Key Terms

Issuer:

Credit Suisse AG (“Credit Suisse”), acting through its London branch

Underlyings:

The securities are linked to the performance of the lowest performing of the Underlyings set forth in the table below. For more information on the Underlyings, see “The Underlyings” herein. Each Underlying is identified in the table below, together with its Bloomberg ticker symbol, Initial Level and expected Buffer Level (each level to be determined on the Trade Date):

Underlying	Ticker	Initial Level	Buffer Level
Russell 2000^® Index	RTY <Index>		(Approximately 90% of Initial Level)
iShares^® Russell 2000 Value ETF	IWN UP <Equity>		(Approximately 90% of Initial Level)

Redemption Amount:	At maturity, for each $1,000 principal amount of securities, you will receive a Redemption Amount in cash that will equal $1,000 multiplied by the sum of one plus the Security Performance Factor, calculated as set forth below. Any payment on the securities is subject to our ability to pay our obligations as they become due.
Security Performance Factor:	The Security Performance Factor is expressed as a percentage and is calculated as follows:

	•	If the Final Level of the Lowest Performing Underlying is equal to or greater than its Buffer Level, the Security Performance Factor will equal the Fixed Payment Percentage.
		The maximum payment on the securities, assuming a Fixed Payment Percentage of 10.90% (to be determined on the Trade Date), is expected to be $1,109 per $1,000 principal amount.
	•	If the Final Level of the Lowest Performing Underlying is less than its Buffer Level, the Security Performance Factor will equal the sum of (i) the Underlying Return of the Lowest Performing Underlying and (ii) the Buffer Amount.

	If the Final Level of the Lowest Performing Underlying is less than its Buffer Level, the Security Performance Factor will be negative and you will receive less than the principal amount of your securities at maturity. You could lose up to $900 per $1,000 principal amount.
Lowest Performing Underlying:	The Underlying with the lowest Underlying Return.
Underlying Return:	For each Underlying: Final Level – Initial Level Initial Level
	The Underlying Return for any Underlying will be negative if its Final Level is less than its Initial Level.
Fixed Payment Percentage:	Expected to be 10.90% (to be determined on the Trade Date)
Buffer Amount:	Expected to be 10% (to be determined on the Trade Date)
Initial Level:	For each Underlying, the closing level of such Underlying on the Trade Date. In the event that the closing level for any Underlying is not available on the Trade Date, the Initial Level for such Underlying will be determined on the immediately following trading day on which a closing level is available.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.
Valuation Date:	April 5, 2023, subject to postponement as set forth in any accompanying product supplement under “Description of the Securities—Postponement of calculation dates.”

Maturity Date:

April 10, 2023, subject to postponement as set forth in any accompanying product supplement under “Description of the Securities—Postponement of calculation dates.” If the Maturity Date is not a business day, the Redemption Amount will be payable on the first following business day, unless that business day falls in the next calendar month, in which case payment will be made on the first preceding business day.

Events of Default:

With respect to these securities, the first bullet of the first sentence of “Description of Debt Securities— Events of Default” in the accompanying prospectus is amended to read in its entirety as follows:

· a default in payment of the principal or any premium on any debt security of that series when due, and such default continues for 30 days;

In the event the terms of the securities described in this pricing supplement differ from, or are inconsistent with, the terms described in the underlying supplement, any product supplement, the prospectus supplement or prospectus, the terms described in this pricing supplement will control.

Our Central Index Key, or CIK, on the SEC website is 1053092. As used in this pricing supplement, “we,” “us,” or “our” refers to Credit Suisse.

