We are offering€750,000,000 in aggregate principal amount of    % Senior Notes due 2024 (the “notes”). The notes will mature on March 15, 2024, unless earlier redeemed or repurchased.

We may redeem all or a part of the notes on or after September 15, 2020 on any one or more occasions, at the redemption prices set forth under “Description of Notes—Redemption,” plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date. In addition, at any time prior to September 15, 2020, we may on any one or more occasions redeem up to 35% of the aggregate principal amount of the notes outstanding under the supplemental indenture with the net cash proceeds of one or more equity offerings. At any time prior to September 15, 2020, we may also redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of notes redeemed plus a “make-whole” premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption.

The notes will be our general senior obligations and will rank equal in right of payment to all of our existing and future senior indebtedness. Upon a change in control triggering event, we will be required to make an offer to purchase each holder’s notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of purchase.

The notes will not be guaranteed by any of our subsidiaries. The obligations to make payments of principal and interest on the notes are solely our obligations. Therefore, the notes will be structurally subordinated to any obligation of our subsidiaries that are not guarantors.

We will apply, following the completion of this offering, to The International Stock Exchange Authority Limited (formerly known as The Channel Islands Securities Exchange Authority Limited) to have the notes listed on The International Stock Exchange and admitted for trading on the Official List of the Exchange on or prior to the first interest payment date. However, no assurance can be given that the notes will become or will remain listed. If such listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time.

We intend to use the net proceeds of this offering for general corporate purposes, which may include capital expenditures and working capital, and for potential acquisitions and strategic transactions. See “Use of Proceeds”.

PRIIPs Regulation; Prohibition of Sales to EEA Retail Investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the European Economic Area has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the European Economic Area may be unlawful under the PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of notes in any Member State of the European Economic Area will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes. This

S-2

prospectus supplement is not a prospectus for the purposes of the Prospectus Directive.

MiFID II Product Governance

Solely for the purposes of the product approval process of Barclays Bank plc, HSBC Securities (USA) Inc. and ING Bank N.V., London Branch (collectively, the “Manufacturers”), the target market assessment in respect of the notes has led to the conclusion that: (i) the target market for the notes is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the notes (a “distributor”) should take into consideration the Manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the notes (by either adopting or refining the Manufacturers’ target market assessment) and determining appropriate distribution channels.

Recent Developments

Proposed Acquisition of the Metronode Group

On December 15, 2017, through our wholly owned subsidiary, Equinix Australia Pty Limited (“Equinix Australia”), we entered into a sale and purchase of securities agreement (the “Transaction Agreement”) with Ontario Teachers’ Pension Plan Board (“OTPP”), pursuant to which, subject to certain conditions, we agreed, on the terms set forth in the Transaction Agreement, to acquire the entire equity interests held by OTPP and other vendors identified in the Transaction Agreement (collectively, the “Sellers”) in the Metronode group of companies

S-6

(the “Metronode Group”), for a cash purchase price of A$1.035 billion (approximately US$792 million) subject to certain adjustments described in the Transaction Agreement (the “Transaction”). The Metronode Group owns and operates 10 data centers in Australia spanning Adelaide, Brisbane, Canberra, Melbourne, Perth and Sydney in Australia (the “Acquired Data Centers”). As part of the Transaction, through the acquisition of the Metronode Group, Equinix Australia will also acquire freehold and leasehold real estate interests at the Acquired Data Centers. The Transaction Agreement contains (among other things) representations, warranties, and covenants of the parties. Until the closing of the Transaction, OTPP has agreed, subject to certain exceptions, to, and to cause the Metronode Group to, conduct business in the ordinary course consistent with past practice. The completion of the Transaction is subject to certain closing conditions, including regulatory approval. There is no financing condition to the Transaction. The Transaction is expected to close in the first half of 2018. The Transaction Agreement provides Equinix Australia with certain limited termination rights. Additionally, either party may terminate the Transaction Agreement if any of the conditions precedent have not been satisfied by June 30, 2018 and have not (where capable of waiver) been waived by the party or parties entitled to do so under the Transaction Agreement.

Proposed Acquisition of the Infomart

On February 11, 2018, we entered into an agreement with ASB Allegiance Data Centers, LLC (“ASB”), an indirect wholly-owned subsidiary of ASB Real Estate Investments, a division of ASB Capital Management, LLC, pursuant to which we agreed to acquire, subject to closing conditions, the Infomart Dallas (the “Infomart”) through purchase of the direct and indirect subsidiaries of ASB which currently own the Infomart. The acquisition is expected to close inmid-2018, subject to satisfaction of closing conditions. At the closing of the acquisition (the “Closing”), as consideration for the Infomart, we will deliver to ASB $31.0 million in cash, subject to customary adjustments, and will issue to ASB $750.0 million aggregate principal amount of 5.000% senior unsecured notes. The notes will be issued in five new series: (i) $150.0 million principal amount of 5.000% senior notes maturing on the12-month anniversary of the Closing; (ii) $150.0 million principal amount of 5.000% senior notes maturing on the18-month anniversary of the Closing; (iii) $150.0 million principal amount of 5.000% senior notes maturing on the24-month anniversary of the Closing; (iv) $150.0 million principal amount of 5.000% senior notes maturing on the30-month anniversary of the Closing; and (v) $150.0 million principal amount of 5.000% senior notes maturing on the36-month anniversary of the Closing. The notes will pay interest semi-annually. The notes will be general unsecured obligations and will rank equally with our other unsecured senior indebtedness, including the notes offered hereby. The notes will be subject to restrictive covenants substantially similar to the covenants governing the notes offered hereby, including limitations on liens, limitations on asset sales and mergers and consolidations, and limitations on sale and leaseback transactions. Upon a Change of Control Triggering Event (as defined in the “Description of Notes—Change of Control Triggering Event”) we will be required to make an offer to purchase the notes at a purchase price equal to 101% of the principal amount of the notes on the date of purchase, plus accrued interest, if any, to, but excluding, the date of purchase. The notes will provide that upon certain customary events of default occurring and continuing, the principal of the notes and any accrued and unpaid interest may become immediately due and payable. In the case of certain events of bankruptcy or insolvency relating to us, the principal amount of the notes together with any accrued and unpaid interest through the occurrence of such event will automatically become and be immediately due and payable.

Guarantees The notes will not be guaranteed by any of our subsidiaries.

Covenants The indenture and the supplemental indenture governing the notes will contain covenants that limit our ability and the ability of our restricted subsidiaries to, among other things:

• incur liens;

(1) For a discussion of one of our primarynon-GAAP metrics, adjusted EBITDA, and a reconciliation to income from operations, see ournon-GAAP financial measures discussion in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” incorporated by reference in this prospectus supplement and the accompanying prospectus from our Annual Report on Form10-K for the year ended December 31, 2017.

(2) Total debt includes debt, net of premiums, discounts, debt issuance costs, capital leases and other financing obligations.

(3) The following ratios are calculated in a manner consistent with our financial statements, which may not be consistent with the manner in which such ratios would be calculated under the supplemental indenture governing the notes.

(4) Pro forma total debt to adjusted EBITDA ratio is presented as pro forma total debt, after giving pro forma effect to the sale of the notes, gross of discounts and unamortized debt issuance costs, divided by adjusted EBITDA for the twelve months ended December 31, 2017. The ratio does not reflect funding needed to close the proposed acquisitions of the Infomart and the Metronode Group, including the issuance of $750 million of senior notes as part of the consideration in connection with the proposed acquisition of the Infomart, and in each case does not reflect the related adjusted EBITDA. See “Prospectus Summary—Recent Developments.”

(5) Pro forma net debt to adjusted EBITDA ratio is presented as pro forma total debt, after giving pro forma effect to the sale of the notes, gross of discounts and unamortized debt issuance costs, less pro forma cash, cash equivalents and short-term and long-term investments, after giving pro forma effect to the sale of the notes, divided by adjusted EBITDA for the twelve months ended December 31, 2017. The ratio does not reflect funding needed to close the proposed acquisitions of the Infomart and the Metronode Group, including the issuance of $750 million of senior notes as part of the consideration in connection with the proposed acquisition of the Infomart, and in each case does not reflect the related adjusted EBITDA. See “Prospectus Summary—Recent Developments.”

(6) LQA adjusted EBITDA is calculated by multiplying our adjusted EBITDA for the three months ended December 31, 2017 by four. A number of factors, such as fluctuations in our quarterly operating results as discussed in the “Risk Factors” section of our Annual Report on Form10-K for the year ended December 31, 2017 and other factors may cause adjusted EBITDA generated in a particular three-month period to not be comparable to adjusted EBITDA generated in any twelve-month period (or full fiscal year). Our LQA adjusted EBITDA may be different from our actual results for any twelve-month period and such differences could be material.

(7) Pro forma total debt to LQA adjusted EBITDA ratio is presented as pro forma total debt, after giving pro forma effect to the sale of the notes, gross of discounts and unamortized debt issuance costs, divided by our LQA adjusted EBITDA for the period ended December 31, 2017. See footnote (6) above. The ratio does not reflect funding needed to close the proposed acquisitions of the Infomart and the Metronode Group, including the issuance of $750 million of senior notes as part of the consideration in connection with the proposed acquisition of the Infomart, and in each case does not reflect the related adjusted EBITDA. See “Prospectus Summary—Recent Developments.”

(8) Pro forma net debt to LQA adjusted EBITDA ratio is presented as pro forma total debt, after giving pro forma effect to the sale of the notes, gross of discounts and unamortized debt issuance costs, less pro forma cash, cash equivalents and short-term and long-term investments, after giving pro forma effect to the sale of the notes, divided by our LQA adjusted EBITDA for the period ended December 31, 2017. See footnote (6) above. The ratio does not reflect funding needed to close the proposed acquisitions of the Infomart and the Metronode Group, including the issuance of $750 million of senior notes as part of the consideration in connection with the proposed acquisition of the Infomart, and in each case does not reflect the related adjusted EBITDA. See “Prospectus Summary—Recent Developments.”

Risk Factors

An investment in the notes involves certain risks. You should carefully consider the risk factors described under “Risk Factors” in our most recent Annual Report on Form10-K, as well as the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision. Additional risks and uncertainties not now known to us or that we now deem immaterial may also adversely affect our business or financial performance. Our business, financial condition, results of operations or cash flows could be materially adversely affected by any of these risks. The market or trading price of the notes could decline due to any of these risks or other factors, and you may lose all or part of your investment.

Risks Relating to the Notes

References to “Equinix,” the “Company,” “we,” “our” and “us” and similar terms in this section “Risk Factors—Risks Relating to the Notes” mean Equinix, Inc. and not any of its subsidiaries.

Our subsidiaries will not guarantee the notes. We depend in large part on the cash flow from our subsidiaries to meet our obligations, and your claims will be subordinated to all of the creditors of these subsidiaries.

Our subsidiaries will not guarantee the notes. Our subsidiaries are separate and distinct legal entities with no obligation to pay any amounts due pursuant to the notes or to provide us with funds for our payment obligations. Substantially all of our operations are conducted through our subsidiaries and we derive substantially all our revenues from our subsidiaries, and substantially all of our operating assets are owned by our subsidiaries. As a result, our cash flow and our ability to service our indebtedness, including the notes, depends in large part on the earnings of our subsidiaries and on the distribution of earnings, loans or other payments to us by these subsidiaries. Payments to us by our subsidiaries also will be contingent upon their earnings and their business considerations. In addition, the ability of our subsidiaries to make any dividend, distribution, loan or other payment to us could be subject to statutory or contractual restrictions. Because we depend in large part on the cash flow of our subsidiaries to meet our obligations, these types of restrictions may impair our ability to make scheduled interest and principal payments on the notes. Our subsidiaries held approximately 89% of our consolidated assets as of December 31, 2017.

The notes will be unsecured and effectively subordinated to any of our existing or future secured indebtedness and structurally subordinated to all of the liabilities of our subsidiaries.

The notes will be our general unsecured senior obligations, ranking equal in right of payment with our existing and any future unsubordinated indebtedness. However, because they are unsecured, the notes will be effectively junior to any of our existing or future secured indebtedness to the extent of the value of the assets securing such debt. As of December 31, 2017, we had approximately $10.2 billion of consolidated indebtedness. As of December 31, 2017, after giving pro forma effect to the sale of the notes, we would have had total consolidated indebtedness of approximately $11.1 billion, approximately $33.4 million of which would have represented secured indebtedness, which excludes approximately $1.7 billion of capital lease and other financing obligations, and does not reflect funding needed to close the proposed acquisitions of the Infomart and the Metronode Group, including the issuance of $750 million of

S-16

senior notes as part of the consideration in connection with the proposed acquisition of the Infomart. See “Prospectus Summary—Recent Developments.”

In addition, the notes will be structurally subordinated to all of the liabilities of our subsidiaries, which may include indebtedness, trade payables, guarantees, lease obligations and letter of credit obligations. In the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets of the subsidiaries are made available for distribution to us. As of December 31, 2017, after giving pro forma effect to the sale of the notes, our subsidiaries would have had $2.0 billion of indebtedness (excluding trade payables and intercompany items and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP), which includes $1.6 billion of capital lease and other financing obligations, all of which would be structurally senior to the notes.

