Disclaimers (Cont'd) Forward-Looking Statements This presentation includes forward-looking statements. These forward-looking statements generally can be identified by the use of words such as "anticipate," "expect," "plan," "could," "may," "will," "believe," "estimate," "forecast," "goal," "project," "potential," "target," "objective," "intend," and other words of similar meaning. These forward-looking statements address various matters including, but not limited to, statements relating to the anticipated benefits, terms, size, and completion of the Proposed Transaction, the expected future market and price of Zcash and other digital assets, the amount of Zcash to be held by Fortitude, Fortitude's upside potential beyond the core Zcash business, the projected financial performance at an illustrative range of Zcash token prices, the illustrative future state of key components of Fortitude Business, including average daily ZEC production, Zcash cash COGS per coin, other cash COGS per coin and, the expected rate of increase of Fortitude's profitability compared to Zcash price movement, the management's strategies and decisions aimed at maximizing return on invested capital, Fortitude's planned acquisitions of mining data centers and expansion of power portfolio expected to reduce cost and provide revenue optionality, HSCS's belief in AI-ECG enabling more effective treatment and earlier diagnosis of heart disease and the timing of 510(k) regulatory approval of MyoVista wavECG. Each forward-looking statement contained in this presentation is subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statement, including among others, the risk that the Proposed Transaction described herein may not be completed in a timely manner or at all; failure to realize the anticipated benefits of the Proposed Transaction; changes in business, market, financial, political and regulatory conditions; and risks relating to our operations and business, and HeartSciences' common stock, including the risk factors described in the Appendix attached hereto and in the section entitled "Risk Factors" of HeartSciences'Annual Report on Form 10-K for the year ended April 30, 2025 filed with the SEC, as may be updated from time to time in HeartSciences' subsequent Quarterly Reports on Form 10-Q, and in other filings that HeartSciences makes with the SEC. We caution investors not to place considerable reliance on the forward-looking statements contained in this presentation. You are encouraged to read HeartSciences' filings with the SEC, available at www.sec.gov, for a discussion of these and other risks and uncertainties. The forward-looking statements in this presentation speak only as of the date of this document, and we undertake no obligation to update or revise any of these statements. Our business is subject to substantial risks and uncertainties, including those referenced above. Investors, potential investors, and others should give careful consideration to these risks and uncertainties. The risk factors described in this presentation, including those relating to digital assets and proof-of-work mining, are not intended to be exhaustive and should be considered in conjunction with, and not as a substitute for, your own independent assessment. The digital asset industry is characterized by rapid technological change, evolving regulatory frameworks, and significant market volatility. Additional risks and uncertainties–such as changes to network protocols (including forks or shifts in consensus mechanisms), increases in mining difficulty or hash rate, disruptions in access to power, cybersecurity threats, and uncertain legal or tax treatment of digital assets–may arise or become material over time and could have a material adverse effect on our business, financial condition, results of operations, or the value of any securities issued in connection with the Proposed Transaction. Past Performance In all cases where historical results are presented or past performance is described, we note that past performance is not a reliable indicator of future results and performance. STRICTLY PRIVATE AND CONFIDENTIAL 3

Disclaimers (Cont'd) Non-GAAP Information This presentation includes information based on financial measures that are not recognized under generally accepted accounting principles in the United States ("GAAP"), such as Fortitude's Adjusted EBITDA and Adjusted General & Administrative Expense. References to "Adjusted EBITDA" mean earnings before interest, taxes, depreciation and amortization, or EBITDA, adjusted for the transaction related expenses and legal non-recurring expenses. Adjusted General & Administrative Expense means General & Administrative Expense, which is further adjusted for the transaction expenses, legal non-recurring expenses and certain other one-time expenses. Such non-GAAP financial measures are presented only as a supplement to Fortitude's financial statements based on GAAP. Non-GAAP financial information is provided to enhance understanding of Fortitude's financial performance, but non-GAAP financial measures are not recognized terms under GAAP, and non-GAAP measures should not be considered in isolation from, or as a substitute analysis for, the company's results of operations as determined in accordance with GAAP. Fortitude uses non-GAAP measures in its operational and financial decision making and believes that such non-GAAP numbers are more representative of the performance of the business and thus instructive for management's strategic planning. Specifically, with respect to each of Adjusted EBITDA and Adjusted General & Administrative Expense, Fortitude believes it is useful to exclude certain items in order to allow for period-over-period comparisons on a more consistent basis and to focus on what it regards to be a more meaningful indicator for evaluating the underlying operating performance of the business. Fortitude also believes that investors may find non-GAAP financial measures useful for the same reasons, although investors are cautioned that non-GAAP financial measures are not a substitute for GAAP disclosures. Net income is the GAAP measure most directly comparable to Adjusted EBITDA. General & Administrative Expense is the GAAP measure