This pricing supplement, together with the documents listed above, contains the terms of the securities and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, fact sheets, correspondence, trade ideas, structures for implementation, sample structures, brochures or other educational materials of ours. We may, without the consent of the registered holder of the securities and the owner of any beneficial interest in the securities, amend the securities to conform to its terms as set forth in this pricing supplement and the documents listed above, and the trustee is authorized to enter into any such amendment without any such consent. You should carefully consider, among other things, the matters set forth in “Selected Risk Considerations” in this pricing supplement and “Risk Factors” in any accompanying product supplement, “Foreign Currency Risks” in the accompanying prospectus, and any risk factors we describe in the combined Annual Report on Form 20-F of Credit Suisse Group AG and us incorporated by reference therein, and any additional risk factors we describe in future filings we make with the SEC under the Securities Exchange Act of 1934, as amended, as the securities involve risks not associated with conventional debt securities. You should consult your investment, legal, tax, accounting and other advisors before deciding to invest in the securities.

You may revoke your offer to purchase the securities at any time prior to the time at which we accept such offer on the date the securities are priced. We reserve the right to change the terms of, or reject any offer to purchase the securities prior to their issuance. In the event of any changes to the terms of the securities, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.

Hypothetical Redemption Amounts at Maturity

The table and examples below illustrate hypothetical Redemption Amounts payable at maturity on a $1,000 investment in the securities for a hypothetical range of performance of the Lowest Performing Underlying. The table and examples below assume that the Fixed Payment Percentage is 10.90%, the Buffer Level for each Underlying is 90% of the Initial Level of such Underlying and the Buffer Amount is 10%. The actual Fixed Payment Percentage, Buffer Levels and Buffer Amount will be determined on the Trade Date. The hypothetical Redemption Amounts set forth below are for illustrative purposes only. The actual Redemption Amount applicable to a purchaser of the securities will be based on the Final Level of the Lowest Performing Underlying. It is not possible to predict whether or by how much the Final Level of the Lowest Performing Underlying will be less than its Buffer Level. You should consider carefully whether the securities are suitable to your investment goals. Any payment on the securities is subject to our ability to pay our obligations as they become due. The numbers appearing in the table and examples below have been rounded for ease of analysis.

TABLE: Hypothetical Redemption Amounts

Underlying Return of the Lowest Performing Underlying	Security Performance Factor	Redemption Amount per $1,000 Principal Amount of Securities
100%	10.90%	$1,109
90%	10.90%	$1,109
80%	10.90%	$1,109
70%	10.90%	$1,109
60%	10.90%	$1,109
50%	10.90%	$1,109
40%	10.90%	$1,109
30%	10.90%	$1,109
20%	10.90%	$1,109
10%	10.90%	$1,109
5%	10.90%	$1,109
0%	10.90%	$1,109
-5%	10.90%	$1,109
-10%	10.90%	$1,109
-11%	-1%	$990
-20%	-10%	$900
-30%	-20%	$800
-40%	-30%	$700
-50%	-40%	$600
-60%	-50%	$500
-70%	-60%	$400
-80%	-70%	$300
-90%	-80%	$200
-100%	-90%	$100

The following examples illustrate how the Redemption Amount is calculated.

Example 1: The Lowest Performing Underlying increases by 70% from its Initial Level to its Final Level.

Underlying	Final Level
Underlying A	170% of Initial Level
Underlying B	180% of Initial Level

Because the Final Level of the Lowest Performing Underlying is equal to or greater than its Buffer Level, the Redemption Amount is determined as follows:

Security Performance Factor	=	Fixed Payment Percentage
	=	10.90%
Redemption Amount	=	$1,000 × (1 + Security Performance Factor)
	=	$1,000 × 1.109
	=	$1,109

Because the Final Level of the Lowest Performing Underlying is equal to or greater than its Buffer Level, the Security Performance Factor is equal to the Fixed Payment Percentage. Regardless of the appreciation of the Underlying, the Security Performance Factor will not exceed the Fixed Payment Percentage.

Example 2: The Lowest Performing Underlying decreases by 5% from its Initial Level to its Final Level.

