Theratechnologies Announces Closing of US$25 Million Public Offering of

Common Shares and Concurrent Private Placement

This news release constitutes a “designated news release” for the purposes of the Company’s prospectus supplement dated December 16, 2021 to its short form base shelf prospectus dated December 14, 2021.

Montreal, Quebec, October 31, 2023 – Theratechnologies Inc. (“Theratechnologies” or the “Company”) (Nasdaq: THTX; TSX: TH), a biopharmaceutical company focused on the development and commercialization of innovative therapies, today announced that it has closed its previously announced public offering (the “Public Offering”) of 12,500,000 common shares of the Company (the “Common Shares”) at a public offering price of US$1.00 per Common Share (the “Offering Price”). The gross proceeds of the Public Offering are US$12,500,000, before deducting the underwriting discounts and commissions and other estimated offering expenses. Pursuant to the underwriting agreement dated October 25, 2023, the Company has also granted the underwriter a 30-day option (the “Option”) to purchase up to 1,875,000 Common Shares at the Offering Price, less underwriting discounts and commissions.

Cantor Fitzgerald & Co. acted as sole bookrunner for the Public Offering.

In connection with the Public Offering, the Company has also closed its concurrent private placement with Investissement Québec (the “Concurrent Private Placement”) of 9,118,184 Common Shares and 3,381,816 fully-funded, non-voting subscription receipts, exchangeable into Common Shares on a one-for-one basis (the “Exchangeable Subscription Receipts”) in lieu of Common Shares, in each case, at the Offering Price, for US$12,500,000 aggregate gross proceeds, less a capital commitment fee of 1.5% payable to Investissement Québec and Investissement Québec’s legal fees. The component of the Concurrent Private Placement in the form of Exchangeable Subscription Receipts is designed to ensure that, following completion of the Public Offering and the Concurrent Private Placement, Investissement Québec does not have beneficial ownership or control over more than 19.9% of the issued and outstanding Common Shares and therefore is not a “control person” within applicable Canadian securities laws. All securities issued in connection with the Concurrent Private Placement are subject to a four-month hold period from the closing date under applicable Canadian securities laws, in addition to such other restrictions as may apply under applicable securities laws of jurisdictions outside Canada.

The Company also entered into an investor rights agreement, pursuant to which Investissement Québec will be entitled to nominate one director to the Company’s board of directors for as long as it holds 50% of the Common Shares purchased pursuant to the Concurrent Private Placement. Copies of the subscription agreement, the exchangeable receipt agreement setting forth the terms and conditions of the Exchangeable Subscription Receipts and the investor rights agreement, when available, will be filed on SEDAR+ at www.sedarplus.ca. Summaries of the subscription agreement and the exchangeable receipt agreement and a copy of the investor rights agreement, when available, will be filed on EDGAR at www.sec.gov.

As at the date of closing, Investissement Québec beneficially owns approximately 19.9% (25.4% if the Exchangeable Subscription Receipts were to be exchanged into Common Shares) of the issued and outstanding Common Shares. If the Option is exercised in full, Investissement Québec will beneficially own approximately 19.1% (24.5% if the Exchangeable Subscription Receipts were to be exchanged into Common Shares) of the issued and outstanding Common Shares as of the date of closing.

The Public Offering and the Concurrent Private Placement are subject to final acceptance of the Toronto Stock Exchange.

No securities regulatory authority has either approved or disapproved the contents of this news release. This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any province, state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such province, state or jurisdiction.
