LETTER TO SHAREHOLDERS

Toour shareholders

In 2023, Ambipar Response (hereinafter referred to as "Response" or "the Company") proudly completed its listing on the NYSE American, achieving a gross capitalization of US$ 174 million. This listing not only amplifies our visibility but also fortifies our financial position, grants us access to the world's most advanced capital markets, and places us at the forefront of corporate governance standards.

As this letter marks our inaugural results release, we have structured it into three main sections:

  1. Historical Overview and Strategy

  2. Capital Allocation

  3. Final Thoughts

HistoricalOverview and Strategy

The trajectory of listing Response on the NYSE American dates back to 1995 when Tercio Borlenghi Junior started a small in-house Emergency Response business to protect their own logistics operations from environmental risk when transporting HAZMAT. Fast forward decades, this original family-owned business effectively became a big company, subsidiary of Ambipar Group, listed as a public company.

From those early years, and most prominently from 2010 to current days, Ambipar Response has undergone through incredible transformation. Our Company witnessed a rapid acceleration in our global growth, a solidification of our value proposition, consolidation of its leadership in several markets, and a notable increase in brand awareness.

We expanded and streamlined our operations into four core business units: emergency response, marine response, industrial response, and environmental response. We also established a presence in four key regions, adopting a matrix management approach. Our primary objective is to offer a comprehensive suite of services from these business units in the regions we operate.

Our clientele operates in sectors that are fraught with operational and environmental risks – encompassing manufacturing, chemicals, pulp and paper, mining, and Hazmat logistics. Clients require specialized services providers capable of executing higher risk services – such as tank cleaning, decontamination, decommissioning, environmental consulting, emergency response, confined space cleaning, handling of contaminant materials - that ultimately safeguard their assets, personnel, and the environment.

Our vision for Response is to be the premier global provider of such risk environmental services, delivering a standardized and complete portfolio of services to our clients wherever they may be.

| --- |

Our business model emphasizes standardization and readiness at scale, built on four pillars:

1. Highly<br> trained personnel
2. Standardized<br> equipment and procedures
--- ---
3. Centralized<br> command centers
--- ---
4. Technical<br> expertise
--- ---

These pillars underpin our rapid growth while ensuring we maintain the highest quality of service in the field.

Scale is instrumental in achieving optimal returns on investment. It enables us to share assets and personnel across vast geographies, ensuring efficient asset utilization and maximizing the potential of our resources – akin to "squeezing more juice from the same oranges."

CapitalAllocation

Our business presents great organic and inorganic investment opportunities.

We are constantly presented with opportunities to deploy capital at attractive returns to invest in service centers, vehicles, vessels, helicopters, equipment, and personnel. Throughout our journey, we’ve also come across acquisitions as a way to accelerate growth, bring great people and services to our Company.

As evidenced by our organic growth, operational margins, and ROIC, our acquisitions have become part of the Ambipar Response ecosystem and consistently added economic value and positioned us to keep on growing profitably. The underlying reason relies, among others, on rebranding acquisitions to Ambipar Response, upgrading assets, training personnel, bundling services and training sales teams enables Response to achieve constantly growing results.

FinalThoughts

Many of the markets we operate in, notably North America, are fragmented and demand standardized, high-quality services to cater to their vast dimensions and extensive industrial and supply chains. We have successfully established leading positions in Brazil and LatAm and intend to replicate our successful playbook in other regions. This presents a timely opportunity.

Our NYSE American listing has endowed us with an additional currency – the AMBI shares – enabling us to pursue strategic acquisitions and attract individuals keen on contributing to the construction of a global leader in environmental risk services.

We extend our heartfelt gratitude for your partnership as an investor and shareholder. Our commitment remains unwavering: to build a reputable, profitable, and purpose-driven company, always prioritizing our mission to protect the environment, businesses, and communities.

As we embark on this new chapter as a publicly-traded company, we are resolute in our commitment to attract shareholders who resonate with our vision and are willing to support us in the long run.

GROSS PROFIT

QuarterlyGross Profit(R$ million) and Margin (%)

Gross profit grew over 2Q22. Gross margin for 2Q23 reached 25.8%, a result of 1.0 pp. lower than 2Q22 and up by 1.6 pp. compared to 1Q23. The improvement in gross margin in relation to 1Q23, is due to better performance in Brazil and Canada.

In 2Q23, Ambipar Response presented a negative net financial result of R$51 million, resulting from the increase in interest rates and the increase in debt. The debt increase was mainly for capex and M&A.

Ambipar Response registered net income of R$47.1 million in 2Q23, with a net margin of 7.7%.

Compared to the same quarter of the previous year, net income grew by 35%, with a reduction of 2.8 p.p. in net margin. Profit growth derives from the growth in operations, while the drop in margin is explained by the negative financial result and the contribution of business segments and regions to the consolidated result.

The portion of net income allocated to non-controlling shareholders grew in 2Q23, as we made several acquisitions of companies throughout the year of 2022 where founding partners remain in the business as minority shareholders. This way of carrying out acquisitions ensures that we maintain expertise and continuity in the acquired companies, and it is a form of long-term alignment.

CAPITAL STRUCTURE

On June 30, 2023, financial gross debt reached the amount of R$ 1,256.4 million, a reduction of R$ 61.7 million in relation to the balance determined on December 31, 2022, mainly due to the issue of debentures and funding of loans and financing. Considering Related Parties, the total amount of gross debt was R$ 1,863.3 million a reduction of R$ 224.7 million.

Financial Leverage based on Covenants criteria reduced from 1.51x to 0.94x in the comparison between December 2022 and June 2023, due to the cash generation related to the Company's IPO occurred in March.

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 company's ROIC and the operational ROIC.

CAPEX

In 2Q23, addition of Fixed Assets was R$41.9 million. In Response, we invested in Latin America in the new training camp in Chile and in the acquisition of equipment to be used in outsourcing contracts.

As for 6M23, Brazil still demanded capex for helicopters, which are typically demanded to fight fires in the rainforest and transport people to remote areas, and we continued investing in vehicles for industrial services and emergency response in North America.
