Caterpillar Inc.

Overview

With 2024 sales and revenues of $64.809 billion, Caterpillar is the world’s leading manufacturer of construction and mining equipment, off-highway diesel and natural gas engines, industrial gas turbines and diesel-electric locomotives. The company principally operates through its three primary segments — Construction Industries, Resource Industries and Energy & Transportation — and also provides financing and related services through its Financial Products segment. Caterpillar is also a leading U.S. exporter. Through a global network of independent dealers and direct sales of certain products, Caterpillar builds long-term relationships with customers around the world.

Currently, we have five operating segments, of which four are reportable segments and are described below.

Our Construction Industries segment is primarily responsible for supporting customers using machinery in infrastructure and building construction applications. The majority of machine sales in this segment are made in the heavy and general construction, rental, quarry and aggregates and mining industries.

The Resource Industries segment is primarily responsible for supporting customers using machinery in mining, heavy construction and quarry and aggregates. Caterpillar offers a broad product range and services to deliver comprehensive solutions for our customers. We develop and manufacture high productivity equipment for both surface and underground mining operations around the world, as well as provide hydraulic systems, electronics and software for Caterpillar machines and engines. Our equipment is used to extract and haul copper, iron ore, coal, oil sands, aggregates, gold and other minerals and ores, as well as a variety of heavy construction applications. In addition to equipment, Resource Industries also develops and sells technology products and services to provide customers fleet management systems, equipment management analytics and autonomous machine capabilities.

Our Energy & Transportation segment supports customers in oil and gas, power generation, marine, rail and industrial applications, including Caterpillar machines. The product and services portfolio includes reciprocating engines, generator sets, integrated systems and solutions, turbines and turbine-related services, electrified powertrain and zero-emission power sources and service solutions development, the remanufacturing of Caterpillar engines and components, remanufacturing services for other companies, diesel-electric locomotives and other rail-related products and services as well as product support of on-highway engines.

The business of our Financial Products segment is primarily conducted by Cat Financial, Caterpillar Insurance Holdings Inc. (“Insurance Services”) and their respective subsidiaries and affiliates. Cat Financial is a wholly owned finance subsidiary of Caterpillar Inc., and it provides retail and wholesale financing alternatives to customers and dealers around the world for Caterpillar products and services, as well as financing for power generation facilities that, in most cases, incorporate Caterpillar products. Retail financing is primarily comprised of installment sale contracts and other equipment-related loans, working capital loans, finance leases, operating leases, and revolving charge accounts. Wholesale financing to Caterpillar dealers consists primarily of inventory and rental fleet financing. In addition, Cat Financial purchases short-term wholesale trade receivables from Caterpillar. The various financing plans offered by Cat Financial are designed to support sales of Caterpillar products and services and generate financing income for Cat Financial. A significant portion of our activity is conducted in North America, and we have additional offices and subsidiaries in Latin America, Asia/Pacific, Europe and Africa.

TABLE OF CONTENTS

RISK FACTORS

You should carefully consider the following risk factors and the information under the heading “Risk Factors” in the accompanying prospectus and in our Annual Report on Form 10-K for the year ended December 31, 2024, which is incorporated by reference into this prospectus supplement, as well as the other information included or incorporated by reference into this prospectus supplement and the accompanying prospectus, before making an investment decision. In addition, there may be other risks that a prospective investor should consider that are relevant to its own particular circumstances or generally.

Risks Related to the Notes

The notes are our unsecured obligations and will rank effectively junior to the existing and future liabilities of our subsidiaries.

The notes are our unsecured obligations, will rank equally in right of payment with all of our other senior indebtedness and will be structurally subordinated to the debt and all other obligations, including trade payables, of our subsidiaries. The notes are not secured by any of our assets. As of March 31, 2025, we did not have any secured debt outstanding. Any future claims of secured lenders with respect to assets securing their loans will be prior to any claim of the holders of the notes with respect to the value of those assets.

Our ability to service our debt, including the notes, depends on the results of operations of our subsidiaries and upon the ability of such subsidiaries to provide us with cash, whether in the form of dividends, loans or otherwise, to pay amounts due on our obligations, including the notes. Our subsidiaries are separate and distinct legal entities from Caterpillar Inc., the issuer of the notes, and have no obligation, contingent or otherwise, to make payments on the notes or to make any funds available for that purpose. As a result, the notes are structurally subordinated to all liabilities of our subsidiaries, including, without limitation, all indebtedness and trade payables of our subsidiaries. At March 31, 2025, we had approximately $38.6 billion of indebtedness outstanding on a consolidated basis, approximately $29.9 billion of which is subsidiary indebtedness. Our subsidiary indebtedness is structurally senior to the notes offered hereby.

In particular, 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.

The notes do not restrict our ability to incur additional debt or prohibit us from taking other actions that could negatively impact holders of the notes.

The notes and indenture under which the notes will be issued do not place any limitation on the amount of unsecured debt that may be incurred by us. Our incurrence of additional debt may have important consequences for you as a holder of the notes, including making it more difficult for us to satisfy our obligations with respect to the notes, a loss in the market value of your notes and a risk that the credit rating of the notes is lowered or withdrawn.

The terms of the notes do not require us to achieve or maintain any minimum financial results relating to our financial position or results of operations. Our ability to recapitalize, incur additional debt, secure existing or future debt or take a number of other actions that are not limited by the terms of the indenture and the notes, including repurchasing indebtedness or common shares or preferred shares, if any, or paying dividends, could have the effect of diminishing our ability to make payments on the notes when due. In addition, our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations. Our failure to apply these funds effectively could adversely affect our ability to make payments on the notes when due.

S-5

TABLE OF CONTENTS

Our credit ratings may not reflect all risks of an investment in the notes, and changes in our credit ratings may affect the market value and liquidity of the notes.

The credit ratings assigned to the notes may not reflect the potential impact of all risks related to trading markets, if any, for, or trading value 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. Accordingly, you should consult your own financial and legal advisors as to the risks entailed by an investment in the notes and the suitability of investing in the notes in light of your particular circumstances.

In addition, real or anticipated changes in our credit ratings will generally affect any trading market, if any, for, or trading value of, the notes. There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could affect the market value and liquidity of the notes and increase our borrowing costs.

If active trading markets do not develop for the notes of either series, you may be unable to sell your notes or to sell your notes at a price that you deem sufficient.

