Eikon Therapeutics, Inc.

Previous wording

We are a late clinical-stage biotechnology company with a limited operating history. Consequently, it may be more difficult to evaluate our business, and predictions about our future may not be as accurate as they could be if we had a longer operating history. We were formed in July 2019 and have devoted substantially all of our resources since that time to research, engineering, and development activities, including the clinical development of our clinical-stage product candidates EIK1001, EIK1003, and EIK1004, which were in-licensed, and EIK1005, and other preclinical programs, the development of our technology platform, including the engineering of the hardware, software, reagents, and processes that we use to conduct single molecule tracking and other techniques, recruiting management and technical staff, developing and establishing our intellectual property portfolio, entering into collaboration agreements to further our development programs, building our facilities, including our site in Millbrae, California, infrastructure to support such activities, and raising capital. We are currently conducting a Phase 2/3 registrational trial for EIK1001 in combination with pembrolizumab for the treatment of patients with advanced melanoma. For patients with non-small cell lung cancer, or NSCLC, we are conducting a Phase 2 trial, and recently initiated site selection for a Phase 2/3 registrational trial, for EIK1001 in combination with pembrolizumab and chemotherapy. For EIK1003, we are conducting a Phase 1/2 trial in ovarian, breast, prostate, and pancreatic cancers. We have also recently initiated Phase 1/2 trials for EIK1004 and for EIK1005. The rest of our programs remain in preclinical development.

We have incurred net losses since our inception. Net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital. For the three months ended March 31, 2026 and 2025, we reported a net loss of $83.0 million and $68.2 million, respectively. As of March 31, 2026, we had an accumulated deficit of $1.0 billion. We expect to continue to incur significant losses for the foreseeable future, and we expect these losses to increase as we continue research and development efforts for our product candidates, advance our product candidates through preclinical studies and clinical trials, and seek regulatory approvals.

Our technology platform is central to our belief that by quantitating the dynamics of proteins in their full, living, cellular context, we can improve the speed and probability of success of drug development, as well as the identification of clinically relevant biomarkers. Our technology platform is centered around our proprietary SMT system, integrating tools such as custom-engineered super-resolution microscopy, bespoke automation, advanced data science, and software packages capable of processing petabyte-scale datasets. While we believe that we can generate important scientific insights by understanding protein behavior at a molecular level inside intact living cells from human cell lines, thereby accelerating the identification of novel agents that would prove clinically valuable, EIK1005 is the only product candidate in clinical development that has leveraged our technology platform. Rights related to all other clinical-stage products candidates are in-licensed. EIK1006, which also leveraged our technology platform, is still in preclinical studies and it is possible that it may not advance to clinical trials. There can be no certainty that our technology platform will lead to the identification of clinically relevant biomarkers or additional clinical product candidates, or improve the speed and probability of success of drug development in the manner which we expect, if at all.

Previous wording

We identified a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. We did not design and maintain effective controls related to the evaluation of the accounting considerations for complex terms in lease arrangements. The material weakness resulted in the restatement of the condensed balance sheet and condensed statement of cash flows as of and for the nine months ended September 30, 2025. Additionally, this material weakness could result in misstatements to lease-related accounts or disclosures that would result in a material misstatement to the annual or interim financial statements that would not be prevented or detected.

Current wording

We identified a material weakness in our internal control over financial reporting as of December 31, 2025 with respect to the design and effectiveness of our controls related to the evaluation of the accounting considerations for complex terms in lease arrangements.

Previous wording

We are taking steps to remediate the material weakness and to strengthen our internal control over financial reporting. The material weakness will not be considered remediated until management completes the design and implementation of the controls and the controls operate for a sufficient period of time and management has concluded, through testing, that these controls are effective. The measures we will take may not be sufficient to remediate the material weakness we have identified or avoid potential future material weaknesses. If the steps we take do not remediate the material weakness in a timely manner, we will be unable to conclude that we maintain effective internal control over financial reporting. Accordingly, there could continue to be a reasonable possibility that a material misstatement of our financial statements would not be prevented or detected.