Underlying	Final Level
Underlying A	95% of Initial Level
Underlying B	125% of Initial Level

Because the Final Level of the Lowest Performing Underlying is equal to or greater than its Buffer Level, the Redemption Amount is determined as follows:

Security Performance Factor	=	Fixed Payment Percentage
	=	10.90%
Redemption Amount	=	$1,000 × (1 + Security Performance Factor)
	=	$1,000 × 1.109
	=	$1,109

Because the Final Level of the Lowest Performing Underlying is equal to or greater than its Buffer Level, the Security Performance Factor is equal to the Fixed Payment Percentage, even if the Final Level is less than the Initial Level.

Example 3: The Lowest Performing Underlying decreases by 60% from its Initial Level to its Final Level.

Underlying	Final Level
Underlying A	40% of Initial Level
Underlying B	110% of Initial Level

Because the Final Level of the Lowest Performing Underlying is less than its Buffer Level, the Redemption Amount is determined as follows:

Security Performance Factor	=	Underlying Return of the Lowest Performing Underlying + Buffer Amount
	=	-60% + 10%
	=	-50%
Redemption Amount	=	$1,000 × (1 + Security Performance Factor)
	=	$1,000 × 0.50
	=	$500

Because the Final Level of the Lowest Performing Underlying is less than its Buffer Level, you will be exposed to any depreciation in the Lowest Performing Underlying from its Initial Level to its Final Level beyond its Buffer Level.

Selected Risk Considerations

An investment in the securities involves significant risks. This section describes material risks relating to an investment in the securities. These risks are explained in more detail in the “Risk Factors” section of any accompanying product supplement.

Risks Relating to the Securities Generally

•

YOUR INVESTMENT IN THE SECURITIES MAY RESULT IN A LOSS — If the Final Level of the Lowest Performing Underlying is less than its Buffer Level, you will lose 1% of your principal for each 1% decline from its Initial Level to its Final Level beyond its Buffer Level. You could lose up to $900 per $1,000 principal amount of securities. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

REGARDLESS OF THE AMOUNT OF ANY PAYMENT YOU RECEIVE ON THE SECURITIES, YOUR ACTUAL YIELD MAY BE DIFFERENT IN REAL VALUE TERMS — Inflation may cause the real value of any payment you receive on the securities to be less at maturity than it is at the time you invest. An investment in the securities also represents a forgone opportunity to invest in an alternative asset that generates a higher real return. You should carefully consider whether an investment that may result in a return that is lower than the return on alternative investments is appropriate for you.

•

THE SECURITIES DO NOT PAY INTEREST — We will not pay interest on the securities. You may receive less at maturity than you could have earned on ordinary interest-bearing debt securities with similar maturities, including other of our debt securities, since the Redemption Amount is based on the performance of the Lowest Performing Underlying. Because the Redemption Amount may be less than the amount originally invested in the securities, the return on the securities (the effective yield to maturity) may be negative. Even if it is positive, the return payable on each security may not be enough to compensate you for any loss in value due to inflation and other factors relating to the value of money over time.

•

THE PROBABILITY THAT THE FINAL LEVEL OF THE LOWEST PERFORMING UNDERLYING WILL BE LESS THAN ITS BUFFER LEVEL WILL DEPEND ON THE VOLATILITY OF SUCH UNDERLYING — “Volatility” refers to the frequency and magnitude of changes in the level of an Underlying. The greater the expected volatility with respect to an Underlying on the Trade Date, the higher the expectation as of the Trade Date that the Final Level of such Underlying could be less than its Buffer Level, indicating a higher expected risk of loss on the securities. The terms of the securities are set, in part, based on expectations about the volatility of the Underlyings as of the Trade Date. The volatility of any Underlying can change significantly over the term of the securities. The level of any Underlying could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Underlyings and the potential to lose a significant amount of your principal at maturity.

