Smith Micro Reports 2016 First Quarter Financial Results

Growing pipeline positions company for strong second half of fiscal 2016

Aliso Viejo, CA, April 26, 2016 – Smith Micro Software, Inc. (NASDAQ:SMSI) today reported financial results for its first quarter ended March 31, 2016.

“Revenue for the first quarter of 2016 was $7.2 million, which was above previous guidance,” said William W. Smith Jr., President and CEO of Smith Micro Software. “We have managed our cash well, ending the quarter at $13.1 million, and we remain on track to accelerate our growth in the second half of the year based on the new agreements we signed during the fourth quarter of last year and a strong sales pipeline.”

“We completed the Birdstep acquisition on April 7, 2016. The integration is underway and we are very excited about the new opportunities, complementary technologies, and the talented team we gained as part of the transaction. We remain very optimistic as we look at the second half of the fiscal year, building momentum around new deals and the expansion of business with our current customers,” Mr. Smith concluded.

Fiscal First Quarter 2016 Financial Results:

Smith Micro Software reported revenue of $7.2 million for the first quarter ended March 31, 2016, compared to $10.5 million reported in the first quarter of 2015.

First quarter gross profit on a GAAP and non-GAAP (which excludes stock compensation) basis was $5.1 million, compared to $8.4 million reported in the first quarter of 2015.

GAAP and non-GAAP gross profit as a percentage of revenue was 70.7 percent for the first quarter of 2016, compared to 79.9 percent for the same quarter last year.

GAAP net loss for the first quarter of 2016 was $3.7 million or a loss of $0.08 per share, compared to GAAP net loss of $10,000, or $0.00 per share, for the first quarter of 2015.

Non-GAAP net loss (which excludes stock compensation and normalizes tax expense) for the first quarter of 2016 was $2.1 million, or $0.04 loss per diluted share, compared to a net income of $0.4 million, or $0.01 earnings per diluted share, for the first quarter of 2015.

Total cash and cash equivalents and short-term investments increased by $0.2 million from year-end ending March 31, 2016 at $13.1 million.

Fully diluted weighted average common shares outstanding as of March 31, 2016 were 46.1 million, compared to 45.5 million fully diluted weighted average common shares outstanding as of March 31, 2015.

The Company uses a non-GAAP reconciliation of gross profit, income (loss) before taxes, net income (loss) and earnings (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 is excluded from the non-GAAP earnings calculation and adjustments are made for Proforma taxes. Since we are in a cumulative loss position, the non-GAAP income tax expense (benefit) for the fiscal year 2016 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.
