• Net cash flow from operations decreased to $35.8 million in 1Q12 from $84.7 million in 4Q11 mainly due to VAT refund in 2011 Q4.
• Loss attributable to Semiconductor Manufacturing International Corporation was $ 42.8 million in 1Q12, compared to loss of $165.2 million in 4Q11.

Second Quarter 2012 Guidance:

The following statements are forward looking statements which are based on current expectations and which involve risks and uncertainties, some of which are set forth under "Safe Harbor Statements" below.

• Revenue is expected to increase between 19% and 21%.
• Gross margin is expected to range from 19% to 22%.
• Operating expenses excluding foreign exchange differences are expected to range from $101 million to $104 million.

Dr. Tzu-Yin Chiu, Chief Executive Officer, commented, "In the first quarter of 2012, our revenue grew 15% sequentially; in the second quarter of 2012, our revenue is guided to increase between 19 and 21%; and into the second half of this year, we target continued growth. This ongoing momentum is primarily due to various new product ramp-ups for connectivity chips, mobile phones and set-top boxes, and is also attributable to increased demand for some of our existing products. Apart from macro reasons, the increase in demand and utilization is also driven by performance improvements."

"Our China revenue continues to grow along with China's semiconductor market. In the first quarter of 2012, our China revenue grew 9.5% quarter over quarter, equivalent to about 32.5% of our total revenue in the first quarter of 2012."

"We have successfully obtained two major loans in the first quarter of 2012. First, we obtained a $268 million loan facility in February, and second, a $600 million syndicated loan in March. These credit arrangements have helped us achieve a healthier capital structure, and show that both policy and commercial banks recognize our potential."

"We are excited about the growth prospects of the coming quarters and are expecting continued order momentum for both new and existing products, across various applications, from our leading global and Chinese customers."
