Financial Summary

Consolidated revenue in the first quarter of 2019 increased 41% to $10.1 million from $7.1 million in the same year-ago quarter. The increase was primarily driven by revenue from acquisitions, which contributed $4.8 million in the quarter, partially offset by a decrease in revenue on an organic basis and dissolution of SkyScale.



Revenue for the first quarter was lower than expected due to the delay of shipments for two purchase orders totaling $3.2 million. One delayed shipment was for military flash array products, which was delayed due to customer-requested postponement of the shipment. These products were subsequently shipped in April.

The second delayed shipment was for in-flight entertainment systems, which was delayed due to late-arriving materials that did not meet specifications. The issues that delayed this second shipment have also been resolved, and these products are expected to ship later this month.

These delays effectively shifted revenue from the first to the second quarter. The revenue delays for these two shipments were offset by about $1 million in shipments to other customers that exceeded expectations.

Revenue on an organic basis, which excludes 2018 acquisitions, decreased 27% to $5.2 million in Q1, due to the delayed shipment for flash array products.

Bressner, acquired in October 2018, contributed $4.5 million or 45% of consolidated revenue in Q1. CDI, acquired in August 2018, contributed $300,000 or 3% of the consolidated revenue in Q1.

Gross profit was $2.4 million or 24% of net revenue, compared to $2.2 million or 31% of net revenue in the same year-ago quarter. The decrease in gross margin percentage is due to lower sales of flash array products and in-flight entertainment systems attributed to the shipment delays, and lower margins from Bressner due to a certain bulk sale.

Total operating expenses increased 52% to $4.4 million from $2.9 million in first quarter 2018. The increase was due to expenses associated with being a public company, and increased expenses associated with CDI and Bressner.

Net loss attributable to common stockholders on a GAAP basis totaled $945,000 or $(0.07) per share in Q1 compared to $794,000 or $(0.08) per share in the year-ago period.

Net loss attributable to common stockholders on a non-GAAP basis totaled $418,000 or $(0.03) per share in Q1, as compared to $660,000 or $(0.07) per share in the same year-ago period.

Adjusted EBITDA, a non-GAAP term, was a loss of $1.4 million in Q1, as compared to a loss of $237,000 in the same year-ago period. See definitions of these non-GAAP terms and reconciliation to GAAP, below.

Cash and cash equivalents totaled $455,000 at March 31, 2019, as compared to $2.3 million at December 31, 2018. The decrease is primarily due to cash used to pay down Bressner subsidiary debt, as well as for working capital and infrastructure investments.

To provide for future liquidity, during the first quarter, certain members of the company’s board of directors agreed to funding commitments of up to $4.0 million. In addition, the Bressner subsidiary entered into a new line of credit for up to €2 million.

Subsequent to the quarter-end, the company borrowed $1.5 million of the $4.0 million commitment from multiple parties, inclusive of members of the board of directors. Bressner also entered into a new term loan agreement for €500,000.

In 2019, the company is investing approximately $1.5 million in infrastructure projects to increase capacity, improve operating efficiencies and stay on the forefront of high-performance computing technologies. These investments include a major expansion and remodel of the company’s corporate headquarters and primary manufacturing facilities in Escondido, implementation of a new company-wide ERP system, and investment in new hardware and software tools relating to high bandwidth system design.



The company is developing plans for cost containment as well as debt and/or equity financing to ensure liquidity will be sufficient to meet cash requirements for operations for at least the next 12 months.

Management Commentary

“The delayed shipments for two key customers had a significant impact on our Q1 financial results,” said OSS president and CEO, Steve Cooper. “Now that the delays have been resolved, we are comfortable that these delays represent a short-term shift in revenue timing.

“Other than the shipping delays, it was a strong first quarter in many respects. We are encouraged that the broader segments of our business exceeded our expectations in Q1, that our major OEM customers are scaling up, and we are making significant progress toward winning new major OEM design-ins. Our technology and architectural leadership with PCIe Gen 4 and AI on the Fly, are resonating in the marketplace and providing increasing opportunities for new business.

“With the delayed order revenue expected to shift into Q2, we anticipate record revenue for the quarter, keeping us on track for our stated guidance range for the full fiscal year.”

Guidance Update

The company reiterates its outlook for the full year 2019: revenue is anticipated to be between $54 million and $58 million, representing organic growth of 12% to 18% and overall growth of 51% to 54%.

The company expects revenue for Q2-2019 (inclusive of revenue shift from Q1) to be in the range of $13.8 million to $15.0 million, representing growth of 134% to 155%, with organic growth of 54% to 68%, as compared to the same year-ago quarter. At the midpoint of the guidance, the revenue is expected to be approximately $9.6 million organically, with Bressner contributing $3.8 million and CDI adding $1.0 million.

Quarterly revenue may fluctuate plus or minus 15% from the company’s guidance in any given quarter due to variations in delivery schedules and/or seasonal fluctuations.

Non-GAAP Financial Measures

OSS management believes that the use of adjusted earnings before interest, taxes, depreciation and amortization, or adjusted EBITDA, is helpful for an investor to assess the performance of the company. The company defines adjusted EBITDA as income (loss) attributed to common stockholders before interest, taxes, depreciation, amortization, acquisition expense, finance cost, fair value adjustments from purchase accounting, stock-based compensation, and expenses related to discontinued operations.

Adjusted EBITDA is not a measurement of financial performance under generally accepted accounting principles in the United States, or GAAP. Because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact a company’s non-cash operating expenses, OSS management believes that providing a non-GAAP financial measure that excludes non-cash and non-recurring expenses allows for meaningful comparisons between the company’s core business operating results and those of other companies, as well as providing an important tool for financial and operational decision making and for evaluating our own core business operating results over different periods of time.



The company’s adjusted EBITDA measure may not provide information that is directly comparable to that provided by other companies in our industry, as other companies in its industry may calculate non-GAAP financial results differently, particularly related to non-recurring, unusual items. The company’s adjusted EBITDA is not a measurement of financial performance under GAAP, and should not be considered as an alternative to operating income or as an indication of operating performance or any other measure of performance derived in accordance with GAAP. OSS management does not consider adjusted EBITDA to be a substitute for, or superior to, the information provided by GAAP financial results.

Adjusted EPS excludes the impact of certain items and, therefore, has not been calculated in accordance with GAAP. Management believes that exclusion of certain selected items assists in providing a more complete understanding of its underlying results and trends and allows for comparability with the company’s peer company index and industry. Management uses this measure along with the corresponding GAAP financial measures to manage the company’s business and to evaluate its performance compared to prior periods and the marketplace. The company defines Non-GAAP (loss) income attributable to common stockholders as (loss) or income before amortization, stock-based compensation, expenses related to discontinued operations, acquisition expense. Adjusted EPS expresses adjusted (loss) income on a per share basis using weighted average diluted shares outstanding.

Adjusted EPS is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. These non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies. The company expects to continue to incur expenses similar to the adjusted income from continuing operations and adjusted EPS financial adjustments described above, and investors should not infer from the company’s presentation of these non-GAAP financial measures that these costs are unusual, infrequent or non-recurring.
