The offering lists a trade date of March 30, 2026, settlement on April 1, 2026, final valuation on March 30, 2028, and maturity on April 3, 2028.

If an observation date (quarterly, beginning after six months) shows each underlying asset at or above its call threshold (100% of initial level), UBS will automatically call the Notes early and pay principal plus accrued coupon. If not called, principal is contingent at maturity: if all final levels are at or above their conversion levels (66.75% of initial), UBS pays $1,000; otherwise holders receive the share delivery amount of the least performing underlying asset, which may be worth less than principal, resulting in partial or total loss. Payments depend on UBS creditworthiness. The estimated initial value on the trade date was $959.20.

The Notes can be automatically called on quarterly call observation dates beginning after approximately six months; if called, holders receive principal plus any contingent coupon then due.

The Notes have a $10 principal per Note, trade date March 27, 2026, expected settlement March 31, 2026, final valuation date March 28, 2029 and maturity April 2, 2029. The issuer will pay periodic contingent coupons only if the underlying closing level on an observation date is at or above the coupon barrier; otherwise no coupon is paid for that period. The Notes will be automatically called early if the underlying closing level on any observation date prior to the final valuation date is equal to or greater than the initial level; in that event UBS will pay principal plus any contingent coupon due on the related coupon payment date and no further payments will be owed.

If not called, principal repayment at maturity is contingent: if the final level is at or above the downside threshold the principal is paid in cash; if the final level is below the downside threshold the cash payment may be less than principal and will equal $10 x (1 + underlying return), exposing investors to the negative return of the underlying and potential loss of all invested principal. The pricing example shows a contingent coupon rate of 12.07% per annum, a coupon per period of $0.3018, and a downside threshold and coupon barrier of $60.00 (60.00% of the initial level). The estimated initial value as of the trade date is $9.70. Any payment on the Notes is subject to the creditworthiness of UBS.

UBS AG offers Trigger Autocallable Contingent Yield Notes linked to Microsoft common stock due March 31, 2027.
