Added

We have experienced significant losses since inception and, at December 31, 2025 and 2024, had an accumulated deficit of approximately $132.3 million and $109.6 million, respectively. We expect to incur additional losses in the future and expect the cumulative losses to increase. We expect our operating expenses to increase and it is not likely that our grant revenues will fully fund our clinical programs.

Added

As of December 31, 2025, we had cash and cash equivalents of $4.7 million. As a result of the recently completed private placement financing referenced in Note 14, Subsequent Events, and based on current operating plans, the Company expects that its cash and cash equivalents as of December 31, 2025 plus the $15.9 million in gross proceeds from the private placement will fund operations into the fourth quarter of 2026.

Added

To continue as a going concern, we will need to obtain additional capital, which we will likely obtain through a variety of means, including through public or private equity, debt financings or other sources, including up-front payments and milestone payments from strategic collaborations. There are no assurances that we would be able to raise additional capital or on terms favorable to us. Our recurring losses from operations and negative cash flow raise substantial doubt about our ability to continue as a going concern without sufficient capital resources and we have included an explanatory paragraph in the notes to our financial statements for the year ended December 31, 2025, with respect to this uncertainty. Further, the report of our independent registered public accounting firm with respect to our audited financial statements for the year ended December 31, 2025 included an emphasis of matter paragraph stating that our recurring losses from operations and continued cash outflows from operating activities raised substantial doubt about our ability to continue as a going concern. Our financial statements do not include any adjustments that might result from the outcome of this going concern uncertainty and have been prepared under the assumption that we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

Reworded

We are a clinical stage biotechnology company with a limited operating history upon which you can evaluate our business and prospects. We have no products approved for commercial sale and have not generated any material revenue from product sales. To date, we have devoted substantially all of our resources and efforts to organizing and staffing our company, business planning, building and equipping our research and development laboratories, building and equipping our manufacturing suites, raising capital, acquiring raw materials for manufacturing, investigational product candidate development and manufacturing, securing related intellectual property rights and conducting clinical trials of our Lomecel-B™laromestrocel cellular therapy.therapy investigational product candidate. We have not yet demonstrated our ability to obtain marketing approvals, manufacture a commercial-scale product or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. As a result, it may be more difficult for you to accurately predict our future success or viability than if we had a longer operating history.

Added

As of December 31, 2025, we had $4.7 million in cash and cash equivalents. To date, we have financed our operations primarily through public and private equity financings, grant awards, and fees generated from clinical trial revenue and contract manufacturing services. There are no assurances that we will be able to continue to finance operations through these means, and our inability to generate sufficient revenue in the near term may have an adverse impact on our business, operations and prospects.

Reworded

If the potential of our investigational product candidates to treat diseases is not realized, the value of our technology and our development programs could be significantly reduced.

Reworded

Our team is currently exploring the potential of our investigational product candidates to treat diseases. We have not yet proven in clinical trials that our investigational product candidates will be a safe and effective treatment for any disease or condition. Our investigational product candidates are susceptible to various risks, including undesirable and unintended side effects, unintended immune system responses, inadequate therapeutic efficacy, or other characteristics that may prevent or limit their marketing approval or commercial use. We have not yet completed all of the testing necessary to allow us to make a determination that serious unintended consequences will not occur. If the potential of our investigational product candidates to treat disease is not realized, the value of our technology and our development programs could be significantly reduced. Because our investigational product candidates are based on mesenchymal stem cells,MSCs, any negative developments regarding the therapeutic potential or side effects of our mesenchymal stem cells,MSCs, or regarding scientific and medical knowledge about mesenchymal stem cellsMSCs in general, could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Reworded

We are subject to the risks of failure inherent in the development of investigational product candidates based on new technologies. The novel nature of our investigational product candidates creates significant challenges in regardsregard to product development and optimization, manufacturing, government regulation, third-party reimbursement, and market acceptance. For example, although the FDA has approved several cell therapy products, the FDA has relatively limited experience with regulating these kinds of therapies, and its regulations and policies are still evolving. As a result, the pathway to regulatory approval for our investigational product candidates may be more complex and lengthier.

Reworded

There are no FDA-approved allogeneic, cell-based therapies for Aging-related Frailty, Alzheimer’s disease (AD), or other aging-related conditions, nor HLHSHLHS, pediatric DCM or other cardiac-related indications. This could complicate and delay FDA approval of our investigational product candidate for these indications, or other indications we study or will study.

Reworded

According to the FDA, “Aging-related Frailty” does not have a definition that is acceptable for characterizing the conditions for regulatory purposes, and there are no precedents for regulatory approvals of this indication. This could prevent, complicate and/or delay regulatory approval of our investigational product candidate for these indications to the extent that the Company may continue to pursue this indication.

Reworded

It is possible that the FDA may never recognize “aging” as a disease and may never agree to a definition of “Aging-related Frailty” primarily due to a lack of consensus on the definitions amongst clinicians, researchers and regulators, an insufficient understanding of the underlying pathophysiologic mechanisms that cause any or all of the manifestations, or both. To obtain FDA approval for any indication for the disease states we are studying, we will have to demonstrate, among other things, that our investigational product candidates are safe and effective for that indication in the target population. The results of our clinical trials must be statistically significant, meaning that there must be sufficient data to indicate that it is unlikely the outcome occurred by chance. The FDA will also require us to demonstrate an appropriate dose (i.e., number of cells) and dosing interval for our investigational product candidates, and to identify and define treatment responders, which may require additional clinical trials. As a result, the clinical endpoints, the criteria to measure the intended results of treatment, and the correct dosing for our cell-based therapeutic approaches for "Aging-related Frailty" may be difficult to determine. To the extent we decide to pursue this indication, these challenges may prevent us from developing and commercializing products on a timely or profitable basis, or at all.

Reworded

If we are not able to recruit and retain qualified management and scientific personnel, we may fail in developing our technologies and investigational product candidates.

Reworded

Our investigational product candidates represent new classes of therapy that the marketplace may not understand or accept.

Reworded

Even if we successfully develop and obtain regulatory approval for our investigational product candidates, the market may not understand or accept them. We are developing investigational product candidates that represent novel treatment approaches and will compete with a number of more conventional products and therapies manufactured and marketed by others, including major pharmaceutical companies. The degree of market acceptance of any of our future developed and potential products will depend on a number of factors, including:

Reworded

the clinical safety and effectiveness of our investigational product candidates or future approved products and their perceived advantage over alternative treatment methods;

Reworded

our ability to demonstrate that our cell-based productsinvestigational product candidates have a clinically significant effect, initially for Aging-related Frailty, AD, HLHS, and other disease states for which we may seek marketing approval;

Reworded

adverse events involving our investigational product candidates or candidates of others that are cell based;

Reworded

once approved, our ability to supply a sufficient amount of our products to meet regular and repeated demand in order to develop a core group of medical professionals familiar with and committed to the use of our products; and once approved, the cost of our products and the reimbursement policies of government and third-party payors.

Reworded

If the health carehealthcare community does not accept our investigational product candidates or future approved products for any of the foregoing reasons, or for any other reason, it could affect our sales or have a material adverse effect on our business, financial condition, results of operations, and prospects.

Reworded

Our dependence upon a limited supply of bone marrow donors and biologic growth media may impact our ability to produce sufficient quantities of our investigational product candidates as needed to complete our clinical trials, and if our trials are successful and our productsinvestigational product candidates are approved, to meet product demand.

Reworded

The population of acceptable bone marrow donors is limited to volunteers between the ages of 18 and 45. In addition, potential donors are prescreened for a variety of health conditions and are only allowed to donate bone marrow a total of six times in their lifetime, further limiting the total number of potential donors. The amount of bone marrow donated may be insufficient for us to mass produce our investigational product candidates at a scale sufficient to meet our clinical trial needs or to produce a product, if approved, to meet future commercial demand at an acceptable cost. In addition, the expansion of mesenchymal stem cellsMSCs through our proprietary manufacturing methods utilizes biologic growth media that may be in limited supply. Our investigational product candidates will be inherently more difficult to manufacture at commercial-scale than conventional pharmaceuticals, which are manufactured using precise chemical formulations and operational methods. Cost-effective production at clinical trial or commercial scale quantities may not be achievable.

Reworded

Future government regulation or health concerns may also reduce the number of donors or otherwise limit the amount of bone marrow available to us. If we cannot secure quantities of bone marrow or biologic growth media sufficient to meet the manufacturing demands for our clinical trials, we might not be able to complete our clinical trials and obtain marketing approval for our investigational product candidates. Moreover, even if our clinical trials are successful and we obtain marketing approval for our investigational product candidates, our inability to secure enough bone marrow or biologic growth media to meet commercial product demand could limit our potential revenues.

Reworded

Further, the utilization of donated bone marrow creates the potential for transmission of cancer and communicable disease, including but not limited to human immunodeficiency virus (“HIV”), viral hepatitis, syphilis, Creutzfeldt-Jakob disease, and other viral, fungal, or bacterial pathogens. Although we and our suppliers are required to comply with federal and state regulations intended to prevent communicable disease transmission, we or our suppliers may fail to comply with such regulations. Further, even with compliance, our future products might nevertheless be viewed by the public as being associated with transmission of disease, and a clinical trial subject or patient who contracts an infectious disease might assert that the use of our investigational product candidate or future products resulted in disease transmission, even if the individual became infected through another source.

