[424B2] Morgan Stanley Prospectus Supplement

Rhea-AI Filing Summary

Citigroup Global Markets Holdings Inc. ("CGMHI"), fully guaranteed by Citigroup Inc. (ticker: C), is offering Callable Contingent Coupon Equity-Linked Securities maturing 15 October 2026 and linked to the worst performer of the EURO STOXX 50®, Russell 2000® and S&P 500® indices.

Key economic terms

• Issue price: $1,000 per note; estimated value on the pricing date: $996.50.
• Contingent coupon: 11.05% p.a. (2.7625% quarterly) paid only if, on the relevant valuation date, the worst-performing index is ≥ 70% of its initial level.
• Barriers: Coupon barrier 70%; Final barrier 65% of each index’s initial value.
• Principal repayment: • If worst index ≥ 65% on final valuation date → full $1,000 (plus final coupon, if applicable). • If worst index < 65% → principal reduced 1:1 with index decline, down to zero.
• Callable at issuer’s option quarterly (Oct-25, Jan-26, Apr-26, Jul-26). If called, investor receives $1,000 plus the coupon for that quarter; no further payments.
• Credit: Senior unsecured obligation of CGMHI, guaranteed by Citigroup Inc.; CUSIP 17333LJE6.
• Size: $10 million aggregate offering; underwriting fee waived (sold at par).
• Listing: None; secondary market, if any, solely through CGMI on a best-efforts basis.

Illustrative payouts

• If all quarterly observations remain ≥ 70%, total return ≈ 17.6% (11.05% annualised) plus full principal, or earlier redemption at par.
• In worst-case scenario where final index level falls > 35% below initial, investor could lose up to 100% of principal and receive zero coupons.

Principal risks highlighted by the issuer

• Market risk: Performance depends solely on the worst index on each valuation date; lack of correlation between indices increases probability of missed coupons and principal loss.
• Credit risk: Payments are subject to the creditworthiness of both CGMHI and Citigroup Inc.
• Liquidity risk: No exchange listing; CGMI may discontinue market-making at any time.
• Call risk: Notes likely to be redeemed when conditions favour the issuer, limiting upside for investors.
• Valuation risk: Estimated value below issue price reflects internal funding rate and hedging costs; secondary market bids expected to be below par.
• Tax uncertainty: Treated as prepaid forward with ordinary-income coupons; alternative IRS views possible; withholding of 30% may apply to non-U.S. holders.

This structured note targets investors seeking elevated income in exchange for taking concentrated downside exposure to major equity indices, accepting potential loss of principal, limited liquidity and complex tax treatment.

Positive

• High contingent coupon of 11.05% p.a. offers income well above conventional Citigroup senior debt of similar maturity.
• Full Citigroup Inc. guarantee adds an extra credit backstop relative to standalone subsidiaries.
• Issuer call provision allows investors to be repaid at par plus coupon if markets rally, limiting duration risk.
• No underwriting fee disclosed; notes offered at par, reducing initial cost drag.

Negative

• Principal at risk up to 100% if any index closes below 65% of initial level at final valuation.
• Coupon is contingent; investors may receive zero income if worst index is below 70% on any observation date.
• Estimated value ($996.50) below issue price indicates negative mark-to-market from day one.
• Issuer has unilateral call right, capping upside and creating reinvestment risk.
• No exchange listing and limited secondary market expose holders to significant liquidity risk.
• Complex tax treatment; IRS could challenge prepaid-forward characterization, with 30% withholding possible for non-U.S. investors.

Insights

Structured Products Analyst

TL;DR Routine high-coupon, worst-of index note: attractive yield but high principal risk; minimal impact on Citigroup’s balance sheet.

The 11.05% contingent coupon sits at the upper end of recent worst-of index offerings, reflecting increased equity volatility and only 30-35% protection buffers. Because payments stop if any index closes <70% on a quarterly date, historical drawdowns show a meaningful probability of missing multiple coupons. The 65% final barrier exposes holders to steep tail risk—an 40% S&P retracement would slash redemption to $600. From the issuer’s perspective, the $10 million size is immaterial; the call feature provides balance-sheet flexibility if markets rally, capping funding costs. The absence of underwriting fees suggests a fee-based distribution channel, but investors still pay through the bid/offer spread and a secondary value likely below 99% at issuance. Overall, the note is suitable only for sophisticated yield-seekers who can tolerate equity downside and liquidity constraints.

Portfolio Manager – Multi-Asset

TL;DR High coupon compensates for worst-of risk; useful for tactical income but poor core holding.

