Ann: May 2016 Investor Presentation-TPP.AX, page-16

Looks like panic, good and proper. Some (fundamental) perspective:

Almost no borrowings, lots of cash.
Great management
Business has been growing, but even just based on the past 12 months, FY15 NPAT is $6.7m so a PE of 6.6. The second half of FY15 saw revenues & profit grow - so the true current NPAT should be higher and PE even lower.

There will need to be some seriously bad news coming to justify this price decrease.
