Mayr‑Melnhof Karton Expands German Footprint by Acquiring R.D.M. Arnsberg Recycling Plant

Mayr‑Melnhof Karton AG Strengthens German Presence with Acquisition of R.D.M. Arnsberg Operations

Mayr‑Melnhof Karton AG (MMK) announced that its subsidiary MM Board & Paper has signed an agreement to acquire the operating business of the recycling carton plant R.D.M. Arnsberg in Germany. The transaction is structured as an asset deal and is scheduled to close in the fourth quarter of 2026.

Key Details of the Acquisition

The acquisition represents a strategic investment in MMK’s core business of manufacturing cardboard, folding cartons, and packaging materials from recycled waste paper. By integrating the Arnsberg plant into its established German production network—which already includes several cartonboard mills—MMK will reinforce its capacity to supply high‑quality liner products and expand its market share in the European packaging sector.

Market Context

The transaction was reported on 17 August 2026, the same day the Vienna Stock Exchange closed slightly lower, with the ATX index down 0.47 percent at 6 701,69 points. European equity markets, including the DAX and Euro‑Stoxx 50, remained near recent all‑time highs despite broader geopolitical uncertainties. Oil prices edged upward modestly, and market sentiment was influenced by expectations of stable rather than rising U.S. interest rates following weaker‑than‑expected economic data.

Financial Position of Mayr‑Melnhof Karton AG

MMK’s focus on recycled raw materials aligns with global sustainability trends and supports its long‑term growth prospects. The addition of the Arnsberg plant is expected to enhance operational synergies, improve economies of scale, and solidify the company’s position as a leading supplier of high‑performance packaging solutions in Europe.
