Parsing a text string in Excel

I have the following strings of text in Excel cells and need to get the value with the "%" symbol. I have tried several approaches with FIND, MID, LEN, SUBSTITUTE, etc., but haven't found the solution yet.

99.3SN .7CU 1% LV-1000 ON TAPE             (I need "1%")         
96.5SN 3AG .5CU .5% LV1000 SPECIAL SHAPE   (I need ".5%")      
96.5SN 3AG .5CU .5% LV1000 SPECIAL SHAPE   (I need ".5%")
96.5SN 3.5AG .75-1% LV-1000 ON TRAY        (I need ".75-1%")
92.5PB 5SN 2.5AG .75% LV-1000              (I need ".75%")

Any help to point me in the right direction would be greatly appreciated.

You can achieve it with a simple formula after installing reg-ex add-in:

=RegExFind(A1,"[-.0-9]*%")
