Previous wording

Given the novelty of our technologies, we intend to work closely with the FDA and comparable foreign regulatory authorities to perform the requisite scientific analyses and evaluation of our methods to obtain regulatory approval for our product candidates. However, due to a lack of experience with similar therapeutics or delivery methods, the regulatory pathway with the FDA and comparable foreign regulatory authorities may be more complex, time-consuming, and unpredictable relative to more well-known therapeutics. For example, even if we obtain human data to support continued evaluation and approval of our product candidates, the FDA or comparable foreign regulatory authorities may lack experience in evaluating the safety and efficacy of therapeutics similar to our product candidates or may scrutinize such data more closely than data generated from more established types of biological products. In addition, given that there are no approved PSC-derived cell therapy products on the market, the FDA and comparable foreign regulatory authorities have not established consistent standards by which to evaluate the safety of such products, and any such standards that they do establish may subsequently change. Moreover, the FDA remains focused on potential safety issues associated with gene and cell therapy products, and as the number of new gene and cell therapy product candidates submitted for FDA review has increased in recent years, the number of clinical holds imposed by the FDA has also increased. For example, the FDA has placed clinical holds on certain product candidates pending further evaluation of genomic abnormalities detected in as few as a single patient following administration of such product candidates. We cannot be certain that the FDA or comparable foreign regulatory authorities will determine that the potential safety risks associated with our product candidates outweigh the potential therapeutic benefits in each indication for which we develop our products, and that they will allow us to commence clinical trials of such product candidates in a timely manner, or at all, or to continue such clinical trials in accordance with our timelines or at all after they have commenced. If we become subject to a clinical hold with respect to any of our product candidates due to a potential safety issue, we cannot guarantee that we will be able to provide the applicable regulatory authority with sufficient data or other evidence regarding the safety profile of such product candidate such that we will be able to commence or resume clinical development of such product candidates in a timely manner or at all. Any such event could delay clinical development of such product candidate, including in other indications, or our other product candidates, increase our expected development costs, increase the length of the regulatory review process, and delay or prevent commercialization of our product candidates. In addition, the evaluation process for our produ…

Additionally, the use of stem cells generally, and ESCs, in particular, has social, legal, and ethical implications. Certain political and religious groups continue to voice opposition to the use of human stem cells in drug research, development, and manufacturing. Adverse publicity due to ethical and social controversies surrounding the use of stem cells could lead to negative public opinion, difficulties enrolling patients in our clinical trials, increased regulation, and stricter policies regarding the use of such cells, which could harm our business and may limit market acceptance of any of our product candidates that may receive regulatory approval. In addition, clinical experience with stem cells, including iPSCs and ESCs, is limited. We are not aware of any products utilizing iPSCs or ESCs as a starting material that have received marketing approval from the FDA or a comparable foreign regulatory authority. Therefore, patients in our clinical trials may experience unexpected side effects, and we may experience unexpected regulatory delays prior to or, if approval were to be granted, after regulatory approval.

The security of our network, systems, and information, including data, may also be subject to threats involving misuse by our current or former employees or third parties involved in our operations, including service providers, contractors, vendors, or partners, whether intentional or unintentional. For example, we are subject to the risk that employees may inadvertently share confidential information with unintended third parties, or that departing employees may take, or create their own information based on, our confidential information upon leaving the company. In addition, any such insiders may be the victims of social engineering attacks that enable unauthorized third parties to access our network, systems, and information using an authorized person’s credentials, and such attacks may be more likely to succeed when conducted using AI Technologies. We and our network, systems, and information are also vulnerable to malicious acts by insiders, including leaking, modifying, or deleting confidential information, or performing other acts that could materially interfere with our operations and business. Although we provide regular training to our employees regarding cybersecurity threats and best practices, we cannot ensure that such training or other efforts will prevent unauthorized access to or sabotage of our network, systems, and information.

