Fonterra's FY26 was a rebound for its investors. Per kilogram of milk, it was not one for its farmers.

On 24 September Fonterra reported profit after tax of $2.6 billion for the year to July, up 142%, and the result travelled as a rebound.

For the farmers who supply and own the co-operative, the recurring return per kilogram of milk fell.

That is not a contradiction in the accounts. A co-operative owes two things at once: a milk price to the farmers who supply it, and earnings to shareholders, including outside investors who supply no milk. The headline measures only the second.

We wanted to know how that dual obligation changes what an earnings rebound means. So we went past the results release to the documents behind it: the Annual Report, the Milk Price Statement, the co-operative's Constitution and the Commerce Commission's reviews of the milk-price calculation. We read the result once through an investor's measures and once through a farmer's, on matched bases, and checked each figure on the page it came from.

Through an investor's measures, FY26 was strong: reported profit after tax up 142%, and underlying earnings per share up 31% on a matched basis, from 54 cents to 71. Through a farmer's, it was slightly weaker than FY25. The milk price fell 4.6%, to $9.69 per kilogram of milk solids, and total payout per kilogram, the milk price plus the dividend, fell 2.9%, from $10.73 to $10.42. Alongside that sat a one-off $2.00-per-share capital return from the sale of Mainland Group. The direction of the signal differed, not just its size.

The reason is built in. The milk price is not simply what Fonterra decides to pay. It is calculated for a notional processor that turns all milk into five commodity products and earns a normal return on its capital, set at 5.6% after tax for this season. The regulator calls the notional figures “a benchmark to beat”. Fonterra's earnings therefore measure, in large part, how far its real business beat that benchmark. Its underlying return on capital was 14.2%, the highest since its formation. The two percentages are not on the same definition, so we do not subtract one from the other.

The disclosure holds up

Fonterra's Annual Report reconciles all seven earnings bases it publishes, states how cash reached shareholders, and shows gearing of 20.8% against its own policy target of 30–40%. The regulator found this season's milk-price calculation consistent with the statute. A reader with the Annual Report can separate the recurring from the one-off. The difficulty is in the results release, which uses the same “71 cents” on two different bases a year apart.

Two things surprised us

Our view, for what it is worth

A co-operative's headline result is two results, and in the same year they can point in opposite directions. Neither reading is wrong. The risk lies in treating either as the whole story, and in stripping out a one-off with a single “benefit” figure when it reached holders by three routes: a capital return, a gain excluded from normalised earnings, and a special dividend. Before drawing a conclusion from a co-operative's result, a board, lender or adviser could ask:

These are questions, not advice. The study makes no recommendation about Fonterra, its units or its milk price, and the decision stays with whoever holds it. It covers one co-operative in one year, from the public record. How farmers' shareholdings are spread, which would show how differently individual farmers read the same result, is not published.

If the public record misses something you know, we would like to hear it.
