Geared Buffer Securities Linked to the Worst Performing of the iShares<sup>®</sup> S&P 500 Growth ETF, the Russell 3000<sup>®</sup> Index and the S&P 500 Futures Excess Return Index Due July 23, 2030

▪ 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 and do not repay a fixed amount of principal at maturity. Instead, the securities offer a payment
at maturity that may be greater than, equal to or less than the stated principal amount, depending on the performance of the **worst performing** of the underlyings specified below from its lookback underlying value (as defined below) to its final underlying value.

▪ The S&P 500 Futures Excess Return Index tracks futures contracts
on the S&P 500<sup>®</sup> Index and is expected to underperform the total return performance of the S&P 500<sup>®</sup>
Index because of an implicit financing cost. See "Summary Risk Factors" for more information.

▪ The securities offer modified exposure to the performance of
the worst performing underlying from its lookback underlying value, with (i) the opportunity to participate in any appreciation of the
worst performing underlying above its upside threshold value at the upside participation rate specified below and (ii) a limited buffer
against any depreciation of the worst performing underlying as described below. In exchange for these features, investors in the securities
must be willing to forgo any dividends with respect to any underlying. In addition, investors in the securities must be willing to accept
downside exposure to any depreciation of the worst performing underlying in excess of the buffer percentage specified below. **If the worst performing underlying depreciates by more than the buffer percentage from its lookback underlying value to its final underlying value, you will lose more than 1% of the stated principal amount of your securities for every 1% by which that depreciation exceeds the buffer percentage. Accordingly, the lower the final underlying value, the less benefit you will receive from the buffer percentage. You may lose your entire investment in the securities.** 

▪ You will receive a positive return at maturity only if the worst
performing underlying appreciates by at least 5% from its lookback underlying value to its final underlying value, and any such positive
return will reflect participation in the appreciation of the worst performing underlying from its lookback underlying value at the upside
participation rate only to the extent such appreciation is in excess of 5%. For example, if the worst performing underlying appreciates
by 10% from its lookback underlying value to its final underlying value, you will receive a positive return equal to only 7.05%.

▪ You will be subject to risks associated with each of the underlyings
and will be negatively affected by adverse movements in any one of the underlyings.

▪ In order to obtain the modified exposure to the worst performing
underlying that the securities provide, investors must be willing to accept (i) in the case of the S&P 500 Futures Excess Return
Index, exposure to an index that is expected to underperform the total return of the S&P 500<sup>®</sup> Index, (ii) an investment
that may have limited or no liquidity and (iii) the risk of not receiving any amount 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.**

*(Key Terms continued on next page)*

(1) Citigroup Global Markets Holdings Inc. currently expects that the estimated value of the securities on the pricing date will be at least $908.70 per security, which will be less than the issue price. The estimated value of the securities is based on CGMI's proprietary pricing models and our internal funding rate. It is not an indication of actual profit to CGMI or other of our affiliates, nor is it an indication of the price, if any, at which CGMI or any other person may be willing to buy the securities from you at any time after issuance. See "Valuation of the Securities" in this pricing supplement.

(2) CGMI will receive an underwriting fee of up to $2.00 for each security sold in this offering. The total underwriting fee and proceeds to issuer in the table above give effect to the actual total underwriting fee. For more information on the distribution of the securities, see "Supplemental Plan of Distribution" in this pricing supplement. In addition to the underwriting fee, CGMI and its affiliates may profit from expected hedging activity related to this offering, even if the value of the securities declines. See "Use of Proceeds and Hedging" in the accompanying prospectus.

(3) The per security proceeds to issuer indicated above represent the minimum per security proceeds to issuer for any security, assuming the maximum per security underwriting fee. As noted above, the underwriting fee is variable.

**Investing in the securities involves risks not associated with an investment in conventional debt securities. See "Summary Risk Factors" beginning on page PS-7.**

**Neither the Securities and Exchange Commission (the "SEC") nor any state securities commission has approved or disapproved of the securities or determined that this pricing supplement and the accompanying product supplement, underlying supplement, prospectus supplement and prospectus are truthful or complete.

