Investors forego dividends and upside in the stock, face limited liquidity, and take the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.. The issue price is $1,000, with an underwriting fee of up to $31 and expected issuer proceeds of $969 per security; the issuer currently expects an estimated value of at least $895 per security based on internal models.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering medium-term senior unsecured autocallable securities linked to the worst performing of the Dow Jones Industrial, Russell 2000® Index and S&P 500® Index, maturing August 5, 2031.

The notes pay no interest. On each observation date, if the worst-performing index is at or above 95.00% of its initial value, the notes are automatically redeemed at $1,000 plus a fixed premium (at least 10.15% on the first date, stepping up to at least 50.75% on the final valuation date). If not called, at maturity investors receive: principal plus premium if the worst index is at or above 95%; principal only if it is between 75.00% and 95%; or a 1-for-1 loss with the index decline if it finishes below 75%, potentially losing the entire investment.

The stated principal is $1,000 per security. The underwriting fee is up to $20.00 per security, leaving issuer proceeds of $980.00. The estimated value on the pricing date is expected to be at least $905.00 per security, below the issue price due to selling, structuring, hedging costs and the issuer’s internal funding rate. Investors do not receive dividends on the indices and face limited liquidity; all payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering medium-term senior Autocallable Buffered Notes linked to the MSCI Emerging Markets Index (MXEF), due July 2028, in $1,000 denominations.

The notes may be automatically redeemed on July 30, 2027 if the index closes at or above the initial level, paying $1,219 per note based on a minimum 21.90% premium; in that case, investors forgo further upside. If held to maturity and the final index level is at or above the initial level, investors receive $1,000 plus index gains multiplied by the 125% upside participation rate. If the index finishes below the initial level but at or above 85% of it (the buffer), investors receive only the $1,000 principal. Below the 85% buffer, principal is reduced using a buffer rate of approximately 117.647%, causing losses that exceed index declines beyond the 15% buffer.

The issue price is $1,000 per security, including a $15 underwriting fee to Citigroup Global Markets Inc., for net proceeds of $985 per note; fiduciary accounts pay $985 with no fee. The issuer expects an estimated value of at least $927.50 per security on the pricing date. Investors do not receive dividends on index constituents and are exposed to both Citigroup credit risk and emerging-market equity volatility. The MSCI Emerging Markets Index last closed at 1,690.70 on July 10, 2026.

Citigroup Global Markets Holdings Inc., fully and unconditionally guaranteed by Citigroup Inc., is offering medium-term senior unsecured Autocallable Contingent Coupon Equity Linked Securities due August 5, 2031. Each security has a stated principal amount and issue price of $1,000, linked to the worst performing of the Nasdaq-100, Russell 2000 and S&P 500 indices.

On each valuation date, investors receive a contingent coupon of at least 0.6667% of principal (equivalent to a contingent coupon rate of approximately at least 8.00% per annum) only if the worst-performing index closes at or above 70.00% of its initial value. Beginning February 1, 2027, if on a potential autocall date that index is at or above its initial value, the notes are automatically redeemed for $1,000 plus the coupon.

If the notes are not called and the final value of the worst-performing index is below 70.00% of its initial value, the maturity payment equals $1,000 + $1,000 × that index’s return, so principal losses track index declines and can reach 100%. Investors receive no dividends or upside participation, face limited liquidity largely through CGMI, bear the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., and confront uncertain U.S. tax treatment with potential 30% withholding for some non-U.S. holders.

Citigroup Global Markets Holdings Inc., fully and unconditionally guaranteed by Citigroup Inc., is offering Medium-Term Senior Notes, Series N, Floating Rate Notes due July 20, 2066 with a stated principal amount of $1,000 per note. The notes pay quarterly interest at a floating rate equal to daily compounded SOFR for the applicable observation period plus a spread of at least 0.10% per annum, subject to a minimum interest rate of 0.00% per annum.

