Overview
As previously announced, Terrestrial Energy Inc. (“New Terrestrial Energy”) (formerly known as HCM II Acquisition Corp., or “HCM II”), a Delaware corporation (prior to the Domestication, a Cayman Islands exempted company), entered into that certain Business Combination Agreement, dated as of March 26, 2025 (as amended from time to time, the “Business Combination Agreement”), by and among HCM II, Terrestrial Energy Development Inc., a Delaware corporation (formerly known as Terrestrial Energy Inc., or “Legacy Terrestrial Energy”), and HCM II Merger Sub Inc., a Delaware corporation and a direct wholly owned subsidiary of HCM II (“Merger Sub”), pursuant to which: (1) at the closing of the transactions contemplated by the Business Combination Agreement (the “Closing”) and following the Domestication (as defined below), Merger Sub merged with and into Legacy Terrestrial Energy (the “Merger”), with Legacy Terrestrial Energy surviving as a wholly owned subsidiary of New Terrestrial Energy, resulting in a combined company whereby New Terrestrial Energy became the sole stockholder of Legacy Terrestrial Energy, as more fully described in the definitive proxy statement and final prospectus of HCM II, dated September 26, 2025 (the “Proxy Statement/Prospectus”), which was filed with the SEC; (2) HCM II domesticated (the “Domestication”) as a Delaware corporation in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), the Companies Act (As Revised) of the Cayman Islands (the “Companies Act”) and the amended and restated memorandum and articles of association of HCM II (as amended from time to time, the “Cayman Constitutional Documents”); and (3) the other transactions contemplated by the Business Combination Agreement and documents related thereto were consummated (such transactions, together with the Merger and the Domestication, the “Transactions”).
An extraordinary general meeting of HCM II shareholders was held on October 20, 2025 (the “Extraordinary General Meeting”), where the HCM II shareholders considered and approved, among other matters, a proposal to approve the Business Combination Agreement and the Transactions. In connection with the Extraordinary General Meeting, holders of 7,390 HCM II Class A Ordinary Shares (as defined below) exercised their right to redeem their shares for cash at a redemption price of $10.54 per share (the “Redemption Price”), for an aggregate redemption amount of approximately $77,890 (the “Redemption”).
On October 23, 2025, as contemplated by the Business Combination Agreement and described in the section titled “The Domestication Proposal” of the Proxy Statement/Prospectus, HCM II filed a notice of deregistration with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and filed a certificate of incorporation (the “Certificate of Incorporation”) and a certificate of corporate domestication with the Secretary of State of the State of Delaware, pursuant to which HCM II was domesticated and continued as a Delaware corporation.

