iAnthus Announces Filing of Amended and Restated Preliminary Short Form Prospectus

NEW YORK, NY and TORONTO, ON--(Marketwired - October 26, 2017) - iAnthus Capital Holdings, Inc., (CSE: IAN) (CSE: IAN.CN) (CNSX: IAN) (OTCQB: ITHUF) ("iAnthus" or the "Company"), today announced that it has filed an amended and restated preliminary short form prospectus with the securities regulatory authorities in all provinces of Canada, except Québec, amending the terms of the proposed offering announced October 18, 2017. The amended and restated preliminary short form prospectus has been filed in respect of a proposed "best efforts" public offering of common shares of the Company at an issue price (the "Offering Price") of $1.70 per common share (the "Offering").

The Company will file a further amendment to the preliminary short form prospectus, and an associated news release, when the size of the Offering is determined.

The Offering will be made through a syndicate of agents led by Canaccord Genuity Corp. and including Beacon Securities Limited, Cormark Securities Inc., Echelon Wealth Partners Inc., and Haywood Securities Inc. (collectively, the "Agents"). The Company has granted the Agents an option, exercisable for a period of 30 days following the closing of the Offering, to arrange for the sale of up to an additional 15% of the common shares sold under the Offering for market stabilization purposes.

In addition to the Offering, the Company expects to enter into subscription agreements, on or prior to the closing date for the Offering, pursuant to which certain subscribers resident in the United States and certain international jurisdictions will agree to purchase common shares of the Company, on a non-brokered private placement basis, pursuant to exemptions from the prospectus requirements under applicable securities laws (the "Concurrent Private Placement"). The Concurrent Private Placement will be priced at the Offering Price and the common shares issued under the Concurrent Private Placement will be subject to a Canadian hold period of four months and a day from the date of issuance. The Agents are not involved, directly or indirectly, in the issuance, offer and sale of the common shares being distributed under the Concurrent Private Placement.

The Offering and the Concurrent Private Placement are subject to customary closing conditions, including regulatory approvals. The Company is proposing to use the net proceeds of the Offering and the Concurrent Private Placement for acquisition financing, other capital projects and general corporate purposes.

A copy of the amended and restated preliminary prospectus is available under the Company's SEDAR profile at www.sedar.com. There will not be any sale or any acceptance of an offer to buy the securities until a receipt for the final prospectus in respect of the Offering has been issued.

The securities being offered have not been, nor will they be, registered under the United States Securities Act of 1933, as amended, and may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons absent registration or an applicable exemption from the registration requirements. This news release will not constitute an offer to sell or the solicitation of an offer to buy nor will there be any sale of the securities in any State in which such offer, solicitation or sale would be unlawful.
