Aliso Viejo, CA — September 14, 2009 — Smith Micro Software, Inc. (NASDAQ: SMSI), a leading developer and marketer of mobility solutions and services for the wireless market, and Core Mobility, Inc., a developer of mobility software and solutions, announced the signing of an Agreement and Plan of Merger whereby Smith Micro will acquire Core Mobility.

Consideration to be paid by Smith Micro for this transaction consists of $10 million cash and 700,000 shares of Smith Micro common stock. In addition, Core Mobility may have the ability to earn additional cash consideration in the form of an earn-out, contingent on achieving certain milestone deliverables for product development and deployment. The transaction is subject to certain closing conditions and expected to be completed in the fourth quarter of 2009.

Core Mobility has a rich portfolio of innovative technologies and mobile software products, having established ground-breaking mobility offerings for synchronization, back-up and restore of critical user data as well as push-to-talk software and visual voicemail services. Core Mobility’s portfolio serves wireless carriers and device manufacturers with mobile handset software, as well as hosted software-as-a-service solutions.

The Core Mobility products are designed to work across a broad spectrum of handset operating systems and platforms, including a rich array of feature phones and today’s most popular Smartphones. Their applications are targeted at improving mobile subscribers’ communications experience while enabling wireless operators to enhance customer loyalty and to generate new revenue streams.
