For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (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. 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. This prospectus supplement has been prepared on the basis that any offer of notes in any member state of the EEA will be made pursuant to an exemption under Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”) from the requirement to publish a prospectus for offers of notes. Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Regulation.

Any person subsequently offering, selling or recommending the notes (a “distributor”) should take into consideration the manufacturer’s 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 manufacturer’s target market assessment) and determining appropriate distribution channels.

Risk Factors

You should carefully consider the specific factors set forth under “Risk Factors” on page S-6 of this prospectus supplement as well as the information and data included elsewhere or incorporated by reference in this prospectus supplement or the accompanying prospectus, before making an investment decision.

S-5

RISK FACTORS

Investing in our securities involves risks. Prior to making a decision about investing in our securities, in addition to the other information contained or incorporated by reference in this prospectus supplement, you should carefully consider the risks described in the section entitled “Risk Factors” in any other prospectus supplement and the risks described in our most recent Annual Report on Form 10-K, which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The occurrence or realization of any of these risks could materially adversely affect our business, operating results and financial condition.

The risks and uncertainties we describe are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business or operations. Any adverse effect on our business, financial condition or operating results could result in a decline in the value of our securities and the loss of all or part of your investment.

There is currently no trading market for the notes and an active trading market for the notes may not develop.

The notes are new issues of securities with no established trading market, and we do not intend to list them on any securities exchange or automated quotation system. As a result, an active trading market for the notes may not develop, or if one does develop, it may not be sustained. If an active trading market fails to develop or cannot be sustained, you may not be able to resell your notes at their fair market value or at all.

Increases in prevailing interest rates could adversely impact the trading price for the notes.

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, and increases in prevailing interest rates could have an adverse effect on the trading price of the notes.

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 yen.

Investors will have to pay for the notes in yen. Principal and interest payments on the notes, including payments upon any redemption of the notes, are payable by us in yen. An investment in the notes which are denominated in, and all payments in respect of which are to be made in, a currency other than the currency of the country in which the purchaser is resident or the currency in which the purchaser conducts its business or activities (the home currency), entails significant risks not associated with a similar investment in a security denominated in the home currency. These include the possibility of:

•

significant changes in rates of exchange between the holder’s home currency and the yen;

•

the imposition or modification of foreign exchange controls with respect to the yen; and

•

tax consequences for you as a result of any foreign exchange gains resulting from an investment in the notes.

We have no control over a number of factors affecting this type of note, including economic, financial and political events that are important in determining the existence, magnitude and longevity of these risks and their results. In recent years, rates of exchange for certain currencies, including the yen, have been highly volatile, and this volatility may be expected to continue in the future.

S-6

Fluctuations in any particular exchange rate that have occurred in the past are not necessarily indicative of fluctuations in the rate that may occur during the term of the notes. Depreciation of the yen against the holder’s home currency could result in a decrease in the effective yield of the notes below the applicable coupon rate, and in certain circumstances, could result in a loss to the holder on a home currency basis.

This description of foreign currency risks does not describe all the risks of an investment in securities denominated in a currency other than the home currency. You should consult your own financial 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 yen.

If the yen is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control then all payments in respect of the notes will be made in U.S. dollars until the yen is again available to us. The amount payable on any date in yen 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 then most recent U.S. dollar/yen exchange rate published in the Wall Street Journal on or prior to the second business day prior to the relevant payment date or, in the event the Wall Street Journal has not published such exchange rate, the rate will be determined in our sole discretion on the basis of the most recently available market exchange rate for yen. 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.

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 yen. 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 long time. A federal court in New York presiding over a dispute arising in connection with the notes may apply the foregoing New York law or in certain circumstances may render the judgment in U.S. dollars.

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 yen 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 ¥100,000,000 and multiples of ¥10,000,000 in excess thereof. It is possible that the clearing systems may process trades which 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 ¥10,000,000 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.

The global notes are held by or on behalf of Euroclear and Clearstream and, therefore, holders of the notes will have to rely on their procedures for transfer, payment and communication with us.

S-7

The notes will be represented by the global notes which will be held with a common depositary for Euroclear and Clearstream. Except in certain limited circumstances, holders of the notes will not be entitled to receive certificated notes in exchange for interests in the global notes. While the notes are represented by the global notes, holders of the notes will be able to trade their beneficial interests only through Euroclear and Clearstream.

We will discharge our payment obligations under the notes by making payments to or to the order of the common depositary for Euroclear and Clearstream for distribution to their accountholders. A holder of a beneficial interest in a global note must rely on the procedures of Euroclear and Clearstream to receive payments under the notes. We have no responsibility or liability for the records relating to, or payments made in respect of, beneficial interests in the global notes.

Holders of beneficial interests in the global notes will not have a direct right to vote in respect of the notes. Instead, such holders will be permitted to act directly only to the extent that they are enabled in accordance with the procedures of Euroclear and Clearstream to appoint appropriate proxies.

S-8

CURRENCY CONVERSION

All payments of interest and principal, including payments made upon any redemption of the notes, will be made in yen. If the yen is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control, then all payments in respect of the notes will be made in U.S. dollars until the yen is again available to us or so used. The amount payable on any date in yen 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 then most recent U.S. dollar/yen exchange rate published in the Wall Street Journal on or prior to the second business day prior to the relevant payment date or, in the event the Wall Street Journal has not published such exchange rate, the rate will be determined in our sole discretion on the basis of the most recently available market exchange rate for the yen. 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.

On March 27, 2026, the yen/U.S. dollar exchange rate was ¥160.1600 = U.S. $1.00, as announced by the U.S. Federal Reserve Board.

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

DESCRIPTION OF THE NOTES

The following description of certain material terms of the notes does not purport to be complete.

This description of the notes is intended to be an overview of the material provisions of the notes and is intended to supplement, and to the extent of any inconsistency replace, the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus, to which we refer you. The notes will be issued under an indenture, dated as of January 31, 2025 (the “indenture”), among us, Berkshire Hathaway Finance Corporation and The Bank of New York Mellon Trust Company, N.A., a national banking association, as trustee (the “trustee”). The Bank of New York Mellon, London Branch, will initially act as paying agent for the notes. The Bank of New York Mellon Trust Company, N.A., will initially act as security registrar and transfer agent for the notes. Since this description of the notes is only a summary, we urge you to read the indenture (including definitions of terms used therein) and the forms of notes because they, and not this description, define your rights as a beneficial owner of the notes. You may request copies of these documents from us at 3555 Farnam Street, Omaha, Nebraska 68131. The indenture and the forms of the notes are included or incorporated by reference as an exhibit to the registration statement of which this prospectus supplement forms a part.

