Smith Micro Software Reports Fourth Quarter and Fiscal Year 2013 Financial Results

Aliso Viejo, CA, March 6, 2014 – 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, 2013.

“We achieved a 35 percent sequential increase in fourth quarter revenues, primarily due to new revenues from a leading chipset manufacturer and a strong holiday season for our productivity and graphics products,” said William W. Smith Jr., President and CEO of Smith Micro Software. “Fourth quarter revenues were down approximately 2 percent from the same quarter last year, but we saw a total year-over-year increase in our CommSuite, NetWise, and Productivity & Graphics product lines totaling $4.6 million. In addition, fourth quarter non-GAAP loss per share improved from $0.06 in 2012 to $0.01 loss per share in 2013, reflecting the positive impact of our third quarter restructuring.”

Smith Micro reported revenues of $11.8 million for the fourth quarter ended December 31, 2013, compared to $12.0 million reported in the fourth quarter of 2012.

Fourth quarter 2013 gross profit on both a GAAP and non-GAAP basis (which excludes stock compensation) was $9.5 million, compared to $9.7 million reported in the fourth quarter of 2012.

GAAP and non-GAAP gross profit as a percentage of revenues was 80.0 percent for the fourth quarter of 2013, compared to 80.6 percent on both a GAAP and non-GAAP basis for the fourth quarter of 2012.

GAAP net loss for the fourth quarter of 2013 was $1.5 million, or $0.04 loss per share, compared to GAAP net loss of $4.1 million, or $0.12 loss per share, for the fourth quarter of 2012.

Non-GAAP net loss (which excludes stock compensation and non-cash tax expense) for the fourth quarter of 2013 was $0.4 million, or $0.01 loss per share, compared to a non-GAAP net loss of $2.2 million, or $0.06 loss per share, for the fourth quarter of 2012.

For the fiscal year ended December 31, 2013, the Company reported revenues of $42.7 million, compared to $43.3 million for fiscal year 2012.

Fiscal year 2013 gross profit on both a GAAP and non-GAAP basis (which excludes stock compensation) was $33.0 million, compared to $34.9 million on both a GAAP and non-GAAP basis for the fiscal year 2012.

GAAP and non-GAAP gross profit as a percentage of revenues was 77.3 percent for fiscal year 2013 compared to 80.5 percent for the fiscal year 2012.

GAAP net loss for the fiscal year ended December 31, 2013 was $28.0 million, or $0.76 loss per share, compared to a net loss of $25.5 million, or $0.71 loss per share, for fiscal year 2012. GAAP net loss for fiscal 2013 includes a one-time charge to expense of $5.6 million for restructuring recorded in the third quarter.

Non-GAAP net loss (which excludes stock compensation and non-cash tax expense) for the fiscal year ended December 31, 2013 was $14.8 million, or $0.40 loss per share, compared to a non-GAAP net loss of $13.4 million, or $0.37 loss per share, for fiscal year 2012. Excluding the one-time restructuring charge, the non-GAAP loss per share would have been $0.31 for fiscal year 2013.

Total cash and cash equivalents and short-term investments at December 31, 2013 were $14.8 million.

The Company uses a non-GAAP reconciliation of gross profit, loss before 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 stock-based compensation 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 fiscal fourth quarter and year 2013 was computed by using a tax rate of 38 percent using the Company’s normalized 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.
