---

■ Linked to the iShares<sup>®</sup> Bitcoin Trust ETF (the "underlying")

■ Unlike ordinary debt securities, the securities do not pay interest or repay a fixed amount of principal at maturity and are subject to potential automatic early redemption upon the terms described below. Whether the securities are automatically called for a fixed call premium or, if not automatically called, the maturity payment amount, will depend, in each case, on the performance of the underlying on the applicable calculation day.

■ **Automatic Call.** If the closing value of the underlying on the call date is greater than or equal to the starting value, the securities will be automatically called for redemption for an amount in cash equal to the stated principal amount *plus* the call premium of at least 31.45% of the stated principal amount (to be determined on the pricing date)

■ **Maturity Payment Amount.** If the securities are not automatically called for redemption, you will receive a maturity payment amount that could be greater than, equal to or less than the stated principal amount, depending on the ending value of the underlying as follows:

■ If the ending value is greater than the starting value, you will receive the stated principal amount *plus* a positive return equal to 150% of the percentage increase in the value of the underlying from the starting value

■ If the ending value is less than or equal to the starting value, but greater than or equal to the threshold value, you will be repaid the stated principal amount *plus* a positive return equal to the absolute value of the percentage decline in the value of the underlying from the starting value to the ending value, which will effectively be capped at a positive return of 25%

■ If the ending value is less than the threshold value, you will lose a significant portion, and possibly all, of the stated principal amount of your securities

■ The threshold value for the underlying is equal to 75% of the starting value

■ Investors may lose up to 100% of the stated principal amount

■ Investors should be knowledgeable about the risks associated with cryptocurrencies and digital assets because the underlying seeks to reflect generally the performance of the price of bitcoin and therefore the securities involve the significant risks of investments tracking cryptocurrencies. **Bitcoin has historically exhibited high price volatility relative to more traditional asset classes and has experienced extreme volatility in recent periods and may continue to do so.**

■ If the securities are automatically called, the positive return on the securities will be limited to the call premium, and you will not participate in any appreciation of the underlying beyond the call premium, which may be significant. If the securities are automatically called, you will no longer have the opportunity to participate in any appreciation of the underlying at the participation rate

■ All payments on the securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.; if Citigroup Global Markets Holdings Inc. and Citigroup Inc. default on their obligations, you could lose some or all of your investment

■ No periodic interest payments

■ The securities are subject to redemption at our option if a special early redemption event occurs as described under "Terms of the Securities—Special Early Redemption Right" and "Summary Risk Factors—If A Special Early Redemption Event Occurs, We May Redeem The Securities Early For An Amount That May Result In A Significant Loss On Your Investment" in this pricing supplement

■ The securities will not be listed on any securities exchange and, accordingly, may have limited or no liquidity. You should not invest in the securities unless you are willing to hold them to maturity.

**The securities have complex features and investing in the securities involves risks not associated with an investment in conventional debt securities. See "Summary Risk Factors" beginning on page PS-7 and "Risk Factors" beginning on page PS-5 of the accompanying product supplement and beginning on page S-1 of the accompanying prospectus supplement.** 

**Neither the Securities and Exchange Commission (the "SEC") nor any state securities commission has approved or disapproved of the securities or determined that this pricing supplement or the accompanying product supplement, prospectus supplement and prospectus are truthful or complete. Any representation to the contrary is a criminal offense.**

**The securities are unsecured debt obligations issued by Citigroup Global Markets Holdings Inc. and guaranteed by Citigroup Inc. All payments due on the securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. None of Wells Fargo Securities, LLC ("Wells Fargo") or any of its affiliates will have any liability to the purchasers of the securities in the event Citigroup Global Markets Holdings Inc. defaults on its obligations under the securities and Citigroup Inc. defaults on its guarantee obligations. The securities are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, nor are they obligations of, or guaranteed by, a bank.**

| | **Per Security** | **Total** |
| Public Offering Price<sup>(1)</sup> | $1000.00 | $|

(1) Citigroup Global Markets Holdings Inc. currently expects that the estimated value of the securities on the pricing date will be at least $903.50 per security, which will be less than the public offering price. The estimated value of the securities is based on Citigroup Global Markets Inc.'s ("CGMI") proprietary pricing models and our internal funding rate. It is not an indication of actual profit to CGMI or other of our affiliates, nor is it an indication of the price, if any, at which any person may be willing to buy the securities from you at any time after issuance. See "Valuation of the Securities" in this pricing supplement.

(2) CGMI, an affiliate of Citigroup Global Markets Holdings Inc., as the lead agent for the offering, expects to sell the securities to Wells Fargo, as agent. Wells Fargo will receive an underwriting discount and commission of up to 2.325% ($23.25) for each security it sells. Wells Fargo may pay selected dealers, which may include Wells Fargo Advisors ("WFA") (the trade name of the retail brokerage business of its affiliates, Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC), a fixed selling commission of 1.75% ($17.50) for each security they sell. In addition to the selling commission allowed to WFA, Wells Fargo may pay $0.75 per security of the underwriting discount and commission to WFA as a distribution expense fee for each security sold by WFA. The total underwriting discount and commission and proceeds to Citigroup Global Markets Holdings Inc. shown above give effect to the actual underwriting discount and commission provided for the sale of the securities. See "Supplemental Plan of Distribution" below and "Use of Proceeds and Hedging" in the accompanying prospectus for further information regarding how we have hedged our obligations under the securities. In addition, CGMI will pay to one or more electronic platform providers a fee of up to $0.60 for each security sold in this offering where related selected dealers and/or custodians implement or utilize such providers.

