This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements relate to our future plans, objectives, expectations and intentions and may be identified by terminology such as “may,” “will,” “should,” “expects,” “aims,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “intends,” or “continue,” or the negative of these terms or other comparable terminology. Readers are cautioned that these forward-looking statements are based on our current beliefs, expectations and assumptions and are subject to risks, uncertainties, and assumptions that are difficult to predict, including those identified below, under Part II, Item 1A “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q and those risks identified under Part I, Item 1A of our Annual Report on Form 10-K for the year ended April 30, 2023 filed with the Securities and Exchange Commission on July 19, 2023 ("2023 Annual Report on Form 10-K"). Therefore, actual results may differ materially and adversely from those expressed, projected or implied in any forward-looking statements. We undertake no obligation to revise or update any forward-looking statements for any reason.

These forward-looking statements may include, but are not limited to, statements relating to our objectives, plans and strategies, statements that contain projections of results of operations or of financial condition, expected capital needs and expenses, statements relating to the research, development, completion and use of our device, and all statements (other than statements of historical facts) that address activities, events or developments that we intend, expect, project, believe or anticipate will or may occur in the future.

Forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties. We have based these forward-looking statements on assumptions and assessments made by our management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate.

Important factors that could cause actual results, developments and business decisions to differ materially from those anticipated in these forward-looking statements include, among other things:

•our expectation regarding the sufficiency of our existing cash and cash equivalents to fund our current operations;

•our ability to receive regulatory clearance for our planned products including the MyoVista wavECG, (the “MyoVista”), other AI-ECG algorithms which we have licensed from the Icahn School of Medicine at Mount Sinai (“Mount Sinai AI-ECG Algorithms") and related cloud-based delivery platform (“Cloud Platform”), from the U.S. Food and Drug Administration, (the “FDA”), state regulators, if any, or other similar foreign regulatory agencies, including approval to conduct clinical trials, the timing and scope of those trials and the prospects for regulatory approval or clearance of, or other regulatory action with respect to the MyoVista or other future potential products;

•our ability to advance the development of the MyoVista, our 12-lead electrocardiograph, (“ECG”), device that incorporates an additional proprietary artificial intelligence (“AI”)-based algorithm that has been designed to detect cardiac dysfunction and the Mount Sinai AI-ECG Algorithms and Cloud Platform which we intend to develop to provide AI-ECG algorithms on a hardware agnostic basis;

•our ability to launch sales of the MyoVista and the Mount Sinai AI-ECG Algorithms and Cloud Platform into the U.S.;

•our assessment of the potential of the MyoVista, the Mount Sinai AI-ECG Algorithms and Cloud Platform;

•our planned level of capital expenditures and liquidity;

•our plans to continue to invest in research and development to develop technology for new products;

•the regulatory environment and changes in the health policies and regimes in the countries in which we intend to operate, including the impact of any changes in regulation and legislation that could affect the medical device industry;

•our ability to meet our expectations regarding the commercial supply of the MyoVista, the Mount Sinai Ai-ECG Algorithms, and Cloud Platform;

•our ability to retain key executives;

•our ability to internally develop new inventions and intellectual property;

•the overall global economic environment;

•the ultimate impact of the COVID-19 pandemic, or any other health epidemic, on our business, our clinical trials, our research programs, healthcare system or the global economy as a whole;

•the impact of competition and new technologies;

3

•general market, political and economic conditions in the countries in which we operate;

•our ability to develop new products and intellectual property;

•changes in our strategy; and

•potential litigation.

These statements are only current predictions and are subject to known and unknown risks, uncertainties, and other factors that may cause our or our industry’s actual results, levels of activity, performance or achievements to be materially different from those anticipated by the forward-looking statements.

Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Except as required by law, we are under no duty to update or revise any of the forward-looking statements, whether as a result of new information, future events or otherwise for any reason.

The Company will continue to file annual, quarterly and current reports, proxy statements and other information with the Securities and Exchange Commission (the “SEC”). Forward-looking statements speak only as of the dates specified in such filings. Except as expressly required under federal securities laws and the rules and regulations of the SEC, we do not undertake any obligation to update any forward-looking statements to reflect events or circumstances arising after any such date, whether as a result of new information or future events or otherwise. You should not place undue reliance on the forward-looking statements included in this report or that may be made elsewhere from time to time by us, or on our behalf. All forward-looking statements attributable to us are expressly qualified by these cautionary statements.

Notes to Condensed Unaudited Financial Statements

Note 1. Basis of Presentation

Heart Test Laboratories, Inc. d/b/a HeartSciences (“HeartSciences” or the “Company”) is a medical technology company specializing in cardiovascular diagnostic technology. The Company is a Texas corporation and is headquartered in Southlake, Texas.

HeartSciences’ initial focus is on applying novel technology to extend the clinical indications for use of an electrocardiograph (“ECG”) device. HeartSciences’ first product candidate, the MyoVista, is a resting 12-lead ECG that will incorporate HeartSciences’ first AI-based algorithm that is being developed for use in a wide range of clinical settings and is designed to provide diagnostic information to a qualified healthcare professional on cardiac dysfunction which has traditionally only been provided using cardiac imaging. In addition, the MyoVista provides conventional ECG information. The Company plans to market its device, both domestically and internationally to various hospitals, clinics, and medical centers and manufacture the devices using outsourced production facilities. Additionally, the Company plans to deliver AI-based algorithms either through the MyoVista hardware or through a cloud-based platform to provide access to a range of AI-based ECG cardiovascular algorithms on an ECG hardware agnostic basis. To date the Company has had small amounts of revenue from key opinion leader engagement and establishment of distributor relationships outside the United States during the development and product improvement phase of the MyoVista. The Company is preparing to seek U.S. Food and Drug Administration (“FDA”) clearance of the MyoVista during the first half of calendar year 2024.

Note 2. Liquidity, Going Concern and Other Uncertainties

The Company is subject to a number of risks similar to those of early-stage companies, including dependence on key individuals and products, the difficulties inherent in the development of a commercial market, the need to obtain additional capital, competition from larger companies, and other technologies.

The Company has incurred losses each year since inception and has experienced negative cash flows from operations in each year since inception. At October 31, 2023 and April 30, 2023, the Company had an accumulated deficit of $63.9 million and $60.8 million, respectively. These factors raise substantial doubt regarding the Company's ability to continue as a going concern.

In March 2023, the Company entered into a purchase agreement and a registration rights agreement with an institutional investor, providing for the sale, from time to time at the discretion of the Company, of up to $15.0 million of the Company’s Common Stock, over the thirty-six (36) month term of the purchase agreement (the “Equity Line”). As of October 31, 2023, the Company has issued and sold an aggregate 1,277,689 shares of Common Stock, including 100,000 commitment shares, under the Equity Line and received proceeds of approximately $1.0 million (see Note 5). Subsequent to October 31, 2023 and through the date of this filing, the Company sold 586,833 shares of Common Stock under the Equity Line, receiving proceeds of approximately $91,000.

In September 2023, the Company entered into a Senior Unsecured Promissory Drawdown Loan Note (“MSW Note”) for up to $1.0 million, drawn in installments consisting of (i) $0.25 million on or prior to September 8, 2023, (ii) ) $0.25 million on or prior to September 20, 2023, and (iii) further drawdowns of up to $0.5 million in such amounts and such times to be mutually agreed upon between the Company and lender. As of October 31, 2023, the Company has drawn $0.5 million under the MSW Note. See Note 5 and Note 9 for further discussion.