•

LIMITED APPRECIATION POTENTIAL — If the Final Level of the Lowest Performing Underlying is greater than its Buffer Level, for each $1,000 principal amount of securities, you will receive at maturity $1,000 multiplied by the sum of one plus the Security Performance Factor. The Security Performance Factor will not exceed the Fixed Payment Percentage, regardless of the appreciation in the level of any Underlying, which may be significant. Accordingly, the maximum Redemption Amount of the securities at maturity for each $1,000 principal amount of securities is $1,000 multiplied by the sum of one plus the Fixed Payment Percentage. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

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 financial contracts that are treated as “open transactions.” If the IRS were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities, including the

timing and character of income recognized by U.S. investors and the withholding tax consequences to non-U.S. investors, might be materially and adversely affected. Even if the treatment of the securities described herein is respected, there is a risk that a security will 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.

Risks Relating to the Underlyings

•

YOU WILL BE SUBJECT TO RISKS RELATING TO THE RELATIONSHIP BETWEEN THE UNDERLYINGS — The securities are linked to the individual performance of each Underlying. As such, the securities will perform poorly if only one of the Underlyings performs poorly. For example, if one Underlying appreciates from its Initial Level to its Final Level, but the Final Level of the Lowest Performing Underlying is less than its Buffer Level, you will be exposed to the depreciation of the Lowest Performing Underlying and you will not benefit from the performance of any other Underlying. Each additional Underlying to which the securities are linked increases the risk that the securities will perform poorly. By investing in the securities, you assume the risk that the Final Level of at least one of the Underlyings will be less than its Buffer Level, regardless of the performance of any other Underlying.

It is impossible to predict the relationship between the Underlyings. If the performances of the Underlyings exhibit no relationship to each other, it is more likely that one of the Underlyings will cause the securities to perform poorly. However, if the performances of the equity securities included in each Underlying are related such that the performances of the Underlyings are correlated, then there is less likelihood that only one Underlying will cause the securities to perform poorly. Furthermore, to the extent that each Underlying represents a different market segment or market sector, the risk of one Underlying performing poorly is greater. As a result, you are not only taking market risk on each Underlying, you are also taking a risk relating to the relationship among the Underlyings.

•

THE SECURITIES ARE LINKED TO THE UNDERLYINGS AND ARE SUBJECT TO THE RISKS ASSOCIATED WITH SMALL-CAPITALIZATION COMPANIES — The Underlyings are composed of equity securities issued by companies with relatively small market capitalization. These equity securities often have greater stock price volatility, lower trading volume and less liquidity than the equity securities of large-capitalization companies, and are more vulnerable to adverse business and economic developments than those of large-capitalization companies. In addition, small-capitalization companies are typically less established and less stable financially than large-capitalization companies. These companies may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products. Therefore, the Underlyings may be more volatile than they would be if they were composed of equity securities issued by large-capitalization companies.

•

THERE ARE RISKS ASSOCIATED WITH THE iSHARES^® RUSSELL 2000 VALUE ETF — Although shares of the iShares^® Russell 2000 Value ETF (the “Reference Fund”) are listed for trading on a national securities exchange and a number of similar products have been traded on various national securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of the Reference Fund or that there will be liquidity in the trading market. The Reference Fund is subject to management risk, which is the risk that the Reference Fund’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Pursuant to the Reference Fund’s investment strategy or otherwise, its investment advisor may add, delete or substitute the assets held by the Reference Fund. Any of these actions could adversely affect the price of the shares of the Reference Fund and consequently the value of the securities. For additional information on the Reference Fund, see “The Underlyings—The iShares^® Russell 2000 Value ETF” herein.

•

THE PERFORMANCE AND MARKET VALUE OF THE REFERENCE FUND, PARTICULARLY DURING PERIODS OF MARKET VOLATILITY, MAY NOT CORRELATE TO THE PERFORMANCE

OF THE TRACKED INDEX — The Reference Fund will generally invest in all of the equity securities included in the index tracked by the Reference Fund (the “Tracked Index”) but may not fully replicate the Tracked Index. There may be instances where the Reference Fund’s investment advisor may choose to overweight a stock in the Tracked Index, purchase securities not included in the Tracked Index that such investment advisor believes are appropriate to substitute for a security included in the Tracked Index or utilize various combinations of other available investment techniques. In addition, the performance of the Reference Fund will reflect additional transaction costs and fees that are not included in the calculation of the Tracked Index. Finally, because the shares of the Reference Fund are traded on a national securities exchange and are subject to market supply and investor demand, the market value of one share of the Reference Fund may differ from the net asset value per share of the Reference Fund.

