Target 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 US$75 per option ('Long-term Target Options'). These options were granted on 14 September 2021, and have a contractual exercise period of 12 years.

The Long-term Target Options will vest in four tranches following listing of the Company, if the relevant ordinary share price is equal to or exceeds the corresponding vesting threshold and the relevant executive director has not voluntarily resigned as a director of the Company. The vesting thresholds are detailed below:

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$370: 600,000 Long-term Target Options will vest

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$650: 600,000 Long-term Target Options will vest

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$925: 600,000 Long-term Target Options will vest

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$1,850: 600,000 Long-term Target Options will vest

The VWAP vesting thresholds may also be triggered by a sale or takeover of the Company based upon the price per ordinary share received in such transaction.

The option holder is entitled to receive in its capacity as a holder of the options, a distribution paid by the Company per ordinary share as if the vested options were exercised and ordinary shares issued to the option holder at the relevant time of such distribution.

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.

Valuation methodology

The fair value of instruments issued under the Employee Share Plan, Employee Option Plan and NED Option Plan have been measured using a Black-Scholes-Merton valuation model. The fair value of the Executive Director Liquidity and Price Target Options and 2021 Executive Director Long-term Target Options have been measured using a Monte-Carlo simulation. Service and non-market performance conditions attached to the arrangements were not taken into account when measuring fair value.

The following table list the inputs used in measuring the fair value of arrangements granted during the nine months ended 31 March 2022:

Grant date	Dividend yield	Expected volatility	Risk free interest rate	Expected life (weighted average)	Grant date share price	Exercise Price	Fair value (weighted average)	Number of options granted

Significant Transactions with key management personnel

On or around 18 August 2021, the shareholders of the Company approved the issue of one B Class share each (for consideration of A$1.00 per B Class share) to entities controlled by Daniel Roberts and William Roberts, respectively. The B Class shares were formally issued on 7 October 2021. Each B Class share confers on the holder fifteen votes for each ordinary share in the Company held by the holder. In addition, a B Class share confers a right for the holder to nominate a director to put forward for election to the Board. Because of the increased voting power of the B Class shares, the holders of the B Class shares collectively could continue to control a significant percentage of the combined voting power of the Company's shares and therefore be able to control all matters submitted to the Company’s shareholders for approval until the redemption of the B Class shares by the Company on the earlier of (i) when the holder ceases to be a director due to voluntary retirement; (ii) a transfer of B Class shares in breach of the Constitution; (iii) liquidation or winding up of the Company; or (iv) at any time which is 12 years after the Company’s ordinary shares are first listed on a recognized stock exchange. Aside from these governance rights, the B Class shares do not provide the holder with any economic rights (e.g. the B Class shares do not confer on its holder any right to receive dividends). The B Class shares are not transferable by the holder (except in limited circumstances to affiliates of the holder).
