Added paragraphs (13)
Current report
We are currently conducting, and may in the future conduct, clinical trials for current or future product candidates outside the U.S., and the FDA and comparable foreign regulatory authorities may not accept data from such trials.
Current report
The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect. For example, we may incorrectly determine that our product candidates are not covered by a third-party patent or may incorrectly predict whether a third-party’s pending application will issue with claims of relevant scope. Our determination of the expiration date of any patent in the U.S. or abroad that we consider relevant may be incorrect. Our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market our product candidates.
Current report
Changes in patent law in the U.S. and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.
Current report
We also are subject to or may in the future become subject to numerous foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. The foreign regulatory approval process varies among countries and may include all of the risks associated with the FDA approval process described above, as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Moreover, the time required to obtain approval may differ from that required to obtain FDA approval. FDA approval does not ensure approval by regulatory authorities outside the U.S. and vice versa. Any delay or failure to obtain U.S. or foreign regulatory approval for a product candidate could have a material and adverse effect on our business, financial condition, results of operations and prospects.
Current report
We face uncertainty regarding the potential for changes in the regulatory environment following the change in presidential administration in January 2025. While many of the Trump administration’s proposed policies appear to be focused on deregulation, the new administration and federal government could adopt legislation, regulation, or policy that adversely affects our business or creates a more challenging and costly environment to pursue the development and commercialization of our product candidates. For example, the federal government, including the FDA, may implement legislative, regulatory, or policy changes regarding the standards for approving biologic products that we may be unable to satisfy. It is difficult to predict how executive actions that may be taken under the current Trump administration may affect the FDA’s ability to exercise its regulatory authority. If such executive actions impose constraints on the FDA’s
Current report
ability to engage in routine oversight and product review activities in the normal course, our business may be negatively impacted.
Current report
Disruptions at the FDA and other regulatory authorities may also slow the time necessary for new biologics or modifications to approved or licensed biologics to be reviewed and/or approved, which would adversely affect our business. For example, the current Trump administration appears to be focused on decreasing spending in the federal government, including through significant staff reductions. Any significant staff reductions at FDA could impact the agency’s ability to engage in routine regulatory and oversight activities and result in delays or limitations on our ability to proceed with clinical development programs and obtain regulatory approvals. Additionally, reductions in the workforce, particularly in the review or inspection divisions, could extend BLA review timelines, delay or prevent pre-approval inspections, and limit opportunities for FDA feedback on pending applications. Over the last several years, the U.S. government has shut down several times and certain regulatory authorities, such as the FDA, have had to furlough critical employees and stop critical activities.
Current report
Governments outside the U.S. tend to impose strict price controls, which may adversely affect our revenue, if any.
Current report
Significant political, trade, regulatory developments, including changes in relations between the U.S. and China, and other circumstances beyond our control, may adversely impact our business, financial condition, and results of operations.
Current report
Various political, trade, or regulatory developments have, and could further, adversely affect our business and the results of our operations and financial condition. For example, recent actions and statements by the governments of the U.S. and China, including those relating to the imposition or threatened imposition of tariffs, or potential increases to tariffs, affecting certain products manufactured in China, have impacted, and may continue to impact, companies like us who rely on suppliers and other commercial partners with significant operations in China. For example, while we have selected new CMOs in the U.S. to establish additional sources of supply, currently we import from China certain drug substance, drug product and other components, and such imports are subject to existing tariffs and may be impacted by additional tariffs. Currently, many of our suppliers primarily operate outside of the U.S., including our current sole CMO, WuXi Biologics, which provides its services to us from facilities located in China, and increases in tariffs could result in increased costs. As a result, we are subject to risks associated with political, trade, regulatory developments with respect to such countries, and between the U.S. and such countries. Any unfavorable legislation, regulations, executive orders, government policies on cross-border relations and/or international trade, including increased scrutiny on certain of our suppliers with significant China-based operations, capital controls, or tariffs, may have an adverse effect on our business, financial condition, and results of operations. For example, in March and April 2025, the U.S. imposed tariffs on, or increased the tariff rates applicable to, imports from many foreign countries. In response to these tariffs, a number of other countries have threatened or implemented retaliatory tariffs on U.S. goods. Political tensions resulting from 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. Further, supply chain disruptions and delays as a result of tariff policies or trade restrictions could also negatively impact our cost of materials and processes. Such changes in political, trade, regulatory, and economic conditions, including U.S. trade policies, could have a material adverse effect on our financial condition or results of operations.
Current report
Insiders have substantial influence over us, which could limit other stockholders’ ability to affect the outcome of key transactions, including a change of control.
Current report
Securities class action litigation imposes costs on our business.
Current report
Securities class action litigation often is instituted against issuers following periods of volatility or declines in the market prices of an issuer’s securities. As an example, in April 2025, a putative securities class action was filed against us and certain of our directors and officers, as well as the underwriters in our IPO. The action, purportedly brought on behalf of a putative class of purchasers of our common stock in, or traceable to, our IPO, asserts claims under Sections 11, 12, and 15 of the Securities Act of 1933, as amended. The action seeks compensatory damages, attorneys’ fees and costs, and any other relief that the court determines is just and proper. Often multiple plaintiffs’ attorneys file similar complaints and, at a future point, a consolidated amended complaint is filed. We do not anticipate providing updates for similar complaints or developments in this litigation, absent a legal obligation. Securities litigation results in costs and diversion of management’s time and attention. The underwriting agreement from our IPO contemplates that we cover certain litigation expenses incurred by the underwriters in connection with the suit referenced above. Costs we incur addressing securities litigation harm our business, operating results, and financial condition, potentially with significant impact. Securities litigation also often raises the cost of directors’ and officers’ liability insurance. We factor those costs into the policy limits and scope of coverage we obtain, with those costs a key factor in determining the extent to which we rely on our balance sheet, rather than insurance, to cover defense costs, any settlement amounts, or any damages awarded to plaintiffs in litigation.

