PART I

Item 1. Business

Overview

We are a technology-enabled research organization engaged in creating technology solutions to be utilized in drug discovery and development. Our research center operates in both regulatory and non-regulatory environments and 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.

At the core of our research platforms is our unique, proprietary bank of Patient Derived Xenograft (PDX) models. This preeminent bank of PDX models is deployed into advanced in vivo and ex vivo pharmacology platforms, providing an enhanced level of insight into therapeutic programs. We currently have approximately 1,500 PDX Models in our TumorBank that we believe reflect the characteristics of patients who enroll in clinical trials (late stage, pretreated and metastatic). This characteristic of our TumorBank is an important differentiator to other established PDX banks. We implant and expand these tumors in mice, which allows for future studies and additional characterization of the tumor. Additional analytical and pharmacology experimental platforms are also available to augment the information gained from studies performed.

The PDX bank is highly characterized at the molecular, phenotypic and pharmacological levels, which provides a differentiated layer of data for our large oncology dataset (the "Datacenter"). The Datacenter combines our proprietary dataset with other large publicly available datasets. This dataset currently includes approximately 3,500 molecular datasets (genomics, transcriptomics, proteomics, phosphor-proteomics), approximately 3,000 clinical drug responses, approximately 3,500 in vivo drug responses, and the accompanying clinical information on the patients from which they were derived (pre and post tumor sample acquisition of drug treatments and responses, age, gender, ethnicity, tumor stage, tumor grade, location of tumor biopsy, histology, etc.) derived from our TumorBank. One unique feature of this proprietary dataset is the fact that it is derived from a living TumorBank. This allows us to continue characterizing the TumorBank over time and increase the depth of characterization of the accumulated data. The combination of the breadth and depth of the TumorBank, and associated characterization, drives the value of our Datacenter. The Datacenter also includes approximately 20,000 publicly available datasets including genomics, transcriptomics, proteomics, and functional genomics, and patient outcome. This Datacenter facilitates our computational approach to drug discovery and provides the foundation to our Software as a Service ("SaaS") offerings. Collectively, our computational and experimental research platforms enable a more rapid and precise approach to drug discovery and development.

Through our technology platforms, we have designed an ecosystem of business lines consisting of:

•The sale of research services utilizing our innovative research platforms to biopharmaceutical companies

•The sale of PDX model data and oncology research SaaS tools to cancer research scientists

•The discovery and development of novel oncology therapeutics

Translational Oncology Solutions (TOS) Business

Research Services

Our research services utilize our research center to assist pharmaceutical and biotechnology companies with their drug development process. 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. Our studies can be used to determine which types of cancer, if any, may be inhibited by a drug. The studies can also be used to identify specific sub-populations, often characterized by particular genetic mutations that are differentially sensitive or resistant to a drug or drug combination. 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.

Increasing the breadth of the TumorBank is an important strategic effort of the Company. We invest significant research and development resources to increase the number of PDX Models in our TumorBank and add unique and different sub-types of cancer that are not historically addressed. This effort also allows us to build highly valuable PDX models derived from patients with resistance to specific therapies or important molecular annotations. We also invest significant resources to increase the depth of characterization of the TumorBank. For each model, this characterization includes phenotypic analysis, molecular analyses, and pharmacologic analysis. This depth of characterization, in an individual tumor basis, is unique and not widely available.

We have performed studies for approximately 500 different pharmaceutical and biotechnology companies over the past ten years, have a high rate of repeat business, and contract with pharmaceutical and biotechnology companies across North America, Europe and Asia. Studies are performed in a preclinical non-regulatory environment, as well as a Good Clinical Regulatory Practice (GCLP) regulatory environment for clinical evaluation. Typical studies are in the $125,000 price range, with an increasing number of studies in the $250,000 to $500,000 range. Studies performed in a regulatory environment can be much larger than those performed within a non-regulatory environment. Revenue from this business has grown at an average annual growth rate of 12% since 2019 and represents the primary source of our current revenue stream.

Data Licenses

We offer access to certain PDX model data via licensing agreements. As our platform has been expanded over time with the collection of models and the enhancement of their characterization, we have developed a robust multi-omic dataset with substantial potential for both drug discovery and development. This dataset serves as a vital resource for both our pharmaceutical and biotechnology customer who gain access to model-specific data and further their research via licensed access.

Software As A Service (SaaS) Business

Our SaaS business is centered around our proprietary software platform and data tool, Lumin Bioinformatics ("Lumin"), which contains comprehensive information derived from our research services and clinical studies and is sold to customers on an annual subscription basis. The software was developed by a team that consisted of bioinformatics scientists and mathematicians as well as software engineers. Lumin leverages Champions’ large Datacenter coupled with analytics and artificial intelligence to provide a robust tool for computational cancer research. It is the combination of the Datacenter and the analytics that create the foundation for Lumin. 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.

Drug Discovery and Development Business

Our nascent 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 rapidly validate these targets for further drug development efforts. Our efforts center around three areas of focus:

1.Targeted therapy with drug conjugates

2.Immune oncology

3.Cell therapy

Our Drug Discovery and Development business is dependent on a dedicated research and development team, made up of computational and experimental scientists. Importantly, the scientific teams within our Drug Discovery and Development teams are appropriately segregated from our other businesses.

We have a rich 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.

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, licensing opportunities, or capital raises.

Our sales and marketing efforts are dependent on a dedicated sales force of approximately 45 professionals that sell our services directly to pharmaceutical and biotechnology companies. Our research services team is focused on identifying and selling studies to new customers as well as increasing our revenue from our existing customer base. We spend significant resources in informing our customers and reaching out to new contacts within companies that we currently serve. These efforts are aimed at moving our customers along the adoption curve for our research platforms, thereby increasing the number of studies and the average study size. Our success in these efforts is demonstrated by the growing number of customers who have continued to increase their annual spend on our services over the years.

For the fiscal year ended April 30, 2026, revenues from our products and services totaled approximately $59.4 million, an increase of approximately 4% from the previous year.

Our Current Strategy

Our strategy is to use our various platform technologies to drive multiple synergistic revenue streams. We continue to build upon this with investments in research and development. Our enterprise strategy consists of the following:

•Establish a global leadership position in oncology research

•A focus on bringing better drugs to patients faster

•Leading innovation in oncology research and development platforms

•Cultivating a solid reputation for the quality of data acquisition and interpretation

•Collaborations across the global biopharma landscape

•Profitable growth across all business lines

Our Growth and Expansion Strategy

Our strategy is to continue to use our various platform technologies to drive multiple synergistic revenue streams.

Our strategy for growth has multiple components:

•Growing our TumorBank: We grow our TumorBank in two ways. First, we leverage a medical affairs team that works with a well-established clinical network to facilitate access to patients diagnosed with prioritized tumor subtypes. Second, we maintain the ability to utilize our legacy Personalized Oncology Services business to establish novel PDX models from patients who use this service. The PDX models are then deeply characterized at the phenotypic, molecular, and pharmacologic levels. This data characterization is then added to our Datacenter.

•Adding new experimental technologies: The fields of oncology research and drug development are evolving rapidly. To keep up with new approaches, we continuously add new technologies to platform. We are currently investing in developing additional proprietary pharmacology platforms aimed at enhancing the scientific output and driving innovation in the oncology research sector. This includes expanding our capabilities to support the evaluation of

radiopharmaceutical therapies through our preclinical research platforms. We are also investing in the development of sophisticated analytical platforms which allow scientists to derive deeper insights when using our pharmacology platforms. Once these experimental technologies are established they are made available to our research and development and target discovery teams.

•Computational power: We have developed sophisticated and innovative computational approaches. We have also invested in the development of novel artificial intelligence, data structures, and analytics. Our goal is to leverage our unique Datacenter to establish elegant ways to better understand the molecular dynamics of cancer, and the development of novel therapeutics.

Competition

Champions currently competes in three different markets:

Research Services: Pharmaceutical companies rely on outsourcing preclinical studies to Clinical Research Organizations. Competition in this industry is intense and based significantly on scientific, technological, and market forces, which include the effectiveness of the technology and products and the ability to commercialize technological developments. The Company faces significant competition from other healthcare companies in the United States and abroad. The majority of these competitors are, and will be, substantially larger than the Company, and have substantially greater resources and operating histories. There can be no assurance that developments by other companies will not render our products or technologies obsolete or non-competitive or that we will be able to keep pace with the technological or product developments of our competitors. These companies, as well as academic institutions, governmental agencies, and private research organizations also compete with us in recruiting and retaining highly qualified scientific, technical and professional personnel and consultants.

