In the Fall of 2022, we encouraged our employees to give back to their communities through volunteering and service. As an o昀昀shoot of our Hubbell Helping Hands month of giving campaign in previous years, we designated November of 2022 as our enterprise-wide “Month of Giving Thanks.” During this campaign, Hubbell employees across our enterprise took the theme of giving thanks to heart by participating in volunteer events and activities that bene昀椀ted their local communities. Many of our sites in the US focused on addressing food insecurity by collecting and donating food and essential items, as well as packing meals that were delivered to the community. Across Mexico, teams spent time in retirement homes, donated jackets for children, and cleaned up waste from a national park. We are proud of the positive social impact our employees achieved through our Month of Giving Thanks.   1. As of December 31, 2022. 49
