Citigroup Global Markets Holdings Inc. April 29, 2024 Medium-Term Senior Notes, Series N Pricing Supplement No. 2024-USNCH21697 Filed Pursuant to Rule 424(b)(2) Registration Statement Nos. 333-270327 and 333-270327-01

Dual Directional Market-Linked Notes Linked to the S&P 500^® Index Due May 6, 2026

Overview

▪ The notes 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 notes do not pay interest. Instead, the notes offer the potential for a positive return at maturity based on the performance of the underlying index specified below over the term of the notes.

▪ The notes offer the potential for positive participation in the absolute value of the performance of the underlying index from its initial index level to its final index level, subject to the minimum return specified below, but only so long as a knock-out event does not occur. A knock-out event will occur if the intra-day level of the underlying index at any time on any scheduled trading day during the observation period specified below is equal to or less than the downside knock-out level or equal to or greater than the upside knock-out level specified below. If a knock-out event occurs, you will be repaid the stated principal amount of your notes at maturity plus the minimum return. As the notes do not pay any interest and you will not receive any dividends on the underlying index, there is no assurance that your total return at maturity on the notes will compensate you for the effects of inflation or be as great as the yield you could have achieved on a conventional debt security of ours of comparable maturity.

▪ To obtain the modified exposure to the underlying index that the notes provide, investors must be willing to accept (i) an investment that may have limited or no liquidity and (ii) the risk of not receiving any amount due under the notes if we and Citigroup Inc. default on our obligations. All payments on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.

Hypothetical Examples

The table below indicates what your payment at maturity and total return on the notes would be for various hypothetical index returns of the underlying index, depending on whether a knock-out event has occurred. Your actual payment at maturity per note and total return on the notes will depend on the actual index return and whether a knock-out event actually occurs.

The examples below are intended to illustrate how your payment at maturity will depend on whether a knock-out event occurs and, if a knock-out event does not occur, on the index return of the underlying index. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of what your actual payment at maturity on the notes will be. The examples are based on a hypothetical initial index level of 100.00 and do not reflect the actual initial index level. For the actual initial index level, see the cover page of this pricing supplement. We have used this hypothetical level, rather than the actual level, to simplify the calculations and aid understanding of how the notes work. However, you should understand that your actual payment at maturity will be calculated based on the actual initial index level, and not the hypothetical initial index level used in the examples below.

Example 1. A knock-out event does not occur, and the hypothetical final index level is 102.00, resulting in an index return of 2.00%.

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

= $1,000 + [$1,000 × the greater of (i) the minimum return and (ii) the absolute value of the index return]

= $1,000 + ($1,000 × the minimum return)

= $1,000 + ($1,000 × 5.00%)

= $1,000 + $50.00

= $1,050.00

PS-3

Because a knock-out event did not occur in this example and the absolute value of the index return is less than the minimum return, you would receive a return equal to the minimum return.

Example 2. A knock-out event does not occur, and the hypothetical final index level is 90.00, resulting in an index return of

-10.00%.

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

= $1,000 + [$1,000 × the greater of (i) the minimum return and (ii) the absolute value of the index return]

= $1,000 + ($1,000 × the absolute value of the index return)

= $1,000 + ($1,000 × | -10.00% |)

= $1,000 + $100.00

= $1,100.00

Because a knock-out event did not occur in this example and the absolute value of the index return is greater than the minimum return, you would participate on a 1-to-1 basis in the absolute value of the depreciation of the underlying index from the initial index level to the final index level.

Example 3. A knock-out event occurs, and the hypothetical final index level is 150.00, resulting in an index return of 50.00%.

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

= $1,000 + ($1,000 × the minimum return)

= $1,000 + ($1,000 × 5.00%)

= $1,000 + $50.00

= $1,050.00

Because a knock-out event occurred in this example, you would be repaid the stated principal amount of your notes at maturity plus the minimum return. In this example, you would not participate in the significant appreciation of the underlying index over the term of the notes.

Summary Risk Factors

An investment in the notes is significantly riskier than an investment in conventional debt securities. The notes 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 notes, and are also subject to risks associated with the underlying index. Accordingly, the notes are suitable only for investors who are capable of understanding the complexities and risks of the notes. You should consult your own financial, tax and legal advisors as to the risks of an investment in the notes and the suitability of the notes in light of your particular circumstances.

The following is a summary of certain key risk factors for investors in the notes. You should read this summary together with the more detailed description of risks relating to an investment in the notes contained in the section “Risk Factors Relating to the Notes” beginning on page EA-6 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.

