Cardinal Infrastructure Securities Investigation

Cardinal Infrastructure Group Inc. (NASDAQ: CDNL) completed a secondary public offering on June 24, 2026, selling 4.6 million shares at $73.00 per share and raising over $318 million. The company emphasized its growing project backlog, which reached $866 million as of June 30. However, on August 11, 2026, Cardinal reported Q2 2026 results showing severe margin compression: adjusted EPS fell 51% year-over-year to $0.26, missing consensus estimates of $0.47; adjusted gross margin dropped to 15.9% from 21.3%; and adjusted EBITDA margin fell to 12.4% from 18.6%. Management cut full-year 2026 adjusted EBITDA margin guidance to 16%-18% from prior guidance of greater than 20%, attributing the decline to labor shortages, expensive third-party equipment, and high subcontractor costs. Following the disclosure, Cardinal's stock plunged over 36% in a single session. Hagens Berman, a shareholder rights law firm, commenced an investigation into whether Cardinal misled investors regarding its operations and business prospects, focusing on whether the company was obligated to disclose cost pressures and equipment dependencies earlier. The firm is urging investors with losses to contact them and mentions the SEC Whistleblower program.