General

Each series of notes offered by this prospectus supplement will be issued as a separate series under the indenture. Each series of notes will be our senior unsecured obligations and will be initially limited in aggregate principal amount to ¥ in the case of the % Senior Notes due ; ¥ in the case of the % Senior Notes due ; and ¥ in the case of the % Senior Notes due .

We may at any time, without notice to or consent of the holders of the notes offered by this prospectus supplement, issue additional notes of the same series as any series of notes offered hereby. Any such additional notes will have the same ranking, interest rate, maturity date and other terms as such series of notes offered hereby, except for possible variations permitted under the indenture. We intend to treat any such additional notes, together with the notes of the applicable series offered hereby, as a single series of notes under the indenture. If the additional notes, if any, are not fungible with the notes of the applicable series offered hereby for U.S. federal income tax purposes, the additional notes will have separate CUSIP, Common Code and ISIN numbers.

Unless earlier redeemed, the entire principal amount of the % Senior Notes due will mature and become due and payable, together with any accrued and unpaid interest thereon, on . Unless earlier redeemed, the entire principal amount of the % Senior Notes due will mature and become due and payable, together with any accrued and unpaid interest thereon, on . Unless earlier redeemed, the entire principal amount of the % Senior Notes due will mature and become due and payable, together with any accrued and unpaid interest thereon, on .

Each series of notes will be evidenced by one or more global notes deposited with the common depositary and registered in the name of the common depositary or its nominee. Except as described herein, beneficial interests in the global notes will be shown on, and transfers thereof will be effected only through, records maintained by Clearstream or Euroclear and their participants. See “ —Book-Entry Delivery and Form.”

You will not have the right to cause us to repurchase the notes in whole or in part at any time before they mature. The notes are not subject to a sinking fund provision.

Interest

The % Senior Notes due will accrue interest at a rate of % per annum. The % Senior Notes due will accrue interest at a rate of % per annum. The % Senior Notes due will accrue interest at a

S-11

rate of % per annum. Each series of notes offered by this prospectus supplement will accrue interest on its stated principal amount from , 2026, or from the most recent date to which interest has been paid or duly provided for. Accrued and unpaid interest on each series of notes will be payable semi-annually in arrears on and of each year, which we refer to as “interest payment dates,” commencing on , 2026.

Interest on each series of notes will be paid to the person in whose name a note is registered at the close of business on the and (whether or not a business day), which we refer to as “record dates,” immediately preceding the relevant interest payment date.

The amount of interest payable on each series of notes for any full semi-annual interest period will be computed on the basis of a 360-day year of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual interest period for which interest is computed will be computed on the basis of 30-day months and, for periods of less than a month, the actual number of days elapsed per 30-day month. If any date on which interest is payable on the notes is not a business day, then payment of the interest payable on such date will be made on the next succeeding day that is a business day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on such interest payment date. For purposes of this prospectus supplement, a “business day” means any day, other than a Saturday or Sunday, that is not a day on which banking institutions in the Borough of Manhattan, The City of New York, London or Tokyo are authorized or required by law, regulation or executive order to close and that is a day on which the Trans-European Automated Real-time Gross Settlement Express Transfer System (the TARGET system), or any successor or replacement for that system, operates.

Any amounts payable on any notes that are not punctually paid on any payment date will cease to be payable to the person in whose name such notes are registered on the relevant record date, and such defaulted payment will instead be payable to the person in whose name such notes are registered on the special record date or other specified date determined in accordance with the indenture.

We may redeem some or all of any series of notes after the applicable par call date for such series plus accrued interest to the redemption date as described under “—Optional Redemption.” In addition, we may redeem each series of notes in whole but not in part at any time, if certain events occur involving changes in United States taxation, at the redemption price described under “—Redemption for Tax Reasons.”

Ranking

The notes will be our senior unsecured obligations and will rank pari passu in right of payment with all of our unsubordinated, unsecured indebtedness and will be senior in right of payment to all of our subordinated indebtedness. As of December 31, 2025, we had no secured indebtedness and $22.7 billion of indebtedness, and our subsidiaries had $106.4 billion of indebtedness.

Issuance in Yen; Payment on the Notes

Initial holders will be required to pay for the notes in yen, and all payments of principal of, the redemption price (if any), and interest and additional amounts (as defined below, if any), on the notes, will be payable in yen, provided, that if on or after the date of this prospectus supplement, the yen is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control, then all payments in respect of the notes will be made in U.S. dollars until the yen is again available to us or so used. The amount payable on any date in yen 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/yen exchange rate published in The Wall Street Journal on or prior to the second business day prior to the relevant payment date or, in the event the Wall Street Journal has not published such exchange rate, the rate will be determined in our sole discretion on the basis of the most recently available market exchange rate for the yen. Any payment in

S-12

respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes. Neither the trustee nor the paying agent shall have any responsibility for any calculation or conversion in connection with the foregoing.

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

The Trustee, Paying Agent and Registrar

The Bank of New York Mellon Trust Company, N.A. is the trustee with respect to the notes at its corporate office located at 311 S. Wacker Drive, Suite 6200B, Floor 62, Mailbox #44, Chicago, IL 60606, United States of America. The Bank of New York Mellon Trust Company, N.A. currently serves as the trustee with respect to certain of our other outstanding debt securities.

The trustee is not required to exercise any of its rights or powers under the indenture at the request or direction of any holders unless such holders offer the trustee security or indemnity reasonably satisfactory to the trustee against the costs, expenses and liabilities that might be incurred by the trustee in compliance with such request or direction. Subject to such right of security or indemnity and to certain other limitations, the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of the relevant series may 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, with respect to the securities of such series.

The Bank of New York Mellon, London Branch, will initially act as paying agent for the notes at its corporate office located at 160 Queen Victoria Street, London EC4V 4LA, United Kingdom. The Bank of New York Mellon Trust Company, N.A., will initially act as security registrar for the notes. Upon notice to the trustee, we may change any paying agent or security registrar.

Optional Redemption

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of the series of notes to be redeemed. Any notice of redemption may, at our discretion, be subject to one or more conditions precedent, including, but not limited to, completion of securities offerings or other corporate transactions. We will give the notice in the manner described under “—Notices.”

In the case of a partial redemption, selection of the notes of the applicable series for redemption will be made by lot. 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 through Clearstream/Euroclear (or another depositary), the redemption of the notes will be done in accordance with the policies and procedures of the depositary.