Hypothetical Examples of Determination of Lookback Underlying Values

The examples below illustrate how the lookback underlying value for each underlying will be determined, assuming the various hypothetical closing values of the underlyings during the lookback observation period indicated below. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of what the actual lookback underlying values of the underlyings will be. The actual lookback underlying values will depend on the actual closing values of the underlyings on each scheduled trading day during the lookback observation period (excluding any scheduled trading day on which a market disruption event occurs).

The examples below are based on the following hypothetical values and do not reflect the actual initial underlying values of the underlyings. The actual initial underlying value for each underlying is set forth on the cover 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 lookback underlying values will be calculated based on the actual initial underlying value of each underlying, and not the hypothetical values indicated below. For ease of analysis, figures below have been rounded.

**Example 1.** A lookback event does not occur because the lookback performance factor of each underlying on each scheduled trading day during the lookback observation period (excluding any scheduled trading day on which a market disruption event occurs) is greater than or equal to 90.00%. The lookback underlying value of each underlying is equal to its initial underlying value.

| S&P 500 Futures Excess Return Index | 100.00 | 90.00 (90.00%) | N/A | 100.00 |

---

**Example 2.** A lookback event does occur because the lookback performance factor of at least one underlying on at least one scheduled trading day during the lookback observation period (excluding any scheduled trading day on which a market disruption event occurs) is less than 90.00%. The lookback underlying value of each underlying is equal to its initial underlying value *multiplied by* the lookback adjustment factor.

Hypothetical Examples of Payment at Maturity

The examples below illustrate how to determine the payment at maturity on the securities, assuming the various hypothetical final underlying values indicated below. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of what the actual payment at maturity on the securities will be. The actual payment at maturity will depend on the actual final underlying value of the worst performing underlying.

The examples below are based on the following hypothetical values and do not reflect the actual lookback underlying values, upside threshold values or final buffer values of the underlyings. The actual lookback underlying value, upside threshold value and final buffer value for each underlying will be determined at the end of the lookback observation period. 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 payment at maturity on the securities will be calculated based on the actual lookback underlying value, upside threshold value and final buffer value of each underlying, and not the hypothetical values indicated below. For ease of analysis, figures below have been rounded.

|:---|:---|:---|:---|
| **Underlying** | **Hypothetical lookback underlying value** | **Hypothetical upside threshold value** | **Hypothetical final buffer value** |
| iShares<sup>®</sup> S&P 500 Growth ETF | $100.00 | $105.00 (105.00% of its hypothetical lookback underlying value) | $80.00 (80.00% of its hypothetical lookback underlying value) |

---

**Example 1—Upside Scenario.** The final underlying value of the worst performing underlying is $110.00, resulting in a 10.00% underlying return for the worst performing underlying. In this example, the final underlying value of the worst performing underlying is **greater than** its upside threshold value.

| **Underlying** | **Hypothetical final underlying value** | **Hypothetical underlying return** |
| iShares<sup>®</sup> S&P 500 Growth ETF\* | $110.00 | 10.00% |

| S&P 500 Futures Excess Return Index | 130.00 | 30.00% |

\* Worst performing underlying

Payment at maturity per security = $1,000 + the return amount

= $1,000 + [$1,000 × (the underlying return of the worst performing underlying – the upside threshold percentage) × the upside participation rate]

= $1,000 + [$1,000 × (10.00% – 5.00%) × 141.00%]

= $1,000 + [$1,000 × 5.00% × 141.00%]

= $1,000 + $70.50

= $1,070.50

In this scenario, the worst performing underlying has appreciated from its lookback underlying value to its final underlying value above its upside threshold value, and your total return at maturity would equal (i) the underlying return of the worst performing underlying *minus* the upside threshold percentage, *multiplied by* (ii) the upside participation rate. Even though the worst performing underlying appreciated by 10% from its lookback underlying value to its final underlying value in this example, your positive return is only 7.05%, reflecting participation at the upside participation rate in the appreciation of the worst performing underlying in excess of its upside threshold value.

