CACI wins $287M Army tech contract to modernize personnel and pay system

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 surges 180% in 5 years on strong EPS growth, but weak backlog points to demand concerns

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.
