ASC Application Filed
On September 23, 2026, Aurora filed an application with the Alberta Securities Commission seeking an order requiring Curaleaf to comply with securities laws in its hostile bid.
-
Three Disclosure Deficiencies Alleged
Aurora alleges Curaleaf's Circular fails to provide pro forma financial statements, fails to hold the bid open for the minimum 105-day deposit period, and fails to publish a French-language notice in Québec.
-
Rights Plan Trigger Risk
Aurora asserts Curaleaf's failure to comply with the 105-day period means the bid does not qualify as a 'permitted bid' under Aurora's Shareholder Rights Plan, which would be triggered if Curaleaf acquires more than 20% of Aurora's shares.
-
Board Recommendation Unchanged
Aurora's Board unanimously recommends shareholders reject Curaleaf's bid by taking no action and not tendering shares, and to withdraw any shares already tendered.
Analysis · ACB · Life Sciences
Aurora has shifted from recommending rejection to actively seeking regulatory intervention. On September 23, 2026, the company filed an application with the Alberta Securities Commission alleging that Curaleaf's hostile bid Circular violates securities laws by omitting pro forma financials, failing to hold the bid open for the mandatory 105-day period, and not publishing a French-language notice. Should the ASC agree, Curaleaf would be forced to correct its Circular and restart the deposit period, delaying the bid and potentially triggering Aurora's Shareholder Rights Plan if Curaleaf crosses the 20% ownership threshold. This marks a material escalation in the takeover defense that could significantly alter the timeline and outcome of the hostile bid.