most directly comparable to Adjusted General & Administrative Expense. In evaluating both Adjusted EBITDA and Adjusted General & Administrative Expense, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in such presentation. The non-GAAP financial measures are not presented in accordance with GAAP. Please refer to the appendix of this presentation for reconciliations of non-GAAP financial measures contained herein to the most directly comparable GAAP measures. A quantitative reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP measures is not provided because certain reconciling items cannot be reasonably predicted or estimated without unreasonable effort. Please refer to the appendix for further description. Non-GAAP measures are frequently used by securities analysts, investors and other interested parties in their evaluation of companies comparable to Fortitude, many of which present non-GAAP measures when reporting their results. Non-GAAP measures have limitations as an analytical tool. They are not presentations made in accordance with GAAP and are not measures of financial condition or liquidity. Some of these limitations are: (i) both Adjusted EBITDA and Adjusted General & Administrative Expense exclude the transaction-related expenses and non-recurring legal expenses we have incurred, such as litigation costs and one time accounting charges; (ii) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and the cash requirements for such replacements are not reflected in Adjusted EBITDA; (iii) the omission of the amortization expense associated with our intangible assets further limits the usefulness of Adjusted EBITDA; and (iv) Adjusted EBITDA does not include the payment of taxes, which is a necessary element of our operations. Because of these limitations, such non-GAAP measures should not be considered as an alternative to profit or loss for the period determined in accordance with GAAP or operating cash flows determined in accordance with GAAP. Management compensates for these limitations by not viewing the non-GAAP measures in isolation and specifically by using other GAAP measures to measure our operating performance. Fortitude's non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider such performance measures in isolation from, or as a substitute analysis for, the company's results of operations as determined in accordance with GAAP. Preliminary Unaudited Results Included in this presentation are selected preliminary unaudited financial results as of and for the period beginning January 1, 2026 and ended April 30, 2026. These preliminary financial results have been prepared in good faith by the management on a consistent basis with prior periods. However, we have not completed our financial closing procedures for the period ended April 30, 2026 and actual results could be materially different from these preliminary financial results. The Company's independent registered public accounting firm has not conducted an audit or review of and does not express an opinion or any other form of assurance with respect to, the preliminary financial results. During the course our financial closing procedures for the period ended April 30, 2026, we may identify items that would require us to make material adjustments to the preliminary financial results presented herein. As a result, you should not place undue reliance on these preliminary unaudited results and should not draw any inferences from this information regarding financial or operating data not provided. These preliminary financial results should not be viewed as a substitute for full financial statements prepared in accordance with U.S. GAAP. STRICTLY PRIVATE AND CONFIDENTIAL 4

Disclaimers (Cont'd) Projections This presentation contains projected financial information with respect to Fortitude, including an illustrated revenue, gross profit, Adjusted EBITDA, Adjusted General & Administrative Expense, and Adjusted EBITDA margin analysis at various Zcash prices. All such financial projections are forward-looking statements, which are based on assumptions that are inherently uncertain. These projections are presented for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected information are inherently uncertain and are subject to a wide variety of significant business, regulatory, economic and competitive risks and uncertainties. Significant assumptions underlying financial projections included in the presentation include, among others, currently Fortitude operates ~5.2 GSol/s of Zcash miners and expects an additional ~3.3 to 4.7 GSol/s of new miner deliveries throughout the course of 2026; Zcash network hashrate of 24.0 GSol/s by December 2026; weighted average Zcash fleet uptime of 84%, Zcash pool fees of 2%, no Zcash network transaction fees, Zcash cash COGS per coin of $70, annualized Bitcoin mining revenue of ~$27mm based on preliminary, unaudited YTD results through 4/30/2026, and annualized other revenue of ~$1.8mm based on preliminary, unaudited YTD results through 4/30/2026, each of which is subject to assumptions that may prove incorrect. Even if the assumptions underlying financial projections are correct, actual results may be significantly impacted by a variety of factors outside our control, including, but not limited to, the number of machines actually purchased, the ability to successfully deploy the latest generation miners and the ability to achieve lower power costs. All of the projected financial information included in this presentation has been prepared by and is the responsibility of Fortitude's management and has not been audited, reviewed or compiled by an independent registered public accounting firm. Accordingly, there can be no assurance that financial projections are indicative of future performance or that actual results will not differ materially from those presented herein. Inclusion of financial projections in this presentation should not be regarded as a representation by any person that the results contained in the projected information will be achieved. No representation is made regarding the reasonableness or completeness of the assumptions underlying financial projections, modeling or any other information contained in this presentation.

