The company reported a net income of R$1.25 billion, aligning with market expectations.

The company posted net revenue of R$2.48 billion, up 2.1% year-over-year, while recurring EBITDA reached R$1.73 billion (+1.2% YoY).

What Are Analysts Saying About B3’s Future?

Opinions are split. BTG Pactual remains optimistic, calling B3 a "clear way to bet on Brazil’s monetary easing cycle," praising its attractive valuation and robust capital-return policy (dividends + buybacks). Meanwhile, skeptics argue that reduced exposure to equities dilutes its upside in a bull market. Ativa Investimentos highlights B3’s cost control and innovation efforts, such as integrating recent acquisitions to drive structural growth. "The stock isn’t just riding the wave—it’s building its own," says one analyst.

Short-term traders, though, might find better opportunities elsewhere, given the stock’s 37% YTD run. "I’d wait for a pullback," admits a São Paulo-based fund manager. "But if rates drop faster than expected, B3 could skyrocket." Data from TradingView shows the stock trading at 12x forward earnings—below its 5-year average—suggesting room for multiple expansions.