During periods of market volatility, securities held by the Reference Fund may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of the Reference Fund and the liquidity of the Reference Fund may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in the Reference Fund. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the Reference Fund. As a result, under these circumstances, the market value of shares of the Reference Fund may vary substantially from the net asset value per share of the Reference Fund. For these reasons, the performance of the Reference Fund may not correlate with the performance of the Tracked Index. For additional information on the Reference Fund, see “The Underlyings—The iShares^® Russell 2000 Value ETF” herein.

•

THE INVESTMENT STRATEGY REPRESENTED BY THE REFERENCE FUND MAY NOT BE SUCCESSFUL — The iShares^® Russell 2000 Value ETF seeks to track the investment results of its Tracked Index. The Tracked Index is designed to measure the full performance of companies included in the Russell 2000^® Index that exhibit relatively strong value characteristics and relatively weak growth characteristics and a portion of the performance of companies with more balanced value and growth characteristics. A “value” investment strategy is premised on the goal of investing in stocks that are determined to be relatively cheap or “undervalued” under the assumption that the value of those stocks will increase over time as the market comes to reflect the “fair” market value of those stocks. However, the value characteristics referenced by the Reference Fund may not be accurate predictors of undervalued stocks, and there is no guarantee that undervalued stocks will appreciate. In addition, the Reference Fund’s selection methodology includes a bias against stocks with strong growth characteristics, and stocks with strong growth characteristics might outperform stocks with weak growth characteristics. It is possible that the stock selection methodology of the Reference Fund will adversely affect its return and, consequently, the value of your securities.

•

NO OWNERSHIP RIGHTS RELATING TO THE UNDERLYINGS — Your return on the securities will not reflect the return you would realize if you actually owned shares of the Reference Fund or the assets that comprise the Underlyings. The return on your investment is not the same as the total return based on the purchase of shares of the Reference Fund or the assets that comprise the Underlyings.

•

NO VOTING RIGHTS OR DIVIDEND PAYMENTS — As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to shares of the Reference Fund or the assets that comprise the Underlyings.

•

ANTI-DILUTION PROTECTION IS LIMITED — The calculation agent will make anti-dilution adjustments for certain events affecting the Reference Fund. However, an adjustment will not be required in response to all events that could affect the Reference Fund. If an event occurs that does not require the calculation agent to make an adjustment, or if an adjustment is made but such adjustment does not fully reflect the economics of such event, the value of the securities may be materially and adversely affected. See “Description of the Securities—Adjustments” in the relevant product supplement.

•

GOVERNMENT REGULATORY ACTION, INCLUDING LEGISLATIVE ACTS AND EXECUTIVE ORDERS, COULD RESULT IN MATERIAL CHANGES TO THE UNDERLYINGS AND COULD

NEGATIVELY AFFECT YOUR RETURN ON THE SECURITIES — Government regulatory action, including legislative acts and executive orders, could materially affect the Underlyings. For example, in response to recent executive orders, stocks of companies that are determined to be linked to the People’s Republic of China military, intelligence and security apparatus may be delisted from a U.S. exchange, removed as a component in indices or exchange traded funds, or transactions in, or holdings of, securities with exposure to such stocks may otherwise become prohibited under U.S. law. If government regulatory action results in such consequences, there may be a material and negative effect on the securities.

Risks Relating to the Issuer

•

THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE — Investors are dependent on our ability to pay all amounts due on the securities and, therefore, if we were to default on our obligations, you may not receive any amounts owed to you under the securities. In addition, any decline in our credit ratings, any adverse changes in the market’s view of our creditworthiness or any increase in our credit spreads is likely to adversely affect the value of the securities prior to maturity.

