SMITH MICRO SOFTWARE REPORTS RECORD SECOND QUARTER
FINANCIAL RESULTS

Second Quarter 2009 Revenues Increase 11% to a Q2 Record of $26.0 Million;
EPS of $0.04 GAAP or $0.17 Non-GAAP

Aliso Viejo, CA, August 3, 2009 — Smith Micro Software, Inc. (NASDAQ: SMSI), a leading developer and marketer of software solutions and services for the mobility market, today reported financial results for its 2009 second quarter ended June 30, 2009.

“I am pleased to report another strong financial quarter for the company, where even in the current economic environment, we achieved record Q2 revenues of $26.0 million,” said William W. Smith Jr., President and CEO of Smith Micro Software. “Our second quarter results reflect the continued momentum we are generating in the marketplace with both new and existing customers led by our wireless business segment that grew 27% over last year to $21.4 million.”

Mr. Smith continued, “During the quarter we also significantly expanded our addressable market by signing our first cable operator that recently began offering mobile services. We also saw our carrier customers launch the first wave of Netbooks that are inherently designed for mobile connectivity. We look to expand our leadership as we capitalize on the opportunity to outfit these devices with our connectivity and security management solutions.”

Mr. Smith concluded, “We remain very optimistic about our business as we look to the remainder of our fiscal year 2009. We offer the leading software mobility platform in the marketplace today, and see significant opportunities in our business pipeline, as we continue to benefit from the strong growth of the broadband connectivity marketplace.”

Smith Micro reported revenues of $26.0 million for the second quarter ended June 30, 2009, an 11% increase over the $23.5 million reported in the second quarter ended June 30, 2008. This was a record revenue number for our fiscal second quarter.

Second quarter gross profit on a GAAP basis of $22.1 million increased $4.1 million, or 23%, from the second quarter ended June 30, 2008. On a non-GAAP basis (which excludes amortization of intangibles, stock compensation and non-cash tax expense), second quarter gross profit was $23.3 million, an increase of $4.3 million, or 23%, from the same quarter last year.

GAAP gross profit, as a percentage of revenues was 84.9% for the second quarter of 2009, compared with 76.7% for the same quarter last year. Non-GAAP gross profit as a percentage of revenues was 89.7% for the second quarter of 2009, compared to 81.0% for the same quarter last year.

GAAP net income for the second quarter of 2009 increased to $1.3 million or $0.04 per diluted share, compared to a GAAP net loss for the second quarter of 2008 of $0.2 million, or a $0.01 loss per diluted share.

Non-GAAP net income for the second quarter of 2009 increased 54% to $5.6 million, or $0.17 per diluted share, compared to $3.6 million, or $0.12 per diluted share, for the second quarter of 2008.

Total cash and cash equivalents and short-term investments increased $7.2 million during the first six months of 2009 to $43.8 million, up from $36.6 million at December 31, 2008.

For the six-months ended June 30, 2009, the Company reported revenues of $49.8 million, a 10% increase from $45.3 million for the six months ended June 30, 2008.

GAAP gross profit of $41.3 million increased $6.6 million, or 19%, for the six months ended June 30, 2009 compared to $34.7 million for the six months ended June 30, 2008. The increase in gross profit was primarily due to improved product margins resulting from a more favorable product mix.

Non-GAAP gross profit (which excludes amortization of intangibles, stock compensation and non-cash tax expense) was $43.8 million for the six months ended June 30, 2009, an increase of $7.0 million, or 19%, from the same period last year.

GAAP net income for the six months ended June 30, 2009 was $1.6 million, or $0.05 per diluted share, compared to a GAAP net loss for the six months ended June 30, 2008 of $0.5 million, or a $0.02 loss per diluted share. Non-GAAP net income for the six months ended June 30, 2009 increased 42% to $9.6 million, or $0.30 per diluted share, as compared to $6.7 million, or $0.22 per diluted share, for the six months ended June 30, 2008.

The Company uses a non-GAAP reconciliation of gross profit, 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.
