Letter from our Chief Executive Officer We’re at the dawn of a new era of connectivity, one which we believe represents an opportunity to make positive and lasting contributions to the world around us. To deliver on that promise and maximize our performance as a company, we actively monitor and adjust the way our operations intersect with the environment and society, and work to effectively manage those impacts. This report illustrates how AT&T is enhancing our resilience and supporting our stakeholders by addressing leading environmental, social and governance (ESG) issues. For example: • Our employees tell us they want their work to serve others in a meaningful way. There’s perhaps no better model than our belief in internet for all and our pledge to help the millions of Americans who still cannot access or afford fast, reliable connectivity. Our efforts include advocating for thoughtful governmental policies and strategically deploying our $2 billion commitment to help close the digital divide – which includes broadening our low-cost connectivity offerings and launching AT&T Connected Learning SM resources across the country. • AT&T has set an industry-leading target to help businesses collectively reduce a gigaton of greenhouse gas (GHG) emissions by 2035 – equivalent to roughly 15% of all 2020 U.S. GHG emissions. We’ve established a Connected Climate Initiative to advance this effort alongside talented business, research and community leaders. And we’re executing plans to aggressively reduce our own operational emissions, to be carbon neutral by 2035. • As we continue to work toward a more equitable society, I’m proud that AT&T has been recognized for our efforts to build a company culture where every employee is treated with fairness and provided equal opportunities to advance. But there is always more we can do, which is why we now make public our traditional measurements of workforce demographic data and are looking to our senior leaders to help improve diverse representation across all levels. I invite you to read on and learn more about our ESG focus areas and commitments, how these efforts are creating long-term value across our operations and how we’re positively impacting the lives of others and the environment around us.