In April 2025, the current presidential administration imposed a baseline ten percent tariff on imports from all nations importing goods to the United States, with that baseline supplemented in certain cases by additional tariffs that vary by nation, product, or industry. Retaliatory tariffs on U.S. goods have been imposed by, among others, China, Canada, and the European Union, or the EU, which could impact inflation rate, increase the cost of goods, and adversely affect our business. On February 20, 2026, the U.S. Supreme Court ruled against the current presidential administration’s use of tariffs under the International Emergency Economic Powers Act, or IEEPA. However, in response to the U.S. Supreme Court ruling, the current presidential administration imposed a new worldwide tariff under other legal authority, effective for 150 days from February 24, 2026. While the baseline tariff has been temporarily reduced, the underlying trade tensions and the potential reimposition of elevated tariffs may continue to pose risks to global supply chains and economic relations. It is unknown whether and to what extent new tariffs, export controls, or other new laws or regulations will be adopted, or the effect that any such actions would have on us or our industry. Historically, tariffs have led to increased political tensions, between not only the United States and China, but also between the United States and other countries in the international community. Political tensions as a result of trade policies could reduce trade volume, investment, technological exchange, and other economic activities between major international economies, resulting in a material adverse effect on global economic conditions and the stability of global financial markets. Any changes in political, trade, regulatory, and economic conditions, including, but not limited to, U.S. and China trade policies, could have a material adverse effect on our financial condition or results of operations. In addition, increased tariffs on critical raw materials, components, and finished goods could raise our production costs and disrupt our supply chain, which could adversely affect our clinical development activities.

Previous wording

Many of our product candidates/programs are in preclinical or early-stage clinical development. We have not yet completed any pivotal clinical trials, obtained regulatory approvals, manufactured a commercial scale product (or arranged for a third party to do so on our behalf), or conducted sales and marketing activities necessary for successful commercialization of any of our product candidates. Aside from EIK1001, which is our most advanced product candidate currently being evaluated in a Phase 2/3 registrational trial in combination with pembrolizumab for the treatment of patients with advanced melanoma, as well as a Phase 2 trial and Phase 2/3 registrational trial (for which we recently initiated site selection) in combination with pembrolizumab and chemotherapy for the treatment of patients with NSCLC, all of our other development programs are either in early-stage clinical development, or will need to progress through IND-enabling studies and receive authorization from the FDA or a comparable foreign regulatory authority to proceed under an IND or other submission prior to initiating clinical development. We may not be able to file INDs or other submissions for any of our preclinical product candidates on the timelines we expect, or at all. Even if we submit an IND or other submission for a product candidate, the FDA or a comparable foreign regulatory authority may not clear the IND or other submission and allow us to begin clinical trials in a timely manner, or at all. The timing of submissions of INDs or other submissions for our product candidates will be dependent on further preclinical and manufacturing success. Commencing each of these clinical trials is subject to finalizing the trial design based on discussions with the FDA and comparable foreign regulatory authorities. Any guidance we receive from the FDA or comparable foreign regulatory authorities is subject to change. These regulatory authorities could change their position, including, on the acceptability of our trial designs or the clinical endpoints selected, which may require us to complete additional clinical trials or impose stricter approval conditions than we currently expect. Furthermore, the recent turnover at the FDA under the current presidential administration could lead to further delays and unpredictability in FDA’s clinical development and/or regulatory approval processes, which could adversely affect our ability to advance the development of our product candidates/programs.

Previous wording

All of our product candidates are either in preclinical or early clinical development, except for EIK1001, which is currently being evaluated in a Phase 2/3 registrational trial in combination with pembrolizumab for the treatment of patients with advanced melanoma, as well as a Phase 2/3 trial in which we recently initiated site selection, in combination with pembrolizumab and chemotherapy for the treatment of patients with NSCLC. The risk that our product candidates fail to proceed successfully through clinical development is high. We expect it could be many years before we commercialize any product candidate, if ever. The product candidates we are developing are novel and unproven, which makes it difficult to accurately predict the challenges we may face with respect to our product candidates as they proceed through development. It is also impossible to predict whether our clinical trials will proceed through registrational trials, and when or if any of our product candidates will receive regulatory approval. To obtain the requisite regulatory approvals to commercialize any product candidates, we must demonstrate through extensive preclinical studies and lengthy, complex, and expensive clinical trials that our product candidates are safe and effective in humans. Clinical testing can take many years to complete, and its outcome is inherently uncertain. Commencing any future clinical trials is subject to finalizing the trial design and submitting an IND and/or protocols to the FDA or a comparable foreign regulatory authority. Even after we make our submission, the FDA or comparable foreign regulatory authority could disagree that we have satisfied their requirements to commence our clinical trials or disagree with our trial design, which may require us to complete additional studies or trials, amend our protocols, or impose stricter conditions on the commencement of clinical trials. Furthermore, the recent turnover at the FDA under the current presidential administration could lead to further delays and unpredictability in FDA’s regulatory approval process, which could adversely affect our ability to advance the development of our product candidates.

