A share price tends to move through four phases: moving sideways (stage 1), rising (stage 2), stalling near a high (stage 3) and falling (stage 4). Today Companhia de Saneamento Básico do Estado de São Paulo - SABESP is in stage 1. The phase helps read everything below.

Over the last 10 years the share price moved +167% while the S&P 500 moved +261%, so it is behind the index over that whole period. It was last ahead over 13 weeks in the week of 23 October 2026. The chart above shows the 13-week comparison for every week.

This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP declared BRL 0.66 per local share for Dec 2025. It reports in Brazilian reais, and one US-listed share can stand for several local shares, so we do not set this against the dollar price or show a yield.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP earned BRL 1.4 B of net profit in the Jun 2026 quarter, −32.2% on the same quarter a year earlier. Full-year FY25 profit was BRL 8.5 B. Over 4 years profit has grown 38.4% a year on average. That is 14.2% of the quarter's revenue.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

The same quarter a year earlier earned BRL 2.1 B.

For the full year, FY25 profit was BRL 8.5 B (−11.7% on the year before).

Why profit moved: revenue changed +13.9% on a year earlier and the margin moved −5.7 percentage points. Sales did the work while the margin got thinner.

On average over the last four quarters, profit changed +2.0% and revenue +9.7%. Profit is growing slower than sales: rising costs are taking part of the growth.

This company reports in Brazilian reais, not US dollars, so the money charts are left out here. The figures in the text are in that currency (BRL); nothing is converted.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP reported BRL 10.2 B of revenue in the Jun 2026 quarter, +13.9% on the same quarter a year earlier. That is the 3rd quarter in a row with growth on the year before. Over 4 years it has grown 18.2% a year on average.

Revenue is everything the company billed its customers in the period.

The last full year, FY25, came in at BRL 38.1 B. The last four reported quarters add to BRL 40.9 B.

FY25 revenue was BRL 38.1 B, +5.4% on the year before.

Recent pace: the last four quarters grew +9.7% on average, against 18.2% a year over the longer run, so this year is growing slower than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew +1.6%, against +23.0% a year over the last 8 quarters (rolling over); profit over the last 12 months grew −28.0%, against +40.6% a year (rolling over).

Companhia de Saneamento Básico do Estado de São Paulo - SABESP's operating margin was 31.5% in the Jun 2026 quarter, 5.7 percentage points lower than the same quarter a year ago. Across 5 years it has been between 20.9% and 42.8%. The latest quarter is within that range.

Operating margin is what is left from every BRL 100 of sales after the costs of running the business, before interest and tax. It shows pricing power and cost control.

Why: the operating margin move is clear, but the cost details behind it are not in our data, so we show the move without guessing the reason.

Over the last 3 years, 96% of Companhia de Saneamento Básico do Estado de São Paulo - SABESP's reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in BRL 8.4 B of operating cash against BRL 8.5 B of profit.

The profit and loss account shows what was earned. The cash-flow statement shows the cash that actually came in. Comparing operating cash flow with profit is one of the best checks that a profit is real.

After BRL 13.7 B of spending on assets, free cash was −BRL 5.4 B: it spent more than its operations brought in.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason.

What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent BRL 21.9 B on assets over the last 3 years. Averaged over those years that is 19.2% of FY25 revenue a year.

Working capital is the cash tied up between paying suppliers and getting paid. Debtor days: how long customers take to pay. Inventory days: how long stock sits. The cash cycle: the whole loop, in days of sales.

Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn.

Spending on assets: BRL 21.9 B over the last 3 years.

In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP's P/E is 11.2×, with too little history to compare. This compares the share price with the company’s own past. It does not say what the business is worth.

P/E is the share price divided by a year's profit per share: how many dollars the market pays for each dollar of yearly profit.

In short: there is too little history to say whether the multiple is high or low for this company, so the earnings trend underneath matters more than the multiple.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP's business is giving mixed signals. There is no clear direction across the growth lines, with ROCE steady at 14.3%; each line tells part of the story. This is based on 12 quarters of 3 measures, with some gaps.

