Enhanced Barrier Digital Plus Securities Based on the STOXX® Europe 600 Index Due May 26, 2023
Ove rvie w
? The securities offered by this pricing supplement are unsecured senior 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 or less
than the stated principal amount, depending on the performance of the STOXX® Europe 600 Index (the "underlying index") from
the initial index level to the final index level.
? The securities offer modified exposure to the performance of the underlying index, with (i) a minimum positive return at maturity
so long as the final index level is greater than or equal to 75.00% of the initial index level and (ii) 1-to-1 participation in any
appreciation of the underlying index in excess of the minimum positive return. In exchange, investors in the securities must be
willing to forgo any dividends that may be paid on the stocks that constitute the underlying index. In addition, investors in the
securities must be willing to accept full downside exposure to the underlying index if the underlying index depreciates by more
than 25.00%. I f t he unde rlying inde x de pre c ia t e s by m ore t ha n 2 5 .0 0 % from t he pric ing da t e t o t he va lua t ion

(2) The issue price for investors purchasing the securities in fee-based advisory accounts will be $970.00 per security, assuming
no custodial fee is charged by a selected dealer, and up to $975.00 per security, assuming the maximum custodial fee is charged
by a selected dealer. See "Supplemental Plan of Distribution" in this pricing supplement.
(3) CGMI will receive an underwriting fee of up to $30 for each $1,000 security sold in this offering. The total underwriting fees and
proceeds to issuer in the table above give effect to the actual total underwriting fee. Selected dealers affiliated with CGMI and their
financial advisors will collectively receive from CGMI a selling concession of $30 for each $1,000 security they sell. Selected
dealers not affiliated with CGMI and their financial advisors will collectively receive from CGMI a selling concession of up to $30 for
each $1,000 security they sell. In addition, CGMI will pay selected dealers not affiliated with CGMI a structuring fee of up to $6.25
for each security they sell. We may also engage other firms to provide marketing or promotional services in connection with the
distribution of the securities. CGMI will pay these service providers a fee of up to $5 per security in consideration for providing
marketing, education, structuring or referral services with respect to financial advisors or selected dealers. 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 hedging activity related to this offering, even if the value of the securities declines. See

The Securities
The Underlying Index

Your actual payment at maturity per security will depend on the actual final index level. The examples below are intended to
illustrate how your payment at maturity will depend on whether the final index level is greater than or less than the initial index
level and by how much.

Ex a m ple 1 --U pside Sc e na rio A. The hypothetical final index level is 412.21 (an approximately 5.00% increase from the initial
index level), which is gre a t e r t ha n the initial index level by le ss t ha n the fixed return of 34.00%.
https://www.sec.gov/Archives/edgar/data/200245/000095010318006557/dp91380_424b2-us1848350.htm[5/29/2018 10:59:28 AM]

Payment at maturity per security = $1,000 + the greater of (i) the fixed return amount and (ii) $1,000 × the index percent increase

= $1,000 + the greater of (i) $340.00 and (ii) $1,000 × 5.00%

= $1,000 + $340.00

= $1,340.00

Because the underlying index appreciated from the initial index level to the hypothetical final index level and the fixed return
amount is greater than the 5.00% return you would have received based on the performance of the underlying index, your total
return on the securities at maturity in this scenario would equal the fixed return of 34.00%.

Ex a m ple 2 --U pside Sc e na rio B. The hypothetical final index level is 687.02 (an approximately 75.00% increase from the
initial index level), which is gre a t e r t ha n the initial index level by m ore t ha n the fixed return of 34.00%.

Payment at maturity per security = $1,000 + the greater of (i) the fixed return amount and (ii) $1,000 × the index percent increase

= $1,000 + the greater of (i) $340.00 and (ii) $1,000 × 75.00%

May 2018
PS-3
Citigroup Global Markets Holdings Inc.
Enhanced Barrier Digital Plus Securities Based on the STOXX® Europe 600 Index Due May 26, 2023

= $1,000 + $750.00

= $1,750.00

Because the underlying index appreciated from the initial index level to the hypothetical final index level and the 75.00% return
based on the performance of the underlying index is greater than the fixed return amount, your total return on the securities at
maturity in this scenario would reflect 1-to-1 exposure to the positive performance of the underlying index.

