Holcim is owned by public shareholders on the Swiss stock exchange, with no single controlling owner, though longtime investor Thomas Schmidheiny remains the largest individual shareholder.
Holcim has grown from a small Swiss cement company into one of the very largest building materials producers in the world, supplying cement, aggregates, and ready mix concrete across dozens of countries.
The company traces its roots back to 1912 in Switzerland, and the Schmidheiny family played a defining role in its growth for much of the twentieth century.
So who actually controls a company this large, and what changed after Holcim spun off its entire North American business in 2025?
This guide will explore who owns Holcim today, who its largest shareholders are, what the Amrize spinoff means for the company, and how Holcim compares to other major building materials producers.
So let’s get started.

Who Owns Holcim in 2026
Holcim is a publicly traded company listed on the SIX Swiss Exchange, meaning ownership is spread across public shareholders rather than held by one controlling entity.
Thomas Schmidheiny remains the largest individual shareholder, holding roughly 5.7 percent of the company as of the most recent share register.
The Schmidheiny Family History
Holcim traces its roots back to 1912, when the company began as a small Swiss cement producer that would eventually grow into a global operation.
The Schmidheiny family guided much of that early growth, and Thomas Schmidheiny in particular played a central leadership role for decades before stepping back from day to day management.
Today the family retains meaningful influence through its remaining share position, even though it no longer controls the company outright.
Who Are the Largest Institutional Shareholders
UBS Fund Management Switzerland holds roughly 5.6 percent of Holcim shares, making it one of the very largest institutional holders alongside Thomas Schmidheiny himself.
BlackRock holds close to 5.2 percent, while Martin and Rosmarie Ebner hold about 3.0 percent, rounding out the list of shareholders with a stake of 3 percent or more.
What the Amrize Spinoff Changed
In June 2025, Holcim completed a full spinoff of its entire North American business, creating a brand new independent company called Amrize.
Shareholders received one Amrize share for every Holcim share they already owned, splitting the combined business into two separately traded companies, as confirmed by MarketScreener.
Holcim vs Other Global Cement Producers
Holcim now competes far more directly with companies like Cemex outside North America, since its own former US and Canadian operations now belong to the separate Amrize company.
Both Holcim and Cemex remain publicly traded with broad institutional ownership, standing in contrast to family owned regional producers such as SRM Concrete.
Smaller regional operators like Ernst Concrete also compete for local contracts, though they operate at a much smaller scale than a global producer like Holcim.
Is Holcim Good Quality?
Holcim has built a strong global reputation for cement and building materials, supplying products used in major infrastructure projects on nearly every continent.
The company has also invested heavily in lower carbon cement technology, positioning itself as a leader in sustainable construction materials among large global producers.
