The securities can auto‑redeem on specified valuation dates for the stated principal plus a fixed premium (ranging from 8.25% to 41.25% of principal). If not redeemed, payoff at maturity depends solely on the worst performing underlying, including potential full loss of principal if the worst performing underlying falls below its final barrier.

Citigroup Global Markets Holdings Inc. priced an autocalIable contingent coupon note linked to Meta Platforms, Inc. The securities (stated principal $1,000 per security) were issued on February 27, 2026 with maturity March 29, 2027.

Each security pays a contingent coupon of 0.925% per period (equivalent to 11.10% per annum) when the underlying’s closing value on a valuation date is at or above the coupon barrier of $441.117 (which is 69.00% of the initial underlying value $639.30). If not called, repayment at maturity is $1,000 if the final underlying value is at or above the final barrier; otherwise holders receive an equity delivery equal to an equity ratio of 1.56421 shares per security (or cash in CGMI’s discretion), which may be worth significantly less than principal.

Citigroup Inc. priced callable fixed-rate notes with a stated principal of $1,000 per note, an annual coupon of 4.00%, an original issue date of February 27, 2026 and a maturity date of February 27, 2029. Interest is paid semi‑annually on the 27th of February and August, commencing August 27, 2026. The issuer may call the notes beginning February 27, 2027 on quarterly redemption dates.

The pricing supplement states the notes are intended to qualify as eligible debt under the Federal Reserve’s TLAC rule, meaning holders rank with unsecured creditors for loss absorption in certain resolution scenarios. The notes permit a wholly owned subsidiary to assume Citigroup Inc.’s obligations upon at least 15 business days’ notice, with Citigroup providing a guarantee under specified conditions. Issue price is $1,000 per note and CGMI is the underwriter with an underwriting fee up to $4.00 per note; net proceeds will fund general corporate purposes and hedging.

The securities pay a contingent coupon of 3.025% per period (12.10% per annum) on each contingent coupon payment date only if the closing value of the worst performing underlying on the preceding valuation date is at or above its coupon barrier (70% of the initial underlying value). At maturity, if the worst performing underlying is below its final barrier (65% of initial), repayment is reduced by that underlying's return, potentially resulting in a significant loss of principal. The issuer may call the securities on specified potential redemption dates.

The index applies an excess return deduction (federal funds effective rate plus implicit futures financing cost) and a 0.75% p.a. index fee, and the notes repay stated principal at maturity but returns (coupons or additional payments) depend on index performance and are subject to Citigroup Global Markets Holdings Inc. and Citigroup Inc. credit risk. Specific payment and offering terms will appear in each pricing supplement.

If not autocalled, maturity payoffs depend solely on the worst performing underlying versus its final barrier (75% of initial value), with full loss exposure below that final barrier.

Citigroup Global Markets Holdings Inc. published Product Supplement No. EA-02-12 dated February 25, 2026 setting standardized terms for Medium-Term Senior Notes, Series N, which are senior unsecured securities fully guaranteed by Citigroup Inc.

The supplement explains these securities may be linked to an underlying company, an ETF or an equity index and that payments at maturity depend on the performance of the specified underlying(s) rather than repayment of a fixed principal amount. It highlights key investor considerations: potential loss of principal, reliance on the creditworthiness of Citigroup Global Markets Holdings Inc. and Citigroup Inc., limited secondary-market liquidity, discretion of the calculation agent (CGMI) in valuation and adjustments, and material U.S. federal tax uncertainty. Investors are directed to review the applicable pricing supplement, any underlying supplement and the accompanying prospectus supplement and prospectus for issuance-specific terms.

Citigroup Global Markets Holdings Inc. offers unsecured medium-term senior notes linked to four Nasdaq-100 Futures Edge Volatility Indices published by an affiliate. The notes provide volatility-targeted, futures-based exposure to the Nasdaq-100 via a Citi-managed Underlying Futures Index, may employ up to 500% leverage, and two indices apply a 6% per annum decrement. Payments are unsecured obligations of Citigroup Global Markets Holdings Inc. and are fully and unconditionally guaranteed by Citigroup Inc., so holders bear the credit risk of both issuers. The supplement warns of amplified losses from leverage, decay from weekly rebalancing, underperformance due to implicit financing costs in futures, limited track record (launched April 28, 2025), and discretionary index administration by Citigroup affiliates. Specific issuance terms will appear in a pricing supplement.
