Although I’ve given a JV the thought of some possibility, the company would still need to prepare in advance to remain independent. And there’s no evidence of them taking any steps in that direction.
There’s always risk associated with a JV or just waiting until manufacturing begins to entertain offers, even if there’s a potential for a higher payout later. Given all the reasons you cite, I agree the philosophy they’re taking is a bird in the hand is worth two in the bush.