**Example 2—Par Scenario A.** The final underlying value of the worst performing underlying is 102.50, resulting in a 2.50% underlying return for the worst performing underlying. In this example, the final underlying value of the worst performing underlying is **less than or equal to** its upside threshold value but **greater than or equal to** its final buffer value.

| iShares<sup>®</sup> S&P 500 Growth ETF | $105.00 | 5.00% |

| S&P 500 Futures Excess Return Index\* | 102.50 | 2.50% |

\* Worst performing underlying

Payment at maturity per security = $1,000

In this scenario, the worst performing underlying has appreciated from its lookback underlying value to its final underlying value, but its final underlying value is less than or equal to its upside threshold value. As a result, you would be repaid the stated principal amount of your securities at maturity but would not receive any positive return on your investment.

Even though the worst performing underlying appreciated by 2.50% from its lookback underlying value to its final underlying value in this example, because the final underlying value is less than the upside threshold value, you will not receive any positive return. As this example illustrates, the worst performing underlying must appreciate by more than the upside threshold percentage from its lookback underlying value to its final underlying value in order for you to receive a positive return at maturity.

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

**Example 3—Par Scenario B.** The final underlying value of the worst performing underlying is 95.00, resulting in a -5.00% underlying return for the worst performing underlying. In this example, the final underlying value of the worst performing underlying is **less than or equal to** its upside threshold value but **greater than or equal to** its final buffer value.

\* Worst performing underlying

Payment at maturity per security = $1,000

In this scenario, the worst performing underlying has depreciated from its lookback underlying value to its final underlying value, but not by more than the buffer percentage. As a result, you would be repaid the stated principal amount of your securities at maturity but would not receive any positive return on your investment.

**Example 4—Downside Scenario A.** The final underlying value of the worst performing underlying is 70.00, resulting in a -30.00% underlying return for the worst performing underlying. In this example, the final underlying value of the worst performing underlying is **less than** its final buffer value.

\* Worst performing underlying

Payment at maturity per security = $1,000 + [$1,000 × the buffer rate × (the underlying return of the worst performing underlying + the buffer percentage)]

= $1,000 + [$1,000 × 1.25 × (-30.00% + 20.00%)]

= $1,000 + [$1,000 × 1.25 × -10.00%]

= $1,000 + -$125.00

= $875.00

In this scenario, the worst performing underlying has depreciated from its lookback underlying value to its final underlying value by more than the buffer percentage. As a result, your total return at maturity in this scenario would be negative and would reflect a loss of more than 1% of the stated principal amount of your securities (at a rate equal to the buffer rate) for every 1% by which the worst performing underlying declined beyond the buffer percentage.

**Example 5—Downside Scenario B.** The final underlying value of the worst performing underlying is 30.00, resulting in a -70.00% underlying return for the worst performing underlying. In this example, the final underlying value of the worst performing underlying is **less than** its final buffer value.

\* Worst performing underlying

Payment at maturity per security = $1,000 + [$1,000 × the buffer rate × (the underlying return of the worst performing underlying + the buffer percentage)]

= $1,000 + [$1,000 × 1.25 × (-70.00% + 20.00%)]

= $1,000 + [$1,000 × 1.25 × -50.00%]

= $1,000 + -$625.00

= $375.00

In this scenario, the worst performing underlying has depreciated from its lookback underlying value to its final underlying value by more than the buffer percentage. As a result, your total return at maturity in this scenario would be negative and would reflect a loss of more than 1% of the stated principal amount of your securities (at a rate equal to the buffer rate) for every 1% by which the worst performing underlying declined beyond the buffer percentage. A comparison of this example with the previous example illustrates the diminishing benefit of the buffer the greater the depreciation of the worst performing underlying. The greater the depreciation of the worst performing underlying, the closer your negative return on the securities will be to the depreciation of the worst performing underlying.

