It's not entirely accurate.
You're right. They aren't closing. They are saying several different things which are hard to match up. There were rumors they were closing, and then it was stated they are suspending animation projects for a while and just focusing on licensing, with later information stating they are considering a restructuring.
This doesn't change that their last couple films simply haven't been as successful as they would like, and given their labor-heavy, traditional approach to animation, not to mention their focus on quality production and music as well, they don't make cheap movies.
The impression I've gotten from all this is that they are not where they want to be, and they are certain if they keep doing what they've been doing, they are going to start losing money and getting even further off-target. But there's another impression I get, and that is that they don't know what on-target is. They know they want to be creative and successful, but Hayao Miyazaki has been single-handedly carrying the studio for easily over a decade.
So now they need to go into very-low-expenditure mode while they figure out 1. what kind of company they want to be and 2. what it will take to make themselves into that company.
