SUMMARY

ABOUT US

We were incorporated April 24, 2012 under the laws of the State of Nevada. We intend to engage primarily in the development of regenerative medical applications which we intend to license, develop internally or acquire outright from other entities up to the point of successful completion of Phase I and or Phase II clinical trials after which we would either attempt to sell or license those developed applications or, alternatively, advance the application further to Phase III clinical trials. The primary factor to be considered by us in arriving at a decision to advance an application further to Phase III clinical trials would be a greater than anticipated indication of efficacy seen in Phase I trials.

The Company has the following therapies in development:

HemaXellarate : HemaXellarate is a cellular composition of autologous stromal vascular fraction derived from adipose tissue. HemaXellarate contains endothelial progenitor cells as well as mesenchymal stem cells. It is believed by the Company that once re-infused into the patient, the patient’s bone marrow will regenerate and begin to function normally. On February 5, 2013 Regen filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (“FDA”) to initiate a Phase I clinical trial assessing HemaXellerate in patients with drug-refractory aplastic anemia. The Phase I clinical trial is intended to determine safety and potential efficacy of intravenously administered autologous SVF cells in patients with severe, immune suppressive refractory aplastic anemia with the primary endpoints of safety and feasibility and secondary endpoints of efficacy as determined by patients having complete response, partial response or relapse.On December 10, 2015 Regen was informed by the United States Food and Drug Administration that Regen has satisfactorily addressed all clinical hold issues related to Regen’s Investigational New Drug Application for HemaXellerate and may initiate a Phase I clinical trial assessing HemaXellerate in patients with drug-refractory aplastic anemia. The Phase I clinical trial is intended to determine safety and potential efficacy of intravenously administered autologous stromal vascular fraction (SVF) cells in patients with severe, immune suppressive refractory aplastic anemia with the primary endpoints of safety and feasibility and secondary endpoints of efficacy as determined by patients having complete response, partial response or relapse. The Company has submitted a request to the United States Food and Drug Administration to grant Orphan Drug Designation to HemaXellerate for the treatment of Immune Suppressant Refractory Aplastic Anemia.

dCellVax: dCellVax is comprised of autologous dendritic cells which have been treated with an siRNA inhibitor of indoleamine-2,3-dioxygenase (IDO), an immunosuppressive enzyme. The Company believes that by inhibiting this enzyme in these dendritic cells, the patient’s cells can now attack cancers, particularly breast cancer.

tCellVax: Immune cells are removed from the patient, treated with siRNA to inhibit NR2F6 and the cells re-infused to the patient. The Company believes that once the inhibitor protein is blocked, the immune system will be very activated and kill tumors. siRNA is a double-stranded RNA molecule that is non-coding and is a powerful tool in drug targeting and therapeutics development as it is used to modulate gene expression through transcriptional or translational repression. The NR2F6 nuclear receptor has been identified as a potentially very important immune cell inhibitor (an immune checkpoint) and cancer stem cell differentiator.

DiffronC: This drug is intended to use our proprietary siRNA in vivo to inhibit cancer growth and activate T cells. The siRNA targets NR2F6. T cells are part of the immune system and develop from stem cells in the bone marrow.

DuraCar: DuraCar is comprised of CAR-T cells which have been treated with an shRNA targeting the gene NR2F6. By inhibiting NR2F6, we expect our DuraCar cells to have greater efficacy and persistence than conventional CAR-T cells and create a new, optimal way to manufacture CAR-T cells. We are currently in pre-clinical testing of this drug. Chimeric antigen receptor T cells ( CAR-T cells) are T cells that have been genetically engineered to produce an artificial T cell receptor for use in immunotherapy. Chimeric antigen receptors are receptor proteins that have been engineered to give T cells the new ability to target a specific antigen.

Small molecule: We have identified and patented a series of small molecules which can both activate and inhibit NR2F6. We are currently in pre-clinical testing of these drugs.

None of the abovementioned statements regarding any of our products in development are intended to be a prediction or conclusion of efficacy. No clinical trials on our product candidates have commenced so no conclusions of efficacy can be made.

As of December 31, 2025 we have not licensed any existing therapies which may be marketed.

The Company has entered into license agreements with Zander Therapeutics, Inc. ( an entity under common control) and Oncology Pharma Inc. ( an unrelated entity).

Both Zander and Oncology Pharma, Inc. will be required to obtain approval from the United States Food and Drug Administration (“FDA”) in order to market any Licensed Product which may be developed within the United States and no assurance may be given that such approval would be granted.

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below as well as other information provided to you in this Offering Circular, including information in the section of this document entitled “CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS”. If any of the following risks actually occur, our business, financial condition or results of operations could be materially adversely affected, the value of our common stock could decline, and you may lose all or part of your investment. The following discussion and analysis should be read in conjunction with the other financial information and consolidated financial statements and related notes appearing in this Offering Circular.

RISK FACTORS

Risks Related to our Business:

THERE IS SUBSTANTIAL DOUBT ABOUT THE COMPANY’S ABILITY TO CONTINUE AS A GOING CONCERN.

The Company generated net losses of $21,691,620 during the period from April 24, 2012 (inception) through September 30, 2025. This condition raises substantial doubt about the Company’s ability to continue as a going concern. The Company’s continuation as a going concern is dependent on its ability to meet its obligations, to obtain additional financing as may be required and ultimately to attain profitability. Because obtaining investment capital is not certain, we may not have the funds necessary to continue our operations. Our ability to meet our operating needs depends in large part on our ability to secure third party financing. We cannot provide any assurances that we will be able to obtain sufficient financing.

THE COMPANY DOES NOT CURRENTLY OWN OR OPERATE ANY LABORATORY OR MANUFACTURING FACILITIES, THE COMPANY CAN PROVIDE NO ASSURANCE THAT THE USAGE OF SUCH FACILITIES CAN BE OBTAINED ON TERMS FAVORABLE TO THE COMPANY

The Company does not currently own or operate any laboratory or manufacturing facilities. As a result, we plan to outsource certain functions, tests and services to Contract Research Organizations (“CROs”) and collaborators as well as outsourcing manufacturing to collaborators and/or contract manufacturers. We also plan to engage CROs to run all aspects of preclinical studies and clinical trials on our behalf. There is no assurance that such individuals or organizations will be able to provide the functions, tests, or services as agreed upon or in a quality fashion or on terms favorable to the Company. Any failure to do so could cause us to suffer significant delays in the development of our products.

WE ARE IN THE EARLY STAGES OF DEVELOPING OUR PRODUCTS, THE EFFECTIVENESS OF WHICH ARE UNPROVEN.

