Well I'd say it better be significant - its a 20% dilution and larger than anything they have done in the past.
I'm all in favor of growth, BUT I'm still waiting to see the benefit from the last major acquisition (ie increased dividend). Shareholders should be concerned that this doesn't turn into something too large for them to manage - but large enough to generate tons of management fees for themselves.
Given the large holding by the CEO I'm fairly comfortable but its worth keeping an eye on after they acquire whatever is in the works. Large acquisitions should filter down to shareholders in the form of increased dividends.