Recent and future changes to tax laws could adversely affect our company.
Previous report
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 adversely affect our company. For example, the Tax Cuts and Jobs Act, the Coronavirus Aid, Relief, and Economic Security Act, and the Inflation Reduction Act of 2022 (the “IRA”) enacted many significant changes to the U.S. tax laws. Future guidance from the Internal Revenue Service and other tax authorities with respect to such legislation may affect us, andcertain aspects thereof could be repealed or modified in future legislation. For example, the IRA includes provisions that will impact the U.S. federal income taxation of certain corporations, including imposing a 15% minimum tax on the book income of certain large corporations and a 1% excise tax on certain corporate stock repurchases that would be imposed on the corporation repurchasing such stock.
Previous report
Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts
Previous report
or investors perceive these results to be negative, it could adversely affect the price of shares of our common stock. Moreover, we may not have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a result of the proceedings.

Previous report
The U.S. Supreme Court’s June 2024 decision inLoper Bright Enterprises v. Raimondooverturned the longstandingChevrondoctrine, under which courts were required to give deference to regulatory agencies’ reasonable interpretations of ambiguous federal statutes. TheLoperdecision could result in additional legal challenges to regulations and guidance issued by federal agencies, including FDA and the Center for Medicare & Medicaid Services, on which we rely. Any such legal challenges, if successful, could have a material impact on our business. Additionally, theLoperdecision may result in increased regulatory uncertainty, inconsistent judicial interpretations, and other impacts to the agency rulemaking process, any of which could adversely impact our business and operations. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action or as a result of legal challenges, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, our business could be materially harmed.
Previous report
In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to “opt out” of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we will adopt the new or revised standard at the time private companies adopt the new or revised standard and will do so until such time that we either (i) irrevocably elect to “opt out” of such extended transition period, or

(ii)no longer qualify as an emerging growth company. Therefore, the reported results of operations contained in our financial statements may not be directly comparable to those of other public companies.
Previous report
The trading market for our common stock will be influenced in part by the research and reports that industry or securities analysts publish about us or our business. We do not have any control over the industry or securities analysts, or the content and opinions included in their reports and may never obtain research coverage by securities and industry analysts. If no or few securities or industry analysts continue to cover us, or if analysts cease coverage of us, we could lose visibility in the financial markets, and the trading price forour common stock could be impacted negatively. If any of the analysts who cover us publish inaccurate or unfavorable research or opinions regarding us, our business model, our intellectual property or our stock performance, or if our preclinical studies and clinical trials and operating results fail to meet the expectations of analysts, our stock price would likely decline.

Our insurance policies are expensive and only protect us from some business risks, which will leave us exposed tosignificant uninsured liabilities.
Previous report
In the past, securities class action litigation has often been instituted against companies following periods of volatility in the trading price of a company’s securities. This type of litigation, if instituted, could result in substantial costs and a diversion of management’s attention and resources, which would harm our business, operating results or financial condition. Additionally, the dramatic increase in the cost of directors’ andofficers’ liability insurance may cause us to opt for lower overall policy limits or to forgo insurance that we mayotherwise rely on to cover significant defense costs, settlements and damages awarded to plaintiffs.

