“We achieved our sixth consecutive quarter of record revenue growth in the third quarter and delivered outstanding bottom-line results,” said William W.

Smith Micro reported record revenue of $34.0 million for the third quarter ended September 30, 2010, a 22.2% increase over the $27.8 million reported in the third quarter ended September 30, 2009.

Third quarter gross profit on a GAAP basis of $30.2 million increased $5.9 million, or 24.5%, from the third quarter ended September 30, 2009.

Non-GAAP net income for the third quarter of 2010 increased to $7.9 million, or $0.23 per diluted share, compared to $6.6 million, or $0.20 per diluted share, reported in the third quarter of 2009.

Fully diluted weighted average common shares outstanding as of September 30, 2010, were 34.7 million compared to 33.1 million weighted average common shares outstanding as of September 30, 2009.

For the nine months ended September 30, 2010, the Company reported revenues of $95.2 million, a 22.7% increase from $77.6 million for the nine months ended September 30, 2009.

GAAP gross profit of $83.8 million increased $18.2 million, or 27.7%, for the nine months ended September 30, 2010, compared to $65.6 million for the nine months ended September 30, 2009. Non-GAAP gross profit (which excludes amortization of intangibles, stock compensation and non-cash tax expense) was $88.4 million for the nine months ended September 30, 2010, an increase of $19.1 million, or 27.5%, from the same period last year.

million, or $0.60 per diluted share, as compared to $16.2 million, or $0.50 per diluted share, for the nine months ended September 30, 2009.

Total cash, cash equivalents, and short-term investments have increased $11.7 million during the first nine months of the year to $57.5 million.

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