Greenbrier Companies Inc. (NYSE: GBX), a company engaged in the design, manufacture and marketing of railroad freight care equipment in North America and Europe, is up sharply in trading today, extending its gains from the previous trading session.

GBX had gained more than 7% on Tuesday after American Railcar Industries Inc., which is controlled by activist investor Carl Icahn, offered to acquire the company for approximately $543 per share or $20 per share. However, the offer has been rejected by GBX’s Board of Directors. The Board said that Icahn’s proposal grossly undervalues the company.