(3) In respect of certain securities sold in this offering, CGMI may pay a fee of up to $1.00 per security to selected securities dealers in consideration for marketing and other services in connection with the distribution of the securities to other securities dealers.

In determining the special early redemption amount, the calculation agent may take into account proprietary pricing models and may make adjustments to those models or inputs to those models in good faith and in a commercially reasonable manner. The calculation agent may also take into account other facts, whether or not unique to us or our affiliates, in determining the special early redemption amount so long as it is in good faith and commercially reasonable. The special early redemption amount may result in a significant loss on your securities. See "Summary Risk Factors—If A Special Early Redemption Event Occurs, We May Redeem The Securities Early For An Amount That May Result In A Significant Loss On Your Investment" in this pricing supplement.<br>The "<u>special early redemption valuation date</u>" is the special early redemption notice date. |

**Investor Considerations**

**The securities are not appropriate for all investors. The securities may be an appropriate investment for investors who:** 

&nbsp;&nbsp;&nbsp;&nbsp;· seek the potential for a fixed return if the underlying has appreciated at all as of the call date in lieu of full participation in
any potential appreciation of the underlying;

&nbsp;&nbsp;&nbsp;&nbsp;· if the securities are not automatically called for redemption prior to maturity, seek leveraged exposure
to the positive performance of the underlying if the ending value is greater than the starting value;

&nbsp;&nbsp;&nbsp;&nbsp;· if the securities are not automatically called for redemption prior to maturity, understand that any positive
return based on the depreciation of the underlying will be limited to 25%, and that any depreciation of the underlying from the starting
value to the ending value of more than 25% will result in a loss, rather than a positive return, on the securities;

&nbsp;&nbsp;&nbsp;&nbsp;· if the securities are not automatically called for redemption prior to maturity, understand that if the
ending value is less than the threshold value, they will be fully exposed to the decline in the underlying from the starting value and
will receive significantly less than the stated principal amount, and possibly nothing, at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;· are knowledgeable about the significant risks associated with cryptocurrencies and digital assets and
can accept those risks;

&nbsp;&nbsp;&nbsp;&nbsp;· understand that the term of the securities may be limited by the automatic call and special early redemption features of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;· understand that, if a special early redemption event occurs, the securities may be redeemed early for an amount that may result in
a significant loss on their investment;

&nbsp;&nbsp;&nbsp;&nbsp;· are willing to forgo interest payments on the securities; and

&nbsp;&nbsp;&nbsp;&nbsp;· are willing to hold the securities to maturity.

**The securities may not be an appropriate investment for investors who:** 

&nbsp;&nbsp;&nbsp;&nbsp;· seek a liquid investment or are unable or unwilling to hold the securities to maturity;

&nbsp;&nbsp;&nbsp;&nbsp;· seek a security with a fixed term;

&nbsp;&nbsp;&nbsp;&nbsp;· are unwilling to accept the risk that, if the securities are not automatically called for redemption prior
to maturity, the ending value may be less than the threshold value;

&nbsp;&nbsp;&nbsp;&nbsp;· are not knowledgeable about the significant risks associated with cryptocurrencies and digital assets
or are unwilling or unable to accept those risks;

&nbsp;&nbsp;&nbsp;&nbsp;· seek full return of the stated principal amount of the securities at maturity or upon special early redemption;

&nbsp;&nbsp;&nbsp;&nbsp;· seek current income;

&nbsp;&nbsp;&nbsp;&nbsp;· are unwilling to purchase securities with the estimated value set forth on the cover page;

&nbsp;&nbsp;&nbsp;&nbsp;· are unwilling to accept the risk of exposure to the underlying;

&nbsp;&nbsp;&nbsp;&nbsp;· seek exposure to the underlying but are unwilling to accept the risk/return trade-offs inherent in the
terms of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;· are unwilling to accept the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.;
or

&nbsp;&nbsp;&nbsp;&nbsp;· prefer the lower risk of fixed income investments with comparable maturities issued by companies with
comparable credit ratings.

**The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the "Summary Risk Factors" herein and the "Risk Factors" in the accompanying product supplement for risks related to an investment in the securities. For more information about the underlying, please see the information provided below.**

**Determining Timing and Amount of Payment on the Securities**

**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 underlying. Accordingly, the securities are appropriate 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 appropriateness 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" beginning on page PS-5 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 A Significant Portion, And Possibly All, Of Your Investment.**

Unlike conventional debt securities, the securities do not repay a fixed amount of principal at maturity. Instead, if the securities are not automatically called for redemption prior to maturity, your maturity payment amount will depend on the performance of the underlying. If the securities are not automatically called for redemption prior to maturity and the ending value is less than the threshold value, you will lose 1% of the stated principal amount of the securities for every 1% by which the underlying has declined from the starting value. There is no minimum maturity payment amount on the securities, and you may lose up to all of your investment.