The notes of either series are new issues of securities for which there currently are no established trading markets. We do not intend to list the notes of either series on a national securities exchange or arrange for quotation on any automated dealer quotation system. While certain of the underwriters of the notes have advised us that they intend to make a market in each series of notes, such underwriters will not be obligated to do so and may stop their market making at any time. No assurance can be given:

•

that a market for either series of the notes will develop or continue;

•

as to the liquidity of any market that does develop; or

•

as to your ability to sell any notes you may own or the price at which you may be able to sell your notes.

We may redeem your notes at our option, which may adversely affect your return.

We have the right to redeem the notes of either series in whole or from time to time in part at the applicable redemption prices described under the caption “Description of the Notes — Optional Redemption.” We may exercise this redemption right when prevailing interest rates are relatively low. As a result, you generally will not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of either series of the notes.

Payment and Paying Agents

We will maintain in the place of payment for the notes an office or agency where the notes may be presented or surrendered for payment or for registration of transfer or exchange and where holders may serve us with notices and demands in respect of the notes and the indenture.

S-10

TABLE OF CONTENTS

We will give prompt written notice to the trustee of the location, and any change in the location, of such office or agency. If we fail to maintain any required office or agency or fail to furnish the trustee with the address of such office or agency, presentations, surrenders, notices and demands may be made or served at the corporate trust office of the trustee. We have appointed the trustee as our agent to receive all presentations, surrenders, notices and demands with respect to the notes.

Optional Redemption

Prior to (i) with respect to the 20 notes, , 20 ( months prior to the maturity date of such notes) and (ii) with respect to the 20 notes, , 20 ( months prior to the maturity date of such notes) (each such date, a “Par Call Date”), we may redeem the applicable series of notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1)

(a) the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed discounted to the redemption date (assuming, in the case of the 20 notes and the 20 notes, that such notes matured on their applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus basis points, in the case of the 20 notes, and basis points, in the case of the 20 notes, less (b) interest accrued to the date of redemption; and

(2)

100% of the principal amount of such notes to be redeemed;

plus, in either case, accrued and unpaid interest on the applicable notes to the redemption date.

On or after the applicable Par Call Date for the 20 notes and the 20 notes, we may redeem the notes of the applicable series in whole or in part, at any time and 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 thereon to the redemption date.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The trustee shall have no duty to verify such determinations.

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 holders of the notes to be redeemed (with a copy to the trustee), except that notice may be given more than 60 days prior to the date fixed for redemption if the notice is issued in connection with a defeasance, covenant defeasance or satisfaction and discharge. The notice of redemption will specify, among other items, the aggregate principal amount of the notes of the applicable series to be redeemed, the redemption date and the redemption price or the manner of calculating the redemption price (in which case no redemption price need be specified).

Any notice of any redemption of notes may, at our discretion, be given subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence of indebtedness or an acquisition or other strategic transaction involving a change of control in us or another entity). If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and, if applicable, shall state that, in our discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, without the requirement of an additional notice period to the holders, 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.

Any notice of redemption may provide that payment of the redemption price and the performance of our obligations with respect to such redemption may be performed by another person.

In the case of a partial redemption, selection of the notes for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair. No notes of a principal amount of $2,000 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.

S-11

TABLE OF CONTENTS

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 DTC (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the depositary.

Unless we default in the 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 and the only remaining right of the holders of such notes will be to receive payment of the redemption price.

Definitions

“Business Day” means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York and on which commercial banks are open for business in New York, New York.

“Treasury Rate” means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on such Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date and one with a maturity date following such Par Call Date, we shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on such Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Sinking Fund

The notes will not be entitled to any sinking fund or have the benefit of any mandatory redemption provisions. We may acquire notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise.

S-12

TABLE OF CONTENTS

Events of Default

With respect to the notes, “Event of Default” shall have the meaning set forth in the accompanying prospectus under “Description of Debt Securities — Events of Default.”

Book-Entry System; Global Clearance and Settlement Procedures

The notes will be issued in book-entry form and The Depository Trust Company (“DTC”) will act as securities depository for the notes. The notes will be issued as one or more fully-registered global notes registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. Except as described in “Description of Debt Securities — Book-Entry Issuance and Global Securities” in the accompanying prospectus, beneficial owners of the notes will not have notes registered in their names, will not receive physical delivery of notes in certificated form and will not be considered the registered owners or “holders” thereof under the indenture for any purpose.

Beneficial owners of the notes may elect to hold interests in the notes through DTC, Clearstream Banking, société anonyme (“Clearstream”) or Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), if they are participants of such systems, or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on DTC’s books. For more information on book-entry and DTC, please see “Description of Debt Securities — Book-Entry Issuance and Global Securities” in the accompanying prospectus.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the notes made through Euroclear or Clearstream must comply with the rules and procedures of those systems. Those systems could change their rules and procedures at any time. We have no control over those systems or their participants and we take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on the one hand, and other participants in DTC, on the other hand, would also be subject to the rules and procedures of DTC.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through those systems only 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, U.S. investors who hold their interests in the notes through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before the expiration date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream may need to make special arrangements to finance any purchases or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than transactions within one clearing system.

The information in this section and “Description of Debt Securities — Book-Entry Issuance and Global Securities” in the accompanying prospectus concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

Trustee

U.S. Bank has performed and may in the future perform for Caterpillar and its subsidiaries various commercial banking services, for which it has received and will receive customary fees and expenses. U.S. Bank and its subsidiaries also serve as trustee with respect to certain other outstanding debt securities of Caterpillar and its subsidiaries.

TABLE OF CONTENTS

CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of certain material United States federal income tax consequences of the purchase, ownership and disposition of the notes. This summary deals only with notes held as capital assets (within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”)) by persons who purchase the notes for cash pursuant to this offering at their “issue price” (the first price at which a substantial amount of the notes of the applicable series is sold for cash to investors, excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriter, placement agent or wholesaler).

As used herein, a “U.S. holder” means a beneficial owner of the notes that is, for United States federal income tax purposes, any of the following:

•

an individual who is a citizen or resident of the United States;

•

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

•

an estate the income of which is subject to United States federal income taxation regardless of its source; or

•

a trust if it (i) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (ii) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

As used herein, the term “non-U.S. holder” means a beneficial owner of the notes that is neither a U.S. holder nor an entity or arrangement classified as a partnership for United States federal income tax purposes.

