These statements are based on certain assumptions and analyses made in light of our experience and perception of historical trends, current conditions and expected future developments as well as other factors that we believe are appropriate in the circumstances. While these statements represent our judgment on what the future may hold, and we believe these judgments are reasonable, these statements are not guarantees of any events or financial results.

RISK FACTORS

Investment in the Notes involves risks. In addition to all of the other information contained or incorporated by reference into this prospectus supplement and the accompanying prospectus, you should carefully consider the risk factors set forth below and the risk factors incorporated by reference to our Annual Report on Form 10-K for the year ended December 31, 2017, as updated by our subsequent filings under the Exchange Act that are incorporated by reference herein, including our Quarterly Reports on Form 10-Q and our Current Reports on Form 8-K and any amendments thereof, before investing in the Notes.

Risks Related to the Notes

The Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

The Notes will be obligations exclusively of General Motors Company and not any of our subsidiaries, and none of our subsidiaries will guarantee the Notes. We are a holding company and, accordingly, substantially all of our operations are conducted through subsidiaries, which are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due under the Notes or to provide us with funds to pay our obligations, whether by dividends, distributions, loans or other payments. All claims of creditors (including secured and unsecured creditors and general trade creditors) and preferred stockholders of our subsidiaries will have priority with respect to the assets of such subsidiaries over our claims (and therefore the claims of our creditors, including holders of the Notes) as an equity holder of such subsidiaries. Consequently, the Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries and any subsidiaries that we may in the future acquire or create. Furthermore, even if we were a creditor of any of our subsidiaries, our rights as a creditor would be effectively subordinated to any security interest in the assets of those subsidiaries and would be subordinate to any indebtedness of those subsidiaries senior to that held by us. As of June 30, 2018, we had total consolidated liabilities of approximately $180.0 billion (including consolidated indebtedness of approximately $98.3 billion), of which $11.9 billion constitutes indebtedness of General Motors Company (parent company only) under our existing 3.500% senior notes due 2018, floating rate senior notes due 2020, 4.875% senior notes due 2023, 4.000% senior notes due 2025, 4.200% senior notes due 2027, 5.000% senior notes due 2035, 6.600% senior notes due 2036, 5.150% senior notes due 2038, 6.250% senior notes due 2043, 5.200% senior notes due 2045, 6.750% senior notes due 2046 and 5.400% senior notes due 2048 and substantially all of the remainder of which are liabilities of our subsidiaries.

We conduct substantially all of our operations through our subsidiaries and depend on cash flow from our subsidiaries to meet our obligations. Your right to receive payments on the Notes could be adversely affected if any of our subsidiaries becomes unable to distribute cash to us.

Because we are a holding company and conduct substantially all of our operations through subsidiaries, our cash flow and ability to service debt, including the Notes and our $40.9 billion of other senior notes, will depend to a significant extent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, whether by dividends, distributions or other payments. Our subsidiaries are separate and distinct legal entities and will have no obligation, contingent or otherwise, to pay any amounts due pursuant to the Notes or to make any funds available therefor. The financial condition and operating requirements of our subsidiaries may limit our ability to obtain cash from our subsidiaries. In addition, provisions of law, such as those requiring that dividends be paid only from surplus, could limit the ability of our subsidiaries to make payments or other distributions to us. Furthermore, our subsidiaries could in certain circumstances agree to contractual restrictions on their ability to make distributions. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required payments on our obligations, including the Notes.

S-6

The limited covenants in the Indenture that will govern the Notes will not provide protection against many types of important corporate events and may not protect your investment.

The Indenture will not:

As a result of the foregoing, when evaluating the terms of the Notes, you should be aware that the terms of the Indenture and the Notes will not restrict our ability to engage in, or to otherwise be a party to, a variety of corporate transactions, circumstances and events, such as certain acquisitions, refinancings or recapitalizations, that could substantially and adversely affect our capital structure and the value of the Notes.

Although the Notes are referred to as “senior notes,” the Notes will be unsecured and will be effectively subordinated to any of our secured debt.

The Notes will be our unsecured general obligations and will be effectively subordinated to any existing or future secured debt obligations that we may incur to the extent of the value of the assets securing that debt. If we are involved in a bankruptcy, liquidation, dissolution, reorganization or similar proceeding, or upon a default in payment on, or the acceleration of, our secured debt, our assets will be available to pay obligations on the Notes only after all secured debt has been paid in full from the assets securing such debt. We may not have sufficient assets remaining to pay amounts due on any or all of the Notes then outstanding.

If we default or any of our subsidiaries defaults on obligations to pay indebtedness, we may not be able to make payments on the Notes.

Any default under agreements governing our indebtedness or the indebtedness of our subsidiaries, including any default under our $2.0 billion revolving credit facility, our $4.0 billion revolving credit facility and our $10.5 billion revolving credit facility by us or certain of our subsidiaries, that is not waived by the required lenders, and the remedies sought by the holders of such indebtedness, could prevent us from making (or adversely affect our ability to make) required payments on the Notes and could substantially decrease the market value of the Notes. If we or our subsidiaries are unable to generate sufficient cash flows and we or they are otherwise unable to obtain funds necessary to meet required payments on our or their indebtedness, or if we or they otherwise fail to comply with the various covenants, including any financial and operating covenants, in the instruments governing such indebtedness, we or they could be in default under the terms of the agreements governing such indebtedness. In the event of such default, the holders of such indebtedness could, among other

S-7

things, elect to declare all the funds borrowed thereunder to be due and payable and/or terminate their funding commitments, and we or our subsidiaries could be forced into bankruptcy or liquidation. A default under our or our subsidiaries’ other indebtedness will not constitute a default under the Notes.

There are currently no markets for the Notes, and we cannot assure you that active trading markets for the Notes will develop.

The Notes will be new securities for which there currently are no established markets. The Notes will not be listed on any securities exchange. We can give you no assurance as to whether any trading markets for the Notes will ever develop or continue, as to your ability to sell the Notes or as to the prices at which you may be able to sell your Notes. The liquidity of any market for the Notes of each series will depend on a number of factors, including the number of holders of the Notes, prevailing interest rates, the market for similar securities, ratings on us and our debt securities, general economic conditions and the conditions of the financial markets, recommendations of securities analysts and our own results of operations, financial condition and prospects. The underwriters have informed us that they currently intend to make a market in the Notes of each series. However, they are not obligated to do so and may discontinue such market-making at any time without notice. If no active trading markets develop or continue, you may be unable to resell the Notes at their fair value or at any price.

Even if trading markets do develop, changes in our credit ratings or the debt markets could adversely affect the market prices of the Notes.

The market prices for the Notes will depend on many factors, including, among others:

The prices of the Notes may be adversely affected by unfavorable changes in these factors. The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the Notes regardless of our prospects and financial performance and condition.

In addition, credit rating agencies continually review the ratings they have assigned to companies and debt securities. Negative changes in the ratings assigned to us or our debt securities, including the Notes, could have an adverse effect on the market prices of the Notes.

The amount of interest payable on the Floating Rate Notes is set only once per period based on the three-month LIBOR on the interest determination date, which rate may fluctuate substantially.

In the past, the level of the three-month LIBOR has experienced significant fluctuations. You should note that historical levels, fluctuations and trends of the three-month LIBOR are not necessarily indicative of future levels. Any historical upward or downward trend in the three-month LIBOR is not an indication that the three-month LIBOR is more or less likely to increase or decrease at any time during a floating rate interest period, and you should not take the historical levels of the three-month LIBOR as an indication of its future performance. You should further note that although the actual three-month LIBOR on an interest payment date or at other times during an interest period may be higher than the three-month LIBOR on the applicable interest determination date, you will not benefit from the three-month LIBOR at any time other than on the interest determination date for such interest period. As a result, changes in the three-month LIBOR may not result in a comparable change in the market value of the Floating Rate Notes.

