You are not assured of receiving any contingent coupon. If the closing value of the underlying on one or more valuation dates is less than the coupon barrier and, on a subsequent valuation date, the closing value of the underlying is greater than or equal to the coupon barrier, your contingent coupon payment for that subsequent valuation date will include all previously unpaid contingent coupon payments. Contingent coupon: 55.00% of the initial underlying value Coupon barrier: 55.00% of the initial underlying value Final barrier value: The stated principal amount divided by the initial underlying value Equity ratio: If on any autocall date the closing value of the underlying is greater than or equal to the initial underlying value, the securities will be automatically called for an amount equal to the principal plus the related contingent coupon Automatic early redemption: Monthly on valuation dates, beginning after six months Autocall dates: 17331B6R5 / US17331B6R51 CUSIP / ISIN: The closing value on the pricing date Initial underlying value: The closing value on the final valuation date Final underlying value: • If the final underlying value is greater than or equal to the final barrier value: $1,000 • If the final underlying value is less than the final barrier value: a fixed number of underlying shares of the underlying equal to the equity ratio (or, if we elect, the cash value of those shares based on the final underlying value) If the securities are not automatically redeemed prior to maturity and the final underlying value is less than the final barrier value, you will receive underlying shares (or, in our sole discretion, cash) that will be worth significantly less than the stated principal amount of your securities, and possibly nothing, at maturity, and you will not receive any contingent coupon payment at maturity (including any previously unpaid contingent coupon payments). Payment at maturity (if not autocalled): $1,000 per security Stated principal amount: Preliminary Pricing Supplement dated January 2, 2026 Pricing Supplement: \* The actual contingent coupon rate will be determined on the pricing date. \*\* Assumes that the valuation date is also an autocall date and that the securities have not been previously redeemed.

Selected Risk Considerations • 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 and the final underlying value is less than the final barrier value, you will not receive the stated principal amount of your securities at maturity and, instead , will receive underlying shares of the underlying (or, in our sole discretion, cash based on the value thereof) that will be worth significantly less than the stated principal amount and possibly nothing. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment. • You will not receive any contingent coupon following any valuation date on which the closing value of the underlying on that valuation date is less than its coupon barrier. • The securities may be automatically redeemed prior to maturity, limiting your opportunity to receive contingent coupons if the underlying performs in a way that would otherwise be favorable. • The securities offer downside exposure, but no upside exposure, to the underlying. • The performance of the securities will depend on the closing value of the underlying solely on the valuation dates, which makes the securities particularly sensitive to volatility in the closing value of the underlying on or near the valuation dates. • The securities are unsecured debt securities and are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. If Citigroup Global Markets Holdings Inc. defaults on its 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 estimated value of the securities on the pricing date will be less than the issue price. For more information about the estimated value of the securities, see the accompanying preliminary pricing supplement. • The value of the securities prior to maturity will fluctuate based on many unpredictable factors. • The issuer and its affiliates may have conflicts of interest with you. • The U.S. federal tax consequences of an investment in the securities are unclear. The above summary of selected risks does not describe all of the risks associated with an investment in the securities. You should read the accompanying preliminary pricing supplement and product supplement for a more complete description of risks relating to the securities.
