Theratechnologies Inc. is a biopharmaceutical company focused on the development and commercialization of innovative therapies addressing unmet medical needs.

The interim consolidated financial statements include the accounts of Theratechnologies Inc. and its wholly owned subsidiaries (together referred to as the “Company” and individually as the “subsidiaries of the Company”).

Theratechnologies Inc. is governed by the Business Corporations Act (Québec) and is domiciled in Québec, Canada. The Company is located at 2015 Peel Street, Suite 1100, Montréal, Québec, H3A 1T8.

These unaudited interim consolidated financial statements (“interim financial statements”), including comparative information, have been prepared using accounting policies consistent with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and in accordance with International Accounting Standard (“IAS”) 34, Interim Financial Reporting.

Certain information, in particular the accompanying notes normally included in the annual consolidated financial statements prepared in accordance with IFRS, has been omitted or condensed. These interim financial statements do not include all disclosures required under IFRS and, accordingly, should be read in conjunction with the annual consolidated financial statements for the year ended November 30, 2020 and the notes thereto.

These interim financial statements have been authorized for issue by the Company’s Audit Committee on April 13, 2021.

The Company’s interim financial statements have been prepared on going concern and historical cost bases, except for bonds and money market funds, derivative financial assets, liabilities related to cash-settled share-based arrangements and derivative financial liabilities, which are measured at fair value. Effective December 1, 2019, lease liabilities are measured at the present value of lease payments not paid at commencement date. Equity-classified shared-based payment arrangements are measured at fair value at grant date pursuant to IFRS 2, Share-based Payment.

The methods used to measure fair value are discussed further in Note 12.

The preparation of the Company’s interim financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim financial statements, and the reported amounts of revenues and expenses during the reporting periods.

Information about critical judgments in applying accounting policies and assumptions and estimation uncertainties that have the most significant effect on the amounts recognized in the interim financial statements are disclosed in Note 1 of the annual consolidated financial statements as at November 30, 2020.

The Company’s functional currency is the United States dollar (“USD”).

All financial information presented in USD has been rounded to the nearest thousand.

The significant accounting policies as disclosed in the Company’s annual consolidated financial statements for the year ended November 30, 2020 have been applied consistently in the preparation of these interim financial statements.

On January 19, 2021, the Company completed a public offering for the sale and issuance of 16,727,900 units at a price of $2.75 per unit for a gross cash consideration of $46,002, including the full exercise of the over-allotment option.

Each Unit is comprised of one common share of the Company and one-half of one common share purchase warrant of the Company (each whole warrant, a “Warrant”). As at February 28, 2021, no Warrants were exercised and there were 8,363,950 Warrants outstanding. Each Warrant entitles the holder thereof to purchase one common share at an exercise price of US$3.18 at any time until January 19, 2024.

The Company has established a stock option plan (the “Plan”) under which it can grant its directors, officers, employees, researchers and consultants non-transferable options for the purchase of common shares. The exercise date of an option may not be later than 10 years after the grant date. A maximum number of 7,700,000 options can be granted under the Plan. Generally, the options vest at the grant date or over a period of up to three years. As at February 28, 2021, 3,679,302 options could still be granted by the Company (2020 – 1,060,717) under the Plan.

All options are to be settled by the physical delivery of common shares.

During the three-month period ended February 28, 2021, $557 (2020 – $364) was recorded as share-based compensation expense for the Plan. The fair value of options granted during the period was estimated at the grant date using the Black-Scholes model and the following weighted average assumptions:

The risk-free interest rate is based on the implied yield on a Canadian government or U.S. zero-coupon issue, with a remaining term equal to the expected term of the option. The volatility is based on weighted average historical volatility adjusted for a period equal to the expected life. The life of the options is estimated taking into consideration the vesting period at the grant date, the life of the option and the average length of time similar grants have remained outstanding in the past. The dividend yield was excluded from the calculation, since it is the present policy of the Company to retain all earnings to finance operations and future growth.

The following table summarizes the measurement date weighted average fair value of stock options granted during the period ended:

The Black-Scholes model used by the Company to calculate option values was developed to estimate the fair value of freely tradable, fully transferable options without vesting restrictions, which significantly differ from the Company’s stock option awards. This model also requires four highly subjective assumptions, including future stock price volatility and average option life, which greatly affect the calculated values.

