It seems become common that newish listed companies were underperformed.
XIP, acquired Griffith Hack for $152m by issuing shares at $2.40/share. Those participants would be burnt badly.
The large acquisition is usually associated with synegisation issues, the 9-25% shortfall, is enough to cause sell-off, although previous price fall might have already factored in some, imo.

Another similar company, MUA, you might wanna check their performance upon the trade update 25 & 26 July 2017.
Cheers.
