are these sentences written correctly?

[KLPNO]

Hello everyone
I'd like to ask if the following 2 sentences are written correctly.

Also, there is an important reason why XXX entrusted medical examination of its employees to YYY. It is that YYY is the insurance company that provides all medical services for employees of XXX, and it has complete information about the health of XXX employees.

XXX and YYY are the names of the companies.
