NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization, Use of Estimates and Basis of Presentation

Champions Oncology, Inc. (the "Company") is a technology-enabled research organization engaged in creating technology solutions to be utilized in drug discovery and development. The Company's research center operates in both regulatory and non-regulatory environments and consists of a comprehensive set of computational and experimental research platforms. Its pharmacology, biomarker, and data platforms are designed to facilitate drug discovery and development at lower costs and increased speeds.

The Company has four operating subsidiaries: Champions Oncology (Israel), Limited, Champions Biotechnology U.K., Limited, Champions Oncology, S.R.L. (Italy), and Corellia A.I.. For the three and nine months ended January 31, 2024 and 2023, there were no revenues earned by these subsidiaries.

The Company’s functional currency for its foreign subsidiaries is the U.S. dollar. Transaction gains and losses are recognized in earnings. The Company is subject to foreign exchange rate fluctuations in connection with the Company’s international operations.

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. Intercompany transactions and accounts have been eliminated. Certain information related to the Company’s organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, or GAAP, has been condensed or omitted. The April 30, 2023 condensed consolidated balance sheet in the accompanying interim condensed consolidated financial statements was derived from audited consolidated financial statements. The accounting policies followed in the preparation of these unaudited condensed consolidated financial statements are consistent with those followed in the Company’s annual consolidated financial statements for the fiscal year ended April 30, 2023, as filed in the Company's Annual Report on Form 10-K with the SEC on July 24, 2023 (the "Annual Report"). In the opinion of management, these unaudited condensed consolidated financial statements contain all material adjustments necessary to fairly state our financial position, results of operations and cash flows for the periods presented and the presentations and disclosures herein are adequate when read in conjunction with the Company’s 2023 Annual Report. The results of operations for the interim periods are not necessarily indicative of the results of operations for a full fiscal year.

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

Note 2. Significant Accounting Policies

Cash and Cash Equivalents

The Company considers only those investments which are highly liquid, readily convertible to cash, and with original maturities of three months or less to be cash equivalents. As of January 31, 2024 the Company had cash equivalents of approximately $2.9 million and, as of April 30, 2023, the Company had no cash equivalents.

The Company is subject to a concentration of credit risk in the form of its cash deposits held at multiple banking institutions. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. As of January 31, 2024 and April 30, 2023, the Company had approximately $3.3 million and $8.7 million in excess of the FDIC insured limit, respectively.

Liquidity

The Company's liquidity needs have typically arisen from the funding of our research and development programs and the launch of new products, working capital requirements, and other strategic initiatives. Recently, the Company has met these cash requirements through cash on hand, working capital management, and sales of products and services. In the past, the Company has also received proceeds from certain private placements and public offerings of its securities. For the nine months ended January 31, 2024, the Company had a net loss of approximately $7.2 million and cash used in operations of approximately $4.3 million. As of January 31, 2024, the Company had an accumulated deficit of approximately $84.5 million and cash on hand of approximately $4.5 million. The Company believes that cash on hand, together with expected cash to be provided from operations during fiscal year 2025, are adequate to fund operations through at least 12 months from the filing of this Quarterly Report on Form 10-Q (this "Report"). However, should the Company's revenue expectations not materialize, the Company believes it has cost reduction strategies that could be implemented without disrupting the business or restructuring the Company. Should the Company be required to raise additional capital, there can be no assurance that management would be successful in raising such capital on terms acceptable to us, if at all.

Fair Value

The carrying value of cash, accounts receivable, prepaid expenses, and other current assets, accounts payable, and accrued liabilities approximate their fair value based on the liquidity or the short-term maturities of these instruments. The fair value hierarchy promulgated by GAAP consists of three levels:

•Level one — Quoted market prices in active markets for identical assets or liabilities;

•Level two — Inputs other than level one inputs that are either directly or indirectly observable; and

•Level three — Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use.

Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter. As of January 31, 2024 the Company had assets measured at fair value on a recurring and/or non-recurring basis as follows:

(in 000s)	January 31, 2024
	Level 1		Level 2		Level 3
Cash Equivalents:
Money market fund	2,854		—		—
Total	$	2,854	$	—	$	—

As of January 31, 2024, the Company had no liabilities measured at fair value on a recurring and/or non-recurring basis. As of April 30, 2023, the Company had no assets or liabilities measured at fair value on a recurring and/or non-recurring basis.

Earnings Per Share

Basic net income or loss per share is computed by dividing the net income or loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing the net income for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s common stock options.

As of January 31, 2024 and 2023, all of the Company's potential common stock is considered anti-dilutive.

The following table reflects the total potential share-based instruments outstanding at January 31, 2024 and 2023 including those that could have an effect on the future computation of dilution per common share, had their effect not been anti-dilutive due to the Company's net losses in the related periods:

	January 31,
	2024	2023
Total common stock equivalents	1,903,747	1,779,167

Income Taxes

    Deferred income taxes have been provided to show the effect of temporary differences between the recognition of expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. In assessing the realizability of deferred tax assets, the Company assesses the likelihood that deferred tax assets will be recovered through tax planning strategies or from future taxable income, and to the extent that recovery is not likely or there is insufficient earnings history, a valuation allowance is established. The Company's ability to utilize net operating losses (“NOL”) carryforwards to offset future taxable income would be limited if the Company had undergone or were to undergo an “ownership change” within the meaning of Section 382 of the Internal Revenue Code (the “IRC”). The Company adjusts the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized. Changes in valuation allowances from period to period are included in the tax provision in the period of change. As of January 31, 2024 and April 30, 2023, the Company provided a valuation allowance for all net deferred tax assets as it is more likely than not that the assets will not be recovered based on an insufficient history of earnings.

The Company reflects tax benefits only if it is more likely than not that the Company will be able to sustain the tax position, based on its technical merits.  If a tax benefit meets this criterion, it is measured and recognized based on the largest amount of benefit that is cumulatively greater than 50% likely to be realized.  The Company recorded $181,000 of liabilities related to uncertain tax positions relative to one of its foreign operations as of January 31, 2024 and April 30, 2023.

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company did not recognize interest or penalties on its consolidated statements of operations during the three and nine-month periods ended January 31, 2024 and 2023. The Company does not anticipate unrecognized tax benefits will be recorded during the next 12 months.

The provision for income taxes for the three months ended January 31, 2024 and 2023 was $11,000 and $17,000, respectively. The provision for income taxes for the nine months ended January 31, 2024 and 2023 was $49,000 and $48,000, respectively. The provision is mainly attributable to taxable income earned in Israel and/or Italy relating to transfer pricing.     

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") 606 ("ASC 606"), Revenue from Contracts with Customers. Under this standard, companies recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services.

All revenue is generated from contracts with customers. The Company's arrangements are service type contracts that mainly have a duration of less than a year. The Company recognizes revenue when control of these services is transferred to the customer in an amount, referred to as the transaction price, that reflects the consideration to which the Company is expected to be entitled in exchange for those services. The Company determines revenue recognition utilizing the following five steps: (1)

10

identification of the contract with a customer, (2) identification of the performance obligations in the contract (promised goods or services that are distinct), (3) determination of the transaction price, (4) allocation of the transaction price to the performance obligations, and (5) recognition of revenue when, or as, the Company transfers control of the product or service for each performance obligation. The Company records revenues net of any tax assessments by governmental authorities, such as value added taxes, that are imposed on and concurrent with specific revenue generating transactions.

