Splunk Blows Away Sales Forecast, Added 94 New Customers in Q2

Company Adds Two Senior Software Execs to Help Manage Rapid Growth

SAN FRANCISCO - July 9, 2008 - Splunk, the IT Search company, today announced results for the second quarter of 2008 ended June 30. The company hit its sales forecast for the quarter adding 94 new customers and upgrading 45 existing customer deployments to higher data indexing levels. The company ended the quarter with more than 750 enterprise, service provider and government agency customers.

The most active industries contributing to the quarter were online services, telecommunications, financials services, and government agencies. New customers include T-Systems (NASDAQ: TSYS), Goldman Sachs (NYSE: GS), the U.S. Government Printing Agency, and ValueClick (NASDAQ: VCLK). "Our customers' IT infrastructures have become incredibly complex, dynamic, service oriented, virtualized and mission critical," said Michael Baum Co-founder and CEO of Splunk. "IT operations, security and compliance expenses are climbing fast and existing approaches to IT management have failed them. IT Search is proving to be the weapon of choice in the modern data center. It's scalable, versatile and invaluable with its ability to keep up with change."

The second quarter also saw the introduction of Splunk 3.3 and support for Windows WMI remote management instrumentation and Windows Registry. New Splunk Applications built on the Splunk IT Search platform also shipped including Splunk for Virtual Server Management, Splunk for Windows Server Management and Splunk for Change Management, which won the Best of Interop Award at Interop Las Vegas 2008.

Two seasoned software industry executives joined Splunk this past quarter. Phil Oreste joined as VP Finance & Operations; he was most recently CFO of Workstream and before that President & COO of Blue Titan Software. Steve Sommer joined as VP Marketing, after having held similar roles at SuccessFactors, ArcSight, Portal Software, and Informix. "These highly experienced additions to our management team will better enable us to manage the rapid growth we're experiencing now that the IT Search product category has become a global, mainstream market," added Baum.