The supplemental indenture governing the notes will permit us and our subsidiaries to incur significant amounts of additional indebtedness, including secured indebtedness. In the event that we are declared bankrupt, become insolvent or liquidate or reorganize, our assets that serve as collateral under any such secured indebtedness would be made available to satisfy the obligations under the secured indebtedness before those assets may be used to satisfy our obligations with respect to the notes. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of the notes may receive less, ratably, than holders of secured indebtedness.

Our debt agreements allow us and our subsidiaries to incur significantly more debt, which could exacerbate the other risks described herein, as well as the risks described in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus.

The terms of our debt instruments, including the supplemental indenture governing the notes offered hereby and the agreement governing our credit facility, permit us and our subsidiaries to incur additional indebtedness. Additional debt may be necessary for many reasons, including to adequately respond to competition, to comply with regulatory requirements related to our service obligations or for financial reasons alone. Incremental borrowings or borrowings at maturity on terms that impose additional financial risks to our various efforts to improve our operating results and financial condition could exacerbate the other risks described herein, as well as the risks described in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus.

As of December 31, 2017, we had approximately $1.9 billion of additional liquidity available to us from our $2.0 billion revolving credit facility, subject to our compliance with the financial covenants and other conditions precedent set forth in the credit agreement relating to such facility.

S-17

Our credit facility and other existing debt instruments have restrictive covenants that could limit our financial flexibility.

The indentures relating to our existing senior notes and the agreement governing our existing credit facility contain financial and other restrictive covenants that limit our ability to engage in activities that may be in our long-term best interests.

Our ability to borrow under our revolving credit facility is subject to compliance with certain financial covenants, including leverage and interest coverage ratios. Our revolving credit facility and term loan facility include other restrictions that, among other things: limit our ability to incur indebtedness; grant liens; engage in mergers, consolidations and liquidations; make asset dispositions, restricted payments and investments; enter into transactions with affiliates; and amend, modify or prepay certain indebtedness. The indentures related to our existing senior notes contain limitations on our ability to effect mergers and change of control events, as well as other limitations, including:

• limitations on the declaration and payment of dividends or other restricted payments;

• limitations on incurring additional indebtedness or issuing preferred stock;

• limitations on the creation of certain liens;

• limitations on incurring restrictions on the ability of certain of our subsidiaries to pay dividends or other payments;

• limitations on transactions with affiliates; and

• limitations on the sale of assets.

Our failure to comply with these covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all of our debts. We do not have sufficient working capital to satisfy our debt obligations in the event of an acceleration of all or a significant portion of our outstanding indebtedness.

The indenture relating to the notes offered hereby will not contain many of the limitations described above that are applicable to our other indebtedness.

The limited covenants in the indenture and the supplemental indenture governing the notes offered hereby and the terms of the notes will not provide protection against some types of corporate events and may not protect your investment.

The indenture and the supplemental indenture governing the notes offered hereby will not:

• require us to maintain any financial ratios or specific levels of net worth, revenues, income, cash flow or liquidity and, accordingly, will not protect holders of the notes in the event that we experience significant adverse changes in our financial condition or results of operations;

• restrict our subsidiaries’ ability to issue securities or otherwise incur indebtedness that would be senior to our equity interests in our subsidiaries and therefore would be structurally senior to the notes;

��� limit our ability to incur unsecured indebtedness that is equal in right of payment to the notes;

S-18

• restrict our ability to repurchase or prepay our securities;

• restrict our ability to make investments or to repurchase or pay dividends or other distributions or make other payments in respect of our common stock or other securities ranking junior to the notes; or

• restrict our ability to enter into highly leveraged transactions.

In addition, the limitation on liens and limitation on sale and leaseback transactions covenants contained therein with respect to property held by us or our restricted subsidiaries contain exceptions that will allow us to create, grant or incur liens or security interests in a number of circumstances.

As a result of the foregoing, when evaluating the terms of the notes, you should be aware that the terms of the indenture and the supplemental indenture governing the notes offered hereby and the notes will not restrict our ability to engage in, or to otherwise be a party to, a variety of corporate transactions, circumstances and events, such as certain acquisitions, refinancings or recapitalizations that could substantially and adversely affect our capital structure and the value of the notes. For these reasons, you should not consider the covenants in the indenture as a significant factor in evaluating whether to invest in the notes.

We may not be able to repurchase the notes upon a Change of Control Triggering Event.

Upon the occurrence of a Change of Control Triggering Event (as defined in “Description of Notes—Change of Control Triggering Event”), we will be required to make an offer to purchase each holder’s notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to, but not including, the date of repurchase.

If we experience a Change of Control Triggering Event, we may not have sufficient financial resources available to satisfy our obligations to repurchase the notes. Our failure to repurchase the notes as required under the supplemental indenture governing the notes would result in a default under the indenture, which could result in defaults under our and our subsidiaries’ other debt agreements and have material adverse consequences for us and the holders of the notes.

See “Description of Notes—Change of Control Triggering Event.” Moreover, if holders of the notes elect to have their notes repurchased by us (or holders of our other existing and future debt securities, such as our existing senior notes that have a right to require us to repurchase their securities upon such a Change of Control Triggering Event, elect to have their debt securities repurchased by us) it could cause a default under our existing or future debt, even if the Change of Control Triggering Event itself does not result in a default under existing or future debt, due to the financial effect of such repurchase on us.

The provisions in the indenture and the supplemental indenture governing the notes relating to change of control transactions will not necessarily protect you in the event of a highly leveraged transaction.

While the supplemental indenture and the notes offered hereby contain terms intended to provide protections to holders upon the occurrence of certain events involving significant corporate transactions or our creditworthiness, these terms are limited and may not be sufficient to protect your investment in the notes. The provisions in the indenture and the supplemental

S-19

indenture governing the notes offered hereby relating to change of control transactions will not necessarily afford you protection in the event of a highly leveraged transaction that may adversely affect you, including a reorganization, restructuring, merger or other similar transaction involving us. These transactions may not involve a change in voting power or beneficial ownership or, even if they do, may not involve a change of the magnitude required under the definition of change of control repurchase event in the indenture to trigger these provisions, including the requirement that the transactions be accompanied or followed within 60 days by a downgrade in the rating of the notes below the rating of the notes in effect on the day of the original issuance of the notes. Except as described under “Description of Notes—Change of Control Triggering Event” the indenture will not contain provisions that permit the holders of the notes to require us to repurchase the notes in the event of a takeover, recapitalization or similar transaction. Further, the definition of change of control, which is a condition precedent to a change of control repurchase event, includes a phrase relating to the sale, transfer, conveyance or other disposition of “all or substantially all” of our assets. There is no precisely established definition of the phrase “substantially all” under applicable law. Accordingly, your ability to require us to repurchase your notes as a result of a sale, transfer, conveyance or other disposition of less than all of our assets to another individual, group or entity may be uncertain.

An active trading market for the notes may not develop or be maintained; many factors affect the trading market and value of the notes.

The notes are a new issue of securities with no trading history or established trading market. We will apply, following the completion of this offering, to have the notes listed on the Exchange and admitted for trading on the Official List of the Exchange on or prior to the first interest payment date. However, no assurance can be given that the notes will become or will remain listed. If such listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time. We cannot assure you that a trading market for the notes will ever develop or, if a trading market develops, that it will be maintained or provide adequate liquidity, that holders will be able to sell any of the notes at a particular time (if at all) or that the prices holders receive if or when they sell the notes will be above their initial offering price.

The market valuation of the notes may be exposed to substantial volatility.

A real or perceived economic downturn or higher interest rates could cause a decline in the value of the notes, and to high-yield bonds generally, and thereby negatively impact the market for high-yield bonds, and more specifically, the notes. Because the notes may be thinly traded, it may be more difficult to sell and accurately value the notes. In addition, the entire high-yield bond market can experience sudden and sharp price swings, which can be exacerbated by large or sustained sales by major investors in the notes, a high-profile default by another issuer, or simply a change in the market’s psychology regarding high-yield notes. This risk is exacerbated by general market volatility, which has been characteristic of global financial markets in recent periods, and ongoing macroeconomic uncertainty.

Our credit ratings may not reflect all of the risks of an investment in the notes.

The credit ratings on the notes may not reflect the potential impact of all of the risks related to structure and other factors on the value of the notes. In addition, actual or anticipated changes in our credit ratings will generally affect the market value of the notes.

The unaudited pro forma financial information incorporated by reference in this prospectus supplement is presented for illustrative purposes only, and may not be an indication of our financial condition or results of operations following our purchase from Verizon Communications Inc. (“Verizon”), completed on May 1, 2017, of Verizon’s colocation business consisting of 29 data center buildings, located in the United States, Brazil and Colombia (the “Selected Verizon Data Center Business” or the “Acquisition”) for a cash purchase price of approximately $3.6 billion, subject to certain adjustments.

The unaudited pro forma condensed combined financial information incorporated by reference in this prospectus supplement is presented for illustrative purposes only and may not be an indication of our actual financial condition or results of operations following the Acquisition. The unaudited pro forma condensed combined financial information was derived from the historical consolidated financial statements of Equinix and the abbreviated financial statements of the Selected Verizon Data Center Business and certain adjustments and assumptions were made regarding Equinix. The unaudited pro forma condensed combined financial information does not reflect all costs that were incurred or are expected to be incurred by us in connection with the Acquisition. For example, the impact of any incremental costs incurred in integrating Equinix and the Selected Verizon Data Center Business is not reflected in the unaudited pro forma condensed combined financial information. As a result, our actual financial condition and results of operations following the Acquisition may not be consistent with, or evident from, the unaudited pro forma condensed combined financial information. Since the unaudited pro forma condensed combined financial information was first presented, the intangible assets, goodwill, property, plant and equipment, working capital and deferred taxes have been updated in our consolidated balance sheet as of December 31, 2017, to reflect updates in valuation analysis. We also finalized the selection of the specific data center sites that we acquired and formalized agreements with Verizon to provide pre-existing space and services to Verizon at the closing of the Acquisition. See Equinix’s Form10-K for the year ended December 31, 2017, which is also incorporated by reference in this prospectus supplement. Further, other assumptions used in preparing the unaudited pro forma condensed combined financial information may not prove to be accurate, and other factors may affect our actual financial condition or results of operations following the Acquisition. The trading price of the notes may be adversely affected if our actual results fall short of the historical results reflected in the unaudited pro forma condensed combined financial information incorporated by reference in this prospectus supplement.

Holders of the notes will receive payments solely in euros subject to limited exceptions.

All payments of interest on and the principal of the notes and any redemption price for the notes will be made in euros, subject to certain limited exceptions. We, the underwriters, the trustee and the paying agent with respect to the notes will not be obligated to convert, or to assist any registered owner or beneficial owner of notes in converting, payments of interest, principal, any redemption price or any additional amount in euros made with respect to the notes into U.S. dollars or any other currency.

Holders of the notes may be subject to the effects of foreign currency exchange rate fluctuations, as well as possible exchange controls, relating to the euro.

The initial investors in the notes will be required to pay for the notes in euros. Neither we nor the underwriters will be obligated to assist the initial investors in obtaining euros or in

S-21

converting other currencies into euros to facilitate the payment of the purchase price for the notes.

An investment in any security denominated in, and all payments with respect to which are to be made in, a currency other than the currency of the country in which an investor in the notes resides or the currency in which an investor conducts its business or activities (the “investor’s home currency”), entails significant risks not associated with a similar investment in a security denominated in the investor’s home currency. In the case of the notes offered hereby, these risks may include the possibility of:

• significant changes in rates of exchange between the euro and the investor’s home currency; and

• the imposition or modification of foreign exchange controls with respect to the euro or the investor’s home currency.

We have no control over a number of factors affecting the notes offered hereby and foreign exchange rates, including economic, financial and political events that are important in determining the existence, magnitude and longevity of these risks and their effects. Changes in foreign currency exchange rates between two currencies result from the interaction over time of many factors directly or indirectly affecting economic and political conditions in the countries issuing such currencies, and economic and political developments globally and in other relevant countries. Foreign currency exchange rates may be affected by, among other factors, existing and expected rates of inflation, existing and expected interest rate levels, the balance of payments between countries, and the extent of governmental surpluses or deficits in various countries. All of these factors are, in turn, sensitive to the monetary, fiscal and trade policies pursued by the governments of various countries important to international trade and finance. Moreover, the recent global economic crisis and the actions taken or to be taken by various national governments in response to the crisis could significantly affect the exchange rates between the euro and the investor’s home currency.

The exchange rates of an investor’s home currency for euros and the fluctuations in those exchange rates that have occurred in the past are not necessarily indicative of the exchange rates or the fluctuations therein that may occur in the future. Depreciation of the euro against the investor’s home currency would result in a decrease in the investor’s home currency equivalent yield on a note, in the investor’s home currency equivalent of the principal payable at the maturity of that note and generally in the investor’s home currency equivalent market value of that note. Appreciation of the euro in relation to the investor’s home currency would have the opposite effects.

The European Union or one or more of its member states may, in the future, impose exchange controls and modify any exchange controls imposed, which controls could affect exchange rates, as well as the availability of euros at the time of payment of principal of, interest on, or any redemption payment or additional amounts with respect to, the notes.

This description of foreign exchange risks does not describe all the risks of an investment in securities, including, in particular, the notes, that are denominated or payable in a currency other than an investor’s home currency. You should consult your own financial and legal advisors as to the risks involved in an investment in the notes.

