BFA Law has launched a securities fraud investigation into Cardinal Infrastructure Group (NASDAQ:CDNL) over statements about the performance of its A.L. Grading Contractors acquisition. The probe follows a 36 percent stock decline on August 11 after Q2 results showed adjusted EBITDA margins well below the company's prior guidance.
A securities class-action firm is investigating whether Cardinal Infrastructure Group misled shareholders about an acquisition that preceded a 36 percent single-day collapse in the stock. Bleichmar Fonti & Auld LLP announced the probe into statements about A.L. Grading Contractors, a business the heavy construction company acquired as part of its buy-and-build strategy.
The investigation stems from Cardinal's Q2 2026 earnings report on August 11, which sent shares down $21.73 from $60.00 to $38.27 in one session. The company posted adjusted EBITDA margin of 12.4 percent, well short of the 20 percent-plus level it had guided investors to expect, blaming increased costs and scalability issues at least partially related to A.L. Grading Contractors.
Cardinal Infrastructure, which went public in December 2025 and has expanded through acquisitions, now faces potential legal action from shareholders who bought during the period in question. BFA Law, which has recovered over $900 million from Tesla's board of directors and $420 million from Teva Pharmaceutical Industries, is representing investors on a contingency fee basis with no out-of-pocket costs.
The probe adds a layer of legal risk to a stock already trading more than a third below its pre-earnings close. Potential SEC scrutiny, litigation expenses, or further disclosures about acquisition integration problems could weigh on shares. Investors will watch for Cardinal's formal response to the investigation and its next quarterly report to gauge whether margin pressures at A.L. Grading Contractors persist.
