Jason Hart, CEO of ActivIdentity, said, “The financial performance for this quarter is in line with our previously stated guidance and we continue to concentrate on improving these results moving forward. Management is focusing the business on achieving top line revenue growth, operational expense control, improved internal communication and simplification of the business”.

“We remain focused on reducing operating costs commensurate with our revenue levels.

“Deferred revenue grew during the quarter and we are pleased with our global reseller announcement with Sun Microsystems Inc. and the selection of our solutions for its internal use.

“We expect to continue to improve our position in the overall market and to strengthen our qualified sales pipeline. We anticipate that our previous successes with our high-end government solutions will assist us in increasing our sales activity predominantly outside of the United States, as evident with our selection in multiple government to

citizen identification pilot projects, which if successful, may result in large government-to-citizen deals in forward years. While we remain dissatisfied with the actual sales we achieved in the US Government and commercial markets (specifically the HSPD #12 initiative), the twelve month outlook for HSPD #12 remains promising. We continue to utilize our work and experience with the HSPD #12 initiatives in other sales opportunities.” Hart said.