Reworded

Any actual or alleged transmission of communicable disease could result in clinical trial subject or patient claims, litigation, distraction of management’s attention, increased expenses, and adverse regulatory authority action. Further, any failure in screening, whether by us or other manufacturers of similar products, could adversely affect our reputation, the support we receive from the medical community, and overall demand for our future products. As a result, such actions or claims, whether or not directed at us, could have a material adverse effect on our reputation with our customers and our ability to market our future products, which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Reworded

Our processing and storage facility is located in a region which experiences severe weather, notably hurricanes, from time to time. If this facility in Miami, Florida or the equipment in the facility were to be significantly damaged or destroyed, we could suffer a loss of some, or all of the stored units of our investigational product candidates and it could force us to halt our clinical trial processes. The risk of tropical storm and hurricane activity historically rises on or about June 1st each year and subsides on or about November 30th each year. We have not undertaken a systematic analysis of the potential consequences to our business and financial results from a major hurricane or tornado, flood, fire, earthquake, power loss, terrorist activity or other disasters and do not currently have a recovery plan for such disasters. If we underestimate our insurance needs, we will not have sufficient insurance to cover losses above and beyond the limits on our policies. In addition, we do not carry sufficient insurance to compensate us for actual losses from interruption of our business that may occur, and any losses or damages incurred by us could harm our business. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses.

Reworded

Ethical and other concerns surrounding the use of stem cell therapy or human tissue may negatively affect public perception of us or our future products or investigational product candidates, or may negatively affect regulatory approval of our future products or investigational product candidates, thereby reducing demand for our future products.

Reworded

The commercial success of our investigational product candidates will depend in part on general public acceptance of the use of MSC therapy for the prevention or treatment of human diseases. Although we do not use embryonic stem cells or fetal tissue, the public may not be able to, or may fail to, differentiate our use of adult mesenchymal stem cellsMSCs from the use of embryonic stem cells or fetal tissue by others, which could result in a negative perception of our company or our future products or investigational product candidates, thereby reducing demand, which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Reworded

We may obtain mesenchymal stem cellsMSCs from volunteer adult bone marrow donors from non-profit organizations that collect and process tissue donations. Bone marrow donors receive payment, but ethical concerns have been raised by some about the use of donated human tissue in a for-profit setting, as we are doing. Future adverse events in the field of stem cell therapy, changes in public policy, or changes to the FDA’s regulatory approval framework for these products could also result in greater governmental regulation of our investigational product candidates or future products, and potential regulatory delays relating to their testing or approval.

Reworded

We anticipate that competition in our industry will increase. In addition, the health carehealthcare industry is characterized by rapid technological change, resulting in new product introductions and other technological advancements. Our competitors may develop and market products that render investigational product candidates under development by us now or in the future, or any future products manufactured or marketed by us, non-competitive or otherwise obsolete.

Reworded

Sales of our future products may involve a lengthy sales cycle.

Reworded

Many factors are expected to influence the sales cycle for future products once they are approved. These factors include the future state of the market, the perceived value of our investigational product candidate(s), the evolution of competing technologies, insurance coverage or prior authorization requirements and changes in medical practices. Any of these may adversely affect our sales cycles and the rate of market acceptance of our future approved products.

Removed

As of December 31, 2024, we had $19.2 million in cash and cash equivalents. To date, we have financed our operations primarily through public and private equity financings, grant awards, and fees generated from clinical trial revenue and contract manufacturing services. There are no assurances that we will be able to continue to finance operations through these means, and our inability to generate sufficient revenue in the near term may have an adverse impact on our business, operations and prospects.

Reworded

Global outbreaks of epidemics, pandemics, and other public health risks, such as COVID-19, historically have and may in the future continue to impact countries, communities, supply chains and markets. For example, the COVID-19 pandemic hashistorically impacted our Bahamas Registry Trial business. It is also possible that the COVID-19 pandemic or other public health risks could adversely affect our business, results of operations, financial condition or liquidity in the future. For example, they could impact the timing and enrollment of our collaborators’ planned or ongoing clinical trials, delaying clinical site initiation, regulatory review and the potential receipt of regulatory approvals, payment of milestones under our license agreements and commercialization of one or more of our investigational product candidates, if approved. Epidemics, pandemics, and other public health risks could also disrupt the production capabilities of our contract manufacturing facility. Further, the continued mutation of theviruses, virus causingincluding COVID-19 and other epidemics or pandemics may lead to ongoing illness in our workforce or contracting partners, which may leave individuals unable to work for periods of time. The impact of thesuch epidemics, pandemics, and other public health risks are generally fluid and continue evolve over time, and therefore, we cannot currently predict the extent to which our business, clinical trials, results of operations, financial condition or liquidity would ultimately be impacted. In addition, epidemics, pandemics, and other public health risks could materially and adversely impact our operations due to, among other factors:

Reworded

potential delays in the preparation and submission of applications for regulatory approval of our products,investigational product candidates, as well as potential delays in FDA’s or another regulatory authority's ability to review applications in a timely manner consistent with past practices;

Reworded

Global conditions, dislocations in the financial markets, or continuing inflation could adversely impact our business. In addition, the global macroeconomic environment has been and may continue to be negatively affected by, among other things, instability in global economic markets, increasedevolving U.S. trade tariffs and trade disputes with other countries, instability in the global credit markets, supply chain weaknesses, instability in the geopolitical environment as a result of the RussianRusso-Ukrainian invasion of the Ukraine,War, the Israeli-Palestinian conflict, the withdrawal of the United Kingdom from the European Union, United States military activity in Venezuela and the Caribbean, other political tensions, and foreign governmental debt concerns. Such challenges have caused, and may continue to cause, uncertainty and instability in local economies and in global financial markets, which may adversely affect our business.

Removed

We have experienced significant losses since inception and, at December 31, 2024 and 2023, had an accumulated deficit of approximately $109.6 million and $85.0 million, respectively. We expect to incur additional losses in the future and expect the cumulative losses to increase. We expect our operating expenses to increase and it is not likely that our grant revenues will fully fund our clinical programs.

Removed

As of December 31, 2024, we had cash and cash equivalents of $19.2 million. We currently believe that our cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2025 based on our current operating budget and cash flow forecast. However, as a result of a successful Type C meeting with the U.S. FDA in August 2024 with respect to the HLHS regulatory pathway, we have started to ramp up Biologics License Application (BLA) enabling activities as we currently anticipate a potential filing with the FDA in 2026 if the current ELPIS II trial is successful. Our operating expenses and capital expenditure requirements are expected to accelerate in 2025 as a result of these activities, including CMC (Chemistry, Manufacturing, and Controls) and manufacturing readiness, and there will be a need to increase our current proposed spend and further increase our capital investments. We intend to seek additional financing/capital raises/non-dilutive funding options to support these activities, and current cash projections may be impacted by these ramped up activities and any financing transactions entered into. There can be no assurance we will be able to attain future financing at terms favorable to us or at all. We have based these estimates on assumptions that may prove to be imprecise, and we could utilize our available capital resources sooner than we expect. We currently have no credit facility or committed sources of capital.

Removed

To continue as a going concern, we will need to obtain additional capital, which we will likely obtain through a variety of means, including through public or private equity, debt financings or other sources, including up-front payments and milestone payments from strategic collaborations. There are no assurances that we would be able to raise additional capital or on terms favorable to us. Our recurring losses from operations and negative cash flow raise substantial doubt about our ability to continue as a going concern without sufficient capital resources and we have included an explanatory paragraph in the notes to our financial statements for the year ended December 31, 2024, with respect to this uncertainty. Further, the report of our independent registered public accounting firm with respect to our audited financial statements for the year ended December 31, 2024 included an emphasis of matter paragraph stating that our recurring losses from operations and continued cash outflows from operating activities raised substantial doubt about our ability to continue as a going concern. Our financial statements do not include any adjustments that might result from the outcome of this going concern uncertainty and have been prepared under the assumption that we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

Reworded

The use of our investigational product candidates or future products in individuals may expose us to product liability claims, and we may not be able to obtain adequate product liability insurance coverage.

