Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering Autocallable Barrier Securities linked to the S&P 500® Equal Weight Index under its Medium-Term Senior Notes, Series N program.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Filing Summary
Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering Autocallable Barrier Securities linked to the S&P 500® Equal Weight Index under its Medium-Term Senior Notes, Series N program. Each security has a $1,000 stated principal amount, a pricing date of July 23, 2026, issue date of July 28, 2026, and, if not called, matures on July 28, 2031.
The notes may be automatically redeemed on July 30, 2027 if the index closing value is at or above its initial value, paying $1,097 per security ($1,000 principal plus a 9.70% premium). If not redeemed, the maturity payment depends on the index level on the final valuation date: investors participate in upside with a 150% upside participation rate when the final value exceeds the initial value, receive par if the index finishes between the initial value and the final barrier value of 80.00% of the initial value, and incur 1‑for‑1 downside exposure below the barrier, potentially losing most or all of principal.
The issue price is $1,000 per security, including an underwriting fee of up to $22, leaving $978 in proceeds to the issuer per security. Citigroup Global Markets Inc. expects the estimated value on the pricing date to be at least $915 per security, reflecting selling, structuring and hedging costs and the issuer’s internal funding rate. The securities do not pay dividends or provide any rights in the underlying index and are subject to complex market, credit and tax risks, including potential U.S. tax treatment as a prepaid forward contract and possible future changes under Section 871(m) for non‑U.S. holders.

Autocallable Barrier Securities Linked to the S&P 500® Equal Weight Index Due July 28, 2031
| ▪ | 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 the terms described below. Your return on the securities will depend on the performance of the underlying specified below. |
| ▪ | The securities offer the potential for automatic early redemption at a premium following the valuation date prior to the final valuation date if the closing value of the underlying is greater than or equal to the initial underlying value. If the securities are not automatically redeemed prior to maturity, the securities will no longer offer the opportunity to receive a premium, but instead, at maturity, will provide for (i) the opportunity to participate in any appreciation of the underlying from the initial underlying value at the upside participation rate specified below and (ii) contingent repayment of the stated principal amount at maturity if the underlying depreciates, but only so long as the final underlying value is greater than or equal to the final barrier value specified below. However, if the securities are not automatically redeemed prior to maturity and the final underlying value is less than the final barrier value, you will lose 1% of the stated principal amount of your securities for every 1% by which the final underlying value is less than the initial underlying value. You may lose a significant portion, and up to all, of your investment. Although you will have downside exposure to the underlying, you will not receive dividends with respect to the underlying. |
| ▪ | In order to obtain the modified exposure to the underlying that the securities provide, investors must be willing to accept (i) an investment that may have limited or no liquidity and (ii) the risk of not receiving any amount 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. |

(1) Citigroup Global Markets Holdings Inc. currently expects that the estimated value of the securities on the pricing date will be at least $915.00 per security, which will be less than the issue price. The estimated value of the securities is based on CGMI’s 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 CGMI or any other 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 will receive an underwriting fee of up to $22.00 for each security sold in this offering. The total underwriting fee and proceeds to issuer in the table above give effect to the actual total underwriting fee. From this underwriting fee, CGMI will pay selected dealers not affiliated with CGMI a selling concession of $20.00 for each security they sell and a structuring fee of up to $2.00 for each security they sell. For more information on the distribution of the securities, see “Supplemental Plan of Distribution” in this pricing supplement. In addition to the underwriting fee, CGMI and its affiliates may profit from expected hedging activity related to this offering, even if the value of the securities declines. See “Use of Proceeds and Hedging” in the accompanying prospectus. In addition, CGMI will pay to one or more electronic platform providers a fee for each security sold in this offering where related selected dealers and/or custodians implement or utilize such providers.
(3) The per security proceeds to issuer indicated above represent the minimum per security proceeds to issuer for any security, assuming the maximum per security underwriting fee. As noted above, the underwriting fee is variable.
Investing in the securities involves risks not associated with an investment in conventional debt securities. See “Summary Risk Factors” beginning on page PS-5.