S-8

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR after 2021 may adversely affect the value of the Floating Rate Notes.

Regulators and law enforcement agencies in the United Kingdom and elsewhere are conducting civil and criminal investigations into whether the banks that contribute to the British Bankers’ Association (the “BBA”) in connection with the calculation of the daily U.S. dollar London Interbank Offered Rate (“LIBOR”) may have been under-reporting or otherwise manipulating or attempting to manipulate LIBOR. A number of BBA member banks have entered into settlements with their regulators and law enforcement agencies with respect to this alleged manipulation of LIBOR.

Actions by the BBA, regulators or law enforcement agencies may result in changes to the manner in which LIBOR is determined or the establishment of alternative reference rates. For example, on July 27, 2017, the U.K. Financial Conduct Authority announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. The U.K. Financial Conduct Authority has indicated that it expects that the current panel banks will voluntarily sustain LIBOR until the end of 2021, but they may cease to do so sooner. At this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be enacted in the United Kingdom or elsewhere. Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the trading market for LIBOR-based securities, including the Floating Rate Notes.

If a published three-month LIBOR rate is unavailable at any time after the issue date of the Floating Rate Notes, the rate of interest on the Floating Rate Notes will be determined pursuant to the fallback provisions described in “Description of the Notes—Principal and Interest—Floating Rate Notes.” The application of these provisions may result in lower interest payments than would have been made if three-month LIBOR were available in its current form. The fallback provisions may also be subject to factors that make three-month LIBOR impossible or impracticable to determine. If a published three-month LIBOR is unavailable and an alternative reference rate has not been determined pursuant to the fallback provisions, the rate of interest on the Floating Rate Notes for an interest determination date will be the same as on the immediately preceding interest determination date, and such rate of interest could remain the rate of interest on the Floating Rate Notes for the remaining life of the Floating Rate Notes.

S-9

USE OF PROCEEDS

We expect to receive total net proceeds of approximately $         billion from the issuance of the Notes, after underwriter discounts and payment of our other offering expenses. We intend to use the net proceeds from this offering for general corporate purposes, including the repayment of $1.5 billion aggregate principal amount outstanding of our 3.500% senior notes due October 2, 2018, to pre-fund certain mandatory contributions for our U.K. and Canada pension plans due in 2019 through 2021, and for other general corporate purposes.

Until we use the net proceeds from this offering, we intend to invest the funds in short-term investments, including marketable securities. Our management will have broad discretion in the application of the net proceeds, and the purposes for which the net proceeds are used may change from those described above.

DESCRIPTION OF THE NOTES

General

The Notes offered hereby will be issued as separate series of debt securities pursuant to the indenture (the “Base Indenture”) dated as of September 27, 2013 between GM and The Bank of New York Mellon, as trustee (the “Trustee”), as amended and supplemented by the fifth supplemental indenture (the “Supplemental Indenture”) to be dated on or about                 , 2018 between us and the Trustee. The Base Indenture and the Supplemental Indenture, as amended and supplemented, are together referred to herein as the “Indenture.” The Indenture and the Notes are governed by, and construed in accordance with, the laws of the State of New York, United States.

The following description is a summary of the terms of the Notes being offered. This prospectus supplement and the accompanying prospectus contain descriptions of certain terms of the Notes and the Indenture but do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the Indenture, including the definitions of specified terms used in the Indenture, and to the Trust Indenture Act of 1939, as amended (the “TIA”). This summary supplements the description of the debt securities in the accompanying prospectus and, to the extent it is inconsistent, replaces the description in the accompanying prospectus. We urge you to read the Indenture because it, and not this description, defines your rights as a holder of the Notes.

The Notes will be senior, unsecured obligations of GM and will rank equally with all other unsecured and unsubordinated indebtedness of GM (other than obligations preferred by mandatory provisions of law).

The Floating Rate Notes will mature on                 , 2021.

The 2028 Notes will mature on                 , 2028 and the 2049 Notes will mature on                 , 2049; in each case unless we redeem such Notes prior to their respective maturity dates, as described below under “—Optional Redemption.”

The Notes will be issued in book-entry form only through the facilities of DTC, including its participants, Euroclear Bank S.A./N.V. and Clearstream Banking société anonyme. See “Description of Debt Securities—Book-Entry; Delivery and Form; Global Securities” in the accompanying prospectus.

Principal and Interest

The Floating Rate Notes will initially be limited to $                 aggregate principal amount, the 2028 Notes will initially be limited to $                 aggregate principal amount and the 2049 Notes offered hereby will initially be limited to $                 aggregate principal amount.

Floating Rate Notes

The Floating Rate Notes will bear interest at a floating rate per annum, reset quarterly, equal to three-month LIBOR plus     %. Interest on the Floating Rate Notes will be payable quarterly in arrears on                 ,                  ,                 and                 of each year, with the first payment to be made on                 , 2018 (each a “Floating Rate Notes interest payment date”), to the person in whose name the Floating Rate Notes are registered at the close of business on the date that is 15 calendar days prior to each Floating Rate Notes interest payment date. Interest on the Floating Rate Notes will accrue from and including                 , 2018 or from and including the most recent Floating Rate Notes interest payment date to which interest has been paid or duly provided for. If any Floating Rate Notes interest payment date, other than the maturity date, would otherwise be a day that is not a Business Day, the Floating Rate Notes interest payment date will be postponed to the immediately succeeding day that is a Business Day, except that if that Business Day is in the immediately succeeding calendar month, the

S-12

Floating Rate Notes interest payment date shall be the immediately preceding Business Day. If the maturity date of the Floating Rate Notes falls on a day that is not a Business Day, the payment of principal and interest will be made on the next succeeding Business Day, and no interest on such payment will accrue for the period from and after the maturity date.

The interest rate on the Floating Rate Notes will be reset quarterly on                 ,                 ,                  and                 , commencing on                 , 2018 (each an “interest reset date”); provided that if any interest reset date would otherwise be a day that is not a Business Day, the interest reset date will be postponed to the immediately succeeding day that is a Business Day, except that if that Business Day is in the immediately succeeding calendar month, the interest reset date shall be the immediately preceding Business Day.

The “initial interest reset period” (or “initial interest period”) means the period from and including                 , 2018 to but excluding the first interest reset date. Thereafter, each “interest reset period” (or “interest period”) means the period from and including an interest reset date to but excluding the immediately succeeding interest reset date; provided that the final interest reset period for the Floating Rate Notes will be the period from and including the interest reset date immediately preceding the maturity date of the Floating Rate Notes to but excluding the maturity date. Interest on the Floating Rate Notes will be computed on the basis of the actual number of days elapsed over a 360-day year.

The interest rate for the initial interest reset period means the three-month LIBOR, as determined on                 , 2018, plus     %. Thereafter, the interest rate for any interest period will be the three-month LIBOR, as determined as of the applicable interest determination date (as defined below), plus     %. The interest rate will be reset quarterly on each interest reset date.

The interest rate applicable to each interest period commencing on the related interest reset date, or                 , 2018 in the case of the initial interest period, will be the rate determined as of the applicable interest determination date. The “interest determination date” means (i) in the case of the initial interest period, the second London business day immediately preceding                 , 2018, and (ii) in the case of each interest period after the initial interest period, the second London business day immediately preceding the applicable interest reset date. A “London business day” means a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

The Bank of New York Mellon, or its successor appointed by us, will act as the initial calculation agent (the “calculation agent”). “Three-month LIBOR” means, for any interest period, the rate determined by the calculation agent on the applicable interest determination date in accordance with the following provisions:

S-13

S-14

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 1.986865% (or 0.01986865) being rounded to 1.98687% (or 0.0198687)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). Notwithstanding the foregoing, the interest rate on the Floating Rate Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

All calculations made by the calculation agent shall, in the absence of manifest error, be conclusive for all purposes and binding on us, the Trustee and the holders of the Floating Rate Notes.

