IBM Z series mainframe Telum CPUs are designed by IBM but manufactured by Samsung. IBM no longer owns any fabs. I assume they have some kind of technology licensing deal.
It's a lab. It's where ASML brings up the prototype machine and gets it working, with IBM talent working out the problems and getting it ready for commercial operation. They won't make chips at scale there: the facility isn't designed for that part. The thing to understand here is that isn't a simple, clean, comprehensible business arrangement. The Albany facility is highly subsidized by the state. IBM has their hooks deep in the operation and occupation of the site. Such facilities are extraordinary with capabilities that talent that are unique and fabulously expensive. That's why ASML is there, and not just doing it in some village in the Netherlands. It's why when Obama, Biden, Trump or whomever tells ASML to whom they will and won't be selling hardware, ASML listens.

My understanding is that ASML's acquisition of Cymer in California (the actual EUV light source technology) in 2014 was only permitted under a strict technology sharing and export agreement with the US government. And that the technology development and production had to remain within the US.
The USA CHIPS Act and NY State have provided $100 billion+ in funding with the expectation that ASML's core R&D and "prototyping" like this will be done in the US in partnership with US companies (like IBM).
Per IBM: "IBM Research at Albany [...] includes more than 100,000 square feet of semiconductor fabrication space"
I guess that is technically a R&D fab not a production one, but they definitely have in house fabrication capability
