NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1 - Business Organization, Nature of Operations, Risks and Uncertainties and Basis of Presentation
Organization and Operations
Cell Source, Inc. (“Cell Source”, “CSI” or the “Company”) is a Nevada corporation formed on June 6, 2012 that is the parent company of Cell Source Limited (“CSL”), a wholly owned subsidiary which was founded in Israel in 2011 in order to commercialize a suite of inventions relating to certain cancer treatments. The Company is a biotechnology company focused on developing cell therapy treatments based on the management of immune tolerance. The Company’s lead prospective product is its patented Veto Cell immune system management technology, which is an immune tolerance biotechnology that enables the selective blocking of immune responses. CSL’s Veto Cell immune system management technology is based on technologies patented, owned, and licensed to CSL by Yeda Research and Development Company Limited, an Israeli corporation (“Yeda”) (see Note 8, Commitments and Contingencies). The Company’s target indications include: lymphoma, leukemia and multiple myeloma through the facilitation of safer and more accessible stem cell (e.g. bone marrow) transplantation acceptance, treatment of end stage kidney disease and other non-malignant organ diseases through improved organ transplantation (broadened donor pool, reduced dependence on post-transplant anti-rejection therapy) and ultimately treating a variety of cancers and non-malignant diseases. The Company’s current research and development activities are primarily conducted through sponsored research agreements with The University of Texas MD Anderson Cancer Center (see Note 8, Commitments and Contingencies).
Risks and Uncertainties
On February 24, 2022, Russian military forces invaded Ukraine, and the length, impact, and outcome of the ongoing war in Ukraine is highly unpredictable. On October 7, 2023, Hamas terrorists infiltrated Israel’s border with the Gaza Strip and conducted a series of attacks on civilian and military targets. Hamas has also launched extensive rocket attacks on Israeli population and industrial centers located along Israel’s border with the Gaza Strip and in other areas within the State of Israel. These attacks have resulted in extensive deaths, injuries and kidnapping. Following the attack, Israel’s security cabinet declared war against Hamas and a military campaign against these terrorist organizations commenced in parallel to their continued rocket and terror attacks. Although there is currently a cease fire in the Israel-Hamas conflict, no assurance can be given that the cease fire will continue. On February 28, 2026, United States and Israeli forces conducted a series of attacks in Iran, and Iran responded by launching retaliatory attacks on Israel and United States military bases in the Middle East. The intensity and duration of the United States/Israel war against Iran is difficult to predict. As a result of the Russia-Ukraine, Israel-Hamas and United States/Israel-Iran wars and other geopolitical and macroeconomic events, the global credit and financial markets have experienced volatility and disruptions.
As of March 31, 2025 and through the date of this filing, the Company considered the impact of these wars and other geopolitical and macroeconomic events on its business and operational assumptions and estimates and determined there were no material adverse impacts on the Company’s consolidated results of operations and financial position.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, such statements include all adjustments (consisting only of normal recurring items) which are considered necessary for a fair presentation of the condensed consolidated financial position of the Company as of March 31, 2025 and the condensed consolidated results of its operations and cash flows for the three months ended March 31, 2025 and 2024. The results of operations for the three months ended March 31, 2025 are not necessarily indicative of the operating results for the full year ending December 31, 2025 or any other period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related disclosures of the Company as of December 31, 2024 and for the year then ended which were included in the Company’s Annual Report on Form 10-K that was filed with the Securities and Exchange Commission (“SEC”) on April 6, 2026.
Note 2 - Going Concern and Management Plans
During
the three months ended March 31, 2025, the Company did not generate any revenues, had a net loss of approximately $
The
Company is currently funding its operations on a month-to-month basis. While there can be no assurance that it will be successful, the
Company is in active negotiations to raise additional capital. The Company’s primary sources of operating funds since inception
have been equity and debt financings. Management’s plans include continued efforts to raise additional capital through debt and
equity financings. There is no assurance that these funds will be sufficient to enable the Company to fully complete its development
activities or attain profitable operations. If the Company is unable to obtain such additional financing on a timely basis or, notwithstanding
any request the Company may make, if the Company’s debt holders do not agree to convert their notes into equity or extend the maturity
dates of their notes, the Company may have to curtail its development, marketing and promotional activities, which would have a material
adverse effect on the Company’s business, financial condition and results of operations, and ultimately the Company could be forced
to discontinue its operations and liquidate. Subsequent to March 31, 2025 and as more fully described in Note 10, Subsequent Events,
the Company received aggregate proceeds of approximately $

The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the financial statements do not necessarily purport to represent realizable or settlement values. The condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.