Hypothetical Payment Upon Automatic Early Redemption
The following table illustrates how the amount payable per security upon automatic early redemption will be calculated if the closing value of the underlying on the valuation date prior to the final valuation date is greater than or equal to the initial underlying value.
| If the closing value of the underlying on the valuation date below is greater than or equal to the initial underlying value. . . | . . . then you will receive the following payment per security upon automatic early redemption: |
| July 30, 2027 | $1,000 + applicable premium = $1,000 + $97.00 = $1,097.00 |
If, on the valuation date prior to the final valuation date, the closing value of the underlying is less than the initial underlying value, you will not receive the premium indicated above following that valuation date. In order to receive the premium indicated above, the closing value of the underlying on the valuation date prior to the final valuation date must be greater than or equal to the initial underlying value.
Payment at Maturity Diagram
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 underlying returns.
Investors in the securities will not receive any dividends with respect to the underlying. 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 underlying” below.

Hypothetical Examples of the Payment at Maturity
The examples below illustrate how to determine the payment at maturity on the securities, assuming the securities are not automatically redeemed prior to maturity and assuming the various hypothetical final underlying 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 at maturity on the securities will be. The actual payment at maturity will depend on the actual final underlying value.
The examples below are based on a hypothetical initial underlying value of 100 and a hypothetical final barrier value of 80 and do not reflect the actual initial underlying value or final barrier value. For the actual initial underlying value and final barrier value, 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 and final barrier value, and not the hypothetical values indicated below. For ease of analysis, figures below have been rounded.
Example 1—Upside Scenario. The final underlying value is 110 (a 10.00% increase from the initial underlying value), which is greater than the initial underlying value.
Payment at maturity per security = $1,000 + the return amount
= $1,000 + ($1,000 × the underlying return × the upside participation rate)
= $1,000 + ($1,000 × 10.00% × 150.00%)
= $1,000 + $150.00
= $1,150.00
In this scenario, the underlying has appreciated from the initial underlying value to the final underlying value, and your total return at maturity would equal the underlying return multiplied by the upside participation rate.
Example 2—Par Scenario. The final underlying value is 95 (a 5.00% decrease from the initial underlying value), which is less than the initial underlying value but greater than the final barrier value.
Payment at maturity per security = $1,000
In this scenario, the underlying has depreciated from the initial underlying value to the final underlying value, but not below the final barrier value. Because the final underlying value is greater than the final barrier value, you would be repaid the stated principal amount of $1,000 per security at maturity but would not receive any positive return on your investment.
Example 3—Downside Scenario. The final underlying value is 30 (a 70.00% decrease from the initial underlying value), which is less than the final barrier value.
Because the final underlying value is less than the final barrier value, you would receive a payment at maturity per security that is less than the stated principal amount, calculated as follows:
Payment at maturity per security = $1,000 + ($1,000 × the underlying return)
= $1,000 + ($1,000 × -70.00%)
= $1,000 + -$700.00
= $300.00
In this scenario, the underlying has depreciated from the initial underlying value to the final underlying value and the final underlying value is less than the final barrier 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 underlying.