S-22

The notes permit us to make payments in U.S. dollars if we are unable to obtain euros and market perceptions concerning the instability of the euro could materially adversely affect the value of the notes.

If the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euros will be converted into U.S. dollars on the basis of the then most recently available market exchange rate for euros, as determined by us in our sole discretion. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the supplemental indenture governing the notes. This exchange rate may be materially less favorable than the rate in effect at the time the notes were issued or as would be determined by applicable law. Such developments, or market perceptions concerning these and related issues, could materially adversely affect the value of the notes and you may lose a significant amount of your investment in the notes. See “Exchange Rates.”

In a lawsuit for payment on the notes, an investor may bear currency exchange risk.

The indenture is, and the notes will be, governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the notes would be required to render the judgment in euros. However, the judgment would be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the notes, investors would bear currency exchange risk until a New York state court judgment is entered, which could be a significant amount of time. A federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the notes would apply New York law.

In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the notes in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The date used to determine the rate of conversion of euro into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

Trading in the clearing systems is subject to minimum denomination requirements.

The terms of the notes provide that the notes will be issued only with a minimum denomination of€100,000 and multiples of€1,000 in excess thereof. The notes may be traded in amounts in excess of€100,000 that are not integral multiples of€100,000. In such a case, a holder of notes who, as a result of trading such amounts, holds a principal amount of less than€100,000 may not receive a definitive certificate in respect of such holding (should definitive certificates be printed) and would need to purchase a principal amount of notes such that its holding amounts to at least€100,000.

Ratio of Earnings to Fixed Charges and Preferred Stock

Dividends

The following table sets forth our consolidated ratio of earnings to fixed charges and ratio of earnings to combined fixed charges and preferred stock dividends:

	Years ended December 31,
	2013		2014		2015		2016		2017
Ratio of earnings to fixed charges		1.4x		1.2x		1.6x		1.3x		1.5x
Ratio of earnings to combined fixed charges and preferred stock dividends(1)		1.4x		1.2x		1.6x		1.3x		1.5x

(1) We had no preferred securities outstanding for the periods presented; therefore, the ratio of earnings to combined fixed charges and preferred stock dividends is the same as the ratio of earnings to fixed charges.

In calculating the ratio of earnings to fixed charges, earnings consist of net income (loss) from continuing operations before income tax expense and fixed charges. Fixed charges consist of interest expense, including such portion of rental expense that was attributed to interest, and amortization of capitalized interest. The portion of rent expense that was attributed to interest represents a reasonable approximation of the interest factor.

Description of Notes

This section describes the    % senior notes due 2024 (the “notes”) that will be issued by the Company. The Company will issue the notes under a supplemental indenture (the “Supplemental Indenture”) to that certain base indenture, dated as of December 12, 2017 (together with the Supplemental Indenture, the “Indenture”), between itself and U.S. Bank National Association, as Trustee (the “Trustee”). The following is a summary of the material provisions of the Indenture. The Indenture will comply with the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to certain provisions of the Trust Indenture Act. You can find definitions of certain capitalized terms used in this description under “—Certain Definitions.”

For purposes of this section, references to the “Company” include only Equinix, Inc. and not its subsidiaries. You are encouraged to read the Indenture because it, and not this description, defines your rights as a holder of the notes. Copies of the Indenture are available upon request to the Company at the address indicated under “Where You Can Find More Information” in this prospectus supplement.

The Company will issue the notes in fully registered form in minimum denominations of€100,000 and integral multiples of€1,000 in excess thereof.

Unless otherwise specified, the euro/U.S. dollar rate of exchange used in this prospectus supplement is€1.00 = $1.2297, as of noon, New York City time on February 26, 2018 on the Bloomberg page “BFIX.”

Payments on the Notes; Paying Agent

Elavon Financial Services DAC, UK Branch will initially act as paying agent, and Elavon Financial Services DAC will initially act as Registrar for the notes. Initially, the paying agent’s office in London, United Kingdom and the Registrar’s office in Dublin, Ireland will serve as the Company’s office and agency for these respective purposes. The notes may be presented for registration or transfer and exchange at the office of the Registrar. The Company may change any paying agent and Registrar without notice to holders of the notes (the “Holders”). In addition, the Company or any of its Subsidiaries may act as paying agent in connection with the notes other than for the purposes of effecting a redemption described under “—Redemption upon a Tax Event” or “—Redemption” or an offer to purchase the notes described under “—Change of Control Triggering Event.” The Company will make all payments insame-day funds.

The Company may elect that payment of interest on notes be made by wire transfer or by check mailed to the address of the appropriate person as it appears on the security register. So long as the registered owner of the notes is a common depositary of Euroclear and Clearstream or their nominee, payment of principal and interest shall be made in accordance with the requirements of Euroclear and Clearstream. See “—Book-Entry System and Form of Notes” below.

No service charge will be made for any registration of a transfer, exchange or redemption of the notes, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection with any such registration of transfer or exchange (but not for a redemption).

S-28

Listing

We will apply, following the completion of this offering, to have the notes listed on The International Stock Exchange (the “Exchange”) and admitted for trading on the Official List of the Exchange on or prior to the first interest payment date. However, no assurance can be given that the notes will become or will remain listed. If such listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time.

Principal, Maturity and Interest

The Company is issuing€750,000,000 aggregate principal amount of notes in this offering and may issue an unlimited principal amount of additional notes at later dates under the same Indenture as the notes (the “Additional Notes”). Any Additional Notes that the Company issues in the future will be identical in all respects to the notes and will be treated as a single class for all purposes under the Indenture with the notes offered hereby, except that such Additional Notes will have different issuance dates and may have different issuance prices;provided that if any such Additional Notes are not fungible with the notes offered hereby for U.S. federal income tax purposes, such Additional Notes will have one or more separate ISIN numbers. Unless the context requires otherwise, references to “notes” for all purposes of the Indenture and this “Description of Notes” include any Additional Notes that are actually issued.

The notes will mature on March 15, 2024, unless earlier redeemed or repurchased.

Interest on the notes will accrue at a rate of    % per annum. Interest on the notes will be payable semiannually in arrears on March 15 and September 15 of each year commencing on September 15, 2018. The Company will pay interest to those persons who were holders of record on the March 1 or September 1 immediately preceding each interest payment date. Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a360-day year comprised of twelve30-day months (US 30/360).

The notes will not be entitled to the benefit of any mandatory sinking fund.

Ranking

The notes will be general senior obligations of the Company. The Holders’ right to payment under these notes will be:

• effectively subordinated to all of the existing and any future secured indebtedness of the Company, including debt outstanding under any secured Bank Facility or secured by any mortgage, to the extent of the assets securing such debt;

• structurally subordinated to any existing and future indebtedness and other liabilities (including trade payables) of any Subsidiaries of the Company;

• equal in right of payment to all existing and any future senior indebtedness of the Company; and

• senior in right of payment to any existing and future subordinated indebtedness of the Company.

S-29

At December 31, 2017, after giving effect to this offering:

• the Company would have had total consolidated indebtedness of approximately $11.1 billion, approximately $33.4 million of which would have represented secured indebtedness, which excludes approximately $1.7 billion of capital lease and other financing obligations, and does not reflect funding needed to close the proposed acquisitions of the Infomart and the Metronode Group, including the issuance of $750 million of senior notes as part of the consideration in connection with the proposed acquisition of the Infomart.

• if the Company borrowed all of the approximately $2.0 billion available under its revolving credit facility, $2.0 billion of such borrowings would have been unsecured indebtedness; and

• the Subsidiaries of the Company would have had approximately $2.0 billion of indebtedness (excluding trade payables and intercompany items and liabilities of a type not required to be reflected on a balance sheet of such Subsidiaries in accordance with GAAP), which includes $1.6 billion of capital lease and other financing obligations, all of which would have been structurally senior to the notes.

Issuance in Euro

Initial holders will be required to pay for the notes in euro, and all payments of interest and principal, including payments made upon any redemption of the notes, will be payable in euro. If, on or after the date of this prospectus supplement, the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. The amount payable on any date in euro will be converted into U.S. dollars on the basis of the then most recently available market exchange rate for euro. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes. Neither the Trustee nor the paying agent shall have any responsibility for any calculation or conversion in connection with the forgoing.

Investors will be subject to foreign exchange risks as to payments of principal and interest that may have important economic and tax consequences to them. See “Risk Factors” in this prospectus supplement.

Additional Amounts

All payments made by the Company under or with respect to the notes will be made free and clear of, and without withholding or deduction for or on account of, any Tax, unless the withholding or deduction of such Tax is then required by law. If any deduction or withholding by any applicable withholding agent for or on account of any Taxes imposed or levied by or on behalf of the United States or a taxing authority of or in the United States (a “Tax Jurisdiction”) will at any time be required to be made in respect of any payments made by the Company under or with respect to the notes, including payments of principal, redemption price, purchase price, interest or premium, then the Company will pay such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by each beneficial owner of the notes that is not a U.S. Person (as defined below) after

S-30

such withholding, deduction or imposition (including any such withholding, deduction or imposition in respect of any such Additional Amounts) will equal the respective amounts that would have been received in respect of such payments in the absence of such withholding or deduction;provided, however, that no Additional Amounts will be payable with respect to:

(1) any Taxes, to the extent such Taxes would not have been imposed but for the holder of a note (or the beneficial owner for whose benefit such holder holds such note) or a fiduciary, settlor, beneficiary, member or shareholder of the holder if the holder is an estate, trust, partnership or corporation, or a person holding a power over an estate or trust administered by a fiduciary holder, being considered as:

(a) having a current or former connection with the relevant Tax Jurisdiction (other than a connection arising solely from the ownership or disposition of such note, the enforcement of rights under such note or the receipt of any payments in respect of such note), including being or having been a citizen or resident of such Tax Jurisdiction, being or having engaged in a trade or business in such Tax Jurisdiction or having or having had a permanent establishment in such Tax Jurisdiction; or

(b) being or having been a personal holding company, a passive foreign investment company or a controlled foreign corporation for U.S. federal income tax purposes or a corporation that has accumulated earnings to avoid U.S. federal income tax;

(2) any holder that is not the sole beneficial owner of the notes, or a portion of the notes, or that is a fiduciary, partnership or limited liability company, but only to the extent that a beneficial owner with respect to the holder, a beneficiary or settlor with respect to the fiduciary, or a beneficial owner or member of the partnership or limited liability company would not have been entitled to the payment of Additional Amounts had the beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

(3) any Taxes required to be withheld by any paying agent from any payment of principal of or interest on any note, if such payment can be made without such withholding by at least one other paying agent;

(4) any Taxes, to the extent such Taxes were imposed as a result of the presentation of a note for payment more than 30 days after the relevant payment is first made available for payment to the holder (except to the extent that the holder or beneficial owner would otherwise have been entitled to Additional Amounts had the note been presented on the last day of such 30 day period);

(5) any Taxes that are payable otherwise than by deduction or withholding from a payment on or with respect to the notes;

(6) any U.S. federal withholding tax imposed as a result of the beneficial owner:

(a) being a controlled foreign corporation for U.S. federal income tax purposes related to the Company;

(b) being or having been a“10-percent shareholder” of the Company as defined in Section 871(h)(3) of the Code; or

(c) being a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business;

S-31

(7) any estate, inheritance, gift, sales, transfer, excise, wealth, capital gains, personal property or similar Taxes;

(8) any Taxes, to the extent such Taxes are imposed or withheld by reason of the failure of the holder or beneficial owner of notes to comply with any certification, identification, information or other reporting requirements, whether required by statute, treaty, regulation or administrative practice of a Tax Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Tax Jurisdiction (including, without limitation, a certification that the holder or beneficial owner is not resident in the Tax Jurisdiction), but in each case, only to the extent the holder or beneficial owner is legally eligible to provide such certification or documentation;

(9) any Taxes that are imposed or withheld pursuant to Sections 1471 through 1474 of the Code as of the date of the Indenture (or any amended or successor version that is substantively comparable), any regulations promulgated thereunder or any other official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code as of the date of Indenture (or any amended or successor version described above) or any intergovernmental agreements (and any related law, regulation or official administrative guidance) implementing the foregoing; or

(10) any combination of items (1) through (9) above.

Except as specifically provided under this heading “Additional Amounts,” the Company will not be required to make any payment for any Tax.

If the Company becomes aware that it will be obligated to pay Additional Amounts with respect to any payment under or with respect to the notes, the Company will deliver to the Trustee and paying agent promptly prior to the date of that payment an officers’ certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable. The officers’ certificate must also set forth any other information reasonably necessary to enable the paying agent to pay Additional Amounts to holders on the relevant payment date. The Trustee and paying agent shall be entitled to rely solely on such officers’ certificate as conclusive proof that such payments are necessary.

The Company, if it is the applicable withholding agent, will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the relevant Tax authority in accordance with applicable law. The Company will use its reasonable efforts to obtain Tax receipts from each Tax authority evidencing the payment of any Taxes so deducted or withheld.

The Company will furnish to the Trustee upon reasonable written request, within a reasonable time after the date the payment of any Taxes so deducted or withheld is made, certified copies of Tax receipts evidencing payment by the Company, or if, notwithstanding such entity’s efforts to obtain receipts, receipts are not obtained, other reasonable evidence of payments by such entity.