If any entity or arrangement classified as a partnership for United States federal income tax purposes holds the notes, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner in a partnership considering an investment in the notes, you should consult your own tax advisors.

This summary does not represent a detailed description of the United States federal income tax consequences applicable to you if you are a person subject to special tax treatment under the United States federal income tax laws, including, without limitation:

•

a broker or dealer in securities or currencies;

•

a financial institution;

•

a regulated investment company;

•

a real estate investment trust;

•

a tax-exempt entity;

•

an insurance company;

•

a person holding the notes as part of a hedging, integrated, conversion or constructive sale transaction or a straddle;

•

a trader in securities that has elected the mark-to-market method of accounting for your securities;

•

a person liable for alternative minimum tax;

•

a partnership or other pass-through entity for United States federal income tax purposes (or a person who is an investor in such an entity);

•

a U.S. holder that holds notes through a non-U.S. broker or other non-U.S. intermediary;

•

a U.S. holder whose “functional currency” is not the U.S. dollar;

•

a “controlled foreign corporation”;

•

a “passive foreign investment company”;

S-14

TABLE OF CONTENTS

•

a person required to accelerate the recognition of any item of gross income with respect to the notes as a result of such income being recognized on an applicable financial statement; or

•

a United States expatriate.

This summary is based on the Code, United States Treasury regulations, administrative rulings and judicial decisions as of the date hereof. Those authorities may be changed or subject to different interpretations, possibly on a retroactive basis, so as to result in United States federal income tax consequences different from those summarized below. We have not and will not seek any rulings from the Internal Revenue Service (“IRS”) regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of the purchase, ownership or disposition of the notes that are different from those discussed below.

This summary does not address all of the United States federal income tax consequences that may be relevant to you in light of your particular circumstances, nor does it address the Medicare tax on net investment income, United States federal taxes other than income taxes (such as estate and gift taxes) or the effects of any state, local or non-U.S. tax laws. It is not intended to be, and should not be construed to be, legal or tax advice to any particular purchaser of notes.

If you are considering the purchase of notes, you should consult your own tax advisors concerning the particular United States federal income tax consequences to you of the purchase, ownership and disposition of the notes, as well as the consequences to you arising under other United States federal tax laws and the laws of any other taxing jurisdiction.

Certain Tax Consequences to U.S. Holders

The following is a summary of certain United States federal income tax consequences that will apply to you if you are a U.S. holder.

Stated Interest. Stated interest on the notes will generally be taxable to you as ordinary income at the time it is received or accrued, depending on your method of accounting for United States federal income tax purposes. It is expected, and this discussion assumes, that the notes will be issued without original issue discount for United States federal income tax purposes.

Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of Notes. Upon the sale, exchange, retirement, redemption or other taxable disposition of a note, you will generally recognize gain or loss equal to the difference, if any, between the amount realized upon the disposition (less an amount equal to any accrued and unpaid stated interest, which will be taxable as interest income as discussed above to the extent not previously included in income) and your adjusted tax basis in the note. Your adjusted tax basis in a note will generally be your cost for the note. Any gain or loss you recognize will generally be capital gain or loss and will generally be long-term capital gain or loss if you have held the note for more than one year. Long-term capital gains of non-corporate U.S. holders (including individuals) may be eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Certain Tax Consequences to Non-U.S. Holders

The following is a summary of certain United States federal income tax consequences that will apply to you if you are a non-U.S. holder.

United States Federal Withholding Tax. Subject to the discussions of backup withholding and FATCA below, no United States federal income or withholding tax will apply to any payment of interest on the notes under the “portfolio interest rule,” provided that:

•

interest paid on the notes is not effectively connected with your conduct of a trade or business in the United States;

•

you do not actually or constructively own 10% or more of the total combined voting power of all classes of our voting stock within the meaning of the Code and applicable United States Treasury regulations;

S-15

TABLE OF CONTENTS

•

you are not a controlled foreign corporation that is actually or constructively related to us through stock ownership;

•

you are not a bank whose receipt of interest on the notes is described in Section 881(c)(3)(A) of the Code; and

•

either (1) you provide your name and address on an applicable IRS Form W-8, and certify, under penalties of perjury, that you are not a United States person as defined under the Code or (2) you hold your notes through certain foreign intermediaries and satisfy the certification requirements of applicable United States Treasury regulations. Special certification rules apply to non-U.S. holders that are pass-through entities rather than corporations or individuals.

If you cannot satisfy the requirements described above, payments of interest made to you will be subject to a 30% United States federal withholding tax, unless you provide the applicable withholding agent with a properly executed:

•

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

•

IRS Form W-8ECI (or other applicable form) certifying that interest paid on the notes is not subject to withholding tax because it is effectively connected with your conduct of a trade or business in the United States (as discussed below under “— United States Federal Income Tax”).

The 30% United States federal withholding tax generally will not apply to any payment of principal or gain that you realize on the sale, exchange, retirement, redemption or other taxable disposition of a note. You should consult your own tax advisors regarding your entitlement to benefits under an applicable income tax treaty and the requirements for claiming any such benefits.

United States Federal Income Tax. If you are engaged in a trade or business in the United States and interest on the notes is effectively connected with the conduct of that trade or business (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment or fixed base), then you will generally be subject to United States federal income tax on that interest on a net income basis in the same manner as if you were a United States person as defined under the Code (although you will be exempt from the 30% United States federal withholding tax, provided the certification requirements discussed above in “— United States Federal Withholding Tax” are satisfied). In addition, if you are a foreign corporation, you may be subject to a branch profits tax equal to 30% (or a lower rate under an applicable income tax treaty) of your effectively connected earnings and profits, subject to certain adjustments.

Subject to the discussion of backup withholding below, any gain realized on the sale, exchange, retirement, redemption or other taxable disposition of a note generally will not be subject to United States federal income tax unless:

•

the gain is effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment or fixed base), in which case you will generally be subject to United States federal income tax (and possibly branch profits tax) on such gain in the same manner as described above with respect to effectively connected interest; or

•

you are an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met, in which case, you will generally be subject to United States federal income tax at a rate of 30% (or a lower rate under an applicable income tax treaty) on such gain (net of certain United States-source losses).

