The complaint charges SemiLEDs and certain of its officers with violations of the Securities Exchange Act of 1934. SemiLEDs is a holding company for its wholly-and majority-owned subsidiaries and joint ventures that collectively develop, manufacture and sell high performance light emitting diode (“LED”) chips and components that are used primarily in general lighting applications, including street lights and commercial, industrial and residential lighting. The complaint alleges that during the Class Period, defendants issued materially false and misleading statements regarding the Company’s operations and business. Specifically, defendants failed to disclose: (i) that the Company was experiencing known, but undisclosed, pricing pressures for its products which were reasonably likely to have a material adverse effect on SemiLEDs’ future revenues and operating income; (ii) that known events or uncertainties, including the reduction in demand for the Company’s products, the likely (and ultimate) loss of a large customer, and the decline in the value of the Company’s inventory, were reasonably likely to cause SemiLED’s financial information not to be indicative of future operating results; (iii) that the Company’s disclosure controls were materially deficient and its representations concerning them were materially false and misleading; (iv) that the certifications issued by defendants associated with the Company’s disclosure controls were materially false and misleading; and (v) that, based on the foregoing, defendants lacked a reasonable basis for their positive statements about the Company, and its then current business and future financial prospects.