Whenever in the Indenture or in this “Description of Notes” there is mentioned, in any context, the payment of amounts based upon the principal amount of the notes or of principal, interest or of any other amount payable under, or with respect to, any of the notes, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

S-32

The above obligations will survive any termination, defeasance or discharge of the Indenture, any transfer by a holder or beneficial owner of its notes, and will apply, mutatis mutandis, to any successor Person to the Company.

As used under this heading “Additional Amounts” and under the heading “Redemption upon a Tax Event,” the term “United States” means the United States of America, any state thereof and the District of Columbia, and the term “U.S. Person” means any person that is, for U.S. federal income tax purposes, an individual who is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia or any estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Redemption upon a Tax Event

The Company may redeem the notes, in whole but not in part, at its option, at any time upon giving not less than 30 nor more than 60 days’ prior notice to the Holders of the notes and the Trustee (which notice will be irrevocable) at a redemption price equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest to, but excluding, the date of redemption (“Tax Event Redemption Date”) and all Additional Amounts (if any) then due and which will become due on the Tax Event Redemption Date as a result of the redemption or otherwise (subject to the right of Holders of the notes on the relevant record date to receive interest due on the relevant interest payment date occurring on or prior to the redemption date and Additional Amounts (if any) in respect thereof), if, on the next date on which any amount would be payable in respect of the notes, the Company is or, based upon an opinion of independent tax counsel of recognized standing in the relevant Tax Jurisdiction, would be required to pay Additional Amounts in respect of the notes and cannot avoid such payment obligation by taking reasonable measures available to the Company, and such requirement arises as a result of:

(1) any amendment to, or change in, the laws (or any regulations or rulings promulgated thereunder) of a relevant Tax Jurisdiction, which change or amendment is announced and becomes effective after the Issue Date; or

(2) any amendment to, or change in, an official written interpretation or application of such laws, regulations or rulings (including by virtue of a holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice), which amendment or change is announced and becomes effective after the Issue Date.

The Company will not give any such notice of redemption earlier than 60 days prior to the earliest date on which the Company would be obligated to pay Additional Amounts if a payment in respect of the notes was then due, and the obligation to pay Additional Amounts must be in effect at the time such notice is given. Before the Company publishes or delivers a notice of redemption in respect of a Tax Event Redemption Date as described above, the Company will deliver to the Trustee an officers’ certificate to the effect that the Company cannot avoid the obligation to pay Additional Amounts by taking reasonable measures available to it and, if required, the opinion of independent tax counsel described above. Any notice of redemption shall otherwise be given pursuant to the procedures described under “—Optional Redemption.” The Trustee shall accept, and will be entitled to conclusively rely on, such an opinion of counsel and such officers’ certificate as sufficient evidence of the existence and satisfaction of the conditions precedent described in clause (1) or (2) above, as applicable, and upon delivery of such

S-33

opinion of counsel and officers’ certificate to the Trustee the Company will be entitled to give notice of redemption hereunder and such notice of redemption will be conclusive and binding on the Holders of the notes.

Redemption

Other than as described in “—Redemption upon a Tax Event” and as set forth below, the notes are not redeemable prior to maturity.

At any time prior to September 15, 2020, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the notes (calculated giving effect to any issuance of Additional Notes) outstanding under the Indenture, at a redemption price equal to    % of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more Equity Offerings;provided that:

(1) at least 65% of the aggregate principal amount of the notes (calculated giving effect to any issuance of Additional Notes) issued under the Supplemental Indenture remains outstanding immediately after the occurrence of such redemption (excluding notes held by the Company and its subsidiaries); and

(2) the redemption must occur within 90 days of the date of the closing of such Equity Offering.

On or after September 15, 2020, the Company may redeem all or a part of the notes, on any one or more occasions, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date, if redeemed during the twelve or eighteen month period beginning on September 15 of each of the years indicated below:

Year	Redemption price of the notes
2020		%
2021		%
2022 and thereafter		100.000%

At any time prior to September 15, 2020, the Company may also redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption (the “Redemption Date”), subject to the rights of Holders of record of notes on the relevant record date to receive interest due on the relevant interest payment date.

Selection and Notice of Redemption

In the event that the Company chooses to redeem less than all of the notes, selection of the notes for redemption will be made by the Trustee:

1. by a method that complies with the requirements, as certified to the Trustee by the Company, of the securities exchange, if any, on which the notes are listed at such time, and in compliance with the requirements of the relevant clearing system;provided that, the

S-34

notes are represented by one or more global notes, beneficial interests in the notes will be selected for redemption by Euroclear and Clearstream in accordance with their respective standard procedures therefor; or

2. if the notes are not listed on a securities exchange, or such securities exchange prescribes no method of selection and the notes are not held through a clearing system or the clearing system prescribes no method of selection, by lot.

No notes of a principal amount of€100,000 or less shall be redeemed in part. The Company will also comply with any other requirements of the securities exchange, if any, on which the notes are listed at such time.

Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each Holder of notes to be redeemed at its registered address (or, in the case of notes represented by global notes, notice will be given in accordance with the applicable procedures of Euroclear or Clearstream) and the Trustee,provided that, if the redemption notice is issued in connection with a defeasance of the notes or satisfaction and discharge of the Indenture governing the notes, the notice of redemption may be delivered more than 60 calendar days before the date of redemption. If any note is to be redeemed in part only, then the notice of redemption that relates to such note must state the portion of the principal amount thereof to be redeemed. A new note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original note (or appropriate adjustments to the amount and beneficial interests in a global note will be made). On and after the redemption date, interest will cease to accrue on notes or portions thereof called for redemption as long as the Company has deposited with the paying agent funds in satisfaction of the applicable redemption price. Any redemption or notice of redemption, other than a notice of redemption delivered pursuant to “—Redemption upon a Tax Event” (which must be irrevocable), may, at our discretion, be subject to one or more conditions precedent.

No Sinking Fund; Offers to Purchase; Open Market Purchases

We are not required to make any mandatory redemption or sinking fund payments with respect to the notes. However, under certain circumstances, we may be required to offer to purchase notes as described under “—Change of Control Triggering Event.” We may at any time and from time to time purchase notes in the open market or otherwise (including pursuant to cash-settled swaps or derivatives), subject to compliance with applicable securities laws.

Holding Company Structure

The Company is a holding company for its Subsidiaries. Substantially all of the Company’s operations are conducted through its Subsidiaries and the Company derives substantially all its revenues from its Subsidiaries, and substantially all of its operating assets are owned by its Subsidiaries. Accordingly, the Company is dependent upon the distribution of the earnings of its Subsidiaries, whether in the form of dividends, advances or payments on account of intercompany obligations, to service its debt obligations. In addition, the claims of the Holders are subject to the prior payment of all liabilities (whether or not for borrowed money) and to any preferred stock interest of such Restricted Subsidiaries. There can be no assurance that, after providing for all prior claims, there would be sufficient assets available from the Company and its

S-35

Subsidiaries to satisfy the claims of the Holders of notes. See “Risk Factors—Our subsidiaries will not guarantee the notes. We depend in large part on the cash flow from our subsidiaries to meet our obligations, and your claims will be subordinated to all of the creditors of these subsidiaries.”

Guarantees

The notes will not be guaranteed by any of the Company’s Subsidiaries.

Change of Control Triggering Event

Upon the occurrence of a Change of Control Triggering Event, unless the Company or a third party has previously or concurrently delivered a redemption notice with respect to all outstanding notes as described under “—Redemption upon a Tax Event” or “—Redemption,” the Company will be required to make an offer to purchase each Holder’s notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of purchase.

Within 30 days following the date upon which the Change of Control Triggering Event has occurred, the Company must send, or cause the Trustee to send, by first class mail (or, in the case of notes represented by global notes, in accordance with the applicable procedures of Euroclear or Clearstream), a notice to each Holder, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days after the date such notice is delivered, other than as may be required by law (the “Change of Control Payment Date”). Holders electing to have a note purchased pursuant to a Change of Control Offer will be required to surrender the note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the note completed and specifying the portion (equal to€100,000 and integral multiples of€1,000 in excess thereof) of such Holder’s notes that it agrees to sell to the Company pursuant to the Change of Control Offer, to the paying agent at the address specified in the notice prior to the close of business on the third business day prior to the Change of Control Payment Date.

If a Change of Control Offer is made, there can be no assurance that the Company will have available funds sufficient to pay the purchase price for all the notes that might be delivered by Holders seeking to accept the Change of Control Offer. In the event the Company is required to purchase outstanding notes pursuant to a Change of Control Offer, the Company expects that it would seek third-party financing to the extent it does not have available funds to meet its purchase obligations. However, there can be no assurance that the Company would be able to obtain such financing. In addition, there can be no assurance that the Company would be able to obtain the consents necessary to consummate a Change of Control Offer from the lenders under agreements governing outstanding Indebtedness that may in the future prohibit the Change of Control Offer. The failure to consummate a Change of Control Offer would constitute an Event of Default under the Indenture. See “Risk Factors—We may not be able to repurchase the notes upon a Change of Control Triggering Event” for more information.

One of the events that constitutes a Change of Control under the Indenture is the disposition of “all or substantially all” of the Company’s assets. This term has not been interpreted under New York law, which is the governing law of the Indenture, to represent a specific quantitative test. As a consequence, if Holders of the notes assert that the Company is required to make a Change

S-36

of Control Offer and the Company elects to contest such assertion, there is uncertainty as to how a court interpreting New York law would interpret the term. Neither the Board of Directors of the Company nor the Trustee may waive the covenant of the Company to make a Change of Control Offer following a Change of Control Triggering Event. Restrictions in the Indenture described herein on the ability of the Company and its Subsidiaries to incur additional Indebtedness and to grant Liens on the property of the Company and the Restricted Subsidiaries may also make more difficult or discourage a takeover of the Company, whether favored or opposed by the management or stockholders of the Company. There can be no assurance that the Company or the acquiring party will have sufficient financial resources to effect a Change of Control Offer. Such restrictions may, in certain circumstances, make more difficult or discourage any leveraged buyout of the Company or any of its Subsidiaries by their respective management. However, the Indenture may not afford the Holders protection in all circumstances from the adverse aspects of a highly leveraged transaction, reorganization, amalgamation, restructuring, merger or similar transaction.

The Company will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all notes validly tendered and not withdrawn under such Change of Control Offer. The Company (or a third party) may make a Change of Control Offer in advance of, and conditioned upon, any Change of Control Triggering Event.

The Company will comply with the requirements of Rule14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Change of Control” provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the “Change of Control” provisions of the Indenture by virtue thereof.

Certain Covenants

The Indenture will contain, among others, the following covenants:

Limitation on liens.    The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or permit or suffer to exist any Liens of any kind against or upon any property or assets of the Company or any of its Restricted Subsidiaries whether owned on the Issue Date or acquired after the Issue Date, or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom unless:

1. in the case of Liens securing Subordinated Indebtedness, the notes are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; and

2. in all other cases, the notes are equally and ratably secured, except for:

(a) Liens securing borrowings under a Bank Facility in an amount not to exceed the greater of (x) $4.4 billion and (y) such amount that at the time of incurrence (or, in the case of Designated Revolving Commitments, on the date such Designated Revolving Commitments are designated as such (but only to the extent and so long as so

S-37

designated) after giving pro forma effect to the incurrence of the entire amount of Indebtedness designated thereunder, in which case such designated amount under such Designated Revolving Commitments may thereafter be borrowed, repaid and reborrowed, in whole or in part, from time to time, without further compliance with any limitations on Liens set forth in this subsection titled “Limitation on Liens”) and after giving pro forma effect to any such Lien and obligations secured thereunder (including the use of proceeds thereof) the Company and its Restricted Subsidiaries shall have a Secured Leverage Ratio less than or equal to 2.25 to 1.0;

(b) Liens existing as of the Issue Date to the extent and in the manner such Liens are in effect on the Issue Date;

(c) Liens securing the Company’s and its Restricted Subsidiaries’ Obligations under any hedge facility permitted under the Indenture to be entered into by the Company and its Restricted Subsidiaries;

(d) Liens securing the notes;

(e) Liens in favor of the Company or a Wholly Owned Restricted Subsidiary of the Company on assets of any Restricted Subsidiary of the Company; and

(f) Permitted Liens.

With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any accrual of interest, whether payable in cash or in kind, accretion or amortization of original issue discount, imputed interest, the payment of interest in the form of additional Indebtedness with the same terms or the payment of dividends on Disqualified Capital Stock in the form of additional shares of the same class, and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness.

Limitation on Sale and Leaseback Transactions.    The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction with respect to any property or assets unless:

1. the Sale and Leaseback Transaction is solely with the Company or a Restricted Subsidiary;

2. the lease is for a period not in excess of 36 months (or which may be terminated by us or any of our subsidiaries within a period of not more than 36 months);

3. we would be able to incur indebtedness secured by a Lien with respect to such Sale and Leaseback Transaction without equally and ratably securing the notes pursuant to the second enumerated item of the “Limitation on Liens” subsection described above; or

4. the Company or such Restricted Subsidiary within 365 days after the sale of such property in connection with such Sale and Leaseback Transaction is completed, applies an amount equal to the net proceeds of the sale of such property to (i) the permanent retirement of Notes, other Indebtedness of the Company ranking on a parity with the Notes in right of payment or Indebtedness of the Company or a Restricted Subsidiary or (ii) the purchase of

S-38

other property;provided that, in lieu of applying such amount to the retirement of Pari Passu Indebtedness, we may deliver notes to the Trustee for cancellation; such notes to be credited at the cost thereof to us.