Reworded

Because of the nature of our investigational product candidates and future products, we face an inherent risk of product liability claims. None of our investigational product candidates have been widely used over an extended period of time, and therefore our safety data are limited. We derive the raw materials for our investigational product candidates from human donor sources, the manufacturing process is complex, and the handling requirements are specific, all of which increase the likelihood of quality failures and subsequent product liability claims. We will need to increase our insurance coverage if and when we receive approval for and begin commercializing our investigational product candidates. We may not be able to obtain or maintain product liability insurance on acceptable terms with adequate coverage or at all. If we are unable to obtain insurance, or if claims against us substantially exceed our coverage, then our business could be adversely impacted. Whether or not we are ultimately successful in any product liability litigation, such litigation either before or after product approval and marketing could consume substantial amounts of our financial and managerial resources and could result in, among other things:

Reworded

recall of future products or termination of clinical trials for our investigational product candidates;

Reworded

FDA withdrawal of marketing approval of future products or suspension or revocation of an IND for aan investigational product candidate;

Reworded

We occasionally provide contract development and manufacturing services to a third-partythird-parties and may, in the future, provide similar services to a limited number of customers that are developing their own cellular therapy treatments. LosingWe anyhave customerexperienced and may in the future experience diminished demand or loss of customers within our contract development and manufacturing services couldoperations, which has in prior periods and may in the future have a significant impact on the income generated from this division of our business. WhetherRevenues from these services are not currently material to our financial results or operations. However, to the extent we areengage developingin andthese manufacturing our product candidates or products or product candidates for our customers,activities, similar regulatory, ethical, supply chain, and demand risks apply.apply whether we are developing and manufacturing our investigational product candidates of future products or investigational product candidates for our customers. Assisting customers in developing a product or investigational product candidate may result in incurring costs and expenses that are not reimbursable by the customer, including, if we are required to obtain regulatory approval that is specific to manufacturing a customer’s product or product candidate. Our success with respect to the contract manufacturing operations of our organization is largely dependent on forces outside of our control as our success in dependent on the success of our customers’ products and product candidates. Our customers may have to overcome the same or similar obstacles that we face in bringing their product to market. We must maintain stringent quality control measures, as failure to do so could lead to manufacturing defective products. Failure to manufacture regulatory compliant products or investigational product candidates could result in recalls, legal liabilities, and impact our relationship with current and future customers. The cell therapy development and manufacturing industry is highly competitive. New companies entering the market could result in pricing pressures, reduced margins, and the loss of market share. Our focus has been and will continue to be on developing our own product candidates, while our competitors may only be focused on manufacturing cell therapies for their customers. Splitting our focus may give other contract manufacturing companies a competitive edge. Furthermore, jurisdictions outside of the United States may have other regulatory requirements that we cannot meet without incurring costs and expenses. Customers looking to obtain regulatory approval in the jurisdictions may engage with competitors that already meet the regulatory requirements of such jurisdictions. Our ability to compete effectively depends on our reputation, quality of service, current technology, regulatory approval, and operational efficiency.

Reworded

If our trade secret and patent position does not adequately protect our investigational product candidates and their uses, others could compete against us more directly, which could harm our business and have a material adverse effect on our business, financial condition and results of operations.

Reworded

Our success depends, in large part, on our ability to obtain and maintain intellectual property protection for our investigational product candidates. The patent position of biotechnology companies is generally highly uncertain, involves complex legal and factual questions, and continues to be the subject of much litigation. Our trade secrets attempt to bridge the gap that threatens patent exclusivity for the protection of products derived from mesenchymal stem cells.MSCs. Our trade secrets also are intended to remain valid and enforceable without regard to limitations such as term restrictions that are imposed on patents. Our trade secrets and know-how are the subject of various license agreements and confidentiality agreements as further discussed below.

Reworded

Our patent applications on MSC technology, in particular, include claims directed to therapeutic uses and kits comprising mesenchymal stem cells.MSCs. Patents with such claims tend to be more vulnerable to challenge by other parties than patents with extremely narrow claims. Also, our pending patent applications may not issue, may issue with substantially narrower claims than currently pending claims, or we may not receive any additional patents. Further, the laws of foreign countries may not protect our intellectual property rights to the same extent as do the laws of the U.S. Our patents might not contain claims that are sufficiently broad to prevent others from practicing our technologies or from competing with us with their own technology in the fields of interest to us.

Reworded

Because of the extensive time required for development, testing, and regulatory review of a potential product, it is possible that, before any of our investigational product candidates can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantages of the patent. To the extent our investigational product candidates based on that technology are not commercialized ahead of this patent expiration, to the extent we have no other patent protection on such products, or to the extent that regulatory or patent extensions are not granted, those future products might not have the robust protection we currently expect to enjoy. The background technologies used in the development of our investigational product candidates are known in the scientific community, and it may be possible to duplicate the methods we use to create our investigational product candidates, which makes us vulnerable to competition, without the ability to exclude others from potentially commercializing a similar product.

Reworded

We are a party to various agreements that give us rights to use specified technologies applicable to research, development, and commercialization of our investigational product candidates. If these agreements are voided or terminated, our product development, research, and commercialization efforts may be altered or delayed. Certain aspects of our technology rely on inventions developed using university or other third-party resources. The universities or third parties may have certain rights, as defined by law or applicable agreements, and may choose to exercise such rights. If we fail to comply with any terms or provisions of these agreements, our rights and our access to the universities’ or third parties’ resources could be terminated. The Exclusive License Agreement with the University of Miami dated November 20, 2014, as amended on December 11, 2017, and on March 3, 2021, and the additional Exclusive License Agreement with the University of Miami, signed and effective as of July 18, 2024, require the Company to pay fees and royalties and to make commercially reasonable efforts to achieve milestones. The University of Miami may terminate the Exclusive License Agreement and the additional Exclusive License Agreement for material breach if the fees and royalties are not paid, or if the milestones are not met and an extension to achieve the milestones is not agreed upon.

Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a substantial amount of litigation involving patents and other intellectual property rights in the biotechnology and pharmaceutical industries. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing our investigational product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our investigational product candidates, methods of making investigational product candidates, and methods of using investigational product candidates may give rise to claims of infringement of the patent rights of others.

Reworded

Third parties may assert that we infringe their patents or are otherwise employing their proprietary technology without authorization and may sue us. We are aware of several U.S. patents held by third parties covering potentially similar or related products and their manufacture and use. Generally, conducting clinical trials and other acts relating to FDA approval are not considered acts of infringement in the U.S. If and when Lomecel-B™laromestrocel mesenchymal stem cellsMSCs are approved by the FDA, third parties may seek to enforce their patents by filing a patent infringement lawsuit against us. Patents issued in the U.S. by law enjoy a presumption of validity that can be rebutted only with evidence that is “clear and convincing,” a heightened standard of proof. We may not be able to prove in litigation that any patent enforced against us is invalid.

Reworded

Additionally, there may be third-party patents of which we are currently unaware with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our investigational product candidates. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our investigational product candidates may infringe. Some of those patent applications may not yet be available for public inspection. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of our investigational product candidates, constructs or molecules used in or formed during the manufacturing process, or any final product itself, the holders of any such patents may be able to block our ability to commercialize the investigational product candidates unless we obtain a license under the applicable patents, or until such patents expire or they are finally determined to be held not infringed, unpatentable, invalid or unenforceable. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use, including combination therapy or patient selection methods, the holders of any such patent may be able to block our ability to develop and commercialize the investigational product candidate unless we obtained a license or until such patent expires or is finally determined to be held not infringed, unpatentable, invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms or at all. If we are unable to obtain a necessary license to a third-party patent on commercially reasonable terms, or at all, our ability to commercialize our investigational product candidates may be impaired or delayed, which could in turn significantly harm our business.

Reworded

Parties making claims against us may seek and obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our investigational product candidates. They might seek an exclusion order from the International Trade Commission to prevent import of our investigational product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business and may impact our reputation. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties or redesign our infringing investigational product candidates or future products, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our investigational product candidates. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize our investigational product candidates, which could harm our business significantly.

Reworded

We may become involved in lawsuits to protect or enforce our patents or the patents of our collaborators or licensors, which could be expensive and time consuming.time-consuming.

Reworded

The biotechnology industry, including our fields of therapeutic interest, is highly competitive and subject to significant and rapid technological change. Accordingly, our success may depend, in part, on our ability to respond quickly to such change through the development and introduction of new products. Our ability to compete successfully against currently existing and future alternatives to our investigational product candidates and systems and competitors who compete directly with us in the biopharmaceutical industry may depend, in part, on our ability to attract and retain skilled scientific and research personnel, develop technologically superior products, develop competitively priced products, obtain patent or other required regulatory approvals for our products,investigational product candidates, be an early entrant to the market and manufacture, market, and sell our products, independently or through collaborations. If a third party were to commercialize a competitive product, there is no assurance that we would have a basis for initiating patent infringement proceedings or that, if initiated, we would prevail in such proceedings.

Reworded

If our investigational product candidates are approved by the FDA, then potential competitors who seek to introduce generic versions of our investigational product candidates may seek to take advantage of the abbreviated approval pathway for biological products shown to be biosimilar to or interchangeable with our investigational product candidates. The Biologics Price Competition and Innovation Act of 2009 might permit these potential competitors to enter the market using a shorter and less costly development program for a biosimilar product that competes with our products. As discussed, our ability to obtain one or more types of regulatory exclusivity upon future product approval could impact the timing of approval of a competing biosimilar or interchangeable product.

