Citigroup Global Markets Holdings Inc. is offering Medium‑Term Senior Notes, Series N: autocallable contingent coupon equity‑linked securities tied to the S&P 500 Futures 35% Edge Volatility 6% Decrement Index (USD) ER. The securities are unsecured obligations of CGMH and are fully guaranteed by Citigroup Inc. The stated principal amount is $1,000 per security. The pricing date is May 22, 2026 and the issue date is May 28, 2026, with maturity on May 27, 2032 unless redeemed earlier.
