Notice to Prospective Investors in the European Economic Area

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 (“EEA”). 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2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended or superseded, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II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 Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). 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 EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Regulation, and any offer of the notes in any Member State of the EEA is made pursuant to an exemption under the Prospectus Regulation.

MiFID II product governance/Professional investors and ECPs only target market

Solely for the purposes of each manufacturer’s product approval process, 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.

Notice to Prospective Investors in the United Kingdom

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 United Kingdom.

Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law in the United Kingdom by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the UK PRIIPs Regulation.

UK MiFIR product governance//Professional investors and ECPs only target market

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the notes has led to the conclusion that: (i) the target market for the notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook (“COBS”), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA (“UK MiFIR”); 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 the FCA Handbook Product Intervention and Product Governance Sourcebook (the “UK MiFIR Product Governance Rules”) 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.

FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein or therein, include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements include, among other things, statements regarding:

S-1

as well as all other statements other than statements of historical facts contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein or therein, including statements regarding our future operations, financial condition and prospects, and business strategies. Forward- looking statements generally can be identified by words such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” “plans,” “predicts,” “projects,” “will be,” “will continue,” “may,” “could,” “will likely result,” and similar expressions. These forward-looking statements are based on current expectations and assumptions that are subject to risks and uncertainties, which could cause our actual results to differ materially from those reflected in the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in this prospectus supplement and the accompanying prospectus, including in the sections captioned “Risk Factors,” in our 2024 Annual Report, and in particular, the risks discussed in the sections captioned “Note About Forward-Looking Statements” and “Item 1A. Risk Factors,” and those discussed in other documents we file with the SEC. Given these risks and uncertainties, you are cautioned not to place undue reliance on such forward-looking statements.

We undertake no obligation to revise or publicly release the results of any revision to these forward-looking statements, except as required by law. You are advised, however, to consult any additional disclosures we make in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and in our other filings we make with the SEC.

RISK FACTORS

An investment in the notes involves certain risks. You should carefully consider the risk factors described under “Risk Factors” in our 2024 Annual Report and as described in the Q1 2025 Quarterly Report, 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.

In addition to the foregoing risks relating to us, the following are additional risks relating to an investment in the notes.

The notes are unsecured and are effectively subordinated to our secured debt.

The notes are our unsecured general obligations. Holders of our secured indebtedness, if any, will have claims that are prior to your claims as holders of the notes, to the extent of the assets securing such indebtedness. Thus, in the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding, our pledged assets would be available to satisfy obligations of our secured indebtedness before any payment could be made on the notes. To the extent that such assets cannot satisfy in full our secured indebtedness, the holders of such indebtedness would have a claim for any shortfall that would rank equally in right of payment with the notes. 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 our secured indebtedness. As of March 31, 2025, Alphabet Inc. on a standalone basis had no secured indebtedness outstanding.

The notes are structurally subordinated to the existing and future liabilities of our subsidiaries.

We conduct most of our operations through our subsidiaries, which are separate and distinct legal entities from us. The notes are exclusively our obligations and are not guaranteed by our subsidiaries, which have no obligation to pay any amounts due on the notes or to provide us with funds to meet our payment obligations on the notes, whether in the form of dividends, distributions, loans or other payments. Our subsidiaries are not prohibited from incurring additional debt or other liabilities, including senior indebtedness, or from issuing equity interests that have priority over our interests in the subsidiaries. Consequently, the notes will be structurally subordinated to all existing and future liabilities of any of our subsidiaries and any subsidiaries that we may in the future acquire or establish. As of March 31, 2025, Google and certain other subsidiaries had approximately $2.1 billion in finance lease obligations and no long-term debt outstanding. Additionally, as of March 31, 2025, we have entered into leases primarily related to data centers that have not yet commenced with future lease payments of $17.3 billion, that are not yet recorded on our consolidated balance sheets, a portion of which will represent finance lease obligations. As of March 31, 2025, the notes would have been structurally subordinated to such existing third-party debt. If our subsidiaries were to incur additional debt or liabilities or to issue equity interests that have priority over our interests in our subsidiaries, our ability to pay our obligations on the notes could be adversely affected.

In addition, any payment of dividends, loans or advances by our subsidiaries could be subject to statutory or contractual restrictions. Payments to us by our subsidiaries will also be contingent upon the subsidiaries’ earnings and business considerations. Our right to receive any assets of any of our subsidiaries upon their bankruptcy, liquidation or reorganization, and therefore the right of the holders of the notes to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors. In addition, even if we are a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us.

S-8

The terms of the indenture and the notes provide only limited protection against significant corporate events and other actions we may take that could adversely impact your investment in the notes.

While the indenture and the notes contain terms intended to provide protection to the holders of the notes upon the occurrence of certain events involving significant corporate transactions, such terms are limited and may not be sufficient to protect your investment in the notes.

The indenture for the notes does not:

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 notes do not restrict our ability to engage in, or to otherwise be a party to, a variety of corporate transactions, circumstances and events that could have an adverse impact on your investment in the notes.

Our credit ratings may not reflect all risks of your investments in the notes.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the notes. These credit ratings may not reflect the potential impact of risks relating to the structure or marketing of the notes. Agency ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization. Each agency’s rating should be evaluated independently of any other agency’s rating.

There is no public market for the notes, which could limit their market price or your ability to sell them.

The notes are a new issue of securities for which there currently is no established trading market. Although we intend to apply for listing of the notes for trading on Nasdaq, no assurance can be given that the notes will become or will remain listed or that an active trading market for the notes will develop or, if developed, that it will continue. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time. The market price of the notes may be affected by a variety of factors, including a number of factors beyond our control and, in particular, all other factors being equal, an increase in prevailing interest rates will cause a decline in the market price of the notes. No assurance can be given:

If a market for the notes does not develop, investors may be unable to resell the notes for an extended period of time, if at all. If a market for the notes does develop, it may not continue or it may not be sufficiently liquid to allow holders to resell any of the notes. As a result, investors may not be able to liquidate their investment readily, and lenders may not readily accept the notes of such series as collateral for loans.

S-9

Redemption may adversely affect your return on the notes.

We have the right to redeem some or all of the notes prior to maturity. We may redeem any series of the notes at times when prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the amount received upon a redemption in a comparable security at an effective interest rate as high as that of the notes.

Holders of the notes will receive payments in euros.

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 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:

In addition, if one or more Member States of the European Monetary Union were to withdraw from the European Monetary Union and cease to use the euro as their currency, the value of the euro could be materially adversely affected.

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 the 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 volatility and the actions taken or to be taken by various national governments in response to the volatility 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

S-10

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 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, tax and legal advisors as to the risks involved in an investment in the notes.

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 described under “Description of the Notes—Issuance in Euro; Payment on the Notes.” 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. This exchange rate may be materially less favorable than the rate in effect at the time the notes were issued. 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.

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 euros 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 notes will be issued with a minimum denomination of €100,000 and multiples of €1,000 in excess thereof. It is possible that the clearing systems may process trades that could result in amounts being held in denominations smaller than the minimum denominations. If definitive notes are required to be issued in relation to such notes in accordance with the provisions of the relevant global notes, a holder who does not have the minimum denomination or any integral multiple of €1,000 in excess thereof in its account with the relevant clearing system at the relevant time may not receive all of its entitlement in the form of definitive notes unless and until such time as its holding satisfies the minimum denomination requirement.

S-11

The notes will initially be held in book-entry form and therefore investors must rely on the procedures of the relevant clearing systems to exercise any rights and remedies.

The notes will initially only be issued in registered global form and held through Clearstream and Euroclear. Interests in the global notes (as such term is defined in “Description of the Notes—Book-Entry; Delivery and Settlement—Global Clearance and Settlement”) will trade in book-entry form only. Unless and until the notes in definitive registered form are issued in exchange for book-entry interests, owners of book-entry interests will not be considered owners or holders of the notes. The common depositary (or its nominee) for the accounts of Clearstream and Euroclear will be the registered holder of the global notes. Payments in respect of the global notes representing the notes (including principal, premium, if any, interest and additional amounts, if any) will be made to the paying agent. The paying agent will then make such payments to the common depositary (or its nominee) for Clearstream and Euroclear. The common depositary (or its nominee) will in turn distribute such payments to participants in accordance with its procedures. After payment to the common depositary (or its nominee), we, the trustee and the paying agent will have no responsibility or liability for the payment of interest, principal or other amounts to the owners of book-entry interests. Accordingly, if you own a book-entry interest, you must rely on the procedures of Clearstream or Euroclear, as applicable, and if you are not a participant in Clearstream or Euroclear, on the procedures of the participant through which you own your interest, to exercise any rights and obligations of a holder of notes under the indenture. See “Description of the Notes—Book-Entry; Delivery and Settlement—Global Clearance and Settlement.” Payments in respect of the global notes representing the notes (including principal, premium, if any, interest and additional amounts, if any) will be made to the paying agent one business day prior to the date such payment is due.

Unlike the holders of the notes themselves, owners of book-entry interests will not have the direct right to act upon our solicitations for consents, requests for waivers or other actions from holders of the notes. Instead, if you own a book-entry interest, you will be permitted to act only to the extent you have received appropriate proxies to do so from Euroclear or Clearstream or, if applicable, a participant. There can be no assurance that procedures implemented for the granting of such proxies will be sufficient to enable you to vote on any request actions on a timely basis.

Similarly, upon the occurrence of an event of default under the indenture, unless and until notes in definitive registered form are issued in respect of all book-entry interests, if you own a book-entry interest, you will be restricted to acting through Clearstream or Euroclear. We, the trustee and the paying agent cannot assure you that the procedures to be implemented through Clearstream or Euroclear will be adequate to ensure the timely exercise of rights under the notes. See “Description of the Notes—Book-Entry; Delivery and Settlement—Global Clearance and Settlement.”

USE OF PROCEEDS

We estimate the net proceeds from the sale of the notes will be approximately €    in the aggregate, after deducting underwriting discounts and estimated offering expenses payable by us. We intend to use the net proceeds from these sales, together with the proceeds from the Concurrent USD Notes Offering, for general corporate purposes, which may include the repayment of outstanding debt.

Settlement of this offering is not conditioned upon settlement of the Concurrent USD Notes Offering or vice versa. The Concurrent USD Notes Offering is only being made pursuant to a separate prospectus supplement.

S-13

DESCRIPTION OF THE NOTES

The following description is a summary of the terms of the notes being offered. The descriptions in this prospectus supplement and the accompanying prospectus contain descriptions of certain terms of the notes and the indenture but do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the indenture that has been filed as an exhibit to the registration statement of which this prospectus supplement and the accompanying prospectus are a part, including the definitions of specified terms used in the indenture, and to the Trust Indenture Act of 1939, as amended. Wherever particular articles, sections or defined terms of the indenture are referred to, it is intended that those articles, sections or defined terms will be incorporated herein by reference, and the statement in connection with which reference is made is qualified in its entirety by the article, section or defined term in the indenture. This summary supplements the description of the debt securities in the accompanying prospectus, which applies to the notes being offered except to the extent the description in this prospectus supplement is inconsistent, in which case the following description replaces the corresponding description in the accompanying prospectus. For purposes of this description, references to the “Company,” “we,” “our” and “us” refer only to Alphabet Inc. and not to its subsidiaries.

