AT&T Believes SM combines our employees’ generosity of time and resources with AT&T’s longstanding external relationships, corporate contributions and foundation grants, to make a difference in our communities. In 2021, we launched AT&T Believes in Spain and Belgium, adding to more than 40 U.S. and international markets where we’re making a positive impact. We’re advancing opportunities in education, careers and quality of life through activations that help bridge the digital divide, build job skills and provide basic necessities in times of crisis. In 2022, through AT&T Believes our employees will begin tutoring and mentoring learners at AT&T Connected Learning Centers across the U.S. (page 15). Internal research shows that employees participating in volunteerism and other community engagement initiatives are more likely to recommend AT&T as a place to work, stay at AT&T longer and feel better about working for the company. We’ve set a target to engage 50% of our employees worldwide in communities through grassroots volunteerism and giving initiatives by 2030. In 2021, AT&T employees volunteered more than 443,838 hours in community outreach activities – valued at more than $12 million. 14 AT&T’s community engagement efforts and philanthropic giving – including corporate contributions and foundation grants – support initiatives that promote academic success, provide job skills training, drive innovation, empower women and underrepresented communities and respond to worldwide disasters and emergencies.

Our internal training organization, AT&T University, works across our business to create and deliver best-in-class training, helping develop diverse leadership and energize our workforce to drive innovation. We assess the effectiveness of our training initiatives by measuring employee performance and career progression, as well as our ability to fill positions internally. Our metrics show that those who take part in our training and development initiatives are: • more likely to receive a higher performance rating at the end of the year  • more likely to receive a higher key contributor award at the end of the year  • more likely to move laterally  • less likely to leave the company Targeting training to employee needs We seek innovative ways to develop our people with the right training opportunities. Our Real Time Training program delivers small-bite content to individual employees, to improve role-specific key performance indicators (KPIs). We identify who needs training and when, as well as which training solution is most likely to drive the greatest performance improvement for an employee’s respective KPIs.  In 20 21 , approximately 1,950 employees received real time tutorial recommendations, resulting in: • ~4.3K incremental new customers • ~$4.5M in incremental annual revenue Monitoring training effectiveness We monitor employee training through a platform called the Personal Learning Experience (PLE), where employees book, complete and log online courses. PLE also features a skills assessment tool to help employees identify their competencies, see what jobs are available within the company, the skills required for each position and whether demand in that particular area is projected to grow or decline in the years ahead. Training and career development Community engagement Rewarding community service AT&T applauds employees who make an outsized contribution to community engagement efforts. The President’s Volunteer Service Award (PVSA) is recognition from the President of the United States of individuals who have dedicated at least 100 hours to their communities during the year. In 2021, AT&T recognized 1,273 U.S. employees as PVSA recipients for their 2020 volunteer time. We also recognized 22 international employees who volunteered 100 hours or more in 2020.
