MESSAGE FROM ABOUT SUSTAINABILITY AT PRODUCTS WITH ENVIRONMENTAL SOCIAL GOVERNANCE AND GRI, SASB, AND TCFD OUR CEO HUBBELL HUBBELL IMPACT STEWARDSHIP RESPONSIBILITY ACCOUNTABILITY DISCLOSURES GRI STANDARD DISCLOSURE EXPLANATION WATER AND WASTE GRI 3: Material 3-3 Management of material topics For information on our approach to managing energy, GHG emissions, water, and waste, see GRI 3-3 for the material topic, "energy and Topics 2021 emissions." In 2023, we set water and waste goals to drive improvements in our sustainability performance. These enterprise-wide goals include reducing water usage by 25% and reducing hazardous waste generation by 30% by 2030, compared to a 2021 baseline. The new environmental data software solution we implemented in 2022, which provides a more comprehensive picture of our waste, recycling, and water inventory, will help us identify and pursue opportunities to reduce our water usage and waste generation. Our e昀昀orts to reduce our water usage include behavior changes that promote water conservation and installing low-昀氀ow water valves and leak detection mechanisms in our facilities. As water availability and scarcity varies considerably from region to region, we continue to evaluate opportunities to minimize the amount of water we consume on a local basis. We are also focused on reducing the amount of waste generated from our operations, as well as reducing or eliminating hazardous materials in our products. Whenever feasible, we are dedicated to pursuing measures to reduce, recover, reuse, or recycle waste in our operations.

The water usage of consolidated joint operations are included pro rata, based on our 50% interest. Water usage for select sites where Hubbell does not pay the utility bill (i.e., primarily tenant-shared o昀케ce space) is excluded from the reported water usage. Estimates are used where primary data is not available. Water usage is reported in kilogallons (kgal). 2. In 20 22, we completed our implementation of a software solution that enables us to track water usage across our enterprise. This led to an improvement in our data measurement methodology and the number of sites and sources included in our inventory. As a result, we restated our historical water usage. 3.  Hubbell established a threshold for signi昀椀cance of 5% or greater in Hubbell’s total base-year water usage for the company’s rebaseline policy. While our new environmental goals reference a 2022 baseline, we applied this policy to our 2019-2021 historical data to help us track Hubbell’s environmental reduction progress over time. In October 2021, Hubbell initiated the sale of its Commercial and Industrial Lighting business, which was completed in 2022. This divestment triggered our rebaseline policy and our restated historical data re昀氀ects this recalculation. In addition, Hubbell grew its business with acquisitions in the second half of 2022 - PCX Holdings LLC, Ripley Tools, and REF Automation. These acquisitions did not trigger our rebaseline policy for historical data, however these sites are included in our inventory for 2022 onward. 69
