Bank of Montreal is offering US$1,440,000 in Senior Medium-Term Notes, Series K: autocallable, step-down, barrier notes linked to the MerQube US Tech+ Vol Advantage Index (MQUSTVA), priced May 8, 2026 with settlement May 13, 2026 and maturity May 13, 2031. The notes pay scheduled automatic redemption amounts on specified Observation Dates if the Reference Asset closes at or above the Call Level; if not called, maturity pay depends on the Final Level versus a Trigger Level of 8,848.76 (60.00% of the Initial Level). The cover lists a public offering price of 100%, an agent’s commission of 5.00% ($72,000), proceeds to the issuer of 95.00% ($1,368,000), and an estimated initial value of $878.70 per $1,000.

The structure exposes investors to index rules (weekly leverage resets, a 6.0% per annum daily deduction, and a notional financing cost tied to SOFR plus 0.5%). If a Trigger Event occurs at maturity, final payment equals $1,000 plus the Percentage Change, which can be less than principal.
