Monolithic Power Systems Announces Record Third Quarter Revenue and Net Income Results

SAN JOSE, Calif., Oct. 23 /PRNewswire-FirstCall/ -- Monolithic Power Systems (MPS) (Nasdaq: MPWR), a leading fabless manufacturer of high- performance analog and mixed-signal semiconductors, today announced financial results for the three and nine months ended September 30, 2008.

The results for the quarter ended September 30, 2008 are as follows:

The results for the nine months ended September 30, 2008 are as follows:

"MPS saw very strong results this quarter, particularly in our DC to DC product segment," said Michael Hsing, chief executive officer and founder of MPS. "We are well-positioned to continue to capture opportunities in this market with our tremendous slate of new products. As our revenue approached $50M this quarter, MPS is becoming a major player in the Power Management segment of the analog semiconductor market."

"While MPS has been doing well and we continue to deliver innovative products, we recognize that the last few weeks have seen a deterioration in general demand for electronic products, as a result of the worldwide financial crisis and associated macro-economic slowdown. Despite excellent execution, MPS is affected by the current economic crisis. For the fourth quarter of 2008, our normal seasonality in the consumer segment typically means that the fourth quarter is somewhat down sequentially from the third quarter. We have noticed some cancelations and delays in new projects. On the other hand, we also see many of our new products starting to ramp up to volume production. Therefore, our fourth quarter revenue is very uncertain compared with prior years. Our fourth quarter revenue guidance is in a wider range of 39 to 43 million dollars," said Mr. Hsing.

Business Outlook

The following are MPS' financial targets for the fourth quarter ending December 31, 2008:

(1) Non-GAAP net income, non-GAAP operating expenses and non-GAAP research and development and selling, general and administrative expense differ from net income, operating expenses, and research and development and selling, general and administrative expense determined in accordance with GAAP (Generally Accepted Accounting Principles in the United States). Non-GAAP net income for the quarter and nine months ended September 30, 2008 and 2007 excludes the effect of stock-based compensation expense and a patent litigation settlement amount and their related tax effects. Non-GAAP operating expenses for the quarter and nine months ended September 30, 2008 and 2007 exclude the effect of stock-based compensation expense and a patent litigation settlement amount, and include a reversal of our lease write-off that was recorded previously. Projected non-GAAP research and development and selling, general and administrative expenses exclude the effect of stock-based compensation expense and related tax effects. A schedule reconciling these amounts is included in this news release. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. MPS utilizes both GAAP and non- GAAP financial measures to assess what it believes to be its core operating performance and to evaluate and manage its internal business and assist in making financial operating decisions. MPS believes that the inclusion of non- GAAP financial measures, together with GAAP measures, provides investors with an alternative presentation useful to investors' understanding of MPS' core operating results and trends. Additionally, MPS believes that the inclusion of non-GAAP measures, together with GAAP measures, provides investors with an additional dimension of comparability to similar companies. However, investors should be aware that non-GAAP financial measures utilized by other companies are not likely to be comparable in most cases to the non-GAAP financials measures used by MPS.