General

The notes will constitute five series of securities under the indenture referred to below and will be issued only in fully registered form in minimum denominations of €100,000 and multiples of €1,000 in excess thereof. The notes will mature on the respective dates set forth below. The accompanying prospectus describes additional provisions of the notes and of the indenture, dated as of February 12, 2016, between us and The Bank of New York Mellon Trust Company, N.A., as trustee, under which we will issue the notes. There is no limit on the aggregate principal amount of notes that we may issue under the indenture. We reserve the right, from time to time and without the consent of any holders of the notes, to re-open any series of notes on terms identical in all respects to the outstanding notes of such series (except for the date of issuance, the date interest begins to accrue and, in certain circumstances, the first interest payment date), so that such additional notes will be consolidated with, form a single series with and increase the aggregate principal amount of the notes of such series; provided that the additional notes will have one or more separate CUSIP, ISIN or other identifying number unless they are issued pursuant to a “qualified reopening”, are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes. Such additional notes will have the same terms as to ranking, redemption, waivers, amendments or otherwise, as the applicable series of notes, and will vote together as one class on all matters with respect to such series of notes.

The 20 Notes will mature on     , 20 and will bear interest at a rate of    % per year. The 20 Notes will mature on     , 20 and will bear interest at a rate of    % per year. The 20 Notes will mature on    , 20 and will bear interest at a rate of    % per year. The 20 Notes will mature on    , 20 and will bear interest at a rate of    % per year. The 20 Notes will mature on     , 20 and will bear interest at a rate of    % per year. We will pay interest on the notes annually in arrears on     of each year, beginning on    , 2026, to the record holders at the close of business on the Clearing System Business Day prior to the applicable interest payment date, where “Clearing System Business Day” means every Monday to Friday, inclusive, except December 25th and January 1st, subject to certain exceptions.

Interest payable on the notes on any interest payment date, redemption date or maturity date shall be the amount of interest accrued from, and including, the next preceding interest payment date in respect of which interest has been paid or duly provided for (or from and including the original issue date of the notes, if no interest has been paid or duly provided for) to, but not including, such interest payment date, redemption date or maturity date, as the case may be. Interest on the notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the notes (or     , 2025 if no interest has been paid on the notes), to, but not including, the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association.

S-14

If any interest payment date, maturity date or any redemption date of the notes falls on a day that is not a business day, the related payment of principal, premium, if any, or interest will be made on the next succeeding business day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding business day.

The term “business day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates. The rights of holders of beneficial interests of notes to receive the payments of interest on such notes are subject to the applicable procedures of Clearstream and Euroclear.

Issuance in Euro; Payment on the Notes

Initial holders will be required to pay for the notes in euros, and all payments on the notes will be payable in euros; provided that 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 euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. dollar/euro exchange rate published in The Wall Street Journal on or prior to the second business day prior to the relevant payment date. 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. Neither the trustee nor the paying agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Investors will be subject to foreign exchange risks as to payments on the notes that may have important economic and tax consequences to them. See “Risk Factors” and the discussion of the foreign currency rules under “Material United States Federal Income Tax Considerations.”

Ranking

The notes will be our senior unsecured indebtedness and will rank equally with each other and with all of our other senior unsecured and unsubordinated indebtedness from time to time outstanding. However, the notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries (including Google) and will be effectively subordinated to any secured indebtedness to the extent of the value of the assets securing such indebtedness. Claims of the creditors of our subsidiaries will generally have priority with respect to the assets and earnings of such subsidiaries over the claims of our creditors, including holders of the notes. Accordingly, the notes will be effectively subordinated to the claims of third-party creditors, including trade creditors and preferred stockholders, if any, of our subsidiaries.

Listing

We intend to apply to list each series of the notes on Nasdaq. The listing applications will be subject to approval by Nasdaq. We currently expect trading in each series of the notes on Nasdaq to begin within 30 days after the original issue date. If such a listing is obtained, we have no obligation to maintain such listing and we may delist any series of the notes at any time. Currently, there is no public market for any series of the notes.

Optional Redemption

We may redeem any series of the notes in whole or in part at any time or from time to time at the applicable redemption prices. If we redeem the 20 Notes prior to    , 20 (the date that is    months prior to

S-15

the maturity date of the 20 Notes) (the “20 Par Call Date”), the 20 Notes prior to    , 20 (the date that is    months prior to the maturity date of the 20 Notes) (the “20 Par Call Date”), the 20 Notes prior to    , 20 (the date that is    months prior to the maturity date of the 20 Notes) (the “20 Par Call Date”), the 20 Notes prior to     , 20 (the date that is     months prior to the maturity date of the 20 Notes) (the “20 Par Call Date”), and the 20 Notes prior to     , 20 (the date that is     months prior to the maturity date of the 20 Notes) (the “20 Par Call Date” and, each of the 20 Par Call Date, the 20 Par Call Date, the 20 Par Call Date, the 20 Par Call Date and the 20 Par Call Date, a “Par Call Date”), we will pay a redemption price equal to the greater of (i) 100% of the principal amount of the notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed (exclusive of interest accrued to the redemption date), discounted to the redemption date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus    basis points with respect to the 20 Notes, plus    basis points with respect to the 20 Notes, plus    basis points with respect to the 20 Notes, plus    basis points with respect to the 20 Notes and plus    basis points with respect to the 20    Notes, plus, in either case, accrued and unpaid interest, if any, to, but not including, the redemption date.

On or after the 20 Par Call Date, with respect to the 20 Notes, the 20 Par Call Date, with respect to the 20 Notes, the 20 Par Call Date, with respect to the 20 Notes, the 20 Par Call Date, with respect to the 20 Notes and the 20 Par Call Date, with respect to the 20 Notes, we may redeem such notes of the applicable series in whole or in part at any time or from time to time at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest, if any, to, but not including, the redemption date.

“Comparable Government Bond Rate” means, with respect to any redemption date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third business day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such redemption date.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such notes.

“Independent Investment Banker” means one of the Reference Government Bond Dealers selected by us.

“Comparable Government Bond Price” means, with respect to any redemption date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if we obtain fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations.

“Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any redemption date, the arithmetic average, as determined by us, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third business day preceding such redemption date.

“Reference Government Bond Dealer” means (i) each of Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, Barclays Bank PLC, Deutsche Bank AG, London Branch, or any of their affiliates that are

S-16

primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), we shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by us.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The trustee shall not be responsible for determining or calculating the redemption price or selecting any Independent Investment Banker.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with Clearstream or Euroclear procedures, as applicable) at least 10 but not more than 60 days before the redemption date to each holder of record of the notes to be redeemed at its registered address. The notice of redemption for such notes will state, among other things, the amount of notes to be redeemed, the redemption date, the manner in which the redemption price will be calculated and the place or places that payment will be made upon presentation and surrender of notes to be redeemed. Unless we default in the payment of the redemption price, interest will cease to accrue on any notes that have been called for redemption at the redemption date.

The notes are also subject to redemption prior to maturity if certain changes in U.S. tax law occur. If such changes occur, the notes may be redeemed at a redemption price of 100% of their principal amount plus accrued and unpaid interest, if any, to, but not including, the redemption date. See “—Redemption for Tax Reasons.”

No notes of a principal amount of €1,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by Clearstream or Euroclear, as applicable, the redemption and the selection of notes to be redeemed shall be in accordance with the policies and procedures of the applicable clearing system.

Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or portions thereof called for redemption.

The notes are not entitled to the benefit of a sinking fund.

Notice of any redemption of the notes in connection with a transaction or an event may, at our discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at our discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At our discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. We will provide written notice to the trustee prior to the close of business two business days prior to the redemption date if any such redemption has been rescinded or delayed, and upon receipt the trustee will provide such notice to each holder of the notes to be redeemed in the same manner in which the notice of redemption was given.

Payment of Additional Amounts

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the notes such additional amounts as are necessary in order that the net payment by us or a paying agent of the principal, premium, if any, and interest with respect to the notes to the beneficial owner that is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in the notes to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

S-17

S-18

Except as specifically provided under this heading “—Payment of Additional Amounts,” we will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this prospectus supplement and the accompanying prospectus to any payment on the notes include the related payment of additional amounts, as applicable.

As used under this heading “—Payment of Additional Amounts” and under the heading “—Redemption for Tax Reasons,” the term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) 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 (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

Redemption for Tax Reasons

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after the date of this prospectus supplement, we become or, based upon a written opinion of independent counsel selected by us, will become obligated to pay additional amounts as described herein under the heading “—Payment of Additional Amounts” with respect to the notes of any series, then we may at any time at our option redeem, in whole, but not in part, the notes of such series on not less than 10 nor more than 60 days’ prior notice, at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, on the notes of such series to be redeemed to, but not including, the redemption date.

Satisfaction and Discharge

We may discharge certain obligations to holders of the notes of any series that have not already been delivered to the trustee for cancellation and that either have become due and payable or will become due and payable within one year (or are to be called for redemption within one year) by depositing with the trustee, in trust, money or foreign government securities or a combination thereof in an amount sufficient to pay and discharge the entire indebtedness including the principal and premium, if any, and interest to the date of such deposit (if the notes have become due and payable) or to the maturity thereof or the redemption date of the notes of such series, as the case may be.

Book-Entry; Delivery and Settlement

We have obtained the information in this section concerning Clearstream Banking, S.A. (“Clearstream”) and Euroclear Bank SA/NV (“Euroclear”) and their book-entry systems and procedures from sources we believe to be reliable. The description of the clearing systems in this section reflects our understanding of the rules and procedures of Clearstream and Euroclear as they are currently in effect. Those systems could change their rules and procedures at any time.

S-19

Global Clearance and Settlement

The notes will be issued in the form of one or more fully registered global notes (the “global notes”) and will be deposited with a common depositary for, and in respect of interests held through, Clearstream and Euroclear. Except as described herein, certificates will not be issued in exchange for beneficial interests in the global notes.

Except as set forth below, the global notes may be transferred, in whole and not in part, only to Clearstream or Euroclear or their respective nominees.

Beneficial interests in the global notes will be represented, and transfers of such beneficial interests will be effected, through accounts of financial institutions acting on behalf of beneficial owners as direct or indirect participants in Clearstream or Euroclear. Those beneficial interests will be held in denominations of €100,000 and additional multiples of €1,000 in excess thereof. Investors may hold notes directly through Clearstream or Euroclear, if they are participants in such systems, or indirectly through organizations that are participants in such systems.