Note 3 - Summary of Significant Accounting Policies
There have been no material changes to the Company’s significant accounting policies included in the Annual Report on Form 10-K for the year ended December 31, 2024, except as disclosed herein.
Reclassifications
Certain prior year amounts in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net loss, total assets, total liabilities, shareholders’ equity, or cash flows from operations. Management has evaluated these reclassifications and determined that they are not material, individually or in the aggregate, to the condensed consolidated financial statements taken as a whole.
The Company computes basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding for the period and excludes the effects of any potentially dilutive securities. Diluted earnings per share includes the dilution that would occur upon the exercise or conversion of all dilutive securities into common stock using the “treasury stock” and/or “if converted” methods, as applicable.

Recently Adopted Accounting Standards
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this update address investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. This update also includes certain other amendments to improve the effectiveness of income tax disclosures. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024 with early adoption permitted. The Company adopted ASU No. 2023-09 as of January 1, 2025 on a prospective basis and its adoption did not have a material impact on the Company’s condensed consolidated financial statements.

Note 4 - Fair Value
The following table provides a summary of the changes in fair value, including net transfers in and/or out, of all Level 3 liabilities measured at fair value on a recurring basis using unobservable inputs during the three months ended March 31, 2025 and 2024:
| Warrant | Accrued | Derivative | ||||||||||||||
| Liabilities | Compensation | Liabilities | Total | |||||||||||||
| Balance - January 1, 2025 | $ | $ | $ | $ | ||||||||||||
| Issuance of warrants and conversion option | ||||||||||||||||
| Change in fair value | ( | ) | ( | ) | ( | ) | ( | ) | ||||||||
| Balance - March 31, 2025 | $ | $ | $ | $ | ||||||||||||
| Warrant | Accrued | Derivative | ||||||||||||||
| Liabilities | Compensation | Liabilities | Total | |||||||||||||
| Balance - January 1, 2024 | $ | $ | $ | $ | ||||||||||||
| Accrual of warrant obligation | ||||||||||||||||
| Issuance of warrants and conversion option | ||||||||||||||||
| Common stock issued in satisfaction of accrued compensation | ( | ) | ( | ) | ||||||||||||
| Change in fair value | ( | ) | ( | ) | ( | ) | ( | ) | ||||||||
| Balance - March 31, 2024 | $ | $ | $ | $ | ||||||||||||
Financial assets and liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. The Company’s Level 3 liabilities shown in the above table consist of warrants with “down-round protection”, as the Company is unable to determine if it will have sufficient authorized common stock to settle such arrangements, warrants deemed to be derivative liabilities according to the Company’s sequencing policy in accordance with ASC 815-40-35-12, the embedded conversion options within its convertible notes payable, the fair value of the Company’s obligation to issue penalty warrants (which is classified within warrant liabilities and warrant liabilities – related party on the condensed consolidated balance sheets), and an accrued obligation to issue common stock (which is a component of accrued compensation).
In applying the Black-Scholes option pricing model utilized in the valuation of Level 3 liabilities, the Company used the following approximate assumptions:
| For the Three Months Ended | ||||||||
| March 31, | ||||||||
| 2025 | 2024 | |||||||
| Risk-free interest rate | % - | % | % - | % | ||||
| Expected term (years) | - | - | ||||||
| Expected volatility | % | % | ||||||
| Expected dividends | % | % | ||||||
The expected term used is the contractual life of the instrument being valued. Since the Company’s stock has not been publicly traded for a sufficiently long period of time or with significant volume, the Company is utilizing an expected volatility based on a review of the historical volatilities, over a period of time, equivalent to the expected life of the instrument being valued, of similarly positioned public companies within its industry. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued.
As
of March 31, 2025 and December 31, 2024, the Company had an obligation to issue shares of common stock to service providers that

Overview
We are a cell therapy company focused on immunotherapy. Since our inception, we have been involved with the development of proprietary immune system management technology licensed from Yeda Research & Development Company Limited (“Yeda”), the commercial arm of the Weizmann Institute. We have since shifted the focus of our research and development efforts to MD Anderson.
