TETRA TECH INC

We assess the impact of climate risk and opportunity on our operations and business periodically, with the oversight of our Board of Directors. Climate risk is a consideration in business continuity planning and security in regions that may experience climate-related disruptions due to extreme weather, fires, or flooding. Climate related impacts may also create increased demand for our services for response and longer-term recovery needs. In some cases, we may be working in regions that also experience socio-political impacts and security disruptions due to the impacts of extreme weather or prolonged drought conditions. As a professional services company, our workforce is highly mobile, able to work remotely, and can in most cases quickly adapt to changes in local conditions. We have business continuity planning and processes in place to address any acute impact to locally affected operations and have the ability to rapidly move to remote and flexible working arrangements while restoring or relocating affected operations. We maintain a strong information technology infrastructure to facilitate remote working and provide virtual access to systems. Our enterprise and project data is accessible through cloud-based systems, reducing the risk of localized disruptions of data access and computer systems. Our offices are typically leased, so we are not at significant risk of physical building assets being impacted. Selecting project activities can be impacted by climate related events; however, these are addressed through our extensive project risk management process. Climate-related disruptions do, in many cases, result in increased opportunity for project work for Tetra Tech. We provide post-disaster response services and may have additional demand for our expertise if there is an increase in the frequency of climate related events. We are able to mobilize rapidly to deploy additional staff and resources to affected areas. Furthermore, our business includes providing a wide range of water, environment and sustainable infrastructure services, many of which are increasingly in demand to address the longer-term impacts associated with drought, water scarcity, heat, flooding and fire risk.
