A compound having high heat of formation indicates a higher amount of energy is released during the formation of the compound so the compound formed will have lower energy and hence it will be more stable.

@Ankit Saini.
It is not always necessary that heat is released during the formation, it may also be absorbed.

Higher values of heat of formation (that is higher magnitude - negative values) , indicates a higher amount of energy released during the formation of a compound, which makes it more stable.
For example, if the enthalpy of formation of a compound AB is -1000 kJ/mol and that of AC is -1200 kJ/mol, AC is more stable than AB.