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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **You may lose a significant portion or all of your investment.** Unlike conventional debt securities, the securities do not repay
a fixed amount of principal at maturity. Instead, your payment at maturity will depend on the performance of the worst performing underlying.
If the worst performing underlying depreciates by more than the buffer percentage from its lookback underlying value to its final underlying
value, you will lose more than 1% of the stated principal amount of your securities for every 1% by which that depreciation exceeds the
buffer percentage. You should understand that any depreciation of the worst performing underlying in excess of the buffer percentage will
result in a magnified loss to your investment at a rate equal to the buffer rate, which will progressively offset any protection that
the buffer percentage would offer. The lower the final underlying value of the worst performing underlying, the less benefit you will
receive from the buffer percentage. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **The initial underlying values, set on the strike date, may be higher or lower than the closing values of the underlyings on the pricing date.** If the closing values of the underlyings on the pricing date are higher or lower than the initial underlying values set
on the strike date, the terms of the securities may be less favorable to you than the terms of an alternative investment that may be available
to you that offers a similar payout as the securities but with the initial underlying values set on the pricing date.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **The payment at maturity will be greater than the principal amount only if the final underlying value is greater than the upside threshold value.** You will not participate in any appreciation in the worst performing underlying from its lookback underlying value
unless the worst performing underlying appreciates by at least 5% from its lookback underlying value to its final underlying value. Further,
your participation in any such appreciation at the upside participation rate will be limited to the extent that such appreciation is in
excess of 5%. For example, if the worst performing underlying appreciates by 10% from its lookback underlying value, you will receive
a positive return equal to 5% *multiplied by* the upside participation rate, or 7.05%. Any positive return on the securities may
be less than the return that you could have achieved on an alternative investment providing 1-to-1 exposure to the upside performance
of the worst performing underlying.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **The securities do not pay interest.** Unlike conventional debt securities, the securities do not pay interest or any other amounts
prior to maturity. You should not invest in the securities if you seek current income during the term of the securities.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Your payment at maturity depends on the closing value of the worst performing underlying on a single day.** Because your payment
at maturity depends on the closing value of the worst performing underlying solely on the valuation date, you are subject to the risk
that the closing value of the worst performing underlying on that day may be lower, and possibly significantly lower, than on one or more
other dates during the term of the securities. If you had invested in another instrument linked to the worst performing underlying that

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

you could sell for full value at a time selected by you, or if the payment at maturity were based on an average of closing values of the worst performing underlying, you might have achieved better returns.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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 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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **The investment strategy represented by the iShares<sup>®</sup> S&P 500 Growth ETF may not be successful** — The
iShares<sup>®</sup> S&P 500 Growth ETF seeks to track the investment results, before fees and expenses, of an index composed of
large-capitalization U.S. equities that exhibit growth characteristics, which is currently the S&P 500<sup>®</sup> Growth Index.
The S&P 500<sup>®</sup> Growth Index is a float-adjusted market capitalization-weighted index that is designed to measure the
full performance of companies included in the S&P 500<sup>®</sup> Index that exhibit relatively strong growth characteristics
(determined by reference to earnings-per-share growth, sales-per-share growth and upward share price momentum) and relatively weak value
characteristics (determined by reference to book-value-to-price ratio, earnings-to-price ratio and sales-to-price ratio) and a portion
of the performance of companies with more balanced growth and value characteristics (where greater weight is allocated to companies with
relatively stronger growth characteristics and relatively weaker value characteristics). A "growth" investment strategy is
premised on the goal of investing in stocks of companies whose earnings are expected to increase at an above-average rate compared to
their industry sector or the overall market. However, the growth characteristics referenced by the S&P 500<sup>®</sup> Growth
Index may not be accurate predictors of growth stocks, and there is no guarantee that growth stocks will appreciate. Moreover, the selection
methodology for the S&P 500<sup>®</sup> Growth Index includes a significant bias against stocks with strong value characteristics,
and stocks with strong value characteristics may outperform stocks with weak value characteristics.