Adequate additional financing may not be available to us on acceptable terms, or at all, including as a result of financial and credit market deterioration or instability, market-wide liquidity shortages, geopolitical events or otherwise. If we are unable to raise sufficient additional capital, we would be forced to curtail our planned operations and the pursuit of our growth strategy.

Previous wording
A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unfavorable safety profiles, notwithstanding promising results in earlier trials. For example, we are developing obexelimab as a potential treatment for IgG4-RD, MS, SLE and wAIHA. Prior to our acquisition of obexelimab, Xencor conducted a Phase 2 trial of obexelimab in patients with SLE, where the primary endpoint was not achieved with statistical significance. The results of our clinical trials of obexelimab in SLE or other indications or our clinical trials for any other product candidates may not achieve statistical significance or demonstrate a favorable risk-benefit profile. Further, negative clinical trial results for a product candidate with respect to one indication may impact the potential or perceived potential of other indications. Moreover, clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of such product candidates.

Commencing any future clinical trials is subject to finalizing the trial design and submitting an application, such as an IND, to the FDA or a comparable foreign regulatory authority. Even after the submission of an IND, the FDA or comparable foreign regulatory authorities could disagree that their requirements to commence a clinical trial have been satisfied or disagree with the study design, which may require the completion of additional trials or the amendment of the trial’s protocols or the imposition of stricter conditions on the commencement of the clinical trial. We may be unable to establish clinical endpoints, dose levels and regimens or bioanalytical assay methods that regulatory authorities would consider clinically meaningful. A high failure rate characterizes product candidates proceeding through clinical trials, and failure may occur at all stages of the clinical trial process. Most product candidates that commence clinical trials are never approved as products, and our current or future clinical trials ultimately may fail to support the approval of our current or any future product candidates.

In addition, our clinical trials currently, and may in the future, compete with other clinical trials forproduct candidates that address the same disease as our product candidates, and this competition reduces the number and types of participants available to us, because some participants who might have opted to enroll in our trials instead opt to enroll in a trial conducted by a competitor or elect to use a marketed therapy. We also could encounter delays if doctors face ethical challenges associated with enrolling participants in a clinical trial rather than prescribing an existing treatment with an established safety and efficacy profile.

While we believe that obexelimab has the potential to offer benefits, including in regard to its side-effect profile, over B cell depleting agents, if obexelimab is shown to have adverse events, side effects or other safetyor tolerability concerns, then our opportunity to disrupt the current standard of care will be limited. AEs and SAEs may be deemed to be related to our product candidates. Such a determination may require longer and more extensive clinical development, or regulatory authorities may increase the amount of data and information required to approve, market or maintain approval of our product candidates.

Our current product candidates, initially under development for treatment of various I&I indications would, if approved, face competition from existing approved immunological treatments, many of which have achieved commercial success. For example, we are currently developing obexelimab for the treatment of IgG4-RD, MS, SLE and wAIHA. There are currently no approved therapies for IgG4-RD or wAIHA, but there are two products approved for SLE, and a number of products approved for MS. Moreover, there are a number of product candidates in clinical development by other companies for IgG4-RD, MS, SLE and wAIHA which may become available in the future, including UPLIZNA (inebilizumab-cdon), an anti-CD19 antibody being developed by Amgen Inc., for which Amgen has announced its intention to file a BLA based on the results of its Phase 3 clinical trial in patients with IgG4-RD.

Because we have limited financial and managerial resources, we focus our development efforts on certain selected product candidates in certain selected indications. For example, we are initially focused on our lead product candidate, obexelimab, for the treatment of IgG4-RD, MS, SLE and wAIHA. As a result, we may forgo or delay pursuit of opportunities with other product candidates or other indications for our existing product candidates that later prove to have greater commercial potential. Additionally, negative clinical trial results with respect to one indication of a product candidate may impact the potential or perception of other indications of the product candidate. Our resource allocation decisions may result in our failure to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future development programs and product candidates for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application unless the data are applicable to the United States population and United States medical practice, the trials were performed by clinical investigators of recognized competence and pursuant to GCP regulations and 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 powering, must be met. Many comparable foreign regulatory authorities have similar approval requirements. In addition, foreign trials are subject to local laws of the foreign jurisdictions where the trials are conducted. The FDA or any comparable foreign regulatory authority may not accept data from trials conducted outside of the United States or the applicable jurisdiction, which would result in the need for additional trials that could be costly and time consuming and could result in the product candidate not receiving approval for commercialization in the applicable jurisdiction.

