It sounds like the rewards are given at two times:

Definately: when the bar initially reached 100%. (I personally witnessed this)

And guessing from the way the forumnote is worded (my speculation based on the words I capitalized/bold'ed): It'll give you rewards when the Event ends on monday, if you've killed 1 or more MOAs. You could try to clear the entire planet, just to be on the safe side.

****************

- All Tenno who killed at least 1 Fusion Moa received a FROST PRIME BLUEPRINT and 100K Credits!

- It's not too late to participate... if you haven't participated yet, you still have until Monday 12pm EDT to kill some Fusion Moas in Europa and get the reward WHEN THE EVENT ENDS! ''Not unlocked? Join a friend who has it unlocked!''



I got the rewards when the bar hit 100%, and they were 100k Credits & the FrostPrime blueprint (the recipe requires FrostPRIMEhelm, FrostPRIMEchassis, and FrostPRIMEsystems & OrokinCell).


 * It is currently unknown how the PRIME helm/chassis/systems are obtained.  It's speculated that since Europa currently has no boss, that a boss will be created next patch for this purpose.
