Fluor engineering is taking it in the chin in Q2 2019. I don't know about the other companies, but I know Fluor is doing a lot of mine building... I don't know about oil, but the bigger picture, it's just as the Ian Edwards said Construction companies are not doing very well(which is a bad sign, because it's a large chunk of the economic activity). -25% drop today. Very similar (although I don't know that company as well) to SNC-Lavalin: Earning loss and strategic review underway. Outlook: "Given todays announcements and the ongoing strategic review of its business and operations, the Company is withdrawing all previously issued earnings per share guidance for 2019". https://investor.fluor.com/news-releases/news-release-details/fluor-reports-second-quarter-2019-results
