Annual run-rate

$2.6M

Steady. Annualised run-rate over the last four complete quarters is broadly level against the four quarters before it.

Contract value over time

Switch between annualised run-rate and raw award value

Annualised run-rate spreads each contract's value evenly across its term, so a multi-year renewal does not read as a spike in growth. Switch to raw award value to see the value booked on the day each contract was signed. Quarters past the last complete one are work already under contract, not a forecast.
