UBS AG is offering Trigger Autocallable Yield Notes linked to the common stock of Qualcomm (QCOM). Each Note has a $1,000 principal amount and pays a quarterly coupon; the indicated coupon rate is 10.65% per annum. The Notes are callable quarterly beginning after approximately 12 months; the first potential call settlement date is June 2, 2027. If a call condition is met on an observation date, UBS will repay principal plus the coupon on the corresponding coupon payment date. If not called and the final level at maturity is below the downside threshold (set at 50.00% of the initial level), principal repayment will be reduced pro rata to the underlying return; in extreme cases investors could lose all principal. Maturity is on or about May 31, 2030. The issue price per Note is $1,000; the estimated initial value range on the trade date is stated as $930.50 to $960.50. Payments remain subject to UBS’s creditworthiness.

UBS AG is offering Trigger Callable Contingent Yield Notes due May 24, 2029 linked to the least performing of the S&P 500®, Russell 2000® and EURO STOXX 50® indices. Each Note pays a contingent coupon of 12.50% per annum only if every underlying asset meets its coupon barrier on an observation date. UBS may call the Notes early in whole on any observation date; if not called, repayment at maturity depends on whether each index is at or above its 70.00% downside threshold. If any final level is below its downside threshold, the cash payment at maturity will decline in proportion to the worst‑performing index and could result in the loss of a significant portion or all of principal. The issue price totals $555,000 (or $1,000 per Note); proceeds to UBS are $995.00 per Note. The estimated initial value per Note as of the trade date is $991.30. Investing involves significant market, issuer credit and liquidity risks; secondary market trading may be limited and payments depend on UBS' creditworthiness.

UBS AG London Branch is offering Capped Leveraged Buffered Basket-Linked Medium-Term Notes linked to an unequally-weighted basket of five indices. The notes mature on July 9, 2027 with a trade date of May 19, 2026 and do not bear interest.

Issue price is 100.00% of face amount; estimated initial value is $986.20 per $1,000. The notes are unsecured obligations of UBS and subject to UBS credit risk.

The Notes are offered at $10 per Note (minimum 100 Notes), have an estimated initial value of $9.90, and are unsecured obligations of UBS, so all payments depend on UBS’ creditworthiness.