The majority of the Company's revenue arrangements are service contracts that are completed within a year or less. There are a few contracts that range in duration between 1 and 3 years. Substantially all of the Company's performance obligations, and associated revenue, are transferred to the customer over time. Most of the Company's contracts can be terminated by the customer without cause. In the event of termination, the Company's contracts provide that the customer pay the Company for services rendered through the termination date. The Company generally receives compensation based on a predetermined invoicing schedule relating to specific milestones for that contract.

Amendments to contracts are common. The Company evaluates each amendment which meets the criteria of a contract modification under ASC 606. Each modification is further evaluated to determine whether the contract modification should be accounted for as a separate contract or as a continuation of the original agreement.

The Company accounts for amendments as a separate contract as they meet the criteria under ASC 606-10-25-12.

Pharmacology Study and Other Services

The Company generally enters into contracts with customers to provide oncology services with payments based on fixed-fee arrangements. At contract inception, the Company assesses the services promised in the contracts with customers to identify the performance obligations in the arrangement. The Company's fixed-fee arrangements for oncology services are considered a single performance obligation because the Company provides a highly-integrated service.

The Company recognizes revenue over time using a progress-based input method since there is no single output measure that would fairly depict the transfer of control over the life of the performance obligation. Revenue is recognized for the single performance obligation over time due to the Company's right to payment for work performed to date and the performance does not create an asset with an alternative use. The Company recognizes revenue as portions of the overall performance obligation are completed as this best depicts the progress of the performance obligation.

Incremental Costs of Obtaining a Contract (Sales Commissions)

Under ASC 606, the costs of obtaining a contract can be expensed immediately, rather than capitalized and amortized, if the amortization period is one year or shorter. Sales commissions for the Company represent contract costs with a term of one year or less. Therefore, under ASC 606, the Company elected the practical expedient to expense these costs as incurred.

Variable Consideration

In some cases, contracts provide for variable consideration that is contingent upon the occurrence of uncertain future events, such as the success of the initial performance obligation. Variable consideration is estimated at the expected value or at the most likely amount depending on the type of consideration. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The estimate of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.

Trade Receivables, Unbilled Services and Deferred Revenue

In general, billings and payments are established by contractual provisions including predetermined payment schedules, which may or may not correspond to the timing of the transfer of control of the Company's services under the contract. In general, the Company's intention in its invoicing (payment terms) is to maintain cash neutrality over the life of the contract. Upfront payments, when they occur, are intended to cover certain expenses the Company incurs at the beginning of the contract. Neither the Company nor its customers view such upfront payments and contracted payment schedules as a means of financing. Unbilled services primarily arise when the revenue recognized exceeds the amount billed to the customer. Such situations occur due to divergences between revenue recognition and the invoicing milestones which are based on predetermined payment terms.

11

Deferred revenue consists of unearned payments received in excess of revenue recognized. As the contracted services are subsequently performed and the associated revenue is recognized, the deferred revenue balance is reduced by the amount of the revenue recognized during the period. Deferred revenue is classified as a current liability on the condensed consolidated balance sheet as the Company expects to recognize the associated revenue in less than one year.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, “Financial Instruments—Credit Losses” (Topic 326). This ASU represents a significant change in the current accounting model by requiring immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred, which delayed recognition of expected losses that might not yet have met the threshold of being probable. The Company adopted ASU 2016-03 on April 1, 2023 and the adoption did not have any material effect on our condensed consolidated financial statements and related disclosures.

The first asset, laboratory equipment, was acquired for $128,000 and had accumulated depreciation of $62,000, resulting in a loss of $66,000 upon disposal. The second asset, acquired software, was purchased for $33,000 and had accumulated amortization of $18,000, resulting in a loss of $15,000 upon disposal.

Capitalized Software Development Costs Under a Hosting Arrangement

The Company accounts for the cost of computer software obtained or developed for internal use as well as the software development and implementation costs associated with a hosting arrangement ("internal-use software") that is a service contract

13

in accordance and with ASC 350, Intangibles - Goodwill and Other ("ASC-350"). We capitalize certain costs in the development of our internal-use software when the preliminary project stage is completed and it is probable that the project itself will be completed and the software will perform as intended. These capitalized costs include personnel and related expenses for employees and costs of third-party consultants who are directly associated with and who devote time to these internal-use software projects. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Costs incurred for significant upgrades, increased functionality, and enhancements to the Company's internal-use software solutions are also capitalized. Costs incurred for training, maintenance, and minor modifications are expensed as incurred. Capitalized software development costs are amortized using the straight-line method over an estimated useful economic life of three years.

The Company has capitalized development and implementation costs in accordance with accounting guidance for its Lumin platform. Lumin is the Company's oncology data-driven software program and data tool which operates as SaaS. These capitalized costs represent salaries, including direct payroll-related costs, certain software development consultant expenses and molecular sequencing programming costs incurred in the engineering and coding of the software development. Total capitalized gross asset costs for the Lumin platform that was launched and placed into service were $1.9 million. During the fourth quarter of fiscal year 2023, an impairment loss was recognized equal to the amount by which the carrying amount exceeded the future net revenues, or, its net book value at April 30, 2023 of $807,000. Amortization expense related to this asset was $0 and $157,000 for the three months ended January 31, 2024 and 2023, respectively, and $0 and $471,000 for the nine months ended January 31, 2024 and 2023, respectively.

Finance Lease

During fiscal year 2023, the Company recognized a finance lease for laboratory equipment. This equipment was obtained as the result of a laboratory supplies purchase commitment with costs of approximately $368,000 at inception through June 2027. Cash payments for this lease are in the form of consideration for purchasing lab supplies under a purchase commitment agreement. The present value of the minimum future obligations of $368,000 was calculated based on an interest rate of 3.5%. Depreciation and amortization expense related to this finance lease was $17,800 and $17,100 for the three months ended January 31, 2024 and 2023, respectively, and $52,800 and $45,100 for the nine months ended January 31, 2024 and 2023, respectively.

During fiscal year 2022, the Company recognized a finance lease for laboratory equipment. This equipment was obtained as the result of a laboratory supplies purchase commitment with costs of approximately $370,000 at inception through December 2025. Cash payments for this lease are in the form of consideration for purchasing lab supplies under a purchase commitment agreement. At the commencement of the commitment, the present value of the minimum future obligations of $370,000 was calculated based on an interest rate of 3.25%. Depreciation and amortization expense related to this finance lease was $18,700 and $18,000 for the three months ended January 31, 2024 and 2023, respectively, and $55,600 and $54,000 for the nine months ended January 31, 2024 and 2023, respectively.

The liabilities related to these finance leases are classified under other current liability and other non-current liabilities on the Company's balance sheet. The weighted average remaining lease term of these leases is 2.83 years.

The Company has in place a 2021 Equity Incentive Plan and 2010 Equity Incentive Plan (collectively, the "Plans"). In general, these Plans provide for stock-based compensation to the Company’s employees, directors and non-employees. The Plans also provide for limits on the aggregate number of shares that may be granted, the term of grants and the strike price of option awards.

2021 Equity Incentive Plan

As part of the 2021 Annual Shareholders Meeting, shareholders approved the adoption of the 2021 Equity Incentive Plan (“2021 Equity Plan”). The purpose of the 2021 Equity Plan is to grant (i) Non-statutory Stock Options; (ii) Incentive Stock Options; (iii) Restricted Stock Awards; and/or (iv) Stock Appreciation Rights (collectively, stock-based compensation) to its employees, directors and non-employees. Total stock awards under the 2021 Equity Plan shall not exceed 2 million shares of common stock. Options and Stock Appreciation Rights expire no later than ten years from the date of grant and the awards vest as determined by the Company's Board of Directors. Options and Stock Appreciation Rights have a strike price not less than 100% of the fair market value of the common stock subject to the option or right at the date of grant. As of January 31, 2024, approximately 1.3 million shares were available for issue under this plan.

