First Quarter Financial Discussion:

“We are very pleased to announce another strong quarter with record revenues and pro forma earnings,” said William W. Smith, Jr., President and Chief Executive Officer of Smith Micro Software. “During the quarter, we achieved strong performance in all areas of our revenue plan. Our recently announced music essentials product kit was a significant contributor and our core connection manager product shipped in record quantities. We continue to make progress with our aggressive approach to broadening our product reach and expanding our customer base. Our Consumers Product Group’s (formerly the Allume Group) product line continues to consistently contribute to revenue and we continue to make headway in developing our StuffIt Wireless solution for our carrier and handset customers.

“We are also very excited about our recent acquisition of PhoTags, Inc., a leading developer and marketer of revolutionary photo and music management technology. Like Allume, we believe PhoTags offers us a significant opportunity to expand our product offerings to our wireless carriers and handset customers.

“With our array of new product solutions entering the wireless market arena and the significant growth in the Broadband Wireless market, we remain very optimistic about our ability to continue to post strong revenue and earnings performances throughout the remainder of the year.” Mr. Smith concluded.

Smith Micro reported record net revenue of $9.9 million for the first quarter ended March 31, 2006, a 24% increase over revenue of $8.0 million in the fourth quarter of 2005 and nearly five times the $2.0 million recorded in the first quarter of 2005.

Pro forma net income for the first quarter was $2.9 million, or $0.12 per fully diluted share, compared to pro forma net income of $2.6 million, or $0.11 per fully diluted share in the fourth quarter of 2005 and a net loss of $128,000, or a loss of $0.01 per share, in the first quarter of 2005. First quarter results in accordance with generally accepted accounting principles include approximately $700,000 of stock compensation expense relating primarily to the adoption of SFAS 123(R). First quarter fully diluted comparative results take into account a significant increase in the company’s share count year-over-year. Fully diluted shares outstanding as of March 31, 2006 were 24.3 million versus 19.7 million shares in the first quarter of 2005.

Total cash and equivalents at March 31, 2006 were $26.0 million, up $4.8 million from the 2005 fourth quarter ended December 31, 2005.
