UBS AG is offering Airbag Autocallable Yield Notes linked to the common stock of Palantir Technologies Inc. due on or about April 22, 2027.

If not called, principal repayment at maturity is contingent: if the final level is at or above a downside threshold, UBS will repay the $10 principal; if below that threshold, holders bear leveraged downside (approximately 1.6667% principal loss for each 1% underlying decline beyond the threshold), and could lose their entire investment.
