Autocallable Securities Linked to the Worst Performing of the Dow Jones Industrial Average™, the Russell 2000<sup>®</sup> Index and the S&P 500<sup>®</sup> Index Due July 30, 2031

▪ The securities offered by this pricing supplement are unsecured
debt securities issued by Citigroup Global Markets Holdings Inc. and guaranteed by Citigroup Inc. Unlike conventional debt
securities, the securities do not pay interest, do not guarantee the repayment of principal at maturity and are subject to potential
automatic early redemption on a periodic basis on the terms described below. Your return on the securities will depend solely on the
performance of the **worst performing** of the underlyings specified below.

▪ The securities offer the potential for automatic early redemption
at a premium following the first valuation date (other than the final valuation date) on which the closing value of the worst performing
underlying on that valuation date is greater than or equal to its then-applicable premium threshold value. If the securities are not
automatically redeemed prior to maturity, the securities will provide for (i) repayment of the stated principal amount plus a premium
at maturity if the final underlying value of the worst performing underlying on the final valuation date is greater than or equal to
its final premium threshold value or (ii) repayment of the stated principal amount at maturity, with no premium, if the final underlying
value of the worst performing underlying on the final valuation date is less than its final premium threshold value but greater than
or equal to its trigger value. **However, if the securities are not automatically redeemed prior to maturity and the final underlying value of the worst performing underlying on the final valuation date is less than its trigger value, you will incur a significant loss at maturity and will have full downside exposure to the depreciation of the worst performing underlying from its initial underlying value to its final underlying value.** 

▪ You will be subject to risks associated with <u>each</u> of
the underlyings and will be negatively affected by adverse movements in <u>any one</u> of the underlyings. Although you will have downside
exposure to the worst performing underlying on the final valuation date, you will not receive dividends with respect to any underlying
or participate in any appreciation of any underlying.

▪ Investors in the securities must be willing to accept (i) an
investment that may have limited or no liquidity and (ii) the risk of not receiving any payments due under the securities if we and Citigroup
Inc. default on our obligations. **All payments on the securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.**

Hypothetical Payment Upon Automatic Early Redemption

The following table illustrates how the amount payable per security upon automatic early redemption will be calculated if the closing value of the worst performing underlying on any valuation date prior to the final valuation date is greater than or equal to its then-applicable premium threshold value. The tables and diagram below assume that the premium will be set at the minimum level indicated under "Key Terms" above. The actual premium applicable to each valuation date will be determined on the pricing date.

---

| | | |
|:---|:---|:---|
| **If the closing value of the worst performing underlying on the following valuation date. . .** | **…is greater than or equal to the following premium threshold level…** | **. . . then you will receive the following payment per $1,000 security upon automatic early redemption:** |
| 1<sup>st</sup> valuation date | 95.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $94.50 = $1,094.50 |
| 2<sup>nd</sup> valuation date | 95.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $141.75 = $1,141.75 |
| 3<sup>rd</sup> valuation date | 95.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $189.00 = $1,189.00 |
| 4<sup>th</sup> valuation date | 95.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $236.25 = $1,236.25 |
| 5<sup>th</sup> valuation date | 95.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $283.50 = $1,283.50 |
| 6<sup>th</sup> valuation date | 85.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $330.75 = $1,330.75 |
| 7<sup>th</sup> valuation date | 85.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $378.00 = $1,378.00 |
| 8<sup>th</sup> valuation date | 85.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $425.25 = $1,425.25 |
| 9<sup>th</sup> valuation date | 85.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $472.50 = $1,472.50 |
| 10<sup>th</sup> valuation date | 85.00% of the Initial Level | $1,000.00 + applicable premium = $1,000.00 + $519.75 = $1,519.75 |

---

**If, on any valuation date prior to the final valuation date, the closing value of any underlying is less than its then-applicable premium threshold value, you will not receive the premium indicated above following that valuation date. In order to receive the premium indicated above, the closing value of *each* underlying on the applicable valuation date must be greater than or equal to its then-applicable premium threshold value.**

Payment at Maturity Diagram

The diagram below illustrates the payment at maturity of the securities, assuming the securities have not previously been automatically redeemed, for a range of hypothetical underlying returns of the worst performing underlying on the final valuation date. Your payment at maturity (if the securities are not earlier automatically redeemed) will be determined based solely on the performance of the worst performing underlying on the final valuation date.