In September 2023, the Company entered into an Equity Distribution Agreement (“EDA”) with an institutional investor, pursuant to which the Company may offer and sell an aggregate of up to $3.25 million of its shares of Common Stock in at-the-market offerings (“ATM Facility”). In November 2023, the EDA was further amended increasing the aggregate amount of Common Stock that may be sold under the ATM Facility from $3.25 million to up to $15.0 million. The Company is eligible to sell up to approximately $11.0 million worth of shares of Common Stock as the aggregate market value of the Company's shares of Common Stock eligible for sale under the EDA is subject to limitations of General Instruction I.B.6 of Form S-3 until such time that the Company's public float equals or exceeds $75.0 million. In the event the aggregate market value of the Company’s outstanding Common Stock held by non-affiliates equals or exceeds $75.0 million, then the one-third limitation on sales set forth in General Instruction I.B.6 of Form S-3 shall not apply to additional sales made pursuant to the EDA. As of October 31, 2023, the Company has issued and sold an aggregate 184,699 shares of Common Stock and received net proceeds of approximately $55,000 (see Note 5). Subsequent to October 31, 2023 and through the date of this filing, the Company sold 40,175,218 shares of Common Stock under the ATM Facility, receiving net proceeds of approximately $9.2 million (see Note 9).

Based on the Company’s forecasts and cashflow projections, management believes that current resources would be insufficient to fund operations to achieve commercialization. Additionally, the FDA can delay, limit or deny clearance of a medical device for many reasons outside the Company’s control which may involve substantial unforeseen costs.

The Company's continued operations will depend on its ability to raise additional capital through various potential sources, such as equity and/or debt financings and strategic relationships. The Company expects no material commercial revenue in Fiscal 2024. Management can provide no assurance that such financing or strategic relationships will be available on acceptable terms, or at all, which would likely have a material adverse effect on the Company and its financial statements.

The condensed unaudited financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern for a reasonable period. See subsequent equity raises discussed in Note 9.

Note 3. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) and in conformity with the instructions on Form 10-Q and Rule 8-03 of Regulation S-X and the related rules and regulations of the Securities and Exchange Commissions (“SEC”) and have been prepared on a basis which assumes that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. In the opinion of management, the unaudited interim financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results of operations for the periods presented. The interim operating results are not necessarily indicative of results that may be expected for any subsequent period. The accompanying unaudited condensed financial statements should be read in conjunction with the Company's audited financial statements and notes thereto included in the 2023 Annual Report on Form 10-K.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The fair value of cash and cash equivalents approximates carrying value. At times, the Company’s cash balances may exceed the current insured amounts under the Federal Deposit Insurance Corporation (“FDIC”).

Inventory

All inventories are stated at lower of cost or net realizable value, with cost determined substantially on a “first-in, first-out” basis. Selling, general, and administrative expenses are not inventoried, but are charged to expense when incurred. The following is a summary of the Company’s inventories at October 31, 2023 and April 30, 2023:

	October 31,			April 30,
	2023			2023
Raw materials	$	322,996		$	322,996
Sub-assemblies		345,916			347,436
Work in progress		21,741			21,741
Finished goods		28,662			28,662
Reserve for obsolescence		(44,476	)		(44,476	)
Total Inventory	$	674,839		$	676,359

Inventory consists mainly of raw materials and components used in the current hardware build of the MyoVista. Devices and components are used for research and development purposes and device sales, which to date have been in international markets as sale of the MyoVista in the U.S. is subject to FDA clearance. The Company is partway through a new pivotal clinical validation study and device testing necessary for a revised FDA submission, which is targeted to take place during the first half of calendar year 2024. The Company believes that its hardware platform is in final form, however, prior to FDA clearance and market acceptance of the

7

8

MyoVista, further hardware changes could be necessary which could have an impact on net realizable values. The majority of the Company’s current inventory is intended for use to build finished products following regulatory clearance. Finished products do not contain materials that would degrade significantly over the useable life of the device and are considered to have a useable life of over seven years. Existing inventory related to finished devices are planned to be updated to the latest hardware revision and specifically allocated to a limited distribution for field reliability studies and are not slated for general purpose sales. The Company periodically evaluates inventory and makes specific write-offs and provides an allowance for inventory that is considered obsolete due to hardware and or software related changes. If the Company does not receive FDA clearance and/or obtain market acceptance of the MyoVista, the Company could have further material write-downs of inventory due to obsolescence in excess of the amount currently reserved.

Research and Development Expenses

In accordance with ASC Topic 730, Accounting for Research and Development Costs, the Company accounts for research and development expenditures, including payments to collaborative research partners and regulatory filing costs, as research and development expenses. Accordingly, all research and development costs are charged to expense as incurred.

Property and Equipment

Property and equipment are recorded at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives. The range of estimated useful lives used to calculate depreciation is generally 3 to 5 years. Ordinary maintenance and repairs are charged to expense as incurred, and replacements and betterments are capitalized. When items are retired or otherwise disposed, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in other income (expense).

The following is a summary of the Company’s property and equipment at October 31, 2023 and April 30, 2023:

	October 31,			April 30,
	2023			2023
Equipment	$	404,782		$	397,920
Furniture & fixtures		102,563			102,563
Leasehold improvements		32,812			32,812
Total		540,157			533,295
Less: Accumulated depreciation		(486,841	)		(471,867	)
Property and equipment, net	$	53,316		$	61,428

Deferred Offering Costs

The Company capitalizes certain legal, professional, and other-third party charges, related to capital raises through a sale of Common Stock in its IPO or other ongoing equity financings, as deferred offering costs until fully consummated. On October 16, 2023, the Company filed an S-1/A registration statement which has not yet been declared effective by the SEC. These costs are deferred until the completion of the offerings at which time they are reclassified to additional paid-in-capital as a reduction of the offering proceeds. If the Company terminates the planned offering or there is a significant delay, all of the deferred offering costs will be immediately written off to operating expenses.

On March 10, 2023, the Company entered into the Equity Line. Deferred offering costs associated with the Equity Line are reclassified to additional paid in capital on a pro-rata basis over the term of the agreement.

In September 2023, the Company entered into an EDA to sell its Common Stock under the ATM Facility. Deferred offering costs associated with the ATM Facility are reclassified to additional paid in capital on a pro-rata basis.

As of October 31, 2023 and April 30, 2023, $624,171 and $175,921 of deferred offering costs were capitalized on the balance sheet, respectively.

Fair Value Measurements

The accounting guidance establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset transaction between market participants on the measurement date. Where available, fair value is based on observable market prices or

8

9

is derived from such prices. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

•Level 1 – Observable inputs such as quoted prices in active markets;

•Level 2 – Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly;

•Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the assignment of an asset or liability within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The carrying amounts of the Company’s financial instruments, which primarily include cash and cash equivalents, accounts payable and accrued expenses, approximate their fair values due to their short-term nature. The carrying amounts of the Company’s existing notes payable approximate their fair values at the stated interest rates and are reflective of the prevailing market rates.

Leases

The Company determines if a contract is or contains a lease at inception or modification of a contract. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period in exchange for consideration. Control over the use of the identified asset means the lessee has both (a) the right to obtain substantially all of the economic benefits from the use of the asset and (b) the right to direct the use of the asset. Right-of-use assets and liabilities are recognized based on the present value of future minimum lease payments over the expected lease term at commencement date. The Company measures and records a right-of-use asset and lease liability based on the discount rate implicit in the lease, if known. In cases where the discount rate implicit in the lease is not known, the Company measures the right-of-use assets and lease liabilities using a discount rate equal to the Company’s estimated incremental borrowing rate for loans with similar collateral and duration.

The Company elected to not apply the recognition requirements to leases of all classes of underlying assets that, at the commencement date, have a lease term of 12 months or less and do not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise. Instead, lease payments for such short-term leases are recognized in operations on a straight-line basis over the lease term and variable lease payments in the period in which the obligation for those payments is incurred.

Stock-Based Compensation

The Company accounts for employee and non-employee share-based compensation in accordance with the provisions of ASC 718, Compensation – Stock Compensation. Under ASC 718, share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the requisite service period (generally the vesting period of the equity grant).