Consolidation, merger and sale of assets.    The Company will not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or cause or permit any Restricted Subsidiary of the Company to sell, assign, transfer, lease, convey or otherwise dispose of) all or substantially all of the Company’s assets (determined on a consolidated basis for the Company and the Company’s Restricted Subsidiaries) whether as an entirety or substantially as an entirety to any Person unless:

1. either:

(a) the Company shall be the surviving or continuing corporation; or

(b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of the Company and of the Company’s Restricted Subsidiaries substantially as an entirety (the “Surviving Entity”);

(x) shall be an entity organized and validly existing under the laws of the United States or any State thereof or the District of Columbia;provided that in the case where the Surviving Entity is not a corporation, aco-obligor of the notes is a corporation; and

(y) shall expressly assume, by supplemental indenture (in form satisfactory to the Trustee), executed and delivered to the Trustee, the due and punctual payment of the principal of, and premium, if any, and interest on all of the notes and the performance of every covenant of the notes and the Indenture on the part of the Company to be performed or observed;

2. immediately before and immediately after giving effect to such transaction and the assumption contemplated by clause 1(b)(y) above, no Default or Event of Default shall have occurred or be continuing; and

3. the Company or the Surviving Entity shall have delivered to the Trustee an officers’ certificate and an opinion of counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with the applicable provisions of the Indenture and that all conditions precedent in the Indenture relating to such transaction have been satisfied.

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Company, in a single or a series of related transactions, which properties and assets, if held by the Company instead of such Restricted Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

Notwithstanding the foregoing clauses 1 and 2, but subject to the proviso in subclause (x) of clause 1(b), the Company may merge with (a) any of its Wholly Owned Restricted Subsidiaries or

S-39

(b) an Affiliate that is a Person that has no material assets or liabilities and which was organized solely for the purpose of reorganizing the Company in another jurisdiction.

For the avoidance of doubt, nothing in this covenant shall prevent the Company or any Restricted Subsidiary from consummating the Company Conversion.

The Indenture will provide that upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of the Company in accordance with the foregoing in which the Company is not the continuing corporation, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and the notes with the same effect as if such surviving entity had been named as such and all financial information and reports required by the Indenture shall be provided by and for such surviving entity.

Payments for consent.    The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the notes unless such consideration is offered to be paid and is paid to all Holders of the notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Reports to holders.    Whether or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company must provide the Trustee and, upon request, to any Holder of the notes within fifteen (15) business days after filing, or in the event no such filing is required, within fifteen (15) business days after the end of the time periods specified in those sections with:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the United States Securities and Exchange Commission (the “Commission”) on Forms10-Q and10-K if the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual financial statements only, a report thereon by the Company’s certified independent accountants, and

(2) all current reports that would be required to be filed with the Commission on Form8-K if the Company were required to file such reports;

provided that the foregoing delivery requirements shall be deemed satisfied if the foregoing materials are available on the Commission’s EDGAR system or on the Company’s website within the applicable time period.

In addition, whether or not required by the Commission, the Company will, if the Commission will accept the filing, file a copy of all of the information and reports referred to in clauses (1) and (2) with the Commission for public availability within the time periods specified in the Commission’s rules and regulations. In addition, the Company will make the information and reports available to securities analysts and prospective investors upon request. If the Company had any Unrestricted Subsidiaries during the relevant period, the Company will also provide to the Trustee and, upon request, to any Holder of the notes, information sufficient to ascertain the financial condition and results of operations of the Company and its Restricted Subsidiaries, excluding in all respects the Unrestricted Subsidiaries.

S-40

Notwithstanding anything to the contrary herein, the Company will not be deemed to have failed to comply with any of its obligations hereunder for purposes of clause (3) under “—Events of Default” until 90 days after the date any report hereunder is due to be delivered to the Trustee.

Events of Default

The following events are defined in the Indenture as “Events of Default”:

(1) the failure to pay interest on any notes when the same becomes due and payable and the default continues for a period of 30 days;

(2) the failure to pay the principal on any notes, when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer) on the date specified for such payment in the applicable offer to purchase;

(3) a default in the observance or performance of any other covenant or agreement contained in the Indenture which default continues for a period of 60 days after the Company receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the notes (except in the case of a default with respect to the “Merger, consolidation and sale of assets” covenant, which will constitute an Event of Default with such notice requirement but without such passage of time requirement);

(4) the failure to pay at final maturity (giving effect to any applicable grace periods and any extensions thereof) the stated principal amount of any Indebtedness of the Company or any Restricted Subsidiary of the Company, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded, annulled or otherwise cured within 30 days of receipt by the Company or such Restricted Subsidiary of notice of any such acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final stated maturity or which has been so accelerated (in each case with respect to which the30-day period described above has passed), equals $350.0 million or more at any time;

(5) one or more judgments in an aggregate amount in excess of $350.0 million shall have been rendered against the Company or any of its Restricted Subsidiaries and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final andnon-appealable; or

(6) certain events of bankruptcy affecting the Company or any of its Material Subsidiaries.

If an Event of Default (other than an Event of Default specified in clause (6) above with respect to the Company) shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding notes may declare the principal of and accrued interest on all the notes to be due and payable by notice in writing to the Company and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration,” and the same shall become immediately due and payable.

If an Event of Default specified in clause (6) above with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on

S-41

all of the outstanding notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

The Indenture will provide that, at any time after a declaration of acceleration with respect to the notes as described in the preceding paragraphs, the Holders of a majority in principal amount of the notes may rescind and cancel such declaration and its consequences:

1. if the rescission would not conflict with any judgment or decree;

2. if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;

3. to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

4. if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and

5. in the event of the cure or waiver of an Event of Default of the type described in clause (6) of the description above of Events of Default, the Trustee shall have received an officers’ certificate and an opinion of counsel that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

The Holders of a majority in principal amount of the notes may waive any existing Default or Event of Default under the Indenture, and its consequences, except a default in the payment of the principal of or interest on any notes.

Holders of the notes may not enforce the Indenture or the notes except as provided in the Indenture and under the Trust Indenture Act. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee indemnity satisfactory to the Trustee. Subject to all provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

Under the Indenture, the Company is required to provide an officers’ certificate to the Trustee promptly upon any such officer obtaining knowledge of any Default or Event of Default (provided that such officers shall provide such certification at least annually whether or not they know of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof.

No Personal Liability of Directors, Officers, Employees and Stockholders

No past, present or future director, officer, employee, incorporator, agent, stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the notes or under the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of notes by accepting a note waives and releases all such liabilities. The waiver and release are part of the consideration for the issuance of the

S-42

notes. Such waiver may not be effective to waive liabilities under federal securities law, and it is the view of the Commission that such a waiver is against public policy.

Legal Defeasance and Covenant Defeasance

The Company may, at its option and at any time, elect to have its obligations discharged with respect to the outstanding notes (“Legal Defeasance”). Such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding notes, except for:

1. the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the applicable notes when such payments are due;

2. the Company’s obligations with respect to the notes concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payments;

3. the rights, powers, trust, duties and immunities of the Trustee and the Company’s obligations in connection therewith; and

4. the Legal Defeasance provisions of the Indenture.

In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not includingnon-payment, bankruptcy, receivership, reorganization and insolvency events) described under “—Events of Default” will no longer constitute an Event of Default with respect to the notes.

In order to exercise either Legal Defeasance or Covenant Defeasance:

1. the Company must irrevocably deposit with the Trustee (or with a custodian or account bank appointed on behalf of the Trustee), for the benefit of the Holders, cash in euro (or U.S. dollars as described under “—Issuance in Euro”),non-callable European Government Obligations, rated AAA or better by S&P and Aaa by Moody’s, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

2. in the case of Legal Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that:

(a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

(b) since the date of the Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, beneficial owners of the notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

S-43

3. in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that beneficial owners of the notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

4. no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings);

5. such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Indenture (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or any other material agreement or instrument to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound;

6. the Company shall have delivered to the Trustee an officers’ certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others;

7. the Company shall have delivered to the Trustee an officers’ certificate and an opinion of counsel, which opinion may be subject to customary assumptions and exclusions, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with;

8. the Company shall have delivered to the Trustee an opinion of counsel to the effect that assuming no intervening bankruptcy of the Company between the date of deposit and the 124th day following the date of deposit and that no Holder is an insider of the Company, after the 124th day following the date of deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; and

9. certain other customary conditions precedent are satisfied.

Notwithstanding the foregoing, the opinion of counsel required by clause 2 above with respect to a Legal Defeasance need not be delivered if all notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) will become due and payable on the maturity date or a redemption date within one year under arrangements reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

S-44

Satisfaction and Discharge

The Indenture will be discharged and will cease to be of further effect (except as to surviving rights or registration of transfer or exchange of the notes, as expressly provided for in the Indenture) as to all outstanding notes when:

1. either:

(a) all the notes theretofore authenticated and delivered (except lost, stolen or destroyed notes which have been replaced or paid and notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or

(b) all notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) will become due and payable within one year, or are to be called for redemption within one year, under arrangements reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee (or with a custodian or account bank appointed on behalf of the Trustee) funds in an amount in cash in euro (or U.S. dollars as described under “—Issuance in Euro”), European Government Obligations, rated AAA or better by S&P and Aaa by Moody’s, or a combination thereof, sufficient to pay and discharge the entire Indebtedness on the notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the notes to the date of maturity or redemption, as the case may be, together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

2. the Company has paid all other sums payable under the Indenture by the Company with respect to the notes; and

3. the Company has delivered to the Trustee an officers’ certificate and an opinion of counsel, which opinion may be subject to customary assumptions and exclusions, stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

Modification of the Indenture

Except as provided in the next two succeeding paragraphs, the Company and the Trustee with the consent of the holders of at least a majority in aggregate principal amount of the notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the notes) may amend the Indenture or the notes and the holders of at least a majority in aggregate principal amount of the notes outstanding may waive any past default or compliance with any provisions of the Indenture or the notes.

Without the consent of each holder of an outstanding note, no amendment or waiver may:

1. reduce the amount of notes whose Holders must consent to an amendment;

2. reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, on any notes;

S-45

3. reduce the principal of or change or have the effect of changing the fixed maturity of any notes, or change the date on which any notes may be subject to redemption or reduce the redemption price therefor, other than prior to the Company’s obligation to purchase notes under provisions relating to the Company’s obligation to make and consummate a Change of Control Offer in the event of a Change of Control Triggering Event;

4. make any notes payable in money other than that stated in the notes;

5. make any change in provisions of the Indenture protecting the right of each Holder to receive payment of principal of and interest on such note on or after the due date thereof or to bring suit to enforce such payment (except a rescission of acceleration of the notes by the Holders of at least a majority in aggregate principal amount of the notes and a waiver of the payment default that resulted from such acceleration), or permitting Holders of a majority in principal amount of notes to waive Defaults or Events of Default;

6. after the Company’s obligation to purchase notes arises thereunder, amend, change or modify in any material respect the obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control Triggering Event or, after such Change of Control Triggering Event has occurred, modify any of the provisions or definitions with respect thereto;

7. modify or change any provision of the Indenture or the related definitions affecting the ranking of the notes in a manner which adversely affects the Holders;

8. [Reserved]; or

9. modify or change the amendment provisions of the notes or the Indenture.

The Indenture and the notes may be amended by the Company and the Trustee without the consent of any holder of the notes to:

1. cure any ambiguity, defect or inconsistency;

2. provide for the assumption by a Surviving Entity of the obligations of the Company under the Indenture;

3. provide for uncertificated notes in addition to or in place of certificated notes;

4. [Reserved];

5. secure the notes, add to the covenants of the Company for the benefit of the holders of the notes or surrender any right or power conferred upon the Company;

6. make any change that does not adversely affect the rights of any holder of the notes;

7. comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act;

8. provide for the issuance of Additional Notes in accordance with the Indenture;

9. evidence and provide for the acceptance of appointment by a successor Trustee;

S-46

10. conform the text of the Indenture or the notes to any provision of this “Description of Notes” to the extent that such provision in this “Description of Notes” was intended to be a recitation of a provision of the Indenture or the notes; or

11. make any amendment to the provisions of the Indenture relating to the transfer and legending of the notes as permitted by the Indenture, including, without limitation to facilitate the issuance and administration of the notes;provided that (i) compliance with the Indenture as so amended would not result in the notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of Holders to transfer the notes.

The consent of the holders of the notes is not necessary to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

Governing Law

The Indenture will provide that it, the notes will be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby.

The Trustee

The Indenture will provide that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the existence of an Event of Default, the Trustee will exercise such rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

The Indenture and the provisions of the Trust Indenture Act contain certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payments of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. Subject to the Trust Indenture Act, the Trustee will be permitted to engage in other transactions;provided that if the Trustee acquires any conflicting interest as described in the Trust Indenture Act, it must eliminate such conflict or resign.

Board Action

Any action required or permitted to be taken by the Board of Directors of the Company pursuant to the terms of the Indenture may be taken by a duly constituted committee of the Board of Directors of the Company.

