Citigroup Global Markets Holdings Inc.

November , 2024 Medium-Term Senior Notes, Series N Pricing Supplement No. 2024-USNCH[ ] Filed Pursuant to Rule 424(b)(2) Registration Statement Nos. 333-270327 and 333-270327-01

Autocallable Securities Linked to an Unequally Weighted Basket of Six Underlyings Due December 1, 2027

▪

The securities offered by this pricing supplement are unsecured debt securities issued by Citigroup Global Markets Holdings Inc. and guaranteed by Citigroup Inc. Unlike conventional debt securities, the securities do not pay interest, do not guarantee the repayment of principal at maturity and are subject to potential automatic early redemption on a periodic basis on the terms described below. Your return on the securities will depend on the performance of an unequally weighted basket composed of the underlyings specified below.

▪

The securities offer the potential for automatic early redemption at a premium following the first valuation date (other than the final valuation date) on which the basket value is greater than or equal to the initial basket value. If the securities are not automatically redeemed prior to maturity, the payment at maturity will depend on the final basket value. In this circumstance, you will be repaid the stated principal amount of your securities at maturity and receive a premium so long as the final basket value is greater than or equal to the initial basket value. However, if the securities are not automatically redeemed prior to maturity and the final basket value is less than the initial basket value, you will lose 1% of the stated principal amount of your securities for every 1% by which the final basket value is less than the initial basket value. You may lose a significant portion, and up to all, of your investment. Investors in the securities must be willing to forgo any dividends with respect to the underlyings. In addition, investors in the securities must be willing to accept full downside exposure to any depreciation of the basket.

▪

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.

Payout Table and Diagram

The table below illustrates how the amount payable per security will be calculated if the basket value on any valuation date is greater than or equal to the initial basket value. The table and diagram below assume that the premium applicable to each valuation date will be set at the minimum value indicated under "Key Terms" above. The actual premium applicable to each valuation date will be determined on the pricing date.

If the first valuation date on which the basket value is greater than or equal to the initial basket value is . . .	. . . then you will receive the following payment per $1,000 security upon automatic early redemption or at maturity, as applicable:
1st valuation date	$1,000 + applicable premium = $1,000 + $105.00 = $1,105.00
2nd valuation date	$1,000 + applicable premium = $1,000 + $210.00 = $1,210.00
Final valuation date	$1,000 + applicable premium = $1,000 + $315.00 = $1,315.00

If, on any valuation date, the basket value is less than the initial basket value, you will not receive the premium indicated above following that valuation date. In order to receive the premium indicated above, the basket value on the applicable valuation date must be greater than or equal to the initial basket value.

The diagram below illustrates the payment at maturity of the securities, assuming the securities have not previously been automatically redeemed, for a range of hypothetical basket returns.

Investors in the securities will not receive any dividends with respect to the underlyings. The diagram and examples below do not show any effect of lost dividend yield over the term of the securities. See "Summary Risk Factors-You will not receive dividends or have any other rights with respect to the underlyings" below.

Hypothetical Examples of the Payment at Maturity

The examples below illustrate how to determine the payment at maturity on the securities, assuming the various hypothetical final basket values indicated below and assuming the securities are not automatically redeemed prior to maturity. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of what the actual payment at maturity on the securities will be. The actual payment at maturity will depend on the actual final basket value.

The examples below are based on the following hypothetical values and do not reflect the actual initial underlying values of the underlyings. For the actual initial underlying value of each underlying, see the cover page of this pricing supplement. We have used these hypothetical values, rather than the actual values, to simplify the calculations and aid understanding of how the securities work. However, you should understand that the actual payment at maturity on the securities will be calculated based on the actual initial underlying value of each underlying, and not these hypothetical values. For ease of analysis, figures below may have been rounded. The examples below assume that the premium applicable to the final valuation date will be set at the minimum value indicated under "Key Terms" above. The actual premium applicable to the final valuation date will be determined on the pricing date.