Information Reporting and Backup Withholding

U.S. Holders. In general, information reporting requirements will apply to payments of interest on the notes and the proceeds of the sale or other taxable disposition (including a retirement or redemption) of a note paid to you (unless in each case you establish that you are an exempt recipient). Backup withholding may apply to such payments if you fail to provide your taxpayer identification number and a certification that you are not subject to backup withholding, or if you have failed to report in full interest and dividend income.

S-16

TABLE OF CONTENTS

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your United States federal income tax liability, provided the required information is timely furnished to the IRS.

Non-U.S. Holders. Interest paid to you and the amount of tax, if any, withheld with respect to those payments will generally be reported to the IRS. 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 you reside under the provisions of an applicable income tax treaty or agreement.

In general, you will not be subject to backup withholding with respect to payments of interest on the notes that we make to you, provided that the applicable withholding agent does not have actual knowledge or reason to know that you are a United States person as defined under the Code, and such withholding agent has received from you the statement described above in the fifth bullet point under “— Certain Tax Consequences to Non-U.S. Holders — United States Federal Withholding Tax.”

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other taxable disposition (including a retirement or redemption) of notes within the United States or conducted through certain United States-related financial intermediaries, unless you certify to the payor under penalties of perjury that you are a non-U.S. holder (and the payor does not have actual knowledge or reason to know that you are a United States person as defined under the Code), or you otherwise establish an exemption.

Foreign Account Tax Compliance Act

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% United States federal withholding tax may apply to any interest paid on the notes to a recipient (whether such recipient is the beneficial owner of the notes or, instead, an intermediary) that is (i) a “foreign financial institution” (as specifically defined in the Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (ii) a “non-financial foreign entity” (as specifically defined in the Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). If an interest payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “— Certain Tax Consequences to Non-U.S. Holders — United States Federal Withholding Tax,” an applicable withholding agent may credit the withholding under FATCA against, and therefore reduce, such other withholding tax. While withholding under FATCA would also have applied to payments of gross proceeds from the sale or other taxable disposition of the notes, proposed United States Treasury regulations (upon which taxpayers may rely until final regulations are issued) eliminate FATCA withholding on payments of gross proceeds entirely. You should consult your own tax advisors regarding these rules and whether they may be relevant to your ownership and disposition of the notes.

TABLE OF CONTENTS

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase of the notes by employee benefit plans that are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or plans, individual retirement accounts or other arrangements that are subject to Section 4975 of the Code or plans that are subject to provisions under any federal, state, local, non-U.S. or other laws, rules or regulations that are similar to such provisions of ERISA or Section 4975 of the Code (collectively, “Similar Laws”), or entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”).

General Fiduciary Matters

ERISA and Section 4975 of the Code impose certain duties on persons who are fiduciaries of a Plan subject to Part 4 Subtitle B of Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”). Under ERISA and Section 4975 of the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in the notes of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code and any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, Section 4975 of the Code and any other applicable Similar Laws.

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person (including a fiduciary of the ERISA Plan) who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. The acquisition and/or holding of notes by an ERISA Plan with respect to which we or the underwriters are considered a party in interest or disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption. In this regard, the United States Department of Labor has issued prohibited transaction class exemptions (“PTCEs”) that may apply to the acquisition and holding of the notes. These class exemptions include, without limitation, PTCE 84-14, regarding transactions effected by independent qualified professional asset managers, PTCE 90-1, regarding transactions by insurance company pooled separate accounts, PTCE 91-38, regarding transactions by bank collective investment funds, PTCE 95-60, regarding transactions by life insurance company general accounts and PTCE 96-23, regarding transactions effected by in-house asset managers, although there can be no assurance that all of the conditions of any such exemptions will be satisfied.

In addition to the foregoing, ERISA and the Internal Revenue Code provides a statutory exemption (Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code) for transactions between an ERISA Plan and a person that is a party in interest and/or a disqualified person (other than a fiduciary or an affiliate that, directly or indirectly, has or exercises discretionary authority or control or renders investment advice with respect to the assets involved in the transaction) solely by reason of providing services to the Plan or by relationship to a service provider, provided that the ERISA Plan fiduciary has made a determination that there is adequate consideration for the transaction.

Because of the foregoing, the notes should not be purchased or held by any person investing “plan assets” of any Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a similar violation of any applicable Similar Laws.

TABLE OF CONTENTS

Representation

By acceptance of a note, or any interest therein, each purchaser and subsequent transferee will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire or hold the notes constitutes assets of any Plan or (ii) the acquisition and holding of the notes by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all-inclusive, nor should it be construed as legal advice. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering acquiring the notes on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of the notes.

The offer of the notes is not a representation by us or the underwriters that an acquisition of the notes by any Plan meets any or all legal requirements applicable to investments by any Plan or that such an investment is appropriate for any particular Plan.

UNDERWRITING

Barclays Capital Inc., Citigroup Global Markets Inc. and SG Americas Securities, LLC are acting as joint book-running managers of the offering and as representatives of the underwriters named in the table below.

Subject to the terms and conditions contained in an underwriting agreement, dated as of the date of this prospectus supplement, between us and the representatives, we have agreed to sell to each underwriter, and each underwriter has severally agreed to purchase from us, the principal amount of notes that appears opposite its name in the table below:

Underwriter

Principal
amount of
20 notes

Barclays Capital Inc.

Citigroup Global Markets Inc.

SG Americas Securities, LLC

Total

The underwriters are offering the notes subject to their acceptance of the notes from us and subject to prior sale. The underwriting 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 certain 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 initially propose to offer the notes to the public at the public offering prices that appear on the cover page of this prospectus supplement. In addition, the underwriters may offer the notes to certain dealers at prices that represent a concession not in excess of % and % of the principal amount of the 20 notes and the 20 notes, respectively. Any underwriter may allow, and any such dealer may reallow, a concession not in excess of % and % of the principal amount of the 20 notes and the 20 notes, respectively, to certain other dealers. After the initial offering of the notes, the underwriters may from time to time vary the offering prices and other selling terms. The underwriters may offer and sell notes through certain of their affiliates.

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

	Paid by us
Per 20 note			%
Per 20 note			%
Total		$

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

We have also agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.

The notes are a new issue of securities, and there are currently no established trading markets for either series of the notes. We do not intend to apply for either series of the notes to be listed on any securities exchange or to arrange for either series of the notes to be quoted on any quotation system. Certain of the underwriters have advised us that they intend to make a market in each series of the notes, but they are not obligated to do so. Such underwriters may discontinue any market making in either series of notes at any time at their sole discretion. Accordingly, we cannot assure you that liquid trading markets 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.