Book-Entry System and Form of Notes

The notes will be issued in the form of one or more global notes. The global notes will be deposited with a common depository for the accounts of Euroclear and/or Clearstream and will be registered in the name of the common depository. Ownership of interests in the global notes, referred to as “book-entry interests”, will be limited to persons that have accounts with Clearstream and Euroclear. Book-entry interests will be shown on, and transfers thereof will be

S-47

effected only through, records maintained in book-entry form by Euroclear and/or Clearstream and its participants. The terms of the Indenture will provide for the issuance of definitive registered notes in certain circumstances.

Material U.S. Federal Income Tax Consequences

The following are the material U.S. federal income tax consequences of ownership and disposition of the notes. This discussion applies only to notes that are:

• held by those initial investors who purchased such notes in this offering at the “issue price,” which will equal the first price to the public (not including bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) at which a substantial amount of the notes is sold for money; and

• held as capital assets for U.S. federal income tax purposes.

This discussion does not describe all of the tax consequences that may be relevant to investors in light of their particular circumstances, including alternative minimum tax or Medicare contribution tax consequences, or tax consequences applicable to investors subject to special rules, such as:

• certain financial institutions;

• insurance companies;

• dealers in securities;

• persons holding notes as part of a hedge, “straddle,” integrated transaction or similar transaction;

• U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

• persons required for U.S. federal income tax purposes to conform the timing of income accruals with respect to the notes to their financial statements under Section 451 of the Internal Revenue Code of 1986, as amended (the “Code”);

• partnerships or other entities classified as partnerships for U.S. federal income tax purposes; or

• tax-exempt entities.

If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds notes, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding notes and partners in such partnerships should consult their own tax advisors as to their particular U.S. federal income tax consequences of holding and disposing of the notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein. Persons considering the purchase of notes are urged to consult their own tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Tax Consequences to U.S. Holders

As used herein, the term “U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

• an individual citizen or resident of the United States;

S-64

• a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state thereof or the District of Columbia; or

• an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

The term “U.S. Holder” also includes certain former citizens and residents of the United States.

Potential contingent payment debt treatment.    Under certain circumstances, Equinix may pay amounts in excess of the stated interest and principal payable on the notes. For instance, Equinix would be required to offer to repurchase notes in the circumstances described under “Description of Notes—Change of Control Triggering Event.” Although the issue is not free from doubt, Equinix intends to take the position that the possibility of such payments does not result in the notes being treated as contingent payment debt instruments under the applicable Treasury Regulations. Equinix’s position is not binding on the Internal Revenue Service (the “IRS”). If the IRS successfully takes a contrary position, U.S. Holders would be required to treat any gain recognized on the sale or other disposition of the notes as ordinary income rather than as capital gain. Furthermore, U.S. Holders would be required to accrue interest income on a constant-yield basis at an assumed yield determined at the time of issuance of the notes, with adjustments to such accruals when any contingent payments are made that differ from the payments calculated based on the assumed yield. U.S. Holders should consult their own tax advisors regarding the tax consequences of the notes being treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

Payments of interest.    Stated interest paid on a note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. Holder’s method of accounting for U.S. federal income tax purposes. It is expected, and therefore this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes.

A U.S. Holder that uses the cash method of tax accounting and that receives a payment of interest (or receives proceeds from a sale, exchange or other disposition attributable to accrued interest) in euro will be required to include in income the U.S. dollar value of the euro payment (determined based on the spot rate on the date the payment is received), and this U.S. dollar value will be the U.S. Holder’s tax basis in the euro received.

A U.S. Holder that uses the accrual method of tax accounting will be required to include in income the U.S. dollar value of the amount of interest income that accrues with respect to a note during an accrual period. The U.S. dollar value of the accrued income will generally be determined by translating the income at the average rate of exchange for the accrual period or, with respect to an accrual period that spans two taxable years, at the average rate for the partial period within the taxable year. A U.S. Holder that uses the accrual method of tax accounting may elect to translate interest income for an interest accrual period into U.S. dollars at the spot rate on the last day of the interest accrual period (or, in the case of a partial accrual period, the spot rate on the last day of the taxable year) or, if the date of receipt is within five business days of the last day of the interest accrual period, the spot rate on the date of receipt. A U.S. Holder that makes this election must apply it consistently to all debt instruments from year to year and cannot change the election without the consent of the IRS. An accrual method U.S. Holder will generally recognize foreign currency gain or loss (which will be treated as ordinary income or

S-65

loss) with respect to accrued interest income on the date the interest payment (or proceeds from a sale, exchange or other disposition attributable to accrued interest) is actually received. The amount of ordinary income or loss recognized will generally equal the difference between the U.S. dollar value of the euro payment received (determined based on a spot rate on the date the payment is received) in respect of the accrual period and the U.S. dollar value of interest income that has accrued during the accrual period (as determined above). The U.S. Holder’s tax basis in the euro received will generally equal its U.S. dollar value based on the spot rate on the date the payment is received. As discussed below under “—Sale, exchange, redemption, retirement or other disposition of the notes,” the amount of foreign currency gain or loss recognized with respect to accrued but unpaid interest upon a taxable disposition of a note may be limited by the total amount of gain or loss realized upon such disposition.

Sale, exchange, redemption, retirement or other disposition of the notes.    A U.S. Holder’s tax basis in a note will generally be the U.S. dollar value of the euro amount paid for the note, determined on the date of the purchase. A U.S. Holder who purchases a note with previously owned euro will generally recognize ordinary income or loss in an amount equal to the difference, if any, between such U.S. Holder’s tax basis in the euro and the U.S. dollar value of the note on the date of purchase. If the notes are traded on an established securities market (as determined under applicable regulations), a cash method taxpayer who buys a note will have a tax basis in the note equal to the U.S. dollar value of the euro amount paid for the note, determined on the settlement date, and such a taxpayer will recognize ordinary income or loss on any previously purchased euro based on such value. An accrual method taxpayer may elect the same treatment for all purchases (and sales, as discussed below) of notes traded on an established securities market. This election by accrual method taxpayers cannot be changed without the consent of the IRS.

Upon the sale, exchange, redemption, retirement or other disposition of a note, a U.S. Holder will generally recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange, redemption, retirement or other disposition of the note and the U.S. Holder’s tax basis in the note. For these purposes, the amount realized does not include any amount attributable to accrued stated interest. Amounts attributable to accrued stated interest are treated as interest as described under “—Payments of interest” above. If a note is sold, exchanged or otherwise disposed of in a taxable transaction for an amount denominated in euro, a U.S. Holder’s amount realized generally will equal the U.S. dollar value of the euro received in the sale, exchange or other taxable disposition calculated at the exchange rate in effect on the date of the disposition. If the notes are traded on an established securities market (as determined under applicable regulations), a cash method taxpayer who buys or sells a note is required to translate units of euro paid or received into U.S. dollars at the spot rate on the settlement date of the purchase or sale and an accrual method taxpayer may elect the same treatment for all purchases and sales of notes. This election by accrual method taxpayers cannot be changed without the consent of the IRS. Except to the extent of foreign currency gain or loss (as described below), gain or loss realized on the sale, exchange, redemption, retirement or other disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the sale, exchange, redemption, retirement or disposition the note has been held for more than one year. Long-term capital gains recognized bynon-corporate U.S. Holders are subject to reduced tax rates. The deductibility of capital losses may be subject to limitations.

A U.S. Holder may recognize foreign currency gain or loss upon the sale, exchange, redemption, retirement or other disposition of a note as a result of fluctuations in theeuro-U.S. dollar

S-66

exchange rate. Gain or loss attributable to such fluctuations will equal the difference between (i) the U.S. dollar value of the U.S. Holder’s purchase price in euro of the note, determined using the spot rate on the date the note is disposed of, and (ii) the U.S. dollar value of the U.S. Holder’s purchase price in euro of the note, determined using the spot rate on the date the U.S. Holder acquired the note (or, possibly, in the case of cash method or electing accrual method taxpayers, the settlement dates of such disposition and purchase, if the note is treated as traded on an established securities market as discussed above). The foreign currency gain or loss (together with any foreign currency gain or loss with respect to accrued but unpaid interest) will be recognized only to the extent of the total gain or loss realized by a U.S. Holder on the sale, exchange, redemption, retirement or other disposition of the note. Any such gain or loss generally will be ordinary income or loss. If a U.S. Holder recognizes a loss upon a sale, exchange, redemption, retirement or other disposition of a note and such loss is above certain thresholds (which thresholds are, in the case of individuals and trusts, significantly lower for foreign currency losses than for other loss transactions), the U.S. Holder may be required to file a disclosure statement with the IRS. U.S. Holders should consult their own tax advisors regarding this reporting obligation.

A U.S. Holder will have a tax basis in any euro received on the sale, exchange, redemption, retirement or other disposition of a note equal to the U.S. dollar value of the euro, determined on the date of receipt of the euro. If a U.S. Holder purchases euros and uses the euros to acquire notes, the tax basis of the euros will generally be the U.S. dollar value of the euros on the date of purchase. Any gain or loss realized by a U.S. Holder on a sale, exchange, redemption, retirement or other disposition of euro (including its exchange for U.S. dollars) will generally be treated as ordinary income or loss.

Backup withholding and information reporting.    Information returns will generally be filed with the IRS in connection with payments on the notes and the proceeds from a sale, exchange, redemption, retirement or other disposition of the notes. A U.S. Holder will be subject to backup withholding on these payments if the U.S. Holder fails to timely provide its taxpayer identification number to the applicable withholding agent and comply with certain certification procedures or otherwise establish an exemption from backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Tax Consequences toNon-U.S. Holders

As used herein, the term“Non-U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

• a nonresident alien individual;

• a foreign corporation; or

• a foreign estate or trust.

“Non-U.S. Holder” does not include a nonresident alien individual present in the United States for 183 days or more in the taxable year of disposition of the notes. Such a beneficial owner is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the sale, exchange or other disposition of the notes.

S-67

Potential contingent payment debt treatment.    As described in more detail above under “Tax Consequences to U.S. Holders—Potential contingent payment debt treatment,” Equinix intends to take the position that the possibility of making payments in excess of the stated interest and principal payable on the notes under certain circumstances does not result in the notes being treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

Payments on the notes.    Subject to the discussions below concerning backup withholding and FATCA, payments of principal, interest and premium (if any) on the notes by Equinix or any paying agent to aNon-U.S. Holder will not be subject to U.S. federal withholding tax, provided that, in the case of interest,

• theNon-U.S. Holder does not own, actually or constructively, 10 percent or more of the total combined voting power of all classes of stock of Equinix entitled to vote and is not a controlled foreign corporation related, directly or indirectly, to Equinix through stock ownership; and

• theNon-U.S. Holder certifies on a properly executed IRS FormW-8BEN or FormW8BEN-E, under penalties of perjury, that it is not a United States person.

If aNon-U.S. Holder cannot satisfy one of the requirements described above and interest on the notes is not exempt from withholding because it is effectively connected with theNon-U.S. Holder’s conduct of a trade or business in the United States as described below, payments of interest on the notes will be subject to withholding tax at a rate of 30%, or the rate specified by an applicable treaty.

If aNon-U.S. Holder of a note is engaged in a trade or business in the United States, and if interest on the note is effectively connected with the conduct of this trade or business, theNon-U.S. Holder, although exempt from the withholding tax discussed in the preceding paragraph, will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above), except that theNon-U.S. Holder will be required to provide a properly executed IRS FormW-8ECI in order to claim an exemption from the withholding tax discussed in the preceding paragraph.Non-U.S. Holders are urged to consult their own tax advisors regarding any different tax consequences if an applicable income tax treaty applies and regarding other U.S.    tax consequences of the ownership and disposition of notes, including the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate) on its effectively connected earnings and profits attributable to its notes.

Sale, exchange or other disposition of notes.    Subject to the discussions below under “—Backup withholding and information reporting” and “FATCA,” aNon-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on gain recognized on a sale or other disposition of notes (other than with respect to amounts attributable to accrued interest which will be subject to tax in the manner described above), unless the gain is effectively connected with the conduct of a trade or business of theNon-U.S. Holder in the United States, subject to an applicable income tax treaty providing otherwise.

If aNon-U.S. Holder is engaged in a trade or business in the United States and gain recognized by theNon-U.S. Holder on a sale or other disposition of notes is effectively connected with a conduct of such trade or business, theNon-U.S. Holder will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above), subject to an applicable income tax treaty providing otherwise.Non-U.S. Holders whose gain from dispositions of notes may be effectively connected with the conduct of a trade or business in the United States are

S-68

urged to consult their own tax advisors with respect to the U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of an additional branch profits tax imposed at a rate of 30% (or a lower treaty rate).

Backup withholding and information reporting.    Information returns will be filed with the IRS in connection with payments on the notes. Unless theNon-U.S. Holder complies with certification procedures to establish that it is not a United States person, information returns may be filed with the IRS in connection with the proceeds from a sale or other disposition of the notes and theNon-U.S. Holder may be subject to backup withholding on payments on the notes or on the proceeds from a sale or other disposition of the notes. Compliance with the certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. The amount of any backup withholding from a payment to aNon-U.S. Holder will be allowed as a credit against theNon-U.S. Holder’s U.S. federal income tax liability and may entitle theNon-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

FATCA

Provisions commonly referred to as “FATCA” impose U.S. federal withholding of 30% on payments of interest on the notes and, for dispositions after December 31, 2018, gross proceeds from the disposition of the notes to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain othernon-U.S. entities (whether such foreign financial institutions or othernon-U.S. entities are beneficial owners or intermediaries) unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). Prospective investors should consult their own tax advisors regarding the effects of FATCA on their investment in the notes.