2010 Equity Incentive Plan

On February 18, 2011, shareholders owning a majority of the issued and outstanding shares of the Company executed a written consent approving the 2010 Equity Incentive Plan (“2010 Equity Plan”). The purpose of the 2010 Equity Plan is to grant (i) Non-statutory Stock Options; (ii) Restricted Stock Awards; and (iii) Stock Appreciation Rights (collectively, stock-based compensation) to its employees, directors and non-employees. Total stock awards under the 2010 Equity Plan shall not exceed 30 million shares of common stock. Options and Stock Appreciation Rights expire no later than ten years from the date of grant and the awards vest as determined by the Board of Directors. Options and Stock Appreciation Rights have a strike price not less than 100% of the fair market value of the common stock subject to the option or right at the date of grant. After February 2021, no more shares were available to be issued from this plan.

Stock Option Grants

Black-Scholes assumptions used to calculate the fair value of options granted during the three and nine months ended January 31, 2024 and 2023 were as follows:

	Three Months Ended January 31,		Nine Months Ended January 31,

Share Repurchase Program

On March 29, 2023, the Board of Directors approved a share repurchase program authorizing the Company to purchase up to an aggregate of $5.0 million of the Company’s common stock. The share repurchase program is designed in accordance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The shares may be purchased from time to time in the open market, as permitted under applicable rules and regulations, at prevailing market prices. The timing and amount of repurchases will depend on market conditions, share price, applicable legal requirements and other factors. The program does not obligate the Company to acquire a minimum number of shares. As of January 31, 2024, the Company had purchased approximately 120,300 shares of its common stock, at an average price of $5.73 per share, totaling approximately $708,000 and leaving an available balance of approximately $4.3 million authorized by the Board for use in the program as of that date.

Note 7. Leases

The Company accounts for its leases under FASB ASC Topic 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use ("ROU") asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease, if applicable, or the Company’s incremental borrowing rate. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term.

Operating Leases

The Company currently leases certain office equipment and its office and laboratory facilities under non-cancelable operating leases. Rent expense for operating leases is recognized on a straight-line basis over the lease term from the lease commencement date through the scheduled expiration date. Rent expense totaled $454,000 and $475,000 for the three months ended January 31, 2024 and 2023, respectively. Rent expense totaled $1.4 million for both the nine months ended January 31, 2024 and 2023. The Company considers its facilities adequate for its current operational needs.

The Company leases the following facilities:

Note 9. Commitments and Contingencies

Legal Matters

The Company is not currently party to any legal matters to its knowledge. The Company is not aware of any other matters that would have a material impact on the Company’s financial position or results of operations.

Registration Payment Arrangements

The Company has entered into an Amended and Restated Registration Rights Agreement in connection with the March 2015 private placement. This Amended and Restated Registration Rights Agreement contains provisions that may call for the Company to pay penalties in certain circumstances. This registration payment arrangement primarily relates to the Company’s ability to file a registration statement within a particular time period, have a registration statement declared effective within a particular time period and to maintain the effectiveness of the registration statement for a particular time period. The Company has not accrued any liquidated damages associated with the Amended and Restated Registration Right Agreement as the Company has filed the required registration statement and anticipates continued compliance with the agreement.

Royalties

The Company contracts with third-party vendors to license tumor samples for development into Patient Derived Xenograft (PDX) models and use in our pharmacology TOS business. These types of arrangements have an upfront fee ranging from nil to $30,000 per tumor sample depending on the successful growth of the tumor model and ability to develop them into a sellable product. The upfront costs are expensed as incurred. In addition, under certain agreements, for a limited period of time, the Company is subject to royalty payments if the licensed tumor models are used for sale in our TOS business, ranging from 2% to 20% of the contract price after recouping certain initiation costs. Some of these arrangements also set forth an annual minimum royalty due regardless of tumor models used for sale. For the three months ended January 31, 2024 and 2023, we have recognized approximately $114,000 and $21,000, respectively, in expense related to these royalty arrangements. For the nine months ended January 31, 2024 and 2023, we have recognized approximately $240,000 and $129,000, respectively, in expense related to these royalty arrangements.

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

The following discussion of our historical results of operations and our liquidity and capital resources should be read in conjunction with the condensed consolidated financial statements and related notes that appear elsewhere in this Report and our 2023 Annual Report.

Forward-Looking Statements

This Report contains certain “forward-looking statements,” which include information relating to future events, future financial performance, strategies, expectations, competitive environment, regulation, and availability of resources. These forward-looking statements include, without limitation, statements regarding: proposed new programs; expectations that regulatory developments or other matters will not have a material adverse effect on our financial position, results of operations, or liquidity; statements concerning projections, predictions, expectations, estimates, or forecasts as to our business, financial and operational results, and future economic performance; and statements of management’s goals and objectives and other similar expressions concerning matters that are not historical facts. Words such as “may,” “should,” “could,” “would,” “predicts,” “potential,” “continue,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates” and similar expressions, as well as statements in future tense, identify forward-looking statements.

Forward-looking statements should not be read as a guarantee of future performance or results and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking statements are

18

based on information available at the time those statements are made or management’s good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements.

Forward-looking statements speak only as of the date the statements are made. Factors that could cause actual results to differ from those discussed in the forward-looking statements include, but are not limited to, those described in “Risk Factors” in Part I, Item 1A of our 2023 Annual Report, as updated in our subsequent reports filed with the SEC, including any updates found in Part II, Item 1A of this or other reports on Form 10-Q, if any. You should not put undue reliance on any forward-looking statements. We assume no obligation to update forward-looking statements to reflect actual results, changes in assumptions, or changes in other factors affecting forward-looking information, except to the extent required by applicable securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

Overview and Recent Developments

We are a technology-enabled research organization engaged in creating transformative technology solutions to be utilized in drug discovery and development. Our research center consists of a comprehensive set of computational and experimental research platforms. Our pharmacology, biomarker, and data platforms are designed to facilitate drug discovery and development at lower costs and increased speeds. We perform studies which we believe may predict the efficacy of experimental oncology drugs or approved drugs as stand-alone therapies or in combination with other drugs and can simulate the results of human clinical trials. These studies include in vivo studies that rely on implanting multiple tumors from our TumorBank in mice and testing the therapy of interest on these tumors. Studies may also include bioinformatics analysis that reveal the differences in the genetic signatures of the tumors that responded to a therapy as compared to the tumors that did not respond. Additionally, we provide computational or experimental support to identify novel therapeutic targets, select appropriate patient populations for clinical evaluation, identify potential therapeutic combination strategies, and develop biomarker hypothesis of sensitivity or resistance. These studies include the use of our in vivo, ex vivo, analytical and computational platforms.

We are engaged in the development and sale of advanced technology solutions and products to personalize the development and use of oncology drugs through our Translational Oncology Solutions ("TOS"). This technology ranges from computational-based discovery platforms, unique oncology software solutions, and innovative and proprietary experimental tools such as in vivo, ex vivo and biomarker platforms. Utilizing our TumorGraft Technology Platform (the "Platform"), a comprehensive bank of unique, well characterized models, we provide select services to pharmaceutical and biotechnology companies seeking personalized approaches to drug development. By performing studies to predict the efficacy of oncology drugs, our Platform facilitates drug discovery with lower costs and increased speed of drug development as well as increased adoption of existing drugs.