S-20

TABLE OF CONTENTS

In connection with the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the prices of the notes. Specifically, the underwriters may overallot in connection with the offering of the notes, creating syndicate short positions. In addition, the underwriters 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 underwriters are not required to engage in any of these activities, and may end any of them at any time.

Extended Settlement

We expect to deliver the notes against payment for the notes on or about the date specified in the last paragraph of the cover page of this prospectus supplement, which will be the business day following the date of the pricing of the notes (such settlement cycle being referred to as “T+ ”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the business day before the delivery of the notes hereunder will be required, by virtue of the fact that the notes initially will settle in T+ , to specify alternative settlement arrangements to prevent a failed settlement.

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. Certain of the underwriters and their affiliates have provided in the past to us and our affiliates and may provide from time to time in the future, various financial advisory and/or derivatives, commercial banking, investment banking and other commercial transactions and services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions.

Certain of the underwriters and/or their respective affiliates are parties to and lenders under our existing credit facilities. In addition, in the ordinary course of their 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of the underwriters and/or their respective affiliates that have a lending relationship with us routinely hedge, and certain other of the underwriters and/or their respective affiliates that have a lending relationship with us may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and/or their respective 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. The underwriters and/or their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Accordingly, the notes may not be offered or sold, directly or indirectly, nor may any offering material or advertisement in connection with the notes (including this prospectus supplement and the accompanying prospectus and any amendment or

We may offer under this prospectus our debt securities, common stock, preferred stock, and warrants to purchase debt securities or common stock, or any combination of the foregoing, either separately or together in any combination and as a separate series.

The following description of the terms of these securities sets forth some of the general terms and provisions of securities that we may offer. The particular terms of securities offered by any prospectus supplement and the extent, if any, to which the general terms set forth below do not apply to those securities, will be described in the related prospectus supplement. In addition, if we offer securities in any combination of the above securities, the terms of such combined securities will be described in the applicable prospectus supplement. If the information contained in the prospectus supplement differs from the following description, you should rely on the information in the prospectus supplement to the extent such information differs from the description contained herein. In this “General Description of Securities,” unless otherwise indicated, “we,” “us,” “our,” the “Company” and similar words refer only to Caterpillar Inc. and not any of its subsidiaries.

Description of Debt Securities

We have provided below a summary description of our debt securities. This description is not complete and is qualified in its entirety by reference to the full text of our Indenture, dated as of May 1, 1987, as supplemented (the “Indenture”), between us and U.S. Bank, National Association, as successor trustee (the “Trustee”). You should read the full text of our Indenture, a copy of which has been filed as an exhibit to the registration statement of which this prospectus forms a part. The Indenture is also available for inspection at the office of the Trustee. Definitions of certain terms used in this “Description of Debt Securities” may be found below under “— Certain Restrictive Covenants — Certain Definitions.”

The Indenture under which we will issue debt securities does not limit the amount of debt securities that may be issued and each series of debt securities may differ as to its terms. The debt securities will be unsubordinated and may be issued up to the principal amount that may be authorized by us and may be in any currency or currency unit designated by us.

It is anticipated that the debt securities will be “book-entry,” represented by a permanent global certificate registered in the name of The Depository Trust Company or its nominee. However, we reserve the right to issue the securities in certificate form registered in the name of the security holders.

Exchange, Registration, Transfer, and Payment

Principal and interest on the debt securities will be payable, and the exchange or transfer of debt securities will be registrable, at a location designated in the prospectus supplement. No service charge will be applied for a registration of transfer or exchange of debt securities except to cover tax or any governmental charge.

Certain Restrictive Covenants

Unless the applicable prospectus supplement otherwise provides, we will be required to comply with certain restrictive covenants described below. These covenants apply to us and our Restricted Subsidiaries (as defined below).

TABLE OF CONTENTS

Certain Definitions

Consolidated Net Tangible Assets: means as of any particular time the aggregate amount of assets after deducting therefrom (a) all current liabilities (excluding any such liability that by its terms is extendible or renewable at the option of the obligor thereon to a time more than 12 months after the time as of which the amount thereof is being computed) and (b) all goodwill, excess of cost over assets acquired, patents, copyrights, trademarks, trade names, unamortized debt discount and expense and other like intangibles, all as shown in the most recent consolidated financial statements of the Company and its consolidated subsidiaries prepared in accordance with generally accepted accounting principles.

Important Property: means any manufacturing plant or other facility of the Company or any Restricted Subsidiary, whether now owned or hereafter acquired (other than any facility hereafter acquired for the control or abatement of atmospheric pollutants or contaminants, water pollution, noise, odor or other pollution), located in the United States of America, Canada or the Commonwealth of Puerto Rico and having a gross book value (without deduction for depreciation) as of the date of determination of such value in excess of 1% of Consolidated Net Tangible Assets as of such date, other than any such manufacturing plant or other facility that in the opinion of the board of directors of the Company, is not of material importance to the total business conducted by the Company and its Restricted Subsidiaries as a whole.

Restricted Subsidiary: means (a) any Subsidiary other than an Unrestricted Subsidiary and (b) any Unrestricted Subsidiary which, subsequent to May 1, 1987, is designated by the board of directors as a Restricted Subsidiary; provided, however, that as a result of such designation no covenant or agreement in the Indenture would be breached.

Restrictions on Secured Debt

The Indenture prohibits us and our Restricted Subsidiaries from creating Secured Debt (without securing the debt securities equally and ratably with Secured Debt), with the following exceptions:

•

certain mortgages, pledges, liens, security interests or encumbrances to secure payment of all or part of the cost of acquisition, construction or improvement of our property or the property of a Restricted Subsidiary;

•

mortgages, pledges, liens, security interests or encumbrances on property acquired, whether or not assumed by us or a Restricted Subsidiary;

TABLE OF CONTENTS

•

mortgages, pledges, liens, security interests or encumbrances on property, stock, or indebtedness of a Restricted Subsidiary at the time it becomes a Restricted Subsidiary;

•

mortgages, pledges, liens, security interests or encumbrances on property of a corporation merged with us or a Restricted Subsidiary or at the time of a disposition of substantially all of the property of another corporation to us or a Restricted Subsidiary;

•

mortgages, pledges, liens, security interests, or encumbrances on our property or the property of a Restricted Subsidiary in favor of a governmental entity pursuant to contract or statute or to secure certain indebtedness;

•

extensions, renewals or replacements of any mortgage, pledge, lien, security interest or encumbrance referred to above; or

•

any mortgage, pledge, lien, security interest, or encumbrance securing debt owed by us or a Restricted Subsidiary to us or a Restricted Subsidiary.

