The underlying index itself is highly complex, employing up to 500% leveraged exposure, a 40% volatility target and a 6% per annum decrement, and has historically underperformed the S&P 500 Index.

The estimated value on the pricing date is expected to be at least $924.50 per security, below the $1,000 issue price, reflecting structuring and hedging costs.

The notes may be automatically called on specified dates if Intel is at or above the initial value of $81.88, in which case investors receive $1,000 plus applicable coupons.

The notes pay a fixed monthly coupon of 0.6042% of principal (about 7.25% per annum) until maturity or automatic early redemption. Starting July 28, 2027, if on any potential autocall date the index closes at or above its initial value of 9,348.07, the notes are called at $1,000 plus the coupon, limiting further income.

At maturity in 2031, if not called, investors receive principal plus the final coupon if a downside event does not occur. The downside threshold is 7,945.860 (85% of the initial index), with a 15% buffer. If the index is below this level, repayment is reduced: investors lose 1% of principal for each 1% decline beyond the buffer, as illustrated by hypothetical payouts down to about $156 for a 100% index loss.

The issue price is $1,000 per note, including up to $45 in underwriting fees (proceeds to issuer $955), with a total offering of $196,000. Citigroup estimates the value at $896.50 per note at pricing, below the issue price, reflecting hedging and distribution costs. The underlying index is complex, uses up to 500% leverage, a 40% volatility target, and a 6% per annum decrement, and the issuer highlights that the index and the notes involve significant risks and may materially underperform the S&P 500.

If, on any trading day from August 2, 2027 to the final valuation date, the index closes at or above its initial value, the notes are automatically called at par, plus any due coupon if the trigger day is also a valuation date.

If the notes are not called, at maturity investors receive $1,000 per note only if the final index level is at or above the final barrier of 807.667 (50% of initial). Below this barrier, repayment falls linearly with index performance, and the loss can be up to the entire principal with no final coupon. The total offering is $1,201,000 in principal; the issue price is $1,000 per security, including a $50 underwriting fee, for net proceeds of $950 to the issuer.

At maturity, if not called, investors receive $1,000 per note if the final index level is at or above the final buffer value of 7,945.860 (85% of initial). Below this level, principal is reduced according to index losses beyond the 15% buffer, with potential for substantial loss of capital and no coupons.

The total offering size is $3,793,000, with an underwriting fee of $50 per security and proceeds to the issuer of $950 per security. The initial estimated value is $891 per security, below issue price, and liquidity is expected to be limited, with CGMI the likely market maker. The underlying index is issuer-designed, highly complex, uses up to 500% leverage, embeds a 6% per annum decrement, and has limited live history, and the tax treatment is uncertain.

The issue price is $1,000 per security, including an underwriting fee of up to $19.50, for minimum proceeds of $980.50 per security to the issuer. Citigroup Global Markets Inc. estimates the value of each security at $966.00 on the pricing date, based on proprietary models and an internal funding rate.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering autocallable contingent coupon equity-linked securities tied to the S&P 500 Futures 40% Intraday Edge Volatility TCA 6% Decrement Index (USD) ER, maturing on July 31, 2031, with a stated principal amount of $1,000 per security.

The notes pay a 0.9375% contingent coupon per period (11.25% per annum) only when the index closes at or above the coupon barrier of 6,076.246 (65% of the initial level). Principal is protected only to a 15% buffer: if the final index level is below the final buffer value of 7,945.860, repayment is reduced 1% for each 1% decline beyond the buffer. The notes may be automatically called from July 2027 onward if the index is at or above its initial level, limiting upside. The initial index level is 9,348.07. Issue price is $1,000, but the estimated value is $877.70, reflecting structuring and hedging costs. The complex underlying index uses leverage up to 500%, a 40% volatility target and a 6% annual decrement, and may significantly underperform the S&P 500 Index; investors also face early redemption on a material modification event, tax uncertainty and the risk of receiving no coupons and less than principal at maturity.

The notes pay a contingent coupon of 1.15% per period (13.80% per annum) only if on the relevant valuation date the index is at or above the coupon barrier value of 7,478.456 (80% of the 9,348.07 initial level. Missed coupons can be “made up” if the barrier is later met. Beginning July 28, 2027, on specified potential autocall dates, if the index is at or above its initial level, the notes are automatically redeemed at $1,000 plus the coupon and any unpaid coupons.

If not called, the maturity payoff depends on the final index level. If the final value is at or above the final buffer value of 7,945.860 (85% of initial), investors receive $1,000 plus any due coupon. If it is below the buffer, principal is reduced 1% for each 1% decline beyond the 15% buffer, with potential for substantial loss. The estimated value is $878.40 per $1,000, below the issue price, reflecting structuring and hedging costs. The complex, leveraged index (up to 500% exposure, 6% per annum decrement and notional costs) can materially underperform the S&P 500® and is subject to path-dependent “decay,” as well as significant tax and withholding uncertainties, particularly for non-U.S. investors.

