•We have identified a material weakness in our internal control over financial reporting. If our remediation of the material weakness is not effective, or if we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

Current wording

•We previously identified a material weakness in our internal control over financial reporting. If we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

•In December 2024, we announced initial clinical data from the Phase 1 clinical trial of our first product candidate, SENTI-202 and the first patient dosed in a clinical trial of SN301A in China under our collaboration with Celest Therapeutics, and the rest of our current product candidates are in preclinical development. One or all of our current product candidates may fail in clinical development or suffer delays that materially and adversely affect their ability to receive regulatory approval or to attain commercial viability.

Current wording

•In December 2024 and April 2025, we announced initial clinical data from the Phase 1 clinical trial of our first product candidate, SENTI-202. Also in December 2024, we announced that the first patient was dosed in a clinical trial of SN301A in China under our collaboration with Celest Therapeutics where they manufactured SN301A under their own manufacturing process, and the rest of our current product candidates are in preclinical development. In April 2025, Celest Therapeutics decided to stop dosing in its SN301A clinical trial due to dose limiting toxicities observed. Other product candidates may also fail in clinical development or suffer delays that materially and adversely affect their ability to receive regulatory approval or to attain commercial viability.

•If we decide to seek orphan drug designation for one or more of our product candidates, we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation for our current or future product candidates that we may develop.

Current wording

•Despite receiving orphan drug designation for SENTI-202 for one indication, if we decide to seek orphan drug designation for one or more of our other product candidates, we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation for our current or future product candidates that we may develop.

Previous wording

We are an early clinical stage biotechnology company with a history of losses. Since our inception, we have devoted substantially all of our resources to research and development, preclinical studies, building our management team and building our intellectual property portfolio, and we have incurred significant operating losses. Our net losses were $52.8 million and $71.1 million for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024 , we had an accumulated deficit of $297.1 million. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. To date, we have not generated any revenue from product sales, and we have not sought or obtained regulatory approval for any product candidate. Furthermore, we do not expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, preclinical studies, clinical trials, manufacturing and the regulatory approval process for our current and potential future product candidates.

The development of biotechnology product candidates is capital-intensive. If any of our current or potential future product candidates enter and advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, marketing and sales capabilities. We have used substantial funds to develop our gene circuit platform, SENTI-202, SENTI-301A, and other potential product candidates, and we will require significant funds to continue to develop our platform and conduct further research and development, including preclinical studies and clinical trials. In addition, we expect to incur significant additional costs associated with operating as a public company.

As of December 31, 2024, we had $48.3 million in cash and cash equivalents. In connection with the preparation of this Form 10-K, our management has concluded that there is substantial doubt as to whether we can continue as a going concern for twelve months following the filing of this Form 10-K. Our future capital requirements and the period for which our existing resources will support our operations may vary significantly from what we expect. Our monthly spending levels vary based on new and ongoing research and development and other corporate activities. Because the length of time and activities associated with successful research and development of platform technologies and product candidates are highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. Our future capital requirements and the timing and amount of our operating expenditures will depend largely on:

Current wording

As of December 31, 2025, we had $16.4 million in cash and cash equivalents. In connection with the preparation of this Annual Report, our management has concluded that there is substantial doubt as to whether we can continue as a going concern for 12 months following the filing of this Annual Report and that without additional financing, we may not be able to continue operations as planned past the second quarter of 2026. Our future capital requirements and the period for which our existing resources will support our operations may vary significantly from what we expect. Our monthly spending levels vary based on new and ongoing research and development and other corporate activities. Because the length of time and activities associated with successful research and development of platform technologies and product candidates are highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. In addition, though we have reached agreement with GeneFab regarding the repayment of overdue payments from GeneFab under various agreements with GeneFab, a substantial amount of that repayment is expected to be in kind in exchange for various manufacturing services and not in cash. Our inability to collect all amounts owing from GeneFab in cash has negatively impacted our ability to continue as a going concern. If GeneFab fails to pay amounts owing to us in the future, our business will be substantially harmed further.

