Information expressed or implied by such statements relates to forecasts, growth and the business strategy of BOOSTHEAT and are based on analyses of forecasted results and market estimates. By its nature, prospective information is subject to risks and uncertainties because it relates to events and depends on circumstances that may or may not occur in the future. In no event should such prospective information be understood to constitute a guarantee of BOOSTHEAT's future performance, financial condition, results of operations or actual cash flows, and changes in the markets in which BOOSTHEAT operates may differ materially from those described or implied by the forward-looking statements contained in this press release. Even if BOOSTHEAT's financial condition, results of operations and cash flows and the changes in the markets in which it operates are consistent with the forward-looking statements contained in this press release, such statements may be unreliable indicators of BOOSTHEAT's actual future results or changes with respect to BOOSTHEAT and its markets. A description of factors that may have a significant adverse effect on BOOSTHEAT's business, financial condition or results of operations, or on its ability to achieve its targets and objectives, is contained in Chapter 3 “Risk Factors” of the registration document and chapter 2 “Risk factors associated with the offering” of the securities note.


No communication and no information in respect of the offering by BOOSTHEAT of the shares (the ”Shares”) may be distributed to the public in any jurisdiction where a registration or approval is required. No steps have been or will be taken outside of France in any jurisdiction where such steps would be required. The offering and subscription of the Shares may be subject to specific legal or regulatory restrictions in certain jurisdictions. BOOSTHEAT assumes no responsibility for any violation of any such restrictions by any person.

This press release constitutes promotional material only and not a prospectus within the meaning of Regulation (EU) 2017/1129 of the European Parliament and the Council of June 14, 2019 (the “Prospectus Regulation”).

In France, an offer to the public of securities may only be made pursuant to a prospectus approved by the AMF. With respect to the member States of the European Economic Area other than France (each, a “relevant member State”) no action has been undertaken or will be undertaken to make an offer to the public of the securities requiring a publication of a prospectus in any relevant member State. As a result, the Shares may only be offered in relevant member States: (a) to legal entities that are qualified investors as defined in Directive 2014/65/EU of the European Parliament and the Council of May 15, 2014 on markets in financial instruments (“MiFID II”); (b) in any other circumstances that do not require the publication by BOOSTHEAT of a prospectus pursuant to Article 3(2) of the Prospectus Regulation.

For the purposes of this paragraph, the notion of an “offer to the public of Shares” in each of the relevant member States, means any communication, to individuals or legal entities, in any form and by any means, of sufficient information on the terms and conditions of the offering and on the Shares to be offered, thereby enabling an investor to decide to purchase or subscribe for the Shares.

This selling restriction comes in addition to the other selling restrictions applicable in the other member States.

The distribution of this press release is not made, and has not been approved, by an “authorised person” within the meaning of Article 21(1) of the Financial Services and Markets Act 2000. As a consequence, this press release is directed only at persons who are (x) located outside the United Kingdom or (y) located in the United Kingdom and who (i) have professional experience in matters relating to investments and fall within Article 19(5) (“investment professionals”) of the Financial Services and Markets Act 2000 (Financial Promotions) Order 2005, as amended (the “Order”), (ii) are persons falling within Article 49(2)(a) to (d) (high net worth companies, unincorporated associations, etc.) of the Order or (iii) are persons to whom this press release may otherwise lawfully be communicated (all such persons in (y)(i), (y)(ii) and (y)(iii) together being referred to as “Relevant Persons”). The securities are directed only at Relevant Persons and no invitation, offer or agreements to subscribe, purchase or otherwise acquire securities may be proposed or made other than with Relevant Persons. Any person other than a Relevant Person may not act or rely on this document or any provision thereof. This press release is not a prospectus which has been approved by the Financial Services Authority or any other United Kingdom regulatory authority for the purposes of Section 85 of the Financial Services and Markets Act 2000.

This press release does not constitute or form a part of any offer or solicitation to purchase or subscribe for securities nor of any offer or solicitation to sell securities in the United States. The securities mentioned herein have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), and may not be offered or sold, directly or indirectly, within the United States except pursuant to an exemption from or in a transaction not subject to, the registration requirements of the Securities Act. BOOSTHEAT does not intend to register any portion of the proposed offering in the United States nor to conduct a public offering of securities in the United States.

The distribution of this document in certain countries may constitute a breach of applicable law. The information contained in this document does not constitute an offer of securities for sale in the United States, Canada, Australia or Japan.

This press release may not be published, forwarded or distributed, directly or indirectly, in the United States, Canada, Australia or Japan.

The prospectus registered with the Autorité des marchés financiers contains forward-looking statements. No guarantee is given as to these forecasts being achieved, which are subject to risks, including those described in the prospectus, and to the development of economic conditions, the financial markets and the markets in which BOOSTHEAT operates.

In case of exercise of the over-allotment option, Gilbert Dupont (or any entity acting on its behalf), acting as a stabilizing agent in the name and on behalf of the underwriters may, without being bound and having the right to terminate at any time, during a period of 30 calendar days following the date on which the price for the offering is determined, i.e., according to the indicative timetable, from October 8, 2019 up to and including November 8, 2019, carry out transactions with a view to maintaining the market price of BOOSTHEAT shares in a manner consistent with applicable laws and regulations and, in particular, Regulation (EU) No. 596/2014 of the European Parliament and of Council of April 16, 2014 supplemented by Commission Delegated Regulation (EU) 2016/1052 of March 8, 2016. Any stabilizing action aims to support the market price of BOOSTHEAT shares and may affect the share price.

Information to distributors

Solely for the purposes of the product governance requirements contained within: (a) MiFID II; (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the “MiFID II Product Governance Requirements”), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any “manufacturer” (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the shares offered in the offering (the “Offered Shares”) have been subject to a product approval process, which has determined that the Offered Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the “Target Market Assessment”). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Offered Shares may decline and investors could lose all or part of their investment; the Offered Shares offer no guaranteed income and no capital protection; and an investment in the Offered Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom.

The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the offering.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment for any particular client of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Offered Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the shares and determining appropriate distribution channels.