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 suitable only for investors who are capable of understanding the complexities and risks of the securities. You should consult your own financial, tax and legal advisors as to the risks of an investment in the securities and the suitability of the securities in light of your particular circumstances.
The following is a summary of certain key risk factors for investors in the securities. You should read this summary together with the more detailed description of risks relating to an investment in the securities contained in the section “Risk Factors Relating to the Securities” beginning on page EA-6 in the accompanying product supplement. You should also carefully read the risk factors included in the accompanying prospectus supplement and in the documents incorporated by reference in the accompanying prospectus, including Citigroup Inc.’s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which describe risks relating to the business of Citigroup Inc. more generally.
| § | You may lose a significant portion 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 underlying value. If the final underlying value is less than the final barrier value, you will lose 1% of the stated principal amount of the securities for every 1% by which the underlying has declined from the initial underlying value. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment. |
| § | 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 closing value of the underlying on the valuation date prior to the final valuation date is greater than or equal to the initial underlying value, the securities will be automatically redeemed. If the securities are automatically redeemed following the valuation date prior to the final valuation date, they will cease to be outstanding and you will not have the opportunity to participate in any appreciation of the underlying. Moreover, you may not be able to reinvest your funds in another investment that provides a similar yield with a similar level of risk. |
| § | You will not receive dividends or have any other rights with respect to the underlying. You will not receive any dividends with respect to the underlying. 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 underlying or the stocks included in the underlying. |
| § | The performance of the securities will depend on the closing values of the underlying solely on the valuation dates, which makes the securities particularly sensitive to volatility in the closing values of the underlying on or near the valuation dates. Whether the securities will be automatically redeemed prior to maturity will depend on the closing values of the underlying solely on the valuation date prior to the final valuation date, regardless of the closing values of the underlying 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 closing value of the underlying on the final valuation date, and not on any other day during the term of the securities. Because the performance of the securities depends on the closing 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 on or near the valuation dates. 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. 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
| PS-5 |
| Citigroup Global Markets Holdings Inc. |
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 closing value of the underlying, the dividend yield on 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 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 value of the underlying, the volatility of the closing value of the underlying, the dividend yield on 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 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 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 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 S&P 500® Equal Weight Index may underperform the S&P 500® Index. The S&P 500® Equal Weight Index is composed of the same constituents as the S&P 500® Index, but weights those constituents equally (as rebalanced each quarter) rather than based on market capitalization as in the S&P 500® Index. As a result, the companies with the largest market capitalizations will have a smaller impact on the performance of the S&P 500® Equal Weight Index than on the performance of the S&P 500® Index. If larger market capitalization companies outperform smaller market capitalization companies, then the S&P 500® Equal Weight Index will underperform the S&P 500® Index, perhaps significantly. |
§ 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 believe that investing in an instrument linked to the underlying is likely to achieve favorable returns. In fact, as we are part of a global financial institution, our affiliates may have positions (including short positions) in the underlying or in instruments related to the underlying, and may publish research or express opinions, that in each case are inconsistent with an investment
| PS-6 |
| Citigroup Global Markets Holdings Inc. |
linked to the underlying. These and other activities of our 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’ 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 underlying or in financial instruments related to the underlying and may adjust such positions during the term of the securities. Our affiliates 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 value 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 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 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 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 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 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 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 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.

