Watch

Operating Cash Flow Turns Negative

The most observable driver is the sharp reversal in operating cash flow from a positive to a negative figure, which directly caused free cash flow to turn negative despite lower capital expenditure.

If operating cash flow remains negative, the company may face pressure on liquidity and its ability to fund ongoing operations without external financing.