On October 4, 2018, the Company’s Board of Directors approved a SARs plan for its consultants that entitles the grantee to a cash payment based on the increase in the stock price of the Company’s common shares from the grant date to the settlement date. The exercise date of an SAR may not be later than 10 years after the grant date. Generally, the SARs vest over a period of three years.

During the three-month period ended February 28, 2021, $21 (2020 – $1) was recorded as share-based compensation expense for the SARs plan. Since these awards will be cash-settled, the fair value of SARs granted is estimated at each reporting period using the Black-Scholes model and the following weighted average assumptions. No SARs were granted during the three-month period ended February 28, 2021.

The risk-free interest rate is based on the implied yield on a Canadian government zero-coupon issue, with a remaining term equal to the expected term of the SAR. The volatility is based on weighted average historical volatility adjusted for a period equal to the expected life. The life of the SARs is estimated taking into consideration the vesting period at the grant date, the life of the SARs and the average length of time similar grants have remained outstanding in the past. The dividend yield was excluded from the calculation, since it is the present policy of the Company to retain all earnings to finance operations and future growth.

The calculation of basic loss per share was based on the net loss attributable to common shareholders of the Company of $5,922 (2020 – $4,544) and a weighted average number of common shares outstanding of 84,692,788 (2020 – 76,953,411), calculated as follows:

For the three-month period ended February 28, 2021, 4,206,617 (2020 – 2,987,918) share options, 8,363,950 Warrants and 3,872,053 common shares potentially issuable from the conversion of the $57,500 aggregate principal amount of notes, that may potentially dilute loss per share in the future, were excluded from the weighted average number of diluted common shares calculation as their effect would have been anti-dilutive.

The Company entered into the following transactions which had no impact on its cash flows:

The nature and extent of the Company’s exposure to risks arising from financial instruments are consistent with the disclosure in the annual consolidated financial statements as at November 30, 2020.

Certain of the Company’s accounting policies and disclosures require the determination of fair value, for both financial and non-financial assets and liabilities. Fair values have been determined for measurement and/or disclosure purposes based on the following methods. When applicable, further information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability.

Financial assets and financial liabilities measured at fair value

In establishing fair value, the Company uses a fair value hierarchy based on levels as defined below:

Other financial assets and financial liabilities

The Company has determined that the carrying values of its short-term financial assets and financial liabilities, including cash, trade and other receivables and accounts payable and accrued liabilities, approximate their fair value because of their relatively short period to maturity.

Bonds and money market funds and derivative financial assets and liabilities are stated at fair value, determined by inputs that are primarily based on broker quotes at the reporting date (Level 2).

The fair value of the convertible unsecured senior notes, including the equity portion, as at February 28, 2021, was approximately $51,175 (Level 1) based on market quotes.

Three-month periods ended February 28, 2021 and February 29, 2020

(Unaudited)

Share-based payment transactions

The fair value of the employee stock options are measured based on the Black-Scholes valuation model. Measurement inputs include share price on measurement date, exercise price of the instrument, expected volatility (based on weighted average historical volatility adjusted a period equal to the expected life, weighted average expected life of the instruments (based on historical experience and general option holder behaviour), expected dividends, and the risk-free interest rate (based on government bonds). Service and non-market performance conditions attached to the transactions, if any, are not taken into account in determining fair value.

The deferred stock units liability is recognized at fair value and considered Level 2 in the fair value hierarchy for financial instruments. The fair value is determined using the quoted price of the common shares of the Company.

The Company has a single operating segment. Over 90% of the Company’s revenues are generated from one customer, RxCrossroads, which is domiciled in the United States.

All of the Company’s non-current assets are located in Canada and Ireland, as is the Company’s head office. Of the Company’s non-current assets of $33,221, $31,924 as at February 28, 2021 are located in Canada and $1,297 are located in Ireland.

Milestone oncology

In March 2021, the Company issued 481,928 common shares under the terms of the acquisition agreement entered into with all of the shareholders of Katana Biopharma Inc. (“Katana”) for Katana’s in-licensed oncology platform. The purchase price for the oncology platform provided for share-based consideration to be issued upon attainment of two milestones. The first milestone consisted in initiating a Phase 1 clinical trial evaluating TH1902 for the treatment of sortilin positive solid tumors. This milestone was achieved in March 2021. The estimated fair value of the share-based consideration of $614, initially recorded in contributed surplus on the date of the acquisition, will be reclassified to share capital in the second quarter.

