Summary

Monolithic Power Systems, Inc. (MPWR) filed its 2006 annual report on Form 10-K, revealing a year of modest revenue growth and a net loss. Total revenue reached $105 million, a 5.9% increase from the prior year, driven primarily by DC to DC converter sales, though offset by a significant decline in LCD backlight inverter revenue. The company continues to invest heavily in research and development, with R&D expenses increasing by 50.4% to $22.3 million. Significant litigation expenses related to patent infringement cases, particularly with O2 Micro, continue to impact profitability, contributing to a net loss of $2.86 million for the year. The company operates in the competitive analog and mixed-signal semiconductor market, focusing on high integration and efficiency. While diversification of its customer base is noted, a substantial portion of revenue still comes from a few key customers. MPWR maintains a fabless business model, relying on third-party manufacturers, and has expanded its operations in China for testing and manufacturing support. The company is managing its liquidity well but faces ongoing risks from litigation, product development, and intense market competition.
