Inventiva announces the implementation of an At-The-Market program in the United States

Daix (France), August 2, 2021 (GLOBE NEWSWIRE) – Inventiva S.A. (NASDAQ: IVA – EURONEXT PARIS: IVA) (the "Company”), a clinical-stage biotechnological company focused on the development of oral small molecule therapies for the treatment of patients with significant unmet medical need in the areas of fibrosis, lysosomal storage disorders and oncology, today announced the implementation of an At-The-Market ("ATM”) program allowing the Company to issue and sell, including with unsolicited investors who have expressed an interest, ordinary shares in the form of American Depositary Shares ("ADS”), each ADS representing one ordinary share of Inventiva, with aggregate gross sales proceeds of up to $100,000,000 (subject to a regulatory limit of 20% dilution and within the limits of the investors' requests expressed in the context of the program), from time to time, pursuant to the terms of a sale agreement with Jefferies LLC ("Jefferies”), acting as sales agent. The timing of any issuances in the form of ADSs will depend on a variety of factors. The ATM program will be effective until August 2, 2024, unless terminated prior to such date in accordance with the sale agreement or the maximum number of ADSs to be sold thereunder has been reached.

The Company currently intends to use the net proceeds, if any, of sales of ADSs issued under the program to fund the research and development of its product candidates, and for working capital and general corporate purposes.

Jefferies, as sales agent, will use commercially reasonable efforts to arrange on the Company’s behalf for the sale of all ADSs requested to be sold by the Company, in accordance with standard market practices. Sales prices may vary based on market prices and other factors. Only eligible investors (as described in greater detail below) may purchase ADSs under the ATM program.

The ADSs and the underlying ordinary shares will be issued through a capital increase without shareholders’ preferential subscription rights under the provisions of Article L. 225-138 of the French Commercial Code (Code de commerce) and pursuant to the 20^th resolution adopted by the annual general meeting of shareholders held on April 16, 2021 (or any substitute resolutions, adopted from time to time), for an aggregate offering amount of up to $100.0 million, being specified that the maximum number of new shares to be admitted on the regulated market of Euronext Paris is capped at 20% of the number of shares admitted to trading on such market, including shares admitted without prospectus during the last twelve months at the date of their issuance. The new ordinary shares to be sold in the form of ADSs would be issued in one or more offerings at the market price of each offering of the ADSs at the time of pricing of the considered capital increase.

The ATM program may only be issued to the categories of investors defined in the 20^th resolution adopted by the annual general meeting of shareholders held on April 16, 2021 (or any similar resolutions that may be substituted to them in the future), comprising (i) natural or legal persons (including companies) trusts or investment funds, or other investment vehicles, in any form, established under French or foreign law, which regularly invest in the pharmaceutical, biotechnological or medical technology sectors, and/or (ii) companies, institutions or entities, in any form, French or foreign, exercising a significant part of its activities in the pharmaceutical, cosmetic or chemical sectors, or medical devices and/or technologies, or researching in such sectors. The new ordinary shares will be admitted to trading on the regulated market of Euronext in Paris and the issued ADSs will trade on the Nasdaq Global Market ("Nasdaq”).

On an illustrative basis, assuming the issuance of the full amount of 7,593,015 ADSs at an assumed offering price of $13,17 (or €11,36¹), the last reported sale price of the ADSs on Nasdaq on July 29, 2021, for the maximum gross proceeds of $100,000,000 (or €84,224,712.50²) under the ATM program, a holder of 1.0% of the outstanding Company's share capital as of the date of this press release, would hold 0.84% of the outstanding Company's share capital after the completion of the transaction (calculated on the basis of the number of outstanding shares on the date of publication of this press release).

During the term of the ATM program, the Company will include in the publication of its quarterly results information about its use of the program during the preceding quarter and will also provide an update after each capital increase on a dedicated location on its corporate website in order to inform investors about the main features of each issue that may be completed under the ATM program from time to time.

A shelf registration statement on Form F-3, including a base prospectus relating to Inventiva’s securities and a sales agreement prospectus relating to the ATM program, was filed with the SEC, but has not yet become effective. The securities referred to in the registration statement may not be sold, nor may offers to buy them be accepted, prior to the time the registration statement becomes effective. Before purchasing ADSs in the offering, prospective investors should read the base prospectus and the accompanying sales agreement prospectus, together with the documents incorporated by reference therein. Prospective investors may obtain these documents for free by visiting EDGAR on the SEC’s website at www.sec.gov. Alternatively, a copy of the base prospectus and the accompanying sales agreement prospectus relating to the offering may be obtained from Jefferies LLC, 520 Madison Avenue, New York, NY 10022 or by telephone at (877) 821-7388 or by email at Prospectus_Department@Jefferies.com.