SaaS: There are two important components of Lumin: the Datacenter and the Analytics. While we feel our Datacenter is unique, there are a large number of publicly available datasets that can be accessed free of charge for computational research. This publicly available data repertoire is constantly growing as academic labs publish results. We continue to find ways to differentiate our dataset, however there can be no assurance that developments by other companies or academic institutions in data curation will not render our Datacenter obsolete or non-competitive. The second component of Lumin is the data analytics. While there are a minimal number of software solutions that offer the degree of analytics available within Lumin, the know-how and workflows of these analytics are well established in bioinformatics labs across academia and the biopharmaceutical industry. As a result, the barrier to entry for developing a SaaS tool leveraging these analytics is relatively low.

Drug Discovery and Development: Our Drug Discovery and Development business places us in a good position of also competing against the same customers of our Research Services and/or SaaS businesses: the global biopharmaceutical industry. The global oncology drug market was estimated to exceed $286 billion in 2026 with continued projected growth. Competition in this industry is strong and based significantly on scientific and technological forces, which rely solely on the effectiveness of therapeutics designed to treat cancer. The Company faces significant competition from other biopharmaceutical companies in the United States and abroad. The competitors have a wide range of strategic and operational approaches. Our business strategy is to work with differentiated therapeutic targets and research areas. However, given the intense degree of privacy from our competitors, we cannot guarantee that others within the industry are not also working on these targets. Further, some competitors will operate with no laboratory or experimental operations, while others will have varying degrees of laboratory space and experimental capabilities. There can be no assurance that developments by other companies will not render experimental platforms obsolete or non-competitive or that we will be able to keep pace with the technological or product developments of our competitors. These companies, as well as academic institutions, governmental agencies, and private research organizations also compete with us in recruiting and retaining highly qualified scientific, technical and professional personnel and consultants.

Research and Development

For the fiscal years ended April 30, 2026 and 2025, we spent approximately $9.1 million and $6.8 million, respectively, to further develop our platforms. We continue to expand our TumorBank via the inclusion of tumor tissue and implanted models through research collaborations and relationships with hospitals and academic institutions. Our research and development efforts were focused on increasing our understanding of our TumorGraft models, their clinical predictability, improving growth and tumor take rates, and other biological and molecular characteristics of the models. We are investing in developing additional proprietary pharmacology platforms aimed at enhancing the scientific output and driving innovation in the oncology research sector.

We are also investing in the acquisition of sophisticated analytical platforms which allow scientists to derive deeper insights when using our pharmacology platforms.

Government Regulation

The research, development, and marketing of our products, the performance of our legacy Personalized Oncology Services (POS) testing services, and the operation of our facilities are generally subject to federal, state, local, or foreign legislation, including licensure of our laboratory located in Rockville, Maryland by the State of Maryland and compliance with federal, state, local or foreign legislation applicable to the use of live animals in scientific testing, research and education.

The U.S. Food and Drug Administration (the "FDA") has claimed regulatory authority over laboratory developed tests such as our legacy POS products, but has generally not exercised it. The FDA has announced regulatory and guidance initiatives that could increase federal regulation of our business. We are subject to federal and international regulations with regard to shipment of hazardous materials, including those issued by the Department of Transportation and the International Air Transit Authority. These regulations require interstate, intrastate, and foreign shipments to comply with applicable labeling, documentation, and training requirements.

Human Capital Resources

As of July 15, 2026, we had 214 full-time employees, including 103 with doctoral or other advanced degrees. Of our workforce, 149 employees are engaged in research and development and laboratory operations, 45 employees are engaged in sales and marketing, and 20 employees are engaged in finance, IT, and administration.

We believe that our future success will depend, in part, on our ability to continue to attract, hire, and retain qualified personnel. We continue to seek additions to our science and technical staff, although the competition for such personnel in the pharmaceutical and biotechnology industries is intense. Attracting, developing, and retaining skilled and experienced employees in our industry is crucial to our ability to compete effectively. Our ability to recruit and retain such employees depends on a number of factors, including our corporate culture and work environment, our corporate philosophy, internal talent development and career opportunities, and compensation and benefits.

None of our employees are represented by a labor union or covered by collective bargaining agreements. We have never experienced a work stoppage and believe our relationship with our employees is good.

Company History

We were incorporated as a merger and acquisition company under the laws of the State of Delaware on June 4, 1985, under the name “International Group, Inc.” In September 1985, the Company completed a public offering and shortly thereafter acquired the worldwide rights to the Champions sports theme restaurant concept and changed its name to “Champions Sports, Inc.” In 1997, the Company sold its Champions service mark and concept to Marriott International, Inc. and until 2005, was a consultant to Marriott International, Inc. and operated one Champions Sports Bar Restaurant. In January 2007, the Company changed its business direction to focus on biotechnology and subsequently changed its name to Champions Biotechnology, Inc. On May 18, 2007, the Company acquired Biomerk, Inc., at which time we began focusing on our current line of business. In April 2011, the Company changed its name to Champions Oncology, Inc. to reflect the Company's new strategic focus on developing advanced technologies to personalize the development and use of oncology drugs.

Item 1A. Risk Factors

You should carefully consider the risks described below together with all of the other information included in this Annual Report. The risks and uncertainties described below are not the only ones we face. Additional risks not presently known, or those we currently consider insignificant, may also impair our business operations in the future.

We historically incurred losses from operating activities, may require significant capital and may never achieve sustained profitability.

For the fiscal year ended April 30, 2026, the Company had a net loss of approximately $1.2 million, an accumulated deficit of approximately $81.1 million, and a cash balance of $4.9 million. The Company used cash in operations of approximately $4.5 million for the twelve months ending April 30, 2026. We believe that our cash on hand, together with expected cash flows from operations, are adequate to fund our operations through at least August 2027.

The amount of our income or losses and liquidity requirements may vary significantly from year-to-year and quarter-to-quarter and will depend on, among other factors:

•the cost of continuing to build out our TumorGraft bank;

•the cost and rate of progress toward growing our technology platforms;

•the cost and rate of progress toward building our business units;

•the cost of increasing our research and development;

•the cost of renting our laboratory and animal testing facilities and payment for associated services;

•the timing and cost of obtaining and maintaining any necessary regulatory approvals;

•the cost of expanding and building out our infrastructure; and

•the cost incurred in hiring and maintaining qualified personnel.

Currently, the Company derives revenue primarily from research services, while pursuing efforts to further develop our drug discovery business units.

To become sustainably profitable, the Company will need to generate revenues to offset our operating costs, including our research and development and general and administrative expenses. We may not achieve or sustain our revenue or profit objectives. If we incur losses in the future and/or we are unable to obtain sufficient capital either from operations or externals sources, ultimately, we may have to cease operations.

In order to grow revenues, we must invest capital to implement our sales and marketing efforts and to successfully develop our technology platforms. Our sales and marketing efforts may never generate significant increases in revenues or achieve profitability and it is possible that we will be required to raise additional capital to continue our operations. If we must devote a substantial amount of time to raising capital, it will delay our ability to achieve our business goals within the time frames that we now expect, which could increase the amount of capital we need. In addition, the amount of time expended by our management on fundraising distracts them from concentrating on our business affairs. If we require additional capital and are not successful in raising the needed capital, we may have to cease operations.

We may incur greater costs than anticipated, which could result in sustained losses.

We use reasonable efforts to assess and predict the expenses necessary to pursue our business strategies. However, implementing our business strategies may require more employees, capital equipment, supplies or other expenditure items than management has predicted. Similarly, the cost of compensating additional management, employees and consultants or other operating costs may be more than we estimate, which could result in ongoing and sustained losses.

We may not be able to implement our business strategies, which could impair our ability to continue operations.

Implementation of our business strategies will depend in large part on our ability to (i) attract and maintain a significant number of customers; (ii) effectively provide acceptable services to our customers; (iii) develop and license new products and technologies; (iv) maintain appropriate internal procedures, policies, and systems; (v) hire, train, and retain skilled employees and management; (vi) continue to operate despite increasing competition in our industry; and (vii) establish, develop and maintain our name recognition. Our inability to obtain or maintain any or all these factors could impair our ability to implement our business strategies successfully, which could have material adverse effects on our results of operations and financial condition.

Our laboratories are subject to regulation and licensure requirements, and the healthcare industry is highly regulated; we may face substantial penalties, and our business activities may be impacted, if we fail to comply.

Our research services are performed in laboratories that are subject to state regulation and licensure requirements. Such regulation and requirements are subject to change, and may result in additional costs or delays in providing our products to our customers. In addition, the healthcare industry in general is highly regulated in the United States at both the federal and state levels. We seek to conduct our business in compliance with all applicable laws, but many of the laws and regulations potentially applicable to us are vague or unclear. These laws and regulations may be interpreted or applied by an authority in a way that could require us to make changes in our business. We may not be able to obtain all regulatory approvals needed to operate our business or sell our products. If we fail to do so, we could be subject to civil and criminal penalties or fines or lose the authorizations necessary to operate our business, as well as incur additional liabilities from third parties. If any of these events happened, they could hurt our business and financial results.