Reworded

others may be able to develop products that are similar to our investigational product candidates but that are not covered by the claims of the patents that we own or license;

Reworded

During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing investigational product candidates, future products, programs or intellectual property could be diminished. Accordingly, the market price of shares of our Class A common stock may decline. Such announcements could also harm our reputation or the market for our investigational product candidates and future products,products which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

In September 2011, the Leahy-Smith America Invents Act, or Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. In particular, under the Leahy-Smith Act, the U.S. transitioned in March 2013 to a “first inventor to file” system in which, assuming that other requirements of patentability are met, the first inventor to file a patent application will be entitled to the patent regardless of whether a third party was first to invent the claimed invention. A third party that files a patent application in the USPTO after March 2013 but before us could therefore be awarded a patent covering an invention of that we also made even if we had made the invention before the invention was made independently by such third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application. Furthermore, our ability to obtain and maintain valid and enforceable patents depends on whether the differences between our technology and the prior art allow our technology to be patentable over the prior art. Since patent applications in the U.S. and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we were the first to either (1) file any patent application related to our investigational product candidates or (2) invent any of the inventions claimed in our patents or patent applications.

Reworded

Changes in U.S. patent law, or laws in other countries, could diminish the value of patents in general, thereby impairing our ability to protect our investigational product candidates.

Financial Overview

Removed

Financial Overview. Since inception, the Company has primarily been engaged in organizational activities, including raising capital, and research and development activities. The Company does not yet have a product that has been approved by the FDA, and has only generated revenues from grants, the Bahamas Registry Trials and contract manufacturing. The Company has not yet achieved profitable operations or generated positive cash flows from operations. The Company has incurred recurring losses from operations since its inception, and as of December 31, 2024 the Company had an accumulated deficit of $109.6 million. The Company expects to continue to generate operating losses for the foreseeable future.

Removed

We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2025 based on our current operating budget and cash flow forecast. However, as a result of our Type C meeting with the U.S. FDA in August 2024 with respect to the HLHS regulatory pathway, we have started to ramp up Biologics License Application (BLA) enabling activities as we currently anticipate a potential filing with the FDA in 2026 if the current ELPIS II trial is successful. Our operating expenses and capital expenditure requirements are expected to accelerate in calendar 2025 as a result of these activities, including CMC (Chemistry, Manufacturing, and Controls) and manufacturing readiness, and there will be a need to increase our current proposed spend and further increase our capital investments. We intend to seek additional financing/capital raises/non-dilutive funding options to support these activities, and current cash projections may be impacted by these ramped up activities and any financing transactions entered into. There can be no assurance we will be able to attain future financing at terms favorable to us or at all.

Operational Overview. With respect to HLHS, we are exploring the possibility that Lomecel-B™ when administered directly to the myocardium of affected infants, can improve outcomes in this devastating rare pediatric disease. The standard of care in HLHS is a series of three heart surgeries (staged surgical palliation) that reconfigures the single right ventricle to support system circulation. Despite these life-saving surgical interventions, it is estimated that only 50 to 60 percent of affected individuals survive until adolescence. The pro-vascular, pro-regenerative and anti-inflammatory properties of Lomecel-B™ may improve the function of the right ventricle in these infants. A previous Longeveron Phase 1 open-label study indicated that such a benefit may exist when outcomes were compared to historical controls. Longeveron is currently conducting a controlled study to determine the actual benefit of Lomecel-B™ in these patients.

Removed

As of February 17, 2025, we have completed five U.S. clinical studies of Lomecel-B™: Phase 1 AD, Phase 1 HLHS, Phase 1/2 Aging-related Frailty (“HERA Trial”), Phase 2a AD (CLEAR MIND Trial”), and Phase 2b Aging-related Frailty. We currently have one clinical trial actively enrolling patients: Phase 2b HLHS (“ELPIS II” trial). Additionally, we sponsor a registry in The Bahamas under the approval and authority of the National Stem Cell Ethics Committee. The Bahamas Registry Trials may administer Lomecel-B™ to eligible participants at private clinics in Nassau for a variety of indications. While Lomecel-B™ is considered an investigational product in The Bahamas, under the approval terms from the National Stem Cell Ethics Committee, we are permitted to charge a fee to participate in the Registry Trial.

Since our founding in 2014, we have focused the majority of our time and resources on the following: organizing and staffing our company, building, staffing and equipping a cGMP manufacturing facility with research and development labs, business planning, raising capital, establishing our intellectual property portfolio, generating clinical safety and efficacy data in our selected disease conditions and indications, and developing and expanding our manufacturing processes and capabilities.

Removed

We manufacture all of our own product candidates for clinical trials. In 2017 we opened a manufacturing facility comprised of eight clean rooms, two research and development laboratories, and warehouse and storage space. We have supply contracts with multiple third parties for fresh bone marrow, which we use to produce our product candidate for clinical testing and research and development. From time to time, we enter into contract development and manufacturing contracts or arrangements with third parties who seek to utilize our product development capabilities.

SinceAs theof timeDecember that31, we became a publicly traded company in February 2021,2025, we have sold 12,686,24020,328,220 shares of Class A common stock through our IPO and subsequent follow-on public and private equity offerings and transactions. Additionally, as of December 31, 2024,2025, warrants exercisable for an aggregate of up to 6,802,66821,920,318 shares of a Company'sour Class A common stock remain outstanding at exercise prices ranging from $2.35$0.85 per share to $175.00 per share.

Added

In the third quarter of 2025, we undertook two capital raising transactions. On August 11, 2025, we closed a public offering of 5,882,354 shares of Class A common stock and pre-funded warrants, which were sold together with Class A common warrants to purchase up to 14,705,885 shares of Class A Common Stock. The combined public offering price was $0.85 per share of Class A common stock and related Class A common stock warrants and $0.849 per pre-funded warrant and related Class A common stock warrants. The gross proceeds to the Company from the offering were approximately $5.0 million, before deducting the placement agent’s fees and other offering expenses payable by the Company. On September 19, 2025, we entered into an At The Market Offering Agreement (the “ATM Agreement”) providing for the sale and issuance by the Company of shares of Class A common stock from time to time, through or to H.C. Wainwright & Co., LLC (“Wainwright") as the Company’s sales agent or principal. The aggregate market value of the shares of Class A common stock eligible for sale under the ATM prospectus supplement is currently $10.7 million. See further discussion of these transactions under Capital Raising Efforts in LIQUIDITY AND CAPITAL RESOURCES section below.

Added

On March 11, 2026, we completed an initial closing of a private placement transaction with certain institutional and accredited investors, pursuant to which an aggregate of 6,013,384 shares of common stock were sold at a purchase price of $0.52 per share and 11,873.04 shares of Series A Preferred Stock convertible into an aggregate of 22,832,770 shares of common stock were sold at a purchase price of $1,000.00 per preferred share.

Added

Additionally, we agreed to sell to the investors an interest in 50% of proceeds received (after deducting necessary, documented third-party fees or charges) from the potential future sale of a Rare Pediatric Disease Priority Review Voucher to the extent received from the U.S. FDA in connection with the Company’s laromestrocel program for Hypoplastic Left Heart Syndrome (HLHS). The aggregate gross proceeds from the initial closing were approximately $15.9 million, before deducting placement agent fees and other private placement expenses. H.C. Wainwright, who acted as the exclusive placement agent for the private placement, received a cash fee equal to 7.0% and a management fee equal to 1.0%, of the aggregate gross proceeds raised.

Added

Subject to satisfaction or waiver of certain conditions discussed below, we also agreed to issue and sell to the investors additional shares of common stock and Series A Preferred Stock, respectively, in a second closing, for additional gross proceeds of approximately $15.0 million, before deducting placement agent fees and other private placement expenses. The second closing would occur upon satisfaction or waiver (by Investors holding at least a majority in interest of the Securities then held by the Investors, on an as-converted basis) of the closing conditions set forth under the Purchase Agreement, including (i) the Company’s achievement of Phase 2b study results for HLHS demonstrating statistical significance of the primary endpoint(s) as agreed between the Company and the U.S. FDA (the “Milestone”) and (ii) achievement of a volume weighted average price per share of common stock equal to or greater than $1.85 with aggregate trading volume of at least 25,000,000 shares (in each case, subject to appropriate, proportional adjustment for any stock splits or combinations of the common stock occurring after the date of the Purchase Agreement) during any ten consecutive trading days prior to expiration of the 30 trading days following the date of the Company’s first announcement via press release or a Current Report on Form 8-K of the occurrence of the Milestone.

We do not yet have a product that has been approved by the FDA, and have only generated revenues from grants, The Bahamas Registry Trial and contract manufacturing. We have not yet achieved profitable operations or generated positive cash flows from operations. We have incurred recurring losses from operations since our inception, and as of December 31, 2025 we had an accumulated deficit of $132.3 million. We expect to continue to generate operating losses for the foreseeable future. As a result of the recently completed private placement financing referenced in Note 14, Subsequent Events, and based on current operating plans, the Company expects that its cash and cash equivalents as of December 31, 2025 plus the $15.9 million in gross proceeds from the private placement will fund operations into the fourth quarter of 2026. As discussed above, the Company also has access to an ATM equity financing vehicle for sale of up to $10.7 million aggregate market value of shares of the Company’s Class A common stock. We expect that our current operating plan will require increased spending and additional capital investments to support these initiatives and we intend to seek additional financing through capital raises, non-dilutive funding options, and commercial partnering across all indications. There can be no assurance we will be able to attain future financing at terms favorable to us or at all. In the event we are unable to attain the financing needed, we will need to materially revise our current operational plans.