We offer Lumin Bioinformatics ("Lumin"), an oncology data-driven Software as a Service (SaaS) program. Our Lumin software contains comprehensive information derived from our research services and clinical studies. Lumin leverages our large Datacenter coupled with analytics and artificial intelligence to provide a robust tool for computational cancer research. Insights developed using Lumin can provide the basis for biomarker hypotheses, reveal potential mechanisms of therapeutic resistance, and guide the direction of additional preclinical evaluations.

Our drug discovery and development business leverages the computational and experimental capabilities within our platforms. Our discovery strategy utilizes our Datacenter, coupled with artificial intelligence and other advanced computational analytics, to identify novel therapeutic targets. We then employ the use of our proprietary experimental platforms to validate these targets for further drug development efforts.

We have a pipeline of targets at various stages of discovery and validation, with a select group that has progressed to therapeutic development. Our commercial strategy for the validated targets and therapeutics established from this business is wide-ranging and still being developed. It will depend on many factors, and will be specific for each target or therapeutic area identified. All expenses associated with this part of our business are research and development and are expensed as incurred.

We regularly evaluate strategic options to create additional value from our drug discovery business, which may include, but are not limited to, potential spin-out transactions or capital raises.

Liquidity and Capital Resources

19

Our liquidity needs have typically arisen from the funding of our research and development programs and the launch of new products, working capital requirements, and other strategic initiatives. Recently, we have met these cash requirements through cash, working capital management, and sales of products and services. In the past, we have also received proceeds from certain private placements and public offerings of our securities. For the nine months ended January 31, 2024, the Company had a net loss of approximately $7.2 million and cash used in operations of approximately $4.3 million. As of January 31, 2024, the Company had an accumulated deficit of approximately $84.5 million and cash on hand of approximately $4.5 million. We believe that our cash on hand, together with expected cash flows from operations to be provided for during fiscal 2025, are adequate to fund operations through at least 12 months from the filing of this Report. However, should our revenue expectations not materialize, we believe we have cost reduction strategies that could be implemented without disrupting the business or restructuring the Company. Should the Company be required to raise additional capital, there can be no assurance that management would be successful in raising such capital on terms acceptable to us, if at all.

Oncology Services Revenue

Oncology services revenue, which is primarily derived from pharmacology studies, was $12.0 million and $12.8 million for the three months ended January 31, 2024 and 2023, respectively, a decrease of $0.8 million or 5.9%. Oncology services revenue was $36.2 million and $40.8 million for the nine months ended January 31, 2024 and 2023, respectively, a decrease of

20

$4.6 million or 11.4%. The decrease in revenue resulted from an increase in study cancellations during fiscal year 2023, thereby reducing our net bookings and available convertible revenue in the current year.

Cost of Oncology Services

Cost of oncology services for the three months ended January 31, 2024 and 2023 were $7.8 million and $7.7 million, respectively, an increase of $150,000 or 1.9%. Cost of oncology services for the nine months ended January 31, 2024 and 2023 were $22.2 million and $22.2 million, respectively, a slight decrease of $43,000 or 0.2%. The net increase in cost of oncology services for the three months ended January 31, 2024 was primarily from an increase in compensation expense and mouse costs. For the three months ended January 31, 2024 and 2023, margins were 34.7% and 39.7%, respectively. For the nine months ended January 2024 and 2023, margins were 38.7% and 45.6%, respectively. The lower margin for both the three months and nine months ended January 31, 2024 resulted primarily from a decline in top line revenue against a generally unchanged cost base.

 Research and Development

Research and development expenses for the three months ended January 31, 2024 and 2023 were $2.2 million and $3.2 million, respectively, a decrease of approximately $1.0 million or 31.7%. Research and development expenses for the nine months ended January 2024 and 2023 were $7.5 million and $8.7 million, respectively, a decrease of approximately $1.2 million or 13.8%. The decrease in both the three and nine month periods was primarily due to a reduction in investment related to our target discovery program.

Sales and Marketing

Sales and marketing expenses for the three months ended January 31, 2024 and 2023 were $1.8 million and $1.8 million, respectively, a slight increase of $36,000 or 2.0%. Sales and marketing expenses for the nine months ended January 2024 and 2023 were $5.3 million and $5.2 million, respectively, an increase of $135,000 or 2.6%. Sales and marketing expenses are primarily comprised of compensation expenses to support business development.

General and Administrative

General and administrative expenses for the three months ended January 31, 2024 and 2023 were $2.8 million and $2.6 million, respectively, an increase of $195,000, or 7.6%. General and administrative expenses for the nine months ended January 31, 2024 and 2023 were $8.3 million and $7.5 million, respectively, an increase of $811,000, or 10.8%. General and administrative expenses are primarily comprised of compensation, insurance, professional fees, IT and depreciation and amortization expenses. The increase for the nine months ended January 31, 2024 was primarily from compensation and recruiting expenses and an increase in allowances for credit losses and bad debt reserves.

Cash Flows

The following discussion relates to the major components of our cash flows:

Cash Flows from Operating Activities

For the nine months ended January 31, 2024, net cash used in operating activities was $4.3 million. The cash used in operating activities was primarily due to the loss for the period resulting from lower revenue.

Cash Flows from Investing Activities

Net cash used in investing activities was $947,000 and $2.1 million for the nine months ended January 31, 2024 and 2023, respectively. The cash used in investing activities was for the investment in additional lab and computer equipment.

Cash Flows from Financing Activities

Net cash used in financing activities was $382,000 for the nine months ended January 31, 2024. The cash used was for the Company's stock repurchase program, offset by cash received from stock option exercises.

Factors That May Adversely Affect our Results of Operations

Our results of operations may be adversely affected by various factors that could cause economic uncertainty and volatility in the financial markets, many of which are beyond our control. Our business could be impacted by, among other things, downturns in the financial markets or in economic conditions, increases in oil prices, inflation, increases in interest rates, supply chain disruptions, declines in consumer confidence and spending, the ongoing effects of the COVID-19 pandemic, including resurgences and the emergence of new variants, and geopolitical instability, such as the military conflicts in Ukraine and the Middle East. We cannot at this time fully predict the likelihood of one or more of the above events, their duration, or magnitude or the extent to which they may negatively impact our business.

Critical Accounting Estimates and Policies

The preparation of these condensed consolidated financial statements in conformity with GAAP in the United States requires management to apply methodologies and make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates of the Company include, among other things, accounts receivable realization, revenue recognition (replacement of licensed tumors), valuation allowance for deferred tax assets, valuation of goodwill, and stock-based compensation and warrant assumptions. Actual results could differ from those estimates. The Company’s critical accounting policies are summarized in our 2023 Annual Report.

Off-Balance Sheet Financing

We have no off-balance sheet debt or similar obligations.  We have no transactions or obligations with related parties that are not disclosed, consolidated into or reflected in our reported results of operations or financial position.  We do not guarantee any third-party debt.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are a smaller reporting companies company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this Item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

It is management’s responsibility to establish and maintain “disclosure controls and procedures” as such term is defined in Rule 13a-15(e) under the Exchange Act. Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer have reviewed and evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Report. In designing and evaluating our disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily is required to apply its judgment in evaluating the relationship between the benefit of desired controls and procedures and the cost of implementing new controls and procedures.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Our management has assessed the effectiveness of our internal control over financial reporting as of January 31, 2024. Based on that assessment, our management, including our Chief Executive Officer and our Chief Financial Officer, have concluded that our disclosure controls and procedures were effective as of January 31, 2024 at the reasonable assurance level in ensuring that information required to be disclosed in the reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure. Further, management concluded that our consolidated financial statements in this Report present fairly, in all material respects, the Company’s financial position, results of operations and cash flows as of the dates, and for the periods presented, in conformity with U.S. GAAP.