If our laboratory facilities are damaged or destroyed, or we have a dispute with one of our landlords, our business would be negatively affected.

We currently utilize several office suites where our laboratories are located within one facility in Rockville, Maryland. If this facility was to be significantly damaged or destroyed, we could suffer a loss of our ongoing and future drug studies, as well as our TumorBank. In addition, we lease the laboratories from a third party. If we had a dispute with our landlord or otherwise could not utilize our space, it would take time to find and move to a new facility, which could negatively affect our results of operations.

Any health crisis impacting our colony of laboratory mice could have a negative impact on our business.

Our research services operations depend on having a colony of live mice available. If this population experienced a health crisis, such as a virus or other pathogen, such crisis would affect the success of our existing and future business, as we would have to rebuild the population and repeat current studies.

We have limited experience marketing and selling our products and may need to rely on third parties to successfully market and sell our products and generate revenues.

Currently, we rely on the internet, word of mouth, and a small sales force to market our services. We have to compete with other pharmaceutical, biotechnology and life science technology and service companies to recruit, hire, train, and retain marketing and sales personnel. However, there can be no assurance that we will be able to develop in-house sales, and as a result, we may not be able to generate product revenue.

We will continue to be dependent upon key employees.

Our success, currently, is dependent upon the efforts of several full-time key employees, the loss of the services of one or more of which would have a material adverse effect on our business and financial condition. We intend to continue to develop our management team and attract and retain qualified personnel in all functional areas to expand and grow our business. This may be difficult in the healthcare industry where competition for skilled personnel is intense.

Because our industry is very competitive and many of our competitors have substantially greater capital resources and more experience in research and development, we may not succeed in selling or increasing sales of our products and technologies.

We are engaged in a rapidly changing and highly competitive field. Potential competitors in the United States and abroad are numerous and include providers of clinical research services, most of which have substantially greater capital resources and more experience in research and development capabilities. Furthermore, new companies will likely enter our market from the United States and abroad, as scientific developments surrounding other pre-clinical and clinical services grow in the multibillion dollar oncology marketplace. Our competitors may succeed in selling their products to our pharmaceutical and biotech customers more effectively than we sell our products. In addition, academic institutions, hospitals, governmental agencies, and other public and private research organizations also may conduct similar research, seek patent protection, and may develop and commercially introduce competing products or technologies on their own or through joint ventures. If one or more of our competitors succeeds in developing similar technologies and products that are more effective or successful than any of those that we currently sell or will develop, our results of operations will be significantly adversely affected.

If we are unable to protect our intellectual property, we may not be able to compete as effectively.

It is important in the healthcare industry to obtain patent and trade secret protection for new technologies, products, and processes. Our success will depend, in part, upon our ability to obtain, enjoy, and enforce protection for any products we have, develop or acquire under United States and foreign patent laws and other intellectual property laws, preserve the confidentiality of our trade secrets, and operate without infringing the proprietary rights of third parties. Where appropriate, we will seek patent protection for certain aspects of our technology. However, while our TumorGraft Technology Platform is proprietary and requires significant know-how to both initiate and operate, it is not patented. It is, therefore, possible for competitors to develop other implantation procedures, or to discover the same procedures utilized by us, that could compete with us in our market.

It also is unclear whether efforts to secure our trade secrets will provide useful protection. While we will use reasonable efforts to protect our trade secrets, our employees or consultants may unintentionally or willfully disclose our proprietary information to competitors resulting in a loss of protection. Enforcing a claim that someone else illegally obtained and is using our trade secrets, like patent litigation, is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Finally, our competitors may independently develop equivalent knowledge, methods and know-how.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

We rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and other third parties. We also seek to enter into confidentiality and invention assignment agreements with our employees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Our trade secrets may also be obtained by third parties by other means, such as breaches of our physical or computer security systems. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

Claims by others that our products infringe their patents or other intellectual property rights could adversely affect our financial condition.

The healthcare industry has been characterized by frequent litigation regarding patent and other intellectual property rights. Patent applications are maintained in secrecy in the United States and also are maintained in secrecy outside the United States until the application is published. Accordingly, we can conduct only limited searches to determine whether our technology infringes the patents or patent applications of others. Any claims of patent infringement asserted by third parties would be time-consuming and could likely:

•result in costly litigation;

•divert the time and attention of our technical personnel and management;

•require us to develop non-infringing technology; or

•require us to enter into royalty or licensing agreements.

Research service studies are subject to cancellation based on changes in customer’s development plans.

Our revenue is primarily derived from studies performed for pharmaceutical and biotechnology companies to assist in the development of oncology drugs. There are many factors that could result in the change of our customers development plans for specific drugs, including without limitation to their research and development budgets and drug development strategies. These changes could lead to the cancellation or modification of on-going or planned studies. This would have a negative impact on the Company’s revenue growth and profit margin.

We face competition in the life science market for computational software and for bioinformatics products.

The market for our computational software platform for the life science market is competitive. We currently face competition from other scientific software providers, larger technology and solutions companies, in-house development by our customers and academic and government institutions, and the open-source community. Some of our competitors and potential competitors

have longer operating histories in certain segments of our industry than we do and could have greater financial, technical, marketing, research and development, and other resources. We could also face competition from open-source software initiatives, in which developers provide software and intellectual property free over the Internet. In addition, some of our customers spend significant internal resources in order to develop their own software. There can be no assurance that our current or potential competitors will not develop products, services, or technologies that are comparable to, superior to, or render obsolete, the products, services, and technologies we offer. There can be no assurance that our competitors will not adapt more quickly than we do to technological advances and customer demands, thereby increasing such competitors' market share relative to ours. Any material decrease in demand for our technologies or services may have a material adverse effect on our business, financial condition, and results of operations.

Drug development programs, particularly those in early stages of development, may never be commercialized.

Our future success depends, in part, on our ability to select successful product candidates, complete preclinical development of these product candidates and advance them to and through clinical trials. Early-stage product candidates in particular require significant investment in development, preclinical studies and clinical trials, regulatory clearances and substantial additional investment before they can be commercialized, if at all.

Our research and development programs may not lead to commercially viable products for several reasons, and are subject to the risks and uncertainties associated with drug development. For example, we may fail to identify promising product candidates, our product candidates may fail to be safe and effective in preclinical tests or clinical trials, or we may have inadequate financial or other resources to pursue discovery and development efforts for new product candidates. From time to time, we may establish and announce certain development goals for our product candidates and programs. However, given the complex nature of the drug discovery and development process, it is difficult to predict accurately if and when we will achieve these goals. If we are unsuccessful in advancing our research and development programs into clinical testing or in obtaining regulatory approval, our long-term business prospects will be harmed.

Impairment of goodwill may adversely impact future results of operations.

We have goodwill on our balance sheet. If the future growth and operating results of our business are not as strong as anticipated and/or our market capitalization declines, this could result in an impairment of our goodwill. To the extent any future impairment occurs, the carrying value of our assets will be written down to an implied fair value and an impairment charge will be made to our income from continuing operations. Such an impairment charge could materially and adversely affect our operating results.

Our ability to use our net operating loss carry-forwards and certain other tax attributes may be limited.

Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change” (generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period), the corporation’s ability to use its pre-change net operating loss carry-forwards and other pre-change tax attributes (such as research tax credits) to offset its post-change income may be limited. We believe that our 2016 public offering, taken together with our private placements and other transactions that have occurred since then, may have triggered an “ownership change” limitation. We may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carry-forwards to offset U.S. federal taxable income may be subject to limitations, which potentially could result in increased future tax liability to us.

We have a limited market for our common stock, which makes our securities very speculative.

Trading activity in our common stock is and has been limited. As a result, an investor may find it difficult to dispose of, or to obtain accurate quotations of the price of our common stock. There can be no assurance that a more active market for our common stock will develop, or if one should develop, there is no assurance that it will be sustained. This could severely limit the liquidity of our common stock, and would likely have a material adverse effect on the market price of our common stock and on our ability to raise additional capital. Furthermore, like many stocks quoted on the Nasdaq Capital Market, trading in our common stock is thin and characterized by wide fluctuations in trading prices, due to many factors that may have little to do with our operations or business prospects. This volatility could depress the market price of our common stock for reasons unrelated to operating performance.

Investment in our common stock may be diluted if we issue additional shares in the future.

We may issue additional shares of common stock, which will reduce shareholders’ percentage ownership and may dilute per share value. Our certificate of incorporation authorizes the issuance of 200,000,000 shares of common stock. As of July 23, 2026, we had 14,013,902 shares of common stock issued and 13,893,569 outstanding. The future issuance of all or part of the remaining authorized common stock would result in substantial dilution in the percentage of the common stock held by existing shareholders. The issuance of common stock for future services, acquisitions, or other corporate actions may have the effect of diluting the value of the shares held by existing shareholders, and might have an adverse effect on any market for our common stock.