The Company is currently in the early stage of developing its products. No assurance can be given that the Company’s products will prove effective for their intended purpose or otherwise that any of our work will result in any commercially viable product.

COMPETITORS WITH MORE RESOURCES MAY FORCE US OUT OF BUSINESS.

In the event that we have sufficient financial resources, we anticipate that we will compete with many large and well-established companies. Aggressive pricing by our competitors or the entrance of new competitors into our markets could reduce our revenue and profit margins and otherwise result in significant financial losses that could result in insolvency or bankruptcy.

WE MAY NOT BE ABLE TO ATTAIN PROFITABILITY WITHOUT SIGNIFICANT ADDITIONAL FINANCING WHICH MAY BE UNAVAILABLE.

To date we have funded our operations with minimal financial resources, and we have not generated sufficient cash from operations to be profitable. Unless we are successful in generating sufficient revenues to finance operations as a going concern while also achieving profitability and positive cash flow, we may experience liquidity and solvency problems. Such liquidity and solvency problems may force us to cease operations if additional financing is not available.

WE MAY NOT BE ABLE TO RAISE ADDITIONAL CAPITAL ON ACCEPTABLE TERMS.

We are aware that our business may require significant capital in the future each year and for many years even if we can implement our business plans. Even if we are successful in implementing our business plan, any person who acquires our Common Stock or our Preferred Stock will likely suffer significant and immediate dilution or otherwise become subordinate to the rights and claims of creditors. In addition, any financing that we obtain may not be available on terms favorable to us, or at all. Our ability to obtain additional funding will be subject to various factors, including market conditions, our operating performance, lender and investor sentiment and our ability to incur additional debt or equity financing in compliance with other contractual restrictions which may arise. These factors may make the timing, amount, terms and conditions of additional financings unattractive. Our inability to raise capital could impede our growth. Any person who acquires our securities should be prepared to lose all of their investment.

WE RELY ON HIGHLY SKILLED PERSONNEL AND, IF WE ARE UNABLE TO RETAIN OR MOTIVATE KEY PERSONNEL OR HIRE QUALIFIED PERSONNEL, WE MAY NOT BE ABLE TO GROW EFFECTIVELY.

Our performance largely depends on the talents and efforts of highly skilled individuals. Competition in our industry for qualified employees is intense. In addition, our compensation arrangements may not always be successful in attracting new employees and retaining and motivating our existing employees. Our continued ability to compete effectively depends on our ability to attract new employees and to retain and motivate our existing employees.

THE COMPANY DOES NOT MAINTAIN CERTAIN INSURANCE, INCLUDING ERRORS AND OMISSIONS INSURANCE.

The Company has limited capital and, therefore, does not currently have a policy of insurance against liabilities arising out of the negligence of its officers and directors and/or deficiencies in any of its business operations. Even assuming that the Company obtained insurance, there is no assurance that such insurance coverage would be adequate to satisfy any potential claims made against the Company, its officers and directors, or its business operations or products. Any such liability which might arise could be substantial and may exceed the assets of the Company.

WE MAY HAVE DIFFICULTY IN ATTRACTING AND RETAINING MANAGEMENT AND OUTSIDE INDEPENDENT MEMBERS TO OUR BOARD OF DIRECTORS AS A RESULT OF THEIR CONCERNS RELATING TO THEIR INCREASED PERSONAL EXPOSURE TO LAWSUITS AND STOCKHOLDER CLAIMS BY VIRTUE OF HOLDING THESE POSITIONS IN A PUBLICLY-HELD COMPANY.

We are aware that directors and management of publicly-traded corporations are increasingly concerned with the extent of their personal exposure to lawsuits and stockholder claims, as well as governmental and creditor claims which may be made against them, particularly in view of recent changes in securities laws imposing additional duties, obligations and liabilities on management and directors. Due to these perceived risks, directors and management are also becoming increasingly concerned with the availability of directors’ and officers’ liability insurance to pay on a timely basis the costs incurred in defending such claims. We currently do not carry directors’ and officers’ liability insurance. Directors’ and officers’ liability insurance has recently become much more expensive and difficult to obtain. If we are unable to provide directors’ and officers’ liability insurance at affordable rates or at all, it may become increasingly more difficult to attract and retain qualified outside directors to serve on our board of directors. We may lose potential independent board members and management candidates to other companies that have greater directors’ and officers’ liability insurance to insure them from liability or to companies that have revenues or have received greater funding to date which can offer more lucrative compensation packages. The fees of directors are also rising in response to their increased duties, obligations and liabilities as well as increased exposure to such risks. As a company that is in the early stages of development and which has limited resources, we will have a more difficult time attracting and retaining management and outside independent directors than a more established company due to these enhanced duties, obligations and liabilities.

IN THE FUTURE WE MAY BE SUBJECT TO INTELLECTUAL PROPERTY RIGHTS CLAIMS, WHICH ARE COSTLY TO DEFEND, COULD REQUIRE US TO PAY DAMAGES AND COULD LIMIT OUR ABILITY TO SELL SOME OF OUR PRODUCTS.

Although we have not been subject to any intellectual property litigation or infringement claims, we may be in the future, which could cause us to incur significant expenses to defend such claims, divert management’s attention or prevent us from manufacturing, selling or using some aspect of our products. If we chose or are forced to settle such claims, we may be required to pay for a license to certain rights, paying royalties on both a retrospective and prospective basis, and/or cease our manufacturing and sale of certain products that are alleged to be infringing. Future infringement claims against us by third parties may adversely impact our business, financial condition and results of operations.

WE MAY BE SUBJECT TO VARIOUS FORMS OF LITIGATION INCLUDING, BUT NOT LIMITED TO, CLASS ACTION LAWSUITS, WHICH ARE COSTLY TO DEFEND, COULD REQUIRE US TO PAY DAMAGES AND COULD LIMIT OUR ABILITY TO SELL SOME OF OUR PRODUCTS.

Companies have been the target of class action lawsuits and other proceedings alleging, among other things, violations of federal and state workplace and employment laws. Proceedings of this nature, if successful, could result in our payment of substantial damages.

Our results of operations may be adversely affected by legal or governmental proceedings brought by or on behalf of employees or consumers. In recent years, a number of companies, have been subject to lawsuits, including class action lawsuits, alleging violations of federal and state law. A number of these lawsuits have resulted in the payment of substantial awards by the defendants. Although we are not currently a party to any class action lawsuits, we could incur substantial damages and expenses resulting from lawsuits, which would increase the cost of operating the business and decrease the cash available for other uses.