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.

S-13

Payment of Additional Amounts

All payments of principal and interest in respect of the notes will be made free and clear of, and without deduction or withholding for or on account of any present or future taxes, duties, assessments or other governmental charges of whatsoever nature required to be deducted or withheld by the United States or any political subdivision or taxing authority of or in the United States, unless such withholding or deduction is required by law or the official interpretation or administration thereof.

In the event any withholding or deduction on payments in respect of the notes for or on account of any present or future tax, assessment or other governmental charge is required to be deducted or withheld by the United States or any political subdivision or taxing authority thereof or therein, we will pay such additional amounts on the notes as will result in receipt by each beneficial owner of a note that is not a U.S. Person (as defined below) of such amounts (after all such withholding or deduction, including on any additional amounts) as would have been received by such beneficial owner had no such withholding or deduction been required. We will not be required, however, to make any payment of additional amounts for or on account of:

(a)

any tax, assessment or other governmental charge that would not have been imposed but for (1) the existence of any present or former connection (other than a connection arising solely from the ownership of those notes or the receipt of payments in respect of those notes) between a holder of a note (or the beneficial owner for whose benefit such holder holds such note), or between a fiduciary, settlor, beneficiary of, member or shareholder of, or possessor of a power over, that holder or beneficial owner (if that holder or beneficial owner is an estate, trust, partnership or corporation) and the United States, including that holder or beneficial owner, or that fiduciary, settlor, beneficiary, member, shareholder or possessor, being or having been a citizen or resident or treated as a resident of the United States or being or having been engaged in trade or business or present in the United States or having had a permanent establishment in the United States or (2) the presentation of a note for payment on a date more than 30 days after the later of the date on which that payment becomes due and payable and the date on which payment is duly provided for;

(b)	any estate, inheritance, gift, sales, transfer, capital gains, excise, personal property, wealth or similar tax, assessment or other governmental charge;

(c)

any tax, assessment or other governmental charge imposed by reason of the beneficial owner’s past or present status as a passive foreign investment company, a controlled foreign corporation, a foreign tax exempt organization or a personal holding company with respect to the United States or as a corporation that accumulates earnings to avoid U.S. federal income tax;

(d)	any tax, assessment or other governmental charge which is payable by any method other than withholding or deducting from payment of principal of or premium, if any, or interest on such notes;

(e)	any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal of and premium, if any, or interest on any note if that payment can be made without withholding by any other paying agent;

(f)

any tax, assessment or other governmental charge which would not have been imposed but for the failure of a beneficial owner or any holder of notes to comply with our request or a request of our agent to satisfy certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with the United States of the beneficial owner or any holder of the notes that such beneficial owner or holder is legally able to deliver (including, but not limited to, the requirement to provide an applicable Internal Revenue Service Form W-8, or any subsequent versions thereof or successor thereto, and including, without limitation, any documentation requirement under an applicable income tax treaty);

(g)

any tax, assessment or other governmental charge imposed on interest received by (1) a 10-percent shareholder (as defined in Section 871(h)(3)(B) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the U.S. Treasury regulations that may be promulgated thereunder) of ours, (2) a controlled foreign corporation that is related to us within the meaning of Section 864(d)(4) of the Code or (3) a bank

S-14

receiving interest described in Section 881(c)(3)(A) of the Code, to the extent such tax, assessment or other governmental charge would not have been imposed but for the beneficial owner’s status as described in clauses (1) through (3) of this paragraph (g);

(h)

any tax, assessment or other governmental charge required to be withheld or deducted under Sections 1471 through 1474 of the Code (or any amended or successor version of such Sections) (“FATCA”), any regulations or other guidance thereunder, or any agreement (including any intergovernmental agreement) entered into in connection therewith; or any law, regulation or other official guidance enacted in any jurisdiction implementing FATCA or an intergovernmental agreement in respect of FATCA; or

(i)	any combination of items (a), (b), (c), (d), (e), (f), (g) and (h);

nor will we pay any additional amounts to any beneficial owner or holder of notes who is a fiduciary or partnership (including any entity treated as a partnership for U.S. federal income tax purposes) to the extent that a beneficiary or settlor with respect to that fiduciary or a member of that partnership or a beneficial owner thereof would not have been entitled to the payment of those additional amounts had that beneficiary, settlor, member or beneficial owner been the beneficial owner of those notes.

As used in the preceding paragraph, “U.S. Person” means any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, a corporation, partnership or other entity created or organized in or under the laws of the United States, any state of the United States or the District of Columbia (other than a partnership that is not treated as a United States person under any applicable U.S. Treasury regulations), or any estate or trust the income of which is subject to United States federal income taxation regardless of its source.

Any reference in the terms of the notes to any amounts in respect of the notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

Redemption for Tax Reasons

If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any political subdivision of or taxing authority in the United States), or any change in, or amendment to, an official position regarding the application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction in the United States), which change or amendment 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, there is a substantial probability that we will become, obligated to pay additional amounts as described under the heading “—Payment of Additional Amounts” with respect to the notes of a series, then we may at any time at our option redeem such series of notes, in whole but not in part, on not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of their principal amount, together with accrued and unpaid interest on the notes to, but excluding, the date fixed for redemption.

Book-Entry Delivery and Form

General

The notes offered hereby will be issued in registered, global form in minimum denominations of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof. The notes will be issued on the issue date therefor only against payment in immediately available funds. Each series of notes will be issued in the form of one or more global certificates in definitive, fully registered form without interest coupons, each of which we refer to as a “global note.” Each such global note will be deposited with the common depositary and registered in the name of the common depositary or its nominee. We will not issue certificated securities to you for the notes you purchase, except in the limited circumstances described below.

Beneficial interests in the global notes will be represented, and transfers of such beneficial interest will be effected, through accounts of financial institutions acting on behalf of beneficial owners as direct or indirect

S-15

participants in Clearstream or Euroclear. Investors may hold beneficial interests in notes directly through Clearstream or Euroclear, if they are participants in such systems, or indirectly through organizations that are participants in such systems. The address of Clearstream is 42 Avenue JF Kennedy, L-1855 Luxembourg, Luxembourg, and the address of Euroclear is 1 Boulevard Roi Albert II, B-1210 Brussels, Belgium. 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.