Underlying	Hypothetical initial underlying value
EURO STOXX 50® Index	100.00
FTSE® 100 Index	100.00
Nikkei 225 Index	100.00
S&P / ASX 200 Index	100.00
Swiss Market Index	100.00
FTSE® China 50 Index	100.00

Example 1-Upside Scenario A: The final basket value is 110.00, resulting in a 10.00% basket return. In this example, the final basket value is greater than the initial basket value.

Underlying	Hypothetical Closing Value on Final Valuation Date	Hypothetical Underlying Return on Final Valuation Date	Weighting	Hypothetical Weighted Underlying Return on Final Valuation Date
EURO STOXX 50® Index	120.00	20.00%	40.00%	8.00%
FTSE® 100 Index	60.00	-40.00%	20.00%	-8.00%
Nikkei 225 Index	125.00	25.00%	20.00%	5.00%
S&P / ASX 200 Index	108.00	8.00%	7.50%	0.60%
Swiss Market Index	132.00	32.00%	7.50%	2.40%
FTSE® China 50 Index	140.00	40.00%	5.00%	2.00%
Sum of the hypothetical weighted underlying returns:	10.00%
Hypothetical final basket value:	100 × (1 + the sum of the hypothetical weighted underlying returns on final valuation date) = 100 × (1 + 10.00%) = 110.00

Payment at maturity per security = $1,000 + the premium applicable to the final valuation date

= $1,000 + $315.00

= $1,315.00

In this scenario, because the basket has appreciated from the initial basket value to the final basket value, you would be repaid the stated principal amount of your securities at maturity plus the premium applicable to the final valuation date.

Example 2-Upside Scenario B: The final basket value is 145.00, resulting in a 45.00% basket return. In this example, the final basket value is greater than the initial basket value.

Underlying	Hypothetical Closing Value on Final Valuation Date	Hypothetical Underlying Return on Final Valuation Date	Weighting	Hypothetical Weighted Underlying Return on Final Valuation Date
EURO STOXX 50® Index	160.00	60.00%	40.00%	24.00%
FTSE® 100 Index	180.00	80.00%	20.00%	16.00%
Nikkei 225 Index	75.00	-25.00%	20.00%	-5.00%
S&P / ASX 200 Index	128.00	28.00%	7.50%	2.10%
Swiss Market Index	172.00	72.00%	7.50%	5.40%
FTSE® China 50 Index	150.00	50.00%	5.00%	2.50%
Sum of the hypothetical weighted underlying returns:	45.00%
Hypothetical final basket value:	100 × (1 + the sum of the hypothetical weighted underlying returns on final valuation date) = 100 × (1 + 45.00%) = 145.00

Payment at maturity per security = $1,000 + the premium applicable to the final valuation date

= $1,000 + $315.00

= $1,315.00

In this scenario, because the basket has appreciated from the initial basket value to the final basket value, you would be repaid the stated principal amount of your securities at maturity plus the premium applicable to the final valuation date. In this scenario, the premium applicable to the final valuation date is less than the basket return and, as a result, an investment in the securities would underperform a hypothetical alternative investment providing 1-to-1 exposure to the appreciation of the basket.

Example 3-Downside Scenario: The final basket value is 50.00, resulting in a -50.00% basket return. In this example, the final basket value is less than the initial basket value.

Underlying	Hypothetical Closing Value on Final Valuation Date	Hypothetical Underlying Return on Final Valuation Date	Weighting	Hypothetical Weighted Underlying Return on Final Valuation Date
EURO STOXX 50® Index	30.00	-70.00%	40.00%	-28.00%
FTSE® 100 Index	115.00	15.00%	20.00%	3.00%
Nikkei 225 Index	40.00	-60.00%	20.00%	-12.00%
S&P / ASX 200 Index	56.00	-44.00%	7.50%	-3.30%
Swiss Market Index	24.00	-76.00%	7.50%	-5.70%
FTSE® China 50 Index	20.00	-80.00%	5.00%	-4.00%
Sum of the hypothetical weighted underlying returns:	-50.00%
Hypothetical final basket value:	100 × (1 + the sum of the hypothetical weighted underlying returns on final valuation date) = 100 × (1 + -50.00%) = 50.00

Payment at maturity per security = $1,000 + ($1,000 × the basket return)

= $1,000 + ($1,000 × -50.00%)

= $1,000 + -$500.00

= $500.00

In this scenario, the basket has depreciated from the initial basket value to the final basket value and the final basket value is less than the initial basket value. As a result, your total return at maturity in this scenario would be negative and would reflect 1-to-1 exposure to the negative performance of the basket.

