Any of the previously identified or similar threats may cause a security incident or other interruption that may result in unauthorized, unlawful or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of or access to our sensitive information or our information technology systems, or those of the third parties with whom we work. We may need to expend significant resources or modify our business activities (including our clinical trial activities) to try to protect against any security incidents.
Current report
We operate in a global economy, which includes utilizing third-party suppliers in certain countries outside the United States. There is inherent risk, based on the complex relationships among the U.S. and the countries in which we conduct our business, that political, diplomatic and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. The current international trade and regulatory environment is subject to significant ongoing uncertainty. The U.S. government has announced substantial new tariffs affecting a wide range of products and jurisdictions and has indicated an intention to continue developing new trade policies, including with respect to the biopharmaceutical industry. In response, certain foreign governments have announced or implemented retaliatory tariffs and other protectionist measures. Since then, the U.S. government has announced various trade deals and ongoing negotiations with other countries and regions. In addition, the Bureau of Industry and Security, U.S. Department of Commerce, had initiated an investigation and determined that pharmaceutical ingredients, including finished drug product, manufactured outside the United States posed a national security risk and should be subject to additional tariffs. As relevant policies are rapidly evolving, it may be difficult to evaluate their potential future impacts. These developments have created a dynamic and unpredictable trade landscape, which may adversely impact our business, results of operations, financial condition and prospects.

Other international and geopolitical events could also have a serious adverse impact on our business. While we cannot predict the broader consequences, these conflicts and retaliatory and counter-retaliatory actions could materially adversely affect global trade, currency exchange rates, inflation, regional economies and the global economy, which in turn may increase our costs, disrupt our supply chain, impair our ability to raise or access additional capital when needed on acceptable terms, if at all, or otherwise adversely affect our business, financial condition and results of operations.

Previous report
We believe our culture has been a key contributor to our successes to date. Any failure to preserve our culture could negatively affect our ability to retain and recruit personnel, which is critical to our growth, and to effectively focus on and pursue our objectives. Prior reductions in workforce may adversely impact our culture. Alternatively, as the organization again starts to grow, such as would be expected to support commercialization, and we are required to implement more complex organizational management structures, we may find it increasingly difficult to maintain the beneficial aspects of our culture. If we fail to maintain our company culture, our business may be adversely affected.

Furthermore, our third-party manufacturers would also be subject to the same risks we face in developing our own manufacturing capabilities, as described above. Each of these risks could delay our clinical trials, the approval, if any, of our product candidates by the FDA or comparable foreign regulatory authorities or the commercialization of our product candidates or result in higher costs or deprive us of potential product revenue.
Previous report
In addition, there continues to be heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several U.S. presidential executive orders, Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under government payor programs and review the relationship between pricing and manufacturer patient programs. For example, the IRA, among other things: (i) directs the U.S. Department of Health and Human Services (HHS) to negotiate the price of certain high-expenditure, single source biologics that have been on the market for at least eleven years covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” under the law (the Medicare Drug Price Negotiation Program), and (ii) imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions began to take effect progressively in fiscal year 2023. On August 15, 2024, HHS announced the agreed-upon reimbursement prices of the first ten drugs that were subject to price negotiations, although the Medicare Drug Price Negotiation Program is currently subject to legal challenges. On January 17, 2025, HHS selected fifteen additional products covered under Part D for price negotiation in 2025. Each year thereafter more Part B and Part D products will become subject to the Medicare Drug Price Negotiation Program. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights that for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.

