Forward-Looking Statements

This press release contains “forward-looking statements” within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical fact, included in this press release are forward-looking statements. These statements include, but are not limited to, forecasts and estimates regarding Inventiva's cash resources and expenses, forecasts and estimates with respect to Inventiva’s NATiV3 Phase 3 clinical trial with lanifibranor in patients with MASH, including the quality of trial results, design, duration, timing, costs, and funding, timing of clinical trial data releases and publications, the information, insights and impacts that may be gathered from clinical trials, the potential therapeutic benefits of lanifibranor, potential regulatory submissions, approvals and commercialization, Inventiva’s pipeline and development plans, and Inventiva's future activities, expectations, plans, growth and prospects. Some of these statements, forecasts, and estimates may be identified by the use of words such as, without limitation, “believe,” “anticipate,” “expect,” “intend,” “plan,” “seek,” “estimate,” “may,” “will,” “could,” “should,” “designed,” “hope,” “target,” “potential,” “opportunity,” “possible,” “aim,” and “continue” and other similar expressions. These statements are not historical facts, but rather statements of future expectations and other forward-looking statements based on management's beliefs. These statements reflect the opinions and assumptions prevailing as of the date of the statements and involve known and unknown risks and uncertainties that could cause future results, performance, or events to differ materially from those expressed or implied in such statements. Actual events are difficult to predict and may depend on factors beyond Inventiva's control. There can be no guarantee, with respect to product candidates, that clinical trial results will be available on schedule, that future clinical trials will be initiated as planned, that product candidates will receive the necessary regulatory approvals, or that the milestones planned by Inventiva or its partners will be achieved on schedule, or even at all. Future results may differ materially from the anticipated future results, performance, or achievements expressed or implied by these statements, forecasts, and estimates due to a number of factors, including the fact that interim data or data from any interim analysis of ongoing clinical trials do not predict the future results of clinical trials, the fact that the DMC's recommendation does not prejudge any eventual marketing authorization, that Inventiva cannot provide assurance on the impacts of the Suspected Unexpected Serious Adverse Reaction (SUSAR) on recruitment or the final impact on the results or timing of the NATiV3 trial or related regulatory issues, Inventiva is a clinical-stage company with no approved products and no historical revenue, Inventiva has incurred significant losses since its inception, Inventiva has never generated revenue from product sales, Inventiva will need additional capital to fund its operations, without which Inventiva may be required to significantly reduce its activities, delay or discontinue one or more of its research or development programs, expand its activities or capitalize on its business opportunities, and may not be able to continue as a going concern. Inventiva's ability to obtain financing and complete potential transactions on a timely basis, as well as whether, when, and to what extent dilutive instruments may be exercised and by which holders, Inventiva's future success depends on the successful clinical development, regulatory approvals, and subsequent commercialization of lanifibranor, preclinical studies or previous clinical trials are not necessarily predictive of future results, and the results of Inventiva's and its partners' clinical trials may not support Inventiva's and its partners' claims regarding product candidates, Inventiva's expectations regarding its clinical trials may prove to be incorrect, and regulatory authorities may require additional stops and/or modifications to Inventiva's clinical trials. Inventiva's expectations regarding the clinical development plan for lanifibranor for the treatment of MASH may not be realized and may not support the approval of a New Drug Application, Inventiva's ability to implement its commercialization, marketing, and manufacturing capabilities and strategy, Inventiva's ability to successfully cooperate with its existing partners or enter into new partnerships, and to fulfil its obligations under any agreements entered into in connection with such partnerships, the benefits of its current and future partnerships on the clinical development, regulatory approvals, and, if applicable, commercialization of its product candidates, as well as the achievement of milestones and timelines anticipated in connection with such partnerships, Inventiva and its partners may encounter substantial delays beyond expectations in their clinical trials or fail to demonstrate safety and efficacy to the satisfaction of the applicable regulatory authorities, the ability of Inventiva and its partners to recruit and retain patients in clinical studies, the recruitment and retention of patients in clinical trials is a costly and time-consuming process that could be made more difficult or impossible by multiple factors beyond the control of Inventiva and its partners, Inventiva's product candidates may cause adverse reactions or have other properties that could delay or prevent their regulatory approval, or limit their commercial potential, Inventiva faces significant competition, and Inventiva's activities, preclinical studies, and clinical development programs, as well as timelines, Inventiva's financial condition and results of operations could be materially and adversely affected by changes in laws and regulations, adverse conditions in its industry, geopolitical events, such as the conflict between Russia and Ukraine and the resulting sanctions, the conflict in the Middle East and the related risk of a wider conflict and ongoing conflicts, epidemics, and macroeconomic conditions, including changes in international trade policies, global inflation, fluctuations in financial and credit markets, customs duties and other trade barriers, political unrest and natural disasters, uncertain financial markets, and disruptions in banking systems. In light of these risks and uncertainties, no representation is made as to the accuracy or completeness of these forward-looking statements, forecasts, and estimates. Furthermore, forward-looking statements, forecasts, and estimates are only valid as of the date of this press release. Readers are cautioned not to place undue reliance on these forward-looking statements.