To the extent that we raise additional funds by issuing equity securities or convertible debt securities in the future, our stockholders may experience significant dilution. Sale of additional equity and/or convertible debt securities at prices below certain levels will trigger anti-dilution provisions with respect to certain securities we have previously sold. If additional funds are raised through a credit facility or the issuance of debt securities or preferred stock, lenders under the credit facility or holders of these debt securities or preferred stock would likely have rights that are senior to the rights of holders of our common stock, and any credit facility or additional securities could contain covenants that would restrict our operation.

Potential future sales or issuances of our common stock to raise capital, or the perception that such sales could occur, could cause dilution to our current stockholders and the price of our common stock to fall.

We have historically supported our operations through the issuance of equity and may continue to do so in the future. Although we may not be successful in obtaining financing through equity sales on terms that are favorable to us, if at all, any such sales that do occur could result in substantial dilution to the interests of existing holders of our common stock.

Additionally, the sale of a substantial number of shares of our common stock or other equity securities to any new investors, or the anticipation of such sales, could cause the trading price of our common stock to fall.

Our stock price is volatile and therefore investors may not be able to sell their common stock at or above the price they paid for it.

The stock market in general and the market for biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may not be able to sell their common stock at or above the price they paid for it. The market price for our common stock may be influenced by many factors, including:

•regulatory developments in the United States and foreign countries;

•variations in our financial results or those of companies that are perceived to be similar to us;

•changes in the healthcare payment system overseas to the degree we receive revenue from such healthcare systems overseas;

•announcements by us of significant acquisition, strategic partnerships, joint ventures or capital commitments;

•sales of significant shares of stock by large investors;

•intellectual property, product liability, or other litigation against us; and

•the other key facts described in this “Risk Factors” section.

Certain provisions of our charter and bylaws and of our contractual agreements contain provisions that could delay and discourage takeover attempts and any attempts to replace our current management by stockholders.

Certain provisions of our certificate of incorporation and bylaws, and our contractual agreements could make it difficult for or prevent a third party from acquiring control of us or changing our board of directors (the "Board" or "Board of Directors") and management. These provisions include:

•requirements that our stockholders comply with advance notice procedures in order to nominate candidates for election to our Board of Directors or to place stockholders’ proposals on the agenda for consideration at meetings of stockholders; and

•in connection with private placements of our stock in 2011, 2013 and 2015, we covenanted that we would not merge or consolidate with another company unless either the transaction and the trading volume of our stock met certain thresholds and qualifications or we obtained the consent of certain of the investors who purchased our stock in those private placements.

Certain provisions of Delaware law make it more difficult for a third party to acquire us and make a takeover more difficult to complete, even if such a transaction were in the stockholders’ interest.

The Delaware General Corporation Law contains provisions that may have the effect of making it more difficult or delaying attempts by others to obtain control of us, even when these attempts may be in the best interests of our stockholders. We also are subject to the anti-takeover provisions of the Delaware General Corporation Law, which prohibit us from engaging in a “business combination” with an “interested stockholder” unless the business combination is approved in a prescribed manner and prohibit the voting of shares held by persons acquiring certain numbers of shares without obtaining requisite approval. The statutes have the effect of making it more difficult to effect a change in control of a Delaware company.

Our management and four significant stockholders collectively own a substantial majority of our common stock.

Collectively, our officers, our directors and four significant stockholders own or exercise voting and investment control of approximately 71% of our outstanding common stock as of July 23, 2026. As a result, investors may be prevented from affecting matters involving our company, including:

•the composition of our Board of Directors and, through it, any determination with respect to our business direction and policies, including the appointment and removal of officers;

•any determinations with respect to mergers or other business combinations;

•our acquisition or disposition of assets; and

•our corporate financing activities.

Furthermore, this concentration of voting power could have the effect of delaying, deterring or preventing a change of control or other business combination that might otherwise be beneficial to our stockholders. This significant concentration of share ownership may also adversely affect the trading price for our common stock because investors may perceive disadvantages in owning stock in a company that is controlled by a small number of stockholders.

We have not paid any cash dividends in the past and have no plans to issue cash dividends in the future, which could cause the value of our common stock to have a lower value than other similar companies which do pay cash dividends.

We have not paid any cash dividends on our common stock to date and do not anticipate any cash dividends being paid to holders of our common stock in the foreseeable future. While our dividend policy will be based on the operating results and capital needs of the business, it is anticipated that any earnings will be retained to finance our future expansion. As we have no plans to issue cash dividends in the future, our common stock could be less desirable to other investors and as a result, the value of our common stock may decline, or fail to reach the valuations of other similarly situated companies who have historically paid cash dividends in the past.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they change their recommendations regarding our common stock adversely, the price of our common stock and trading volume could decline.

The trading market for our common stock may be influenced by the research and reports that securities or industry analysts may publish about us, our business, our market or our competitors. If any of the analysts who may cover us change their recommendation regarding our common stock adversely, or provide more favorable relative recommendations about our competitors, the price of our common stock would likely decline. If any analyst who may cover us was to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the price of our common stock or trading volume to decline.

Our business operations could be disrupted if our information technology systems fail to perform adequately.

We rely on information technology networks and systems, including the Internet, to process, transmit, and store information, to manage and support a variety of business processes and activities, and to comply with regulatory, legal, and tax requirements. Our information technology systems, some of which are dependent on services provided by third parties, may be vulnerable to damage, interruption, or shutdown due to any number of causes outside of our control such as catastrophic events, natural disasters, fires, power outages, systems failures, telecommunications failures, employee error or malfeasance, security breaches, computer viruses or other malicious codes, ransomware, unauthorized access attempts, denial of service attacks, phishing, hacking, and other cyberattacks. While we have experienced threats to our data and systems, to date, we are not aware that we have experienced a material breach. Cyberattacks are occurring more frequently, are constantly evolving in nature and are becoming more sophisticated. Additionally, continued geopolitical turmoil, including the Russia-Ukraine military conflict, has heightened the risk of cyberattacks. While we attempt to continuously monitor and mitigate against cyber risks, we may incur significant costs in protecting against or remediating cyberattacks or other cyber incidents.

Sophisticated cybersecurity threats pose a potential risk to the security and viability of our information technology systems, as well as the confidentiality, integrity, and availability of the data stored on those systems, including cloud-based platforms. In addition, new technology that could result in greater operational efficiency may further expose our computer systems to the risk of cyber-attacks. If we do not allocate and effectively manage the resources necessary to build and sustain the proper technology infrastructure and associated automated and manual control processes, we could be subject to billing and collection errors, business disruptions, or damage resulting from security breaches. If any of our significant information technology systems suffer severe damage, disruption, or shutdown, and our business continuity plans do not effectively resolve the issues in a timely manner, our product sales, financial condition, and results of operations may be materially and adversely affected, and we could experience delays in reporting our financial results. In addition, there is a risk of business interruption, violation of data privacy laws and regulations, litigation, and reputational damage from leakage of confidential information. Any interruption of our information technology systems could have operational, reputational, legal, and financial impacts that may have a material adverse effect on our business.

A pandemic, epidemic, or outbreak of an infectious disease in the United States or elsewhere may adversely affect our business and we are unable to predict the potential impact.

We are subject to risks related to public health crises Any outbreak of contagious diseases, or other adverse public health developments, could have a material and adverse effect on our business operations. These could include disruptions or restrictions on our ability to travel, pursue partnerships and other business transactions, receive shipments of biologic materials, as well as be impacted by the temporary closure of the facilities of suppliers. The spread of an infectious disease may also result in the inability of our suppliers to deliver supplies to us on a timely basis. In addition, health professionals may reduce staffing and reduce or postpone meetings with clients in response to the spread of an infectious disease. Though we have not yet experienced such events, if they would occur, they could result in a period of business disruption, and in reduced operations, any of which could materially affect our business, financial condition and results of operations. However, as of the date of this Annual Report, we have not experienced a material adverse effect on our business nor the need for reduction in our work force; and, currently, we do not expect any material impact on our long-term activity. The extent to which any spread of disease impacts our business will depend on future developments which are highly uncertain and cannot be predicted, including, but not limited to, information which may emerge concerning the spreading and severity of the any infectious diseases, the actions to contain these, or treat their impact.

Deterioration in general economic conditions in the United States and globally, including the effect of prolonged periods of inflation on our customers and suppliers, could harm our business and results of operations.

Our business and results of operations could be adversely affected by changes in national or global economic conditions. These conditions include but are not limited to inflation, rising interest rates, availability of capital markets, energy availability and costs (including fuel surcharges), the negative impacts caused by pandemics and public health crises, negative impacts resulting from the military conflicts between Russia and the Ukraine and/or in the Middle East, and the effects of governmental initiatives to manage economic conditions. Impacts of such conditions could be passed on to our business in the form of a reduced customer base and/or potential for new bookings due to possible reductions in pharmaceutical and biotech industry-wide spend on research and development and/or economic pressure on our suppliers to pass on increased costs.