Risk Factors STRICTLY PRIVATE AND CONFIDENTIAL STRICTLY PRIVATE AND CONFIDENTIAL 25

Risk factors (1/4) Risk Factors The following is a summary of the principal factors that make an investment in our securities speculative or risky. As used herein "we", "us" and "our" refers to Fortitude Mining Holdings, Inc. ("Fortitude"), HeartSciences Inc. ("HSCS"), or the proposed combined company as context requires. This summary should not be relied upon as an exhaustive summary of the material risks facing our business, or the potential business combination (the "Proposed Transaction"). Investing in HSCS's securities involves a high degree of risk. Certain factors may have a material adverse effect on our business, financial condition and results of operations and your potential investment in us. Please also refer to the risk factors disclosed in HSCS's filings with the U.S. Securities and Exchange Commission (the "SEC"), including those discussed in the section entitled "Risk Factors" of HSCS's Annual Report on Form 10-K for the year ended April 30, 2025 filed with the SEC, as may be updated from time to time in HSCS's subsequent Quarterly Reports on Form 10-Q, and in other filings that HSCS makes with the SEC. The risks and uncertainties described below (and those in HSCS's SEC filings) are not the only ones that we face. Additional risks that we are unaware of, or that we currently believe are not material, may also become important factors that materially adversely affect us. If any of the risk factors discussed in HSCS's SEC filings or any of the following risks actually occur, our business, financial condition, results of operation, and future prospects could be adversely affected, the trading price of HSCS's common stock could decline, and you could lose all or part of your potential investment. 26 STRICTLY PRIVATE AND CONFIDENTIAL

Risk factors (2/4) Risks Related to Fortitude's Business ▪ We are subject to counterparty risks, including risks and uncertainties relating to our mining site hosting partners. ▪ Our limited rights of legal recourse and lack of insurance over our cryptocurrency holdings expose us to the risk of loss in the event of theft or destruction, for which there may be no adequate remedy. ▪ Cryptocurrency, including Zcash (ZEC) and Bitcoin (BTC), is subject to significant legal, commercial, tax, technical and regulatory uncertainty. ▪ The concentration of our expected digital asset holdings relative to non-digital assets enhances the risks inherent in our digital asset treasury strategy. ▪ A significant decrease in the market value of our digital asset holdings could adversely affect our ability to satisfy financial obligations, including any debt financings. ▪ We may require additional capital to fund our operations and grow our business, which may not be available on acceptable terms, or at all. ▪ If we are unable to raise additional capital on acceptable terms or at all, our ability to implement our business strategy may be compromised. ▪ Financial institutions may discontinue banking services to businesses engaged in crypto-related activities. ▪ We may be unable to timely complete our strategic growth initiatives within our anticipated cost estimates. ▪ We may acquire other assets, form collaborations or make investments in other companies or technologies that could harm our operating results, dilute our stockholders' ownership, or cause us to incur significant expense. ▪ We have engaged in, and may continue to engage in, strategic acquisitions and other transactions that could disrupt our business, dilute our stockholders, increase compliance costs, strain our financial resources and harm our operating results. Our proposed business combination could disrupt our business, increase compliance costs, strain our financial resources and harm our operating results. ▪ Failure to successfully integrate businesses and assets after any strategic transactions could negatively impact our balance sheet and results of operations. ▪ Limited regulation of digital asset exchanges may expose us to negative publicity which could adversely affect an investment in us. ▪ We depend on attracting and retaining officers, managers, and skilled professionals. ▪ Global macroeconomic, geopolitical, and public health events and resulting supply chain issues could adversely affect our business, financial condition, and operations. ▪ We face risks related to technological obsolescence, vulnerability of the global supply chain for cryptocurrency, potential trade restrictions and difficulty in obtaining new hardware, which may have a material adverse effect on our business. ▪ Intellectual property disputes related to digital asset technology could threaten our ability to operate. ▪ If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate to protect our technology and product