Fixed Rate Notes

The 2028 Notes will bear interest at a rate of    % per annum and the 2049 Notes will bear interest at a rate of     % per annum. The 2028 Notes and the 2049 Notes will accrue interest, calculated on the basis of a 360-day year consisting of twelve 30-day months, from                 , 2018, or, in each case, from the most recent interest payment date to which interest has been paid or duly provided for, which will be payable in arrears on                 and                 of each year, in the case of the 2028 Notes, and on                      and                      of each year, in the case of the 2049 Notes, with the first payment to be made on                 , 2019 for the 2028 Notes and on                 , 2019 for the 2049 Notes, to the person in whose name such Notes are registered at the close of business on the                 or                 , as the case may be, in the case of the 2028 Notes, and on the                      or                     , as the case may be, in the case of the 2049 Notes, next preceding the relevant interest payment date.

If any interest payment date, stated maturity date or earlier redemption date for the 2028 Notes or the 2049 Notes falls on a day that is not a Business Day, we will make the required payment of principal, premium, if any, and/or interest on the next Business Day as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and after that interest payment date, stated maturity date or earlier redemption date, as the case may be, to the next Business Day.

All Notes

The Notes will be issued in fully registered form only, in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Amounts due on the respective stated maturity date of the Notes (or, in the case of the 2028 Notes and the 2049 Notes, the earlier redemption date of such Notes) will be payable at the corporate trust office of the Trustee, which at the date hereof is 240 Greenwich Street, New York, NY 10286, Attention: Corporate Trust Administration. We will make payments of principal, premium, if any, and interest in respect of the Notes in book-entry form to DTC in immediately available funds, while disbursement of such payments to owners of beneficial interests in Notes in book-entry form will be made in accordance with the procedures of DTC and its participants in effect from time to time.

The term “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday (i) that is not a day on which banking institutions are authorized or obligated by law, regulation or executive order to close in the City of New York or the city in which the corporate trust office of the Trustee is located and (ii) that, in the case of (and solely in the case of) the Floating Rate Notes, is also a London business day as defined above under “—Floating Rate Notes”).

Further Issuances

The Indenture does not limit the amount of other debt that we may incur. We may, from time to time, without the consent of the holders of the Notes, issue other debt securities under the Base Indenture in addition to

S-15

the Notes. We may also, from time to time, without the consent of the holders of the Notes, increase the principal amount of the Notes that may be issued under the Indenture and issue additional Notes of any series in the future; provided that if any additional notes issued are not fungible with the Notes of a particular series for U.S. federal income tax purposes, the additional notes will have a separate CUSIP number. Any such additional notes of a particular series will have the same terms as the Notes of such series being offered in this offering but may be offered at a different offering price or have a different issue date, initial interest accrual date or initial interest payment date and, in the case of the Floating Rate Notes, may have a different initial interest reset date, initial interest reset period or initial interest determination date, than the Notes being offered in this offering. If issued, these additional notes of a particular series will become part of the same series as the corresponding Notes being offered in this offering, including for purposes of voting, redemptions and offers to purchase.

Optional Redemption

We may not redeem the Floating Rate Notes prior to maturity.

At any time prior to                 , 2028 (the date that is three months prior to their maturity date), we may, at our option, redeem some or all of the 2028 Notes at any time and from time to time at a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest on the principal amount being redeemed to, but not including, the applicable redemption date: (i) 100% of the principal amount of the 2028 Notes to be redeemed; and (ii) as determined by us, the sum of the present values of the remaining scheduled payments of principal and interest on the 2028 Notes to be redeemed (not including any portion of payments of interest accrued as of the applicable redemption date), discounted to the applicable redemption date on a semi-annual basis at a rate equal to the sum of the Treasury Rate plus      basis points.

On or after                 , 2028 (the date that is three months prior to their maturity date) we may, at our option, redeem some or all of the 2028 Notes at any time and from time to time at a redemption price equal to 100% of the principal amount of the 2028 Notes to be redeemed, plus accrued and unpaid interest thereon to, but not including, the applicable redemption date.

At any time prior to                     , 2048 (the date that is six months prior to their maturity date), we may, at our option, redeem some or all of the 2049 Notes at any time and from time to time at a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest on the principal amount being redeemed to, but not including, the applicable redemption date: (i) 100% of the principal amount of the 2049 Notes to be redeemed; and (ii) as determined by us, the sum of the present values of the remaining scheduled payments of principal and interest on the 2049 Notes to be redeemed (not including any portion of payments of interest accrued as of the applicable redemption date), discounted to the applicable redemption date on a semi-annual basis at a rate equal to the sum of the Treasury Rate plus          basis points.

On or after                     , 2048 (the date that is six months prior to their maturity date) we may, at our option, redeem some or all of the 2049 Notes at any time and from time to time at a redemption price equal to 100% of the principal amount of the 2049 Notes to be redeemed, plus accrued and unpaid interest thereon to, but not including, the applicable redemption date.

The redemption prices will be calculated assuming a 360-day year consisting of twelve 30-day months. For purposes of calculating the redemption prices, the following terms will have the meanings set forth below.

“Comparable Treasury Issue” means the United States Treasury security selected by a Reference Treasury Dealer as having an actual or interpolated maturity comparable to the remaining term of the Notes of the applicable series to be redeemed that would be used, at the time of selection and in accordance with customary market practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such Notes.

S-16

“Comparable Treasury Price” means, with respect to any redemption date, as determined by us, (A) the average of the five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations or (B) if we obtain fewer than five Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received.

“Reference Treasury Dealer” means with respect to the 2028 Notes and the 2049 Notes, (i) each of Barclays Capital Inc., Deutsche Bank Securities Inc. and SG Americas Securities, LLC and their respective successors, unless any of them ceases to be a primary United States Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case we will substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer and (ii) two other nationally recognized investment banking firms that are Primary Treasury Dealers as selected by us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by us, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference Treasury Dealer as of 5:00 p.m., New York City time, on the third Business Day preceding that redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated as of the third Business Day preceding the redemption date, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

We will give notice of any redemption, mailed not less than 30 days nor more than 60 days before the applicable redemption date, to each holder of the 2028 Notes or the 2049 Notes to be redeemed at such holder’s email address or physical address appearing in the security register of such Notes. If we redeem less than all of the series of the 2028 Notes or the 2049 Notes, the Trustee will select the particular Notes of such series to be redeemed by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate.

Unless we default in the payment of the redemption price, on and after the applicable redemption date, interest will cease to accrue on the 2028 Notes or the 2049 Notes or portions of such Notes called for redemption.

Certain Covenants

Definitions.    The following definitions shall be applicable to the covenants specified below:

“Attributable Debt” means, at the time of determination as to any lease, the present value (discounted at the actual rate, if stated, or, if no rate is stated, the implicit rate of interest of such lease transaction as determined by our chairman, president or any vice chairman, our chief financial officer, any vice president, our treasurer or any assistant treasurer), calculated using the interval of scheduled rental payments under such lease, of the obligation of the lessee for net rental payments during the remaining term of such lease (excluding any subsequent renewal or other extension options held by the lessee). The term “net rental payments” means, with respect to any lease for any period, the sum of the rental and other payments required to be paid in such period by the lessee thereunder, but not including, however, any amounts required to be paid by such lessee (whether or not designated as rental or additional rental) on account of maintenance and repairs, insurance, taxes, assessments, water rates, indemnities or similar charges required to be paid by such lessee thereunder or any amounts required to be paid by such lessee thereunder contingent upon the amount of sales, earnings or profits or of maintenance and repairs, insurance, taxes, assessments, water rates, indemnities or similar charges; provided, however, that, in the case of any lease which is terminable by the lessee upon the payment of a penalty in an amount which is less than the total discounted net rental payments required to be paid from the later of the first date upon which such lease may be so terminated and the date of the determination of net rental payments, “net rental payments” shall include the then current amount of such penalty from the later of such two dates, and shall exclude the rental payments relating to the remaining period of the lease commencing with the later of such two dates.

