<font> <font> O2Micro Expects Upside Q2 Results </font>
<font> Monday, June 15, 2009 8:30:01 AM ET </font> </font>
<font> O2Micro(R) International Limited (NASDAQ(R):OIIM) (SEHK:0457), a leading supplier of innovative power management and security components, expects Q2 2009 results to exceed prior expectations. </font>
<font> The company estimates that Q2 2009 revenue should be approximately $34 million. At this level, Q2 revenue would represent a sequential increase of approximately 47% from the first quarter of 2009. The corresponding gross margin should be at the upper-end of the company’s original range for the second quarter, while operating expenses should also be consistent with the original Q2 targets. </font>
<font> The strength in the second quarter of 2009 was attributable to resilient demand in the LCD TV market, the continued ramp of new products, and growth in the Chinese market, in addition to other contributors. </font>
<font> Sterling Du, Chairman and CEO, commented, "We are seeing follow through from many of the same factors that contributed to our upside surprise in the first quarter. These factors are validating our long-term investments in China and new products, as well as helping us to overcome challenging business conditions." </font>
