Citigroup Global Markets Holdings Inc. filed a free writing prospectus on November 6, 2026, disclosing preliminary terms for Autocallable Contingent Coupon Equity Linked Securities linked to Boston Scientific Corporation (BSX) with a stated principal amount of $1,000 per security and a maturity date of January 13, 2028.

Key Highlights

  • Issuer and guarantor: Citigroup Global Markets Holdings Inc. is the issuer; Citigroup Inc. is the guarantor.
  • Underlying asset: The securities are linked to Boston Scientific Corporation, ticker "BSX."
  • Contingent coupon rate: 7.50% per annum, paid monthly, only if the closing value of BSX on the related valuation date is at or above 75% of its initial underlying value.
  • Buffer protection: A 25% buffer applies at maturity, with a cash buffer of $250.00 per security; losses beyond 25% are borne by the investor.
  • Automatic early redemption: Securities may be called monthly beginning after six months if BSX closes at or above its initial underlying value on a valuation date, returning $1,000 plus the contingent coupon.
  • Pricing date: December 8, 2026; final valuation date: January 10, 2028; maturity date: January 13, 2028.
  • No exchange listing: According to the filing, "the securities will not be listed on any securities exchange and you may not be able to sell them prior to maturity."

Terms and Risk Profile of the BSX-Linked Securities

According to the filing, the securities carry a stated principal amount of $1,000 per security and are priced on December 8, 2026. The contingent coupon of 7.50% per annum is paid on a monthly basis, but only on valuation dates when the closing value of BSX is greater than or equal to 75% of its initial underlying value, which the filing identifies as the coupon barrier value. Investors are explicitly told: "You are not assured of receiving any contingent coupon."

The filing discloses that if the securities are not automatically redeemed before maturity and the final underlying value of BSX falls below the final buffer value (75% of the initial underlying value), investors will receive a fixed number of underlying shares equal to the equity ratio plus a $250.00 cash buffer per security, rather than the full $1,000 principal. The hypothetical payment table in the filing illustrates that a -50% return on BSX at the final valuation date would result in a payment of $500.00 per security, and a -100% return would yield $250.00 per security. The 25% buffer absorbs losses only up to that threshold.

The filing identifies multiple risk considerations. The securities are described as unsecured debt obligations subject to the credit risk of both the issuer and the guarantor. The filing notes that "the estimated value of the securities on the pricing date is less than the issue price," and that investors will not receive dividends or hold any other shareholder rights with respect to BSX unless and until they receive underlying shares at maturity. The CUSIP is 17334D3K6 and the ISIN is US17334D3K69, as stated in the filing. Registration file numbers cited are 333-293732 and 333-293732-02.
