Boris Jordan's Curaleaf Just Went Hostile on Aurora Cannabis at $4.00 a Share

The founder of the biggest US cannabis company just tried to buy a rival over its board’s head

On August 24, 2026, Curaleaf Holdings ($CURLF) filed an 8-K attaching a press release that does something companies rarely do in public: it publicly argues that a rival’s management has destroyed shareholder value and asks that rival’s own shareholders to sell to Curaleaf anyway. The target is Aurora Cannabis ($ACB), and the offer is US$4.00 per share, a 45% premium.

This is the escalation of an unsolicited take-over bid that Boris Jordan, Curaleaf’s founder, Executive Chairman and CEO, launched on August 18. Jordan had already sent Aurora a formal letter of intent on June 23 and a follow-up on July 7. After Aurora declined to engage, Curaleaf took the offer straight to Aurora’s shareholders. The August 24 filing is Curaleaf’s rebuttal to Aurora’s attempt to wave the whole thing off.

What the filing actually says

Curaleaf’s offer breaks down to 0.3463 of a Curaleaf subordinate voting share plus US$0.75 in cash for each Aurora share. That is a 45% premium to Aurora’s unaffected price, or a 110% premium once you strip out Aurora’s balance sheet cash. The bid carries no financing and no due diligence conditions and stays open until December 1, 2026.

The numbers Curaleaf leans on are pointed. Over the year through August 10, Aurora’s stock fell roughly 35% while Curaleaf’s rose roughly 56%. Curaleaf also flags Aurora’s lowered fiscal 2027 guidance, which points to lower revenue and adjusted gross margins sliding from 64% toward the mid-to-high 50% range, with lower Adjusted EBITDA.

Is a 45% premium generous, or is it a lowball?

Here is the real question, and it is worth sitting with. A 45% premium sounds like a gift. But Curaleaf’s own argument is that Aurora ran itself into the ground, and a premium is measured against a price that already collapsed. Pay 45% over a number that fell 35% in a year and you are still buying near the bottom. That is exactly why the ex-cash premium is 110%: a big slice of Aurora’s remaining value is simply the cash on its books, not the operating business.

So it cuts both ways. Aurora holders get a real, immediate premium and equity in a larger, growing platform. Aurora’s board can credibly argue that stock swapped at a beaten-down price locks in the loss instead of giving management time to recover. Both things are true at once, and the tender fight is a referendum on which one shareholders believe.

The detail the headlines skipped

Most coverage stops at “45% premium, hostile bid.” The filing goes further. Curaleaf’s analysis points out that Aurora’s June quarter Adjusted EBITDA came in about 63% lower than its March quarter, that operations ran a negative C$4.4 million cash flow, and that Aurora’s cultivation yields of 114 grams per plant trail Curaleaf’s. Curaleaf also argues Aurora’s fiscal 2027 guidance describes a business shrinking back toward fiscal 2025 revenue levels.

Whether you find that persuasive or self-serving, it is the substance of the fight, and it lives in the filing rather than the press summary.

The pattern worth watching

This is a governance story before it is a cannabis story. When a bidder files an 8-K to litigate a target’s track record in public, the contest is already past the friendly stage, and the next filings (Aurora’s formal circular, any tender-support agreements, any competing bid) are where the outcome gets decided.

NexusAlert caught both moves as they happened. The Company Dossier for $CURLF shows two high-severity governance signals this week: the August 18 bid launch with the exact 45% and 110% premium math, and the August 24 rebuttal. Seeing the fight assemble filing by filing, in real time, is the point.

The lesson is the one that applies to every contested deal: read the whole filing, not the headline. The premium is the headline. The 110% ex-cash math, the C$4.4 million cash burn, and the guidance walk-back are the story.
