The information in this preliminary pricing supplement is not complete and may be changed. This preliminary pricing supplement is not an offer to sell nor does it seek an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

Subject to Completion. Dated September 19, 2018.

We will pay you interest semi-annually on your notes at a rate of 3.30% per annum from and including October     , 2018 to but excluding October     , 2020. We will pay you interest semi-annually on your notes at a rate of 4.00% per annum from and including October     , 2020 to but excluding October     , 2022. We will pay you interest semi-annually on your notes at a rate of 6.00% per annum from and including October     , 2022 to but excluding the stated maturity date (October     , 2023). Interest will be paid on each April      and October     . The first such payment will be made on April     , 2019.

In addition, we may redeem the notes at our option, in whole but not in part, on each January     , April     , July     and October     on or after April     , 2019, upon at least five business days’ prior notice, at a redemption price equal to 100% of the outstanding principal amount plus accrued and unpaid interest to but excluding the redemption date. Although the interest rate will step up during the life of your notes, you may not benefit from such increase in the interest rate if your notes are redeemed prior to the stated maturity date.

The initial price to public set forth above does not include accrued interest, if any. Interest on the notes will accrue from October     , 2018 and must be paid by the purchaser if the notes are delivered after October     , 2018. In addition to offers and sales at the initial price to public, the underwriters may offer the notes from time to time for sale in one or more transactions at market prices prevailing at the time of sale, at prices related to market prices or at negotiated prices.

The return (whether positive or negative) on your investment in notes will depend in part on the issue price you pay for such notes.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

The notes are not bank deposits and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency, nor are they obligations of, or guaranteed by, a bank.

Goldman Sachs may use this prospectus in the initial sale of the notes. In addition, Goldman Sachs & Co. LLC or any other affiliate of Goldman Sachs may use this prospectus in a market-making transaction in the notes after their initial sale. Unless Goldman Sachs or its agent informs the purchaser otherwise in the confirmation of sale, this prospectus is being used in a market-making transaction.

SPECIFIC TERMS OF THE NOTES

This pricing supplement no.    dated September     , 2018 (pricing supplement) and the accompanying prospectus dated July 10, 2017 (accompanying prospectus), relating to the notes, should be read together. Because the notes are part of a series of our debt securities called Medium-Term Notes, Series N, this pricing supplement and the accompanying prospectus should also be read with the accompanying prospectus supplement, dated July 10, 2017 (accompanying prospectus supplement). Terms used but not defined in this pricing supplement have the meanings given to them in the accompanying prospectus or accompanying prospectus supplement, unless the context requires otherwise.

The notes are part of a separate series of our debt securities under our Medium-Term Notes, Series N program governed by our Senior Debt Indenture, dated as of July 16, 2008, as amended, between us and The Bank of New York Mellon, as trustee. This pricing supplement summarizes specific terms that will apply to your notes. The terms of the notes described here supplement those described in the accompanying prospectus supplement and accompanying prospectus and, if the terms described here are inconsistent with those described there, the terms described here are controlling.

ADDITIONAL INFORMATION ABOUT THE NOTES

Book-Entry System

We will issue the notes as a master global note registered in the name of DTC, or its nominee. The sale of the notes will settle in immediately available funds through DTC. You will not be permitted to withdraw the notes from DTC except in the limited situations described in the accompanying prospectus under “Legal Ownership and Book-Entry Issuance — What Is a Global Security? — Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated”. Investors may hold interests in a master global note through organizations that participate, directly or indirectly, in the DTC system.

In addition to this pricing supplement, the following provisions are hereby incorporated into the global master note: the description of New York business day appearing under “Description of Debt Securities We May Offer — Calculations of Interest on Debt Securities — Business Days” in the accompanying prospectus, the description of the following unadjusted business day convention appearing under “Description of Debt Securities We May Offer — Calculations of Interest on Debt Securities — Business Day Conventions” in the accompanying prospectus and the section “Description of Debt Securities We May Offer — Defeasance and Covenant Defeasance” in the accompanying prospectus.

