JDC Group AG has successfully placed a new senior secured floating rate bond with an initial volume of EUR 70 million, as announced on August 18, 2025. The bond, issued under Norwegian law, bears interest at a rate equal to EURIBOR (three months) plus a margin of 4.5% p.a. and has a term of four years. The bond is secured by the pledge of shares in significant Group companies and the assignment of intra-group loans. The issue was significantly oversubscribed, with Pareto Securities AS, Frankfurt Branch, acting as the sole manager for the placement. The net proceeds from the bond issue will be used to finance the acquisition of 60% of the shares in FMK Compare GmbH and HVG Hanse GmbH by Jung, DMS & Cie. AG, a wholly owned subsidiary of JDC Group AG [1].
