Brewer Science closes Heraeus Epurio chemicals deal on 3 August 2026, adding a Dayton, Ohio production site

Brewer Science completed its acquisition of the semiconductor chemicals business line of Heraeus Epurio on 3 August 2026, adding a production facility in Dayton, Ohio and sales and technical support teams across Asia to its existing US operations.^[1] Financial terms were not disclosed.

What transferred in the deal

The acquired business develops and manufactures a range of ultrapure specialty chemicals used at advanced process nodes. The product portfolio includes:

• Photoacid generators
• Photoinitiators
• Monomers
• Crosslinkers^[1]

These materials are manufactured to extremely low trace-metal tolerances, because even small impurities can affect yield and reliability at leading-edge nodes.^[1] Heraeus Epurio had been a recognised supplier of these chemistries to the semiconductor industry, and the Dayton site was its dedicated production facility for the business.

Vertical integration as the strategic rationale

Brewer Science frames the deal explicitly as a vertical integration move. By bringing formulation and manufacturing in-house, the company extends its company-wide Zero Defects standard further up its own supply chain - covering synthesis, formulation, and production under a single quality framework rather than relying on an external supplier for the underlying chemistries.^[1]

"Our customers' success is built on trust in both our materials quality and our supply chain integrity," said Dr. Sri Kommu, co-CEO of Brewer Science. "This acquisition enables the vertical integration necessary to reinforce our unified approach spanning synthesis, formulation, and production."^[1]

The acquired chemical portfolio complements Brewer Science's existing materials for advanced lithography, packaging, printed electronics, and smart devices.^[1] The company also gains more scope to develop the underlying chemistry for future chipmaking processes, rather than only supplying formulated materials downstream.

US manufacturing footprint after the deal

The Dayton facility is the third US production location for Brewer Science. The company is headquartered in Rolla, Missouri, where it was founded in 1981, and opened an innovation center in Chandler, Arizona in September 2025, focused on research and collaboration with semiconductor customers.^[1]

All of Brewer Science's R&D and manufacturing operations are conducted in the United States, a positioning the company has emphasised as supply-chain resilience has become a priority across the industry.

"Adding this ultrapure chemical line to our portfolio means we're not just meeting today's demands, we're anticipating what next-generation technology will require before our customers even know to ask for it," said Dan Brewer, co-CEO of Brewer Science.^[1]

The company operates as a certified employee-owned company and has eleven offices worldwide.

The deal adds a domestic source for specialty chemicals that are otherwise concentrated in a small number of suppliers globally. The question to watch is how quickly Brewer Science can qualify the Dayton output with customers at advanced nodes - qualification cycles for ultrapure process chemicals at leading fabs typically run several months to over a year, and that timeline will determine how soon the vertical integration translates into measurable supply-chain benefit for chipmakers.
