Monolithic Power Systems Announces First Quarter 2009 Results

SAN JOSE, Calif., April 28, 2009 /PRNewswire-FirstCall via COMTEX/ -- Monolithic Power Systems (MPS) (Nasdaq: MPWR), a leading fabless manufacturer of high-performance analog and mixed-signal semiconductors, today announced financial results for the quarter ended March 31, 2009.

The results for the quarter ended March 31, 2009 are as follows:

"In the second half of the quarter, we saw increased turns activities. As a result, our Q1 revenue was better than we expected," said Michael Hsing, chief executive officer and founder of MPS. "We are still cautiously optimistic about the next quarter. However, MPS is always ready for fast changing environments either in up or down markets. The last two quarters proved that. Despite a significant reduction in product demand, MPS will continue to focus on generating cash and delivering profits."

Business Outlook

The following are MPS' financial targets for the second quarter ending June 30, 2009:

(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 ended March 31, 2009 and 2008 excludes the effect of stock-based compensation expense and their related tax effects. Non-GAAP operating expenses for the quarter ended March 31, 2009 and 2008 exclude the effect of stock-based compensation expense. Projected non-GAAP research and development and selling, general and administrative expenses exclude the effect of stock-based compensation expense. 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.
