Investment Committee and Board of Directors Recommendation

The Investment Committee of the board of directors of the Company (the “ Investment Committee ”) and the board of directors of the Company (the “ Board ”), after consulting with their financial and legal advisors and having carefully considered, among other factors, the terms of the Transaction, and after receiving an opinion from BMO Nesbitt Burns Inc. concluding that, as of February 11, 2026, based upon and subject to the assumptions, limitations and qualifications set forth in its opinion, the consideration to be paid by the Company pursuant to the Share Purchase Agreement is fair and reasonable, from a financial point of view, to the Company, has unanimously (with certain interested directors abstaining from voting) determined that the Transaction is in the best interests of the Company and that the terms and conditions of the Transaction are fair and reasonable to the Company. Accordingly, the Investment Committee and the Board have unanimously (with certain interested directors abstaining from voting) approved the Transaction and recommends that the Shareholders vote IN FAVOUR of the Transaction at the Meeting.

Reasons for the Recommendation

In making its recommendation that Shareholders vote in favour of the Transaction, the Investment Committee and the Board carefully considered a number of factors, including the factors summarized below (which are set out in full in and qualified in their entirety by reference to the Circular):

• Positions the Company as a Leader in the Global Cannabis Market . The Transaction accelerates Organigram’s expansion into global cannabis markets by establishing a leading position in Germany, the world’s second-largest federally legal cannabis market after Canada, valued at over €2 billion in 2025 and serving approximately 800,000 patients, with market forecasts projecting continued growth beyond €4.5 billion by 2028. Through exposure to Germany, the UK, Switzerland and Poland, the Company will be well positioned to capture growth in rapidly expanding European markets.
• Creates a Vertically Integrated European Hub and Sophisticated Commercial Footprint. The Transaction will provide the Company with a vertically integrated European footprint, embedding a highly skilled local leadership team and a strong network of strategic partners in the global cannabis supply chain. Entering the European supply chain with Sanity Group’s deep network will position the Company to sell significantly greater volumes of high-margin flower, creating the ability to capture more of the value chain. The Company will capitalize on Sanity Group’s sophisticated commercial capabilities across Germany, Poland, the UK, and Switzerland and engage Sanity Group’s regulatory expertise, which is critical to navigating new markets.
• Financially Accretive Acquisition with Strong Growth and Profitability Profile. The Transaction is expected to be financially accretive to the Company, delivering meaningful and strategic scale to the Company’s revenue and profitability. In 2025, Sanity Group demonstrated consistent net revenue growth from €9 million in 2023 to €60 million in 2025, including €19 million generated in the fourth quarter of 2025, with continued profitability anticipated. Sanity Group has achieved consistent gross margin improvements, from 15% in 2023 to 47% in 2025, and based on Sanity Group’s internal estimates, has grown to the second largest market share position in the German cannabis market as of November 2025.
• Establishes a European Retail Presence and Credibility for Future Pilot Projects. The Company will gain immediate access to the Swiss retail market through Sanity Group’s two established pilot project locations. Sanity Group’s pilot project experience and established branding will enhance the Company’s credibility for future pilot projects in new European markets, specifically as the global regulatory landscape continues to evolve.
• Expansion of Organigram Brand and Intellectual Property. The Transaction will provide the Company with the potential opportunity to implement its industry leading brands and intellectual property into new global markets and support the expansion of its strategic partnerships. Sanity Group’s portfolio of brands reflects shared values surrounding innovation, whereby the Company can expand its focus on new developments including a suite of emulsions, novel vapour formulations, flavour innovations, and packaging solutions. The Company anticipates the expansion and collaboration with Sanity Group’s established brands will deliver market share and revenue growth for the Company by appealing to a broad range of consumers seeking new, progressive cannabis formats.