Beneficial interests in the global notes will be shown on, and transfers of beneficial interests in the global notes will be made only through, records maintained by Clearstream or Euroclear and their participants. When you purchase notes through the Clearstream or Euroclear systems, the purchases must be made by or through a direct or indirect participant in the Clearstream or Euroclear system, as the case may be. The participant will receive credit for the notes that you purchase on Clearstream’s or Euroclear’s records, and, upon its receipt of such credit, you will become the beneficial owner of those notes. Your ownership interest will be recorded only on the records of the direct or indirect participant in Clearstream or Euroclear, as the case may be, through which you purchase the notes and not on Clearstream’s or Euroclear’s records. Neither Clearstream nor Euroclear, as the case may be, will have any knowledge of your beneficial ownership of the notes. Clearstream’s or Euroclear’s records will show only the identity of the direct participants and the amount of the notes held by or through those direct participants. You will not receive a written confirmation of your purchase or sale or any periodic account statement directly from Clearstream or Euroclear. You should instead receive those documents from the direct or indirect participant in Clearstream or Euroclear through which you purchase the notes. As a result, the direct or indirect participants are responsible for keeping accurate account of the holdings of their customers. The paying agent will wire payments on the notes to the common depositary as the holder of the global notes. The trustee, the paying agent and we will treat the common depositary or any successor nominee to the common depositary as the owner of the global notes for all purposes. Accordingly, the trustee, the paying agent and we will have no direct responsibility or liability to pay amounts due with respect to the global notes to you or any other beneficial owners in the global notes. Any redemption or other notices with respect to the notes will be sent by us directly to Clearstream or Euroclear, which will, in turn, inform the direct participants (or the indirect participants), which will then contact you as a beneficial holder, all in accordance with the rules of Clearstream or Euroclear, as the case may be, and the internal procedures of the direct participant (or the indirect participant) through which you hold your beneficial interest in the notes. Clearstream or Euroclear will credit payments to the cash accounts of Clearstream customers or Euroclear participants in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. Clearstream and Euroclear have established their 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 or change those procedures at any time.

Initial Settlement

Investors will follow the settlement procedures applicable to conventional eurobonds in registered form. It is intended that notes will be credited to the securities custody accounts of Clearstream and Euroclear holders on the settlement date on a delivery against payment basis. None of the notes may be held through, no trades of the notes will be settled through, and no payments with respect to the notes will be made through, The Depository Trust Company in the United States.

Secondary Market Trading

Any secondary market trading of book-entry interests in the notes will take place through participants in Clearstream and Euroclear in accordance with the normal rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in registered form.

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.

S-16

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.

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 or Japan. 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 Luxembourg or Brussels, depending on whether Clearstream or Euroclear is used.

Clearstream and Euroclear

We have obtained the information in this section concerning Clearstream and Euroclear, and the book-entry system and procedures, from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information.

Clearstream has advised us that it is a limited liability company organized under Luxembourg law. Clearstream holds securities for its participating organizations and facilitates the clearance and settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream participants, 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. Clearstream is registered as a bank in Luxembourg, and as such is subject to regulation by the Luxembourg Commission de Surveillance du Secteur Financier. Clearstream participants 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. Indirect access to Clearstream is available to other institutions that clear through or maintain a custodial relationship with a Clearstream participant.

Euroclear advises 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 S.A./N.V. (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, 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 is regulated and examined by the Belgian Banking and Finance Commission. 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. These 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

S-17

behalf of Euroclear participants, and has no record of or relationship with persons holding securities through Euroclear participants.

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.

Certificated Notes

The global notes for a series are exchangeable for certificated notes of the same series in definitive, fully registered form without interest coupons in minimum denominations of ¥100,000,000 principal amount and integral multiples of ¥10,000,000 in excess thereof only in the following limited circumstances:

•

the depositary for any of the notes of such series notifies us that it is unwilling or unable to continue as depositary for the global notes of such series,

•

if there shall have occurred and be continuing an event of default with respect to the notes of such series, or

•

if we determine, in our sole discretion, that the global notes of such series are exchangeable in accordance with the terms of the indenture.

In all cases, certificated notes delivered in exchange for any global note or beneficial interests therein will be registered in the names, and issued in any approved denominations, as the depositary shall direct. Subject to the foregoing, a global note is not exchangeable, except for a global note of the same aggregate denomination to be registered in the name of the common depositary or its nominee.

Notices

Except as otherwise described herein, notice to registered holders of the notes will be given by mail to the addresses as they appear in the security register. Notices will be deemed to have been given on the date of such mailing. So long as the notes are represented by a global note deposited with The Bank of New York Mellon, London Branch, or any successor thereto, as the common depositary for Clearstream and Euroclear, notices to holders may be given by delivery to Clearstream and Euroclear, and such notices shall be deemed to be given on the date of delivery to Clearstream and Euroclear. The trustee will transmit notices to each registered holder’s last known address as it appears in the security register that the trustee maintains. The trustee will only transmit these notices to the registered holder of the notes. You will not receive notices regarding the notes directly from us unless we reissue the notes to you in fully certificated form.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations that may be relevant to initial holders of the notes. The summary is limited to holders that purchase notes in the initial offering for cash at their initial offering price and that hold the notes as capital assets within the meaning of Section 1221 of the Code, which generally means as property held for investment. The summary does not purport to address all of the tax considerations that may be relevant to a particular holder or to deal with the tax considerations that may be relevant to holders in special tax situations, such as banks, thrifts, real estate investment trusts, regulated investment companies, partnerships and other pass-through entities, insurance companies, dealers in securities or currencies, traders in securities electing to use a mark-to-market method of accounting, accrual basis taxpayers subject to special tax accounting rules under Section 451(b) of the Code, foreign persons (except to the extent specifically provided below), tax-exempt organizations, United States expatriates and certain former citizens or long-term residents of the United States, persons holding notes as part of a straddle, hedge, conversion transaction, “synthetic security” or other integrated investment, persons deemed to sell the notes under the constructive sale provisions of the Code, or U.S. holders (as defined below) whose “functional currency” is not the U.S. dollar, nor does it address federal estate, gift or alternative minimum taxes or state, local, or foreign taxes.

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) or pass-through entity holds notes, the tax treatment of a partner or a member in that partnership or pass-through entity generally will depend upon the status of the partner or the member and upon the activities of the partnership or pass-through entity. A partnership or pass-through entity considering a purchase of the notes, and partners or members in such a partnership or pass-through entity, should consult their own tax advisors regarding the tax consequences to them of the purchase, ownership and disposition of the notes.