•

CREDIT SUISSE IS SUBJECT TO SWISS REGULATION — As a Swiss bank, Credit Suisse is subject to regulation by governmental agencies, supervisory authorities and self-regulatory organizations in Switzerland. Such regulation is increasingly more extensive and complex and subjects Credit Suisse to risks. For example, pursuant to Swiss banking laws, the Swiss Financial Market Supervisory Authority (FINMA) may open resolution proceedings if there are justified concerns that Credit Suisse is over-indebted, has serious liquidity problems or no longer fulfills capital adequacy requirements. FINMA has broad powers and discretion in the case of resolution proceedings, which include the power to convert debt instruments and other liabilities of Credit Suisse into equity and/or cancel such liabilities in whole or in part. If one or more of these measures were imposed, such measures may adversely affect the terms and market value of the securities and/or the ability of Credit Suisse to make payments thereunder and you may not receive any amounts owed to you under the securities.

Risks Relating to Conflicts of Interest

•

HEDGING AND TRADING ACTIVITY — We or any of our affiliates may carry out hedging activities related to the securities, including in the Reference Fund or instruments related to the Underlyings. We or our affiliates may also trade in the Reference Fund or instruments related to the Underlyings from time to time. Any of these hedging or trading activities on or prior to the Trade Date and during the term of the securities could adversely affect our payment to you at maturity.

•

POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and as agent of the issuer for the offering of the securities, hedging our obligations under the securities and determining their estimated value. In performing these duties, the economic interests of us and our affiliates are potentially adverse to your interests as an investor in the securities. Further, hedging activities may adversely affect any payment on or the value of the securities. Any profit in connection with such hedging activities will be in addition to any other compensation that we and our affiliates receive for the sale of the securities, which creates an additional incentive to sell the securities to you.

Risks Relating to the Estimated Value and Secondary Market Prices of the Securities

•

UNPREDICTABLE ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE SECURITIES — The payout on the securities can be replicated using a combination of the components described in “The estimated value of the securities on the Trade Date may be less than the Price to Public.” Therefore, in addition to the levels of any Underlying, the terms of the securities at issuance and the value of the securities prior to maturity may be influenced by factors that impact the value of fixed income securities and options in general, such as:

the expected and actual volatility of the Underlyings;

the expected and actual correlation, if any, between the Underlyings;

the time to maturity of the securities;

the dividend rate on the equity securities included in the Underlyings;

interest and yield rates in the market generally;

investors’ expectations with respect to the rate of inflation;

geopolitical conditions and economic, financial, political, regulatory, judicial or other events that affect the components included in the Underlyings or markets generally and which may affect the levels of the Underlyings; and

our creditworthiness, including actual or anticipated downgrades in our credit ratings.

Some or all of these factors may influence the price that you will receive if you choose to sell your securities prior to maturity. The impact of any of the factors set forth above may enhance or offset some or all of any change resulting from another factor or factors.

•

THE ESTIMATED VALUE OF THE SECURITIES ON THE TRADE DATE MAY BE LESS THAN THE PRICE TO PUBLIC — The initial estimated value of your securities on the Trade Date (as determined by reference to our pricing models and our internal funding rate) may be significantly less than the original Price to Public. The Price to Public of the securities includes any discounts or commissions as well as transaction costs such as expenses incurred to create, document and market the securities and the cost of hedging our risks as issuer of the securities through one or more of our affiliates (which includes a projected profit). These costs will be effectively borne by you as an investor in the securities. These amounts will be retained by Credit Suisse or our affiliates in connection with our structuring and offering of the securities (except to the extent discounts or commissions are reallowed to other broker-dealers or any costs are paid to third parties).

