Business diagramming and technical drawing software house Visio Corp has announced it has acquired privately-held Kaspia Systems Inc, which develops network auditing software. Seattle-based Visio handed over 482,985 shares of its common stock in a deal that values Kaspia at roughly $23.3m. Kaspia, based in Beaverton, Oregon, is a 25-person company whose offerings include discovery, monitoring and reporting software. Visio will be keeping 15 Kaspia employees, including the entire development team. Visio will use the acquisition to enhance its products for documenting networks by adding new capabilities for automatically producing diagrams and tracking changes to enterprise networks. The company intends to incorporate Kaspia’s key autodiscovery technology into a future product offering, currently code-named Venice, which should be shipping by the end of the calendar year. Other key pieces of technology that the Kaspia deal brings, such as an auditing tool, statistical analysis system and a web report generator will be productized over the next 12 months as add- ons to Venice and may or may not be bundled together, according to the company. Visio said the deal, which will be accounted for as a pooling of interests, will be slightly dilutive to earnings for both the September and December quarters. Analysts surveyed by First Call had been expecting earnings per share of $0.31 and $0.35, respectively. The company will also book a $1.2m charge related to the merger during the September quarter.