In addition to these exceptions, we or a Restricted Subsidiary may create, assume, or guarantee other Secured Debt without securing the debt securities if the total amount of Secured Debt outstanding and value of Sale and Leaseback Transactions at the time does not exceed 10% of Consolidated Net Tangible Assets.

Restrictions on Sale and Leaseback Transactions

The Indenture does not permit us or our Restricted Subsidiaries to sell or transfer (except to us or a Restricted Subsidiary) any Important Property we own with the intention of taking back a lease on the property, except for a lease not exceeding three years (a “Sale and Leaseback Transaction”), with the following exceptions:

•

if we or a Restricted Subsidiary could incur Secured Debt equal to the amount received on a sale or transfer secured by a mortgage on the property to be leased without equally and ratably securing the debt securities; or

•

if we or a Restricted Subsidiary apply an amount equal to the value of the property leased to the retirement, within 120 days after the effective date of the arrangement, of indebtedness for money borrowed by us or a Restricted Subsidiary recorded as funded debt as of the date of its creation and which, in the case of indebtedness of us, is not subordinated in right of payment to the prior payment of the debt securities. The amount applied to the retirement of that indebtedness shall be reduced by (i) the principal amount of any debt securities delivered within 120 days of the effective date of any such arrangement to the Trustee for retirement and cancellation, and (ii) the principal amount of the indebtedness, other than debt securities, retired by us or a Restricted Subsidiary within 120 days of the effective date of any such arrangement. No such retirement may be effected by payment at maturity or pursuant to a mandatory prepayment provision.

Restriction on Transfer of Important Property

Neither we nor a Restricted Subsidiary can transfer Important Property to an Unrestricted Subsidiary except in limited circumstances. The transfer can occur if we apply an amount equal to the fair value of the property at the time of transfer (as determined by our board of directors) to the retirement of indebtedness of us or a Restricted Subsidiary (other than such indebtedness owed to us or any Restricted Subsidiary) that is recorded as funded debt and is not subordinated in right of payment to the debt securities. The debt retirement must occur within 120 days of the transfer. No such retirement may be effected pursuant to a mandatory prepayment provision.

Events of Default

Unless we indicate otherwise in a prospectus supplement, the following events are defined in the Indenture as “Events of Default” regarding the debt securities of any series:

•

failure to pay interest on any debt securities when due, continued for 60 days;

TABLE OF CONTENTS

•

failure to pay principal of or premium, if any, on any debt securities when due;

•

failure to deposit any sinking fund payment when due;

•

failure to perform, breach or default of any other covenant or warranty in the Indenture for 60 days after we have received written notice of such failure, breach or default in accordance with the Indenture;

•

certain events in bankruptcy, insolvency or reorganization; and

•

any other Event of Default set forth in the applicable prospectus supplement.

Unless stated otherwise in a prospectus supplement, any Event of Default on a particular series of debt securities is not necessarily an Event of Default on another series of debt securities.

If an Event of Default occurs on outstanding debt securities of a particular series and continues, the Trustee or holders of at least 25% of that series’ debt securities may declare the principal amount of all debt securities in the series due and payable. Subject to any terms or conditions specified in the applicable prospectus supplement, if an Event of Default results from bankruptcy, insolvency or reorganization, the principal amount of all the debt securities of a series will automatically become immediately due and payable. Under certain circumstances, holders of a majority of the debt securities in the series may rescind that declaration and its consequences.

The Trustee must within 90 days after a default occurs notify the holders of debt securities of that series of the default if we have not remedied it. The Trustee may withhold notice to the holders of any default (except with respect to the payment of principal or interest) under certain circumstances if it in good faith considers such withholding to be in the interest of holders. We are required to file an annual certificate with the Trustee, signed by an officer, about any default by us under any provisions of the Indenture.

Subject to the provisions of the Indenture relating to its duties in case of default, the Trustee shall be under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any holders unless such holders offer the Trustee reasonable indemnity. Subject to the provisions for indemnification and other terms of the Indenture, the holders of a majority in principal amount of the debt securities of a series may direct the time, method and place of conducting any proceedings for any remedy available to, or exercising any trust or power conferred on, the Trustee with respect to such debt securities.

Modification of Indenture

Under the Indenture, our rights and obligations and the rights of the holders of debt securities may be changed. Certain changes require the consent of the holders of not less than 662∕3% in aggregate principal amount of the outstanding debt of all series to be affected. However, the following changes may not be made without the consent of each holder of the debt securities:

•

changes to the stated maturity date of the principal or any interest installment;

•

reductions in the principal amount or rate of interest due or any premium payable;

•

changes to the place or currency of payment;

•

impairment of the right to institute suit for the enforcement of payment on or after the stated maturity thereof (or, in the case of redemption, on or after the redemption date);

•

reduction in the stated percentage of holders whose consent is necessary to modify the Indenture; or

•

modifications to any of the requirements for consent of holders of the debt securities to enter into certain supplemental indentures, the requirements to waive compliance with certain provisions of the Indenture or the requirements for a waiver of certain defaults.

TABLE OF CONTENTS

Consolidation, Merger, or Sale

We cannot consolidate or merge with any other person or convey, transfer or lease our properties and assets substantially as an entirety to any other person, unless:

•

we are the continuing corporation or the successor corporation is a domestic corporation and expressly assumes, by supplemental indenture, the due and punctual payment of principal of (and premium, if any) and interest on the debt securities and the performance and observance of every covenant of the Indenture binding on us;

•

immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of ours or a Subsidiary as a result of such transaction as having been incurred by us or such Subsidiary at the time of such transaction, we, that person or that successor corporation will not be in default under the Indenture; and

•

if, as a result of the transaction we become subject to a mortgage, pledge, lien, security interest or other encumbrance not permitted by the Indenture, we or the successor corporation take steps necessary to secure the debt securities equally and ratably with all indebtedness secured thereby.

