iANTHUS SECURITIES LITIGATION

PROOF OF CLAIM AND RELEASE FORM

Deadline for Submission: April 17, 2024

If you purchased or otherwise acquired defendant iAnthus Capital Holdings, Inc. (“iAnthus”) securities during the period from May 14, 2018, through July 10, 2020, inclusive (the “Settlement Class Period”), pursuant to domestic transactions, and were allegedly damaged thereby you are a “Settlement Class Member” and you may be entitled to share in the settlement proceeds. (Excluded from the Settlement Class are (i) Defendants, (ii) current and former officers and directors of iAnthus and GGP; (iii) members of the immediate family of each of the Individual Defendants; (iv) all subsidiaries and affiliates of iAnthus and GGP and the directors and officers of iAnthus, GGP, and their respective subsidiaries or affiliates; (v) all persons, firms, trusts, corporations, officers, directors, and any other individual or entity in which any Defendant has a controlling interest; (vi) the legal representatives, agents, affiliates, heirs, successors in-interest, or assigns of all such excluded parties; and (vii) any persons or entities who properly exclude themselves by filing a valid and timely request for exclusion.)

If you are a Settlement Class Member, you must complete and submit this Claim Form and Release Form (“Claim Form”) by 11:59 p.m. EST on April 17, 2024 in order to be eligible for any Settlement benefits.

Your failure to submit your claim by April 17, 2024, will subject your claim to rejection and preclude you from receiving any money in connection with the Settlement of this Action. Do not mail or deliver your claim to the Court or to any of the Parties or their counsel, as any such claim will be deemed not to have been submitted. Submit your claim only to the Claims Administrator. If you are a Settlement Class Member and do not submit a proper Claim Form, you will not share in the Settlement, but you nevertheless will be bound by the Judgment of the Court unless you exclude yourself.

Submission of a Claim Form does not ensure that you will share in the proceeds of the Settlement.
