Why is Cardinal Infrastructure Being Investigated for Securities Fraud?
Cardinal Infrastructure is a heavy construction infrastructure services company that went public in December 2025 and has grown through acquisitions.
BFA is investigating whether Cardinal misled investors about the performance of one of its acquired businesses named A.L. Grading Contractors.
Why did Cardinal Infrastructure’s Stock Drop?
On August 11, 2026, Cardinal reported Q2 2026 results. Although revenues increased year over year, the company reported adjusted EBITDA margin of only 12.4%, far below the 20%+ margin it had told investors to expect, due to increased costs and scalability issues at least partially related to A.L. Grading Contractors.
This news caused the price of Cardinal Infrastructure stock to drop $21.73 per share, or over 36%, from a closing price of $60.00 per share on August 10, 2026, to $38.27 per share on August 11, 2026, the following trading day.