We may be unable to comply with the applicable continued listing requirements of The Nasdaq Global Select Market.*
Previous report
Our common stock is currently listed on The Nasdaq Global Select Market (Nasdaq). In order to maintain this listing, we must satisfy minimum financial and other continued listing requirements and standards, including a minimum closing bid price requirement for our common stock of $1.00 per share. In January 2025, we received a letter from The Nasdaq Stock Market advising us that for 33 consecutive trading days preceding the date of the letter, the bid price of our common stock had closed below the $1.00 per share minimum price required for continued listing on Nasdaq, and therefore we could become subject to delisting if our common stock does not meet the $1.00 minimum bid price for 10 consecutive trading days within the 180-day period following the date of the letter. We completed a reverse stock split of our common stock by a ratio of 1-for-20, effective May 30, 2025 (Reverse Stock Split). On June 16, 2025, we received a letter from Nasdaq advising us that we had regained compliance with the minimum bid price required for continued listing by Nasdaq because the closing price of our common stock closed at $1.00 or more for over 10 consecutive trading days. Although we regained compliance with the $1.00 minimum bid price requirement, there can be no assurance that we will be able to maintain compliance with the minimum bid price requirement or the other requirements for continued listing on Nasdaq.
Previous report
If we are ultimately not able to maintain compliance with Nasdaq’s continued listing requirements, our common stock will be subject to delisting. In the event that our common stock is delisted from Nasdaq and is not eligible for quotation or listing on another market or exchange, trading of our common stock could be conducted only in the over-the-counter market. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further. A delisting could also adversely affect the market liquidity of our common stock as a result of the loss of market efficiencies associated with Nasdaq and the loss of federal preemption of state securities laws, materially adversely affect our ability to obtain financing on acceptable terms, if at all, and may result in the potential loss of confidence by investors, suppliers, partners and employees and fewer business development opportunities.
Previous report
Our agreements with third parties may include indemnification provisions under which we agree to indemnify them for losses suffered or incurred as a result of claims of intellectual property infringement or other liabilities relating to or arising from our contractual obligations. Large indemnity payments could harm our business and financial condition. Although we normally contractually limit our liability with respect to such obligations, we may still incur substantial liability. Any dispute with a third party with respect to such obligations could have adverse effects on our relationship with that third party and relationships with other existing or new partners, harming our business.

We have limited resources and we expect to need to expend substantial resources for the foreseeable future to advance and expand our research pipeline, conduct nonclinical studies and pursue clinical development and manufacturing of our product candidates. We also expect to continue to expend resources for the development of our technology platforms. These expenditures will include costs associated with research and development, acquiring or licensing new technologies, conducting nonclinical studies and clinical trials and potentially obtaining regulatory approvals and manufacturing products, as well as marketing and selling products approved for sale, if any. We will also need to make significant expenditures to develop a medical affairs organization for medical education and a commercial organization capable of sales, marketing and distribution for any products, if any, that we intend to sell ourselves in the markets in which we choose to commercialize. In addition, we may be required to make success payments and other contingent consideration payments under our license, collaboration and other agreements. Because the design and outcome of our planned and anticipated clinical trials are highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the discovery, development and commercialization of our existing and potential product candidates, and other unanticipated costs may arise. Our current resources may be insufficient to support or complete the discovery, development and commercialization of our existing and potential product candidates.

As a result of expense timing, as well as diligent expense management, we believe that our existing cash, cash equivalents and marketable securities, including the net proceeds we received from the initial closing under the SPA in July 2025, will be sufficient to meet our working capital and capital expenditure needs into 2027. However, our future capital requirements and the period for which our existing resources will support our operations may vary significantly from what we expect, and we will in any event require additional capital to complete clinical development of any of our current programs.

We do not have any committed external source of funds. Additional funds may not be available when we need them on terms that are acceptable to us, or at all, and our ability to raise additional capital may be adversely impacted by potentially unfavorable global economic conditions or conditions in the biotechnology sector of the market, including disruptions to, or volatility in, the credit and financial markets in the United States and worldwide, actual or perceived changes in interest rates and economic inflation, the current or anticipated impact of geopolitical instability and otherwise. If adequate funds are not available to us on a timely basis, including pursuant to the Sales Agreement or the SPA, we may be required to delay, limit, reduce or terminate nonclinical studies, clinical trials or other development activities for our product candidates or delay, limit, reduce or terminate our establishment of sales, marketing and distribution capabilities or other activities that may be necessary to commercialize our product candidates.