The estimated fair value of Common Stock option awards is calculated using the Black-Scholes option pricing model, based on key assumptions such as fair value of Common Stock, expected volatility, and expected term. These estimates require the input of subjective assumptions, including (i) the expected stock price volatility, (ii) the calculation of the expected term of the award, (iii) the risk-free rate and (iv) expected dividend yields. As there has not been a historic public market for the Company’s Common Stock, management has determined the expected stock price volatility at the time of grant of the option by considering a number of objective and subjective factors, including stock price volatility of comparable companies that are publicly available and based on the industry, stage of life cycle, size and financial leverage of such other comparable companies.

Management has estimated the expected term of its Common Stock options using the “simplified” method, whereby, the expected term equals the arithmetic average of the vesting term and the original contractual term of the option due to its lack of sufficient historical data. The risk-free interest rates for periods within the expected term of the option are based on the US Treasury securities with a maturity date that commensurate with the expected term of the associated award. There is no expected dividend yield since the Company has never paid cash dividends and does not expect to pay cash dividends in the foreseeable future.

9

10

For stock options issued to employees and non-employees, the fair value of stock-based awards is recognized as compensation expense over the requisite service period, which is defined as the period during which an employee is required to provide service in exchange for an award. The Company uses a straight-line attribution method for all grants that include only a service condition. The Company accounts for forfeitures when they occur. Stock-based compensation expense recognized in the financial statements is reduced by actual awards forfeited.

Net Loss Per Common Share

Basic net loss per share excludes the effect of dilution and is computed by dividing the net loss attributable to common shareholders by the weighted-average number of shares of Common Stock outstanding during the period, without consideration of potentially dilutive securities.

Diluted net loss per share is computed by dividing the net loss attributable to common shareholders by the weighted-average number of Common Stock and potentially dilutive securities outstanding for the period. For purposes of the diluted net loss per share calculation, convertible preferred stock, stock options, Common Stock subject to repurchase related to early exercise of stock options, convertible stock warrants and convertible notes are considered to be potentially dilutive securities. As the Company has reported a net loss for all periods presented, diluted net loss per common share is the same as basic net loss per common share for those periods.

Common Stock Warrants

When the Company issues warrants to purchase Common Stock in connection with financing transactions, the warrants are valued based on Black-Scholes models and the fair value is recorded to additional paid-in-capital.

Revenue Recognition

In accordance with ASC 606, Revenue from Contracts with Customers, revenue is recognized when a customer obtains control of promised goods or services. The guidance focuses on the core principle for revenue recognition, which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company recognizes revenue in accordance with ASC 606, which provides a five-step model for recognizing revenue from contracts with customers as follows:

•Step 1: Identify the contract(s) with a 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 (or as) the entity satisfies a performance obligation

A contract with a customer exists when (i) the Company enters into a legally enforceable contract with a customer, through a purchase order, that defines each party’s rights regarding the products to be transferred and identifies the payment terms related to these products, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for products that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The only performance obligation is to create and ship the product and each product has separate, distinct pricing. Performance obligations are met and revenue is recognized at a point in time when the order for its goods are shipped FOB manufacturer and control is transferred.

The transaction price is determined based on the amount expected to be entitled to in exchange for transferring the product to the customer net of any transaction price adjustments. The Company’s payment terms to customers generally range from 30 to 60 days.

Payment terms fall within the one-year guidance for the practical expedient which allows the Company to forgo adjustment of the promised amount of consideration for the effects of a significant financing component. The Company accepts product returns at its discretion or if the product is defective as manufactured. Historically, the actual product returns have been immaterial to the Company’s financial statements. The Company elected to treat shipping and handling costs as a fulfillment cost and included them in the cost of goods sold as incurred. Costs associated with product sales include commissions. The Company applies the practical expedient and recognizes commissions as expense when incurred because the expense is incurred at a point in time and the amortization period is less than one year. Commissions are recorded as selling expense.

10

11

The Company did not recognize material revenues during the three and six month periods ended October 31, 2023 and 2022. The Company’s revenues do not require significant estimates or judgments. The Company is not a party to contracts that include multiple performance obligations or material variable consideration. As of October 31, 2023 and April 30, 2022, the Company did not have any contract assets or liabilities from contracts with customers and there were no remaining performance obligations that the Company had not satisfied.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires recognition of deferred tax assets, subject to valuation allowances, and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes. Management considers many factors when assessing the likelihood of future realization of deferred tax assets, including recent cumulative experience by taxing jurisdiction, expectations of future taxable income or loss, the carry-forward periods available to the Company for tax reporting purposes, and other relevant factors.

A valuation allowance is established if it is more likely than not that all or a portion of the net deferred tax assets will not be realized.

Accruals for uncertain tax positions are provided for in accordance with applicable accounting standards. The Company may recognize the tax benefits from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Judgement is required in assessing the future tax consequences of events that have been recognized in the financial statements or tax returns.

Based on its analysis, management has determined that it has not incurred any liability for unrecognized tax benefits as of October 31, 2023 and April 30, 2022.

The Company may be subject to potential examination by U.S. federal, U.S. states or foreign jurisdiction authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with U.S. federal, U.S. state and foreign tax laws.

The Company is subject to income taxes in the U.S. federal jurisdiction and franchise taxes in the State of Texas. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. Generally, the Company is no longer subject to income tax examinations by major taxing authorities for years before 2018.

$1M Notes and Loan and Security Agreement

In April 2020, the Company entered into a loan and security agreement (the “$1M Loan and Security Agreement”) pursuant to which a secured promissory note in the original principal amount of $500,000 was issued to each of FRV (the “FRV Note”) and John Q. Adams (the “JQA Note”), who are both shareholders of the Company. John Q. Adams was also a Director of the Company at the time of entering into the $1M Loan and Security Agreement. Each party committed to lend a principal amount of $500,000, totaling $1,000,000, and the loan was drawn in three installments of $300,000 upon execution of the loan agreement, $350,000 on or about July 2, 2020 and $350,000 on or about September 4, 2020. The loan had an original maturity date of September 30, 2021, which was amended on September 30, 2021 making the note repayable on demand.

11

12

The $1M Loan and Security Agreement was amended again on November 3, 2021, extending the maturity to September 30, 2022. The loan was further amended on May 24, 2022, extending maturity to September 30, 2023. In connection with the amendment in May 2022, the Company agreed to pay Mr. Adams all accrued but unpaid interest on his note prior to September 30, 2022. In June 2022, the Company paid approximately $126,000 in accrued interest to Mr. Adams.

The $1M Loan and Security Agreement was further amended on January 24, 2023 to (i) extend the maturity date of the FRV Note to September 30, 2024, on which date the principal amount and all accrued interest thereon will be due and payable, and (ii) amend the dates on which principal and accrued interest is due under the JQA Note, such that interest accrued since June 28, 2022 will be due and payable on September 30, 2023, and the principal amount together with all accrued interest after September 30, 2023 will be due and payable on March 31, 2024.

The $1M Loan and Security Agreement was further amended on September 29, 2023 to amend the dates on which principal and accrued interest is due under the JQA Note, such that interest accrued since June 28, 2022 will be due and payable on December 31, 2023, and the principal amount together with all accrued interest after December 31, 2023 will be due and payable on March 31, 2024. As consideration for an extension of the JQA interest maturity date, in October 2023, the Company issued warrants to purchase an aggregate of 200,000 shares of Common Stock to FRV and Mr. Adams (“$1M Lender Warrants”). See further discussion in Note 5.

In November 2023, the principal amount of the JQA Note and accrued interest thereon in the amount of $585,006 converted into Common Stock of the Company. See further discussion in Note 9.

The $1M Loan and Security Agreement accrues interest at a rate of 12% per annum, compounded annually, which is payable as described above. The Company is also required to pay default interest at a rate of 18% per annum, compounded annually, on any unpaid amounts after the applicable due date until the loan amounts are fully re-paid. The loan is collateralized by substantially all of the Company’s assets and intellectual property, except for the secured interest on the covered technology as discussed in Note 8.

