## Company history

CACI traces its origins to July 17, 1962, when Herb Karr and Harry Markowitz incorporated California Analysis Center, Inc. to commercialize and teach the SIMSCRIPT simulation language. The company held its initial public offering in 1968; in its early years, it also undertook work for IBM and the U.S. Navy. [32](https://www.caci.com/sites/default/files/HistoryBookWeb/index.html)[33](https://investor.caci.com/investor-faq)

During the 1970s, CACI developed SITE, a system for analyzing U.S. Census data, and began building its Marketing Systems Group. It subsequently broadened its work in federal technology and procurement systems, and shifted toward advanced technology solutions in the 1990s. Following the September 11 attacks, national security became an increasingly central strategic focus. [34](https://www.caci.com/60years)

CACI expanded through acquisitions, including American Management Systems’ Defense and Intelligence Group in 2004, Six3 Systems in 2013, and L-3 National Security Solutions in 2016. In 2019 it completed acquisitions of Mastodon Design and LGS Innovations; later additions included SA Photonics in 2021 and ARKA Group in 2026. [35](https://www.sec.gov/Archives/edgar/data/16058/000001605804000034/ex99amsc.htm)[36](https://www.sec.gov/Archives/edgar/data/16058/000119312513445633/d630038dex991.htm)[37](https://investor.caci.com/news/news-details/2016/CACI-Completes-Strategic-Acquisition-of-L-3-National-Security-Solutions-Inc/default.aspx)[38](https://investor.caci.com/news/news-details/2019/CACI-Reports-Results-for-Its-Fiscal-2019-Third-Quarter-and-Raises-Full-Year-Net-Income-Guidance/default.aspx)[39](https://investor.caci.com/2021-11-03-CACI-Enters-Agreement-to-Acquire-SA-Photonics%2C-Inc)[40](https://investor.caci.com/2026-03-09-CACI-Completes-Acquisition-of-ARKA-Group)

Jack London led the company as president and CEO from 1984, later serving as executive chairman from 2007 to 2021. After leadership transitions in 2012 and 2013, John Mengucci became president and CEO in 2019.