WE ARE SUBJECT TO NUMEROUS LAWS AND REGULATIONS, FAILURE TO COMPLY WITH THOSE LAWS AND REGULATIONS MAY ADVERSELY IMPACT OUR BUSINESS.

Products we are currently developing and which may be developed by us would be highly regulated. We currently have no products approved for sale and we cannot guarantee that we will ever have marketable products. The development of a product candidate and issues relating to its approval and marketing are subject to extensive regulation by the Food and Drug Administration (FDA) in the United States and regulatory authorities in other countries, with regulations differing from country to country. We are not permitted to market our product candidates in the United States until we receive approval of a New Drug Application (NDA) or a Biologic License Application (BLA), as applicable, from the FDA.

In the United States, NDAs and BLAs must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired indication. NDAs and BLAs must also include significant information regarding the chemistry, manufacturing and controls for the product. Obtaining approval of a NDA or BLA is a lengthy, expensive and uncertain process, and we may not be successful in obtaining approval. Regulators of other jurisdictions, such as the European Medicines Agency (EMA) , a European Union agency for the evaluation of medicinal products, have their own procedures for approval of product candidates. Even in the event that a product is approved, the FDA or the EMA, as the case may be, may limit the indications for which the product may be marketed, require extensive warnings on the product labeling or require expensive and time-consuming clinical trials or reporting as conditions of approval. Regulatory authorities in countries outside of the United States and Europe also have requirements for approval of drug candidates with which we must comply prior to marketing in those countries. Obtaining regulatory approval for marketing of a product candidate in one country does not ensure that we will be able to obtain regulatory approval in any other country.

NO ASSURANCE CAN BE GIVEN THAT ANY PRODUCT IN DEVELOPMENT OR WHICH MAY BE PUT INTO DEVELOPMENT WILL SUCCESSFULLY COMPLETE ANY CLINICAL TRIALS.

Clinical trials involving new drugs and biologics are commonly classified into three phases. Each phase of the drug approval process is treated as a separate clinical trial and the drug-development process usually advances through all four phases over many years. Each phase exposes greater number of subjects to the drug and each phase builds on existing safety and efficacy information. Phase 1 trials are designed to assess the safety and tolerability of a drug or biologic. Phase II trials are designed to assess how well the drug or biologic works, as well as to continue Phase I safety assessments in a larger group of volunteers and patients. Phase III trials are aimed at being the definitive assessment of how effective the drug or biologic is, in comparison with current treatment and to provide an adequate basis for physician labeling. If the drug or biologic successfully passes through Phases I, II, and III, it will usually be approved by the national regulatory authority for use in the general population.

The Company’s plan is to engage primarily in the development of regenerative medical applications up to the point of successful completion of Phase I and or Phase II clinical trials after which we would either attempt to sell or license those developed applications or, alternatively, advance the application further to Phase III clinical trials.

We have yet to complete a successful clinical trial of any product under development and no assurance can be made that any product under development will successfully complete a clinical trial.

THE COMPANY CAN PROVIDE NO ASSURANCE THAT IT WILL BE ABLE TO SELL OR LICENSE ANY PRODUCT UNDER DEVELOPMENT OR WHICH WE MAY DEVELOPIN THE FUTURE.

The Company’s current plans include the development of regenerative medical applications up to the point of successful completion of Phase I and/ or Phase II clinical trials after which we would either attempt to sell or license those developed applications or, alternatively, advance the application further to Phase III clinical trials. We can provide no assurance that the Company will be able to sell or license any product or that, if such product is sold or licensed, such sale or license will be on terms favorable to the Company.

WE HAVE NOT OBTAINED PATENT PROTECTION FOR MUCH OF OUR INTELLECTUAL PROPERTY.

The Company has not obtained patent protection on much of its intellectual property. Although the Company plans on attempting to obtain patents on its products and services, there can be no assurance that the Company can obtain effective protection against unauthorized duplication or the introduction of substantially similar products.

LIABILITY OF DIRECTORS FOR BREACH OF DUTY OF CARE IS LIMITED. OUR BYLAWS INDEMNIFY MEMBERS OF OUR BOARD OF DIRECTORS, OUR OFFICERS, EMPLOYEES, AND AGENTS AND PERSONS WHO FORMERLY HELD SUCH POSITIONS, AND THE LEGAL REPRESENTATIVES OF ANY OF THEM, TO THE FULLEST EXTENT LEGALLY PERMISSIBLE UNDER THE GENERAL CORPORATION LAW OF THE STATE OF NEVADA AGAINST ANY OR ALL EXPENSE, LIABILITY AND LOSS REASONABLY INCURRED IN DEFENDING A CIVIL OR CRIMINAL ACTION, SUIT OR PROCEEDING TO WHICH ANY SUCH PERSON SHALL HAVE BECOME SUBJECT BY REASON OF HIS HAVING HELD SUCH A POSITION OR HAVING ALLEGEDLY TAKEN OR OMITTED TO TAKE ANY ACTION IN CONNECTION WITH SUCH POSITION.

According to Nevada law (NRS 78.138(7)), all Nevada corporations limit the liability of directors and officers, including acts not in good faith. Our stockholders’ ability to recover damages for fiduciary breaches may be reduced by this statute. In addition our Bylaws indemnify members of the board of directors, our officers, employees, and agents and persons who formerly held such positions, and the legal representatives of any of them, to the fullest extent legally permissible under the general corporation law of the state of Nevada against any or all expense, liability and loss reasonably incurred in defending a civil or criminal action, suit or proceeding to which any such person shall have become subject by reason of his having held such a position or having allegedly taken or omitted to take any action in connection with such position.

DEPENDENCE ON DAVID R. KOOS, WITHOUT WHOSE SERVICES COMPANY BUSINESS OPERATIONS COULD CEASE.

At this time, the sole officer and director of the Company is David R. Koos, who is wholly responsible for the development and execution of our business. Mr. Koos is not party to an employment agreement with us. If Mr. Koos should choose to leave us for any reason before we have hired additional personnel our operations may fail. Even if we are able to find additional personnel, it is uncertain whether we could find qualified management who could develop our business along the lines described herein or would be willing to work for compensation the Company could afford. Without such management, the Company could be forced to cease operations and investors in our common stock or other securities could lose their entire investment. David Koos is not party to an employment agreement with the Company.

LIABILITY OF DIRECTORS FOR BREACH OF DUTY OF CARE IS LIMITED.

According to Nevada law (NRS 78.138(7)), all Nevada corporations limit the liability of directors and officers, including acts not in good faith. Our stockholders’ ability to recover damages for fiduciary breaches may be reduced by this statute.