Owners of beneficial interests in the global notes will not be entitled to have notes registered in their names, and will not receive or be entitled to receive physical delivery of notes in definitive form. Except as provided below, beneficial owners will not be considered the owners or holders of the notes under the indenture, including for purposes of receiving any reports delivered by us or the trustee pursuant to the indenture. Accordingly, each beneficial owner must rely on the procedures of the clearing systems and, if such person is not a participant of the clearing systems, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indenture. Under existing industry practices, if we request any action of holders or a beneficial owner desires to give or take any action a holder is entitled to give or take under the indenture, the clearing systems would authorize their participants holding the relevant beneficial interests to give or take action and the participants would authorize beneficial owners owning through the participants to give or take such action or would otherwise act upon the instructions of beneficial owners. Conveyance of notices and other communications by the clearing systems to their participants, by the participants to indirect participants and by the participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. These limits and laws may impair the ability to transfer beneficial interests in global notes.

Persons that are not Clearstream or Euroclear participants may beneficially own notes held by the common depositary for Clearstream and Euroclear only through direct or indirect participants in Clearstream and Euroclear. So long as the common depositary for Clearstream and Euroclear is the registered owner of the global note, the common depositary for all purposes will be considered the sole holder of the notes represented by the global note under the indenture and the global note.

The policies of Clearstream and Euroclear will govern payments, transfers, exchanges and other matters relating to an investor’s interest in the notes held by them. We have no responsibility for any aspect of the records kept by Clearstream or Euroclear or any of their direct or indirect participants. We also do not supervise these systems in any way.

Euroclear

Euroclear advises that it was created in 1968 to hold securities for its participants (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing, and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.A. (the “Euroclear Operator”), under contract with Euroclear Clearance Systems, S.C., a Belgian cooperative corporation (the “Cooperative”).

S-20

All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding through Euroclear Participants.

Distributions with respect to the notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by its depositary.

Euroclear further advises that investors that acquire, hold and transfer interests in the notes by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global notes.

The Euroclear Operator advises as follows: under Belgian law, investors that are credited with securities on the records of the Euroclear Operator have a co-property right in the fungible pool of interests in securities on deposit with the Euroclear Operator in an amount equal to the amount of interests in securities credited to their accounts. In the event of the insolvency of the Euroclear Operator, Euroclear Participants would have a right under Belgian law to the return of the amount and type of interests in securities credited to their accounts with the Euroclear Operator. If the Euroclear Operator did not have a sufficient amount of interests in securities on deposit of a particular type to cover the claims of all Participants credited with such interests in securities on the Euroclear Operator’s records, all Participants having an amount of interests in securities of such type credited to their accounts with the Euroclear Operator would have the right under Belgian law to the return of their pro rata share of the amount of interests in securities actually on deposit.

Under Belgian law, the Euroclear Operator is required to pass on the benefits of ownership in any interests in securities on deposit with it (such as dividends, voting rights and other entitlements) to any person credited with such interests in securities on its records.

Clearstream

Clearstream advises that it is incorporated under the laws of Luxembourg and licensed as a bank and professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Customers”) and facilitates the clearance and settlement of securities transactions between Clearstream Customers through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in over 30 countries through established depository and custodial relationships. Clearstream has established an electronic bridge with the Euroclear Operator to facilitate the settlement of trades between Euroclear and Clearstream. As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission

S-21

de Surveillance du Secteur Financier). Clearstream Customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Clearstream’s U.S. customers are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to other institutions, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Customer, either directly or indirectly.

Distributions with respect to the notes held through Clearstream will be credited to cash accounts of Clearstream Customers in accordance with its rules and procedures.

Clearstream and Euroclear Arrangements

So long as Clearstream or Euroclear or their nominee or their common depositary is the registered holder of the global notes, Clearstream, Euroclear or such nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such global notes for all purposes under the indenture and the notes. Payments of principal, premium, if any, and interest in respect of the global notes will be made to Clearstream, Euroclear or such nominee, as the case may be, as registered holder thereof. None of us, the trustee, transfer agent, paying agent and registrar, any underwriter and any affiliate of any of the above or any person by whom any of the above is controlled (as such term is defined in the Securities Act of 1933, as amended) will have any responsibility or liability for any records relating to or payments made on account of beneficial ownership interests in the global notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Distributions of principal, premium, if any, and interest with respect to the global notes will be credited in euro to the extent received by Clearstream or Euroclear from the paying agent to the cash accounts of Clearstream or Euroclear customers in accordance with the relevant system’s rules and procedures.

Because Clearstream and Euroclear can only act on behalf of participants, who in turn act on behalf of indirect participants, the ability of a person having an interest in the global notes to pledge such interest to persons or entities that do not participate in the relevant clearing system, or otherwise take actions in respect of such interest, may be affected by the lack of a physical certificate in respect of such interest.

Initial Settlement

We understand that investors that hold their notes through Clearstream or Euroclear accounts will follow the settlement procedures that are applicable to conventional eurobonds in registered form. Subject to applicable procedures of Clearstream and Euroclear, notes will be credited to the securities custody accounts of Clearstream and Euroclear participants on the business day following the settlement date, for value on the settlement date.

Secondary Market Trading

Because the purchaser determines the place of delivery, it is important to establish at the time of trading of any notes where both the purchaser’s and seller’s accounts are located to ensure that settlement can be made on the desired value date.

We understand that secondary market trading between Clearstream and/or Euroclear participants will occur in the ordinary way following the applicable rules and operating procedures of Clearstream and Euroclear. Secondary market trading will be settled using procedures applicable to conventional eurobonds in registered form.

You should be aware that investors will only be able to make and receive deliveries, payments and other communications involving the notes through Clearstream and Euroclear on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

S-22

In addition, because of time-zone differences, there may be problems with completing transactions involving Clearstream and Euroclear on the same business day as in the United States. U.S. investors who wish to transfer their interests in the notes, or to make or receive a payment or delivery of the notes, on a particular day, may find that the transactions will not be performed until the next business day in Brussels or Luxembourg, depending on whether Clearstream or Euroclear is used.

Clearstream and Euroclear will credit payments to the cash accounts of Clearstream Customers or Euroclear Participants, as applicable, in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. Clearstream or the Euroclear Operator, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Clearstream Customer or Euroclear Participant only in accordance with its relevant rules and procedures.

Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the notes among participants of Clearstream and Euroclear. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

Certificated Notes

If the applicable depositary is at any time unwilling or unable to continue as depositary for any of the global notes and a successor depositary is not appointed by us within 90 days, we will issue the notes in definitive form in exchange for the applicable global notes. We will also issue the notes in definitive form in exchange for the global notes if an event of default has occurred with regard to the notes represented by the global notes and has not been cured or waived. In addition, we may at any time and in our sole discretion determine not to have the notes represented by the global notes and, in that event, will issue the notes in definitive form in exchange for the global notes. In any such instance, an owner of a beneficial interest in the global notes will be entitled to physical delivery in definitive form of the notes represented by the global notes equal in principal amount to such beneficial interest and to have such notes registered in its name. The notes so issued in definitive form will be issued as registered in minimum denominations of €100,000 and integral multiples of €1,000 thereafter, unless otherwise specified by us. The notes in definitive form can be transferred by presentation for registration to the registrar at our office or agency for such purpose and must be duly endorsed by the holder or his or her attorney duly authorized in writing, or accompanied by a written instrument or instruments of transfer in form satisfactory to us or the registrar duly executed by the holder or his attorney duly authorized in writing. We may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any exchange or registration of transfer of definitive notes.

Concerning the Trustee, Paying Agent, Transfer Agent and Registrar

The Bank of New York Mellon Trust Company, N.A. will be the trustee, transfer agent and registrar with respect to the notes. The Bank of New York Mellon, London Branch, will initially act as paying agent with respect to the notes.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material U.S. federal income tax considerations that may be relevant to a holder of a note. This summary is based on provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury regulations, laws, rulings and decisions now in effect, all of which are subject to change, possibly with retroactive effect. This summary deals only with beneficial owners of notes that will hold notes as capital assets for U.S. federal income tax purposes and acquired notes upon original issuance at their issue price. This summary does not address particular tax considerations that may be applicable to investors that are subject to special tax rules, such as banks, tax-exempt entities, insurance companies, regulated investment companies, dealers in securities or currencies, traders in securities electing to mark to market their securities for U.S. federal income tax purposes, persons that will hold notes as a position in a “straddle” or conversion transaction, or as part of a “synthetic security” or other integrated financial transaction, entities taxed as partnerships or the partners therein, U.S. expatriates, nonresident alien individuals present in the United States for more than 182 days in a taxable year, or U.S. holders (as defined below) that have a “functional currency” other than the U.S. dollar.

This summary addresses only U.S. federal income tax consequences, and does not address consequences arising under state, local or non-U.S. tax laws, the alternative minimum tax or the Medicare tax on net investment income or under special timing rules prescribed under section 451(b) of the Code. Investors should consult their own tax advisors in determining the tax consequences to them of holding notes under such tax laws, as well as the application to their particular situation of the U.S. federal income tax considerations discussed below.

As used herein, a “U.S. holder” is a beneficial owner of a note that is, for U.S. federal income tax purposes, a citizen or resident of the United States or a domestic corporation or that otherwise is subject to U.S. federal income taxation on a net income basis in respect of the note. A “non-U.S. holder” is a beneficial owner of a note that is an individual, corporation, estate, or trust that is, in each case, not a U.S. holder.

U.S. Holders

Payments of Interest

Payments of stated interest will be taxable to a U.S. holder as ordinary interest income at the time that such payments are accrued or are actually or constructively received (in accordance with the U.S. holder’s method of tax accounting for U.S. federal income tax purposes). It is expected, and this discussion assumes, that the notes will not be issued with original issue discount (“OID”) in an amount equal to or in excess of a de minimis amount for U.S. federal income tax purposes. In general, however, if the notes are issued with OID that is equal to or more than a de minimis amount, regardless of a U.S. holder’s regular method of accounting for U.S. federal income tax purposes, the U.S. holder will be required to include OID as ordinary gross income under a “constant yield method” before the receipt of cash attributable to such income. OID generally will be accrued in euros and translated into dollars at the average exchange rate in effect during the interest accrual period (or portion thereof within the holder’s taxable year). The U.S. holder generally will recognize foreign currency gain or loss to the extent the amount accrued differs from the U.S. dollar value of the euros amounts when received.

