A $721m Water Purifier Deal Closed Higher Than It Signed. The Water Cooler Market Should Ask Why
By Zenith Water Dispense Team ·
Carlyle signed for Chungho Nais in June at about $644 million and closed in August at $721 million. The company's operating profit had already fallen by a third. The share register changed. The trading did not. For a water dispense market full of family-owned books heading into succession, that gap is the number to study.
If this were my business, I would spend a month on the share register. The sales deck could wait. Carlyle finished buying Chungho Nais on 26 August for $721 million. In June the reported price was more than one trillion won, about $644 million.
Nothing about the trading improved in between. The company's 2025 operating profit had already fallen 32.4%, to 45.3 billion won. The extra money did not buy a better business. It bought a clean share register.
What actually moved between June and August
Chungho Nais is South Korea's fifth largest water purifier maker. It was founded in 1993 and was once the number two. Its 2025 sales rose 6.5% to 503.4 billion won. Operating profit fell to 45.3 billion won, about $31 million.
Its rivals had a better year. Coway lifted operating profit 10.5% over the same period. Cuckoo Homesys was close to flat. Chungho went into the sale as the weakest of the three on profit.
The founder died suddenly in June 2025. The family put the company up for sale to cover an inheritance tax bill. Estimates put that bill at 200 to 300 billion won. A son from an earlier marriage then sued to overturn the will. He also filed a claim for a share of the estate.
At close, that heir agreed to sell his inherited stake on identical terms. Carlyle ended up owning 100%. The gap between the June figure and the August figure is mostly the price of certainty.
Who can sign is worth more than last year's profit
A purifier rental book is an annuity. Customers pay every month, and contracts renew whether or not last year was strong. Buyers of these books price the account base first and the income statement second.
Carlyle's offer was already rich on the numbers. Reported terms in the spring put the earnings multiple more than 30% above Coway's. It was more than double Cuckoo Homesys. That was for the number five player with falling profit.
An annuity with a contested owner is worth far less than the same annuity with one seller. Every unresolved claim on the shares is a discount, or a reason to walk. Culligan looked at this same company in 2022 and walked away over price and union opposition.
Most of European dispense has the same problem coming
Zenith tracks 31 European markets plus the United States and five markets beyond it. The figures come from direct operator interviews and local data partnerships. Below the top few operators in almost every market sits a long tail of family-owned businesses.
Many were started in the 1980s and 1990s. Those founders are now at or past retirement age. The most common reason a good European dispense book stalls in a sale is a messy share register.
Old wills, silent partners, verbal option promises and dormant minority holdings all surface at the worst moment. They surface during exclusivity, when the buyer holds all the cards.
The field team can stop a deal as well
Chungho's unions objected to this sale too. They said the process was pushed forward without consulting them. The same opposition helped end the 2022 approach.
This carries more weight in dispense than in most industries. The driver and the technician hold the customer relationship. Head office does not. A buyer who has met only the finance team has met the wrong half of the business.
Bottled books carry the same annuity
None of this is only a point of use story. Point of use, or POU, means a mains-fed cooler plumbed straight into the water supply. A bottled round is an annuity too, and it carries something a purifier book does not.
The delivery route itself is hard to copy. Route density takes years to build and cannot be assembled in a spreadsheet. Bottled dispense is still growing in parts of Europe. Spain passed a million units in 2025 on a thirteenth straight year of growth. Western European bottled placements rose 3.4% last year.
Buyers pay for the annuity and the route that serves it, whatever comes out of the tap.
What I would do before the year ends
If you might sell inside five years, fix the register now. Find every share and every promise made along the way. Track down anyone who could claim a piece of the company.
Do it while nobody is watching and you still have time. If you are buying, ask who can sign before you ask what it earns. A 12% swing on a $644 million deal is what unresolved ownership costs. That was a case that ended well.
