Organigram Closes Second Tranche of Previously Announced BAT Private Placement Investment

TORONTO, Ontario – September 3, 2024 – Organigram Holdings Inc. (NASDAQ: OGI) (TSX: OGI), (the “Company” or “Organigram”), a leading licensed producer of cannabis, announced today that on August 30, 2024, the Company closed the second of three tranches (the “Second Tranche”) of the previously announced C$124,559,674 follow-on strategic equity investment (the “Investment”) by BT DE Investments Inc. (the “Investor”), a wholly owned subsidiary of British American Tobacco plc (“BAT”). Pursuant to the Second Tranche closing, the Investor acquired 4,429,740 common shares (the “Common Shares”) and 8,463,435 Class A preferred shares (the “Preferred Shares” and together with the Common Shares, the “Shares”) of the Company at a price of C$3.2203 per share (the “Per Share Price”) for gross proceeds of USD$30,821,684.69 (equal to C$41,519,891)1. The remaining 12,893,175 Shares subscribed for are due to be issued at the Per Share Price in the final tranche on or around February 28, 2025 (the “Third Tranche”).

“With two tranches of the Jupiter pool now funded, combined with our strong balance sheet and targeted investment strategy, Organigram is well on its way to executing on its ambitious growth plan focusing on international, technological and product expansion,” said Paolo De Luca, Chief Strategy Officer of Organigram. “Our inaugural Jupiter investment in Open Book Extracts marked our second investment in the U.S. market, and our first international investment in Sanity Group represents a significant first step in our ambitions to grow our footprint in the fast-growing German market,” he concluded.

Update on the “Jupiter” Strategic Investment Pool

As previously announced, most of the Investment is being used by Organigram to fund a strategic investment pool, named “Jupiter” (the “Jupiter Pool”). The Jupiter Pool was designed to accelerate Organigram’s international growth ambitions and targets investments both overseas and in the United States, with rigorous legal compliance processes. Following the closing of the first tranche on January 23, 2024 (the “First Tranche Closing”), the Company has already made two important investments from the Jupiter Pool.

1 As determined using the average daily exchange rate published by the Bank of Canada on August 28, 2024 for converting Canadian dollars into U.S. dollars.

The first investment of USD $2 million was made in Open Book Extracts (“OBX”), a North Carolina-based company that is a leading ingredient provider, product formulator and manufacturer of hemp derived extracts and products. OBX has a scalable platform, differentiated products, formulation expertise, tremendous access to the U.S. market and a leadership position in the fast-growing hemp derivatives category.

The second investment of €14 million (~ C$21 million), was made in Sanity Group GmbH (“Sanity”), a market leader in the fast-growing German medical market. This investment marks Organigram’s first strategic investment aimed at expanding its presence in Europe. Sanity has quickly established itself as a leader in the German cannabis market where it maintains a robust distribution network with over 2,000 pharmacies working with approximately 5,000 physicians in Germany. Sanity currently holds an estimated market share position of over 10% in Germany and has experienced an over 100% run rate revenue growth from the pre-April 1st period to the date hereof. Sanity is also participating in a Swiss recreational cannabis pilot program in the Canton of Basel-Landschaft, with two stores operational and a plan to expand its retail footprint in Switzerland. Later this summer, Sanity is expected to invest in proprietary distribution channels providing it with what it believes will be a competitive advantage that capitalizes on new medical consumers entering the market.

As previously announced, the Investment is being undertaken in three (3) tranches, each subject to the satisfaction of certain conditions. Under the First Tranche Closing, 12,893,175 Common Shares were issued to the Investor at the Per Share Price. If the Third Tranche were completed on the date hereof, the Investor would beneficially own 32,571,942Common Shares and 21,356,610 Preferred Shares, which would represent 30% of the issued and outstanding Common Shares and 100% of the issued and outstanding Preferred Shares, in each case on a non-diluted basis.

The final combination of Common Shares and Preferred Shares issued on closing of the Third Tranche will be such higher / lower numbers as may be permitted by the 30% Threshold.

The Preferred Shares are non-voting convertible preferred shares of the Company convertible at the option of the Investor without payment of any additional consideration (subject to the 30% Threshold). The Preferred Shares are convertible initially on a one-for-one basis, provided however that the conversion rate will increase at a rate of 7.5% per annum commencing from the initial date on which Preferred Shares are issued, until such time as the holders of Preferred Shares would beneficially own, or exercise control or direction over, directly or indirectly, with their respective affiliates, associates, related parties

and any joint actors, after giving effect to the conversion of the Preferred Shares, 49.0% of the aggregate number of Common Shares issued and outstanding.

The Jupiter Pool is to be invested by the Company in accordance with the terms of reference provided for in the A&R Investor Rights Agreement.

The Subscription Agreement contains customary voting support covenants of the Investor in connection with the approval of matters related to the Investment by the Company’s shareholders, which approval was obtained at the Company’s annual and special meeting of shareholders held on January 18, 2024. In addition, it contains a covenant of the Company not to issue or obligate itself to issue any securities, including Shares, during the term of the Subscription Agreement, except (1) (a) with the prior written consent of the Investor, (b) as permitted under Company’s equity incentive plans, (c) as expressly contemplated by or pursuant to the Investor’s top-up and pre-emptive rights under the A&R Investor Rights Agreement, or (d) at a price that is at or above the Per Share Price, and (2) initially up to 15,756,648 Shares (based on estimated pro forma shareholdings that would result in the Investor owning at least 40% of the Shares outstanding if the First Tranche, the Second Tranche, and the Third Tranche were completed) at any price, but subject to increase as agreed to by the Company and the Investor acting reasonably, if the number of Shares outstanding increases over time.
