Any capitalized term not defined herein shall have the meaning set forth in the preliminary pricing supplement to which the term sheet relates (see hyperlink below).1SEC File No. 333-285508\| November 07, 2025TERMS CONTINUEDIf the closing level of each Reference Asset on an Observation Date is greater than or equal to its Coupon Barrier Level, on the corresponding Contingent Coupon Payment Date you will receive (i) a Contingent Coupon (calculated at the Contingent Interest Rate) in respect of that Observation Date and (ii) any previously unpaid Contingent Coupons in respect of any prior Observation Dates pursuant to the Memory Coupon Feature. Please see page 2 hereof for the Contingent Coupon Payment Dates and Observation Dates. Contingent Coupons:If a Contingent Coupon is not paid on a Coupon Payment Date (other than the Maturity Date) because the closing level of a Reference Asset is less than its Coupon Barrier Level on the related Observation Date, such Contingent Coupon will be paid on a later Contingent Coupon Payment Date if the closing level of each Reference Asset is greater than or equal to its Coupon Barrier Level on the relevant Observation Date.Memory Coupon Feature:Beginning on May 15, 2026, if, on any Observation Date, the closing level of each Reference Asset is greater than or equal to its Call Level, the notes will be automatically redeemed.

As such, the notes may be suitable for investors with a moderately bullish view of the Reference Assets over the term of the notes. The performance of the notes may not be consistent with the investment objective. This term sheet, which gives a brief summary of the terms of the notes, relates to, and should be read in conjunction with, the preliminary pricing supplement dated November 05, 2025, the Product Supplement dated March 25, 2025, the Prospectus Supplement dated March 25, 2025, and to the Prospectus dated March 25, 2025.CITIGROUP GLOBAL MARKETS INC.

You will receive $1,000 for each $1,000 in principal amount of the note, unless a Trigger Event has occurred.If a Trigger Event has occurred, you will receive at maturity, for each $1,000 in principal amount of your notes, a cash amount equal to:$1,000 + [$1,000 x (Percentage Change of the Least Performing Reference Asset)]This amount will be less than the principal amount of your notes, and may be zero.Payment at Maturity (if held to the Maturity Date):The Reference Asset that has the lowest Percentage Change. Least Performing Reference Asset:The Percentage Change of each Reference Asset, expressed as a percentage, is calculated using the following formula:(Final Level ?Initial Level) / Initial Level Percentage Change:With respect to each Reference Asset, the closing level of such Reference Asset on the Pricing Date.Initial Level:With respect to each Reference Asset, the closing level of such Reference Asset on the Valuation Date.Final Level:Investors in these notes could lose all or a substantial portion of their investment at maturity if there has been a decline in the market value of any Reference Asset and the Final Level of any Reference Asset is less than its Trigger Level. We urge you to carefully review the documents described in "Additional Information" below, including the risk factors set forth and incorporated by reference therein, prior to making an investment decision.Principal at Risk:The notes will not be listed on any securities exchange. Although not obligated to do so, Citigroup Global Markets Inc. ("Citigroup") (or one or more of our or their affiliates), plans to maintain a secondary market in the notes after the Settlement Date.