Previous wording

We cannot assure you that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms acceptable to us, if at all. If we are unable to obtain adequate financing when needed, our business, financial condition and results of operations will be harmed, and we may need to significantly modify our operational plans, or else we will not be able to continue as a going concern beyond twelve months from the issuance date of this Form 10-K. For example, in January 2023 we announced a strategic plan to focus internal resources on SENTI-202 and SENTI-401, to develop gene circuits for other programs with potential partners, and to suspend internal research and development efforts for SENTI-301A. In August 2023, we announced a transaction with GeneFab pursuant to which we transferred our in-house manufacturing operations and assets to GeneFab. In January 2024, we announced a strategic plan to focus our resource allocation to investment in clinical development of SENTI-202 and on partnership of our SENTI-301A program in China. In September 2024, we subleased to BKBIOTECH, Inc., and JLSA2 Therapeutics, Inc., certain portions of our corporate headquarters. In the future, we may have to delay, reduce the scope of or suspend one or more of our preclinical studies, clinical trials, research and development programs, or commercialization efforts. Further, if we are unable to continue as a going concern, we might have to liquidate our assets, and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. Because of the numerous risks and uncertainties associated with the development and commercialization of our current and potential future product candidates and the extent to which we may enter into collaborations with third parties to participate in their development and commercialization, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated preclinical studies and clinical trials, including related manufacturing costs.

We have had to delay certain work under planned statements of work (“SOWs”) with GeneFab due to a lack of funding in the past. We have plans to further engage GeneFab to perform work under these and new SOWs. However, there can be no assurance that we will have the funding available to us to do so. In January 2024, we announced a strategic plan to focus our resource allocation to investment in clinical development of SENTI-202 and on partnership of our SENTI-301A program in China which we have subsequently ceased developing.

Previous wording

As previously reported, in connection with our preparation and the audit of our consolidated financial statements as of and for the year ended December 31, 2023, we and our independent registered public accounting firm identified a material weakness, as defined under the Exchange Act and by the Public Company Accounting Oversight Board (United States), in our internal control over financial reporting. The material weakness related to a lack of sufficient and adequate resources in the finance and accounting function that resulted in ineffective process level control activities over non-routine, unusual or complex transactions.

Current wording

As previously reported, in connection with our preparation and the audit of our consolidated financial statements as of and for the year ended December 31, 2024, we and our independent registered public accounting firm identified a material weakness, as defined under the Exchange Act and by the Public Company Accounting Oversight Board (United States), in our internal control over financial reporting. The material weakness related to a lack of sufficient and adequate resources in the finance and accounting function and while we remediated the material weakness in 2025, there can be no assurance that we will not have another material weakness in our finance and accounting functions.

Previous wording

We implemented a risk assessment process and measures designed to improve our internal control over financial reporting and remediate the control deficiencies that led to the material weakness, including hiring additional accounting personnel, but have had additional turnover in our accounting group since that time which continues to harm these remediation efforts. However, the process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. Moreover, the rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing, and remediation. To maintain and improve the effectiveness of our financial reporting, we will need to commit significant resources, implement and strengthen existing disclosure processes controls, reporting systems, and procedures, train personnel and provide additional management oversight, all of which may divert attention away from other matters that are important to our business.

We cannot be certain that the measures we have taken to date, and actions we may take in the future, will be sufficient to remediate the control deficiencies that led to our material weakness in our internal control over financial reporting or that they will prevent or avoid potential future material weaknesses. In addition, an independent registered public accounting firm has not yet performed an evaluation of our internal control over financial reporting, though such an evaluation will be required when we lose our status as an “emerging growth company” and become an “accelerated filer” or a “large accelerated filer.” When an evaluation by an independent registered public accounting firm is performed, such firm may issue a report that is qualified if it is not satisfied with our controls or the level at which our controls are documented, designed, operated, or reviewed.

If we are not able to implement the requirements of Section 404 in a timely manner or with adequate compliance, our independent registered public accounting firm when required may issue an adverse opinion due to ineffective internal controls over financial reporting, and we may be subject to sanctions or investigation by regulatory authorities, such as the SEC. As a result, there could be a negative reaction in the financial markets due to a loss of confidence in the reliability of our consolidated financial statements. In addition, we may be required to incur costs in improving our internal control system and the hiring of additional personnel. Any such action could negatively affect our results of operations and cash flows.