Our Chairman of the Board of Directors resides in Israel and we have several customers with their operations located in Israel, and, therefore, our leadership continuity and results may be adversely affected by political, economic, and military instability in Israel.

One of our wholly owned subsidiaries is based in Israel. While we do not have a physical facility located in Israel, our Chairman of the Board of Directors resides there and we have several customers whose operations are based there. Accordingly, political, economic, and military conditions in Israel may directly affect our business. Since the establishment of the modern State of Israel in 1948, a number of armed conflicts have taken place between Israel and its neighboring countries. Any hostilities involving Israel or the interruption or curtailment of trade between Israel and its trading partners could adversely affect our business, results of operations, and leadership continuity.

Any armed conflicts, war, terrorist activities, or political instability in the region and the consequences thereof, such as our customers' ability to conduct operations and pay their suppliers of goods and services (such as our company), could adversely affect business conditions and could harm our results of operations.

It is currently not possible to predict the duration or severity of the ongoing wars with Iran and its proxies, or its effects on our business, operations, and financial conditions. The ongoing wars could disrupt our customers' business and operations. While we have not experienced any disruptions that have materially impacted our business or results of operations, there can be no assurances that further unforeseen events will not have a material adverse effect on us or our operations in the future.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Risk Management and Strategy

We believe we maintain an information technology and security program appropriate for a company of our size, taking into account our operations and risks. We recognize the critical importance of maintaining the trust and confidence of our investors, employees, customers and vendors. We have implemented cybersecurity processes designed to assess, identify, and manage risks from potential unauthorized occurrences on or through our information technology systems that may result in adverse effects on the confidentiality, integrity, and availability of these systems and the data residing therein. These processes include mechanisms, controls, and certain technologies designed to prevent or mitigate system intrusion or data loss, theft, misuse, or other security incidents or vulnerabilities and maintain a stable and secure information technology environment. For example, we conduct ongoing monitoring of critical systems for any compromised or potentially compromised accounts. We conduct regular trainings on cyber and information security, along with phishing simulations, among other topics. In addition, we consult with an outside information technology consultant on a regular basis to assist with assessing, identifying, and managing cybersecurity risks, including to anticipate future threats and trends, and their impact on the Company’s risk environment.

Governance

Our Board of Directors oversees our risk management process. The Audit Committee, by way of Board delegation, retains oversight of the Company’s cybersecurity risks. The senior leadership team, including our Chief Financial Officer and Chief Executive Officer, provides periodic reports to our Board, as applicable. Our Director of Information Technology Strategy and Operations is responsible for leading the assessment and management of cybersecurity threats and periodically updating the Audit Committee as needed.

To date, we have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected us, including our operations, business strategy, results of operations, or financial condition.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis together with our consolidated financial statements and the related notes included elsewhere in this Annual Report. This discussion contains forward-looking statements that are based on our current expectations, estimates, and projections about our business and operations. Our actual results may differ materially from those currently anticipated and expressed in such forward-looking statements as a result of a number of factors, including those we discuss under Item 1A – “Risk Factors” and elsewhere in this Annual Report.

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 stimulate 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 Patient Derived Xenograft ("PDX") 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 access to certain PDX model data via licensing agreements. As our Platform has been expanded over time with the collection of models and the enhancement of their characterization, we have developed a robust multi-omic dataset with substantial potential for both drug discovery and development. This dataset serves as a vital resource for both our pharmaceutical and biotechnology customer who gain access to model-specific data and further their research via licensed access.

We also offer Lumin Bioinformatics ("Lumin"), an oncology data-driven software program which contains comprehensive information derived from our research services and clinical studies. Lumin leverages Champions’ large Datacenter coupled with analytics and artificial intelligence to provide a robust tool for computational cancer research. It is the combination of the Datacenter and the analytics that create a foundation for Lumin. 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 rich and unique 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 rapidly 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 early stage 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. Any expenses associated with this part of our business are research and development and are expensed as incurred.

Results of Operations

The following table summarizes our operating results for the periods presented below (dollars in thousands):


	For the Years Ended April 30,
	2026		% of Revenue		2025		% of Revenue		% Change

Oncology revenue	$	59,425	100.0	%	$	56,944	100.0	%	4.4	%

Costs and operating expenses:
Cost of oncology revenue	30,900		52.0		28,389		49.9		8.8

Total costs and operating expenses	60,565		102.0		52,391		92.0		15.6

Income (loss) from operations	(1,140)		(2.0)		4,553		8.0		(125.0)

Oncology Revenue

Oncology revenue, which is primarily derived from research services, was $59.4 million and $56.9 million, for the years ended April 30, 2026 and 2025, respectively, an increase of $2.5 million, or 4.4%.

Our revenues are comprised of the following:


	For the Years Ended April 30,
(in 000s)	2026		2025
Pharmacology services	$	57,133	$	48,585
TOS data license revenue	764		4,676
Other TOS revenue	1,528		3,683

Total oncology revenue	$	59,425	$	56,944

Pharmacology Services

•Pharmacology services revenue increased for the year ended April 30, 2026 compared to the prior year. The increase was primarily driven by improved conversion of previously booked studies into revenue, including studies that had been expected to convert in the prior fiscal year but were delayed into fiscal 2026. The timing and progress of study activity can impact the period in which bookings convert to revenue.

TOS Data License Revenue

•TOS data license revenue decreased for the year ended April 30, 2026 compared to the prior year. Fiscal 2025 revenue primarily reflected a significant data license transaction with a single customer, while fiscal 2026 revenue was generated from multiple, smaller customer contracts. Although fiscal 2026 did not include a comparable large transaction, the Company expanded its data licensing customer base during the year.

Other TOS Revenue

•Other TOS revenue includes additional clinical services provided to the Company's pharmaceutical and biotechnology customers specifically for flow cytometry and SaaS provided via Lumin. Other TOS revenue decreased for the year ended April 30, 2026 compared to the prior year, primarily due to lower flow cytometry revenue as the Company strategically shifted its focus and investment away from this area of the business.

Cost of Oncology Revenue

Cost of oncology revenue was $30.9 million and $28.4 million for the years ended April 30, 2026 and 2025, respectively, an increase of $2.5 million or 8.8%. The increase was primarily driven by higher outsourced laboratory costs associated with the expansion of our radiopharmacology services. During fiscal 2026, we transitioned these capabilities in-house, which we expect will reduce our reliance on outsourced laboratory services and associated costs for fiscal 2027.

Research and Development

Research and development expense was $9.1 million and $6.8 million for the years ended April 30, 2026 and 2025, respectively, an increase of $2.3 million or 33.1%.

The significant components of research and development expense were comprised of the following:


	Years Ended April 30,
(in 000s)	2026		2025
Compensation	$	3,400	$	2,800
Laboratory Supplies	2,400		2,000
Mice Costs	130		550
Outside Services	2,270		590

Research and development expense increased $2.3 million, or 33.1% for the year ended April 30, 2026 compared to the prior year. The increase was primarily driven by increased investment in the Company's data platform, including higher sequencing and laboratory costs, as well as higher compensation expenses associated with these initiatives.

Sales and Marketing

Sales and marketing expense increased $1.8 million or 23.5% for the year ended April 30, 2026 compared to the prior year. The increase was primarily driven by higher compensation costs associated with the expansion of the Company's commercial organization, including personnel supporting both its pharmacology services and data licensing businesses.

General and Administrative

General and administrative expense increased $1.8 million, or 19.4% for the year ended April 30, 2026 compared to the prior year. The increase was primarily driven by higher information technology costs, stock-based compensation and compensation-related expenses, including costs associated with changes in executive leadership.

Loss on Disposal of Equipment

Loss on disposal of equipment was $111,000 and $293,000 for the years ended April 30, 2026 and 2025, respectively, a decrease of $182,000 or 62%. For both years ended April 30, 2026 and 2025, the losses resulted from the disposal of equipment which could no longer be utilized and had a net book value, or carrying value on the balance sheet, as of the disposal date.

Other Income, net

Other income, net, was $211,000 and $73,000 for the years ended April 30, 2026 and 2025, respectively. The increase was primarily attributable to higher interest income.

Income Taxes, net

For the years ended April 30, 2026 and 2025, the Company recognized income tax expense of $246,000 and an income tax benefit of $75,000, respectively. For the year ended April 30, 2026, income tax expense of $246,000 is mainly attributable to U.S. state income taxes due to net operating loss limitations and taxable income earned in Israel and Italy relating to transfer pricing. For the year ended April 30, 2025, the income tax benefit of $75,000 is related to the same items as indicated for the year ending 2026, net of a $181,000 reversal of an uncertain tax liability in Israel.

