Perhaps "sen" is no more than a 1/100 sub-unit of the (e.g.) currency Malaysian ringgit? Such a sub-unit is called "sen", and is etymologically related to the English word "cent".
It seems even more likely that "sen" in "Earnings Per Share (sen)" refers to a 1/100 sub-unit of a currency, as the google query "Earnings Per Share (cents)" yields many similar results.
But even if that would be the case, I think there can be more elaborate answers than mine, which also explains a bit more about the meaning of the words "Earnings Per Share", in relation to numbers expressed in either "cents" or "sen".