Added

We have prepared a cash flow forecast which indicates that we do not have sufficient cash to meet our minimum expenditure commitments for one year from the date these financial statements are available to be issued and therefore we need to raise additional funds to continue as a going concern. As a result, there is substantial doubt about our ability to continue as a going concern.

Added

We prepare our financial statements in accordance with U.S. generally accepted accounting principles, (U.S. GAAP), which requires our management to make estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. To the extent that there are material differences between these estimates and actual results, our financial condition or results of operations would be affected. We base our estimates on our own historical experience and other assumptions that we believe are reasonable after taking account of our circumstances and expectations for the future based on available information. We evaluate these estimates on an ongoing basis. We consider an accounting estimate to be critical if: (i) the accounting estimate involves a significant level of estimation uncertainty by requiring 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, had or are reasonably likely to have a material impact on our financial condition or results of operations. There are items within our financial statements that require estimation but are not deemed critical, as defined pursuant to Item 303(b)(3) of Regulation S-K. Our significant accounting policies and estimates are described in more detail in the accompanying Notes to the Financial Statements contained in this Annual Report on Form 10-K.

Removed

The discussion and analysis of our financial condition and results of operations is based upon our condensed financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, (U.S. GAAP). The preparation of these financial statements requires that we make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience, anticipated results and trends and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily available from other sources. By their nature, these estimates, judgments and assumptions are subject to an inherent degree of uncertainty, and management evaluates them on an ongoing basis for changes in facts and circumstances. Changes in estimates are recorded in the period in which they become known. Actual results may differ from our estimates under different assumptions or conditions. While our significant accounting policies and estimates are described in more detail in the accompanying Notes to the Condensed Financial Statements contained in this Annual Report on Form 10-K, we believe that the following accounting policies are those most critical due to the judgments and estimates used in the preparation of our financial statements.

Removed

Revenue recognition.

Removed

We recognize revenue associated with our contract manufacturing services, which may require us to exercise considerable judgment in estimating revenue to be recognized, including judgments made on day one accounting and judgments associated with the amount of revenue to be recognized over time as performance obligations are satisfied.

Removed

Significant judgment is required to apply the authoritative accounting guidance at the outset of our contract manufacturing services agreement, and over time, as detailed below:

Removed

Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require judgment. For our contract manufacturing services revenue, the contract generally includes the terms of the contract manufacturing services and related ancillary services or procedures to comply with regulatory requirements. We have determined, our performance obligations vary per contract and are accounted for as separate performance obligations when a product or services is delivered. If a product or service is determined not to be delivered as in the case of an initial down payment that amount is deferred and combined with another related performance obligation. If a contract contains a single performance obligation, we allocate the entire transaction price to the single performance obligation. If a contract contains multiple performance obligations, we allocate consideration to each performance obligation using the “relative standalone selling price”. Generally, we utilize observable standalone selling prices in our allocations of consideration. If observable standalone selling prices are not available, we estimate the applicable standalone selling price using a cost-plus-margin approach or an adjusted market assessment approach, in each case, representing the amount that we believe the market is willing to pay for the applicable service or product. Revenue is recognized over time using an appropriate method of measuring progress towards fulfilling our performance obligation for the respective arrangement. Determining the measure of progress that consistently depicts our satisfaction of performance obligations within each of our revenue streams across similar arrangements requires judgment.

Removed

The identified performance obligations will impact most significantly the timing of revenue recognition, and is either at a point in time or an over-time mainly based transfer of control assessment performed at the outset of the arrangement.

Removed

For revenue recognized over time, this is based on an underlying measure deemed to approximate the progress towards satisfaction of performance obligations for the respective arrangement. These underlying measures, such as costs incurred to date compared with total forecasted costs for a service, may include inherent estimates, which in turn can impact the timing of revenue recognition. For revenue recognized at a point in time, revenue is recognized once the performance obligation is satisfied, meaning the product is delivered or the service is completed, signifying the transfer of control at a specific point in time, The satisfaction of performance obligations assessment is performed at each reporting period. To date, there have been no material true ups to revenue as a result of changes in the satisfaction of performance obligations.

Removed

Going Concern Assessment

Removed

The Company has recently faced significant losses over the previous years and expects to incur losses for the foreseeable future. As a result, the company’s management has conducted an assessment of its financial condition, including cash flow projections for the next twelve months from the date the financial statements will be issued. Based on this assessment, management has identified potential material uncertainties that could cast substantial doubt on the company’s ability to continue as a going concern. This assessment includes significant assumptions and estimation of uses and forecasts of cash flows in future periods.

Removed

To address these uncertainties, management has developed a plan that includes among other things the potential for securing additional financing and non-dilutive funding such as grants. Cost reductions would also be evaluated if needed. The successful execution of these plans is contingent upon various factors some of which may be outside the Company’s control.

Removed

Given the significant judgment and subjectivity of these estimates involved in assessing the feasibility of these plans and their potential impact on future cash flows, management considers the going concern assessment to be a critical accounting estimate. The financial statements include a disclosure outlining the nature of these uncertainties, the assumptions made by management, and the potential impact on the company’s financial position and performance.

We have generated revenue from threetwo sources:

Reworded

The Bahamas Registry Trials.Trial. Participants in The Bahamas Registry Trial pay us a fee to receive Lomecel-B™,laromestrocel, imported into The Bahamas, and administered at oneLyford ofCay twoHospital, a private medical clinicsclinic in Nassau. While Lomecel-B™ is considered an investigational product in The Bahamas, under the approval terms received from the National Stem Cell Ethics Committee, we are permitted to charge a fee for participation in the Registry Trial. The fee is recognized as revenue and is used to pay for the costs associated with manufacturing and testing of Lomecel-B™,laromestrocel, administration, shipping and importation fees, data collection and management, biological sample collection and sample processing for biomarkers and other data, and overall management of the Registry, including personnel costs. Lomecel-B™Laromestrocel is considered an investigational treatment in The Bahamas and is not licensed for commercial sale. We refer to revenue generated from The Bahamas Registry Trial as clinical trial revenue in our statements of operations.

Reworded

Contract development and manufacturing services. From time to time, we enter into fee-for-service agreements with third parties for our product development and manufacturing capabilities. These agreements may include research, process development, and manufacturing services tailored to customer needs. In February 2024, we entered into our first manufacturing services contract with a third-party biotechnology company. Revenue from this contract is recognized over time as the services are provided. Additionally, the customer pays a fixed monthly fee per suite to reserve and maintain a dedicated manufacturing suite and storage space. Additional suites may also be secured based on capacity needs, which are billed at a fixed fee per suite per month. We refer to revenue generated from these services as contract manufacturing revenue in our statements of operations. During 2025, activities under the contract development and manufacturing service agreement with our customer substantially decreased. No additional manufacturing or development activities are planned and we do not anticipate significant future revenue under this agreement.

Removed

Grant awards. Extramural grant award funding, which is non-dilutive, has been a core strategy for supporting our ongoing clinical research. Since 2016 our clinical programs have received over $16.0 million in competitive extramural grant awards ($11.5 million which has been directly awarded to us and which are recognized as revenue when the performance obligations are met) from the NIH, Alzheimer’s Association, and MSCRF.

Reworded

We record cost of revenues based on expenses directly related to revenue. For grants we record allocated expenses for research and development costs to a grant as a cost of revenues. For the clinical trial revenue, directly related expenses for that program are allocated and accrued as incurred. These expenses are similar to those described under “Research and Development Expenses” below. For contract manufacturing revenue, directly related expenses for the services and facilities provided under the contract are recorded as cost of revenues.

Reworded

Research and development costs are charged to expense when incurred in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 730 Research and Development. ASC 730 addresses the proper accounting and reporting for research and development costs. It identifies: (1) those activities that should be identified as research and development; (2) the elements of costs that should be identified with research and development activities, and the accounting for these costs; and (3) the financial statement disclosures related to them.

Research and development expenses include costs such as clinical trial expenses, contracted research and manufacturing, license agreement fees with no alternative future use, supplies and materials, salaries, equity-based compensation, employee benefits, property and equipment depreciation and allocation of various corporate costs. We accrue for costs incurred by external service providers, including contract research organizations (“CROs”) and clinical investigators, based on estimates of service performed and costs incurred. These estimates include the level of services performed by the third parties, subject enrollment in clinical trials, administrative costs incurred by the third parties, and other indicators of the services completed. Based on the timing of amounts invoiced by service providers, we may also record payments made to those providers as prepaid expenses that will be recognized as expense in future periods as the related services are rendered.

Reworded

We currently do not carry any inventory for our investigational product candidates, as we have yet to launch a product for commercial distribution. Historically our operations have focused on conducting clinical trials, product research and development efforts, and improving and refining our manufacturing processes, and accordingly, manufactured clinical doses of investigational product candidates were expensed as incurred, consistent with the accounting for all other research and development costs. Once we begin commercial distribution, all newly manufactured approved products will be allocated either for use in commercial distribution, which will be carried as inventory and not expensed, or for research and development efforts, which will continue to be expensed as incurred.

