Filed Pursuant to Rule 424(b)(2)

Registration Statement Nos. 333-216372 and 333-216372-01

Autocallable Contingent Coupon Equity Linked Securities Based on the Worst Performing of the Shares of the Energy Select Sector SPDR^®Fund and the Shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF Due January 27, 2022

▪

The securities offered by this pricing supplement are unsecured senior debt securities issued by Citigroup Global Markets Holdings Inc. and guaranteed by Citigroup Inc. The securities offer the potential for contingent quarterly coupon payments at an annualized rate that, if all are paid, would produce a yield that is generally higher than the yield on our conventional debt securities of the same maturity. In exchange for this higher potential yield, you must be willing to accept the risks that (i) your actual yield may be lower than the yield on our conventional debt securities of the same maturity because you may not receive one or more, or any, contingent coupon payments; (ii) your actual yield may be negative because you may receive significantly less than the stated principal amount of your securities, and possibly nothing, at maturity; and (iii) the securities may be automatically redeemed prior to maturity beginning approximately one year after the issue date. Each of these risks will depend on the performance of the worst performing of the shares of the Energy Select Sector SPDR^®Fund and the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF (each, the “underlying shares”), as described below. You will be subject to risks associated with each of the underlying shares and will be negatively affected by adverse movements in either of the underlying shares regardless of the performance of any other underlying shares. Although you will be exposed to downside risk with respect to the worst performing underlying shares, you will not participate in any appreciation of the underlying shares or receive any dividends paid on the underlying shares.

▪

Investors in the securities must be willing to accept (i) an investment that may have limited or no liquidity and (ii) the risk of not receiving any payments due under the securities if we and Citigroup Inc. default on our obligations. All payments on the securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.

Additional Information

General. The terms of the securities are set forth in the accompanying product supplement, prospectus supplement and prospectus, as supplemented by this pricing supplement. The accompanying product supplement, prospectus supplement and prospectus contain important disclosures that are not repeated in this pricing supplement. For example, certain events may occur that could affect whether you receive a contingent coupon payment on a contingent coupon payment date as well as your payment at maturity. These events, including market disruption events and other events affecting the underlying shares, and their consequences are described in the accompanying product supplement in the sections “Description of the Securities—Certain Additional Terms for Securities Linked to Company Shares or ETF Shares—Consequences of a Market Disruption Event; Postponement of a Valuation Date,” “—Dilution and Reorganization Adjustments,” and “—Delisting, Liquidation or Termination of an ETF,” and not in this pricing supplement. The accompanying underlying supplement contains important disclosures regarding each of the underlying shares that are not repeated in this pricing supplement. It is important that you read the accompanying product supplement, underlying supplement, prospectus supplement and prospectus together with this pricing supplement in connection with your investment in the securities. Certain terms used but not defined in this pricing supplement are defined in the accompanying product supplement.

Relevant price. With respect to shares of the Energy Select Sector SPDR^® Fund and shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF, the respective initial share price, coupon barrier price and final barrier price are each a “Relevant Price” for purposes of the section “Description of the Securities—Certain Additional Terms for Securities Linked to Company Shares or ETF Shares—Dilution and Reorganization Adjustments” in the accompanying product supplement. Accordingly, the initial share price, the coupon barrier price and the final barrier price with respect to shares of the Energy Select Sector SPDR^® Fund and shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF are each subject to adjustment upon the occurrence of any of the events described in that section.

Postponement of a valuation date. If any valuation date is not a scheduled trading day for either of the underlying shares or if a market disruption event occurs with respect to either of the underlying shares on any valuation date, that valuation date will be subject to postponement as described in the accompanying product supplement in the section “Description of the Securities—Certain Additional Terms for Securities Linked to Company Shares or ETF Shares—Consequences of a Market Disruption Event; Postponement of a Valuation Date.” If any valuation date is postponed, the closing price of each of the underlying shares in respect of that valuation date will be determined based on (i) for either of the underlying shares for which the originally scheduled valuation date is a scheduled trading day and as to which a market disruption event does not occur on the originally scheduled valuation date, the closing price of such underlying shares on the originally scheduled valuation date and (ii) for any other underlying shares, the closing price of such underlying shares on the valuation date as postponed (or, if earlier, the first scheduled trading day for such underlying shares following the originally scheduled valuation date on which a market disruption event did not occur with respect to such underlying shares).

Hypothetical Examples

The examples below illustrate how to determine whether a contingent coupon will be paid with respect to a quarterly valuation date and how to calculate the payment at maturity on the securities, assuming the securities are not automatically redeemed prior to maturity. You should understand that the term of the securities, and your opportunity to receive the contingent coupon payments on the securities, may be limited to as short as approximately one year if the securities are automatically redeemed prior to the maturity date, which is not reflected in the examples below. Unless earlier redeemed, during the term of the securities, there are sixteen valuation dates. For ease of analysis, figures in the table below may have been rounded.

The examples below are based on the following values in order to illustrate how the securities work:

Underlying shares	Initial share price	Coupon barrier price	Final barrier price
Shares of the Energy Select Sector SPDR^® Fund	$78.03	$54.621 (70% of the applicable initial share price)	$54.621 (70% of the applicable initial share price)
Shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF	$39.69	$27.783 (70% of the applicable initial share price)	$27.783 (70% of the applicable initial share price)
Contingent coupon rate:		7.05% per annum, paid quarterly

Hypothetical Examples of Contingent Coupon Payments and any Payment upon Automatic Early Redemption with Respect to a Quarterly Valuation Date that is also a Potential Redemption Date

Set forth below are three hypothetical examples of the calculation of the contingent coupon payment with respect to a hypothetical quarterly valuation date that is also a potential redemption date.