**Investors in the securities will not receive any dividends with respect to the underlyings. The diagram and examples below do not show any effect of lost dividend yield over the term of the securities.** See "Summary Risk Factors—You will not receive dividends or have any other rights with respect to the underlyings" below.

Hypothetical Examples of the Payment at Maturity

The examples below are intended to illustrate how, if the securities are not automatically redeemed prior to maturity, your payment at maturity will depend on the final underlying value of the worst performing underlying on the final valuation date. Your actual payment at maturity per security, if the securities are not automatically redeemed prior to maturity, will depend on the actual final underlying value of the worst performing underlying on the final valuation date. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of any payment that may be made on the securities.

The examples below are based on the following hypothetical values and do not reflect the actual initial underlying values, trigger values or final premium threshold values of the underlyings. For the actual initial underlying value, trigger value and final premium threshold value of each underlying, see the cover page of this pricing supplement. We have used these hypothetical values, rather than the actual values, to simplify the calculations and aid understanding of how the securities work. However, you should understand that the actual payments on the securities will be calculated based on the actual initial underlying value, trigger value and final premium threshold value of each underlying, and not the hypothetical values indicated below. For ease of analysis, figures below may have been rounded.

---

| | | | |
|:---|:---|:---|:---|
| **Underlying** | **Hypothetical initial underlying value** | **Hypothetical trigger value** | **Hypothetical final premium threshold value** |
| Dow Jones Industrial Average™ | 100 | 75 (75% of its hypothetical initial underlying value) | 85 (85% of its hypothetical initial underlying value) |
| Russell 2000<sup>®</sup> Index | 100 | 75 (75% of its hypothetical initial underlying value) | 85 (85% of its hypothetical initial underlying value) |
| S&P 500<sup>®</sup> Index | 100 | 75 (75% of its hypothetical initial underlying value) | 85 (85% of its hypothetical initial underlying value) |

**Example 1—Upside Scenario A.**

---

| | | |
|:---|:---|:---|
| **Underlying** | **Hypothetical final underlying value** | **Hypothetical underlying return** |
| Dow Jones Industrial Average™ | 130.00 | 30.00% |
| Russell 2000<sup>®</sup> Index | 95.00 | -5.00% |
| S&P 500<sup>®</sup> Index | 110.00 | 10.00% |

---

In this example, the Russell 2000<sup>®</sup> Index has the lowest underlying return and is, therefore, the worst performing underlying on the final valuation date. Because the final underlying value of the worst performing underlying on the final valuation date is greater than its final premium threshold value, you would be repaid the stated principal amount of your securities at maturity *plus* the premium applicable to the final valuation date.

Payment at maturity per security = $1,000 + the premium applicable to the final valuation date

= $1,000 + $567.00

= $1,567.00

**Example 2—Upside Scenario B.**

---

| | | |
|:---|:---|:---|
| **Underlying** | **Hypothetical final underlying value** | **Hypothetical underlying return** |
| Dow Jones Industrial Average™ | 160.00 | 60.00% |
| Russell 2000<sup>®</sup> Index | 165.00 | 65.00% |
| S&P 500<sup>®</sup> Index | 170.00 | 70.00% |

---

In this example, the Dow Jones Industrial Average™ has the lowest underlying return and is, therefore, the worst performing underlying on the final valuation date. Because the final underlying value of the worst performing underlying on the final valuation date is greater than its final premium threshold value, you would be repaid the stated principal amount of your securities at maturity *plus* the premium applicable to the final valuation date.

