What believers are saying

  • August 2026 Q4 revenue reached $2.71 billion, with $32.0 billion backlog.
  • September 16, 2026 CENTCOM award carries a $1.5 billion ceiling and expands pipeline.
  • Fiscal 2027 guidance targets $10.65 billion to $10.85 billion revenue and $900 million cash flow.

What critics are saying

  • Nearly 83% of fiscal 2027 revenue comes from existing programs, tying growth to recompetes.
  • CACI's backlog depends on Army, CENTCOM, and OPM awards; one lost recompete hurts 2027.
  • A failed ARKA integration or fixed-price slip would crush margins and credibility.

What makes CACI unique

  • CACI pairs software-defined electronic warfare with new Rochester manufacturing for faster Army fielding.
  • ARKA adds space sensors and ground software, broadening CACI beyond services into hardware.
  • Oracle partnership on OPM HRIT modernizes federal HR on a shared cloud platform.

CACI secures USCENTCOM contract.

CACI secures USCENTCOM contract. 0 Comments On September 16, CACI International Inc announced that it has received a one-year plus four option periods award to support U.S. Central Command (USCENTCOM) and its mission partners across a demanding and rapidly changing mission environment. The award has a ceiling of $1.5 billion. "CENTCOM operates in one of the world's most challenging regions, where intelligence must move quickly from insight to action," said John Mengucci, CACI president and chief executive officer. "CACI brings the knowledge and advanced capabilities to help U.S. and partner forces act with speed, clarity, and confidence in support of our national security interests." Through Apollo, CACI will help USCENTCOM make faster decisions and coordinate more effectively across commands and partners. The company's capabilities will enhance planning, analysis, information integration, and mission execution across the command's area of responsibility. CACI will help commanders turn information into actionable insight and operate with greater confidence in contested or denied territories, allowing warfighters to out-compete adversaries in the information environment. The award builds on CACI's experience with irregular warfare missions across geographic and functional combatant commands. Under this award, CACI will apply that experience to strengthen USCENTCOM's planning, coordination, and operational readiness for its most critical mission requirements, the company said.

CACI shares jump 17% after Q2 revenue hits $2.71B, topping defence contractors

US defence contractor CACI International reported revenues of $2.71 billion for Q2, up 17.6% year on year and exceeding analyst expectations by 0.7%. The company also beat EBITDA estimates and its full-year EPS guidance surpassed analyst expectations. The stock has risen 17.2% since the earnings report and currently trades at $607.03. Defence contractors as a group had a strong quarter, with the 14 tracked companies beating revenue consensus estimates by 4% on average. However, the sector has seen share prices decline 4.4% on average since reporting. Geopolitical tensions, including Russia's invasion of Ukraine and China's aggression towards Taiwan, continue to highlight the importance of defence spending, though demand can fluctuate with defence budgets and political administrations.

CACI places new bet on growing its manufacturing chops.

CACI places new bet on growing its manufacturing chops. Stay Connected Find opportunities - and win them. By Nick Wakeman , Editor-in-Chief, Washington Technology August 21, 2026 12:47 PM ET A new facility covering 61,000 square feet is the latest step in a years-long shift from services to technology. CACI International is building out real manufacturing muscle as works to apply years of investments to transform itself from a services company to a technology-drive government contractor. That shift has been in the works for several years and the latest step is the opening of a manufacturing center in the Rochester, New York, that will focus on defense electronics. The new 61,000-square-foot facility increases CACI's manufacturing footprint by 300%, the company said. CACI has been investing in manufacturing capabilities since at least 2019, when it acquired LGS Innovations and Mastodon Design to add signal intelligence, electronic warfare and cyber products. The acquisitions provided CACI many of its earliest manufacturing capabilities. In 2024, CACI acquired Azure Summit and that added a facility in Melbourne, Florida for radio frequency and electromagnetic-spectrum hardware. CACI's late 2025 acquisition of Arka Group also added a Danbury, Connecticut hub that produces electro-optical and infrared sensors for satellites. Earlier this year, CACI hired Chris Monoski for the newly-created role of executive vice president of manufacturing. This indicates that CACI sees manufacturing as core to the business model. "Years ago, we invested in software-defined innovation because we knew the character of modern warfare was changing. Today, those investments are being transformed into advanced electronic warfare capabilities right here in Rochester," CACI President and CEO John Mengucci said. CACI's investment in the Rochester facility further emphasizes the criticality of manufacturing for the company. "As we expand our manufacturing capacity nationwide, we intentionally chose Rochester because of its exceptional talent, world-class capabilities, and longstanding community partnerships," Monoski said. "This facility reflects our long-term commitment to the region and positions us to deliver advanced capabilities faster, at greater scale, and with the quality our customers depend on." The facility will support production, delivery, training, customer acceptance testing and onsite storage for CACI's Terrestrial Layer System Brigade Combat Team Manpack (TLS BCT Manpack) program with the Army. The facility also has room for expansion that CACI can use to produce more software-defined electronic warfare capabilities at scale, the company said. "Demand for advanced electronic warfare technology is surging, and Rochester gives us the capacity to deliver for our customers today while preparing for tomorrow," said Tom Kirkland, CACI executive vice president of electronic warfare.
