It's simply that investors currently have no horizon to see increases in the SP for something like a year and most of them want to move on to something with a more immediate reward. The only bad news is no news essentially; this announcement flags that a sale is probably not in the near future as the currently available information attracted no serious offers. There will almost certainly need to be new information or development to attract a sale, and the announcement says that's approximately a year away.

If you evaluate the prospects positively, then a year away is peachy keeno, because it means you can buy today and lower the tax on those gains. If you don't evaluate the prospects especially positively, then, well, I mean frankly you shouldn't probably hold the stock. If you're here for pip trading and pump and dumps, the game's been called off and you need to move on to some new, whatever, lithium stock or something.
