Previous wording

We have incurred significant annual net operating losses in every year since our inception. We have no products approved for commercial sale and have not generated any revenue from product sales to date, and we continue to incur significant research and development and other general and administrative expenses related to our ongoing operations. If tegoprubart or any future product candidates we develop are not successfully developed and approved, we may never generate any revenue from sales of products. The Company has experienced recurring net losses and negative cash flows from operating activities since its inception. The Company’s net loss for the six months ended June 30, 2025 is $17.7 million. As of June 30, 2025, the Company had cash and cash equivalents and short-term investments of $107.6 million, working capital of $97.7 million and an accumulated deficit of $373.3 million. We have not generated any revenues from product sales, have not completed the development of any product candidate and may never have a product candidate approved for commercialization. We expect it will be several years, if ever, before we have a product candidate ready for commercialization. We have financed our operations to date primarily through the sale of preferred and common stock, and the sale of warrants and have devoted substantially all of our financial resources and efforts to research and development, including preclinical studies and our clinical trials. Our net losses may fluctuate significantly from quarter to quarter and year to year and will depend, in part, on the rate at which we incur expenses and our ability to generate revenue. Net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.

Previous wording

In addition to the dilution of our current stockholders’ ownership as a result of the 2023 Private Placement, the 2024 Private Placement and the 2024 Underwritten Offering, we currently have a significant number of securities outstanding that are exercisable for our common stock, which could result in significant additional dilution and downward pressure on our stock price. Future issuances of our common stock, including common stock that may be issuable pursuant to outstanding warrants or other convertible securities, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

Previous wording

As of June 30, 2025, there were 59,881,775 shares of our common stock outstanding and warrants to purchase 33,052,744 shares of our common stock outstanding. The issuance of shares of common stock in the 2023 Private Placement, the 2024 Private Placement and the 2024 Underwritten Offering (each as defined and described in Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations), diluted the ownership interests of our existing stockholders. The issuance of shares of common stock pursuant to our “at-the-market” equity offering program or upon exercise of pre-funded warrants or common warrants issued in the initial closing of the 2023 Private Placement, the pre-funded warrants issued in the 2024 Private Placement and the pre-funded warrants issued in the 2024 Underwritten Offering would result in significant additional dilution to our current stockholders, which could adversely affect the price of our common stock and the terms on which we could raise additional capital. If we sell additional shares of common stock, convertible securities or other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our existing stockholders, and new investors could gain rights, preferences and privileges senior to the holders of our common stock.

Current wording

As of September 30, 2025, there were 59,881,775 shares of our common stock outstanding and pre-funded warrants and common stock warrants to purchase 32,425,811 shares of our common stock outstanding. In conjunction with the 2025 Underwritten Offering, we issued an additional 19,698,085 shares of common stock and also issued pre-funded warrants to purchase 15,151,515 shares of our common stock. The issuance of shares of common stock in the 2023 Private Placement, the 2024 Private Placement, the 2024 Underwritten Offering and the 2025 Underwritten Offering (each as defined and described in Part I, Item 2.

Previous wording

We currently do not have any products that have gained regulatory approval. We have invested substantially all of our efforts and financial resources in the development of our lead drug candidate tegoprubart, including funding non-clinical studies, clinical trials, drug formulation and the manufacturing of clinical trial materials. Our ability to generate product revenues, which we do not expect will occur for several years, if ever, will depend heavily on the successful development and eventual commercialization of one or more drug candidates. As a result, our business is substantially depending on our ability to successfully complete the development of and obtain approval for one of our potential future additional product candidates.

Previous wording

there may be changes in governmental regulations or administrative actions. For example, the Trump administration recently issued an Executive Order that pauses the FDA’s rulemaking ability and could affect recently finalized FDA rules that have not yet taken effect. The extent to which such existing or future executive orders impact the healthcare regulatory environment remains uncertain and could materially impact our development and commercialization activities. In addition, our development and commercialization activities could be harmed or delayed by a shutdown of the U.S. government or reduction in funding or staffing at U.S. government agencies, including the FDA. For example, a prolonged shutdown or the reduction of funding or staffing at the FDA may significantly delay the FDA's ability to timely review and process any submissions we may file or cause other regulatory delays, which could materially and adversely affect our business.

Further, government shutdowns and/or employee terminations or resignations at the SEC could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Previous wording

In order to market and sell our products in the EU and other international jurisdictions outside of the United States, we or our third-party collaborators must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and may require additional non-clinical, clinical or health outcome data. In addition, the time required to obtain approval may differ substantially amongst international jurisdictions.

