Forming a bond is exothermic and breaking a bond is endothermic.

Bond formation is exothermic. Energy is released when bonds are formed. When a new bond is formed, there is a net lowering of energy and heat is released into the environment. It costs energy to break a bond so bond breaking is endothermic.

Forming a bond is exothermic because it releases energy whereas breaking a bond would require energy so it would be endothermic.