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 the underlyings. 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-7 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 final basket value. If the final basket value is less than the initial basket value, you will lose 1% of the stated principal amount of the securities for every 1% by which the basket has declined from the initial basket value. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment.

§

Your potential return on the securities is limited. Your potential return on the securities is limited to the applicable premium payable upon automatic early redemption or at maturity, as described on the cover page of this pricing supplement. If the basket value on one of the valuation dates is greater than or equal to the initial basket value, you will be repaid the stated principal amount of your securities and will receive the fixed premium applicable to that valuation date, regardless of how significantly the basket value on that valuation date may exceed the initial basket value. Accordingly, any premium may result in a return on the securities that is significantly less than the return you could have achieved on a direct investment in the underlyings.

§	The securities do not pay interest. You should not invest in the securities if you seek current income during the term of the securities.

§

The securities may be automatically redeemed prior to maturity, limiting the term of the securities. If the basket value on any valuation date (other than the final valuation date) is greater than or equal to the initial basket value, the securities will be automatically redeemed. If the securities are automatically redeemed following any valuation date (other than the final valuation date), they will cease to be outstanding and you will not receive the premium applicable to any later valuation date. 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 basket, but no upside exposure to the basket. You will not participate in any appreciation in the value of the basket over the term of the securities. Consequently, your return on the securities will be limited to the applicable premium payable upon an automatic early redemption or at maturity and may be significantly less than the return on the basket over the term of the securities.

§

You will not receive dividends or have any other rights with respect to the underlyings. You will not receive any dividends with respect to the underlyings. This lost dividend yield may be significant over the term of the securities. The payment scenarios described in this pricing supplement do not show any effect of such lost dividend yield over the term of the securities. In addition, you will not have voting rights or any other rights with respect to the underlyings or the stocks included in the underlyings.

§

The performance of the securities will depend on the basket value solely on the valuation dates, which makes the securities particularly sensitive to volatility in the closing values of the underlyings that constitute the basket on or near the valuation dates. Whether the securities will be automatically redeemed prior to maturity will depend on the basket value solely on the valuation dates (other than the final valuation date), regardless of the basket value on other days during the term of the securities. If the securities are not automatically redeemed prior to maturity, what you receive at maturity will depend solely on the basket value 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 basket value on a limited number of dates, the securities will be particularly sensitive to volatility in the closing values of the underlyings that constitute the basket. You should understand that the closing values of the underlyings 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 anything 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) any selling concessions or other fees 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 underlyings, the correlation between the underlyings, the dividend yields on the underlyings 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 an interest rate 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 closing values of the underlyings, the volatility of and correlation between the closing values of the underlyings, the dividend yields on the underlyings, interest rates generally, the time remaining to maturity and our and Citigroup Inc.'s creditworthiness, as reflected in our secondary market rate, among other factors described under "Risk Factors Relating to the Securities-Risk Factors Relating to All Securities-The value of your securities prior to maturity will fluctuate based on many unpredictable factors" in the accompanying product supplement. Changes in the closing values of the underlyings 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.

