Stepinfo for time delayed systems

I have time delayed system. For example,

G(s)=(1/(s+1))*e^-2s

The system has 2 second time delay. How can I find stepinfo data?

s = tf('s');
G = (1/(s+1))*exp(-2*s)

G =
 
                1
  exp(-2*s) * -----
              s + 1
 
Continuous-time transfer function.

% Step response information
step(G)

stepinfo(G)

ans = struct with fields:
         RiseTime: 2.1973
    TransientTime: 5.9123
     SettlingTime: 5.9123
      SettlingMin: 0.9026
      SettlingMax: 0.9999
        Overshoot: 0
       Undershoot: 0
             Peak: 0.9999
         PeakTime: 11.4669

% Time delay of the system
G.InputDelay

ans = 2