As of October 31, 2023 and April 30, 2023, accrued interest was approximately $310,000 and $238,000, respectively, and is included in accrued expenses in the accompanying condensed balance sheets.

MSW Note

On September 6, 2023, the Company entered into the MSW Note with Matthews Holdings Southwest, Inc., (the “Lender”). The MSW Note provides for an unsecured drawdown loan of up to $1.0 million, drawn in installments consisting of (i) $250,000 on or prior to September 8, 2023, (ii) $250,000 on or prior to September 20, 2023, and (iii) further drawdowns of up to $500,000 in such amounts and such times to be mutually agreed upon between the Company and Lender. In consideration of the MSW Note, the Company shall pay a facility fee to the Lender as follows:

•warrants to acquire 500,000 shares of Common Stock, exercisable at $1.00 per share, which shall be issued to the Lender upon the completion of the first drawdown;

•warrants to acquire up to 500,000 shares of Common Stock, exercisable at $1.25 per share, of which 250,000 of such warrants shall be issued to the Lender upon the completion of the first drawdown and 250,000 of such warrants shall be issued to the Lender pro-rata based on further drawdowns up to $500,000; and

•warrants to acquire up to 500,000 shares of Common Stock, exercisable at $1.50 per share, of which 250,000 of such warrants shall be issued to the Lender upon the completion of the first drawdown and 250,000 of such warrants to be issued to the Lender pro-rata based on further drawdowns up to $500,000.

The MSW Note bears no interest, except upon an event of default, at which time, interest accrues at a rate of 12% per annum. The MSW Note matures on December 31, 2023 and may be repaid at any time in whole or in part without fees or penalty.

In September 2023, the Company drew $0.5 million under the MSW Note and issued warrants in lieu of a facility fee to purchase 500,000 shares of Common Stock exercisable at $1.00 per share, warrants to purchase 250,000 shares of Common Stock exercisable at $1.25 per share, and warrants to purchase 250,000 shares of Common Stock exercisable at $1.50 per share. The Company recorded a $165,751 debt discount relating to the warrants issued based on the relative fair value of the warrants on the date of issuance. The debt discount is being amortized over the life of the note as a non-cash interest expense. As of October 31, 2023, amortization recorded was approximately $83,000.

In November 2023, the MSW Note converted into Common Stock of the Company. See further discussion in Note 9.

Note 5. Stockholders’ (Deficit) Equity

Preferred Stock

The Company authorized 20,000,000 shares of preferred stock, par value $0.001 per share (“Preferred Stock”), of which 10,000 shares have been designated as Series A Convertible Preferred Stock (“Series A Preferred Stock”), 10,000 shares have been designated as Series B Convertible Preferred Stock (“Series B Preferred Stock”), and 600,000 shares have been designated as Series C Preferred Stock with a liquidation preference to Common Stock.

Series C Preferred Stock

The Series C Preferred Stock was originally issued at $25.00 per share. An amendment to, or waiver of rights in, the Series C Preferred Stock certificate of designation requires the approval of holders of a majority of the outstanding shares of Series C Preferred Stock and FRV (so long as FRV owns at least 71,000 shares of Series C Preferred Stock).

At October 31, 2023 and April 30, 2023, there were 380,440 and 380,871 shares of Series C Preferred Stock outstanding, respectively.

Holders of the Series C Preferred Stock are entitled to receive dividends at an annual rate of $1.50 per share of Series C Preferred Stock, shall accrue and are payable out of funds legally available, are payable only when and if declared by the board of directors, and are noncumulative. No dividends have been declared to date. The holders of the shares of Series C Preferred Stock have voting rights equal to an equivalent number of shares of Common Stock into which it is convertible and vote together as one class with Common Stock.

Each share of Series C Preferred Stock is convertible, at the option of the holder at any time, into such number of fully paid and non-assessable shares of Common Stock determined by dividing the original issue price of $25.00 by the conversion price for such series in effect at the time of conversion for the Series C Preferred Stock. The conversion price for the Series C Preferred Stock is subject to adjustment in accordance with conversion provisions contained in the Company's certificate of formation, as amended.

During the six months ended October 31, 2023, 431 shares of Series C Preferred Stock converted into 1,938 shares of Common Stock at a conversion ratio of 4.4981 shares of Common Stock for each share of Series C Preferred Stock. At October 31, 2023, the Series C Preferred Stock were convertible into 1,888,641 shares of Common Stock at a conversion price of $5.04 per share.

At December 14, 2023, the Series C Preferred Stock were convertible into 6,366,520 shares of Common Stock at a conversion price of $1.49 per share.

Common Stock

The Company’s Certificate of Formation, as amended, authorizes 500,000,000 shares of Common Stock with a par value of $0.001 per share. As of October 31, 2023 and April 30, 2022, the Company had issued 11,213,438 and 10,118,440 shares of Common Stock, respectively.

During the six months ended October 31, 2023, the Company issued 1,094,998 shares of Common Stock, as set forth in the below table:

	Number of Shares
Issuance of Common Stock under Equity Line		799,665

The shares may be issued and sold from time to time through or to the placement agent acting as sales agent or principal pursuant to our shelf registration statement on Form S-3 (the “Shelf S-3”), as filed with the SEC on September 18, 2023. The $3.25 million shares comprised of Common Stock that may be offered, issued and sold under the at-the-market offering prospectus is included in the $50.0 million of securities that may be offered, issued, and sold by the Company under the base prospectus of the Shelf S-3. The Shelf S-3 was declared effective by the SEC on September 28, 2023. During the six months ended October 31, 2023, the Company issued 184,699 shares of Common Stock under the ATM Facility, receiving approximately $55,000 in net proceeds. See further discussion at Note 9.

During the six months ended October 31, 2023, the Company issued 108,696 shares of Common Stock as consideration for consulting services.

The holders of Common Stock are entitled to receive dividends whenever funds and assets are legally available and when declared by the board of directors, subject to the rights of holders of Preferred Stock outstanding. No dividends were declared as of or through the six months ended October 31, 2023 and the year ended April 30, 2023.

Common Stock Warrants

The Company has issued warrants to investors in connection with funding or for services rendered and these warrants are convertible into a number of shares of the Company’s Common Stock for a period of 5 years from the date of issuance.

The following is a summary of warrant activity during the six months ended October 31, 2023:

	Warrants Outstanding and Exercisable			Exercise Price Per Share	Weighted Average Strike Price per Share
Balance, April 30, 2023		2,590,342		$0.0001-$15.18	$	3.73

Balance, October 31, 2023		3,791,321		$0.0001-$9.90	$	2.87

In September 2023, the Company issued warrants in lieu of a facility fee under the MSW Note to purchase 500,000 shares of Common Stock exercisable at $1.00 per share, warrants to purchase 250,000 shares of Common Stock exercisable at $1.25 per share, and warrants to purchase 250,000 shares of Common Stock exercisable at $1.50 per share.

In September 2023, the Company issued warrants to purchase up to 15,000 shares of Common Stock, at an exercise price of $0.73 per share, to a consultant of the Company as consideration for services rendered to the Company.

In October 2023, the Company issued $1M Lender Warrants to FRV and John Q. Adams to purchase an aggregate of 200,000 shares of Common Stock at an exercise price of $0.44.

Note 6. Stock-based Compensation

The Company grants certain employees and board members stock option awards where vesting is contingent upon a service period, as it believes that such awards better align the interests of its employees with those of its shareholders. Stock option awards are granted with an exercise price equal to or above the market price of the Company’s stock at the date of grant. Certain stock option awards provide for accelerated vesting if there is a change in control, as defined in the Nonstatutory Stock Option Agreement. Unvested stock options forfeit when an employee leaves the Company.

