Lyft has a 1.2B cash reserve, ~400MM/yr in revenue, isn't profitable, and has now hit the end of the line on "unicorn" infusions at favorable terms. It's locked in a total war with Uber, which it cannot win or even stalemate while simultaneously shielding its reserves to keep an adequate runway to profitability.
So, since it can't win the race against Uber, its prospects are greatly diminished, and the greatest value it might hold is as someone else's strategic asset.
Or is it something more fundamental than that?
