CACI International Inc. (CACI) is making a significant bet on space-based intelligence, announcing plans to acquire ARKA Group L.P. from Blackstone Tactical Opportunities in an all-cash deal worth $2.6 billion. The move pushes CACI deeper into the national security technology space, specifically targeting capabilities that help deliver actionable intelligence to military operations.

ARKA brings something CACI doesn't currently have at scale: space-based sensors and ground software systems that support national security missions. Think satellites and the sophisticated software needed to make sense of what they're seeing. For a company already embedded in defense contracting, this acquisition accelerates CACI's ability to turn raw intelligence into something warfighters can actually use in real time.

There's a sweetener in the deal too. CACI expects to capture a tax benefit with a present value of $225 million, which helps offset some of that hefty $2.6 billion price tag. The transaction is expected to close in the third quarter of fiscal 2026, assuming it clears regulatory hurdles and other standard closing conditions.

Leadership Weighs In

Both companies are framing this as a natural fit. Andreas Nonnenmacher, ARKA's President and CEO, emphasized the cultural alignment: "Our aligned mission-focused cultures and deep engineering roots create a strong foundation for future innovation and growth, and our customers will benefit right away from the expanded capabilities of the combined company."

John Mengucci, CACI's President and CEO, highlighted ARKA's track record and Blackstone's role in developing the business: "They bring deep experience and proven performance as a best-in-class provider of national security space and defense capabilities, which has been enhanced by Blackstone's constructive stewardship of the business during their ownership."

He added, "With a shared heritage spanning more than sixty years, CACI and ARKA address complex mission requirements and deliver future-ready solutions at the speed and scale required to expand the limits of national security."

For context, CACI had $133 million in cash and cash equivalents as of September 30, so this acquisition will require substantial financing.

What the Charts Are Saying

From a technical perspective, CACI is showing some short-term weakness. The stock is currently trading 5.1% below its 20-day simple moving average and 2.4% below its 50-day SMA, suggesting it's having trouble building momentum in the near term.

The Relative Strength Index sits at 37.69, which is neutral territory. That means the stock isn't screaming overbought or oversold, leaving room for movement in either direction depending on how investors digest this acquisition news.

The MACD indicator is below its signal line, pointing to bearish momentum. Traders might want to wait for clearer signals before jumping in. Key support is pegged at $548.00, with resistance at $600.00. A move toward support could attract buyers, while breaking above resistance might signal a trend reversal.

There's a longer-term bullish signal worth noting: CACI recorded a golden cross back in June when the 50-day SMA crossed above the 200-day SMA. That typically suggests positive momentum over a longer horizon, even if recent price action has been choppy.

Zooming out, CACI has delivered a solid 38.36% gain over the past 12 months, reflecting strong demand for its defense and intelligence services. The stock is currently at 77% of its 52-week range, positioning it closer to its highs than lows. That suggests the underlying trend remains positive, even if short-term volatility persists.

Price Action: CACI International shares were up 0.57% at $556.61 at the time of publication on Monday.