Our NOLs could expire unused and be unavailable to offset future income tax liabilities because of their limited duration or because of restrictions under U.S. tax law. NOLs generated in taxable years beginning before January 1, 2018 are permitted to be carried forward for 20 taxable years under applicable U.S. federal income tax law. Under current U.S. federal income tax law, NOLs arising in tax years beginning after December 31, 2020 may not be carried back. Moreover, NOLs generated in taxable years beginning after December 31, 2017 may be carried forward indefinitely, but the deductibility of such NOLs generally will be limited in taxable years beginning after December 31, 2020 to 80% of current year taxable income. As of December 31, 2024, we had NOLs for U.S. federal and state income tax purposes of approximately $191.8 million and $152.9 million, respectively, a portion of which expire beginning in 2036 if not utilized.

Pursuant to an option under the transaction with GeneFab which was subsequently transferred to Celadon Partners, Celadon may choose to invest up to approximately $20 million to purchase up to 1,963,344 shares of our common stock, subject to certain limitations, including stockholder approval in certain circumstances and compliance with applicable law. The option becomes exercisable by Celadon upon the execution of the license agreement, no later than August 7, 2026. The exercise of the option by Celadon could result in a significant increase in the number of outstanding shares of our common stock and substantially dilute the ownership interest of our existing stockholders. In addition, we have agreed to register for resale these shares purchased by Celadon under their option, subject to certain restrictions. If Celadon chooses to sell its shares in the Company, the price of our shares could fluctuate based on the market price of the common stock during the period in which such sales occur. Additionally, the sale of a substantial number of shares of our common stock, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

Events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. As of December 31, 2024, we held a letter of credit with JPMorgan Chase Bank in the amount of approximately $2.9 million related to the Alameda facility and a letter of credit with JPMorgan Chase Bank in the amount of approximately $0.5 million related to our headquarter facility leases. As of the date of this Form 10-K, we hold certain funds in accounts with Silicon Valley Bank, or SVB. Due to the placement into receivership of SVB in March 2023, we may be unable to access such funds. In addition, if any parties with whom we conduct business are unable to access funds pursuant to instruments or lending arrangements with such a financial institution, such parties’ ability to pay their obligations to us or to enter into new commercial arrangements requiring additional payments to us could be adversely affected. In this regard, counterparties to credit agreements and arrangements with banks in receivership or other financial difficulty, and third parties (such as beneficiaries of letters of credit, among others), may experience direct impacts from the closure of or reorganization of such financial institution and uncertainty remains over liquidity concerns in the broader financial services industry. Similar impacts have occurred in the past, such as during the 2008-2010 financial crisis.

Previous wording

We have no products on the market or that have gained regulatory approval and we are just beginning the clinical development of SENTI-202, our lead product candidate. Our ability to achieve and sustain profitability depends on obtaining regulatory approvals for and successfully commercializing product candidates, either alone or with collaborators.

Current wording

We have no products on the market or that have gained regulatory approval and we are in the early stages of the clinical development of SENTI-202, our lead product candidate.

Previous wording

Other than SENTI-202 and SENTI-301A, none of our current product candidates have ever been tested in humans. We may ultimately discover that our current product candidates do not possess certain properties that we believe are helpful for therapeutic effectiveness and safety or would otherwise support the submission of an IND on the timelines we expect, or at all. In early clinical trials with the Celest Therapeutics’ SN301A program which incorporates our SENTI 301A gene circuit, our partner, Celest Therapeutics has observed certain dose limiting toxicities in some patients and is currently evaluating dosing levels below those that resulted in such toxicities that may or may not result in a meaningful clinical effect. We also do not know if the observations we have made regarding our gene circuits generally and our product candidates in particular will translate into any clinical response when tested in humans. As an example, while the TAA CD33 has been clinically validated as a target for an approved antibody-drug conjugate therapy, it has not been clinically validated as a target for CAR-NK or CAR-T therapies, and may not prove to be a clinically sufficient target for the CAR-NK therapies we are developing. As a result of these uncertainties related to our gene circuit platform technologies and our product candidates, we may never succeed in developing a marketable product based on our current product candidates. If any of our current or potential future product candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Previous wording

