The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- Situation
- Regulated utility. Returns are set by regulation on an approved rate base; the capital spending regulators approve becomes the growth, recovered through allowed rates.
- What moves the needle
- Gross margin has run about 23% and operating margin about 21% through the cycle, a thin spread, but one where almost nothing separates the gross and operating lines — the mark of cost-plus or fixed-price program work, so the contract structure and the order book set the result more than unit volume against a price. On a spread this thin the operating result swings hard on small moves in cost or volume — it has ranged from 1.0% to 28% over the years, so the cost line is where the needle moves. Read this kind of business on rate base and the allowed return. On its own account, the filing leans hardest on customer concentration, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- Return on capital has run in the teens (median 14%, above 15% in 3 of 6 years). Owner earnings agree: roughly 11% of revenue reaches owners as cash, consistently. Returns like these are solid but short of clear franchise economics; whether they hold is what the 10-K settles, not the multiple.
Every line is arithmetic on the company's filings, shown in full in the sections below.

Will it survive?
- ComfortableOperating income R$11.3B ÷ interest expense R$2.0B
What this means
Operating profit covers interest with the kind of margin Graham wanted for a defensive holding. Necessary, not sufficient, it says solvent, not cheap.
- How heavy is the debt, net of cash? R$10.0B · 0.9× operating profitModest net debtCash R$1.9B + ST investments R$358M − debt R$12.3B
What this means
Netting R$2.3B of cash and short-term investments against R$12.3B of debt leaves R$10.0B owed, about 0.9× a year's operating profit (1.1× on the gross debt, before the cash). Net debt is the leverage figure that matters: the cash is already set against the debt. Strategic or illiquid investments aren't counted here.
- Not enough data
What this means
The filing data didn't include the inputs for this check.
Is it a good business?
- Solid through the cycle6-yr median, range 8%–23%; 23% latest = NOPAT R$8.6B ÷ invested capital R$37.8BIndustry peers: median 6%
What this means
The rate the business earns on the money tied up in it, Buffett's north star, because over time a stock tracks the ROIC beneath it. Above ~15% sustained hints at a moat; a return below the cost of capital (~8%) erodes value as a business grows rather than building it — the test Buffett weighs most. The headline is the median of the last 6 years (it ran 23% most recently), so one peak or trough year doesn't set the verdict. Asset-light businesses (R&D expensed, little capital) read artificially high, pair this with Owner Earnings.
- Solid through the cycle10-yr median margin, range 2%–34%; latest R$4.8B = operating cash R$5.5B − maintenance capex R$671MIndustry peers: median 12%
What this means
What an owner could take out without starving the business: operating cash less the maintenance capital it must spend to hold its position — Buffett's owner earnings. That's 12% of revenue this year, a 10% median across 10 years.
- Mostly cash-backedCash from ops R$5.5B ÷ net income R$7.1B
What this means
How much of reported profit showed up as operating cash. Above 1× is reassuring; well below suggests earnings lean on accruals. One year is noisy, growth and working-capital swings distort it, and this is operating cash, not free cash. Watch the multi-year trend.
How is the cash used?
- Reinvests most of itDividends + buybacks R$1.9B ÷ Owner Earnings R$4.8B
What this means
Of R$4.8B Owner Earnings, R$1.9B (39%) went back to shareholders, R$1.9B dividends, R$0 buybacks. Returning most of it is the mark of a mature business with little left to reinvest at a high return; reinvesting most could mean a long runway, or empire-building. The split doesn't say which; the return earned on it (see ROIC) does.
- Investing or harvesting? 0.49×HarvestingCapex R$671M ÷ depreciation R$1.4B
What this means
Descriptive, not a grade. Above ~1× means investing faster than assets wear out (growth, or, sustained for years, today's earnings carrying less depreciation than tomorrow's will). Below means spending less than it's wearing out (efficiency, or a melting asset base). The ratio won't tell you which; the filings will.
Graham’s defensive tests · 1 of 5 met
Graham’s numerical criteria for the defensive investor (The Intelligent Investor, ch. 14), run on the filings. A floor of safety, not a buy signal; many fine modern businesses fail his strictest liquidity rules by design.
- Adequate size —Revenue ≥ $2B (a dollar floor) · R$39.8B
What this means
Big enough to weather a storm. Graham's floor is a dollar figure — about $2B of revenue as a conservative modern stand-in. This company reports in its home currency and we carry no exchange rate, so we show the figure and leave the size bar for you to apply rather than convert it with a number we don't have.
- Strong liquidity MissCurrent ratio ≥ 2× · 0.86×
What this means
Current assets at least twice current liabilities, near-term bills covered without touching the business. Strict by design: many cash-rich modern firms run leaner and miss it, holding their cushion in longer-dated securities.