Any of these regulatory authorities may also change the requirements for the approval of a product candidate even after reviewing and providing comments or advice on a protocol for a clinical trial. The FDA or comparable foreign regulatory authorities may require that we conduct additional clinical, preclinical, manufacturing validation, or drug product quality studies and submit those data before considering or reconsidering the application. Depending on the extent of these or any other studies, approval of any applications that we submit may be delayed by several years, or may require us to expend more resources than we have available. It is also possible that additional studies, if performed and completed, may not be considered sufficient by the FDA or comparable foreign regulatory authorities for granting approval.

Delays, including delays caused by the above factors and other factors described in this section of this Quarterly Report titled “Risk Factors,” can be costly and could negatively affect our ability to complete preclinical studies or clinical trials or obtain timely marketing approvals. We do not know whether any of our planned preclinical studies or clinical trials will begin on or be completed on a timely basis, or at all. For example, the FDA or comparable foreign regulatory authorities may place a partial or full clinical hold on any of our clinical trials for a variety of reasons, including safety concerns or failure to comply with regulatory requirements. If we are not able to complete successful clinical trials, we will not be able to obtain regulatory approval and will not be able to commercialize our product candidates.

Accordingly, assuming we, or any partners, obtain marketing approval for one or more of our product candidates, we, our partners, and our CMOs will continue to expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance, and quality control. If we are not able to comply with post-approval regulatory requirements, we could have the marketing approvals for our products withdrawn by regulatory authorities, and our ability to market any future products could be limited, which could adversely affect our ability to achieve or sustain profitability. As a result, the cost of compliance with post-approval regulations may have a negative effect on our operating results and financial condition.

EIK1001 was in-licensed from a Cayman Islands entity with significant operations in China. In addition, under the collaboration agreement, or the Impact Agreement, with Impact, a Chinese entity, we received an exclusive license under certain of Impact’s patents, know-how, and regulatory information to develop and commercialize any selective PARP1 inhibitors owned or controlled by Impact or its affiliates, including our product candidates EIK1003 and EIK1004, and any pharmaceutical products comprised of or containing such inhibitors, on a worldwide basis excluding China, Hong Kong, Taiwan, and Macau. Pursuant to the Impact Agreement, Impact conducts clinical trials for EIK1003 and EIK1004 in these regions. The U.S. government has recently made statements and taken certain actions that may lead to potential changes to U.S. and international trade policies, including imposing several rounds of tariffs and export control restrictions affecting certain products manufactured in China, and most recently, proposing legislation that, if enacted, would restrict trade with certain Chinese companies that provide biopharmaceutical research, development, and manufacturing services. Recently, both China and the United States have each imposed tariffs indicating the potential for further trade barriers, including the U.S. Commerce Department adding numerous Chinese entities to its “unverified list,” which requires U.S. exporters to go through more procedures before exporting goods to such entities. On February 20, 2026, the U.S. Supreme Court ruled against the current presidential administration’s use of tariffs under the IEEPA.

We are conducting several clinical trials, and intend to conduct other future clinical trials, in a number of countries around the world. The acceptance of data from clinical trials conducted outside the United States or another jurisdiction by the FDA or comparable foreign regulatory authorities may be subject to certain conditions or may not be accepted at all, including as a basis for later-stage clinical trials. In cases where data from foreign clinical trials is intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (among other prerequisites) (i) the data are applicable to the U.S. population and U.S. medical practice, (ii) the trials were performed by clinical investigators of recognized competence in accordance with applicable GCPs, and (iii) the data may be considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical power, must be met. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, we would need to conduct additional trials, which could be costly and time-consuming.