Even if a growth strategy with respect to the stocks included in the S&P 500<sup>®</sup> Growth Index would generally be successful, the manner in which the S&P 500<sup>®</sup> Growth Index implements its strategy may prove to be unsuccessful. The methodology of the S&P 500<sup>®</sup> Growth Index has set parameters to determine whether a stock should be considered a "growth" stock. The S&P 500<sup>®</sup> Growth Index's parameters may not effectively implement its growth strategy, and there can be no assurance that it will select stocks that are growth oriented, that the S&P 500<sup>®</sup> Growth Index's methodology will not underperform any alternative implementation of such a strategy, or that the iShares<sup>®</sup> S&P 500 Growth ETF will outperform any other exchange-traded fund or any index or strategy that tracks U.S. stocks selected using other criteria. Stocks that are considered to be growth-oriented may have lower value potential than other securities, which may cause the price of the iShares<sup>®</sup> S&P 500 Growth ETF to decrease over the term of the notes. Accordingly, the investment strategy represented by the iShares<sup>®</sup> S&P 500 Growth ETF may not be successful, and your investment in the notes may result in a loss. An investment in the notes may also provide a return that is less than an investment linked to the iShares<sup>®</sup> S&P 500 Growth ETF as a whole.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **The S&P 500 Futures Excess Return Index is expected to underperform the total return performance of the S&P 500<sup>®</sup> Index because the performance of the S&P 500 Futures Excess Return Index is expected to be reduced by an implicit financing cost, and any increase in this cost will adversely affect the performance of the securities.** The S&P 500 Futures Excess Return Index is a futures-based index. As a futures-based index, it is expected to reflect not only the
performance of its reference index (the S&P 500<sup>®</sup> Index), but also the implicit cost of a financed position in that
reference index. The cost of this financed position will adversely affect the value of the underlying. Any increase in market interest
rates will be expected to further increase this implicit financing cost and will increase the negative effect on the performance of the
underlying. Because of this implicit financing cost, the S&P 500 Futures Excess Return Index is expected to underperform the total
return performance of the S&P 500<sup>®</sup> Index.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **In the case of an underlying that is an underlying ETF, even if the underlying pays a dividend that it identifies as special or extraordinary, no adjustment will be required under the securities for that dividend unless it meets the criteria specified in the accompanying product supplement.** In general, an adjustment will not be made under the terms of the securities for any cash dividend paid by the
underlying unless the amount of the dividend per share, together with any other dividends paid in the same quarter, exceeds the dividend
paid per share in the most recent quarter by an amount equal to at least 10% of the closing value of that underlying on the date of declaration
of the dividend. Any dividend will reduce the closing value of the underlying by the amount of the dividend per share. If the underlying
pays any dividend for which an adjustment is not made under the terms of the securities, holders of the securities will be adversely affected.
See "Description of the Securities—Certain Additional Terms for Securities Linked to an Underlying Company or an Underlying
ETF—Dilution and Reorganization Adjustments—Certain Extraordinary Cash Dividends" in the accompanying product supplement.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **In the case of an underlying that is an underlying ETF, the securities will not be adjusted for all events that may have a dilutive effect on or otherwise adversely affect the closing value of the underlying.** For example, we will not make any adjustment for ordinary
dividends or extraordinary dividends that do not meet the criteria described above, partial tender offers or additional underlying share
issuances. Moreover, the adjustments we do make may not fully offset the dilutive or adverse effect of the particular event. Investors
in the securities may be adversely affected by such an event in a circumstance in which a direct holder of the underlying shares of the
underlying would not.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **In the case of an underlying that is an underlying ETF, the securities may become linked to an underlying other than the original underlying upon the occurrence of a reorganization event or upon the delisting of the underlying shares of that original underlying.** For
example, if the underlying enters into a merger agreement that provides for holders of its underlying shares to receive shares of another
entity and such shares are marketable securities, the closing value of that underlying following consummation of the merger will be based
on the value of such other shares. Additionally, if the underlying shares of the underlying are delisted, the calculation agent may select
a successor underlying. See "Description of the Securities—Certain Additional Terms for Securities Linked to an Underlying
Company or an Underlying ETF" in the accompanying product supplement.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **In the case of the underlying that is an underlying ETF, the value and performance of the underlying shares of the underlying may not completely track the performance of the underlying index that the underlying seeks to track or the net asset value per share of the underlying.** In the case of the underlying that is an underlying ETF, the underlying does not fully replicate the underlying index
that it seeks to track and may hold securities different from those included in its underlying index. In addition, the performance of
the underlying will reflect additional transaction costs and fees that are not included in the calculation of its underlying index. All
of these factors may lead to a lack of correlation between the performance of the underlying and its underlying index. In addition, corporate
actions with respect to the equity securities held by the underlying (such as mergers and spin-offs) may impact the variance between the
performance of the underlying and its underlying index. Finally, because the underlying shares are traded on an exchange and are subject
to market supply and investor demand, the closing value of the underlying may differ from the net asset value per share of the underlying.