A U.S. holder that uses the cash method of accounting for U.S. federal income tax purposes and that receives a payment of interest on a note will be required to include in ordinary income the U.S. dollar value of the euros interest payment determined based on the exchange rate in effect on the date the payment is received, regardless of whether the payment is in fact converted to U.S. dollars. A U.S. holder that uses the accrual method of accounting for U.S. federal income tax purposes will accrue interest income on a note in euros and translate the amount accrued into U.S. dollars based on the average exchange rate in effect during the interest accrual period (or portion thereof within the holder’s taxable year), or at the holder’s election, at the spot rate of exchange on the last day of the accrual period (or the last day of the taxable year within such accrual period if the accrual period spans more than one taxable year), or at the spot rate of exchange on the date of receipt, if that date is

S-24

within five business days of the last day of the accrual period. 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 Internal Revenue Service (the “IRS”).

A U.S. holder who uses the accrual method will recognize foreign currency gain or loss, as the case may be, on the receipt of an interest payment made with respect to a note (including amounts received upon the sale of a note attributable to accrued interest previously included in income as described below under “—Sale, Exchange, Redemption or Retirement of Notes”) if the exchange rate in effect on the date the payment is received differs from the rate applicable to a previous accrual of that interest income. This foreign currency gain or loss will generally be treated as ordinary income or loss and will not be treated as an adjustment to interest income received on the note.

Sale, Exchange, Redemption or Retirement of Notes

Upon the sale, exchange, redemption or retirement of a note, a U.S. holder generally will recognize gain or loss equal to the difference between the amount realized on the sale, exchange, redemption or retirement (less any accrued but unpaid interest, which will be taxable as ordinary interest income as described above) and the U.S. holder’s tax basis in such note.

A U.S. holder’s tax basis in a note generally will be the U.S. dollar value of the purchase price of that note on the date of purchase. The amount realized upon the sale, exchange, redemption or retirement of a note will be the U.S. dollar value of the currency received calculated at the exchange rate in effect on the date the instrument is sold, exchanged, redeemed or retired. If the notes are treated as traded on an established securities market, a U.S. holder who uses the cash method, and if it so elects, a U.S. holder who uses the accrual method, will determine the U.S. dollar value of the amount realized by translating such amount at the spot rate on the settlement date of the sale. The election available to U.S. holders who use the accrual method in respect of the purchase and sale of notes traded on an established securities market must be applied consistently to all debt instruments from year to year and cannot be changed without the consent of the IRS. U.S. holders should consult their own tax advisors about the availability of this treatment (and in the case of accrual basis U.S. holders, the advisability of making this election).

Subject to the foreign currency rules discussed below, gain or loss recognized by a U.S. holder generally will be long-term capital gain or loss if the U.S. holder has held the note for more than one year at the time of disposition. Long-term capital gains recognized by an individual holder generally are subject to tax at a lower rate than short-term capital gains or ordinary income. The deductibility of capital losses is subject to limitations.

Gain or loss recognized by a U.S. holder on the sale, exchange, redemption or retirement of a note generally will be treated as ordinary income or loss to the extent that the gain or loss is attributable to changes in exchange rates during the period in which the U.S. holder held the note. This foreign currency gain or loss will not be treated as an adjustment to interest income received on the note. In addition, upon the sale, exchange, redemption or retirement of a note, a U.S. holder that uses the accrual method may realize foreign currency gain or loss attributable to amounts received in respect of accrued and unpaid interest. The amount of foreign currency gain or loss realized with respect to principal and accrued interest will, however, be limited to the amount of overall gain or loss realized on the disposition. For a U.S. holder that uses the accrual method and does not make the election described above, the foreign currency gain or loss may include amounts attributable to changes in exchange rates between the trade date and the settlement date.

Reportable Transactions

A U.S. holder that participates in a “reportable transaction” will be required to disclose its participation to the IRS. The scope and application of these rules is not entirely clear. A U.S. holder may be required to treat a foreign currency exchange loss relating to a note as a reportable transaction if the loss equals or exceeds $50,000

S-25

in a single taxable year if the U.S. holder is an individual or trust, or higher amounts for other U.S. holders. In the event the acquisition, ownership or disposition of a note constitutes participation in a “reportable transaction” for purposes of these rules, a U.S. holder will be required to disclose its investment to the IRS, currently on Form 8886. Prospective purchasers should consult their tax advisors regarding the application of these rules.

Non-U.S. Holders

Payments of Interest

Subject to the discussions below under “—Information Reporting and Backup Withholding” and “—FATCA,” payments of interest on the notes to a non-U.S. holder generally will be exempt from U.S. federal income tax under the portfolio interest exemption provided that (i) the non-U.S. holder properly certifies that it is not a U.S. person by providing a properly executed IRS Form W-8BEN or W-8BEN-E or other applicable IRS Form W-8, to the applicable withholding agent; (ii) the non-U.S. holder does not actually or constructively own 10% or more of the total combined voting power of our stock entitled to vote; and (iii) the non-U.S. holder is not a controlled foreign corporation that is related to us actually or constructively through stock ownership.

Sale, Exchange, Redemption or Retirement of Notes

Subject to the discussions below under “—Information Reporting and Backup Withholding” and “—FATCA,” a non-U.S. holder generally will not be subject to U.S. federal income tax on gain recognized on a sale, exchange, redemption, retirement or other disposition of notes (however, to the extent any portion of the amount realized by a non-U.S. holder on a sale, exchange, redemption, retirement or other disposition of notes is attributable to accrued but unpaid interest, such portion shall be treated as described above in “—Non-U.S. Holders—Payments of Interest”).

Information Reporting and Backup Withholding

Information returns will be filed with the IRS in connection with payments on the notes made to, and the proceeds of dispositions of notes effected by, certain U.S. holders. In addition, certain U.S. holders may be subject to backup withholding (currently at a rate of 24%) in respect of such amounts if they do not provide their taxpayer identification numbers to the person from whom they receive payments or otherwise comply with applicable requirements. A holder that is not a “United States person” (as defined in the Code) may be required to comply with applicable certification procedures to establish that they are exempt from such information reporting requirements and backup withholding. The amount of any backup withholding from a payment to a U.S. or non-U.S. holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.

FATCA

Under the U.S. tax rules known as the Foreign Account Tax Compliance Act (“FATCA”), a holder of notes will generally be subject to 30% U.S. withholding tax on interest payments on the notes if the holder is not FATCA compliant or holds its notes through a foreign financial institution that is not FATCA compliant, unless an exemption applies. In order to be treated as FATCA compliant, a holder must provide us or an applicable withholding agent certain documentation (usually an IRS Form W-9, W-8BEN or W-8BEN-E) containing information about its identity, its FATCA status, and if required, its direct and indirect U.S. owners. These requirements may be modified by the adoption or implementation of an intergovernmental agreement between the United States and another country or by future U.S. Treasury regulations. If any taxes are required to be deducted or withheld from any payments in respect of the notes as a result of a beneficial owner or intermediary’s failure to comply with the foregoing rules, no additional amounts will be paid on the notes as a result of the deduction or withholding of such tax.

S-26

Documentation that holders provide in order to be treated as FATCA compliant may be reported to the IRS and other tax authorities, including information about a holder’s identity, its FATCA status, and if applicable, its direct and indirect U.S. owners. Prospective investors should consult their own tax advisers about how information reporting and the possible imposition of withholding tax under FATCA may apply to their investment in the notes.

CERTAIN EUROPEAN UNION TAX CONSIDERATIONS

The Proposed Financial Transaction Tax

The Proposed Financial Transaction Tax

On 14 February 2013, the European Commission published a proposal for a directive for a common financial transaction tax (the “FTT”) in Austria, Belgium, Estonia, France, Germany, Greece, Italy, Portugal, Slovakia, Slovenia and Spain (the “Participating Member States”). Political consensus on a final directive for the FTT has not yet been achieved as of the date hereof. Additional EU Member States may decide to participate and/or certain of the Participating Member States (in addition to Estonia which meanwhile withdrew) may decide to withdraw.

Whether the FTT will ultimately be implemented and, if so, in what form, as well as the transactions that may be covered by it, is uncertain at this stage. If enacted, the FTT could apply under certain circumstances to transactions involving the notes. The mechanism by which the FTT would be applied and collected is not yet known, but if the FTT or any similar tax is adopted, transactions in the notes could be subject to higher costs, and the liquidity of the market for the notes may be diminished.

Prospective holders of the notes are advised to seek their own professional advice in relation to the consequences of the FTT that could be associated with subscribing for, purchasing, holding and disposing of the notes.

UNDERWRITING

Subject to the terms and conditions contained in a terms agreement, dated as of the date of this prospectus supplement between us and the underwriters named below, for whom Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, Barclays Bank PLC and Deutsche Bank AG, London Branch are acting as representatives, which incorporates by reference the underwriting agreement, dated as of the date of this prospectus supplement, we have agreed to sell to each underwriter, and each underwriter has severally agreed to purchase from us, the principal amount of notes set forth opposite its name below:

The underwriters are offering the notes subject to their acceptance of the notes from us, and subject to prior sale. The terms agreement provides that the obligations of the several underwriters to pay for and accept delivery of the notes offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the notes offered by this prospectus supplement if any such notes are taken. The underwriters will sell the notes to the public when and if the underwriters buy the notes from us. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The underwriters initially propose to offer part of the notes of each series directly to the public at the offering prices described on the cover page of this prospectus supplement. In addition, the underwriters initially propose to offer part of the notes to certain dealers at a price that represents a concession not in excess of    % of the principal amount of the 20 Notes,    % of the principal amount of the 20 Notes,    % of the principal amount of the 20 Notes,    % of the principal amount of the 20 Notes and % of the principal amount of the 20 Notes. Any underwriter may allow, and any such dealer may reallow, a concession not in excess of % of the principal amount of the 20 Notes, % of the principal amount of the 20 Notes,    % of the principal amount of the 20 Notes,    % of the principal amount of the 20 Notes and % of the principal amount of the 20 Notes to certain other dealers. After the initial offering of the notes, the underwriters may from time to time vary the offering price and other selling terms. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The following table shows the underwriting discounts that we will pay to the underwriters in connection with this offering:

S-29

Expenses associated with this offering to be paid by us, other than underwriting discounts, are estimated to be €    .

We have also agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.

Extended Settlement

We expect to deliver the notes against payment for the notes on the fourth London business day following the date of the pricing of the notes (this settlement cycle is referred to as “T+4”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market are generally required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on any day prior to the business date before delivery will be required, by virtue of the fact that the notes initially settle in T+4, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement and should consult their own advisors.

New Issue of Notes

The notes are a new issue of securities, and there is currently no established trading market for the notes. We intend to apply to list each series of the notes on Nasdaq. The listing applications will be subject to approval by Nasdaq. We currently expect trading in each series of the notes on Nasdaq to begin within 30 days after the original issue date. If such a listing is obtained, we have no obligation to maintain such listing and we may delist any series of the notes at any time. Currently, there is no public market for any series of the notes. The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so. The underwriters may discontinue any market making in the notes at any time at 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 you receive when you sell will be favorable.