Changes in Internal Control Over Financial Reporting

22

There have been no changes in our internal control over financial reporting in connection with the evaluation required by Rule 13a-15(d) of the Exchange Act that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

23

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

Item 1A. Risk Factors

As a smaller reporting company under Rule 12-2 of the Exchange Act, we are not required to include risk factors in this Report. However, as of the date of this Report, there have been no material changes with respect to those risk factors previously disclosed in our 2023 Annual Report. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risks could arise that may also affect our business. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

Organization, Use of Estimates and Basis of Presentation

Champions Oncology, Inc. (the "Company") is a technology-enabled research organization engaged in creating technology solutions to be utilized in drug discovery and development. The Company's research center operates in both regulatory and non-regulatory environments and consists of a comprehensive set of computational and experimental research platforms. Its pharmacology, biomarker, and data platforms are designed to facilitate drug discovery and development at lower costs and increased speeds.

The Company has four operating subsidiaries: Champions Oncology (Israel), Limited, Champions Biotechnology U.K., Limited, Champions Oncology, S.R.L. (Italy), and Corellia A.I.. For the three and nine months ended January 31, 2024 and 2023, there were no revenues earned by these subsidiaries.

The Company’s functional currency for its foreign subsidiaries is the U.S. dollar. Transaction gains and losses are recognized in earnings. The Company is subject to foreign exchange rate fluctuations in connection with the Company’s international operations.

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. Intercompany transactions and accounts have been eliminated. Certain information related to the Company’s organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, or GAAP, has been condensed or omitted. The April 30, 2023 condensed consolidated balance sheet in the accompanying interim condensed consolidated financial statements was derived from audited consolidated financial statements. The accounting policies followed in the preparation of these unaudited condensed consolidated financial statements are consistent with those followed in the Company’s annual consolidated financial statements for the fiscal year ended April 30, 2023, as filed in the Company's Annual Report on Form 10-K with the SEC on July 24, 2023 (the "Annual Report"). In the opinion of management, these unaudited condensed consolidated financial statements contain all material adjustments necessary to fairly state our financial position, results of operations and cash flows for the periods presented and the presentations and disclosures herein are adequate when read in conjunction with the Company’s 2023 Annual Report. The results of operations for the interim periods are not necessarily indicative of the results of operations for a full fiscal year.

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

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Cash and Cash Equivalents

The Company considers only those investments which are highly liquid, readily convertible to cash, and with original maturities of three months or less to be cash equivalents. As of January 31, 2024 the Company had cash equivalents of approximately $2.9 million and, as of April 30, 2023, the Company had no cash equivalents.

The Company is subject to a concentration of credit risk in the form of its cash deposits held at multiple banking institutions. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. As of January 31, 2024 and April 30, 2023, the Company had approximately $3.3 million and $8.7 million in excess of the FDIC insured limit, respectively.

Liquidity

The Company's liquidity needs have typically arisen from the funding of our research and development programs and the launch of new products, working capital requirements, and other strategic initiatives. Recently, the Company has met these cash requirements through cash on hand, working capital management, and sales of products and services. In the past, the Company has also received proceeds from certain private placements and public offerings of its securities. For the nine months ended January 31, 2024, the Company had a net loss of approximately $7.2 million and cash used in operations of approximately $4.3 million. As of January 31, 2024, the Company had an accumulated deficit of approximately $84.5 million and cash on hand of approximately $4.5 million. The Company believes that cash on hand, together with expected cash to be provided from operations during fiscal year 2025, are adequate to fund operations through at least 12 months from the filing of this Quarterly Report on Form 10-Q (this "Report"). However, should the Company's revenue expectations not materialize, the Company believes it has cost reduction strategies that could be implemented without disrupting the business or restructuring the Company. Should the Company be required to raise additional capital, there can be no assurance that management would be successful in raising such capital on terms acceptable to us, if at all.

Fair Value

The carrying value of cash, accounts receivable, prepaid expenses, and other current assets, accounts payable, and accrued liabilities approximate their fair value based on the liquidity or the short-term maturities of these instruments. The fair value hierarchy promulgated by GAAP consists of three levels:

•Level one — Quoted market prices in active markets for identical assets or liabilities;

•Level two — Inputs other than level one inputs that are either directly or indirectly observable; and

•Level three — Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use.

Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter. As of January 31, 2024 the Company had assets measured at fair value on a recurring and/or non-recurring basis as follows:

(in 000s)	January 31, 2024
	Level 1		Level 2		Level 3
Cash Equivalents:
Money market fund	2,854		—		—
Total	$	2,854	$	—	$	—

As of January 31, 2024, the Company had no liabilities measured at fair value on a recurring and/or non-recurring basis. As of April 30, 2023, the Company had no assets or liabilities measured at fair value on a recurring and/or non-recurring basis.

Earnings Per Share

Basic net income or loss per share is computed by dividing the net income or loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing the net income for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s common stock options.

As of January 31, 2024 and 2023, all of the Company's potential common stock is considered anti-dilutive.

The following table reflects the total potential share-based instruments outstanding at January 31, 2024 and 2023 including those that could have an effect on the future computation of dilution per common share, had their effect not been anti-dilutive due to the Company's net losses in the related periods:

	January 31,
	2024	2023
Total common stock equivalents	1,903,747	1,779,167

Income Taxes

    Deferred income taxes have been provided to show the effect of temporary differences between the recognition of expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. In assessing the realizability of deferred tax assets, the Company assesses the likelihood that deferred tax assets will be recovered through tax planning strategies or from future taxable income, and to the extent that recovery is not likely or there is insufficient earnings history, a valuation allowance is established. The Company's ability to utilize net operating losses (“NOL”) carryforwards to offset future taxable income would be limited if the Company had undergone or were to undergo an “ownership change” within the meaning of Section 382 of the Internal Revenue Code (the “IRC”). The Company adjusts the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized. Changes in valuation allowances from period to period are included in the tax provision in the period of change. As of January 31, 2024 and April 30, 2023, the Company provided a valuation allowance for all net deferred tax assets as it is more likely than not that the assets will not be recovered based on an insufficient history of earnings.

The Company reflects tax benefits only if it is more likely than not that the Company will be able to sustain the tax position, based on its technical merits.  If a tax benefit meets this criterion, it is measured and recognized based on the largest amount of benefit that is cumulatively greater than 50% likely to be realized.  The Company recorded $181,000 of liabilities related to uncertain tax positions relative to one of its foreign operations as of January 31, 2024 and April 30, 2023.

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company did not recognize interest or penalties on its consolidated statements of operations during the three and nine-month periods ended January 31, 2024 and 2023. The Company does not anticipate unrecognized tax benefits will be recorded during the next 12 months.

The provision for income taxes for the three months ended January 31, 2024 and 2023 was $11,000 and $17,000, respectively. The provision for income taxes for the nine months ended January 31, 2024 and 2023 was $49,000 and $48,000, respectively. The provision is mainly attributable to taxable income earned in Israel and/or Italy relating to transfer pricing.     

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") 606 ("ASC 606"), Revenue from Contracts with Customers. Under this standard, companies recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services.

All revenue is generated from contracts with customers. The Company's arrangements are service type contracts that mainly have a duration of less than a year. The Company recognizes revenue when control of these services is transferred to the customer in an amount, referred to as the transaction price, that reflects the consideration to which the Company is expected to be entitled in exchange for those services. The Company determines revenue recognition utilizing the following five steps: (1)

identification of the contract with a customer, (2) identification of the performance obligations in the contract (promised goods or services that are distinct), (3) determination of the transaction price, (4) allocation of the transaction price to the performance obligations, and (5) recognition of revenue when, or as, the Company transfers control of the product or service for each performance obligation. The Company records revenues net of any tax assessments by governmental authorities, such as value added taxes, that are imposed on and concurrent with specific revenue generating transactions.