	Hypothetical closing price of the shares of the Energy Select Sector SPDR^®Fund	Hypothetical closing price of the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF	Hypothetical contingent coupon payment per security and any payment upon an automatic early redemption
Example 1: Hypothetical valuation date 1	$66.33 (share performance factor = $66.33 / $78.03 = 0.85)	$29.77 (share performance factor = $29.77 / $39.69 = 0.75)	$17.625
Example 2: Hypothetical valuation date 2	$35.11 (share performance factor = $35.11 / $78.03 = 0.45)	$43.66 (share performance factor = $43.66 / $39.69 = 1.10)	$0.00
Example 3: Hypothetical valuation date 3	$85.83 (share performance factor = $85.83 / $78.03 = 1.10)	$51.60 (share performance factor = $51.60 / $39.69 = 1.30)	*$1,017.625 ($1,000 stated principal amount per security plus* the related contingent coupon payment)**

Example 1: On the hypothetical valuation date, the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF have the lowest share performance factor and, therefore, are the worst performing underlying shares. In this scenario, the closing price of the worst performing underlying shares is greater than the applicable coupon barrier price but less than the applicable initial share price. As a result, investors in the securities would receive the contingent coupon payment of $17.625 per security on the related contingent coupon payment date and the securities would not be automatically called.

Example 2: On the hypothetical valuation date, the shares of the Energy Select Sector SPDR^®Fund have the lowest share performance factor and, therefore, are the worst performing underlying shares. In this scenario, the closing price of the worst performing underlying shares is less than the applicable coupon barrier price and less than the applicable initial share price. As a result, investors would not receive any payment on the related contingent coupon payment date, even though the other underlying shares have appreciated from their applicable initial share price, and the securities would not be automatically called.

Investors in the securities will not receive a contingent coupon payment with respect to a valuation date if, on that valuation date, the closing price of the worst performing underlying shares is less than the applicable coupon barrier price.

Example 3: On the hypothetical valuation date, the hypothetical closing prices of both of the underlying shares are greater than their applicable coupon barrier prices and their applicable initial share prices. In this scenario, the closing price of the worst performing underlying shares is greater than the applicable initial share price and the securities would be automatically redeemed on the related contingent coupon payment date for an amount in cash equal to $1,000 plus the related contingent coupon payment, or $1,017.625. If the valuation date were not also a potential redemption date, the securities would not be automatically redeemed on the related contingent coupon payment date.

Hypothetical Examples of the Payment at Maturity on the Securities

The following examples illustrate the hypothetical payment at maturity on the securities as determined based on the applicable final share prices of the underlying shares on the final valuation date, assuming the securities have not been earlier automatically redeemed.

	Hypothetical final share price of the shares of the Energy Select Sector SPDR^®Fund	Hypothetical final share price of the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF	Hypothetical payment at maturity per security
Example 4	$93.64 (share performance factor = $93.64 / $78.03 = 1.20)	$43.66 (share performance factor = $43.66 / $39.69 = 1.10)	$1,017.625
Example 5	$39.02 (share performance factor = $39.02 / $78.03 = 0.50)	$35.72 (share performance factor = $35.72 / $39.69 = 0.90)	$500.00
Example 6	$15.61 (share performance factor = $15.61 / $78.03 = 0.20)	$47.63 (share performance factor = $47.63 / $39.69 = 1.20)	$200.00

Example 4: In this example, the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF are the worst performing underlying shares. In this scenario, the final share price of the worst performing underlying shares on the final valuation date is greater than the applicable final barrier price. Accordingly, at maturity, you would receive the stated principal amount of the securities plus the contingent coupon payment of $17.625 per security, but you would not participate in the appreciation of either of the underlying shares.

Example 5: In this example, the shares of the Energy Select Sector SPDR^®Fund are the worst performing underlying shares. In this scenario, the final share price of the worst performing underlying shares on the final valuation date is less than the applicable final barrier price. Accordingly, at maturity, you would receive a payment per security calculated as follows:

Payment at maturity = $1,000 × share performance factor of the shares of the Energy Select Sector SPDR^®Fund on the final valuation date

= $1,000 × 0.50

= $500

In this scenario, you would receive significantly less than the stated principal amount of your securities at maturity. You would incur a loss based on the performance of the worst performing underlying shares, even though the final share price of the other underlying shares on the final valuation date is greater than the applicable final barrier price. In addition, because the final share price of the worst performing underlying shares on the final valuation date is below the applicable coupon barrier price, you will not receive any quarterly contingent coupon payment.

Example 6: In this example, the shares of the Energy Select Sector SPDR^®Fund are the worst performing underlying shares and their final share price on the final valuation date is less than the applicable final barrier price. Accordingly, at maturity, you would receive a payment per security calculated as follows:

Payment at maturity = $1,000 × share performance factor of the shares of the Energy Select Sector SPDR^®Fund on the final valuation date

= $1,000 × 0.200

= $200

In this scenario, because the final share price of the worst performing underlying shares on the final valuation date is less than the applicable final barrier price, you would lose a significant portion of your investment in the securities. In addition, because the final share price of the worst performing underlying shares is below the applicable coupon barrier price, you will not receive any quarterly contingent coupon payment. If the closing price of the worst performing underlying shares were less than the applicable coupon barrier price on each valuation date and less than the applicable final barrier price on the final valuation date, you would not have received any quarterly contingent coupon payments and would have received significantly less than the stated principal amount of your securities at maturity.

