Kingspan, the Irish building materials manufacturer, has been penalised €40m (£33.9m) by the European Commission for supplying false and misleading information during a competition investigation into its attempted acquisition of a rival firm.
The company, headquartered in County Cavan and valued at approximately €18bn (£15.3bn), sought to acquire Trimo, a competitor in insulating panel manufacturing, in 2021. The proposed transaction triggered a mandatory review under European Union merger regulations to assess whether it would substantially diminish competition in the market.
During that investigation, the Commission determined that Kingspan had engaged in systematic non-compliance with its disclosure obligations. An initial assessment in March 2024 identified six potential breaches; after the company submitted its response and the Commission issued supplementary objections, the final decision established four substantiated infringements. Kingspan was fined €10m (£8.5m) for each breach.
According to Mirage News reporting on the Commission's decision, the four infringements were classified as serious and at least negligent, with the Commission concluding that Kingspan could not have been unaware of its legal obligations to disclose information accurately.
What information was withheld or misrepresented?
The Commission found that Kingspan falsely asserted that certain critical documents did not exist, mischaracterised factual matters, and claimed it was unable to supply essential information that only the company possessed. According to Europa Press coverage of the case, the disputed information concerned Kingspan's tracking of mineral-fibre panel penetration rates, bidding data, research and development programmes, and the involvement of board members in acquisition strategy and deal negotiations.
The Commission stated that Kingspan's conduct created obstructions during the merger review and prevented proper assessment of the transaction's competitive implications.
Why did the deal not proceed?
In 2022, Kingspan withdrew its bid for Trimo after the Commission signalled serious reservations about the merger's compatibility with EU competition law. The Commission's April 2021 in-depth review had raised serious doubts about whether the transaction would comply with the EU internal market and the European Economic Area framework. The watchdog's original concerns centred on the risk of price increases in the mineral-fibre sandwich panel market across multiple EU member states and the United Kingdom.
What did the Commission say about the violations?
Teresa Ribera, the European Commission's competition commissioner, stated:
When companies withhold or distort the truth, they undermine a system that protects fair competition for everyone. There can be no compromise on disclosure and transparency. If they fail to do so, we do and will act firmly.
The Commission emphasised that Kingspan's obstruction of the investigation undermined the integrity of the merger review process and the broader framework designed to protect competitive markets across Europe.

The fine represents a significant enforcement action by the Commission against corporate non-compliance during merger investigations, signalling its commitment to ensuring transparency and accuracy in the regulatory process.