During periods of market volatility, securities included in the underlying's underlying index may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of the underlying and the liquidity of the underlying may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares of the underlying. Further, market volatility may adversely affect, sometimes materially, the price at which market participants are willing to buy and sell the underlying shares. As a result, under these circumstances, the closing value of the underlying may vary substantially from the net asset value per share of the underlying. For all of the foregoing reasons, the performance of the underlying may not correlate with the performance of its underlying index and/or its net asset value per share, which could materially and adversely affect the value of the securities and/or reduce your return on the securities.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **The U.S. federal tax consequences of an investment in the securities are 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.
Even if the treatment of the securities as prepaid forward contracts is respected, a security may be treated as a "constructive
ownership transaction," with potentially adverse consequences described below under "United States Federal Tax Considerations."
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.

Information About the iShares<sup>®</sup> S&P 500 Growth ETF

The iShares<sup>®</sup> S&P 500 Growth ETF is an exchange-traded fund that seeks to track the investment results, before fees and expenses, of an index composed of large-capitalization U.S. equities that exhibit growth characteristics, which is currently the S&P 500<sup>®</sup> Growth Index.

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 gain or loss equal to the difference
between the amount realized and your tax basis in the security. Subject to the discussion below concerning the potential application
of the "constructive ownership" rules under Section 1260 of the Code, any gain or loss recognized upon a sale, exchange or
retirement of a security should be long-term capital gain or loss if you held the security for more than one year.

Even if the treatment of the securities as prepaid forward contracts is respected, your purchase of a security may be treated as entry into a "constructive ownership transaction," within the meaning of Section 1260 of the Code. In that case, all or a portion of any long-term capital gain you would otherwise recognize in respect of your securities would be recharacterized as ordinary income to the extent such gain exceeded the "net underlying long-term capital gain." Any long-term capital gain recharacterized as ordinary income under Section 1260 would be treated as accruing at a constant rate over the period you held your securities, and you would be subject to an interest charge in respect of the deemed tax liability on the income treated as accruing in prior tax years. Due to the lack of governing authority under Section 1260, our counsel is not able to opine as to whether or how Section 1260 applies to the securities. You should read the section entitled "United States Federal Tax Considerations—Tax Consequences to U.S. Holders—Securities Treated as Prepaid Forward Contracts—Possible Application of Section 1260 of the Code" in the accompanying product supplement for additional information and consult your tax adviser regarding the potential application of the "constructive ownership" rule.

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 receive an underwriting fee of up to $2.00 for each security sold in this offering. The actual underwriting fee will be equal to the selling concession provided to selected dealers, as described in this paragraph. From this underwriting fee, CGMI will pay selected dealers not affiliated with CGMI a variable selling concession of up to $2.00 for each security they sell. For the avoidance of doubt, the fees and 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 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."

**Annex A<br> Description of the S&P 500 Futures Excess Return Index**

We have derived all information contained in this pricing supplement regarding the S&P 500 Futures Excess Return Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. We have not independently verified such information. Such information reflects the policies of, and is subject to change by, S&P Dow Jones Indices LLC ("S&P Dow Jones"). The S&P 500 Futures Excess Return Index was developed by Standard & Poor's Financial Services LLC ("S&P") and is calculated, maintained and published by S&P Dow Jones. S&P Dow Jones has no obligation to continue to publish, and may discontinue the publication of, the S&P 500 Futures Excess Return Index.

