Kuros convenes Extraordinary General Meeting

Schlieren (Zurich), Switzerland, November 8, 2018 – Kuros Biosciences (SIX: KURN) (the Company) today announced that it will hold an Extraordinary General Meeting (EGM) of shareholders to seek approval to increase the Company’s ordinary share capital and to establish conditional capital. The EGM will be held at Kuros Biosciences AG, Wagistrasse 25, 8952 Schlieren, Switzerland on November 29, 2018 at 10.00am CET.

The share capital increase aims at raising approximately CHF 16 – 20 million to advance research, development and marketing of the Company’s key products. Specifically, the Company seeks approval from shareholders for an increase of the ordinary share capital of up to CHF 4.3 million for the issuance of up to an additional 4.3 million shares and to establish conditional capital of CHF 1.7 million for the issuance of up to 1.7 million shares.

The use of proceeds from a capital increase aims to enable the Company to advance the phase 2 clinical study of its proprietary fibrin-PTH (KUR-113) product in spinal fusion and to progress commercialization of MagnetOs bone graft substitute in the U.S. and selected geographies in Europe.

The phase 2 study of KUR-113 is scheduled to start enrolling patients in 2019 with an anticipated interim readout by the second half of 2020. The Company’s management is convinced that KUR-113 targets an important medical need in spinal fusion patients and represents a significant commercial opportunity.

Several large existing shareholders as well as new investors have indicated their interest in participating in a potential equity financing. The final terms of the financing will depend on, inter alia, the Company’s stock price at the time of pricing and announcement of the capital increase and the interest amongst existing and new equity investors. In light of the planned capital increase, the Company will abstain from further draw-downs of its Standby Equity Distribution Agreement.

Mirabaud and Octavian are acting as advisors to the Company.