Price Stabilization

In connection with the offering of the notes, Goldman Sachs & Co. LLC (in this capacity, the “Stabilizing Manager”) (or persons acting on behalf of the Stabilizing Manager) may engage in transactions that stabilize, maintain or otherwise affect the prices of the notes. Specifically, the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) may overallot in connection with the offering of the notes, creating a syndicate short position. In addition, the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) may bid for, and purchase, notes in the open market to cover syndicate short positions or to stabilize the prices of the notes. Finally, the underwriting syndicate may reclaim selling concessions allowed for distributing the notes in the offering of the notes, if the syndicate repurchases previously distributed notes in syndicate covering transactions, stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market prices of the notes above independent market levels. The Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) is not required to engage in any of these activities, and may be discontinued at any time and without notice. We cannot assure you that the Stabilizing Manager (or persons

S-30

acting on behalf of the Stabilizing Manager) will undertake any stabilization action. To the extent required under applicable law, any stabilization action may only 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 will be conducted by the Stabilizing Manager (or any person acting on behalf of the Stabilizing Manager) in accordance with 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, financing and brokerage activities. From time to time in the ordinary course of their respective businesses, certain of the underwriters and their affiliates have engaged in and may in the future engage in commercial banking, financial advisory, derivatives and/or investment banking transactions with us and our affiliates. Affiliates of some of the underwriters are agents under our commercial paper program for which these affiliates have been and will be paid customary fees. 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) 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 issuer. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, certain other of those underwriters or their affiliates have hedged and may in the future hedge or otherwise reduce their exposure, and certain other of those underwriters may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge or otherwise reduce 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. The underwriters and their respective 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.

Sales Outside the United States

European Economic Area

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 (the “EEA”). 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, the “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution 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 Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended or superseded, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared, and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the notes in any member state of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of securities. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Regulation.

S-31

United Kingdom

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 United Kingdom (the “UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (the “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of assimilated law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes based investment products or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

This prospectus supplement and the accompanying prospectus has been prepared on the basis that any offer of notes in the UK will be made pursuant to an exemption under the UK Prospectus Regulation and FSMA from the requirement to publish a prospectus for offers of notes. This ‘prospectus supplement’ and there are references herein to a “prospectus,” neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the UK Prospectus Regulation or the FSMA.

This prospectus supplement and the accompanying prospectus have not been approved by an authorized person for the purposes of section 21 of the FSMA and accordingly, are only being distributed to, and must not be passed on to, the general public in the UK.

ALPHABET INC.

Alphabet is a collection of businesses — the largest of which is Google. We report Google in two segments, Google Services and Google Cloud, and all non-Google businesses collectively as Other Bets. Supporting these businesses, we have centralized certain AI-related research and development which is reported in Alphabet-level activities. Alphabet’s structure is about helping each of our businesses prosper through strong leaders and independence.

At Google, our product innovations are what make our services widely used, and our brand one of the most recognized in the world. Google Services’ core products and platforms include ads, Android, Chrome, devices, Gmail, Google Drive, Google Maps, Google Photos, Google Play, Search, and YouTube, with broad and growing adoption by users around the world. We have built world-class advertising technologies for advertisers, agencies and publishers to power their digital marketing businesses. Google Services generates revenues primarily by delivering both performance and brand advertising that appears on Google Search & other properties, YouTube, and Google Network partners’ properties. In addition, Google Services increasingly generates revenues from products and services beyond advertising including:

Google Cloud generates revenues through our Google Cloud Platform and Google Workspace offerings primarily from consumption-based fees and subscriptions for infrastructure, platform, applications, and other cloud services. Customers use Google Cloud in multiple ways such as: AI-optimized infrastructure; developer platforms through the Vertex AI platform; cybersecurity; data and analytics; applications, including Gemini for Google Cloud and Gemini for Google Workspace.

Across Alphabet, we are using technology to try and solve big problems that affect a wide variety of industries, including transportation and health technology. Alphabet’s investment in the portfolio of Other Bets includes businesses that are at various stages of development, ranging from those in the R&D phase to those that are in the beginning stages of commercialization. Our goal is for them to become thriving, successful businesses. Revenues from Other Bets are generated primarily from the sale of healthcare-related services, and internet services.

Google was incorporated in California in September 1998 and re-incorporated in the State of Delaware in August 2003. In 2015, we implemented a holding company reorganization, and as a result, Alphabet became the successor registrant to our wholly-owned subsidiary, Google. Our headquarters are located at 1600 Amphitheatre Parkway, Mountain View, California 94043, and our telephone number is (650) 253-0000. Our Class C Capital Stock and Class A Common Stock are listed on The NASDAQ Global Select Market under the symbols “GOOG” and “GOOGL” respectively. We maintain a number of websites, including www.abc.xyz. The information on, or accessible through, our websites is not part of this prospectus.

USE OF PROCEEDS

Unless the applicable prospectus supplement indicates otherwise, we intend to use net proceeds from the sale of the securities offered hereby for general corporate purposes, including to refinance or to repay outstanding indebtedness if so specified in the applicable prospectus supplement. We may temporarily invest funds that are not immediately needed for these purposes in short-term marketable securities.

Unless the applicable prospectus supplement indicates otherwise, we will not receive any proceeds from the sale of securities by selling security holders.

DESCRIPTION OF DEBT SECURITIES

We may offer secured or unsecured debt securities, which may be convertible or non-convertible, in one or more series.

The following is a summary of certain general terms and provisions of the debt securities and the indenture, but they are not complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of an indenture, dated as of February 12, 2016, entered into between us and The Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented from time to time (the “indenture”), which has been filed as an exhibit to the registration statement of which this prospectus is a part, including the definitions of specified terms used in the indenture, and to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The particular terms of the debt securities offered by any prospectus supplement and the extent these general provisions may apply to the debt securities will be described in the applicable prospectus supplement. If a different trustee or a different indenture for a series of debt securities is used, those details will be provided in a prospectus supplement and the forms of any other indentures will be filed with the SEC at the time they are used. The terms of the debt securities will include those set forth in the applicable indenture, any related documents and those made a part of the indenture by the Trust Indenture Act. You should read the summary below, the applicable prospectus supplement and the provisions of the applicable indenture and any related documents before investing in our debt securities.

The prospectus supplement relating to any series of debt securities that we may offer will contain the specific terms of the debt securities. These terms may include the following:

7

General

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the indenture. Such additional notes will have the same terms as to ranking, redemption, waivers, amendments or otherwise as the applicable series of notes, and will vote together as one class on all matters with respect to such series of notes. In addition, we will describe in the applicable prospectus supplement, material U.S. federal tax considerations and any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars. Any taxes withheld or deducted from payments in respect of the debt securities and paid to the relevant tax authority shall be deemed to have been paid to the applicable holder. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

8

We expect most debt securities to be issued in fully registered form without coupons and in denominations of $2,000 and integral multiples of $1,000 in excess thereof. Subject to the limitations provided in the indenture and in the applicable prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the corporate office of the trustee or the principal corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

Book-Entry; Delivery and Settlement

Global Securities

Unless we inform you otherwise in the applicable prospectus supplement, the debt securities of a series will be represented by one or more global securities that will be deposited with and registered in the name of The Depository Trust Company (“DTC”) or its nominee for the accounts of its participants, including Euroclear Bank S.A./N.V. (“Euroclear”), as operator of the Euroclear System, and Clearstream Banking, société anonyme (“Clearstream”). We will not issue certificated notes, except in the limited circumstances described below. Transfers of ownership interests in the global securities will be effected only through entries made on the books of DTC participants acting on behalf of beneficial owners. You will not receive written confirmation from DTC of your purchase. The direct or indirect participants through whom you purchased the debt securities should send you written confirmations providing details of your transactions, as well as periodic statements of your holdings. The direct and indirect participants are responsible for keeping accurate account of the holdings of their customers like you. The laws of some states require that certain purchasers of debt securities take physical delivery of such debt securities in definitive form. Such limits and such laws may impair the ability to own, transfer or pledge beneficial interests in the global securities.

You, as the beneficial owner of debt securities, will not receive certificates representing ownership interests in the global securities, except in the following limited circumstances: (1) DTC notifies us that it is unwilling or unable to continue as depositary or if DTC ceases to be eligible under the indenture and we do not appoint a successor depositary within 90 days; (2) we determine that the debt securities will no longer be represented by global securities and execute and deliver to the trustee an officer’s certificate to such effect; or (3) an event of default with respect to the debt securities will have occurred and be continuing and you request securities in certificated or definitive form. These certificated securities will be registered in such name or names as DTC will instruct the trustee. It is expected that such instructions may be based upon directions received by DTC from participants with respect to ownership of beneficial interests in global securities.

DTC, Clearstream and Euroclear

DTC has advised us as follows:

9

Clearstream has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between its customers through electronic book-entry changes in accounts of its customers, thereby eliminating the need for physical movement of certificates. Clearstream provides to its customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Section. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream customer either directly or indirectly.

Euroclear has advised us that it was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities brokers and dealers, and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

The Euroclear Operator has advised us that it is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking and Finance Commission.

We have provided the descriptions of the operations and procedures of DTC, Clearstream and Euroclear in this prospectus solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of us, any underwriters or the trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC, Clearstream and Euroclear or their participants directly to discuss these matters.

So long as DTC or its nominee is the registered owner and holder of the global securities, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global securities for all purposes under the indenture relating to the debt securities. Except as provided above, you, as the beneficial owner of interests in the global securities, will not be entitled to have debt securities registered in your name, will not receive or be entitled to receive physical delivery of debt securities in definitive form and will not be considered the owner or holder thereof under the indenture. Accordingly, you, as the beneficial owner, must rely on the procedures of DTC and, if you are not a DTC participant, on the procedures of the DTC participants through which you own your interest, to exercise any rights of a holder under the indenture.

Neither we, the trustee, nor any other agent of ours or agent of the trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests

10

in global securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests. DTC’s practice is to credit the accounts of DTC’s direct participants with payment in amounts proportionate to their respective holdings in principal amount of beneficial interest in a debt security as shown on the records of DTC, unless DTC has reason to believe that it will not receive payment on the payment date. The underwriters will initially designate the accounts to be credited.

Beneficial owners may experience delays in receiving distributions on their debt securities because distributions will initially be made to DTC and they must be transferred through the chain of intermediaries to the beneficial owner’s account. Payments by DTC participants to you will be the responsibility of the DTC participant and not of DTC, the trustee or us. Accordingly, neither we, the trustee nor any paying agent will have any responsibility or liability for: any aspect of DTC’s records relating to, or payments made on account of, beneficial ownership interests in debt securities represented by a global securities certificate; any other aspect of the relationship between DTC and its participants or the relationship between those participants and the owners of beneficial interests in a global securities certificate held through those participants; or the maintenance, supervision or review of any of DTC’s records relating to those beneficial ownership interests.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

We have been informed that, under DTC’s existing practices, if we request any action of holders of debt securities, or an owner of a beneficial interest in a global security such as you desires to take any action which a holder of debt securities is entitled to take under the indenture, DTC would authorize the direct participants holding the relevant beneficial interests to take such action, and those direct participants and any indirect participants would authorize beneficial owners owning through those direct and indirect participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

Global Clearance and Settlement Procedures

Initial settlement for the debt securities will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, as applicable, and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving the debt securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their U.S. depositaries.