Payment at maturity per security = $1,000 + the premium applicable to the final valuation date

<u>Citigroup Global Markets Holdings Inc.</u> <br>

= $1,000 + $567.00

= $1,567.00

In this example, an investment in the securities would underperform a hypothetical alternative investment providing 1-to-1 exposure to the appreciation of the worst performing underlying.

**Example 3—Par Scenario.**

| Russell 2000<sup>®</sup> Index | 90.00 | -10.00% |
| S&P 500<sup>®</sup> Index | 80.00 | -20.00% |

---

In this example, the S&P 500<sup>®</sup> Index has the lowest underlying return and is, therefore, the worst performing underlying on the final valuation date. Because the final underlying value of the worst performing underlying on the final valuation date is less than its final premium threshold value but greater than its trigger value, you would be repaid the stated principal amount of $1,000 per security at maturity but would not receive any premium.

**Example 4—Downside Scenario.**

| | | |
|:---|:---|:---|
| **Underlying** | **Hypothetical final underlying value** | **Hypothetical underlying return** |
| Dow Jones Industrial Average™ | 30.00 | -70.00% |
| Russell 2000<sup>®</sup> Index | 105.00 | 5.00% |
| S&P 500<sup>®</sup> Index | 80.00 | -20.00% |

---

In this example, the Dow Jones Industrial Average™ has the lowest underlying return and is, therefore, the worst performing underlying on the final valuation date. Because the final underlying value of the worst performing underlying on the final valuation date is less than its trigger value, you would receive a payment at maturity per security that is significantly less than the stated principal amount, calculated as follows:

Payment at maturity per security = $1,000 + ($1,000 × the underlying return of the worst performing underlying on the final valuation date)

= $1,000 + ($1,000 × -70%)

= $1,000 + -$700.00

= $300.00

In this example, you would incur a significant loss at maturity and would have full downside exposure to the depreciation of the worst performing underlying on the final valuation date from its initial underlying value to its final underlying value.

Summary Risk Factors

An investment in the securities is significantly riskier than an investment in conventional debt securities. The securities are subject to all of the risks associated with an investment in our conventional debt securities (guaranteed by Citigroup Inc.), including the risk that we and Citigroup Inc. may default on our obligations under the securities, and are also subject to risks associated with each underlying. Accordingly, the securities are suitable only for investors who are capable of understanding the complexities and risks of the securities. You should consult your own financial, tax and legal advisors as to the risks of an investment in the securities and the suitability of the securities in light of your particular circumstances.

The following is a summary of certain key risk factors for investors in the securities. You should read this summary together with the more detailed description of risks relating to an investment in the securities contained in the section "Risk Factors Relating to the Securities" beginning on page EA-7 in the accompanying product supplement. You should also carefully read the risk factors included in the accompanying prospectus supplement and in the documents incorporated by reference in the accompanying prospectus, including Citigroup Inc.'s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which describe risks relating to the business of Citigroup Inc. more generally.

Citigroup Inc. will release quarterly earnings on July 15, 2025, which is during the marketing period and prior to the pricing date of these securities.

▪ **You may lose a significant portion or all of your investment.** Unlike conventional debt securities, the securities do not provide
for the repayment of the stated principal amount at maturity in all circumstances. If the securities are not automatically
redeemed prior to maturity, your payment at maturity will depend on the final underlying value of the worst performing underlying on the
final valuation date. If the final underlying value of the worst performing underlying on the final valuation date is less
than its trigger value, you will lose 1% of the stated principal amount of the securities for every 1% by which the worst performing underlying
has declined from its initial underlying value. There is no minimum payment at maturity on the securities, and you may lose
up to all of your investment.

▪ **Your potential return on the securities is limited.** Your potential return on the securities is limited to the applicable
premium payable upon automatic early redemption or at maturity, as described on the cover page of this pricing supplement. If the closing
value of the worst performing underlying on one of the valuation dates is greater than or equal to its then-applicable premium threshold
value or final premium threshold value, you will be repaid the stated principal amount of your securities and will receive the fixed premium
applicable to that valuation date, regardless of how significantly the closing value of the worst performing underlying on that valuation
date may exceed its initial underlying value. Accordingly, any premium may result in a return on the securities that is significantly
less than the return you could have achieved on a direct investment in any or all of the underlyings.

