PARIS - July 12, 2017 - 5.45 pm CEST - STENTYS (FR0010949404 - STNT), a medical technology company commercializing the Xposition S Sirolimus-eluting self-apposing coronary stent, today reports its quarterly revenues and cash position at June 30, 2017.

* Unaudited data

STENTYS recorded revenues of €3.5 million over the first half of 2017, down 2.6% compared to the same period of 2016. This decline is linked to a negative base effect on the second quarter activity (-19.8%), associated with a €426k call for tender of MiStent stents won in the Middle East in June 2016. Excluding the impact of this sale, the second quarter revenues were up 0.2%.

Over the first six months of the year, Xposition S sales were up 20% in volume and 10% in value, compared to the first half of 2016.

At June 30, 2017, STENTYS had a cash position of €10.3 million, versus €12.4 million at March 31, 2017. This cash burn is in line with the plan to reduce the Company's expenditures.

Within the restructuring of its sales department, whose new organization is now in place, STENTYS has recruited Mr. Olivier Pierron as European Sales Director to especially oversee the direct sales force. He has over 20 years' experience in the launch, commercialization and development of innovative medical implants. He was previously Sales & Marketing Director EMEA for Surgery at ConMed (a global medical technology company specialized in the surgical sector).

Christophe Lottin, Chief Executive Officer of STENTYS, comments: "The increase in sales of our flagship product, Xposition S, confirms the growing demand for our self-apposing technology, which is particularly well-suited for the treatment of specific coronary lesions. Moreover, in recent months we have entirely reorganized our commercial structure and are delighted to welcome Olivier, our new European Sales Director, who will coordinate all our sales teams and implement our new commercial strategy."
