Credit Suisse Announces Expected Coupon Payments on Credit Suisse X-Links^® Exchange Traded Notes (the “ETNs”)

On December 1, 2023, Credit Suisse announced expected coupon payments for the following ETNs:

ETN Ticker	ETN Name	Closing Indicative Value on 11/30/23	Ex-Date	Record Date	Payment Date	Expected Coupon Amount per ETN¹	Coupon Frequency	Expected Current Yield²
USOI	Credit Suisse X-Links^® Crude Oil Shares Covered Call ETN	$73.5466	12/19/23	12/20/23	12/27/23	$0.7674	Monthly	21.60%³
GLDI	Credit Suisse X-Links^® Gold Shares Covered Call ETN	$143.2543	12/19/23	12/20/23	12/27/23	$0.5785	Monthly	6.97%³
SLVO	Credit Suisse X-Links^® Silver Shares Covered Call ETN	$77.0558	12/19/23	12/20/23	12/27/23	$0.3258	Monthly	6.78%³

1. On November 13, 2023, the Credit Suisse Nasdaq Gold FLOWS^TM 103 Index, the Credit Suisse Nasdaq Silver FLOWS^TM 106 Index and the Credit Suisse Nasdaq WTI Crude Oil FLOWS^TM 106 Index (the “Indices”) concluded the notional sale of options on GLD shares, SLV shares and USO shares, respectively, with December 2023 expiration. We expect that the notional cash distribution generated by this sale of options will be withdrawn from the Indices on December 11, 2023, subject to adjustment in the event of any market disruption events. Assuming no redemption or acceleration of GLDI, SLVO and USOI, and that the notional cash distribution is withdrawn from the Indices on December 11, 2023, we expect to declare a Coupon Amount for GLDI, SLVO and USOI, respectively, equal to the corresponding Expected Coupon Amount. The Expected Coupon Amount is subject to change upon the occurrence of a disruption event or other unforeseen circumstances.

2. For each ETN, the Expected Current Yield equals the Expected Coupon Amount annualized and divided by the Closing Indicative Value, as discussed in more detail below. The Expected Current Yield, which is based on an ETN’s Expected Coupon Amount and its two most recent coupon payments, is not indicative of future coupon payments, if any, on the ETNs. In particular, future coupon payments on an ETN may differ significantly from its Expected Current Yield, if its Closing Indicative Value fluctuates widely in a volatile market. You are not guaranteed any coupon payment or distribution under the ETNs. Coupon payments for the ETNs (if any) are variable and do not represent fixed, periodic interest payments. The Expected Coupon Amount for any ETN may vary significantly from coupon period to coupon period and may be zero. Accordingly, the Expected Current Yield will change over time, and such change may be significant. Any payment on the ETNs is subject to Credit Suisse’s ability to pay its obligations as they become due. For more information regarding any ETN's coupon payments, please refer to such ETN's pricing supplement.

3. The Expected Current Yield for the ETN equals the sum of (i) the Expected Coupon Amount, plus (ii) the amount of the ETN's two most recent coupon payments, multiplied by four (to annualize such amounts), divided by the Closing Indicative Value, and rounded to two decimal places for ease of analysis. The Expected Current Yield is subject to change upon the occurrence of a disruption event or other unforeseen circumstances.