▪ **The securities do not pay interest.** You should not invest in the securities if you seek current income during the term of the
securities.

▪ **The securities are subject to heightened risk because they have multiple underlyings.** The securities are more risky
than similar investments that may be available with only one underlying. With multiple underlyings, there is a greater chance that any
one underlying will perform poorly, adversely affecting your return on the securities.

▪ **The securities are subject to the risks of each of the underlyings and will be negatively affected if any one underlying performs poorly.** You are subject to risks associated with each of the underlyings. If any one underlying performs poorly, you will
be negatively affected. The securities are not linked to a basket composed of the underlyings, where the blended performance of the underlyings
would be better than the performance of the worst performing underlying alone. Instead, you are subject to the full risks of
whichever of the underlyings is the worst performing underlying.

▪ **You will not benefit in any way from the performance of any better performing underlying.** The return on the securities
depends solely on the performance of the worst performing underlying, and you will not benefit in any way from the performance of any
better performing underlying.

▪ **You will be subject to risks relating to the relationship between the underlyings.** It is preferable from your perspective
for the underlyings to be correlated with each other, in the sense that their closing values tend to increase or decrease at similar times
and by similar magnitudes. By investing in the securities, you assume the risk that the underlyings will not exhibit this relationship. The
less correlated the underlyings, the more likely it is that any one of the underlyings will perform poorly over the term of the securities.
All that is necessary for the securities to perform poorly is for one of the underlyings to perform poorly. It is impossible
to predict what the relationship between the underlyings will be over the term of the securities. The underlyings differ in
significant ways and, therefore, may not be correlated with each other.

▪ **The securities may be automatically redeemed prior to maturity, limiting the term of the securities.** If the closing
value of the worst performing underlying on any valuation date (other than the final valuation date) is greater than or equal to its then-applicable
premium threshold value, the securities will be automatically redeemed. If the securities are automatically redeemed following
any valuation date prior to the final valuation date, they will cease to be outstanding and you will not receive the premium applicable
to any later valuation date. Moreover, you may not be able to reinvest your funds in another investment that provides a similar yield
with a similar level of risk.

<u>Citigroup Global Markets Holdings Inc.</u> <br>

▪ **The securities offer downside exposure to the worst performing underlying, but no upside exposure to any underlying.** You will
not participate in any appreciation in the value of any underlying over the term of the securities. Consequently, your return on the securities
will be limited to the applicable premium payable upon an automatic early redemption or at maturity and may be significantly less than
the return on any underlying over the term of the securities.

▪ **You will not receive dividends or have any other rights with respect to the underlyings.** You will not receive any
dividends with respect to the underlyings. This lost dividend yield may be significant over the term of the securities. The
payment scenarios described in this pricing supplement do not show any effect of such lost dividend yield over the term of the securities. In
addition, you will not have voting rights or any other rights with respect to the underlyings or the stocks included in the underlyings.

▪ **The performance of the securities will depend on the closing values of the underlyings solely on the valuation dates, which makes the securities particularly sensitive to volatility in the closing values of the underlyings on or near the valuation dates.** Whether
the securities will be automatically redeemed prior to maturity will depend on the closing values of the underlyings solely on the valuation
dates (other than the final valuation date), regardless of the closing values of the underlyings on other days during the term of the
securities. If the securities are not automatically redeemed prior to maturity, what you receive at maturity will depend solely on the
closing value of the worst performing underlying on the final valuation date, and not on any other day during the term of the securities.
Because the performance of the securities depends on the closing values of the underlyings on a limited number of dates, the securities
will be particularly sensitive to volatility in the closing values of the underlyings on or near the valuation dates. You should understand
that the closing value of each underlying has historically been highly volatile.

