SMITH MICRO SOFTWARE REPORTS RECORD REVENUE QUARTER

Revenues Increase 21% to a Company Record $31.4 Million;
Second Quarter Diluted EPS of $0.05 GAAP, $0.20 Non-GAAP

Aliso Viejo, CA, August 4, 2010 — 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 2010 second quarter ended June 30, 2010.

“Smith Micro had an exceptional quarter with another solid financial performance, as we delivered the highest quarterly revenue results in the Company’s history,” said William W. Smith Jr., President and CEO of Smith Micro Software. “Our wireless and mobility unit continued to be the strong growth driver for the Company as revenues increased 33% over last year, as we saw strength across all products categories within this business segment.”

Mr. Smith continued, “In addition to achieving solid revenue growth and strong earnings, we continued to build a market leading mobile software portfolio designed to help us meet the demand for mobile broadband services in the coming years. We are delivering results today while investing in the future and we are confident in the opportunities we see ahead.”

Smith Micro reported record revenues of $31.4 million for the second quarter ended June 30, 2010, a 21% increase over the $26.0 million reported in the second quarter ended June 30, 2009.

2010 second quarter gross profit on a GAAP basis of $27.4 million increased $5.3 million, or 24%, from the second quarter ended June 30, 2009. On a non-GAAP basis (which excludes amortization of intangibles, stock compensation and non-cash tax expense), 2010 second quarter gross profit was $28.9 million, an increase of $5.6 million, or 24%, from the same quarter last year.

GAAP gross profit as a percentage of revenue was 87.4% for the second quarter of 2010, compared with 84.9% for the same quarter last year. Non-GAAP gross profit as a percentage of revenue was 92.3% for the second quarter of 2010, compared to 89.7% for the same quarter last year.

GAAP net income for the second quarter of 2010 increased to $1.9 million or $0.05 per diluted share, compared to a GAAP net income for the second quarter of 2009 of $1.3 million, or $0.04 per diluted share.

Non-GAAP net income for the second quarter of 2010 increased 23% to $6.8 million, or $0.20 per diluted share, compared to $5.6 million, or $0.17 per diluted share, reported in the second quarter of 2009.

Fully diluted weighted average common shares outstanding as of June 30, 2010 were 34.8 million compared to 33.0 million weighted average common shares outstanding as of June 30, 2009.

For the six months ended June 30, 2010, the Company reported revenues of $61.2 million, a 23% increase from $49.8 million for the six months ended June 30, 2009.

GAAP gross profit of $53.5 million increased $12.2 million, or 30%, for the six months ended June 30, 2010 compared to $41.3 million for the six months ended June 30, 2009. 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 $56.6 million for the six months ended June 30, 2010, an increase of $12.8 million, or 29%, from the same period last year.

GAAP net income for the six months ended June 30, 2010 was $3.5 million, or $0.10 per diluted share, compared to a GAAP net income for the six months ended June 30, 2009 of $1.6 million, or a $0.05 per diluted share. Non-GAAP net income for the six months ended June 30, 2010 increased 35% to $13.0 million, or $0.38 per diluted share, as compared to $9.6 million, or $0.30 per diluted share, for the six months ended June 30, 2009.

Total cash, cash equivalents, and short-term investments have increased $9.0 million during the first

six months of the year to $54.8 million.

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

Financial Guidance:

Smith Micro Software is reiterating its previous guidance for fiscal year 2010 of revenue of $125 million to $135 million.
