Holmes is, as I understand, not only CEO but also the majority shareholder and holds a class of stock with disproportional voting rights on top of that; so, but for a few layers of legal fiction, Theranos is Holmes.
It's an expensive to question to answer whether they are worth a second shot at this point.
My money is on no, the brand is tarnished, but some day the idea seems like it will resurface, and when it does whoever shows some more evidence of real technology will be quickly funded.
