What Fluor Corp. told the SEC could break it.
Fluor's disclosures reflect an engineering-and-construction firm exposed to materials costs and a concentrated client base. Its EPC projects consume structural steel, concrete, cable and electrical and mechanical components subject to raw-material price swings in aluminum, copper, nickel and iron ore, and it flags tariffs and supply-chain disruption as a further cost risk. Its revenue leans on a few sources — a single Urban Solutions customer spanning multiple projects was 15% of 2025 revenue and U.S. government agencies were 17%, the latter bringing extensive federal procurement compliance — and its contracts can be terminated at the client's discretion, with payment only for fees earned and demobilization costs, adding backlog and revenue uncertainty.
4 self-disclosed vulnerabilities, pulled from its own filings — each in the company’s words, with the source. This is the risk register almost nobody reads.