▪ You may not receive any positive return on your investment in the notes in excess of the minimum return. The notes do not pay interest. Even if you do receive a positive return at maturity in excess of the minimum return, there is no assurance that your total return on the notes will be as great as could have been achieved on a conventional debt security of ours of comparable maturity. The notes are not appropriate for investors who require interest payments or the certainty of a positive return on their investment in excess of the minimum return.

▪ The initial index level, set on the strike date, may be higher than the closing level of the underlying index on the pricing date. If the closing level of the underlying index on the pricing date is less than the initial index level set on the strike date, the terms of the notes 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 notes but with the initial index level set on the pricing date.

▪ Although the notes provide for the repayment of the stated principal amount at maturity, you may nevertheless suffer a loss on your investment in real value terms if a knock-out event occurs or if the underlying index does not appreciate or depreciate sufficiently from the initial index level to the final index level. This is because inflation may cause the real value of the stated principal amount to be less at maturity than it is at the time you invest, and because an investment in the notes represents a forgone opportunity to invest in an alternative asset that does generate a positive real return at a market rate. You should carefully consider whether an investment that may not provide for any return on your investment, or may provide a return that is lower than the return on alternative investments, is appropriate for you.

▪ Your potential to participate in the absolute value of the performance of the underlying index may terminate at any time on any scheduled trading day during the observation period. A knock-out event will occur if the intra-day level of the underlying index at any time on any scheduled trading day during the observation period is equal to or less than the downside knock-out level or equal to or greater than the upside knock-out level. A knock-out event may occur even if only as a result of a temporary rise or drop in the intra-day level of the underlying index that is quickly reversed. The knock-out feature of the notes effectively limits the potential return on the notes.

▪ The probability that a knock-out event will occur will depend in part on the volatility of the underlying index. “Volatility” refers to the frequency and magnitude of changes in the level of the underlying index. In general, the greater the volatility of the underlying index, the greater the probability that the underlying index will experience a large increase or decrease over the term of the notes and a knock-out event will occur at any time on any scheduled trading day during the observation period. The underlying index has historically experienced significant volatility. As a result, there is a significant risk that a knock-out event will occur during the observation period. The terms of the notes are set, in part, based on expectations about the volatility of the underlying index as of the pricing date. If expectations about the volatility of the underlying index change over the term of the notes, the value of the notes may be adversely affected, and if the actual volatility of the underlying index proves to be greater than initially expected, the notes may prove to be riskier than initially expected.

▪ Your potential return on the notes is limited and may significantly underperform the underlying index. The notes offer the potential for (i) a positive return at maturity based on the greater of the minimum return and the absolute value of the performance of the underlying index if a knock-out event does not occur and (ii) a positive fixed return at maturity if a knock-out event does occur. A knock-out event will occur if the intra-day level of the underlying index at any time on any scheduled trading day during the observation period is equal to or less than the downside knock-out level or equal to or greater than the upside knock-out level. If the intra-day level of the underlying index at any time on any scheduled trading day during the observation period is equal to or greater than the upside knock-out level, you will not participate in any appreciation of the underlying index. As a result, your potential return on the notes may be significantly less than the return you could have achieved by investing directly in the underlying index.

▪ Investing in the notes is not equivalent to investing in the underlying index or the stocks that constitute the underlying index. You will not have voting rights, rights to receive dividends or other distributions or any other rights with respect to the stocks that constitute the underlying index. The payment scenarios described in this pricing supplement do not show any effect of lost

PS-5

Citigroup Global Markets Holdings Inc.

dividend yield over the term of the notes. If the underlying index appreciates, or if it depreciates by up to the dividend yield, this lost dividend yield will cause the notes to underperform an alternative investment providing for a pass-through of all dividends and 1-to-1 exposure to the performance of the underlying index.

▪ If a knock-out event does not occur, your payment at maturity will depend on the closing level of the underlying index on a single day. Because your payment at maturity will depend on the closing level of the underlying index solely on the valuation date if a knock-out event does not occur, you are subject to the risk that the closing level of the underlying index on that day may result in a lower, and possibly significantly lower, payment at maturity than the closing level on one or more other dates during the term of the notes. If the payment at maturity were based on an average of closing levels of the underlying index, you might have achieved better returns.

