Cardinal Infrastructure Group Inc. reported strong growth for the three months ended March 31, 2026, driven by acquisitions and backlog. Revenue rose to $167.5 million from $81.8 million, while net income increased to $11.5 million, though income attributable to Cardinal Infrastructure was $3.4 million versus $5.5 million a year earlier due to a larger noncontrolling interest.
The company closed the ALGC acquisition with total consideration of about $254.7 million, including substantial rollover equity and cash largely funded by an additional $80 million term loan. This lifted total assets to $657.3 million and notes payable to $198.6 million, and added $105.1 million of goodwill and significant new intangible assets.
Cardinal also changed its depreciation method to straight-line, boosting pre-tax income by about $0.6 million and EPS by $0.03 in the quarter. Remaining performance obligations reached $524.0 million, largely expected to convert to revenue within 18 months, underscoring a sizable contracted backlog across its Southeast U.S. infrastructure markets.