Holders may request early repurchase annually starting July 20, 2029, in minimum aggregates of $10,000, for preset cash amounts per $1,000 note of $970, $980, $990 or $1,000 depending on the repurchase window, plus accrued interest. The notes will not be listed on any securities exchange, may have limited or no secondary-market liquidity, and are subject to risks related to SOFR, potential benchmark replacement and discretionary determinations by an affiliated calculation agent. For U.S. federal income tax purposes, counsel believes the notes should be treated as variable rate debt instruments, and the issuer believes they should qualify as qualified replacement property for certain Section 1042 transactions, subject to conditions.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is issuing callable contingent coupon equity‑linked senior notes with a stated principal of $1,000 per security, maturing July 25, 2029. Returns depend on the worst performer among the Nasdaq‑100, Russell 2000 and S&P 500 indices.

The notes pay a contingent coupon of at least 0.9458% of principal per period (approximately at least 11.35% per year) only when, on the relevant valuation date, the worst index closes at or above 70.00% of its initial level. The issuer may redeem the notes in whole on specified dates at $1,000 plus any due coupon, limiting future income.

If not redeemed, principal is repaid at maturity only if the worst index is at or above 60.00% of its initial level; below that final barrier, repayment falls one‑for‑one with the index decline, down to zero, so investors can lose their entire investment and receive no coupons. The notes are unsecured, subject to Citigroup credit risk, may have limited liquidity, and have an estimated value on the pricing date of at least $937.00 per $1,000 issue price because of structuring, hedging costs and the use of an internal funding rate.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering Step Down Trigger Autocallable Notes linked to the least performing of the Nasdaq-100 Index and the Russell 2000 Index, maturing on or about July 18, 2029. Each note has a $10.00 stated principal amount and may be automatically called quarterly starting one year after issuance if the least performing index is at or above its initial level, or on the final valuation date if it is at or above its 75% downside threshold.

If called, investors receive $10 plus a call return based on at least 11.40% per annum, rising over time; by the final valuation date the example schedule shows a 34.20% total call return (call price $13.420). If the notes are never called and the least performing index finishes below its downside threshold, repayment is $10 × (1 + underlying return of the least performing index), creating full downside exposure and up to a 100% loss of principal.

The notes pay no interest, provide no dividends on index components, will not be listed, and may have limited liquidity. Issue price is $10.00, with $0.25 underwriting discount and $9.75 to the issuer; the estimated value on the trade date is expected to be at least $9.59 per note. Payments depend on the creditworthiness of Citigroup Global Markets Holdings Inc. and Citigroup Inc., and U.S. tax counsel currently views the notes as a prepaid forward contract, subject to uncertainty and potential future tax changes.

Unless earlier called at par plus any due coupon on specified dates from January 2027, the notes mature on July 26, 2029. If the worst index on the final valuation date is at least 60% of its initial level, investors receive full principal; below 60%, repayment is reduced one‑for‑one with the index loss, potentially to zero. Investors do not participate in any index upside or dividends and face the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. The issue price is $1,000, including up to $7.50 in underwriting fees, with an estimated initial value of at least $937.50 and limited expected secondary liquidity.

Each security has a $1,000 stated principal amount and a minimum purchase of $10,000.

The notes may be automatically redeemed on July 26, 2027 if the basket level is at or above its initial level, paying $1,000 plus a premium of at least 19.10% of principal (illustrated as $1,191). If not called, at maturity in July 2028 investors receive: leveraged upside with a 125% upside participation rate when the basket is above its initial level; full principal repayment if the basket is between 90% and 100% of its initial level; and a buffered but increasing loss if it falls below 90%, using a buffer rate of approximately 111.11%. CGMI, acting as principal, receives a $15 underwriting fee per security (issue price $1,000, proceeds to issuer $985), and currently expects an estimated value of at least $916.50 per note. The securities do not pay dividends, may have limited secondary market liquidity, are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., and are expected to be treated as prepaid forward contracts for U.S. federal income tax purposes.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is issuing unsecured, autocallable medium-term senior notes linked to the worst performer of the Nasdaq-100 Index, the S&P 500 Index and the State Street Utilities Select Sector SPDR ETF, in $1,000 denominations with no interest payments.

The notes may be automatically redeemed on scheduled valuation dates if the worst underlying is at or above its initial level, paying $1,000 plus a fixed premium that is at least 12.20% initially and rises to at least 36.60% by July 16, 2029. If not called, maturity payment depends solely on the worst underlying: principal plus premium if it finishes at or above 80% of its initial value; principal only if between 60% and 80%; and a 1-for-1 loss below 60%, potentially up to a total loss of principal.

All payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. The estimated value on the pricing date is expected to be at least $918.50 per $1,000 note, below the issue price, reflecting selling, structuring and hedging costs and use of an internal funding rate. Liquidity may be limited, and investors forgo dividends and other rights on the underlyings.

Citigroup Global Markets Holdings Inc., fully and unconditionally guaranteed by Citigroup Inc., is offering Autocallable Buffered Notes linked to the MSCI Emerging Markets Index (MXEF). Each medium-term senior note of Series N has a stated principal amount of $1,000 per security.

The notes may be automatically redeemed on August 13, 2027 if MXEF closes at or above its initial value, paying $1,000 plus a premium of at least 18.15%. If not redeemed, at the August 2028 final valuation date investors receive $1,000 plus the greater of a 36.30% premium or index return when MXEF finishes at or above its initial level, only principal back if MXEF ends between 85% and 100% of its initial level, and buffered downside if MXEF falls more than the 15.00% buffer, with losses amplified by a buffer rate of about 117.647%. The issue price is $1,000, including a $15 underwriting fee, with expected estimated value of at least $925.50 per security.

If the final index level is below the initial but at or above 85.00% of the initial level (a 15.00% buffer), principal is repaid. Below 85.00%, repayment is reduced using a buffer rate of approximately 117.647%, so losses exceed index declines beyond the buffer. The issue price is $1,000 with a $15.00 underwriting fee and an estimated value of at least $926.00 per security, and the notes are exposed to Citigroup credit risk, emerging-markets equity volatility and complex U.S. tax treatment as a prepaid forward contract.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering unsecured Medium‑Term Senior Notes linked to the worst of the Nasdaq‑100, Russell 2000 and S&P 500 indices, maturing July 26, 2029.

The securities pay a contingent quarterly coupon of at least 3.1625% of principal (12.65% annualized, set on the pricing date) only if, on the relevant valuation date, the worst‑performing index closes at or above 70% of its initial level. Missed coupons are not paid later. At maturity, if not called and the worst index is at or above 70% of its initial level, investors receive $1,000 per note plus any final coupon; otherwise repayment is $1,000 plus $1,000 times the index return, exposing principal one‑for‑one to downside and potentially to zero.

The issuer may redeem the notes in whole on specified dates at $1,000 plus the related coupon, capping future income. The estimated value on the pricing date is expected to be at least $938.50 per note, below the $1,000 issue price due to selling, structuring, hedging costs and funding assumptions. The notes carry the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., offer no index upside or dividends, may have limited secondary liquidity, and involve complex U.S. tax and withholding considerations, including potential 30% withholding for certain non‑U.S. holders.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering callable equity‑linked senior notes tied to the worst performing of the Nasdaq‑100, Russell 2000 and S&P 500 indexes. Each security has a $1,000 principal amount and pays monthly coupons at an annualized rate of approximately at least 13.15%.

The notes mature on July 16, 2027 but may be redeemed at the issuer’s option on monthly dates from January through June 2027 for $1,000 plus the coupon. If not called and a “knock‑in event” occurs—any index closing below 70.00% of its initial level on any day—principal is reduced one‑for‑one with the worst index’s loss, potentially to zero. Investors also face credit risk of the issuer and guarantor, limited liquidity, and complex, uncertain U.S. tax treatment, and the notes’ estimated value on the pricing date (at least $942.50 per security) will be below the $1,000 issue price.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering autocallable buffered notes linked to an equally weighted basket of Bank of America, Capital One Financial, Morgan Stanley and Wells Fargo common stock, maturing in August 2028 with a $1,000 stated principal amount per note.

The notes may be automatically redeemed on August 13, 2027 if the basket is at or above its initial level, paying $1,186.50 per note (an 18.65% premium). If held to maturity and the basket is above its initial level, investors receive principal plus 125% of the basket’s gain; if it is between 90 and 100, principal is returned; below 90, losses accelerate so holders can lose most or all of principal.

Holders forgo dividends on the underlying stocks and take the credit risk of the issuer and guarantor. The public issue price is $1,000, including a $15 underwriting fee, while the estimated value is expected to be at least $914.50 per note due to fees, hedging costs and Citigroup’s internal funding rate. The notes involve complex market, liquidity and tax considerations, including prepaid forward treatment and potential Section 871(m) implications for non-U.S. investors.

