CAN I RESTORE FILES FROM FORMATTED MAC PRO 13

hello, my laptop got stolen and somehow I recuperated it as it was found on the street. apparently the people who stole it re-formatted it and deleted all my files. the company I work for does back up for emails, and files on our company servers. but all the files on my desktop have been deleted. also unfortunately my iCloud storage has been full since a few months back and I couldn't back up on iCloud. I am inquiring if I can retrieve my lost files in any way possible. thanks