§

The underlyings are subject to risks associated with non-U.S. markets, and the FTSE® China 50 Index, in particular, is subject to risks associated with emerging markets. Investments linked to the value of non-U.S. stocks involve risks associated with the securities markets in those countries, including risks of volatility in those markets, governmental intervention in those markets and cross-shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than about U.S. companies that are subject to the reporting requirements of the SEC. Further, non-U.S. companies are generally subject to accounting, auditing and financial reporting standards and requirements and securities trading rules that are different from those applicable to U.S. reporting companies. The prices of securities in foreign markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws. Moreover, the economies in such countries may differ favorably or unfavorably from the economy of the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

With respect to the FTSE^® China 50 Index, stocks issued by companies in emerging markets may be subject to heightened risks, including risks of relatively unstable governments, nationalization of businesses, restrictions on foreign ownership, prohibitions on the repatriation of assets and less protection of property rights. The economies of countries with emerging markets may be based on only a few industries, be highly vulnerable to changes in local or global trade conditions and suffer from extreme and volatile debt burdens or inflation rates. Local securities markets may trade a small number of securities and be unable to respond effectively to increases in trading volume, potentially increasing price volatility.

§

The performance of the underlyings will not be adjusted for changes in currency exchange rates. The EURO STOXX 50® Index is composed of stocks traded in euro, the FTSE® 100 Index is composed of stocks traded in pound sterling, the Nikkei 225 Index is composed of stocks traded in Japanese yen, the S&P/ASX 200 Index is composed of stocks traded in Australian dollars, the Swiss Market Index® is composed of stocks traded in Swiss franc and the FTSE® China 50 Index is composed of stocks traded in Hong Kong dollars. The value of each of these foreign currencies may be subject to a high degree of fluctuation relative to the U.S. dollar. However, the performance of these underlyings and the value of the securities will not be adjusted for exchange rate fluctuations. If the euro, pound sterling, Japanese yen, Australian dollar, Swiss franc and/or Hong Kong dollar appreciates relative to the U.S. dollar over the term of the securities, your return on the securities will underperform an alternative investment that offers exposure to that appreciation in addition to the changes in the values of the underlyings.

§

Recent executive orders may adversely affect the performance of the FTSE® China 50 Index. Pursuant to recent executive orders, U.S. persons are prohibited from engaging in transactions in, or possession of, publicly traded securities of certain companies that are determined to be linked to the People's Republic of China military, intelligence and security apparatus, or securities that are derivative of, or are designed to provide investment exposure to, those securities. If the issuer of any of the equity securities included in the FTSE® China 50 Index is designated as such a prohibited company, the value of that company may be adversely affected, perhaps significantly, which would adversely affect the performance of the FTSE® China 50 Index. In addition, under these circumstances, the sponsor of the FTSE® China 50 Index is expected to remove the equity securities of that company from FTSE® China 50 Index. Any changes to the composition of the FTSE® China 50 Index in response to these executive orders could adversely affect the performance of the FTSE® China 50 Index, and therefore the value of the securities.

§

Changes in the closing values of the underlyings may offset each other. The performances of the underlyings may not be correlated with each other. If one of the underlyings appreciates, the other underlyings may not appreciate as much or may even depreciate. In such event, the appreciation of one of the underlyings may be moderated, wholly offset or more than offset by lesser appreciation or by depreciation in the value of the other underlyings.

§

The underlyings may be highly correlated in decline. The performances of the underlyings may become highly correlated during periods of declining prices. This may occur because of events that have broad effects on markets generally or on the markets that the underlyings track. If the underlyings become correlated in decline, the depreciation of one underlying will not be offset by the performance of the other underlyings and, in fact, each underlying may contribute to an overall decline from the initial basket value to the final basket value.

§

An investment in the securities is not a diversified investment. The fact that the securities are linked to a basket does not mean that the securities represent a diversified investment. First, although the underlyings differ in important respects, they each track the performance of equity markets, and each may perform poorly if there is a global downturn in equity markets. Second, the securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. No amount of diversification that may be represented by the underlyings will offset the risk that we and Citigroup Inc. may default on our obligations.

§

Our offering of the securities is not a recommendation of the basket or the underlyings. The fact that we are offering the securities does not mean that we believe that investing in an instrument linked to the basket or any of the underlyings 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 underlyings or in instruments related to the underlyings, and may publish research or express opinions, that in each case are inconsistent with an investment linked to the underlyings. These and other activities of our affiliates may affect the closing values of the underlyings in a way that negatively affects the value of and your return on the securities.