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

▪ The notes will not be listed on any securities exchange and you may not be able to sell them prior to maturity. The notes will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the notes. CGMI currently intends to make a secondary market in relation to the notes and to provide an indicative bid price for the notes on a daily basis. Any indicative bid price for the notes 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 notes 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 notes because it is likely that CGMI will be the only broker-dealer that is willing to buy your notes prior to maturity. Accordingly, an investor must be prepared to hold the notes until maturity.

▪ Sale of the notes prior to maturity may result in a loss of principal. You will be entitled to receive at least the full stated principal amount of your notes, subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., only if you hold the notes to maturity. The value of the notes may fluctuate during the term of the notes, and if you are able to sell your notes prior to maturity, you may receive less than the full stated principal amount of your notes.

▪ The estimated value of the notes 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 notes that are included in the issue price. These costs include (i) the selling concessions paid in connection with the offering of the notes, (ii) hedging and other costs incurred by us and our affiliates in connection with the offering of the notes 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 notes. These costs adversely affect the economic terms of the notes because, if they were lower, the economic terms of the notes would be more favorable to you. The economic terms of the notes are also likely to be adversely affected by the use of our internal funding rate, rather than our secondary market rate, to price the notes. See “The estimated value of the notes would be lower if it were calculated based on our secondary market rate” below.

▪ The estimated value of the notes 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 the underlying index, dividend yields on the stocks that constitute the underlying index 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 notes. Moreover, the estimated value of the notes set forth on the cover page of this pricing supplement may differ from the value that we or our affiliates may determine for the notes for other purposes, including for accounting purposes. You should not invest in the notes because of the estimated value of the notes. Instead, you should be willing to hold the notes to maturity irrespective of the initial estimated value.

▪ The estimated value of the notes would be lower if it were calculated based on our secondary market rate. The estimated value of the notes 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 notes. 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 notes for purposes of any purchases of the notes 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 notes, 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 we will pay to investors in the notes.

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 notes, 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

PS-6

Citigroup Global Markets Holdings Inc.

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 notes prior to maturity.

▪ The estimated value of the notes is not an indication of the price, if any, at which CGMI or any other person may be willing to buy the notes from you in the secondary market. Any such secondary market price will fluctuate over the term of the notes 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 notes 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 notes than if our internal funding rate were used. In addition, any secondary market price for the notes will be reduced by a bid-ask spread, which may vary depending on the aggregate stated principal amount of the notes 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 notes will be less than the issue price.

▪ The value of the notes prior to maturity will fluctuate based on many unpredictable factors. The value of your notes prior to maturity will fluctuate based on the level and volatility of the underlying index and a number of other factors, including the price and volatility of the stocks that constitute the underlying index, the dividend yields on the stocks that constitute the underlying index, interest rates generally, the time remaining to maturity and our and Citigroup Inc.’s creditworthiness, as reflected in our secondary market rate. Changes in the level of the underlying index may not result in a comparable change in the value of your notes. You should understand that the value of your notes 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 Notes” in this pricing supplement.

▪ Our offering of the notes does not constitute a recommendation of the underlying index. The fact that we are offering the notes does not mean that we believe that investing in an instrument linked to the underlying index 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 stocks that constitute the underlying index or in instruments related to the underlying index or such stocks, and may publish research or express opinions, that in each case are inconsistent with an investment linked to the underlying index. These and other activities of our affiliates may affect the level of the underlying index in a way that has a negative impact on your interests as a holder of the notes.

▪ The level of the underlying index may be adversely affected by our or our affiliates’ hedging and other trading activities. We have hedged our obligations under the notes through CGMI or other of our affiliates, who have taken positions directly in the stocks that constitute the underlying index and other financial instruments related to the underlying index or such stocks and may adjust such positions during the term of the notes. Our affiliates also trade the stocks that constitute the underlying index and other financial instruments related to the underlying index or such stocks 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 level of the underlying index in a way that negatively affects the value of the notes. They could also result in substantial returns for us or our affiliates while the value of the notes declines.

▪ We and our affiliates may have economic interests that are adverse to yours as a result of our affiliates’ business activities. Our affiliates may currently or from time to time engage in business with the issuers of the stocks that constitute the underlying index, including extending loans to, making equity investments in or providing advisory services to such issuers. In the course of this business, we or our affiliates may acquire non-public information about such issuers, which we will not disclose to you. Moreover, if any of our affiliates is or becomes a creditor of any such issuer, they may exercise any remedies against such issuer that are available to them without regard to your interests.