available, investors are cautioned against placing undue reliance on these statements since actual results may vary from the Forward-Looking Statements. Certain assumptions made in preparing the Forward-Looking Statements include that: the current COVID-19 pandemic will have limited adverse effect on the Company’s operations and its business plan; sales of EGRIFTA SV^® and Trogarzo^® in the United States will increase over time; the Company’s commercial practices in the United States and the countries of the European Union will not be found to be in violation of applicable laws; the long-term use of EGRIFTA SV^® and Trogarzo^® will not change their respective current safety profile; no recall or market withdrawal of EGRIFTA SV^® and Trogarzo^® will occur; no laws, regulation, order, decree or judgment will be passed or issued by a governmental body negatively affecting the marketing, promotion or sale of EGRIFTA SV^® and Trogarzo^® in countries where such products are commercialized; continuous supply of EGRIFTA SV^® and Trogarzo^® will be available; the Company’s relations with third-party suppliers of EGRIFTA SV^® and Trogarzo^® will be conflict-free and such third-party suppliers will have the capacity to manufacture and supply EGRIFTA SV^® and Trogarzo^® to meet market demand on a timely basis; no biosimilar version of EGRIFTA SV^® will be approved by the FDA; the Company’s intellectual property will prevent companies from commercializing biosimilar versions of EGRIFTA SV^® in the United States; Trogarzo^® will be reimbursed in key European countries; the FDA will approve the F8 formulation and the multi-dose pen injector; the FDA and the European regulatory agencies will approve a common design for the Phase 3 clinical trial studying tesamorelin for the treatment of NASH in the general population; the Company will succeed in conducting such Phase 3 clinical trial and its Phase 1 clinical trial using TH1902 in various types of cancer; the Company’s research and development activities using peptides derived from its oncology platform will yield positive results allowing for the development of new drugs for the treatment of cancer; the Company’s European infrastructure is adequate to commercialize Trogarzo^® in Germany and in other European countries; and the Company’s business plan will not be substantially modified.

Forward-Looking Statements assumptions are subject to a number of risks and uncertainties, many of which are beyond Theratechnologies’ 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, those related to or arising from: the adverse impact of the COVID-19 pandemic on (a) the Company’s sales efforts and sales initiatives, (b) the capacity of the Company’s suppliers to meet their obligations vis-à-vis the Company, (c) the Company’s research and development activities, (d) the health of the Company’s employees and its capacity to rely on its resources, as well as (e) global trade; the Company’s ability and capacity to grow the sales of EGRIFTA SV^® and Trogarzo^® successfully in the United States and Trogarzo^® in Europe; the Company’s capacity to meet supply and demand for its products; the market acceptance of EGRIFTA SV^® and Trogarzo^® in the United States and of Trogarzo^® in Europe; the continuation of the Company’s collaborations and other significant agreements with its existing commercial partners and third-party suppliers and its ability to establish and maintain additional collaboration agreements; the Company’s success in continuing to seek and maintain reimbursements for EGRIFTA SV^® and Trogarzo^® by third-party payors in the United States; the success and pricing of other competing drugs or therapies that are or may become available in the marketplace; the Company’s ability to protect and maintain its intellectual property rights in EGRIFTA SV^® and tesamorelin; the Company’s success in obtaining reimbursement for Trogarzo^® in key European countries, together with the level of reimbursement, if at all; the Company’s ability and capacity to commercialize Trogarzo^® in Germany and to launch Trogarzo^® in other key

OUR MEDICINES

The Company has two approved medicines for people living with HIV, namely Trogarzo^® in the United States, European Union (EU), and United Kingdom, and EGRIFTA SV^® in the United States. EGRIFTA^® is commercially available in Canada, but sales of EGRIFTA^® in Canada are not material to our business.

EGRIFTA SV^® is a new formulation of EGRIFTA^® that was approved by the FDA for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy and launched in the United States in November 2019. Unlike EGRIFTA^®, EGRIFTA SV^® can be kept at room temperature, comes in a single vial and has a higher concentration resulting in a smaller volume of administration.

Trogarzo^® was the first HIV treatment approved with a new mechanism of action in more than 10 years. It is the first in a new class of antiretrovirals (ARV) and is a long-acting ARV therapy that can lead to an undetectable viral load in heavily treatment-experienced adult HIV-infected patients when used in combination with other ARVs. The treatment is infused once every two weeks.

