UBS AG priced a preliminary offering of Trigger Autocallable Contingent Yield Notes linked to the common stock of Amphenol Corporation, with a term to maturity of approximately three years and an expected trade date of April 14, 2026. The Notes pay a periodic contingent coupon only if the underlying closing level on an observation date meets or exceeds a coupon barrier; otherwise no coupon is paid. The Notes will be automatically called early if the underlying closes at or above the initial level on any quarterly observation date beginning after six months; an automatic call results in payment of principal plus any contingent coupon then due. If not called and the final level is below the downside threshold, the cash payment at maturity can be less than principal and may reflect the percentage decline in the underlying, possibly causing a substantial or total loss of principal. Payments are subject to UBS credit risk. The example terms show a $10 principal per Note, a 13.91% per annum contingent coupon rate (example), and a downside threshold of $60.00 (60.00% of the initial level).