Underwriting

We are offering the notes described in this prospectus supplement through a number of underwriters. Barclays Bank plc, HSBC Securities (USA) Inc. and ING Bank N.V., London Branch, are acting as representatives of the underwriters. We have entered into an underwriting agreement with the underwriters as of the date of this prospectus supplement. Subject to the terms and conditions in the underwriting agreement between us and the underwriters, we have agreed to sell to each underwriter, and each underwriter has agreed to purchase from us, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the principal amount of notes set forth opposite that underwriter’s name:

The obligations of the underwriters under the underwriting agreement, including their agreement to purchase notes from us, are several and not joint. The underwriting agreement provides that the underwriters have agreed to purchase all of the notes if any of them are purchased.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to    % of the principal amount. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates. The underwriters may also offer and sell notes in the United States through one of more of their respective affiliates or through United States-registered broker dealers. Certain of the underwriters are not registered broker-dealers in the United States, and therefore, to the extent that they intend to effect any offers or sales of the notes in the United States, they will do

S-70

so through one or more U.S. registered broker-dealers pursuant to applicable U.S. securities laws and regulations.

In the underwriting agreement, we have agreed that:

• we will not offer or sell any of our debt securities (other than the notes offered pursuant to this prospectus supplement and the notes to be issued in connection with the proposed acquisition of the Infomart) for a period of 45 days after the initial issue date of the notes without the prior consent of Barclays Bank plc, HSBC Securities (USA) Inc. and ING Bank N.V., London Branch; and

• we will indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

It is expected that delivery of the notes will be made against payment therefor on or about            , 2018, which is the tenth business day following the date of pricing of the notes (such settlement cycle being referred to as “T+10”). Under Rule15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise.

Accordingly, purchasers who wish to trade the notes on the date of pricing or the next succeeding seven business days will be required, by virtue of the fact that the notes initially will settle in T+10, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.

Discounts and Commissions

The following table shows the underwriting discounts and commissions to be paid by us to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

	Paid by us
Per note		%

We estimate that the expenses for this offering payable by us (other than the underwriting discounts and commissions set forth in the table above) will be approximately $2.3 million. The underwriters have agreed to reimburse us for certain expenses relating to this offering.

New Issue of Notes

The notes are a new issue of securities with no established trading market. We will apply, following the completion of this offering, to have the notes listed on the Exchange and admitted for trading on the Official List of the Exchange on or prior to the first interest payment date.

However, no assurance can be given that the notes will become or will remain listed. If such listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time. Beyond the foregoing, we do not intend to apply to list the notes on any securities exchange or to arrange for the notes to be quoted on any quotation system.

The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so and they may discontinue any market making at any time in their sole

discretion. Accordingly, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

In connection with this offering of the notes, HSBC Securities (USA) Inc. (or one or more of its affiliates), as stabilizing manager (the “Stabilizing Manager”), (or persons acting on behalf of the Stabilizing Manager) may over-allot or effect transactions which stabilize or maintain the market price of the notes at levels which might not otherwise prevail. This stabilizing, if commenced, may be discontinued at any time. There is no assurance that the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) will undertake any stabilization action. Any stabilization action may begin on or after the date on which adequate public disclosure of the terms of the offer of the notes is made and, if begun, may be ended at any time, but it must end no later than the earlier of 30 days after the issue date of the notes and 60 days after the date of the allotment of the notes. Any stabilization action or over-allotment must be conducted by the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) in accordance with all applicable laws and rules.

Other Relationships

The underwriters and their respective affiliates are full-service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, market making, financing and brokerage activities.

Certain of the underwriters and their affiliates have performed commercial banking, investment banking and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses. Certain affiliates of the underwriters act as lenders and/or agents under our existing credit facilities. Affiliates of U.S. Bancorp Investments, Inc. are acting as Trustee, paying agent and Registrar for the notes and will receive customary fees and expenses in connection therewith. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. Certain of the underwriters or their affiliates are customers of ours and engage in transactions with us or our affiliates in the ordinary course of business.

Certain of the underwriters or their affiliates have lending relationships with us. Certain of those underwriters or their affiliates routinely hedge, certain of those underwriters or their affiliates are likely to hedge and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future. In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans)

S-72

for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the Company. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

We have not authorized and do not authorize the making of any offer of notes through any financial intermediary on our behalf, other than offers made by the underwriters with a view to the final placement of the notes as contemplated in this prospectus. Accordingly, no purchaser of the notes, other than the underwriters, is authorized to make any further offer of the notes on behalf of us or the underwriters.

You should be aware that the laws and practices of certain countries require investors to pay stamp taxes and other charges in connection with purchases of securities.

PRIIPs Regulation; Prohibition of Sales to EEA Retail Investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the European Economic Area has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the European Economic Area may be unlawful under the PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of notes in any Member State of the European Economic Area will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes.

The Company has not and will not register with the Swiss Financial Market Supervisory Authority (“FINMA”) as a foreign collective investment scheme pursuant to Article 119 of the Federal Act on Collective Investment Scheme of 23 June 2006, as amended (“CISA”), and accordingly the notes being offered pursuant to this prospectus supplement have not and will not be approved, and may not be licenseable, with FINMA. Therefore, the notes have not been authorized for distribution by FINMA as a foreign collective investment scheme pursuant to Article 119 CISA and the notes offered hereby may not be offered to the public (as this term is defined in Article 3 CISA) in or from Switzerland.

RISK FACTORS

An investment in our securities involves significant risks. Before purchasing any securities, you should carefully consider and evaluate all of the information included and incorporated by reference or deemed to be incorporated by reference in this prospectus or the applicable prospectus supplement, including the risk factors incorporated by reference herein from our Annual Report on Form10-K for the year ended December 31, 2016, as updated by annual, quarterly and other reports and documents we file with the SEC after the date of this prospectus and that are incorporated by reference herein or in the applicable prospectus supplement. Our business, results of operations or financial condition could be adversely affected by any of these risks or by additional risks and uncertainties not currently known to us or that we currently consider immaterial.

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, the net proceeds from the sale of the securities will be used for general corporate purposes, including working capital, acquisitions, retirement of debt and other business opportunities.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our consolidated ratio of earnings to fixed charges:

Nine Months Ended

Years Ended

September 30, 2017

December 31, 2016

December 31, 2015

December 31, 2014

Ratio of earnings to fixed charges

1.4x

1.3x

1.6x

1.2x

1.4x

1.6x

In calculating the ratio of earnings to fixed charges, earnings consist of net income (loss) from continuing operations before income tax expense and fixed charges. Fixed charges consist of interest expense, including such portion of rental expense that was attributed to interest, and amortization of capitalized interest. The portion of rent expense that was attributed to interest represents a reasonable approximation of the interest factor. We have not included a ratio of earnings to combined fixed charges and preferred stock dividends because we do not have any preferred stock outstanding as of the date of this prospectus.

DESCRIPTION OF CAPITAL STOCK

The following summary of the terms of our capital stock is not meant to be complete and is qualified by reference to the relevant provisions of the Delaware General Corporation Law (the “DGCL”) and our amended and restated certificate of incorporation (our “certificate of incorporation”) and our amended and restated bylaws (our “bylaws”). Our certificate of incorporation and bylaws are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part. See “Where You Can Find More Information” above.

Authorized Capital Stock

Under our certificate of incorporation, our authorized capital stock consists of 300,000,000 shares of common stock, par value $0.001 per share, and 100,000,000 shares of preferred stock, $0.001 par value per share. At September 30, 2017, there were issued and outstanding:

• 78,233,670 shares of our common stock (not counting shares held in treasury);

3

• employee restricted stock units for an aggregate of 1,318,587 shares of our common stock;

• employee stock options to purchase an aggregate of 6,896 shares of our common stock; and

• zero shares of our preferred stock.

Common Stock

The holders of our common stock are entitled to one vote per share on all matters to be voted on by the stockholders. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the board of directors out of funds legally available for the payment of dividends. All dividends arenon-cumulative. In the event of the liquidation, dissolution or winding up of Equinix, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. Our common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of our common stock are fully paid and nonassessable.

Our common stock is listed on the NASDAQ Global Select Market under the symbol “EQIX.”

Preferred Stock

Preferred stock may be issued from time to time in one or more series, each of which is to have the voting powers, designation, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof as are stated and expressed in our certificate of incorporation, or in a resolution or resolutions providing for the issue of that series adopted by our board of directors.

Our board of directors has the authority, without stockholder approval, to create one or more series of preferred stock and, with respect to each series, to fix or alter as permitted by law, among other things, the number of shares of the series and the designation thereof, dividend rights, dividend rate, conversion rights, voting rights, rights and terms of any redemption, redemption price or prices and liquidation preferences.

When we or the selling securityholders offer to sell a particular series of preferred stock, we will describe the specific terms of the securities in a supplement to this prospectus. The preferred stock will be issued under a certificate of designations relating to each series of preferred stock and is also subject to our certificate of incorporation.

The transfer agent for each series of preferred stock will be described in the prospectus supplement.

Restrictions on Ownership and Transfer

To facilitate compliance with the ownership limitations applicable to a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), our certificate of incorporation contains restrictions on the ownership and transfer of our capital stock.

These ownership and transfer restrictions could delay, defer or prevent a transaction or a change in control that might involve a premium price for our common stock or that our stockholders might otherwise deem to be in their best interests.

For us to qualify for taxation as a REIT under the Code, our capital stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months or during a proportionate part of a shorter taxable year. Also, not more than 50% of the value of the outstanding shares of our capital stock may be owned, directly or indirectly, by five or fewer “individuals” (as defined in the Code to include certain entities such as

4

private foundations) during the last half of a taxable year. To facilitate compliance with these ownership requirements and other requirements for continued qualification as a REIT and to otherwise protect us from the consequences of a concentration of ownership among our stockholders, our certificate of incorporation contains provisions restricting the ownership or transfer of shares of capital stock.

The relevant sections of our certificate of incorporation provide that, subject to the exceptions and the constructive ownership rules described below, no person (as defined in our certificate of incorporation) may beneficially or constructively own more than 9.8% in value of the aggregate of outstanding shares of capital stock, including common stock and preferred stock, or more than 9.8% in value or number (whichever is more restrictive) of the outstanding shares of any class or series of capital stock. We refer to these restrictions as the “ownership limits.”

The applicable constructive ownership rules under the Code are complex and may cause capital stock owned actually or constructively by an individual or entity to be treated as owned by another individual or entity. As a result, the acquisition of less than 9.8% in value of outstanding capital stock or less than 9.8% in value or number of outstanding shares of any class or series of capital stock (including through the acquisition of an interest in an entity that owns, actually or constructively, any class or series of capital stock) by an individual or entity could nevertheless cause that individual or entity, or another individual or entity, to own, constructively or beneficially, in excess of 9.8% in value of outstanding capital stock or 9.8% in value or number of outstanding shares of any class or series of capital stock.

In addition to the ownership limits, our certificate of incorporation prohibits any person from actually or constructively owning shares of capital stock to the extent that such ownership would cause any of our income that would otherwise qualify as “rents from real property” for purposes of Section 856(d) of the Code to fail to qualify as such.

Our board of directors has in the past granted ownership limitation waivers and may, in its sole discretion, in the future grant such a waiver to a person exempting them from the ownership limits and certain other REIT limits on ownership and transfer of capital stock described above, and may establish a different limit on ownership for any such person. However, our board of directors may not exempt any person whose ownership of outstanding capital stock in violation of these limits would result in our failing to qualify as a REIT. In order to be considered by our board of directors for an ownership limitation waiver or a different limit on ownership, a person must make such representations and undertakings as are reasonably necessary to ascertain that such person’s beneficial or constructive ownership of capital stock will not now or in the future jeopardize our ability to qualify as a REIT under the Code and must generally agree that any violation or attempted violation of such representations or undertakings (or other action that is contrary to the ownership limits and certain other REIT limits on ownership and transfer of capital stock described above) will result in the shares of capital stock being automatically transferred to a trust as described below. As a condition of its waiver, our board of directors may require an opinion of counsel or Internal Revenue Service ruling satisfactory to our board of directors with respect to our qualification as a REIT and may impose such other conditions as it deems appropriate in connection with the granting of the waiver or a different limit on ownership.

In connection with the waiver of the ownership limits or at any other time, our board of directors may from time to time increase the ownership limits for one or more persons and decrease the ownership limits for all other persons; provided that the new ownership limits may not, after giving effect to such increase and under certain assumptions stated in our certificate of incorporation, result in us being “closely held” within the meaning of Section 856(h) of the Code (without regard to whether the ownership interests are held during the last half of a taxable year). Reduced ownership limits will not apply to any person whose percentage ownership of total shares of capital stock or of the shares of a class or series of capital stock, as applicable, is in excess of such decreased ownership limits until such time as such person’s percentage of total shares of capital stock or of the shares of a class or series of capital stock, as applicable, equals or falls below the decreased ownership limits, but any further acquisition of capital stock in excess of such percentage will be in violation of the ownership limits.

