Citigroup Inc 424B Filings

CITIGROUP INC (C), through Citigroup Global Markets Holdings Inc., is offering callable contingent coupon equity-linked medium-term senior notes with a $1,000 stated principal amount per security, linked to the worst performer of the Nasdaq-100 Index, the Russell 2000 Index and the VanEck Semiconductor ETF, and maturing on September 9, 2031.

The notes pay a contingent coupon of at least 1.2333% of principal per observation period (approximately 14.80% per annum) only if, on the relevant valuation date, the worst-performing underlying is at or above 60% of its initial value; otherwise no coupon is paid. If held to maturity and not called, investors receive full principal only if the worst-performing underlying is at or above its 60% final barrier; otherwise, repayment is reduced one-for-one with the decline in that underlying, down to a possible zero. Citigroup may redeem the notes early on specified dates at $1,000 plus any due coupon, and all payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and the Citigroup Inc. guarantee.

CITIGROUP INC (C), via Citigroup Global Markets Holdings Inc., is offering unsecured, principal-at-risk securities linked to the 30-year GBP SONIA ICE swap rate (SONIA CMS30), fully and unconditionally guaranteed by Citigroup Inc. Each security has a £1,000 stated principal amount and matures on November 30, 2026, with valuation on November 26, 2026.

At maturity, investors receive: the maximum payment £1,270.5923903 per £1,000 if the SONIA CMS30 rate is at or above the 5.069% strike, or a reduced amount that declines linearly as the rate falls below the strike, based on an OTM strike width of 0.50%, but not less than the minimum £270.5923903. Examples show potential returns from about +27.06% to about -72.94%, so a significant loss of principal is possible.

The issue price is 100% of principal, with total proceeds of £10,618,000 and no underwriting fee; Citigroup Global Markets Inc. acts as principal and may profit from hedging. The estimated value is £992.56 per security, below the issue price. The notes are cleared through Euroclear and Clearstream, carry complex tax treatment, and include ERISA and FATCA considerations.

Citigroup Inc. (C) is offering $1,004,000 of Autocallable Contingent Coupon Equity Linked Securities, issued by Citigroup Global Markets Holdings Inc. and fully guaranteed by Citigroup Inc., linked to the Nasdaq-100 Futures 35% Edge Volatility 6% Decrement Index ER, maturing September 5, 2036 unless called earlier.

The notes pay a monthly 1.175% contingent coupon (14.10% per annum) only if the index is at or above the coupon barrier of 1,055.441 (60% of the 1,759.068 initial value; 50% final barrier 879.534). From August 31, 2027, the notes are automatically redeemed at $1,000 per note if the index closes at or above its initial value on any trading day, which can cap total coupons.

If not called, at maturity investors receive $1,000 per note only if the final index value is at least the final barrier; otherwise payoff is $1,000 × (1 + index return), exposing principal to full downside below that level and possibly to total loss, with no coupon. The issue price is $1,000 per note, including a $50 underwriting fee; issuer proceeds are $950 per note. The estimated value is $864.30 per note, below the issue price, reflecting structuring and hedging costs. U.S. tax treatment is uncertain and non-U.S. holders may face 30% withholding on coupons; the notes are treated as complex prepaid forward contracts with associated coupon income.

CITIGROUP INC (C), through Citigroup Global Markets Holdings Inc., is offering buffered autocallable securities linked to the S&P 500 Futures 40% Intraday Edge Volatility TCA 6% Decrement Index (USD) ER, with a stated principal amount of $1,000 per security and final maturity on August 29, 2031, unless automatically redeemed earlier.

The notes may be automatically redeemed on scheduled valuation dates starting August 27, 2027 if the index closing value is at or above the initial level of 9,823.75, paying $1,000 plus a fixed premium that steps up from 20% to 100% of principal by the final valuation date. If held to maturity and not called, investors receive: $1,000 plus the final premium if the index is at or above the initial level; $1,000 if the index is between the initial level and the 15% downside buffer; or a reduced amount with 1‑for‑1 loss beyond the buffer if the index finishes below the buffer level of 8,350.188.

