Largest Variety of Data Sources

Chelmsford, Mass.—August 28, 2013—Datawatch Corporation (NASDAQ-CM: DWCH), the leading global provider of information optimization solutions, today completed its acquisition of Panopticon Software AB, a privately held company based in Stockholm, Sweden and an industry leader in real-time visual data discovery solutions. Former Panopticon shareholders will receive Datawatch shares representing up to 23.6% of the total Datawatch shares outstanding following the closing of the transaction, determined on an adjusted basis. Panopticon is now a direct, wholly-owned subsidiary of Datawatch.

“The Datawatch/Panopticon combination is a great fit strategically and culturally,” said Michael A. Morrison, president and chief executive officer of Datawatch. “Bringing together the leaders in information optimization and real-time visual data discovery will empower our customers to optimize the value of virtually any data, and now do it at the speed their businesses operate – even if that means in real-time.

“We’ve brought together two teams that share the same passion for innovation and commitment to customer success. We’ve added another 25 industry veterans to an already very strong Datawatch team – further solidifying our position as the experts in delivering transformative business value to our customers.”