Summary Risk Factors

An investment in the securities is significantly riskier than an investment in conventional debt securities. The securities are subject to all of the risks associated with an investment in our conventional debt securities (guaranteed by Citigroup Inc.), including the risk that we and Citigroup Inc. may default on our obligations under the securities, and are also subject to risks associated with each of the underlying shares. Accordingly, the securities are suitable only for investors who are capable of understanding the complexities and risks of the securities. You should consult your own financial, tax and legal advisors as to the risks of an investment in the securities and the suitability of the securities in light of your particular circumstances.

The following is a summary of certain key risk factors for investors in the securities. You should read this summary together with the more detailed description of risks relating to an investment in the securities contained in the section “Risk Factors Relating to the Securities” beginning on page EA-6 in the accompanying product supplement. You should also carefully read the risk factors included in the accompanying prospectus supplement and in the documents incorporated by reference in the accompanying prospectus, including Citigroup Inc.’s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which describe risks relating to the business of Citigroup Inc. more generally.

▪

You may lose some or all of your investment. Unlike conventional debt securities, the securities do not provide for the repayment of the stated principal amount at maturity in all circumstances. If the securities are not automatically redeemed prior to maturity, your payment at maturity will depend on the performance of the worst performing underlying shares. If the final share price of the worst performing underlying shares on the final valuation date is less than the applicable final barrier price, you will lose 1% of the stated principal amount of the securities for every 1% by which the final share price of the worst performing underlying shares has declined from the applicable initial share price, regardless of the performance of the other underlying shares. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment.

▪

You will not receive any contingent coupon payment for any quarter in which the closing price of the worst performing underlying shares is less than the applicable coupon barrier price on the related valuation date. A contingent coupon payment will be made on a contingent coupon payment date if and only if the closing price of the worst performing underlying shares on the related valuation date is greater than or equal to the applicable coupon barrier price. If the closing price of the worst performing underlying shares is less than the applicable coupon barrier price on any quarterly valuation date, you will not receive any contingent coupon payment on the related contingent coupon payment date. If the closing price of the worst performing underlying shares is below the applicable coupon barrier price on each valuation date, you will not receive any contingent coupon payments over the term of the securities.

▪

The securities are subject to the risks of both of the underlying shares and will be negatively affected if either of the underlying shares perform poorly, even if the other underlying shares perform well. You are subject to risks associated with each of the underlying shares. If either of the underlying shares perform poorly, you will be negatively affected, even if the other underlying shares perform well. The securities are not linked to a basket composed of the underlying shares, where the better performance of one could ameliorate the poor performance of the other. Instead, you are subject to the full risks of whichever of the underlying shares are the worst performing underlying shares.

▪

You will not benefit in any way from the performance of the better performing underlying shares. The return on the securities depends solely on the performance of the worst performing underlying shares, and you will not benefit in any way from the performance of the better performing underlying shares. The securities may underperform a similar investment in both of the underlying shares or a similar alternative investment linked to a basket composed of the underlying shares, since in either such case the performance of the better performing underlying shares would be blended with the performance of the worst performing underlying shares, resulting in a better return than the return of the worst performing underlying shares.

▪

You will be subject to risks relating to the relationship between the underlying shares. It is preferable from your perspective for the underlying shares to be correlated with each other, in the sense that they tend to increase or decrease at similar times and by similar magnitudes. By investing in the securities, you assume the risk that the underlying shares will not exhibit this relationship. The less correlated the underlying shares, the more likely it is that either one of the underlying shares will perform poorly over the term of the securities. All that is necessary for the securities to perform poorly is for one of the underlying shares to perform poorly; the performance of the underlying shares that are not the worst performing underlying shares is not relevant to your return on the securities. It is impossible to predict what the relationship between the underlying shares will be over the term of the securities.

▪

Higher contingent coupon rates are associated with greater risk. The securities offer contingent coupon payments at an annualized rate that, if all are paid, would produce a yield that is generally higher than the yield on our conventional debt securities of the same maturity. This higher potential yield is associated with greater levels of expected risk as of the pricing date for the securities, including the risk that you may not receive a contingent coupon payment on one or more, or any, contingent coupon payment dates and the risk that you may receive significantly less than the stated principal amount of your securities at maturity. The volatility of and the correlation between the underlying shares are important factors affecting these risks. Greater expected volatility of and lower expected correlation between the underlying shares as of the pricing date may result in a higher contingent coupon rate, but would also represent a greater expected likelihood as of the pricing date that the closing price of the worst performing underlying shares will be less than the applicable coupon barrier price on one or more valuation dates, such that you will not receive one or more, or any, contingent coupon payments during the term of the securities and that the final share price of

the worst performing underlying shares will be less than the applicable final barrier price on the final valuation date, such that you will not be repaid the stated principal amount of your securities at maturity.

▪

You may not be adequately compensated for assuming the downside risk of the worst performing underlying shares. The potential contingent coupon payments on the securities are the compensation you receive for assuming the downside risk of the worst performing underlying shares, as well as all the other risks of the securities. That compensation is effectively “at risk” and may, therefore, be less than you currently anticipate. First, the actual yield you realize on the securities could be lower than you anticipate because the coupon is “contingent” and you may not receive a contingent coupon payment on one or more, or any, of the contingent coupon payment dates. Second, the contingent coupon payments are the compensation you receive not only for the downside risk of the worst performing underlying shares, but also for all of the other risks of the securities, including the risk that the securities may be automatically redeemed beginning approximately one year after the issue date, interest rate risk and our and Citigroup Inc.’s credit risk. If those other risks increase or are otherwise greater than you currently anticipate, the contingent coupon payments may turn out to be inadequate to compensate you for all the risks of the securities, including the downside risk of the worst performing underlying shares.