EVENTS OUTSIDE OF OUR CONTROL, INCLUDING PUBLIC HEALTH CRISES SUCH AS THE COVID-19 PANDEMIC, COULD NEGATIVELY AFFECT OUR BUSINESS AND OUR OPERATING RESULTS.

A public health crisis such as the COVID-19 pandemic may cause us to experience disruptions that could severely impact our business including interruptions in preclinical studies due to restricted or limited operations at laboratory facilities, interruption or delays in the operations of the FDA or other regulatory authorities, which may impact review and approval timelines and interruption of, or delays in receiving, supplies for productions of our product candidates from our third party suppliers due to staffing shortages, production slowdowns or stoppages and disruptions in delivery system.

While we are not currently conducting any clinical trials in the event of a public health crisis during a time when we are in the process of conducting one or more clinical trials such trials may be adversely impacted due to:

● delays or difficulties in enrolling patients in our clinical trials;

● delays or difficulties in clinical trial site activities, including difficulties in recruiting clinical trial staff;

● diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;

● interruption of key clinical trial activities, such as clinical trial site data monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others or interruption of clinical trial subject visits and study procedures (i.e., those that are deemed non-essential), which may impact the integrity of subject data and clinical study endpoints.

Risks Related to an Investment in Our Common Stock

WE DO NOT PLANT TO PAY CASH DIVIDENDS IN THE FORESEEABLE FUTURE.

We currently intend to retain all future earnings for use in the operation and expansion of our business. We do not intend to pay any cash dividends in the foreseeable future. Unless we pay dividends, our stockholders will not be able to receive a return on their shares unless they sell them. There is no assurance that stockholders will be able to sell shares when desired or that any continuous and liquid trading market will develop or, if it does develop, that it will be sustained for any period of time and at a level that will allow a stockholder an opportunity to sell any shares of our common stock in any amount at any time.

OUR COMMON STOCK IS QUOTED ON THE OTCID BASIC MARKET WHICH MAY HAVE AN UNFAVORABLE IMPACT ON OUR STOCK PRICE AND LIQUIDITY.

Our common stock is quoted on the OTCID Basic Market. The OTCID Basic Market is a significantly more limited market than the New York Stock Exchange or NASDAQ system. The quotation of our shares on the OTCID Basic Market may result in a less liquid market available for existing and potential stockholders to trade shares of our common stock, could depress the trading price of our common stock and could have a long-term adverse impact on our ability to raise capital in the future.

PENNY STOCK” RULES MAY MAKE BUYING OR SELLING OUR COMMON STOCK DIFFICULT.

Trading in our securities is subject to the “penny stock” rules. The SEC has adopted regulations that generally define a penny stock to be any equity security that has a market price of less than $5.00 per share, subject to certain exceptions. These rules require that any broker-dealer who recommends our securities to persons other than prior customers and accredited investors, must, prior to the sale, make a special written suitability determination for the purchaser and receive the purchaser’s written agreement to execute the transaction. Unless an exception is available, the regulations require the delivery, prior to any transaction involving a penny stock, of a disclosure schedule explaining the penny stock market and the risks associated with trading in the penny stock market. In addition, broker-dealers must disclose commissions payable to both the broker-dealer and the registered representative and current quotations for the securities they offer. The additional burdens imposed upon broker-dealers by such requirements may discourage broker-dealers from effecting transactions in our securities, which could severely limit the market price and liquidity of our securities. Broker-dealers who sell penny stocks to certain types of investors are required to comply with the Commission’s regulations concerning the transfer of penny stocks. These regulations require broker- dealers to:

These requirements may restrict the ability of broker-dealers to sell our common stock and may affect your ability to resell our common stock.

CONCENTRATED CONTROL RISKS; SHAREHOLDERS COULD BE UNABLE TO CONTROL OR INFLUENCE KEY CORPORATE ACTIONS OR EFFECT CHANGES IN THE COMPANY’S BOARD OF DIRECTORS OR MANAGEMENT

Our sole officer and director, David R. Koos, has voting power over 27,436,799 shares of our common stock, 413,281 of our Series A Preferred stock, 34 shares of our Series AA Preferred Stock , 7,667 shares of our Series M Preferred Stock and 15,007 shares of our Series NC Preferred stock representing approximately 27% of the voting control of the Company as of November 10, 2025. Mr. Koos therefore has significant influence with regard to many major decisions regarding our affairs. In addition, due to Mr. Koos’ voting power, investors in this offering will have limited control over matters requiring approval by our security holders, including the election of directors, whether or not to sell all or substantially all of our assets and for what consideration and whether or not to authorize more stock for issuance or otherwise amend our charter or bylaws.

BECAUSE WE HAVE ELECTED TO DEFER COMPLIANCE WITH NEW OR REVISED ACCOUNTING STANDARDS PURSUANT TO SECTION 102(b)(1) OF THE JOBS ACT OUR FINANCIAL STATEMENT DISCLOSURE MAY NOT BE COMPARABLE TO SIMILAR COMPANIES.

We have elected to use the extended transition period for complying with new or revised accounting standards under Section 102(b)(1) of the JOBS Act. This allows us to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As a result of our election, our financial statements may not be comparable to companies that comply with public company effective dates..

LIKELIHOOD OF IMMEDIATE AND SUBSTANTIAL DILUTION.

We anticipate that we may need to raise additional capital to implement our business plan. At present we have not had any definitive discussions with any venture capital, angel investors, FINRA-registered broker dealers, or other persons regarding the extent of their interest in investing into the Company. Since we are an early-stage company with no track record of generating revenues, positive cash flow, or profitability, there can be no guarantee that we will raise the additional capital that we anticipate that we will need to raise or, if we are successful in raising any such additional capital that we can do so on a reasonable and timely basis, in sufficient amounts and on terms that are reasonable in light of our present circumstances. For these and other reasons, any person who acquires our Common Stock is likely to incur immediate and substantial dilution with respect to the book value of the Company’s common stock offered hereby.

FUTURE ISSUANCE OF COMMON STOCK RELATED TO CONVERTIBLE NOTES PAYABLE AND ACCRUED INTEREST ON CONVERTIBLE NOTES PAYABLE MAY HAVE A DILUTING FACTOR ON EXISTING AND FUTURE SHAREHOLDERS.

