SMITH MICRO SOFTWARE REPORTS RECORD FOURTH QUARTER AND FISCAL YEAR
2008 RESULTS

Net Revenues For Fiscal Year 2008 Increased 34% to a Record $98.4 Million, Fourth Quarter Net
Revenues Increased to $26.5 Million and Fourth Quarter EPS of $0.04 GAAP,
$0.28 Non-GAAP

ALISO VIEJO, CA, March 5, 2008 — Smith Micro Software, Inc. (NASDAQ: SMSI), a leading developer and marketer of software solutions and services for the mobility market, today reported its financial results for the fiscal 2008 fourth quarter and full year ending December 31, 2008.

“We are very pleased to report our fourth consecutive year of record revenue growth” said William W. Smith Jr., President and CEO of Smith Micro Software, Inc. “During the fiscal year, we achieved several key milestones as we strengthened our overall business model. We signed a record number of new customers, expanding our overall market opportunities and increased our leadership role in the wireless software space.”

Mr. Smith continued, “Our Connectivity & Security products continued to be our strongest contributor, where revenues increased from $29.6 million in 2007 to $58.7 million in 2008, a 98% increase. Specifically, during the second half of 2008, we expanded our market leadership in connectivity by adding two new WiMAX customers as well as one of the world’s largest PC manufacturers.”

Mr. Smith concluded, “Although we cannot control the current macro economic environment, we believe we have positioned the company well to continue on our growth plan. We enter 2009 with a very strong balance sheet and an industry-leading product portfolio that will continue to attract new customers—and grow existing relationships—as we build on the momentum we have created.”

Smith Micro reported net revenues of $26.5 million for the fourth quarter ended December 31, 2008, a 32.4% increase when compared to the $20.0 million reported for the fourth quarter of 2007.

Fourth quarter gross profit on a GAAP basis of $22.1 million increased $6.7 million, or 43.9%, from the fourth quarter ended December 31, 2007. On a non-GAAP basis (excluding amortization of intangibles, stock-based compensation and non-cash tax expense), gross profit was $23.2 million, an increase of $7.4 million, or 46.3%, from the same period last year.

GAAP gross profit margin was 83.6% of net revenues for the fourth quarter of 2008 as compared with 77.0% for the same period last year, and non-GAAP gross margin was 87.8% for the fourth

quarter of 2008 compared to 79.5% for the fourth quarter of 2007.

GAAP profit before taxes for the fourth quarter of 2008 was $3.2 million or $0.11 per diluted share. GAAP taxes, which are not cash based taxes, or what the Company will pay in taxes in 2008, were $1.9 million for the quarter. As such, the Company reported a GAAP profit of $1.3 million or $0.04 per diluted share for the fourth quarter of 2008, compared to $0.7 million or $0.02 per diluted share for the same period last year.

Non-GAAP net income for the fourth quarter of 2008, which includes an estimate of expected cash based taxes for 2009, was $9.0 million or $0.28 per diluted share, as compared to $7.8 million or $0.25 per diluted share for the quarter ended December 31, 2007.

Fully diluted shares outstanding for the quarter ended December 31, 2008 were 31.7 million as compared to 31.2 million shares outstanding for the quarter ended December 31, 2007.

For the fiscal year ended December 31, 2008 the Company reported net revenues of $98.4 million, a 34.1% increase when compared to the $73.4 million reported for the fiscal year ended December 31, 2007.

Full year gross profit on a GAAP basis of $78.3 million increased $25.6 million, or 48.5%, from the $52.7 million reported for the fiscal year ended December 31, 2007.

On a non-GAAP basis (which excludes amortization of intangibles, stock-based compensation and non-cash tax expense), gross profit was $82.5 million, an increase of $27.9 million, or 51.1%, from the same period last year.

GAAP net loss for the fiscal year ended December 31, 2008 was $0.7 million or $0.02 loss per diluted share primarily due to non-cash charges for amortization related to acquisitions, stock-based compensation expense, and non-cash tax expense. Non-GAAP net income for the fiscal year ended December 31, 2008 was $21.7 million or $0.69 per diluted share, as compared to $25.9 million or $0.84 per diluted share for the fiscal year ended December 31, 2007.

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-GAAP financial measures as reported by Smith Micro Software may not be comparable to similarly titled amounts reported by other companies.

Total cash, cash equivalents, and short-term investments at December 31, 2008 increased to $36.6 million, which compared to $31.2 million at September 30, 2008. Diluted shares outstanding as of December 31, 2008 were 31.0 million, essentially the same shares outstanding as of December 31, 2007.
