EDMONTON, AB, Aug. 19, 2026 /PRNewswire/ - Aurora Cannabis Inc. ("Aurora" or the "Company") (TSX: ACB) (NASDAQ: ACB), the Canadian-based leading global medical cannabis company, confirmed that Curaleaf Holdings, Inc. ("Curaleaf") (TSX: CURA) (OTCQX: CURLF), has commenced an unsolicited take-over bid for all of the issued and outstanding common shares of the Company (the "Aurora Shares") at a stated implied consideration of US$4.00 per Aurora Share, consisting of 0.3463 subordinate voting shares of Curaleaf plus US$0.75 in cash per Aurora Share (the "Offer"). We note that the Offer includes a cap on the value of the consideration of US$5.00 per Aurora Share, which is a lower price than Aurora Shares have traded as recently as December 18, 2025.

Miguel Martin, Executive Chairman and CEO of Aurora stated, "The strong shareholder support demonstrated at our 2026 AGM reinforces our commitment to the long-term strategy we are executing. We believe Curaleaf made a strategic decision to make its offer public to pressure our shareholders into making a short-term decision for the benefit of Curaleaf shareholders. We will not do that. We are building this Company for the long term and will always do what is right for Aurora shareholders."

"Contrary to assertions by Curaleaf, our door is always open to those that see value in our Company. Aurora has been in dialogue with Curaleaf going back to June 22, 2026 and as recently as August 12, 2026. Their objective is to acquire Aurora's highly strategic EU-GMP facilities and leading medical cannabis platforms at the lowest price possible, thereby depriving Aurora shareholders of any current and future value they generate," concluded Mr. Martin.

The Offer follows an announcement by Curaleaf on August 11, 2026 of its intention to make an offer for Aurora. At that time, Aurora confirmed that it received letters from Curaleaf dated June 23, 2026, and July 7, 2026, outlining proposals to acquire the Aurora Shares. The June 23, 2026, letter contained no proposed financial terms and the July 7, 2026, letter included no detail regarding the mix of cash and share consideration being proposed by Curaleaf.

The Company expects to provide a more comprehensive response to Aurora shareholders in a timely manner.
