Citigroup Issues $13 Million in Autocallable Buffer Securities Linked to S&P 500 Index

Structure and Mechanics of the Autocallable Offering

The securities issued by Citigroup Global Markets Holdings are unsecured debt securities guaranteed by parent company Citigroup Inc. Unlike conventional debt instruments, these notes do not pay periodic interest and offer no guarantee of principal repayment at maturity. Instead, returns depend entirely on the performance of the S&P 500 Index measured on specified valuation dates. The stated principal amount is $1,000 per security, with an issue date of July 23, 2026, and maturity date of July 25, 2028, unless earlier redeemed through the automatic redemption feature.

The filing discloses two key valuation dates: July 27, 2027, and July 20, 2028 (the final valuation date). If the closing value of the S&P 500 on the first valuation date equals or exceeds the initial underlying value of 7,457.69, the securities will be automatically redeemed on the third business day following that date. Upon automatic redemption, investors receive $1,105 per security—the full $1,000 stated principal plus a 10.50% premium totaling $105. This early redemption feature terminates the security and removes any opportunity for further index participation.

Downside Buffer and Loss Mechanics

A defining feature of these securities is the 20% downside buffer, which protects investors from loss if the S&P 500 declines moderately but exposes them to full losses if the decline exceeds the buffer. The final buffer value is set at 5,966.152, representing exactly 80% of the initial underlying value. If the securities are not redeemed early and the index closes at or above the initial underlying value on the final valuation date, investors receive their full $1,000 principal plus participation in the index appreciation at a 100% upside participation rate.

However, if the index declines below the initial value but remains above the buffer level, investors receive only their stated principal amount of $1,000 with no additional return. The filing explains that if the final underlying value falls below the final buffer value—meaning the index has depreciated more than 20% from the strike level—investors incur a loss of 1% of stated principal for every 1% by which the depreciation exceeds the 20% buffer. This structure means investors bear full downside exposure beyond the buffer threshold but sacrifice dividend income from the underlying index.

Pricing and Valuation Considerations

The securities were priced at $1,000 per security on July 20, 2026, with a total aggregate amount of $13 million. Citigroup Global Markets Inc., acting as principal underwriter, charged a $1 per-security underwriting fee, resulting in net proceeds to the issuer of $999 per security or $12,987,000 in aggregate. The filing discloses that on the pricing date, the estimated value of the securities was $995.20 per security, below the issue price, based on Citigroup's proprietary pricing models and internal funding rate.

The filing emphasizes that the estimated valuation is not an indication of actual profit to Citigroup or its affiliates, nor is it a binding offer price for secondary market purchases. Investors should note that Citigroup and its affiliates may generate additional profits through hedging activities related to the offering, independent of whether the securities' value increases or declines. The estimated value of $995.20 suggests the securities carried a modest valuation discount relative to issuance price, a common feature in structured product offerings where embedded optionality is priced into the terms.

Strike Date and Key Dates in the Security Timeline

The strike date—the date on which the initial underlying value is fixed—was July 17, 2026, when the S&P 500 closed at 7,457.69. This level serves as the reference point for all subsequent performance calculations. The pricing date followed three days later on July 20, 2026, and the issue date was scheduled for July 23, 2026. These three dates establish the temporal framework within which the securities are structured and valued.

The first valuation date is July 27, 2027, one year from the pricing date. If this date falls on a non-trading day or is subject to certain market disruption events, the valuation will be postponed to the next scheduled trading day. The final valuation date is July 20, 2028, exactly two years from the pricing date. Both valuation dates are subject to similar postponement provisions. The maturity date, absent early automatic redemption, is July 25, 2028, five business days after the final valuation date, allowing for settlement and payment processing.

Credit Risk and Guarantee Structure

All payments due on the securities are fully and unconditionally guaranteed by Citigroup Inc., the parent company of Citigroup Global Markets Holdings Inc. The filing makes clear that investors assume the credit risk of both the issuer and the guarantor. This dual-entity structure is common in structured product offerings by large financial institutions, where a subsidiary issues the securities and the parent provides credit backing. If either Citigroup Global Markets Holdings or Citigroup Inc. defaults on their obligations, investors may not receive payment regardless of the underlying index's performance.

The filing explicitly warns that the securities are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. This disclosure highlights that investors bear credit risk without the safety net of deposit insurance. The filing further cautions that these are unsecured obligations, meaning investors do not have a secured claim on specific assets of Citigroup in the event of default or bankruptcy.