▪

The securities may be automatically called prior to maturity, limiting your opportunity to receive contingent coupon payments. On any potential redemption date, beginning in January 2019 and ending in October 2021, the securities will be automatically called if the closing price of the worst performing underlying shares on that potential redemption date is greater than or equal to the applicable initial share price. Thus, the term of the securities may be limited to as short as approximately one year. If the securities are called prior to maturity, you will not receive any additional contingent coupon payments. Moreover, you may not be able to reinvest your funds in another investment that provides a similar yield with a similar level of risk.

▪

The securities offer downside exposure to the underlying shares, but no upside exposure to the underlying shares. You will not participate in any appreciation in the value of the underlying shares over the term of the securities. Consequently, your return on the securities will be limited to the contingent coupon payments you receive, if any, and may be significantly less than the return on the underlying shares over the term of the securities. In addition, you will not receive any dividends or other distributions or have any other rights with respect to the underlying shares or the stocks included in or held by, as applicable, either of the underlying shares.

▪

The performance of the securities will depend on the closing prices of the underlying shares solely on the relevant valuation dates, which makes the securities particularly sensitive to the volatility of the underlying shares. Whether the contingent coupon will be paid for any given quarter and whether the securities will be automatically redeemed prior to maturity will depend on the closing prices of the underlying shares solely on the applicable quarterly valuation dates, regardless of the closing prices of the underlying shares on other days during the term of the securities. If the securities are not automatically redeemed, what you receive at maturity will depend solely on the final share price of the worst performing underlying shares on the final valuation date, and not on any other day during the term of the securities. Because the performance of the securities depends on the closing prices of the underlying shares on a limited number of dates, the securities will be particularly sensitive to volatility in the closing prices of the underlying shares. You should understand that each of the underlying shares have historically been highly volatile.

▪

The securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. If we default on our obligations under the securities and Citigroup Inc. defaults on its guarantee obligations, you may not receive any amounts owed to you under the securities.

▪

The securities will not be listed on any securities exchange and you may not be able to sell them prior to maturity. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. CGMI currently intends to make a secondary market in relation to the securities and to provide an indicative bid price for the securities on a daily basis. Any indicative bid price for the securities provided by CGMI will be determined in CGMI’s sole discretion, taking into account prevailing market conditions and other relevant factors, and will not be a representation by CGMI that the securities can be sold at that price, or at all. CGMI may suspend or terminate making a market and providing indicative bid prices without notice, at any time and for any reason. If CGMI suspends or terminates making a market, there may be no secondary market at all for the securities because it is likely that CGMI will be the only broker-dealer that is willing to buy your securities prior to maturity. Accordingly, an investor must be prepared to hold the securities until maturity.

▪

The estimated value of the securities on the pricing date, based on CGMI’s proprietary pricing models and our internal funding rate, is less than the issue price. The difference is attributable to certain costs associated with selling, structuring and hedging the securities that are included in the issue price. These costs include (i) the selling concessions paid in connection with the offering of the securities, (ii) hedging and other costs incurred by us and our affiliates in connection with the offering of the securities and (iii) the expected profit (which may be more or less than actual profit) to CGMI or other of our affiliates in connection with hedging our obligations under the securities. These costs adversely affect the economic terms of the securities because, if they were lower, the economic terms of the securities would be more favorable to you. The economic terms of the securities are also likely to be adversely affected by the use of our internal funding rate, rather than our secondary market rate, to price the securities. See “The estimated value of the securities would be lower if it were calculated based on our secondary market rate” below.

▪

The estimated value of the securities was determined for us by our affiliate using proprietary pricing models. CGMI derived the estimated value disclosed on the cover page of this pricing supplement from its proprietary pricing models. In doing so,

it may have made discretionary judgments about the inputs to its models, such as the volatility of the underlying shares, dividend yields on the underlying shares and interest rates. CGMI’s views on these inputs may differ from your or others’ views, and as an underwriter in this offering, CGMI’s interests may conflict with yours. Both the models and the inputs to the models may prove to be wrong and therefore not an accurate reflection of the value of the securities. Moreover, the estimated value of the securities set forth on the cover page of this pricing supplement may differ from the value that we or our affiliates may determine for the securities for other purposes, including for accounting purposes. You should not invest in the securities because of the estimated value of the securities. Instead, you should be willing to hold the securities to maturity irrespective of the initial estimated value.

▪

The estimated value of the securities would be lower if it were calculated based on our secondary market rate. The estimated value of the securities included in this pricing supplement is calculated based on our internal funding rate, which is the rate at which we are willing to borrow funds through the issuance of the securities. Our internal funding rate is generally lower than our secondary market rate, which is the rate that CGMI will use in determining the value of the securities for purposes of any purchases of the securities from you in the secondary market. If the estimated value included in this pricing supplement were based on our secondary market rate, rather than our internal funding rate, it would likely be lower. We determine our internal funding rate based on factors such as the costs associated with the securities, which are generally higher than the costs associated with conventional debt securities, and our liquidity needs and preferences. Our internal funding rate is not the same as the coupon that is payable on the securities.