We currently and in the future will need to maintain and protect our trademarks and trade names to ensure, among other things, name recognition by potential partners and, if our products receive regulatory approval, customers in our markets of interest. We may not be able to protect our rights in our current or future trademarks and trade names or may be forced to stop using these trademarks or trade names, including as a result of such trademarks and trade names being challenged, infringed, circumvented, or declared generic or descriptive, or being determined to infringe on other marks. In any such case, we may no longer be able to enforce or use our rights in these trademarks and trade names. During trademark registration proceedings, our applications may be rejected by the USPTO or comparable foreign agencies. Although we would be given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in the USPTO and in many comparable foreign agencies, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively, and our business may be adversely affected. We may license our trademarks and trade names to collaborators or to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these guidelines or misuse of our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names.

Furthermore, the patent position of companies in the biopharmaceutical industry is particularly uncertain. Various courts, including the United States Supreme Court, have rendered decisions that could negatively affect the actual or perceived value of patents, such as recent federal district and appellate court rulings that have narrowed the scope of patent protection available in certain circumstances, weakened the rights of patent owners in certain situations, and in certain cases invalidated patents entirely. For example, in its 2023 decision in Amgen v. Sanofi, the United States Supreme Court held that a functionally-claimed genus was invalid for failing to comply with the enablement requirement of the Patent Act. In addition, the Federal Circuit’s 2023 decision in In re: Cellect, LLC, which considered the interaction of PTAs, terminal disclaimers, and obvious-type double patenting, may negatively affect the patent term of any issued patents that rely on any PTA. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents once obtained. Depending on decisions by Congress, the federal courts, the USPTO, and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. For example, in the 2013 case Assoc. for Molecular Pathology v. Myriad Genetics, Inc., the United States Supreme Court held that certain claims to naturally occurring substances are not patentable. Although we do not believe that any of the patents owned or licensed by us will be found invalid based on this decision, we cannot predict how future decisions by Congress, the federal courts, the USPTO, or the relevant law-making bodies in other countries may impact the value of our patents. For example, the Inflation Reduction Act (IRA) authorizes the Secretary of the Department of Health and Human Services (HHS) to negotiate prices directly with participating manufacturers for selected medicines covered by Medicare even if these medicines are protected by an existing patent. While we do not believe that the IRA or its effects will impact our ability to obtain patents in the near future, we cannot be certain whether and to what extent it will affect our longer-term patent strategy or our business. Additionally, in July 2025, the FDA announced its intent to increase transparency by publicly releasing complete response letters (CRLs) issued to drug and biologic sponsors, and subsequently announced it would release in “real time” newly issued CRLs. CRLs, which are issued when a BLA or New Drug Application cannot be accepted in its current form, outline the reasons for non-approval and may contain confidential or proprietary information relating to the applicant’s p…

The ability of the FDA to review and approve new products may be affected by a variety of factors, including government budget and funding levels, changes in federal agency leadership, statutory, regulatory, and other governmental changes, including government administration policy actions, such as those relating to hiring and return-to-office, and policies implemented by the Department of Government Efficiency, including reduction-in-force initiatives, the FDA’s ability to hire and retain key personnel, including personnel with the expertise necessary to evaluate product candidates such as ours, and accept the payment of user fees, and other events that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the FDA have fluctuated in recent years. Moreover, these and other factors have increased the uncertainties associated with interpreting the FDA’s guidance and predicting its areas of focus and responses to various issues. In addition, government funding of the FDA and other government agencies, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable and could lead to changes in agency funding that make it more difficult or costly to operate our business. For example, the United States government has, and may in the future, take actions that could impact the extent to which NIH grantees can receive funds for indirect costs associated with research activities, and we cannot predict how and the extent to which any such actions may impact our business. Disruptions at the FDA and other agencies, such as staffing changes that have occurred and may occur in the future, may also extend the time necessary for new biologics or modifications to licensed biologics to be reviewed or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the United States government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities. If a prolonged government shutdown, a lapse in government appropriations or funding, or other disruption occurs, or if global health concerns, staffing shortages, budget restrictions, or other factors such as those described above prevent the FDA or comparable foreign regulatory authorities from conducting their normal operations, such as regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or comparable foreign regulatory authorities to timely review and process our regulatory submissions. Such factors could also harm the ability of other government agencies with which we interact in the normal course of business to carry out their core functions. The occurrence of any of the foregoing could have a material adverse effect on our business.

