Hypothetical Payout Profile***

***assumes call premiums equal to the lowest possible call premiums that may be determined on the pricing date

Any positive return on the securities will be limited to the applicable call premium, even if the closing value of the underlying on the applicable call date significantly exceeds the starting value. You will not participate in any appreciation of the underlying beyond the applicable call premium.

If the securities are not automatically called for redemption prior to or at maturity and the ending value is less than the threshold value, you will have 1-to-1 downside exposure to the decrease in the value of the underlying in excess of the buffer amount and will lose some, and possibly up to 90%, of the stated principal amount of your securities at maturity.

On the date of the related preliminary pricing supplement, Citigroup Global Markets Holdings Inc. expects that the estimated value of the securities on the pricing date will be at least $900.00 per security, which will be less than the public offering price. The estimated value of the securities is based on CGMI’s proprietary pricing models and Citigroup Global Markets Holdings Inc.’s internal funding rate. It is not an indication of actual profit to CGMI or other of Citigroup Global Markets Holdings Inc.’s 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 the accompanying preliminary pricing supplement.