Undesirable side effects caused by any of our current or potential future product candidates could cause 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 regulatory authorities. We announced initial results from the Phase 1 clinical trial for SENTI-202 and our partner Celest Therapeutics initiated clinical trials for SN-301A in China, and have not initiated clinical trials for any other product candidates. It is likely that there will be side effects associated with the use of certain of our products. For example, we have seen dose limiting toxicities in early results from Celest Therapeutics’ clinical trial of SN-301A and are evaluating different dosing levels for that product candidate. Further, if the NOT GATE gene circuit, engineered into one of our product candidates, such as SENTI-202, does not provide a clinically sufficient level of inhibition, it may kill healthy cells that it has been designed to preserve or may cause systemic immune cytotoxicity. It is possible that safety events or concerns such as these or others could negatively affect the development of our product candidates, including adversely impacting patient enrollment among the patient populations that we intend to treat. In such an event, our trials could be suspended or terminated, and the FDA or other regulatory authorities could order us to cease further development of or deny approval of a product candidate for any or all targeted indications. Such side effects could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. To date, we have not observed any such effects in our preclinical studies, but there can be no guarantee that our current or future product candidates will not cause such effects in clinical trials. Any of these occurrences may materially and adversely impact our business and financial condition and impair our ability to generate revenues.

A key element of our strategy is to use and advance our gene circuit platform to design, test and build our portfolio of product candidates focused on allogeneic gene circuit-equipped CAR-NK cell therapies for the treatment of cancer. Although our research and development efforts to date have resulted in our discovery and preclinical development of SENTI-202, SENTI-301A, and other potential product candidates, we only received clearance of our IND for SENTI-202 in December 2023, and initiated our Phase 1 clinical trial for SENTI-202 in the second quarter of 2024 and announced initial results from the Phase 1 clinical trial for SENTI-202 in the fourth quarter of 2024 and have begun dosing in a clinical trial for SN-301A in a collaboration led by Celest Therapeutics in China in December 2024, and to date have not tested any other product candidates in humans. We cannot assure you that any other existing product candidates will advance to clinical trials or, if they do, that such trials will demonstrate these product candidates to be safe or effective therapeutics, and we may not be able to successfully develop any product candidates. Even if we are successful in expanding our pipeline of product candidates, any additional product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue in the future.

In addition, our partner in China, Celest Therapeutics, began dosing in a clinical trial for SN-301A in December 2024 but stopped dosing in that trial in April 2025 due to certain dose limiting toxicities observed in that clinical trial. We have not tested any other products in humans and we cannot assure you that any other existing product candidates will advance to clinical trials or, if they do, that such trials will demonstrate these product candidates to be safe or effective therapeutics, and we may not be able to successfully develop any product candidates.

If we decide to seek orphan drug designation for one or more of our product candidates, we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation for our current or future product candidates that we may develop.

Current wording

Despite receiving orphan drug designation for SENTI-202 for one indication, if we decide to seek orphan drug designation for one or more of our other product candidates, we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation for our current or future product candidates that we may develop.

Previous wording

Under the Orphan Drug Act, the FDA may designate a product candidate as an orphan drug if it is a drug or biologic product intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or where there is no reasonable expectation that the cost of developing the product will be recovered from sales in the United States. We may seek orphan drug designation for certain indications for our product candidates in the future. Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. Orphan drug designation can entitle a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers.

There can be no assurance that we will achieve all of the anticipated benefits of the transaction with GeneFab and we could face unanticipated challenges.

Current wording

There can be no assurance that we will achieve all of the anticipated benefits of the transactions with GeneFab and we could face unanticipated challenges.

Previous wording

We may not realize some or all of the anticipated benefits from the transaction with GeneFab and we may encounter post-closing risks. For example, the conditions for our receipt of the deferred consideration payable to us under the Framework Agreement, dated August 7, 2023, by and among us, GeneFab and Valere Bio, Inc. (“Valere”) may not be achieved on the timelines we anticipate, or at all, which could adversely affect our business, financial conditions, cash flow, and results of operations. In addition, the conditions for our receipt of proceeds under the Seller Economic Share Agreement, dated August 7, 2023, by and among us, GeneFab and Valere also may not be achieved. Furthermore, disagreements with GeneFab over these obligations could require or result in litigation or arbitration, which would be time-consuming and expensive. Any of these events could have a material adverse effect on our ability to develop and commercialize any of our product candidates and may adversely impact our business, prospects, financial condition, and results of operations.