The majority of the Company's revenue arrangements are service contracts that are completed within a year or less. There are a few contracts that range in duration between 1 and 3 years. Substantially all of the Company's performance obligations, and associated revenue, are transferred to the customer over time. Most of the Company's contracts can be terminated by the customer without cause. In the event of termination, the Company's contracts provide that the customer pay the Company for services rendered through the termination date. The Company generally receives compensation based on a predetermined invoicing schedule relating to specific milestones for that contract.

Amendments to contracts are common. The Company evaluates each amendment which meets the criteria of a contract modification under ASC 606. Each modification is further evaluated to determine whether the contract modification should be accounted for as a separate contract or as a continuation of the original agreement.

The Company accounts for amendments as a separate contract as they meet the criteria under ASC 606-10-25-12.

Pharmacology Study and Other Services

The Company generally enters into contracts with customers to provide oncology services with payments based on fixed-fee arrangements. At contract inception, the Company assesses the services promised in the contracts with customers to identify the performance obligations in the arrangement. The Company's fixed-fee arrangements for oncology services are considered a single performance obligation because the Company provides a highly-integrated service.

The Company recognizes revenue over time using a progress-based input method since there is no single output measure that would fairly depict the transfer of control over the life of the performance obligation. Revenue is recognized for the single performance obligation over time due to the Company's right to payment for work performed to date and the performance does not create an asset with an alternative use. The Company recognizes revenue as portions of the overall performance obligation are completed as this best depicts the progress of the performance obligation.

Incremental Costs of Obtaining a Contract (Sales Commissions)

Under ASC 606, the costs of obtaining a contract can be expensed immediately, rather than capitalized and amortized, if the amortization period is one year or shorter. Sales commissions for the Company represent contract costs with a term of one year or less. Therefore, under ASC 606, the Company elected the practical expedient to expense these costs as incurred.

Variable Consideration

In some cases, contracts provide for variable consideration that is contingent upon the occurrence of uncertain future events, such as the success of the initial performance obligation. Variable consideration is estimated at the expected value or at the most likely amount depending on the type of consideration. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The estimate of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.

Trade Receivables, Unbilled Services and Deferred Revenue

In general, billings and payments are established by contractual provisions including predetermined payment schedules, which may or may not correspond to the timing of the transfer of control of the Company's services under the contract. In general, the Company's intention in its invoicing (payment terms) is to maintain cash neutrality over the life of the contract. Upfront payments, when they occur, are intended to cover certain expenses the Company incurs at the beginning of the contract. Neither the Company nor its customers view such upfront payments and contracted payment schedules as a means of financing. Unbilled services primarily arise when the revenue recognized exceeds the amount billed to the customer. Such situations occur due to divergences between revenue recognition and the invoicing milestones which are based on predetermined payment terms.

Deferred revenue consists of unearned payments received in excess of revenue recognized. As the contracted services are subsequently performed and the associated revenue is recognized, the deferred revenue balance is reduced by the amount of the revenue recognized during the period. Deferred revenue is classified as a current liability on the condensed consolidated balance sheet as the Company expects to recognize the associated revenue in less than one year.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, “Financial Instruments—Credit Losses” (Topic 326). This ASU represents a significant change in the current accounting model by requiring immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred, which delayed recognition of expected losses that might not yet have met the threshold of being probable. The Company adopted ASU 2016-03 on April 1, 2023 and the adoption did not have any material effect on our condensed consolidated financial statements and related disclosures.

Contract Balances

Contract assets include unbilled amounts typically resulting from revenue recognized in excess of the amounts billed to the customer for which the right to payment is subject to factors other than the passage of time. These amounts may not exceed their net realizable value. Contract assets are classified as current and included in accounts receivable. Contract liabilities consist of customer payments received in advance of performance and billings in excess of revenue recognized, net of revenue recognized from the balance at the beginning of the period and included in deferred revenue. Contract assets and liabilities are presented on the balance sheet on a net contract-by-contract basis at the end of each reporting period.

Property and Equipment

Property and Equipment

Property and equipment is recorded at cost and primarily consists of laboratory equipment, computer equipment and software, capitalized software development costs, and furniture and fixtures. Depreciation and amortization is calculated on a straight-line basis over the estimated useful lives of the various assets ranging from three to nine years. Property and equipment consisted of the following (table in thousands):

	January 31, 2024		April 30, 2023
Furniture and fixtures	$	246	$	246
Computer equipment and software	2,152		2,102

Less: Accumulated depreciation and amortization	(9,961)		(8,630)
Property and equipment, net	$	6,533	$	7,186

Depreciation and amortization expense was $481,000 and $575,000 for the three months ended January 31, 2024 and 2023, respectively. Depreciation and amortization expense was $1.4 million and $1.7 million for the nine months ended January 31, 2024 and 2023, respectively. Depreciation and amortization expense, excluding expense recorded under finance leases, was $445,000 and $540,000 for the three months ended January 31, 2024 and 2023, respectively. Depreciation and amortization expense, excluding expense recorded under finance leases, was $1.3 million and $1.6 million for the nine months ended January 31, 2024 and 2023, respectively.

As of January 31, 2024 and April 30, 2023, property, plant and equipment included gross assets held under finance leases of $1.0 million. Related depreciation expense was approximately $36,000 and $35,000 for the three months ended January 31, 2024 and 2023, respectively, and $108,000 and $99,000 for the nine months ended January 31, 2024 and 2023, respectively.

During the nine months ended January 31, 2024, the Company disposed of two assets and recognized a loss on disposal of equipment of $81,000 within other income (loss) as presented in the condensed consolidated statement of operations. The first asset, laboratory equipment, was acquired for $128,000 and had accumulated depreciation of $62,000, resulting in a loss of $66,000 upon disposal. The second asset, acquired software, was purchased for $33,000 and had accumulated amortization of $18,000, resulting in a loss of $15,000 upon disposal.

Capitalized Software Development Costs Under a Hosting Arrangement

The Company accounts for the cost of computer software obtained or developed for internal use as well as the software development and implementation costs associated with a hosting arrangement ("internal-use software") that is a service contract

in accordance and with ASC 350, Intangibles - Goodwill and Other ("ASC-350"). We capitalize certain costs in the development of our internal-use software when the preliminary project stage is completed and it is probable that the project itself will be completed and the software will perform as intended. These capitalized costs include personnel and related expenses for employees and costs of third-party consultants who are directly associated with and who devote time to these internal-use software projects. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Costs incurred for significant upgrades, increased functionality, and enhancements to the Company's internal-use software solutions are also capitalized. Costs incurred for training, maintenance, and minor modifications are expensed as incurred. Capitalized software development costs are amortized using the straight-line method over an estimated useful economic life of three years.

The Company has capitalized development and implementation costs in accordance with accounting guidance for its Lumin platform. Lumin is the Company's oncology data-driven software program and data tool which operates as SaaS. These capitalized costs represent salaries, including direct payroll-related costs, certain software development consultant expenses and molecular sequencing programming costs incurred in the engineering and coding of the software development. Total capitalized gross asset costs for the Lumin platform that was launched and placed into service were $1.9 million. During the fourth quarter of fiscal year 2023, an impairment loss was recognized equal to the amount by which the carrying amount exceeded the future net revenues, or, its net book value at April 30, 2023 of $807,000. Amortization expense related to this asset was $0 and $157,000 for the three months ended January 31, 2024 and 2023, respectively, and $0 and $471,000 for the nine months ended January 31, 2024 and 2023, respectively.

