CanniMed's intention to acquire Newstrike is highly conditional and oppressive to CanniMed shareholders in light of Aurora's proposed offer

VANCOUVER, Nov. 20, 2017 /CNW/ - Aurora Cannabis Inc. (the "Company" or "Aurora") (TSX: ACB) announced today that, further to its press release of November 14, 2017, it intends to make an offer (the "Offer") to purchase all of the issued and outstanding common shares (the "CanniMed Shares") of CanniMed Therapeutics Inc. ("CanniMed") (TSX: CMED) for consideration consisting of common shares of Aurora (the "Aurora Shares").

The Offer will provide holders of CanniMed Shares with 4.52586207 Aurora Shares for each CanniMed Share, subject to a maximum of $24.00 per CanniMed Share (the "Cap Price"). If the market value for 4.52586207 Aurora Shares is more than the Cap Price (based on the 20-day VWAP of Aurora Shares on the earlier of the expiry date for the Offer and the date on which the conditions to the Offer have been satisfied), then Aurora will adjust the number of Aurora Shares offered as consideration in the Offer, such that the consideration payable for each CanniMed Share is equal to the Cap Price.

The Offer Price, which would currently be equivalent to the Cap Price of $24.00 given Aurora's closing share price of $5.51 on November 17, 2017, represents a 56.9% premium over the closing price of CanniMed Shares on November 14, 2017, the last day prior to the public disclosure of Aurora's intention to pursue a combination with CanniMed.

Background to the Offer

On November 13, 2017, Aurora presented the CanniMed board of directors (the "Board") with a proposal (the "Proposal") to explore a mutually agreeable merger on the terms set forth in the Offer, and requested a response prior to 5:00 pm Pacific Time on November 17, 2017 (the "Proposal Deadline"). Although CanniMed's Board failed to respond to the Proposal prior to the Proposal Deadline, Aurora would still welcome a transaction supported by CanniMed's Board, and looks forward to engaging with CanniMed's Board to deliver significant value to CanniMed shareholders. However, at this time, the rationale for the combination is too strong to accept inaction, and thus the decision has been made to proceed to take Aurora's Offer directly to shareholders.

"While we have attempted to engage and have a constructive dialogue with CanniMed's Board and management about the strong merits of our offer, their refusal to enter into such a discussion, along with the powerful strategic rationale for the combination, leaves us no recourse at this point but to launch a formal offer for the company," said Terry Booth, CEO of Aurora. "We believe that CanniMed shareholders would benefit greatly from a combination, not only through the very significant premium we are offering for their shares, but also by participating in Aurora's continued growth, which is well above our industry peers, and is based on superior business strategy and exceptional, industry-leading execution. We already have the support from a large percentage of CanniMed shareholders, and look forward to bringing this process to a positive conclusion for the benefit of our combined shareholders."

CanniMed's Highly Conditional Intention to Acquire Newstrike Resources

CanniMed's announcement late on November 17, 2017 (the "CanniMed Press Release") of its highly conditional intention to acquire Newstrike Resources Ltd. ("Newstrike Resources" and "Newstrike Resources Offer") is extremely troubling in light of the bona fide acquisition proposal that Aurora presented to CanniMed's Board on November 13, 2017. At no point did CanniMed try to engage or otherwise entertain discussions with Aurora regarding the significant offer that had been presented to their Board for CanniMed shareholders prior to entering into the Newstrike Resources agreement.

The Newstrike Resources Offer requires CanniMed shareholders to approve the transaction. Given that 38% of CanniMed shareholders have contractually agreed to support the Aurora Offer and to vote against any proposed action by the CanniMed Board, the Newstrike Resources Offer is a highly conditional proposition with significant uncertainty.

In entering into the highly conditional agreement, CanniMed has agreed to pay a $9.5 million termination fee to Newstrike Resources should a superior proposal, such as the Aurora Offer, emerge. The termination fee, if paid, represents approximately $0.41 cash per share loss to CanniMed shareholders.

The assertion in the CanniMed Press Release that the terms of the Aurora offer "are unknown" is dubious, given that the detailed terms available to CanniMed shareholders were outlined in the proposal delivered by Aurora on November 13, 2017 to the CanniMed Board.

In light of these considerations, it is clear the Newstrike Resources Offer should be considered oppressive to CanniMed shareholders and to Aurora's Offer, which delivers significantly higher financial and strategic value to CanniMed shareholders. Aurora is reviewing its options with respect to CanniMed's Newstrike Resources Offer and will comment further in due course.

Reasons for CanniMed Shareholders to Support the Aurora-CanniMed Combination

High Likelihood of Completion.

Aurora has rapidly become a globally dominant cannabis company with a proven track record of exceptional shareholder value creation, with its rapid expansion driven by its agility, innovation and unparalleled execution.

The Offer provides CanniMed shareholders the opportunity to continue to participate in the compelling industry growth alongside the established and successful track record of Aurora. Increased Scale, Capital Markets Presence and Access to Capital. The pro forma combined company would have a market capitalization of approximately $3 billion , in addition to significantly enhanced liquidity relative to CanniMed, providing greater access to capital. Aurora has cash of more than $340 million upon closing of its two current capital initiatives, relative to only $54 million for CanniMed. Aurora's capital position provides very significant firepower to continue pursuing its aggressive global expansion and differentiation strategy.

Aurora has cash of more than upon closing of its two current capital initiatives, relative to only for CanniMed. Aurora's capital position provides very significant firepower to continue pursuing its aggressive global expansion and differentiation strategy. Potential for Downward Share Price Impact if Offer is Not Accepted. The Offer represents a significant premium to the market price of CanniMed shares prior to the public announcement of Aurora's interest to acquire CanniMed. Given the the agreements with the Locked-Up Shareholders, CanniMed will be unable to proceed with an alternative competing transaction to the Offer. If the Offer is not successful and no competing transaction is made, Aurora believes it is likely the trading price of CanniMed shares will decline to pre-Offer levels.

Proposed Offer Particulars

Provided Aurora does not uncover or otherwise identify information suggesting that the business, affairs, prospects or assets of CanniMed have been materially impaired, Aurora intends to commence the bid during the week of November 20, 2017 and thereafter mail a takeover bid circular to the registered holders of CanniMed Shares (in the time required under applicable Canadian securities laws).
