BMO and REX Shares Launch MicroSectors™ 3× Long and -3× Short Semiconductor ETNs (Cboe BZX: SMHU, SMHD)

Filed Pursuant to Rule 433
Registration Statement No. 333-285508
August 3, 2026

NEW YORK, Aug. 3, 2026 /PRNewswire/ -- Bank of Montreal ("BMO") and REX Shares, LLC ("REX") announced today the launch of the following Exchange Traded Notes("ETNs") issued by BMO:

The ETNs will start trading tomorrow on the Cboe BZX Exchange, Inc. under the applicable ticker symbol identified above. The Daily Investor Fee for the ETNs has been waived until, and including, January 31, 2027. Thereafter, the Daily Investor Fee will be based on a rate of 0.70% per annum. See the applicable pricing supplement for more information regarding the fees and charges applicable to the ETNs.

Each series of ETNs is intended to offer sophisticated investors three times leveraged long or short, as applicable, participation in the daily performance of the VettaFi Semiconductor Fund-Tracking Index (the "Index"), before taking into account fees, charges and the decay effect caused by the daily resetting of the leverage.

The Index is a total return index created, sponsored and maintained by VettaFi LLC that tracks the performance of the VanEck^® Semiconductor ETF and is designed to provide exposure to the largest and most liquid U.S. exchange-listed companies in the semiconductor industry through a single fund-tracking vehicle. The ticker symbol of the Index is "SEMIS."

Disclosures

The ETNs are not intended to be "buy and hold" investments and are not intended to be held to maturity. Instead, the ETNs are intended to be daily trading tools for sophisticated investors to manage daily trading risks as part of an overall diversified portfolio. The ETNs are designed to reflect a 3× leveraged long or short, as applicable, exposure to the performance of the Index on a daily basis, before taking into account the negative effect of the fees and charges. However, as a result of the daily resetting leverage, the returns on the ETNs over different periods of time can, and most likely will, differ significantly from three times the return on a direct long or short investment in the Index. The ETNs are designed to achieve their stated investment objectives on a daily basis. The performance of the ETNs over different periods of time can differ significantly from their stated daily objectives. The ETNs are considerably riskier than securities that have intermediate- or long-term investment objectives and are not suitable for investors who plan to hold them for a period of more than one day or who have a "buy and hold" strategy. Investors should actively and continuously monitor their investments in the ETNs on an intraday basis, and any decision to hold the ETNs for more than one day should be made with great care and only as the result of a series of daily (or more frequent) investment decisions to remain invested in the ETNs for the next one-day period. The ETNs are very sensitive to changes in the level of the Index, and returns on the ETNs may be negatively affected in complex ways by the volatility of the Index on a daily or intraday basis. It is possible that investors will suffer significant losses in the ETNs that provide leveraged long exposure even if the long-term performance of the Index is positive. Similarly, it is possible that investors will suffer significant losses in the ETNs that provide short leveraged exposure even if the long-term performance of the Index is negative. Accordingly, the ETNs should be purchased only by sophisticated investors who understand and can bear the potential risks and consequences of the ETNs that are designed to provide leveraged exposure to the long or short, as applicable, performance of the Index on a daily basis and that will be highly volatile and may experience significant losses, up to the entire amount invested, in a short period of time.

For additional information, including a discussion of the risks relating to an investment in the ETNs, please carefully read the applicable pricing supplement and related documents that we have filed with respect to the ETNs (each, an "ETN Prospectus"). Investors should review the relevant ETN Prospectus carefully prior to making an investment decision.

The ETN Prospectus relating to each series of ETNs can be found on EDGAR, the Securities and Exchange Commission (the "SEC") website at: www.sec.gov, as well as on the product websites at the following links: www.bmoetns.com and www.microsectors.com.

Bank of Montreal, the issuer of each series of ETNs, has filed a registration statement (including a pricing supplement, prospectus supplement and prospectus) with the SEC regarding each series of the ETNs. Please read those documents and the other documents relating to these offerings that Bank of Montreal has filed with the SEC for more complete information about Bank of Montreal and these offerings.
