Holcim stock gains new carbon-storage investment angle

Holcim announced on November 4 that it had invested in 44.01, a developer of carbon-mineralization technology. The company said the investment supports 44.01's international expansion and scale-up while extending an existing commercial relationship.

Holcim stock traded at 81.72 euros on Lang & Schwarz at 17:41 CET on Tuesday, November 10, 2026. That was 1.76% above the 80.31-euro quote in the latest relevant own report from November 9 at 12:08 CET. This comparison uses the prior report's Lang & Schwarz quote and is separate from any Xetra daily move.

Carbon storage moves toward scale

According to the Holcim media release, captured carbon dioxide is injected into naturally reactive ultramafic rock formations, where it mineralizes into stable carbonate rock.

Since July, Holcim and 44.01 have operated a pilot under live industrial conditions at Holcim's Fujairah cement plant in the United Arab Emirates. Holcim said the project is already storing captured carbon underground and converting it into solid rock.

Strategic relevance for investors

The investment adds a new technology angle to Holcim's portfolio of digital and decarbonization initiatives. Ram Muthu, Holcim's head of operational excellence, said the approach could support storage close to production where geological conditions are suitable and offshore storage is limited.

Holcim said the transaction forms part of its open innovation ecosystem and is the 22nd investment made through Holcim MAQER Ventures. The financial terms and ownership stake were not disclosed, leaving the immediate earnings effect impossible to quantify.

The broader Swiss market environment is covered in current SMI market reports.
