What is a common method for projecting free cash flows over a forecast period?

Using historical data to inform future projections is a common method for projecting free cash flows over a forecast period because it allows analysts to base their forecasts on actual past performance. This approach involves examining historical revenue growth rates, margins, and capital expenditures to understand how the business has performed over different economic environments. By analyzing past trends, analysts can create more informed and realistic projections, adjusting for expected changes in the business environment or operational efficiencies.

Incorporating historical data is advantageous as it provides a grounded perspective on how various factors such as seasonality, industry developments, and economic cycles have influenced cash flows. This method ultimately helps in establishing a reliable baseline from which future cash flows can be estimated, ensuring that the projections reflect both the company's historical performance and any anticipated changes moving forward.
