Gross revenue reached R$737.1 million in 1Q24, 17.5% higher than 1Q23, due to the 59.9% growth in revenue from Brazil, offset by the 3.6% reduction in international revenue. The 6.9% reduction versus 4Q23 comes from the 14.9% drop in international revenue, mainly in North America (19.8% reduction), which was partially offset by the 5.1% increase in Brazil.

•Gross Revenue Brazil grew in all comparisons, driven by the provision of emergency services, especially rail and air, and by growth in environmental response.

•The growth in subscription revenue is mainly due to medical services.

•Within the quarter, the Company was called to deal with a road emergency, caused by a truck overturning in Joinville/SC which spilled a chemical product (sulfonic acid) into a spring and interrupted the city's water supply.

•The 13.2% drop in revenue in 1Q24 vs 1Q23 is due to the devaluation of the Chilean peso, as in local currency revenue showed mid-single digit growth. When comparing 1Q24 with 4Q23 in local currency, the reduction was low single digit.

•We opened a new base in Mexico, at the request of a client in the chemical sector, to support their operations, and we began prospecting for new clients to leverage organic growth in this region.

•The 10.5% drop in revenue in 1Q24 vs 1Q23 was mainly due to the major maritime oil spill emergency in the Strait of Gibraltar in 1Q23, which was partially offset by the response to oil spills in Tobago and at a refinery in Ireland throughout 1Q24.

•The drop in revenue in North America in the quarterly and annual comparison comes from (i) the drop in revenue in Canada, mainly due to the end of services linked to the Trans Mountain Pipeline project and (ii) fewer emergency services due to pipeline leaks, silos and asbestos decontamination in the USA.

•The drop in organic revenue in the annual comparison was partially offset by the entry of revenue from Bulldog (Alberta), now Ambipar Response.

•We have been providing services on the ship accident on the Baltimore bridge since the day of the accident. Today we have around 30 people allocated to this emergency, being the only private company to deal with the incident, in addition to 5 American government entities, demonstrating our capacity and quality in executing/conducting services.
