Financial report summary

  • Our failure to raise additional capital or generate the significant capital necessary to expand our operations and invest in new products could reduce our ability to compete and could harm our business.
  • Our future success is substantially dependent on the successful development of our Virtual Accelerator Engine IP product line, which entails significant risks.
  • Our failure to successfully market our products could seriously harm our ability to execute our business strategy and may force us to curtail our research and development plans or existing operations.
  • Future revenue growth depends on our winning designs with existing and new customers, retaining current customers, and having those customers design our solutions into their product offerings and successfully selling and marketing such products. If we do not continue to win designs in the short term, our product revenue in the following years will not grow.
  • The IC design win process is generally a lengthy, expensive and competitive process, with no guarantee of revenue, and, if we fail to generate sufficient revenue to offset our expenses, our business and operating results would suffer.
  • If our foundry does not achieve satisfactory yields or quality, our cost of net revenue will increase, our operating margins will decline and our reputation and customer relationships could be harmed.
  • We may experience difficulties in transitioning to new wafer fabrication process technologies or in achieving higher levels of design integration, which may result in reduced manufacturing yields, delays in product deliveries and increased costs.
  • To date, we have not achieved the anticipated benefits of a fabless semiconductor company.
  • Our main objective is the development and sale of our technologies to cloud networking, security, test and video system providers and their subsystem and component vendors and, if demand for these products does not grow, we may not achieve revenue growth and our strategic objectives.
  • Our failure to continue to develop new products and enhance our products on a timely basis could diminish our ability to attract and retain customers.
  • Our ICs have a lengthy sales cycle, which makes it difficult to predict success in this market and the timing of future revenue.
  • The semiconductor industry is cyclical in nature and subject to periodic downturns, which can negatively affect our revenue.
  • We expect our 1T-SRAM royalty revenues to decrease compared with our historical results, and there is no guarantee revenues from our IC products will replace these lost revenues in the near future.
  • Our revenue has been highly concentrated among a small number of customers, and our results of operations could be harmed if we lose a key revenue source and fail to replace it.
  • Our revenue concentration may also pose credit risks which could negatively affect our cash flow and financial condition.
  • Our products must meet exact specifications and defects and failures may occur, which may cause customers to return or stop buying our products.
  • Because we sell our IC products on a purchase order basis and rely on estimated forecasts of our customers’ needs, inaccurate forecasts could adversely affect our business.
  • We depend on contract manufacturers for a significant portion of our revenue from the sale of our IC products.
  • We rely on an independent foundry and contractors for the manufacture, assembly, testing and packaging of our integrated circuits, and the failure of any of these third parties to deliver products or otherwise perform as requested could damage our relationships with our customers and harm our sales and financial results.
  • Any claim that our products or technology infringe third party IP rights could increase our costs of operation and distract management and could result in expensive settlement costs or the discontinuance of our technology licensing or product offerings. In addition, we may incur substantial litigation expense which would adversely affect our profitability.
  • The discovery of defects in our technology and products could expose us to liability for damages.
  • Royalty amounts owed to us might be difficult to verify, and we might find it difficult, expensive and time-consuming to enforce our license agreements.
  • We might not be able to protect and enforce our IP rights which could impair our ability to compete and reduce the value of our technology.
  • Our existing patents might not provide us with sufficient protection of our IP, and our patent applications might not result in the issuance of patents, either of which could reduce the value of our core technology and harm our business.
  • If we fail to retain key personnel, our business and growth could be negatively affected.
  • We may incur additional debt in the future.
  • Our ability to utilize our net operating loss carryforwards may be limited as a result of an “ownership change,” as defined in Section 382 of the Internal Revenue Code of 1986, as amended.
  • Acquisitions or other business combinations that we pursue in the future, whether or not consummated, could result in other operating and financial difficulties.
  • Provisions of our certificate of incorporation and bylaws or Delaware law might delay or prevent a change-of-control transaction and depress the market price of our stock.
  • Potential volatility of the price of our common stock could negatively affect your investment.
  • We are a “smaller reporting company” and, as a result of the reduced disclosure and governance requirements applicable to smaller reporting companies, our common stock may be less attractive to investors.
  • If we fail to maintain compliance with the continued listing requirements of the Nasdaq Stock Market, our common stock may be delisted and the price of our common stock and our ability to access the capital markets could be negatively impacted.
Management Discussion
  • Product revenue increased for the three months ended March 31, 2021 compared with the same period of 2020 primarily due to higher sales of our Bandwidth Engine 2 products, partially offset by decreases in our LineSpeed product sales.
  • Royalty and other includes license, royalty and related revenues generated from licensing agreements. The decrease in royalty and other revenue for the three months ended March 31, 2021 compared with the same period of 2020 was primarily due to a decrease in royalty revenue for one licensee.
  • Cost of net revenue is primarily comprised of direct and indirect costs related to the sale of our IC products.
