Question on why our final signed email notification has three party names

We are using Power Automate and Adobe Sign to sent out files to be signed. There are two signers. One is internal and the other is external. This is working well except I noticed that after the two signings have been completed the final email back to me states the info below. Is anyone able to let me know why there are three names? Thank you.

Attached is the final agreement between:

My company name

Signer 1 name

Signer 2 name
