CORPORATE RELEASE

STATS ChipPAC Ltd. Updates Announcement
of 16 May 2007

United States — 5/17/2007, Singapore — 5/18/2007 — STATS ChipPAC Ltd. (“STATS ChipPAC” or the “Company” — NASDAQ: STTS and SGX-ST: STATSChP), a leading independent semiconductor test and advanced packaging service provider, refers to the voluntary conditional cash offer (Offer) announced on 1 March, 2007 by Goldman Sachs (Singapore) Pte (Goldman Sachs), for and on behalf of Singapore Technologies Semiconductors Pte Ltd (Offeror) and to the Company’s announcement on 16 May 2007 (16 May Announcement).

In the 16 May Announcement, the Company announced that it had received notification from Marathon Asset Management LLP (Marathon) and Oz Management LLC (Oz) of their interest in the Company’s Ordinary Shares and that taking into account the interest held by Marathon and Oz and the approximate shareholding of the Offeror, less than 10% of its Ordinary Shares may be held in public hands and therefore under Rule 724 of the Singapore Exchange Securities Trading Limited (SGX-ST) Listing Manual, SGX-ST may suspend trading of the Company’s Ordinary Shares if less than 10% of its issued Ordinary Shares are held in public hands, as required by Rule 723 of the SGX-ST Listing Manual.

On 17 May 2007, the Company became aware that Oz has ceased to be a substantial shareholder of the Company and based on the information set out in the notification from Oz (Subsequent Oz Notification), Oz holds 1.87% of the issued Ordinary Shares (including ADSs) of the Company. A copy of the Subsequent Oz Notification is attached.

On 17 May 2007 based on information set out in a notification from Marathon (Subsequent Marathon Notification), the Company also became aware that Marathon has voting control over 5.02% of the issued Ordinary Shares causing Marathon to be a substantial shareholder of the Company. The Subsequent Marathon Notification also states that Marathon has dispositive but non-voting authority over an additional 1.84% of the issued Ordinary Shares of the Company. A copy of the Subsequent Marathon Notification is attached.

Taking into account the Subsequent Oz Notification and the Subsequent Marathon Notification, as at the date of this Announcement as far as the Company is aware, it has no reason to believe that less than 10% of the Company’s issued Ordinary Shares are in the hands of the public.
