  • Kemira announced plans to acquire SIDRA Wasserchemie on February 11, 2026.
  • Germany’s Federal Cartel Office approved the deal on September 18, 2026.
  • The planned acquisition price was approximately EUR 75 million.

Kemira Oyj’s planned acquisition of SIDRA Wasserchemie GmbH, a German coagulant producer, received approval from Germany’s Federal Cartel Office following a regulatory review process.

The acquisition, first announced by Kemira on February 11, 2026, was subject to clearance by competition authorities in Germany. SIDRA Wasserchemie, a family-owned business, operates two production sites in Germany and supplies customers in Germany, Belgium, and the Netherlands.

The Federal Cartel Office granted approval for the transaction on September 18, 2026, after conducting an in-depth antitrust review. The regulator stated that although the merger would create a strong market position for iron salts in certain regions, sufficient competitors would remain both domestically and in neighboring countries.

Kemira’s investor presentation on February 12, 2026, described the acquisition as planned and pending competition authority approval at that time. The company’s acquisitions and divestments record also lists the acquisition as occurring on February 11, 2026.

What the numbers show

  • SIDRA Wasserchemie reported revenue of approximately EUR 40 million in 2024.
  • SIDRA Wasserchemie’s EBITDA for 2024 was around EUR 10 million.
  • More than 60 SIDRA Wasserchemie employees were expected to join Kemira after closing.

The planned purchase price for the acquisition was approximately EUR 75 million, subject to customary adjustments. SIDRA Wasserchemie’s financial performance in 2024 included revenue of about EUR 40 million and EBITDA of roughly EUR 10 million.

The Federal Cartel Office noted that the merger would result in a strong market presence for iron salts in parts of Germany and nearby countries. However, the regulator stated that transport costs and the availability of other suppliers would limit the merged entity’s market power.

Upon completion of the acquisition, more than 60 employees from SIDRA Wasserchemie were expected to become part of Kemira. The integration would expand Kemira’s presence in the water treatment chemicals sector in the region.

Kemira’s announcement and regulatory filings confirm that the acquisition process followed the required competition review steps, with approval granted after the authority’s assessment of market conditions and competitive landscape.
