FirstNet is the only nationwide, high-speed broadband communications platform dedicated to America’s fi rst responders and public safety community. Built by AT&T in public-private partnership with the First Responder Network Authority, FirstNet covers more than 2.71 million square miles – reaching over 99% of the U.S. population. We’ve launched nearly 1,000 cell sites across the country to expand rural, remote and Tribal coverage, enabling more first responders and the communities they serve to access critical communications capabilities when needed most. For the 4th consecutive year, Frost & Sullivan has commended AT&T for innovation, market-leading performance and unmatched customer care in public safety solutions. In 2021, we earned their Public Safety Solutions Company of the Year award. FirstNet focuses on mental health By its very nature, emergency response is stressful. When we began the historic FirstNet initiative, we committed to Be There for America’s first responders. Now, we’ve established the FirstNet Health & Wellness Coalition to support their holistic health and wellness. Mental health is a key priority for AT&T and FirstNet, as the rates of PTSD, depression, anxiety – and even suicidal thought – among public safety personnel far exceed the general population. We’re supporting first responder mental health programs with organizations such as the Quell Foundation, Boulder Crest Foundation, Blue Help, the National Association of Emergency Medical Technicians and the International Association of Chiefs of Police. And we’re adding health and wellness apps to the FirstNet App Catalog. We’re committed to supporting local communities impacted by natural disasters. When disaster strikes, AT&T and employees demonstrate our corporate value Be There by assisting victims and affected communities through disaster response activities, corporate giving, volunteerism and support for impacted coworkers. AT&T is committed to working with strategic non-profit partners to provide solutions across all phases of the disaster lifecycle, including resiliency preparedness and long-term recovery. In 2021, we supported more than 200,000 individuals impacted by natural disasters such as Winter Storm Uri, historic California wildfires and the third-busiest hurricane season on record. Our community resilience efforts are motivated by our 2030 goal to help 1 million people prepare for and recover from the impacts of disasters. Progress: Help 1 million people prepare and recover by 2030 200,000 0 1,000,000 We also proactively monitor potential nature-related threats to our network, employees and communities through our Weather Operations Center. In the event of a disaster or other emergency, we implement procedures to quickly restore network functionality, provide critical resources to impacted employees, field customer inquiries and return or establish service in the communities where we operate.

Agencies using FirstNet can request a therapy dog in the same way they request a deployable network asset, such as a mobile cell site or drone, from the FirstNet fleet. And just like the fleet, the therapy dogs are available at no additional charge to support personnel on the front lines. Enhancing consumer preparedness Unless families have experienced natural disasters in the past, most are not fully prepared for an emergency. These are stressful and potentially life-threatening situations. And for vulnerable families, a crisis can destabilize their lives for years to come. Planning ahead and being prepared makes people more resilient in the face of disasters. That’s why a team of AT&T employees collaborated with non-profit SBP , a social impact organization focused on disaster resilience and recovery, to develop the Equip app. By combining easy-to-use tools, shareable resources and expert advice consolidated in one place, Equip makes it simple and engaging for households to prepare for a disaster long before it happens. We released the Equip app at the onset of the 2021 disaster season and are working with SBP to launch an awareness campaign and video tutorials to enhance the use and capacity of Equip even further.
