STENTYS announces plans to acquire MINVASYS, French specialist in innovative solutions for the treatment of cardiovascular disorders, with a view to creating a benchmark French group in interventional cardiology

• • Expansion and complementarity of the proprietary product range

• • Extension of the sales coverage

• • Accretive acquisition on the operating income with significant operational synergies

• • Pro-forma consolidated revenues1 at December 31, 2017 estimated at approximately €12 million

• • Operation to be financed via a €7 to 9 million rights issue to which Bpifrance would contribute

PARIS - January 30, 2018 - 6 pm CET - STENTYS (FR0010949404 - STNT), a medical technology company commercializing the Xposition S self-apposing coronary stent, today announces that it has signed an exclusive negotiations agreement with a view to acquiring 100% of the French company MINVASYS, independent specialist in innovative coronary devices marketed worldwide. This planned acquisition for approximately €7.5 million (essentially in cash, as well as in STENTYS shares for approximately €1 million) would be financed through a €7 to 9 million capital increase, to which Bpifrance would participate, that would also strengthen the Group's financial structure.

This acquisition, subject to the success of the capital increase, would allow STENTYS to broaden its proprietary product portfolio and generate significant commercial, organizational and production synergies with an accretive impact on STENTYS' results.

Christophe Lottin, Chief Executive Officer of STENTYS, declares: "This strategic acquisition would represent a major milestone in STENTYS' development. It would confirm our intention to accelerate the transition that is already underway and would also lead to a consolidation of French companies capable of innovating and providing new therapeutic solutions on an increasingly competitive and regulated cardiovascular market. In conjunction with the acceleration in our growth, the combination of our two companies would lead to substantial synergies, enabling us to further optimize our cost structure. In order to finance this acquisition project and accelerate our development, we plan to shortly launch a rights issue of between €7 and 9 million, and I am delighted to already be able to count on the support of our core shareholder, Bpifrance, which holds 4.94% of STENTYS' shares and would intend to participate in this operation aiming to make STENTYS a benchmark French group in the cardiovascular sector."

MINVASYS: a French specialist in minimally invasive vascular systems with a strong international reach

Founded in the Paris region in 2003, MINVASYS is an independent company specialized in Minimally INvasive VAscular SYStems (whence the name) that markets a broad range of coronary products, including drug-eluting stents, dilatation balloons, drug-eluting balloons, thrombo-aspiration catheters and accessories such as valve Y connectors. In 2016, the Company reported revenues of €5 million, most of which was generated overseas thanks to a network of distributors covering over 42 countries.

MINVASYS is a profitable company that generated a slight net profit in 2016. The implementation of this acquisition project would thus have an accretive effect on STENTYS' results.

MINVASYS holds 9 patents, including the Nile concept, an all-in-one unique system comprising of a coronary stent and two integrated balloons for the simultaneous treatment of both arteries of a complex coronary bifurcation.

MINVASYS employs 11 people in France.
