Title is misleading; it's not owned by Nintendo. This is the Renesas factory that was going to close (see article) due to low Wii U sales not covering its running costs.
The Sony deal will allow it to keep producing the Wii U component. Nintendo would otherwise have been forced to pay Renesas more to keep it open, since it can't be readily sourced from elsewhere.
