Infusion. Off-loading key properties within its portfolio will provide GameStop with a tremendous cash infusion in the very near term.
Cash not capital but same effect. Liquidity.
What you just posted has nothing to do with an infusion with this run-up - which is what you said (see your quote above). Even that article you listed from 7 months ago estimates that they would get $90 million - and that's just some joe schmoe's opinion (Seeking alpha articles are so-so at best for equity analysis). At $45/share (1/10th it is now), that $90 million would be less than 3% of their market cap. And they are still bleeding money every year. I think longer term this stock continues to trend back single digits but medium term I think ~$40 after this insane spike is done is probably about right.
