Current report
We have initiated SOLARA, a pivotal, open-label, single-arm, multicenter Phase 3 clinical trial evaluating sutacimig at a dose of 0.2 mg/kg once weekly as a prophylactic therapy in patients aged 12 to 70 with Glanzmann thrombasthenia, at sites in the United States and other countries. The FDA has recommended that we consider a randomized controlled design. However, the FDA acknowledged our concerns about the feasibility of randomization in Glanzmann thrombasthenia. In light of the substantial variability in treated bleeding rates, the heterogeneity of the patient population, and the practical challenges of randomized trials in a rare disease, we have determined to proceed with a single-arm trial. Under this design, each participant’s on-demand treatment data collected during a pre-treatment observation period serves as the comparator for that participant’s outcomes while receiving sutacimig. As a result, it may be more difficult to determine whether observed differences are attributable to sutacimig rather than differences in bleeding events, treatment practices, reporting, participant characteristics or other factors between the observation and treatment periods. In addition, the open-label nature of SOLARA may introduce bias in the identification, reporting, classification or assessment of bleeding events and treatment responses.
Current report
The FDA and other regulatory authorities have substantial discretion in determining whether evidence from a single-arm trial is adequate to establish safety and effectiveness. Even if SOLARA meets its prespecified endpoints, regulatory authorities may determine that the trial design, comparator data, number or characteristics of enrolled participants, duration of follow-up, handling of missing or variable data, statistical analyses, or magnitude or consistency of the observed treatment effect do not provide substantial evidence supporting approval of sutacimig. Regulatory authorities also may interpret the results differently from us or require additional analyses, longer follow-up or one or more additional clinical trials, including a randomized controlled trial. Any such determination could delay or prevent approval of sutacimig for Glanzmann thrombasthenia, increase our development costs and materially harm our business.
Current report
For heavy menstrual bleeding, the competitive landscape includes currently available hormonal and non-hormonal therapies, as well as surgical procedures. Tranexamic acid, an oral antifibrinolytic marketed as Lysteda and available in generic form, is the primary non-hormonal therapy for heavy menstrual bleeding, although its short half-life requires frequent dosing during menstruation. Hormonal therapies approved for heavy menstrual bleeding include an oral contraceptive (Natazia), a levonorgestrel-releasing intrauterine system (Mirena) and, for heavy menstrual bleeding associated with uterine fibroids, oral GnRH receptor antagonist combination therapies (Oriahnn and Myfembree). Non-steroidal anti-inflammatory drugs are also commonly used. Patients who do not respond to, or are not candidates for, medical therapy may undergo surgical procedures such as endometrial ablation or hysterectomy. These therapies and procedures are well established and widely used, and generic tranexamic acid and many hormonal contraceptives are available at low cost. This may make it difficult for HMB-003, if approved, to achieve market acceptance or obtain adequate coverage and reimbursement. In addition, other companies may develop longer-acting antifibrinolytics or other non-hormonal therapies for heavy menstrual bleeding.
Current report
We are committed to remediating the material weaknesses described above. During 2026, with the assistance of a third-party consulting firm, we completed a risk assessment and walkthroughs of our business processes over financial reporting, advanced documentation of the related processes and controls, and designed new and enhanced controls over our financial statement close and reporting process and information technology general controls, including controls over user access and change management. We commenced implementation of these controls during the three months ended September 30, 2026 and expect to commence testing of their operating effectiveness during the fourth quarter of 2026. The material weaknesses will not be considered remediated until the applicable controls have operated for a sufficient period of time and management has concluded, through testing, that these controls are designed and operating effectively, and we cannot predict when remediation will be completed.