Most significantly, on August 16, 2022, President Biden signed the IRA into law. This statute marks the most significant action by Congress with respect to the pharmaceutical industry since adoption of the ACA in 2010. Among other things, the IRA requires, beginning in 2026, manufacturers of certain drugs to engage in price negotiations with Medicare, with prices that can be negotiated subject to a cap; imposes rebates, first due in 2023, under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation; and, effective in 2025, replaces the Part D coverage gap discount program with a new discounting program. The IRA permits the Secretary of HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. HHS has issued and will continue to issue and update guidance as these programs are implemented. Only high-expenditure single-source drugs that have been approved for at least seven years (11 years for single-source biologics) can qualify for negotiation, with the negotiated price taking effect two years after the selection year. For 2026, the first year in which negotiated prices become effective, CMS selected ten high-cost Medicare Part D drugs in 2023, negotiations began in 2024, and the negotiated maximum fair price for each drug has been announced. CMS has selected 15 additional Medicare Part D drugs for negotiated maximum fair pricing in 2027. For 2028, up to an additional 15 drugs, which may be covered under either Medicare Part B or Part D, will be selected, and for 2029 and subsequent years, up to 20 additional Part B or Part D drugs will be selected. Various industry stakeholders, including certain pharmaceutical companies and the Pharmaceutical Research and Manufacturers of America, have initiated lawsuits against the federal government asserting that the price negotiation provisions of the IRA are unconstitutional. The impact of the IRA and ongoing and future legislative, executive, judicial, and administrative actions and any healthcare measures and agency rules on the pharmaceutical industry generally, and on our business specifically, is uncertain. If we obtain regulatory approval for any of our product candidates, the IRA could substantially and negatively impact the prices we may charge for such products, which could harm our ability to generate revenue and achieve and sustain profitability.

In June 2026, CMS issued a proposed rule that would codify policies established in guidance documents for the Medicare Drug Price Negotiation Program for initial price applicability year 2029 and beyond. CMS plans to release guidance to implement policies related to the effectuation of the maximum fair pricing for the Medicare Drug Price Negotiation Program for 2028. Various industry stakeholders, including certain pharmaceutical companies and the Pharmaceutical Research and Manufacturers of America, have initiated lawsuits against the federal government asserting that the price negotiation provisions of the IRA are unconstitutional.

Further, there have been a number of, and there may in the future be, other policy, legislative, and regulatory proposals aimed at changing the pharmaceutical industry. The United States government, state legislatures, and foreign governmental entities have shown significant interest in implementing cost containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement and coverage, drug importation programs and proposals, and requirements for substitution of generic products for branded prescription drugs. For example, the current government administration has introduced various measures to address prescription drug pricing and access, including through issuance of an executive order aiming to establish a “most-favored-nation” drug pricing policy that would tie United States drug prices to the prices paid for drugs in other countries, which has prompted and may lead to additional government and industry action in furtherance this policy, including agreements between the government and major pharmaceutical companies designed to bring American drug prices in line with the lowest price paid by other developed nations and the potential rollout of direct-to-consumer drug purchasing programs and platforms. In particular, the current administration has directed the Secretary of HHS to establish a mechanism through which American patients can buy drugs directly from manufacturers who sell at a most-favored-nation price and directed the United States Trade Representative and Secretary of Commerce to take action to ensure foreign countries are not engaged in practices that purposefully and unfairly undercut market prices and drive price hikes in the U.S. In addition, in November 2025, CMS announced a voluntary initiative called the GENEROUS Model (GENErating cost Reductions fOr U.S. Medicaid Model) to introduce the option of most-favored-nation pricing to the Medicaid program, whereby a drug manufacturer may voluntarily offer supplemental rebates to participating state Medicaid programs for a manufacturer’s covered outpatient drugs. Government agreements with pharmaceutical companies and other measures that use most-favored-nation pricing targets for prescription drugs or that increase generic and biosimilar drug entry sooner than expected could have a material adverse effect on our industry and our business generally, including by harming our ability to set adequate pricing for new drugs to recover research and development costs, our ability to attract potential investors and potential buyers in the future, or the pricing of any of our approved products in the United States or in foreign countries, and discouraging the commercialization of products outside of the United States. The timing and extent of implementation of any of the measures described above is uncertain and we cannot fully predict their impact on our product candidates and our business.