- Conservative debt MissDebt ≤ working capital · R$12.3B vs (R$1.9B) WC
What this means
Graham's rule that borrowings not exceed net current assets. Capital-heavy and buyback-heavy firms routinely fail it, read it next to interest coverage, not alone.
- Earnings stability NearA profit every year (10-yr record) · 1 loss year
What this means
Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.
- Dividend record MissUninterrupted dividends · 7 of 10 yrs
What this means
An unbroken dividend was Graham's mark of durability. He wanted twenty years; the filings show about ten, and a single suspension breaks the streak. Non-payers, many fine modern compounders, fall outside his defensive net by design.
- Earnings growth PassEarnings +33% over the record · +346%
What this means
At least a third more earnings than a decade ago, averaging three years at each end. Net income (not per-share), so stock splits don't distort it, buybacks and dilution show up in the share-count line instead.
- Moderate price —P/E ≤ 15 and P/E × P/B ≤ 22.5 · decided by the price
What this means
Graham's valuation gate, the wall he kept between a sound business and a sound investment. Three-year average earnings are R$1.98/share (latest year R$2.49), the averaged base the calculator's gate runs on, and book value is R$9.57/share. Enter a price in “What the price implies” just below for the P/E, P/B, and whether it clears. But this is the rule Buffett outgrew: there's no hard P/E law, and a wonderful business can deserve a far richer multiple if the thesis holds, treat it as the bargain-hunter's floor, not a verdict on the price.
Durability & moat, 2015–2024
Whether the record’s returns held, and what the capital reinvested earned.
- Profitable years 9 of 10
What this means
Lost money in 1 year(s), look at what happened there before trusting the average.
- Return on capital ≥ 15% 5 of 9 yrs
What this means
A moat shows up as a high return on invested capital that holds year after year, not one good vintage.
- Operating margin 19% → 24% (3-yr avg ends)
What this means
Through the cycle the operating margin widened — about 19% early to 24% lately, median 21% — pricing power intact or improving.
- Reinvestment, incremental ROIC returns capital
What this means
The capital base barely grew: this business returns cash through dividends and buybacks rather than reinvesting. Judge it on the cash returned, not on compounding.
- Owner earnings growth +11%/yr
What this means
Owner earnings grew about 11% a year over the record.
- Worst year 2019 · 1.0% op. margin
What this means
Stayed profitable even in its hardest year, the resilience that survives recessions.
- Dividend record rising
What this means
Paid and raised the dividend across the record, the continuity Graham prized.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
In its own filing Raised, but not as a competitor
The filing raises AI among its risks, but in other terms (security, regulation, energy or the like), not as a competitor to its product; it frames AI mainly as a capability.
AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat, and the company is using it that way.
Read from the filing's own risk factors, paired with the industry's structure under its SIC code; the durability is read above, the price below.

How the cash was used, 2015–2024
Over the record, the business generated R$38.8B of operating cash; how management split it reads as a balanced allocator, splitting cash between the business, owners, and the balance sheet.
- ReinvestedR$2.7B · 7%
- DividendsR$5.0B · 13%
- Retained (debt / cash)R$31.1B · 80%
- Returned to ownersR$5.0B
14% of the owner earnings the business produced over the span, R$5.0B as dividends and R$0 as buybacks.
- Net change in share count127.3%
The diluted count rose from 1258M to 2861M: issuance (stock pay, deals) outran any buybacks, so owners were diluted on net.
- Dividend recordR$0.66/sh
Paid in 7 of the years on record, the per-share dividend growing about 31% a year. It was cut at least once along the way.
- Return on what it retained20%
Of the earnings it kept rather than paid out (R$20.9B over the span), annual owner earnings (first three years vs last three) grew R$4.1B, so each retained R$1 added about 0.20 of yearly owner earnings. Buffett's test, run on owner earnings instead of market value.
Buybacks are gross of stock issued to staff; the share-count line above is the net of that, the figure that decides whether owners gained. The average price paid blends a year of purchases (and any accelerated repurchase), so it is close, not exact. The record of where the cash went and on what terms.
Acquisitions & goodwill
from the balance sheet & the 10-year cash-flow recordGoodwill grows only when a company acquires and falls only when it concedes it overpaid. The size of that bet, the cash put into buying rather than building, and how much has already been written off.
Goodwill & intangiblesR$16.8B28% of all assets; the premium carried on the balance sheet for businesses acquired
Against book equity0%goodwill is this share of book equity; the rest is the company’s own retained and paid-in capital
Cash spent acquiringR$0over 10 years buying other businesses, against R$2.7B of capital spent building
None written down over the record; the goodwill is still carried at full cost. That is the deals holding their value on the books so far; whether they keep doing so is the test an owner watches, since the write-down, when it comes, is the admission the price was too high.