**The Securities Do Not Pay Interest.**

Unlike conventional debt securities, the securities do not pay interest. You should not invest in the securities if you seek current income during the term of the securities.

**If The Securities Are Not Automatically Called For Redemption Prior To Maturity, Your Potential Return On The Securities From Depreciation Of The Underlying Is Limited.** 

If the securities are not automatically called for redemption prior to maturity, the return potential of the securities in the event that the ending value is less than the starting value is limited by the threshold value. Any decline in the ending value below the threshold value will result in a loss, rather than a positive return, on the securities.

**If The Securities Are Automatically Called For Redemption Prior To Maturity, Your Potential Return On The Securities Is Limited.**

If the securities are automatically called for redemption prior to maturity, your potential return on the securities is limited to the call premium payable upon automatic call. If the closing value of the underlying on the call date is greater than or equal to the starting value, you will be repaid the stated principal amount of your securities and will receive the fixed call premium, regardless of how significantly the closing value of the underlying on that call date may exceed the starting value. Accordingly, the call 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 underlying. If the securities are automatically called for redemption, you will no longer have the opportunity to participate in any appreciation of the underlying at the participation rate.

**The Securities May Be Automatically Called For Redemption Prior To Maturity, Limiting The Term Of The Securities.**

If the closing value of the underlying on the call date is greater than or equal to the starting value, the securities will be automatically called for redemption. If the securities are automatically called for redemption following the call date, they will cease to be outstanding and you may not be able to reinvest your funds in another investment that provides a similar yield with a similar level of risk.

**If A Special Early Redemption Event Occurs, We May Redeem The Securities Early For An Amount That May Result In A Significant Loss On Your Investment.**

See "Terms of the Securities—Special Early Redemption Right" above in this pricing supplement for information about the events that may constitute a special early redemption event. If a special early redemption event occurs, we may redeem the securities prior to the maturity date for an amount equal to the special early redemption amount determined as of the special early redemption valuation

date. The special early redemption amount will be determined in a manner based upon (but not necessarily identical to) CGMI's then contemporaneous practices for determining secondary market bid prices for the securities and similar instruments, subject to the exceptions and more detailed provisions set forth under "Terms of the Securities—Special Early Redemption Right" above in this pricing supplement. As discussed below, any secondary market bid price is likely to be less than the issue price and, absent favorable changes in market conditions and other relevant factors, is also likely to be less than the estimated value of the securities set forth on the cover page of this pricing supplement. Accordingly, if a special early redemption event occurs, there is a significant likelihood that the special early redemption amount you receive will result in a loss on your investment in the securities. Moreover, in determining the special early redemption amount, the calculation agent will take into account the relevant event that has occurred, and that event may have a significant adverse effect on the market for the underlying or cryptocurrency markets generally, resulting in a special early redemption amount that is significantly less than the amount you paid for your securities. You may lose up to all of your investment.

The special early redemption amount may be significantly less than the amount you would have received had we not elected to redeem the securities and had you been able instead to hold them to maturity. For example, the special early redemption amount may be determined during a market disruption that has a significant adverse effect on the special early redemption amount. That market disruption may be resolved by the time of the originally scheduled maturity date and, had your payment on the securities been determined on the scheduled final calculation day rather than on the special early redemption valuation date, you might have achieved a significantly better return.

**The Calculation Agent May Make Discretionary Determinations In Connection With A Special Early Redemption Event And The Special Early Redemption Amount That Could Adversely Affect Your Return Upon Special Early Redemption.** 

The calculation agent will be required to exercise discretion in determining whether a special early redemption event has occurred. If the calculation agent determines that a special early redemption event has occurred and as a result we elect to redeem the securities upon the occurrence of such special early redemption event, you may incur a significant loss on your investment in the securities.

In addition, the calculation agent has broad discretion to determine the special early redemption amount, including the ability to make adjustments to proprietary pricing models and inputs to those models in good faith and in a commercially reasonable manner. The fact that the calculation agent is our affiliate may cause it to have interests that are adverse to yours as a holder of the securities. Under the terms of the securities, the calculation agent has the authority to make determinations that may protect our economic interests while resulting in a significant loss to you on your investment in the securities.

**You Will Not Have Any Rights With Respect To The Underlying.** 

You will not have voting rights or any other rights with respect to the underlying. If any change to the underlying is proposed, such as an amendment to the underlying's organizational documents, you will not have the right to vote on such change. Any such change may adversely affect the market value of the underlying.

