UBS AG SEC Filings

UBS AG is offering Trigger Autocallable Contingent Yield Notes linked to the common stock of Boston Scientific Corporation, with a trade date of May 18, 2026, expected settlement on May 20, 2026 and expected maturity on or about May 21, 2029. The offering is subject to delivery of final Offering Documents and will not be sold where not permitted.

The Notes pay periodic contingent coupons only if observed closing levels meet a coupon barrier and may autocall early if the underlying equals or exceeds the initial level on an observation date. The Notes repay principal at maturity only if the final level is at or above a disclosed downside threshold; otherwise principal is reduced pro rata to the underlying return, potentially resulting in a full loss. Examples in the preliminary terms show a hypothetical contingent coupon rate of 8.46% per annum ($0.2115 per $10 Note) and illustrative outcomes including a payment of $3.60 per $10 Note in a stressed scenario.

UBS AG is offering Trigger Autocallable Contingent Yield Notes linked to Palantir Technologies Inc. common stock that mature on May 21, 2029.

If not called, principal is repaid at maturity only if the final level is at or above the downside threshold; otherwise repayment declines pro rata with the underlying return and you could lose a significant portion or all of your investment. Payments, including any principal repayment, are subject to UBS credit risk. The estimated initial value at trade date is $9.71 per $10 note and the notes are offered in minimum increments of 100 notes ($1,000).

The offering sets a $10 principal amount per Note, a minimum purchase of 100 Notes (a $1,000 investment) and an estimated initial value per Note between $9.34 and $9.59. If not called, principal is repaid at maturity only if the final level is at or above the downside threshold; otherwise repayment at maturity can be less than principal and may result in a total loss tied to the underlying return. All payments are subject to the creditworthiness of UBS. Terms are subject to completion and finalization in the Offering Documents.

The Notes mature on May 21, 2029 with a principal amount of $10 per Note and an estimated initial value of $9.68 as of the trade date. The Notes pay a contingent coupon on each coupon payment date only if the closing level of Snowflake on the applicable observation date is equal to or greater than the coupon barrier; otherwise no coupon is paid. The Notes will be automatically called early if Snowflake’s closing level on any observation date prior to the final valuation date is equal to or greater than the initial level, in which case holders receive principal plus any contingent coupon then due. If the Notes are not called and the final level is below the downside threshold, holders will receive at maturity a cash payment that may be less than the principal amount and could result in a loss up to the full investment. All payments are subject to the creditworthiness of UBS.

The Notes include an 85% downside threshold (a 15% buffer) on each underlying asset: if UBS does not call the Notes and the final level of the least performing underlying asset is below its downside threshold, holders incur a loss equal to the underlying shortfall in excess of the buffer. The issue price is $1,000 per Note, the estimated initial value is $990.60, and proceeds to UBS are $995.00 per Note. Payments depend on UBS creditworthiness and the Notes will not be listed on an exchange.

Payments depend on UBS’s creditworthiness. The estimated initial value per Note is $967.30 and the issue price per Note is $1,000.