Current wording

We may not realize some or all of the anticipated benefits from the transactions with GeneFab and we may encounter post-closing risks. On March 17, 2026 we entered into a First Amendment to Lease, a First Amendment to Sublease, a First Amendment to Landlord’s Consent to Sublease and a Letter Agreement all related to the Alameda Facility, pursuant to which GeneFab paid cash for certain outstanding, overdue rent amounts and agreed to provide prepaid manufacturing credits to Senti for the remaining outstanding, overdue rent payments. If GeneFab fails to pay ongoing rent for the Alameda Facility, we could be required to evict GeneFab from the Alameda Facility and GeneFab would be unable to perform its obligations under the Development and Manufacturing Services Agreement (“DMSA”). This could materially impact our ability to develop and commercialize any of our product candidates and may adversely impact our business, prospects, financial condition, results of operations and clinical operations. In addition, this non-payment or any other disagreements with GeneFab over its obligations to us could require or result in litigation or arbitration, which would be time-consuming and expensive and could also have a material adverse effect on our ability to develop and commercialize any of our product candidates and may adversely impact our business, prospects, financial condition, and results of operations.

Previous wording

We depend on strategic partnerships and collaboration arrangements, such as our collaboration arrangements with Spark Therapeutics, Inc., or Spark, BlueRock Therapeutics, Inc., or BlueRock, and Celest Therapeutics , for the application of our gene circuit platform technology to the development and commercialization of potential product candidates in certain indications, and if these arrangements are unsuccessful, this could impair our ability to generate revenues and materially harm our results of operations.

In the past, we have depended on strategic partnerships and collaboration arrangements, such as our collaboration arrangements with BlueRock Therapeutics, Inc., or BlueRock, and Celest Therapeutics, for the application of our gene circuit platform technology to the development and commercialization of potential product candidates in certain indications, and if these arrangements are unsuccessful, this could impair our ability to generate revenues and harm our results of operations.

Previous wording

Our business strategy for exploiting the potential of our gene circuit platform technology is dependent upon maintaining our current arrangements and establishing new arrangements with strategic partners, research collaborators and other third parties. We currently have collaboration agreements with Spark, BlueRock and Celest. These collaboration agreements provide for, as the case may be, among other things, research funding and significant future payments to us from our collaborators should certain development, regulatory and commercial milestones be achieved. Under these arrangements, our collaborators are typically responsible for, in the applicable territories and fields:

As a result, we may not be able to conduct these collaborations in the manner or on the time schedule we currently contemplate, which may negatively impact our business operations.

Current wording

As a result, we may not be able to conduct these collaborations in the manner or on the time schedule we currently contemplate, which may negatively impact our business operations. For example, Celest has determined that it will not move forward with its clinical trial of SN301A, a product that incorporates some of our technology. In addition, Spark did not exercise its option to continue pursuing the products under collaboration with them. If other collaborations result in similar outcomes, our ability to generate revenue could be harmed.

Previous wording

Additionally, the development and commercialization of potential product candidates under our collaboration agreements could be substantially delayed, and our ability to receive future funding could be substantially impaired if one or more of our collaborators:

We do not have our own manufacturing facilities or personnel and currently rely, and expect to continue to rely, on third party manufacturing organizations, or CMOs, and in particular GeneFab, for the manufacture of our current or future product candidates. Under our Development and Manufacturing Services Agreement with GeneFab, we are obligated to engage GeneFab for certain manufacturing services subject to GeneFab’s meeting of certain criteria. GeneFab and any other CMO may not be able to provide adequate resources or capacity to meet our needs. If GeneFab or any other CMO with whom we contract fails to perform its obligations, we may be forced to enter into an agreement with a different CMO, which we may not be able to do on reasonable terms, if at all. This could significantly delay our clinical trials supply as we establish alternative supply sources and the shift to a different CMO could be expensive. In some cases, the technical skills required to manufacture our product candidates or products, if approved, may be unique or proprietary to the original CMO and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills to a back-up or alternate supplier, or we may be unable to transfer such skills at all. In addition, if we are required to change CMOs for any reason, we will be required to verify that the new CMO maintains facilities and procedures that comply with quality standards, our product specifications and all applicable regulations.

