IN Brief:
- Peugeot Invest and Continental Grain are set to become minority shareholders in Mérieux NutriSciences.
- Their investment will support financing for the agreed acquisition of Certified Group and its 31 North American laboratories.
- Certified adds microbiology, chemistry, certification, audit, research, and regulatory services across food and adjacent sectors.
Mérieux NutriSciences is bringing Peugeot Invest and Continental Grain Company into its shareholder base as minority investors, adding financial backing for the planned acquisition of Certified Group and its 31 laboratories across North America.
The new investments remain subject to customary regulatory approvals. Peugeot Invest and Continental Grain, also known as Conti, will join long-term shareholders led by majority owner Institut Mérieux and are expected to gain representation on the Mérieux NutriSciences board once the Certified transaction closes.
Mérieux announced its agreement to acquire Certified Group in August. The target generates approximately $300 million in annual revenue and provides microbiology and chemistry testing, contract research, certification and audit services, and regulatory consulting from a network of 31 laboratories.
The Certified transaction is expected to close during the final quarter of 2026 once customary conditions have been satisfied. Mérieux estimates the outsourced North American food testing, inspection, and certification market at more than $2.5 billion, giving the acquisition a substantial role in its regional expansion plans.
Certified’s operations cover core food sectors including animal protein, dairy, and packaged foods, alongside adjacent markets such as supplements, cosmetics, and over-the-counter products. Mérieux currently operates more than 140 accredited laboratories worldwide and employs more than 10,000 people.
The combined network will increase laboratory density in North America as well as overall testing capacity. Location is an important part of laboratory performance because many food-testing workflows begin with physical samples that have to be collected, transported, logged, prepared, analysed, and reported within a useful production timeframe.
Microbiology can be particularly sensitive to turnaround time. Food plants may hold raw materials, work in progress, or finished products while results are pending, and delays can increase storage requirements or postpone release to customers. A larger laboratory network can provide more options for routing samples and balancing workload when individual sites are operating near capacity.
Network size alone does not guarantee faster results. Methods, accreditation scopes, information systems, sample-handling procedures, and reporting formats have to remain consistent across facilities if work is to move between laboratories without adding uncertainty. The integration of Certified will therefore involve operating systems as well as ownership.
Laboratory consolidation can also affect where specialist equipment is located. Routine microbiological or chemistry testing may be distributed across many sites, while more complex analyses can be concentrated in laboratories with particular instrumentation or expertise. A wider network allows samples to be routed according to capability, but transport time and chain-of-custody controls have to be built into that model.
Mérieux has said the acquisition will support further investment in advanced testing technologies. Additional capital can be directed towards high-throughput analytical equipment, molecular methods, automation, and digital reporting systems, although any new method used for regulatory or customer decisions still requires appropriate validation and quality controls.
Food manufacturers increasingly rely on external laboratories for more than routine finished-product testing. Environmental monitoring, allergen verification, authenticity, contaminants, nutrition, shelf life, supplier assurance, and investigation work can all be outsourced, creating a more continuous relationship between laboratories and production sites.
That relationship becomes particularly important during an incident. A positive environmental result, undeclared allergen concern, or contaminant finding can trigger additional sampling across ingredients, equipment, and finished stock. Laboratory capacity has to expand quickly enough to support the investigation without creating a backlog that leaves large volumes of product on hold.
The Certified acquisition also adds research, audit, certification, and regulatory services alongside analytical testing. Combining those activities can give customers access to a wider range of technical services through one group, although laboratories and audit functions still have to maintain the independence and accreditation requirements applicable to individual services.
The incoming shareholders are joining before the acquisition has closed, so their immediate role is financial and governance support rather than operational integration. Their investment is intended to help finance the transaction and Mérieux’s wider expansion programme, with board participation due after completion.
Certified therefore represents both a scale increase and an integration project. Thirty-one additional laboratories add geographic reach quickly, but each facility brings staff, methods, equipment, accreditations, information systems, and existing customer commitments that have to be incorporated without disrupting turnaround or service continuity.
If the transaction closes as expected in the fourth quarter, the enlarged group will enter 2027 with a substantially larger North American testing footprint. Peugeot Invest and Continental Grain will join the shareholder base at the same time, giving Mérieux additional backing as it moves from acquisition financing into laboratory integration and capacity deployment.