In addition, the time required to obtain approval may differ substantially amongst international jurisdictions. The regulatory approval process outside the United States generally includes all the risks associated with obtaining FDA approval. In addition to regulatory approval, in many countries outside the United States, it is required that the product be approved for reimbursement before the product can be approved for sale in that country.

Previous wording

Healthcare providers, physicians and third-party payers will play a primary role in the recommendation and prescription of any product candidates for which we receive marketing approval. Our current and future arrangements may expose us to broadly applicable fraud and abuse and other healthcare laws that may constrain the business or financial arrangements and relationships through which we would market, sell and distribute the products for which we receive marketing approval. Even though we will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payers, federal and state healthcare laws are and will be applicable to our business. Such laws include, but are not limited to federal false claims, false statements and civil monetary penalties laws, including the federal civil False Claims Act (“FCA”), the federal Anti-Kickback Statute, the federal Health Insurance Portability and Accountability Act of

Previous wording

Laws, restrictions, and other regulatory measures are also imposed by anti-kickback, fraud and abuse, and other healthcare laws and regulations in international jurisdictions, and in those jurisdictions we face the same issues as in the United State regarding exposure to criminal sanctions, civil penalties, program exclusion, contractual damages, reputational harm, and diminished profits and future earnings.

Previous wording

We rely on our information systems and infrastructure to effectively manage our business, including our clinical trials and studies. Our information systems and infrastructure, and those of our current or future third-party collaborators, service providers, contractors and consultants are vulnerable to damage from cybersecurity incidents, including computer viruses, denial-of-service attacks, hacking, phishing and other social engineering attacks, unauthorized access or use resulting from malware, as well as disruptions due to natural disasters, terrorism, war, mistakes or technical errors, including due to software updates and telecommunication and electrical failures. We may also experience cybersecurity incidents stemming from persons inside our organizations (including employees or contractors), or other persons with access to information systems inside our organization. Attacks on information systems are increasing in their frequency, levels of persistence, sophistication and intensity, and they are being conducted by increasingly sophisticated and organized foreign governments, groups and individuals with a wide range of motives and expertise. Further, cybersecurity threats and the techniques used in cyberattacks change, develop and evolve rapidly, including from emerging technologies, such as advanced forms of artificial intelligence and quantum computing. In addition to extracting or accessing sensitive information, such attacks could include the deployment of harmful malware, ransomware, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the security, confidentiality, integrity and availability of information. The prevalent use of mobile devices that access sensitive information also increases the risk of data security incidents which could lead to the loss of confidential information or other intellectual property. Information system disruptions, even if inadvertent, may limit or disable our access or important third parties’ access to our systems. While to our knowledge none of the cybersecurity incidents we have experienced to date have had a material adverse impact on our business, financial condition or operations, if such an event were to occur and cause interruptions in our operations or the operations of third-party collaborators, service providers, contractors or consultants, it could result in a material disruption of our development programs and significant reputational, financial, legal, regulatory, business or operational harm. The costs to us to mitigate, investigate and respond to potential security incidents, breaches, disruptions, network security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant, and while we have implemented security measures to protect our data security and information systems, our efforts to address these problems may not be successful, and these problems could result in unexpected interr…

Previous wording

We expect to rely on third-party manufacturers or third-party collaborators for the manufacture of commercial supply of any other product candidates for which our collaborators or we obtain marketing approval. Despite drug substance and product risk management, this reliance on third parties presents a risk that we will not have sufficient quantities of our product candidates or products or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts. For example, these third parties experienced disruptions in their operations in conjunction with the COVID-19 pandemic. Additionally, on April 16, 2025, the U.S. Department of Commerce (the “Commerce Department”) announced an investigation under Section 232 of the Trade Expansion Act of 1962 into imports of pharmaceuticals and pharmaceutical ingredients, including finished drug products, medical countermeasures, critical inputs such as active pharmaceutical ingredients, and key starting materials, and derivative products of those items. The investigation will examine the impact of these imports on U.S. national security culminating in a decision by the President whether to take action to remedy any identified threats, including by imposing additional tariffs. Any delay or performance failure on the part of our existing or future manufacturers of drug substance or drug products could delay clinical development or marketing approval. We do not currently have arrangements in place for redundant supply. If suppliers cannot supply us with our requirements, we may be required to identify alternative manufacturers, which would lead us to incur added costs and delays in identifying and qualifying any such replacement.

Further, the U.S. government has proposed a 100% tariff on branded and patented pharmaceutical products. All of these current and threatened tariffs are subject to implementation or change with little notice. Any delay, performance failure, or increase in costs on the part of our existing or future manufacturers of drug substance or drug products could delay or increase the cost of our clinical development or marketing approval. We do not currently have arrangements in place for redundant supply.