“Mortgage” means any mortgage, pledge, lien, security interest, conditional sale or other title retention agreement or other similar encumbrance.

“Principal Domestic Manufacturing Property” means all real property located within the continental United States of America and constituting part of any manufacturing plant or facility owned and operated by us or any Manufacturing Subsidiary, together with such manufacturing plant or facility (including all plumbing, electrical, ventilating, heating, cooling, lighting and other utility systems, ducts and pipes attached to or constituting a part thereof, but excluding all trade fixtures (unless such trade fixtures are attached to the manufacturing plant or facility in a manner that does not permit removal therefrom without causing substantial damage thereto), business machinery, equipment, motorized vehicles, tools, supplies and materials, security systems, cameras, inventory and other personal property and materials), unless, in the opinion of our Board of Directors, such manufacturing plant or facility is not of material importance to the total business conducted by us and our consolidated affiliates as an entity.

“Subsidiary” means any corporation of which at least a majority of the outstanding stock having by the terms thereof ordinary voting power to elect a majority of the board of directors of such corporation (irrespective of whether or not at the time stock of any other class or classes of such corporation shall have or might have voting power by reason of the happening of any contingency) is at the time owned by us, or by one or more Subsidiaries, or by us and one or more Subsidiaries.

Limitation on Liens.    For the benefit of the Notes, we will not, nor will we permit any Manufacturing Subsidiary to, issue or assume any Debt secured by a Mortgage upon any Principal Domestic Manufacturing Property of ours or any Manufacturing Subsidiary or upon any shares of stock or indebtedness of any Manufacturing Subsidiary (whether such Principal Domestic Manufacturing Property, shares of stock or indebtedness are now owned or hereafter acquired) without in any such case effectively providing concurrently with the issuance or assumption of any such Debt that the Notes (together with, if we shall so determine, any other indebtedness of us or such Manufacturing Subsidiary ranking equally with the Notes and then existing or thereafter created) shall be secured equally and ratably with such Debt, unless the aggregate amount of Debt issued or assumed and so secured by Mortgages, together with all other Debt of ours and our Manufacturing Subsidiaries which (if originally issued or assumed at such time) would otherwise be subject to the foregoing restrictions, but not including Debt permitted to be secured under clauses (i) through (vii) of the immediately following paragraph, does not at the time exceed 15% of our Consolidated Tangible Assets.

The above restrictions shall not apply to Debt secured by:

Without in any way limiting the applicability of the covenant defeasance provisions of the Indenture with respect to the Notes, upon our exercise of our option to have covenant defeasance applied to all of the outstanding Notes of any particular series, (i) we shall also be deemed to be released from and may omit to comply with our obligations under the covenants described above under “—Certain Covenants” with respect to such series of Notes and (ii) the failure to comply with any such obligation, covenant, restriction, term or other provision shall not constitute (and shall be deemed not to be or result in) an event of default under the Indenture with respect to such series of Notes on and after the date the conditions described under the caption “Description of Debt Securities—Satisfaction, Discharge and Covenant Defeasance” in the accompanying prospectus are satisfied.

S-20

U.S. FEDERAL TAX CONSIDERATIONS

The following is a general discussion of U.S. generally applicable federal income tax considerations (and in the case of Non-U.S. Holders (as defined below), U.S. federal estate tax considerations) relating to the purchase, ownership and disposition of the Notes. It deals only with Notes purchased in this offering at their “issue price” (the first price at which a substantial amount of the Notes is sold for cash to investors other than to bond houses, brokers or similar persons acting in the capacity of underwriters, placement agents or wholesalers) and that are held as capital assets for U.S. federal income tax purposes (generally, property held for investment).

This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, all as in effect on the date hereof, and all of which are subject to change or to different interpretation, possibly with retroactive effect. It does not address all of the U.S. federal income tax considerations that may be relevant to specific Holders (as defined below) in light of their particular circumstances or to Holders subject to special treatment under U.S. federal income tax law (such as banks or other financial institutions, insurance companies, dealers in securities or other persons that generally mark their securities to market for U.S. federal income tax purposes, tax-exempt entities, retirement plans, regulated investment companies, real estate investment trusts, certain former citizens or residents of the U.S., partnerships or other pass-through entities (or investors therein), persons that hold the Notes as part of a straddle, hedge, conversion or other integrated transaction, non-U.S. trusts and estates that have U.S. beneficiaries, persons subject to the alternative minimum tax, U.S. Holders (as defined below) that have a “functional currency” other than the U.S. dollar, persons 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 any applicable financial statement, “controlled foreign corporations,” or “passive foreign investment companies”). This discussion does not address any U.S. state or local tax considerations, non-U.S. tax considerations, or any U.S. federal tax considerations other than U.S. federal income tax considerations (such as U.S. federal gift tax or, except in the case of Non-U.S. Holders, U.S. federal estate tax considerations).

This summary is for general information only and is not tax advice. This summary is not binding on the Internal Revenue Service (“IRS”) or a court. GM has not sought, and does not intend to seek, any tax opinion from counsel or ruling from the IRS with respect to any of the statements made in this summary, and there can be no assurance that the IRS will not take a position contrary to these statements, or that a contrary position taken by the IRS would not be sustained by a court.

HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX CONSIDERATIONS RELATING TO THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.

As used in this discussion, the term “U.S. Holder” means a beneficial owner of a Note that, for U.S. federal income tax purposes, is (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (iv) a trust (x) with respect to which a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions or (y) that has in effect a valid election under applicable U.S. Treasury regulations to be treated as a U.S. person.

The term “Non-U.S. Holder” means a beneficial owner of a Note that is, for U.S. federal income tax purposes, an individual, corporation, estate or trust that is not a U.S. Holder. For purposes of this “Material U.S. Federal Tax Considerations” section only, the term “Holder” means a U.S. Holder or a Non-U.S. Holder (as those terms are defined herein).

S-21

If an entity treated as a partnership for U.S. federal income tax purposes invests in a Note, the tax treatment of a partner will depend in part upon the status and activities of the entity and of the particular partner. Any such entity should consult its own tax advisor regarding the U.S. federal income tax considerations applicable to it and its partners relating to the purchase, ownership and disposition of the Notes.

U.S. Holders

Stated Interest

In general, stated interest payable on the Notes will be taxable to a U.S. Holder as ordinary interest income when it is received or accrued, in accordance with such U.S. Holder’s method of accounting for U.S. federal income tax purposes.

