Yes SPP Harvester will be investing in WSA assuming they are in the money.

'Yes, we have received notification regarding the 2 week extension of the closing date for Western Areas Ltd SPP, and you are quite right noting that the current market price is trading above the SPP price. As the Western Areas SPP does not contain a Price Fall Protection Clause (meaning that the price of this SPP is fixed at $2.15 and will not be calculated as the lower of a fixed price and a discount to a price on, or leading up to the closing date of the SPP) SPP Harvester will only apply if the Western Areas ASX share price is greater than the SPP offer price of $2.15 on the SPP Harvester Acceptance Date (defined in our Terms and Conditions as the close price on 15 April 2021)'