Previous report
Although we are planning to conduct a multinational, multicenter, Phase 3, open-label clinical trial evaluating sutacimig as a prophylactic therapy in adults with Glanzmann thrombasthenia, the FDA may determine that a randomized controlled clinical trial is necessary to support filing and approval of our Biologics License Application, or BLA. We intend to schedule a Type D meeting with the FDA in the coming months to obtain the FDA’s feedback on, and seek alignment regarding, our proposed Phase 3 trial design. A Type D meeting is intended to facilitate focused discussion on a limited number of specific issues, but there can be no assurance that the FDA will agree with our proposed approach. If the FDA requires us to conduct a randomized controlled Phase 3 clinical trial, we could incur additional costs and delays, to the extent any such trial is more complex, time-consuming and/or expensive to design, initiate and complete. A randomized trial may require a larger number of patients, longer enrollment and follow-up periods, and additional clinical sites, which could delay the timing of any regulatory submission and potential approval. In addition, the use of a control arm may introduce ethical, operational and recruitment challenges, particularly if patients or investigators are reluctant to participate in a study where treatment assignment is randomized. There is also a risk that a randomized trial could fail to meet its primary or secondary endpoints, even if a single-arm study might have demonstrated favorable results, which could materially and adversely affect our ability to obtain regulatory review and approval and commercialize our product candidate.
Previous report
The FDA may also designate a product for Fast Track review if it is intended, whether alone or in combination with one or more other products, for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for such a disease or condition. For Fast Track products, sponsors may have greater interactions with the FDA, and the FDA may initiate review of sections of a Fast Track product’s application before the application is complete. This rolling review may be available if the FDA determines, after preliminary evaluation of clinical data submitted by the sponsor, that a Fast Track product may be effective.
Previous report
In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions and could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

To remediate these material weaknesses, we have made and plan to continue to make improvements to the design and operating effectiveness of our internal controls over financial reporting, including the monitoring, oversight and evaluation of our internal controls. We also plan to allocate more internal resources to our internal controls, including by hiring additional staff, and intend to engage external advisors to provide training and to reassess and redesign processes and develop new controls as appropriate, including information technology controls covering access and change management as well as cyber risks, and assisting with the evaluation and documentation of the risk assessment, design and operating effectiveness of our internal controls over financial reporting.

Previous wording
We are a clinical-stage biopharmaceutical company with a limited operating history. Since our inception, we have devoted substantially all of our financial resources and efforts to research and development, including clinical trials and preclinical studies of our product candidates, sutacimig and HMB-002, along with several preclinical programs focusing on coagulation disorders, such as HMB-003, and have incurred significant operating losses. Our net losses were $46.8 million for the six months ended June 30, 2026 and $63.9 million for the year ended December 31, 2025. As of June 30, 2026, we had an accumulated deficit of $228.7 million. We have no approved products, and we have not generated any revenue from product sales. We have financed our operations primarily through private placements of convertible preference shares, issuances of convertible debt and, most recently, from the sale of common stock in our initial public offering, or IPO, in May 2026. We are still continuing to research and develop our product candidates, and we have not yet completed the development of any of our product candidates. We expect to continue to incur significant operating expenses and net losses for the foreseeable future. Our operating expenses and net losses may fluctuate significantly from quarter to quarter and year to year. Accordingly, our stockholders should not rely upon the results of any particular quarterly or annual period as indications of future operating performance. Because of the numerous risks and uncertainties associated with developing pharmaceutical products, we are unable to predict the extent of any future losses or when we will become profitable, if at all. Even if we become profitable, we may not be able to sustain or increase our profitability on a quarterly or annual basis.

Our operations have consumed substantial amounts of cash since inception. Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory approvals and achieve product sales. We expect to devote substantial financial resources to our ongoing and planned activities, particularly as we commence our planned Phase 3 clinical trial of sutacimig in patients with Glanzmann thrombasthenia and continue our ongoing Phase 1/2 clinical trial of sutacimig in patients with Glanzmann thrombasthenia, Phase 2 clinical trial of sutacimig in patients with Factor VII deficiency and Phase 1/2 trial of HMB-002 in patients with Von Willebrand Disease, and progress HMB-003 into first-in-human studies in patients with heavy menstrual bleeding, continue research and development and initiate additional clinical trials of, and seek marketing approval for, these and other product candidates. We expect our expenses to increase substantially in connection with our ongoing and planned activities, particularly as we advance our preclinical activities and clinical trials of and potentially seek marketing approval for our product candidates and other product candidates we may identify, and if and as we expand our research and development and scale-up and manufacture our product candidates for our current and future indications. We will be required to incur substantial costs and may experience delays in completing, or ultimately be unable to complete, the development and commercialization of any product candidates.