Hypothetical Payment Scenarios at Automatic Redemption

The filing provides a concrete example of payment upon automatic early redemption. If the S&P 500 closes at or above 7,457.69 on July 27, 2027, investors will receive $1,105 per security. This amount represents the full $1,000 stated principal plus the applicable 10.50% premium of $105. The security will then cease to be outstanding, and investors lose the ability to participate in any further appreciation of the index or potential additional gains.

This early redemption feature creates an asymmetry in investor returns: the issuer benefits if the index rallies significantly, as it can redeem the securities at the fixed 10.50% premium while capturing the excess upside through its hedging position. Conversely, if the index remains flat or declines to the point where automatic redemption does not occur, investors retain downside exposure subject to the 20% buffer. The filing does not disclose the likelihood or probability of automatic redemption but notes that the premium "may be significantly less than the appreciation of the underlying from the pricing date to the valuation date prior to the final valuation date."

Liquidity Risk and Market Conditions

The filing emphasizes that investors must be willing to accept an investment that may have limited or no liquidity. The securities will not be listed on any securities exchange, meaning investors cannot readily trade them on a public market. Secondary market trading, if available at all, would likely occur through over-the-counter channels, typically with limited dealer participation and potentially wide bid-ask spreads. The filing cautions that there is no obligation for any dealer, including Citigroup, to make a market in the securities after issuance.

This liquidity constraint is a material risk factor that distinguishes structured products from conventional securities. An investor who wishes to exit a position before maturity or automatic redemption may face difficulty finding a buyer or may be forced to accept a significantly discounted price. The filing does not provide any indication of whether secondary market liquidity will be available or at what terms, leaving investors with limited clarity on exit opportunities.

Tax Treatment and Regulatory Disclosures

The filing notes that it is filed pursuant to Rule 424(b)(2) under the Securities Act of 1933, as a pricing supplement to existing registration statements numbered 333-293732 and 333-293732-02. This indicates the securities are offered through an effective shelf registration statement that allows Citigroup to issue various structured products on a continuous basis. The filing references accompanying product supplement EA-02-12, underlying supplement 13, and prospectus documents, all dated February 25, 2026, which contain additional terms, conditions, and disclosures not repeated in the pricing supplement itself.

The filing includes standard SEC disclaimers stating that neither the Securities and Exchange Commission nor any state securities regulator has approved or disapproved the securities, nor has any regulator determined that the offering documentation is truthful or complete. The filing reminds investors that they must read all accompanying documents in connection with their investment decision. Tax treatment of the securities is not addressed in the pricing supplement itself, suggesting investors should consult the accompanying prospectus documents and a tax advisor regarding the appropriate tax classification and reporting of gains or losses.

Distribution and Underwriting Arrangement

Citigroup Global Markets Inc. serves as the principal underwriter of the offering, purchasing the entire $13 million aggregate principal amount at a discount equal to the $1 per-security underwriting fee. This arrangement, in which an affiliate of the issuer acts as principal underwriter, is standard for Citigroup's structured product offerings. The underwriter's spread of 0.10% (calculated as $1,000 / $1,000,000 × 100) is modest relative to traditional bond underwriting spreads but aligns with typical structured product distribution economics.

The filing discloses that in addition to the underwriting fee, Citigroup and its affiliates may profit from hedging activity related to the offering, even if the value of the securities declines after issuance. This statement reflects the reality that structured product issuers typically hedge their exposure to the underlying index by purchasing call options, interest rate swaps, or other derivatives. If the index declines significantly after issuance, the cost of hedging may decrease, allowing the issuer to realize gains on its hedging positions even as the securities lose value. This dynamic creates a potential conflict of interest, as the issuer benefits from declines in the securities' value under certain market conditions.

Key Risks and Investor Considerations

The filing identifies several material risks that distinguish these securities from conventional debt. First, investors have no downside protection until the S&P 500 declines more than 20% from the strike level. Beyond that threshold, losses are dollar-for-dollar. Second, investors do not receive dividends paid on the S&P 500 Index, meaning they sacrifice income that conventional S&P 500 index investments would provide. Third, the upside participation is capped by the automatic redemption feature at 10.50% on July 27, 2027, eliminating the possibility of greater gains if the index continues to rise.

Fourth, the securities carry credit risk of Citigroup, meaning default by the issuer or guarantor eliminates all payment prospects. Fifth, secondary market liquidity is uncertain, potentially trapping investors in illiquid positions. Sixth, market disruption events could postpone valuation dates, extending the holding period and delaying payments. Finally, the securities are complex instruments requiring careful understanding of embedded options and conditional payments. The filing emphasizes that these are unsecured obligations carrying significantly higher risk profiles than conventional senior debt issued by the same entities.
