If the final index level is ≥90.00% of the initial level (initial level 7,398.93), holders receive a capped $1,178.50 per note. If the final index level is below 90.00%, the payment formula reduces principal (potentially to zero).

The supplement describes structure, Payment at Maturity mechanics, risk factors, calculation agent roles, adjustment rules, and distribution mechanics.

MITTS pay no periodic interest, are typically issued in $10 units, provide a Redemption Amount at maturity based on the Market Measure’s change from a Starting Value to an Ending Value (with a Participation Rate generally ≥100%), may include a Capped Value, and may pay a Minimum Redemption Amount that can be less than the principal.

The notes pay semi-annual fixed Interest Payments of at least $31.25 per $1,000 principal (3.125% per period; equivalent to at least 6.250% per annum), have an expected Trade Date of May 28, 2026, an expected Original Issue Date of June 2, 2026, and an expected Maturity Date of May 31, 2030.

The notes are automatically callable on semi-annual observation dates if the Index closes at or above the Initial Level; if not called, repayment at maturity depends on the Final Level relative to a Buffer Level set at 80% of the Initial Level. If the Final Level is below the Buffer Level, losses are amplified by a Downside Leverage Factor of 125% (equivalent to losing 1.25 of principal for each 1.00 drop beyond the 20% buffer). The price to public is $1,000 per note; the Bank's initial estimated value is between $975.20 and $995.20 per $1,000 principal.

The maximum settlement is expected between $1,253.96 and $1,298.76 per $1,000 note.