As of June 30, 2026, we had cash, cash equivalents and marketable securities of $457.5 million. We believe that our cash, cash equivalents and marketable securities as of June 30, 2026 will enable us to fund our operating expenses and capital expenditure requirements into 2029. However, we have based this estimate on assumptions that may prove to be wrong, and our operating plan may change as a result of many factors currently unknown to us. As a result, we could deplete our capital resources sooner than we currently expect and could be forced to seek additional funding sooner than planned. We would be required to obtain substantial additional funding in order to initiate and conduct registrational and other clinical trials for our product candidates.

We commenced operations in 2020 and are a clinical-stage biotechnology company. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, securing intellectual property rights, in-licensing technology, discovering product candidates, undertaking preclinical studies and conducting clinical trials. While we are in the process of conducting Phase 1/2 and Phase 2 trials, we have not yet initiated or completed a Phase 3 clinical trial of any product candidate. We have not yet demonstrated our ability to successfully develop any product candidate, obtain marketing approvals, manufacture a commercial-scale product or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Therefore, we cannot be certain that our ongoing preclinical studies and clinical trials will be completed on time or that our planned preclinical studies and clinical trials will begin or be completed on time, if at all. Further, biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. Our stockholders should consider our prospects in light of the costs, uncertainties, delays, and difficulties frequently encountered by companies in clinical development, especially clinical-stage biopharmaceutical companies such as ours. Any predictions our stockholders make about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing products.

Moreover, our ability to use our NOLs and other deferred tax assets to offset future taxable income in Denmark and the United States may be limited if we experience an ownership change. For Danish income tax purposes, an ownership change will generally occur when one, or several shareholders together, at once or successively, acquire shares representing more than 50% of the share capital or voting power. Although such an ownership change entails no reduction of the amount of NOLs to be carried forward, the utilization is restricted to exclude offsetting against positive net capital income (e.g. income from interest, dividend and royalty) on NOLs incurred in a previous income year, where the ownership has changed by more than by 50% (under section 12D of the Danish Corporate Tax Act). In the United States, in general, under Section 382 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, a corporation that undergoes an “ownership change,” generally defined as a greater than 50 percentage point change (by value) in its equity ownership by certain stockholders over a three-year period, is subject to limitations on its ability to utilize its pre-change NOLs and research and development tax credit carryforwards to offset future taxable income. We have not conducted a study to assess whether any such ownership changes have occurred. We may have experienced such ownership changes in the past and may experience such ownership changes in the future through subsequent changes in our stock ownership (which may be outside our control). As a result, if, and to the extent that, we earn net taxable income, our ability to use our pre-change NOLs and research and development tax credit carryforwards to offset such taxable income may be subject to limitations.

We currently have no products that are approved for commercial sale and may never be able to develop marketable products. We expect that a substantial portion of our efforts and expenditures over the next several years will be devoted to sutacimig and HMB-002, which are currently our only clinical-stage product candidates, and HMB-003, which is in preclinical development. Accordingly, our business currently depends heavily on the successful development, marketing approval and commercialization of these product candidates. We cannot be certain that sutacimig, HMB-002 or HMB-003 will receive marketing approval, be approved for the indications that we may seek or be successfully commercialized even if we receive marketing approvals. If we were required to discontinue development of sutacimig, HMB-002 or HMB-003 or if any of these product candidates do not receive marketing approvals or fail to achieve significant market acceptance, we would be delayed by many years in our ability to achieve profitability, if ever, and may not be able to generate sufficient revenue to continue our business.