Trogarzo^® was approved by the FDA in March 2018 for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in heavily treatment-experienced adults with multidrug resistant (MDR) HIV-1 infection failing their current antiretroviral regimen. Trogarzo^® was also approved by the European Medicines Agency (EMA) in September 2019 for the treatment of adults infected with MDR HIV-1 for whom it is otherwise not possible to construct a suppressive antiviral regimen. Trogarzo^® is currently commercially available in Germany and the Company expects to launch Trogarzo^® in key additional European countries later in 2021 and in 2022. A number of patients are also being treated with Trogarzo^® in some European countries through early access programs. Trogarzo^® will be launched on a country-by-country basis across Europe as it gains public reimbursement in each such country. In addition, the Company has filed a marketing authorization application (MAA) in Israel for Trogarzo^®.

In March 2016, we obtained the rights to commercialize Trogarzo^® in the United States and Canada pursuant to a distribution and licensing agreement with TaiMed. In March 2017, the agreement was amended to include the commercial rights to Trogarzo^® in the EU and in other countries such as Israel, Norway, Russia and Switzerland (TaiMed Agreement).

The Company’s commercial strategy for the 2021 fiscal year is to generate revenue growth through increased sales of its medicines in the United States while working on securing an appropriate price and widespread reimbursement for Trogarzo^® in key European countries and launch Trogarzo^® in those key European countries.

Impact of the COVID-19 Pandemic

Throughout the global COVID-19 pandemic, face-to-face interactions in clinics, hospitals, AIDS services organizations and other offices were reduced, and patient treatment initiations were delayed due to restrictions implemented to stop the spread of COVID-19. In order to adapt to the pandemic environment, we transitioned to offering virtual interactions to continue to provide education and support for people in need of our medications, people living with HIV, case managers, healthcare providers and their staff, on how to manage HIV during the COVID-19 pandemic. In the fourth quarter of 2020, we announced a change to our U.S. sales infrastructure and a reallocation of resources to adapt to this new business environment and increase our presence in the healthcare community. During the first quarter of 2021, we continued to see some negative impact on our HIV revenues from the COVID-19 pandemic as many U.S. states maintained pandemic-related restrictions. In the EU, sales of Trogarzo^® and the review of regulatory dossiers continued to be adversely impacted by COVID-19 due to strict lockdown measures imposed in many European countries. We have and continue to impose measures to address and mitigate the impact of the COVID-19 pandemic on our employees and customers and to continue to progress our research and development programs. To date, preparations for our upcoming Phase 3 clinical trial of tesamorelin for the treatment of NASH have not been materially adversely impacted by the COVID-19 pandemic.

OUR PIPELINE

Theratechnologies has established a promising pipeline of investigational medicines in areas of high unmet need, including NASH, oncology and HIV.

Tesamorelin

In fiscal year 2020, the Company completed the evaluation and development of the F8 formulation, which based on internal studies, is bioequivalent to the original commercialized formulation of tesamorelin (F1 formulation). The F8 formulation has a number of advantages over the current formulation of EGRIFTA SV^®. Specifically, it is twice as concentrated resulting in a smaller volume of administration and is intended to be presented in a multi-dose vial that can be reconstituted once per week. Similar to the current formulation of EGRIFTA SV^®, the F8 formulation is stable at room temperature, even once reconstituted.

The F8 formulation is patent protected in the United States until 2033 and until 2034 in major European countries. The USPTO issued U.S. Patent 10,799,562 to MGH relating to the treatment of hepatic disease using growth hormone related hormone (GHRH) or analogues thereof which is scheduled to expire in 2040. This patent application claims, among other things, a method for the treatment of NAFLD or NASH in a patient via the administration of tesamorelin. Furthermore, on March 16, 2021, the USPTO issued U.S. Patent, No. 10,946,073, among other things, a method for preventing or delaying the onset of liver fibrosis or reducing liver fibrosis or its progression in a subject suffering from NAFLD or NASH. We have an exclusive worldwide license with MGH for these patents and continue to seek opportunities for additional patent registrations for the use of tesamorelin to further strengthen our intellectual property position.

The Company is currently working on the development of a multi-dose pen injector to be used in conjunction with the F8 formulation and we intend to seek marketing approval of the pen in the same sBLA as that for the F8 formulation. We plan to file an sBLA for the

Theratechnologies Inc.

2015 Peel Street, 11^th Floor

Montreal, Québec H3A 1T8

F8 formulation and multi-dose pen injector in early 2022 for the treatment of lipodystrophy in people living with HIV.