Because there is not an active market for traded instruments referencing our outstanding debt obligations, CGMI determines our secondary market rate based on the market price of traded instruments referencing the debt obligations of Citigroup Inc., our parent company and the guarantor of all payments due on the securities, but subject to adjustments that CGMI makes in its sole discretion. As a result, our secondary market rate is not a market-determined measure of our creditworthiness, but rather reflects the market’s perception of our parent company’s creditworthiness as adjusted for discretionary factors such as CGMI’s preferences with respect to purchasing the securities prior to maturity.

▪

The estimated value of the securities is not an indication of the price, if any, at which CGMI or any other person may be willing to buy the securities from you in the secondary market. Any such secondary market price will fluctuate over the term of the securities based on the market and other factors described in the next risk factor. Moreover, unlike the estimated value included in this pricing supplement, any value of the securities determined for purposes of a secondary market transaction will be based on our secondary market rate, which will likely result in a lower value for the securities than if our internal funding rate were used. In addition, any secondary market price for the securities will be reduced by a bid-ask spread, which may vary depending on the aggregate stated principal amount of the securities to be purchased in the secondary market transaction, and the expected cost of unwinding related hedging transactions. As a result, it is likely that any secondary market price for the securities will be less than the issue price.

▪

The value of the securities prior to maturity will fluctuate based on many unpredictable factors. The value of your securities prior to maturity will fluctuate based on the prices and volatility of the underlying shares and a number of other factors, including the price and volatility of the stocks included in or held by, as applicable, the underlying shares, the correlation between the underlying shares, dividend yields on the underlying shares, interest rates generally, the time remaining to maturity and our and Citigroup Inc.’s creditworthiness, as reflected in our secondary market rate. Changes in the prices of the underlying shares may not result in a comparable change in the value of your securities. You should understand that the value of your securities at any time prior to maturity may be significantly less than the issue price.

▪

Immediately following issuance, any secondary market bid price provided by CGMI, and the value that will be indicated on any brokerage account statements prepared by CGMI or its affiliates, will reflect a temporary upward adjustment. The amount of this temporary upward adjustment will steadily decline to zero over the temporary adjustment period. See “Valuation of the Securities” in this pricing supplement.

▪

Investing in the securities exposes investors to concentrated risks associated with the energy sector. The stocks included in the index underlying the Energy Select Sector SPDR^®Fund and that are generally tracked by the Energy Select Sector SPDR^®Fund are stocks of companies whose primary business is directly associated with the energy sector, including the following two sub-sectors: (i) oil, gas and consumable fuels and (ii) energy equipment and services. Because the securities are linked to the performance of the underlying shares, an investment in the securities exposes investors to concentrated risks associated with investments in the energy sector.

Energy companies develop and produce crude oil and natural gas and/or provide drilling and other energy resources production and distribution related services. Stock prices for these types of companies are mainly affected by the business, financial and operating conditions of the particular company, as well as changes in prices for oil, gas and other types of fuels, which in turn largely depend on supply and demand for various energy products and services. Some of the factors that may influence supply and demand for energy products and services include: general economic conditions and growth rates; weather conditions; the cost of exploring for, producing and delivering oil and gas; technological advances affecting energy efficiency and energy consumption; the ability of the Organization of Petroleum Exporting Countries (OPEC) to set and maintain production levels of oil; currency fluctuations; inflation; natural disasters; civil unrest, acts of sabotage or terrorism; and other regional or global events. The profitability of energy companies may also be adversely affected by existing and future laws, regulations, government actions and other legal requirements relating to protection of the environment, health and safety matters and others that may increase the costs of conducting their business or may reduce or delay available business opportunities. Increased supply or weak demand for

Citigroup Global Markets Holdings Inc.

energy products and services, as well as various developments leading to higher costs of doing business or missed business opportunities, would adversely impact the performance of companies in the energy sector. The value of the securities may be subject to greater volatility and be more adversely affected by a single economic, political or regulatory occurrence affecting the energy sector or one of the sub-sectors of the energy sector than a different investment linked to securities of a more broadly diversified group of issuers.

▪

The SPDR^® S&P^® Oil & Gas Exploration & Production ETF is subject to concentrated risks associated with the oil and gas exploration and production industry. The stocks included in the index underlying the SPDR^® S&P^® Oil & Gas Exploration & Production ETF and that are generally tracked by the SPDR^® S&P^® Oil & Gas Exploration & Production ETF are stocks of companies whose primary business is associated with the exploration and production of oil and gas. The oil and gas industry is significantly affected by a number of factors that influence worldwide economic conditions and oil prices, such as natural disasters, supply disruptions, geopolitical events and other factors that may offset or magnify each other, including:

employment levels and job growth;

worldwide and domestic supplies of, and demand for, oil and gas;

the cost of exploring for, developing, producing, refining and marketing oil and gas;

consumer confidence;

changes in weather patterns and climatic changes;

the ability of the members of Organization of Petroleum Exporting Countries and other oil and gas producing nations to agree to and maintain production levels;

the price and availability of alternative and competing fuels;

domestic and foreign governmental regulations and taxes;

the worldwide military and political environment, uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities or further acts of terrorism in the United States, or elsewhere; and

general economic conditions worldwide.

These or other factors or the absence of such factors could cause a downturn in the oil and natural gas industries generally or regionally and could cause the value of the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF to decline during the term of the securities.

