Elder Guard Industries was not always a conglomerate. It started of it's life as a capsule retrofitter, reworking old ships to work with capsules. It wasn't soon after that they started producing their own ships along with their retrofitting.

As the ever rising prices of materials began to dwindle on profits, it became increasingly clear that they needed to branch into another industry.

Taking knowledge they had gained from observing the caldari corperations, they found Inner Circle Exhuming, a startup mining company.

Soon there after they brought Titan's Fist Munitions, and their partner Soul Bound Armaments. Others where soon to follow. All being brought under the Elder Guard Industries banner.

Whats interesting is the take on conglomerate that EGI had. Other than a few minor changes, and a couple of EGI Employees to oversee things, they were largely left to their own devices.

Just recently having put themselves on the market for capsuleer members, they don't have much of a footprint in the world of EVE. But if history has a way of repeating itself, then that shouldn't be much of a problem.
