UBS AG is offering Buffer Autocallable GEARS linked to the Russell 2000® Index with a principal amount of $10 per Security (minimum 100 Securities). The Securities feature an autocall on the observation date and a 12.00% call return if the autocall barrier is met.

If not called, final payment at maturity (expected May 15, 2029) depends on the underlying return and a 10.00% buffer: positive returns are multiplied by upside gearing (set on trade date), while sufficiently negative returns below the downside threshold can cause losses up to nearly the full principal. The estimated initial value range is $9.464–$9.764 per Security; payments remain subject to UBS credit risk.

UBS AG offers Trigger Autocallable Contingent Yield Notes linked to the common stock of United Parcel Service, Inc. due on or about May 4, 2028. Each Note has a principal amount of $1,000 and a contingent coupon rate set on the trade date in a range of 9.65% to 9.95% per annum. The trade date is April 30, 2026 with expected settlement on May 5, 2026. Quarterly observation dates determine contingent coupon payments and whether the Notes will be automatically called. The call threshold is set at 100.00% of the initial level; the coupon barrier and downside threshold are set at 60.00% of the initial level. If not called and the final level is below the downside threshold, investors will receive a share delivery amount (principal divided by the initial level), which may be worth significantly less than principal. The estimated initial value range is $943.80 to $973.80 per Note.

UBS AG offers $3,750,000 in Trigger Autocallable Contingent Yield Notes linked to the least performing of the Nikkei 225® Index and the EURO STOXX 50® Index, maturing on May 8, 2029. The Notes pay a contingent coupon at a 9.65% per annum rate if both underlyings meet coupon barriers on observation dates and are callable quarterly beginning after 12 months.

The Notes are sold at $10.00 per Note (minimum 100 Notes) with an estimated initial value of $9.731 per Note. If not automatically called, principal repayment at maturity is contingent: full principal is repaid only if both indices are at or above their 65.00% downside thresholds; otherwise repayment equals $10 times the least performing underlying return, and investors could lose a significant portion or all of their investment. All payments are subject to UBS credit risk and limited secondary-market liquidity.

UBS AG is offering Airbag Autocallable Yield Notes linked to the common stock of Eli Lilly and Company due November 4, 2026. The Notes pay a coupon each coupon date unless automatically called on a monthly observation date. If automatically called, holders receive principal plus the coupon on the corresponding coupon payment date.

If not called, repayment at maturity depends on the final level versus a downside threshold: if the final level is at or above the threshold, UBS will repay the $10 principal plus the final coupon; if below, investors face leveraged downside exposure and could lose part or all of principal. The estimated initial value was $9.85 as of the trade date. Payments are subject to the creditworthiness of UBS.

UBS AG is offering Trigger Autocallable Contingent Yield Notes linked to the common stock of Meta Platforms, Inc. The Notes pay periodic contingent coupons only if the underlying closing level at an observation date meets or exceeds a coupon barrier and include an automatic quarterly call feature beginning after six months. If autocalled, holders receive principal plus any contingent coupon due on the call settlement date. If not autocalled, principal repayment at maturity depends on the final level versus a downside threshold; if the final level is below that threshold, holders suffer a loss equal to the underlying return and could lose their entire principal. The Notes have a trade date of April 30, 2026, an expected settlement date of May 4, 2026, a final valuation date of May 2, 2028 and a maturity date of May 4, 2028. The Notes are unsecured obligations of UBS and any payments depend on UBS's creditworthiness.

UBS AG is offering Airbag Autocallable Yield Notes linked to the common stock of Eli Lilly and Company. The Notes have a principal amount of $10 per Note, a trade date of April 30, 2026, expected settlement on May 4, 2026, a final valuation date of November 2, 2026, and a maturity date of November 4, 2026. Coupons are payable monthly in arrears and an example coupon rate is 8.52% per annum (coupon installments shown as $0.071 monthly in the examples).

The Notes are subject to an automatic call on monthly observation dates beginning after three months if the closing level of the underlying stock is at or above the initial level; an automatic call triggers repayment of principal plus the coupon then due. If not called, repayment at maturity depends on the final level relative to a downside threshold: the investor may receive principal or suffer leveraged downside exposure. The product discloses a downside leverage factor such that you would lose approximately 1.1364% of principal for each 1% decline of the underlying in excess of the threshold, and in extreme cases could lose the entire investment. All payments are subject to the creditworthiness of UBS AG.

UBS AG has circulated a preliminary pricing supplement for Trigger Autocallable Contingent Yield Notes linked to the common stock of Meta Platforms, Inc. due on or about May 4, 2028. The Notes pay a periodic contingent coupon only if the underlying closing level meets the coupon barrier on observation dates; otherwise no coupon is paid. The Notes are automatically called if the underlying closing level on any quarterly observation date (beginning after 6 months) is equal to or greater than the initial level, in which case holders receive principal plus any contingent coupon due on the call settlement date. If not called, repayment at maturity depends on the final level versus a downside threshold; if the final level is below that threshold, the cash payment may be less than principal and can result in a loss equal to the underlying return. The document states an example downside threshold and coupon barrier of $75.00 (75.00% of the initial level), an illustrative contingent coupon rate of 12.61% per annum and an estimated initial value range of $9.39 to $9.64 per $10 Note. Trade date is April 30, 2026 with expected settlement May 4, 2026. Minimum investment is 100 Notes at $10 per Note. All payments are subject to the creditworthiness of UBS AG and the pricing supplement is preliminary.

UBS AG offers Trigger Autocallable Contingent Yield Notes linked to Microsoft common stock due May 4, 2027.

If not called, repayment at maturity depends on the final level relative to the downside threshold: if the final level is below that threshold the cash payment per Note may be less than the principal amount, and investors can lose a significant portion or all of their investment. All payments are subject to UBS credit risk.