Other than as described above or in any prospectus supplement, there are no covenants or other provisions in the Indenture that would afford holders of our debt securities additional protection in the event of a recapitalization transaction, a change of control of the Company or a highly leveraged transaction. The merger covenant described above would only apply if the recapitalization transaction, change of control or highly leveraged transaction were structured to include our merger or consolidation or a sale, lease or conveyance of all or substantially all of our assets.

Defeasance

Under certain circumstances we may be discharged from our obligations on the debt securities of a series at any time before the stated maturity if we deposit with the Trustee money or certain equivalents sufficient to pay principal of and interest on the debt securities. One condition for such defeasance, among others as described in the Indenture, is that we must deliver to the Trustee an opinion of counsel that holders of the debt securities will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance.

Book-Entry Issuance and Global Securities

Unless otherwise specified in the applicable prospectus supplement, the Depository Trust Company (“DTC”), New York, New York, will act as securities depository for the securities. The securities will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. Upon issuance, all book-entry securities of the same issue will be represented by one or more fully registered global securities. Each global security will be deposited with, or on behalf of, DTC and DTC will thus be the only registered holder of these securities and will be considered the sole owner of the securities.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of each actual purchaser of each security (“beneficial owner”) is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the securities are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in securities, except in the event that use of the book-entry system for the securities is discontinued. The laws of some jurisdictions require some purchasers of securities to take physical delivery of their securities in definitive or paper form. These laws may impair the ability to transfer book-entry securities.

Unless otherwise specified in the prospectus supplement with respect to a series of debt securities, beneficial owners of book-entry securities represented by a global security may exchange the securities for definitive or paper securities only if:

TABLE OF CONTENTS

•

DTC is unwilling or unable to continue as a depository for such global security and Caterpillar is unable to find a qualified replacement for DTC within 90 days;

•

At any time, DTC ceases to be a “clearing agency” registered under the Securities Act of 1934;

•

Caterpillar, in its sole discretion, decides to allow some or all book-entry securities to be exchangeable for definitive or paper securities in registered form; or

•

For debt securities, there is a continuing Event of Default as further described above.

Any global security that is exchangeable will be exchangeable in whole for definitive securities in registered form with the same terms, and in the case of debt securities, in an equal aggregate principal amount in denominations of $1,000 and whole multiples of $1,000, unless otherwise specified in the applicable prospectus supplement. Definitive securities will be registered in the name or names of the person or persons specified by DTC in a written instruction to the registrar of the securities. DTC may base its written instruction upon directions it receives from its participants.

In this prospectus and the accompanying prospectus supplement for book-entry securities, references to actions taken by security holders will mean actions taken by DTC upon instructions from its participants, and references to payments and notices of redemption to security holders will mean payments and notices of redemption to DTC as the registered holder of the securities for distribution to participants in accordance with DTC’s procedures.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. The rules applicable to DTC and its participants are on file with the SEC.

Caterpillar will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the book-entry securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

TABLE OF CONTENTS

Possible Anti-Takeover Provisions

Shares of our authorized and unissued common stock and preferred stock could (within the limits imposed by applicable law and any applicable rules of the New York Stock Exchange) be issued in one or more transactions or preferred stock could be issued with terms, provisions and rights which would make a takeover of the Company more difficult or more costly and, therefore, less likely. For example, the board of directors may issue such capital stock to a holder or holders who might thereby obtain sufficient voting power, either by voting with the common stock or separately as a class, to defeat or delay a proposed business combination which may be opposed by the board of directors, or to assure that any proposal to remove directors, or to alter, amend or repeal certain provisions in our restated certificate of incorporation would not receive the required stockholder vote or any class vote which would be required to effect such changes. Any such issuance of additional stock could be effected by the board of directors acting alone without further stockholder approval.

Certain provisions of our restated certificate of incorporation and amended and restated bylaws could make more difficult certain unsolicited or hostile attempts to take over the Company, as described below.

Our restated certificate of incorporation and our amended and restated bylaws provide that no action shall be taken by stockholders by written consent and that a special meeting of the stockholders may be called only by the Chairman of the board of directors, the chief executive officer, the secretary, or the board of directors pursuant to a resolution approved by a majority of the entire board of directors, or by stockholders representing in the aggregate not less than 25% of the total number of shares of stock entitled to vote.

Our restated certificate of incorporation and amended and restated bylaws provide that vacancies on the board of directors shall be filled by the affirmative vote of a majority of the remaining directors then in office and not by the stockholders. Our restated certificate of incorporation and amended and restated bylaws further provide certain advance notice requirements in connection with stockholder nominations for the election of directors and other matters to be properly brought before an annual or special meeting by a stockholder.

Section 203 (the “Anti-Takeover Law”) of the Delaware General Corporation Law (the “DGCL”) prevents, subject to certain exceptions, certain Delaware corporations from engaging, under certain circumstances, in a “business combination” (which includes a merger or sale of more than 10% of the corporation’s assets) with any “interested stockholder” (a stockholder who owns 15% or more of the corporation’s outstanding voting stock) for three years following the date that such stockholder became an “interested stockholder.” A Delaware corporation may “opt out” of the Anti-Takeover Law with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from an amendment approved by at least a majority of the outstanding voting shares. The Company is a Delaware corporation that is covered by the Anti-Takeover Law and has not “opted out” of its provisions.

In addition, our amended and restated bylaws provide that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim against the Company or any director or officer or other employee of the Company arising pursuant to any provision of the DGCL or the Company’s restated certificate of incorporation or amended and restated bylaws (as either may be amended from time to time) or (iv) any action asserting a claim against the Company or any director or officer or other employee of the Company governed by the internal affairs doctrine. Our amended and restated bylaws also provide that any person (including any entity) purchasing or otherwise acquiring any interest in shares of capital stock of the Company will be deemed to have notice of and consented to the exclusive forum provisions described above.

TABLE OF CONTENTS

Description of Warrants

We have provided below a summary description of warrants that we may issue. This description is not complete and is qualified in its entirety by reference to the full text of the applicable warrant agreement. You should read the full text of any such warrant agreement.