This summary is based upon the Code, Treasury regulations, Internal Revenue Service (“IRS”) rulings and pronouncements and administrative and judicial decisions currently in effect, all of which are subject to change (possibly with retroactive effect) or possible differing interpretations. No ruling has been or will be sought from the IRS with respect to the U.S. federal income tax consequences of the purchase, ownership and disposition of the notes. As a result, the IRS could disagree with portions of this discussion.

This discussion is for general purposes only. Persons considering a purchase of the notes should consult their own tax advisors with respect to the tax consequences to them of the purchase, ownership and disposition of the notes in light of their own particular circumstances, including the tax consequences under federal, state, local and foreign tax laws and tax treaties and the possible effects of any changes in applicable tax laws.

Consequences to U.S. Holders

The following discussion summarizes certain U.S. federal income tax considerations relevant to a U.S. holder. For purposes of this discussion, the term “U.S. holder” means a beneficial owner of the notes that is (1) an individual who is a citizen or resident of the United States, (2) a corporation or other entity treated as a corporation for U.S. federal income tax purposes, in each case, that is created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (3) a trust if it (i) is subject to the primary supervision of a U.S. court and the control of one or more United States persons (as defined in the Code) or (ii) has a valid election in effect under applicable Treasury regulations to be treated as a United States person (as defined in the Code), or (4) an estate, the income of which is subject to U.S. federal income tax regardless of its source.

Payments or Accruals of Interest

Payments or accruals of interest on a note will be taxable to U.S. holders as U.S.-source ordinary interest income at the time such U.S. holders receive or accrue such amounts (in accordance with a holder’s regular method of tax accounting).

S-19

A U.S. holder that uses the cash method of accounting and that receives a payment of interest in yen will be required to include in income the U.S. dollar value of the yen payment received (determined based on the spot rate on the date the payment is received), regardless of whether the payment is in fact converted to U.S. dollars at that time. A cash basis U.S. holder will not recognize exchange gain or loss on the receipt of interest income, but may recognize exchange gain or loss attributable to the actual disposition of the yen received as described below.

A U.S. holder that uses the accrual method of accounting will accrue interest income in yen and translate that amount into U.S. dollars based on the average spot rate of exchange in effect for the accrual period or, with respect to an accrual period that spans two taxable years, at the average spot rate for the partial period within the applicable taxable year. Alternatively, an accrual method U.S. holder may elect to translate interest income into U.S. dollars at the spot rate on the last day of the accrual period (or the last day of the taxable year in the case of an accrual period that spans two taxable years) or, if the date of receipt is within five business days of the last day of the interest accrual period, the spot rate on the date of receipt. A U.S. holder that makes this election must apply it consistently to all debt instruments from year to year and cannot change the election without the consent of the IRS. A U.S. holder that uses the accrual method will recognize exchange gain or loss with respect to accrued interest income on the date the interest payment is actually received. The amount of exchange gain or loss recognized will equal the difference, if any, between the U.S. dollar value of the yen payment received (determined based on the spot rate on the date the payment is received) in respect of the accrual period and the U.S. dollar value of interest income that has accrued during the accrual period (as determined above), regardless of whether the payment is in fact converted to U.S. dollars. This exchange gain or loss generally will be treated as U.S.-source ordinary income or loss.

Sale, Exchange, Redemption or Other Disposition of the Notes

When a U.S. holder disposes of a note by sale, exchange, redemption or other disposition, the holder will generally recognize gain or loss equal to the difference between the amount the holder realizes on the transaction (less any amount attributable to accrued and unpaid interest, which will be taxable as such) and the holder’s adjusted tax basis in the note. A U.S. holder’s adjusted tax basis in a note will generally equal the U.S. dollar value of the yen used to purchase the note using the spot exchange rate on the purchase date. If a note is traded on an established securities market, as the notes are expected to be, a cash basis U.S. holder (and if it elects, an accrual basis U.S. holder) will determine the U.S. dollar value of the yen amount paid for the note on the settlement date of the purchase. Payments received that are attributable to accrued interest will be treated in accordance with the rules applicable to payments of interest, described above.

The amount realized on the sale, exchange, redemption or other disposition of a note for an amount in yen will generally be the U.S. dollar value of such yen based on the spot exchange rate on the date the note is disposed of; provided, however, that if the note is traded on an established securities market, as the notes are expected to be, a cash basis U.S. holder (and if it elects, an accrual basis U.S. holder) will determine the U.S. dollar value of such yen on the settlement date of the disposition.

If an accrual method U.S. holder makes either of the settlement date elections described above, such election must be applied consistently to all debt instruments from year to year and cannot be changed without the consent of the IRS. If a note is not traded on an established securities market (or, if a note is so traded, but a U.S. holder is an accrual basis U.S. holder that has not made the settlement date election), a U.S. holder will recognize exchange gain or loss (taxable as U.S.-source ordinary income or loss) to the extent that the U.S. dollar value of the yen received (based on the spot rate on the settlement date), differs from the U.S. dollar value of the amount realized.

Except as discussed below with respect to exchange gain or loss, the gain or loss that a U.S. holder recognizes on the sale, exchange, redemption or other disposition of a note will generally be U.S.-source capital gain or loss and will be long-term capital gain or loss if the holder held the note for more than one year on the date of disposition. Long-term capital gains recognized by non-corporate U.S. holders (including individuals) are subject to taxation at preferential rates. The tax deductibility of capital losses is subject to limitations.

S-20

Any gain or loss realized upon the sale, exchange, redemption or other disposition of a note that is attributable to fluctuations in currency exchange rates will be exchange gain or loss. Gain or loss attributable to fluctuations in currency exchange rates generally will equal the difference between (i) the U.S. dollar value of a U.S. holder’s purchase price for the note in yen determined on the date the note is disposed of, and (ii) the U.S. dollar value of a U.S. holder’s purchase price for the note in yen determined on the date the U.S. holder acquired the note (or, in each case, determined on the settlement date if the notes are traded on an established securities market, as the notes are expected to be, and the U.S. holder is either a cash basis or an electing accrual basis holder). The exchange gain or loss (with respect to both principal and accrued interest) will be recognized only to the extent of the total gain or loss realized by a U.S. holder on the sale, exchange, redemption or other disposition of the note, and generally will be U.S.-source ordinary income or loss.

Exchange of Yen

A U.S. holder’s tax basis in the yen received as interest on, or on the sale or other disposition of, a note will be the U.S. dollar value of such yen at the spot rate in effect on the date of receipt of the yen. Any gain or loss recognized by a U.S. holder on a sale, exchange or other disposition of the yen will be U.S.-source ordinary income or loss.