▪

Changes that affect the underlying shares may affect the value of your securities. The sponsors of the indices underlying the Energy Select Sector SPDR^® Fund and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF may add, delete or substitute the stocks that constitute those indexes or make other methodological changes that could affect the levels of those indexes. In addition, the investment adviser to the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF may change the manner in which the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF operate or its investment objectives at any time. We are not affiliated with any such index sponsors or investment advisors and, accordingly, we have no control over any changes any such index sponsor or investment adviser may make. Such changes could be made at any time and could adversely affect the performance of the underlying shares and the value of and your return on the securities.

▪

Even if the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF pays a dividend that it identifies as special or extraordinary, no adjustment will be required under the securities for that dividend unless it meets the criteria specified in the accompanying product supplement. In general, an adjustment will not be made under the terms of the securities for any cash dividend paid on shares of the Energy Select Sector SPDR^® Fund or shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF unless the amount of the dividend per share, together with any other dividends paid in the same quarter, exceeds the dividend paid per share in the most recent quarter by an amount equal to at least 10% of the closing price of the shares of the Energy Select Sector SPDR^® Fund or the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF, as applicable, on the date of declaration of the dividend. Any dividend will reduce the closing price of the shares of the Energy Select Sector SPDR^® Fund or the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF by the amount of the dividend per share. If the issuer of the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF pays any dividend for which an adjustment is not made under the terms of the securities, holders of the securities will be adversely affected. See “Description of the Securities—Certain Additional Terms for Securities Linked to Company Shares or ETF Shares—Dilution and Reorganization Adjustments—Certain Extraordinary Cash Dividends” in the accompanying product supplement.

▪

An adjustment will not be made for all events that may have a dilutive effect on or otherwise adversely affect the market price of shares of the Energy Select Sector SPDR^® Fund or shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF. For example, we will not make any adjustment for ordinary dividends or extraordinary dividends that do not meet the criteria described above. Moreover, the adjustments we do make may not fully offset the dilutive or adverse effect of the particular event. Investors in the securities may be adversely affected by such an event in a circumstance in which a direct holder of shares of the Energy Select Sector SPDR^® Fund or shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF would not.

▪

The securities may become linked to shares of an ETF other than the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF upon the occurrence of a reorganization event or upon the delisting of the shares of the Energy Select Sector SPDR^® Fund or the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF. For example, if the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF enters into a merger agreement that provides for holders of the shares of the Energy Select Sector SPDR^® Fund or the shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF to receive shares of another entity, the shares of such other entity will

become the applicable underlying shares for all purposes of the securities upon consummation of the merger. Additionally, if the shares of the Energy Select Sector SPDR^® Fund or the shares of SPDR^® S&P^® Oil & Gas Exploration & Production ETF are delisted, or the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF are otherwise terminated, the calculation agent may, in its sole discretion, select shares of another ETF to be the applicable underlying shares. See “Description of the Securities—Certain Additional Terms for Securities Linked to Company Shares or ETF Shares—Dilution and Reorganization Adjustments” and “—Delisting, Liquidation or Termination of an Underlying ETF” in the accompanying product supplement.

▪

The price and performance of shares of the Energy Select Sector SPDR^® Fund and shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF may not completely track the performance of the underlying indices they seek to track or the net asset values per share of the Energy Select Sector SPDR^® Fund and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF. The Energy Select Sector SPDR^® Fund and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF do not fully replicate the underlying indices that they seek to track and may hold securities different from those included in their underlying indices. In addition, the performance of the Energy Select Sector SPDR^® Fund and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF reflect additional transaction costs and fees that are not included in the calculation of their underlying indices. All of these factors may lead to a lack of correlation between the performance of shares of the Energy Select Sector SPDR^® Fund and shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF and their underlying indices. In addition, corporate actions with respect to the equity securities constituting the Energy Select Sector SPDR^® Fund’s or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF’s underlying indices or held by the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF (such as mergers and spin-offs) may impact the variance between the performance of shares of the Energy Select Sector SPDR^® Fund and shares the SPDR^® S&P^® Oil & Gas Exploration & Production ETF and their underlying indices. Finally, because shares of the Energy Select Sector SPDR^® Fund and shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF are traded on NYSE Arca, Inc. and are subject to market supply and investor demand, the market value of the Energy Select Sector SPDR^® Fund and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF may differ from their net asset values per share.

During periods of market volatility, securities underlying the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF and the liquidity of shares of the Energy Select Sector SPDR^® Fund or shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares of the Energy Select Sector SPDR^® Fund or shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF. Further, market volatility may adversely affect, sometimes materially, the price at which market participants are willing to buy and sell shares of the Energy Select Sector SPDR^® Fund or shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF. As a result, under these circumstances, the market value of shares of the Energy Select Sector SPDR^® Fund or shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF may vary substantially from its net asset value per share. For all of the foregoing reasons, the performance of shares of the Energy Select Sector SPDR^® Fund and shares the SPDR^® S&P^® Oil & Gas Exploration & Production ETF might not correlate with the performance of their underlying indices and/or their net asset values per share, which could materially and adversely affect the value of the securities in the secondary market and/or reduce your return on the securities.

▪

Our offering of the securities is not a recommendation of either of the underlying shares. The fact that we are offering the securities does not mean that we believe that investing in an instrument linked to the underlying shares is likely to achieve favorable returns. In fact, as we are part of a global financial institution, our affiliates may have positions (including short positions) in the underlying shares or the stocks held by the ETF or in instruments related to the underlying shares or the stocks held by the ETF, and may publish research or express opinions, that in each case are inconsistent with an investment linked to the underlying shares. These and other activities of our affiliates’ may affect the prices of the underlying shares in a way that has a negative impact on your interests as a holder of the securities.

