Understand how the business earns
Start with products, customers, competitive position and the resources needed to operate. Ask what drives revenue, how concentrated demand is and whether the business can sustain its margins. A valuation model is more useful when its inputs reflect an understandable commercial story.
Follow earnings through to cash
Review operating cash generation, working-capital movements, investment requirements and debt obligations together. Compare accounting profit with cash conversion over time. Changes deserve an explanation before they are assumed to represent a lasting trend.
Separate an estimate from a decision
An estimate of value depends on assumptions and a specific date. Test the conclusion against changes in growth, margins and risk, and distinguish it from the price available in a negotiation or market. These questions are a framework for understanding a business, not a recommendation to buy or sell a security.
