Unfortunately you haven't provided enough information in order to receive a valid response to your question.
First of all;

- How large is this company that bought you out? Do they have their own AD infrastructure already in place? How large is your environment?
You can setup a forest trust with them.. or build a new forest and collapse both your forests into it. (Some design considerations need to be taken into account)

- How are you planning to connect to this other company (Site-Site VPN, Dedicated network links like MPLS, LANic, Metro Ethernet)
- The fact that you have 192.168.x.x addresses and they have 10.x.x.x address indicate that these are private networks that are NATed behind firewalls that have a public IP address space therefore some network design it required as well

I would strongly recommend that you engage some external help or rely on the other company's IT team (assuming they are qualified) to help you with the planning.