5

Our certificate of incorporation further prohibits:

• any person from transferring shares of capital stock if such transfer would result in shares of capital stock being beneficially owned by fewer than 100 persons (determined without reference to any rules of attribution); and

• any person from beneficially or constructively owning shares of capital stock if such ownership would result in our failing to qualify as a REIT.

The foregoing provisions on transferability and ownership will not apply if our board of directors determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a REIT.

Any person who acquires or attempts or intends to acquire beneficial or constructive ownership of shares of capital stock that will or may violate the ownership limits or any of the other foregoing restrictions on transferability and ownership will be required to give notice to us immediately (or, in the case of a proposed or attempted transaction, at least 15 days prior to such transaction) and provide us with such other information as we may request in order to determine the effect, if any, of such transfer on our qualification as a REIT.

Pursuant to our certificate of incorporation, if there is any purported transfer of our capital stock or other event or change of circumstances that, if effective or otherwise, would violate any of the restrictions described above, then the number of shares causing the violation (rounded up to the nearest whole share) will be automatically transferred to a trust for the exclusive benefit of a designated charitable beneficiary, except that any transfer that results in the violation of the restriction relating to our capital stock being beneficially owned by fewer than 100 persons will be automatically void and of no force or effect. The automatic transfer will be effective as of the close of business on the business day prior to the date of the purported transfer or other event or change of circumstances that requires the transfer to the trust. We refer below to the person that would have owned the shares if they had not been transferred to the trust as the purported transferee. Any ordinary dividend paid to the purported transferee, prior to our discovery that the shares had been automatically transferred to a trust as described above, must be repaid to a trustee designated in accordance with the certificate of incorporation upon demand. Our certificate of incorporation also provides for adjustments to the entitlement to receive extraordinary dividends and other distributions as between the purported transferee and the trust. If the transfer to the trust as described above is not automatically effective, for any reason, to prevent violation of the applicable restriction contained in our certificate of incorporation, then the transfer of the excess shares will be automatically void and of no force or effect.

Shares of our capital stock transferred to the trustee are deemed to be offered for sale to us or our designee at a price per share equal to the lesser of (i) the price per share in the transaction that resulted in such transfer to the trust or, if the purported transferee did not give value for the shares in connection with the event causing the shares to be held in trust (e.g., in the case of a gift, devise or other such transaction), the market price at the time of such event and (ii) the market price on the date we accept, or our designee accepts, such offer. We have the right to accept such offer until the trustee has sold the shares of our capital stock held in the trust pursuant to the clauses described below. Upon a sale to us, the interest of the charitable beneficiary in the shares sold terminates and the trustee must distribute the net proceeds of the sale to the purported transferee, except that the trustee may reduce the amount payable to the purported transferee by the amount of any ordinary dividends that we paid to the purported transferee prior to our discovery that the shares had been transferred to the trust and that is owed by the purported transferee to the trustee as described above. Any net sales proceeds and extraordinary dividends in excess of the amount payable to the purported transferee shall be immediately paid to the charitable beneficiary, and any ordinary dividends held by the trustee with respect to such capital stock will be promptly paid to the charitable beneficiary.

If we do not buy the shares, the trustee must, as soon as reasonably practicable (and, if the shares are listed on a national securities exchange, within 20 days) after receiving notice from us of the transfer of shares to the trust, sell the shares to a person or entity who could own the shares without violating the restrictions described above. Upon such a sale, the trustee must distribute to the purported transferee an amount equal to the lesser of (i) the

6

price paid by the purported transferee for the shares or, if the purported transferee did not give value for the shares in connection with the event causing the shares to be held in trust (e.g., in the case of a gift, devise or other such transaction), the market price of the shares on the day of the event causing the shares to be held in the trust, and (ii) the sales proceeds (net of commissions and other expenses of sale) received by the trustee for the shares. The trustee may reduce the amount payable to the purported transferee by the amount of any ordinary dividends that we paid to the purported transferee before our discovery that the shares had been transferred to the trust and that is owed by the purported transferee to the trustee as described above. Any net sales proceeds in excess of the amount payable to the purported transferee will be immediately paid to the charitable beneficiary, together with any ordinary dividends held by the trustee with respect to such capital stock. In addition, if prior to discovery by us that shares of our capital stock have been transferred to a trust, such shares of capital stock are sold by a purported transferee, then such shares will be deemed to have been sold on behalf of the trust and, to the extent that the purported transferee received an amount for or in respect of such shares that exceeds the amount that such purported transferee was entitled to receive as described above, such excess amount shall be paid to the trustee upon demand. The purported transferee has no rights in the shares held by the trustee.

The trustee will be indemnified by us or from the proceeds of sales of capital stock in the trust for its costs and expenses reasonably incurred in connection with conducting its duties and satisfying its obligations under our certificate of incorporation. The trustee will also be entitled to reasonable compensation for services provided as determined by agreement between the trustee and the board of directors, which compensation may be funded by us or the trust. If we pay any such indemnification or compensation, we are entitled on a first priority basis (subject to the trustee’s indemnification and compensation rights) to be reimbursed from the trust. To the extent the trust funds any such indemnification and compensation, the amounts available for payment to a purported transferee (or the charitable beneficiary) would be reduced.

The trustee will be designated by us and must be unaffiliated with us and with any purported transferee. Prior to the sale of any shares by the trust, the trustee will receive, in trust for the beneficiary, all distributions paid by us with respect to the shares, and may also exercise all voting rights with respect to the shares.

Subject to the DGCL, effective as of the date that the shares have been transferred to the trust, the trustee will have the authority, at the trustee’s sole discretion:

• to rescind as void any vote cast by a purported transferee prior to our discovery that the shares have been transferred to the trust; and

• to recast the vote in accordance with the desires of the trustee acting for the benefit of the charitable beneficiary of the trust.

However, if we have already taken corporate action, then the trustee may not rescind and recast the vote.

In addition, if the board of directors determines that a proposed or purported transfer would violate the restrictions on ownership and transfer of our capital stock set forth in our certificate of incorporation, the board of directors may take such action as it deems advisable to refuse to give effect to or to prevent such violation, including but not limited to, causing us to repurchase shares of our capital stock, refusing to give effect to the transfer on our books or instituting proceedings to enjoin the transfer.

From time to time, at our request, every person that is an owner of 5% or more (or such lower percentage as required by the Code or the Treasury regulations thereunder) of the outstanding shares of any class or series of our capital stock, must provide us written notice of its name and address, the number of shares of each class and series of our capital stock that the person beneficially owns and a description of the manner in which the shares are held. Each such owner must also provide us with such additional information as we may request in order to determine the effect, if any, of such owner’s beneficial ownership on our qualification as a REIT and to ensure compliance with the ownership limits. In addition, each beneficial owner or constructive owner of our capital stock, and any person (including the stockholder of record) who is holding shares of our capital stock for a beneficial owner or constructive owner will, upon demand, be required to provide us with such information as we

7

may request in good faith in order to determine our qualification as a REIT and to comply with the requirements of any taxing authority or governmental authority or to determine such compliance.

Anti-Takeover Effects of Provisions of Our Certificate of Incorporation, Bylaws and Delaware law

Provisions of our certificate of incorporation and bylaws may delay or discourage transactions involving an actual or potential change in control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock.

Among other things, our certificate of incorporation and bylaws:

• permit our board of directors to issue up to 100,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate;

• provide that, subject to the terms of any series of preferred stock, the authorized number of directors may be changed only by resolution of the board of directors;

• provide that, subject to the terms of any series of preferred stock, all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;

• eliminate the personal liability of our directors for monetary damages resulting from breaches of their fiduciary duty to the extent permitted by the DGCL and indemnify our directors and officers to the fullest extent permitted by the DGCL;

• provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner, and also specify requirements as to the form and content of a stockholder’s notice;

• do not provide for cumulative voting rights, therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose;

• provide that, subject to exceptions, certain waivers we may grant and constructive ownership rules, no person may own, or be deemed to own by virtue of the attribution provisions of the Code, in excess of (i) 9.8% in value of the outstanding shares of all classes or series of Equinix stock or (ii) 9.8% in value or number (whichever is more restrictive) of the outstanding shares of any class or series of Equinix stock (as described above in “Restrictions on Ownership and Transfer”);

• provide that our bylaws can be amended or repealed at any regular or special meeting of stockholders or by the board of directors;

• permit stockholders to act by written consent so long as stockholders holding at least 25% of the voting power of the outstanding capital stock request that the board of directors set a record date for the action by written consent, and in connection with such a request for the establishment of a record date, provide certain information, make certain representations and comply with certain requirements relating to the proposed action and their ownership of our stock; and

• provide that special meetings of our stockholders may be called in limited circumstances. Special meetings of stockholders may be called by our board of directors or the chairman of the board of directors, the President or the Secretary and may not be called by any other person. A special meeting of stockholders shall be called by our Secretary at the written request of holders of record of at least 25% of the voting power of our outstanding capital stock entitled to vote on the matters to be brought before the proposed special meeting.

Delaware Takeover Statute. We are subject to Section 203 of the DGCL, which regulates corporate acquisitions. DGCL Section 203 restricts the ability of certain Delaware corporations, including those whose securities are

8

listed on the NASDAQ Global Select Market, from engaging under certain circumstances in a business combination with any interested stockholder for three years following the date that such stockholder became an interested stockholder. For purposes of DGCL Section 203, a business combination includes, among other things, a merger or consolidation involving us and the interested stockholder and the sale of 10% or more of our assets. In general, DGCL Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person. A Delaware corporation may opt out of DGCL Section 203 with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from amendments approved by the holders of at least a majority of the corporation’s outstanding voting shares. We have not opted out of the provisions of DGCL Section 203 in our certificate of incorporation or bylaws.

Forum Selection

Our bylaws include a forum selection provision providing that, unless the Company consents in writing, a state court located in the State of Delaware (or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) will be the sole and exclusive forum for any stockholder to bring any derivative action, any action asserting a claim of breach of fiduciary duties, any action asserting a claim arising from a provision of the Delaware General Corporation Law or the certificate of incorporation or our bylaws or any action asserting a claim governed by the internal affairs doctrine.

Transfer Agent and Registrar

The transfer agent and registrar for the shares of our common stock is Computershare Trust Company, N.A.

DESCRIPTION OF DEBT SECURITIES

Any debt securities we may issue will constitute either senior or subordinated debt of Equinix. Any debt securities that are sold may be exchangeable for and/or convertible into common stock or any of the other securities that may be sold under this prospectus. Any debt securities will be issued under an indenture between us and U.S. Bank National Association, as trustee, or one or more separate indentures between us and a designated trustee. We will include in a prospectus supplement the specific terms of each series of senior or subordinated debt securities being offered, including the terms, if any, on which a series of senior or subordinated debt securities may be convertible into or exchangeable for other securities. In addition, the material terms of any indenture, which will govern the rights of the holders of our senior or subordinated debt securities, will be set forth in the applicable prospectus supplement.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of:

• debt or equity securities issued by us or securities of third parties, a basket of such securities, an index or indices of such securities or any combination of the above as specified in the applicable prospectus supplement;

9

• currencies; or

• commodities.

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

Any purchase contracts we may issue may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle suchpre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly,pre-paid purchase contracts will be issued under an indenture.

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, we may issue units consisting of one or more purchase contracts, warrants, debt securities, shares of preferred stock, shares of common stock or any combination of such securities.

FORMS OF SECURITIES

Each debt security, warrant and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities will be issued in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Global Securities

Registered Global Securities.We may issue the registered debt securities, warrants and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

10

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants, guaranteed trust preferred securities or units, represented by a registered global security registered in the name of a depositary or its nominee, will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of Equinix, the trustees, the warrant agents, the unit agents or any other agent of Equinix, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

11

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and a successor depositary registered as a clearing agency under the Securities Exchange Act of 1934, as amended, is not appointed by us within 120 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

PLAN OF DISTRIBUTION

Equinix and/or the selling securityholders, if applicable, may sell the securities in one or more of the following ways (or in any combination) from time to time:

• to or through underwriters or dealers;

• in short or long transactions;

• directly to a limited number of purchasers or to a single purchaser;

• through agents; or

• through a combination of any of these methods of sale.

The prospectus supplement will state the terms of the offering of the securities, including:

• the name or names of any underwriters, dealers or agents;

• the purchase price of such securities and the proceeds to be received by Equinix, if any;

Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If Equinix and/or the selling securityholders, if applicable, use underwriters in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

• negotiated transactions;

• at a fixed public offering price or prices, which may be changed;

• “at the market offerings,” within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;

• at prices related to prevailing market prices; or

• at negotiated prices.

12

Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

Equinix and/or the selling securityholders, if applicable, may sell the securities through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best-efforts basis for the period of its appointment.

Equinix and/or the selling securityholders, if applicable, may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from Equinix at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Underwriters and agents may be entitled under agreements entered into with Equinix and/or the selling securityholders, if applicable, to indemnification by Equinix and/or the selling securityholders, if applicable, against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribution with respect to payments which the underwriters or agents may be required to make. Underwriters and agents may be customers of, engage in transactions with, or perform services for Equinix and its affiliates in the ordinary course of business.

Each series of securities other than the common stock, which is listed on The NASDAQ Global Select Market, and any series of debt securities outstanding on the date hereof, will be a new issue of securities and will have no established trading market. Any underwriters to whom securities are sold for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The securities, other than the common stock, may or may not be listed on a national securities exchange.