3The risks summarized below are some of the most important factors to be considered prior to any purchase of the notes. Investors are urged to read all the risk factors related to the notes in the pricing supplement and the product supplement to which this term sheet relates.? You could lose up to the entire principal amount of your notes, and your potential return on the notes is limited to any Contingent Coupon payments, if any. If the notes are not automatically redeemed and if a Trigger Event has occurred with respect to any Reference Asset, and if the Final Level of any Reference Asset is less than its Initial Level, you will lose 1% of the principal amount for each 1% that the Final Level of the Least Performing Reference Asset is less than its Initial Level.? You may not receive any Contingent Coupons with respect to your notes.? Your notes are subject to automatic early redemption. If the notes are so redeemed, you will not receive any additional Contingent Coupons, and you may not be able to invest the proceeds in a security with a similar return.? Your return on the notes is limited to the Contingent Coupons, if any, regardless of any increase in the level of any Reference Asset.? Whether you receive any Contingent Coupons and your payment at maturity may be determined solely by reference to the least performing Reference Asset, even if any other Reference Assets perform better. ? The payments on the notes will be determined by reference to each Reference Asset individually, not to a basket, and the payments on the notes will be based on the performance of the least performing Reference Asset.? Your return on the notes may be lower than the return on a conventional debt security of comparable maturity.?A higher Contingent Interest Rate or lower Trigger Levels or Coupon Barrier Levels may reflect greater expected volatility of the Reference Assets, and greater expected volatility generally indicates an increased risk of loss at maturity.? Owning the notes is not the same as a hypothetical direct investment in the Reference Assets or a security directly linked to the Reference Assets. ? You will not have any shareholder rights and will have no right to receive any shares of any company included in a Reference Asset at maturity. ? Neither we nor Citigroup have any affiliation with any index sponsor and will not be responsible for any index sponsor's actions.? You must rely on your own evaluation of the merits of an investment linked to the Reference Assets. ? An investment in the notes is subject to risks associated with foreign security markets.? An investment in the notes is subject to risks associated with foreign currency exchange rate risk.? The notes are unsecured debt obligations of the Issuer and your investment is subject to the credit risk of the Issuer.? Our, Citigroup and our and their affiliates' activities may conflict with your interests and may also adversely affect the value of the notes.? Our initial estimated value of the notes will be lower than the price to public, does not represent any future value of the notes, and may also differ from the estimated value of any other party.? The terms of the notes are not determined by reference to the credit spreads for our conventional fixed-rate debt.? The inclusion of the hedging profits, if any, in the initial price to public of the notes, as well as our hedging costs, is likely to adversely affect the price at which you can sell your notes.? The notes will not be listed on any securities exchange. We, Citigroup or one or more of our or their affiliates may offer to purchase the notes in the secondary market, but are not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily.? We, Citigroup and our or their affiliates may engage in hedging and trading activities related to the notes that could adversely affect our payment to you at maturity.Selected Risk Considerations:

4Hypothetical Calculations for the Payment at Maturity:Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in the notes The following table illustrates the hypothetical payments on a note at maturity, assuming that the notes are not automatically redeemed. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of 100.00, a hypothetical Trigger Level of 80.00 for each Reference Asset (80.00% of the hypothetical Initial Level), a hypothetical Call Level of 100.00 (100.00% of the hypothetical Initial Level), a range of hypothetical Final Levels and the effect on the payment at maturity. The hypothetical examples shown below are intended to help you understand the terms of the notes. If the notes are not automatically redeemed, the actual cash amount that you will receive at maturity will depend upon the Final Level of the Least Performing Reference Asset. If the notes are automatically redeemed prior to maturity, the hypothetical examples below will not be relevant, and you will receive on the applicable Call Settlement Date, for each $1,000 principal amount, the principal amount plus any Contingent Coupons otherwise due.These examples do not give effect to any U.S. federal tax payments or brokerage commissions that you may be required to pay in connection with your purchase of the notes.Hypothetical Final Level of the Least Performing Reference AssetHypothetical Final Level of the Least Performing Reference Asset Expressed as a Percentage of its Initial Level Payment at Maturity (Excluding Coupons)200.00 200.00% $1,000.00 180.00 180.00% $1,000.00 160.00 160.00% $1,000.00 140.00 140.00% $1,000.00 120.00 120.00% $1,000.00 100.00 100.00% $1,000.00 90.00 90.00% $1,000.00 80.00 80.00% $1,000.00 79.99 79.99% $799.90 60.00 60.00% $600.00 40.00 40.00% $400.00 20.00 20.00% $200.00 0.00 0.00% $0.00