Citigroup may redeem the notes in whole on specified quarterly dates from August 2, 2027 through July 3, 2031, paying $1,000 plus a preset premium that steps up from 11.5000% to 56.5417% of principal. If not redeemed, maturity payment depends on index performance: for gains, investors receive principal plus a leveraged upside return at a 200.00% upside participation rate; for moderate losses down to a barrier, they receive principal plus the absolute value of the negative return; for declines beyond a 60% barrier (final barrier value 356.472 versus initial value 594.12), principal is reduced 1‑for‑1 with the index and can be fully lost.

The issue price is $1,000 per note, including up to $41.25 underwriting fee and estimated value of $913.70. The notes pay no dividends, are unsecured obligations subject to Citigroup credit risk, may be illiquid, and are expected to be treated as prepaid forward contracts for U.S. tax purposes.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is issuing autocallable securities linked to the worst performing of the S&P 500 Index and Russell 2000 Index, each with a $1,000 stated principal amount and maturing on August 2, 2029 unless called earlier. Initial index values are 7,428.78 for the S&P 500 and 2,953.800 for the Russell 2000, with trigger values set at 80% of those levels. If on the first valuation date in 2027 the worst performer is at or above its initial value, investors receive $1,125 per security and the notes are redeemed; if only the 2029 test qualifies, the payout is $1,350.

If it falls below the trigger, repayment is $1,000 plus the index return of the worst-performing index, exposing investors to full downside below the trigger and potentially a total loss of principal. The issue price is $1,000, including up to a $32 underwriting fee, while the estimated value is $959.50 based on Citi’s models.

Each $1,000 security may pay a quarterly contingent coupon of 2.675% (10.70% per annum) if, on the relevant valuation date, the worst performing index is at or above its coupon barrier (70% of its initial level).

Otherwise, the payoff is $1,000 plus $1,000 times the worst index return, exposing investors to losses up to 100% of principal.

On specified autocall dates, if the worst-performing index is at or above its initial level, the notes are redeemed early at $1,000 plus the coupon.

If not called and the worst-performing index finishes below its final barrier, repayment of principal is reduced 1-for-1 with the index loss, down to zero.

The underlying index is described as highly risky, using up to 500% leveraged exposure to S&P 500 futures, a 35% volatility target, and a 6% per annum decrement that systematically drags performance and is expected to make it underperform the S&P 500 Index. Investors face Citigroup Global Markets Holdings Inc. and Citigroup Inc. credit risk, limited or no secondary market liquidity, complex and uncertain U.S. tax treatment (including potential debt treatment and Section 871(m) considerations), and substantial risks highlighted in extensive risk factor disclosure.

Investors forgo dividends and upside in NVIDIA, face full issuer and guarantor credit risk, an illiquid secondary market, and an initial estimated value of $941.10 per $1,000, below issue price due to selling, hedging costs and internal funding assumptions.

Citigroup Global Markets Holdings Inc., a wholly owned subsidiary of Citigroup Inc., is offering fixed rate notes due September 3, 2027, fully and unconditionally guaranteed by Citigroup Inc.

The notes are automatically redeemed at $1,000 plus coupon on specified autocall dates if Meta is at or above its initial value.

The securities are unsecured and subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. The issue price is $1,000 per note, including a $40 underwriting fee, versus an estimated value of $943.60, and may have limited or no secondary market liquidity.

The notes feature an autocall on July 28, 2027: if the worst performing index is at or above its initial level, investors receive $1,096 per $1,000 note (principal plus a $96 premium) and the notes are redeemed.

At maturity, investors receive $1,000 per note only if the worst-performing stock is at or above its 50% final barrier. Otherwise, repayment is reduced one-for-one with the decline of that stock, down to zero, resulting in potential total loss of principal and no final coupon.

At maturity, holders receive $1,000 plus a return amount that is positive only if the Dow Jones Industrial Average closes higher on the May 29, 2029 valuation date than on the August 26, 2026 pricing date. The upside participation rate is 100%, but the return is capped by a maximum return at maturity of $175 per security (17.50%), so the payment per security will not exceed $1,175. If the index is flat or lower, investors receive only the $1,000 principal, with no additional return.

The securities do not provide dividends or voting rights on the underlying index components and may have limited or no liquidity. An underwriting fee of up to $22.50 per $1,000 security is paid to Citigroup Global Markets Inc., leaving minimum per-security proceeds of $977.50 to the issuer. The estimated value on the pricing date is expected to be at least $911.00 per security, below the issue price, reflecting selling, structuring and hedging costs and the issuer’s internal funding rate.