The S&P 500 Futures Excess Return Index tracks futures contracts on the S&P 500<sup>®</sup> Index. The S&P 500<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "SPX." The S&P 500<sup>®</sup> Index consists of the common stocks of 500 issuers selected to provide a performance benchmark for the large capitalization segment of the U.S. equity market. For more information about the S&P 500<sup>®</sup> Index, see "Equity Index Descriptions—The S&P U.S. Indices" in the accompanying underlying supplement. We refer to the S&P 500<sup>®</sup> Index as the "reference index" for the S&P 500 Futures Excess Return Index.

The S&P 500 Futures Excess Return Index is a futures-based index. As a futures-based index, it is expected to reflect not only the performance of its reference index (the S&P 500<sup>®</sup> Index), but also the implicit cost of a financed position in that reference index. The cost of this financed position will adversely affect the value of the S&P 500 Futures Excess Return Index. Any increase in market interest rates will be expected to further increase this implicit financing cost and will increase the negative effect on the performance of the S&P 500 Futures Excess Return Index. Because of this implicit financing cost, the S&P 500 Futures Excess Return Index is expected to underperform the total return performance of the S&P 500<sup>®</sup> Index.

The S&P 500 Futures Excess Return Index launch date was August 2, 2010, and it is reported by Bloomberg L.P. under the ticker symbol "SPXFP."

***Index Calculation***

The S&P 500 Futures Excess Return Index tracks the performance of a hypothetical position, rolled quarterly, in the nearest-to-expiration E-mini S&P 500 futures contract. Constructed from E-mini S&P 500 futures contracts, the S&P 500 Futures Excess Return Index includes provisions for the replacement of the current E-mini S&P 500 futures contract in the S&P 500 Futures Excess Return Index as such futures contract approaches expiration (also referred to as "rolling"). This replacement occurs over a one-day rolling period every quarter, which is five days prior to the last trade date of the futures contract.

The S&P 500 Futures Excess Return Index is calculated from the price change of the underlying E-mini S&P 500 futures contract. On any trading date, *t*, the value of the S&P 500 Futures Excess Return Index is calculated as follows:

![Formula:Indext=Indext-1??(1+CDRt,t-1)](image_005.jpg)

Where:

---

| | | |
|:---|:---|:---|
| ![Formula:Indext](image_006.jpg) | = | The value of the S&P 500 Futures Excess Return Index on the current day, *t* |
| ![Formula:Indext-1](image_007.jpg) | = | The value of the S&P 500 Futures Excess Return Index on the preceding day on which the S&P 500 Futures Excess Return Index was calculated, *t-1* |
| ![Formula:CDRt,t-1](image_008.jpg) | = | The Contract Daily Return from day *t-1* to day *t,* defined as:<br> ![Formula:DCRPtDCRPt-1-1](image_009.jpg) |
| ![Formula:DCRP](image_010.jpg) | = | The daily contract reference price of the futures contract, which is the official closing price, as designated by the exchange |

---

Market disruptions are situations where the exchange has failed to open so that no trading is possible due to unforeseen events, such as computer or electric power failures, weather conditions or other events. If any such event happens on the roll date, the roll will take place on the next business day on which no market disruptions exist.

The S&P 500 Futures Excess Return Index is an excess return index, which in this context means that its performance will be based solely on changes in the settlement price of its underlying futures contract. An excess return index is distinct from a total return index, which, in addition to changes in the settlement price of the underlying futures contract, would reflect interest on a hypothetical cash position collateralizing that futures contract.

***E-mini S&P 500 futures contracts***

E-mini S&P 500 futures contracts were introduced in 1997 and are traded on the Chicago Mercantile Exchange under the ticker symbol "ES." The Chicago Mercantile Exchange trades E-mini S&P 500 futures contracts with expiration dates in March, June, September and December of each year.

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

E-mini S&P 500 futures contracts differ from the futures contracts described below under "—Futures Contracts Generally" in that E-mini S&P 500 futures contracts are cash settled only, meaning that the 500 stocks composing the S&P 500<sup>®</sup> Index are not actually delivered upon settlement of the futures contract. Therefore, the E-mini S&P 500 futures contracts are not contracts to actually buy and sell the stocks in the S&P 500<sup>®</sup> Index. In all other relevant respects, however – including daily "mark to market" and realization of gains or losses based on the difference between the current settlement price and the initial futures price – the E-mini S&P 500 futures contracts are similar to those described below under "—Futures Contracts Generally."