candidates, our competitive position could be harmed. ▪ We may be exposed to potential liability from claims relating to intellectual property rights. ▪ The adoption and long-term viability of digital asset networks is uncertain, and a decline in their growth or acceptance could negatively impact our business and the value of our stock. ▪ We have derived, and may continue to derive, a substantial portion of our revenues from related parties due to our participation in affiliate Foundry Digital's mining pools, which allow miners to combine their computing and processing power, reducing the variability associated with solving blocks and getting rewarded by the network. ▪ Miner delivery and infrastructure development schedules may be delayed due to constraints in the global supply chains for miners, electricity distribution equipment, and construction materials. 27 STRICTLY PRIVATE AND CONFIDENTIAL

Risk factors (3/4) Risks Related to the Market for Cryptocurrency ▪ There is a finite supply of bitcoin, and the declining block reward over time presents a risk to our business. ▪ Our success depends on external factors affecting the cryptocurrency industry. ▪ Digital asset holdings are less liquid than cash and cash equivalents and may not be able to serve as a source of liquidity for us to the same extent as cash and cash equivalents. ▪ Our ability to generate profit is largely dependent on the price of ZEC and BTC, which has historically been volatile. ▪ Exposure to financially troubled cryptocurrency companies may impact our reputation and operational profitability. ▪ Cryptocurrency faces scaling obstacles, including high transaction fees, which may adversely affect demand for cryptocurrency, our mining operations and growth. ▪ BTC and ZEC are highly volatile digital assets, and fluctuations in the price of BTC and ZEC may adversely influence our financial results and the market price of our listed securities. ▪ Our digital asset holdings expose us to market volatility and liquidity risks, which may affect our ability to effectively manage our growth plans and profitability. ▪ Regulatory, commercial, and technical uncertainties may influence cryptocurrency prices. ▪ Our digital asset management activities expose us to credit, market, liquidity and operational risks. ▪ Geopolitical and economic crises could lead to increased uncertainty, large-scale selloffs of digital assets and a decline in cryptocurrency's value, negatively impacting our business and stock price. ▪ During periods of market stress and extreme volatility, we may be unable to timely liquidate or hedge our cryptocurrency or related positions, and exchange-driven liquidations or auto-deleveraging could materially and adversely affect our liquidity, results of operations and financial condition. ▪ Incorrectly estimating our mining data center lease capacity requirements and capital expenditures could adversely affect our results of operations. ▪ Significant disruptions in the cryptocurrency markets could materially impair the value of our mining rigs, and prolonged low cryptocurrency prices could force us to idle our mining rigs. ▪ Our cryptocurrency miners may not be adaptable to other uses which could adversely affect our business and results of operations. ▪ Noise generated by our mining operations poses regulatory, legal, operational and reputational risks. ▪ Our mining operations may generate less revenue as a result of "halving". ▪ We face risks relating to the potential compromise of the Zcash, Bitcoin and other digital asset network security by emerging technologies, including artificial intelligence and quantum computing. ▪ The cryptography used on the Zcash network could fail or could be used to facilitate illicit activities, and businesses that facilitate transactions in ZEC may be at increased risk of criminal or civil lawsuits. ▪ Our ability to grow our hash rate relative to the global network hash rate and increasing network difficulty may impact our ability to effectively compete. ▪ Disruptions, forks, 51% attacks, hacks, network disruptions, or other adverse events or other compromises to blockchain networks, could materially and adversely impact us. ▪ If a security breach or cyberattack gives unauthorized parties access to our digital assets, or if our access to our wallets holding digital assets is lost or destroyed, we may lose some of, or all of our digital assets. ▪ Loss of access to our private keys or data could result in a permanent loss of our digital assets. ▪ Cyber-attacks, threats, data breaches, or malware may disrupt our operations and expose us to liability, loss of digital assets, reputational damage, and business disruptions which could harm us. ▪ The irreversibility of digital asset transactions exposes us to risks of theft, loss and human error, which could negatively impact our business. ▪ Our revenue generation is subject to risks applicable to mining pools we participate in, including risks outside of our control. ▪ We may not be able to realize the benefits of forks. ▪ We are subject to risks associated with our need for significant electrical power, including risks arising from prolonged power and internet outages, shortages or capacity constraints, which could harm our business. ▪ Certain natural disasters, mechanical failures, cyber incidents, evolving climate and ESG requirements, and other events outside of our control could adversely affect us. 28 STRICTLY PRIVATE AND CONFIDENTIAL