With a maximum 15-month tenor and quarterly call, this security may deliver double-digit annualised income if indices stay flat to moderately down. However, historical 12-month drawdowns show that the Russell 2000 breached the 65% barrier in 18% of rolling periods since 2000; adding the European component further skews odds against investors. The asymmetric payoff (no upside participation) means risk-adjusted return is inferior to simply writing index puts with defined collateral. Liquidity and tax opacity further weaken the risk/return proposition. Consequently, I classify the product as a tactical income enhancer, not a strategic allocation. Impact on Citigroup stock is negligible.

Estimated Value of the Securities

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000. Our estimate of the value of the securities as determined on the pricing date will be within the range specified on the cover hereof and will be set forth on the cover of the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlier. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlier, instruments based on the underlier, volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.

What determines the economic terms of the securities?

In determining the economic terms of the securities, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?

The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underlier, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underlier, and to our secondary market credit spreads, it would do so based on values higher than the estimated value. We expect that those higher values will also be reflected in your brokerage account statements.

MS & Co. may, but is not obligated to, make a market in the securities, and, if it once chooses to make a market, may cease doing so at any time.

Hypothetical Examples

Hypothetical Payoff Diagram

The payoff diagram below illustrates the payment at maturity for a range of hypothetical performances of the underlier over the term of the securities, based on the following terms:

Stated principal amount:	$1,000 per security
Upside payment:	$610.00 per security (61.00% of the stated principal amount)
Buffer level:	85% of the initial level
Buffer amount:	15%
Minimum payment at maturity:	15% of the stated principal amount
Hypothetical Payoff Diagram
 

￭Upside Scenario. If the final level is greater than or equal to the buffer level, investors will receive the stated principal amount plus the upside payment per security.

oIf the underlier appreciates 100%, investors will receive a 61.00% return, or $1,610.00 per security.

oIf the underlier appreciates 10%, investors will receive a 61.00% return, or $1,610.00 per security.

oIf the underlier depreciates 5%, investors will receive a 61.00% return, or $1,610.00 per security.

￭Downside Scenario. If the final level is less than the buffer level, investors will receive an amount that is less, and may be significantly less, than the stated principal amount, based on a 1% loss of principal for each 1% decline in the level of the underlier beyond the buffer amount.

oIf the underlier depreciates 85%, investors will lose 70% of their principal and receive only $300 per security at maturity, or 30% of the stated principal amount.

Risk Factors

This section describes the material risks relating to the securities. For further discussion of these and other risks, you should read the section entitled “Risk Factors” in the accompanying product supplement and prospectus. We also urge you to consult with your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

Risks Relating to an Investment in the Securities

￭The securities provide for only the minimum payment at maturity and do not pay interest. The terms of the securities differ from those of ordinary debt securities in that they provide for only the minimum payment at maturity and do not pay interest. If the final level is less than the buffer level, the payout at maturity will be an amount in cash that is less than the stated principal amount of each security, and you will lose an amount proportionate to the full decline in the level of the underlier over the term of the securities beyond the buffer amount. You could lose a significant portion of your initial investment in the securities.

￭The appreciation potential of the securities is fixed and limited. Where the final level is greater than or equal to the buffer level, the appreciation potential of the securities is limited by the fixed upside payment, even if the final level is significantly greater than the initial level.

￭The amount payable on the securities is not linked to the value of the underlier at any time other than the observation date. The final level will be based on the closing level of the underlier on the observation date, subject to postponement for non-trading days and certain market disruption events. Even if the value of the underlier appreciates prior to the observation date but then drops by the observation date, the payment at maturity may be less, and may be significantly less, than it would have been had the payment at maturity been linked to the value of the underlier prior to such drop. Although the actual value of the underlier on the stated maturity date or at other times during the term of the securities may be higher than the closing level of the underlier on the observation date, the payment at maturity will be based solely on the closing level of the underlier on the observation date.

￭The market price of the securities may be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market. We expect that generally the value of the underlier at any time will affect the value of the securities more than any other single factor. Other factors that may influence the value of the securities include:

othe volatility (frequency and magnitude of changes in value) of the underlier;

ointerest and yield rates in the market;

ogeopolitical conditions and economic, financial, political, regulatory or judicial events that affect the underlier or equity markets generally;

othe availability of comparable instruments;

othe composition of the underlier and changes in the component securities of the underlier;

othe time remaining until the securities mature; and

oany actual or anticipated changes in our credit ratings or credit spreads.

Some or all of these factors will influence the price that you will receive if you sell your securities prior to maturity. Generally, the longer the time remaining to maturity, the more the market price of the securities will be affected by the other factors described above. For example, you may have to sell your securities at a substantial discount from the stated principal amount if, at the time of sale, the closing level of the underlier is at, below or not sufficiently above the buffer level, or if market interest rates rise.

You can review the historical closing levels of the underlier in the section of this document called “Historical Information.” You cannot predict the future performance of the underlier based on its historical performance. The value of the underlier may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. There can be no assurance that the final level will be greater than or equal to the buffer level so that you do not suffer a loss on your initial investment in the securities.