As of September 30, 2025 the Company has outstanding an aggregate of approximately $1,477,139 of convertible debt and accrued interest on convertible debt. Of that aggregate amount approximately $1,213,142 is convertible into common or Series A preferred shares of the Company at various discounts from the market price of the Company’s publicly traded shares. It is the Company’s belief that as of September 30, 2025 shares issuable to the holders of approximately $964,695 of combined convertible debt and accrued interest on convertible debt convertible into common or Series A preferred shares of the Company at various discounts may be resold pursuant to the safe harbor provisions of Rule 144. It is also the Company’s belief that as of September 30, 2025 a total of approximately $1,218,691 of combined convertible debt and accrued interest on convertible debt may be resold pursuant to the safe harbor provisions of Rule 144

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS

The Company’s common stock is a “penny stock,” as defined in Rule 3a51-1 under the Exchange Act. The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document that provides information about penny stocks and the nature and level of risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its sales person in the transaction, and monthly account statements showing the market value of each penny stock held in the customer’s account. In addition, the penny stock rules require that the broker-dealer, not otherwise exempt from such rules, must make a special written determination that the penny stock is suitable for the purchaser and receive the purchaser’s written agreement to the transaction. These disclosure rules have the effect of reducing the level of trading activity in the secondary market for a stock that becomes subject to the penny stock rules. So long as the common stock of the Company is subject to the penny stock rules, it may be more difficult to sell common stock of the Company.

Currently, except as may be provided by applicable laws, there are no contractual or other restrictions on our ability to pay dividends if we were to decide to declare and pay them.

Director Independence

Audit Committee and Audit Committee Financial Expert

The members of the Company’s board of Directors may not be considered independent. The Company is not a “listed company” under Securities and Exchange Commission (“SEC”) rules and is therefore not required to have an audit committee comprised of independent directors. The Company does not currently have an audit committee, however, for certain purposes of the rules and regulations of the SEC and in accordance with the Sarbanes-Oxley Act of 2002, the Company’s Board of Directors is deemed to be its audit committee and as such functions as an audit committee and performs some of the same functions as an audit committee including: (1) selection and oversight of our independent accountant; (2) establishing procedures for the receipt, retention and treatment of complaints regarding accounting, internal controls and auditing matters; and (3) engaging outside advisors. The Board of Directors has determined that its member is able to read and understand fundamental financial statements and has substantial business experience that results in that member’s financial sophistication. Accordingly, the Board of Directors believes that its member has the sufficient knowledge and experience necessary to fulfill the duties and obligations that an audit committee would have.

Nominating and Compensation Committees

The Company does not have standing nominating or compensation committees, or committees performing similar functions. The board of directors believes that it is not necessary to have a compensation committee at this time because the functions of such committee are adequately performed by the board of directors. The board of directors also is of the view that it is appropriate for the Company not to have a standing nominating committee because the board of directors has performed and will perform adequately the functions of a nominating committee. The Company is not a “listed company” under SEC rules and is therefore not required to have a compensation committee or a nominating committee.

Shareholder Communications

There has not been any defined policy or procedure requirements for stockholders to submit recommendations or nomination for directors. There are no specific, minimum qualifications that the board of directors believes must be met by a candidate recommended by the board of directors. Currently, the entire board of directors decides on nominees, on the recommendation of any member of the board of directors followed by the board’s review of the candidates’ resumes and interview of candidates. Based on the information gathered, the board of directors then makes a decision on whether to recommend the candidates as nominees for director. The Company does not pay any fee to any third party or parties to identify or evaluate or assist in identifying or evaluating potential nominee.

Because the Chief Executive Officer of the Company is also the Chairman of the Board of Directors of the Company, the Board of Directors has determined not to adopt a formal methodology for communications from shareholders on the belief that any communication would be brought to the Board of Directors’ attention by virtue of the co-extensive capacities of the Chairman of the Board of Directors.

HemaXellerate is a patient-specific composition of cells that have been demonstrated to repair damaged bone marrow and stimulate production of blood cells based in previous animal studies. The initial application of HemaXellerate will be the treatment of severe aplastic anemia which is characterized by immune-mediated bone marrow hypoplasia (underdevelopment or incomplete development of a tissue) and pancytopenia (reduction in the number of blood cells and platelets).

Adipose tissue is collected from the patient and processed in order to separate, extract and isolate Stromal Vascular Fraction (SVF), a mix of various cell types including mesenchymal stem cells and endothelial cells. Mesenchymal stem cells are connective tissue cells that can differentiate into a variety of cell types and endothelial cells are the cells that line the interior surface of blood vessels and lymphatic vessels and which play a vital role in angiogenesis (the physiological process through which new blood vessels form from pre-existing vessels).

The isolated SVF is then intravenously administered to the patient. The Company believes that the isolated SVF will generate growth factors with the ability to repair damaged hematopoietic stem cells. Hematopoietic stem cells are immature cells that can develop into all types of blood cells, including white blood cells, red blood cells, and platelets. Hematopoietic stem cells are found in the peripheral blood and the bone marrow.

On February 5, 2013 Regen filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (“FDA”) to initiate a Phase I clinical trial assessing HemaXellerate in patients with drug-refractory aplastic anemia. The Phase I clinical trial is intended to determine safety and potential efficacy of intravenously administered autologous SVF cells in patients with severe, immune suppressive refractory aplastic anemia with the primary endpoints of safety and feasibility and secondary endpoints of efficacy as determined by patients having complete response, partial response or relapse.

Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a previously unapproved drug or biologic intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States. Generally, if a product with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a seven year period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug for that time period. The sponsor of the product would also be entitled to a United States federal tax credit equal to 50% of clinical investigation expenses as well as exemptions from certain fees.

The Company believes that this application of HemaXellerate qualifies for Orphan designation under the Orphan Drug Act due to the fact that aplastic anemia is a rare disease with prevalence in the United States of less than 200,000. The Company has submitted a request to the United States Food and Drug Administration to grant Orphan Drug Designation to HemaXellerate for the treatment of Immune Suppressant Refractory Aplastic Anemia .

On December 10, 2015 Regen was informed by the United States Food and Drug Administration that Regen has satisfactorily addressed all clinical hold issues related to Regen’s Investigational New Drug Application for HemaXellerate and may initiate a Phase I clinical trial assessing HemaXellerate in patients with drug-refractory aplastic anemia. The Phase I clinical trial is intended to determine safety and potential efficacy of intravenously administered autologous stromal vascular fraction (SVF) cells in patients with severe, immune suppressive refractory aplastic anemia with the primary endpoints of safety and feasibility and secondary endpoints of efficacy as determined by patients having complete response, partial response or relapse.

dCellVax is intended to be a therapy whereby dendritic cells of the cancer patient are harvested from the body, treated with siRNA that has the ability to block the dendritic cell from expressing indoleamine 2,3-dioxygenase (“IDO”) and subsequently reimplanted in the cancer patient.