This technology addresses one of the most fundamental challenges within human immunology: how to tune the immune response such that it tolerates selected desirable foreign cells, but continues to attack all other (undesirable) targets. In simpler terms, a number of potentially life-saving treatments have limited effectiveness today because the patient’s immune system rejects them. For example, while HSCT – hematopoietic stem cell transplantation (e.g. bone marrow transplantation) has become a preferred therapeutic approach for treating blood cell cancer, most patients do not have a matched family donor. Although matched unrelated donors and cord blood can each provide an option for such patients, haploidentical stem cell transplants (sourced from partially mismatched family members) are rapidly gaining favor as a treatment of choice. This is still a risky and difficult procedure primarily because of potential conflicts between host (recipient) and donor immune systems and also due to viral infections that often follow even successful HSCT while the compromised new immune system works to reconstitute itself by using the transplanted stem cells. Today, rejection is partially overcome using aggressive immune suppression treatments that leave the patient exposed to many dangers by compromising their immune system.
The unique advantage of Cell Source technology lies in the ability to induce sustained tolerance of transplanted cells (or organs) by the recipient’s immune system in a setting that requires only mild immune suppression, while avoiding the most common post-transplant complications. The scientific term for the result of successfully inducing such tolerance in a transplantation setting is chimerism, where the recipient’s immune system tolerates the co-existence of the (genetically different) donor type and host type cells. Attaining sustained chimerism is an important prerequisite to achieving the intrinsic GvL (graft versus leukemia) effect of HSCT and supporting the reconstitution of normal hematopoiesis (generation of blood cells, including those that protect healthy patients from cancer) in blood cancer patients. Preclinical data and initial clinical data show that Cell Source’s Veto Cell technology can provide superior results in allogeneic (donor-derived) HSCT by allowing for haploidentical stem cell transplants under a mild conditioning regimen, while avoiding the most common post-transplant complications. Combining this with CAR (Chimeric Antigen Receptor) T cell therapy as a unified VETO CAR-T treatment, we will be able to treat patients in relapse as well as those in remission and use the cancer killing power of CAR-T to protect the patient while their immune system fully reconstitutes, thus providing an end-to-end solution for blood cancer treatment by potentially delivering a fundamentally safer and more effective allogeneic HSCT: prevention of relapse; avoidance of GvHD; prevention of viral infections; and enhanced persistence of GvL effect. This means that the majority of patients will be able to find a donor, and will have access to a potentially safer procedure with higher long term survival rates than what either donor-derived HSCT or autologous CAR-T each on their own currently provide.
The ability to induce permanent chimerism (and thus sustained tolerance) in patients – which allows the transplantation to overcome rejection without having to compromise the rest of the immune system – may open the door to effective treatment of a number of severe medical conditions, in addition to blood cancers, which are characterized by this need. These include:
| ● | The broader set of cancers, including solid tumors, that can potentially be treated effectively using genetically modified cells such as CAR-T cell therapy, but also face efficacy and economic constraints due to limited persistence based on immune system issues (i.e., the need to be able to safely and efficiently deliver allogeneic CAR-T therapy). Inducing sustained tolerance to CAR-T cells may bring reduced cost and increased efficacy by allowing for off-the-shelf (vs. patient-derived) treatments with more persistent cancer killing capability. | |
| ● | Organ failure and transplantation. A variety of conditions can be treated by the transplantation of vital organs. However, transplantation is limited both by the insufficient supply of available donor organs and the need for lifelong, daily anti-rejection treatments post-transplant. Haploidentical organ transplants, with sustained chimerism, have the potential to make life saving transplants accessible to the majority of patients, with the prospect of improved life quality and expectancy. | |
| ● | Non-malignant hematological conditions (such as type one diabetes and sickle cell anemia) which could, in many cases, also be more effectively treated by stem cell transplantation if the procedure could be made safer and more accessible by inducing sustained tolerance in the stem cell transplant recipient. |
Human Capital Resources
Other than our Chief Executive Officer, we currently do not have any full-time employees, but retain the services of independent contractors/consultants on a contract-employment basis.

Recent Developments
Preclinical Results and Clinical Results
After two years of intensive collaboration with Professor Zelig Eshhar, the inventor of CAR-T cell therapy, preclinical data confirmed that Veto Cells can markedly extend persistence of genetically modified T cells from the same donor and that genetically modified Veto Cells can effectively inhibit tumors expressing an antigen recognized by the transgenic T cell receptor. Furthermore, human Veto Cells transfected with CAR exhibit anti-tumor activity in-vitro without losing their veto activity. These preclinical results have formed the basis of our current development of a clinical protocol for allogeneic VETO CAR-T HSCT combined therapy for blood cancer treatment. Cell Source plans to submit this protocol for approval in 2026. Recent preclinical research has determined that Veto Cells can overcome rejection from both NK (natural killer) cells and T-cells, further enhancing their potential efficacy when used for off-the-shelf CAR-T cell therapy. The Phase 1/2 clinical trial at the University of Texas MD Anderson Cancer Center, using Cell Source’s Anti-viral Veto Cells, has completed the first five treatment cohorts, with 15 patients each receiving a haploidentical HSCT under reduced intensity conditioning with Veto Cells. This trial has thus far shown that there has been no toxicity associated with the Veto Cells, with patients consistently showing successful stem cell engraftment, in the absence of severe GvHD. The study is expected to continue with additional cohorts of patients, using the current treatment protocol.