§

The underlyings are unequally weighted. Accordingly, the performance of an underlying with a higher weighting will influence the performance of the securities to a greater degree than the performance of an underlying with a lower weighting. If an underlying with a higher weighting performs poorly, its poor performance could negate or diminish the effect on the basket return of any positive performance by a lower-weighted underlying.

§

The closing value of an underlying may be adversely affected by our or our affiliates' hedging and other trading activities. We expect to hedge our obligations under the securities through CGMI or other of our affiliates, who may take positions in the underlyings or in financial instruments related to the underlyings and may adjust such positions during the term of the securities. Our affiliates also take positions in the underlyings or in financial instruments related to the underlyings 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 closing values of the underlyings in a way that negatively affects the value of and your return on 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 engage in business activities with a wide range of companies. These activities include extending loans, making and facilitating investments, underwriting securities offerings and providing advisory services. These activities could involve or affect the underlyings in a way that negatively affects the value of and your return on the securities. They could also result in substantial returns for us or our affiliates while the value of the securities declines. In addition, in the course of this business, we or our affiliates may acquire non-public information, which will not be disclosed to you.

§

The calculation agent, which is an affiliate of ours, will make important determinations with respect to the securities. If certain events occur during the term of the securities, such as market disruption events and other events with respect to an underlying, 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. See "Risk Factors Relating to the Securities-Risk Factors Relating to All Securities-The calculation agent, which is an affiliate of ours, will make important determinations with respect to the securities" in the accompanying product supplement.

§

Changes that affect the underlyings may affect the value of your securities. The sponsors of the underlyings may at any time make methodological changes or other changes in the manner in which they operate that could affect the values of the underlyings. We are not affiliated with any such underlying sponsor and, accordingly, we have no control over any changes any such sponsor may make. Such changes could adversely affect the performance of the underlyings and the value of and your return on 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 prepaid forward contracts. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the securities, possibly retroactively.

If you are a non-U.S. investor, you should review the discussion of withholding tax issues in "United States Federal Tax Considerations-Non-U.S. Holders" below.

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.

Hypothetical Historical Information About the Basket

Because the basket exists solely for purposes of these securities, historical information on the performance of the basket does not exist for dates prior to the pricing date for these securities. The graph below sets forth the hypothetical historical daily values of the basket for the period from January 6, 2014 to November 6, 2024, assuming that the basket was created on January 6, 2014 with the same underlyings and corresponding weights in the basket and with a value of 100 on that date. The hypothetical performance of the basket is based on the actual closing values of the underlyings on the applicable dates. We obtained these closing values from Bloomberg L.P., without independent verification. Any historical trend in the value of the basket during the period shown below is not an indication of the performance of the basket during the term of the securities.

Information About the Nikkei 225 Index

The Nikkei 225 Index is a stock index that measures the composite price performance of selected Japanese stocks. The Nikkei 225 Index is currently based on 225 underlying stocks trading on the Tokyo Stock Exchange representing a broad cross-section of Japanese industries. Non-ordinary shares, such as shares of ETFs, REITs, preferred stock or other preferred securities or tracking stocks, are excluded from the Nikkei 225 Index. It is calculated and maintained by Nikkei Inc.

Please refer to the section "Equity Index Descriptions-The Nikkei 225 Index" in the accompanying underlying supplement, as supplemented by the following updated information.

Effective October 2022, if the weight of any Nikkei Underlying Stock exceeds a certain threshold (the "weight cap threshold") on the base date of a periodic review, a capping ratio will be applied to decrease the weight of that Nikkei Underlying Stock. The weight cap threshold for any Nikkei Underlying Stock is (i) 12% as of the October 2022 periodic review, (ii) 11% as of the October 2023 periodic review and (iii) 10% as of the October 2024 periodic review. For any Nikkei Underlying Stock to which a capping ratio is applied, the price of that Nikkei Underlying Stock is adjusted by a capped price adjustment factor ("CPAF") equal to (i) the capping ratio multiplied by (ii) the PAF (as defined under "Indices-The Nikkei 225 Index-Calculation of the Nikkei 225 Index" in the accompanying underlying supplement).

