At its meeting of Wednesday, 26 January 2022, BOOSTHEAT's Board of Directors noted a bond issue of €3 million subscribed entirely by the company HOLDIGAZ to support BOOSTHEAT's action plan implementation.


The financing of €3 million will be in the form of a bond issue with the option of redemption in cash or in shares at the company's discretion. The bond subscribed will bear interest at a rate of 1% and mature on 31 December 2024. In addition, the Board of Directors has decided to align at the same date the maturity date of the bonds issued in July 2021, which were subscribed by the main shareholders[1].


The Company will have the option of early redemption of the principal amount of the bonds and interest either in cash or, subject to the necessary authorizations, in the Company shares by means of offsetting receivables. The price of the shares has been set at €1.1507, corresponding to the weighted average share price during the 20 trading sessions preceding the date of the Board of Director ‘s decision concerning the bond issue.


As of 31 December 2021, the company had €3.5 million of cash available, the same level as of June 30, 2021. At the same date, the company also had €8 million available on its equity financing line[2]. With this new financing, BOOSTHEAT estimates that it has resources needed to cover all of its needs in 2022.


"After 6 months of a structuring and ambitious roadmap implementation and after having demonstrated very good results of reliability and performance in laboratory and on the field, this financing is a mark of confidence and an incentive encouragement from our historical shareholder ", says Eric Lambert, CEO of BOOSTHEAT.
