Yes, it just calls NMaximize. It's the same for Integrate, Sum, and other such functions. For example:
In[1]:= Sum[Exp[-k]*Sin[k^2], {k,1,Infinity}]
2
Sin[k ]
Out[1]= Sum[-------, {k, 1, Infinity}]
k
E
In[2]:= N[%]
NIntegrate::ncvb: NIntegrate failed to converge to prescribed accuracy after 7
recursive bisections in k near k = 22.3143.
Out[2]= 0.218384