Finance Lease

During fiscal year 2023, the Company recognized a finance lease for laboratory equipment. This equipment was obtained as the result of a laboratory supplies purchase commitment with costs of approximately $368,000 at inception through June 2027. Cash payments for this lease are in the form of consideration for purchasing lab supplies under a purchase commitment agreement. The present value of the minimum future obligations of $368,000 was calculated based on an interest rate of 3.5%. Depreciation and amortization expense related to this finance lease was $17,800 and $17,100 for the three months ended January 31, 2024 and 2023, respectively, and $52,800 and $45,100 for the nine months ended January 31, 2024 and 2023, respectively.

During fiscal year 2022, the Company recognized a finance lease for laboratory equipment. This equipment was obtained as the result of a laboratory supplies purchase commitment with costs of approximately $370,000 at inception through December 2025. Cash payments for this lease are in the form of consideration for purchasing lab supplies under a purchase commitment agreement. At the commencement of the commitment, the present value of the minimum future obligations of $370,000 was calculated based on an interest rate of 3.25%. Depreciation and amortization expense related to this finance lease was $18,700 and $18,000 for the three months ended January 31, 2024 and 2023, respectively, and $55,600 and $54,000 for the nine months ended January 31, 2024 and 2023, respectively.

The liabilities related to these finance leases are classified under other current liability and other non-current liabilities on the Company's balance sheet. The weighted average remaining lease term of these leases is 2.83 years.

The Company has in place a 2021 Equity Incentive Plan and 2010 Equity Incentive Plan (collectively, the "Plans"). In general, these Plans provide for stock-based compensation to the Company’s employees, directors and non-employees. The Plans also provide for limits on the aggregate number of shares that may be granted, the term of grants and the strike price of option awards.

2021 Equity Incentive Plan

As part of the 2021 Annual Shareholders Meeting, shareholders approved the adoption of the 2021 Equity Incentive Plan (“2021 Equity Plan”). The purpose of the 2021 Equity Plan is to grant (i) Non-statutory Stock Options; (ii) Incentive Stock Options; (iii) Restricted Stock Awards; and/or (iv) Stock Appreciation Rights (collectively, stock-based compensation) to its employees, directors and non-employees. Total stock awards under the 2021 Equity Plan shall not exceed 2 million shares of common stock. Options and Stock Appreciation Rights expire no later than ten years from the date of grant and the awards vest as determined by the Company's Board of Directors. Options and Stock Appreciation Rights have a strike price not less than 100% of the fair market value of the common stock subject to the option or right at the date of grant. As of January 31, 2024, approximately 1.3 million shares were available for issue under this plan.

2010 Equity Incentive Plan

On February 18, 2011, shareholders owning a majority of the issued and outstanding shares of the Company executed a written consent approving the 2010 Equity Incentive Plan (“2010 Equity Plan”). The purpose of the 2010 Equity Plan is to grant (i) Non-statutory Stock Options; (ii) Restricted Stock Awards; and (iii) Stock Appreciation Rights (collectively, stock-based compensation) to its employees, directors and non-employees. Total stock awards under the 2010 Equity Plan shall not exceed 30 million shares of common stock. Options and Stock Appreciation Rights expire no later than ten years from the date of grant and the awards vest as determined by the Board of Directors. Options and Stock Appreciation Rights have a strike price not less than 100% of the fair market value of the common stock subject to the option or right at the date of grant. After February 2021, no more shares were available to be issued from this plan.

Stock Option Grants

Black-Scholes assumptions used to calculate the fair value of options granted during the three and nine months ended January 31, 2024 and 2023 were as follows:

	Three Months Ended January 31,		Nine Months Ended January 31,

Volatility	63.41%	61.88%	62.83% - 63.41%	61.88% - 62.58%
Dividend yield	—%	—%	—%	—%

The weighted average fair value of stock options granted during the three months ended January 31, 2024 and 2023 was $3.41 and $4.20, respectively. The weighted average fair value of stock options granted during the nine months ended January 31, 2024 and 2023 was $3.77 and $4.33, respectively.

The Company’s stock options activity for the nine months ended January 31, 2024 was as follows:

Share Repurchase Program

On March 29, 2023, the Board of Directors approved a share repurchase program authorizing the Company to purchase up to an aggregate of $5.0 million of the Company’s common stock. The share repurchase program is designed in accordance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The shares may be purchased from time to time in the open market, as permitted under applicable rules and regulations, at prevailing market prices. The timing and amount of repurchases will depend on market conditions, share price, applicable legal requirements and other factors. The program does not obligate the Company to acquire a minimum number of shares. As of January 31, 2024, the Company had purchased approximately 120,300 shares of its common stock, at an average price of $5.73 per share, totaling approximately $708,000 and leaving an available balance of approximately $4.3 million authorized by the Board for use in the program as of that date.

Leases [Abstract]

Leases

Leases

The Company accounts for its leases under FASB ASC Topic 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use ("ROU") asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease, if applicable, or the Company’s incremental borrowing rate. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term.

Operating Leases

The Company currently leases certain office equipment and its office and laboratory facilities under non-cancelable operating leases. Rent expense for operating leases is recognized on a straight-line basis over the lease term from the lease commencement date through the scheduled expiration date. Rent expense totaled $454,000 and $475,000 for the three months ended January 31, 2024 and 2023, respectively. Rent expense totaled $1.4 million for both the nine months ended January 31, 2024 and 2023. The Company considers its facilities adequate for its current operational needs.

The Company leases the following facilities:

•One University Plaza, Suite 307, Hackensack, New Jersey 07601, which, since November 2011, serves as the Company’s corporate headquarters. The lease expires in November 2026. The Company recognized $19,000 and $20,000 of rent expense relative to this lease for the three months ended January 31, 2024 and 2023, respectively.The Company recognized $57,000 and $62,000 of rent expense relative to this lease for the nine months ended January 31, 2024 and 2023, respectively.

•1330 Piccard Drive Suite 025, Rockville, MD 20850, which consists of laboratory and office space where the Company conducts operations related to its primary service offerings. The Company executed the original lease in January 2017. The lease was amended to expand the premises and extend the expiration date in March 2020 and again in December 2020. The operating commencement date was August 11, 2017. This lease expires in February 2029. The Company recognized $422,000 of rent expense relative to this lease for both the three months ended January 31, 2024 and 2023, and $1.3 million of rent expense relative to this lease for both the nine months ended January 31, 2024 and 2023.

•VIA LEONE XIII, 14, Milan, Italy, which consists of laboratory and office space where the Company conducts operations related to its flow cytometry service offerings. The Company executed separate leases for its laboratory space and office space during fiscal 2022. During fiscal 2023, the Company executed a new lease to consolidate its office and laboratory space at a new nearby location in Italy. The lease expires October 31, 2028 and it replaces the previous two leases, which were terminated during fiscal year 2023. The Company recognized $13,000 and $34,000 of rent expense relative to these leases for the three months ended January 31, 2024 and 2023, respectively, and $38,000 and $81,000 for the nine months ended January 31, 2024 and 2023, respectively.

Commitments and Contingencies

Legal Matters

The Company is not currently party to any legal matters to its knowledge. The Company is not aware of any other matters that would have a material impact on the Company’s financial position or results of operations.

