Cardinal Infrastructure drops 36% as BFA probes A.L. Grading deal
Cardinal Infrastructure Group shares plunged 36% on Aug. 11 after Q2 margins missed guidance, drawing a securities fraud investigation from Bleichmar Fonti & Auld LLP.
The firm is examining whether Cardinal misled investors about the performance of its A.L. Grading Contractors acquisition, BFA said in a statement announcing the probe.
Cardinal, a heavy construction infrastructure services company that listed in December 2025 and expanded through acquisitions, reported Q2 2026 results on Aug. 11. Revenue rose year over year, but adjusted EBITDA margin came in at 12.4 percent, well below the 20 percent-plus the company had guided investors to expect, because of higher costs and scalability issues tied at least partly to A.L. Grading. The news erased $21.73 a share, or more than 36 percent, sending the stock from a $60.00 close on Aug. 10 to $38.27 the next trading day.
The probe adds legal risk to an acquisition-led growth strategy now under scrutiny. BFA, which recovered more than $900 million from Tesla Inc.'s board and $420 million from Teva Pharmaceutical Industries Ltd., is seeking affected Cardinal investors and represents clients on a contingency basis with no court costs passed to shareholders.
The investigation centers on statements Cardinal made about A.L. Grading's performance after the deal closed. BFA said it is looking into whether the company's disclosures about the acquired contractor were accurate as it folded the business into its operations. Investors who bought Cardinal securities are being asked to contact the firm, which has been named a top plaintiff firm by Chambers USA, The Legal 500 and ISS SCAS.
The margin shortfall is a sharp reversal for a company that built its pitch to public-market investors around steady profitability from a string of infrastructure acquisitions. A 12.4 percent adjusted EBITDA margin sits roughly 8 percentage points below the level Cardinal had told investors to expect, a gap that raises questions about how the company priced and integrated A.L. Grading.
The investigation raises the prospect of a shareholder class action and potential regulatory penalties on top of the valuation hit. Investors will watch for any restatement or further disclosure from Cardinal on A.L. Grading's integration, and for whether additional firms file suit.
