They do! The largest one right now (which is also receiving a wide release, even) would be X (March 2022), then the prequel Pearl (September 2022), and the soon-to-be-sequel in 2023.
They spent probably less than $5M total on the 3 movies (and filmed all at once), and the first two have already brought in $25M at the box office. A pretty good indie success story.
