Cardinal Infrastructure posts Q3 loss, margin collapse and withdraws FY‑2026 guidance

Cardinal Infrastructure Group reported third‑quarter 2026 revenue of $201.9 million, up 65.1% year‑over‑year, but adjusted EBITDA margin fell to 4.2% from 17.5% a year earlier. The quarter ended with a net loss of $11.0 million and the company withdrew its full‑year 2026 revenue and margin outlook. It also postponed its planned acquisition of Hughes Brothers Construction and announced a $50 million share‑repurchase program.

The withdrawal of FY‑2026 guidance and the sharp margin decline signal heightened execution risk, which drove the stock to tumble more than 30% in pre‑market trading. The postponed acquisition reduces near‑term growth opportunities while the share‑repurchase program may provide limited support to the share price.