The dendritic cells that are treated with the IDO-blocking RNA become resistant to the influence of tumor cells which produce factors which cause the dendritic cell to express the IDO. Expression of IDO in the dendritic cell halts the dendritic cell from activating T cells and causes the dendritic cell to suppress T cells. T lymphocytes (‘T cells”) are a lymphocyte that play a central role in the human immune system’s attempt to eradicate tumors. The Company has filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (“FDA”) to initiate a Phase I/II clinical trial assessing safety with signals of efficacy of the dCellVax gene-silenced dendritic cell immunotherapy for treating breast cancer. The proposed trial will recruit 10 patients with metastatic breast cancer and will involve 4 monthly injections of the dCellVax gene-silenced dendritic cell therapy. The trial is anticipated to last one year, with tumor assessment before therapy and at 6 and 12 months.

On May 12, 2021 the “Company executed a consulting agreement with Biotech Research Group Corporation, an FDA Specialist Group and Global Regulatory and Scientific Experts, for the purpose of review and guidance with regard to the planned reinstatement of the Company’s inactive Investigational New Drug applications (INDs) #15376 (HemaXellerate) and #16200 (dCellVax) filed with the United States Food and Drug Administration (“FDA”). The securing of the services to be provided to the Company pursuant to this consulting agreement marks the first step taken by the Company with regard to activating the Company’s currently inactive applications to initiate clinical trials.

tCellVax is intended to be a therapy where immune cells are removed from the cancer patient, treated with siRNA which inhibits NR2F6 and the cells re-infused to the patient. NR2F6 normally acts as a brake on the ability of various immune cells from being activated. The immune cells that are treated with the NR2F6-blocking siRNA become highly activated and can efficiently kill tumors.. The Company has filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (“FDA”) to initiate a Phase I clinical trial assessing safety and feasibility of the dCellVax gene-silenced immune cell immunotherapy for treating patients with solid tumors that are metastatic or not able to be removed surgically. The proposed trial will recruit 25 patients with metastatic cancer and will involve 3 monthly injections of the dCellVax gene-silenced dendritic cell therapy. The trial is anticipated to last one year, with tumor assessment before therapy and at 6 and 12 months.

DiffronC: NR2F6 is a transcription factor that is present in many cells in the body, including immune cells but also highly expressed in certain solid tumors. NR2F6 normally acts as a brake on the ability of various immune cells from being activated and also allows tumor cells to keep growing. The Company has developed a proprietary drug that is based on shRNA technology, which prevents NR2F6 from being expressed. By inhibiting the expression of NR2F6, immune cells that are treated with the NR2F6-blocking shRNA become highly activated and can efficiently kill tumors and tumors that have NR2F6 suppressed begin to differentiate.. We are currently in pre-clinical testing of this drug to optimize its delivery in vivo.

DuraCar: DuraCar is a new cellular therapy being developed by the Company. It is comprised of CAR-T cells which contain an shRNA targeting the gene NR2F6. CAR-T cells are T cells (the lymphoid cells of the body that kill tumors) isolated from a cancer patient that have been modified by expressing a chimeric antigen receptor (CAR) which is specific for the patient’s tumor. These CAR-T cells are then re-infused back into the patient. The CAR-T cells then home in directly on the tumor because they have been given the tumor-specific address via the CAR. While CAR-T cells are very effective in treating leukemias, they are not effective at treating most solid tumors. The reason for this is believed to be that the CAR-T cells are “turned-off” by the physical environment surround solid tumors. By inhibiting NR2F6, we expect our DuraCar cells to have greater efficacy and persistence than conventional CAR-T cells and create a new, optimal way to manufacture CAR-T cells. We are currently in pre-clinical testing of this drug.

Experiments performed on behalf of the Company by two unrelated contract research organizations (CROs) found that T cells which express the chimeric antigen receptor (CAR) construct targeting CD19 and expressing siRNA for NR2F6 had high expression levels of NR2F6 mRNA. NR2F6 is considered an immune checkpoint and thus increasing its activity is likely to lead to immune suppression which may be utilized in the development of therapies for the treatment of autoimmune disorders.

Small molecule: We have identified and patented a series of small molecules which can both activate and inhibit NR2F6. NR2F6 normally acts as a brake on the ability of various immune cells from being activated and also allows tumor cells to keep growing. By inhibiting the function of NR2F6 using small molecules, immune cells that are treated with the NR2F6-blocking agents, similar to using the shRNA approach, should become highly activated and efficiently kill tumors. In addition, tumors that have NR2F6 blocked by using these small molecules should begin to differentiate. Conversely, activating NR2F6 is expected to suppress the immune system. This ability to suppress the immune system can be very useful for treating autoimmune disorders. We are currently in pre-clinical testing of these drugs.

None of the abovementioned statements regarding any of our products in development are intended to be a prediction or conclusion of efficacy. No clinical trials on our product candidates have commenced so no conclusions of efficacy can be made.

The Company believes that this application of HemaXellerate qualifies for Orphan designation under the Orphan Drug Act due to the fact that aplastic anemia is a rare disease with prevalence in the United States of less than 200,000 and intends to apply to the FDA for Orphan designation for HemaXellerate.

On December 10, 2015 Regen was informed by the United States Food and Drug Administration that Regen has satisfactorily addressed all clinical hold issues related to Regen’s Investigational New Drug Application for HemaXellerate and may initiate a Phase I clinical trial assessing HemaXellerate in patients with drug-refractory aplastic anemia.

The costs to perform this Phase I clinical trial is estimated to be approximately $550,000 and it is estimated to take 1 year to complete.

The company is developing another cell therapy product termed dCellVax. dCellVax is intended to be a therapy whereby dendritic cells of the cancer patient are harvested from the body, treated with siRNA that has the ability to block the dendritic cell from expressing indoleamine 2,3-dioxygenase (“IDO”) and subsequently reimplanted in the cancer patient.

The dendritic cells that are treated with the IDO-blocking RNA become resistant to the influence of tumor cells which produce factors which cause the dendritic cell to express the IDO.

The Company has filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (“FDA”) to initiate a Phase I/II clinical trial assessing safety with signals of efficacy of the dCellVax gene-silenced dendritic cell immunotherapy for treating breast cancer. The proposed trial will recruit 10 patients with metastatic breast cancer and will involve 4 monthly injections of the dCellVax gene-silenced dendritic cell therapy. The trial is anticipated to cost $5,000,000 and last one year, with tumor assessment before therapy and at 6 and 12 months.