Registration Payment Arrangements

The Company has entered into an Amended and Restated Registration Rights Agreement in connection with the March 2015 private placement. This Amended and Restated Registration Rights Agreement contains provisions that may call for the Company to pay penalties in certain circumstances. This registration payment arrangement primarily relates to the Company’s ability to file a registration statement within a particular time period, have a registration statement declared effective within a particular time period and to maintain the effectiveness of the registration statement for a particular time period. The Company has not accrued any liquidated damages associated with the Amended and Restated Registration Right Agreement as the Company has filed the required registration statement and anticipates continued compliance with the agreement.

Royalties

The Company contracts with third-party vendors to license tumor samples for development into Patient Derived Xenograft (PDX) models and use in our pharmacology TOS business. These types of arrangements have an upfront fee ranging from nil to $30,000 per tumor sample depending on the successful growth of the tumor model and ability to develop them into a sellable product. The upfront costs are expensed as incurred. In addition, under certain agreements, for a limited period of time, the Company is subject to royalty payments if the licensed tumor models are used for sale in our TOS business, ranging from 2% to 20% of the contract price after recouping certain initiation costs. Some of these arrangements also set forth an annual minimum royalty due regardless of tumor models used for sale. For the three months ended January 31, 2024 and 2023, we have recognized approximately $114,000 and $21,000, respectively, in expense related to these royalty arrangements. For the nine months ended January 31, 2024 and 2023, we have recognized approximately $240,000 and $129,000, respectively, in expense related to these royalty arrangements.

Significant Accounting Policies (Policies)

9 Months Ended

Jan. 31, 2024

Accounting Policies [Abstract]

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers only those investments which are highly liquid, readily convertible to cash, and with original maturities of three months or less to be cash equivalents.

Fair Value

Fair Value

The carrying value of cash, accounts receivable, prepaid expenses, and other current assets, accounts payable, and accrued liabilities approximate their fair value based on the liquidity or the short-term maturities of these instruments. The fair value hierarchy promulgated by GAAP consists of three levels:

•Level one — Quoted market prices in active markets for identical assets or liabilities;

•Level two — Inputs other than level one inputs that are either directly or indirectly observable; and

•Level three — Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use.

Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter.

Earnings Per Share

Earnings Per Share

Basic net income or loss per share is computed by dividing the net income or loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing the net income for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s common stock options.

Income Taxes

Income Taxes

    Deferred income taxes have been provided to show the effect of temporary differences between the recognition of expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. In assessing the realizability of deferred tax assets, the Company assesses the likelihood that deferred tax assets will be recovered through tax planning strategies or from future taxable income, and to the extent that recovery is not likely or there is insufficient earnings history, a valuation allowance is established. The Company's ability to utilize net operating losses (“NOL”) carryforwards to offset future taxable income would be limited if the Company had undergone or were to undergo an “ownership change” within the meaning of Section 382 of the Internal Revenue Code (the “IRC”). The Company adjusts the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized. Changes in valuation allowances from period to period are included in the tax provision in the period of change. As of January 31, 2024 and April 30, 2023, the Company provided a valuation allowance for all net deferred tax assets as it is more likely than not that the assets will not be recovered based on an insufficient history of earnings.

The Company reflects tax benefits only if it is more likely than not that the Company will be able to sustain the tax position, based on its technical merits.  If a tax benefit meets this criterion, it is measured and recognized based on the largest amount of benefit that is cumulatively greater than 50% likely to be realized.The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense.

Revenue Recognition

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") 606 ("ASC 606"), Revenue from Contracts with Customers. Under this standard, companies recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services.

All revenue is generated from contracts with customers. The Company's arrangements are service type contracts that mainly have a duration of less than a year. The Company recognizes revenue when control of these services is transferred to the customer in an amount, referred to as the transaction price, that reflects the consideration to which the Company is expected to be entitled in exchange for those services. The Company determines revenue recognition utilizing the following five steps: (1)

identification of the contract with a customer, (2) identification of the performance obligations in the contract (promised goods or services that are distinct), (3) determination of the transaction price, (4) allocation of the transaction price to the performance obligations, and (5) recognition of revenue when, or as, the Company transfers control of the product or service for each performance obligation. The Company records revenues net of any tax assessments by governmental authorities, such as value added taxes, that are imposed on and concurrent with specific revenue generating transactions.

The majority of the Company's revenue arrangements are service contracts that are completed within a year or less. There are a few contracts that range in duration between 1 and 3 years. Substantially all of the Company's performance obligations, and associated revenue, are transferred to the customer over time. Most of the Company's contracts can be terminated by the customer without cause. In the event of termination, the Company's contracts provide that the customer pay the Company for services rendered through the termination date. The Company generally receives compensation based on a predetermined invoicing schedule relating to specific milestones for that contract.

Amendments to contracts are common. The Company evaluates each amendment which meets the criteria of a contract modification under ASC 606. Each modification is further evaluated to determine whether the contract modification should be accounted for as a separate contract or as a continuation of the original agreement.

The Company accounts for amendments as a separate contract as they meet the criteria under ASC 606-10-25-12.

Pharmacology Study and Other Services

The Company generally enters into contracts with customers to provide oncology services with payments based on fixed-fee arrangements. At contract inception, the Company assesses the services promised in the contracts with customers to identify the performance obligations in the arrangement. The Company's fixed-fee arrangements for oncology services are considered a single performance obligation because the Company provides a highly-integrated service.

The Company recognizes revenue over time using a progress-based input method since there is no single output measure that would fairly depict the transfer of control over the life of the performance obligation. Revenue is recognized for the single performance obligation over time due to the Company's right to payment for work performed to date and the performance does not create an asset with an alternative use. The Company recognizes revenue as portions of the overall performance obligation are completed as this best depicts the progress of the performance obligation.

Incremental Costs of Obtaining a Contract (Sales Commissions)

Under ASC 606, the costs of obtaining a contract can be expensed immediately, rather than capitalized and amortized, if the amortization period is one year or shorter. Sales commissions for the Company represent contract costs with a term of one year or less. Therefore, under ASC 606, the Company elected the practical expedient to expense these costs as incurred.

Variable Consideration

In some cases, contracts provide for variable consideration that is contingent upon the occurrence of uncertain future events, such as the success of the initial performance obligation. Variable consideration is estimated at the expected value or at the most likely amount depending on the type of consideration. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The estimate of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.

Trade Receivables, Unbilled Services and Deferred Revenue

In general, billings and payments are established by contractual provisions including predetermined payment schedules, which may or may not correspond to the timing of the transfer of control of the Company's services under the contract. In general, the Company's intention in its invoicing (payment terms) is to maintain cash neutrality over the life of the contract. Upfront payments, when they occur, are intended to cover certain expenses the Company incurs at the beginning of the contract. Neither the Company nor its customers view such upfront payments and contracted payment schedules as a means of financing. Unbilled services primarily arise when the revenue recognized exceeds the amount billed to the customer. Such situations occur due to divergences between revenue recognition and the invoicing milestones which are based on predetermined payment terms.

Deferred revenue consists of unearned payments received in excess of revenue recognized. As the contracted services are subsequently performed and the associated revenue is recognized, the deferred revenue balance is reduced by the amount of the revenue recognized during the period. Deferred revenue is classified as a current liability on the condensed consolidated balance sheet as the Company expects to recognize the associated revenue in less than one year.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, “Financial Instruments—Credit Losses” (Topic 326). This ASU represents a significant change in the current accounting model by requiring immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred, which delayed recognition of expected losses that might not yet have met the threshold of being probable. The Company adopted ASU 2016-03 on April 1, 2023 and the adoption did not have any material effect on our condensed consolidated financial statements and related disclosures.

Leases

The Company accounts for its leases under FASB ASC Topic 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use ("ROU") asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease, if applicable, or the Company’s incremental borrowing rate. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term.