Liquidity and Capital Resources

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. In the past, we have met these cash requirements through our cash on hand, working capital management, proceeds from certain private placements and public offerings of our securities and sales of products and services. For the years ended April 30, 2026 and 2025, the Company had a net loss of approximately $1.2 million and net income of approximately $4.7 million, respectively. As of April 30, 2026, the Company had an accumulated deficit of approximately $81.1 million, negative working capital of $703,000 and cash of $4.9 million. For the twelve months ended April 30, 2026, the Company used cash flow from operations of approximately $4.5 million. Despite our negative working capital at this date and use of cash from operations, we believe that our cash on hand, together with expected cash flows from operations, are adequate to fund operations through at least August 2027. 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.

Cash Flows

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

Cash Flows from Operating Activities

Net cash used in operating activities was $4.5 million for the year ended April 30, 2026 compared to net cash provided by operating activities of $7.4 million for the year ended April 30, 2025. The decrease was primarily driven by a $6.6 million decrease in deferred revenue, compared to a $3.3 million increase in the prior year. The decrease in deferred revenue was primarily attributable to lower bookings and the timing of customer billings and study activity. Cash flow from operations was also impacted by the net loss in fiscal 2026 and an increase in accounts receivable, partially offset by an increase in accounts payable.

Cash Flows from Investing Activities

Net cash used in investing activities was $540,000 and $389,000 for the years ended April 30, 2026 and 2025, respectively. The cash used was for the investment in lab and computer equipment which, in fiscal 2026, was partially offset by proceeds from the sale of certain equipment.

Cash Flows from Financing Activities

Net cash provided by financing activities was $99,000 for the year ended April 30, 2026. Net cash provided by financing activities was $170,000 for the year ended April 30, 2025. Cash flows provided by financing activities in both 2026 and 2025 was generated from the proceeds of stock option exercises offset by financing lease payments.

Critical Accounting Policies

We prepare our Consolidated Financial Statements in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). Our significant accounting policies are described in Note 2 - Summary of Significant Accounting Policies to our Consolidated Financial Statements attached hereto. We believe the following critical accounting policies involve the most significant judgments and estimates used in the preparation of our Consolidated Financial Statements.

Revenue Recognition

The Company accounts for revenue under the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers. In accordance with ("ASC 606"), revenue is recognized when, or as, a customer obtains control of promised services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these services.

A performance obligation is a promise (or a combination of promises) in a contract to transfer distinct goods or services to a customer and is the unit of accounting under ASC 606 for the purposes of revenue recognition. A contract's transaction price is allocated to each separate performance obligation based upon the standalone selling price and is recognized as revenue, when, or as, the performance obligation is satisfied. The majority of the Company's contracts have a single performance

obligation because the promise to transfer individual services is not separately identifiable from other promises in the contracts, and therefore, is not distinct.

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 when they meet the criteria under ASC 606-10-25-12.

Stock-Based Payments

We typically recognize expense for stock-based payments based on the fair value of awards on the date of grant. We use the Black-Scholes option pricing model to estimate fair value. The option pricing model requires us to estimate certain key assumptions such as expected life, volatility, risk free interest rates, and dividend yield to determine the fair value of stock-based awards. These assumptions are based on historical information and management judgment. We expense stock-based payments over the period that the awards are expected to vest. In the event of forfeitures, compensation expense is adjusted.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, “Improvements to Tax Disclosures” (Topic 740). The new guidance is intended to enhance the transparency and decision usefulness of income tax disclosures through changes to the rate reconciliation and the income taxes paid information disclosed. The ASU is effective retrospectively for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this ASU as of May 1, 2025, and it has been included in the required disclosures in our financial statements since.

In November 2024 and January 2025, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures" (Subtopic 220-40) "Disaggregation of Income Statement Expenses" and ASU 2025-01 "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures" (Subtopic 220-40): Clarifying the Effective Date". The new guidance is intended to enhance transparency and disclosures by requiring public business entities to disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The ASU is effective for the first annual reporting periods after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is in the process of evaluating the impact that the adoption of this ASU will have on its financial statements and related disclosures, which is not expected to be material.

Management's Report on Disclosure Controls and Procedures

Our management, under the supervision and with the participation of our Principal Executive Officer (our Chief Executive Officer) and Principal Financial Officer (our Chief Financial Officer), has evaluated the effectiveness of our disclosure controls and procedures as of April 30, 2026, the end of our fiscal year covered by this Annual Report. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or person performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of April 30, 2026, our Chief Executive Officer and Chief Financial Officer have concluded that, as of April 30, 2026, our disclosure controls and procedures are effective.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. This rule defines internal control over financial reporting as a process designed by, or under the supervision of, Company management to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Management has assessed the effectiveness of our internal control over financial reporting using the components established in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

A system of internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A material weakness is any deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our internal control over financial reporting was effective as of April 30, 2026, the end of the fiscal year covered by this Annual Report.

Changes in Internal Controls

There were no changes in the Company’s internal controls over financial reporting during the quarter ended April 30, 2026, that materially affected, or were reasonably likely to materially affect the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Champions Oncology, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Champions Oncology, Inc. and Subsidiaries (the “Company”) as of April 30, 2026 and 2025, and the related consolidated statements of operations, stockholders’ equity (deficiency), and cash flows for each of the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the consolidated financial position of the Company as of April 30, 2026 and 2025, and the consolidated results of their operations and their cash flows for each of the years then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

We have served as the Company’s auditor since 2015.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Basis of Presentation

Background

Champions Oncology, Inc. ("we", "our", or the “Company”), is engaged in drug discovery and development through data-driven research strategies and innovative pharmacology, biomarker and data platforms. The Company’s TumorGraft Technology Platform ("the "Platform”), a comprehensive bank (the "Bank") of unique, well characterized "Patient Derived XenoGrafts" (PDX) models, is an approach to personalizing cancer care based upon the implantation of human tumors in immune-deficient mice. The Company provides a technology platform to pharmaceutical and biotechnology companies using proprietary TumorGraft studies, which the Company believes may be predictive of how drugs may perform in clinical settings. Utilizing the Platform, the Company offers multiple services to pharmaceutical and biotechnology companies seeking personalized approaches to drug development. By performing studies to predict the efficacy of oncology drugs, our Platform is designed to facilitate drug discovery with lower costs and increased speed of drug development as well as increased adoption of existing drugs.

The Company has four operating subsidiaries: Champions Oncology (Israel), Limited, Champions Biotechnology U.K., Limited, Champions Oncology S.R.L., and Corellia AI, Inc. For the years ended April 30, 2026 and 2025, there were no revenues earned by these subsidiaries.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Company operates in one reportable business segment.

The Company's wholly owned subsidiary, Corellia, has issued equity‑classified stock options to certain of its employees. Stock‑based compensation expense is recognized over the requisite service period, with the corresponding equity recorded as non-controlling interest in the consolidated statements of stockholders' equity. Because the options are unexercised, they do not represent an actual ownership interest, and no portion of the Company's net income or loss is attributed to non-controlling interest until the options are exercised. Refer to Note 8.

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Foreign Currency

The Company’s foreign subsidiaries' functional currency 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.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience, our observance of trends in particular areas and information or valuations and various other assumptions that we believe to be reasonable under the circumstances and which form the basis for making judgments about the carrying value of assets and liabilities that may not be readily apparent from other sources. Actual amounts could differ significantly from amounts previously estimated.

Cash and Cash Equivalents

CHAMPIONS ONCOLOGY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 April 30, 2026 and 2025, the Company had cash balances of $4.9 million and $9.8 million, respectively, and no cash equivalents. The Company maintains its cash balances in three major financial institutions which exceed federally insured limits. The Company regularly monitors the financial stability of these financial institutions and believes that it is not exposed to any significant credit risk in its cash. If any liquidity and/or financial stability concerns arise with respect to banks and financial institutions, either nationally or in specific regions, the Company's ability to access cash or enter into new financing arrangements may be threatened, which could have a material adverse effect on its business, financial condition and results of operations.

Liquidity

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. In the past, we have met these cash requirements through our cash on hand, working capital management, proceeds from certain private placements and public offerings of our securities, and sales of products and services. For the year ended April 30, 2026, the Company had a net loss of approximately $1.2 million, an accumulated deficit of approximately $81.1 million, negative working capital of approximately $703,000 and cash of $4.9 million. Despite the negative working capital, we believe that our cash on hand, together with expected cash flows from operations, are adequate to fund operations through at least August 2027. 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. The Company has no assets or liabilities that are measured at fair value on a recurring and/or non-recurring basis during the years ended April 30, 2026 and 2025.

Property and Equipment

Property and equipment is recorded at cost and primarily consists of laboratory equipment, furniture and fixtures, computer hardware and software, leasehold improvements, and internally developed software. Assets in progress include equipment or software not yet placed in service. Depreciation and amortization is calculated on a straight-line basis over the estimated useful lives of the various assets ranging from three to seven years. Refer to Footnote 4, "Property and Equipment" for a detailed discussion.

