The notes pay contingent quarterly coupons only if the underlying stock closes at or above a specified coupon barrier on observation dates, are callable after six months if the underlying meets a call threshold, and repay principal at maturity only if the final level meets or exceeds a downside threshold; otherwise holders suffer downside market exposure and may lose a significant portion or all principal. All payments depend on UBS’s creditworthiness.

UBS AG London Branch is offering $8,000,000 aggregate face amount of Digital S&P 500® Index‑Linked Medium‑Term Notes due June 23, 2027. The notes pay no interest and settle in cash at maturity based on the S&P 500® Index performance measured from the strike date April 21, 2026 to the determination date June 21, 2027.

If the final underlier level is equal to or above the buffer level of 90.00% (initial underlier level 7,064.01), holders receive the maximum settlement amount of $1,100.20 per $1,000 face amount. If the final underlier level is below the buffer level, losses apply pro rata: holders lose approximately 1.1111% of face amount for every 1.00% negative underlier return below the buffer and could lose their entire investment. The estimated initial value as of the trade date is $985.00 per $1,000 face amount; issue price is 100.00% of face amount with an underwriting discount of 1.17% and net proceeds to the issuer of 98.83%.

A buffer protects against declines up to 10.00% (buffer level = 90.00%); if the final underlier level falls below the buffer, investors incur leveraged losses (approximately 111.11% exposure beyond the buffer). The estimated initial value on the trade date is expected to be between $967.00 and $997.00 per $1,000 face amount.