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 $22.00 for each security sold in this offering. The actual underwriting fee will be equal to the selling concession and structuring fee provided to selected dealers, as described in this paragraph. From this underwriting fee, CGMI will pay selected dealers not affiliated with CGMI a selling concession of $20.00 for each security they sell and a structuring fee of up to $2.00 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 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 four 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 four-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 S&P 500® Equal Weight Index
The S&P 500® Equal Weight Index
The S&P 500® Equal Weight Index is calculated, maintained and published by S&P Dow Jones Indices LLC (“S&P Dow Jones”). All information contained in this pricing supplement regarding the S&P 500® Equal Weight Index, 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, S&P Dow Jones. S&P Dow Jones has no obligation to continue to publish, and may discontinue the publication of, the S&P 500® Equal Weight Index. The securities represent obligations of Citigroup Global Markets Holdings Inc. (guaranteed by Citigroup Inc.) only. S&P Dow Jones is not involved in any way in this offering and has no obligation relating to the securities or to holders of the securities.
The S&P 500® Equal Weight Index began publishing on January 8, 2003 and has a base date of December 29, 1989. The price return version of the S&P 500® Equal Weight Index is reported by Bloomberg, L.P. under the ticker symbol “SPW.”
The S&P 500® Equal Weight Index is designed to be the size-neutral version of the S&P 500® Index. The S&P 500® Equal Weight Index employs the same eligibility criteria and constituent changes as the S&P 500® Index, and the S&P 500® Equal Weight Index has the same constituents as the S&P 500® Index. At each quarterly rebalancing, each constituent of the S&P 500® Equal Weight Index is allocated the same weight as every other constituent in the index.
Index Construction
The S&P 500® Equal Weight Index is an equal-weighted version of the S&P 500® Index. Index composition is the same as the S&P 500® Index. Constituent changes are incorporated in the S&P 500® Equal Weight Index as and when they are made in the S&P 500® Index. For additional information about the S&P 500® Index, including the methodology for inclusion in the S&P 500® Index, see “Equity Index Descriptions—The S&P U.S. Indices” in the accompanying underlying supplement.
When a company is added to the S&P 500® Equal Weight Index in the middle of the quarter, it takes the weight of the company that it replaced. The one exception is when a company is removed from the S&P 500® Equal Weight Index at a price of $0.00. In such a case, the company’s replacement is added to the index at the weight using the previous day’s closing value, or the most immediate prior business day that the deleted company was not valued at $0.00.
Weighting
The S&P 500® Equal Weight Index is an equal-weighted index, meaning an index where every stock, or company, has the same weight in the index. As stock prices move, the weights will shift and exact equality will be lost. Therefore, an equal weighted index must be rebalanced from time to time to re-establish the proper weighting.
The S&P 500® Equal Weight Index is reset to equal weight quarterly after the close of business on the third Friday of March, June, September, and December. The reference date for weighting is the second Friday of the reweighting month and changes are effective after the close of the following Friday using prices as of the reweighting reference date, and membership, shares outstanding, and investable weight factors (“IWF”) as of the reweighting effective date. For those companies having multiple share class lines in the index, each share class line is assigned a weight that is proportional to its float-adjusted market capitalization as of the second Friday pricing reference date. Since index shares are assigned based on prices one week prior to the rebalancing, the actual weight of each company at the rebalancing differs from the target equal weights due to market movements.
Index Calculation
The overall approach to calculate the value of the S&P 500® Equal Weight Index is the same as the S&P 500® Index; except that each constituent’s market value in the S&P 500® Index is multiplied by its additional weight factor (AWF). The AWF is a number used to convert a constituent’s market value in the S&P 500® Index into an equal weight in the S&P 500® Equal Weight Index at the most recent quarterly rebalancing, while maintaining the total market value of the S&P 500® Index. Between quarterly rebalancings, the AWFs are fixed and therefore the weights of the constituents in the S&P 500® Equal Weight Index will shift as constituent prices increase or decrease. In order to re-establish equal weighting, new AWFs are calculated on a quarterly basis.
Index Maintenance
Several types of corporate actions, and their related treatment, are listed in the table below.
| Corporate Action | Treatment |
| Company addition/deletion |
Fixed Component Count Index Treatment (Stock Replacements)
The company entering the index goes in at the weight of the company coming out. If a company is being removed at a price of $0.00, the replacement goes in at the weight of the deleted company at the close on the day before the effective date. If more than one company is being replaced in the index on a single date, the replacements are |

|
added in the order specified in the client announcement. There will be no change in index market capitalization and no divisor change for stock replacements except where a company is removed at a price of zero as noted above.
Deletion
The weights of all stocks in the index will proportionately change, due to the absolute change in the number of index constituents. Relative weights will stay the same. The index divisor will change due to the net change in the index market capitalization | |
| Change in shares outstanding | Shares outstanding changes are offset by an AWF. There is no change to the index market capitalization and no divisor adjustment. |
| Split/reverse split | Shares outstanding are adjusted by split ratio. Stock price is adjusted by split ratio. There is no change to the index market capitalization and no divisor adjustment. |
| Change in IWF | IWF changes are offset by an AWF. There is no change to the index market capitalization and no divisor adjustment. |
| Special dividend | The stock price is adjusted by the amount of the dividend. The net change to the index market capitalization causes a divisor adjustment |
| Rights offering | All rights offerings that are in the money on the ex-date are applied under the assumption the rights are fully subscribed. The stock price is adjusted by the value of the rights and the shares outstanding are increased by the rights ratio. The change in price and shares is offset by an AWF to keep the index market capitalization (stock weight) unchanged. There is no change to the index market capitalization and no divisor adjustment. |
Comparison of Historical S&P 500® Equal Weight Index Performance Against Historical S&P 500® Index Performance
The following graph sets forth a comparison of the historical performance of the S&P 500® Equal Weight Index against the historical performance of the S&P 500® Index from January 4, 2016 through July 20, 2026, each normalized to have a closing value of 100.00 on January 4, 2016 to facilitate a comparison. In the graph below, references to “SPW” are to the S&P 500® Equal Weight Index and references to “SPX” are to the S&P 500® Index.
