AMG Critical Materials N.V. Announces Sale of Graphit Kropfmühl GmbH to Asbury Carbons

Amsterdam, 10 October 2025 (Regulated Information) --- AMG Critical Materials N.V. (“AMG”, EURONEXT AMSTERDAM: “AMG”) and Asbury Carbons Inc. (“Asbury Carbons”) are pleased to announce the signing of a definitive agreement for AMG to sell Graphit Kropfmühl GmbH (“GK”) to Asbury Carbons, a portfolio company of Mill Rock Capital. The transaction reflects an enterprise value of $65 million.

GK operates its own graphite mine at its headquarters in Kropfmühl, Germany, and holds a majority stake in a graphite mine in Sri Lanka. Asbury Carbons will assume all GK operations, including approximately 350 employees. For the twelve months ended August 2025, GK generated $65 million in revenue.

With this transaction, AMG completes its exit from the natural graphite business.

“The sale of GK highlights AMG’s commitment to proactive portfolio management,” said Dr. Heinz Schimmelbusch, CEO and Chairman of the Management Board of AMG Critical Materials. “Natural graphite remains an attractive business, but we have not been able to establish GK as a leading supplier to the battery anode market. We are confident that GK will find greater opportunities as part of Asbury Carbons’ graphite portfolio. Meanwhile, AMG will use the proceeds from this transaction to strengthen its balance sheet and focus on its core growth businesses.”

This transaction follows AMG’s repurchase of the remaining 40% interest in GK from Alterna Capital Partners on March 12, 2025. The terms of that transaction remain unchanged: the purchase price may be settled by AMG in cash at the end of a three-year period or in AMG shares at any time within those three years, at AMG’s discretion.

Headquartered in Asbury, New Jersey, Asbury Carbons is a global leader in carbon-based solutions serving industrial markets, employing more than 300 people across 10 production facilities in North America and Europe.

“This combination unites two market leaders in carbon solutions, together representing more than 250 years of history and expertise in the industry,” said Gregg Jones, CEO and Chairman of the Board of Asbury Carbons. “We look forward to expanding our service, strengthening supply chain security and delivering new technologies and solutions to our customers worldwide.”

The transaction is subject to customary regulatory approvals, and AMG and Asbury Carbons expect the sale to close by year-end 2025.