In February 2024, we entered into the Sales Agreement with TD Cowen, acting as our sales agent, pursuant to which we may offer and sell shares of our common stock having an aggregate offering price of up to $150.0 million from time to time in a series of one or more at‑the‑market equity offerings. Neither we nor TD Cowen are obligated to sell any shares. As of March 31, 2026, we have sold 65,092 shares of our common stock under the Sales Agreement. If adequate funds are not available to us on a timely basis, including pursuant to the Sales Agreement, we may be required to delay, limit, reduce or terminate nonclinical studies, clinical trials or other development activities for our product candidates or delay, limit, reduce or terminate our establishment of sales, marketing and distribution capabilities or other activities that may be necessary to commercialize our product candidates.

We operate in a rapidly evolving field and, having commenced operations in June 2018, have a limited operating history, which make it difficult to evaluate our business and prospects. Our primary activities to date have included clinical development of T‑cell therapies, conducting research and development, acquiring technology, entering into strategic collaboration and license agreements, enabling and executing manufacturing activities in support of our product candidate development efforts, executing clinical trials, organizing and staffing the company, business planning, establishing our intellectual property portfolio, regulatory submissions and other preparations to initiate and execute clinical trials, raising capital and providing general and administrative support for these activities. Any predictions about our future success, performance or viability may not be as accurate as they could be if we had a longer operating history or approved products on the market.

In connection with the Agreement and Plan of Merger, dated as of October 24, 2024, by and among Lyell, ImmPACT, Inspire Merger Sub Inc. and WT Representative LLC, solely in its capacity as the Representative (the Merger Agreement), we agreed to issue additional shares of our common stock upon the achievement of certain ronde-cel clinical or regulatory milestones and to make certain cash royalty payments to the pre-closing stockholders of ImmPACT based on future annual net sales of ronde-cel in the United States. In July 2025, we issued 625,000 shares of our common stock to the pre-closing stockholders of ImmPACT as a result of the achievement of certain ronde-cel clinical milestones. In addition, as a result of the acquisition of ImmPACT, we have assumed ImmPACT’s rights and obligations under the license agreement with UCLA (UCLA License Agreement), pursuant to which we are obligated to pay a nominal, tiered annual license maintenance fee, one-time milestone payments for each commercialized licensed product and a tiered royalty on worldwide annual net sales of commercialized licensed products. For information related to our milestone and royalty obligations, see Note 3, Contingent Consideration Payable and Royalty Payments, in the accompanying notes to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10‑Q.

We also agreed to make success payments payable in cash or publicly-tradeable shares of our common stock at our discretion pursuant to our success payment agreements with Fred Hutch and Stanford, pursuant to which we may be required to make success payments based on increases in the per share fair value of our common stock on each contractually prescribed measurement date. Our success payment obligations are recorded as liabilities on our condensed consolidated balance sheets. Under GAAP, we are required to estimate the fair value of these liabilities as of each quarter end and changes in the estimated fair value are accreted to research and development expense over the service period of the collaboration agreement. Once the requisite service obligation to earn the potential success payment consideration is met under our continued collaboration agreements, the change in the success payment liabilities fair value is recognized in other income or expense, net. For example, in December 2022 and September 2024, Fred Hutch and Stanford, respectively, had provided the requisite service obligation to earn the potential success payment consideration under the continued collaboration; accordingly in future periods, the change in the success payments liability fair value is recognized in other income or expense, net. Factors that may lead to increases or decreases in the estimated fair value of our success payment liabilities include, among others, changes in the value of the common stock, changes in volatility and changes in the risk-free rate. For information related to our success payment obligations, see Note 4, License, Collaboration and Success Payment Agreements, in the accompanying notes to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10‑Q.