Every business is somewhere on a path of getting better or worse, and this section names where. The last 12 quarters of growth in revenue, profit and earnings per share, plus the return the business earns on its capital, are read as lines. Getting worse: the lines are falling. Turning around: a low point has just formed and the last few quarters are rising from it. Getting better: the rise from the low has lasted. Growing steadily: steady growth with healthy returns. Slowing from a peak: still high, but slowing. When the lines disagree the result is mixed; too little history means no reading. CAGR (compound annual growth rate) is the steady yearly rate that would turn the starting value into the latest one. It is the fairest way to compare growth over different periods. If the 1-year figure is much bigger than the 10-year one, recent growth is running faster than the long-run trend. A dash means there is no figure for that period, or the starting year was a loss, where a growth rate means nothing.

Why it matters: when the lines disagree, each line above matters more than any single label.

This reading has some gaps: at least one line is short, or the return line is not the quarterly series, so treat it with a little more caution.

Compound annual growth rate (%)

Compound annual growth rate over each period, %. Revenue, profit and EPS come from yearly figures; the stock price row is price growth over the same periods. A dash means no figure for that period, or the starting year was a loss.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP earned a ROE of 20% in FY25. That is up from a low of 9% in FY21. Its return on capital used (ROIC) is 3.9 percentage points above its cost of capital, so growth here adds value, not just size.

Return on equity (ROE) is the profit the business earns on its shareholders’ money. We do not have the full capital split, so ROE is the longest history we can draw here.

It comes from a 22.2% net margin and 0.37× asset turnover (sales divided by assets).

Why the return is what it is (FY25): a 22.2% net margin × 0.37× asset turnover × 2.46× leverage (assets divided by equity) ≈ 20.2% on equity. The margin does most of the work; borrowing is a big part of it.

The key test, return on capital used minus the cost of capital: 9.6% − 5.7% = +3.9 percentage points. The 5.7% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. Positive but thin: it creates value with little room for error.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP has total debt of BRL 51.7 B against shareholder equity of BRL 45.3 B as of Jun 2026, so its debt is 1.14× its equity. Year by year, that ratio went from 0.71 in FY21 to 0.95 in FY25.

Debt-to-equity shows how much of the business is paid for with borrowed money. Lower is safer, and the direction matters as much as the level.

Keep that borrowing in mind when reading the returns on this page.

We have no ownership or short-position figures for Companhia de Saneamento Básico do Estado de São Paulo - SABESP, so this section says so rather than fill the gap. At normal trading volumes, closing those positions would take about 1.5 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead.

There is no quarter-by-quarter list of owners here, so we look at short interest: the share of tradable shares held in short positions, which gain if the price falls.

For Companhia de Saneamento Básico do Estado de São Paulo - SABESP, the Z-score is not available, so we say so rather than guess one. It estimates how far the balance sheet is from trouble; it is not a forecast of failure. The debt, cash-flow and return sections show the balance-sheet figures we do have, each with its own date.

The Z-score estimates how far a company is from balance-sheet trouble. Above about 3 is safe; below about 1.8 is the danger zone. It was built for manufacturers, so it is not used for banks and lenders.

40.5 out of 100, rank 11 of 13 in Utilities - Regulated Water, with 79% of the evidence available.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP scores 40.5 out of 100 against the 13 companies it is compared with in Utilities - Regulated Water, ranking 11. The valuation scores well, but earnings are not improving yet, so the business does not back up the low multiple so far.

The four parts add up to the total exactly: 7.9 + 15.3 + 16.5 + 0.8 = 40.5. This is the same number shown on the industry page; it is worked out once for the whole group and read here.

What would change it: The score would fall if profit growth turns negative or margins stop improving while the share price lags its sector.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP ranks 11 of 13 Utilities - Regulated Water companies on the 4-Factor Sector Score, with 40.5 out of 100.

Missing figures are not scored as bad. They lower the confidence and pull the final score toward the middle. Relative strength counts only when the company has a reading for this week; with no reading, that factor is left out and its 20 points are shared across the other three in proportion. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step path the industry is placed on (basing, turning, breaking out, leader, fading, asleep), read from how many weeks running it has led S&P 500 and whether that lead is growing or shrinking. It describes where the share price stands, not the direction of earnings, and it is not a recommendation; it is left blank for a company whose weekly history is too short or too stale to read.

The figures in this ranking come from the industry comparison: results through the Jun 2026 quarter, and the P/E at that quarter's end. The sections above use the latest weekly price, so a P/E or return there can differ a little from the one here. The stage words in this ranking (such as losing its lead or breaking out) describe the lead over the index, not the price phase in the price section.
