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: ▼23%; Now £31.2m
Cash at bank: ▼72%; Now £3m
Headcount: ▲13%; Now 203
Deferred income: ▼14%; Now £2.6m
Fixed assets: ▼12%; Now £6.8m

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