In November 2020, the Company filed an IND with the FDA for the Phase 3 clinical trial evaluating tesamorelin for the treatment of NASH and received a “Study May Proceed” letter for the Phase 3 trial from the FDA in December 2020. The IND filing followed our announcement made in September 2020 regarding our intent to develop tesamorelin for the treatment of NASH in the general population.

The proposed Phase 3 clinical trial design will enroll participants with liver-biopsy confirmed NASH and stage 2 or 3 fibrosis. Participants will be randomized 1:1 to receive 2 mg of tesamorelin or placebo. A second liver biopsy will be performed after 18 months of treatment for the first 900 participants, approximately. These data will form the basis for filing an sBLA with the FDA to seek accelerated approval. The primary endpoint used to seek accelerated approval will be the percentage of participants achieving NASH resolution and no worsening of fibrosis compared to placebo. Participants will remain in the Phase 3 trial for a total of 60 months. Subject to additional discussions with regulatory agencies, approximately 2,000 participants in total are expected to be enrolled, including a cohort of approximately 75 to 100 participants with HIV.

Theratechnologies intends to use the F8 formulation for the Phase 3 clinical trial in NASH. The Phase 3 trial in NASH will compare the F8 formulation to a placebo.

Per the FDA’s recommendation, the Company has confirmed a date to meet with the agency and discuss the proposed trial design and protocol. Concurrently, we are assessing our strategy regarding a filing with the EMA to initiate a Phase 3 clinical trial in the EU. Our goal is to initiate the Phase 3 clinical trial by the end of the third quarter of calendar year 2021. The timing of the trial initiation and the final number of patients enrolled are dependent upon any adjustments to the protocol and trial design as recommended by the FDA and EMA. The Company has retained the services of a global, large-scale CRO with experience in implementing large and late-stage clinical trials to assist with the execution of its Phase 3 clinical trial in NASH.

In March 2021, new data demonstrating the positive effect of tesamorelin in the circulation of immune activation markers associated with liver inflammation was presented at The Endocrine Society’s Annual Meeting, ENDO 2021. These data concluded that treatment with tesamorelin for 12 months decreased circulating markers of T-cell and monocyte/macrophage activity. A corresponding downregulation of immune pathways in the liver was also observed. These conclusions suggest that treatment with tesamorelin may contribute to better regulated immune activation in a population with metabolic dysregulation and systemic inflammation. The data comes from a sub-analysis of a double-blind, randomized, 12-month investigator-initiated trial studying the effect of tesamorelin on liver fat in 61 people infected with HIV with NAFLD, which was conducted by Dr. Steven Grinspoon, Professor of Medicine, Harvard Medical School, Chief of the Metabolism Unit at MGH. Dr. Grinspoon’s findings were published in The Lancet HIV in October 2019.

SORT1+ Technology^™

The Company is currently developing a platform of new proprietary peptides for cancer drug development targeting the SORT1 receptor. SORT1 is expressed in ovarian, triple-

7

Theratechnologies Inc.

2015 Peel Street, 11^th Floor

Montreal, Québec H3A 1T8

negative breast, skin, lung, colorectal and pancreatic cancers, among others. SORT1 plays a significant role in protein internalization, sorting and trafficking, and therefore, is an attractive target for anticancer drug development. Our innovative PDCs generated through our SORT1+ Technology^™ features distinct pharmacodynamic and pharmacokinetic properties that differentiate them from traditional chemotherapy. In contrast to traditional chemotherapy, our proprietary PDCs are designed to enable selective delivery of certain anticancer drugs within the tumor microenvironment, and more importantly, directly inside SORT1+ cancer cells.

Our SORT1+ Technology^™ was acquired in February 2019 as part of the acquisition of Katana Biopharma Inc., (Katana). Through the acquisition, Theratechnologies obtained the worldwide rights to this platform based on an exclusive royalty-bearing license entered into between Katana and Transfer Plus L.P.

Preclinical in vivo data has demonstrated that our SORT1+ Technology^™ improved anti-tumor activity and reduced neutropenia and systemic toxicity. It also was shown in preclinical models to bypass the multidrug resistance protein 1 (MDR1); also known as P- glycoprotein, one of the mechanisms of chemotherapy drug resistance. In addition, our SORT1+ Technology^™ has demonstrated activity in preclinical models against the formation of vasculogenic mimicry (VM) a mechanism also associated with cancer resistance. In vivo preclinical toxicity data have also demonstrated that TH1902 (docetaxel conjugate), could be administered at three times the MTD of docetaxel alone.