In addition, we or our partners or vendors may maintain or otherwise have access to sensitive identifiable personal information, including health information, that we receive throughout the clinical trial process, in the course of our research collaborations, and directly from individuals (or their healthcare providers) who may enroll in our patient assistance programs, if any. We may become subject to further obligations under HIPAA as a result of our access to such information. In addition, the HIPAA Standards for Privacy of Individually Identifiable Health Information (Privacy Rule) and the Security Standards for the Protection of Electronic Protected Health Information under HIPAA and HITECH are the subjects of final and proposed rule amendments, respectively. Additionally, many provisions of the final amendments to the Privacy Rule were vacated by a federal court in June 2025, and may be the subject of further proposed amendments. We may be required to modify our policies and practices to address these and other updates to the rules implementing HIPAA and HITECH.

In particular, there is currently significant uncertainty about the future relationship between the United States and various other countries, in particular China, with respect to trade policies, including sanctions, treaties, tariffs, taxes, regulatory requirements, and other limitations on cross-border operations, including due to government administration policy changes that have occurred or may occur in the future. The United States government has and continues to make significant additional changes in United States trade policy and may continue to take future actions that could negatively impact United States trade. For example, the United States government has indicated its intent to modify United States trade policy and, in some cases, to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. In addition, since February 2025, the United States has implemented, and in certain cases, increased, tariffs on a wide array of foreign products from almost all trading partners. For example, in April 2025, the United States Department of Commerce (Department of Commerce) initiated an investigation related to imports of pharmaceuticals and pharmaceutical ingredients, and their derivative products, under Section 232 of the Trade Expansion Act of 1962 (Section 232), the results of which led to the announcement in April 2026 of a new tariff of up to 100% on certain patented and branded pharmaceuticals and associated pharmaceutical ingredients, effective in the second half of 2026. The administration continues to implement new, reinstated, or adjusted tariffs on a broad array of items, and we expect that this practice may continue. For example, the Department of Commerce has initiated additional Section 232 investigations into national security risks associated with the import of certain additional commodities, and the Office of the United States Trade Representative has initiated investigations under Section 301 of the Trade Act of 1974 into the trade policies and actions of certain United States trading partners, including China and the EU. The findings of these investigations, or future investigations under these or other authorities, could eventually support the imposition of additional tariffs. Between February 2025 and February 2026, the administration imposed “reciprocal” and “fentanyl-related” tariffs on imports of certain items and from various trading partners, citing authorities provided for in the International Emergency Economic Powers Act (IEEPA). Following a Supreme Court ruling in February 2026 determining that these tariff actions were unauthorized, the government rescinded the IEEPA tariffs, but subsequently implemented a global “temporary import surcharge” on many of the same imports under authorities provided for in Section 122 of the Trade Act of 1974. The extent and duration of any tariffs, the uncertainty around their implementation and the timing thereof, and the resulting impact on ge…

