Indirect — not revenue

Balance-sheet signals

Year-on-year changes in filed balance-sheet items. They can hint at momentum (or investment) but are not revenue or profit and must not be read as such.

Net assets: ▼74%; Now £4.7m
Cash at bank: ▲16%; Now £1.5m
Headcount: ▲24%; Now 181
Deferred income: ▲16%; Now £77.6m
Fixed assets: ▲73%; Now £8.4m

Deferred income is reported together with accruals in this filing (“accruals and deferred income”), so it is an approximate signal only.