Day Count Convention

As further described under “Description of Debt Securities We May Offer — Calculations of Interest on Debt Securities — Interest Rates and Interest” in the accompanying prospectus, for each interest period the amount of accrued interest will be calculated by multiplying the principal amount of the note by an accrued interest factor for the interest period. The accrued interest factor will be determined by multiplying the per annum interest rate by a factor resulting from the 30/360 (ISDA) day count convention. The factor is the number of days in the interest period in respect of which payment is being made divided by 360, calculated on a formula basis as follows:

where:

“Y₁” is the year, expressed as a number, in which the first day of the interest period falls;

“Y₂” is the year, expressed as a number, in which the day immediately following the last day included in the interest period falls;

“M₁” is the calendar month, expressed as a number, in which the first day of the interest period falls;

“M₂” is the calendar month, expressed as a number, in which the day immediately following the last day included in the interest period falls;

“D₁” is the first calendar day, expressed as a number, of the interest period, unless such number would be 31, in which case D₁ will be 30; and

“D₂” is the calendar day, expressed as a number, immediately following the last day included in the interest period, unless such number would be 31 and D₁ is greater than 29, in which case D₂ will be 30.

When We Can Redeem the Notes

We will be permitted to redeem the notes at our option before their stated maturity, as described below. The notes will not be entitled to the benefit of any sinking fund — that is, we will not deposit money on a regular basis into any separate custodial account to repay your note. In addition, you will not be entitled to require us to buy your note from you before its stated maturity.

We will have the right to redeem the notes at our option, in whole but not in part, on each January    , April    , July     and October     on or after April    , 2019, at a redemption price equal to 100% of the outstanding principal amount plus accrued and unpaid interest to but excluding the redemption date. We will provide not less than five business days’ prior notice in the manner described under “Description of Debt Securities We May Offer — Notices” in the attached prospectus. If the redemption notice is given and funds deposited as required, then interest will cease to accrue on and after the redemption date on the notes. If any redemption date is not a business day, we will pay the redemption price on the next business day without any interest or other payment due to the delay.

What are the Tax Consequences of the Notes

You should carefully consider, among other things, the matters set forth under “United States Taxation” in the accompanying prospectus supplement and the accompanying prospectus. The following discussion summarizes certain of the material U.S. federal income tax consequences of the purchase, beneficial ownership, and disposition of each of the notes. This summary supplements the section “United States Taxation” in the accompanying prospectus supplement and the accompanying prospectus and is subject to the limitations and exceptions set forth therein.

As of the original issue date, the notes should not be treated as issued with “original issue discount” (“OID”) despite the fact that the interest rate on the notes is scheduled to step-up over the term of the notes because Treasury regulations generally deem an issuer to exercise a call option in a manner that minimizes the yield on the debt instrument for purposes of determining whether a debt instrument is issued with OID. The yield on the notes would be minimized if we call the notes immediately before the increase in the interest rate on October    , 2020 and therefore the notes should be treated as maturing on such date for OID purposes. This assumption is made solely for purposes of determining whether the notes are issued with OID for U.S. federal income tax purposes, and is not an indication of our intention to call or not to call the notes at any time. If we do not call the notes prior to the increase in the interest rate then, solely for OID purposes, the notes will be deemed to be reissued at their adjusted issue price on October    , 2020. This deemed issuance should not give rise to taxable gain or loss to holders. The same analysis would apply to the increase in the interest rate on October    , 2022. If the notes are not called on the interest payment date occurring on October    , 2022, then, because the period between the interest payment date on October    , 2022 and the stated maturity date of the notes is one year or less, the notes, upon their deemed reissuance on October    , 2022, could be treated as short-term debt securities for OID purposes (but not for purposes of determining the holding period of your notes). For a discussion of the U.S. federal income tax consequences to a U.S. holder of owning short-term debt securities, please review the section entitled “United States Taxation — Taxation of Debt Securities — United States Holders — Short-Term Debt Securities” in the accompanying prospectus.

Under this approach, and subject to the discussion above regarding short-term debt securities, interest on a note will be taxable to a U.S. holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. holder’s normal method of accounting for tax purposes (regardless of whether we call the notes). Upon the disposition of a note by sale, exchange, redemption or retirement (i.e., if we exercise our right to call the notes or otherwise) or other disposition, a U.S. holder will generally recognize capital gain or loss equal to the difference, if any, between (i) the amount realized on the disposition (other than amounts attributable to accrued but unpaid interest, which would be treated as such) and (ii) the U.S. holder’s adjusted tax basis in the note. A U.S. holder’s adjusted tax basis in a note generally will equal the cost of the note (net of accrued interest) to the U.S. holder. The deductibility of capital losses is subject to significant limitations.