▪ **The securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.** If we
default on our obligations under the securities and Citigroup Inc. defaults on its guarantee obligations, you may not receive anything
owed to you under the securities.

▪ **The securities will not be listed on any securities exchange and you may not be able to sell them prior to maturity.** The
securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. CGMI
currently intends to make a secondary market in relation to the securities and to provide an indicative bid price for the securities on
a daily basis. Any indicative bid price for the securities provided by CGMI will be determined in CGMI's sole discretion,
taking into account prevailing market conditions and other relevant factors, and will not be a representation by CGMI that the securities
can be sold at that price, or at all. CGMI may suspend or terminate making a market and providing indicative bid prices without
notice, at any time and for any reason. If CGMI suspends or terminates making a market, there may be no secondary market at
all for the securities because it is likely that CGMI will be the only broker-dealer that is willing to buy your securities prior to maturity. Accordingly,
an investor must be prepared to hold the securities until maturity.

▪ **The estimated value of the securities on the pricing date, based on CGMI's proprietary pricing models and our internal funding rate, is less than the issue price**. The difference is attributable to certain costs associated with selling, structuring
and hedging the securities that are included in the issue price. These costs include (i) any selling concessions or other fees
paid in connection with the offering of the securities, (ii) hedging and other costs incurred by us and our affiliates in connection with
the offering of the securities and (iii) the expected profit (which may be more or less than actual profit) to CGMI or other of our affiliates
in connection with hedging our obligations under the securities. These costs adversely affect the economic terms of the securities
because, if they were lower, the economic terms of the securities would be more favorable to you. The economic terms of the
securities are also likely to be adversely affected by the use of our internal funding rate, rather than our secondary market rate, to
price the securities. See "The estimated value of the securities would be lower if it were calculated based on our secondary
market rate" below.

▪ **The estimated value of the securities was determined for us by our affiliate using proprietary pricing models.** CGMI
derived the estimated value disclosed on the cover page of this pricing supplement from its proprietary pricing models. In
doing so, it may have made discretionary judgments about the inputs to its models, such as the volatility of, and correlation between,
the closing values of the underlyings, dividend yields on the underlyings and interest rates. CGMI's views on these inputs may differ
from your or others' views, and as an underwriter in this offering, CGMI's interests may conflict with yours. Both
the models and the inputs to the models may prove to be wrong and therefore not an accurate reflection of the value of the securities. Moreover,
the estimated value of the securities set forth on the cover page of this pricing supplement may differ from the value that we or our
affiliates may determine for the securities for other purposes, including for accounting purposes. You should not invest in
the securities because of the estimated value of the securities. Instead, you should be willing to hold the securities to maturity
irrespective of the initial estimated value.

▪ **The estimated value of the securities would be lower if it were calculated based on our secondary market rate.** The estimated value of the securities included in this pricing supplement is calculated based on our internal funding
rate, which is the rate at which we are willing to borrow funds through the issuance of the securities. Our internal funding rate is generally
lower than our secondary market rate, which is the rate that CGMI will use in determining the value of the securities for purposes of
any purchases of the securities from you in the secondary market. If the estimated value included in this pricing supplement
were based on our secondary market rate, rather than our internal funding rate, it would likely be lower. We determine our
internal funding rate based on factors such as the costs associated with the securities, which are generally higher than the costs associated
with conventional debt securities, and our liquidity needs and preferences. Our internal funding rate is not an interest rate
that is payable on the securities.

Because there is not an active market for traded instruments referencing our outstanding debt obligations, CGMI determines our secondary market rate based on the market price of traded instruments referencing the debt obligations of Citigroup Inc., our

<u>Citigroup Global Markets Holdings Inc.</u> <br>

parent company and the guarantor of all payments due on the securities, but subject to adjustments that CGMI makes in its sole discretion. As a result, our secondary market rate is not a market-determined measure of our creditworthiness, but rather reflects the market's perception of our parent company's creditworthiness as adjusted for discretionary factors such as CGMI's preferences with respect to purchasing the securities prior to maturity.