The risk of failure for our product candidates and any other product candidates we may develop is high. It is impossible to predict when or if our product candidates and any other product candidates we may develop will prove effective or safe in humans or will receive marketing approval. The time required to obtain approval from the FDA, EMA or other comparable foreign regulatory authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of regulatory authorities. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of such product candidate in humans. We have not yet initiated a pivotal clinical trial for any of our product candidates. Clinical trials may fail to demonstrate that our current or future product candidates are safe for humans and effective for indicated uses. Even if initial clinical trials in any of our product candidates we may develop are successful, these product candidates may fail to show the desired safety and efficacy in later stages of clinical development despite having successfully advanced through preclinical studies and initial clinical trials. There is a high failure rate for drugs proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in later-stage clinical trials even after achieving promising results in earlier-stage clinical trials.

The outcome of preclinical testing and earlier-stage clinical trials may not be predictive of the success of later-stage clinical trials. Our product candidates and any other product candidates we may develop may fail to show the desired safety, potency and purity in clinical development despite positive results in preclinical studies or having successfully advanced through initial clinical trials. For example, we are currently planning our Phase 3 clinical trial of sutacimig in patients with Glanzmann thrombasthenia, based on the positive results of our Phase 1/2 dose-finding study in patients with Glanzmann thrombasthenia. However, we cannot provide assurances that the evidence of activity we observed in our Phase 1/2 trial of sutacimig will translate to our planned Phase 3 clinical trial. Additionally, any positive results generated in our ongoing and planned clinical trials do not ensure that we will achieve similar results in later-stage clinical trials of these product candidates, and we cannot provide assurances that we will be able to seek or obtain marketing approval for any of our product candidates even if our clinical trials are successful.

From time to time, we may publish or report interim, top-line or preliminary results from our clinical trials. For example, we plan to report data for our Phase 2 clinical trial of sutacimig in Factor VII deficiency in late 2026 or early 2027, and data from our Phase 1/2 clinical trial of HMB-002 in patients with Von Willebrand Disease in late 2026 or early 2027. Interim results from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary, interim or top-line results also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary or interim data we previously published. As a result, interim, top-line and preliminary data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could be material and could significantly harm our reputation and business prospects and may cause the trading price of our common stock to fluctuate significantly.

For example, we plan to report data from our Phase 2b clinical trial of sutacimig in Factor VII deficiency in December 2026, and data from our Phase 1/2 clinical trial of HMB-002 in patients with Von Willebrand Disease in February 2027. Interim results from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary, interim or top-line results also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary or interim data we previously published. As a result, interim, top-line and preliminary data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could be material and could significantly harm our reputation and business prospects and may cause the trading price of our common stock to fluctuate significantly.

We will need to successfully complete pivotal clinical trials in order to obtain the approval of the FDA, the EMA, or other regulatory agencies to market our product candidates or any future product candidate. Carrying out later-stage clinical trials is a complicated process. As an organization, we have not previously conducted any pivotal clinical trials. In order to do so, we will need to significantly expand our clinical development and regulatory capabilities. In addition, we may be unable to recruit and train qualified personnel. Consequently, we may be unable to successfully and efficiently execute and complete necessary clinical trials in a way that leads to approval of our product candidates or future product candidates. We may require more time and incur greater costs than our competitors and may not succeed in obtaining marketing approvals of product candidates that we develop.

