cyan AG: IPO issue price set at EUR 23.00 per share

Munich, March 23, 2018 – cyan AG, a European provider of intelligent, white labeled IT security solutions for mobile and fixed line network operators, internet services, and the financial sector, as well as their respective end customers, has set the issue price for its IPO at EUR 23.00 per share. The price is thus at the upper end of the previously announced range of EUR20.00 to EUR23.00 per share. At the set placement price, the cyan AG IPO was 2.7 times subscribed.

In all, the cyan AG flotation comprises a placement of 1,200,000 shares from a capital increase, plus an additional allocation (“greenshoe option”) of a further 180,000 shares to be created from an as yet still to be exercised capital increase from the company’s approved capital. All 1,380,000 of the shares offered to investors have been placed. The total placement volume, inclusive of the greenshoe option, thus amounts to some EUR 31.7 million.

The proceeds from the IPO will primarily serve to finance the full acquisition of Cyan Security Group GmbH, which acts as a holding for the operational units of the cyan Group, and in which cyan AG currently owns a stake of 51 per cent.

Additionally, the proceeds from the share offering shall also be used to realize organic and external growth potentials designed to strengthen the competitive position of cyan AG in the European market.

Trading in cyan AG shares is expected to commence on the Frankfurt Stock Exchange’s Scale segment on March 28, 2018. Shares have been assigned ISIN DE000A2E4SV8 and German securities identification code (WKN) A2E4SV.