Even if we obtain regulatory approval for any of our product candidates, there is no assurance that either we or our CMOs will be able to manufacture the approved product in accordance with requirements from the FDA or comparable foreign regulatory authorities to produce it in sufficient quantities to meet the requirements for the potential launch of the product or to meet potential future demand. Our manufacturing activities are subject to ongoing, unannounced inspections by the FDA and comparable regulatory authorities. Any of these challenges could delay completion of clinical trials, require bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, result in sanctions being imposed on us (including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, suspension of production or recalls of the product candidates, operating restrictions, and criminal prosecutions), delay approval of our product candidates, impair commercialization efforts, or increase our cost of goods, any of which would have an adverse effect on our business, financial condition, results of operations, and prospects. Our future success depends on our ability to manufacture our products on a timely basis with acceptable manufacturing costs, while at the same time maintaining good quality and complying with applicable regulatory requirements. An inability to do so could have a material adverse effect on our business, financial condition, results of operations, and prospects. In addition, we could incur higher manufacturing costs if manufacturing processes or standards change, and we could need to replace, modify, design, build, or install equipment, all of which would require additional capital expenditures.

We are exploring and may in the future continue to explore the use of certain of our product candidates in combination with other therapies. For example, we are evaluating in a Phase 2/3 registrational trial the effect of EIK1001 in combination with pembrolizumab for the treatment of patients with advanced melanoma, and in a Phase 2 trial, as well as a Phase 2/3 registrational trial for which we recently initiated site selection, of EIK1001 in combination with pembrolizumab and chemotherapy for the treatment of patients with NSCLC. As such, we are subject to the risk that the FDA or comparable foreign regulatory authorities could revoke approval of, or that safety, efficacy, manufacturing, or supply issues could arise with, the therapy used in combination with our product candidate. If the therapies we use in combination with our product candidates are replaced as the standard of care, the FDA or comparable foreign regulatory authorities may require us to conduct additional clinical trials, or we may not be able to obtain adequate reimbursement from payors. The occurrence of any of these risks could result in our product candidates, if approved, being removed from the market or being less successful commercially. If we are unable to use pembrolizumab in our current combination trials for EIK1001, we may be required to enroll additional patients at existing sites or identify new trial sites. As a result, our clinical development activities could be delayed or otherwise adversely affected, which could adversely affect our business, financial condition, results of operations, and prospects.

Our success depends in large part on our ability to seek, obtain, and maintain patent and other intellectual property protection in the United States and other countries for our product candidates and their uses, as well as our ability to operate without infringing, misappropriating, or otherwise violating the intellectual property and proprietary rights of others. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to our novel discoveries and technologies that are important to our business, and in-licensing similar rights. Our ability to stop unauthorized third parties from making, using, selling, offering to sell, or importing our product candidates is dependent upon the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities. The risks associated with patent rights generally apply to patent rights that we in-license now or in the future, as well as patent rights that we may own now or in the future. While we in-licensed certain issued patents related to EIK1001 from Seven and Eight, none of the patent applications we own or in-license in connection with EIK1003, EIK1004, EIK1005, or EIK1006 have issued yet, and there is no assurance that any such patent applications will issue at all or in a manner that provides us with any competitive advantage. In addition, the chemical structure of EIK1001 is in the public domain. Accordingly, we are unable to obtain any composition of matter patents claiming the composition of matter of EIK1001 as a sole active ingredient. We in-licensed patent applications relating to methods of using EIK1001 to treat certain indications, crystal forms of EIK1001, and a Patent Cooperation Treaty, or PCT, application relating to dosing of EIK1001, however, there is no assurance that these applications will issue or, even if they are issued, will be sufficient to prevent others from developing products that compete with EIK1001. Moreover, we or our licensors have also filed PCT and provisional patent applications related to EIK1001, EIK1003, EIK1004, EIK1005, and EIK1006, and none of our owned or in-licensed provisional or PCT patent applications are eligible to become an issued patent until, among other things, we or our licensors, as applicable, file a non-provisional patent application within 12 months of the filing date of the applicable provisional patent application, or file national stage applications based on the applicable PCT applications. Any failure to file a non-provisional patent application or a national stage application based on a PCT application could cause us to lose the ability to obtain patent protection for the inventions disclosed in the associated provisional patent application or PCT application. Moreover, we cannot assure you that our owned and in-licensed pending patent applications will issue, or that any future issued patents will afford sufficient protection of our product cand…