Private Placement of Series B Convertible Preferred Stock
Beginning in October 2023, the Company entered into subscription agreements with certain accredited investors in a private placement offering. Each unit, which is sold at a price of $7.50 per unit, consists of one (1) share of Series B Convertible Preferred Stock and a five-year warrant to purchase a certain number of shares of common stock at an exercise price of $0.75 per share. For every $100,000 of units acquired, the investor will receive warrants to purchase an aggregate of 150,000 shares of common stock.
From October 2023 through the date of filing, the Company has sold an aggregate of 311,459 units for gross proceeds of $2,336,000 and issued warrants to purchase 3,484,000 shares of the Company’s common stock.
Condensed Consolidated Results of Operations
Three Months Ended March 31, 2025 Compared with the Three Months Ended March 31, 2024
Research and Development
Research and development expense was $515,183 and $356,213 for the three months ended March 31, 2025 and 2024, respectively, an increase of $158,970, or 45%. This increase is primarily due to additional incurred expenses as a result of the execution of new amendments with MD Anderson.
General and Administrative
General and administrative expense, which is associated with external consulting and professional fees, payroll and stock-based compensation expenses, was $483,404 and $781,916 for the three months ended March 31, 2025 and 2024, respectively, a decrease of $298,512, or 38%. The decrease was primarily attributable to decreases in consulting expenses of approximately $30,000, stock-based compensation expense of $200,600 and external expenses of $111,000, due to a decrease in various external services, partially offset by increases in accounting and audit expenses of approximately $46,000, due to increased work performed.
Interest Expense
Interest expense for the three months ended March 31, 2025 and 2024 was $427,237 and $222,814, respectively, an increase of $204,423, or 92%. This increase is primarily associated with an increase in the balance of interest-bearing notes during the three months ended March 31, 2025 as compared to the prior period.
Interest Expense - Amortization of Debt Discount
Amortization of debt discount was $86,637 and $5,956 for the three months ended March 31, 2025 and 2024, respectively, an increase of $80,681, or 1,354%. This increase is primarily associated with an increase in notes payable issued in 2025 compared to the prior year.
Change in Fair Value of Derivative and Warrant Liabilities
During the three months ended March 31, 2025 and 2024, we recognized a gain on the change in fair value of derivative and warrant liabilities of $30,610 and $91,493, respectively, a decrease of $60,883, or 67%. The change in the fair value of our derivative and warrant liabilities during each period was primarily attributable to changes in the fair value of our common stock.
Liquidity and Going Concern
We measure our liquidity in a number of ways, including the following:
| March 31, 2025 | December 31, 2024 | |||||||
| Cash | $ | 1,240 | $ | 74,631 | ||||
| Working capital deficiency | $ | (20,136,035 | ) | $ | (18,537,836 | ) | ||
During the three months ended March 31, 2025, we did not generate any revenues, incurred a net loss of approximately $1,482,000 and used cash in operations of approximately $600,000. As of March 31, 2025, we had a working capital deficiency of approximately $20,136,000 and an accumulated deficit of approximately $47,662,000. As of March 31, 2025 and through the date of this filing, notes payable with principal amounts totaling approximately $6,328,000 and $11,116,000, respectively, were past due. We will continue to incur net operating losses to fund operations. These conditions raise substantial doubt about our ability to continue as a going concern for at least one year from the date these financial statements are issued.
We are currently funding our operations on a month-to-month basis. While there can be no assurance that we will be successful, we are in active negotiations to raise additional capital. Our primary sources of operating funds since inception have been equity and debt financings. Management’s plans include continued efforts to raise additional capital through debt and equity financings. There is no assurance that these funds will be sufficient to enable us to fully complete our development activities or attain profitable operations. If we are unable to obtain such additional financing on a timely basis or, notwithstanding any request we may make, if our debt holders do not agree to convert their notes into equity or extend the maturity dates of their notes, we may have to curtail our development, marketing and promotional activities, which would have a material adverse effect on our business, financial condition and results of operations, and ultimately we could be forced to discontinue our operations and liquidate. Subsequent to March 31, 2025 and as more fully described in Note 10, Subsequent Events, the Company received aggregate proceeds of approximately $2,839,000 from the issuance of notes payable, $310,000 from the issuance of Series B Convertible Preferred Stock and $100,000 from the issuance of Common Stock. The Company will continue to incur net operating losses to fund operations.
| 15 |
There can be no assurances that we will be successful in generating additional cash from equity or debt financings or other sources to be used for operations. Should we not be successful in obtaining the necessary financing to fund our operations, we would need to curtail certain or all operational activities and/or contemplate the sale of our assets, if necessary.
