RE:Nice An increase in Working Capital does not necessarily mean that they made a profit. In fact a company's working capital can increase at the same time as they have ongoing negative earnings and a decrease in net shareholder equity
Working Capital can increase for any one or more of the following reasons,
1) Positive earnings (Profit)
2) The selling of shares or exercising of like vehicles (Warrants etc)
3)New loans, if those loans are classified as a long term liability.
4) The reclassification of long term locked in assets to current liquid assets (Cash and cash equivalents).
5) The reclassification of current liabilities to long term liabilities