14

15

Time-based grants generally vest quarterly based on 3 years continuous service for executive directors and employees, or 12 months continuous service for directors and have 10-year contractual terms. The Company also grants stock option awards where vesting is contingent upon meeting various departmental and company-wide performance goals, including FDA and CE Mark regulatory approval and certain EBITDA and funding thresholds. Such performance-based stock options are expected to vest when the performance criteria and metrics have been met. These stock options have contractual lives of ten years.

2023 Equity Incentive Plan

On March 15, 2023, the Company's Board of Directors adopted the 2023 Equity Incentive Plan (the “Equity Incentive Plan”), subject to shareholder approval. The Equity Incentive Plan provides for the grant of nonstatutory stock options, incentive stock options, restricted stock, restricted stock units, performance units, performance shares, and other share-based awards. Pursuant to the Equity Incentive Plan, the Company is authorized to issue up to 2,500,000 shares of Common Stock plus (i) any shares of our Common Stock subject to options that expire or otherwise terminate without having been exercised in full, are tendered to or withheld by us for payment of an exercise price or for tax withholding obligations, or are forfeited to or repurchased by us due to failure to vest, with the maximum number of shares of our Common Stock to be added to the Equity Incentive Plan under this clause (ii) equal to 832,195 shares of our Common Stock.

The following is a summary of service-based stock option activity during the six months ended October 31, 2023:

	Number of Options Outstanding			Weighted Average Exercise Price		Average Remaining Contractual Life (in years)
Outstanding - April 30, 2023		1,182,912		$	3.29		8.6
Options forfeited		(114,545	)		3.04		—

Vested at October 31, 2023		188,952		$	2.67		6.8

As of October 31, 2023, there was approximately $0.3 million of unrecognized compensation costs related to non-vested service-based Common Stock options and approximately $1.6 million of unrecognized compensation costs related to non-vested performance-based Common Stock options.

Note 7. Income Taxes

The tax effects of temporary differences and carry-forwards that give rise to significant portions of the deferred tax assets and liabilities are presented below:

	October 31,			April 30,
	2023			2023
Deferred tax assets (liabilities):
Net operating loss carryforwards	$	10,561,200		$	9,701,650
Start-up costs		884,458			934,999
Stock option and warrant payments		662,095			538,669

Total deferred tax assets, net		12,381,616			11,449,295
Valuation Allowance		(12,381,616	)		(11,449,295	)
Net Deferred Tax Assets	$	—		$	—

For the six months ended October 31, 2023 and the year ended April 30, 2023, the Company’s cumulative net operating loss for federal income tax purposes was approximately $50 million and $46 million, respectively. The net operating loss, subject to limitations, may be available in future tax years to offset taxable income. The net operating loss carry-forward will begin to expire in year 2028.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based upon the projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will not realize the benefits of these deductible differences, and therefore, a full valuation allowance has been recorded at October 31, 2023 and April 30, 2023.

Note 8. Commitments and Contingencies

Operating Leases

The Company has a long-term operating lease for office, industrial, and laboratory space which was entered into in May 2017. On September 27, 2022, the Company entered into the First Amendment to Lease (the “Lease Amendment”), which amended the Lease Agreement to document the exercise of its option to extend the term of the lease for an additional 64 months, commencing February 1, 2023, and expiring on May 31, 2028 (the “Extension Term”). Pursuant to the amendment, the Company will pay initial monthly payments of $13,129, beginning February 2023, subject to 3% annual increases. Rent expense for the six months ended October 31, 2023 was approximately $74,000.

The Company records right-of-use assets and liabilities at the present value of the fixed lease payments over the term at the commencement date. The Company uses its incremental borrowing rate of 12% to determine the present value of the lease as the rate implicit in the lease is typically not readily available.

Information related to the Company’s right-of-use assets and lease liabilities consist of the following:

	October 31,
	2023
Right-of-use assets	$	502,831
Lease liabilities, current	$	94,463
Lease liabilities, net of current portion		486,885
Total lease liabilities	$	581,348
Weighted average remaining term (in years)		4.6
Weighted average discount rate		12	%

17

As of October 31, 2023, future maturities of lease liabilities due under lease agreements for the fiscal year ended are as follows:

2024 (balance of fiscal year)	$	78,778
2025		161,167
2026		165,190
2027		169,307
2028		173,559
Thereafter		14,493
Total future lease payments		762,494
Less imputed interest		(181,146	)
Total operating lease liabilities	$	581,348

Litigation

From time to time, the Company may be subject to legal proceedings and claims that arise in the ordinary course of business. The Company does not believe that the outcome of those matters will have a material adverse effect to the financial position, operating results or cash flows. However, there can be no assurance such legal proceedings will not have a material impact.

The Company is not aware of any material claims outstanding or pending against the Company as of October 31, 2023.

Royalty Agreements

In 2013, the Company entered into an agreement (“Technology Agreement”) with its founder, conveying ownership of all intellectual property and rights to the Company. As part of that agreement, the Company will make royalty payments, based upon paid MyoVista device unit sales, as follows:

a)$500 on each of the first 2,400 MyoVista devices; and

b)$200 on each MyoVista device thereafter until royalties total $3,500,000.

The royalty obligation has a first priority security interest and pledge on the covered technology (as defined in the Technology Agreement, which essentially is comprised of the intellectual property of the MyoVista device) in priority to the debt holders of the $1.5M Notes and $1M Loan and Security Agreement as discussed further in Note 4.

Upon (i) the aggregate payment of $3,000,000 of royalties; (ii) the Common Stock having a closing quoted share price of $68.75 per share or more; or (iii) receipt by the Company of a bona fide offer valuing the Common Stock at $68.75 or more, then the secured interest and pledge shall be released.

In the event of a bankruptcy of the Company, any balance of the $3,500,000 royalty not paid at that point would accelerate and become an immediately due debt obligation of the Company with the benefit of the secured interest and pledge (if it remained at such time).

In December 2015, the Company entered into an agreement with The University Court of The University of Glasgow (“Glasgow”) for a non-exclusive license of the Glasgow algorithm interpretive analysis for the conventional ECG trace. The agreement was amended in March 2023, and as part of the agreement, the Company is required to make royalty payments, based upon MyoVista device unit sales dependent on sale volumes per year, subject to minimum annual fees. To date, such amounts have been expensed to research and development as the Glasgow algorithm has been part of the device development and will form part of the submission for FDA clearance of the MyoVista device.

Collaboration Agreements

On November 29, 2022, the Company entered into a multi-year Collaboration Agreement with Rutgers, The State University of New Jersey, to develop AI-based ECG algorithms for new or improved ECG indications, which is expected to accelerate our product development pipeline and further expand the clinical value of an ECG for low-cost detection of heart disease.

On September 20, 2023, the Company entered into multiple definitive license agreements (each a “License Agreement” and collectively, the “License Agreements”) with Icahn School of Medicine at Mount Sinai (“Mount Sinai”) to commercialize a range of AI cardiovascular algorithms developed by Mount Sinai as well as a memorandum of understanding for ongoing cooperation encompassing de-identified data access, on-going research, and the evaluation of the MyoVista. The License Agreements, of which

17

18

there are eleven in total, cover rights to thirteen AI cardiovascular algorithms, two data science methods for use with ECG waveforms and three filed patents.

The closing of the transactions contemplated under the Securities Purchase Agreement (the “MTS Transaction”), dated as of September 20, 2023 (the “Securities Purchase Agreement”), by and between the Company and Mount Sinai, and the effectiveness of the licenses under the License Agreements, are subject to the satisfaction or waiver of certain conditions, including a condition that the Company must complete one or more financings in which the Company receives aggregate gross proceeds of at least $5.0 million (the “Financing Requirement”) prior to December 31, 2023 (the “Closing Date”). The License Agreements may be terminated by Mount Sinai if the Company has not received aggregate gross total proceeds of at least $10.0 million in qualified transactions by June 30, 2024 (the “Additional Financing Requirement”). On November 15, 2023, the Company satisfied the Financing Requirement and, accordingly, the licenses under the License Agreements were deemed effective. See further discussion at Note 9.

