INSIGNIA SOLUTIONS REPORTS SECOND QUARTER 2004

FINANCIAL RESULTS

-Insignia Concludes Remaining Stake in JVM Business-

FREMONT, Calif., July 27, 2004– Insignia Solutions (Nasdaq: INSG) today reported financial results for the second quarter ended June 30, 2004.

Insignia reported second quarter net revenues of $107,000 from the ongoing launch and commercialization of the Company’s new technology, Secure System Provisioning (SSP) for Over-The-Air Repair of a growing, complex and diverse community of mobile devices.  The net loss in the second quarter was $1.3 million, or $0.04 per share.  As of June 30, 2004, the Company’s cash and cash equivalents was $2.0 million.

In the first half of 2004, Insignia reported revenue of $426,000.  The net loss for the six months ended June 30, 2004 was $3.2 million, or $0.11 per share.

On June 30, 2004, Insignia and esmertec, a Swiss software company focused on Java technologies, entered into a Termination and Waiver Agreement, effectively concluding the remaining business between the two companies and dissolving any ties going forward between Insignia and the Java Virtual Machine (JVM) product line it sold to esmertec in April 2003.  As a result, esmertec agreed to pay Insignia $185,000 on July 8, 2004 in full and final satisfaction of the deferred consideration and waived all other consideration pursuant to the Asset Purchase Agreement dated March 4, 2003.  The new agreement accelerated the termination under the Asset Purchase Agreement from March 2006 to June 30, 2004.  All existing and future outstanding obligations between the two companies were waived resulting in net other income of $298,000 to Insignia.

Mark McMillan, chief executive officer of Insignia Solutions, commented, “Lengthening sales cycles that followed the industry’s April 2004 ratification of mobile device management standards resulted in lower than expected second quarter revenues from our client software.  These standards will assure greater interoperability between server and client technologies and to date, as expected, have resulted in increased interest by mobile network operators in Insignia’s SSP solution while accelerating carrier requirements in our infrastructure technologies.

Due to the shift in our expectations of the timing of client software sales, we feel that it is imperative to extend the outlook for profitability that we provided in 2003 when we were first introducing our SSP solution to the market.  Consequently, we may also consider various financing alternatives.”

Recent Highlights:

•In a separate release today, the Company announced that a third Chinese handset manufacturer, Haier, has licensed Insignia’s SSP On Demand.  Accord Customer Care Solutions (Suzhou) Co., Ltd., a wholly owned subsidiary of Accord Customer Care Solutions Limited (ACCS), will provide the Insignia Secure System Provisioning (SSP) On Demand to Haier as a hosted service.

•As noted above, in June 2004, Insignia Solutions concluded its remaining business with Switzerland-based esmertec, effectively and entirely concluding the sale of its prior JVM product line to esmertec.

•In May 2004, Insignia announced the signing of a definitive agreement with Teleca to combine its industry leading Over-The-Air Repair(TM) technology with Teleca’s IOTA client products to benefit mobile operators and users worldwide. IOTA (IP-based over-the-air activation) is a CDMA industry standard developed by members of the CDMA Development Group to allow the network to provision the device with all the parameters required for the subscriber to access all available services in a secure manner.

•On May 25, 2004, the Company announced Insignia Open Management Client(TM), a new standards-based software product for mobile phones. This enables comprehensive mobile device management, including Over-the-Air Repair(TM), across different types of mobile networks.