Identifying and qualifying patients to participate in clinical trials for our product candidates and any other product candidates we may develop is critical to our success. Successful and timely completion of clinical trials will require that we enroll a sufficient number of patients, as required by the FDA, EMA or similar regulatory authorities in other jurisdictions, who remain in the trial until its conclusion. Additionally, the prevalence of patients with Glanzmann thrombasthenia, Factor VII deficiency and Von Willebrand Disease is estimated to be low, and we estimate that there are approximately an aggregate of 10,000 patients with Glanzmann thrombasthenia and Factor VII deficiency and an aggregate of 120,000 patients with Von Willebrand Disease in the geographies where we intend to commercialize, including the United States, the European Union, Japan, the GCC countries and other select regions. We may not be able to identify, recruit, and enroll a sufficient number of patients to complete our clinical trials of our product candidates because of the perceived risks and benefits of our product candidates, the availability of competing therapies and clinical trials, the proximity and availability of clinical trial sites for prospective subjects and the subject referral practices of physicians, among other factors. Patient enrollment is affected by a variety of other factors, including:

In addition, as we continue to evaluate our product candidates, rare and severe side effects of our product candidates may be uncovered in the later stages of our current and future clinical development. For example, in our Phase 1/2 clinical trial of sutacimig in Glanzmann thrombasthenia, several patients have experienced events of thrombosis. In particular, one patient experienced a grade 2 proximal deep vein thrombotic event at the highest exposure level (0.9 mg/kg) and one patient at the 0.3 mg/kg dose level (whose dose had been reduced from 0.6 mg/kg) experienced grade 2 subsegmental pulmonary embolism. These events were reported to the FDA on an expedited reporting basis as an event of a type referred to as a Suspected Unexpected Serious Adverse Reaction (SUSAR). While we have selected a lower dose of 0.2 mg/kg for purposes of our planned Phase 3 clinical trial, thrombotic events have been reported at the 0.3 mg/kg dose level, and there is no guarantee that thrombotic events or other serious adverse events will not occur even at lower doses. In addition, sutacimig’s mechanism of action inherently carries the risk of thrombotic complications if the drug achieves excessive systemic exposure or if patients have concurrent prothrombotic conditions or other risk factors.

Additionally, if results of our clinical trials reveal unacceptable side effects, we, the FDA or the IRBs at the institutions in which our studies are conducted could suspend or terminate our clinical trials, or the FDA or comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates and any other product candidates we may develop for any or all targeted indications. Furthermore, we expect that our clinical trial protocol for our planned Phase 3 trial may require us to pause or stop enrollment in the trial if one or more thrombotic events occur in order to assess whether it is safe to proceed with further enrollment and dosing. Any such event could cause significant delays in the execution and completion of the trial, or lead to discontinuation altogether. Treatment-related side effects could also affect patient recruitment or the ability of enrolled patients to complete any of our clinical trials. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We may need to train medical personnel using our product candidates to understand the side effect profiles for our clinical trials and upon any commercialization of any of our product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in harm to patients that are administered our product candidates. Any of these occurrences may adversely affect our business, financial condition and prospects significantly.

We may conduct one or more of our clinical trials with one or more trial sites that are located outside the United States or European Union. The acceptance of data from clinical trials conducted outside the United States or another jurisdiction by the FDA may be subject to certain conditions or may not be accepted at all. Similarly, the EMA, and other equivalent foreign regulatory authorities may not accept data from trials conducted outside their jurisdiction. For example, we are currently conducting our ongoing Phase 2 clinical trial of sutacimig in patients with Factor VII deficiency at sites in the United Kingdom, and our ongoing Phase 1/2 trial of HMB-002 in patients with Von Willebrand Disease at sites in United Kingdom, Australia, and the United States. We plan to conduct our Phase 3 clinical trial of sutacimig in patients with Glanzmann thrombasthenia in the United States, Europe and potentially other jurisdictions. In cases where data from clinical trials outside of the United States are intended to serve as the basis for marketing approval in the United States, acceptance of these data is subject to conditions imposed by the FDA. For example, the clinical trial must be well designed and conducted and be performed by qualified investigators in accordance with ethical principles. The FDA must be able to validate the data from the trial through an onsite inspection, if necessary. The trial population must also adequately represent the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. In addition, while these clinical trials are subject to the applicable local laws, whether the FDA accepts the data will depend on its determination that the trials also complied with all applicable U.S. laws and regulations. Additionally, recent policy proposals in the United States, if enacted in the future, may make acceptance by the FDA or inclusion in a marketing application of non-U.S. data more difficult or costly. There can be no assurance that the FDA will accept data from trials conducted outside of the United States. If the FDA does not accept the data from any trial that we conduct outside the United States, it would likely result in the need for additional trials, which would be costly and time-consuming and could delay or permanently halt our development of the applicable product candidates.