Ex a m ple 3 --U pside Sc e na rio C. The hypothetical final index level is 372.95 (an approximately 5.00% decrease from the initial
index level), which is le ss t ha n the initial index level but gre a t e r t ha n the barrier level.

Payment at maturity per security = $1,000 + the greater of (i) the fixed return amount and (ii) $1,000 × the index percent increase

= $1,000 + the greater of (i) $340.00 and (ii) $1,000 × -5.00%

= $1,000 + $340.00

= $1,340.00

Because the underlying index did not depreciate from the initial index level to the hypothetical final index level by more than
25.00%, your payment at maturity in this scenario would be equal to the fixed return of 34.00%, even though the hypothetical final
index level is less than the initial index level.

Ex a m ple 4 --Dow nside Sc e na rio. The hypothetical final index level is 117.77 (an approximately 70.00% decrease from the
initial index level), which is le ss t ha n the barrier level.

Payment at maturity per security = $1,000 × the index performance factor

= $1,000 × 30.00%

= $300.00

Because the underlying index depreciated from the initial index level to the hypothetical final index level by more than 25.00%, your
payment at maturity in this scenario would reflect 1-to-1 exposure to the negative performance of the underlying index.

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 the
underlying index. 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-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.

?
Y ou m a y lose som e or a ll of your inve st m e nt . 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 underlying index. If the
final index level is less than the barrier level, you will lose 1% of the stated principal amount of the securities for every 1% by
which the final index level is less than the initial index level. There is no minimum payment at maturity on the securities, and
you may lose up to all of your investment.

?
T he ba rrie r fe a t ure of t he se c urit ie s e x pose s you t o pa rt ic ula r risk s. While you will receive a minimum positive
return if the underlying index does not depreciate from the initial index level to the final index level by more than 25.00%, if the
underlying index does depreciate by more than 25.00% and as a result the final index level is less than the barrier level, you
will lose 1% of the stated principal amount of the securities for every 1% depreciation of the underlying index, and you may lose
your entire investment in the securities.

?
T he se c urit ie s do not pa y int e re st . 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.

?
I nve st ing in t he se c urit ie s is not e quiva le nt t o inve st ing in t he unde rlying inde x or t he st oc k s t ha t
c onst it ut e t he unde rlying inde x . 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. As of May 23, 2018, the average dividend yield of
the underlying index was approximately 3.38% per year. While it is impossible to know the future dividend yield of the
underlying index, if this average dividend yield were to remain constant for the term of the securities, you would be forgoing an
aggregate yield of approximately 16.90% (assuming no reinvestment of dividends) by investing in the securities instead of
investing directly in the stocks that constitute the underlying index or in another investment linked to the underlying index that
provides for a pass-through of dividends. The payment scenarios described in this pricing supplement do not show any effect
of lost dividend yield over the term of the securities.

?
Y our pa ym e nt a t m a t urit y de pe nds on t he c losing le ve l of t he unde rlying inde x on a single da y. Because
your payment at maturity depends on the closing level of the underlying index solely on the valuation date, you are subject to
the risk that the closing level of the underlying index 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 underlying index that
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 levels
of the underlying index, you might have achieved better returns.

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.

https://www.sec.gov/Archives/edgar/data/200245/000095010318006557/dp91380_424b2-us1848350.htm[5/29/2018 10:59:28 AM]

?
T he se c urit ie s w ill not be list e d on a ny se c urit ie s e x c ha nge a nd you m a y not be a ble t o se ll t he m prior
t o m a t urit y. 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.

a nd our int e rna l funding ra t e , is le ss t ha n t he issue pric e . 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) the selling
concessions and 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.

?
T he e st im a t e d va lue of t he se c urit ie s w a s de t e rm ine d for us by our a ffilia t e using proprie t a ry pric ing
m ode ls. 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 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.

?
T he e st im a t e d va lue of t he se c urit ie s w ould be low e r if it w e re c a lc ula t e d ba se d on our se c onda ry
m a rk e t ra t e . 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 we will pay to investors in the securities, which do not bear interest.

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.

?
T he e st im a t e d va lue of t he se c urit ie s is not a n indic a t ion of t he pric e , if a ny, a t w hic h CGM I or a ny ot he r

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
https://www.sec.gov/Archives/edgar/data/200245/000095010318006557/dp91380_424b2-us1848350.htm[5/29/2018 10:59:28 AM]

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.

