The risks most specific to ADC Therapeutics

  • Risks Related to Our Financial Position, Capital Requirements and Ability to Raise Additional Capital

    Our indebtedness under the Loan Agreement and the associated restrictive covenants thereunder could adversely affect our financial condition

    Indebtedness under our Loan Agreement requires significant cash for debt service, reducing funds available for operations and research.

  • Risks Related to Our Financial Position, Capital Requirements and Ability to Raise Additional Capital

    The HCR Agreement reduces the amount of cash we are able to generate from sales of, and licensing agreements involving, ZYNLONTA and could make us a less attractive acquisition target

    The HCR Agreement obligates us to pay royalties and milestone percentages on ZYNLONTA sales and licenses, reducing net cash generation.

  • Risks Related to Our Financial Position, Capital Requirements and Ability to Raise Additional Capital

    Our consolidated statements of operations are subject to considerable non-cash charges and volatility due to factors that may be beyond our control

    Deerfield Warrants are recorded as liabilities and remeasured at fair value, causing non-cash charges and volatility based on our share price.

  • Risks Related to Our Financial Position, Capital Requirements and Ability to Raise Additional Capital

    Our ability to use tax loss carryforwards may be limited

    We reported $1,059 million in Swiss tax loss carryforwards as of December 31, 2024, which expire after seven years and have limited use.

  • Risks Related to Research and Development

    We may not be successful in our efforts to expand the market opportunity of ZYNLONTA, develop additional product candidates or build up our research pipeline

    We may fail to expand the market opportunity for ZYNLONTA, which is approved for relapsed or refractory large B-cell lymphoma.

  • Risks Related to Regulatory Approval and Government Regulation

    We may not receive the 12 years of data exclusivity from our anticipated Reference Product Exclusivity or data exclusivity in other jurisdictions

    The FDA has not yet awarded ZYNLONTA 12 years of Reference Product Exclusivity as the first loncastuximab tesirine product.

  • Risks Related to Commercialization and Manufacturing

    Our products and product candidates are complex and difficult to manufacture

    Our products and product candidates are complex to manufacture, and minor deviations can cause lot failures, recalls, or supply shortages.
