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: ▲0%; Now £36.8m
Cash at bank: ▲35%; Now £5.2m
Headcount: ▼4%; Now 396
Deferred income: ▲38%; Now £3.2m
Fixed assets: ▼20%; Now £26.2m

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