Grupo Mateus stock holds at BRL 4.91 as profit pressure grows

Grupo Mateus stock (BRGMATACNOR3) closed at BRL 4.91 on September 18, 2026, down 0.41 percent from the prior close of BRL 4.93 on B3. The latest operating data show a sharper issue beneath the stable quotation: operating profit fell 22.3 percent to BRL 888.5 million in the January to June 2026 period.

Profit pressure reaches BRL 888.5 million

According to Valor on September 22, 2026, Grupo Mateus reported operating profit of BRL 888.5 million for January through June, 22.3 percent below the comparable period. The comparison gives the stock a more cautious fundamental backdrop than the modest 0.41 percent daily decline suggests.

The result also creates a clear metric for the next report: revenue growth would need to translate into operating leverage for the earnings profile to improve. A lower operating result can reduce the capacity to absorb logistics, labor and store-expansion costs even when sales volumes remain resilient.

Stock trades near BRL 5

TradeMap recorded a closing price of BRL 4.91, an intraday high of BRL 4.92, a low of BRL 4.80 and volume of 15,675,363 shares on September 18, 2026. The same quotation places the immediate trading range at BRL 0.12, or 2.44 percent of the closing price.

For investors, the contrast is concrete: the stock lost BRL 0.02 on the session, while operating profit declined BRL 255.0 million against the prior comparable period implied by the reported 22.3 percent rate. The market response therefore leaves profitability, rather than the daily quotation, as the central numerical checkpoint.

BRL 4.91 remains the reference level

Grupo Mateus stock stood at BRL 4.91 on B3 as of September 18, 2026, with the prior close at BRL 4.93. The next material valuation signal is whether the company can reverse the 22.3 percent first-half operating-profit decline in a subsequent reporting period.
