Exhibit 99.1

Theratechnologies Completes 1-for-4 Reverse Stock Split

Montreal, Canada – July 31, 2023 – Theratechnologies Inc. (“Theratechnologies”, the “Company”, or “we”) (TSX: TH) (NASDAQ: THTX), a biopharmaceutical company focused on the development and commercialization of innovative therapies, today announced that it has completed the previously announced consolidation of the issued and outstanding common shares of the Company’s share capital on the basis of one (1) post- consolidation share for each four (4) pre-consolidation shares issued and outstanding (the “Consolidation”).

The Consolidation received the applicable regulatory approvals, including from the Toronto Stock Exchange (the “TSX”) and the Nasdaq Stock Market (“NASDAQ”). No shareholder approval was required for the Consolidation to come into effect. The Company’s common shares began trading on the TSX and the NASDAQ on a consolidated basis on July 31, 2023.

No fractional common share were issued in connection with the Consolidation and, in the event that a shareholder would otherwise have been entitled to receive a fractional share upon such Consolidation, the number of common shares to be received by such shareholder was rounded up (if the fraction is half a share or more) or down (if the fraction is less than half a share) to the nearest whole common share, provided that no shareholder shall hold less than a single common share as a result of the Consolidation.

Shareholders who hold their common shares electronically either in direct registered book-entry form via a direct registration system advice/statement (“DRS”) with Computershare Trust Company of Canada (“Computershare”), the Company’s transfer agent, or in “street name” through an intermediary like a bank, broker or other nominee, will not need to take any action as the Consolidation should automatically be reflected in the transfer agent’s records and on such shareholders’ next account statement. Intermediaries may have specific procedures for processing the Consolidation, including the treatment of fractional shares.

Shareholders holding paper stock certificates were sent by Computershare a letter of transmittal which will enable them to exchange their old share certificates for a DRS representing the number of new post-Consolidation common shares they hold. Until surrendered, each stock certificate representing pre-Consolidation common shares will be deemed for all purposes to represent the number of whole post-Consolidation common shares to which the shareholder is entitled as a result of the Consolidation. A copy of the letter of transmittal is available on the Company’s SEDAR profile at www.sedar.com and on EDGAR at www.sec.gov.