The availability of coverage and the adequacy of reimbursement by governmental healthcare authorities or programs such as Medicare and Medicaid, private health insurers and other third-party payors are essential for most patients to be able to afford prescription medications such as our product candidates, if approved.

No uniform policy for coverage and reimbursement for products exists among third-party payors in the United States. Coverage and reimbursement for products can therefore differ significantly from payor to payor. Even if we obtain coverage for a given product by a third-party payor, the reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. Coverage and adequate reimbursement in the United States or elsewhere may not be available for any product that we may develop, and any coverage or reimbursement that may be obtained could be reduced or eliminated in the future.

Third-party payors increasingly are challenging prices charged for biopharmaceutical products and services. Even if we show improved efficacy, safety or convenience of administration with obexelimab or any of our other product candidates, pricing of competitive products may limit the amount we will be able to charge for any of our product candidates, if approved. Third-party payors may deny or revoke the reimbursement status of a product or establish payment for new or existing marketed products at levels that are too low to enable us to realize an appropriate return on our investment in our product candidates. When new competitor generic and biosimilar products enter the market, pricing or reimbursement for the innovator compound may be reduced. More generally, the existence of generic and biosimilar products or other therapeutic alternatives within a “therapeutic category” may result in reduced reimbursement from payors. Additionally, new competitor brand drugs can trigger therapeutic category reviews in the interest of modifying coverage and/or reimbursement levels. We may be required to provide discounts or rebates under government healthcare programs or to certain government and private purchasers in order to obtain coverage under federal healthcare programs such as Medicaid. More generally, we may need to offer price concessions to third party payors to obtain favorable coverage or to purchasers to achieve sales. Such actions could have a negative impact on our ability to successfully commercialize any of our product candidates, if approved. Additionally, if a companion diagnostic test is developed for use with a drug product, any coverage and reimbursement for that test would be separate and apart from the coverage and reimbursement sought for such drug product. A lack of coverage or adequate reimbursement for such a test could adversely affect access to a drug product.

Outside the U.S., international operations are generally subject to extensive governmental price controls and other market regulations, and we believe the increasing emphasis on cost-containment initiatives in Europe and other countries has and will continue to put pressure on the pricing and usage of products like our product candidates. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to fix their own prices for medical products but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates, if approved. Accordingly, in markets outside the U.S., the reimbursement for our product candidates may be lower than in the U.S. and may be insufficient to generate meaningful revenue and profits. Factors outside the U.S. that may be relevant in pricing and reimbursement determinations by health authorities, including in European countries, may include, without limitation, perceived cost-effectiveness perceived benefit to patient quality of life, and designation as an orphan drug indication, among others.

Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates, if approved. Accordingly, in markets outside the United States, the reimbursement for our product candidates may be lower than in the United States and may be insufficient to generate meaningful revenue and profits.

Although we exclusively in-license patent portfolios from Xencor related to obexelimab, ZB002 and ZB004, we have no solely owned issued patents.

or increased costs due to new government regulations, for example, from future legislation or administrative action, or from changes in FDA policy during the period of product development, clinical trials and FDA regulatory review. It is impossible to predict whether additional legislative changes will be enacted, or whether FDA or foreign regulations, guidance or interpretations will be changed, or the impact of such changes, if any. Any elongation or de-prioritization of preclinical studies or clinical trials or delay in regulatory review resulting from such disruptions could materially affect the development and study of obexelimab or any of our other product candidates or any future product candidates.

a data breach. Although the law includes limited exceptions, including for certain information collected as part of clinical trials, the CCPA may impact our processing of personal information and increases our compliance costs. Additionally, the California Privacy Rights Act of 2020 (“CPRA”) significantly expands the CCPA, such as granting additional rights to California residents, including the right to correct personal information and additional opt-out rights. The CPRA also establishes a regulatory agency dedicated to enforcing the CCPA and the CPRA. At least 11 other states have also passed comprehensive privacy laws, and similar laws are being considered in several other states, as well as at the federal and local levels. While these state privacy laws, like the CCPA, also exempt some data processed in the context of clinical trials, these developments further complicate compliance efforts, and increase legal risk and compliance costs for us and the third parties upon whom we rely. In addition to government activity, privacy advocacy groups and technology and other industries are considering various new, additional or different self- regulatory standards that may place additional burdens on us.

Moreover, these rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.
