Corporate Governance

Change TypeDescriptionEffective DateImpact Assessment
Corporate StructureHCM II Acquisition Corp. domesticated from a Cayman Islands exempted company to a Delaware corporation, now named Terrestrial Energy Inc.2025-10-23Aligns the company with U.S. corporate governance standards and legal framework, potentially simplifying regulatory compliance and investor relations for a U.S.-listed entity.
Governing DocumentsAdoption of a new Certificate of Incorporation and Bylaws for the Delaware corporation, replacing the Cayman Constitutional Documents.2025-10-23Establishes the foundational legal framework for the new corporate entity, defining shareholder rights, board powers, and operational procedures under Delaware law.
Board StructureThe Board of Directors is divided into three classes (Class I, Class II, and Class III) with staggered terms, where each director serves for a term ending on the date of the third annual meeting following their election.2025-10-23This classified board structure can enhance board stability and continuity but may also make it more challenging for shareholders to effect immediate changes in board composition.
Director RemovalDirectors may be removed from office only for cause and only by the affirmative vote of at least 66 2/3% in voting power of all then-outstanding shares entitled to vote.2025-10-23This supermajority requirement for director removal provides significant protection for incumbent directors, potentially limiting shareholder influence over board composition.
Shareholder MeetingsAny action required or permitted to be taken by stockholders must be effected at a duly called annual or special meeting and cannot be effected by written consent in lieu of a meeting. Special meetings can only be called by the Chief Executive Officer, President, Board of Directors, Chairperson of the Board, or other Board designees, not by stockholders.2025-10-23These provisions restrict shareholder ability to act by written consent and to call special meetings, centralizing control with management and the Board.
Charter/Bylaw AmendmentsAmendment, alteration, repeal, or rescission of certain provisions of the Certificate of Incorporation and Bylaws requires the affirmative vote of at least 66% in voting power of all then-outstanding shares entitled to vote.2025-10-23Supermajority voting requirements for key governance changes make it more difficult for a simple majority of shareholders to alter fundamental corporate rules.
Forum SelectionThe Court of Chancery of the State of Delaware is designated as the sole and exclusive forum for certain internal corporate claims, and federal district courts of the United States are the exclusive forum for claims arising under the Securities Act of 1933.2025-10-23Centralizes litigation in specific, experienced courts, potentially reducing legal costs and increasing predictability for corporate disputes, but may limit plaintiffs' choice of venue.
Director and Officer LiabilityDirectors and officers are not personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty to the fullest extent permitted by Delaware law.2025-10-23Provides broad protection for directors and officers, potentially encouraging qualified individuals to serve but limiting avenues for shareholder recourse in certain circumstances.
IndemnificationThe Corporation is authorized to provide indemnification and advancement of expenses to directors, officers, and agents to the fullest extent permitted by Delaware law.2025-10-23Offers financial protection to directors and officers against legal costs and liabilities, which is standard practice and helps attract and retain talent.