Reworded

WeSubject to obtaining necessary financing, we expect that our research and development expenses will continue to be significant in the future as we increase our headcount to support increased research and development activities relating to our clinical programs, as well as incur additional expenses related to our clinical trials.

General and Administrative Expenses

Reworded

General and administrative expenses consist primarily of salaries and other related costs, including equity-based compensation, for personnel in our executive, finance, business development and administrative functions. General and administrative expenses also include public company related expenses; legal fees relating to corporate matters; insurance costs; professional fees for accounting, auditing, tax and consulting services; travel expenses; rent and facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.

Income Taxes

Removed

Interest income consists of interest earned on cash equivalents and marketable securities. The increase in interest income for the current year was primarily driven by a higher balance of cash compared to the prior year.

Reworded

No provision for income taxes has been recorded for the years ended December 31, 20242025 and 2023.2024. We may incur income taxes in the future if we have earnings. At this timetime, thewe Company hashave not evaluated the impact of any future profits.

Revenues, Cost of Revenues and Gross Profit: Revenues for the year ended December 31, 2025 were $1.2 million and consisted of $1.0 million of clinical trial revenue and $0.2 million of contract manufacturing revenue. Revenues for the year ended December 31, 2024 were $2.4 million and consisted of $1.4 million of clinical trial revenue, $0.5 million of contract manufacturing lease revenue, and $0.5 million of contract manufacturing revenue. 2025 revenues decreased $1.2 million, or 50%, when compared to 2024, as a result of lower participant demand for our Bahamas Registry Trial and reduced demand for contract manufacturing services from our third-party client.

Removed

Revenues, Cost of Revenues and Gross Profit: Revenues for the years ended December 31, 2024 and 2023 were $2.4 million and $0.7 million, respectively. 2024 revenues increased $1.7 million, or 237%, when compared to 2023 as a result of higher participant demand for our Bahamas Registry Trial and the addition of our manufacturing services contract. Clinical trial revenue, which is derived from the Bahamas Registry Trial, for the years ended December 31, 2024 and 2023 was $1.4 million and $0.7 million, respectively, reflecting an increase of $0.7 million, or 110%, when compared to 2023 as a result of increased participant demand. Contract manufacturing revenue for the year ended December 31, 2024 was $1.0 million, consisting of $0.5 million from our manufacturing lease services and $0.5 million from our manufacturing services contract.

Reworded

Related cost of revenues was $0.5$0.4 million and $0.5 million for the years ended December 31, 20242025 and 2023,2024, respectively. This resulted in a gross profit of approximately $1.9$0.8 million for the year ended December 31, 2024,2025, ana increasedecrease of $1.7$1.1 million, or 752%,57%, when compared with a gross profit of $0.2$1.9 million for 2023.2024.

Research and Development Expenses: Research and development expenses for the year ended December 31, 2025 increased to approximately $12.0 million from approximately $8.1 million for the same period in 2024. This increase of $3.9 million, or 48%, was primarily driven by a $2.2 million increase in personnel and related costs, including equity-based compensation, a $1.4 million increase in CMC costs associated with technology transfer, including non-clinical manufacturing batches that advance our readiness for future commercial production as part of our BLA-enabling efforts, and a $0.2 million increase in amortization expense related to patent costs.

Removed

Research and Development Expenses: Research and development expenses for the year ended December 31, 2024 decreased to approximately $8.1 million from approximately $9.1 million for the same period in 2023. This decrease of $1.0 million, or 10%, was primarily driven by a reduction of $2.3 million in expenses related to the completed CLEAR MIND Alzheimer’s disease clinical trial, reduced costs for the Aging-related Frailty clinical trial following our decision to discontinue trial activities in Japan, and a $0.9 million decrease in supply costs. These reductions were partially offset by $1.7 million in higher compensation and benefit costs and a $0.3 million increase in equity-based compensation expenses allocated to research and development.

Reworded

Research and development expenses consisted primarily of the following items (less those expenses allocated to the cost of revenues) (in thousands):

Added

Other Income: Other income for the year ended December 31, 2025 was $0.6 million, consisting of $0.4 million of interest earned on money market funds and $0.3 million of cash received as a recipient of a Milestone 1 Award in the XPRIZE Healthspan competition, partially offset by a $0.1 million loss on the disposal of assets. Other income for the year ended December 31, 2024 was $0.5 million, consisting primarily of interest earned on money market funds and marketable securities.

Removed

Other Income (Expense), net: Other income (expense) for the years ended December 31, 2024 and 2023 was an income of $0.6 million and an expense of $0.4 million, respectively. Net other income for 2024 was driven by a higher interest income, compared to net other expense for 2023 driven by realized losses on sales of marketable securities of $0.3 million, write-offs of intangible assets of $0.3 million and reduced benefit of tax credits of $0.3 million.

Reworded

Net Loss: Net loss decreasedincreased to approximately $16.0$22.7 million for the year ended December 31, 20242025 from a net loss of $21.4$16.0 million for the same period in 2023.2024. The decreaseincrease in the net loss of $5.4$6.7 million, or 25%,41%, was for reasons outlined above.

Added

Operating Activities. We have incurred losses since inception. Net cash used in operating activities for the year ended December 31, 2025 was $18.6 million, consisting primarily of our net loss of $22.7 million and the amortization of prepaid expenses and other current assets of $0.4 million and in operating lease asset and liability of $0.3 million. This was partially offset by non-cash expenses of $1.7 million in equity-based compensation and $1.2 million in depreciation and amortization, including intangibles. Net cash used in operating activities for the year ended December 31, 2024 was $13.9 million, consisting primarily of our net loss of $16.0 million and payments towards accounts payable of $0.5 million and a decrease in deferred revenue of $0.5 million. This was partially offset by non-cash expenses of $2.3 million in equity-based compensation expenses and $1.0 million in depreciation and amortization.

The development of pharmaceutical drugs is capital intensive. We are currently advancing laromestrocel into clinical development. As a result of the recently completed Private Placement transaction, and based on current operating plans, we expect that our cash and cash equivalents as of MarchJune 31,30, 2026 of $15.8$10.1 million, which include proceeds from the Private Placement will be adequate to fund operations into the fourth quarter of 2026. The Company also has access to an At-The-Market (ATM) equity financing vehicle for the sale of up to $10.7 million aggregate market value of shares of the Company’s Class A common stock; however, the ATM facility iswas under a standstill restriction until June 9, 2026, and thereafter we have restrictions in place regarding our ability to use the ATM facility unless our Class A common stock is trading above $0.80 per share until September 7, 2026. We will require additional funds to advance further. If we are capital constrained, we may not be able to meet our obligations. If we are unable to meet our obligations, or we experience a disruption in our cash flows, it could limit or halt our ability to continue to develop our current investigational product candidate or even to continue operations, either of which occurrence would have a material adverse effect on us.

As of MarchJune 31,30, 2026, we have sold 28,007,24228,230,871 shares of Class A Common Stock, par value $0.001 per share (the "Class A common stock") and 11,873.04 shares of Series A Non-Voting Convertible Preferred Stock, par value $0.001 per share (the "Series A preferred stock") through our IPO and subsequent follow-on public and private equity offerings and transactions. Additionally, as of MarchJune 31,30, 2026, warrants exercisable for an aggregate of up to 22,434,76021,238,731 shares of our Class A common stock remain outstanding at exercise prices ranging from $0.65 per share to $175.00 per share.

In connection with a review of itsour cash runway and cost structure and following approval from the Board of Directors (the "Board"), the Company implemented a temporary reduction in the compensation or fees payable, as applicable, of its executive officers and Board, effective on or about February 16, 2026, at rates ranging from 25% to 50%. The Company further indicated that it intended to restore compensation and fees to the amounts in effect immediately prior to such reductions at such time as the Company secured sufficient financing or other sources of capital.

Reworded

Following the initial closing of the March 2026 private placement financing discussed below (the "Private Placement,Placement"), and its good-faith determination of its financial ability to do so, the Company repaid the members of its executive leadership team an amount equal to the difference between such executive’s base salary or fee structure in effect immediately prior to the reduction and the reduced salary or fees paid during the applicable reduction period. The Company undertook the same determination with respect to Board fees and restored Board compensation to its previously established levels. Concerning the Board, because both the temporary reduction in fees and the reinstatement of such fees occurred prior to the first payment of such fees due for 2026, no repayment of any temporarily reduced fees was necessary by the Company.

Added

On March 11, 2026, the Company completed the initial closing of the Private Placement previously described in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, resulting in gross proceeds of approximately $15.9 million, before deducting placement agent fees and offering expenses. The initial closing included the issuance of Class A common stock, Series A preferred stock convertible into Class A common stock, placement agent warrants, and the sale of an interest in a portion of the potential future proceeds from the sale of a Rare Pediatric Disease Priority Review Voucher ("PRV"). The Private Placement also contemplated a second closing, subject to the satisfaction or waiver of certain closing conditions. See "Liquidity, Capital Resources, and Going Concern—Capital Raising Efforts" below for additional information regarding the Private Placement.