In December 2020, the Company filed an IND application with the FDA for the Phase 1 first-in-human clinical trial evaluating TH1902 for the treatment of various cancers. The proposed Phase 1 clinical trial design includes a dose escalation study to evaluate the safety, pharmacokinetics, MTD and preliminary anti-tumor activity of TH1902 administered once every three weeks in patients with advanced solid tumors refractory to available anti-cancer therapies. Once the MTD is determined, we expect a total of 40 additional patients will be enrolled to evaluate the potential anti-tumor activity of TH1902 in patients with endometrial, ovarian, colorectal, triple-negative breast and pancreatic cancers where it has been estimated that the sortilin receptor is expressed in 40% to 90% of cases.

In February 2021, we received fast track designation from the FDA for TH1902 as a single agent for the treatment of patients with SORT1+ recurrent advanced solid tumors that are refractory to standard therapy.

In March 2021, the Phase 1 trial was initiated. The Company has retained the services of a global, large-scale CRO to assist with the conduct of its Phase 1 clinical trial. The detailed study protocol is available at ClinicalTrials.gov under the identifier number: NCT04706962.

On April 10, 2021, new positive in vivo preclinical data on TH1902 were presented in two posters at the American Association for Cancer Research (AACR). These data demonstrated sustained tumor regression, better anti-tumor activity and tolerability with TH1902 compared to docetaxel alone in all cancer types studied, namely melanoma, pancreatic, ovarian, endometrial, colorectal and triple-negative breast cancers. The anti-tumor effect of TH1902 also persisted longer post-treatment than with docetaxel alone. In one poster, new data were presented on TH1902 in melanoma, which showed that

Montreal, Québec H3A 1T8

TH1902 was associated with superior anti-tumor effect and sustained post-treatment effect compared to docetaxel alone. Other data highlights included better and sustained anti-tumor effect in pancreatic tumors and in triple-negative breast cancer. A treatment effect was also observed in colorectal cancer, which is encouraging as docetaxel is not recognized as standardized care for colorectal cancer due to the lack of response. The positive effect of TH1902 on tumor regression was also observed in these cancer types at an equimolar quarter dose compared to docetaxel alone. In a second poster, new data highlighted the sustained inhibition of ovarian and endometrial cancers with TH1902 at equimolar doses of docetaxel alone. Specifically, TH1902 showed improved anti-tumor activity in endometrial cancer at an equimolar quarter dose compared to docetaxel alone. Furthermore, these data showed that in all cancers studied, neutropenia was absent after six consecutive treatments with TH1902 at an equivalent dose of the maximum tolerated dose (MTD) of docetaxel, whereas a single treatment of docetaxel strongly reduced neutrophil counts.

In addition, further preclinical research activities are being conducted using TH1904, our second investigational PDC (doxorubicin conjugate). In vitro and in vivo experiments using TH1904 have demonstrated results similar to those obtained with TH1902 and support the development of additional investigational compounds using our SORT1+ Technology^™ that may help in the fight against cancer.

Ibalizumab for HIV

A study evaluating an IV push administration of Trogarzo^® is currently being conducted by TaiMed. Enrollment in this study is now complete and TaiMed expects to complete the trial in the third quarter of 2021. The study is evaluating the drug levels of Trogarzo using the IV push administration versus the approved IV infusion method of administration. The IV study is being conducted and funded by TaiMed. Theratechnologies and TaiMed are also planning to evaluate an IM method of administration for Trogarzo^®. The study will be conducted and funded by Theratechnologies. Under the terms of the TaiMed Agreement, we are entitled to commercialize the new methods of administration of Trogarzo^® if, and when, approved.

In connection with the September 2019 approval of Trogarzo^® in Europe, the EMA has requested a post-authorization efficacy study (Registry) to be conducted to evaluate the long-term efficacy and durability of Trogarzo^® in combination with other antiretrovirals. The enrollment of patients in this study is expected to begin in late 2021. The Company is also required to conduct a pediatric investigation plan (PIP) to evaluate Trogarzo^® in children aged 6 to <18 years old. The PIP will be comprised of two studies with the first study expected to begin in the second half of 2021.

2021 BUSINESS STRATEGY AND OBJECTIVES

Our 2021 Business Strategies and Objectives are as follows:

Theratechnologies Inc.

