Companhia de Saneamento Básico do Estado de São Paulo - SABESP

Price story Before the numbers, the tape. A stock price moves through four repeating seasons: a flat base (stage 1), an advance (2), a top (3), a decline (4). Where the price sits in that cycle frames everything below.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP trades at $5.3, building a base and 8 weeks into that stage. That is −4.9% against its own 200-day average. It sits at 37% of a 52-week range of $4 to $7.

Today the stock is building a base — week 8 of stage 1. At $5.3 it trades −4.9% versus its 200-day average and sits at 37% of its 52-week range ($4–$7).

Against the market, two honest reads. Cumulative: over the last 10.2 years the stock moved +205% while the S&P 500 moved +255% — behind the index over the full window. Recent form: on a trailing-13-week view the stock is currently behind (19 weeks and counting; last ahead the week of 2026-05-08) — the ribbon below is that same metric, week by week.

What would end the trend, mechanically: two Friday closes in a row below the 200-day line. That is the exit rule — no debates.

Valuation P/E is the price of $1 of annual profit: how many dollars the market pays for each dollar the company earns in a year.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP trades at 11.8× P/E, against too little history to rank. This places the multiple against the stock’s own record, and says nothing about what the business is worth.

Today's P/E of 11.8× is against too little history to rank. This is a comparison against the stock's own history — not a claim about what it is worth.

Why the multiple sits where it does: over the past year annual EPS moved −11.8% against a +10.9% price move — the price outran earnings, pushing the multiple UP its own range.

The price move, decomposed: over 3y, of the +30.2%/yr price move, ~+32.5%/yr came from earnings growth and ~−2.3 pp from the multiple (compressing). The split is the honest approximate (price return minus earnings growth); it makes the rally itself visible instead of hiding it behind the percentile.

Put together: the multiple is unremarkable against its own past, so the story rests on the earnings line underneath it, not the multiple.

Stage: Mixed Every business sits somewhere on a fundamental arc, and this page names the spot before anything else. The last twelve quarters of revenue, profit and EPS growth — plus the return the business earns on its capital — are read as curves: Deteriorating (the curves are falling), Turning around (a trough has just formed and the last few quarters lift off it), Improving (the climb off the trough is sustained), Consistent (steadily positive with healthy returns), Topping out (still high but decelerating from the peak). When the curves genuinely disagree the read is Mixed; too little history is No read. CAGR (compound annual growth rate) is the smooth yearly pace that turns the starting value into the latest one — the fairest way to compare growth across different time spans. Read the columns together: if the 1-year number towers over the 10-year, recent growth is running hotter than the long-run trend. A dash means that window is not held, or the base year was a loss (where a growth rate is not meaningful).

Companhia de Saneamento Básico do Estado de São Paulo - SABESP reads as mixed on its fundamental arc. Mixed — no clean majority across the growth curves, ROCE slipping at 22.3% — the per-curve reads carry the story. The read is built from 12 quarters across 4 curves, on full evidence.

Why it matters: when the curves disagree, the per-curve reads above matter more than any single verdict.

Operating margin Operating margin is what is left of every $100 of sales after running the business, before interest and tax. It is the cleanest read on pricing power and cost control.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP's operating margin is 33.9% in the Mar 26 quarter, +0.2 percentage points against the same quarter a year ago. Across the last four quarters the operating margin has moved −29.7 percentage points. Across 5 fiscal years the operating margin has ranged 21.0% to 42.9%.

The latest quarter's operating margin is 33.9%, +0.2 pp against the same quarter a year ago. Across 5 fiscal years the operating margin has ranged 21.0%–42.9%.

🚨 Why the margin moved: operating margin went −29.7 pp year on year while gross margin went −34.0 pp — the loss came mostly from the gross line: input costs and pricing.

Net profit Net profit is what survives every cost, interest and tax — the number EPS, dividends and book value all grow from.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP earned $1.8 B of net profit in the Mar 26 quarter, +18.2% year on year. It is the 5th consecutive quarter of growth. Full-year FY25 profit was $8.5 B. The 4-year compound rate is 38.3%. That is 17.6% of the quarter's revenue.

Why profit moved: revenue contributed +18.1% and the margin +0.2 pp — the quarter was revenue-led, with the margin roughly flat.

Pace comparison, last four quarters: profit +188.3% vs revenue +24.6%. Profit is growing faster than sales — fixed costs are being spread over a bigger base, and each extra dollar of revenue drops more to the bottom line.

Cash flow — the router The P&L says what was earned; the cash-flow statement says what actually arrived. Operating cash flow (CFO) against profit is the cleanest lie detector in the accounts.

Over the last 3 fiscal years 96% of Companhia de Saneamento Básico do Estado de São Paulo - SABESP's reported profit arrived as operating cash — the cash follows the profit. In FY25 that was $8.4 B of operating cash against $8.5 B of profit. After $13.7 B of capital spending, $−5.4 B was left as free cash.

FY25: operating cash of $8.4 B against reported profit of $8.5 B, leaving free cash of $−5.4 B after $13.7 B of capital spending. Across the last 3 fiscal years the conversion rate is 96% of profit.

Cash-flow readings here are annual — that is the resolution our series carries, so this section moves once a year.

Why: conversion is measured cleanly, but the working-capital day-counts behind it sit below what we hold — the move is shown without inventing its driver.

Router verdict: the visible cash user is investment — the next section checks what the spending is buying.

Where the cash goes Working capital is the cash tied up between paying suppliers and getting paid: debtor days (customers owe), inventory days (stock waits), and the cash conversion cycle (the whole loop, in days of sales).

Companhia de Saneamento Básico do Estado de São Paulo - SABESP does not report the debtor, inventory and payable day-counts a cash cycle is built from, so this section reads the investment side instead. Capital spending ran $26.0 B over the last 3 years. Averaged over those years that is 22.8% of FY25 revenue a year.

Working-capital day-counts are not in our numbers for this stock, so this section reads the investment side — where the cash is being put to work.

On the investment side: capital spending of $26.0 B over the last 3 fiscal years.

The synthesis: the cash is going into capacity, not disappearing into the cycle — the question becomes whether the new capacity earns.

Return on equity Return on equity (ROE) is the profit the business earns on its shareholders’ money. With the full capital-employed split not in our numbers, ROE is the cleanest long ladder we can draw here.

Companhia de Saneamento Básico do Estado de São Paulo - SABESP earns a ROE of 20% in FY25. That is up from a trough of 9% in FY21. Return on invested capital clears the cost of that capital by +4.0 percentage points, so growth here adds value rather than only size.

FY25 ROE is 20%, recovered from a FY21 trough of 9% — the full ladder below shows the fall and the climb, undoctored.

Why the return is what it is — the wiring (FY25): 22.2% net margin × 0.37× asset turns × 2.46× balance-sheet leverage ≈ 20.2% on equity. Margin is doing the heavy lifting; leverage is a meaningful part of the equation.

The capstone test — ROIC − WACC: 9.6% − 5.6% = a +4.0 pp spread. The 5.6% is an estimate of this company's own cost of capital — read the sign and the size of the spread, not the decimals. Positive but thin — value creation with little room for error.