Current wording

We do not have our own manufacturing facilities or personnel and currently rely, and expect to continue to rely on CMOs, and in particular GeneFab, for the manufacture of our current or future product candidates. Under our DMSA with GeneFab, we are obligated to engage GeneFab for certain manufacturing services subject to GeneFab’s meeting of certain criteria. Currently, we do not have relationships with CMOs beyond GeneFab for the majority of our product manufacturing needs and even if we were to establish those relationships, other CMOs may not be able to provide adequate resources or capacity to meet our needs. If GeneFab or any other CMO with whom we contract fails to perform its obligations, we may be forced to enter into an agreement with a different CMO, which we may not be able to do in a timely manner or on reasonable terms, if at all. In addition, if we are required to evict GeneFab from its current space for non-payment under the GeneFab subleases, our clinical trial timelines could be adversely affected due to disruptions in manufacturing supply, and transitioning to an alternative contract manufacturing organization may result in delays and increased costs. In some cases, the technical skills required to manufacture our product candidates or products, if approved, may be unique or proprietary to the original CMO and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills to a back-up or alternate supplier, or we may be unable to transfer such skills at all.

Initial manufacturing efforts under our agreements with GeneFab will focus on our lead program, SENTI-202. GeneFab has never operated a cGMP facility before. GeneFab may not have the ability to consistently and reliably manufacture SENTI-202 in sufficient quality and quantity to support our ongoing and planned clinical trials, which could negatively impact our overall development timelines. In addition, quality, reproducibility, stability, and consistency issues may arise during manufacturing activities and may result in lower yields than initially expected. We do not currently have arrangements in place for a redundant or second-source supply in the event the facility we sublease to GeneFab is not operational or GeneFab is otherwise unable to meet our supply requirements for our preclinical studies and planned clinical trials. Any delays in manufacturing our product candidates could impede, delay, limit or prevent our drug development efforts, which could harm our business, results of operations, financial condition and prospects.

Previous wording

In order to conduct clinical trials for our current and potential future product candidates or to commercialize any approved product candidates, we will need to manufacture large quantities of these product candidates. We currently rely exclusively on GeneFab to produce required quantities of SENTI-202. We, GeneFab, or any future manufacturing partners, may be unable to successfully scale-up the manufacturing process or to otherwise increase capacity for any current or potential future product candidate in a timely or cost-effective manner, or at all. In addition, quality, reproducibility, stability, consistency issues may arise during scale-up activities and may result in lower yields than initially expected. While we believe GeneFab will be able to sufficiently scale to produce quantities of SENTI-202 and future product candidates required to advance our preclinical studies and clinical trials, any significant revisions to the manufacturing process may create delays, which could negatively impact our overall development timelines.

Work performed by GeneFab for us represents the large majority of work GeneFab currently performs at its facilities, which are subleased by us to GeneFab. If GeneFab is unable to continue performing work for us or pay us under its sublease, as amended, for our Alameda Facility or if we are required to evict GeneFab from our Alameda facility for nonpayment of rent, we could be substantially harmed. On March 17, 2026 we entered into a First Amendment to Lease, a First Amendment to Sublease, a First Amendment to Landlord’s Consent to Sublease and a Letter Agreement all related to the Alameda Facility, pursuant to which GeneFab paid cash for certain outstanding, overdue rent amounts and agreed to provide prepaid manufacturing credits to Senti for the remaining outstanding, overdue rent payments. As of the date of this report, GeneFab has not fully satisfied its obligations under certain other agreements with us. If GeneFab fails to pay the amounts owing under such other agreements or fails to pay ongoing rent for the Alameda Facility, we could be required to evict GeneFab from the Alameda Facility and GeneFab would be unable to perform its obligations under the Development and Manufacturing Services Agreement. If GeneFab fails to make future payments under its sublease obligations or is unable to perform its obligations under its agreements with us, we will be substantially harmed.
