Sabesp Profit Falls 31% to R$1.46 Billion as Debt Costs Climb

Brazil · Business

The bigger story sits in the accounts below the operating line. Where the cost of borrowing to expand the water and sewer network turned a solid quarter into a smaller profit.

Sabesp, the newly privatised water and sanitation company that serves most of São Paulo state. Reported a second-quarter 2026 net profit of R$1.46 billion (about US$271 million).

That is 31.4% below the R$2.14 billion it earned a year earlier. As the cost of financing a heavy investment push ate into the bottom line.

What Sabesp reported

Sabesp reported reported net income of R$1.46 billion, about US$271 million, for the second quarter of 2026. A year earlier the company earned R$2.14 billion, about US$396 million, so the profit is down 31.4%.

Revenue and operations held up well; the decline came from the financing side of the accounts, not the taps.

Why the profit fell

The plants kept running well, and the drop was driven mostly by the company’s financial result. That financial line swung to a negative R$1.02 billion, about US$188 million, from a small positive figure a year earlier.

In plain terms, the interest on Sabesp’s growing debt swallowed a large slice of what the business earned.

The investment push behind the debt

Since it was privatised, Sabesp has committed to spend heavily to widen and modernise its water and sewer network. Building treatment plants and laying pipes costs money up front, and much of that is being funded by borrowing.

The extra debt lifts the interest bill now, in the hope of steadier, cleaner service and stronger cash flows later.

Reported versus adjusted profit

The company also reports an adjusted profit, which strips out one-off items to show the underlying trend. On that basis, adjusted net income was R$1.15 billion, about US$213 million, down a steeper 41.2% from a year earlier.

The two figures differ because the reported number includes gains and charges that do not recur every quarter.

The operating picture

Net revenue for the quarter came in at R$10.2 billion, about US$1.89 billion, broadly steady with a year earlier. Adjusted EBITDA, a rough gauge of cash profit from operations, was R$3.5 billion, about US$649 million.

That points to an EBITDA margin near 58%, healthy for a utility, though below the roughly 64% of a year earlier.

What EBITDA leaves out

EBITDA measures profit before interest, tax and the wear on assets, so it flatters a company that borrows a lot. For Sabesp this quarter, the gap between a solid EBITDA and a thinner profit is exactly that interest bill.

It is a useful reminder that a strong operating line does not always survive the trip down to net income.

What Sabesp does

Sabesp, short for Companhia de Saneamento Básico do Estado de São Paulo, is Latin America’s largest water utility. It supplies drinking water and collects and treats sewage for hundreds of municipalities across São Paulo state.

It serves tens of millions of people, which makes its spending and its bills a matter of daily life for the region.

Life after privatisation

The São Paulo government sold down its control of Sabesp in 2024, bringing in a private reference shareholder. The deal came with binding targets to reach universal water and sewer coverage years ahead of the old timetable.

Meeting those targets is what drives the investment, and the investment is what is reshaping the company’s finances.

What it means for customers

For households, the near-term trade-off is real: more spending on the network, funded in part through tariffs and debt. The promise is fewer outages, cleaner rivers and water reaching homes that never had a reliable connection.

A recent review trimmed some bills, but the long arc of privatisation ties charges to how fast the network expands.

What to watch next

Two things will shape the coming quarters: the pace of investment and the cost of the debt that funds it. If interest rates ease and the new assets start earning, the drag on profit should gradually fade.

Until then, expect the operating business to stay strong while the financing line keeps a lid on the bottom line.