The FDA reviews an application to determine whether there is “substantial evidence” to support a finding of effectiveness for the proposed product for its intended use(s). The FDA has interpreted this evidentiary standard to generally require two adequate and well-controlled clinical trials to establish effectiveness of a new product. Under certain circumstances, however, the FDA has indicated that a single trial with certain characteristics and additional information may satisfy this standard. The FDA issued draft guidance in September 2023 that outlines considerations for relying on confirmatory evidence in lieu of a second clinical trial to demonstrate efficacy. The FDA has not yet finalized such guidance but, in February 2026, then existing FDA leadership published an editorial in the New England Journal of Medicine in which they declared that, in most cases, the new default requirement for FDA approval of a new product will be one robust pivotal clinical trial plus confirmatory evidence, rather than two pivotal clinical trials. In determining whether to rely on one trial, the FDA will focus on the single trial’s quality, including magnitude of effect, appropriateness of control arms, endpoint selection, statistical power, blinding, handling of missing data, biological plausibility and alignment with intermediate biomarkers. While the FDA has long had authority to approve new products in this manner and, in recent years, has exercised that authority with respect to certain types of products, the publication declares that this will be the new official default standard for most new products. This approach will reportedly be implemented as the FDA places a greater emphasis on collecting robust post-marketing data on all pharmaceutical products. At this point, it is unclear how this new policy will be implemented by the FDA and how, if at all, it will affect our clinical development programs. Moreover, although we are planning to conduct a multicenter, Phase 3, single-arm, open-label clinical trial evaluating sutacimig as a prophylactic therapy in adults with Glanzmann thrombasthenia, the FDA may determine that a randomized controlled clinical trial is necessary to support filing and approval of our BLA. We intend to schedule a Type D meeting with the FDA in the coming months to obtain the FDA’s feedback on, and seek alignment regarding, our proposed Phase 3 trial design. A Type D meeting is intended to facilitate focused discussion on a limited number of specific issues, but there can be no assurance that the FDA will agree with our proposed approach. Our failure to timely agree with the FDA on the design of our planned Phase 3 clinical trial may lead to delays in its initiation and completion.

In addition, the EU pharmaceutical legislation is currently undergoing a complete review process, in the context of the Pharmaceutical Strategy for Europe initiative, launched by the European Commission in November 2020. The European Commission’s proposal for revision of several legislative instruments related to medicinal products, which may reduce the duration of regulatory data protection and exclusivity periods for orphan drugs, and revise the eligibility for expedited pathways in addition to other changes, was published on April 26, 2023. On June 4, 2025, after almost two years of negotiations among the European Union member states, the Council of the European Union adopted its position on the proposed overhaul of the EU general pharmaceutical legislative framework, which is known as the new Pharma Package. On December 11, 2025, the European Parliament and European Council reached a provisional political agreement on the legislation. The revisions may have a significant impact on the pharmaceutical industry and our business. The new Pharma Package would, among other things, set a baseline period of eight years of data exclusivity and one year of market exclusivity with possible extensions for new indications up to a maximum of 11 years total. The new framework is expected to be adopted by the fall of 2026 and there will likely be a transition period of 24 months, with the changes taking effect in mid-2028.

Moreover, given the risk that could be the case, these provisions of the IRA may also further heighten the risk that we would not be able to achieve the expected return on any of our product candidates, if approved, or the full value of our patents protecting any such approved drug products if prices are set after any such approved products have been on the market for nine years.

