CMA accepts fast-track remedy in chemicals deal

The CMA has accepted a remedy from Sika and MBCC preventing their global merger from harming the UK construction industry.

Early in the Phase 2 investigation, the 2 businesses accepted that Sika’s anticipated purchase of MBCC raised competition concerns in the supply of chemical admixtures in the UK. The parties asked the Competition and Markets Authority (CMA) to “fast-track” the case to the assessment of a remedy that could address those concerns, meaning that the case could be resolved more quickly. As a result, the CMA has today published its final decision, with a detailed assessment of a complex remedy, well ahead of the deadline of 24 January 2023.

The merging businesses proposed to sell MBCC’s chemical admixtures business in the UK, across Europe and several other countries, including its central research and development assets. The CMA assessed whether the parties’ proposed remedy would fully restore the competition that would be lost as a result of the merger. Following a detailed review of the remedy, and consultation with stakeholders and various modifications proposed by Sika and MBCC, the CMA has accepted that the proposed sale would resolve the competition concerns it identified, bringing the case to a close.

The CMA has engaged closely and constructively with other agencies reviewing this transaction throughout its investigation, including regarding the effectiveness of the proposed remedy.

Richard Feasey, Independent CMA Panel Chair, said:

After Sika and MBCC accepted early on that the deal would have caused competition concerns in the UK construction industry, we were able to focus our inquiry on their proposals to address our concerns. The proposals agreed today will maintain the level of innovation, services and quality in chemical admixtures available to concrete producers and help prevent this deal raising prices for the construction industry in the UK.

We are pleased that by working collaboratively with the companies and other competition authorities, we have been able to reach this decision on a complex global remedy so quickly. The CMA will keep looking for ways to make merger control focused, fast and efficient.

In November 2021, Swiss firm Sika agreed to buy the German based MBCC Group in a £4.5 billion deal. Sika and MBCC are the 2 largest UK suppliers of chemical admixtures, which are an essential input for products like concrete and cement used in the construction industry and control various characteristics of concrete, such as its strength or setting time.

The companies are widely regarded as the strongest suppliers in the UK market, particularly in relation to their product development and innovation capabilities, and together account for over half of the UK supply.

Following an initial Phase 1 investigation, the CMA identified competition concerns in the supply of chemical admixtures in the UK. As a result, the CMA referred the deal for an in-depth Phase 2 investigation in August 2022.