2015 Peel Street, 11^th Floor

Montreal, Québec H3A 1T8

First-Quarter Fiscal 2021 Financial Results

Revenue

Consolidated revenue for the three-month period ended February 28, 2021 was $15,430,000 compared to $15,719,000 for the same period ended February 29, 2020.

For the first quarter of fiscal 2021, net sales of EGRIFTA SV^® reached $8,688,000 compared to $8,515,000 in the first quarter of the prior year, representing an increase of 2.0% over the first quarter of 2020, which included sales of both EGRIFTA SV^® and EGRIFTA^®.

In the first quarter of fiscal 2021, Trogarzo^® net sales amounted to $6,742,000 compared to $7,204,000 for the same quarter of 2020, representing a decrease of 6.4%. Lower sales of Trogarzo^® were a result of a decrease in unit sales, and higher rebates, which were offset by a higher selling price.

Cost of Sales

For the three months ended February 28, 2021, cost of sales was $5,411,000 compared to $6,761,000 for the same quarter in fiscal 2020, primarily due to the lower cost of goods sold. Cost of goods sold was $4,190,000 in the first quarter of 2021 compared to $5,400,000 for the same quarter the previous year. The decrease in cost of goods sold was mainly due to a combination of lower Trogarzo^® sales, a lower cost for Trogarzo^® and a lower cost of EGRIFTA SV^® compared to EGRIFTA^®. Cost of sales also included the amortization of the other asset of $1,221,000 in both Q1 2021 and Q1 2020.

R&D Expenses

R&D expenses amounted to $4,883,000 in the three-month period ended February 28, 2021 compared to $3,419,000 for the same period in 2020. The increase was largely due to higher spending in our oncology and NASH programs, increased spending in medical and patient education, as well as increased medical affairs spending in Europe.

Selling Expenses

Selling expenses amounted to $6,158,000 for the first quarter of 2021 compared to $6,361,000 for the same three-month period last year, reflecting a realignment of spending as a result of a lower headcount in our salesforce.

The amortization of the intangible asset value for the EGRIFTA^® and Trogarzo^® commercialization rights is also included in selling and market development expenses. As such, we recorded an expense of $795,000 for the first quarter of fiscal 2021 compared to $642,000 for the same quarter last year.

General and Administrative Expenses

General and administrative expenses amounted to $3,562,000 for the three months ended February 28, 2021 compared to $2,570,000 for the first quarter of 2020. The increase in general and administrative expenses was mainly associated with an overall increase in business activities and increased activity in Europe.

Finance Income

Finance income, consisting of interest income, amounted to $25,000 during the first quarter of 2021 compared to $166,000 in the first quarter of last year. Lower finance income was due in large part to a decreased liquidity position and a decrease in interest rates.

Finance Costs

Finance costs for the three months ended February 28, 2021 were $1,357,000 compared to $1,318,000 for the comparable period of 2020. Finance costs in the first quarter of 2021 and 2020 included interest of $802,000 on the senior convertible notes issued in June 2018.

Finance costs also included accretion expense of $581,000, compared to $502,000 for the comparable period in 2020.

Adjusted EBITDA

Adjusted EBITDA was $(1,821,000) for the first quarter of 2021 compared to $(994,000) for the same period of 2020. See “Non-IFRS Financial Measures” below.

Net loss

Taking into account the revenue and expense variations described above, we recorded a net loss of $5,922,000 or $0.07 per share in the first three months of fiscal 2021 compared to a net loss of $4,544,000 or $0.06 per share for the same period last year.

Financial Position

We ended the first quarter of fiscal 2021 with $56,716,000 in cash, bonds and money market funds.

During the first quarter of fiscal 2021, the Company completed a public offering for the sale and issuance of 16,727,900 units of the Company for a gross cash consideration of $46,002,000 including the full exercise of the over-allotment option. Share issue costs amounted to $3,385,000 resulting in net proceeds of $42,617,000.

Each unit is comprised of one common share of the Company and one-half of one common share purchase warrant of the Company (each whole warrant, a “Warrant”). Each Warrant entitles the holder to purchase one common share of the Company at an exercise price of $3.18 until January 19, 2024.

Our current cash, bond and money market funds will be sufficient to fund the Company’s operations for the foreseeable future.

For the three-month period ended February 28, 2021, operating activities used $5,228,000 compared to $4,825,000 in the comparable period of fiscal 2020, primarily due

11

Theratechnologies Inc.

to the increased loss in 2021, partially offset by a smaller negative impact of changes in operating assets and liabilities.

