Risk Factors This section provides an extensive overview of the risks facing the company, including financial losses, dependence on candidates, and IP risks Risks Related to Our Business and Industry This subsection outlines fundamental business risks, emphasizing the company's history of significant net losses and the need for future funding - The company has incurred significant losses since inception, with an accumulated deficit of $1,064.9 million as of March 31, 2025, and expects to incur losses for the foreseeable future154 - The company will require substantial additional funding to complete the development of its antibody candidates. While existing cash is expected to fund operations into 2028, this estimate is based on assumptions that may prove wrong159160 - The business heavily depends on the success of its antibody candidates, which require significant further development, regulatory approval, and commercialization efforts163 Risks Related to the Development and Clinical Testing of Our Antibody Candidates This subsection details the inherent risks of drug development, including lengthy, expensive, and uncertain clinical trials with potential for adverse side effects - Clinical drug development is a lengthy, expensive process with uncertain outcomes, and failure can occur at any time. Early positive results are not predictive of later-stage success184 - Antibody candidates may cause serious or undesirable side effects, which could delay or prevent marketing approval. Adverse reactions have been observed in trials for zenocutuzumab, petosemtamab, and MCLA-129198199200 - BIZENGRI® received accelerated approval, which is contingent upon verification of clinical benefit in confirmatory trials. Failure to do so, or to comply with post-marketing requirements, could lead the FDA to withdraw the approval228230 Risks Related to Commercialization of Our Antibody Candidates This subsection addresses the challenges of bringing products to market, including intense competition and the need for market acceptance and reimbursement - The biopharmaceutical industry is highly competitive, and competitors may develop safer, more effective, or less expensive products more rapidly279280 - Successful commercialization depends on adequate coverage and reimbursement from government and private payors, which is uncertain and subject to increasing pricing pressures289 - The company has limited marketing, sales, and distribution infrastructure and relies on its licensee, PTx, for the U.S. commercialization of BIZENGRI®. It may not be successful in building these capabilities for other candidates298300 Risks Related to Our Dependence on Third Parties The company's business model is heavily reliant on third parties for clinical trials, manufacturing, and strategic collaborations - The company relies on third-party CROs to conduct clinical trials and CMOs to manufacture antibody candidates. Failure by these parties to perform their duties or meet regulatory standards could delay or halt development307333 - Key collaborations with Incyte, Lilly, Gilead, Biohaven, and PTx are critical. The company is dependent on these partners for development and commercialization activities, and termination or underperformance by a partner would adversely affect the business313319323 Risks Related to Intellectual Property and Information Technology This subsection highlights significant IP and IT risks, including challenges to patents, infringement claims, and vulnerability to cyberattacks - The company's success depends on protecting its intellectual property, but patents may be challenged, narrowed, or invalidated. For example, Xencor has filed IPR petitions challenging two of the company's U.S. patents339341342 - The company may be required to litigate to defend its patents or against claims that it infringes third-party IP, which is costly and time-consuming. The company has filed a patent infringement lawsuit against Xencor348358 - Information technology systems are vulnerable to security breaches and cyberattacks, which could lead to the loss of trade secrets, disruption of clinical trials, and significant financial and reputational harm385386 Risks Related to Employee Matters and Managing Growth The company's future success is dependent on its ability to retain key senior management and scientific personnel and to recruit additional qualified staff - Success depends on retaining key personnel. The loss of senior leaders could delay R&D activities. Competition for qualified personnel is intense388 - Recent senior management changes, including the departures of the CBO, CMO, and CDO, and the appointments of a new CMO and CPO, require orderly transitions to avoid business disruption389 Risks Related to Our Common Shares This subsection details risks for investors in the company's common shares, including price volatility, anti-takeover provisions, and tax consequences - The company's share price is highly volatile and subject to fluctuation from factors like clinical trial results, regulatory decisions, and market conditions407 - Anti-takeover provisions under Dutch law and in the company's articles of association may deter acquisition bids or prevent changes in the board of directors392394 - The company may be classified as a Passive Foreign Investment Company (PFIC) for U.S. federal income tax purposes, which could result in adverse tax consequences for U.S. investors402 - As a Dutch company, it may be difficult for U.S. shareholders to enforce judgments from U.S. courts against the company in the Netherlands400 Item 5.
