It's a joint venture between Cinemark and Pinstack. The theater side is, indeed, Cinemark.
They are not affiliated with Cinemark. In fact, Cinemark was looking to build there, but Strike+Reel got it instead.
It does have 'XD Screens' which are the same screen technology used in Cinemark theaters but I'm not sure if they are directly affiliated with the Cinemark brand.