Original Issue Discount

The Notes are expected to be issued with less than a de minimis amount of OID for U.S. federal income tax purposes. However, if the stated principal amount of any series of Notes exceeds their issue price (as defined above) by at least the de minimis amount, such Notes will be treated as issued with OID. In such event, a U.S. Holder generally will be required to include the OID in its gross income (as ordinary income) as the OID accrues on a constant yield to maturity basis, regardless of its regular method of tax accounting and generally before such U.S. Holder receives any payment attributable to such income.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of the Notes

Upon the sale, exchange, redemption, retirement or other taxable disposition of a Note, a U.S. Holder generally will recognize gain or loss in an amount equal to the difference, if any, between (i) the amount realized on such disposition (i.e., the amount of cash and the fair market value of any property received, excluding amounts attributable to accrued but unpaid stated interest, which will be taxable as ordinary interest income to the extent not previously included in income) and (ii) such U.S. Holder’s “adjusted tax basis” in such Note. A U.S. Holder’s “adjusted tax basis” in a Note is generally the amount such U.S. Holder paid, for such Note, increased by the amount of OID (if any) previously included in income (including in the year of disposition) and decreased by the aggregate amount of payments (other than stated interest) on such Note to date. Any gain or loss so recognized generally will be capital gain or loss and will be long-term capital gain or loss if such U.S. Holder has held such Note for more than one year at the time of such disposition. Net long-term capital gain of certain non-corporate U.S. Holders is generally subject to preferential rates of tax. The deductibility of capital losses is subject to limitations.

Additional Tax on Net Investment Income

An additional tax of 3.8% may be imposed on the “net investment income” of certain U.S. individuals and on the undistributed “net investment income” of certain estates and trusts. Among other items, “net investment income” generally includes payments of interest, accruals of OID and certain net gain from the disposition of investment property. U.S. Holders should consult their own tax advisors with respect to the tax consequences of the rules described above.

Non-U.S. Holders

Payments of Interest and Disposition of Notes

Subject to the discussion below:

S-22

The certification requirements referred to in clause (a) above generally will be satisfied if the Non-U.S. Holder provides the applicable withholding agent with a statement on IRS Form W-8BEN or W-8BEN-E (or a suitable substitute form), signed under penalties of perjury, stating, among other things, that such Non-U.S. Holder is not a U.S. person. U.S. Treasury regulations provide additional rules for a Note held through one or more intermediaries or pass-through entities.

If the requirements set forth in clause (a) above are not satisfied with respect to a Non-U.S. Holder, and subject to the immediately following paragraph, amounts treated as payments of interest generally will be subject to U.S. federal withholding tax at a rate of 30%, unless an applicable tax treaty applies to reduce or eliminate this withholding tax and such Non-U.S. Holder provides the appropriate documentation (generally, IRS Form W-8BEN or W-8BEN-E) to the applicable withholding agent.

If a Non-U.S. Holder is engaged in the conduct of a trade or business in the U.S., and if interest on the Notes, or any gain realized on the sale, exchange, redemption, retirement or other taxable disposition of the Notes, are effectively connected with such trade or business (and, if required by an applicable tax treaty, are attributable to a permanent establishment or fixed base maintained by such Non-U.S. Holder in the United States), such Non-U.S. Holder generally will not be subject to U.S. federal withholding tax on such amounts provided that, in the case of interest, such Non-U.S. Holder provides the appropriate documentation (generally, IRS Form W-8ECI) to the applicable withholding agent. Instead, such Non-U.S. Holder generally will be subject to U.S. federal income tax on a net income basis in substantially the same manner as a U.S. Holder (except as provided by an applicable tax treaty). In addition, a Non-U.S. Holder that is a corporation may be subject to a branch profits tax at the rate of 30% (or a lower rate if provided by an applicable tax treaty) on its effectively connected income for the taxable year, subject to certain adjustments.

Gain realized on the sale, exchange, redemption, retirement or other taxable disposition of a Note that is described in clause (b)(ii) above generally will be subject to a flat 30% U.S. federal income tax (or a lower rate if provided by an applicable tax treaty), which gain may be offset by U.S. source capital losses of the Non-U.S. Holder provided certain other requirements are satisfied.

FATCA Withholding

Provisions in the Code commonly referred to as “FATCA” impose withholding of 30% on payments of interest on the Notes and (for dispositions after December 31, 2018) on gross proceeds of sales or redemptions of the Notes paid to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. An intergovernmental agreement between the United States and an applicable non-U.S. country may modify these requirements. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts

S-23

withheld by filing a U.S. federal income tax return (which may entail a significant administrative burden). Prospective investors should consult their tax advisers regarding the effects of FATCA on their investment in the Notes.

Information Reporting and Backup Withholding

Generally, payments of interest on a Note to a Non-U.S. Holder and the amount of any tax withheld from such payments must be reported annually to the IRS and to such Non-U.S. Holder. Backup withholding will not apply to payments of interest on a Note if the recipient Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E) or otherwise establishes an exemption.

The payment of proceeds from the sale, exchange, redemption, retirement or other taxable disposition of a Note by a Non-U.S. Holder effected through a non-U.S. office of a U.S. broker or of a non-U.S. broker with certain specified U.S. connections may be subject to information reporting, but not backup withholding, unless such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E) or otherwise establishes an exemption. The payment of proceeds from the sale, exchange, redemption, retirement or other disposition of a Note by a Non-U.S. Holder effected through a U.S. office of a broker generally will be subject to information reporting and backup withholding, unless such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E) or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability if the required information is timely furnished to the IRS.

U.S. Federal Estate Tax

An individual Non-U.S. Holder who, for U.S. federal tax purposes, is not a citizen or resident of the U.S. at the time of such Non-U.S. Holder’s death generally will not be subject to U.S. federal estate taxes on any part of the value of a Note; provided that, at the time of such Non-U.S. Holder’s death, (i) such Non-U.S. Holder does not actually or constructively own 10% or more of the combined voting power of all classes of GM’s stock and (ii) amounts treated as interest earned on the Note are not effectively connected with the conduct of a trade or business in the United States by such Non-U.S. Holder.

S-24

UNDERWRITING

Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below, for whom Barclays Capital Inc., Deutsche Bank Securities Inc. and SG Americas Securities, LLC are acting as representatives, have severally agreed to purchase, and we have agreed to sell to each underwriter, the principal amount of the Notes set forth opposite the underwriter’s name.

The underwriting agreement provides that the obligations of the underwriters to purchase the Notes are subject to approval of legal matters by counsel and to other conditions. The underwriters must purchase all the Notes if they purchase any of the Notes. The underwriting agreement also provides that if one or more underwriters default, the purchase commitments of the non-defaulting underwriters may be increased or the offering may be terminated.

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. The underwriters may offer the Notes to selected dealers at the public offering price minus a concession of up to     % of the principal amount of the Floating Rate Notes,     % of the principal amount of the 2028 Notes and    % of the principal amount of the 2049 Notes. In addition, the underwriters may allow, and those selected dealers may reallow, a concession of up to     % of the principal amount of the Floating Rate Notes,     % of the principal amount of the 2028 Notes and     % of the principal amount of the 2049 Notes to certain other dealers. After the initial offering, the underwriters may change the public offering prices and any other selling terms. The underwriters may offer and sell the 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.

We have agreed that we will not, during the period beginning on the date of this prospectus supplement and continuing to and including the closing date of the offering of the Notes, offer, sell, contract to sell or otherwise dispose of any debt securities of the Company or warrants to purchase debt securities of the Company substantially similar to the Notes (other than the sale of the Notes under the underwriting agreement), without the prior written consent of the representatives on behalf of the underwriters.

The Notes will constitute new classes of securities with no established trading market. We do not intend to list the Notes on any national securities exchange. We cannot assure you that the prices at which the Notes will sell in the market after this offering will not be lower than the respective initial offering prices or that an active trading market for the Notes will develop and continue after this offering. The underwriters have advised us that they currently intend to make a market in the Notes of each series. However, they are not obligated to do so and they may discontinue any market-making activities with respect to the Notes at any time without notice. Accordingly, we cannot assure you as to the liquidity of, or the trading market for, the Notes.

S-25

The following table shows the underwriting discounts to be paid to the underwriters by us in connection with this offering. These underwriting discounts are the difference between the public offering prices and the amount the underwriters pay to us to purchase the Notes.