Each unsecured note has a $1,000 principal amount, matures on July 12, 2029, and is linked to the worst-performing of Amazon, Microsoft, Alphabet and Meta.

The notes pay a monthly contingent coupon at 12.00% per annum only if the lowest-performing stock on each calculation day is at or above 50% of its starting value, with a memory feature for missed coupons. From October 2026 to June 2029, the notes auto-call at par plus coupons if that lowest stock is at or above 95% of its start. If not called, principal is fully repaid only if the worst stock on the final calculation day is at or above 50% of its start; otherwise repayment equals $1,000 times its performance factor, so losses can reach 100%. Investors forgo dividends, face issuer and guarantor credit risk, limited liquidity and complex tax treatment. The estimated value is $947.70 per note versus the $1,000 public offering price, reflecting selling, structuring and hedging costs and the issuer’s internal funding rate.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering $10,000,000 of Autocallable Phoenix Securities linked to Invesco QQQ Trust, Series 1, maturing on July 14, 2027.

The notes pay a 1.4667% contingent coupon per period only when QQQ’s closing price is at or above the $640.296 coupon barrier (90.00% of the $711.44 initial share price), with a memory feature for previously missed coupons. If on any interim valuation date QQQ closes at or above the initial share price, the notes are automatically redeemed at $1,000 per security plus the applicable coupon.

If not called and the final QQQ price is at or above the same $640.296 final barrier, investors receive $1,000 plus the final coupon, including any unpaid prior coupons. If the final price is below the barrier, repayment follows a buffered formula with a 10.00% downside buffer but can result in substantial, up to total, loss of principal and no coupon at maturity. The issue price is $1,000 per security (or $999 for fiduciary accounts), including a $1.00 underwriting fee; estimated value on the pricing date is $1,000.90. The securities carry Citigroup credit risk, are not bank deposits or FDIC-insured, and involve complex U.S. tax and potential 30% withholding treatment, especially for non-U.S. investors.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering Barrier Securities due July 14, 2036, each with a $1,000 stated principal amount, linked to the worst performer of the Nasdaq-100 Futures Excess Return Index and the S&P 500 Futures Excess Return Index. Initial index values are 782.0496 and 603.95, with downside barriers at 60% of each initial level.

At maturity, if the worst-performing index ends above its initial value, investors receive $1,000 plus 416.00% of that index’s gain; if it finishes between its initial value and the barrier, they receive $1,000; if it finishes below the barrier, they incur one-for-one losses on the downside, potentially losing their entire principal. The total offering is $250,000.00, with an underwriting fee of $12.00 per security and issuer proceeds of $988.00 per security. The initial estimated value is $974.50 per security, reflecting Citigroup Global Markets Inc.’s internal models and funding rate, and investors receive no dividends from the underlying indices. The notes involve complex risks, including issuer and guarantor credit risk, exposure to futures-based excess return indices and U.S. tax uncertainty (treated as prepaid forward contracts under current counsel opinion).

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering $1,000 denomination autocallable contingent coupon equity-linked securities linked to the Nasdaq-100 Futures 35% Edge Volatility 6% Decrement Index ER, maturing on July 19, 2033.

The notes pay a monthly contingent coupon of 1.5625% of principal (about 18.75% per year) only if the index is at or above the coupon barrier of 1,287.368 (70% of the initial value 1,839.097). Principal is protected at maturity only if the final index level stays at or above the final barrier of 1,103.458 (60% of initial); otherwise repayment is reduced one-for-one with the index loss and can fall to zero.

From July 14, 2027, if the index closes at or above its initial level on any trading day, the notes are automatically redeemed at $1,000 plus any due coupon, capping further income. The issue price is $1,000 but the estimated value is $893.70, reflecting hedging costs, fees and the issuer’s funding rate. The complex underlying uses leverage, a 35% volatility target and a 6% per annum decrement, which can cause persistent underperformance versus the Nasdaq‑100 Index. Citigroup may also redeem early following certain changes to referenced volatility indices at a model-determined fair value, which may be below principal.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering Dual Directional Buffer Securities linked to the S&P 500® Index under its Medium-Term Senior Notes, Series N. Each security has a $1,000 stated principal amount and matures on November 4, 2027.

