Water cooler M&A: what a buyer checks before they pay up for your book

A private equity buyer is closing in on about half of Nestlé's European water business at a valuation near €5bn. That deal puts a public price on bottled brands. But the thing financial buyers really like is duller. It is the water cooler book that bills the same customers every month. A private equity buyer just put a roughly €5bn price on branded water, and the recurring cooler book is what financial buyers want next. If you own a water dispense operator, one question matters. What will a buyer pay for, and what will they mark down?

The buyer is not buying your machines

Two operators with the same number of machines can sell for very different prices. One runs a clean, sticky book of business accounts. The other runs a churny book of cheap homes and one-off sites. Same unit count. Very different value.

The buyer wants the income those machines will still produce in three years. The steel and plastic count for little on their own. BWD means bottled water dispense, the coolers fed by 15 or 19 litre bottles. POU means point of use, coolers plumbed into the mains. ITS means instant taps, the counter units that pour boiling, chilled and sparkling water. A buyer prices each one differently, because each churns and earns at a different rate.

Three numbers that move the price

Three numbers move the price more than fleet size: churn, revenue per machine, and the mix of bottled, mains-fed and tap units.

Churn comes first. It tells the buyer how much of today's income is still here next year. In the biggest, cheapest markets, bottled cooler churn runs into double digits, and every lost account is income the buyer discounts. In our own market database, the highest-volume markets often show the weakest retention. Big fleet, leaky book.

Revenue per machine comes next. A serviced business account with a sparkling tap earns far more than a cheap home cooler. Across Europe, value is now growing faster than the number of machines. That gap is the whole story. Smart operators prune the cheap accounts and keep the ones that pay.

Mix comes third. Bottled coolers still do real work in factories, on building sites, and in places with no mains. They stay a strong revenue line. But a book that is almost all bottled, in a market moving to taps, carries more risk than one that has already shifted.

What a clean data room looks like

A clean data room shows retention by contract type, revenue per machine by account, and proof your filters meet the new water rules. From January 2026, EU rules set hard limits for PFAS, the so-called forever chemicals, in drinking water. From August 2026, PFAS is also banned from food-contact packaging above set limits. A buyer will ask if your filters and bottles already meet these limits. "We think so" is not an answer that holds a price.

Most value is lost in the gaps a buyer finds when the numbers do not add up. Missing contract dates. No split of owned versus serviced accounts. Usage data you cannot pull per account. Each gap is a reason to pay less.

Get the book ready before you sell

Start building the file a year before you sell, because you cannot fix a churn number in the week before diligence. Retention takes months to bend. Contract data takes weeks to clean. Filter proof takes a supplier chase. The operators who get paid the most can prove the income is boring and repeatable. With a financial buyer now setting the price for water, that proof is worth real money.