**The Performance Of The Securities Will Depend On The Closing Values Of The Underlying Solely On The Calculation Days, Which Makes The Securities Particularly Sensitive To Volatility In The Closing Values Of The Underlying On Or Near The Calculation Days.**

Whether the securities will be automatically called for redemption will depend on the closing value of the underlying solely on the call date, regardless of the closing value of the underlying on other days during the term of the securities. If the securities are not automatically called for redemption, what you receive at maturity will depend solely on the ending value, and not the closing value of the underlying on any other day during the term of the securities. Because the performance of the securities depends on the closing values of the underlying on a limited number of dates, the securities will be particularly sensitive to volatility in the closing values of the underlying. You should understand that the closing value of the underlying has 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. We have been advised that Wells Fargo currently intends to make a secondary market in relation to the securities. However, Wells Fargo may suspend or terminate making a market without notice, at any time and for any reason. If Wells Fargo suspends or terminates making a market, there may be no secondary market at all for the securities because it is likely that Wells Fargo 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 Public Offering Price.** 

The difference is attributable to certain costs associated with selling, structuring and hedging the securities that are included in the public offering 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 and/or Wells Fargo or its 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 Wells Fargo's Determination Of The Secondary Market Rate With Respect To Us" 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 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 Wells Fargo's Determination Of The Secondary Market Rate With Respect To Us.** 

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. We expect that our internal funding rate is generally lower than Wells Fargo's determination of the secondary market rate with respect to us, which is the rate that we expect Wells Fargo 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 Wells Fargo's determination of the secondary market rate with respect to us, 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, Wells Fargo may determine the secondary market rate with respect to us for purposes of any purchase of the securities from you in the secondary market 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 Wells Fargo may deem appropriate.

**The Estimated Value Of The Securities Is Not An Indication Of The Price, If Any, At Which Any 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, we expect that any value of the securities determined for purposes of a secondary market transaction will be based on Wells Fargo's determination of the secondary market rate with respect to us, which will likely result in a lower value for the securities than if our internal funding rate were used. In addition, we expect that 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 may be reduced by 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 public offering 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 value of the underlying, the volatility of the closing value of the underlying, 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—General 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 value of the underlying 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 public offering price.

**We Have Been Advised That, Immediately Following Issuance, Any Secondary Market Bid Price Provided By Wells Fargo, And The Value That Will Be Indicated On Any Brokerage Account Statements Prepared By Wells Fargo 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 Securities Are Subject To Risks Associated With Bitcoin And Digital Assets.** 

The investment objective of the underlying is to reflect generally the performance of the price of bitcoin, less the underlying's expenses. Bitcoin is a digital asset, and use of bitcoin in the retail and commercial marketplace is relatively limited. Bitcoin generally operates without central authority or banks and is not backed by any government or organized governing body. Digital assets such as bitcoin represent new, novel and rapidly evolving products, and their value is influenced by a wide variety of factors that are uncertain and difficult to evaluate. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility in recent periods and may continue to do so. Digital asset markets in the United States exist in a state of regulatory uncertainty and the exchanges on which bitcoin trades globally, including in the United States, are relatively new and, in most cases, largely unregulated. Legislative or regulatory developments could significantly affect the value of bitcoin, as could competition from other digital assets. Political or economic crises may motivate large-scale sales of bitcoin, resulting in a reduction in the price of bitcoin. The value of bitcoin could be adversely affected by the actions of bitcoin miners and changes in the block rewards and transaction fees miners earn. Bitcoin is susceptible to theft, loss and fraud. The bitcoin network, bitcoin custodians and trading platforms are subject to risks relating to operational problems, technical glitches, internet disruptions, shutdowns, hackers and malware, all of which may also affect the price of bitcoin. Over the past several years, some digital asset platforms have been closed, been subject to criminal and civil litigation and have entered into bankruptcy proceedings due to fraud and manipulative activity, business failure and/or security breaches. Negative perception, a lack of stability and standardized regulation in the digital asset markets and/or the closure or temporary shutdown of digital asset trading platforms due to fraud, business failure, security breaches or government mandated regulation, and associated losses by customers, may reduce confidence in digital asset networks and result in greater volatility in the prices of digital assets, including bitcoin. These and other factors could have an adverse effect on the price of bitcoin and, therefore, the value of the securities.

**Investments Linked To Bitcoin Are Subject To Specific Risks Relating To Security Threats.**

Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets, including bitcoin. The sponsor of the underlying has stated that it believes that the bitcoins held in the underlying's account at its bitcoin custodian or trading balance held with its prime execution agent will be an appealing target to hackers or malware distributors seeking to steal the underlying's bitcoins and will only become more appealing as the amount or value of the underlying's assets grow. To the extent that the underlying is unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, the underlying's bitcoins may be subject to theft, loss or other attack.

**Investments Linked To Bitcoin Are Subject To Specific Risks Relating To Fraud And Manipulation.**

Many digital asset platforms, both in the United States and abroad, are unlicensed, not subject to, or not in compliance with, regulation in relevant jurisdictions, or operate without extensive supervision by governmental authorities, and therefore may be more susceptible to fraudulent or manipulative acts and practices. In particular, those located outside the United States may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions and may take the position that they are not subject to laws and regulations that would apply to a regulated financial market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges, such as circuit breakers. Tools to detect and deter fraudulent or

---

manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset platforms, or may not exist at all. Sources of fraud and manipulation in the bitcoin market generally include, among others, (1) wash trading; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in digital asset markets and/or cause distortions in price, which could adversely affect the value of the underlying and, consequently, the securities.