In the first quarter of fiscal 2021, changes in operating assets and liabilities had a negative impact on cash flow of $3,332,000 (2020-negative impact of $3,832,000). These changes included a negative impact from accounts payables and accrued liabilities and inventories, and were offset by a decrease in trade and other receivables and an increase in provisions.

Factors Affecting the Variability of Quarterly Results

There are quarter-over-quarter variations in net sales revenue, principally due to changes in distributor inventory levels with some additional impact from time to time related to average net selling price, which is affected by changes in the mix of private payors versus government drug reimbursement plans.

Subsequent Events

Warrants

Since the end of the first quarter ended February 28, 2021, 177,850 Warrants, issued in January 2021 (see “Financial Position”), were exercised and 177,850 common shares were issued for a cash consideration of $566,000.

Stock options

Between March 1, 2021 and April 12, 2021, 100,000 options were exercised, and 100,000 common shares were issued for a cash consideration of $30,000.

Milestone oncology

In March 2021, the Company issued 481,928 common shares under the terms of the acquisition agreement entered into with all of the shareholders of Katana for Katana’s in-licensed oncology platform. The purchase price for the oncology platform provided for share-based consideration to be issued upon attainment of two milestones. The first milestone consisted in initiating a Phase 1 clinical trial evaluating TH1902 for the treatment of sortilin positive solid tumors. This milestone was achieved in March 2021. The estimated fair value of the share-based consideration of $614,000, initially recorded in contributed surplus on the date of the acquisition, will be reclassified to share capital in the second quarter.

Recent Changes in Accounting Standards

There were no changes in accounting standards during the first quarter of fiscal 2021. .

Outstanding Share Data

As of April 12, 2021, the Company had 94,601,089 common shares issued and outstanding, 8,186,100 warrants outstanding, and 4,100,758 outstanding options. We also had $57,500,000 aggregate principal amount of 5.75% convertible unsecured senior notes due June 30, 2023 issued and outstanding as a result of the Offering. These notes are convertible into common shares at the option of the holder at a conversion price of $14.85, representing a conversion rate of approximately 67.3401 common share per $1,000 principal amount of notes. The conversion of all of the outstanding notes would result in the issuance of 3,872,055 common shares.

Contractual Obligations

There was no material change in contractual obligations during the three-month period ended February 28, 2021.

Economic and Industry Factors

The WHO declared a global pandemic on March 11, 2020. Authorities around the world implemented confinement measures designed to curb the spread of the COVID-19. Those measures have severely limited face-to-face access to healthcare providers. The industry as a whole has had to adapt to this new reality and uncertainty remains.

Internal Control

There was no change in the Company’s internal control over financial reporting, or ICFR, that occurred during the period beginning on December 1, 2020 and ending on February 28, 2021 that has materially affected, or is reasonably likely to materially affect, the Company’s ICFR.

Non-IFRS Financial Measures

Reconciliation of net profit or loss to adjusted earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA)

Adjusted EBITDA is a non-IFRS financial measure. A reconciliation of the Adjusted EBITDA to net loss is presented in the table below. We use adjusted financial measures to assess our operating performance. Securities regulations require that companies caution readers that earnings and other measures adjusted to a basis other than IFRS do not have standardized meanings and are unlikely to be comparable to similar measures used by other companies. Accordingly, they should not be considered in isolation. We use Adjusted EBITDA to measure operating performance from one period to the next without the variation caused by certain adjustments that could potentially distort the analysis of trends in our business, and because we believe it provides meaningful information on our financial condition and operating results.

We obtain our Adjusted EBITDA measurement by adding to net profit or loss, finance income and costs, depreciation and amortization, and income taxes. We also exclude the effects of certain non-monetary transactions recorded, such as share-based compensation and write-downs (or related reversals) of inventories, for our Adjusted EBITDA calculation. We believe it is useful to exclude these items as they are either non-cash expenses, items that cannot be influenced by management in the short term, or items that do not impact core operating performance. Excluding these items does not imply they are necessarily nonrecurring. Share-based compensation costs are a component of employee remuneration and can vary significantly with changes in the market price of the Company’s shares. In addition, other items that do not impact core operating performance of the Company may vary significantly from one period to another. As such, Adjusted EBITDA provides improved continuity with respect to the comparison of our operating results over a period of time. Our method for calculating Adjusted EBITDA may differ from that used by other companies.
