The issue price is $1,000, with an underwriting fee of up to $40.75 and minimum proceeds to the issuer of $959.25 per security; the estimated value on the pricing date is expected to be at least $901.00 per security.

The notes pay a contingent coupon of 0.9167% of the $1,000 principal (about 11.00% per annum) only if, on each valuation date, the worst-performing index is at or above 70% of its initial level; otherwise no coupon is paid.

At maturity, if not previously called and the worst index is at or above 70% of its initial level, investors receive $1,000 per note plus any final coupon. If it is below 70%, repayment is reduced one-for-one with the decline in that index, with no minimum, so the principal repayment may be significantly less than $1,000 or zero. Citigroup may redeem the notes early at par plus any due coupon on specified dates, capping future income when performance is favorable.

All payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and the Citigroup Inc. guarantee. The estimated value on the pricing date is expected to be at least $933.00 per note, below the issue price, reflecting structuring, hedging costs and the issuer’s internal funding rate. The product features limited or no secondary market liquidity, complex downside and correlation risks across the three indices, and uncertain U.S. tax treatment, including potential 30% withholding on coupons for certain non-U.S. investors.

If the notes are not called and Dow’s final price is below the downside threshold, investors receive a share delivery amount of Dow stock equal to $1,000 divided by the initial price, exposing them 1-for-1 to any decline from the initial price and potentially losing most or all of principal.

Each security has a $1,000 stated principal amount and pays a 2.50% quarterly contingent coupon (10.00% per annum) only if, on the relevant valuation date, the worst-performing index is at or above 75.00% of its initial level.

The securities are fully and unconditionally guaranteed by Citigroup Inc. The issue price is $1,000 per note, including an underwriting fee of $22.50 (of which $17.50 is selling concession and $5.00 a structuring fee), leaving $977.50 in proceeds to the issuer.
