Spectrum of an almost Hamiltonian matrix
I have now taken a simpler special case where the blocks on the diagonal are diagonal matrices.

Spectrum of an almost Hamiltonian matrix
Simplified the case to A being a diagonal matrix

Spectrum of an almost Hamiltonian matrix
Maybe a more explicit result since the matrices involved have extra structure.

Spectrum of an almost Hamiltonian matrix
@CarloBeenakker It doesn't work for generic case, thats why I am looking for additional hypothesis which makes the result true...something which relates eigenspaces of the other blocks with the eigendirection of the rank-1 $C$ ...maybe.

On the spectrum of Fokker–Planck with linear drift
@GiorgioMetafune Thanks, I see how we can derive the condition on $\lambda$ from the series formula. Do you any thoughts on the main claim ?

@williewong : does this also rule out bound states for values of $\lambda$ in the continous spectrum?