**The Underlying Has Very Limited Historical Performance.**

The underlying began trading on January 11, 2024 and therefore has very limited historical performance. Past performance should not be considered indicative of future performance.

**The Underlying Is Not An Investment Company Or Commodity Pool And Will Not Be Subject To Regulation Under The Investment Company Act Of 1940, As Amended, Or The Commodity Exchange Act Of 1936, As Amended.**

Accordingly, you will not benefit from any regulatory protections afforded to persons who invest in regulated investment companies or commodity pools.

**The Performance And Market Price Of The Underlying, Particularly During Periods Of Market Volatility, May Not Correlate With The Performance Of Its Underlying Asset Or The Net Asset Value Per Share Of The Underlying.**

The underlying does not fully replicate the performance of its underlying asset, which is bitcoin, due to the fees and expenses charged by such underlying or by restrictions on access to its underlying asset due to other circumstances. The underlying does not generate any income, and as the underlying regularly sells its underlying asset to pay for ongoing expenses, the amount of the underlying asset represented by each share of such underlying gradually declines over time. The underlying sells its underlying asset to pay expenses on an ongoing basis irrespective of whether the trading price of the shares of such underlying rises or falls in response to changes in the price of its underlying asset. The sale by the underlying of its underlying asset to pay expenses at a time of relatively low prices for such underlying asset could adversely affect the value of the securities. Additionally, there is a risk that part or all of the holdings of the underlying in its underlying asset could be lost, damaged or stolen due to war, terrorism, theft, natural disaster or otherwise. Finally, because the shares of the underlying are traded on an exchange and are subject to market supply and investor demand, the market price of one share of the underlying may differ from the net asset value per share of the underlying.

In particular, during periods of market volatility or unusual trading activity, trading in the underlying's underlying asset may be disrupted or limited, or such underlying asset may be unavailable in the secondary market. Under these circumstances, the liquidity of the underlying may be adversely affected, market participants may be unable to calculate accurately the net asset value per share of the underlying, and their ability to create and redeem shares of the underlying may be disrupted. Under these circumstances, the market price of the underlying may vary substantially from the net asset value per share of the underlying or the performance of its underlying asset.

For all of the foregoing reasons, the performance of the underlying may not correlate with the performance of its underlying asset or the net asset value per share of the underlying. Any of these events could materially and adversely affect the price of the underlying and, therefore, the value of the securities. Additionally, if market volatility or these events were to occur on the final calculation day, the calculation agent would maintain discretion to determine whether such market volatility or events have caused a market disruption event to occur, and such determination may affect the maturity payment amount of the securities. If the calculation agent determines that no market disruption event has taken place, the maturity payment amount would be based on the published closing price per share of the underlying on the final calculation day, even if the underlying is underperforming its underlying asset and/or trading below the net asset value per share of the underlying.

**Our Offering Of The Securities Is Not A Recommendation Of The Underlying.**

The fact that we are offering the securities does not mean that we or Wells Fargo or its affiliates believe that investing in an instrument linked to the underlying is likely to achieve favorable returns. In fact, as we and Wells Fargo and its affiliates are each part of respective global financial institutions, our affiliates and affiliates of Wells Fargo may have positions (including short positions) in the underlying or in instruments related to the underlying, and may publish research or express opinions, that in each case are inconsistent with an investment linked to the underlying. These and other activities of our affiliates or of Wells Fargo or its affiliates may affect the closing value of the underlying in a way that negatively affects the value of and your return on the securities.

**The Closing Value Of The Underlying May Be Adversely Affected By Our Or Our Affiliates', Or By Wells Fargo And Its Affiliates', Hedging And Other Trading Activities.**

We expect to hedge our obligations under the securities through CGMI or other of our affiliates and/or Wells Fargo or its affiliates, who may take positions in the underlying or in financial instruments related to the underlying and may adjust such positions during the term of the securities. Our affiliates and Wells Fargo and its affiliates may also take positions in the underlying or in financial instruments related to the underlying 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 underlying 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 or Wells Fargo and its affiliates while the value of the securities declines.

**We And Our Affiliates And Wells Fargo And Its Affiliates May Have Economic Interests That Are Adverse To Yours As A Result Of Our And Their Respective Business Activities.**

Our affiliates and Wells Fargo and its 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 underlying 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 or Wells Fargo or its affiliates while the value of the securities declines. In addition, in the course of this business, we or our affiliates or Wells Fargo or its 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 the 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—General 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.

