You should read again their last financial statement.
Last I checked they had 60PH which was completely paid for.
They don't have that much money lying around and neither the facilities.

Also it doesn't make any sense to do it right now when they could've started 3 months ago.
However, we had not stopped our work on designing our own products and finding proper farms after our chips passed the tests.