We estimate that our portion of the total expenses of the offering, exclusive of the underwriter discounts payable by us in the offering and reimbursements of certain expenses incurred in connection with the offering, will be $        .

It is expected that delivery of the Notes will be made against payment therefor on or about                     , 2018, which will be the third business day following the date of pricing of the Notes (such settlement cycle being referred to herein as “T+3”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the Notes initially will settle in T+3, 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 those Notes on the date of pricing should consult their own advisor.

In connection with the offering, the underwriters may purchase and sell the Notes in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions and stabilizing purchases.

The underwriters may also 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 representatives have repurchased Notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the Notes. They may also cause the price of the Notes to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

The underwriters are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have in the past performed commercial banking, investment banking and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses and may, from time to time,

S-26

engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. In addition, certain underwriters or their respective affiliates are lenders and/or agents under our revolving credit facilities. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, certain other of the underwriters or their affiliates that have a lending relationship with us are likely to hedge, and certain other of the underwriters or their 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 their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (which may include bank loans and/or credit default swaps) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. In particular, one or more of the underwriters or their respective affiliates may hold a portion of our 3.500% senior notes due 2018, for which they will be entitled to receive a pro rata portion of the proceeds of this offering that is used to finance the repayment of such notes. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the underwriters may be required to make because of any of those liabilities.

FORWARD-LOOKING STATEMENTS

This prospectus and any accompanying prospectus supplement may include or incorporate by reference “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (Securities Act), and Section 21E of the Exchange Act. Our use of words like “anticipate,” “appears,” “approximately,” “believe,” “continue,” “could,” “designed,” “effect,” “estimate,” “evaluate,” “expect,” “forecast,” “goal,” “initiative,” “intend,” “may,” “objective,” “outlook,” “plan,” “potential,” “priorities,” “project,” “pursue,” “seek,” “should,” “target,” “when,” “will,” “would” or the negative of any of those words or other similar expressions is intended to identify forward-looking statements that represent our current judgment about possible future events. All statements included or incorporated by reference in this prospectus and any accompanying prospectus supplement, and in related comments by our management, other than statements of historical facts, including without limitation, statements about future events or financial performance, are forward-looking statements that involve certain risks and uncertainties.

These statements are based on certain assumptions and analyses made in light of our experience and perception of historical trends, current conditions and expected future developments as well as other factors that we believe are appropriate in the circumstances. While these statements represent our judgment on what the future may hold, and we believe these judgments are reasonable, these statements are not guarantees of any events or financial results.

Consequently, all of the forward-looking statements made in this prospectus and any prospectus supplement, as well as all of the forward-looking statements incorporated by reference to our filings under the Exchange Act, are qualified by these cautionary statements and there can be no assurance that the actual results or developments that we anticipate will be realized or, even if realized, that they will have the expected consequences to or effects on us and our subsidiaries or our businesses or operations. We caution investors not to place undue reliance on forward-looking statements. We undertake no obligation to update publicly or otherwise revise any forward-looking statements, whether as a result of new information, future events, or other factors that affect the subject of these statements, except where we are expressly required to do so by law.

OVERVIEW OF OUR CAPITAL STOCK

The following description of the material provisions of our capital stock is based upon our certificate of incorporation, as amended (Certificate of Incorporation), our bylaws, as amended (Bylaws), the warrant agreement for our outstanding warrants and applicable provisions of law, in each case as currently in effect as of the date of this prospectus, and is qualified in its entirety by reference to the provisions of those documents.

Certain provisions of the General Corporation Law of the State of Delaware (the DGCL), our Certificate of Incorporation, and our Bylaws summarized in the following paragraphs may have an anti-takeover effect. This may delay, defer, or prevent a tender offer or takeover attempt that a stockholder might consider in its best interests.

Common Stock

As of January 31, 2017, 1,497,964,557 shares of our common stock were issued and outstanding. The general terms of our common stock are described below within the section of this prospectus entitled “Description of Common Stock.”

Warrants

During 2009, we issued a set of warrants to acquire 136,363,635 shares of common stock that are exercisable at any time prior to 5:00 p.m. New York City time, on July 10, 2019 at an exercise price of $18.33 per share and that are listed on the New York Stock Exchange under the symbol “GM.WS.B.”

As of January 31, 2017, there were a total of 41,873,696 of such warrants outstanding. The number of the warrants and the per share exercise price thereof are subject to adjustment as a result of certain events, including stock splits, reverse stock splits and stock dividends.

Certain Provisions of Our Certificate of Incorporation and Bylaws

Amendments to Our Certificate of Incorporation

Under the DGCL, the affirmative vote of a majority of the outstanding shares entitled to vote thereon and a majority of the outstanding stock of each class entitled to vote thereon is generally required to amend a corporation’s certificate of incorporation. Under the DGCL, the holders of the outstanding shares of a class of our capital stock shall be entitled to vote as a class upon a proposed amendment, whether or not entitled to vote thereon by the certificate of incorporation, if the amendment would:

If any proposed amendment would alter or change the powers, preferences or special rights of one or more series of any class of our capital stock so as to affect them adversely, but shall not so affect the entire class, then only the shares of the series so affected by the amendment shall be considered a separate class for the purposes of this provision.

Vacancies in our Board of Directors

Our Bylaws provide that any vacancy occurring in our board of directors (Board of Directors) for any reason may be filled by a majority of the remaining members of our Board of Directors then in office, even if they do not constitute a quorum. Each director so elected shall hold office for a term expiring at the same time as the terms of the directors serving at the time the director joins the Board of Directors. Each such director shall hold office until his or her successor is elected and qualified, unless the director dies, resigns or otherwise leaves the Board of Directors before then.

Special Meetings of Stockholders

Under our Bylaws, special meetings of stockholders may be called at any time by the chairman of the Board of Directors or by a majority of the members of the Board of Directors. Our Bylaws further provide that the Board of Directors shall call a special meeting upon the written request of the record holders of at least 25%, in the aggregate, of the voting power

5

of the outstanding shares of all classes of shares entitled to vote at such a meeting, subject to requirements and limitations set forth in our Bylaws.

Under the DGCL, written notice of any special meeting must be given not less than 10 nor more than 60 days before the date of the special meeting to each stockholder entitled to vote at such meeting.

Requirements for Notice of Stockholder Director Nominations and Stockholder Business

Under our Bylaws, nominations for the election of directors may be made by the Board of Directors in accordance with the stockholders agreement dated October 15, 2009 among us and the other parties thereto or by any stockholder entitled to vote for the election of directors who complies with the applicable notice and other requirements set forth in our Bylaws.

If a stockholder wishes to bring any business before an annual or special meeting or nominate a person for election to our Board of Directors, our Bylaws contain certain procedures that must be followed for the advance timing required for delivery of stockholder notice of such nomination or other business and the information that such notice must contain.

Proxy Access Nominations

Under our Bylaws, we must include in our proxy statement for an annual meeting the name, together with certain other required information, of any person nominated for the election of directors in compliance with specified provisions in our Bylaws by a single shareholder that satisfies (or by a group of no more than 20 shareholders that satisfy) various notice and other requirements specified in our Bylaws. Among other requirements in our Bylaws, such shareholder or group of shareholders would need to provide evidence verifying that the shareholder or group owns, and has owned continuously for the preceding three years, at least 3% of the issued and outstanding voting shares of the Company. Our Bylaws contain limitations on the maximum number of nominees submitted by shareholders that we would be required to include in our proxy statement for an annual meeting.