On the Trade Date, we value the components of the securities in accordance with our pricing models. These include a fixed income component valued using our internal funding rate, and individual option components valued using proprietary pricing models dependent on inputs such as volatility, correlation, dividend rates, interest rates and other factors, including assumptions about future market events and/or environments. These inputs may be market-observable or may be based on assumptions made by us in our discretionary judgment. As such, the payout on the securities can be replicated using a combination of these components and the value of these components, as determined by us using our pricing models, will impact the terms of the securities at issuance. Our option valuation models are proprietary. Our pricing models take into account factors such as interest rates, volatility and time to maturity of the securities, and they rely in part on certain assumptions about future events, which may prove to be incorrect.

Because Credit Suisse’s pricing models may differ from other issuers’ valuation models, and because funding rates taken into account by other issuers may vary materially from the rates used by Credit Suisse (even among issuers with similar creditworthiness), our estimated value at any time may not be comparable to estimated values of similar securities of other issuers.

•

EFFECT OF INTEREST RATE USED IN STRUCTURING THE SECURITIES — The internal funding rate we use in structuring notes such as these securities is typically lower than the interest rate that is reflected in the yield on our conventional debt securities of similar maturity in the secondary market (our “secondary market credit spreads”). If on the Trade Date our internal funding rate is lower than our secondary market credit spreads, we expect that the economic terms of the securities will generally be less favorable to you than they would have been if our secondary market credit spread had been used in structuring the securities. We will also use our internal funding rate to determine the price of the securities if we post a bid to repurchase your securities in secondary market transactions. See “—Secondary Market Prices” below.

•

SECONDARY MARKET PRICES — If Credit Suisse (or an affiliate) bids for your securities in secondary market transactions, which we are not obligated to do, the secondary market price (and

the value used for account statements or otherwise) may be higher or lower than the Price to Public and the estimated value of the securities on the Trade Date. The estimated value of the securities on the cover of this pricing supplement does not represent a minimum price at which we would be willing to buy the securities in the secondary market (if any exists) at any time. The secondary market price of your securities at any time cannot be predicted and will reflect the then-current estimated value determined by reference to our pricing models, the related inputs and other factors, including our internal funding rate, customary bid and ask spreads and other transaction costs, changes in market conditions and deterioration or improvement in our creditworthiness. In circumstances where our internal funding rate is higher than our secondary market credit spreads, our secondary market bid for your securities could be less favorable than what other dealers might bid because, assuming all else equal, we use the higher internal funding rate to price the securities and other dealers might use the lower secondary market credit spread to price them. Furthermore, assuming no change in market conditions from the Trade Date, the secondary market price of your securities will be lower than the Price to Public because it will not include any discounts or commissions and hedging and other transaction costs. If you sell your securities to a dealer in a secondary market transaction, the dealer may impose an additional discount or commission, and as a result the price you receive on your securities may be lower than the price at which we may repurchase the securities from such dealer.

We (or an affiliate) may initially post a bid to repurchase the securities from you at a price that will exceed the then-current estimated value of the securities. That higher price reflects our projected profit and costs, which may include discounts and commissions that were included in the Price to Public, and that higher price may also be initially used for account statements or otherwise. We (or our affiliate) may offer to pay this higher price, for your benefit, but the amount of any excess over the then-current estimated value will be temporary and is expected to decline over a period of approximately three months.

The securities are not designed to be short-term trading instruments and any sale prior to maturity could result in a substantial loss to you. You should be willing and able to hold your securities to maturity.

•

LACK OF LIQUIDITY — The securities will not be listed on any securities exchange. Credit Suisse (or its affiliates) intends to offer to purchase the securities in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities when you wish to do so. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which Credit Suisse (or its affiliates) is willing to buy the securities. If you have to sell your securities prior to maturity, you may not be able to do so or you may have to sell them at a substantial loss.