Composition of matter patents for biological and pharmaceutical product candidates often provide a strong form of intellectual property protection for those types of products, as such patents provide protection without regard to any specific method-of-use. In particular, composition of matter patent claims covering the active pharmaceutical ingredient, or API, in pharmaceutical drug products are generally considered to be the favored form of intellectual property protection for drug products, because such patents provide protection without regard to any particular method of use or manufacture or formulation or dosing of the API used. However, we only have issued patents directed to the composition of matter of EIK1001 in combination with one or more other substances. Further, we cannot be certain that the claims in our pending or future owned or in-licensed patent applications directed to the composition of matter of our other product candidates will be considered patentable by the United States Patent and Trademark Office, or the USPTO, or by patent offices in foreign countries, or that the claims in any of our current or future owned or in-licensed issued patents will be considered valid and enforceable by courts in the United States or foreign countries. Method-of-use patent claims protect the use of a product in the methods claimed in the patents, and dosing patent claims cover dosing regimens of the API or a formulation thereof. These types of patent claims do not prevent a competitor or other third party from making and marketing a product, including an API, that is identical to our product candidates for an indication that is outside the scope of the method-of-use claims, or from developing an identical product with a different dosing regimen that is outside the scope of the dosing claim. Moreover, with respect to method-of-use patents, even if competitors or other third parties do not actively promote their product for our targeted indications or uses for which we may obtain patents, clinicians may prescribe these products “off-label,” or patients may acquire them and use them in such manner themselves. Although off-label use may infringe or contribute to the infringement of method-of-use patents, the practice is common and such infringement is difficult to prevent or prosecute.

The issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability and our pending patent applications, and those of any collaborators or licensors, may be challenged in the courts, the USPTO or patent offices abroad. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. For example, our pending patent applications may be subject to third-party submissions of prior art to the USPTO. Such submissions may also be made prior to a patent’s issuance, precluding the granting of a patent based on one or more of our owned or licensed pending patent applications. In addition, our issued patents may be subject to post-grant review, or PGR, proceedings, oppositions, derivations, reexaminations, interferences, inter partes review, or IPR, proceedings or other similar proceedings, in the United States or elsewhere, challenging our patent rights or the patent rights of others. An adverse determination in any such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated, or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and product candidates, or limit the duration of the patent protection of our technology and product candidates. Such challenges also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us. Any of the foregoing could adversely affect our business, financial condition, results of operations, and prospects. For example, our European patent EP 3166976 B2, which is directed to pharmaceutical combinations relating to EIK1001, was opposed before the European Patent Office. The opposition, which was filed in November 2022, has concluded without the need for an oral hearing. The Opposition Division issued its Interlocutory Decision in October 2025 maintaining our patent in amended form.

For example, we are currently engaged in a payment-related dispute with Seven and Eight. Seven and Eight has alleged that it did not receive a payment we made to Seven and Eight as required by our collaboration agreement and thus such payment is still owed. Although we believe our payment was made in good faith, if we are unable to reach a mutually agreeable resolution to this matter with Seven and Eight, arbitration may be necessary. If this dispute or other disputes involving our license and collaboration agreements, including disputes over intellectual property or other proprietary rights that we license now or in the future, prevent or impair our ability to maintain our licensing arrangements on commercially reasonable terms, we may not be able to successfully develop and commercialize the affected product candidates, if approved, which would have a material adverse effect on our business. If our licenses are terminated, we may lose our rights to develop and market our technology and product candidates, lose patent protection for our product candidates and technology, experience significant delays in the development and commercialization of our product candidates, if approved, or incur liability for damages.

The regulations that govern marketing approvals, pricing, and reimbursement for new drug products and biologics vary widely from country to country. Current and future legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals. Some countries require approval of the sale price of a product before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay or limit our commercial launch of the product, possibly for lengthy time periods, which could negatively impact the revenue we generate from the sale of the product in that particular country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, the ability to hire and retain key personnel, the ability to accept the payment of user fees, and statutory, regulatory, and policy changes.

In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

Social media is increasingly being used to communicate about clinical development programs and the diseases our product candidates are being developed to treat. We may utilize appropriate social media in connection with communicating about our development programs. Social media practices in the biopharmaceutical industry continue to evolve and regulations relating to such use are not always clear. This evolution creates uncertainty and risk of noncompliance with regulations applicable to our business. For example, patients may use social media channels to report an alleged adverse event during a clinical trial. When such disclosures occur, we may fail to monitor and comply with applicable adverse event reporting obligations, or we may not be able to defend our business or the public’s legitimate interests in the face of the political and market pressures generated by social media due to restrictions on what we may say about our product candidates. There is also a risk of inappropriate disclosure of sensitive information or negative or inaccurate posts or comments about us on any social networking website, or a risk that a post on a social networking website by any of our employees may be construed as inappropriate promotion. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur liability, face regulatory actions, or incur other harm to our business.

