SMITH MICRO SOFTWARE REPORTS 2008 FIRST QUARTER FINANCIAL RESULTS
Net Revenues Increase to a Company Record $21.9 Million

Aliso Viejo, Calif., May 7, 2008 — Smith Micro Software, Inc. (NASDAQ: SMSI), a leading developer and marketer of software solutions and services for the wireless market, today reported its 2008 first quarter financial results ending March 31, 2008.

“Smith Micro Software had a solid first quarter that represented a company record for the highest quarterly revenue in our history coming in at $21.9 million, an increase of 23.9% over last year’s first quarter results,” said William W. Smith Jr., President and CEO of Smith Micro Software, Inc. “During the quarter we concentrated heavily on integration of our prior acquisitions, and on new product development that will position us for continued growth throughout the year.”

Mr. Smith continued, “I am very pleased that all of our operating units continued to contribute to our overall financial results, especially the strong performance from our Connectivity & Security business segment that showed tremendous growth of nearly 80% year over year and our Consumer segment that grew nearly 98% year over year. Our product strategies resonate well with our customers and our ability to deliver products that help our customers reach their visions sets us apart from other software companies”.

Mr. Smith concluded, “We remain very optimistic and confident in our business case as we build our leadership position in the wireless software marketplace and expect 2008 to be a very successful year for the company.”

Smith Micro reported record net revenue of $21.9 million for the first quarter ended March 31, 2008, a 23.9% increase year over year and a 10% increase when compared to $20.0 million reported in the fourth quarter of 2007.

GAAP gross margin of $16.8 million increased $4.8 million or approximately 40% from the same period last year. On a non-GAAP basis (which excludes amortization of intangibles, stock compensation and non-cash tax expense), gross margin of $17.8 million increased $5.5 million or 45% from the same period last year.

Of key significance, while the Company’s revenue increased 23.9% year over year, gross margin dollars increased 40% from the same period last year on a GAAP basis and 45% on a non-GAAP basis, reflecting increasing leverage in Smith Micro’s financial model.

As follows, GAAP gross margin as a percentage of revenue was 76.6% for the first quarter of 2008 as compared with 67.9% for the same period last year and non GAAP gross margin as a percentage of revenue was approximately 81.4% for Q1 2008 compared to 69.6% for Q1 2007.

GAAP net loss for the period was approximately $317,000 or $0.01 per diluted share for Q1 2008 primarily due to non-cash charges for amortization related to acquisitions, stock compensation expense and non-recurring integration expenses related to the PCTEL MSG group acquisition which closed on January 4, 2008. Non GAAP net income for the first quarter of 2008 was $3.1 million or $0.10 per diluted share, or $3.8 million or $0.12 per diluted share taking into account non-recurring acquisition costs, as compared to $6.2 million or $0.20 per diluted share last year.

Fully diluted shares outstanding as of March 31, 2008 were 30.4 million as compared to 30.7 million shares outstanding as of March 31, 2007.

Total cash and equivalents at March 31, 2008 were $26.2 million, compared to $87.5 million at December 31, 2007. The reduction in cash is attributed to the January 4, 2008 acquisition of the PCTEL MSG group.

The Company uses a non-GAAP reconciliation of net income and earnings per share in the presentation of financial results in this press release. Management believes that this presentation may be more meaningful in analyzing our income generation, since amortization of intangibles from acquisitions, stock-based compensation, and non-cash tax expense are excluded from the non-GAAP earnings calculation. This presentation may be considered more indicative of our ongoing operational performance. The tables below present the differences between non-GAAP earnings and net income on an absolute and per-share basis. Non-GAAP financial measures should not be considered in

isolation from, or as a substitute for, financial information presented in compliance with GAAP, and the non-financial measures as reported by Smith Micro Software may not be comparable to similarly titled amounts reported by other companies.
