Costs remained stable as a percentage of revenue when comparing 3Q23 vs. 2Q23, reflecting the company's business mix. There were no highlights in the composition of costs in this quarter. The largest cost components – Personnel, Third Parties, Maintenance, Fuel and Travel – represented more than 85% of total costs.

Rental costs were reversed this quarter, due to the reclassification of expenditure relating to 2023 of operations in North America, which did not adopt the IFRS 16 standard.

GROSS PROFIT

 

Gross profit grew over 3Q22. Gross margin for 3Q23 reached 30.0%, a result of 1.0 pp. higher than 3Q22 and up by 4.2 pp. compared to 2Q23. The improvement in gross margin in relation to 2Q23, is due to better performance in Brazil and Canada.

It is worth noting that part of the margin increase in 3Q23 is due to the accounting adjustment to IFRS 16 carried out in this period and will not be recurring.

CAPEX RESPONSE

In 3Q23, addition of Fixed Assets was R$75.6 million. In Response, we invested in Latin America in the new training camp in Chile and in Brazil, we acquired equipment to support the expansion of the operation, mainly for air services.