We may issue warrants, in one or more series, for the purchase of debt securities or shares of our common stock. Warrants may be issued independently or together with our debt securities or common stock and may be attached to or separate from any offered securities. In addition to this summary, you should refer to the detailed provisions of the specific warrant agreement for complete terms of the warrants. Unless otherwise specified in a prospectus supplement accompanying this prospectus, each warrant agreement will be between Caterpillar and a banking institution organized under the laws of the United States or a state thereof as warrant agent. A form of warrant agreement will be filed with the SEC as an exhibit to the Registration Statement by post-effective amendment or a Current Report on Form 8-K.

The warrants will be evidenced by warrant certificates. Unless otherwise specified in the prospectus supplement, the warrant certificates may be traded separately from the debt securities or common stock, if any, with which the warrant certificates were issued. Warrant certificates may be exchanged for new warrant certificates of different denominations at the office of an agent that we will appoint. Until a warrant is exercised, the holder of a warrant does not have any of the rights of a holder of our debt securities or common stock and is not entitled to any payments on any debt securities or common stock issuable upon exercise of the warrants.

A prospectus supplement accompanying this prospectus relating to a particular series of warrants to issue debt securities or common stock will describe the terms of those warrants, including:

•

the title and the aggregate number of warrants;

•

the offering price for such warrants;

•

the debt securities or common stock for which each warrant is exercisable;

•

the date or dates on which the right to exercise such warrants commence and expire;

•

the price or prices at which such warrants are exercisable;

•

the terms of any antidilution or other adjustment provisions;

•

the currency or currencies in which such warrants are exercisable;

•

the periods during which and places at which such warrants are exercisable;

•

the terms of any mandatory or optional call provisions;

•

the price or prices, if any, at which the warrants may be redeemed at the option of the holder or will be redeemed upon expiration;

•

the identity of the warrant agent;

•

the exchanges, if any, on which such warrants may be listed; and

•

any additional terms of such warrants.

You may exercise warrants by payment to our warrant agent of the exercise price, in each case in such currency or currencies as are specified in the warrant, and by giving your identity and the number of warrants to be exercised. Once you pay our warrant agent and deliver the properly completed and executed warrant certificate to our warrant agent at the specified office, our warrant agent will, as soon as practicable, forward securities to you in authorized denominations or share amounts. If you exercise less than all of the warrants evidenced by your warrant certificate, you will be issued a new warrant certificate for the remaining amount of warrants.

Governing Law

Unless otherwise stated in the applicable prospectus supplement, each issue of warrants and the applicable warrant agreement will be governed either by the laws of the State of New York or the laws of the State of Delaware.

TABLE OF CONTENTS

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. The applicable prospectus supplement will describe:

•

the terms of the units and of the securities comprising the units, including whether and under what circumstances the securities comprising the units may be traded separately;

•

a description of the terms of any unit agreement governing the units; and

•

a description of the provisions for the payment, settlement, transfer or exchange of the units or the securities comprising the units.

PLAN OF DISTRIBUTION

We may sell the securities:

•

to or through underwriters or dealers for resale;

•

through agents; or

•

directly to other purchasers.

The related prospectus supplement will set forth the terms of the offering of the securities, including the following:

•

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

•

the purchase price and the proceeds we will receive from the sale;

•

any underwriting discounts or commissions and other items constituting underwriters’ compensation; and

•

any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If underwriters are used in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase securities will be subject to conditions precedent, and the underwriters will be obligated to purchase all the securities of a series if any are purchased. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

We also may sell the securities in connection with a remarketing upon their purchase, in connection with a redemption or repayment, by a remarketing firm acting as principal for its own account or as our agent. Remarketing firms may be deemed to be underwriters in connection with the securities that they remarket.

We may authorize underwriters to solicit offers by institutions to purchase the securities subject to the underwriting agreement from us, at the public offering price stated in the prospectus supplement under delayed delivery contracts providing for payment and delivery on a specified date in the future. If we sell securities under these delayed delivery contracts, the prospectus supplement will state that as well as the conditions to which these delayed delivery contracts will be subject and the commissions payable for that solicitation. If dealers acting as principals are used in the sale of any securities, such securities will be acquired by the dealers, as principals, and may be resold from time to time in one or more transactions at varying prices to be determined by the dealer at the time of resale. The name of any dealer and the terms of the transactions, including any discounts or commissions payable to the dealer, will be set forth in the applicable prospectus supplement with respect to the securities being offered.

Securities may be sold directly by us or through agents designated by us from time to time. Any agent involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named,

TABLE OF CONTENTS

and any commissions payable by us to that agent will be set forth in the related prospectus supplement. Unless otherwise indicated in the related prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. 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 stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement.

Each series of debt securities, preferred stock or warrants will be a new issue of securities with no established trading market. Underwriters and agents may from time to time purchase and sell the securities described in this prospectus and the relevant prospectus supplement in the secondary market, but are not obligated to do so. No assurance can be given that there will be a secondary market for the securities or liquidity in the secondary market if one develops. From time to time, underwriters and dealers may make a market in the securities.

To facilitate the offering of the securities, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of these securities or any other securities the prices of which may be used to determine payments on these securities. Specifically, the underwriters may over-allot in connection with the offering, creating a short position in the securities for their own accounts. In addition, to cover over-allotments or to stabilize the price of the securities or of any other securities, the underwriters may bid for, and purchase, the securities or any other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering, if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time.

Underwriters named in a prospectus supplement are, and dealers and agents named in a prospectus supplement may be, deemed to be “underwriters” within the meaning of the Securities Act, in connection with the securities offered thereby, and any discounts or commissions they receive from us and any profit on their resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act.

Unless indicated in the applicable prospectus supplement, we do not expect to apply to list the debt securities, preferred stock or warrants on a securities exchange.

We may indemnify agents, dealers and underwriters against certain civil liabilities arising out of this prospectus, including liabilities under the Securities Act, or to contribution with respect to payments which the agents, dealers or underwriters may be required to make relating to those liabilities. Agents, dealers and underwriters may be engaged in transactions with, or perform commercial or investment banking or other services for us, our subsidiaries or affiliates, in the ordinary course of business.

Members of the Financial Industry Regulatory Authority, Inc., or FINRA, may participate in distributions of the offered securities. In compliance with the guidelines of FINRA, as of the date of this prospectus, the maximum discount or commission to be received by any FINRA member or independent broker-dealer may not exceed 8.0% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.

We will estimate our expenses associated with any offering of debt securities, preferred stock, common stock, warrants or any combination thereof in the prospectus supplement relating to such offering.
