ITEM 5 - FULL DESCRIPTION OF MATERIAL CHANGE

On July 2, 2025, the Company announced that it had entered into a binding arrangement agreement with the Purchaser, an affiliate of Future Pak, a privately held contract manufacturer, packager and distributor of pharmaceutical and nutraceutical products, whereby the Purchaser will acquire all the issued and outstanding common shares of the Company for US$3.01 per share in cash plus one CVR per share for additional aggregate cash payments of up to US$1.19 per CVR if certain milestones as described below are achieved.

The arrangement agreement is the result of the sale process previously announced by the Company that was led by a special committee of independent directors of the Company (the “Special Committee”).

Theratechnologies’ Board of Directors, having received the unanimous recommendation of the Special Committee, has unanimously determined that the Transaction is in the best interests of the Company and is fair to its shareholders (other than those shareholders whose votes are required to be excluded for the purposes of “minority approval” under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”)), and unanimously recommends that the Company’s shareholders approve the Transaction.

Each of Barclays Capital Inc., as exclusive financial advisor to the Company and the Special Committee, and Raymond James Ltd., retained to provide independent financial advisory services to the Special Committee, has provided a fairness opinion to the Board of Directors and the Special Committee to the effect that, as at July 2, 2025, and based upon and subject to the assumptions, limitations and qualifications stated therein, the consideration to be received by shareholders pursuant to the Transaction is fair, from a financial point of view, to the shareholders of the Company.

Pursuant to the Transaction, the Purchaser will acquire all the issued and outstanding common shares of the Company for US$3.01 per share in cash plus one CVR per share, which will entitle the holder thereof to additional aggregate cash payments of up to US$1.19 per CVR, if the following Company milestones are achieved, subject to a maximum aggregate payment of US$65 million to all holders of CVRs:

 

•

for the 12-month period ending on each of the 12-, 24- and 36- month anniversaries of the closing of the Transaction, if the EGRIFTA franchise gross profit for such 12-month period surpasses US$40 million, 50% of the profits surpassing such figure will be distributed pro rata to CVR holders within 45 days of the end of each such 12-month period;

 

•

if the cumulative EGRIFTA franchise gross profit during the 36-month period following the closing of the Transaction exceeds US$150 million, a one-time payment of US$10 million will be distributed pro rata to CVR holders within 30 business days of the achievement of such milestone; and

 

•

if the cumulative gross profit from the EGRIFTA and Trogarzo franchises during the 36-month period following the closing of the Transaction exceeds US$250 million, a one-time payment of US$15 million will be distributed pro rata to CVR holders within 30 business days of the achievement of such milestone.

In each of the above instances, should the relevant milestones not be met, then no additional consideration will be payable to the holders of CVRs in relation to such milestone.

The holders of exchangeable subscription receipts (“Subscription Receipts”) and deferred share units (“DSUs”) will receive the cash consideration per share plus one CVR for each Subscription Receipt or DSU held. The holders of “in the money” options to acquire common shares (“Options”) and share appreciation rights (“SARs”) will receive an amount by which the cash consideration exceeds the exercise price of the Options or SARs, plus one CVR for each Option or SAR held. Each “out of the money” Option and SAR outstanding with an exercise price greater than the cash consideration will be entitled to a portion of the value of a CVR, which portion shall be equal to the amount by which the cash consideration plus the value of such whole CVR exceeds the exercise price of such Option or SAR. Holders of warrants to purchase common shares (“Warrants”) will receive the amount by which the cash consideration exceeds the exercise price of the Warrants, multiplied by one quarter, plus one CVR for every four warrants held.

Each CVR will be a direct obligation of the Purchaser. The CVRs will not be listed on any market or exchange, and may not be sold, assigned, transferred, pledged or encumbered in any manner, other than in limited circumstances to be described in the CVR agreement to be entered into at closing of the Transaction, a form of which is included in the arrangement agreement. The CVRs will not represent any equity or ownership interest in the Company, the Purchaser, Future Pak or any affiliate thereof (or any other person) and will not be represented by any certificates or other instruments. The CVRs will not have any voting or dividend rights, and no interest will accrue on any amounts payable on the CVRs to any holder thereof.

The Transaction will be implemented by way of a plan of arrangement under the Business Corporations Act (Québec) and is expected to close during the Company’s fourth quarter ending November 30, 2025, subject to customary closing conditions, including the receipt of required shareholder approval and the approval of the Superior Court of Québec.

The Transaction will be funded by Future Pak through a combination of debt financing and cash on hand. Future Pak has received a debt commitment letter from its lenders for a US$220 million credit facility. The debt financing is subject to limited conditions.

Required shareholder approval for the Transaction will consist of (i) at least 66²⁄₃% of the votes cast on the Transaction by holders of common shares at a special meeting of shareholders of the Company, and (ii) at least a majority of the votes cast on the Transaction by holders of common shares, excluding shares held by shareholders required to be excluded pursuant to MI 61-101, at such meeting.

Concurrently with the execution of the arrangement agreement, the Purchaser has entered into voting support agreements with members of senior management and all of the directors of the Company, together holding shares representing approximately 1.14% of the issued and outstanding common shares of the Company, pursuant to which they have agreed to vote all shares held by them in favour of the Transaction, subject to customary exceptions.

The arrangement agreement contains non-solicitation covenants on the part of the Company, subject to customary “fiduciary out” and “right to match” provisions. A termination fee of US$6 million would be payable by the Company to the Purchaser in certain circumstances, including in the context of a superior proposal supported by the Company. The Company would also be entitled to a reverse termination fee of US$12 million payable by the Purchaser to the Company if the Transaction is not completed in certain circumstances.

Following completion of the Transaction, the Company will become a privately held company, will apply to cease to be a reporting issuer under Canadian securities laws and will deregister its shares with the U.S. Securities and Exchange Commission. The common shares will no longer be publicly traded on the Toronto Stock Exchange and on the Nasdaq Capital Market.

Additional information regarding the Transaction will be included in an information circular that the Company will prepare, file and mail to its shareholders in advance of the special meeting to be held to consider and approve the Transaction. Copies of the arrangement agreement and the information circular will be available under the Company’s profile on SEDAR+ on www.sedarplus.ca and on EDGAR as an exhibit to the Schedule 13E-3 Transaction Statement to be filed by the Company at www.sec.gov.