Because of time-zone differences, credits of the debt securities received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in the debt

11

securities settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of the debt securities by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures to facilitate transfers of the debt securities among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

Events of Default

Under the terms of the indenture, each of the following constitutes an event of default for a series of debt securities unless it is either inapplicable to a particular series or it is specifically deleted or modified:

We are required to furnish the trustee annually with an officer’s certificate as to our compliance with all conditions and covenants under the indenture. The indenture provides that the trustee may withhold notice to you of any default, except in respect of the payment of the principal of, premium, if any, or interest on the debt securities, if it considers it in the interest of the holders of the debt securities to do so.

Effect of an Event of Default

If an event of default exists with respect to a series of outstanding debt securities (other than an event of default in the case of certain events of bankruptcy), the trustee or the holders of not less than 25% in aggregate principal amount of such series of outstanding debt securities may declare the principal amount, or, if the debt securities are original issue discount securities, the portion of the principal amount as may be specified in the terms of that series, of and all accrued but unpaid interest on all outstanding debt securities of that series to be due and payable immediately, by a notice in writing to us, and to the trustee if given by holders. Upon that declaration the principal (or specified) amount will become immediately due and payable. However, at any time after a declaration of acceleration has been made, but before a judgment or decree for payment of the money due has been obtained, the event of default may, without further act, be deemed to have been waived and such declaration may, without further act, be deemed to have been rescinded and annulled subject to conditions specified in the indenture.

If an event of default in the case of certain events of bankruptcy, insolvency or reorganization exists, the principal amount of all debt securities outstanding under the indenture shall automatically, and without any declaration or other action on the part of the trustee or any holder of such outstanding debt, become immediately due and payable.

12

Subject to the provisions of the indenture relating to the duties of the trustee, if an event of default then exists, the trustee will be under no obligation to exercise any of its rights or powers under the indenture (other than the payment of any amounts on the debt securities furnished to it pursuant to the indenture) at your (or any other person’s) request, order or direction, unless you have (or such other person has) offered to the trustee security or indemnity satisfactory to it. Subject to the provisions for the security or indemnification of the trustee, the holders of a majority in aggregate principal amount of a series of outstanding debt securities 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 in connection with the debt securities of that series.

Legal Proceedings and Enforcement of Right to Payment

You will not have any right to institute any proceeding in connection with the indenture or for any remedy under the indenture, unless (i) you have previously given to the trustee written notice of a continuing event of default with respect to debt securities of that series, (ii) the holders of at least 25% in aggregate principal amount of a series of the outstanding debt securities must have made written request to the trustee to institute that proceeding, (iii) there shall have been offered to the trustee security or indemnity satisfactory to the trustee and (iv) the trustee, within 60 days following the receipt of that notice, must have failed to institute the proceeding. However, you will have an absolute and unconditional right to receive payment of the principal of, premium, if any, and interest on that debt security on or after the due dates expressed in the debt security and to institute a suit for the enforcement of that payment.

Modification and Waiver

Modification

We and the trustee may modify and amend the indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each series affected. However, no modification or amendment may, without the consent of the holder of each outstanding debt security affected:

13

Waiver

The holders of a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of the holders of all debt securities of that series, waive compliance by us with certain restrictive covenants of the indenture.

The holders of a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of the holders of all debt securities of that series, generally waive any past default under the indenture and the consequences of such default. However, a default in the payment of the principal of, or premium, if any, or any interest on, any debt security of that series or a default in respect of a covenant or provision of the indenture that cannot be modified or amended without the consent of the holder of each outstanding debt security affected cannot be so waived.

Merger, Consolidation and Sale of Assets

We will not consolidate with or merge into any other entity, or sell other than for cash or lease, all or substantially all our assets to another entity, and no entity may consolidate with or merge into us, unless:

Redemption and Repayment

Unless we specify otherwise in an accompanying prospectus supplement, the debt securities will not be redeemable prior to their stated maturity. If we so specify in an accompanying prospectus supplement, the debt security will be redeemable on or after the date or dates set forth in such supplement, either in whole or from time to time in part, at our option, at the redemption price set forth in such prospectus supplement. We will pay interest accrued on a redeemed debt security to, but not including, the date of redemption, and will give notice of redemption no more than 60 and not less than 30 days prior to the date of redemption. The debt securities will not be subject to any sinking fund or to any provisions for repayment at your option unless we specify otherwise in an accompanying prospectus supplement.

Defeasance and Covenant Defeasance

The indenture provides that we may discharge all of our obligations with respect to any series of the debt securities at any time, and that we may also be released from our obligations under certain covenants and from certain other obligations, including obligations imposed by a company order or supplemental indenture with respect to that series, if any, and elect not to comply with those sections and obligations without creating an event of default. Discharge under the first procedure is called “defeasance” and under the second procedure is called “covenant defeasance.”

Defeasance or covenant defeasance may be effected only if:

14

Governing Law

The indenture and the debt securities shall be governed by and construed in accordance with the laws of the State of New York.

Concerning the Trustee

The trustee under the indenture is The Bank of New York Mellon Trust Company, N.A. The trustee will have all the duties and responsibilities of an indenture trustee specified in the Trust Indenture Act with respect to any debt securities issued under the indenture. The trustee is not required to expend or risk its own funds or otherwise incur financial liability in performing its duties or exercising its rights and powers if it reasonably believes that it is not reasonably assured of repayment or adequate indemnity.

DESCRIPTION OF CAPITAL STOCK

General

We may offer shares of our Class A Common Stock, Class C Capital Stock or shares of our preferred stock. The following summary of the rights of our capital stock does not purport to be complete.

Our certificate of incorporation provides for (1) the Class A Common Stock (“Class A Common Stock”), which has one vote per share; (2) the Class B Common Stock (“Class B Common Stock”), which has 10 votes per share; and (3) the Class C Capital Stock (“Class C Capital Stock”), which has no voting rights unless otherwise required by law. Our certificate of incorporation also provides for 100,000,000 shares of preferred stock.

Our authorized capital stock consists of 300,100,000,000 shares, each with a par value of $0.001 per share, of which:

As of April 17, 2025, there were 5,820 million shares of Class A Common Stock issued and outstanding, 856 million shares of Class B Common Stock issued and outstanding and 5,459 million shares of Class C Capital Stock issued and outstanding.

Voting Rights

Holders of shares of Class A Common Stock and Class B Common Stock have identical rights, except that holders of shares of Class A Common Stock are entitled to one vote per share and holders of shares of Class B Common Stock are entitled to 10 votes per share.

Each share of Class B Common Stock is convertible at any time at the option of the holder into one share of Class A Common Stock upon written notice to our transfer agent. In addition, each share of Class B Common Stock shall convert automatically into one share of Class A Common Stock upon any transfer, whether or not for value, except for certain transfers described in our certificate of incorporation, including the following:

In addition, partnerships or limited liability companies that held more than 5% of the total outstanding shares of Class B Common Stock as of the closing of Google’s initial public offering in 2004 may distribute their shares of Class B Common Stock to their respective partners or members (who may further distribute the shares

17

of Class B Common Stock to their respective partners or members) without triggering a conversion to shares of Class A Common Stock. Such distributions must be conducted in accordance with the ownership interests of such partners or members and the terms of any agreements binding the partnership or limited liability company.

The death of any holder of shares of Class B Common Stock who is a natural person will result in the conversion of his or her shares of Class B Common Stock, and any shares held by his or her permitted entities, into shares of Class A Common Stock. However, subject to the terms of the Transfer Restriction Agreements, either of Larry or Sergey may transfer voting control of his shares of Class B Common Stock and those held by his permitted entities to the other contingent or effective upon his death without triggering a conversion into shares of Class A Common Stock, but the shares of Class B Common Stock so transferred will convert to Class A Common Stock nine months after the death of the transferring founder.

Once transferred and converted into shares of Class A Common Stock, shares of Class B Common Stock shall not be reissued.

No class of our capital stock may be subdivided or combined unless the other classes of capital stock are concurrently subdivided or combined in the same proportion and in the same manner.

Equal Status

Except as expressly provided in our certificate of incorporation, shares of Class A Common Stock and Class B Common Stock have the same rights and privileges and rank equally, share ratably and are identical in all respects as to all matters. In the event of any merger, consolidation, or other business combination requiring the approval of our stockholders entitled to vote thereon (whether or not we are the surviving entity), the holders of shares of Class A Common Stock shall have the right to receive, or the right to elect to receive, the same form of consideration as the holders of shares of Class B Common Stock, and the holders of shares of Class A Common Stock shall have the right to receive, or the right to elect to receive, at least the same amount of consideration on a per share basis as the holders of shares of Class B Common Stock. In the event of any (1) tender or exchange offer to acquire any shares of Class A Common Stock or Class B Common Stock by any third party pursuant to an agreement to which we are a party, or (2) any tender or exchange offer by us to acquire any shares of Class A Common Stock or Class B Common Stock, the holders of shares of Class A Common Stock shall have the right to receive, or the right to elect to receive, the same form of consideration as the holders of shares of Class B Common Stock, and the holders of shares of Class A Common Stock shall have the right to receive, or the right to elect to receive, at least the same amount of consideration on a per share basis as the holders of shares of Class B Common Stock.

Except as expressly provided in our certificate of incorporation, shares of Class C Capital Stock have the same rights and privileges and rank equally, share ratably and are identical in all respects to the shares of Class A Common Stock and Class B Common Stock as to all matters. In the event of any merger, consolidation, or other business combination requiring the approval of our stockholders entitled to vote thereon (whether or not we are the surviving entity), the holders of shares of Class C Capital Stock shall receive the same amount and form of consideration on a per share basis as the consideration, if any, received by holders of shares of Class A Common Stock in connection with such merger, consolidation or combination (and if holders of shares of Class A Common Stock are entitled to make an election as to the amount or form of consideration that such holders shall receive in any such merger, consolidation or combination with respect to their shares of Class A Common Stock, then the holders of shares of Class C Capital Stock shall be entitled to make the same election as to their shares of Class C Capital Stock). In the event of any (1) tender or exchange offer to acquire any shares of Class A Common Stock or Class B Common Stock by any third party pursuant to an agreement to which we are a party, or (2) any tender or exchange offer by us to acquire any shares of Class A Common Stock or Class B Common Stock, the holders of shares of Class C Capital Stock shall receive the same amount and form of consideration on a per share basis as the consideration received by holders of shares of Class A Common Stock (and if holders of shares of Class A Common Stock are entitled to make an election as to the amount or form of consideration that

18

such holders shall receive in any such tender or exchange offer with respect to their shares of Class A Common Stock, then the holders of shares of Class C Capital Stock shall be entitled to make the same election as to their shares of Class C Capital Stock).