Foreign Account Tax Compliance Act (FATCA) Withholding. Pursuant to Treasury regulations, Foreign Account Tax Compliance Act (FATCA) withholding (as described in “United States Taxation — Taxation of Debt Securities — Foreign Account Tax Compliance Act (FATCA) Withholding” in the accompanying prospectus) will generally apply to obligations that are issued on or after July 1, 2014; therefore, the notes will generally be subject to FATCA withholding. However, according to published guidance, the withholding tax described above will not apply to payments of gross proceeds from the sale, exchange, redemption or other disposition of the notes made before January 1, 2019.

SUPPLEMENTAL PLAN OF DISTRIBUTION

The Goldman Sachs Group, Inc. expects to agree to sell to Goldman Sachs & Co. LLC, and Goldman Sachs & Co. LLC expects to agree to purchase from The Goldman Sachs Group, Inc., the aggregate principal amount of the offered notes specified on the front cover of this pricing supplement. Goldman Sachs & Co. LLC proposes initially to offer the notes to the public at the initial price to public set forth on the cover page of this pricing supplement, and to certain securities dealers at such price less a concession not in excess of    % of the face amount. The original issue price for notes purchased by certain fee-based advisory accounts will vary between    % and 100% of the face amount of the notes. Any sale of a note to a fee-based advisory account at an original issue price below 100% of the face amount will reduce the underwriting discount specified on the cover of this pricing supplement with respect to such note. The original issue price paid by any fee-based advisory account will be reduced by the amount of any fees foregone by the securities dealer or dealers involved in the sale of the notes to such advisory account, but not by more than    % of the face amount of the notes. If all of the offered notes are not sold at the initial price to public, the underwriters and/or dealers may change the offering price and the other selling terms.

In the future, Goldman Sachs & Co. LLC or other affiliates of The Goldman Sachs Group, Inc. may repurchase and resell the offered notes in market-making transactions, with resales being made at prices related to prevailing market prices at the time of resale or at negotiated prices. The Goldman Sachs Group, Inc. estimates that its share of the total offering expenses, excluding underwriting discounts and commissions, will be approximately $            . For more information about the plan of distribution and possible market-making activities, see “Plan of Distribution” in the accompanying prospectus.

We expect to deliver the notes against payment therefor in New York, New York on October    , 2018.

Any notes which are the subject of the offering contemplated by this pricing supplement, the accompanying prospectus and the accompanying prospectus supplement may not be offered, sold or otherwise made available to any retail investor in the European Economic Area. Consequently no key information document required by Regulation (EU) No 1286/2014 (the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. For the purposes of this provision:

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), Goldman Sachs & Co. LLC has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of notes which are the subject of the offering contemplated by this pricing supplement, the accompanying prospectus and the accompanying prospectus supplement to the public in that Relevant Member State except that, with effect from and including the Relevant Implementation Date, an offer of such notes may be made to the public in that Relevant Member State:

provided that no such offer of notes referred to above shall require us or any dealer to publish a prospectus pursuant to Article 3 of the Prospectus Directive.

PS-7

For the purposes of this provision, the expression an “offer of notes to the public” in relation to any notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression “Prospectus Directive” means Directive 2003/71/EC (as amended, including by Directive 2010/73/EU), and includes any relevant implementing measure in the Relevant Member State.

Any invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) in connection with the issue or sale of the notes may only be communicated or caused to be communicated in circumstances in which Section 21(1) of the FSMA does not apply to The Goldman Sachs Group, Inc.

All applicable provisions of the FSMA must be complied with in respect to anything done by any person in relation to the notes in, from or otherwise involving the United Kingdom.

The notes may not be offered or sold in Hong Kong by means of any document other than (i) to “professional investors” as defined in the Securities and Futures Ordinance (Cap. 571 of the Laws of Hong Kong) and any rules made thereunder, or (ii) in other circumstances which do not result in the document being a “prospectus” as defined in the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32 of the Laws of Hong Kong) or which do not constitute an offer to the public within the meaning of that Ordinance; and no advertisement, invitation or document relating to the notes may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere) which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to the notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” as defined in the Securities and Futures Ordinance and any rules made thereunder.