Tax Return Disclosure Requirements

Certain U.S. Treasury regulations meant to require the reporting of certain tax shelter transactions cover transactions generally not regarded as tax shelters, including certain foreign currency transactions giving rise to losses in excess of a certain minimum amount (e.g., $50,000 in a single transaction in the case of an individual or trust, and higher amounts for non-individual, non-trust taxpayers), such as the receipt of interest on a foreign currency note or a sale, exchange, retirement or other taxable disposition of a foreign currency note or of foreign currency received in respect of a foreign currency note. Persons considering the purchase of notes should consult with their own tax advisors to determine the U.S. federal income tax return disclosure obligations, if any, with respect to an investment in the notes or the disposition of yen, including any requirement to file IRS Form 8886 (Reportable Transaction Disclosure Statement).

3.8% Medicare Tax On “Net Investment Income”

U.S. holders that are individuals, estates, and certain trusts are subject to an additional 3.8% Medicare tax on the lesser of (a) such holder’s “net investment income” (or undistributed “net investment income” in the case of an estate or trust) for the relevant taxable year and (b) the excess of the U.S. holder’s modified gross income for the taxable year over certain thresholds (generally $200,000 for an unmarried individual, $250,000 for a married taxpayer filing a joint return (or a surviving spouse), or $125,000 for a married individual filing a separate return). Net investment income will generally include interest income and net gains from the disposition of the notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). U.S. holders should consult their advisors with respect to their consequences with respect to the 3.8% Medicare tax.

Backup Withholding and Information Reporting

Unless a U.S. holder is an exempt recipient, payments under the notes or proceeds received from the sale of the notes will generally be subject to information reporting and will generally also be subject to U.S. federal backup withholding tax if such U.S. holder fails to supply an accurate taxpayer identification number or otherwise fails to comply with applicable U.S. information reporting or certification requirements. Any amounts so withheld do not constitute a separate tax and will generally be allowed as a refund or a credit against the U.S. holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

S-21

Consequences to Non-U.S. Holders

The following discussion summarizes certain U.S. federal income tax considerations relevant to a non-U.S. holder. For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of the notes that for U.S. federal income tax purposes is a nonresident alien individual, a foreign corporation, or a trust or estate that is not a U.S. holder.

Payments of Interest

Subject to the discussions below under “—Backup Withholding and Information Reporting” and “—Foreign Account Tax Compliance Act”, payments of interest on the notes made to a non-U.S. holder will generally be exempt from U.S. federal income and withholding tax, provided that:

•

the non-U.S. holder does not own, actually or constructively, 10 percent or more of the total combined voting power of all classes of our stock entitled to vote, and is not a controlled foreign corporation related, directly or through attribution, to us through stock ownership;

•

the non-U.S. holder is not a bank receiving interest on a loan entered into in the ordinary course of its trade or business;

•

either (i) the non-U.S. holder certifies on IRS Form W-8BEN or Form W-8BEN-E (or a successor form), under penalties of perjury, that it is a non-U.S. holder and provides its name and address or otherwise satisfies applicable documentation requirements or (ii) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the notes on behalf of the non-U.S. holder certifies under penalties of perjury that the certification referred to in clause (i) has been received from the non-U.S. holder or an intermediate financial institution and furnishes a copy thereof; and

•

the payments are not effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States.

If a non-U.S. holder cannot satisfy the requirements described above, payments of interest made to such non-U.S. holder will be subject to a 30% U.S. federal withholding tax, unless such non-U.S. holder provides the applicable withholding agent with a properly executed:

•

IRS Form W-8BEN or Form W-8BEN-E (or a successor form) claiming an exemption from or reduction in withholding under the benefit of an applicable tax treaty; or

•

IRS Form W-8ECI (or a successor form) stating that interest paid on the notes is not subject to withholding tax because it is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States.

If payments of interest on the notes are effectively connected with the conduct by a non-U.S. holder of a trade or business in the United States (and, where an income tax treaty applies, are attributable to a United States permanent establishment), then such non-U.S. holder will be subject to U.S. federal income tax on such interest payments on a net income basis in the same manner as a U.S. holder (but without regard to the 3.8% Medicare tax, described above), although such non-U.S. holder will be exempt from the 30% U.S. federal withholding tax if the certification requirements discussed above are satisfied. In addition, a non-U.S holder that is a foreign corporation may be subject to an additional branch profits tax equal to 30% (or lower applicable tax treaty rate) of such interest, subject to adjustments.

Sale, Exchange, Redemption or Other Disposition of the Notes

Subject to the discussions below under “—Backup Withholding and Information Reporting” and “—Foreign Account Tax Compliance Act”, any gain realized by a non-U.S. holder upon a sale, exchange, redemption or other disposition of the notes will generally not be subject to U.S. federal income tax, unless:

•

the gain is effectively connected with the conduct of a trade or business in the United States by the non- U.S. holder (and, where an income tax treaty applies, is attributable to a United States permanent establishment); or

S-22

•

the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met.

Any gain realized by a non-U.S. holder upon a sale, exchange, redemption or other disposition of the notes that is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States (and, where an income tax treaty applies, is attributable to a United States permanent establishment) will generally be taxable as discussed above with respect to effectively connected interest on the notes. If a non-U.S. holder is subject to U.S. federal income tax because the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition, any gain realized by the non-U.S. holder on the sale, exchange, redemption or other disposition of the notes that is not effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States will be subject to a flat 30% tax on the gain derived from such disposition (or lower applicable tax treaty rate), which gain may be offset by U.S.-source capital losses.

Backup Withholding and Information Reporting

Generally, information reporting will apply to the amount of interest paid to each non-U.S. holder and the amount of tax, if any, withheld with respect to those payments. These reporting requirements apply regardless of whether withholding is reduced or eliminated by the Code or an applicable income tax treaty or otherwise. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which a non-U.S. holder resides under the provisions of an applicable tax treaty or agreement.

In general, a non-U.S. holder will not be subject to U.S. federal backup withholding with respect to payments of interest on the notes if the non-U.S. holder provides an IRS Form W-8BEN or Form W-8BEN-E (or a successor form) with respect to such payments or otherwise satisfies applicable documentation requirements. In addition, no information reporting or backup withholding will generally be required with respect to the proceeds of a sale or other disposition of the notes by a non-U.S. holder made within the United States or conducted through certain United States-related financial intermediaries if the payor receives such a form or the non-U.S. holder otherwise establishes an exemption.

