Argyle buys three companies

Argyle Security, a rapidly growing international integrator born out of the San Antonio-based ISI, has announced three buys just now. The total purchase price is $14 million, so none of them is a big move, but they have collectively caused the company to up its revenue projections from between $105 and $115 million to between $128 and $142 million. If they're paying $14 million for about $25 million in year one revenue, that's not too bad, right? I'll have more about this on the wire Thursday.