As of March 31, 2026, we had $101.1 million in cash, cash equivalents, and marketable securities. As described elsewhere in this Quarterly Report, due to our recurring operating losses and negative cash flows from operations, management has determined that our present capital resources may not be sufficient to fund our planned operations for at least one year from the date of this Quarterly Report, raising substantial doubt as to our ability to continue as a going concern. Accordingly, we will need to raise additional funding in order to execute on our current business plans and strategy. As described elsewhere in these Risk Factors, we cannot guarantee that financing will be available in sufficient amounts or on terms acceptable to us, if at all, and the terms of any financing may adversely affect our stockholders. Moreover, we could use our capital resources more quickly than we currently expect, which could require us to seek additional funds sooner than planned, including through public or private equity or debt financings or other sources, such as strategic collaborations. Attempting to secure additional financing may divert our management from our day-to-day activities, which may adversely affect our ability to develop our product candidates, and the issuance of additional securities, whether equity, traditional debt, or other debt-like arrangements, by us, or the possibility of such issuance, may cause the market price of our shares to decline. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.

We have a limited operating history. Biotechnology product development is a highly speculative undertaking and involves a substantial degree of risk. We have incurred significant losses since inception, have not generated any revenue from product sales, and have financed our operations historically through several equity financings. We expect that it will be several years, if ever, before we have a commercialized product and generate revenue from product sales. We had net losses of $47.2 million and $49.4 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, we had an accumulated deficit of $1.9 billion, which includes cumulative non-cash charges related to the revaluation of our success payment liabilities and contingent consideration of $14.5 million and $83.2 million, respectively. Our losses have resulted principally from expenses incurred for the research and development of ourex vivo andin vivo cell engineering platforms, management and administrative costs, and other expenses incurred while building our business infrastructure.

We agreed to make success payments, payable in cash, pursuant to our license agreement with Harvard and contingent consideration and success payments, payable in cash or stock, pursuant to our acquisition agreement with Cobalt. Pursuant to the terms of our license agreement with Harvard, we may be required to make up to an aggregate of $175.0 million in success payments to Harvard (Harvard Success Payments), payable in cash, based on increases in the per share fair market value of our common stock. The potential Harvard Success Payments are based on multiples of increasing value ranging from 5x to 40x based on a comparison of the per share fair market value of our common stock relative to the original issuance price of $4.00 per share at ongoing pre-determined valuation measurement dates. The Harvard Success Payments can be achieved over a maximum of 12 years from the effective date of the agreement. If a higher success payment tier is met at the same time a lower tier is met, both tiers will be owed. Any previous Harvard Success Payments made are credited against the Harvard Success Payment owed as of any valuation measurement date so that Harvard does not receive multiple success payments in connection with the same threshold. As of March 31, 2026, a Harvard Success Payment had not been triggered. See Note 5, License and collaboration agreements to our condensed consolidated financial statements included elsewhere in this Quarterly Report for more details on the various per share common stock values that trigger a Harvard Success Payment.

Pursuant to the terms of the Cobalt acquisition agreement, we are obligated to pay to certain former Cobalt stockholders contingent consideration (Cobalt Contingent Consideration) of up to an aggregate of $500.0 million upon our achievement of certain pre-defined development milestones and a success payment (Cobalt Success Payment) of $500.0 million, each of which is payable in cash or stock. The Cobalt Success Payment is payable if, at pre-determined valuation measurement dates, our market capitalization equals or exceeds $8.1 billion, and we are advancing a program based on the fusogen technology in a clinical trial pursuant to an IND, or have filed for, or received approval for, a BLA or new drug application for a product based on the fusogen technology. The Cobalt Success Payment can be achieved over a maximum of 20 years from the date of the acquisition, but this period could be shorter upon the occurrence of certain events. A valuation measurement date would be triggered upon a change of control if at least one of our programs based on the fusogen technology is the subject of an active research program at the time of such change of control. If there is a change of control and our market capitalization is below $8.1 billion as of the date of the change of control, the amount of the potential Cobalt Success Payment will decrease, and the amount of potential Cobalt Contingent Consideration will increase. As of March 31, 2026, a Cobalt Success Payment had not been triggered. See Note 4, Acquisitions to our condensed consolidated financial statements included elsewhere in this Quarterly Report for details on the amount of the potential Cobalt Success Payment and potential Cobalt Contingent Consideration if there is a change of control based on various thresholds for our market capitalization on such change of control date.

