AB Science announces the success of its capital increase by private placement for an amount of 15 million euros



Paris, April 24, 2023, 8am CET

AB Science S.A. (the “Company” or “AB Science”, NYSE Euronext – FR0010557264 – AB), announces today the success of its capital increase through the issuance of new ordinary shares with attached warrants, with a waiver of preferential subscription rights, via a private placement for a final amount of 15.0 million euros (the “Capital Increase”).

Alain Moussy, Chief Executive Officer of AB Science, states:

« AB Science is satisfied with the success of this capital increase, through which AB Science's historical shareholders have had the opportunity to renew their confidence in AB Science and to show their support for its new strategy announced on April 21. »

AB Science has decided to focus its development strategy as follows:

  • Allocation of current resources primarily to the development of masitinib for the treatment of amyotrophic lateral sclerosis and the development of the microtubule destabilizer agents (MDA) platform, with the clinical development of AB8939 in refractory acute myeloid leukemia and the initiation of regulatory preclinical development of a new oral molecule in the same microtubule class for sarcoma and solid tumors.

We want to focus the majority of our clinical resources on the development of rare diseases with masitinib, on the development of the microtubule platform with AB8939 and future molecules of the same family due to the very encouraging first results.

  • Acceleration of the process of seeking a license for masitinib in non-rare disease indications, with priority given to progressive forms of multiple sclerosis and Alzheimer's disease.

This acceleration is possible now that the confirmatory Phase 3 studies have been approved by the FDA in the United States and the major European agencies. To this end, the Company has retained the services of a leading investment bank.

This license search is a priority in the Company's strategy, given the number of clinical studies already conducted and the maturity of the pipeline, and given the additional investments required to complete the clinical program, up to market authorizations. We want to highlight that the duration of this license search is not predictable and that the realization of a license is dependent on a number of factors and is not guaranteed. However, the milestones reached at this stage are essential factors that contribute to the feasibility of this strategy.

As a result of the focus strategy, AB Science has decided to adapt its organization, which should lead to a significant reduction in costs. This strategic focus reinforces and sustains the existing agreement between certain shareholders of AB Science and Alain Moussy.

Terms of the Capital Increase

The Capital Increase consisted of a private placement pursuant to Articles L. 225-136 of the French Commercial Code and L. 411-2 1° of the French Monetary and Financial Code and has been carried out with a waiver of preferential subscription rights, pursuant to the delegation of authority granted to the Board of Directors under the 20th resolution of the Combined General Shareholders’ Meeting of June 29, 2022. The Capital Increase has taken the form of the issuance of 2,608,686 actions new ordinary shares (the “New Shares”) to each of which are attached a share subscription warrant (the “Warrants”).

The Capital Increase was made through a cash contribution of approximately EUR 11.5 million and by offsetting existing receivables, i.e. approximately EUR 3.0 million (receivables related to the pre-financing of the research tax credit for the 2020 financial year and maturing in 2023, as well as approximately EUR 500,000 in interest accrued to date on the convertible bonds issued in February 2022).

Two warrants giving the right to subscribe to one ordinary share, all of the 2,608,686 New Shares and all of the 1,304,343 new shares that would be issued upon exercise of the warrants, i.e. a total of 3,913,029 shares in the Company, represent 7.36% of the Company's current share capital.

The issue price of the New Shares has been set at 5.75 euros (0.01 euro par value and 5.74 euros issue premium) and the exercise price of the Warrants at 8.625 euros, representing a total fundraising of approximately EUR 15.0 million (taking into account the exercise of the warrants, the maximum amount of the Capital Increase could be increased by an amount of 26.3 million euros).

The Warrants may be exercised from January 1st, 2025 to December 31, 2030, will be immediately detached from the New Shares upon their issuance and will not be listed.

The settlement-delivery of the new ordinary shares to be issued in the context of the Capital Increase and their listing on Euronext Paris are expected to occur on April 28, 2023 at the latest. The new shares will bear current dividend rights and will be listed on the regulated market on Euronext Paris under ISIN code: FR0010557264 – AB.

The proceeds of the Capital Increase will provide AB Science with the additional resources necessary to finance its activities over the next twelve months. In particular, the raised funds will be used for the clinical development of masitinib in amyotrophic lateral sclerosis and other orphan indications and for the development of the AB Science microtubule destabilizer agents platform. The Capital Increase will also support the strategy communicated on April 21.

Shareholding structure of the Company after the Capital Increase

After the Capital Increase (excluding the exercise of the Warrants), the share capital of the Company will amount to 558,081.39 euros, and will be composed of 55,808,139 shares with a nominal value of 0.01 euro each (all share classes included).

By way of illustration, a shareholder holding 1% of the Company's share capital (including all categories of shares) prior to the Capital Increase and who did not participate in the Capital Increase will hold 0.95% of the Company's share capital after the Capital Increase and 0.93% in the event that all the Warrants are exercised.

About masitinib
Masitinib is a novel oral tyrosine kinase inhibitor that targets mast cells and macrophages, key immune cells, through inhibition of a limited number of kinases. Due to its unique mode of action, masitinib can be developed in a wide range of diseases, including oncology, inflammatory diseases, and certain central nervous system diseases. In oncology, through its immunotherapy activity, masitinib may have an effect on survival, alone or in combination with chemotherapy. Through its activity on mast cells and microglial cells and therefore its inhibitory effect on the activation of the inflammatory process, masitinib may have an effect on the symptoms associated with certain inflammatory and central nervous system diseases.

About AB8939
AB8939 is a new synthetic microtubule-destabilizing drug. Preclinical data show that AB8939 has broad anticancer activity, with a notable advantage over standard chemotherapies that target microtubules of being able to overcome P-glycoprotein (Pgp) and myeloperoxidase (MPO) mediated drug resistance. Development of drug resistance often restricts the clinical efficacy of microtubule-targeting chemotherapy drugs (for example, taxanes and vinca alkaloids); thus, AB8939 has strong potential to be developed in numerous oncology indications.
