Form FWP CITIGROUP INC Filed by: CITIGROUP INC

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., has filed preliminary terms for 5 Year Autocallable Market-Linked Securities linked to the Citi Dynamic Asset Selector 5 Excess Return Index (CIISDA5N). These securities offer a potential premium of at least 7.00% per annum if the index meets or exceeds its initial level on annual valuation dates, leading to an automatic early redemption. If not redeemed early, the payment at maturity depends on the index's performance, with a full principal return even if the index declines, but no additional return if it falls below or equals the initial level.
