UBS AG has issued a Preliminary Pricing Supplement for Trigger Autocallable Contingent Yield Notes linked to the common stock of Netflix, Inc. The Notes have a trade date of June 26, 2026, expected settlement on June 30, 2026, a final valuation date of June 28, 2029 and a maturity date of July 2, 2029.

The Notes pay periodic contingent coupons only if the underlying closing level meets a coupon barrier on observation dates (quarterly after six months). They are subject to an automatic call if the underlying closes at or above the initial level on any observation date. If not called, principal repayment at maturity is contingent on the final level relative to a downside threshold; if the final level is below that threshold, investors bear downside market exposure and could lose a substantial portion or all of principal. All payments depend on UBS’s creditworthiness.

UBS AG is offering Trigger Autocallable Contingent Yield Notes linked to the common stock of Intel Corporation maturing on July 2, 2029. The offering documents describe periodic contingent coupons paid only when the underlying closing level meets or exceeds a coupon barrier, an automatic call if the underlying equals or exceeds the initial level on an observation date, and contingent repayment of principal at maturity dependent on the final level relative to a downside threshold.

Key structural points: principal amount per Note is $10; minimum investment is 100 Notes ($1,000); estimated initial value was $9.70 as of the trade date. The product exposes investors to equity downside (including the possibility of losing the entire principal if the final level is below the downside threshold) and to UBS credit risk.
