With Atlus' parent company Index Corporation currently undergoing civil rehabilitation (the Japanese equivalent of bankruptcy), funds need to be raised to pay off their debts. They need to cover 24.5 billion yen worth of debt and so the company is being put up for auction.
Bloomberg Japan has reported that about 20 different companies have placed a bid for Index Corporation. Only one bid has been revealed so far, but it's a big one. Sega Sammy Holdings has reportedly bid 20 billion yen ($202.2 million USD) for the company. This number exceeds Index's original estimation of 15 billion yen from the sale, so this would be a huge boon to their civil rehabilitation goals.
We'll keep this thread updated if we find out the identity and prices of other bidders.