The issue price is $1,000 per security, including up to $45 in underwriting fees (total offering $3,446,000), with estimated value of $880.20 per security based on Citigroup Global Markets Inc.’s models. The complex underlying index uses leveraged, volatility‑targeted S&P 500 futures exposure with a 6% annual decrement and notional costs, and may significantly underperform the S&P 500 Index. The securities are unsecured obligations of the issuer, fully and unconditionally guaranteed by Citigroup Inc., and involve significant market, structural, liquidity and tax risks.

CITIGROUP INC (C), through Citigroup Global Markets Holdings Inc., is issuing unsecured, guaranteed callable contingent coupon equity-linked securities maturing August 30, 2029, linked to the worst performing of the Nasdaq-100 Index®, Russell 2000® Index and S&P 500® Index.

The notes have a stated principal of $1,000 per security and pay a monthly contingent coupon of 0.9167% (about 11.00% per annum) only if, on the relevant valuation date, the worst-performing index is at or above its coupon barrier of 70% of its initial value. Principal is protected only if, on the final valuation date, the worst-performing index is at or above its final barrier of 60% of its initial value; otherwise, repayment is reduced 1% for every 1% decline in that index, potentially to zero.

Citigroup may redeem the notes early on specified dates at $1,000 plus any due coupon, limiting future income if called. The total offering is $500,000 (issue price $1,000, underwriting fee up to $2.50, proceeds to issuer $997.50 per note), and the estimated value at pricing is $985 based on internal models. Investors face equity, correlation, liquidity, tax and credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., and do not receive dividends or upside participation in the indices.

The stated principal amount is $1,000 per security, with total issuance of $1,297,000. Early redemption can occur on annual valuation dates if the worst performing index closes at or above its initial value, paying $1,000 plus a fixed premium that steps up from 9% in 2027 to 45% in 2031. If held to maturity and not called, investors receive $1,000 plus the 45% premium if the worst index is at or above its initial value, $1,000 if it is below initial but at or above its 65% barrier, and otherwise lose 1% of principal for each 1% decline in the worst index from its initial level.

All payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. The securities lack dividends, upside beyond fixed premiums, and may have limited or no secondary market. The estimated value on the pricing date is $951.10 per security, below the $1,000 issue price, reflecting selling, structuring and hedging costs.

Each security has a $1,000 stated principal and pays a quarterly contingent coupon of at least 3.3125% (annualized at least 13.25%) only if, on the prior valuation date, the worst-performing underlying is at or above 60% of its initial value. If not, that coupon is skipped. At maturity, if not previously called and the worst-performing underlying is at or above its 60% final barrier, investors receive $1,000 plus any final coupon; otherwise they receive $1,000 plus the negative return of the worst-performing underlying, risking up to a 100% loss of principal. Citigroup may redeem the notes early on specified dates at $1,000 plus any due coupon. The estimated value on the pricing date is expected to be at least $904 per $1,000, below issue price, reflecting structuring and hedging costs.

CITIGROUP INC (C), through subsidiary Citigroup Global Markets Holdings Inc., is offering unsecured Medium-Term Senior Notes, Series N, in the form of Autocallable Contingent Coupon Equity Linked Securities due April 4, 2028, linked to the worst performing of the Nasdaq-100 Index, the Russell 2000 Index and the S&P 500 Index, and fully and unconditionally guaranteed by Citigroup Inc.

The notes have a stated principal amount of $1,000 per security and pay a contingent coupon of 0.9792% per period (about 11.75% per annum) only if, on the relevant valuation date, the worst-performing index is at or above 80% of its initial value (the coupon barrier); missed coupons can be paid later if the barrier is subsequently met. The securities are subject to automatic early redemption on specified potential autocall dates if the worst-performing index is at or above its initial value, in which case investors receive $1,000 plus the due contingent coupon and any previously unpaid coupons.

If the notes are not called and on the final valuation date the worst-performing index is at or above 80% of its initial value, investors receive $1,000 per security (plus any final coupon). If it is below 80%, repayment is $1,000 plus $1,000 times the index return of the worst-performing index, exposing investors to losses up to 100% of principal and with no contingent coupon at maturity in that case. The issue price is $1,000, with an underwriting fee of up to $10 and minimum proceeds to the issuer of $990 per security; the issuer expects an initial estimated value of at least $931.50 per security, reflecting selling, structuring and hedging costs and its internal funding rate.

