Smith Micro Reports Third Quarter 2018 Financial Results

Company Achieves Non-GAAP Profitability During the Quarter

ALISO VIEJO, CA, October 24, 2018 – Smith Micro Software, Inc. (NASDAQ: SMSI), today reported financial results for its third quarter ended September 30, 2018.

“I am overall pleased with the quarter that came in line with our expectations,” said William W. Smith Jr., President and CEO of Smith Micro Software. “Revenues increased over the prior year, and we again achieved operating profitability during the quarter.”

“During the first nine months of this fiscal year, we have made tremendous strides throughout the organization, particularly with the product enhancements that we plan to launch in the fourth quarter. We remain focused on optimizing performance and driving revenue on our core product platforms, SafePath® and CommSuite®, so that we can finish the year strong and maximize 2019 opportunities.”

Fiscal Third Quarter 2018 Financial Results:

Smith Micro Software reported revenue of $6.5 million for the third quarter ended September 30, 2018, compared to $5.8 million reported in the third quarter ended September 30, 2017.

Third quarter 2018 gross profit was $5.5 million, compared to $4.6 million reported in the third quarter of 2017.

Gross profit as a percentage of revenue was 85 percent for the third quarter of 2018, compared to 80 percent for the third quarter of 2017.

Generally accepted accounting principles in the United States (“GAAP”) net loss available to common stockholders for the third quarter of 2018 was $1.0 million, or $0.04 loss per share, compared to a GAAP net loss available to common stockholders of $1.7 million, or $0.12 loss per share, for the third quarter of 2017.

Non-GAAP net income (which excludes non-cash stock-based compensation, amortization of intangibles, debt issuance and discount costs, fair value adjustments, loss on debt extinguishment, preferred stock dividends, and a normalized tax expense) for the third quarter of 2018 was $0.2 million, or $0.01 per share, compared to a non-GAAP net loss of $0.6 million, or $0.04 loss per share, for the third quarter of 2017.

Fiscal September Year-to-Date 2018 Financial Results:

Smith Micro Software reported revenue of $18.9 million for the nine months ended September 30, 2018, compared to $17.2 million reported for the nine months ended September 30, 2017.

Gross profit for the nine months ended September 30, 2018 was $15.5 million, compared to $13.5 million reported for the same period in 2017.

Gross profit as a percentage of revenue was 82 percent for the nine months ended September 30, 2018, compared to 78 percent for the nine months ended September 30, 2017.

GAAP net loss available to common stockholders for the nine months ended September 30, 2018 was $5.9 million, or $0.28 loss per share, compared to a GAAP net loss available to common stockholders of $6.5 million, or $0.49 loss per share, for the same period in 2017.

Non-GAAP net loss (which excludes non-cash stock-based compensation, amortization of intangibles, debt issuance and discount costs, fair value adjustments, loss on debt extinguishment, preferred stock dividends, and a normalized tax benefit) for the nine months ended September 30, 2018 was $1.0 million, or $0.05 loss per share, compared to a non-GAAP net loss of $2.8 million, or $0.21 loss per share, for the nine months ended September 30, 2017.

Total cash and cash equivalents at September 30, 2018 were $8.4 million.

To supplement our financial information presented in accordance with GAAP, the Company considers and has included in this press release certain non-GAAP financial measures, including a non-GAAP

reconciliation of gross profit, income (loss) before taxes, net income (loss) available to common stockholders, and earnings (loss) per share in the presentation of financial results in this press release. Management believes this non-GAAP presentation may be more meaningful in analyzing our income generation and therefore has excluded the following non-cash items from GAAP earnings calculations: stock-based compensation, amortization of intangible assets, debt issuance and discount costs, fair value adjustments, and preferred stock dividends. Additionally, since we are in a cumulative loss position, a non-GAAP income tax expense (benefit) was computed using a 24 percent and 38 percent tax rate for 2018 and 2017, respectively, 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 table below presents the differences between non-GAAP net income (loss) 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.
