How much does a TC negatively affect SR?

As far as I'm aware, nobody builds a TC that properly translates focal length to the camera. This must surely have an affect on SR since it requires this information to perform properly.

If I put a 1.4x TC on my Sigma 100-300/4, how much will it hurt the amazing SR the K-5 brings to the table?

i haven't spent much time with the combination or even the camera but I know I'm not going to be happy shooting 400+mm unstabalized.
