Theratechnologies Announces a Risk of a Temporary Supply Disruption for

EGRIFTA SV^® in Early 2025

MONTREAL, September 17, 2024 (GLOBE NEWSWIRE) – Theratechnologies Inc. (“Theratechnologies” or the “Company”) (TSX: TH) (NASDAQ: THTX), a biopharmaceutical company focused on the development and commercialization of innovative therapies, today announced a risk of a temporary supply disruption for EGRIFTA SV^® (tesamorelin for injection) in early 2025 caused by an unexpected voluntary shutdown of the Company’s contract manufacturer’s facility following an inspection by the US Food and Drug Administration (FDA), as well as the FDA review timeline to resume distribution of the product.

“We are collaborating closely with our manufacturer and other stakeholders and will continue to work with the FDA to resume production of EGRIFTA SV^®,” said Paul Lévesque President and CEO at Theratechnologies. “We remain confident that we will avoid any impact on patients in 2025.”

The Company will implement measures to carefully manage the inventory levels of EGRIFTA SV^® to meet patient demand until early January 2025, and estimates that these measures will result in a shortfall of approximately US$1.6 million in revenue from EGRIFTA SV^® for its fiscal year 2024.

“Although this situation will affect revenues in the fourth quarter of 2024, we remain on track to deliver a strong Adjusted EBITDA in the current fiscal year and will be providing more details as part of the release of our third quarter results in October,” concluded Lévesque.

Background:

Theratechnologies’ manufacturer of EGRIFTA SV^® recently implemented a three-month voluntary shutdown of its facility to address observations by the FDA Office of Compliance, following a plant inspection. The observations issued by the FDA are not related to the manufacturing process of EGRIFTA SV^®, but rather related to the manufacturing environment of the facility. The manufacturer is finalizing its remediation measures and has confirmed to the Company that it plans to resume activities by mid-October. Based on these timelines, a batch of EGRIFTA SV^® is currently scheduled to be manufactured on October 21, 2024.

In order to resume distribution of EGRIFTA SV^®, Theratechnologies was requested by the FDA to file a Prior Approval Supplement (PAS) describing the changes made by its manufacturer. The Company expects to file the PAS on or around the manufacturing date. A PAS is reviewed by the FDA within four months of receipt.

The Company will update the market on any further material developments.

EGRIFTA SV^® is distributed in the United States only.

Although the Forward-Looking Statements contained in this press release are based upon what the Company believes are reasonable assumptions in light of the information currently available, investors are cautioned against placing undue reliance on these statements since actual results may vary from the Forward-Looking Statements contained in this press release. Certain assumptions made in preparing the Forward-Looking Statements include that: (i) the FDA will be satisfied with the remediation measures implemented by the manufacturer in response to the observations issued by the FDA and the manufacturer will resume its activities by mid-October and will manufacture a new batch of EGRIFTA SV^® on October 21, 2024; (ii) no delay in the implementation of the remaining remediation measures at the manufacturer’s site will occur; (iii) the information allowing the Company to file a PAS will be available to the Company prior to October 21, 2024; (iv) the new batch of EGRIFTA SV^® to be manufactured will meet the specifications for market release; (v) the FDA will approve the PAS as filed by the Company; (vi) current market demand for EGRIFTA SV^® will remain unaffected; and (vii) the financial impact assessment made by the Company about the potential revenue shortfall from EGRIFTA SV^® is accurate.

Forward-Looking Statements assumptions are subject to a number of risks and uncertainties, many of which are beyond the Company’s control, that could cause actual results to differ materially from those that are disclosed in or implied by such Forward-Looking Statements. These risks and uncertainties include, but are not limited to: (i) the issuance of additional observations by the FDA to the manufacturer following the finalization of their review of the remediation measures implemented at the manufacturer’s site; (ii) a delay by the manufacturer in implementing the final remediation measures at the manufacturer’s site; (iii) the receipt of negative results from the implemented remediation measures; (iv) a delay in providing the information from the remediation measures to the Company; (v) a delay by the Company in filing the PAS; (vi) a decrease in demand for EGRIFTA SV^® due to the risk of shortage; (vii) the failure of the new batch of EGRIFTA SV^® to meet the specifications allowing its release to the market; and (viii) the FDA non-approval of the PAS to be filed by the Company.

The Company refers current and potential investors to the “Risk Factors” section of the Company’s Form 20-F dated February 21, 2024 available on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov under Theratechnologies’ public filings.