If, on the base date of a periodic review, the weight of any Nikkei Underlying Stock exceeds the weight cap threshold and a capping ratio does not already apply to that Nikkei Underlying Stock, a capping ratio of 0.9 is applied on the effective date of the periodic review. If a capping ratio already applies to any Nikkei Underlying Stock, the capping ratio will be decreased in increments of 0.1 on the effective date of the periodic review until there is a change in the CPAF. If, on the base date of a periodic change, the weight of a Nikkei Underlying Stock to which a capping ratio is applied is below 5%, the capping ratio will be increased in increments of 0.1 on the effective date of the periodic review until there is a change in the CPAF; however, the capping ratio will be canceled if it increases to 1.0. When a Nikkei Underlying Stock to which a capping ratio is applied effects a large-scale stock split or reverse split and the PAF is adjusted by the ratio of the split or reverse split, the capping ratio may be revised as necessary to ensure that the new CPAF does not change the weight of that Nikkei Underlying Stock.

In addition, as of October 2022, the Nikkei Underlying Stocks are reviewed semiannually with base dates at the end of January and July, and results of each review are applied on the first trading day in April and October, respectively.

We have derived all information regarding the Nikkei 225 Index from publicly available information and have not independently verified any information regarding the Nikkei 225 Index.

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.

In the opinion of our counsel, Davis Polk & Wardwell LLP, a security should be treated as a prepaid forward contract for U.S. federal income tax purposes. By purchasing a security, you agree (in the absence of an administrative determination or judicial ruling to the contrary) to this treatment. There is uncertainty regarding this treatment, and the IRS or a court might not agree with it. Moreover, our counsel's opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date.

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:

·	You should not recognize taxable income over the term of the securities prior to maturity, other than pursuant to a sale or exchange.

·

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. 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. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of "prepaid forward contracts" and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, 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, possibly with retroactive effect. You should consult your tax adviser regarding possible alternative tax treatments of the securities and potential changes in applicable law.

Non-U.S. Holders. Subject to the discussions below and in "United States Federal Tax Considerations" in the accompanying product supplement, if you are a Non-U.S. Holder (as defined in the accompanying product supplement) of the securities, you generally should not be subject to U.S. federal withholding or income tax in respect of any amount paid to you with respect to the securities, provided that (i) income in respect of the securities is not effectively connected with your conduct of a trade or business in the United States, and (ii) you comply with the applicable certification requirements.

As discussed under "United States Federal Tax Considerations-Tax Consequences to Non-U.S. Holders" 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. However, the regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2027 that do not have a "delta" of one. Based on the terms of the securities and representations provided by us as of the date of this preliminary pricing supplement, 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 subject to withholding tax under Section 871(m). However, the final determination regarding the treatment of the securities under Section 871(m) will be made as of the pricing date for the securities, and it is possible that the securities will be subject to withholding tax under Section 871(m) based on the circumstances as of that date.

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, including your other transactions. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

If withholding tax applies 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 up to $22.50 for each security sold in this offering. The actual underwriting fee will be equal to the selling concession provided to selected dealers, as described in this paragraph. From this underwriting fee, CGMI will pay selected dealers not affiliated with CGMI a variable selling concession of up to $22.50 for each security they sell. For the avoidance of doubt, any fees or selling concessions described in this pricing supplement will not be rebated if the securities are automatically redeemed prior to maturity.

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.

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.

The estimated value of the securities is a function of the terms of the securities and the inputs to CGMI's proprietary pricing models. As of the date of this preliminary pricing supplement, it is uncertain what the estimated value of the securities will be on the pricing date because certain terms of the securities have not yet been fixed and because it is uncertain what the values of the inputs to CGMI's proprietary pricing models will be on the pricing date.

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."

