Can absolute risk be greater than 100%?

From the definition of absolute risk:

• AR (absolute risk) = the number of events (good or bad) in treated or control groups, divided by the number of people in that group.

What if the events happen multiple times to the treated group? Couldn't that mean absolute risk would be greater than 100%?

What is the numerator and what is the denominator?

I was using the following equation I came up which I thought was appropriate:
AR (absolute risk of adverse event) = RR (relative risk of adverse event) * AR (absolute risk of event in general population)

where in some cases the AR would be >100%