CITIGROUP INC (C), through Citigroup Global Markets Holdings Inc., is offering callable equity linked securities tied to Monolithic Power Systems, Inc. (MPWR), fully and unconditionally guaranteed by Citigroup Inc. Each security has a $5,000 stated principal amount and pays a quarterly coupon of 3.1375% of principal (equivalent to 12.55% per annum), until redeemed or at maturity.

The securities price on August 28, 2026, are issued on September 2, 2026, and, unless earlier redeemed, mature on August 31, 2028, with a valuation date of August 28, 2028. Citigroup may redeem them in whole on specified coupon dates in 2027 and 2028 at $5,000 plus the coupon. If not redeemed, investors receive principal back only if a downside event does not occur; otherwise they receive MPWR shares (or cash) worth the equity ratio times the final share price, which may be substantially less than principal.

The downside event occurs if the final MPWR value is below 40% of its initial value. Underwriting economics per security are: $5,000.00 issue price, $92.50 maximum underwriting fee and $4,907.50 proceeds to the issuer, with an initial estimated value of at least $4,585.00 based on Citigroup Global Markets Inc.’s proprietary models. The product carries significant market, credit and tax risks, including potential loss of principal.

Each security has a $1,000 stated principal amount, no interest, and all payments are subject to the credit risk of both entities.

The notes can be automatically redeemed on September 10, 2027 if NVIDIA’s closing value is at or above its initial value, paying $1,214.50 per security (principal plus a 21.45% premium). If not redeemed, at maturity investors participate in upside at a 125% upside participation rate or receive principal back if NVIDIA is down but not below an 85% final buffer level. If NVIDIA falls more than the 15% buffer, principal is lost 1-for-1 beyond that threshold. The estimated value on the pricing date is expected to be at least $928 per security, below the $1,000 issue price, reflecting selling, structuring and hedging costs.

Citigroup Inc. (C), via Citigroup Global Markets Holdings Inc., is offering Autocallable Contingent Coupon Equity Linked Securities linked to the Nasdaq-100 Futures 35% Edge Volatility 6% Decrement™ Index ER, with a stated principal of $1,000 per security and an aggregate offering of $4,398,000.

The notes pay a monthly contingent coupon of 1.5833% of principal (about 19.00% per year) only if the index is at or above the coupon barrier of 1,201.660 (70% of the 1,716.657 initial value) on the prior valuation date. From August 30, 2027, if the index closes at or above its initial value on any trading day, the notes are automatically redeemed at $1,000 per security (plus the coupon only if that day is also a valuation date).

If not called, at maturity in 2033 investors receive $1,000 per security only if the final index value is at or above the final barrier of 1,029.994 (60% of initial). Below this barrier, repayment falls linearly with the index and can drop to zero, and no coupon is paid. The estimated value is $917.80 per security, below the $1,000 issue price, reflecting dealer pricing and fees. The complex, volatility-targeted index (35% target, leverage up to 500% plus a 6% annual decrement) has limited history and has historically underperformed the Nasdaq‑100 Index® over 1–5 year periods.

Each security has a $10 stated principal and provides 200% participation in index gains, capped by a maximum return at maturity of $2.71 per security (27.10%).

If the index ends between 90% and 100% of its initial level of 3,255.12, investors receive $10. If it falls below the final buffer value of 2,929.608 (10% buffer), principal is reduced according to a buffer rate of about 111.1111%, leading to losses greater than the index decline beyond 10%. The estimated value at pricing was $9.886 per security, below the $10 issue price, and the notes are fully and unconditionally guaranteed by Citigroup Inc.

CITIGROUP INC (C), through Citigroup Global Markets Holdings Inc., is offering unsecured, index-linked notes guaranteed by Citigroup Inc. Each security has a $1,000 stated principal amount, total public offering price of $7,866,000, pricing on August 25, 2026 and maturing August 29, 2030. The notes are linked to the Nasdaq-100 Index® and the S&P 500® Index and may be automatically called quarterly if the lowest-performing index on a call date is at or above its starting value, paying $1,000 plus a fixed call premium of 10.500%–42.000%, depending on the call date.