Leases

The Company accounts for its leases under Financial Accounting Standards Board ("FASB") ASC Topic 842, Leases ("ASC 842"). 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 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 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.

Amortization expense for the ROU asset associated with its finance leases is recognized on a straight-line basis over the term of the lease and interest expense associated with its finance lease is recognized on the balance of the lease liability using the effective interest method based on the estimated incremental borrowing rate.

CHAMPIONS ONCOLOGY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Impairment of Long-Lived Assets

Impairment losses are to be recognized when the carrying amount of a long-lived asset is not recoverable or exceeds its fair value. The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that a carrying value may not be recoverable. The Company uses estimates of future cash flows over the remaining useful life of a long- lived asset or asset group to determine the recoverability of the asset. These estimates only include the net cash flows directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of the asset or asset group. The Company did not recognize any impairment losses for the Company’s long-lived assets for the years ended April 30, 2026 and 2025 . Refer to Note 4, "Property and Equipment".

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company evaluates the carrying value of goodwill annually in connection with the annual budgeting and forecast process and also between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit to which goodwill was allocated to below its carrying amount. Such circumstances could include, but are not limited to: (1) a significant adverse change in legal factors, market conditions, or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator. When evaluating goodwill for impairment, the Company may first perform an assessment qualitatively whether it is more likely than not that a reporting unit’s carrying amount exceeds its fair value, referred to as a “step zero” approach. Subsequently (if necessary after step zero), an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying value. Under FASB's Accounting Standards Update ("ASU") 2014-02, Topic 350, "Intangibles—Goodwill and Other" goodwill impairment is measured as the excess of the carrying amount of the reporting unit over its fair value.

Judgments regarding the existence of impairment indicators are based on legal factors, market conditions and operational performance of the businesses. Future events, including but not limited to continued declines in economic activity, loss of contracts or a significant number of customers, or a rapid increase in costs or capital expenditures, could cause the Company to conclude that impairment indicators exist and that goodwill is impaired. For the years ended April 30, 2026 and 2025, the Company's annual assessment did not result in any impairment indicators.

Cost of Oncology Revenue

Cost of oncology revenue consists of direct costs related to laboratory supplies, mice purchases, and maintenance costs for studies completed internally as well as charges from Contract Research Organizations for studies handled externally. Indirect costs include salaries and other payroll related costs of compensation for personnel directly engaged in providing Translational Oncology Solutions ("TOS") products and services. All costs of performing studies in-house are expensed as incurred. All costs of performing studies from external sources are expensed when incurred.

Research and Development

Research and development costs represent both costs incurred internally for research and development activities, including personnel costs, mice purchases, and maintenance, as well as costs incurred externally to facilitate research activities, such as tumor tissue procurement and characterization expenses. All research and development costs are expensed as incurred.

Sales and Marketing

Sales and marketing expenses represent costs incurred to promote the Company’s products offered, including salaries, benefits and related costs of our sales and marketing personnel, and represent costs of advertising and other selling and marketing expenses. All sales and marketing costs, including advertising costs, are expensed as incurred.

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 using the treasury method. Dilutive earnings per share is not presented when it would be antidilutive to do so.

CHAMPIONS ONCOLOGY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Stock-based Payments

The Company generally recognizes expense for stock-based payments based on the fair value of awards on the date of grant. The Company primarily uses the Black-Scholes option pricing model to estimate fair value. If awards contain market-based vesting conditions, a Monte Carlo simulation model is used to estimate fair value. The Black-Scholes option valuation model was developed for use in estimating the fair value of short-traded options that have no vesting restrictions and are fully transferable. The Monte Carlo simulation model is a generally accepted valuation technique that incorporates multiple potential future stock price paths and is particularly appropriate for awards with market-based performance conditions, as it captures the probability of achieving the applicable market condition over the expected term of the award.

Both valuation models require the Company to estimate certain key assumptions such as expected life, volatility, risk free interest rates and dividend yield, as applicable, to determine the grant date fair value of stock-based awards. These assumptions are based on historical information and management judgment. The risk-free interest rate used is based on the United States treasury security rate with a term consistent with the expected term of the award at the time of the grant. Since the Company has limited option exercise history, it has generally elected to estimate the expected life of an award based upon the Securities and Exchange Commission-approved “simplified method” noted under the provisions of Staff Accounting Bulletin No. 107 with the continued use of this method extended under the provisions of Staff Accounting Bulletin No. 110. Estimated volatility is based upon the historical volatility of the Company's common stock. The Company does not anticipate paying a dividend, and therefore, no expected dividend yield was used. For awards valued using the Monte Carlo simulation model, the valuation also incorporates the probability of achieving the applicable market condition and, where applicable, the correlation of the Company's stock price with the relevant market index or peer group. Forfeitures are accounted for as they occur.

The Company expenses stock-based payments over the period that the awards are expected to vest. The Company expenses modification charges in the period of modification and, if required, over the remaining period the awards are expected to vest.

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 operating history, a valuation allowance is established. The Company adjusts the valuation allowance in the period management determines it is more likely than not that net 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 April 30, 2026 and 2025, the Company provided a valuation allowance for all net deferred tax assets, as recovery is not more likely than not 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. As of April 30, 2026 and 2025, the Company did not record any liabilities related to uncertain tax positions. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company did not accrue any interest or penalties in the Company’s consolidated statements of operations for the years ended April 30, 2026 and 2025.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, "Revenue from Contracts with Customers". The objective of the standard is to establish a single comprehensive revenue recognition model that is designed to create greater comparability of financial statements across industries and jurisdictions. 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.

CHAMPIONS ONCOLOGY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

All revenue is generated from contracts with customers. 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 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 toward the complete satisfaction of the performance obligation.

License Revenue

The Company also enters into contracts to provide access to certain Patient Derived Xenograft ("PDX") model data via a license agreement with payments based on a fixed-fee arrangement. The Company's current data licenses contain a single performance obligation of delivering access to the data license. The Company recognizes this license revenue up-front, at a point in time, when the performance obligation is satisfied with the delivery of the data.

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.

Accounts 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, with terms generally being 30-90 days. 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

CHAMPIONS ONCOLOGY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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. Unbilled services are classified as a component of accounts receivable on the balance sheet.

Accounts receivable are customer obligations due under normal trade terms. The Company extends credit to its customers based on their creditworthiness and historical data and performs ongoing credit evaluations of our customers’ financial condition. The Company maintains a provision for estimated credit losses related to accounts receivable for future expected bad debt resulting from the inability or unwillingness of our customers to make required payments. We estimate our provision for estimated credit losses based on relevant information such as historical experience, current economic conditions, and future expectations of specifically identified customer balances. This provision is adjusted as appropriate to reflect current conditions. After all attempts to collect a receivable have failed, the receivable is written off against the provision. We do not obtain collateral from our customers to secure accounts receivable.

Deferred revenue consists of unearned payments received in excess of revenue recognized. As the contracted services are subsequently performed and the associated revenue 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 consolidated balance sheet as the Company expects to recognize the associated revenue in less than one year.

Segment Reporting

Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the Company’s chief operating decision maker (“CODM”) and relied upon when making decisions regarding resource allocation and assessing performance. When evaluating the Company’s financial performance, the CODM reviews total revenues, total expenses, and expenses by functional classification, using this information to make decisions on a Company-wide basis.

The Company currently operates in one reportable segment pertaining to oncology services. The CODM for the Company is the Chief Executive Officer (the “CEO”). The Company’s CEO reviews operating results on an aggregate basis and manages the Company’s operations on a consolidated basis for the purpose of evaluating financial performance and allocating resources. Accordingly, the Company has determined that it has a single reportable and operating segment structure. The CEO uses net income or loss as well as revenue results to allocate resources in the annual budgeting and forecasting process and also uses that measure as a basis for evaluating financial performance regularly by comparing actual results with established budgets and forecasts. All significant expense categories are presented on our Consolidated Statements of Operations. The measure of segment assets is reported on the Consolidated Balance Sheet as total assets. Segment revenues and expenses are identical to that disclosed in the accompanying Consolidated Statements of Operations.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period’s presentation.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, “Improvements to Tax Disclosures” (Topic 740). The new guidance is intended to enhance the transparency and decision usefulness of income tax disclosures through changes to the rate reconciliation and the income taxes paid information disclosed. The ASU is effective retrospectively for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this ASU, retrospectively, as of May 1, 2025 and it has been included in the required disclosures in the Company's financial statements.

Note 7. 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 a private placement in March 2015. 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 PDX models and use in our TOS business. These types of arrangements have an upfront fee ranging from approximately 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 years ended April 30, 2026 and 2025, the Company has recognized approximately $594,000 and $462,000 in expense related to these royalty arrangements, respectively. Royalty expense is included in cost of oncology revenue in the accompanying consolidated statements of operations.