Stockholder Action by Written Consent without a Meeting

Our Certificate of Incorporation provides that no action that is required or permitted to be taken by our stockholders at any annual or special meeting of stockholders may be effected by written consent of stockholders in lieu of a meeting except where such consent is signed by the holders of all shares of stock of the Company then outstanding and entitled to vote thereon. Our Bylaws also contain notice and procedural requirements applicable to persons seeking to have the stockholders authorize or take corporate action by written consent without a meeting.

Certain Anti-Takeover Effects of Delaware Law

We are subject to Section 203 of the DGCL. In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in various business combination transactions with any interested stockholder for a period of three years following the time that such person became an interested stockholder, unless:

A “business combination” is defined to include mergers, asset sales, and other transactions resulting in financial benefit to an “interested stockholder.” In general, an “interested stockholder” is a person who owns (or is an affiliate or associate of the corporation and, within the prior three years, did own) 15% or more of the corporation’s voting stock.

However, the restrictions contained in Section 203 will not apply if the business combination is with an interested stockholder who became an interested stockholder before the time that we had a class of voting stock that is either listed on a national securities exchange or held of record by more than 2,000 stockholders.

DESCRIPTION OF DEBT SECURITIES

The debt securities offered by this prospectus will be issued under an indenture dated as of September 27, 2013 between us and The Bank of New York Mellon, as trustee, a copy of which has been filed as an exhibit to the registration statement of which this prospectus is a part and which is incorporated by reference herein, subject to such amendments or supplemental indentures as are adopted from time to time. We have summarized selected provisions of the indenture and the debt securities below. This summary is not complete and is qualified in its entirety by reference to the indenture.

We will describe the particular terms of each series of debt securities we offer in a supplement to this prospectus. If any particular terms of the debt securities described in a prospectus supplement differ from any of the terms described in this prospectus, then the terms described in the applicable prospectus supplement will supersede the terms described in this prospectus. The terms of our debt securities will include those set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939, as amended (the TIA). You should carefully read the summary below, the applicable prospectus supplement and the provisions of the indenture that may be important to you before investing in our debt securities.

Wherever terms are used but not defined in this section of the prospectus, those terms have the meanings assigned to them in the indenture, it being intended that those defined terms will be incorporated herein by reference. For purposes of this section of the prospectus, references to “we,” “our,” “us,” “ourselves,” the “Company,” “General Motors” or “GM” refer to General Motors Company (parent company only) and not any of its subsidiaries.

General Terms

We may issue debt securities at any time and from time to time in one or more series under the indenture. The debt securities that we may issue include senior debt securities, subordinated debt securities, convertible debt securities and exchangeable debt securities. A series of debt securities may be guaranteed by one or more of our subsidiaries. The indenture does not limit the amount of debt securities that may be issued thereunder and will govern debt securities up to the aggregate principal amount that we may authorize from time to time. Any such limit applicable to a particular series of debt securities will be specified in the prospectus supplement relating to that series.

We will describe the specific terms of each series of debt securities being offered in a supplement to this prospectus. These terms may include, but are not limited to, some or all of the following:

7

The indenture does not contain any covenant or other specific provision affording protection to holders of debt securities in the event of a highly leveraged transaction or a change in control of us, except to the limited extent described under “Consolidation, Merger or Sale of Assets.”

Restrictive Covenants

We will describe any restrictive covenants for any series of debt securities in the applicable prospectus supplement for such debt securities.

Satisfaction, Discharge and Covenant Defeasance

We may terminate our obligations with respect to the debt securities of any series under the indenture (with the exception of specified provisions as provided in the indenture), when: (i) either:

8

We may elect at any time to have our obligations under the indenture discharged with respect to any series of debt securities (legal defeasance), unless such series of debt securities was designated as not being defeasible. Legal defeasance means that we will be deemed to have paid and discharged the entire indebtedness represented by debt securities of such series and the provisions of the indenture relating to such series of debt securities shall be satisfied and discharged and shall no longer be in effect, except for:

In addition, we may elect at any time to have our obligations under certain covenants in the indenture and the debt securities released with respect to any series of debt securities (covenant defeasance), unless such series of debt securities was designated as not being defeasible. Any failure to comply with these obligations will not constitute an event of default with respect to the debt securities of such series.

The following are the conditions to the applications of legal defeasance or covenant defeasance to any series of debt securities:

in each case, in the written opinion of a nationally recognized firm of independent certified public accountants, to pay and discharge (1) the principal of (and premium, if any) and interest on such debt

9

securities of such series at the stated maturity or redemption date and (2) any mandatory sinking fund payments applicable to the debt securities of such series on the day on which such payments are due and payable;

Consolidation, Merger or Sale of Assets

The indenture provides that we may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to, any person (including any individual, corporation or partnership), unless:

10

In the event of any such consolidation or merger or any conveyance, transfer or lease of all or substantially all our properties and assets, any such successor will be substituted for, and may exercise every right and power of, us under the indenture with the same effect as if it had been named in the indenture as obligor.

Modification of the Indenture

The indenture contains provisions permitting us and the trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or any supplemental indenture or of modifying in any manner the rights of the holders of the debt securities of any series or of the coupons pertaining to such debt securities under the indenture, with the consent of the holders of not less than a majority in aggregate principal amount of the debt securities of all series at the time outstanding under the indenture which are affected by such supplemental indenture, voting as one class, provided , however , that if there are debt securities of more than one series of equal ranking outstanding under the indenture and if a proposed supplemental indenture shall directly affect the rights of the holder of debt securities of one or more, but less than all, of such series, then the consent only of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series so directly affected, considered as one class, shall be required, provided further that, without the consent of the holder of each outstanding debt security so affected, no such supplemental indenture may:

The indenture contains provisions permitting us and the trustee to enter into supplemental indentures, without the consent of the holders of any debt securities, for any of the following purposes:

11

The indenture also permits us and the trustee to enter into supplemental indentures, without the consent of the holders of any debt securities, to implement certain changes to the indenture if the TIA as in effect at the date of the execution and delivery of the indenture or at any time thereafter becomes amended.

Events of Default

An event of default with respect to debt securities of any series is defined in the indenture as being any one of the following events, unless such event is either inapplicable to a particular series or it is specifically deleted or modified with respect to such series of debt securities:

12

period by us as permitted under the terms of any debt security of that series shall not constitute a failure to pay interest for this purpose;

If an event of default under the indenture with respect to any series of outstanding debt securities occurs and is continuing, then the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of such series may by written notice declare the principal amount of the debt securities of such series (or, if the debt securities of such series are original issue discount securities or indexed securities, such portion of the principal amount of such debt securities as may be specified in the terms thereof) to be due and payable immediately and upon such declaration such principal amount (or specified amount), together with all accrued and unpaid interest thereon, shall become immediately due and payable. If an event of default under the indenture specified in clause (v) above occurs, then the principal amount of all the debt securities of each series then outstanding (or if any such debt securities are original issue discount securities or indexed securities, such portion of the principal amount of such debt securities as may be specified in the terms thereof) will automatically become immediately due and payable, together with all accrued and unpaid interest thereon, without any declaration or other act on the part of the trustee or any holders of the debt securities.

At any time after a declaration of acceleration with respect to debt securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the trustee, the event or events of default giving rise to such declaration of acceleration shall, without further act, be deemed to have been waived, and such declaration and its consequence shall, without further act, be deemed to have been rescinded and annulled if (i) all events of default with respect to debt securities of that series, other than nonpayment of the principal of and accrued and unpaid interest on the debt securities of such series that have become due solely by such declaration of acceleration, have been cured or waived as provided in the indenture, and (ii) we have paid or deposited irrevocably with the trustee a sum sufficient to pay (A) all overdue interest of all debt securities of such series, (B) the principal of (and premium, if any, on) any debt securities of such series that have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such debt securities, (C) to the extent lawful, interest upon overdue interest at the rates borne by the debt securities of such series, unless another rate is provided in such debt securities and (D) certain amounts due to the trustee. The holders of not less than a majority in aggregate principal amount of the outstanding debt securities of any series also have the right to waive past defaults with respect to such series, except a default in paying principal, premium (if any) or interest on any debt security of that series, and except in respect of a covenant or a provision that cannot be modified or amended without the consent of all holders of the outstanding debt securities of that series affected.