On March 11, 2026, we issued and sold an aggregate of 6,013,384 shares of Class A common stock at a purchase price of $0.52 per share and 11,873.04 shares of Series A preferred stock, convertible into an aggregate of 22,832,770 shares of Class A common stock, at a purchase price of $1,000.00 per Preferred Share, in the initial closing of a private placement transaction. Each share of Series A preferred stock is convertible into Class A common stock at a conversion price equal to $0.52 per share. The Company also issued to designees (or their assignees) of H.C. Wainwright & Co., LLC ("Wainwright"), our exclusive placement agent in the transaction, unregistered warrants to purchase up to 2,019,231 shares of Class A common stock which have an exercise price of $0.65 per share, which became immediately exercisable upon issuance and have a term of five years from the date of issuance. In addition, we sold an interest in 50% of proceeds received (after deducting necessary, documented third-party fees or charges) from the potential future sale of a Rare Pediatric Disease Priority Review Voucher ("PRV") to the extent received from the United States Food and Drug Administration ("FDA") in connection with the Company’s laromestrocel program for HLHS. The aggregate gross proceeds from the initial closing were approximately $15.9 million, before deducting placement agent fees and other private placement expenses. Subject to satisfaction or waiver of certain conditions discussed below, we also agreed to issue and sell to the investors additional shares of common stock and Series A Preferred Stock, respectively, in a second closing. See “Capital Raising Efforts” in the LIQUIDITY, CAPITAL RESOURCES, AND GOING CONCERN section below for further discussion of the private placement transaction.

We do not yet have a product that has been approved by the FDA, and have only generated revenues from grants, The Bahamas Registry Trial and contract manufacturing. We have not yet achieved profitable operations or generated positive cash flows from operations. We have incurred recurring losses from operations since our inception, and as of MarchJune 31,30, 2026 we had an accumulated deficit of $137.0$143.1 million. We expect to continue to generate operating losses for the foreseeable future. As a result of the recentlyMarch completed2026 Private Placement financing, and based on current operating plans, we expect that our cash and cash equivalents as of MarchJune 31,30, 2026, which include proceeds from the initial closing of the Private Placement, will be adequate to fund operations into the fourth quarter of 2026. The Company also has access to an At-The-Market (ATM) equity financing vehicle for the sale of up to $10.7 million aggregate market value of shares of the Company’s Class A common stockstock, of which $9.3 million remains available; however, the ATM facility iswas under a standstill restriction until June 9, 2026, and thereafter we have restrictions in place regarding our ability to use the ATM facility unless our Class A common stock is trading above $0.80 per share until September 7, 2026. We expect that our current operating plan will require increased spending and additional capital investments to support these initiatives and we intend to seek additional financing through capital raises, non-dilutive funding options, and commercial partnering across all indications. There can be no assurance we will be able to attain future financing at terms favorable to us or at all. In the event we are unable to attain the financing needed, we will need to materially revise our current operational plans.

Reworded

As of MarchJune 2026, we have completed five U.S. clinical studies of laromestrocel: ELPIS I Phase 1 (HLHS), Phase 1 and Phase 2a “CLEAR MIND Trial” (AD), Phase 1/2 and Phase 2b Aging-related Frailty. We currently have one fully enrolled, ongoing clinical trial: ELPIS II Phase 2b (HLHS). Additionally, we sponsor a registry in The Bahamas under the approval and authority of the National Stem Cell Ethics Committee, now known as the National Longevity and Regenerative Therapy Ethics Review Committee ("The Bahamas Registry Trial"). The Bahamas Registry Trial may administer laromestrocel to eligible participants at private clinics in Nassau, The Bahamas for a variety of indications. While laromestrocel is considered an investigational product in The Bahamas, under the approval terms from the National Stem Cell Ethics Committee, we are permitted to charge a fee to participate in The Bahamas Registry Trial.

In June 2026, we announced that the Company has been granted Small or Medium-sized Enterprise (SME) status by the European Medicines Agency (EMA). The SME program is an initiative by the EMA to address the particular needs of small and medium size companies developing medicinal products in Europe. Companies that are granted SME designation are able to seek scientific advice, protocol assistance, and other information and training from dedicated EMA personnel during the clinical development process. Companies with this designation can engage in early dialogue with the EMA multidisciplinary team and discuss regulatory strategy with the goal of mitigating delay and accelerating patient access to lifesaving treatments. In addition, SME designation gives companies reduced administrative fees throughout the development process.

Reworded

ELPIS II is a next-step trial to our completed 10-patient open-label Phase 1 trial (ELPIS I) under the same IND. The ELPIS I trial was designed to evaluate the safety and tolerability of laromestrocel as an adjunct to the second-stage HLHS surgery, and to obtain preliminary evidence of laromestrocel effect to support a next-phase trial. The primary safety endpoint was met: no major adverse cardiac events (“MACE”) or treatment-related infections during the first month post-treatment, and no triggering of stopping rules. Furthermore, fluid-based and imaging biomarker data supported multiple potentially relevant mechanisms-of-action of laromestrocel, and the potential to improve post-surgical heart function. We currently anticipate top-line results from ELPIS II in AugustSeptember 2026.

Reworded

In the Type C meeting, the FDA acknowledged that HLHS is a rare disease associated with significant morbidity and mortality with a high unmet medical need for safe and effective therapies, but also asserted that the primary endpoint of right ventricle ejection fraction (RVEF) in the ELPIS II trial is not an appropriate endpoint to demonstrate efficacy. While Longeveron agreed with the FDA regarding the insufficiency of RVEF as the primary endpoint, and was prepared to discuss other potentially appropriate endpoints sufficient to demonstrate efficacy, the FDA indicated that given the interim analysis mandated and conducted by the National Institute of Health (NIH) during the trial (to which the Company was and remains blinded), a new primary endpoint could not be agreed to while the trial is still ongoing. Without an agreed upon primary endpoint sufficient for efficacy, the FDA no longer refers to the ELPIS II trial as pivotal, as had been specifically discussed in the Company’s Type C meeting in 2024. Nevertheless, the FDA expressly agreed that it is willing to meet with Longeveron again when the ongoing ELPIS II study is completed to discuss the study results and align on a potential path forward. The FDA further indicated that only the most objective measures, including, all-cause mortality, cardiac transplant-free survival, event of cardiac transplantation, and well-defined major adverse cardiac events (MACE), could be informative of efficacy in ELPIS II, and in that regard, the Company is capturing all of these measures in ELPIS II along with some additional key measures to support an efficacy determination. TheIn June 2026, the Company intends to submitsubmitted to the FDA a Sponsor Statistical Analysis Plan (SAP) for ELPIS II with a composite primary endpoint and secondary endpoints for the FDA’s review and approval, and remains optimistic that the trial results and other available evidence will be sufficient to support filing a BLA following the readout of top-line results of the ELPIS II data.

Added

In May 2026, we announced that the independent Data Monitoring Committee (DMC) completed its final pre-specified data review for ELPIS II. The DMC performed a risk-benefit assessment, indicated no safety concerns, and approved the study to continue as designed to completion.

We believe laromestrocel is the only investigational product candidate to be granted RMAT designation for mild AD to date. In March 2025, Longeveron announced a productive Type B Meeting with the FDA supporting the advancement of laromestrocel as a potential treatment for mild AD. As a result of the Type B meeting, we reached foundationaltentative alignment with the FDA on the overall study design for a proposed single, seamless adaptive Phase 2/3 clinical trial, including proposed AD patient population, proposed placebo control, laromestrocel dose selection and frequency, trial duration, and trial endpoints that, if positive, could be acceptable for potential BLA submission for Alzheimer’s disease. We are actively seeking to forge strategic collaborations and/or partnerships for the advancement of laromestrocel in addressing mild AD.

Added

Laromestrocel data from its Phase 2b clinical trial in Aging-related Frailty were published in Cell Stem Cell in February 2026. The Phase 2b results indicated that intravenous laromestrocel improved the physical condition of patients with age-related clinical frailty after nine months, compared to placebo.

Reworded

Our IND application for laromestrocel as a potential treatment for pediatric DCM became effective in July 2025. This IND provides for moving directly to a single Phase 2 registrational clinical trial currently targeted for 2027, subject to financing, with planning and preparation beginning in 2026. If this trial is successful, we would then seek to partner the program for further development and potential commercialization.

Execution of ELPIS II to measure the efficacy of laromestrocel in HLHS. This trial is ongoing and is being conducted in collaboration with the National Heart, Lung, and Blood Institute (“NHLBI”) through grants from the NIH. As announced on June 24, 2025, the trial has reached full enrollment and we anticipate top-line trial results for ELPIS II in AugustSeptember 2026. If the current ELPIS II trial in HLHS is successful, and the trial results and other available evidence are deemed sufficient by the FDA to support filing a BLA following the readout of top-line results of the ELPIS II data, then we would intend to pursue a potential BLA filing with the FDA and a commercialization partner.

