Ann: EN1 Achieves Significant Cashflow Improvement Appendix 4C, page-6

And adding to that picture painted by @vontrader is that (as management have guided) most of the inventory purchases are made in H1 (actually Q1), so we see a disproportionately high negative cash flow in H1 and expect to see a disproportionately high positive cash flow in H2. As the 4C is a cash flow statement rather than a P&L, we see this inventory picture play out in the "product manufacturing and operational costs".

Proof of the pudding will be in the eating....but I am not inclined to disbelieve management guidance unless their track record encourages me to do so. Exciting H2 awaits, IMO.