Numerous U.S. states have enacted comprehensive privacy laws that impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and affording residents with certain rights concerning their personal data. As applicable, such rights may include the right to access, correct, or delete certain personal data, and to opt-out of certain data processing activities, such as targeted advertising, profiling, and automated decision-making. The exercise of these rights may affect our business. Certain states also impose stricter requirements for processing certain personal data, including sensitive data, such as conducting data privacy impact assessments. Failure to comply with these laws, where applicable, can result in significant statutory fines. For example, the California Consumer Privacy Act, as amended by the California Privacy Rights Act of 2020, collectively the CCPA, applies to personal data of consumers, business representatives, and employees who are California residents, and requires businesses to provide specific disclosures in privacy notices, and honor requests of such individuals to exercise certain privacy rights, including allowing customers to opt out of certain data sharing with third parties. The CCPA provides for fines of up to $7,500 per intentional violation and allows private litigants to recover significant statutory damages for certain data breaches, thereby potentially increasing risks associated with a data breach. The CCPA and other comprehensive U.S. state privacy laws exempt some data processed in the context of clinical trials, but these developments may further complicate compliance efforts, and increase legal risk and compliance costs for us and the third parties with whom we work. Several other states have passed comprehensive privacy laws similar to the CCPA. Like the CCPA, these laws create obligations related to the processing of personal information, as well as special obligations for the processing of “sensitive” data. Some of the provisions of these laws may apply to our business activities. A number of similar privacy laws are also being considered in several other states as well as at the federal level, which may add additional complexity, variation in requirements, restrictions, and potential legal risk, and require additional investment of resources in compliance programs, alter data handling strategies, and restrict the availability of previously useful data, and could result in increased compliance costs or changes in business practices and policies. The existence of comprehensive privacy laws in different states in the country would make our compliance obligations more complex and costly, and may increase the likelihood that we may be subject to enforcement actions or otherwise incur liability for noncompliance.

The holders of 29,855,741 shares of our outstanding common stock, or approximately 55% of our total outstanding common stock as of March 31, 2026, are entitled to rights with respect to the registration of their shares under the Securities Act, subject to the lock-up agreements described above. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act.

Previous wording

As of May 1, 2026, our executive officers, directors, and holders of 5% or more of our capital stock beneficially owned approximately 52% of our voting stock. As a result, these stockholders, if acting together, will continue to have influence over the outcome of corporate actions requiring stockholder approval, including the election of directors, amendment of our organizational documents, any merger, consolidation, or sale of all or substantially all of our assets, and any other significant corporate transaction. The interests of these stockholders may not be the same as or may even conflict with your interests. For example, these stockholders could delay or prevent our change of control, even if such a change of control would benefit our other stockholders, which could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of us or of our assets and might affect the prevailing market price of our common stock. The significant concentration of stock ownership may adversely affect the trading price of our common stock due to investors’ perception that conflicts of interest may exist or arise.

Previous wording

The tax regimes we are subject to or operate under, including with respect to income and non-income taxes, are unsettled and may be subject to significant change. Changes in tax laws, regulations, or rulings, or changes in interpretations of existing laws and regulations, could materially adversely affect us. For example, the IRA includes provisions that impose a 15% minimum tax, or CAMT, on the adjusted financial statement income of certain large corporations. CAMT is effective for taxable years beginning after December 31, 2022 and generally applies to taxpayers with average annual financial statement income exceeding $1 billion over a three-year period. The impact of this law was not material to us for the three months ended March 31, 2026, though it is possible that CAMT may have a material impact on our financial position in future years. Likewise, on July 4, 2025, the One Big Beautiful Bill Act, or the Act, was enacted into law. The Act includes significant changes to the U.S. tax code, including restoration of immediate recognition of domestic research and development expenditures and reinstatement of 100% bonus depreciation for qualifying property. We do not currently anticipate the Act to have a material impact on our financial position.

We are also a “smaller reporting company” as defined in the Exchange Act. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our common stock held by non-affiliates is less than $250.0 million measured on the last business day of our most recently completed second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value our common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter. Even after we no longer qualify as an emerging growth company, we could still qualify as a smaller reporting company, which would allow us to take advantage of many of the same exemptions from disclosure requirements and reduced disclosure obligations regarding executive compensation in our Annual Report on Form 10-K and our other periodic reports and proxy statements. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our share price may be more volatile.