▪ **The estimated value of the securities is not an indication of the price, if any, at which CGMI or any other person may be willing to buy the securities from you in the secondary market.** Any such secondary market price will fluctuate over the term of
the securities based on the market and other factors described in the next risk factor. Moreover, unlike the estimated value
included in this pricing supplement, any value of the securities determined for purposes of a secondary market transaction will be based
on our secondary market rate, which will likely result in a lower value for the securities than if our internal funding rate were used. In
addition, any secondary market price for the securities will be reduced by a bid-ask spread, which may vary depending on the aggregate
stated principal amount of the securities to be purchased in the secondary market transaction, and the expected cost of unwinding related
hedging transactions. As a result, it is likely that any secondary market price for the securities will be less than the issue
price.

▪ **The value of the securities prior to maturity will fluctuate based on many unpredictable factors.** The value of your securities
prior to maturity will fluctuate based on the closing values of the underlyings, the volatility of, and correlation between, the closing
values of the underlyings, dividend yields on the underlyings, interest rates generally, the time remaining to maturity and our and Citigroup
Inc.'s creditworthiness, as reflected in our secondary market rate, among other factors described under "Risk Factors Relating
to the Securities—Risk Factors Relating to All Securities—The value of your securities prior to maturity will fluctuate based
on many unpredictable factors" in the accompanying product supplement. Changes in the closing values of the underlyings
may not result in a comparable change in the value of your securities. You should understand that the value of your securities
at any time prior to maturity may be significantly less than the issue price.

▪ **Immediately following issuance, any secondary market bid price provided by CGMI, and the value that will be indicated on any brokerage account statements prepared by CGMI or its affiliates, will reflect a temporary upward adjustment.** The amount of this temporary
upward adjustment will steadily decline to zero over the temporary adjustment period. See "Valuation of the Securities"
in this pricing supplement.

▪ **The Russell 2000<sup>®</sup> Index is subject to risks associated with small capitalization stocks.** The stocks
that constitute the Russell 2000<sup>®</sup> Index are issued by companies with relatively small market capitalization. The
stock prices of smaller companies may be more volatile than stock prices of large capitalization companies. These companies
tend to be less well-established than large market capitalization companies. Small capitalization companies may be less able
to withstand adverse economic, market, trade and competitive conditions relative to larger companies. Small capitalization
companies are less likely to pay dividends on their stocks, and the presence of a dividend payment could be a factor that limits downward
stock price pressure under adverse market conditions.

▪ **Our offering of the securities is not a recommendation of any underlying.** The fact that we are offering the securities does
not mean that we believe that investing in an instrument linked to the underlyings is likely to achieve favorable returns. In fact, as
we are part of a global financial institution, our affiliates may have positions (including short positions) in the underlyings or in
instruments related to the underlyings, and may publish research or express opinions, that in each case are inconsistent with an investment
linked to the underlyings. These and other activities of our affiliates may affect the closing values of the underlyings in a way that
negatively affects the value of and your return on the securities.

▪ **The closing value of an underlying may be adversely affected by our or our affiliates' hedging and other trading activities.** We
expect to hedge our obligations under the securities through CGMI or other of our affiliates, who may take positions in the underlyings
or in financial instruments related to the underlyings and may adjust such positions during the term of the securities. Our
affiliates also take positions in the underlyings or in financial instruments related to the underlyings on a regular basis (taking long
or short positions or both), for their accounts, for other accounts under their management or to facilitate transactions on behalf of
customers. These activities could affect the closing values of the underlyings in a way that negatively affects the value of and your
return on the securities. They could also result in substantial returns for us or our affiliates while the value of the securities declines.

