Best case scenario is that they recover in a few years, as they'll receive a massive influx of money from sales, recovery efforts, and insurance. They'll also be able to sue the guy who did it for everything he owns and more.
However, the most likely scenario is that KyoAni won't recover. This isn't just the loss of an office, but of animators, artists, and support personnel as well as months, if not years, of animation material and assets.
Another company may purchase them and their properties, but I doubt we'll see a full recovery anytime soon.