***Futures Contracts Generally***

Generally speaking, a futures contract is an agreement to buy or sell an underlying asset on a future expiration date at a price that is agreed upon today. If the underlying asset is worth more on the expiration date than the price specified in the futures contract, then the purchaser of that contract will achieve a gain on that contract, and if it is worth less, the purchaser will incur a loss.

For example, suppose that a futures contract entered into in January calls for the purchaser to buy the underlying asset in April at a price of $1,000. If the underlying asset is worth $1,200 in April, then upon settlement of the futures contract in April the purchaser will buy for $1,000 an underlying asset worth $1,200, achieving a $200 gain. Conversely, if the underlying asset is worth $800 in April, then upon settlement of the futures contract in April the purchaser will buy for $1,000 an underlying asset worth only $800, incurring a $200 loss.

The gain or loss to the purchaser of this futures contract is different from the gain or loss that could have been achieved by the direct purchase of the underlying asset in January and the sale of that underlying asset in April. This is because a futures contract is a "leveraged" way to invest in the underlying asset. In other words, purchasing a futures contract is similar to borrowing money to buy the underlying asset, in that (i) it enables an investor to gain exposure to the underlying asset without having to pay the full cost of it up front and (ii) it entails a financing cost.

This financing cost is implicit in the difference between the spot price of the underlying asset and the futures price. A "futures price" is the price at which market participants may agree today to buy or sell the underlying asset in the future, and the "spot price" is the current price of the underlying asset for immediate delivery. The futures price is determined by market supply and demand and is independent of the spot price, but it is nevertheless generally expected that the futures price will be related to the spot price in a way that reflects a financing cost (because if it did not do so there would be an opportunity for traders to make sure profits, known as "arbitrage"). For example, if January's futures price is $1,000, January's spot price may be $975. If the underlying asset is worth $1,200 in April, the gain on the futures contract would be $200 ($1,200 minus $1,000), while the gain on a direct investment made at the January spot price would have been $225 ($1,200 minus $975). The lower return on the futures contract as compared to the direct investment reflects this implicit financing cost. Because of this financing cost, it is possible for a purchaser to incur a loss on a futures contract even if the spot price of the underlying asset increases over the term of the futures contract. The amount of this financing cost is expected to increase as general market interest rates increase.

Futures contracts are standardized instruments that are traded on an exchange. On each trading day, the exchange determines a settlement price (which may also be referred to as a closing price) for that futures contract based on the futures prices at which market participants entered into that futures contract on that day. Open positions in futures contracts are "marked to market" and margin is required to be posted on each trading day. This means that, on each trading day, the current settlement price for a futures contract is compared to the futures price at which the purchaser entered into that futures contract. If the current settlement price has decreased from the initial futures price, then the purchaser will be required to deposit the decrease in value of that futures contract into an account. Conversely, if the current settlement price has increased, the purchaser will receive that cash value in its account. Accordingly, gains or losses on a futures contract are effectively realized on a daily basis up until the point when the position in that futures contract is closed out.

Because futures contracts have expiration dates, one futures contract must be rolled into another if there is a desire to maintain a continuous position in futures contracts on (rather than take delivery of) a particular underlying asset. This is typically achieved by closing out the position in the existing futures contract as its expiration date approaches and simultaneously entering into a new futures contract (at a new futures price based on the futures price then prevailing) with a later expiration date.

***Comparison of Historical S&P 500 Futures Excess Return Index Performance Against Historical S&P 500<sup>®</sup> Index Performance***

The following graph sets forth a comparison of the historical performance of the S&P 500 Futures Excess Return Index against the historical performance of the S&P 500<sup>®</sup> Index from January 2, 2015 through July 17, 2025, each normalized to have a closing value of 100.00 on January 2, 2015 to facilitate a comparison. The performance of the S&P 500<sup>®</sup> Index shown below is its price return performance – i.e., its performance without reflecting dividends. The total return performance of the S&P 500<sup>®</sup> Index (i.e., its performance reflecting dividends) would be greater than the price return performance shown below.