On May 12, 2021 the “Company executed a consulting agreement with Biotech Research Group Corporation, an FDA Specialist Group and Global Regulatory and Scientific Experts, for the purpose of review and guidance with regard to the planned reinstatement of the Company’s inactive Investigational New Drug applications (INDs) #15376 (HemaXellerate) and #16200 (dCellVax) filed with the United States Food and Drug Administration (“FDA”). The securing of the services to be provided to the Company pursuant to this consulting agreement marks the first step taken by the Company with regard to activating the Company’s currently inactive applications to initiate clinical trials.

Another cell therapy that focuses on a different mechanism of action than dCellVax is tCellVax. tCellVax is intended to be a therapy in which immune cells are removed from the cancer patient, treated with siRNA which inhibits NR2F6 and the cells re-infused to the patient. NR2F6 normally acts as a brake on the ability of various immune cells from being activated. The immune cells that are treated with the NR2F6-blocking siRNA become highly activated and can efficiently kill tumors.

We are currently in pre-clinical testing of this drug to optimize its delivery in vivo. The two main risks associated with this drug development plan is that the NR2F6 siRNA is not effective at inhibiting NR2F6 expression or that this inhibition will not result in immune cells with enhanced tumoricidal activity.

DuraCar: DuraCar is a new cellular therapy being developed by the Company. It is comprised of CAR-T cells which contain an shRNA targeting the gene NR2F6. CAR-T cells are T cells (the lymphoid cells of the body that kill tumors) isolated from a cancer patient that have been modified by expressing a chimeric antigen receptor (CAR) which is specific for the patient’s tumor.

By inhibiting NR2F6, we expect our DuraCar cells to have greater efficacy and persistence than conventional CAR-T cells and create a new, optimal way to manufacture CAR-T cells. We have engaged two contract research organizations to advance our pre-clinical testing of this drug. Pre-clinical testing includes design and construction of the relevant plasmids, efficient transfection of T cells, assessment of the expression levels of the siRNA directed at NR2F6 and measurement of its effectiveness at inhibition of NR2F6 expression. Then, these cells will be analyzed for enhanced tumor-killing activity. The two main risks associated with this drug development plan is that the NR2F6 siRNA is not effective at inhibiting NR2F6 expression or that this inhibition will not result in a T cell with enhanced tumoricidal activity. Successful completion of these pre-clinical experiments will significantly de-risk the project.

Experiments performed on behalf of the Company by two unrelated contract research organizations (CROs) found that T cells which express the chimeric antigen receptor (CAR) construct targeting CD19 and expressing siRNA for NR2F6 had high expression levels of NR2F6 mRNA.

Distribution methods of the products or services:

It is anticipated that Regen and /or KCL will enter into licensing and/or sublicensing agreements with outside entities in order that Regen and/or KCL may obtain royalty income on the products and services which it may develop and commercialize.

Competitive business conditions and Regen’s competitive position in the industry and methods of competition

We have yet to achieve significant revenues or profits. The pharmaceutical and biologics industries in which we intend to compete are highly competitive and characterized by rapid technological advancement. Many of our competitors have greater resources than we do.

We intend to be competitive by utilizing the services and advice of individuals that we believe have expertise in their field in order that we can concentrate our resources on projects in which products and services in which we have the greatest potential to secure a competitive advantage may be developed and commercialized. The Company’s intent is to enter into nonemployee consulting agreements with individuals who we believe have a high level of expertise in their professional fields and who have agreed to provide counsel and assistance to us in (a) determining the viability of proposed projects (b) obtaining financing for projects and (c) obtaining the resources required to initiate and complete a project in the most cost effective and rapid manner.

Sources and availability of raw materials and the names of principal suppliers

The supplies and materials required to conduct our operations are available through a wide variety of sources and may be obtained through a wide variety of sources.

Need for any government approval of principal products or services, effect of existing or probable governmental regulations on the business.

The US Food and Drug Administration (“FDA”) and foreign regulatory authorities will regulate our proposed products as drugs or biologics, , depending upon such factors as the use to which the product will be put, the chemical composition, and the interaction of the product on the human body. In the United States, products that are intended to be introduced into the body will generally be regulated as drugs, while tissues and cells intended for transplant into the human body will be generally be regulated as biologics.

Our domestic human drug and biological products will be subject to rigorous FDA review and approval procedures. After testing in animals, an Investigational New Drug Application (“IND”) must be filed with the FDA to obtain authorization for human testing. Extensive clinical testing, which is generally done in three phases, must then be undertaken at a hospital or medical center to demonstrate optimal use, safety, and efficacy of each product in humans.

Phase I

Phase 1 trials are designed to assess the safety (pharmacovigilance), tolerability, pharmacokinetics, and pharmacodynamics of a drug. These trials are often conducted in an inpatient clinic, where the subject can be observed by full-time staff. The subject who receives the drug is usually observed until several half-lives of the drug have passed. Phase I trials normally include dose-ranging, also called dose escalation, studies so that the appropriate dose for therapeutic use can be found. The tested range of doses usually are a fraction of the dose that causes harm in animal testing and involve a small group of healthy volunteers. However, there are some circumstances when real patients are used, such as patients who have end-stage disease and lack other treatment options.

Phase II

Phase II trials are designed to assess how well the drug or biologic works, as well as to continue Phase I safety assessments in a larger group of volunteers and patients. Phase II trials are performed on larger groups.

Phase III

Phase III trials are aimed at being the definitive assessment of how effective the product is in comparison with current best standard treatment and to provide an adequate basis for physician labeling. Phase III trials may also be conducted for the purposes of (i) “label expansion” (to show the product works for additional types of patients/diseases beyond the original use for which the drug was approved for marketing or (ii) to obtain additional safety data, or to support marketing claims for the product.

On occasion Phase IV (Post Approval) trials may be required by the FDA. Phase IV trials involve the safety surveillance (pharmacovigilance) and ongoing technical support of a drug after it receives permission to be sold. The safety surveillance is designed to detect any rare or long-term adverse effects over a much larger patient population and longer time period than was possible during the Phase I-III clinical trials.

All phases, must be undertaken at a hospital or medical center to demonstrate optimal use, safety, and efficacy of each product in humans. Each clinical study is conducted under the auspices of an independent Institutional Review Board (“IRB”). The IRB will consider, among other things, ethical factors, the safety of human subjects, and the possible liability of the institution. The time and expense required to perform this clinical testing can far exceed the time and expense of the research and development initially required to create the product. No action can be taken to market any therapeutic product in the United States until an appropriate New Drug Application (“NDA”) or Biologic License Application (“BLA”) or has been approved by the FDA. FDA regulations also restrict the export of therapeutic products for clinical use prior to NDA or BLA approval.