Class C Settlement Agreement

In connection with the adjustment of Google’s capital structure by establishing the Google Class C Capital Stock, and the dividend of one share of Google Class C Capital Stock for each share of Google Class A Common Stock and Google Class B Common Stock outstanding on March 27, 2014 (the “Class C dividend”), on October 28, 2013, the Delaware Court of Chancery approved a settlement entered into by Google, the board of directors of Google and the plaintiffs in the class action litigation involving the authorization to distribute Google Class C Capital Stock captioned In Re: Google Inc. Class C Shareholder Litigation, Civil Action No. 7469-CS. The parties subsequently filed a Revised Stipulation of Compromise and Settlement with the Court, which issued an Order and Final Judgment on November 6, 2013 that fully approved the parties’ settlement agreement (the “Google Class C Settlement Agreement”). Additionally, on October 2, 2015, we entered into a Class C Undertaking pertaining to the Google Class C Settlement Agreement, pursuant to which Alphabet will undertake, with respect to the Alphabet Class A Common Stock, Class B Common Stock, Class C Capital Stock and preferred stock, to be bound by the restrictions, undertakings and all continuing obligations and to benefit from the rights of the Google Class C Settlement Agreement that are applicable to Google as if Alphabet were Google (the “Class C Undertaking”).

The terms of the Class C Undertaking require us to: (i) ensure that the Transfer Restriction Agreements (defined below) entered into by Larry, our Co-Founder and director; Sergey, our Co-Founder and director; and Eric E. Schmidt, a significant stockholder, and certain of their respective affiliates cannot be waived or amended unless such amendment or waiver is first considered and recommended by a committee of two or more of the independent directors of our board of directors who do not hold Class B Common Stock, and then approved by every member of our board of directors, excluding Larry and Sergey; (ii) ensure that any waiver or amendment of the Transfer Restriction Agreements will be publicly disclosed at least 30 days before such waiver or amendment takes effect on a Form 8-K, Form 10-Q or Form 10-K; (iii) effective for three years from the Class C Capital Stock dividend payment date, prior to issuing more than 10 million shares of Class C Capital Stock as consideration in an acquisition or other business combination (excluding assumptions or conversions of equity for employees of acquired or combined companies), have our independent directors consider the effects of issuing such shares on our holders of Class A Common Stock and upon the company as a whole; and (iv) when the aggregate voting power of Larry and Sergey falls below 15% of the cumulative voting power of all our shareholders, have our board of directors consider in good faith whether it is no longer in our best interests to maintain a class of nonvoting stock and, if it so determines, take steps to cause the Class C Capital Stock to convert into Class A Common Stock.

Transfer Restriction Agreements

On October 2, 2015, we entered into a transfer restriction agreement with each of Larry, Sergey, Eric and certain of their respective affiliates (collectively, the “Transfer Restriction Agreements”). On December 31, 2021, we entered into a joinder to Sergey’s transfer restriction agreement with certain of his other affiliates. The Transfer Restriction Agreements are intended to limit the ability of Larry, Sergey, and Eric to sell their Alphabet stock in a manner that does not reduce their voting power. Under the Transfer Restriction Agreements, the parties are bound, without any modification, by the same restrictions, undertakings and obligations that are imposed under the transfer restriction agreements, related joinders and other documentation entered into with Google on March 25, 2014 in connection with the Google Class C Settlement Agreement (the “Google Transfer Restriction Agreements”).

Pursuant to the Transfer Restriction Agreements, none of Larry, Sergey, Eric, or certain of their respective affiliates that are party to the agreements (generally, trusts and other estate planning vehicles through which Larry, Sergey, and Eric hold all or a portion of their shares of Class A Common Stock, Class B Common Stock or Class C Capital Stock) may sell, assign, transfer, convey or hypothecate any shares of Class C Capital Stock if,

19

as a result of such sale, transfer, conveyance or hypothecation, they, together with certain of their respective affiliates, would own more shares of Class B Common Stock than shares of Class C Capital Stock. If at any time either Larry, Sergey, or Eric, in each case together with certain of his respective affiliates, owns more shares of Class B Common Stock than shares of Class C Capital Stock, then Larry, Sergey, or Eric, as the case may be, and his respective affiliates, will be deemed to have automatically converted that number of shares of Class B Common Stock into shares of Class A Common Stock such that after such conversion he and his affiliates own an equal number of shares of Class B Common Stock as he and his affiliates own of shares of Class C Capital Stock. The required maximum ratio of shares of Class B Common Stock to shares of Class C Capital Stock owned by Larry, Sergey and Eric is subject to adjustment in connection with certain dividends, stock splits, distributions or recapitalizations.

Larry, Sergey, Eric, and certain of their respective affiliates that are party to the Transfer Restriction Agreements may transfer shares of Class B Common Stock to their affiliates as permitted by the terms of our certificate of incorporation only if, immediately following such transfer, Larry, Sergey, or Eric, as the case may be, and his respective affiliates, would own an aggregate number of shares of Class B Common Stock equal to or less than the number of shares of Class C Capital Stock that he and his affiliates own. Additionally, Larry, Sergey, Eric, and certain of their respective affiliates that are party to the Transfer Restriction Agreements may transfer shares of Class C Capital Stock to their affiliates only if, immediately following such transfer, Larry, Sergey, or Eric, as the case may be, and his respective affiliates, would own an aggregate number of shares of Class B Common Stock equal to or less than the number of shares of Class C Capital Stock that he and his affiliates own. However, each of Larry and his affiliates that are party to his Transfer Restriction Agreement and Sergey and his affiliates that are party to his Transfer Restriction Agreement may not transfer shares of Class B Common Stock to another person in a transfer that does not result in the automatic conversion of such shares of Class B Common Stock into Class A Common Stock pursuant to the terms of the certificate of incorporation unless Larry or Sergey, as the case may be, and his respective affiliates, transfer, in the same manner and to the same extent, an equal number of shares of Class C Capital Stock to the transferee.

In the event of (1) any merger, consolidation, or other business combination requiring the approval of the holders of our capital stock (whether or not Alphabet is the surviving entity), or the acquisition of all or substantially all of our assets, (2) any tender or exchange offer by any third party to acquire a majority of the shares of Class A Common Stock, Class B Common Stock or Class C Capital Stock, or (3) any tender or exchange offer by us to acquire any shares of Class A Common Stock, Class B Common Stock, or Class C Capital Stock, none of Larry, Sergey, Eric, and certain of their respective affiliates that are party to the Transfer Restriction Agreements may sell, transfer or exchange, directly or indirectly, any shares of Class A Common Stock, Class B Common Stock, or Class C Capital Stock in connection with such transaction or in a related transaction for (a) with respect to their shares of Class A Common Stock or Class B Common Stock, an amount per share greater than the holders of shares of Class A Common Stock receive in such transaction or a form of consideration different from the form that the holders of shares of Class A Common Stock would receive, or may elect to receive, in such transaction; or (b) with respect to their shares of Class C Capital Stock, an amount per share greater than the holders of shares of Class C Capital Stock receive in such transaction or a form of consideration different from the form that the holders of shares of Class C Capital Stock would receive, or may elect to receive, in such transaction (the “Founder Equal Treatment Provision”).

With respect to Larry, Sergey, and certain of their respective affiliates, the applicable Transfer Restriction Agreements generally terminate when they collectively hold less than 34% of our total outstanding voting power. However, the Founder Equal Treatment Provision never terminates.

With respect to Eric and certain of his affiliates, the applicable Transfer Restriction Agreement generally terminates when they collectively hold less than 2% of our total outstanding voting power. However, the Founder Equal Treatment Provision never terminates.

As required under the terms of the Class C Settlement Agreement, the Transfer Restriction Agreements may only be amended or waived if such amendment or waiver is (i) first considered and recommended by a

20

committee of two or more independent directors of our board of directors who do not hold Class B Common Stock and (ii) then approved by every member of our board of directors, excluding Larry and Sergey. Any Transfer Restriction Agreement amendment or waiver will be publicly disclosed by Alphabet on a Form 8-K, Form 10-Q or Form 10-K at least 30 days before such amendment or waiver takes effect.

Preferred Stock

We are authorized to issue, without approval by our stockholders, up to a total of 100,000,000 shares of preferred stock in one or more series. Our board of directors may establish the number of shares to be included in each such series and may fix the designations, preferences, powers, and other rights, and any qualifications, limitations or restrictions of the shares of a series of preferred stock. Our board of directors could authorize the issuance of preferred stock with voting or conversion rights that could dilute the voting power or rights of the holders of Class A Common Stock, Class B Common Stock, and Class C Capital Stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of Alphabet and might harm the market price of our Class A Common Stock or Class C Capital Stock.

The particular terms of any series of preferred stock offered by us will be described in the prospectus supplement relating to that series of preferred stock. Those terms relating to the series of preferred stock offered may include:

Holders of preferred stock will be entitled to receive, when, as and if declared by our board of directors, cash dividends at the rates and on the dates set forth in the related prospectus supplement. Dividend rates may be fixed or variable or both. Different series of preferred stock may be entitled to dividends at different dividend rates or based upon different methods of determination. Each dividend will be payable to the holders of record as they appear on our stock books on record dates determined by our board of directors. Dividends on preferred stock may be cumulative or noncumulative, as specified in the related prospectus supplement. If our board of directors fails to declare a dividend on any preferred stock for which dividends are noncumulative, then the right to receive that dividend will be lost, and we will have no obligation to pay the dividend for that dividend period, whether or not dividends are declared for any future dividend period.

Any series of preferred stock may be redeemable in whole or in part at our option. In addition, any series of preferred stock may be subject to mandatory redemption pursuant to a sinking fund. The redemption provisions that may apply to a series of preferred stock, including the redemption dates and the redemption prices for that series, will be set forth in the related prospectus supplement.

21

Anti-Takeover Effects of Our Certificate of Incorporation and Bylaws and of Delaware Law

Certain provisions of our certificate of incorporation and bylaws and of the DGCL could have the effect of delaying, deferring, or discouraging another party from acquiring control of us. In particular, our capital structure concentrates ownership of our voting stock in the hands of Larry, Sergey, and Eric. These provisions, which are summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. However, these provisions could also have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our Class A Common Stock or Class C Capital Stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Three Classes of Stock

As discussed above, our Class B Common Stock has 10 votes per share, while our Class A Common Stock has one vote per share and our Class C Capital Stock has no voting rights (unless otherwise required by law). As a result of their ownership of a substantial portion of our Class B Common Stock, Larry and Sergey currently have the ability to elect all of our directors and to determine the outcome of most matters submitted for a vote of our stockholders. This concentrated voting control could discourage others from initiating any potential merger, takeover, or other change of control transaction that other stockholders may view as beneficial.

