Chelsea Green Publishing--Bought Out?

Looks like one of my favorite publishers is no longer employee-owned, as I was so proud of it for being. In fact, it seems to be corporation-owned now:

In 2019 Chelsea Green became a 100% employee-owned company through its ESOP plan until May 2024 when the company was purchased by Rizzoli International Publications, the preeminent publisher of high-quality illustrated books, based in New York and part of the leading Italian publisher Mondadori Group.  

And if I try to preorder something, it gives me a "cart.penguinrandomhouse.com/prhcart" url.

Wow.

Are they using penguin distribution network or are they owned by the same people?  

I was curious so I did some looking around and found this -

It looks like it's being bought out by Rizzoli International Publications in New York City. The article says they'll keep everyone on, but they'll work for the new company now.