**The Securities Will Not Be Adjusted For All Events That Could Affect The Value Of The Shares Of The Underlying.**

Certain events may occur during the term of the securities that have a dilutive effect on the value of the shares of the underlying or otherwise adversely affect the market price of such shares. The calculation agent will make certain adjustments for some of these events, as described under "General Terms of the Securities" in the accompanying product supplement. However, an adjustment will not be made for all events that could have a dilutive or adverse effect on such shares or their market price, such as partial tender offers or additional public offerings of shares, and the adjustments that are made may not fully offset the dilutive or adverse effect of the particular event. Accordingly, the occurrence of any event that has a dilutive or adverse effect on the shares of the underlying may adversely affect what you receive at maturity or, if applicable, any other payment owed to you under the securities. Unlike an investor in the securities, a direct holder of such shares may receive an offsetting benefit from any such event that may not be reflected in an adjustment to the terms of the securities; therefore, you may experience dilution or adverse consequences in a circumstance in which a direct holder would not.

**If A Reorganization Event Occurs With Respect To The Underlying, The Calculation Agent May Make Adjustments To The Terms Of The Securities That Adversely Affect Your Return On The Securities.**

If a reorganization event occurs with respect to the underlying, the calculation agent will have discretion to make such adjustments to the terms of the securities as the calculation agent determines appropriate to account for the economic effect on the securities of such event. In such an event, the calculation agent may, but is not required to, select a successor fund to which the securities may become linked thereafter. In any case, the adjustments made by the calculation agent to the terms of the securities may adversely affect the value of and your return on the securities.

**Changes That Affect The Underlying May Affect The Value Of Your Securities.**

The sponsor of the underlying may at any time make methodological changes or other changes in the manner in which it operates that could affect the value of the underlying. We are not affiliated with the underlying sponsor and, accordingly, we have no control over any changes such sponsor may make. Such changes could adversely affect the performance of the underlying and the value of and your return on the securities.

**The Call Settlement Date And The Stated Maturity Date May Be Postponed If A Calculation Day Is Postponed.**

A calculation day (including the final calculation day) will be postponed for non-trading days and certain market disruption events. If such a postponement occurs, the call settlement date or maturity date, as applicable, will be postponed. For more information regarding adjustments to the calculation days and payment dates and the circumstances that may result in a market disruption event, see the relevant sections of the accompanying product supplement.

**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. Even if the treatment of the securities as prepaid forward contracts is respected, a security may be treated as a "constructive ownership transaction," with potentially adverse consequences described below under "United States Federal Tax Considerations." 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 "General Risk Factors Relating to All 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 Examples and Returns**

The payout profile, return table and examples below illustrate how to determine the payment on the securities, assuming the various hypothetical closing values indicated below. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of what the actual payment on the securities will be. The actual payment on the securities will depend on the actual closing values of the underlying on the calculation days.

The examples below are based on the following hypothetical values and do not reflect the actual starting value or threshold value of the underlying. For the actual starting value and threshold value of the underlying, see "Terms of the Securities" above. 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 on the securities will be calculated based on the actual starting value and threshold value of the underlying, and not the hypothetical values indicated below. The examples below assume that the call premium will be set at the lowest value indicated in "Terms of the Securities" above. The actual call premium will be determined on the pricing date.

**Hypothetical Examples**

***If the securities are automatically called:***

**Example 1—Automatic Call.** The hypothetical closing value of the underlying on the call date is $150, which is **greater than** the starting value.

Because the closing value of the underlying on the call date is greater than the starting value, the securities would be automatically called for redemption on the call settlement date for an amount in cash per security equal to $1,000 *plus* the call premium of 31.45% of the stated principal amount. In this example, the total payment upon automatic call would be $1,314.50 per security.

Even though the underlying on the call date appreciated by a percentage greater than the call premium from the starting value to the closing value on the call date in this example, your return is limited to the call premium. In this scenario, an investment in the securities would underperform a hypothetical alternative investment providing 1-to-1 exposure to the appreciation of the underlying. If the securities are automatically called for redemption, they will cease to be outstanding on the call settlement date and you will have no further rights under the securities after the call settlement date.

***If the securities are not automatically called:***

**Example 2—Upside Scenario.** The hypothetical ending value $110, which is **greater than** the starting value.

Maturity payment amount per security = $1,000 + ($1,000 × underlying return × participation rate)

= $1,000 + ($1,000 × 10% × 150%)

= $1,000 + $150.00

= $1,150.00

Because the underlying appreciated from the starting value to the hypothetical ending value, you would receive a total return at maturity equal to the upside performance of the underlying *multiplied by* the participation rate.

**Example 3—Absolute Return Scenario.** The hypothetical ending value is $95, which is **less than** the starting value but **greater than** the threshold value.

Maturity payment amount per security = $1,000 + ($1,000 × absolute value of underlying return)

= $1,000 + ($1,000 × \|-5.00%\|)

= $1,000 + ($1,000 × 5.00%)

= $1,000 + $50

= $1,050

Because the hypothetical ending value is less than the starting value but greater than the threshold value, your total return at maturity in this scenario would reflect positive exposure to the absolute value of the negative performance of the underlying.

