As mentioned in the article on income statements
The income statement indicates the profitability of a company’s operations while the balance sheet reveals the financial health of a company at a given point of time. However, both these statements tend to ignore the cash generating capacity of a business, and profitability does not always guarantee liquidity. Generating cash over time is very much essential for a company’s long-term survival, as it is required for conducting day-to-day operations. Many firms have failed due to a lack of cash on hand, even though their operations have been profitable.
