Comp analysis adjustment for acquisition from 8K

Hey everyone,

New to WSO here. I am doing a comparable company analysis and had a little question. I noticed for one of the comps that an 8K came out since the latest 10q and reported a recent acquisition (all cash transaction). Obviously this will affect cash, debt (if taking on acquired company's debt), goodwill, outstanding shares, etc. I am googling around and can't seem to find such an example to make sure I'm doing it correctly. Would anyone be able to point me to a book or example that walks through how to adjust for a recent acquisition for a comp analysis?

Thank you!!
