The scrutiny follows Cardinal’s August 11, 2026, second-quarter earnings report. While the heavy construction firm posted revenue growth, its adjusted EBITDA margin hit only 12.4%—a sharp miss compared to the 20% target previously communicated to investors. Management attributed the shortfall to escalating costs and scalability challenges tied to the A.L. Grading Contractors unit.

Market reaction was immediate. Shares of Cardinal (NASDAQ: CDNL) plummeted from a $60.00 close on August 10 to $38.27 the following day, wiping out significant investor value. BFA Law is now reviewing whether these financial discrepancies constitute securities fraud. Investors impacted by the decline are invited to contact the firm to discuss potential litigation options, with all legal representation handled on a contingency fee basis.
