Financial Summary

Revenue in the first quarter of 2020 increased 33% to $13.4 million from $10.1 million in the sameyear-ago quarter. The increase was primarily driven by sales of custom servers to be used in media and entertainment, as well as PCIe Gen 4 products andAI on the Fly technology for autonomous driving vehicles. The company’s Bressner subsidiary contributed $4.9 million or 36.8% of consolidated first quarter revenue, while CDI contributed $622,000 or 4.6%.

Gross profit in the first quarter of 2020 was $3.4 million or 25.4% of revenue, compared to $2.4 million or 24.0% of revenue in the sameyear-ago quarter. Gross margin for the company’s core OSS business was down slightly to 28.1% in the first quarter of 2020 from 28.7% in the sameyear-ago quarter. Both Bressner and CDI gross margins improved, contributing 21.9% and 19.7%, respectively.

Total operating expenses increased 10.4% to $4.9 million from $4.4 million in first quarter 2019. The increase was primarily due to increased general and administrative (G&A) expense that was primarily attributable to the accrual of severance benefits, as well as increased marketing and selling expense, which was partially offset by a decrease in R&D expense.

Overall operating expenses decreased as a percentage of revenue to 36.7% in the first quarter of 2020, as compared to 44.2% in the sameyear-ago quarter. This expense level does not reflect the $2.5 million to $3.0

1

million in anticipated annual savings resulting from the company’s recently implemented expense reduction program. Excludingone-time severance cost, operating expenses would have been flat in the first quarter of 2020 compared to the sameyear-ago quarter.

Net loss attributable to common stockholders on a GAAP basis totaled $1.1 million or $(0.07) per share in Q1 compared to a loss of $945,000 or $(0.07) per share in theyear-ago period.

Non-GAAP net loss attributable to common stockholders totaled $714,000 or $(0.04) per share in Q1, as compared to $428,000 or $(0.03) per share in the sameyear-ago period.

Adjusted EBITDA, anon-GAAP term, was negative $950,000 in Q1, as compared to negative $1.4 million in the sameyear-ago period. (See the definitions of thesenon-GAAP terms and reconciliation to GAAP, below.)

Cash and cash equivalents totaled $3.0 million at March 31, 2020, as compared to $5.2 million at December 31, 2019. The decrease is primarily due to cash used in operations and financing activities.

Subsequent to the end of the quarter, the company raised $2.5 million in a convertible debt offering and also has received a Paycheck Protection Plan loan of approximately $1.5 million. Inclusive of these financing proceeds, the company currently has cash on hand of $5.0 million. The company believes its cash position and available funds provide it with sufficient liquidity to meet its cash requirements for the current operations.

Management Commentary

“Our strongtop-line growth in the first quarter, which exceeded our expectations, was driven by our expanded product offerings and strengthened sales capabilities,” said David Raun, OSS interim CEO. “We recently received $3.5 million in production orders for our new Gen 4 PCIe products from multiple OEM customers for delivery in 2020. These OEM orders represent highly desirable ‘sticky’ engagements, where our technology is built into their designs.

“The medical, military, and other critical applications served by our products, has required OSS to remain in operation and continue to provide the essential infrastructure products that we design and manufacture. While we have been impacted by COVID-19 like other companies, our teams acted swiftly in Q1 to secure supplies early and pivoted to a virtual workforce.

“During the quarter we closed three new program wins exceeding $1 million each. Two of the three wins are with new customers, one military and one industrial OEM. “As of today, we have 27 large opportunities in our pipeline. Eight of these involve our leadership in our PCI Express Gen 4 products.

“On the new product front, we are planning to introduce four new PCI Express Gen 4 platforms in 2020. We are seeing significant interest in these leading-edge standard products, and we expect to convert this interest into more Gen 4 revenue later this year.

“Over the past 90 days, the management team has been working to ensure sustainability while also laying a stronger foundation for future growth. Actions taking during this period include expense reductions, a reorganization and securing additional capital. While the objectives associated with most of these recently implemented changes will take time to yield the desired effect and propel the company to the next level, we expect the benefit from the expense reductions will start to show in the current quarter and be fully realized in the 2nd half of the year. We eliminated approximately $2.5 million to $3.0 million in annual spend.

Outlook

For the second quarter, unlike many companies who elected not to provide guidance, in the spirit of transparency, OSS is providing a minimum baseline for expected revenue of $10 million for Q2. Given the company’s strong first quarter of 2020, it expects revenue for the first half of the year to be at least on par with the first half of 2019. While OSS is diligently working multiple challenges in parallel to bring performance up above this baseline, the company wants to be realistic in terms of setting expectations given the market variables.

Although OSS’ large media & entertainment customer came close to forecast in Q1, their shipments in the current quarter are down significantly. The management teams from both companies are in constant contact and it appears the customer’s product offering is well positioned to capitalize on the market return.

In addition, OSS has been impacted by supply chain issues, especially for high-end PCB boards, that affect multiple customer orders. Fortunately, other than these dynamics, customers want OSS products and demand remains solid.

Consistent with prior years, the company expects a stronger second half of the year in terms of revenue and margin performance. While the impact of the coronavirus continues to create uncertainties, the programs that are expected to drive higher revenue and margins remain currently on track.

Non-GAAP Financial Measures

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) attributable to common stockholders before interest, taxes, depreciation, amortization, acquisition expenses, impairment of long-lived assets, financing costs, fair value adjustments from purchase accounting, stock-based compensation expense 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’snon-cash operating expenses, OSS management believes that providing anon-GAAP financial measure that excludesnon-cash andnon-recurring expenses allows for meaningful comparisons between the company’s core business

operating results and those of other companies, as well as providing the company with an important tool for financial and operational decision making and for evaluating its 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 its industry, as other companies in its industry may calculatenon-GAAP financial results differently, particularly related tonon-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 EBITDA	$	(949,556	)	$	(1,423,782	)

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

Adjusted EPS is anon-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. Thesenon-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 thesenon-GAAP financial measures that these costs are unusual, infrequent ornon-recurring.