Note 9. Subsequent Events

The Company has evaluated subsequent events after the balance sheet date of October 31, 2023, through the date of filing.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis is intended as a review of significant factors affecting our financial condition and results of operations for the periods indicated. The discussion should be read in conjunction with our unaudited financial statements and the notes presented herein included in this Quarterly Report on Form 10-Q and the audited financial statements and the related notes set forth in our 2023 Annual Report on Form 10-K. The discussion below contains forward-looking statements that are based upon our current expectations and are subject to uncertainty and changes in circumstances. Actual results may differ materially from these expectations due to inaccurate assumptions and known or unknown risks and uncertainties, including those identified in “Cautionary Note Regarding Forward-Looking Statements” and under “Risk Factors” as identified under Part 1, Item 1A of our 2023 Annual Report on Form 10-K.

Overview

We are a medical technology company focused on applying innovative AI-based technology to an ECG, also known as an “EKG,” to expand and improve an ECG’s clinical usefulness. Our objective is to make an ECG a far more valuable cardiac screening tool. HeartSciences’ first product candidate for FDA clearance, the MyoVista, is a resting 12-lead ECG that will incorporate HeartSciences’ first AI-based algorithm designed to provide diagnostic information related to cardiac dysfunction as well as conventional ECG information in the same test. In the future, we intend to incorporate additional AI-based algorithms in the MyoVista and develop a cloud-based platform to provide access to a range of AI-based ECG cardiovascular algorithms on an ECG hardware agnostic basis. The AI-based ECG algorithms provide diagnostic information related to structural heart disease which traditionally has only been available through the use of cardiac imaging. We believe, the MyoVista is particularly well suited for a frontline or point of care clinical setting and the initial revenue model, which involves the use of the MyoVista hardware, associated software and consumables for each test, is expected to be “razor-razorblade” as the cable connection to the electrodes used with the MyoVista are proprietary to HeartSciences, and new electrodes are used for every test performed. As further algorithms are made commercially available via the MyoVista or cloud-based platform we would expect to adopt revenue models based on algorithm usage and/or recurring subscriptions.

On September 20, 2023, we entered into multiple definitive license agreements (each a “License Agreement” and collectively, the “License Agreements”) with Icahn School of Medicine at Mount Sinai (“Mount Sinai”) to commercialize a range of AI-based cardiovascular algorithms developed by Mount Sinai as well as a memorandum of understanding for ongoing cooperation encompassing de-identified data access, on-going research, and the evaluation of the MyoVista. The License Agreements, of which there are eleven in total, cover rights to thirteen AI-based cardiovascular algorithms, two data science methods for use with ECG waveforms and three filed patents. These License Agreements closed on December 1, 2023.

Neither the MyoVista hardware, nor any of the AI-based ECG algorithms, are cleared for marketing by the FDA and our future success is dependent upon receiving FDA clearances. Additional funding may be required as part of achieving FDA clearance and thereafter would be required to support the sales launch of the MyoVista into the U.S., provide working capital and support further research and development (“R&D”).

We believe that there is currently no low-cost, front-line, medical device that is effective at screening broadly for many types of heart disease. As a result, we believe that frontline physicians face a significant challenge in determining if a patient has heart disease. Although many think of the ECG as the frontline test for heart disease, in 2012, the United States Preventive Services Task Force conducted an evaluation of conventional ECG testing and stated: “There is no good evidence the test, called an ECG, helps doctors predict heart risks any better than traditional considerations such as smoking, blood pressure and cholesterol levels in people with no symptoms.”

ECG devices record the electrical signals of a patient’s heart. The ECG is a ubiquitous, relatively low-cost, simple and quick test; it is portable and can be performed in a wide range of clinical settings by a non-specialist clinician or clinical aide. There are three basic categories of heart disease: electrical (such as an arrhythmia), structural (such as valvular disease) and ischemic (such as coronary artery disease, or CAD). Conventional resting ECGs have limited sensitivity in detecting structural and ischemic disease and are typically used for diagnosing cardiac rhythm abnormalities, such as atrial fibrillation, or acute coronary syndrome, such as a myocardial infarction which is also known as a heart attack. However, traditional ECGs have a limited role in identifying cardiac dysfunction associated with structural and ischemic disease.

HeartSciences has designed or licensed algorithms to help address these limitations and extend the clinical capability of an ECG to detect cardiac dysfunction or specific cardiovascular disease types. The first AI algorithm to be incorporated into the MyoVista has been designed by the Company and applies AI learning to the signal processed ECG signal to develop a proprietary algorithm designed to detect cardiac dysfunction caused by heart disease and/or age cardiac dysfunction. We recently proposed adjustment of the echocardiographic measurement thresholds to the FDA to reflect recent clinical findings in respect of ≥ 60 year old patients which we

20

21

believe will further increase the clinical value of the algorithm. The FDA has now confirmed this approach and we are in the process of updating our algorithm to reflect these updated echo measurement thresholds. The MyoVista has not yet received FDA clearance.

The editorial comment associated with the study titled “Prediction of Abnormal Myocardial Relaxation from Signal Processed Surface ECG” presented below discusses recent applications of machine learning to data derived from surface 12-lead ECGs in relation to cardiac dysfunction:

“These represent some of the most significant advances in electrocardiography since its inception, which has historically had a limited, if any, role in the evaluation of cardiac dysfunction. In the past, our cardiovascular community was resigned to the fact that surface ECGs are poor indicators for cardiac dysfunction.”

Khurram Nasir, MD, MPH, MSC, Department of Cardiology, Houston Methodist DeBakey Heart & Vascular Center, Houston, Texas, et. al., Journal of American College of Cardiology Editorial Comment Volume 76 Number 8 2020.

Almost all forms of heart disease, including CAD and structural disease, affect heart muscle, or cardiac, function prior to symptoms. Impaired cardiac function is first observed as impaired cardiac relaxation which is an early indicator of diastolic dysfunction and usually continues to increase in severity as heart disease progresses. The diastolic phase of the cardiac cycle occurs when the heart muscle relaxes (following contraction). Diastolic dysfunction may also be related to age-related cardiac dysfunction.

If we receive FDA clearance for our first product candidates, the MyoVista hardware and its associated cardiac dysfunction algorithm, our main target markets would be frontline healthcare environments in the U.S., such as primary care, to assist physician decision making in the cardiology referral process. Currently, cardiology referral decisions are often based on a patient’s risk factors and/or a conventional ECG test. Accordingly, many patients with heart disease are left undetected while no current treatment or intervention is required for most patients referred for cardiac imaging. We believe that adding the capability to detect cardiac dysfunction to a standard 12-lead resting ECG could help improve cardiac referral pathways and be valuable for patients, physicians, health systems and third-party payors.

New Class II devices, such as the MyoVista, require FDA premarket review. The MyoVista along with its proprietary software and hardware is classified as a Class II medical device by the FDA. Premarket review and clearance by the FDA for these devices is generally accomplished through the 510(k) premarket notification process or De Novo classification request, or petition process. We previously submitted an FDA De Novo classification request in December 2019 and, following feedback and communications with the FDA during and since that submission, we have been making modifications to our device, including our proprietary algorithm. We are part-way through a new, pivotal clinical validation study and have been undertaking device and algorithm development testing for a revised FDA submission. In August 2023, the FDA granted an industry first De Novo clearance and created a new Class II product code for cardiovascular machine learning-based notification software in respect of a hypertrophic cardiomyopathy algorithm and in December 2023 we received confirmation from the FDA that a change to submit the MyoVista, including it’s AI algorithm, under the 510(k) pathway would be acceptable. The 510(k) pathway is more common than De Novo and, on average, has a faster decision process than De Novo by the FDA. As a result, we now expect a revised submission to be filed during the first half of calendar year 2024. Assuming a submission under 510(k) in the first half of calendar year 2024, we would anticipate a determination by the FDA in 2024 which, if successful, would provide the ability to market and sell the MyoVista in the U.S. If successful, additional funding would be required to support the sales launch of the MyoVista in the U.S., provide working capital and support further R&D.

