AbbVie Inc.: 10-K Risk Factor Changes

Consolidation and vertical integration among PBMs, managed care organizations and other supply chain intermediaries has increased their purchasing power and ability to influence formulary placement and reimbursement levels. A limited number of these entities negotiate pricing, rebates and patient access terms on behalf of health plans and government programs that cover a significant portion of insured patients in the United States. 17 | 2025 Form 10-K 17 | 2025 Form 10-K 17 | 2025 Form 10-K 17 | 2025 Form 10-K These entities employ formulary management and utilization tools, including formulary exclusions, step therapy requirements, prior authorization protocols and tiered placement decisions, that could limit or delay patient access to our products, potentially increase patient cost-sharing and/or shift utilization to competing therapies. Unfavorable formulary decisions and increased utilization management restrictions could reduce prescription volumes and adversely affect our revenues. Further changes in formulary placement or access restrictions implemented by these intermediaries could occur with limited advance notice and may be difficult to predict or mitigate. PBM business practices, rebate structures and pricing arrangements are also subject to change as a result of enforcement actions, regulatory settlements, legislation or other government actions. Government-mandated changes to PBM rebate methodologies, formulary design or pricing transparency practices could affect our contractual arrangements with PBMs, alter manufacturer-PBM economic relationships or shift costs to manufacturers. Additionally, these entities may negotiate higher or additional rebates, discounts, administrative fees or other price concessions that could adversely affect our revenues and results of operations.