￭The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. You are dependent on our ability to pay all amounts due on the securities, and, therefore, you are subject to our credit risk. The securities are not guaranteed by any other entity. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

￭As a finance subsidiary, MSFL has no independent operations and will have no independent assets. As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a

&nbsp;

bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank pari passu with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated pari passu with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanley-issued securities.

￭The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to purchase the securities in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bid-offer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.

The inclusion of the costs of issuing, selling, structuring and hedging the securities in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the securities less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, to the extent that MS & Co. may buy or sell the securities in the secondary market during the amortization period specified herein, absent changes in market conditions, including those related to the underlier, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.

￭The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price of the securities may be influenced by many unpredictable factors” above.

￭The securities will not be listed on any securities exchange and secondary trading may be limited. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. MS & Co. may, but is not obligated to, make a market in the securities and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

￭As discussed in more detail in the accompanying product supplement, investing in the securities is not equivalent to investing in the underlier(s).

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority regarding the proper U.S. federal income tax treatment of the securities, and significant aspects of the tax treatment of the securities are uncertain. You should review carefully the section entitled “United States Federal Income Tax Considerations” herein, in combination with the section entitled “United States Federal Income Tax Considerations” in the accompanying product supplement, and consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities.

Risks Relating to the Underlier(s)

￭Because your return on the securities will depend upon the performance of the underlier(s), the securities are subject to the following risk(s), as discussed in more detail in the accompanying product supplement.

oAdjustments to an underlying index could adversely affect the value of the securities.

Risks Relating to Conflicts of Interest

In engaging in certain activities described below and as discussed in more detail in the accompanying product supplement, our affiliates may take actions that may adversely affect the value of and your return on the securities, and in so doing they will have no obligation to consider your interests as an investor in the securities.

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will make any determinations necessary to calculate any payment(s) on the securities. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, which may adversely affect your return on the securities. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the securities.

Additional Information About the Securities

Additional Information:
Minimum ticketing size:	$1,000 / 1 security
United States federal income tax considerations:	You should review carefully the section in the accompanying product supplement entitled “United States Federal Income Tax Considerations.” The following discussion, when read in combination with that section, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the securities. Generally, this discussion assumes that you purchased the securities for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to an underlier. You should consult your tax adviser regarding the effect any such circumstances may have on the U.S. federal income tax consequences of your ownership of a security. In the opinion of our counsel, which is based on current market conditions, it is reasonable to treat the securities for U.S. federal income tax purposes as prepaid financial contracts that are “open transactions,” as described in the section entitled “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Securities Treated as Prepaid Financial Contracts that are Open Transactions” in the accompanying product supplement. There is uncertainty regarding this treatment, and the IRS or a court might not agree with it. Moreover, because this treatment of the securities and our counsel’s opinion are based on market conditions as of the date of this preliminary pricing supplement, each is subject to confirmation on the pricing date. A different tax treatment could be adverse to you. Generally, if this treatment is respected, (i) you should not recognize taxable income or loss prior to the taxable disposition of your securities (including upon maturity or an earlier redemption, if applicable) and (ii) the gain or loss on your securities should be treated as capital gain or loss. We do not plan to request a ruling from the IRS regarding the treatment of the securities. An alternative characterization of the securities could materially and adversely affect the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. Non-U.S. Holders. As discussed under “United States Federal Income Tax Considerations—Tax Consequences to Non-U.S. Holders—Dividend Equivalents under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. The Treasury regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2027 that do not have a “delta” of one. Based on certain determinations made by us, we expect that Section 871(m) will not apply to the securities with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. If necessary, further information regarding the potential application of Section 871(m) will be provided in the final pricing supplement for the securities. We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

FAQ

What is the coupon rate on Citigroup's 2025 424B2 equity-linked securities?

The notes pay a contingent coupon of 2.7625% quarterly, equivalent to 11.05% per annum, only when the worst-performing index is ≥ 70% of its initial level.

How much principal protection do the Citigroup (C) notes provide at maturity?

Principal is protected only if the worst index is above 65% of its initial value; below that, repayment is reduced 1-for-1 and can be zero.

Can Citigroup redeem the securities early?

Yes. The issuer may call the notes on quarterly coupon dates starting Oct 2025. Investors then receive $1,000 plus the due coupon, ending further payments.

Will the securities be listed on an exchange?

No. No listing is planned; any secondary liquidity relies on CGMI’s best-efforts market-making.

Why is the estimated value ($996.50) lower than the $1,000 issue price?

The difference reflects internal funding costs, hedging expenses and expected dealer profit; it also means secondary bids may open below par.

What indices determine payouts on these Citigroup notes?

Payouts depend on the EURO STOXX 50®, Russell 2000® and S&P 500®; the note references the worst-performing of the three.