Risk factors (4/4) Risks Related to Governmental Regulation and Enforcement that may affect Fortitude ▪ Changes to laws, regulations, or enforcement priorities may adversely impact our cryptocurrency mining and related activities. ▪ Changes in U.S. trade policy may have a material adverse impact on our business, financial condition and operations. ▪ Our access to power is dependent on third-party providers and regulators and any adverse action by such entity may have a material adverse effect on us. ▪ We may be deemed to be a "commodity pool" under CEA and CFTC Rules as a result of our commodity interest trading. ▪ We are not subject to legal and regulatory obligations that apply to investment companies such as mutual funds and ETPs, or to obligations applicable to investment advisers. ▪ Changes in regulatory interpretations could require us to register as a money services business or money transmitter, leading to increased compliance costs or operational shutdowns. ▪ Regulatory changes may alter the nature of an investment in us or restrict the use of cryptocurrencies in a manner that adversely affects our business. ▪ Absent clearer federal regulations, there is a possibility that ZEC or BTC may be classified as a "security." Any classification of ZEC or BTC as a "security" could lead to our falling under the definition of "investment company" under the Investment Act of 1940, as amended. ▪ Our ZEC treasury strategy may subject us to enhanced regulatory oversight. ▪ We may inadvertently and without knowledge, directly or indirectly, engage in transactions in violation of U.S. or foreign sanctions laws, including as a result of our interactions with a blockchain, which may lead to regulatory penalties and reputational harm. ▪ Compliance costs of responding to new and changing regulations could adversely affect our operations and expose our business to new risks. ▪ Our expanding mining data center ownership may be subject to new or evolving regulatory frameworks. ▪ The rapidly evolving and uncertain regulatory landscape for cryptocurrencies and cryptocurrency mining exposes us to legal risks, compliance costs, and potential business disruptions. ▪ The U.S. political and economic environment could materially impact our business operations and financial performance, and uncertainty surrounding the potential legal, regulatory and policy changes by the U.S. presidential administration may directly affect us and the global economy. ▪ Operating in foreign jurisdictions could expose us to political, legal, and regulatory risks that could negatively impact our financial condition. ▪ Changing environmental, property and tax regulations and public energy policies could increase our costs and adversely affect our business. ▪ The lack of a comprehensive and uniform regulatory framework governing many bitcoin and Zcash trading venues may expose us to market structure risks, fraud, security failures and operational disruptions, which could adversely affect the value and liquidity of our bitcoin holdings. Risks Related to the Proposed Transaction ▪ Failure to complete, or delays in completing, the Proposed Transactions could materially and adversely affect our results of operations, business, financial results and/or HSCS's common stock price. ▪ If the conditions to the Proposed Transactions is not satisfied or waived, the Proposed Transactions may not occur. ▪ The issuance of HSCS's common stock to the stockholder of Fortitude and the resulting change in control must be approved by HSCS's stockholders. Failure to obtain such approval would prevent the closing of the Proposed Transaction. ▪ The Proposed Transactions may be completed even though a material adverse effect may result from the announcement of the Proposed Transactions, industry-wide changes or other causes. ▪ If the Proposed Transaction is not completed, HSCS's stock price may decline significantly. ▪ HSCS's stockholders and the stockholder of Fortitude may not realize a benefit from the Proposed Transactions commensurate with the ownership dilution they will experience in connection with the Proposed Transactions. ▪ The post-Proposed Transactions business of the combined company may not be successful. ▪ The anticipated benefits of the Proposed Transaction may fail to be realized, and the integration of our businesses may be more difficult, costly, or time-consuming than expected. 29 STRICTLY PRIVATE AND CONFIDENTIAL

