Investopedia explains Obsolete Inventory
Large amounts of obsolete inventory are a warning sign for investors: they can be symptomatic of poor products, poor management forecasts of demand, and poor inventory management. Looking at the amount of obsolete inventory a company creates will give investors an idea of how well the product is selling and of how effective the company's inventory process is.
