Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., filed a free writing prospectus on November 2, 2026, setting out preliminary terms for 5-year buffered autocallable securities linked to the S&P 500 Futures 40% Intraday Edge Volatility TCA 6% Decrement Index (USD) ER, with a scheduled pricing date of November 24, 2026.

Key Highlights

  • Underlying index: The securities are linked to the S&P 500 Futures 40% Intraday Edge Volatility TCA 6% Decrement Index (USD) ER, ticker SPXI4EV6.
  • Stated principal: $1,000 per security, with a maturity date of November 28, 2031.
  • Autocall premium: 21.00% per annum, accruing monthly; hypothetical redemption at the first annual valuation date (November 26, 2027) would return $1,210.00 per security.
  • Buffer protection: A 15.00% buffer applies at maturity, with a final buffer value set at 85.00% of the initial underlying value.
  • Principal loss risk: If the final underlying value falls below the final buffer value, investors lose 1% of stated principal for every 1% by which depreciation exceeds the buffer percentage; a -100.00% underlying return would produce a hypothetical payment of $150.00.
  • No exchange listing: According to the filing, "the securities will not be listed on any securities exchange" and secondary market sales prior to maturity may result in a loss of principal.
  • CUSIP / ISIN: 17334DV82 / US17334DV822, filed under registration file numbers 333-293732 and 333-293732-02.

Preliminary Terms for Citigroup's SPXI4EV6-Linked Autocallable Securities

Citigroup Global Markets Holdings Inc. filed a free writing prospectus pursuant to Rule 433, dated November 2, 2026, disclosing preliminary terms for 5-year buffered autocallable securities. The issuer is Citigroup Global Markets Holdings Inc., with all payments guaranteed by Citigroup Inc. The filing notes that "all payments on the securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc." The securities carry CUSIP 17334DV82 and ISIN US17334DV822.

The securities are linked to the S&P 500 Futures 40% Intraday Edge Volatility TCA 6% Decrement Index (USD) ER (SPXI4EV6). Beginning approximately one year after issuance, the securities are subject to monthly valuation. If the closing value of the underlying equals or exceeds its initial value on any interim valuation date, the securities are automatically redeemed at $1,000 plus the applicable premium, which accrues at 21.00% per annum. The final valuation date is November 24, 2031, and the maturity date is November 28, 2031. The hypothetical payment at the final valuation date, assuming a 0.00% or greater underlying return and no prior autocall, is $2,050.00 per security.

At maturity, if the final underlying value falls below the initial underlying value but remains at or above 85.00% of it, the investor receives $1,000. Below that buffer, losses are dollar-for-dollar beyond the 15% buffer. The filing identifies several risk considerations, including that "the underlying is highly risky because it may reflect highly leveraged exposure to the Underlying Futures Index and may therefore experience a decline that is many multiples of any decline in the Underlying Futures Index." The filing also states that the estimated value of the securities on the pricing date will be less than the issue price, and that the securities do not pay interest and confer no dividend rights.