If never called and the lowest-performing index finishes below 75% of its starting value (its threshold value), principal is reduced 1-for-1 with the index loss, down to zero; there is no minimum repayment and no interest is paid. The estimated value is $968.60 per $1,000, below the public price, reflecting selling, structuring and hedging costs and Citigroup’s internal funding rate. Investors face Citigroup Global Markets Holdings Inc. and Citigroup Inc. credit risk, limited or no secondary market, complex payoff tied only to the worst-performing index, and uncertain U.S. tax treatment described as a prepaid forward contract.

CITIGROUP INC (C), through Citigroup Global Markets Holdings Inc., is offering Geared Buffer Securities linked to the S&P 500® Index, maturing on August 30, 2028.

If the S&P 500® final value is at or below the initial value but not below 90% of it, investors receive the full $10 principal. Below the 10% buffer, principal is reduced using a buffer rate of approximately 111.1111%, so losses accelerate beyond the buffer. The initial index level is 7,677.28 and the final buffer value is 6,909.552. Total proceeds are $6,771,500, with no underwriting fee, and all payments are fully and unconditionally guaranteed by Citigroup Inc. The estimated value is $9.94 per security, based on Citigroup Global Markets Inc.’s proprietary models. The securities are treated as prepaid forward contracts for U.S. federal income tax purposes, subject to uncertainty and potential future tax law changes, and do not pay dividends or convey any rights in the underlying index.

CITIGROUP INC (C), via Citigroup Global Markets Holdings Inc., is offering $4,760,000 aggregate stated principal amount of Buffered Equity Index Basket-Linked Notes due February 24, 2028, fully and unconditionally guaranteed by Citigroup Inc.

The notes are linked to a non-U.S. equity basket with fixed weights: EURO STOXX 50® 40%, TOPIX® 25%, FTSE® 100 17%, Swiss Market Index® 11% and S&P/ASX 200 7%, with an initial basket level of 100.00. Investors receive 180% upside participation in the basket return, capped at a cap level of 112.84%, giving a maximum settlement amount of $1,231.12 and a maximum return of 23.112% per $1,000 note.

The structure includes a 12.50% buffer: if the basket decline is within this range, principal is repaid; beyond it, investors lose about 1.1429% of principal for every additional 1% drop and can lose their entire investment. The notes pay no interest, provide no dividend exposure, are not listed on any exchange and may have limited liquidity. All payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., and the estimated value on the trade date is disclosed as lower than the issue price due to selling, structuring and hedging costs and the use of an internal funding rate. U.S. tax treatment is uncertain and expected to follow a prepaid forward contract characterization.

The estimated value on the pricing date is expected to be at least $928 per security, below the $1,000 issue price, reflecting structuring and hedging costs.

Citigroup may call the securities in whole on any coupon payment date (other than maturity) for $1,000 plus the coupon. The issue price is $1,000 per security (or $995 for fiduciary accounts), with an estimated value of $990.70 based on internal models.

The notes pay a contingent coupon of at least 0.8542% of principal per month (about 10.25% per annum) only if, on the relevant valuation date, the worst-performing index is at or above 70% of its initial level; otherwise no coupon is paid. Citigroup may call the notes in whole on specified dates, paying $1,000 plus any due coupon, which can shorten the investment horizon.

If the notes are not called, principal repayment at maturity depends solely on the worst-performing index: investors receive full principal back only if that index finishes at or above its 70% final barrier; otherwise, repayment is $1,000 + $1,000 × underlying return of the worst index, with no minimum, so losses can reach 100%. Dividends on the indices are forgone, and investors have exposure to Citigroup Global Markets Holdings Inc. and Citigroup Inc. credit risk, limited liquidity and complex U.S. tax treatment. The issue price is $1,000 per note, including up to $7 in underwriting fees, with estimated value on the pricing date expected to be at least $937.50.

If a downside event occurs, investors receive a fixed number of Monolithic Power Systems shares (or, at Citigroup’s option, cash) that may be worth substantially less than principal and could be zero, in addition to the final coupon. The estimated value on the pricing date is expected to be at least $4,585 per security, below the issue price, reflecting structuring and hedging costs and the issuer’s funding rate.