Even after initial FDA approval has been obtained, further studies may be required to provide additional data on safety or to gain approval for the use of a product as a treatment for clinical indications other than those initially targeted. In addition, use of these products during testing and after marketing could reveal side effects that could delay, impede, or prevent FDA marketing approval, resulting in FDA-ordered product recall, or in FDA-imposed limitations on permissible.

The FDA regulates the manufacturing process of pharmaceutical products, and human tissue and cell products, requiring that they be produced in compliance with Current Good Manufacturing Practices (“cGMP”). The FDA also regulates the content of advertisements used to market pharmaceutical products. Generally, claims made in advertisements concerning the safety and efficacy of a product, or any advantages of a product over another product, must be supported by clinical data filed as part of an NDA or an amendment to an NDA, and statements regarding the use of a product must be consistent with the FDA approved labeling and dosage information for that product.

Sales of drugs and biologics outside the United States are subject to foreign regulatory requirements that vary widely from country to country. Even if FDA approval has been obtained, approval of a product by comparable regulatory authorities of foreign countries must be obtained prior to the commencement of marketing the product in those countries. The time required to obtain such approval may be longer or shorter than that required for FDA approval

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

‘The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to provide information necessary to understand our audited consolidated financial statements for the fiscal years ended September 30, 2025 and 2024 and highlight certain other information which, in the opinion of management, will enhance a reader’s understanding of our financial condition, changes in financial condition and results of operations. In particular, the discussion is intended to provide an analysis of significant trends and material changes in our financial position and the operating results of our business during the year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. This discussion should be read in conjunction with our consolidated financial statements for the fiscal years ended September 30, 2025 and 2024 and related notes included elsewhere in this 10-K. These historical financial statements may not be indicative of our future performance. This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains numerous forward-looking statements, all of which are based on our current expectations and could be affected by the uncertainties and risks. Throughout this report, the terms “our,” “we,” “us,” and the “Company” refer to Regen Biopharma, Inc. and its subsidiaries.

In some cases, forward-looking statements may be identified by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “expect,” “objective,” “plan,” “potential,” “seek,” “grow,” “target,” “if,” and similar expressions intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations, objectives, and financial needs.

Results of Operations

Revenues

Revenues from continuing operations were $236,561 for the fiscal year ended September 30, 2025 and $236,560 for the same period ended 2024. $110,001 and $110,000 of revenue from related parties recognized during the twelve months ended September 30 2025 and 2024 consisted of anniversary expense receivable pursuant to a license granted by the Company to Zander Therapeutics, Inc. $126,560 and $126,560 of revenue recognized during the twelve months ended September 30, 2025 and 2024 were recognized pursuant to licenses granted to Oncology Pharma, Inc.

Operating Expenses

Operating Expense were $575,101 for the twelve months ended September 30, 2025 and $653,781 for the same period ended 2024. The primarily operating expense for 2025 consists of $ 398,263 of Consulting & Professional expenses and $90,000 in rent. In the previous year Consulting and Professional fees expenditure were $363,391. During the period ended 2024 research and development expenses amounted to $153,565 constituting the second largest expense recognized during that period.

Other Income

For the twelve months ended September 30 2025, the Company reported a net other expense of $(935,962) whereas in the same period ended 2024 the Company reported the net other expense of $(251,034). Net other expense was primarily driven by the recognition of a Derivative Expense in of $(675,528) in 2025. For the period ended June 30, 2025 the Company also recognized higher interest and amortization expenses as compared to the period ended 2024.

Net Loss

The Company recognized an Operating Loss of $338,540 during the fiscal year ended September 30, 2025 whereas the Company recognized an Operating Loss of $417,221 for the same period ended 2024. The reduction in operating loss is primarily attributable to a reduction in all expense categories other than General and Administrative expenses and rent incurred during the period ended 2025 as compared to the period ended in 2025.

Net Loss is $1,274,502 for the fiscal year ended September 30, 2025 as opposed to a Net Loss of $668,255 for the same period ended 2024. The difference is primarily attributable to the recognition by the Company of a Derivative Loss of $675,528 recognized in the period ended in 2025.

Liquidity and Capital Resources

Operating Activities

Net cash used in operating activities for the twelve months ended September 30, 2025 was $383,591, compared to $751,536, for the same period ended 2024. The decrease in cash used in operating activities is primarily attributable to decreased operating expenses incurred by the Company during the fiscal year ended 2025 as compared to the same period ended 2024.

Financing Activities

Net cash generated by financing activities for the twelve months ended September 30, 2025 was $452,430 which consisted of proceeds from notes payables and sale of common stock.

Liquidity & Capital Resources Outlook

As of September 30, 2025, the Company had cash of $ 69,555 and a net working deficit of approximately $6.2 million.

The Company has incurred and expects to continue to incur significant professional costs to remain as a publicly traded company and it has incurred and expects to continue incur significant research & development cost for products development.

The accompanying financial statements have been prepared as if the Company will continue as a going concern. The Company has incurred significant operating losses and negative cash flows from operations since inception. As of September 30, 2025, the Company had cash of approximately $69,555 and an accumulated deficit of approximately $21 million. The Company has incurred recurring losses, experienced recurring negative operating cash flows, and requires significant cash resources to execute its business plans. The Company is dependent on obtaining additional working capital funding from the sale of equity and/or debt securities and/or governmental or private grants in order to continue to execute its development plans and continue operations. Without additional funding, there is substantial doubt about the Company’s ability to continue as a going concern for the twelve months from the date of these financial statements.

Contractual Obligations

As of September 30, 2025 the Company was not party to any binding agreements which would commit Regen to any material capital expenditures.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K promulgated under the Exchange Act.

FINANCIAL STATEMENTS

Report of Independent Registered Public Accounting Firm

To the Board of Directors

and Stockholders of Regen Biopharma, Inc. and Subsidiary

Opinion on the Consolidated Financial Statements

We have audited the accompanying balance sheets of Regen Biopharma, Inc. (the “Company”) as of September 30, 2025 and 2024, the related statement of operations, stockholders’ equity (deficit), and cash flows for 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 financial position of the Company as of September 30, 2025 and 2024, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States.

Substantial Doubt about the Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company’s significant operating losses raise substantial doubt about its ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

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 Matters

The critical audit matter communicated below is a matter 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. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

● Going Concern – As discussed in Note 2 to the financial statements, the Company has a going concern due to negative working capital and losses from operations which raises substantial doubt about its ability to continue as a going concern. Auditing management’s evaluation of a going concern can be a significant judgment given the fact that the Company uses management estimates on future revenues and expenses, which are difficult to substantiate. To evaluate the appropriateness of the going concern, we examined and evaluated the financial information along with management’s plans to mitigate the going concern and management’s disclosure on going concern.
