UBS AG is offering Trigger Autocallable Contingent Yield Notes linked to the common stock of Apollo Global Management, Inc. The Notes pay a contingent coupon on coupon dates only if the underlying stock's closing level on an observation date is equal to or above a coupon barrier. The Notes may be automatically called early if the underlying closes at or above the initial level on any observation date prior to maturity.

The Notes are unsecured obligations of UBS and any payments are subject to UBS's creditworthiness.

Key dates: Trade Date: June 3, 2026, Settlement Date: June 5, 2026, Final Valuation Date: June 1, 2028, Maturity Date: June 5, 2028. The estimated initial value was $9.74 per Note and the offering minimum is 100 Notes at $10 per Note.

UBS AG is offering Trigger Autocallable Contingent Yield Notes with Memory Interest linked to the least performing of The Home Depot and McDonald’s. The Notes have a principal amount of $1,000 per Note, a contingent coupon rate of 11.00% per annum (contingent coupon $27.50), quarterly observation dates (callable after 12 months), an expected trade date of June 12, 2026, a final valuation date of June 12, 2029 and a maturity date of June 15, 2029. The Notes pay contingent coupons only if both underlying assets meet coupon barriers on observation dates, are automatically called if both underlying assets meet call thresholds on an observation date, and at maturity repay principal only if both underlyings are at or above the downside thresholds; otherwise repayment tracks the negative return of the least performing underlying asset and could result in substantial loss or total loss. Estimated initial value is stated between $956.10 and $986.10 per Note; issue price is $1,000 per Note.

UBS AG offers $475,000 of Trigger Autocallable Yield Notes linked to the common stock of Zscaler, Inc. The Notes pay a fixed coupon of $16.65% per annum in monthly installments, are approximately two‑year notes maturing on June 6, 2028, and may be automatically called monthly beginning after 12 months if the underlying stock meets the call threshold.

If not called, principal is contingent at maturity: full principal is returned only if the final level is at or above the downside threshold of $77.86 (50.00% of the initial level). If the final level is below that threshold, repayment equals $1,000×(1+Underlying Return), producing a loss equal to the percentage decline in the underlying stock. All payments are subject to UBS credit risk and potential adjustments by the calculation agent.

The issue price per Note is $1,000.00, estimated initial value is between $954.70 and $984.70, and per-Note underwriting compensation is up to $11.25, leaving proceeds of at least $988.75 per Note.