Annex A

Description of the FTSE^® China 50 Index

All information contained in this pricing supplement regarding the FTSE^® China 50 Index (the "XIN0I"), including, without limitation, its make-up, method of calculation and changes in its components, has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, FTSE Russell ("FTSE"). The XIN0I is calculated, maintained and published by FTSE. FTSE has no obligation to continue to publish, and may discontinue publication of, the XIN0I.

The XIN0I is designed to represent the performance of the Chinese companies that are listed on the Stock Exchange of Hong Kong Ltd ("HKSE"). The XIN0I is reported by Bloomberg L.P. under the ticker symbol "XIN0I."

Composition of the XIN0I

The XIN0I is currently based on the 50 largest and most liquid Chinese stocks (called "H" shares, "Red Chip" shares and "P Chip" shares), listed and trading on HKSE. "H" shares are securities of companies incorporated in the People's Republic of China and traded on the HKSE. "Red Chip" shares are securities of companies incorporated outside of the People's Republic of China that trade on HKSE and that which are substantially owned directly or indirectly by Mainland Chinese state entities with the majority of their revenue or assets derived from Mainland China. "P Chip" shares are securities of companies (other than a Red Chip company) incorporated outside of the People's Republic of China and traded on HKSE, but are controlled by Mainland Chinese companies and individuals, with the establishment and origins of the companies in Mainland China and with a majority of their revenue or assets derived from Mainland China.

Eligibility

Currently, only H shares, P Chip shares and Red Chip shares are eligible for inclusion in the XIN0I. Each constituent must also be a constituent of the FTSE All-World Index, a market-capitalization weighted index representing the performance of large- and mid-capitalization developed and emerging markets stocks covering 90-95% of the investable market capitalization globally. Non-constituent P Chip shares whose associated "N" shares are already included in the FTSE All-World Index will be eligible for inclusion in the XIN0I at the next quarterly review after a minimum 3-month trading period, subject to satisfying all other FTSE All-World Index eligibility criteria. "N" shares are securities of companies incorporated inside or outside of the People's Republic of China and traded on the New York Stock Exchange or The Nasdaq Stock Market, but are controlled by Mainland Chinese companies and individuals, with a majority of their revenue or assets derived from Mainland China.

The following are considered ineligible for inclusion in the XIN0I:

·	Companies whose business is that of holding equity and other investments (e.g., investment trusts); and

·	limited liability partnerships (LLP), limited partnerships (LP), master limited partnerships (MLP), limited liability companies (LLC) and business development companies (BDC).

Where a stapled unit comprises an eligible security and a non-eligible security (such as non-equity or an investment trust structure), the unit will not be eligible for inclusion.

Screens Applied to Eligible Securities

Securities are screened based on investability, liquidity and trading history according to the following criteria:

Investability. Constituents of the XIN0I are adjusted for free float and foreign ownership limits. Free float is calculated using available published information rounded to 12 decimal places. Companies with a free float of 5% or below are excluded from the XIN0I. The restrictions placed on the equity holdings of foreigners in a company where these have been imposed by a government, regulatory authority or the company's constitution are also considered. In addition, FTSE considers company's "foreign headroom," defined as the percentage of shares available to foreign investors as a proportion of the company's foreign ownership limit ("FOL"), i.e., (FOL - foreign holdings)/FOL.

Liquidity. Each security will be tested for liquidity semi-annually in March and September by calculation of its monthly median of daily trading volume as part of the FTSE All-World Index review. When calculating the median of daily trading volume of any security for a particular month, a minimum of 5 trading days in that month must exist, otherwise the month will be excluded from the test. For each month, the daily trading volume for each security is calculated as a percentage of the shares in issue for that day adjusted by the free float at the review cut-off date. These daily values are then ranked in descending order and the median is taken by selecting the value for the middle ranking day if there is an odd number of days and the mean of the middle two if there is an even number of days. Daily totals with zero trades are included in the ranking; therefore a security that fails to trade for more than half of the days in a month will have a zero median trading volume for that month. Any period of suspension will not be included in the test. The liquidity test will be applied on a pro-rata basis where the testing period is less than 12 months.