At maturity, if the S&P 500 final value is at or above its initial level, holders receive $1,000 plus a digital return of at least $46. If the index has declined but remains at or above 95.40% of the initial level, holders receive the digital return plus 1-to-1 upside on the absolute decline. If the index falls between 95.40% and 80.00% of the initial level, the payout is $1,000 plus the absolute decline, without the digital return. Below 80.00%, investors are exposed to losses beyond a 20.00% buffer, losing 1% of principal for each additional 1% drop.

The issue price is $1,000 per security, including an underwriting fee of up to $20, leaving $980 in proceeds to the issuer; the estimated value on the pricing date is expected to be at least $922.50 per security. Holders do not receive dividends on the S&P 500. The product is characterized for tax purposes on a reasonable basis as a prepaid forward contract, though there is substantial uncertainty, including potential treatment as debt with original issue discount and possible Section 871(m) withholding for certain non‑U.S. investors.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering $836,000.00 of unsecured market-linked securities maturing July 13, 2028. Each $1,000 security pays at maturity the principal plus any appreciation of the worst performer of the Russell 2000 Index and S&P 500 Index, with a 100% upside participation rate.

The return is capped at a maximum of $163.00 per security (16.30% of principal); if the worst index is flat or lower, only the $1,000 principal is repaid and no interest is ever paid. Investors forgo all dividends on the indices. The notes are unsecured and subject to Citigroup credit risk, may have little or no secondary market, have an estimated value of $978.00 per security below the issue price, and are expected to be treated as contingent payment debt instruments for U.S. federal income tax purposes.

Citigroup Global Markets Holdings Inc., guaranteed by Citigroup Inc., is offering callable contingent coupon equity-linked senior notes tied to the worst performer of the Nasdaq-100 Index®, Russell 2000® Index and S&P 500® Index, with a stated principal amount of $1,000 per security.

These notes can pay a contingent coupon of at least 1.0083% of principal per valuation period (approximately at least 12.10% annualized) only if the worst-performing index on the prior valuation date is at or above 70.00% of its initial level; otherwise no coupon is paid. At maturity, if not previously redeemed and the worst-performing index is at or above 70.00% of its initial level, investors receive $1,000 per note; if it is below that barrier, repayment is $1,000 plus $1,000 times the index return, so principal declines 1% for each 1% drop in the worst index, with no minimum repayment and potential loss of all invested principal.

The issuer may redeem the notes in whole on specified dates at $1,000 plus any due coupon, limiting future income. Credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., limited expected liquidity, an estimated value on the pricing date expected to be at least $935 per note (below the $1,000 issue price), complex U.S. tax treatment and potential withholding for non‑U.S. holders are highlighted as key risks.

Citigroup Global Markets Holdings Inc. is offering $3,902,000 of Buffered Digital S&P 500® Index-Linked Notes due October 27, 2027, fully and unconditionally guaranteed by Citigroup Inc.

The notes pay no interest and repay no fixed principal. For each $1,000 note, if the S&P 500® Index final level on October 25, 2027 is at least 90.00% of the initial level of 7,543.64, holders receive a fixed $1,128.50 (112.85% of principal), a contingent return of 12.85%. If the index falls more than the 10.00% threshold, principal loss accelerates at approximately 1.1111% for every 1% decline beyond the threshold, down to potential total loss.

Investors forgo any upside above the capped 12.85% return, as well as all dividends on S&P 500® stocks and any interim interest. The notes are unsecured senior obligations subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., will not be listed on any exchange, may have little or no secondary market, and have an estimated value on the trade date that is lower than the issue price due to selling, structuring and hedging costs and the use of an internal funding rate.

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., is offering autocallable contingent coupon equity‑linked medium‑term senior notes tied to the worst performing of the Nasdaq‑100, Russell 2000 and S&P 500 indices. Each security has a $1,000 stated principal amount.

If not called, maturity in July 2029 returns $1,000 only if the worst index finishes at or above 70% of its initial level; otherwise repayment falls one‑for‑one with that index, allowing for up to 100% loss of principal. The issue price is $1,000, including up to $29.50 in underwriting fees, while the issuer expects the estimated value on the pricing date to be at least $913.50 per security, and all payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.