CITIGROUP INC (C), through Citigroup Global Markets Holdings Inc., is offering unsecured, senior, equity-linked medium-term notes tied to the worst-performing of the EURO STOXX 50® Index, Nasdaq‑100 Index® and Russell 2000® Index, maturing September 8, 2031 and fully and unconditionally guaranteed by Citigroup Inc.

The notes pay a contingent coupon of 2.9375% per quarter (11.75% per annum) only if, on each valuation date, the worst-performing index is at or above 70% of its initial level; otherwise no coupon is paid for that period. Principal repayment is contingent: if held to maturity and the worst-performing index is at or above 60% of its initial level, investors receive $1,000 per note (plus any final coupon). If it is below 60%, repayment is reduced 1-for-1 with the index loss, down to zero.

Citigroup may call the notes in whole on specified dates, paying $1,000 plus any due coupon, capping future income. Per-note economics include an issue price of $1,000, an underwriting fee of up to $3.00 and issuer proceeds of $997.00, with an estimated initial value of at least $939.00, reflecting structuring, hedging costs and internal funding rates. The notes carry the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., offer no index upside or dividends, may have limited or no liquidity, and involve complex U.S. tax and non‑U.S. withholding considerations.

CITIGROUP INC (C), via Citigroup Global Markets Holdings Inc., is issuing Autocallable Contingent Coupon Equity Linked Securities tied to the worst performer of the Dow Jones Industrial Average, Nasdaq‑100 Index® and Russell 2000® Index, maturing August 28, 2031.

The notes pay a 0.7458% contingent coupon per month (about 8.95% per year) only if, on each valuation date, the worst‑performing index is at or above its coupon barrier (75% of its initial level). From August 25, 2027, the notes are subject to automatic early redemption at $1,000 plus coupon if the worst index is at or above its initial level.

At maturity, if not called and the worst index is at or above 70% of its initial level, holders receive $1,000 per note (plus any final coupon). If it is below 70%, repayment is reduced one‑for‑one with the index loss, potentially down to $0.

The note pays a quarterly contingent coupon of 1.1375% of principal (an annualized 13.65%) only if, on the relevant valuation date, the index is at or above the coupon barrier of 5,903.064, which is 60% of the initial index level of 9,838.44. Missed coupons can be recouped later if the barrier is met, but may be lost entirely.

The notes are autocallable on scheduled dates from August 26, 2027 through July 28, 2031 if the index is at or above its initial level; in that case investors receive $1,000 plus the due coupon and any unpaid coupons, ending further payments. If not called, maturity payoff depends on the final index level: if at or above the final barrier (also 60% of initial), investors receive full principal plus the final coupon; if below, repayment equals $1,000 + ($1,000 × index return), exposing holders to 1-for-1 downside below the barrier and potential total loss of principal and coupons.

The underlying index targets 40% volatility with leverage up to 500%, applies notional costs and a 6% per annum decrement, and is expected to underperform the S&P 500 Index; it also has limited live history and relies on complex intraday trend and mean-reversion signals that may perform poorly. The offering size is $2,603,000 with an underwriting fee of $35 per note; the estimated fair value at pricing is $896.30, below the $1,000 issue price, and secondary market liquidity may be limited. All payments are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., and the U.S. tax treatment is uncertain.

If not called, at maturity investors receive: $1,000 plus the final premium if the index is at or above the autocall barrier; $1,000 if it is below the autocall barrier but at or above the final barrier of 413.916 (60%); or $1,000 plus $1,000 times the index return if below the final barrier, exposing principal 1-for-1 to index losses.

The underlying index is complex and risky, using up to 500% leverage on S&P 500 futures, a 40% volatility target, and a 6% per annum decrement, and is expected to underperform the S&P 500® Index. All payments depend on the credit of Citigroup Global Markets Holdings Inc. and Citigroup Inc., there may be little or no secondary market, and the estimated value on the pricing date is $954.70 per $1,000 issue price.

Citigroup may redeem the notes early on specified dates at $1,000 plus any due coupon. The estimated value is $989.10 per note, below the $1,000 issue price, reflecting structuring and hedging costs, and the securities are subject to Citigroup Global Markets Holdings Inc. and Citigroup Inc. credit risk and limited secondary market liquidity.