The Cobalt Success Payment would alternatively be payable upon a change of control if at least one of our products based on the fusogen technology is the subject of an active research program at the time of such change of control. If our market capitalization is below $8.1 billion as of the date of such change of control, the amount of the potential Cobalt Success Payment will decrease, and the amount of potential Cobalt Contingent Consideration will increase.

Our success payment and contingent consideration obligations under our license and acquisition agreements are recorded as liabilities on our balance sheets. Under United States generally accepted accounting principles (GAAP), we are required to estimate the fair value of these liabilities as of each quarter end, with changes in the estimated fair value recorded in research and development-related success payments and contingent consideration. Factors that may lead to increases or decreases in the estimated fair value of the success payment liabilities include, among others, changes in the value of our common stock and market capitalization, changes in volatility, the estimated number and timing of valuation measurement dates, the term of the success payments, and changes in the risk-free interest rate. Factors that may lead to increases or decreases in the estimated fair value of our contingent consideration obligations include, among others, the estimated likelihood and timing within which milestones may be achieved and the estimated discount rates. A small change in the inputs and related assumptions with respect to our success payment liabilities and contingent consideration may result in a relatively large change in the estimated valuation and associated liabilities and resulting expense or gain. As a result, our operating results, net losses, and financial condition as reported by GAAP may fluctuate significantly from quarter to quarter and year to year for reasons unrelated to our operations, which may reduce the usefulness of our GAAP financial statements. For example, as of March 31, 2026 and December 31, 2025, the estimated aggregate fair value of the Cobalt Success Payment and Harvard Success Payment liabilities was $16.9 million and $19.2 million, respectively, and the estimated fair value of the Cobalt Contingent Consideration was $134.5 million and $123.7 million, respectively.

For the three months ended March 31, 2026, we recorded gains of $1.8 million and $0.5 million, respectively, related to the aggregate change in the estimated fair value of the Cobalt Success Payment and Harvard Success Payment liabilities. For the three months ended March 31, 2026, we recorded an expense of $10.7 million related to the change in the estimated fair value of the Cobalt Contingent Consideration. We have incurred net losses since our inception and expect to continue to incur net losses for the foreseeable future. It is possible that future fluctuations in the price of our common stock and market capitalization and the resulting change in the estimated fair value of our success payment liabilities could lead us to record net income in a future period despite us incurring operating losses and negative cash flows during such period. Alternatively, significant stock appreciation during a future period could lead to a significant increase in our recorded GAAP net loss.

As of March 31, 2026, our executive officers, directors, holders of 5% or more of our capital stock, and their respective affiliates, beneficially owned, in the aggregate, approximately 52.7% of our common stock. Therefore, these stockholders have the ability to influence us through this ownership position. These stockholders may be able to determine all matters requiring stockholder approval. For example, these stockholders may be able to control elections of directors, amendments to our organizational documents, or approval of any merger, sale of assets, or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock that other stockholders may feel are in their best interests.

We expect that we will need significant additional capital in the future to support our planned operations, including conducting clinical trials, manufacturing, and other research and development activities, commercializing any product candidates for which we may obtain regulatory approval, and continuing to operate as a public company. To raise capital, we have sold and may in the future sell shares of our common stock, warrants, convertible securities, or other securities in one or more transactions at prices and in a manner we determine from time to time, including shares of common stock in the ATM facility and shares of common stock and pre-funded warrants in our August 2025 and February 2024 underwritten public offerings, as described elsewhere in this Quarterly Report. In the future, we may issue additional securities, including shares of common stock or other equity or debt securities convertible into common stock, in connection with the ATM facility, a financing, acquisition, employee arrangement, or otherwise. Any such issuance could result in substantial dilution to our existing stockholders, cause the price of our common stock to decline, and result in new investors gaining rights, preferences, and privileges senior to the holders of our common stock.
