("STT Comm") with the Securities and Exchange Commission on October 11, 2002, as amended and restated by Amendment No. 1 to Schedule 13D filed on January 3, 2003 by STT Comm and as further amended by Amendment No. 2 to Schedule 13D filed on December 22, 2003 by STT Comm (as amended, the "Statement") with respect to the common stock, par value $0.001 per share (the "Common Stock") of Equinix, Inc., a Delaware corporation (the "Issuer"). Capitalized terms used but not defined herein have the meanings given to them in the Statement. ITEM 2. IDENTITY AND BACKGROUND Schedule A, which contains information regarding the executive officers and directors of the Reporting Persons, is amended and restated in its entirety. In connection with an internal restructuring to be effected on December 31, 2004, the shares of STT presently owned by Singapore Technologies Pte Ltd ("STPL") will be transferred to Temasek Holdings (Private) Limited ("Temasek"). Item 2 and Schedule A of the Statement are hereby amended to delete all references to STPL with effect from December 31, 2004. Accordingly, STPL will cease to be a Reporting Person with effect from December 31, 2004. ITEM 4. PURPOSE OF TRANSACTION Item 4 is hereby amended to add the following: i-STT Investments Pte Ltd ("i-STTI") is a direct, wholly-owned subsidiary of STT Comm. On December 30, 2004, Temasek, through its indirect subsidiary STT Comm, filed a Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), to facilitate the acquisition by i-STTI from time to time in the open market or otherwise of shares of Common Stock and/or other voting securities of the Issuer, including shares of Common Stock issuable upon conversion of the shares of Preferred Stock (including Preferred Stock acquired upon exercise of the Warrants), the Notes and the PIK Notes owned by i-STTI (the "Derivative Securities"), which when added to the shares of Common Stock already owned could exceed 50 percent of the voting securities of the Issuer outstanding. Pursuant to the HSR Act, such acquisitions may be made by the Reporting Persons within 12 months of the expiration of the applicable waiting period, without filing a further Notification and Report Form. The waiting period is expected to expire on January 31, 2005. While none of the Reporting Persons have any plans to acquire any additional shares of Common Stock and/or other voting securities of the Issuer, except additional shares of Common Stock issuable upon conversion of certain of the Derivative Securities, the Reporting Persons could in the future determine to acquire additional shares of Common Stock and/or other voting securities of the Issuer in the open market or otherwise, including through exercise and/or conversion of the Derivative Securities, depending upon price, market conditions, availability of funds, evaluation of alternative investments and other factors. These additional acquisitions could result in the Reporting Persons beneficially owning more than 50 percent of the voting securities of the Issuer outstanding. Moreover, while none of the Reporting Persons have any present plans to dispose of any of the shares of Common Stock and/or other voting securities of the Issuer held by them, they could in the future determine, based upon the same set of factors above with respect to acquisitions, to dispose of some or all of the shares of Common Stock and/or other voting securities of the Issuer held by them. Page 8 of 17 Pages ITEM 5. INTEREST IN SECURITIES OF THE ISSUER Item 5 is amended and restated in its entirety as follows: On May 1, 2004, i-STTI received US$2,351,860 of Payment-In-Kind Notes ("PIK Notes") from the Issuer, which are convertible into 256,254 shares of Common Stock. On November 1, 2004, i-STTI received US$2,516,490 of PIK Notes from the Issuer, which are convertible into 274,191 shares of Common Stock. i-STTI owns beneficially and of record 9,995,964 shares of Common Stock, representing 39.2% of the outstanding shares of Common Stock. The shares include 1,084,686 shares of Common Stock acquired on December 31, 2002, 1,885,728 shares of Common Stock acquired on November 21, 2003, 1,868,667 shares of Common Stock that may be acquired upon conversion of the Preferred Stock owned of record by i-STTI, 3,268,734 shares of Common Stock that may be acquired upon conversion of the Notes owned of record by i-STTI, 922,475 shares of Common Stock that may be acquired upon conversion of the PIK Notes owned of record by i-STTI, and 965,674 shares of Common Stock that may be acquired upon the conversion of the Preferred Stock acquired upon the exercise of the Warrants owned of record by i-STTI. Because of the relationships described in Item 2 above, the Singapore Parent Entities may be deemed to beneficially own the shares owned of record by i-STTI. Temasek disclaims beneficial ownership of the shares owned beneficially and of record by i-STTI. In addition to the share amounts detailed in the preceding paragraph, Temasek may be deemed to beneficially own 11,718 additional shares of Common Stock, representing 0.05% of the outstanding Common Stock. The additional 11,718 shares of Common Stock are owned beneficially and of record by Temasek's indirect, wholly-owned subsidiary, T.H.e Venture Pte Ltd. The calculation of the percentages in the foregoing paragraphs is based on the number of shares of Common Stock disclosed as outstanding as of September 30, 2004 (i.e. 18,459,337 shares of Common Stock), in the Form 10-Q filed by the Issuer on November 4, 2004. Except as set forth in this Statement, to the knowledge of the Reporting Persons, no director or executive officer of any of the Reporting Persons beneficially owns any other securities of the Issuer. In connection with an internal restructuring to be effected on December 31, 2004, the shares of STT presently owned by STPL will be transferred to Temasek with effect from December 31, 2004. Item 5 of the Statement is hereby amended to delete all references to STPL with effect from December 31, 2004. Except as described in this Statement, there have been no transactions by the Reporting Persons in securities of the Issuer during the past sixty days. To the knowledge of the Reporting Persons, there have been no transactions by any director or executive officer of any of the Reporting Persons in securities of the Issuer during the past sixty days. Page 9 of 17 Pages After reasonable inquiry and to the best of its knowledge and belief, the undersigned certifies that the information set forth in this statement is true, complete and correct.
