Traxus Heavy Industries
From Halopedia, the Halo wiki
Not much is known about Traxus,[1] other than it's name. It is a human company probably based on Earth. There are several windows in Wind Power Station 7 on Zanzibar Island with this word (possibly the name of an Earth company) written on them, with "09" written underneath in smaller lettering. In the Halo 3 E3 2007 Trailer, Traxus has been seen on the cargo crates similar to the way COBB Industries was refrenced on crates in Halo 2.
Part of Halo 3's campaign will take place in the Traxus compound.
Trivia
This is a reference to Traxus IV, an AI that went rampant in the Marathon series.