Backup withholding is not an additional tax and any amounts so withheld will generally be allowed as a refund or a credit against the non-U.S. holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

Withholding taxes may be imposed under FATCA on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on payments of interest on, or (subject to the proposed Treasury regulations discussed below) gross proceeds from the sale or other disposition of, a note paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

S-23

Withholding under FATCA generally will apply to payments of interest on a note regardless of when they are made. Under the applicable final Treasury regulations, withholding under FATCA generally applies to payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019. However, pursuant to proposed Treasury regulations (upon which taxpayers may generally rely until applicable final regulations are issued or such proposed Treasury regulations are rescinded), gross proceeds from the sale or other disposition of a note will not be subject to withholding under FATCA. Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in the notes.

S-24

UNDERWRITING (Conflicts of Interest)

We have entered into an underwriting agreement with Mizuho Securities USA LLC and Merrill Lynch International with respect to the notes. Subject to certain conditions, we have agreed to sell to each underwriter and each underwriter named below has severally agreed to purchase from us the principal amount of the notes that appears opposite its name in the table below.

Principal amount
of % Senior
Notes due

Mizuho Securities USA LLC

The underwriters have agreed to purchase all of the notes if any of them are purchased. The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to, among other customary conditions, the delivery of certain legal opinions by their counsel. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to (i) % of the principal amount of the % Senior Notes due ; (ii) % of the principal amount of the % Senior Notes due ; and (iii) % of the principal amount of the % Senior Notes due . In addition, the underwriters may allow, and those selected dealers may reallow, a concession of up to (i) % of the principal amount of the % Senior Notes due; (ii) % of the principal amount of the % Senior Notes due ; and (iii) % of the principal amount of the % Senior Notes due to certain other dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates. The 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.

In the underwriting agreement, we have agreed that, subject to certain exceptions, we will indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

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


	Underwriting Discount paid by us
	Per Note		Total
% Senior Notes due		%	¥
% Senior Notes due		%	¥
% Senior Notes due		%	¥

We estimate that we will spend approximately $ for printing, rating agency fees, trustee and legal fees and other expenses related to this offering.

The notes are new issues of securities with no established trading market. We do not intend to apply for any series of the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system.

S-25

The underwriters have advised us that they intend to make a market in the notes. However, they are not obligated to do so and may discontinue any market making at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

In connection with the issue of the notes, Mizuho Securities USA LLC (in this capacity, the “Stabilizing Manager”) (or persons acting on behalf of the Stabilizing Manager) may over-allot notes or effect transactions with a view to supporting the market price of the notes at a level higher than that which might otherwise prevail. However, there is no assurance that the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) will undertake any stabilization action. Any stabilization action may begin on or after the date on which adequate public disclosure of the final 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 of the notes and 60 days after the date of the allotment of the notes. Such stabilization shall be carried out in accordance with applicable laws and regulations. Any loss or profit sustained as a consequence of any such over-allotment or stabilization shall be for the account of the Stabilizing Manager. The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the Stabilizing Manager has repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions. The address of the Stabilizing Manager is 1271 Avenue of the Americas, New York, NY 10020.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. The underwriters are not required to engage in these activities, but if these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

Each underwriter and its 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. Each underwriter and certain of its affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they have received or will receive customary fees and expenses reimbursements. The underwriters and their affiliates may also make investment recommendations and/ or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

In the ordinary course of their various business activities, the underwriters and their 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 or its affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

We expect that delivery of the notes will be made against payment therefor on or about , 2026, which is the Tokyo business day following the date of this prospectus supplement (such settlement cycle being referred to as “T+ ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the business day before delivery

S-26

hereunder will be required, by virtue of the fact that the notes initially will settle in T+ , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to the business day before their date of delivery hereunder should consult their own advisors.

Conflicts of Interest

Certain of the underwriters and/or their affiliates may own the 2026 Senior Notes and, as a result, may receive a portion of the net proceeds from this offering.

Offering Restrictions

Canada

Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement or the accompanying prospectus (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

Use of Proceeds

Except as any applicable prospectus supplement may indicate otherwise, we intend to use the net proceeds from the sale of debt securities offered by this prospectus for general corporate purposes.

Description of the Debt Securities

We will issue debt securities on a senior unsecured basis under an indenture, dated as of January 31, 2025, by and among Berkshire, Berkshire Hathaway Finance Corporation (“BHFC”) and The Bank of New York Mellon Trust Company, N.A. (the “trustee”). BHFC may also issue debt securities under this indenture; however, the debt securities described in this prospectus are solely issued by Berkshire Hathaway Inc.

We have summarized material provisions of the indenture and the debt securities below. This summary is not complete, and is subject, and qualified in its entirety by reference, to all the provisions of the indenture, including the definition of certain terms. We have filed the indenture with the SEC as an exhibit to the registration statement of which this prospectus forms a part, and you should read the indenture for provisions that may be important to you. The following sets forth certain general terms and provisions of our debt securities offered by this prospectus. The particular terms of any debt securities being offered will be described in the prospectus supplement relating to those offered debt securities.

Provisions Applicable to Indenture

General

The indenture does not limit the amount of debt securities that may be issued under that indenture, nor does it limit the amount of other unsecured debt or securities that we may issue. We may issue debt securities under the indenture from time to time in one or more series, each in an amount authorized prior to issuance.

•

the total principal amount of the debt securities;

the date or dates on which the principal of and any premium on the debt securities will be payable;

•

any interest rate, the date from which interest will accrue, interest payment dates and record dates for interest payments;

any other terms of the debt securities not inconsistent with the indenture.

Ranking

The debt securities will be our senior unsecured obligations and will rank pari passu in right of payment with all of our unsubordinated, unsecured indebtedness and will be senior in right of payment to all of our subordinated indebtedness, and will be effectively subordinated to all of our existing and future secured indebtedness to the extent of the assets securing such indebtedness and structurally subordinated to all existing and future indebtedness of our subsidiaries (secured or unsecured).

Consolidation, Merger and Sale of Assets

Except as otherwise provided in the indenture or the debt securities, we may not merge into or consolidate with any other entity, or convey, transfer or lease our respective properties and assets substantially as an entirety to any individual, corporation, partnership or other entity, unless:

•

the successor or transferee corporation (or other entity) shall (i) be a corporation, partnership, limited liability company, trust or similar entity organized under the laws of the United States of America, any State of the United States or the District of Columbia, and (ii) expressly assume by supplemental indenture the due and punctual payment of the principal of and any interest on the debt securities and the performance of our obligations under the indenture; and

•

immediately after giving effect to the transaction, no event of default, and no event which, after notice of lapse of time or both, would become an event of default will have occurred or be continuing.

