Aurora Cannabis Inc. (the "Company" or "Aurora") (NYSE: ACB) (TSX: ACB), the Canadian company defining the future of cannabinoids worldwide, has filed a prospectus supplement establishing a new at-the-market equity program (the "ATM Program") that allows the Company to issue and sell up to U.S.$300 million of common shares in the capital of the Company (the "Common Shares") from treasury to the public, from time to time, at the Company's discretion. Any Common Share sales under the ATM Program will be made through "at-the-market distributions" as defined in National Instrument 44-102 and sold through the NASDAQ Global Select Market (the "NASDAQ") or other marketplace in the United States at the prevailing market price at the time of sale. Sales may also be made in privately negotiated transactions. No sales will be made through a stock exchange or stock market in Canada.

Aurora believes this filing will provide maximum flexibility for the Company to pursue select acquisitions going forward, including within the U.S. Aurora confirms that its current cash position remains strong at approximately $525 million as of May 13, 2021. Given the strength of Aurora's current cash position, it is not expected to need to access the ATM Program without an accretive use of proceeds.

Distributions of the Common Shares through the ATM Program will be made pursuant to the terms of a sales agreement dated May 19, 2021 among the Company and a syndicate of agents led by Citigroup Global Markets Inc. and Cowen and Company, LLC and including BMO Capital Markets Corp., ATB Capital Markets USA Inc. and Canaccord Genuity LLC.