▪ The calculation agent, which is an affiliate of ours, will make important determinations with respect to the notes. If certain events occur, such as market disruption events or the discontinuance of the underlying index, CGMI, as calculation agent, will be required to make discretionary judgments that could significantly affect your payment at maturity. 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 notes.

▪ Adjustments to the underlying index may affect the value of your notes. The publisher of the underlying index may add, delete or substitute the stocks that constitute the underlying index or make other methodological changes that could affect the level of the underlying index. The publisher of the underlying index may discontinue or suspend calculation or publication of the underlying index at any time without regard to your interests as holders of the notes.

In the opinion of our counsel, Davis Polk & Wardwell LLP, which is based on current market conditions, the notes should be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, as described in the section of the accompanying product supplement called “United States Federal Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Contingent Payment Debt Instruments,” and the remaining discussion is based on this treatment.

If you are a U.S. Holder (as defined in the accompanying product supplement), you will be required to recognize interest income during the term of the notes at the “comparable yield,” which generally is the yield at which we could issue a fixed-rate debt instrument with terms similar to those of the notes, including the level of subordination, term, timing of payments and general market conditions, but excluding any adjustments for the riskiness of the contingencies or the liquidity of the notes. We are required to construct a “projected payment schedule” in respect of the notes representing a payment the amount and timing of which would produce a yield to maturity on the notes equal to the comparable yield. Assuming you hold the notes until their maturity, the amount of interest you include in income based on the comparable yield in the taxable year in which the notes mature will be adjusted upward or downward to reflect the difference, if any, between the actual and projected payment on the notes at maturity as determined under the projected payment schedule.

Upon the sale, exchange or retirement of the notes prior to maturity, you generally will recognize gain or loss equal to the difference between the proceeds received and your adjusted tax basis in the notes. Your adjusted tax basis will equal your purchase price for the notes, increased by interest previously included in income on the notes. Any gain generally will be treated as ordinary income, and any loss generally will be treated as ordinary loss to the extent of prior interest inclusions on the note and as capital loss thereafter.

We have determined that the comparable yield for a note is a rate of 5.465%, compounded semi-annually, and that the projected payment schedule with respect to a note consists of a single payment of $1,114.032 at maturity.

Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount that we will pay on the notes.

Non-U.S. Holders. Subject to the discussions below regarding Section 871(m) and in “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders” and “—FATCA” in the accompanying product supplement, if you are a Non-U.S. Holder (as defined in the accompanying product supplement) of the notes, under current law you generally will not be subject to U.S. federal withholding or income tax in respect of any payment on or any amount received on the sale, exchange or retirement of the notes, provided that (i) income in respect of the notes 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. See “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders” in the accompanying product supplement for a more detailed discussion of the rules applicable to Non-U.S. Holders of the notes.

As discussed under “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders—Dividend Equivalents Under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code of 1986, as amended, 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 (“Underlying Securities”) or indices that include Underlying Securities. Section 871(m) generally applies to instruments that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations. However, the regulations, as modified by an Internal Revenue Service (“IRS”) notice, exempt financial instruments issued prior to January 1, 2025 that do not have a “delta” of one. Based on the terms of the notes and representations provided by us, our counsel is of the opinion that the notes should not be treated as transactions that have a “delta” of one within the meaning of the regulations with respect to any Underlying Security and, therefore, should not be subject to withholding tax under Section 871(m).

A determination that the notes 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 notes.

If withholding tax applies to the notes, 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 notes.

You should also consult your tax adviser regarding all aspects of the U.S. federal tax consequences of an investment in the notes 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 notes, is acting as principal and will receive an underwriting fee of $25.00 for each note sold in this offering. From this underwriting fee, CGMI will pay selected dealers not affiliated with CGMI a fixed selling concession of $25.00 for each note they sell.

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 Notes

CGMI calculated the estimated value of the notes 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 notes by estimating the value of a hypothetical package of financial instruments that would replicate the payout on the notes, which consists of a fixed-income bond (the “bond component”) and one or more derivative instruments underlying the economic terms of the notes (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 notes 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.

For a period of approximately three months following issuance of the notes, the price, if any, at which CGMI would be willing to buy the notes from investors, and the value that will be indicated for the notes 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 notes. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the three-month temporary adjustment period. However, CGMI is not obligated to buy the notes from investors at any time. See “Summary Risk Factors—The notes will not be listed on any securities exchange and you may not be able to sell them prior to maturity.”