Immediately prior to the Domestication, pursuant to the Cayman Constitutional Documents and the Sponsor Support Agreement dated March 26, 2025, among HCM II and Legacy Terrestrial Energy, each of the then issued and outstanding Class B ordinary shares of HCM II, par value $0.0001 per share (each, a “HCM II Class B Ordinary Share”), converted automatically, on a one-for-one basis, into one (1) Class A ordinary share of HCM II, par value $0.0001 per share (each, a “HCM II Class A Ordinary Share” and together with the HCM II Class B Ordinary Shares, the “HCM II Ordinary Shares) (the “Sponsor Share Conversion”). In connection with the Domestication: (i) each then issued and outstanding HCM II Class A Ordinary Share (that was not redeemed pursuant to the Redemption) converted automatically, on a one-for-one basis, into one (1) share of common stock, par value $0.0001 per share, of New Terrestrial Energy (each a “New Terrestrial Common Share” and collectively, the “New Terrestrial Common Shares”); (ii) each of the then issued and outstanding warrants representing the right to purchase one HCM II Class A Ordinary Share (each an “HCM II Warrant”) converted automatically into a warrant to acquire one (1) New Terrestrial Common Share (each a “New Terrestrial Warrant”); and (iii) each of the then issued and outstanding HCM II Units (as defined in the Proxy Statement/Prospectus) was cancelled and each holder thereof became entitled to one (1) New Terrestrial Common Share and one-half (1/2) of one New Terrestrial Warrant. No fractional warrants were issued upon such cancellation.
Subject to, and in accordance with the terms and conditions of the Business Combination Agreement, prior to or concurrently with the Effective Time:
| i. | each share of common stock, par value $0.001, of Legacy Terrestrial Energy (the “Terrestrial Common Shares”) that was issued and outstanding immediately prior to the Effective Time (other than the Excluded Shares (as defined below) and any Dissenting Shares (as defined in the Business Combination Agreement) was cancelled and converted into the right to receive a number of New Terrestrial Common Shares equal to the Exchange Ratio of 44.7029, which was calculated in accordance with the Business Combination Agreement (the “Per Share Base Consideration”); |
| ii. | each share of preferred stock, par value $0.001, of Legacy Terrestrial Energy designated as “Series A Preferred Stock” or “Series A-1 Preferred Stock” that was issued and outstanding immediately prior to the Effective Time (other than Excluded Shares and Dissenting Shares) was cancelled and converted into the right to receive a number New Terrestrial Common Shares equal to: (A) the number of Terrestrial Common Shares into which such Terrestrial Series A Preferred Shares were converted in accordance with Legacy Terrestrial Energy’s governing documents as of immediately prior to the Effective Time; multiplied by (B) the Per Share Base Consideration; |
| iii. | each Terrestrial Common Share and Terrestrial Series A Preferred Share that, immediately prior to the Effective Time, was owned by HCM II or Merger Sub (or any other subsidiary of HCM II), or held by Legacy Terrestrial Energy (in treasury or otherwise), if any (each, an “Excluded Share”), was automatically cancelled and retired without any conversion thereof and ceased to exist, and no consideration was delivered in exchange therefore; |
| iv. | each share of preferred stock, par value $0.001 per share, of Legacy Terrestrial Energy previously designated as “Special Voting Preferred Stock” was cancelled and converted into the right to receive one share of preferred stock, par value $0.0001 per share, of New Terrestrial Energy designated as “Special Voting Preferred Stock” pursuant to New Terrestrial Energy’s certificate of incorporation; |
| v. | each option to purchase Terrestrial Common Shares (each, a “Terrestrial Option”) that was outstanding and unexercised immediately prior to the Effective Time was automatically assumed by New Terrestrial Energy such that, as of the Effective Time, each share underlying each Terrestrial Option became New Terrestrial Common Shares and the number of such shares were equal to the Exchange Ratio, with such assumption and adjustment completed in a manner intended to satisfy the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and, with respect to any Terrestrial Option that was intended to be an “incentive stock option”, Section 422 of the Code; |
| vi. | each warrant to purchase Terrestrial Common Shares or other equity interests of Legacy Terrestrial Energy (each, a “Terrestrial Warrant”) that was outstanding and unexercised immediately prior to the Effective Time was automatically assumed by New Terrestrial Energy and became exercisable, in accordance with the terms and conditions of such Terrestrial Warrant, for the Per Share Base Consideration; |
| vii. | Each eight percent (8%) Convertible Note due 2026 issued by Legacy Terrestrial Energy (“Terrestrial Convertible Note”) that was outstanding immediately prior to the Effective Time was cancelled and automatically converted pursuant to its terms, and the holder thereof became entitled to receive, a number of New Terrestrial Common Shares equal to (A) the outstanding amount of such Terrestrial Convertible Note, including any accrued and unpaid interest, divided by (B) seventy-five percent (75%) of the Redemption Price; and |
| viii. | Each restricted stock unit (“RSU”) representing the right to receive Terrestrial Common Shares (each, a “Terrestrial RSU”) that was outstanding immediately prior to the Effective Time was automatically assumed by New Terrestrial Energy such that, as of the Effective Time, each share underlying each Terrestrial RSU became New Terrestrial Common Shares and the number of such shares were equal to the Exchange Ratio. |

Director Independence
The Board undertook a review of the independence of each director and considered whether each director of the Company has a material relationship with the Company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, the Board determined that each of Frederick Buckman, Shawn Matthews, Hugh MacDiarmid, David Hill, William Johnson, Charles Pardee and Robert W. Jones was considered an “independent director” as defined under the Nasdaq listing requirements and rules and the applicable rules of the Exchange Act.
Additional information with respect to the independence of the directors of the Company following the Closing of the Transactions is set forth in the Proxy Statement/Prospectus in the section entitled “Management of New Terrestrial Energy Following the Business Combination —Director Independence” beginning on page 316, and that information is incorporated by reference herein.

CEO Transaction Bonus
As of October 21, 2025 (the “Grant Date”), Legacy Terrestrial Energy and Mr. Irish entered into a Restricted Stock Unit Agreement (“RSU Agreement”), pursuant to which Mr. Irish was awarded 22,888 RSUs in Legacy Terrestrial Energy. The RSU Agreement was entered into to recognize the efforts of Mr. Irish in furtherance of completion of the Transactions and to incentivize Mr. Irish to remain employed beyond the Closing. Pursuant to the RSU Agreement, 50% of the RSUs will vest on the 12-month anniversary of the Grant Date, and the remaining 50% of the RSUs will vest on the 24-month anniversary of the Grant Date, subject to Mr. Irish’s continued employment through each vesting date; provided that, if Mr. Irish is terminated without “cause” or due to Mr. Irish’s death or disability (each a “Qualifying Termination”), all unvested RSUs will immediately accelerate and become vested as of the date of such Qualifying Termination. In the event that Mr. Irish is terminated as a result of an event that is not a Qualifying Termination, all unvested RSUs held by Mr. Irish pursuant to the RSU Agreement will be automatically forfeited. Vested RSUs will be settled in New Terrestrial Common Shares on or before the 10th business day following the applicable vesting date.
In the event of a “change in control” after the completion of the Transactions, the Board may unilaterally take one or more of the following actions with respect to the RSUs: (i) arrange for the surviving corporation or acquiring corporation to assume or continue the RSU Agreement or substitute a similar stock award; (ii) accelerate the vesting, in whole or in part, of the RSU Agreement; or (iii) cancel or arrange for the cancellation of the RSU Agreement.

A transaction shall not constitute a change in control if its sole purpose is to change the state of New Terrestrial Energy’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held New Terrestrial Energy’s securities immediately before such transaction.
Committees of the Board of Directors
