AR KA, AR K A-Plus: CACI’s Q3 2026 Results Signal Growth Pace as ARKA Acquisition Lands

Quarterly results at a glance

In the three months ended March 31, 2026, CACI toplined $2,351.0 million, up from $2,167.0 million a year earlier — a clean 8.5% year-over-year lift.

Net income came in at $130.4 million, producing a diluted EPS of $5.88, up 17.6% YoY.

On an adjusted basis, net income was $161.1 million, with adjusted diluted EPS of $7.27, up 16.7% YoY.

EBITDA reached $289.7 million and delivered an EBITDA margin of 12.3%, noting $17.4 million of ARKA-related transaction expenses within that figure.

Income from operations stood at $228.9 million, compared with $196.4 million in the prior-year quarter.

Strategic moves behind the numbers

The ARKA Group acquisition has closed, described by CACI as a meaningful strategic step to broaden capabilities serving customers’ most critical missions in high-growth, high-demand markets. Management is raising the full-year revenue forecast and EBITDA margin guidance to reflect the ARKA addition, while specifically noting that free cash flow guidance remains intact even as ARKA-related costs are absorbed.

CEO John Mengucci framed the quarter as evidence of the company’s disciplined strategy: “we are raising our full year revenue guidance to reflect the addition of ARKA, and raising our EBITDA margin guidance to reflect the stronger performance of our organic business. In addition, we are reaffirming our free cash flow guidance even as we absorb additional costs from the ARKA transaction.”

Implications for CACI and sector peers

The quarter reads like a validation of growth through targeted acquisitions paired with solid core execution. The ARKA contribution appears to lift top-line growth while the adjusted EPS shows meaningful accretion, even after accounting for transaction expenses. For investors, the key question is how sustainable the ARKA uplift will be as the integration proceeds and as new contracts begin to contribute beyond the initial period.

From a sector lens, CACI’s move underscores a continued appetite for M&A among government IT services players, particularly when deals promise capability expansion in defense and intelligence domains. If the integration proves smoother than the common worry about “-merger integration drag,” rivals may accelerate their own consolidation or lift investment in cross-selling across contract vehicles. In short, trends seen in CACI’s quarterly results could ripple through peers such as Leidos, ManTech, and other mid-cap government-services outfits as they calibrate growth trajectories against a backdrop of stable federal funding and ongoing demand for digital and mission-critical capabilities.