▪

The prices of the underlying shares may be adversely affected by our or our affiliates’ hedging and other trading activities. We have hedged our obligations under the securities through CGMI or other of our affiliates, who have taken positions directly in the stocks included in the shares of the Energy Select Sector SPDR^® Fund and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF and other financial instruments related to the underlying shares or the stocks held by the ETF and may adjust such positions during the term of the securities. Our affiliates also trade the stocks included in the shares of the Energy Select Sector SPDR^® Fund and shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF and other related financial instruments on a regular basis (taking long or short positions or both), for their accounts, for other accounts under their management or to facilitate transactions on behalf of customers. These activities could affect the prices of the underlying shares in a way that negatively affects the value of the securities. They could also result in substantial returns for us or our affiliates while the value of the securities declines.

We and our affiliates may have economic interests that are adverse to yours as a result of our affiliates’ business activities. Our affiliates may currently or from time to time engage in business with the companies held by the ETF, the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF, including extending loans to, making equity investments in or providing advisory services to such companies or the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF. In the course of this business, we or our affiliates may acquire non-public information which we will not disclose to you. Moreover, if any of our affiliates is or becomes a creditor of any such company, they may exercise any remedies against such company that are available to them without regard to your interests.

▪

The calculation agent, which is an affiliate of ours, will make important determinations with respect to the securities. If certain events occur, such as market disruption events, events with respect to the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF that may require a dilution adjustment or the delisting of the Energy Select Sector SPDR^® Fund or the SPDR^® S&P^® Oil & Gas Exploration & Production ETF, CGMI, as calculation agent, will be required to make discretionary judgments that could significantly affect your return on the securities. In making these judgments, the calculation agent’s interests as an affiliate of ours could be adverse to your interests as a holder of the securities.

▪

The U.S. federal tax consequences of an investment in the securities are unclear. There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the treatment of the securities as described in “United States Federal Tax Considerations” below. If the IRS were successful in asserting an alternative treatment, the tax consequences of ownership and disposition of the securities might be materially and adversely affected. Moreover, as described in the accompanying product supplement under “United States Federal Tax Considerations,” in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. While it is not clear whether the securities would be viewed as similar to the typical prepaid forward contract described in the notice, it is possible that any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, including the character and timing of income or loss recognized by U.S. investors, possibly with retroactive effect. You should read carefully the discussion under “United States Federal Tax Considerations” and “Risk Factors Relating to the Securities” in the accompanying product supplement and “United States Federal Tax Considerations” in this pricing supplement. You should also consult your tax adviser regarding the U.S. federal tax consequences of an investment in the securities, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Non-U.S. investors should note that persons having withholding responsibility in respect of the securities may withhold on any coupon payment paid to a non-U.S. investor, generally at a rate of 30%. To the extent that we have withholding responsibility in respect of the securities, we intend to so withhold.

In addition, Section 871(m) of the Internal Revenue Code of 1986, as amended (the “Code”), imposes a withholding tax of up to 30% on “dividend equivalents” paid or deemed paid to non-U.S. investors in respect of certain financial instruments linked to U.S. equities. In light of Treasury regulations, as modified by an IRS notice, that provide a general exemption for financial instruments issued in 2018 that do not have a “delta” of one, the securities should not be subject to withholding under Section 871(m). However, the IRS could challenge this conclusion.

We will not be required to pay any additional amounts with respect to amounts withheld.

United States Federal Tax Considerations

You should read carefully the discussion under “United States Federal Tax Considerations” and “Risk Factors Relating to the Securities” in the accompanying product supplement and “Summary Risk Factors” in this pricing supplement.

Due to the lack of any controlling legal authority, there is substantial uncertainty regarding the U.S. federal tax consequences of an investment in the securities. In connection with any information reporting requirements we may have in respect of the securities under applicable law, we intend (in the absence of an administrative determination or judicial ruling to the contrary) to treat the securities for U.S. federal income tax purposes as prepaid forward contracts with associated coupon payments that will be treated as gross income to you at the time received or accrued in accordance with your regular method of tax accounting. In the opinion of our counsel, Davis Polk & Wardwell LLP, which is based on current market conditions, this treatment of the securities is reasonable under current law; however, our counsel has advised us that it is unable to conclude affirmatively that this treatment is more likely than not to be upheld, and that alternative treatments are possible.

Assuming this treatment of the securities is respected and subject to the discussion in “United States Federal Tax Considerations” in the accompanying product supplement, the following U.S. federal income tax consequences should result under current law:

Any coupon payments on the securities should be taxable as ordinary income to you at the time received or accrued in accordance with your regular method of accounting for U.S. federal income tax purposes.

Upon a sale or exchange of a security (including retirement at maturity), you should recognize capital gain or loss equal to the difference between the amount realized and your tax basis in the security. For this purpose, the amount realized does not include any coupon paid on retirement and may not include sale proceeds attributable to an accrued coupon, which may be treated as a coupon payment. Such gain or loss should be long-term capital gain or loss if you held the security for more than one year.

We do not plan to request a ruling from the IRS regarding the treatment of the securities, and the IRS or a court might not agree with the treatment described herein. In addition, the U.S. Treasury Department and the IRS have released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts.” While it is not clear whether the securities would be viewed as similar to the typical prepaid forward contract described in the notice, it is possible that any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, including the character and timing of income or loss, possibly with retroactive effect. You should consult your tax adviser regarding possible alternative tax treatments of the securities and potential consequences of the IRS notice.