On December 23, 2025, CMS, through its Center for Medicare and Medicaid Innovation, proposed two five-year pilot programs to implement a “reference pricing” regime for drugs paid for under Medicare for 25% of covered beneficiaries. The programs are referred to as the Global Benchmark for Efficient Drug Pricing Model for Medicare Part B drugs, referred to as GLOBE, and the Guarding U.S. Medicare Against Rising Drug Costs for Medicare Part D drugs, referred to as GUARD. Under the proposed pilot programs, a manufacturer would owe rebates to Medicare if prices for their drugs exceeded the prices paid by other economically comparable reference countries, defined in the proposed regulations as Organisation for Economic Co-operation and Development countries with a gross domestic product of $400 billion and a per capita gross domestic product that is at least 60% of the U.S. per capita gross domestic product (an initial list of 19 reference countries is included in the proposed rule). The pilot programs are proposed to go into effect beginning October 1, 2026.

Separately, on December 23, 2025, CMS, through its Center for Medicare and Medicaid Innovation, or CMMI, proposed two five-year pilot programs to implement a “reference pricing” regime for drugs paid for under Medicare for 25% of covered beneficiaries. The programs are referred to as the Global Benchmark for Efficient Drug Pricing Model for Medicare Part B drugs, referred to as GLOBE, and the Guarding U.S. Medicare Against Rising Drug Costs for Medicare Part D drugs, referred to as GUARD. Under the proposed pilot programs, a manufacturer would owe rebates to Medicare if prices for their drugs exceeded the prices paid by other economically comparable reference countries, defined in the proposed regulations as Organisation for Economic Co-operation and Development countries with a gross domestic product of $400 billion and a per capita gross domestic product that is at least 60% of the U.S. per capita gross domestic product (an initial list of 19 reference countries is included in the proposed rule). On September 30, 2026, CMS issued a final rule for the GLOBE Model. On October 7, 2026, PhRMA filed a lawsuit in the U.S. District Court for the District of Columbia challenging CMS’ final GLOBE Model and seeking declaratory and injunctive relief. The complaint asserts that CMS exceeded its authority under Section 1115A of the Social Security Act by CMMI’s demonstration authority to impose a mandatory manufacturer rebate regime tied to international reference prices. Although we cannot predict whether, when, or to what extent any of our product candidates, if approved, would become subject to these or future pricing and reimbursement programs, such measures could reduce reimbursement for pharmaceutical products, place downward pressure on pricing, increase rebate, discount, or other payment obligations, limit commercial flexibility, and adversely affect demand for pharmaceutical products.

Subsequently, in December 2025, as part of the Fiscal Year 2026 National Defense Authorization Act, President Trump signed into law the BIOSECURE Act. Under the BIOSECURE Act, U.S. government agencies cannot (1) buy or obtain biotechnology equipment or services provided by biotechnology companies of concern, or BCCs, (2) enter into, extend, or renew a contract with any entity using biotechnology equipment or services provided by a BCC to perform a government contract, or (3) expend, loan or grant funds for biotechnology equipment or services provided by a BCC, whether directly or through a loan or grant recipient. The BIOSECURE Act does not name specific companies as BCCs but treats any company on the Department of Defense 1260H list of “Chinese military companies” as a BCC. On December 18, 2025, the Chairs of multiple Senate and House committees, including the House Select Committee on China, sent a letter to the Department of Defense recommending that WuXi be added to the 1260H list, which would make it a BCC. The 1260H list was updated by the Department of Defense in January 2024 and January 2025. On June 8, 2026, the US Department of Defense released an updated version of its list of “Chinese Military Companies” operating in the United States, pursuant to the requirements of Section 1260H of the National Defense Authorization Act for Fiscal Year 2021. Notably, the Department added WuXi AppTec to the list, along with two other biotechnology companies (Complete Genomics and Novogene). Since WuXi AppTec was just added to the list, it will be covered under a five-year grandfather clause that allows any contracts signed before the effective date of the ban to be protected through 2031. Nonetheless, on June 11, 2026, WuXi AppTec filed a legal challenge to its designation as a Chinese Military Company. The implications of this action remain unclear.