**Example 4—Downside Scenario.**The hypothetical ending value is $30, which is **less than** the threshold value.

Maturity payment amount per security = $1,000 + ($1,000 × underlying return)

= $1,000 + ($1,000 × -70%)

= $1,000 + -$700

= $300

Because the hypothetical ending value is less than the hypothetical threshold value, your maturity payment amount in this scenario would reflect 1-to-1 exposure to the negative performance of the underlying.

<br> **Information About the iShares<sup>®</sup> Bitcoin Trust ETF**

The iShares<sup>®</sup> Bitcoin Trust ETF is a Delaware statutory trust sponsored by iShares<sup>®</sup> Delaware Trust Sponsor LLC that seeks to reflect generally the performance of the price of bitcoin, which is its underlying asset, before the payment of the iShares<sup>®</sup> Bitcoin Trust ETF's expenses and liabilities. The assets of the iShares<sup>®</sup> Bitcoin Trust ETF consist primarily of bitcoin held by a custodian on behalf of the iShares<sup>®</sup> Bitcoin Trust ETF. Information provided to or filed with the Securities and Exchange Commission by the iShares<sup>®</sup> Bitcoin Trust ETF pursuant to the Securities Exchange Act of 1934 can be located by reference to Securities and Exchange Commission file number 001-41914 through the Securities and Exchange Commission's website at www.sec.gov. In addition, information regarding the iShares<sup>®</sup> Bitcoin Trust ETF may be obtained from other publicly available sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. The shares of the iShares<sup>®</sup> Bitcoin Trust ETF trade on the Nasdaq Stock Market under the ticker symbol "IBIT."

The sponsor of the iShares<sup>®</sup> Bitcoin Trust ETF is iShares<sup>®</sup> Delaware Trust Sponsor LLC, an indirect subsidiary of BlackRock, Inc.; BlackRock Fund Advisors is the trustee of the iShares<sup>®</sup> Bitcoin Trust ETF; Coinbase Custody Trust Company, LLC is the custodian for the iShares<sup>®</sup> Bitcoin Trust ETF's bitcoin holdings; Coinbase, Inc., an affiliate of Coinbase Custody Trust Company, LLC, is the prime execution agent; the Bank of New York Mellon is the custodian for the iShares<sup>®</sup> Bitcoin Trust ETF's cash holdings and the administrator of the iShares<sup>®</sup> Bitcoin Trust ETF; and Wilmington Trust, National Association, a national association, serves as the Deleware trustee of the iShares<sup>®</sup> Bitcoin Trust ETF.

The iShares<sup>®</sup> Bitcoin Trust ETF issues (in blocks of 40,000 shares, each of which is referred to as a "basket") shares representing fractional undivided beneficial interests in its net assets. The assets of the iShares<sup>®</sup> Bitcoin Trust ETF consist primarily of bitcoin held by a custodian on behalf of the iShares<sup>®</sup> Bitcoin Trust ETF. The shares of the iShares<sup>®</sup> Bitcoin Trust ETF are intended to constitute a simple and cost-effective means of making an investment similar to an investment in bitcoin rather than by acquiring, holding and trading bitcoin directly on a peer-to-peer or other basis or via a digital asset platform. The trustee of the iShares<sup>®</sup> Bitcoin Trust ETF sells bitcoin held by the iShares<sup>®</sup> Bitcoin Trust ETF to pay the iShares<sup>®</sup> Bitcoin Trust ETF's expenses on an as-needed basis irrespective of then-current bitcoin prices.

The iShares<sup>®</sup> Bitcoin Trust ETF is not actively managed and will not take any actions to take advantage, or mitigate the impacts, of volatility in the price of bitcoin. The iShares<sup>®</sup> Bitcoin Trust ETF pays the sponsor's fee, which accrues daily at an annualized rate equal to 0.25% of the net asset value of the iShares<sup>®</sup> Bitcoin Trust ETF, at least quarterly in arrears. The trustee of the iShares<sup>®</sup> Bitcoin Trust ETF will, when directed by the sponsor of the iShares<sup>®</sup> Bitcoin Trust ETF, and, in the absence of such direction, may in its discretion, sell bitcoin in such quantity and at such times as may be necessary to permit payment of the sponsor's fee and trust expenses or liabilities not assumed by the sponsor. As a result of the recurring sales of bitcoin necessary to pay the sponsor's fee and trust expenses or liabilities not assumed by the sponsor, the net asset value of the iShares<sup>®</sup> Bitcoin Trust ETF will decrease over the life of the trust. New purchases of bitcoin utilizing cash proceeds from new shares issued by the iShares<sup>®</sup> Bitcoin Trust ETF do not reverse this trend. A decrease in the amount of bitcoin represented by each share of the iShares<sup>®</sup> Bitcoin Trust ETF is expected to result in a decrease in the price of the shares of the iShares<sup>®</sup> Bitcoin Trust ETF, even if the price of bitcoin has not changed. To retain the iShares<sup>®</sup> Bitcoin Trust ETF shares' original price, the price of bitcoin would likely have to increase. Without that increase, the lesser amount of bitcoin represented by each share of the iShares<sup>®</sup> Bitcoin Trust ETF would be expected to cause the shares of the iShares<sup>®</sup> Bitcoin Trust ETF to have a correspondingly lower price. If these increases do not occur, or are not sufficient to counter the lesser amount of bitcoin represented by each share of the iShares<sup>®</sup> Bitcoin Trust ETF, the price of the shares of the iShares<sup>®</sup> Bitcoin Trust ETF will likely decrease.