Because the Class C Capital Stock has no voting rights (except as required by law), the issuance of Class C Capital Stock will not result in voting dilution to the holders of shares of Class A Common Stock or Class B Common Stock. As a result, the issuance of Class C Capital Stock could prolong the duration of Larry and Sergey’s current relative ownership of our voting power and their ability to elect all of our directors and to determine the outcome of most matters submitted to a vote of our stockholders.

So long as Larry and Sergey have the ability to determine the outcome of most matters submitted to a vote of our stockholders, third parties may be deterred in their willingness to make an unsolicited merger, takeover, or other change of control proposal, or to engage in a proxy contest for the election of directors. As a result, our three classes of stock may have the effect of depriving our stockholders of an opportunity to sell their shares at a premium over prevailing market prices and make it more difficult to replace our directors and management.

Special Approval for Change in Control Transactions

In the event a person seeks to acquire us by means of a merger or consolidation transaction, a purchase of all or substantially all of our assets, or an issuance of our voting securities representing more than 2% of our outstanding shares at the time of issuance and that results in any person or group owning more than 50% of our outstanding voting power, then these types of acquisition transactions must be approved by our stockholders at an annual or special meeting. At this meeting, we must obtain the approval of stockholders representing the greater of:

Limits on Ability of Stockholders to Act by Written Consent

We have provided in our certificate of incorporation and bylaws that our stockholders may not act by written consent. This limit on the ability of our stockholders to act by written consent may lengthen the amount of time required to take stockholder actions. As a result, no stockholder, regardless of how large its holdings of our stock are, would be able to amend our bylaws or remove directors without holding a stockholders meeting.

22

Undesignated Preferred Stock

The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to acquire us. These and other provisions may have the effect of deferring or preventing hostile takeovers or delaying or preventing changes in control or management of our company.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors or a committee of our board of directors. The bylaws do not give our board of directors the power to approve or disapprove stockholder nominations of candidates or proposals regarding business to be conducted at a special or annual meeting of the stockholders. However, our bylaws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company.

Delaware Anti-Takeover Statute

We are subject to Section 203 of the DGCL regulating corporate takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder unless:

Generally, a business combination includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who owns 15% or more of a corporation’s outstanding voting securities or is an affiliate or associate of the corporation and, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting securities, and affiliates and associates of such person. The existence of this provision may have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. Section 203 may also discourage attempts that might result in a premium over the market price for the shares of capital stock held by stockholders.

Transfer Agent and Registrar

The transfer agent and registrar for our capital stock is Computershare Trust Company, N.A., P.O. Box 43078, Providence, Rhode Island 02940-3078. Overnight correspondence should be sent to: Computershare Trust Company, N.A., 150 Royall Street, Suite 101 Canton, Massachusetts 02021.

Our Class C Capital Stock and Class A Common Stock are listed on The NASDAQ Global Select Market under the symbols “GOOG” and “GOOGL” respectively. Our Class B Common Stock is not listed on any stock market or exchange.

DESCRIPTION OF WARRANTS

General

We may offer warrants, including warrants to purchase debt securities, preferred stock, Class A Common Stock, Class C Capital Stock or other securities, property or assets (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), as well as other types of warrants. We may offer warrants independently or together with other securities offered under this prospectus, and they may be attached to or separate from those securities. We will issue the warrants under one or more warrant agreements between us and a bank or trust company, as warrant agent, that we will describe in the prospectus supplement relating to the warrants we offer.

The following is a summary of certain general terms and provisions of the warrants, but they are not complete and are subject to, and are qualified in their entirety by reference to, the warrant agreement and the warrant certificate relating to the warrants. Forms of these documents will be filed as exhibits to the registration statement of which this prospectus is a part, either by an amendment to the registration statement or by a Current Report on Form 8-K. See “Where You Can Find More Information” for information on how to obtain copies of these documents. You should read the summary below, the applicable prospectus supplement and the provisions of the warrant agreement and the warrant certificate before investing in our warrants.

Debt Warrants

We will describe in the applicable prospectus supplement the terms of warrants to purchase debt securities that we may offer, the warrant agreement relating to the debt warrants and the warrant certificates representing the debt warrants. These terms will include the following:

We will also describe in the applicable prospectus supplement any provisions for a change in the exercise price or expiration date of the warrants and the kind, frequency and timing of any notice to be given. You may

25

exchange debt warrant certificates for new debt warrant certificates of different denominations and may exercise debt warrants at the corporate trust office of the warrant agent or any other office that we indicate in the applicable prospectus supplement. Prior to exercise, you will not have any of the rights of holders of the debt securities purchasable upon that exercise and will not be entitled to payments of principal, premium, if any, or interest on the debt securities purchasable upon the exercise.

Other Warrants

We may issue other warrants. We will describe in the applicable prospectus supplement the following terms of those warrants:

We will also describe in the applicable prospectus supplement any provisions for a change in the exercise price or the expiration date of the warrants and the kind, frequency and timing of any notice to be given. You may exchange warrant certificates for new warrant certificates of different denominations and may exercise warrants at the corporate trust office of the warrant agent or any other office that we indicate in the applicable prospectus supplement. Prior to the exercise of your warrants, you will not have any of the rights of holders of the preferred stock, common stock or other securities purchasable upon that exercise and will not be entitled to dividend payments, if any, or voting rights of the preferred stock, common stock or other securities purchasable upon the exercise.

Exercise of Warrants

We will describe in the prospectus supplement relating to the warrants the principal amount or the number of our securities, or amount of other securities, property or assets that you may purchase for cash upon exercise of a warrant, and the exercise price. You may exercise a warrant as described in the prospectus supplement

26

relating to the warrants at any time up to the close of business on the expiration date stated in the prospectus supplement. Unexercised warrants will become void after the close of business on the expiration date, or any later expiration date that we determine.

We will forward the securities purchasable upon the exercise as soon as practicable after receipt of payment and the properly completed and executed warrant certificate at the corporate trust office of the warrant agent or other office stated in the applicable prospectus supplement. If you exercise less than all of the warrants represented by the warrant certificate, we will issue you a new warrant certificate for the remaining warrants.

27

PLAN OF DISTRIBUTION

Initial Offering and Sale of Securities

We may sell securities from time to time in one or more transactions separately or in combination. We may sell the securities of or within any series to or through agents, underwriters, dealers, remarketing firms or other third parties or directly to one or more purchasers or through a combination of any of these methods. We may issue securities as a dividend or distribution. In some cases, we or dealers acting with us or on behalf of us may also purchase securities and reoffer them to the public. We may also offer and sell, or agree to deliver, securities pursuant to, or in connection with, any option agreement or other contractual arrangement.

Agents whom we designate may solicit offers to purchase the securities.

We may use an underwriter or underwriters in the offer or sale of the securities.

We may use a dealer to sell the securities.

We may solicit directly offers to purchase the securities, and we may directly sell the securities to institutional or other investors. We will describe the terms of direct sales in the applicable prospectus supplement.

We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) of the Securities Act.

We may also offer and sell securities, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms referred to as remarketing firms, acting as principals for their own accounts or as our agents. Any remarketing firm will be identified and the terms of its agreement, if any, with us, and its compensation will be described in the applicable prospectus supplement. Remarketing firms may be deemed to be underwriters under the Securities Act in connection with the securities they remarket.

28

We may indemnify agents, underwriters, dealers and remarketing firms against certain liabilities, including liabilities under the Securities Act. Agents, underwriters, dealers and remarketing firms, or their affiliates, may be customers of, engage in transactions with or perform services for us or our respective affiliates, in the ordinary course of business.

We may authorize agents and underwriters to solicit offers by certain institutions to purchase the securities at the public offering price under delayed delivery contracts.

Any underwriter, agent or dealer that is a Financial Industry Regulatory Authority member is not permitted to sell securities in an offering to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

Unless otherwise specified in connection with a particular underwritten offering of securities, the underwriters will not be obligated to purchase offered securities unless specified conditions are satisfied, and if the underwriters do purchase any offered securities, they will purchase all offered securities.

In connection with underwritten offerings of the offered securities and in accordance with applicable law and industry practice, the underwriters in certain circumstances are permitted to engage in certain transactions that stabilize the price of the securities. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the securities. If the underwriters create a short position in the securities in connection with the offering (i.e., if they sell more securities than are set forth on the cover page of the applicable prospectus supplement), the underwriters may reduce that short position by purchasing securities in the open market or as otherwise provided in the applicable prospectus supplement. The underwriters also may impose a penalty bid on certain underwriters. This means that if the underwriters purchase the securities in the open market to reduce the underwriters’ short position or to stabilize the price of the securities, they may reclaim the amount of the selling concession from the underwriters who sold those securities as part of the offering. In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of a security to the extent that it were to discourage resales of the security. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We may enter into derivative or other hedging transactions involving the securities with third parties, or sell securities not covered by the prospectus to third parties in privately-negotiated transactions. If we so indicate in the applicable prospectus supplement, in connection with those derivative transactions, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions, or may lend securities in order to facilitate short sale transactions by others. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivative or hedging transactions to close out any related open borrowings of securities. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment to the registration statement that includes this prospectus).

We may effect sales of securities in connection with forward sale, option or other types of agreements with third parties. Any distribution of securities pursuant to any forward sale agreement may be effected from time to

29

time in one or more transactions that may take place through a stock exchange, including block trades or ordinary broker’s transactions, or through broker-dealers acting either as principal or agent, or through privately-negotiated transactions, or through an underwritten public offering, or through a combination of any such methods of sale, at market prices prevailing at the time of sale, at prices relating to such prevailing market prices or at negotiated or fixed prices.

We may loan or pledge securities to third parties that in turn may sell the securities using this prospectus and the applicable prospectus supplement or, if we default in the case of a pledge, may offer and sell the securities from time to time using this prospectus and the applicable prospectus supplement. Such third parties may transfer their short positions to investors in the securities or in connection with a concurrent offering of other securities offered by this prospectus and the applicable prospectus supplement or otherwise.

Sales by Selling Security Holders

Selling security holders may use this prospectus in connection with resales of securities they hold as described in the applicable prospectus supplement. The applicable prospectus supplement will identify the selling security holders, the terms of the securities and any material relationships we have with the selling security holders. Selling security holders may be deemed to be underwriters under the Securities Act in connection with the securities they resell and any profits on the sales may be deemed to be underwriting discounts and commissions under the Securities Act. Unless otherwise provided in a prospectus supplement, the selling security holders will receive all the proceeds from the sale of the securities.

30