Reconciliation of Forward-Looking Adjusted EBITDA to Net Income (Loss) A quantitative reconciliation of forward-looking Adjusted EBITDA to forward-looking Net Income (Loss) is not provided because certain reconciling items cannot be reasonably predicted or estimated without unreasonable effort. These items include, but are not limited to: • Impairments of goodwill, intangible assets, long-lived assets, and digital assets, which depend on future market conditions, including the price of Zcash, Bitcoin, and other digital assets; • Mark-to-market gains and losses on digital asset holdings and derivative instruments; • Realized gain/losses on sales or exchanges of digital assets • Stock-based compensation expense tied to future grants, forfeitures, and share price movement; • Transaction-related costs associated with potential acquisitions, divestitures, or capital markets activity; and • Income tax effects of the foregoing items. For similar reasons, the probable significance of such items cannot be reasonably predicted or estimated without unreasonable effort. However, the variability of the items listed above is expected to be significant and could have a material impact on GAAP Net Income (Loss). Accordingly, Fortitude's management is unable to provide a quantitative reconciliation of forward-looking Adjusted EBITDA to forward-looking Net Income (Loss) without unreasonable effort and furthermore does not believe that a GAAP reconciliation would provide meaningful supplemental information about our illustrative guidance. 33 STRICTLY PRIVATE AND CONFIDENTIAL

Calculations Underlying Presentation of Illustrative Financial Performance at Various Zcash Prices • % BTC Market Cap: Calculation reflects the circulating supply of Zcash and Bitcoin as of 4/27/26 and assumes a Bitcoin price of $75,000. • Fortitude Zcash Mined: Calculation reflects daily Zcash production of 430 coins multiplied by 365 days. Average daily Zcash production through 4/30/26 was ~430 Zcash. To maintain production levels, management estimates it will need to procure 4,000 additional Z15 Pro equivalent miners by year end, assuming a year end network hash rate of 24 GS. • Fortitude Zcash Mined Upside: Calculation reflects daily Zcash production of 500 coins multiplied by 365 days. Management estimates it will need to procure 5,500 additional Z15 Pro equivalent miners by year end to achieve this production level. • Zcash Mining Revenue: Calculation reflects Fortitude Zcash Mined multiplied by Zcash Price. • BTC Mining Revenue: Management estimate of $27.0mm relative to preliminary, unaudited YTD BTC Mining Revenue of $9.0mm as of 4/30/26. • Other Revenue: Management estimate of $1.8mm relative to preliminary, unaudited YTD Other Revenue of $0.6mm as of 4/30/26. • Gross Profit: Calculation assumes Zcash Cash COGS per coin of $70 relative to preliminary, unaudited YTD results of $71 per coin as of 4/30/26, Bitcoin gross profit margin of 4.0%, other gross profit margin of 28.3%, management estimated owned site expenses of $2mm per year and $1.7mm of annualized expenses related to Repair Expense, Machine Insurance Expense, and Corporate Insurance Expense. Bitcoin gross profit margin and other gross profit margin in line with preliminary, unaudited YTD actual results as of 4/30/26. At Zcash Cash COGS per coin of $40 rather than $70 per coin, Gross Profit would increase by approximately $5mm. • Adjusted General & Administrative Expense: In line with preliminary, unaudited YTD results of $7.8mm as of 4/30/26 adjusted to remove $2.9mm of non-recurring expenses, comprised primarily of transaction related expenses and non-recurring litigation spend presented on an annualized basis. Annualized number further adjusted to include management's estimate of $5.0mm of public company expenses relative to the annualized figure. • Further Illustrative Adjusted EBITDA: Based on mined quantities described in the Fortitude Zcash Mined Upside line above which assumes 500 Zcash mined per day. Adjusted General & Administrative Expense, Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP metrics. See the discussion of Non-GAAP measures elsewhere in the presentation, as well as elsewhere in this Appendix for a description of why a reconciliation to General & Administrative Expense or Net Income (Loss), the closest GAAP measures, as applicable, is not available for such non-GAAP guidance. 36 STRICTLY PRIVATE AND CONFIDENTIAL The following notes discuss the calculations underlying each metric appearing in the presentation of the Illustrative Financial Performance at Various Zcash Prices provided earlier in this presentation.