Recent Developments

Compliance with Nasdaq Listing Requirements

On December 21, 2022, we received notice from the Listing Qualifications Staff of The Nasdaq Stock Market, LLC, or Nasdaq, stating that we were not in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market, under Listing Rule 5550(b)(1) (the “Minimum Stockholders’ Equity Requirement”), because our stockholders’ equity of $1,082,676 as reported in our Quarterly Report on Form 10-Q for the quarter ended October 31, 2022 was below the required minimum of $2.5 million, and because, as of October 31, 2022, we did not meet the alternative compliance standards, relating to the market value of listed securities of $35 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or in two of the last three most recently completed fiscal years.

On February 3, 2023, we submitted to Nasdaq a plan to regain compliance with the Minimum Stockholders’ Equity Requirement. On February 8, 2023, Nasdaq notified us that they granted us an extension of up to 180 calendar days from December 21, 2022, or through June 19, 2023, to regain compliance. On June 20, 2023, we received a delist determination letter from Nasdaq advising us that Nasdaq determined that we did not meet the terms of the extension by the June 19, 2023 deadline.

21

22

On June 27, 2023, we submitted a hearing request to the Nasdaq Hearing Panel (the “Panel”) to appeal the delisting determination. In response to our request for a hearing, on June 27, 2023, we received a letter from Nasdaq stating that its delisting action has been stayed, pending a final decision by the Panel and a hearing will be held on August 17, 2023.

On August 2, 2023, we received a letter from the Listing Qualifications staff of Nasdaq indicating that, based upon the closing bid price of the Company’s Common Stock for the last 30 consecutive business days, the Company no longer met the requirement to maintain a minimum bid price of $1 per share (the “Minimum Bid Price Requirement”). In accordance with Nasdaq listing rules, we have until January 29, 2024 to regain compliance with the Minimum Bid Price Requirement. In the event we do not regain compliance during this period, we may be eligible to seek an additional 180 calendar day compliance period if we meet the Nasdaq continued listing requirement for market value of publicly held shares and all other initial listing standards, with the exception of the Minimum Bid Price Requirement, and provide written notice to Nasdaq of our intent to cure the deficiency during this second compliance period.

The Company attended an August 17, 2023 hearing before the Panel, and requested the continued listing of its securities on the Nasdaq Capital Market pending its return to compliance with the Minimum Stockholder's Equity Requirement and Minimum Bid Price Requirement.

On August 28, 2023, the Company received a decision from the Panel granting the Company's request for continued listing on the Nasdaq Capital Market, subject to the Company demonstrating compliance with the Minimum Stockholders’ Equity Requirement on or before November 21, 2023, and certain other conditions. In addition, the Company has until January 29, 2024, to demonstrate compliance with the Minimum Bid Price Requirement.

On November 22, 2023, the Company was formally notified by the Panel that the Company has demonstrated compliance with the Minimum Stockholders’ Equity Requirement. The Company will be subject to a Mandatory Panel Monitor through November 22, 2024.

Equity Distribution Agreement

On September 18, 2023, we entered into an EDA with Maxim Group LLC as sales agent pursuant to which we may offer and sell up to $3.25 million of our shares of Common Stock in an at-the-market offering. The shares may be issued and sold from time to time through or to the placement agent acting as sales agent or principal pursuant to our shelf registration statement on Form S-3 (the “Shelf S”), as filed with the SEC on September 18, 2023. Pursuant to General Instruction I.B.6 of Form S, we may not sell the shelf securities in a public primary offering with a value exceeding more than one of the aggregate market value of its voting and non-voting ordinary shares held by non-affiliates in any 12 month period as long as the aggregate market value of our outstanding ordinary shares held by non-affiliates is less than $75 million. The $3.25 million shares comprised of Common Stock that may be offered, issued and sold under the at-the-market offering prospectus is included in the $50.0 million of securities that may be offered, issued, and sold by us under the base prospectus of the Shelf S-3.

$10.0 million worth of shares of Common Stock from time to time through the sales agent. On November 11, 2023, we entered into Amendment No. 2 of the EDA with Maxim pursuant to which, we may issue and sell up to $15.0 million shares of Common Stock through the sales agent.

Debt conversion

As previously disclosed in our Current Report on Form 8-K filed with the SEC on January 24, 2023, we entered into Amendment No. 4 to the $1M Loan and Security Agreement with FRV and John Q. Adams. Pursuant to the $1M Loan and Security Agreement, a secured promissory note in the original principal amount of $500,000 was issued to FRV and a secured promissory note in the original principal amount of $500,000 was issued to John Q. Adams. The Loan and Security Agreement was further amended on September 29, 2023 to amend the dates on which principal and accrued interest is due under the JQA Note. As consideration for such extension, we issued FRV and Mr. Adams $1M Lender Warrants to purchase an aggregate of 200,000 shares of Common Stock at an exercise price of $0.44 per share.

On November 16, 2023, we entered into the Adams Note Conversion Letter Agreements with Mr. Adams. Pursuant to the Adams Note Conversion Letter Agreement, in consideration for the conversion of the principal and interest amounts due under the JQA Note, on November 16, 2023, we: (1) issued 3,656,288 shares of Common Stock to Mr. Adams; and (2) entered into the Adams Warrant Amendment, amending the $1M Lender Warrants owned by Adams to reduce the exercise price of an aggregate of 107,575 $1M Lender Warrants to $0.16 per share.

Cost of sales consists primarily of costs related to materials, components and subassemblies. Cost of sales also includes certain direct costs such as those incurred for shipping and freight.

Operating Expenses

Our operating expenses have consisted solely of research and development expenses and selling, general and administrative expenses.

Research and Development Expenses

Our research and development activities primarily consist of clinical, regulatory, engineering and research work associated with our MyoVista device. Research and development expenses include payroll and personnel-related costs for our research and development, clinical and regulatory personnel, including expenses related to stock-based compensation for such employees, consulting services, clinical trial expenses, regulatory expenses, prototyping and testing. Research and development expenses also include costs attributable to clinical trial expenses including clinical trial design, site development and study costs, data, related travel expenses, the cost of products used for clinical activities, internal and external costs associated with regulatory compliance and patent costs. We have expensed research and development costs as they have been incurred.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses consist of payroll and personnel-related costs for field support personnel, business development, consulting, stock-based compensation, and for administrative personnel that support our general operations such as executive management and financial accounting.

Summary of Statements of Operations for the three and six months ended October 31, 2023 compared with the three and six months ended October 31, 2022:

Revenues were $4,000 and costs of sales were $2,000 for the three months ended October 31, 2023. Revenues were $4,000 and costs of sales were $2,000 for the six months ended October 31, 2023 compared to revenues of $3,000 and costs of sales of $2,000 for

24

25

the six months ended October 31, 2022. Our revenues to date have been mainly generated in the establishment of distributor relationships outside the United States as part of obtaining feedback during product development and improvement. The decrease in revenue, and related decrease in cost of sales, is due to our proactive reduction in new international distributor engagement in the run up to FDA submission and until we update our certificate of conformity, called a CE Mark, under the new European Union Medical Device Regulation regime to reflect hardware and software improvements being incorporated into the device for FDA submission.

Research and development expenses were $757,000 and $1.3 million for the three and six months ended October 31, 2023, representing a decrease of $92,000, or 11%, and an increase of $40,000, or 3%, when compared to the same periods in 2022. For the three months ended October 31, 2023, decrease is primarily due to reductions in clinical trial related expenditures resulting from the completion of patient enrollment in our clinical study for FDA submission. For the six months ended October 31, 2023, the increase is primarily due to personnel expenses.

