Matrix is often regarded as a mining services company, but could easily be classified under technology, with one of the most advanced manufacturing facilities in the world.

It specialises in producing sub-sea buoyancy equipment for deep sea oil rigs, and in producing other such "consumables" for oil and gas production and exploration.

This technology is very specialised, which means there are significant barriers to entry. It has only two competitors in the offshore drilling space. But against this competitive advantage, it is facing industry pressures resulting from the oil price decline.