Under the Tax Cuts and Jobs Act of 2017 (the Tax Act), as modified by the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act), our net operating losses (NOLs) generated in tax years beginning after December 31, 2017 may be carried forward indefinitely, but the deductibility of such federal NOLs is limited to 80% of taxable income. There is variation in how states have responded and may continue to respond to the Tax Act and CARES Act. In addition, under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” generally defined as a greater than 50 percentage point change (by value) in its equity ownership by certain stockholders over a three-year period, the corporation’s ability to use its pre-change NOLs and other pre-change tax attributes (such as research and development tax credits) to offset its post-change income or taxes may be limited. We may have experienced ownership changes in the past, including as a result of our initial public offering (IPO), and may experience future ownership changes as a result of subsequent shifts in our stock ownership (some of which may be outside our control). As a result, our ability to use our pre-change NOLs and tax credits to offset post-change taxable income, if any, could be subject to limitations. Similar provisions of state tax law may also apply. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. As a result, even if we attain profitability, we may be unable to use a material portion of our NOLs and tax credits.

We currently have two product candidates in clinical development. Our lead product candidate, ronde-cel, is under evaluation in the pivotal PiNACLE trial in the 3L+ setting and in the Phase 1/2 clinical trial in the 2L setting. A second pivotal trial, PiNACLE - H2H, which is a Phase 3 head-to-head CAR T‑cell therapy randomized controlled trial of ronde-cel for LBCL in the 2L setting, is expected to begin enrolling by early 2026. LYL273, a novel GCC-targeted CAR T-cell product candidate, is under evaluation in a U.S. Phase 1 dose-escalation, dose-expansion clinical trial in patients with refractory mCRC. We have not yet demonstrated our ability to successfully complete any clinical trials (including any pivotal clinical trials), obtain regulatory 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, and we have previously discontinued clinical development programs. We have invested substantial resources in developing our technology platforms and our product candidates, conducting nonclinical studies, commencingand conducting clinical trials and building our manufacturing facilities and capabilities, each of which will be required prior to any regulatory approval and commercialization. Our ability to generate revenue from product sales, which we do not expect will occur for several years, if ever, will depend heavily on the successful research and development and eventual commercialization of one or more product candidates in profitable indications and markets. The success of our efforts to identify, develop, manufacture and commercialize product candidates will depend on many factors, including the following:

We are seeking to identify and develop a pipeline of product candidates using our proprietary technology platforms. The scientific research that forms the basis of our efforts to develop product candidates with our technology platforms is still ongoing. Further, the scientific evidence to support the feasibility of developing therapeutic treatments based on our technology platforms is both preliminary and limited. Additionally, although ronde‑cel is in the pivotal PiNACLE trial in the 3L+ setting and Phase 1/2 clinical development in the 2L setting, our current clinical data are limited, and nonclinical data from murine tumor models and in vitro experiments with tumor cell lines may not translate into humans or may not accurately predict the safety and efficacy of our product candidates in humans. As a result, we are exposed to a number of unforeseen risks, and it is difficult to predict the types of challenges and risks that we may encounter during development of our product candidates. Although we have presented clinical data from the multi‑center Phase 1/2 trial of ronde‑cel, including data from patients with relapsed and/or refractory LBCL, our ronde‑cel clinical trials, including the pivotal PiNACLE trial and PiNACLE – H2H, may not generate similar results or otherwise provide adequate data to demonstrate the efficacy and safety of our product candidate.

Given the novelty of our technology platforms, 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, the regulatory pathway with the FDA and comparable foreign regulatory authorities may be more complex and time-consuming relative to other more well-known therapeutics. Even if we obtain human data to support our product candidates, the FDA or comparable foreign regulatory authorities may lack sufficient experience in evaluating the safety and efficacy of our product candidates developed using our technology platforms, which could result in a longer than expected regulatory review process, increase our expected development costs and delay or prevent commercialization of our product candidates. The validation process takes time and resources, may require independent third-party analyses and may not be accepted or approved by the FDA and comparable foreign regulatory authorities. There can be no assurance as to the length of clinical development, the number of patients that the FDA or comparable foreign regulatory authorities may require to be enrolled in clinical trials to establish the safety, purity and potency of our product candidates or the acceptability to the FDA or comparable foreign regulatory authorities of data generated in these clinical trials to support marketing approvals. We cannot be certain that our approach will lead to the development of approvable or marketable products, alone or in combination with other therapies.

