Chevron warns that its $53B acquisition of Hess Corp. may be in jeopardy over key asset in Guyana

Chevron warned Monday that its pending $53 billion acquisition of Hess, another oil and gas company, may be in jeopardy because it will require the approval of Exxon Mobil and a Chinese national oil company, which both hold rights to development of an oil field off the coast of the South American nation Guyana. The disclosure in a regulatory filing raised investor qualms over the acquisition, causing shares of both Chevron and Hess to drop. Chevron shares fell 3% before rebounding; Hess shares lost 4% of their value but bounced back slightly.
