SMSI Q4 2012 Earnings

Smith Micro Software Reports Fourth Quarter

and Fiscal Year 2012 Financial Results

ALISO VIEJO, CA, February 13, 2013 – Smith Micro Software, Inc. (NASDAQ:SMSI), a leading provider of wireless and mobility solutions, today reported financial results for the fourth quarter and full year ended December 31, 2012.

“Our fourth quarter revenues of $12.0 million were up 7.1% from the same period last year, and up 9.3% from the third quarter of 2012, primarily due to continued growth in our CommSuite solutions, which allow wireless carriers to capitalize on the convenience and stickiness of Visual Voicemail and Voice-to-Text applications,” said William W. Smith Jr., President and CEO of Smith Micro Software. “Our fourth quarter non-GAAP loss per share of $0.06 was cut in half from last year’s $0.12 loss per share due to higher revenues and on-going cost containment efforts. While we were disappointed in our total year revenue decline in 2012 versus 2011, we are encouraged by the year-over-year increase of $6.9 million in our newer NetWise and CommSuite product lines and the sequential growth of revenue throughout 2012.”

Smith Micro reported revenues of $12.0 million for the fourth quarter ended December 31, 2012, a 7.1% increase from revenues of $11.2 million reported in the fourth quarter of 2011.

Fourth quarter 2012 gross profit on a GAAP and non-GAAP basis (which excludes stock compensation) was $9.7 million compared to $8.5 million reported in the fourth quarter of 2011.

GAAP gross profit as a percentage of revenues was 80.6% for the fourth quarter of 2012 compared to 75.7% for the fourth quarter of 2011. Non-GAAP gross profit as a percentage of revenues was 80.6% for the fourth quarter of 2012 compared to 75.8% for the same quarter last year.

GAAP net loss for the fourth quarter of 2012 was $4.1 million, or $0.12 loss per diluted share compared to GAAP net loss of $9.5 million, or $0.27 loss per diluted share for the fourth quarter of 2011.

Non-GAAP net loss (which excludes stock compensation and non-cash tax expense) for the fourth quarter of 2012 was $2.2 million, or $0.06 loss per diluted share compared to a non-GAAP net loss of $4.2 million, or $0.12 loss per diluted share, for the fourth quarter of 2011.

For the fiscal year ended December 31, 2012, the Company reported revenues of $43.3 million, a 25% decrease from revenues of $57.8 million reported for fiscal year 2011.

Fiscal year 2012 gross profit on a GAAP basis was $34.9 million compared to $44.0 million reported for fiscal year 2011. On a non-GAAP basis (which excludes stock compensation for both years and amortization of intangibles for 2011), gross profit was $34.9 million for the fiscal year 2012 compared to $47.8 million for the fiscal year 2011.

GAAP gross profit as a percentage of revenues was 80.5% for fiscal year 2012 compared to 76.2% for the fiscal year 2011. Non-GAAP gross profit as a percentage of revenues was 80.5% for fiscal year 2012 compared to 82.8% for fiscal year 2011.

GAAP net loss for the fiscal year ended December 31, 2012 was $25.5 million, or $0.71 loss per diluted share compared to a net loss of $159.6 million, or $4.48 loss per diluted share for fiscal year 2011. In fiscal year 2011, we took an after-tax impairment charge for goodwill and other long-lived assets and deferred tax allowances of $124.3 million.

Non-GAAP net loss (which excludes stock compensation and non-cash tax expense for both years and amortization of intangibles and impairment of goodwill and long-lived assets for 2011) for the fiscal year ended December 31, 2012 was $13.4 million, or $0.37 loss per diluted share, compared to a non-GAAP net loss of $23.9 million, or $0.67 loss per diluted share, for fiscal year 2011.

Total cash and cash equivalents and short-term investments at December 31, 2012 were $32.2 million.

The Company uses a non-GAAP reconciliation of gross profit, loss before provision for income taxes, net loss and loss 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, goodwill and long-lived asset impairment and non-cash tax expense are excluded from the non-GAAP earnings calculation. Since we are in a loss position, the non-GAAP income tax benefit for the year ended December 31, 2012 was computed by

using a tax rate of 37.7% using the Company’s combined U.S. federal, state and foreign statutory tax rates less various tax adjustments. This presentation may be considered more indicative of our ongoing operational performance. The tables below present the differences between non-GAAP earnings and net loss 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.
