Company News
CACI International has secured a seven-year $287 million contract to modernise the US Army's Integrated Personnel and Pay System-Army, supporting over one million users. The company also confirmed its optical communications hardware played a central role in NASA's Artemis II mission. The defence technology contractor is scheduled to release Q3 FY2026 earnings on 22 April, with consensus expecting mid-single to low-double digit revenue and earnings growth. Analysts project CACI could reach $10.9 billion in revenue and approximately $684 million in earnings by 2028. The contract reinforces CACI's position as a federal technology partner in defence and space programmes, though the company remains heavily reliant on US government budgets. The investment narrative centres on execution of large, high-value contracts whilst managing federal spending exposure.
CACI International has contributed optical communications and sensing technology to NASA's Artemis II mission, the first crewed flight of the Space Launch System rocket and Orion spacecraft. The company developed an optical communications modem module in partnership with MIT Lincoln Laboratory, integrated into the Orion Artemis II Optical Communications System payload. The O2O system successfully delivered high-definition video and data from the lunar vicinity to Earth via laser link, marking a milestone in deep-space communications. Through its acquisition of ARKA Group, CACI also supplied cryogenic-level sensing technology for the SLS rocket, supporting propellant-level measurement and engine shutdown determination during ascent. CACI's hardware is developed across multiple US locations, including Danbury, Connecticut, and Florham Park, New Jersey.

The notes will be issued as part of the same series as CACI's 6.375% senior notes originally issued in June 2025.

CACI International, a defence and intelligence solutions provider, has surged 180% over the past five years, reaching $630.12 per share and outperforming the S&P 500's 72.6% total return. The stock has gained 29.6% in the last six months. The company demonstrated solid long-term performance with revenue growing at 8.8% compound annual growth rate over five years. More impressively, earnings per share expanded at 14% annually, indicating improved profitability. However, CACI's backlog growth has been weak, averaging just 3.6% year-on-year over the last two years. This underwhelming performance suggests increasing competition may be challenging the company's ability to secure new orders. The stock currently trades at 20.6× forward price-to-earnings ratio.
