Best buddies CP question

When you become best buddies with your Pokemon does that increase its CP? Because one of the reasons I picked my buddy is because I love the number of CP it has, I’m only 1 heart away from it being best buddies and I wanted to check.

Going to the game tonight and I flew into Seattle on the Mariner’s plane!

This is the best shot I could get sadly but hey! Thought it was pretty cool!
