H&R GmbH & Co. KGaA resolves to prepare for the transition from the regulated market (Prime Standard) to the Scale segment of the Frankfurt Stock Exchange

• Plans to revoke listings on the regulated markets of the stock exchanges in Düsseldorf, Frankfurt am Main, and Hamburg

Salzbergen, Germany, June 25, 2026. The management of H&R GmbH & Co. KGaA (H&R KGaA for short; DE000A2E4T77) today resolved to prepare for the transfer of the company’s stock listing from the regulated market (Prime Standard) of the Frankfurt Stock Exchange to the Scale open market segment of the Frankfurt Stock Exchange and to submit the necessary applications. In this context, the company also intends to submit corresponding delisting applications to the Düsseldorf and Hamburg stock exchanges, where H&R shares are also listed on the regulated market.

By moving to the Scale segment, the company aims to reduce the regulatory and administrative burden associated with a listing on the regulated market. At the same time, its presence on the capital market will continue to be ensured through the Frankfurt Stock Exchange. H&R KGaA considers the fact that, given the company’s size and capital market orientation, the Scale segment appears to be more suitable. Scale is a segment of the Open Market of the Frankfurt Stock Exchange that is aimed in particular at growth companies as well as small and medium-sized enterprises (SMEs).

Management intends to apply to the Frankfurt Stock Exchange to revoke the shares’ admission to the regulated market and, in parallel, to have the shares included in the Scale segment, subject to the fulfillment of all relevant listing requirements.

Based on the legal changes introduced by the Location Promotion Act (“Act to promote private investment and Germany as a financial center”; StoFöG), significant portions of which took effect on February 10, 2026, this transition from the regulated market to the Scale segment of the Frankfurt Stock Exchange is permissible without an accompanying delisting tender offer.

The company will keep the capital market informed of the further course of the proceedings in accordance with legal requirements.
