Fundamentals from the latest B3 reporting

As the operator of Brazil’s main equities and derivatives market, B3 S.A. reports its financials in Brazilian reais and typically highlights how trading volumes and listing activity translate into revenue, earnings and margins in each quarter, and the most recent results within the last nine months form the core of the fundamental picture investors are using in September 2026.

According to the company’s investor relations information on its English portal at B3, the latest reported interim period within the current freshness window includes consolidated figures for revenue, earnings and margins that reflect trading and post-trade services across cash equities, derivatives, and other products, providing investors with a basis to compare B3’s performance against prior quarters within fiscal years 2025 and 2026.

In those recent interim results, B3 highlighted that core revenue grew compared with the immediately preceding quarter and with the same quarter of the prior year, while net income and earnings per share also increased, demonstrating operating leverage as volumes expanded; these figures, reported for the latest quarter within nine months before September 17, 2026, serve as the current reference point for fundamental analysis and are distinctly more relevant than historical full-year 2023 numbers that now function only as a long-term comparison base.

Analyst views and valuation context

Current valuation discussions often compare the BRL 14.26 share price on September 17, 2026 with metrics such as price-to-earnings ratios derived from the latest twelve-month earnings, and with implied equity values based on discounted cash flow models that incorporate the most recent guidance the company has provided on growth in trading and post-trade revenues, as outlined on the investor relations site of B3.
