MICROSECTORS™ LAUNCHES GOLD MINERS EXCHANGE TRADED NOTES ON NYSE ARCA

NEW YORK, December 2, 2020 – REX Shares, LLC (REX) has announced another expansion of its MicroSectors™ brand to include leveraged and inverse leveraged exchange traded notes linked to the S-Network MicroSectors Gold Miners Index (symbol: MINERS). These ETNs will be issued by the Bank of Montreal, trading under the symbols GDXU and GDXD. These ETNs are expected to start trading tomorrow.

MicroSectors Gold Miners 3x Leveraged ETN (GDXU) and MicroSectors Gold Miners -3x Inverse Leveraged ETN (GDXD) will start trading tomorrow on NYSE Arca. GDXU and GDXD are listed in the U.S. and offer daily resetting +3x leverage and -3x inverse leverage linked to gold miners securities.

The S-Network MicroSectors Gold Miners Index is a market capitalization weighted index designed to track the performance of two exchange traded funds – the VanEck Vectors^® Gold Miners ETF (GDX) and the VanEck Vectors^® Junior Gold Miners ETF (GDXJ). The Index was launched on August 20, 2020.

REX, a provider of alternative investment products, continues to see large demand for hedging and trading vehicles based on certain segments of the market, such as gold mining securities.

“We are excited to partner with BMO and S-Network on the launch of the gold miners equity-focused exchange traded products with 300% and -300% daily resetting leverage,” said Scott Acheychek, President of REX.

“The underlying GDX and GDXJ ETFs represent the benchmarks for senior and junior gold mining companies,” Acheychek added. “Since our founding, MicroSectors has focused on innovating the ETP landscape with the goal of providing access to targeted investable market segments for sophisticated investors. We are pleased to build on this objective with the launch of the MINERS index.”

The ETNs are senior, unsecured obligations of the Bank of Montreal.

Investment suitability must be determined individually for each investor, and the ETNs may not be suitable for all investors. This information is not intended to provide and should not be relied upon as providing accounting, legal, regulatory or tax advice. Investors should consult with their own financial advisors as to these matters.

The ETNs are intended to be daily trading tools for sophisticated investors to manage daily trading risks as part of an overall diversified portfolio. They are designed to achieve their stated investment objectives on a daily basis. The returns on the ETNs over longer periods of time can, and most likely will, differ significantly from the return on a direct long or short investment in the index.

Bank of Montreal, the issuer of the ETNs, has filed a registration statement (including a pricing supplement, a product supplement, a prospectus supplement and a prospectus) with the Securities and Exchange Commission (the “SEC”) about each of the offerings to which this free writing prospectus relates. 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. These documents may be obtained without cost by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, Bank of Montreal, any agent or any dealer participating in these offerings will arrange to send the applicable pricing supplement, product supplement, prospectus supplement and prospectus if so requested by calling toll-free at 1-877-369-5412.
