## Company history

ADT traces its origins to 1874, when Edward Callahan developed a telegraph-based call-box system and connected 50 homes; the American District Telegraph Company was incorporated in Baltimore that August. [7](https://www.adt.com/about-adt/history) In 2010, Tyco acquired Broadview Security and combined it with ADT’s North American security business. ADT became an independent public company in 2012 when Tyco spun it off. [31](https://www.sec.gov/Archives/edgar/data/1436040/000119312510007623/dex991.htm) [32](https://www.adt.com/content/dam/adt/downloads/about-adt/ADT_12AR_FN.pdf)

In 2016, an Apollo-affiliated transaction combined ADT with Protection 1 under the ADT brand. [33](https://investor.adt.com/News--Events/news/news-details/2016/The-ADT-Corporation-Announces-the-Closing-of-the-Previously-Announced-Transaction-with-Protection-1-an-Affiliate-of-Certain-Funds-Managed-By-Affiliates-of-Apollo-Global-Management-LLC-05-02-2016/default.aspx) ADT returned to the public markets with a 2018 IPO, the same year it acquired Aronson Security Group to expand its commercial-security business. [34](https://investor.adt.com/News--Events/news/news-details/2018/ADT-Prices-Initial-Public-Offering-01-18-2018/default.aspx) [35](https://investor.adt.com/News--Events/news/news-details/2018/ADT-Expands-Commercial-Capabilities-with-Acquisition-of-Aronson-Security-Group-ASG-03-02-2018/default.aspx)

In 2020, ADT announced a long-term smart-home security partnership with Google, which also invested $450 million in the company. [36](https://investor.adt.com/News--Events/news/news-details/2020/ADT-and-Google-Partner-To-Create-Leading-Smart-Home-Security-Offering-08-03-2020/default.aspx) [37](https://investor.adt.com/News--Events/news/news-details/2020/ADT-Announces-Closing-of-450-Million-Investment-by-Google-09-17-2020/default.aspx) ADT entered residential solar through its 2021 acquisition of Sunpro Solar, but announced its exit from that business in 2024. [38](https://investor.adt.com/News--Events/news/news-details/2021/ADT-Completes-Acquisition-of-Sunpro-Solar-12-09-2021/default.aspx) [39](https://investor.adt.com/News--Events/news/news-details/2024/ADT-Provides-Solar-Business-Update-and-Advances-Capital-Allocation-Strategy/default.aspx) In 2023, it completed the sale of its commercial security, fire and life-safety business; in 2026, it acquired Origin AI to add AI-based sensing technology.