In general, these Plans provide for stock-based compensation to the Company’s employees, directors and non-employees. The 2010 and 2021 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

CHAMPIONS ONCOLOGY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

As part of the 2021 Annual Shareholders Meeting, shareholders approved the adoption of the 2021 Equity Incentive Plan (“2021 Equity Plan”).

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 Board of Directors (the "Board") or Chief Executive Officer. 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 April 30, 2026, approximately 80,000 shares were left to issue under this plan and 1.9 million options granted under the 2021 plan were outstanding.

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 30,000,000 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. 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. As of April 30, 2026, approximately 732,000 options granted under the 2010 plan were still outstanding.

2023 Global Equity Incentive Plan

As part of the establishment of Corellia, the subsidiary's Board of Directors approved the adoption of the 2023 Global Equity Incentive Plan ("the Plan"). The purpose of the Plan is to grant (i) Non-statutory Stock Options; (ii) Incentive Stock Options; and/or (iii) Restricted Stock Awards (collectively, stock-based compensation) to its employees, directors and non-employees. Options expire no later than ten years from the date of grant. Options awards vest as follows, unless otherwise determined by the subsidiary's Board or Plan Administrator, twenty-five percent (25%) of the options grant on the first anniversary of the vesting commencement date (and in the absence of such determination, of date on which such Options were granted), and six and one-quarter percent (6.25%) of the options grant at the end of each subsequent three-month period thereafter over the course of the following three (3) years.

Director Compensation Plan

On December 12, 2013, the Compensation Committee of the Board (the "Committee") adopted changes to the Director Compensation Plan of 2010 (the “Director Plan”) effective December 1, 2013. Under the Director Plan, independent directors of the Company were entitled to an annual award of a five-year option to purchase 8,333 shares of the Company’s common stock, and the Chairman of the Board of the Company was entitled to an annual award of a five-year option to purchase 16,667 shares of the Company’s common stock. Independent directors who serve as chairperson of a committee were also to receive an annual grant of a five-year option to purchase 1,667 shares of the Company’s common stock.

During fiscal year 2021, the Committee adopted the Director Compensation Plan of 2021 (the "2021 Plan"). Under the 2021 Plan, independent directors are entitled to an annual base compensation of $100,000 which can be received in either ten-year options to purchase shares of the Company's stock, which vest fully over a one-year period, or a combination of options and cash, where cash received is not to exceed $35,000. The Chairman of the Board’s annual compensation was set at an equivalent of $150,000. Compensation for independent directors who serve as chairperson of a committee was set at an equivalent of between $110,000 to $120,000. All options issued under the 2021 Plan vest quarterly at a rate of 25%. Option grants will typically be issued after the annual shareholder meeting which will generally be held in October of each year. New directors will receive compensation upon joining the Board equal to a pro-rata equivalent for the remainder of the year. Options issued under the 2021 Plan are issued pursuant to the 2021 Equity Plan.

Management has evaluated the available evidence about future tax planning strategies, taxable income, and other possible sources of realization of deferred tax assets and has established a full valuation allowance against its net deferred tax assets as of April 30, 2026 and 2025. For the years ended April 30, 2026 and 2025, the Company recorded a valuation allowance of $16.3 million and $14.8 million, respectively. The net increase in the valuation allowance of $1.5 million during the fiscal year ended April 30, 2026, was mainly due to increases in the deferred tax assets related to the net operating loss carryforward, net of decreases for other timing differences. The net increase of $1.5 million related to the U.S. federal and state/local jurisdictions of $0.1 million and $1.4 million, respectively. The valuation allowance related to the state/local jurisdictions increased mainly due to changes in the blended state statutory tax rate due to changes in state apportionment percentages.

The net decrease in the valuation allowance of $3.3 million during the fiscal year ended April 30, 2025, was mainly due to decreases in the deferred tax assets related to the net operating loss carryforward, stock-based compensation, and capitalized research expenses. The net decrease of $3.3 million related to the U.S. federal and state/local jurisdictions of $3.1 million and $200,000, respectively. Management continues to assess the realizability of the deferred tax assets at each interim and annual balance sheet date based upon actual and forecasted operating results.

As of April 30, 2026 and 2025, the Company’s estimated U.S. net operating loss carry-forwards were approximately $41.0 million and $35.1 million, respectively. Net operating losses generated prior to May 1, 2018 have a 20-year carryforward and will begin expiring in 2034 for federal and 2031 for state and local tax purposes. Losses generated in the fiscal years since the year ended April 30, 2019 may be carried forward indefinitely. A valuation allowance has been recorded against all of the deferred tax assets related to the loss carryforwards.

Under the provisions of the Internal Revenue Code, certain substantial changes in the Company’s ownership may result in a limitation on the amount of net operating losses that may be utilized in future years. During the fiscal year ended April 30, 2013, approximately $12.0 million of the Company’s net operating losses became subject to limitation under Internal Revenue Code Section 382 in connection with an ownership change on January 28, 2013. As a result of the ownership change, the Company’s annual limitation on its use of net operating loss carry-forwards is approximately $432,000.

The Company files income tax returns in various jurisdictions with varying statutes of limitations. As of April 30, 2026, the earliest tax year still subject to examination for state purposes is fiscal 2022. The Company’s tax years for periods ending April 30, 2014 and forward are subject to examination by the United States and certain states due to the carry-forward of unutilized net operating losses. In Israel, tax returns remain open to review by the Israel Tax Authority (ITA) for four years from the end of the tax year in which the return was filed. The Company's tax years for periods ending April 30, 2020 and forward are subject to examination by the ITA.

The Company intends to indefinitely reinvest the earnings of its foreign subsidiaries and, therefore, has not recognized deferred taxes on the related outside basis differences.

Note 11. Related Party Transactions

CHAMPIONS ONCOLOGY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Related party transactions include transactions between the Company and its shareholders, management, or affiliates. The following transactions were in the normal course of operations and were measured at the exchange amount, which is the amount of consideration established and agreed to by the parties.

Consulting Services

For fiscal years ended April 30, 2026 and 2025, the Company paid a member of its Board of Directors $0 and $12,000, respectively for consulting services unrelated to his duties as a board member. All of the amounts paid to this related party have been recognized in expense in the period the services were performed within general and administrative expenses in the accompanying consolidated statements of operations.

Note 12. Leases

The Company accounts for its leases under ASC 842. 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 an operating lease ROU asset and operating lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. 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. Variable lease expenses, if any, are recorded when incurred. The Company has elected to apply the short-term lease exemption practical expedient for each class of underlying assets and excludes short-term leases having initial terms of 12 months or less. The Company recognizes rent expense on a straight-line basis over the lease term for these short-term leases. The Company has determined that no material embedded leases exist. Under ASC 842, the Company determines if an arrangement is a lease at inception. ROU assets and liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

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 expenses totaled $1.8 million for the years ended April 30, 2026 and 2025.

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 $78,000 and $75,000 of rent expense relative to this lease for fiscal 2026 and 2025, 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 and the operating commencement date was August 11, 2017. The lease was amended to expand the premises and extend the expiration date in March 2020 and again in December 2020. This lease expires in February 2029. The Company recognized $1.7 million of rent expense for both fiscal 2026 and 2025.

•VIA LEONE XIII, 14, Milan, Italy, which consists of laboratory and office space where the Company conducted operations related to its flow cytometry service offerings. The Company executed the lease in November 2022. The lease was set to expire October 31, 2028. During the three months ended October 31, 2025, the Company exercised its right to terminate the lease early. The lease terminated April 30, 2026 and the Company is not currently utilizing a physical site in Italy. As part of this lease modification, the Company recorded a reduction to its right of use asset related to this lease of $108,000 during the year ended April 30, 2026. The Company also recorded a reduction to the current and non-current portions of the related operating lease liabilities of $16,000 and $101,000, respectively, during the year. These reductions resulted in the recording of a gain on lease termination of $9,000. The Company recognized $50,000 of rent expense associated with this lease in Italy for both fiscal 2026 and 2025.

Refer to Note 4, Property and Equipment, for more information on financing leases.

Note 13. Subsequent Events

On June 5, 2026, subsequent to the 2026 fiscal year-end balance sheet date, the Company executed an amendment to its existing operating lease for its office and lab space located in Rockville, MD , extending the lease term through March 31, 2037. The amendment will be accounted for as a lease modification in accordance with ASC 842 in the first quarter of fiscal 2027.

Based on its preliminary assessment, the Company expects the lease modification to increase its operating lease right-of-use assets and its operating lease liabilities by approximately $6.3 million. The amendment is also expected to increases the Company's future contractual minimum lease payment obligations by approximately $16.9 million over the remaining lease term through March 31, 2037. These amounts are preliminary and may change upon completion of the Company's detailed lease accounting analysis.
