A LETTER FROM OUR CEO

As we partner with our clients on the many projects ahead, we are keenly aware of our role in developing and implementing solutions that will support a low carbon economy and transform the future for generations to come. We do so with commitment and a clear understanding of our opportunity and obligation to positively impact the three pillars of
sustainability: Environmental, Social, and Governance (ESG).

In this fiscal year, we strengthened our ESG governance, implementing recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD), as well as the previously adoptedframework provided by the Sustainability Accounting Standards Board (SASB). We did so to further ensure that financial risks and opportunities related to climate change become an integral part of our risk management and strategic planning processes.

We also continued to strengthen our focus on quality and safety, training and development, and diversity, equity, andinclusion. Led from the top, these aspects of social sustainability benefit from concerted efforts across our own organization, on our project sites, through our relationships with
suppliers and vendors, and in service to our communities.

Finally, recognizing that the scope of sustainability requires consideration across an ever-changing landscape and every aspect of our business, in fiscal 2021 and fiscal 2022, we took time to carefully evaluate and develop a plan to transform our own organization to better support our
clients, deliver on our growth objectives, and achieve long-term sustainability for all stakeholders.

As a leading engineering and constructioncontractor, Matrix is proud to serve the energy and industrial markets and tosupport the low carbon objectives of our clients, whose infrastructure is essential to improving lives and building a better world.

As we continue our sustainability journey, I am pleased to share our fiscal 2022 ESG
accomplishments as well as those areas where we believe we can do better in coming years.

I am incredibly proud of our employees and their commitment to sustainability. We look forward to the ongoing journey ahead and to working with all stakeholders as we fulfill our brand promise to MOVE TO A HIGHER STANDARD.
