A Growth Story Turns Into a Margin Problem

Cardinal Infrastructure Group (NASDAQ:CDNL) was the worst performer on the November 12 losers screen after its third-quarter report showed that rapid revenue growth had not translated into profit. The North and South Carolina contractor installs water, sewer and stormwater systems and handles site development work such as grading, clearing, blasting and paving for residential, commercial and public clients. Revenue climbed 65.1% to USD 201.9 million, helped by USD 55.7 million from acquisitions and USD 23.9 million of organic growth, yet it still fell well short of forecasts near USD 235 million. Cost of revenue rose 85.8% to USD 191.1 million, leaving a gross margin of just 5.4%. The company booked a USD 13.2 million reduction to gross profit from revised project estimates, while residential pricing pressure, lower bid margins and higher fuel and transport costs each took several points off margin. Chief executive Jeremy Spivey said the quarterly margin was well below expectations.

Guidance Pulled and Leadership Changes

The more damaging step for confidence was the Withdrawal of full-year 2026 revenue and adjusted EBITDA margin guidance, with no replacement range offered beyond an expectation that fourth-quarter adjusted EBITDA will improve on the third quarter. Adjusted EBITDA fell 60.3% to USD 8.5 million, a 4.2% margin against 17.5% a year earlier, and general and administrative costs rose 187.0% to USD 14.7 million. The board postponed the proposed Acquisition of Hughes Brothers, gave the chief operating officer a more direct operating role and plans to hire an independent adviser to review estimating and project processes. Chief financial officer Mike Rowe told the company on November 9 that he will resign once a successor is found. A plaintiff law firm also announced on November 11 that it is investigating disclosures about an earlier acquisition, tied to a 36% drop in August after second-quarter results. No lawsuit has been filed on that basis so far.

Balance Sheet Support and Valuation

The Balance Sheet gives the company room to fix execution. At September 30, 2026, cash stood at USD 335.0 million against total Debt of USD 198.5 million, leaving net cash of USD 136.5 million, with an undrawn USD 100 million revolver and a USD 250 million delayed draw term loan. Backlog rose 26.2% to USD 815.5 million, and the board authorised up to USD 50 million of share repurchases over 12 months. At USD 6.03, the shares trade at about 4.95 times trailing diluted Earnings of USD 1.22, and the Market Value has fallen to roughly USD 711.62 million. That multiple reflects heavy doubt that past earnings are repeatable. Through nine months, Net Income was USD 11.7 million, down 55.5%, and free Cash Flow was negative at USD 11.3 million, so investors will want proof that bid discipline and cost control can restore double-digit margins before the low multiple looks like value.

Where Things Stand

Cardinal Infrastructure Group (NASDAQ:CDNL) fell 59.77% to USD 6.03 on November 12, 2026 after a third-quarter net loss of USD 11.0 million, a 5.4% gross margin and the withdrawal of full-year guidance. Revenue growth of 65.1%, net cash of USD 136.5 million, a USD 815.5 million backlog and a new USD 50 million buyback offer support, but credibility on project estimates must be rebuilt first.
