UBS AG offers Trigger Autocallable Contingent Yield Notes linked to the least performing of the Russell 2000^® Index, the EURO STOXX 50^® Index and shares of the State Street Utilities Select Sector SPDR ETF. The notes have a principal amount of $1,000 per Note, quarterly observation dates (callable after 12 months) and maturity expected on May 28, 2031. Payments depend on whether each underlying asset meets specified call thresholds, coupon barriers and downside thresholds; contingent coupons are paid only if every underlying asset is at/above its coupon barrier on an observation date. If not automatically called and the least performing underlying asset finishes below its downside threshold, the payment at maturity may be less than principal (you can lose a significant portion or all of your investment). The estimated initial value range is $921.50 to $951.50 per Note and net proceeds to UBS per Note are at least $958.75.

If the least performing underlying return is positive you receive the lesser of that return or the maximum upside; if zero or negative but at-or-above the downside threshold you receive a capped contingent absolute return (up to 15.00%); if below the downside threshold you suffer losses in excess of the buffer and could lose almost all principal.

The notes will be automatically called prior to maturity if the underlying closing level on an observation date is at or above the initial level, in which case holders receive principal plus any contingent coupon then due. If not called, principal repayment at maturity is contingent: if the final level is at or above the downside threshold, UBS pays the $10 principal per note; if the final level is below the downside threshold, repayment is reduced proportionally to the underlying return, potentially causing a total loss of principal. The estimated initial value as of the trade date is $9.80. Payments are subject to UBS credit risk. Trade date: April 27, 2026; settlement: April 29, 2026; final valuation date: April 27, 2028; maturity: May 1, 2028.

UBS AG (London Branch) priced capped, leveraged, buffered basket-linked notes. The notes reference an unequally-weighted basket of five indices with an initial basket level set to 100. The notes offer 200.00% upside participation subject to a cap (expected between 109.40% and 111.03%) and a buffer protecting declines up to 10.00% (buffer level = 90.00%). The maximum settlement amount is expected to be between $1,188.00 and $1,220.60 per $1,000 face amount. If the final basket level is below the buffer, investors incur leveraged downside (approximately 1.1111% loss of face amount per 1% below the buffer). The notes do not bear interest, are unsecured obligations of UBS, and the estimated initial value is expected to be between $952.00 and $982.00 per $1,000 face amount.

UBS AG London Branch is offering Digital S&P 500® Index-Linked Medium-Term Notes with a face amount of $1,000 per note and an aggregate initial offering of $1,895,000. The notes mature on June 28, 2028 and pay no interest. The cash settlement depends on the S&P 500 closing level from the trade date (April 23, 2026) to the determination date (June 26, 2028). If the final index level is ≥ the buffer level (85.00% of the initial level of 7,108.40, i.e., 6,042.14), holders receive a capped maximum settlement amount of $1,187.00 per $1,000 face amount. If the final index level is below the buffer, losses apply at approximately 1.1765% of face per 1% index decline below the buffer, possibly resulting in total loss of principal. The estimated initial value on the trade date was $997.00 per $1,000 face amount; the issue price equals face (100.00%), and the notes are unsecured obligations of UBS (credit risk applies).