▪ **We and our affiliates may have economic interests that are adverse to yours as a result of our affiliates' business activities.** Our affiliates engage in business activities with a wide range of companies. These activities include extending loans, making
and facilitating investments, underwriting securities offerings and providing advisory services. These activities could involve
or affect the underlyings in a way that negatively affects the value of and your return on the securities. They could also result in substantial
returns for us or our affiliates while the value of the securities declines. In addition, in the course of this business, we
or our affiliates may acquire non-public information, which will not be disclosed to you.

▪ **The calculation agent, which is an affiliate of ours, will make important determinations with respect to the securities.** If
certain events occur during the term of the securities, such as market disruption events and other events with respect to an underlying,
CGMI, as calculation agent, will be required to make discretionary judgments that could significantly affect your return on the securities. In
making these judgments, the calculation agent's interests as an affiliate of ours could be adverse to your interests as a holder
of the securities. See "Risk Factors Relating to the Securities—Risk Factors Relating to All Securities—The
calculation agent, which is an affiliate of ours, will make important determinations with respect to the securities" in the accompanying
product supplement.

<u>Citigroup Global Markets Holdings Inc.</u> <br>

▪ **Changes that affect the underlyings may affect the value of your securities.** The sponsors of the underlyings may
at any time make methodological changes or other changes in the manner in which they operate that could affect the values of the underlyings. We
are not affiliated with any such underlying sponsor and, accordingly, we have no control over any changes any such sponsor may make. Such
changes could adversely affect the performance of the underlyings and the value of and your return on the securities.

▪ **The U.S. federal tax consequences of an investment in th e securities ar e unclear.** There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do
not plan to request a ruling from the Internal Revenue Service (the "IRS"). Consequently, significant aspects of
the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the treatment of the securities as prepaid
forward contracts. If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences
of the ownership and disposition of the securities might be materially and adversely affected. Moreover, future legislation,
Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the securities, possibly retroactively.

If you are a non-U.S. investor, you should review the discussion of withholding tax issues in "United States Federal Tax Considerations—Non-U.S. Holders" below.

You should read carefully the discussion under "United States Federal Tax Considerations" and "Risk Factors Relating to the Securities" in the accompanying product supplement and "United States Federal Tax Considerations" in this pricing supplement. You should also consult your tax adviser regarding the U.S. federal tax consequences of an investment in the securities, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

United States Federal Tax Considerations

You should read carefully the discussion under "United States Federal Tax Considerations" and "Risk Factors Relating to the Securities" in the accompanying product supplement and "Summary Risk Factors" in this pricing supplement.

In the opinion of our counsel, Davis Polk & Wardwell LLP, a security should be treated as a prepaid forward contract for U.S. federal income tax purposes. By purchasing a security, you agree (in the absence of an administrative determination or judicial ruling to the contrary) to this treatment. There is uncertainty regarding this treatment, and the IRS or a court might not agree with it. Moreover, our counsel's opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date.

Assuming this treatment of the securities is respected and subject to the discussion in "United States Federal Tax Considerations" in the accompanying product supplement, the following U.S. federal income tax consequences should result under current law:

&nbsp;&nbsp;&nbsp;&nbsp;· You should not recognize taxable income over the term of the securities prior to maturity, other than pursuant to a sale or exchange.

&nbsp;&nbsp;&nbsp;&nbsp;· Upon a sale or exchange of a security (including retirement at maturity), you should recognize capital gain or loss equal to the difference
between the amount realized and your tax basis in the security. Such gain or loss should be long-term capital gain or loss
if you held the security for more than one year.

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. You should consult your tax adviser regarding possible alternative tax treatments of the securities and potential changes in applicable law.

**Non-U.S. Holders**. Subject to the discussions below and in "United States Federal Tax Considerations" in the accompanying product supplement, if you are a Non-U.S. Holder (as defined in the accompanying product supplement) of the securities, you generally should not be subject to U.S. federal withholding or income tax in respect of any amount paid to you with respect to the securities, provided that (i) income in respect of the securities is not effectively connected with your conduct of a trade or business in the United States, and (ii) you comply with the applicable certification requirements.