During the three months ended March 31, 2025, our sources and uses of cash were as follows:
Net Cash Used in Operating Activities
We experienced negative cash flows from operating activities for the three months ended March 31, 2025 and 2024 in the amounts of approximately $600,000 and $174,000, respectively. The net cash used in operating activities for the three months ended March 31, 2025 was primarily due to cash used to fund a net loss of approximately $1,482,000, adjusted for net non-cash expenses in the aggregate amount of approximately $211,000, partially offset by $671,000 of net cash provided by changes in the levels of operating assets and liabilities. The net cash used in operating activities for the three months ended March 31, 2024, was primarily due to cash used to fund a net loss of approximately $1,275,000, adjusted for non-cash expenses in the aggregate amount of approximately $215,000, partially offset by $887,000 of net cash provided by changes in the levels of operating assets and liabilities.
Net Cash Provided by Financing Activities
Net cash provided by financing activities for the three months ended March 31, 2025 and 2024 was approximately $527,000 and $152,000, respectively. The net cash provided by financing activities during the three months ended March 31, 2025 was attributable to $150,000 of proceeds from the future issuance of common stock and warrants, $25,000 of proceeds from the future issuance of Series B Convertible Preferred Stock and warrants, approximately $377,000 of net proceeds from the issuance of notes and convertible notes payable, $50,000 of proceeds from subscription receivable, partially offset by the principal repayment of a convertible note payable in the amount of $75,000. The net cash provided by financing activities during the three months ended March 31, 2024 was attributable to $25,000 of proceeds from the issuance of Series B convertible preferred stock and warrants and approximately $147,000 of proceeds from issuance of convertible notes payable to a related party, partially offset by $20,000 of repayment of financing liability.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements.
Critical Accounting Estimates
The preparation of financial statements and related disclosures are in conformity with U.S. GAAP. These accounting principles require us to make estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expense during the periods presented. We believe that the estimates and judgments upon which we rely are reasonable based upon information available to us at the time that we make these estimates and judgments. To the extent that there are material differences between these estimates and actual results, our financial results will be affected. The accounting policies that reflect our more significant estimates and judgments and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results are described below.
We consider an accounting estimate to be critical if: (i) the accounting estimate requires us to make assumptions about matters that were
highly uncertain at the time the accounting estimate was made, and (ii) changes in the estimate that are reasonably likely to occur from
period to period or use of different estimates that we reasonably could have used in the current period, would have a material impact
on our financial condition or results of operations.
There have been no material changes to the Company’s critical accounting estimates since the 2024 Form 10-K.
Valuation of the Company’s Common Stock Price
Because the Company’s common stock historically was not actively traded on a public market, the fair value of the Company’s restricted equity instruments is estimated by management based on observations of the sales prices of both restricted and freely tradable common stock, or instruments convertible into common stock. The Company obtains a third-party valuation of its common stock as of December 31, 2024 and July 1, 2024, and utilizes the December 31, 2024 valuation for management’s estimation of fair value during the three months ended March 31, 2025. The third-party valuation was performed in accordance with regulation of Section 409A of the Internal Revenue Code (“IRC”) as well as FASB ASC Topic 718.
The independent appraisal utilized the market approach, specifically the Backsolve method. The Backsolve method utilizes the economics from a direct transaction in the Company’s securities in determining fair value. The Backsolve method utilizes the Black-Scholes option pricing method (“OPM”) which allocated a probability-weighted present value to the Company’s convertible securities. The following steps were applied under the OPM:
| ● | Establishment of total enterprise or equity value; | |
| ● | Analysis of equity rights for each class of security; | |
| ● | Selection of appropriate model for valuation purposes; | |
| ● | Determination of key valuation inputs; and | |
| ● | Computation of the fair value of the subject security. |
Under the OPM, it was determined the Company’s common stock had a fair value of $0.19 and $0.28 as of December 31, 2024 and July 1, 2024, respectively, which included a discount for lack of marketability of 25%. Furthermore, the independent appraisal determined the Company’s expected volatility was 70% and 75% as of December 31, 2024 and July 1, 2024, respectively, by evaluating historical and implied volatilities of guideline companies.