Sales of a substantial number of shares of our common stock in the public market, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. As of June 30, 2026, we had 46,705,410 shares of common stock outstanding, which includes the 19,262,500 shares that we sold in our IPO, which may be resold in the public market immediately without restriction, unless purchased by our affiliates.

We cannot assure our stockholders that the measures we have taken to date, and actions we plan to take in the future, will be sufficient to remediate the control deficiencies that led to the material weaknesses in our internal control over financial reporting or that they will prevent or avoid potential future material weaknesses. In addition, neither our management nor an independent registered public accounting firm has performed an evaluation of our internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act because no such evaluation has been required. Had we or our independent registered public accounting firm performed an evaluation of our internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act, additional material weaknesses may have been identified. If we are unable to successfully remediate our existing or any future material weaknesses in our internal control over financial reporting, or identify any additional material weaknesses in the future, or otherwise fail to maintain an effective system of internal controls, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting, and the market price of our common stock may decline as a result.

The trading market for our common stock relies, in part, on the research and reports that industry or financial analysts publish about us or our business. We do not currently have, and may never obtain, research coverage by industry or financial analysts. If no, or few, analysts commence coverage of us, the trading price of our stock would likely decrease. Even if we do obtain if one or more of the analysts covering our business downgrade their evaluations of our stock or publish inaccurate or unfavorable research about our business, or provides more favorable relative recommendations about our competitors, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could lose visibility in the market for our stock, which in turn could cause our stock price and trading volume to decline.

(SUSAR). While we have selected a lower dose of 0.2 mg/kg for purposes of our SOLARA Phase 3 clinical trial, thrombotic events have been reported at the 0.3 mg/kg dose level, and there is no guarantee that thrombotic events or other serious adverse events will not occur even at lower doses. Although we selected the 0.2 mg/kg once-weekly Phase 3 dose and regimen to avoid the high peak exposures associated with the thromboembolic events observed in our Phase 1/2 clinical trial, the Phase 3 dose may not reduce the incidence of thromboembolic or other adverse events to the extent we expect, or at all. In addition, sutacimig’s mechanism of action inherently carries the risk of thrombotic complications if the drug achieves excessive systemic exposure or if patients have concurrent prothrombotic conditions or other risk factors. HMB-002’s intended mechanism of increasing von Willebrand factor, or VWF, and Factor VIII levels could also increase thrombotic risk, particularly in patients with concurrent conditions that increase VWF levels, such as pregnancy, acute illness, or hormonal contraception use, or result in other adverse events.

On June 8, 2026, the U.S. Department of Defense released an updated version of its list of “Chinese Military Companies” operating in the United States, pursuant to the requirements of Section 1260H of the National Defense Authorization Act for Fiscal Year 2021. Notably, the Department added WuXi AppTec to the list, along with two other biotechnology companies (Complete Genomics and Novogene). Since WuXi AppTec was recently added to the list, it will be covered under a five-year grandfather clause that allows any contracts signed before the effective date of the ban to be protected through 2031. Nonetheless, on June 11, 2026, WuXi AppTec filed a legal challenge to its designation as a Chinese Military Company. The implications of this action remain unclear. On August 7, 2026, the U.S. District Court for the District of Columbia granted a preliminary injunction prohibiting enforcement of the designation, finding that the company had demonstrated a likelihood of success on its claim that the designation was arbitrary and capricious. The litigation remains ongoing, and while the injunction provides interim relief from the designation, there can be no assurance regarding the ultimate outcome of the case or the potential impact of future governmental actions relating to national security, procurement, supply chain, or biotechnology-related restrictions.