We have derived all information regarding the iShares<sup>®</sup> Bitcoin Trust ETF from publicly available information and have not independently verified any information regarding the iShares<sup>®</sup> Bitcoin Trust ETF. This pricing supplement relates only to the securities and not to the iShares<sup>®</sup> Bitcoin Trust ETF. We make no representation as to the performance of the iShares<sup>®</sup> Bitcoin Trust ETF over the term of the securities.

The securities represent obligations of Citigroup Global Markets Holdings Inc. (guaranteed by Citigroup Inc.) only. The sponsor of the iShares<sup>®</sup> Bitcoin Trust ETF is not involved in any way in this offering and has no obligation relating to the securities or to holders of the securities.

***Bitcoin.*** Bitcoin is a digital asset, the ownership and behavior of which are determined by participants in an online, peer-to-peer network that connects computers that run publicly accessible, or "open source," software that follows the rules and procedures governing the bitcoin network, commonly referred to as the bitcoin protocol. The value of bitcoin, like the value of other digital assets, is not backed by any government, corporation or other identified body. Ownership and the ability to transfer or take other actions with respect to bitcoin are protected through public-key cryptography. The supply of bitcoin is constrained or formulated by its protocol instead of being explicitly delegated to an identified body (e.g., a central bank) to control. Units of bitcoin, called tokens, are treated as fungible. Bitcoin and certain other types of digital assets are often referred to as digital currencies or cryptocurrencies. No single entity owns or operates the bitcoin network, the infrastructure of which is collectively maintained by (1) a decentralized group of participants who run computer software that results in the recording and validation of transactions (commonly referred to as "miners"), (2) developers who propose improvements to the bitcoin protocol and the software that enforces the protocol and (3) users who choose what bitcoin software to run.

**United States Federal Tax Considerations**

You should read carefully the discussion under "United States Federal Tax Considerations" and "General Risk Factors Relating to All 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;· Upon a sale or exchange of a security (including retirement at maturity), you should recognize gain or
loss equal to the difference between the amount realized and your tax basis in the security. Subject to the discussion below
concerning the potential application of the "constructive ownership" rules under Section 1260 of the Code, any gain or loss
recognized upon a sale, exchange or retirement of a security should be long-term capital gain or loss if you held the security for more
than one year.

Even if the treatment of the securities as prepaid forward contracts is respected, your purchase of a security may be treated as entry into a "constructive ownership transaction," within the meaning of Section 1260 of the Code. In that case, all or a portion of any long-term capital gain you would otherwise recognize in respect of your securities would be recharacterized as ordinary income to the extent such gain exceeded the "net underlying long-term capital gain." Any long-term capital gain recharacterized as ordinary income under Section 1260 would be treated as accruing at a constant rate over the period you held your securities, and you would be subject to an interest charge in respect of the deemed tax liability on the income treated as accruing in prior tax years. Due to the lack of governing authority under Section 1260, our counsel is not able to opine as to whether or how Section 1260 applies to the securities. You should read the section entitled "United States Federal Tax Considerations—Tax Consequences to U.S. Holders—Securities Treated as Prepaid Forward Contracts—Possible Application of Section 1260 of the Code" in the accompanying product supplement for additional information and consult your tax adviser regarding the potential application of the "constructive ownership" rule.

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**

Pursuant to the terms of the Amended and Restated Global Selling Agency Agreement, dated April 7, 2017, CGMI, acting as principal, will purchase the securities from Citigroup Global Markets Holdings Inc. CGMI, as the lead agent for the offering, expects to sell the securities to Wells Fargo, as agent. Wells Fargo will receive an underwriting discount and commission of up to 2.325% ($23.25) for each security it sells. Wells Fargo may pay selected dealers, which may include WFA, a fixed selling commission of 1.75% ($17.50) for each security they sell. In addition to the selling commission allowed to WFA, Wells Fargo may pay $0.75 per security of the underwriting discount and commission to WFA as a distribution expense fee for each security sold by WFA.

In addition, in respect of certain securities sold in this offering, CGMI may pay a fee of up to $1.00 per security to selected securities dealers in consideration for marketing and other services in connection with the distribution of the securities to other securities dealers.

For the avoidance of doubt, the fees and selling concessions described in this pricing supplement will not be rebated if the securities are automatically called for redemption.

**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.

We have been advised that, for a period of approximately three months following issuance of the securities, the price, if any, at which Wells Fargo 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 Wells Fargo or its affiliates, 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 costs associated with selling, structuring and hedging the securities that are included in the public offering price 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, Wells Fargo is not obligated to buy the securities from investors at any time.
