Issuer*:	Credit Suisse AG (“Credit Suisse”), acting through its London branch
Trade Date:	Expected to be October 31, 2019
Settlement Date:	Expected to be November 5, 2019
Underlyings:	The S&P 500® Index, the Russell 2000® Index and the Nasdaq-100 Index
Fixed Payment Percentage**:	Expected to be at least 13%
Redemption Amount:	At maturity, for each $1,000 principal amount of securities, $1,000 x (1 + Security Performance Factor).
Security Performance Factor:	The Security Performance Factor is expressed as a percentage and is calculated as follows: if (a) a Knock-In Event has not occurred, the Security Performance Factor will equal the Fixed Payment Percentage; or (b) a Knock-In Event has occurred, the Security Performance Factor will equal the lesser of (i) zero and (ii) the Underlying Return of the Lowest Performing Underlying.
Underlying Return:	For each Underlying: (Final Level – Initial Level)/Initial Level
Knock-In Level**:	For each Underlying, approximately 70% of the Initial Level of such Underlying.
Knock-In Event:	Occurs if, on any trading day during the Observation Period, the closing level of any Underlying is less than its Knock-In Level.
Initial Level:	For each Underlying, the closing level of such Underlying on the Trade Date.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.

Valuation Date:	January 29, 2021
Maturity Date:	February 3, 2021
CUSIP:	22551N2E5
Fees:	Certain fiduciary accounts may pay a purchase price of at least $996 per $1,000 principal amount of securities. Credit Suisse Securities (USA) LLC and any agent (the “Agents”) may receive varying discounts and commissions of up to $8 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.

Credit Suisse currently estimates the value of each $1,000 principal amount of the securities on the Trade Date will be between $970 and $1,000 (as determined by reference to our pricing models and the rate we are currently paying to borrow funds through issuance of the securities (our “internal funding rate”)). This range of estimated values reflects terms that are not yet fixed. A single estimated value reflecting final terms will be determined on the Trade Date. See “Selected Risk Considerations” in this pricing supplement.

Certain Product Risks

• Your investment may result in a loss of up to 100% of the principal amount of securities you hold. If a Knock-In Event has occurred, you will be fully exposed to any depreciation in the Lowest Performing Underlying. Regardless of the amount of any payment you receive on the securities, your actual yield may be different in real value terms.

• The value of the securities and the payment of any amount due on the securities are subject to the credit risk of Credit Suisse.

• The securities do not pay interest.

• The probability that (i) the closing level of any Underlying will be less than its Knock-In Level on any trading day during the Observation Period and (ii) the Final Level of the Lowest Performing Underlying will be less than its Initial Level will depend on the volatility of each respective Underlying.

• The appreciation potential of the securities will be limited. If a Knock-In Event has occurred, your appreciation potential is limited to the Fixed Payment Percentage, even if the level of one or more Underlyings increases from its Initial Level to its Final Level by more than the Fixed Payment Percentage.

• The Redemption Amount will be based on the Underlying Return of the Lowest Performing Underlying and, therefore, you will not benefit from the performance of the other Underlying.

• The securities are exposed to the risk of fluctuations in the level of the Underlyings to the same degree for each Underlying.

• The return on the securities is affected by the Final Level of the Lowest Performing Underlying and by whether a Knock-In Event occurs.

FINANCIAL PRODUCTS FACT SHEET

Offering Period: October 1, 2019 — October 30, 2019

Digital Barrier Notes due February 3, 2021

Linked to the Performance of the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the Nasdaq-100 Index

Additional Risk Considerations

· The Redemption Amount will be less than the principal amount of securities you hold even if a Knock-In Event has occurred with respect to only one Underlying as long as the Final Level of the Lowest Performing Underlying is less than its Initial Level. The securities are exposed equally to risk of fluctuations in the levels of the Underlyings to the same degree for each Underlying.

· The securities are linked to the Russell 2000^® Index and are subject to the risks associated with small-capitalization companies.

· Some of the assets included in the Nasdaq-100 Index are issued by foreign companies. Foreign companies may be subject to different political, market, economic, regulatory and other risks than those applicable to domestic companies, including changes in foreign governments, economic and fiscal policies, currency exchange laws or other laws or restrictions.

· Prior to maturity, costs such as concessions and hedging may affect the value of the securities.

· Credit Suisse currently estimates that the value of the securities on the Trade Date will be less than the price you pay for the securities, reflecting the deduction of underwriting discounts and commissions and other costs of creating and marketing the securities.

· If on the Trade Date the internal funding rate we use in structuring notes such as these securities is 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”), 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.

· 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.

· 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. Many factors, most of which are beyond the control of the Issuer, will influence the value of the securities and the price at which the securities may be purchased or sold in the secondary market. For example, the creditworthiness of the Issuer, including actual or anticipated downgrades to the Issuer’s credit ratings, may be a contributing factor.

· 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 of the securities, hedging our obligations under the securities and determining the estimated value of the securities. The agent for this offering, Credit Suisse Securities (USA) LLC (“CSSU”), is our affiliate. In accordance with FINRA Rule 5121, CSSU may not make sales in this offering to any discretionary accounts without the prior written approval of the customer.

· The securities will be affected by a number of economic, financial, political, regulatory and judicial factors that may either offset or magnify each other.

· As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions with respect to the equity securities comprising the Underlyings. Your return on the securities will not reflect the return you would realize if you actually owned the equity securities that comprise the Underlyings.

· The U.S. federal tax consequences of an investment in the securities are unclear.

The risks set forth in the section entitled “Certain Product Risks” on the preceding page and this section “Additional Risk Considerations” are only intended as summaries of some of the risks relating to an investment in the securities. Prior to investing in the securities, you should, in particular, review the “Certain Product Risks” and “Additional Risk Considerations” sections herein, the “Selected Risk Considerations” section in the preliminary pricing supplement and the “Risk Factors” section in the product supplement, which set forth risks related to an investment in the securities.