As discussed under "United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders" in the accompanying product supplement, Section 871(m) of the 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 ("U.S. Underlying Equities") or indices that include U.S. Underlying Equities. Section 871(m) generally applies to instruments that substantially replicate the economic performance of one or more U.S. Underlying Equities, as determined based on tests set forth in the applicable Treasury regulations. However, the 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 the terms of the securities and representations provided by us as of the date of this preliminary pricing supplement, our counsel is of the opinion that the securities should not be treated as transactions that have a "delta" of one within the meaning of the regulations with respect to any U.S. Underlying Equity and, therefore, should not be subject to withholding tax under Section 871(m). However, the final determination regarding the treatment of the securities under Section 871(m) will be made as of the pricing date for the securities, and it is possible that the securities will be subject to withholding tax under Section 871(m) based on the circumstances as of that date.

A determination that the securities are not subject to Section 871(m) is not binding on the IRS, and the IRS may disagree with this treatment. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances, including your other transactions. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

If withholding tax applies to the securities, we will not be required to pay any additional amounts with respect to amounts withheld.

**You should read the section entitled "United States Federal Tax Considerations" in the accompanying product supplement. The preceding discussion, when read in combination with that section, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of owning and disposing of the securities.** 

**You should also consult your tax adviser regarding all aspects of the U.S. federal income and estate tax consequences of an investment in the securities and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.**

Supplemental Plan of Distribution

CGMI, an affiliate of Citigroup Global Markets Holdings Inc. and the underwriter of the sale of the securities, is acting as principal and will not receive any underwriting fee for any securities sold in this offering. However, CGMI and its affiliates may profit from expected hedging activity related to this offering. From these expected hedging profits, CGMI will pay selected dealers participating in the distribution of the securities a structuring fee of up to $8.00 for each security sold in this offering. For the avoidance of doubt, any fees or selling concessions described in this pricing supplement will not be rebated if the securities are automatically redeemed prior to maturity.

See "Plan of Distribution; Conflicts of Interest" in the accompanying product supplement and "Plan of Distribution" in each of the accompanying prospectus supplement and prospectus for additional information.

Valuation of the Securities

CGMI calculated the estimated value of the securities set forth on the cover page of this pricing supplement based on proprietary pricing models. CGMI's proprietary pricing models generated an estimated value for the securities by estimating the value of a hypothetical package of financial instruments that would replicate the payout on the securities, which consists of a fixed-income bond (the "bond component") and one or more derivative instruments underlying the economic terms of the securities (the "derivative component"). CGMI calculated the estimated value of the bond component using a discount rate based on our internal funding rate. CGMI calculated the estimated value of the derivative component based on a proprietary derivative-pricing model, which generated a theoretical price for the instruments that constitute the derivative component based on various inputs, including the factors described under "Summary Risk Factors—The value of the securities prior to maturity will fluctuate based on many unpredictable factors" in this pricing supplement, but not including our or Citigroup Inc.'s creditworthiness. These inputs may be market-observable or may be based on assumptions made by CGMI in its discretionary judgment.

The estimated value of the securities is a function of the terms of the securities and the inputs to CGMI's proprietary pricing models. As of the date of this preliminary pricing supplement, it is uncertain what the estimated value of the securities will be on the pricing date because certain terms of the securities have not yet been fixed and because it is uncertain what the values of the inputs to CGMI's proprietary pricing models will be on the pricing date.

For a period of approximately four months following issuance of the securities, the price, if any, at which CGMI would be willing to buy the securities from investors, and the value that will be indicated for the securities on any brokerage account statements prepared by CGMI or its affiliates (which value CGMI may also publish through one or more financial information vendors), will reflect a temporary upward adjustment from the price or value that would otherwise be determined. This temporary upward adjustment represents a portion of the hedging profit expected to be realized by CGMI or its affiliates over the term of the securities. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the four-month temporary adjustment period. However, CGMI is not obligated to buy the securities from investors at any time. See "Summary Risk Factors—The securities will not be listed on any securities exchange and you may not be able to sell them prior to maturity."
