MONOLITHIC POWER SYSTEMS INC Quarterly Report for Q1 Ended Mar 31, 2008

Filed May 14, 2008For Securities:MPWR

Summary

Monolithic Power Systems, Inc. (MPWR) reported a significant revenue increase of 44.6% to $35.4 million for the three months ended March 31, 2008, compared to $24.5 million in the prior year period. This growth was primarily driven by strong sales in DC to DC converters and improved performance in LCD backlight inverters and audio amplifiers. The company achieved profitability in the current quarter, reporting a net income of $5.9 million, a substantial turnaround from a net loss of $0.3 million in the same period of 2007, which was partly impacted by a prior period restatement. Despite strong top-line growth and improved profitability, the company faces ongoing litigation risks, particularly with O2 Micro, Inc., and a concerning illiquidity in its auction-rate securities portfolio. Management believes existing cash and cash equivalents will be sufficient for the next 12 months, but the company's exposure to litigation and market risks remains a key consideration for investors.

Frequently Asked Questions

The company reported a 44.6% increase in revenue to $35.4 million, primarily driven by a 51.6% increase in sales of DC to DC converters due to strong demand in flat panel TVs and consumer devices. Sales of LCD backlight inverters also increased by 19.7%, and audio amplifiers saw a 63.8% rise due to demand in consumer electronics.

As of March 31, 2008, MPWR had $64.3 million in cash and cash equivalents and $4.8 million in short-term investments. The company generated $5.9 million in operating cash flow for the quarter. Management believes that cash generated from operations and existing balances will be sufficient to meet liquidity requirements for the next 12 months. However, a significant portion of its investment portfolio, $39.1 million, is in illiquid auction-rate securities, posing a potential liquidity risk.

The company faces significant ongoing patent litigation with O2 Micro, Inc., with appeals pending and new claims filed, which could materially impact its ability to sell products or result in substantial damages. Additionally, a material weakness in internal controls related to the tax effects of stock-based compensation was identified, leading to a restatement of prior financial statements and ongoing remedial efforts. The illiquidity of auction-rate securities also presents a market risk.
