Generic Drug Revenue Forecasting

This question practices how to think about revenue modeling in healthcare when a company has no long operating history of its own. A strong answer should break the business into individual drugs, separate products already on the market from those still in the pipeline, and then build each product’s revenue from market size, generic penetration, competition, and pricing assumptions. Interviewers ask this because generic pharmaceuticals are driven by patent expiry, substitution dynamics, payer behavior, and competitive entry, so the candidate needs to show an ability to translate industry structure into a practical forecast rather than rely on a simple growth assumption.

It also tests whether the candidate can connect volume and price drivers, think through how market share shifts after launch, and understand why additional entrants tend to compress both share and pricing over time. In an investment banking interview, this is important because it shows commercial judgment, comfort with healthcare-specific drivers, and the ability to build a sensible bottom-up model when direct company data is limited.
