Whether the securities pay a contingent coupon and, if they are not redeemed prior to maturity, whether you receive the face amount of yoursecurities at stated maturity, will depend, in each case, on the closing value of the lowest performing Underlier on the relevant calculation day. The lowest performing Underlier onany calculation day is the Underlier that has the lowest closing value on that calculation day as a percentage of its starting value■Contingent Coupon.The securities will pay a contingent coupon on a monthly basis until the earlier of stated maturity or early redemption if,and only if, the closing value of thelowest performing Underlier on the calculation day for that month is greater than or equal to its coupon threshold value. However, if the closing value of the lowest performingUnderlier on a calculation day is less than its coupon threshold value, you will not receive any contingent coupon for the relevant month. If the closing value of the lowest performingUnderlier is less than its coupon threshold value on every calculation day, you will not receive any contingent coupons throughout the entire term of the securities. The couponthreshold value for each Underlier is equal to 80% of its starting value. The contingent coupon rate will be determined on the pricing date and will be at least 11.80% per annum■Optional Redemption.Wells Fargo Finance LLC may, at its option, redeem the securities on any quarterly optional redemption date beginning approximately six months afterissuance. The optional redemption dates are the same dates as the contingent coupon payment dates following each calculation day scheduled to occur in February, May, Augustand November from February 2027 to November 2030, inclusive. If Wells Fargo Finance LLC elects to redeem the securities prior to maturity, you will receive the face amount plusa final contingent coupon payment, if otherwise payable■Potential Loss of Principal.If Wells Fargo Finance LLC does not redeem the securities prior to stated maturity, you will receive the face amount at stated maturity if,and only if,the closing value of the lowest performing Underlier on the final calculation day is greater than or equal to its downside threshold value. If the closing value of the lowest performingUnderlier on the final calculation day is less than its downside threshold value, you will receive less than the face amount and be exposed on a leveraged basis to any decline in thevalue of that Underlier in excess of the buffer amount of 20%. In this case, you will lose 1.25% of the face amount for every 1% decline in the value of the lowest performingUnderlier on the final calculation day in excess of the buffer amount. The downside threshold value for each Underlier is equal to 80% of its starting value■If the securities are not redeemed prior to stated maturity, you will have downside exposure on a leveraged basis to any decline in the value of the lowest performing Underlier onthe final calculation day in excess of the buffer amount, but you will not participate in any appreciation of any Underlier and will not receive any dividends on the securities includedin any Underlier■Your return on the securities will dependsolelyon the performance of the Underlier that is the lowest performing Underlier on each calculation day. You will not benefit in any wayfrom the performance of the better performing Underliers. Therefore, you will be adversely affected ifany Underlierperforms poorly, even if the other Underliers perform favorably■All payments on the securities are subject to credit risk, and you will have no ability to pursue any securities included in any Underlier for payment; if Wells FargoFinance LLC, asissuer, and Wells Fargo & Company, as guarantor, default on their obligations, you could lose some or all of your investment■No exchange listing; designed to be held to maturity The current estimated value of the securities is approximately $982.60 per security. While the estimated value of the securities at pricing may differ from the estimatedvalue set forth above, we do not expect it to differ significantly absent a material change in market conditions or other relevant factors. In no event will the estimatedvalue of the securities on the pricing date be less than $952.
