Dairy Due Diligence

Why Independent Due Diligence Matters in Dairy

Due diligence is about risk. Before you commit, the job is to find what is already wrong or waiting to go wrong — a food safety failure, a lost anchor customer, an undisclosed compliance gap, an over-stated capacity claim — that would destroy shareholder value, damage the brand, and expose directors to personal liability. These risks are the same whether the plant is brand new or a hundred years old. Miss them at the deal stage and the financial model never recovers.

In dairy — and above all in infant formula — due diligence is not a box-ticking exercise. It is confirmation that everything is being done correctly, because when it is not, lives and livelihoods are at stake. A single food safety failure can end a company. Sanlu, once one of China’s largest dairy producers, was bankrupt within months of the 2008 melamine contamination that harmed an estimated 300,000 infants and killed six. In 2022, Cronobacter contamination at Abbott’s Sturgis plant in the United States triggered a recall, a plant shutdown, a national formula shortage and a Department of Justice investigation. In both cases the warning signs were there to be found beforehand. That is what due diligence is for.

Generalist due diligence providers can read accounts and benchmark KPIs. What they often cannot do is walk a plant, look at a falling-film evaporator and judge its true remaining life, assess whether a CIP regime will actually hold microbiological control, or read a yield log and separate recoverable losses from structural ones — the operational realities that determine whether a plant is safe, compliant and sustainable under new ownership. That is the gap we fill.

What We Assess

Plant Condition and Capex Realism

The largest unwelcome surprises after a dairy acquisition typically come from one of two places: capex that was deferred under previous ownership and is now coming due, or capex required to deliver the business plan that the seller did not quantify. Both are diagnosable with proper technical due diligence at the deal stage.

What we assess on the plant

• Critical equipment condition — evaporators, spray dryers, separators, pasteurisers, cheese vats, fermentation tanks, packaging lines — with realistic remaining life estimates
• Deferred maintenance — what should have been spent and was not, and what that means for capex in years 1 to 3
• Compliance and regulatory headroom — can the plant pass a customer audit today, can it support new product categories the business plan requires, will it meet impending regulatory changes
• Capacity headroom — is the stated capacity real, what is the actual bottleneck, what does it cost to unlock the next tier of throughput
• Hidden expansion constraints — effluent treatment, utilities, site, planning — that limit the headline expansion potential the seller is presenting

How We Engage

Independence as the Value Proposition

The reason we are paid is independence. We are not a contractor angling for the post-deal capex work, not an equipment supplier hoping for an order, not a strategic adviser whose fees continue if the deal proceeds. The opinion is the same whether the deal goes ahead or not, and we will tell you when not to do a deal as clearly as when to proceed.

That independence is also the reason we do not take success fees, commissions or deal-contingent arrangements. The technical view has to be the same on a buy-side mandate where the fund wants to do the deal and on a vendor mandate where the seller wants to maximise price. Same data, same analysis, same conclusion.

Frequently Asked Questions

What does dairy due diligence cover?

Independent technical and commercial assessment of a dairy target - plant condition, equipment life, capex required, yield and operational efficiency vs sector benchmarks, supply chain risk, customer concentration, management quality and an explicit view on whether the seller's business plan is achievable. Output is a board-ready report with quantified risks, opportunities and a clear independent recommendation.

Who do you do due diligence for?

Private equity funds, family offices, strategic trade buyers, lenders doing technical credit assessment, sellers preparing vendor due diligence packs, and management teams considering MBOs or capital raises. Independent of all equipment suppliers and dairy operators - the advice is yours, not the deal's.

How long does dairy due diligence take?

A focused review on a single-site target is typically 2 to 4 weeks including site visit and report. A full multi-site dairy business review is typically 4 to 8 weeks. Compressed timelines for competitive bid situations are possible with appropriate scoping.

Do you cover greenfield projects as well as acquisitions?

Yes. For greenfield projects we assess technical design, capex realism, operating economics, supply chain feasibility and market positioning before significant capital is committed. For expansion projects within existing operations we evaluate whether the proposed investment will deliver the projected returns and whether less expensive alternatives have been properly considered.

What is your fee model?

Day rate plus expenses, agreed upfront against a scoped brief. No success fees, no commission, no deal-contingent arrangements. We are paid for independent technical and commercial opinion - the value is independence, and that requires the same view whether the deal proceeds or not.

Will the seller object to a tough finding?

Sellers and their advisers are used to thorough technical and commercial due diligence on dairy assets. Findings are factual, evidenced and quantified. Where the technical view differs from the seller's narrative, our job is to give the buyer the truthful picture - politely, but clearly.
