Please correct my grammar

We first need to know what it means.

Seconding this sentiment. But for now? I'll drop this stab of a guess:
Our new target of $4 million has been set for June 30th, 2018. The team has been notified of this new goal.

The team's revised goal is $4 million in sales by the end of this financial year.

Unless it's meant to be:

The team's revised sales target is $4 million for the June Quarter.

Unless it's indecipherable.