Events of Default

Unless we inform you otherwise in the applicable prospectus supplement, the following are events of default with respect to a series of debt securities:

•

a default in the payment of any interest on such series of debt securities when due and payable, and the continuance of such default for a period of 60 days;

•

a default in the payment of principal of such series of debt securities when due and payable;

•

a default in the performance, or breach, in any material respect, of other covenants of ours in the indenture applicable to such series of debt securities that continues for 90 consecutive days after we receive notice of the default or breach; and

•

certain events of bankruptcy, insolvency or liquidation involving us.

If an event of bankruptcy, insolvency or liquidation of us has occurred, the principal of the then-outstanding debt securities and any other amounts payable under the indenture will become immediately due and payable. If any other event of default shall occur and be continuing, either the trustee or the holders of not less than 33% in aggregate principal amount of the outstanding debt securities of all series (or, if such default is not applicable to all series of the debt securities, the holders of at least 33% in aggregate principal amount of the outstanding debt securities of all series to which such default is applicable) (in each case, voting as a single class) may declare the principal amount payable under the indenture on those then outstanding debt securities of the series affected by the default due and payable.

Defeasance

Our obligations with respect to the payment of the principal and interest on the debt securities will terminate if we irrevocably deposit or cause to be deposited with the trustee as trust funds specifically held in trust for, and dedicated solely to, the benefit of the holders of the debt securities:

•

cash,

•

U.S. government obligations, which through the scheduled payment of interest and principal in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, cash, or

•

a combination of the foregoing,

in each case sufficient to pay and discharge each installment of principal and interest on the debt securities.

The discharge of the debt securities is subject to certain other conditions, including, without limitation,

•

no event of default or event (including such deposit) which with notice or lapse of time would become an event of default shall have occurred and be continuing on the date of such deposit (or, with respect to an event of bankruptcy, insolvency or liquidation of us, at any time on or prior to the 90th day after the date of such deposit),

•

we shall have delivered to the trustee an opinion of tax counsel to the effect that beneficial owners of the debt securities will not recognize gain or loss for United States federal income tax purposes as a result of such deposit and defeasance,

•

the debt securities, if they are then listed on any securities exchange, will not be delisted as a result of such deposit, and

•

such deposit shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which we are a party or otherwise bound.

Modification and Waiver

Modification of Indenture

The indenture provides that we and the trustee may, without the consent of any holders of debt securities, enter into supplemental indentures for the purposes, among other things, of adding to our covenants, adding additional events of default and curing ambiguities or inconsistencies in the indenture. We and the trustee may, without the consent of any holders of debt securities, also make other changes to the indenture that do not have a material adverse effect on the interests of the holders of any series of debt securities.

In addition, modifications and amendments of the indenture may be made by us and the trustee by entering into a supplemental indenture with the consent of the holders of not less than a majority of the aggregate principal amount of the debt securities of each series affected by such modification or amendment, acting as one class, provided, however, that no such modification or amendment may, without the consent of each holder of debt securities outstanding that is affected thereby,

•

change the stated maturity of the principal of, or any installment of principal of or interest on, any outstanding debt securities,

•

reduce the principal of or interest rate on any outstanding debt securities,

•

change the place of payment where, or the currency in which, the principal of, any premium or interest on any outstanding debt securities is payable,

•

impair the right to institute suit for the enforcement of any payment on or with respect to any outstanding debt securities on or after the stated maturity thereof,

•

reduce the percentage in principal amount of the debt securities then outstanding required for modification or amendment of the indenture or for any waiver of compliance with certain provisions of the indenture or for waiver of certain defaults, or

•

modify any of the above provisions.

Waiver of Default

The holders of not less than a majority of aggregate principal amount of the outstanding debt securities of any series may, on behalf of the holders of all such series of debt securities, waive any past default under the indenture with respect to such series of debt securities, except a default:

•

in the payment of principal of or any premium or any interest on such debt securities, or

•

in respect of a covenant or provision of the indenture that cannot be modified or amended without the consent of each holder of the outstanding debt securities of each series affected by the default.

Payment and Paying Agents

Unless we inform you otherwise, payments on the debt securities will be made in U.S. dollars at the office or agency maintained by us in New York, New York (or, if we fail to maintain such office or agency, at the corporate trust office of the trustee in New York, New York or if the trustee does not maintain an office in New York, at the office of a paying agent in New York). At our option, however, we may make payments by check mailed to the holder’s registered address or, with respect to global notes, by wire transfer. We will make any required interest payments to the person in whose name a debt security is registered at the close of business on the record date for the interest payment.

Unless we inform you otherwise, the trustee will be designated as our paying agent for payments on the debt securities. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts.

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent shall pay to us upon written request any money held by them for payments on the debt securities that remain unclaimed for one year after the date upon which that payment has become due. After payment to us, holders entitled to the money must look to us for payment. In that case, all liability of the trustee or paying agent with respect to that money will cease.

Notices

Except as otherwise described herein, notice to registered holders of the debt securities will be given by mail to the addresses as they appear in the security register. Notices will be deemed to have been given on the date of such mailing, and to have been received by such registered holders whether or not actually received by such registered holders.

Governing Law

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

Plan of Distribution

•

directly to purchasers or a single purchaser;

•

through agents;

If the debt securities described in a prospectus supplement are underwritten, the prospectus supplement will name each underwriter of the debt securities. Only underwriters named in a prospectus supplement will be deemed to be underwriters of the debt securities offered by that prospectus supplement. Underwriters may sell debt securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions (which may be changed from time to time) from the purchasers for whom they may act as agent.

Unless otherwise indicated in the prospectus supplement, any agent involved in the offer or sale of securities will be acting on a best efforts basis for the period of its appointment.

If we utilize a dealer in the sale of the debt securities being offered pursuant to this prospectus, we will sell the debt securities to the dealer, as principal. The dealer may then resell the debt securities to the public at varying prices to be determined by the dealer at the time of resale.

If indicated in a prospectus supplement, the obligations of the underwriters will be subject to conditions precedent. With respect to a sale of securities, the underwriters will be obligated to purchase all securities offered if any are purchased.

We may have agreements with underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act, and to reimburse them for certain expenses.