Selling, general, and administrative expenses were $815,000 and $1.6 million for the three and six months ended October 31, 2023, representing a decrease of $110,000, or 12%, and a decrease of $342,000, or 18%, when compared to the same periods in 2022. For the three and six months ended October 31, 2023, the decrease is primarily due to reduction in legal expenses, reduced D&O insurance premiums, and related supplier credits.

Interest expense during the three and six months ended October 31, 2023, of $178,000 and 215,000, respectively, is related to interest on the $1M Loan and Security Agreement, warrants issued as consideration for extension of the JQA interest maturity date in October 2023, and interest and debt service amortization related to MSW Note. Interest expense during the three and six months ended October 31, 2022 of $33,000 and $176,000, respectively, is related to interest on the $1M Loan and Security Agreement and debt service amortization related to the Bridge Notes for approximately half of the quarter ended July 31, 2022. All of the Bridge Notes and accrued interest were converted to equity upon consummation of the IPO in June 2022.

Liquidity and Capital Resources

Going Concern Considerations

We have incurred significant losses and have experienced negative cash flows from operations since inception. At October 31, 2023, we had an accumulated deficit of $63.9 million and stockholder's deficit of $1.6 million compared to an accumulated deficit of $60.8 million and stockholder's equity of $0.2 million as of April 30, 2023. At October 31, 2023, we incurred a net loss of $3.1 million for the six month period then ended and a net loss of $3.4 million for the six month period ended October 31, 2022.

During the year ended April 30, 2023, we raised approximately $5.2 million in net proceeds from the sale of Common Stock and Warrants in our IPO and raised approximately $1.3 million from warrant exercises.

On March 10, 2023, we entered into the Lincoln Park Purchase Agreement providing for the purchase, from time to time at our discretion, of up to $15.0 million of our Common Stock, over the 36-month term of the agreement. Actual sales of shares of Common Stock will depend on a variety of factors to be determined by us from time to time. The net proceeds received from these purchases will depend on the frequency and prices at which we sell shares of our Common Stock to Lincoln Park. As of the date of this Quarterly Report, we have received approximately $1.1 million from the sale of Common Stock pursuant to the Lincoln Park Purchase Agreement. We expect that any proceeds received from such sales to Lincoln Park will be used for working capital and general corporate purposes.

On September 18, 2023, we entered into an EDA with Maxim Group LLC as sales agent pursuant to which we may offer and sell up to $3.25 million of our shares of Common Stock in at-the-market offerings. The EDA was further amended on November 9, 2023 and again on November 17, 2023, to increase the amount of shares of Common Stock we may sell to up to $15.0 million. The shares may be issued and sold from time to time through or to the placement agent acting as sales agent or principal pursuant to our shelf registration statement on the Shelf S-3, as filed with the SEC on September 18, 2023. As of the date of this Quarterly Report, we have received approximately $9.2 million in net proceeds, after Maxim fees, legal fees and other costs, from the sale of Common Stock pursuant to the amended EDA. We expect that any proceeds received from such sales under the ATM Facility will be used for working capital and general corporate purposes

In September 2023, the Company entered into the MSW Note for up to $1.0 million, drawn in installments consisting of (i) $0.25 million on or prior to September 8, 2023, (ii) ) $0.25 million on or prior to September 20, 2023, and (iii) further drawdowns of up to $0.5 million in such amounts and such times to be mutually agreed upon between the Company and lender. As of October 31, 2023, the Company has drawn $0.5 million pursuant to the terms of the note. In November 2023, the MSW Note was converted into shares of Common Stock.

25

26

As of the date of this Annual Report, we have begun the process of an offering with Maxim Group, for the sale of up to $8.0 million worth of shares of our Common Stock, on a best-efforts basis. This offering has not yet been declared effective by the SEC.

Our cash requirements are, and will continue to be, dependent upon a variety of factors. We expect to continue devoting significant capital resources to R&D, clinical studies and go-to-market strategies. We will need to continue to raise capital through the sale of additional equity securities, debt, or capital inflows from strategic partnerships, however we can provide no assurance that that we will be able to consummate the sale of any such securities or strategic relationships will be available on terms acceptable to us, if at all.

Liquidity

Since our inception, we have raised capital through the public and private sale of debt and equity. As of October 31, 2023, we had cash of approximately $0.1 million and negative working capital of approximately $1.7 million.

The table below presents our cash flows for the periods indicated:

	Six months ended October 31,
U.S. dollars, in thousands	2023			2022
	(Unaudited)
Net cash used in operating activities	$	(2,392	)	$	(2,892	)

Net cash provided by financing activities	$	839		$	5,057
Net change in cash and cash equivalents during the period	$	(1,560	)	$	2,158

Operating Activities

Net cash used by our operating activities of $2.4 million during the six months ended October 31, 2023 is primarily due to our net loss of $3.1 million plus $561,000 in non-cash expenses plus $162,000 of net changes in operating assets and liabilities.

Net cash used by our operating activities of $2.9 million during the six months ended October 31, 2022 is primarily due to our net loss of $3.4 million plus $141,000 in non-cash expenses plus $347,000 of net changes in operating assets and liabilities.

Financing Activities

Net cash provided by financing activities of $0.8 million during the six months ended October 31, 2023 is primarily from the issuance of Common Stock under the Equity Line, ATM Facility, and net proceeds from the MSW Note.

Net cash provided by financing activities of $5.1 million during the six months ended October 31, 2022 is primarily from the issuance of Common Stock in our IPO.

From November 1, 2023, through the date of filing, the Company has raised additional capital of approximately $9.3 million, net of fees, from the Equity Line and ATM Facility.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates from the information provided in Item 7, “Management's Discussion and Analysis of Financial Condition and Results of Operations,” included in our 2023 Annual Report on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not required to be provided by a smaller reporting company.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

The Company has adopted and maintains disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in the reports filed under the Exchange Act, such as this Quarterly Report on Form 10-Q, is collected, recorded, processed, summarized and reported within the time periods specified in the rules of the SEC. The Company's disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to

26

27

management to allow timely decisions regarding required disclosure. Based upon the most recent evaluation of internal controls over financial reporting, our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer) determined that our disclosure controls and procedures were not effective as of October 31, 2023 as a result of identified material weaknesses in our internal control over financial reporting. The identified material weaknesses were as follows: (i) lack of proper approval processes and review processes and documentation for such reviews; (ii) we did not maintain sufficient U.S. GAAP and SEC accounting resources commensurate with those required of a public company; and (iii) insufficient number of staff to maintain optimal segregation of duties and levels of oversight. We have taken and continue to take remedial steps to improve our internal controls over financial reporting, which includes hiring additional accounting and financial reporting personnel and implementing additional policies, procedures, and controls. We cannot assure you that these measures will significantly improve or remediate the material weaknesses described above. Management is monitoring the effectiveness of these and other processes, procedures and controls and will make any further changes deemed appropriate. Management believes the foregoing actions will effectively remediate the material weaknesses, however, our material weaknesses will not be considered remediated until the above controls are in place for a period of time, the controls are tested, and management concludes that these controls are properly designed and operating effectively.

Changes in Internal Control Over Financial Reporting

Except as described above with respect to the remediation steps we are taking, there have been no changes in our internal control over financial reporting during the quarter ended October 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

CEO and CFO Certifications

Exhibits 31.1 and 31.2 to this Quarterly Report are the Certifications of our Chief Executive Officer and Interim Chief Financial Officer, respectively. These Certifications are required in accordance with Section 302 of the Sarbanes-Oxley Act (the “Section 302 Certifications”). This Item 4 of this Quarterly Report, which you are currently reading, is the information concerning the evaluation referred to above and in the Section 302 Certifications and this information should be read in conjunction with the Section 302 Certifications for a more complete understanding of the topics presented.
