Closing prices from the base up to 2025-11-13. The starting price is adjusted by the corporate actions checked against the price (the small mark says how many); a jump they do not explain leaves the window blank. Reinvestment buys more shares at the close of the ex-date, with no tax or cost; only the main ticker class. The real line divides the reinvested return by the IPCA accumulated in the window (Banco Central series 433, monthly, edge months pro rata by days); the latest month is only published around the 10th of the following month.

Indicators, year by year
Four indicators as charts and the full table below. A hollow point carries a caveat; a gap is a year without the figure — we never draw a line across a hole. In the table, the arrow opens the path from the figure down to the line in the regulator's file; a cell with ! carries a caveat; a dashed dash is a suppressed figure — hover to see why. Nothing is hidden.

The three statements behind the ratios — income statement, balance sheet and cash flow — in the standardized lines, consolidated as filed (or parent-only when that is what the company files). EBITDA and net debt follow the published methodology; gross debt, cash and investments and free cash flow are sums the line names spell out.

The two right-hand columns come from the quarterly filing (ITR): the latest quarter alone and the last 12 months (TTM) built by the same identity as the TTM P/E. EBITDA and net debt have no quarterly series here.
The current year, quarter by quarter
As the company filed it in its interim report. The fourth quarter does not exist on its own in that filing — the closed year comes in the annual one, and we do not derive a Q4, so that a figure we computed never sits beside the figures the company reported. Filed on is the date the report became public, and the price is taken from it.