The results of research, nonclinical studies or earlier clinical trials are not necessarily predictive of future results, initial clinical results in a clinical trial may not be predictive of future results in the same clinical trial and results in one indication may not be predictive of results to be expected for the same product candidate in another indication. If clinical trials of our product candidates fail to produce positive results or demonstrate satisfactory safety and efficacy, at the appropriate dose level or at all, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates. Any product candidate we advance into clinical trials may not have favorable results in later clinical trials or receive regulatory approval.*

Success in research, nonclinical studies and early clinical trials does not ensure that later clinical trials will generate similar results and otherwise provide adequate data to demonstrate the efficacy and safety of an investigational product. Clinical trials may show that one or more of our product candidates are not safe or effective, in which event we may need to abandon development of such product candidates. In fact, a number of companies in the pharmaceutical and biotechnology industries, including those with greater resources and experience than us, have suffered significant setbacks in early- and late-stage clinical trials, even after seeing promising results in earlier nonclinical studies or clinical trials. Thus, even if the results from our initial research, nonclinical activities or early clinical results appear positive, we do not know whether the current pivotal PiNACLE trial in the 3L+ setting, PiNACLE – H2H in the 2L setting, the Phase 1/2 clinical trial in the 2L setting for ronde‑cel, the Phase 1 clinical trial for LYL273 in patients with refractory mCRC or subsequent clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market ronde-cel or LYL273. Although we presented clinical data from the multi‑center Phase 1/2 trial of ronde‑cel, including data from patients with relapsed and/or refractory LBCL, such results may not be predictive of future results in our ronde‑cel clinical trials, including the pivotal PiNACLE trial and the PiNACLE – H2H trial.

The risk of failure of our product candidates, or any product candidates we acquire, is high. The clinical trials and manufacturing of our product candidates, or any product candidates we acquire, are, and the manufacturing and marketing of such product candidates, if approved, will be, subject to extensive and rigorous review and regulation by numerous government authorities in the United States and in other countries where we intend to test and market our product candidates. Before obtaining regulatory approvals for the commercial sale of any of our product candidates, we must demonstrate through lengthy, complex and expensive nonclinical testing and clinical trials that our product candidates are both safe and effective for use in each target indication. In particular, because our product candidates are subject to regulation as biological products, we will need to demonstrate that they are safe, pure and potent for use in their target indications. Each product candidate must demonstrate an adequate risk versus benefit profile in its intended patient population and for its intended use.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign regulatory authority. As a result of safety or toxicity issues that we may experience in our clinical trials, we may not continue the development of nor receive approval to market any product candidates, which could prevent us from ever generating product revenues or achieving profitability. Previous clinical trials utilizing CAR T cells to treat hematologic malignancies have shown an increased risk of CRS and ICANS, and approved CAR T-cell therapy products carry a boxed warning concerning the risk of developing secondary T‑cell malignancies. For example, while we observed a manageable safety profile appropriate for outpatient administration, initial data from patients with LBCL treated in the 3L+ setting and the 2L setting in our ongoing multi-cohort, multi-center Phase 1/2 clinical trial of ronde-cel reported low rates of Grade>3 ICANS. In addition to CRS and ICANS, diarrhea or colitis have been reported with LYL273. Adverse events may also be associated with the lymphodepletion utilized with cellular therapies. If additional adverse events or other side effects are observed in any of our clinical trials that are atypical of, or more severe than, the known side effects of similar cell therapies, we may have difficulty recruiting patients to our clinical trials, patients may drop out of our trials or we may be required to abandon those trials or our development efforts of one or more product candidates altogether. If such effects are more severe, less reversible than we expect or not reversible at all, we may decide or be required to perform additional studies or to halt or delay further clinical development of any of our product candidates, which could result in the delay or denial of regulatory approval by the FDA or other regulatory authorities.
