The notes have a contingent coupon of 8.10% per annum (illustrative), a maturity date of May 3, 2029, semiannual observation dates, and an automatic call if both indices meet their call thresholds on an observation date. Principal repayment at maturity is contingent on the final levels relative to 70.00% downside thresholds; if the least performing underlying is below its downside threshold, holders bear the full downside, potentially losing all principal. The estimated initial value range is between $947.20 and $977.20 per $1,000 note; issue price is $1,000.00 with underwriting compensation of $15.00 per note.

UBS AG offers Airbag Callable Contingent Yield Notes linked to the least performing of the iShares® Russell 2000 ETF (IWM), the Nasdaq-100 Index® (NDX) and the S&P 500® Index (SPX), with a principal amount of $1,000 per Note and a final maturity of January 20, 2027. The Notes pay a contingent coupon only on observation dates when the closing level of each underlying asset is at or above its coupon barrier; otherwise no coupon is paid for that period. UBS may call the Notes in whole on any observation date (other than the final valuation date), in which case holders receive principal plus any contingent coupon otherwise due on the related call settlement date. If not called, repayment at maturity is contingent: if every underlying asset’s final level is at or above its downside threshold, UBS will repay the $1,000 principal; if any underlying asset’s final level is below its downside threshold, repayment will be less than principal, and holders bear leveraged downside tied to the least performing underlying asset (approximately 1.2195% loss of principal per 1% decline beyond the 18.00% threshold). The estimated initial value range on the trade date is $963.00 to $993.00. Investing involves significant market and UBS credit risk; you may lose some or all of your investment.
