Investigative Firm Probes Cardinal Infrastructure Group For Potential Securities Fraud

NEW YORK, Sept. 3, 2026 /CourierPR/ -- Investigative law firm Pomerantz LLP is currently probing potential securities fraud allegations involving Cardinal Infrastructure Group Inc. ("Cardinal"), a company listed on the NASDAQ under the ticker symbol CDNL.

The investigation centers on whether Cardinal and certain of its executives or board members engaged in illegal business practices, including possible securities fraud. This comes after Cardinal recently disclosed significant financial setbacks, including a drastic drop in its adjusted EBITDA margin.

On August 11, 2026, Cardinal announced that its adjusted EBITDA margin had declined from 18.6% in the prior year to 12.4%. This news prompted the company to revise its full-year adjusted EBITDA margin guidance downward to 16-18%, from an earlier expectation of more than 20%. The revelation was made shortly after Cardinal completed a follow-on equity offering in June 2026.

In response to this news, Cardinal's stock price plummeted, losing $21.73 per share, or 36.22%, to close at $38.27 per share on the same day.
