Cardinal Infrastructure, which entered the public markets in December 2025, faces claims that it failed to accurately represent the scalability and integration costs of A.L. Grading Contractors. While the company reported a year-over-year revenue increase in its Q2 2026 earnings, the adjusted EBITDA margin of 12.4% fell significantly short of the 20% benchmark previously communicated to shareholders.

The resulting market reaction was immediate. Shares dropped from $60.00 on August 10 to $38.27 the following day, wiping out over a third of the company's market value in a single session. Bleichmar Fonti & Auld is now reviewing the disclosures surrounding the acquisition to determine if these discrepancies constitute securities fraud. Investors who held stock during this period are being evaluated for potential participation in a class-action lawsuit.
