LETTER TO SHAREHOLDERS

To our shareholders

We are pleased to present Ambipar Response the results for the second quarter of 2024, marking a period of record achievements in revenues, EBITDA, and net income. This represents our first formal quarterly earnings report, aligning with our commitment to enhance communication with the investor’s community, alongside improvements within our organizational structure and the overall Ambipar Group.

During this quarter, we reported net revenue of R$740.5 million (USD137.4 million), reflecting a growth of 22.5% when compared to the second quarter of 2023, with Brazil notably demonstrating an expansion of 65.3%.

EBITDA for this quarter amounted to R$191.9 million (USD35.6 million), achieving a margin of 25.9%. This indicates an increase of 27.7% in EBITDA and a 1.3 percentage point rise in the margin relative to 2Q23, primarily attributed to the substantial contribution from our Brazilian operations.

Our net income for the quarter reached R$89.2 million (USD16.6 million), representing an increase of 89% compared to the previous year’s second quarter. This growth can be attributed to an increase in EBIT, a reduction in financial expenses, and the recognition of tax credits associated with fiscal losses incurred in 2023.

In operational highlights, we emphasize our effective response to the Baltimore Bridge incident in the United States, where our dedicated team managed the situation from the outset until the successful removal of the vessel and reopening of the channel. We continued to offer critical support services for even after the vessel arrived in the port, including emergency responses to hazardous materials, waste de-characterization, transportation, and final disposal.

Furthermore, we were called to address the immediate aftermath of the floodings in Rio Grande do Sul, Brazil, which was recognized as one of the largest climate-related disasters in the country. In our Environmental Services division in Brazil, we initiated significant projects such as bioengineering, dredging, and the execution of marine monitoring programs. We also renewed our contract with the Maritime Agency and the National Coast Guard of England (MCA) for the management and operation of oil spill response in the United Kingdom.

To further strengthen our capabilities, we expanded our team by adding key personnel and finalized our objectives and key results (OKRs) for both the corporate structure and all business units.

4

Additionally, we are advancing with the first phase of our ERP implementation in North America and completed the initial phase of the Emergency Command Center in the United States. This progress will facilitate the integration and standardization of our operational services, consolidating our Level 1 (telephone service), Level 2 (crisis management), and Level 3 (field services), like the successful model we have developed in Brazil.

Command Center in Houston – Texas

We remain committed to focusing on organic growth, cross-selling opportunities, and the integration of operations to enhance synergies. Our continued emphasis on system implementation and the positive expansion of financial indicators will strengthen our balance sheet, improve cash flow generation, and support deleveraging efforts.

I would like to express my gratitude to all stakeholders, particularly our employees, for their trust and support. We reinforce our continuous dedication to ongoing improvement.

Sincerely,

Rafael Espirito Santo

Ambipar Response registered net income of R$89.2 million in 2Q24, with a net margin of 12.0%.

Compared to the same quarter of the previous year, net margin increased by 4.4 p.p. High margin is explained by higher EBIT margin, better financial result and the recognition of tax credits linked with fiscal loss in 2023.

CAPITAL STRUCTURE

On June 30, 2024, financial gross debt reached the amount of R$1,151.5 million, a reduction of R$96.2 million in relation to the balance as of December 31, 2023, mainly due to pre-payment from the 1st issue of debentures (Brazilian local bonds) and amortization of certain loans and financing.

In addition to the indebtedness with financial institutions, Ambipar Response also has a credit line with its parent company, Ambipar Participações. This line mimics the terms of the green bond raised by the parent company in the beginning of 2024 and amounts to US$200 million. Considering this related parties loan, the total amount of gross debt was R$2,355.0 million, an increase of R$486.5 million, partially explained by the monetary variation on the related party’s loan. This loan has been swapped to BRL and the SWAP results is accrued as a related party asset in the balance sheet.

Considering the related parties net balance, the total amount of net debt was R$1,627.5 million an increase of R$211.6 million YTD, mainly due to payments of deferred installments of past M&A’s, which amounted R$137 million in the period.

Financial Leverage based on Covenants criteria reduced from 1.08x to 0.78x in the comparison between June 2024 and December 2023. Also in June 2024, considering Related Parties loans, the leverage increased from 1.86x to 2.12x.

1- Considers a 30% tax rate; 2- Disregard intangibles

Return on Invested Capital minus intangible assets (“operating ROIC”) allows for an approximate estimate of the return on investments made in operations.

Return on Invested Capital (“ROIC”), which incorporates intangible assets into the invested capital base, mainly composed of goodwill paid for acquisitions.

M&A investment, at first, presents a lower ROIC, due to goodwill paid on acquisition. Once acquisitions become part of our operations, the expected return on the marginal investment made tends to follow the Operating ROIC, since the invested capital is allocated to the acquiree's operations and does not include goodwill.

In the medium term, therefore, we expect convergence between the ROIC and the operational ROIC.

CAPEX

We continued to invest in the upgrade of our existing asset base and the organic expansion of our footprint, especially in North America. In 2Q24, the addition of fixed assets in Response was R$49.5 million. We invested in new aircrafts in Brazil, and in the implementation of contracts for monitoring coastal fauna and flora. Abroad, we made investments to open new operational bases during 2H24 in North America, in adjacent geographies to our current operations.

Gains from operational leverage have materialized in lower capex intensity per revenue, even when measured over the last twelve months.