The indenture imposes limitations on suits brought by holders of debt securities against us. Except for actions for payment of overdue principal, premium or interest, no holder of any debt security of any series may institute any action against us with respect to the indenture unless:

13

If an event of default shall have occurred and be continuing in respect to any series of debt securities, the holders of a majority in aggregate principal amount of the outstanding debt securities of such series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of such series; provided, however , that if an event of default has occurred and is continuing with respect to more than one series of debt securities of equal ranking, the holders of a majority in aggregate principal amount of the outstanding debt securities of all such series of equal ranking, considered as one class, shall have the right to make such direction, and not the holders of the debt securities of any one of such series of equal ranking; provided, further that (1) such direction shall not be in conflict with any rule of law or with the indenture, and (2) the trustee may take any other action deemed proper by the trustee which is not inconsistent with such direction.

Book-Entry; Delivery and Form; Global Securities

Global Securities

Unless otherwise specified in the applicable prospectus supplement, the debt securities of each series will be issued in the form of one or more global debt securities, in definitive, fully registered form without interest coupons, each of which we refer to as a “global security.” Unless otherwise specified in the applicable prospectus supplement, each such global security will be deposited with the trustee as custodian for The Depository Trust Company (DTC) and registered in the name of a nominee of DTC in New York, New York.

Ownership of beneficial interests in a global security will be limited to persons who have accounts with DTC (DTC participants) or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

Beneficial interests in a global security may not be exchanged for debt securities in physical, certificated form except in the limited circumstances described below.

Book-Entry Procedures for the Global Securities

All interests in the global securities will be subject to the operations and procedures of DTC. We provide the following summary of those operations and procedures solely for the convenience of investors. The operations and procedures of DTC are controlled by that settlement system and may be changed at any time. Neither we, the trustee nor any underwriter is responsible for those operations or procedures.

DTC has advised us that it is:

14

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC’s participants include securities brokers and dealers; banks and trust companies; clearing corporations and other organizations. Indirect access to DTC’s system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC or its nominee is the registered owner of a global security, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the debt security represented by that global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security:

As a result, each investor who owns a beneficial interest in a global security must rely on the procedures of DTC to exercise any rights of a holder of the debt security under the indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

Payments of principal, premium, if any, and interest with respect to the debt securities represented by a global security will be made on behalf of GM by the trustee or other paying agent to DTC or its nominee as the registered holder of the global security. Neither we nor the trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global security, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those interests.

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a global security will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC.

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same-day funds. If the laws of a jurisdiction require that certain persons take physical delivery of securities in definitive form, the ability to transfer beneficial interests in a global security to such persons may be limited. Because DTC can only act on behalf of participants, who in turn act on behalf of others, the ability of a person having a beneficial interest in a global security to pledge its interest to a person or entity that does not participate in the DTC system, or otherwise take actions in respect of its interest, may be affected by the lack of a physical security.

Certificated Debt Securities

A global security may be exchanged for debt securities in physical, certificated form (which would be registered in such names as DTC shall direct) only if:

No Individual Liability of Incorporators, Stockholders, Officers or Directors

The indenture provides that no past, present or future director, officer, stockholder or employee of us, any of our affiliates, or any successor corporation shall have any liability for any obligation, covenant or agreement of us or any guarantor under the indenture or any supplemental indenture or in the debt securities.

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.

Concerning the Trustee

The Bank of New York Mellon is the trustee under the indenture.

The indenture provides that if the trustee has or acquires any conflicting interest within the meaning of the TIA with respect to the debt securities of any series, it must either eliminate such conflicting interest or resign to the extent, in the manner and with the effect, and subject to the conditions, provided in the TIA and the indenture.

DESCRIPTION OF PREFERRED STOCK

Our Certificate of Incorporation authorizes our Board of Directors to create and provide for the issuance of one or more series of preferred stock, par value $0.01 per share, without the approval of our stockholders. Our Board of Directors is authorized to establish from time to time the number of shares to be included in each such series, and to fix the designations, powers, preferences and rights of the shares of each such series and the qualifications, limitations and restrictions thereof. Our Certificate of Incorporation currently authorizes our Board of Directors to issue 2,000,000,000 shares of preferred stock. As of January 31, 2017, there were no shares of preferred stock outstanding. The terms of any shares of preferred stock offered pursuant to this prospectus will be set forth in an applicable prospectus supplement.

DESCRIPTION OF COMMON STOCK

Our only class of common stock is our common stock, par value $0.01 per share. Our Certificate of Incorporation currently authorizes our Board of Directors to issue 5,000,000,000 shares of common stock. As of January 31, 2017 1,497,964,557 shares of our common stock were issued and outstanding. There are no redemption or sinking fund provisions applicable to our common stock. All outstanding shares of our common stock are fully paid and non-assessable.

Dividends

The DGCL and our Certificate of Incorporation do not require our Board of Directors to declare dividends on our common stock. The declaration of any dividend on our common stock is a matter to be acted upon by our Board of Directors in its sole discretion. Our payment of dividends on our common stock in the future will be determined by our Board of Directors in its sole discretion and will depend on business conditions, our financial condition, earnings and liquidity, and other factors.

The DGCL restricts the power of our Board of Directors to declare and pay dividends on our common stock. The amounts which may be declared and paid by our Board of Directors as dividends on our common stock are subject to the amount legally available for the payment of dividends on our common stock by us under the DGCL. In particular, under the DGCL, we can only pay dividends to the extent that we have surplus—the extent by which the fair market value of our net assets exceeds the amount of our capital—or to the extent of our net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. In addition, dividends on our common stock are subject to any preferential rights on any outstanding series of preferred stock authorized for issuance by our Board of Directors in accordance with our Certificate of Incorporation.

Voting Rights

Our Certificate of Incorporation provides that, except as may otherwise be provided in a certificate of designations relating to any outstanding series of preferred stock or by applicable law, the holders of shares of common stock shall be entitled to one vote for each such share upon each matter presented to the stockholders and the common stock shall have the

16

exclusive right to vote for the election of directors and for all other purposes. Our common stockholders do not possess cumulative voting rights.

Under our Bylaws, in uncontested elections of directors, those nominees receiving the affirmative vote of a majority of the votes cast with respect to that director’s election at a meeting at which a quorum is present shall be elected. A majority of votes cast means that the number of votes for a nominee must exceed 50% of the votes cast with respect to the election of that nominee (excluding any abstentions). In certain contested elections, the nominees who receive a plurality of votes cast with respect to the election of directors at a meeting at which a quorum is present shall be elected. Under our Bylaws, any other corporate action put to a stockholder vote shall be decided by the vote of the holders of a majority of the voting power of the shares entitled to vote thereon present in person or by proxy at the meeting, unless otherwise provided by law, rule or regulation, including any stock exchange rule or regulation, applicable to the Company.

Liquidation Rights

In the event of any liquidation, dissolution or winding up of the Company, the holders of our common stock would be entitled to receive, after payment or provision for payment of all of our debts and liabilities, all of our assets available for distribution. Holders of our preferred stock, if any such shares are then outstanding, may have a priority over the holders of common stock in the event of any liquidation or dissolution.

Transfer Agent and Registrar

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

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “GM” and on the Toronto Stock Exchange under the symbol “GMM.”