COMPARISON OF THE THREE MONTHS ENDED MARCHJUNE 31,30, 2026 AND 2025

Reworded

The following table summarizes our results of operations for the three months ended MarchJune 31,30, 2026 and 2025, together with the changes in those items in dollars (in thousands):

Added

Revenues, Cost of Revenues and Gross Profit: Revenues for each of the three-month periods ended June 30, 2026 and June 30, 2025 was $0.3 million. 2026 revenues decreased by $29,000, or 10%, when compared to 2025, primarily due to the absence of contract manufacturing revenue.

Added

Clinical trial revenue, which is derived from The Bahamas Registry Trial, for each of the three-month periods ended June 30, 2026 and June 30, 2025 was $0.3 million. Contract manufacturing revenues for the three months ended June 30, 2026 and 2025, were $0 and $18,000, respectively. This decrease of $18,000, or 100%, when compared to the same period in 2025, was driven by the absence of any additional contract manufacturing services from our third-party client.

Removed

Revenues, Cost of Revenues and Gross Profit: Revenues for the three months ended March 31, 2026 were $0.4 million and consisted of $0.4 million of clinical trial revenues and $20,000 of contract manufacturing revenues.

The Company also received approximately $0.9 million in cash from a sale to the investors in the Private Placement of an interest in 50% of the future proceeds from the potential future sale of a Rare Pediatric Disease Priority Review Voucher to the extent received from the U.S. FDA in connection with the Company's laromestrocel program for HLHS. Net cash used in financing activities for the threesix months ended MarchJune 31,30, 2025 was less than $0.1$0.2 million for the payment of taxes upon vesting of RSUs.

Reworded

To date, we have financed our operations primarily through our IPO, registered and private placement equity financings, grant awards, fees generated from The Bahamas Registry Trial and contract manufacturing services. Since we were formed, we have raised approximately $136.0 million in gross proceeds from the issuance of equity, including $15.9 million in gross proceeds from the Private Placement in March 2026. At MarchJune 31,30, 2026, we had cash and cash equivalents of $15.8$10.1 million and working capital of $12.5$7.0 million.

Reworded

We intend to seek additional financing opportunities, capital raises, as well as non-dilutive funding options to support our operating plans. Additionally, following a positive Type B meeting with the FDA in March 2025 with respect to the Alzheimer's disease (AD) regulatory pathway, we are focused on seeking partnership opportunities and/or non-dilutive funding for the AD program, including a proposed single, seamless adaptive Phase 2/3 clinical trial. There can be no assurance we will be able to attain future financing at terms favorable to us or at all. In the event we are unable to attain the financing needed, we will need to materially revise our current operational plan. We do not have sufficient cash to meet our minimum expenditure commitments for one year from the date these unaudited condensed financial statements are available to be issued, and therefore we need to raise additional funds to continue as a going concern. As a result, there is substantial doubt about our ability to continue as a going concern.

Reworded

As of MarchJune 31,30, 2026, we have sold 28,007,24228,230,871 shares of Class A common stock and 11,873.04 shares of Series A preferred stock through our IPO and subsequent follow-on public and private equity offerings and transactions. Additionally, as of MarchJune 31,30, 2026, warrants exercisable for an aggregate of up to 22,434,76021,238,731 shares of our Class A common stock remain outstanding at exercise prices ranging from $0.65 per share to $175.00 per share.

Pursuant to an agreement with Wainwright dated September 19, 2025 (as amended, the “ATM Agreement”), the Company also has access to an At-The-Market (ATM) equity financing vehicle, providing for the sale and issuance by the Company of shares of Class A common stock from time to time, through or to Wainwright as the Company’s sales agent or principal. The gross sales price of the shares of Class A common stock sold by Wainwright under the ATM Agreement as sales agent shall be the market price for the shares of Class A common stock on Nasdaq at the time of sale. The aggregate market value of the shares of Class A common stock eligible for sale under the ATM prospectus supplement is currently $10.7 million. However, the ATM facility is under a standstill restriction until June 9, 2026, and thereafter we have restrictions in place regarding our ability to use the ATM facility unless our Class A common stock is trading above $0.80 per share until September 7, 2026.

Reworded

On March 10, 2026, the Company entered into a Securities Purchase Agreement with certain institutional and accredited investors providing for a private placement of Class A common stock, Series A preferred stock and certain related rights in up to two closings (the "Private Placement"). The initial closing occurred on March 11, 2026 and resulted in gross proceeds of approximately $15.9 million, before deducting placement agent fees and other offering expenses. Additional information regarding the Private Placement, including the securities issued, the related interest in potential proceeds from the sale of a Rare Pediatric Disease Priority Review Voucher ("PRV"), the placement agent warrants and compensation arrangements, and the terms of the Series A preferred stock, is included in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2026.

Pursuant to the Purchase Agreement, subject to the satisfaction or waiver of specified closing conditions, the Company may complete a second closing for additional gross proceeds of approximately $15.0 million, before deducting placement agent fees and other offering expenses. The second closing is contingent upon the achievement (or waiver) of certain clinical and market-based milestones, as set forth in the Purchase Agreement, including specified Phase 2b HLHS study results and a minimum trading price and volume threshold.

On March 10, 2026, we entered into a Purchase Agreement with certain institutional and accredited investors (each, an “Investor” and collectively, the “Investors”), pursuant to which we agreed to issue and sell shares of the Company’s Class A common stock and Series A preferred stock (the “Series A preferred stock,” and together with the Class A common stock, the “Private Placement Securities”) to the Investors in up to two closings in a private placement (the “Private Placement”). At initial closing on March 11, 2026 we issued and sold an aggregate of 6,013,384 shares of Class A common stock at a purchase price of $0.52 per share and 11,873.04 shares of Series A preferred stock, convertible into an aggregate of 22,832,770 shares of Class A common stock, at a purchase price of $1,000.00 per share of Series A preferred stock. Each share of Series A preferred stock is convertible into Class A common stock at a conversion price equal to $0.52 per share. The powers, preferences, rights, qualifications, limitations and restrictions applicable to the Series A preferred stock are set forth in the Company’s Certificate of Designation filed on March 10, 2026.

Removed

Additionally, the Company agreed to sell to the Investors an interest in 50% of proceeds received (after deducting necessary, documented third-party fees or charges) from the potential future sale of a Rare Pediatric Disease Priority Review Voucher to the extent received from the U.S. FDA in connection with the Company’s laromestrocel program for HLHS.

Removed

Pursuant to the Purchase Agreement, subject to the occurrence of a Second Closing Trigger Date (as defined below), we agreed to issue and sell to the Investors additional shares of Class A common stock and Series A preferred stock, respectively, for additional gross proceeds of approximately $15.0 million, before deducting placement agent fees and other expenses. The Second Closing Trigger Date shall occur upon satisfaction or waiver of the closing conditions set forth under the Purchase Agreement, including (i) the Company’s achievement, during the period from March 11, 2026 and ending on the announcement of Phase 2b study results for HLHS demonstrating statistical significance of the primary endpoint(s) as agreed between the Company and the U.S. FDA (the “Milestone”) and (ii) achievement of a volume weighted average price per share of Class A common stock equal to or greater than $1.85 with aggregate trading volume of at least 25,000,000 shares (in each case, subject to appropriate, proportional adjustment for any stock splits or combinations occurring after the date of the Purchase Agreement) (the “Price Threshold”) measured during any ten consecutive trading days prior to expiration of the 30 trading days following the date of our first announcement via press release or a Current Report on Form 8-K of the occurrence of the Milestone. Investors holding at least a majority in interest of the Private Placement Securities may choose to waive achievement of the Milestone and Price Threshold and proceed with the second closing.

Removed

The aggregate gross proceeds from the Initial Closing were approximately $15.9 million, before deducting placement agent fees and other expenses. Wainwright acted as the exclusive placement agent for the Private Placement, for which it received a cash fee equal to 7.0% of the aggregate gross proceeds raised in the Private Placement, plus a management fee equal to 1.0% of the aggregate gross proceeds raised in the Private Placement and reimbursement for certain expenses. We also issued to designees of Wainwright (or their assignees) unregistered warrants to purchase up to 2,019,231 shares of Class A common stock which have an exercise price of $0.65 per share, which became immediately exercisable upon issuance and have a term of five years from the date of issuance.

Reworded

Since 2016 through MarchJune 31,30, 2026, we have been directly awarded approximately $11.5 million in governmental and non-profit association grants, which have been used to fund our clinical trials, research and development, production and overhead. Grant awards are recognized as revenue, and depending on the funding mechanism, are deposited directly in our accounts as lump sums, which are staggered over a predetermined period or drawn down from a federal payment management system account for reimbursement of expenses incurred. Revenue recognition occurs when the grant relatedgrant-related expenses are incurred or supplies and materials are received. We have had no grant revenue since 2023. As of MarchJune 31,30, 2026 and December 31, 2025, we had no unused grant funds available for us to draw.

Reworded

As of MarchJune 31,30, 2026, we have $0.8$0.6 million in operating lease obligations and no CRO payment obligations. From time to timetime-to-time we may enter into contracts in the normal course of business with third-party contract organizations for clinical trials, preclinical studies, manufacturing and other services and products for operating purposes. These contracts generally provide for termination following a certain period after notice and therefore we believe that our non-cancelable obligations under these agreements are not material.