Supplemental Use of Proceeds and Hedging

We intend to use the proceeds of this offering for our general corporate purposes, which may include the refinancing of existing debt outside Switzerland. Some or all of the proceeds we receive from the sale of the securities may be used in connection with hedging our obligations under the securities through one or more of our affiliates. Such hedging or trading activities on or prior to the Trade Date and during the term of the securities (including on any calculation date, as defined in any accompanying product supplement) could adversely affect the value of the Underlyings and, as a result, could decrease the amount you may receive on the securities at maturity. For additional information, see “Supplemental Use of Proceeds and Hedging” in any accompanying product supplement.

United States Federal Tax Considerations

This discussion supplements and, to the extent inconsistent therewith, supersedes the discussion in the accompanying product supplement under “United States Federal Tax Considerations.”

There are no statutory, judicial or administrative authorities that address the U.S. federal income tax treatment of the securities or instruments that are similar to the securities. In the opinion of our counsel, Davis Polk & Wardwell LLP, a security should be treated as a prepaid financial contract that is an “open transaction” for U.S. federal income tax purposes. However, there is uncertainty regarding this treatment. 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 Trade 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:

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

Upon a sale or other disposition (including retirement) of a security, 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 Internal Revenue Code of 1986, as amended (the “Code”), such gain or loss 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 described herein is respected, there is a risk that your purchase of a security will 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 Financial Contracts that are Open Transactions—Possible Application of Section 1260 of the Code” in the accompanying product supplement for additional information and consult your tax advisor 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, and the IRS or a court might not agree with the treatment described herein. In particular, the IRS could treat the securities as contingent payment debt instruments, in which case the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized, could be materially and adversely affected. Moreover, 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. In addition, 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 advisor regarding possible alternative tax treatments of the securities and potential changes in applicable law.

Non-U.S. Holders. Subject to the discussions in the next paragraph and in “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders” and “United States Federal Tax Considerations—FATCA” 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—Dividend Equivalents under Section 871(m) of the Code” in the accompanying product supplement, Section

871(m) of the Code generally imposes a 30% withholding tax on “dividend equivalents” paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. Treasury regulations under Section 871(m), as modified by an IRS notice, exclude from their scope financial instruments issued prior to January 1, 2023 that do not have a “delta” of one with respect to any U.S. equity. 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. 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 Trade Date for the securities and it is possible that the securities will be subject to withholding tax under Section 871(m) based on circumstances on 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 determination. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances, including your other transactions. You should consult your tax advisor 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 advisor 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 (Conflicts of Interest)

Under the terms and subject to the conditions contained in a distribution agreement dated May 7, 2007, as amended, which we refer to as the distribution agreement, we have agreed to sell the securities to CSSU. We may also agree to sell the securities to other agents that are parties to the distribution agreement. We refer to CSSU and other such agents as the “Agents.”

The distribution agreement provides that the Agents are obligated to purchase all of the securities if any are purchased.

The Agents may offer the securities at the offering price set forth on the cover page of this pricing supplement and may receive varying discounts and commissions of up to $2.50 per $1,000 principal amount of securities. The Agents may re-allow some or all of the discount on the principal amount per security on sales of such securities by other brokers or dealers. CSSU or another broker or dealer will forgo some or all discounts and commissions with respect to the sales of securities into certain fiduciary accounts. If all of the securities are not sold at the initial offering price, the Agents may change the public offering price and other selling terms.

An affiliate of Credit Suisse has paid or may pay in the future a fixed amount to broker-dealers in connection with the costs of implementing systems to support these securities.

We expect to deliver the securities against payment for the securities on the Settlement Date indicated herein, which may be a date that is greater than two business days following the Trade Date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, if the Settlement Date is more than two business days after the Trade Date, purchasers who wish to transact in the securities more than two business days prior to the Settlement Date will be required to specify alternative settlement arrangements to prevent a failed settlement.

CSSU is our affiliate. In accordance with FINRA Rule 5121, CSSU may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer. A portion of the net proceeds from the sale of the securities will be used by CSSU or one of its affiliates in connection with hedging our obligations under the securities.

For further information, please refer to “Underwriting (Conflicts of Interest)” in any accompanying product supplement.