Withholding Tax on Non-U.S. Holders. Because significant aspects of the tax treatment of the securities are uncertain, persons having withholding responsibility in respect of the securities may withhold on any coupon payment paid to Non-U.S. Holders (as defined in the accompanying product supplement), generally at a rate of 30%. To the extent that we have (or an affiliate of ours has) withholding responsibility in respect of the securities, we intend to so withhold. In order to claim an exemption from, or a reduction in, the 30% withholding, you may need to comply with certification requirements to establish that you are not a U.S. person and are eligible for such an exemption or reduction under an applicable tax treaty. You should consult your tax adviser regarding the tax treatment of the securities, including the possibility of obtaining a refund of any amounts withheld and the certification requirement described above.

Moreover, as discussed under “United States Federal Tax Considerations – Tax Consequences to Non-U.S. Holders – Possible Withholding Under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities (“U.S. Underlying Equities”) or indices that include U.S. Underlying Equities. Section 871(m) generally applies to instruments that substantially replicate the economic performance of one or more U.S. Underlying Equities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, the regulations, as modified by an IRS notice, exempt financial instruments issued in 2018 that do not have a “delta” of one. Based on the terms of the securities and representations provided by us, our counsel is of the opinion that the securities should not be treated as transactions that have a “delta” of one within the meaning of the regulations with respect to any U.S. Underlying Equity and, therefore, should not be Specified Securities subject to withholding tax under Section 871(m).

A determination that the securities are not subject to Section 871(m) is not binding on the IRS, and the IRS may disagree with this treatment. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances. For example, if you enter into other transactions relating to a U.S. Underlying Equity, you could be subject to withholding tax or income tax liability under Section 871(m) even if the securities are not Specified Securities subject to Section 871(m) as a general matter. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

We will not be required to pay any additional amounts with respect to amounts withheld.

You should read the section entitled “United States Federal Tax Considerations” in the accompanying product supplement. The preceding discussion, when read in combination with that section, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of owning and disposing of the securities.

You should also consult your tax adviser regarding all aspects of the U.S. federal income and estate tax consequences of an investment in the securities and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Supplemental Plan of Distribution

CGMI, an affiliate of Citigroup Global Markets Holdings Inc. and the underwriter of the sale of the securities, is acting as principal and will receive an underwriting fee of $37.00 for each $1,000 security sold in this offering. CGMI will pay selected dealers not affiliated with CGMI a fixed selling concession of $37.00 for each $1,000 security they sell. For the avoidance of doubt, the fees and selling concessions described in this pricing supplement will not be rebated if the securities are automatically redeemed prior to maturity.

CGMI is an affiliate of ours. Accordingly, this offering will conform with the requirements addressing conflicts of interest when distributing the securities of an affiliate set forth in Rule 5121 of the Financial Industry Regulatory Authority. Client accounts over which Citigroup Inc. or its subsidiaries have investment discretion will not be permitted to purchase the securities, either directly or indirectly, without the prior written consent of the client.

Secondary market sales of securities typically settle two business days after the date on which the parties agree to the sale. Because the issue date for the securities is more than two business days after the pricing date, investors who wish to sell the securities at any time prior to the second business day preceding the issue date will be required to specify an alternative settlement date for the secondary market sale to prevent a failed settlement. Investors should consult their own investment advisors in this regard.

See “Plan of Distribution; Conflicts of Interest” in the accompanying product supplement and “Plan of Distribution” in each of the accompanying prospectus supplement and prospectus for additional information.

A portion of the net proceeds from the sale of the securities will be used to hedge our obligations under the securities. We have hedged our obligations under the securities through CGMI or other of our affiliates. CGMI or such other of our affiliates may profit from this hedging activity even if the value of the securities declines. This hedging activity could affect the closing prices of either of the underlying shares and, therefore, the value of and your return on the securities. For additional information on the ways in which our counterparties may hedge our obligations under the securities, see “Use of Proceeds and Hedging” in the accompanying prospectus.

Valuation of the Securities

CGMI calculated the estimated value of the securities set forth on the cover page of this pricing supplement based on proprietary pricing models. CGMI’s proprietary pricing models generated an estimated value for the securities by estimating the value of a hypothetical package of financial instruments that would replicate the payout on the securities, which consists of a fixed-income bond (the “bond component”) and one or more derivative instruments underlying the economic terms of the securities (the “derivative component”). CGMI calculated the estimated value of the bond component using a discount rate based on our internal funding rate. CGMI calculated the estimated value of the derivative component based on a proprietary derivative-pricing model, which generated a theoretical price for the instruments that constitute the derivative component based on various inputs, including the factors described under “Summary Risk Factors—The value of the securities prior to maturity will fluctuate based on many unpredictable factors” in this pricing supplement, but not including our or Citigroup Inc.’s creditworthiness. These inputs may be market-observable or may be based on assumptions made by CGMI in its discretionary judgment.

For a period of approximately three months following issuance of the securities, the price, if any, at which CGMI would be willing to buy the securities from investors, and the value that will be indicated for the securities on any brokerage account statements prepared by CGMI or its affiliates (which value CGMI may also publish through one or more financial information vendors), will reflect a temporary upward adjustment from the price or value that would otherwise be determined. This temporary upward adjustment represents a portion of the hedging profit expected to be realized by CGMI or its affiliates over the term of the securities. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the three-month temporary adjustment period. However, CGMI is not obligated to buy the securities from investors at any time. See “Summary Risk Factors—The securities will not be listed on any securities exchange and you may not be able to sell them prior to maturity.”