?
T he va lue of t he se c urit ie s prior t o m a t urit y w ill fluc t ua t e ba se d on m a ny unpre dic t a ble fa c t ors. The value
of your securities prior to maturity will fluctuate based on the level and volatility of the underlying index and a number of other

the value of non-U.S. stocks involve risks associated with the securities markets in those countries, including risks of volatility
in those markets, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also,
there is generally less publicly available information about companies in some of these jurisdictions than about U.S. companies
that are subject to the reporting requirements of the SEC. Further, non-U.S. companies are generally subject to accounting,
auditing and financial reporting standards and requirements and securities trading rules that are different from those applicable
to U.S. reporting companies. The prices of securities in foreign markets may be affected by political, economic, financial and
social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency
exchange laws. Moreover, the economies in such countries may differ favorably or unfavorably from the economy of the United
States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self-
sufficiency.

a high degree of fluctuation relative to the U.S. dollar. However, the performance of the underlying index and the value of your
securities will not be adjusted for exchange rate fluctuations. If the euro appreciates relative to the U.S. dollar over the term of
the securities, your return on the securities will underperform an alternative investment that offers exposure to that appreciation

such stocks over the term of the securities and may publish research or express opinions, that in each case are inconsistent

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. As described below under "United States Federal Tax Considerations," in 2007 the
U.S. Treasury Department and the IRS released a notice requesting comments on various issues regarding the U.S. federal
income tax treatment of "prepaid forward contracts" and similar instruments. Any Treasury regulations or other guidance
promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in

timing of income or loss and the degree, if any, to which income realized by non-U.S. persons should be subject to withholding
tax, possibly with retroactive effect.

In addition, Section 871(m) of the Internal Revenue Code of 1986, as amended (the "Code"), imposes a withholding tax of up
to 30% on "dividend equivalents" paid or deemed paid to non-U.S. investors in respect of certain financial instruments linked to
U.S. equities. In light of Treasury regulations, as modified by an IRS notice, that provide a general exemption for financial
instruments issued in 2018 that do not have a "delta" of one, the securities should not be subject to withholding under Section
871(m). However, the IRS could challenge this conclusion. If withholding applies to the securities, we will not be required to
pay any additional amounts with respect to amounts withheld.

You should read carefully the discussion under "United States Federal Tax Considerations" and "Risk Factors Relating to the

United States Federal Tax Considerations

You should read carefully the discussion under "United States Federal Tax Considerations" and "Risk Factors Relating to the
https://www.sec.gov/Archives/edgar/data/200245/000095010318006557/dp91380_424b2-us1848350.htm[5/29/2018 10:59:28 AM]

Securities" in the accompanying product supplement and "Summary Risk Factors" in this pricing supplement.

In the opinion of our counsel, Davis Polk & Wardwell LLP, which is based on current market conditions, 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.

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:

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

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

Subject to the discussions below under "Possible Withholding Under Section 871(m) of the Code" 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.

In 2007, the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax
treatment of "prepaid forward contracts" and similar instruments. The notice focuses in particular on whether to require holders of
these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics,
including the character of income or loss with respect to these instruments; whether short-term instruments should be subject to
any such accrual regime; the relevance of factors such as the exchange-traded status of the instruments and the nature of the
underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals)
realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the
"constructive ownership" regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary
income and impose an interest charge. While the notice requests comments on appropriate transition rules and effective dates, any
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, including the character and timing of income or loss and the degree, if any, to
which income realized by non-U.S. persons should be subject to withholding tax, possibly with retroactive effect.

Possible Wit hholding U nde r Se c t ion 8 7 1 (m ) of t he Code . 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 (a "Specified Security"). However, the regulations, as modified by an IRS notice, exempt financial instruments issued in
2018 that do not have a "delta" of one. Based on the terms of the securities and representations provided by us, 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 Specified Securities subject to withholding tax under
Section 871(m).

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. For example, if
you enter into other transactions relating to a U.S. Underlying Equity, you could be subject to withholding tax or income tax liability
under Section 871(m) even if the securities are not Specified Securities subject to Section 871(m) as a general matter. 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.
