STATS ChipPAC Reports Second Quarter 2007 Results

United States — 7/25/2007, Singapore — 7/26/2007 — STATS ChipPAC Ltd. (“STATS ChipPAC” or the “Company” — NASDAQ: STTS and SGX-ST: STATSChP), a leading independent semiconductor test and advanced packaging service provider, today announced results for the second quarter 2007.

Tan Lay Koon, President and Chief Executive Officer of STATS ChipPAC said, “Our second quarter was impacted by weak demand from certain large customers. As a result, our revenue declined about 5.2% from prior quarter. In general, we saw strong growth in our consumer and multi-applications market in applications like NAND flash, portable multimedia devices, digital TV and camera. Wireless communications were generally strong. Our personal computer business was weaker but improved towards the end of the second quarter on recovery of storage devices and graphics chipsets.”

Revenue for the second quarter of 2007 decreased 11.5% to $370.2 million, compared to $418.1 million in the second quarter of 2006. This represents a sequential decline of 5.2% compared to the first quarter of 2007. Net income for the second quarter of 2007 was $7.4 million or $0.04 per diluted ADS, compared to net income of $18.0 million or $0.09 per diluted ADS in the second quarter of 2006. Net income for the second quarter of 2007 included approximately $2.0 million in share-based compensation expense as required under SFAS 123(R), $4.1 million in non-recurring expenses related to the tender offer from Singapore Technologies Semiconductors Pte Ltd, a wholly-owned subsidiary of Temasek Holdings (Private) Limited, $1.7 million in impairment on the Company’s assets used to manufacture discrete power packages that are classified as held for sale and $1.0 million in restructuring expenses.

Tham Kah Locke, acting Chief Financial Officer of STATS ChipPAC said, “We continue to focus our capital spending on strategic customer programs and to emphasize the generation of cash flow from our operations. In the second quarter of 2007, we spent approximately $55.4 million in capital expenditures, which was 15.0% of revenue compared to 26.9% of revenue in the second quarter of 2006. Gross margin in this quarter was 18.1% compared to 19.9% in prior quarter. The margin declined due to lower revenue.”

Outlook
Tan Lay Koon, commented, “For the third quarter, we expect revenue to be approximately in the range of $389.0 million to $408.0 million or in the range of 5% to 10% higher than the second quarter of 2007, with US GAAP net income in the range of $18.0 million to $24.0 million, which represents US GAAP net income per diluted ADS of $0.08 to $0.11, including the impact of approximately $0.01 per diluted ADS for the expensing of share-based compensation.”
