Analysis of the Economic and Financial Performance of Companies
Listed on B3 during the Pre- and Post- Covid-19 Pandemic Period
RESUMO

A pandemia global da Covid-19 teve efeitos significativos na economia,
afetando diferentes setores e empresas ao redor do mundo.
Neste estudo, foi analisado o desempenho econômico-financeiro das
empresas listadas na B3, a bolsa de valores brasileira, no período pré
e pós- pandemia (2017-2022). Foram analisadas duas categorias de
empresas: empresas mais/muito afetadas e menos/pouco afetadas pela
pandemia. A análise teve foco no impacto que a pandemia de Covid-19
teve no desempenho das empresas destes dois grupos, buscando testar
se este impacto foi diferenciado de maneira estatisticamente significativa.
A análise revelou que a pandemia de Covid-19 trouxe problemas maiores para as empresas do grupo mais/muito afetadas em comparação com as empresas do grupo menos/pouco afetadas em relação à capacidade de honrar dívidas (problemas de liquidez), ao desempenho em termos de rentabilidade e da margem líquida e ao endividamento. Há, portanto, nos resultados, indícios de que, com o advento da pandemia de Covid-19, as empresas do grupo mais/muito afetadas tiveram impactos significativos de redução da liquidez e da rentabilidade/lucratividade e de aumento do nível de endividamento, quando comparadas com as empresas do grupo menos/pouco afetadas. Isso mostra que a Covid 19 afetou as empresas de maneira distinta, dependendo do setor de atuação.

ABSTRACT

The global Covid-19 pandemic had significant effects on the economy,
impacting different sectors and companies around the world. This study analyzed the economic and financial performance of companies listed on B3, the Brazilian stock exchange, during the pre- and post- pandemic period (2017-2022). Two categories of companies were analyzed: companies more/very affected and less/little affected by the pandemic. The analysis focused on the impact of Covid-19 pandemic on the performance of companies in these two groups, aiming to test whether this
impact was statistically significantly different. The analysis revealed that
the Covid-19 pandemic brought greater problems to the companies in the
group that were more/very affected compared to the companies in the
group that were less/little affected in terms of their ability to honor debts
(liquidity issues), performance in terms of profitability and net margin, and
indebtedness. There are, therefore, in the results, indications that, with the
advent of the Covid-19 pandemic, the companies in the group most/very
affected had significant impacts of reducing liquidity and profitability and
increasing the level of indebtedness, when compared to companies in the
group less/little affected. These results show that Covid 19 affected companies differently, depending on the sector in which they operate.
