SMITH MICRO SOFTWARE REPORTS RECORD FOURTH QUARTER
AND FISCAL YEAR 2009 FINANCIAL RESULTS
Revenues for Fiscal Year 2009 Increased to a Record $107.3 Million
Fourth Quarter Revenues Increased to a Record $29.7 Million

Aliso Viejo, CA, February 24, 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 the fiscal 2009 fourth quarter and full year ended December 31, 2009.

“We are very pleased with our record financial results achieved in the fourth quarter and for fiscal 2009,” said William W. Smith Jr., President and CEO of Smith Micro Software. “During the year we made significant progress strengthening our core wireless business which grew 22% year-over-year, while expanding our customer base and broadening our portfolio to meet the emerging demands in the growing broadband mobile and connectivity markets. Our accomplishments in 2009 and actions taken to concentrate our focus on delivering more intelligent and adaptive connected mobile solutions are key to our long term growth and profitability strategy. ”

Mr. Smith continued, “We enter 2010 with strong financial momentum, and we look forward to capitalizing on the coming deployments of 4G networks in North America and throughout the world. We are poised to build upon our successes in 2009 as we continue to deliver next generation intelligent wireless software solutions across the connectivity, communications and multimedia space.”

Smith Micro reported revenues of $29.7 million for the fourth quarter ended December 31, 2009; a 12% increase over $26.5 million reported in the fourth quarter of 2008.

Fourth quarter gross profit on a GAAP basis of $26.2 million increased $4.1 million, or 18%, from the fourth quarter of 2008. On a non-GAAP basis (which excludes amortization of intangibles, stock compensation and non-cash tax expense), fourth quarter gross profit was $27.6 million, an increase of $4.3 million, or 19%, from the same quarter last year.

GAAP gross profit, as a percentage of revenues was 88.2% for the fourth quarter of 2009, compared with

83.6% for the fourth quarter last year. Non-GAAP gross profit as a percentage of revenues was 92.9% for the fourth quarter of 2009, compared to 87.8% for the same quarter last year.

GAAP net income for the fourth quarter of 2009 was $1.2 million or $0.04 per diluted share compared to $1.3 million or $0.04 per diluted share for the fourth quarter of 2008.

Non-GAAP net income for the fourth quarter of 2009 was $8.9 million, or $0.26 per diluted share, compared to $9.0 million, or $0.28 per diluted share, for the fourth quarter of 2008.

Total cash and cash equivalents and short-term investments at December 31, 2009 increased $9.3 million in 2009 to $45.9 million, up from $36.6 million at December 31, 2008.

For the fiscal year ended December 31, 2009, the Company reported net revenues of $107.3 million, a 9% increase over net revenues of $98.4 million reported for fiscal 2008.

Full year gross profit on a GAAP basis of $91.8 million increased $13.5 million, or 17%, from $78.3 million reported for fiscal 2008.

On a non-GAAP basis (which excludes amortization of intangibles, stock-based compensation and non-cash tax expense), gross profit was $96.9 million, an increase of $14.4 million, or 18%, from the same period last year.

GAAP net income for the fiscal year ended December 31, 2009 was $4.8 million or $0.14 per diluted share, compared to a net loss of $0.7 million, or a loss of $0.02 per diluted share, for fiscal 2008. Non-GAAP net income for the fiscal year ended December 31, 2009 was $25.1 million, or $0.76 per diluted share, compared to non-GAAP net income of $21.7 million, or $0.69 per diluted share, for fiscal 2008.

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.