Trading Screen. Existing and non-constituent securities, which have not traded on 60 or more trading days during the past year (up to and including the review cut-off date), will not be eligible for index inclusion. Regular/ad-hoc market holidays and unscheduled market closures will not count towards the total; otherwise, the reason(s) for a security's non-trading will not be considered. All standard trading days will be incorporated within the calculation (Friday and Sundays as appropriate). Ad-hoc non-standard trading days will not be incorporated within the calculation. If a security does not have a full year of trading, the 60 day period will be pro-rated according to the number of available trading days passed since its listing. Where a pro-rata calculation is necessary, the number of available trading days on the underlying market during the previous year up to and including the review cut-off date will be used as the basis of the calculation. A security that has been removed from the XIN0I as a result of this screen will only be re-considered for inclusion after a period of 12 months from its deletion. For the purposes of index eligibility, it will be treated as a new issue.

The XIN0I is subject to the oversight of an advisory committee, the "FTSE Russell Asia Pacific Regional Equity Advisory Committee." The FTSE Russell Asia Pacific Regional Equity Advisory Committee is responsible for undertaking the periodic review of the XIN0I ground rules and for considering changes of the ground rules.

Calculation of the XIN0I

The XIN0I is calculated by FTSE using a free float index calculation methodology. The XIN0I is calculated using the following formula:

where "N" is the number of securities in the XIN0I, "p_i" is the latest trade price of the component security "i," "e_i" is the exchange rate required to convert the security's home currency into the XIN0I's base currency, "s_i" is the number of shares of the security in issue, "f" is the free float factor published by FTSE, to be applied to such security to allow amendments to its weighting, "c_i" is the capping factor published by FTSE at the most recent quarterly review of the XIN0I, and "d" is the divisor, a figure that represents the total issued share capital of the XIN0I at the base date, which may be adjusted to allow for changes in the issued share capital of individual securities without distorting the XIN0I. The capping factor serves to limit the weight of any individual company to no more than 9% of the XIN0I and to limit the aggregate weight of all companies that have a weight greater than 4.5% to no more than 38% of the XIN0I.

The XIN0I uses actual trade prices for securities with local stock exchange quotations and Reuters real-time spot currency rates for its calculations. FTSE excludes from free floating shares: (i) shares held by public companies or by non-listed subsidiaries of public companies; (ii) shares held by directors, senior executives and managers of the company and/or their families, direct relations or affiliated companies; (iii) shares held within employee share plans; (iv) government holdings; (v) shares subject to foreign ownership limits; (vi) shares held by strategic investors; (vii) shares subject to lock-in clauses (for the duration of the lock-up); (viii) shares that are subject to on-going contractual agreements (such as swaps) where they would ordinarily be treated as restricted; (ix) shares that are non-negotiable which are held by companies that have not converted these shares following the A Share reform and (x) non-tradable A Shares subject to a lock-in (until the lock-in expires and the shares are freely tradable on the exchange).

Free float is calculated using available published information rounded up to 12 decimal places. Companies with a free float of 5% or below are excluded from the XIN0I. In June, a constituent's free float will be updated regardless of size. No buffers are applied.

Foreign ownership limits, if any, are applied after calculating the free float restriction. If the foreign ownership limit is more restrictive than the free float restriction, the precise foreign ownership limit is applied. If the foreign ownership limit is less restrictive or equal to the free float restriction, the free float restriction is applied.

The XIN0I is periodically reviewed for changes in free float. These reviews coincide with the quarterly reviews undertaken of the XIN0I. The constituents will be reviewed using data from the close of business on the Monday following the third Friday in February, May, August and November. Where there is a market holiday in either China or Hong Kong on the Monday following the third Friday, the close of business on the last trading day prior to the Monday after the third Friday, where both markets are open, will be used. Implementation of any changes takes place at the close of trading on the third Friday in March, June, September and December. A stock's free float is also reviewed and adjusted if necessary following certain corporate events. If the corporate event includes a corporate action which affects the XIN0I, any change in free float is implemented at the same time as the corporate action. If there is no corporate action, the change in free float is applied as soon as practicable after the corporate event.
