In 2009, MEC had 21 factories, including 4 steel plants, a bank, a cement plant and an insurance monopoly. Its headquarters are located on Ahlon Road in Yangon's Ahlon Township. MEC has remained on the United States' list of sanctioned companies due to its affiliation to the Burmese military. MEC also operates Innwa Bank, one of Burma's few banking chains. A subsidiary of MEC, Star High Public Company, owns 28% of Mytel, one of Myanmar's largest telecommunications company, in a joint venture with Viettel.
MEC is operated under the Ministry of Defence's Directorate of Defence Procurement (DPP), with its private shares exclusively owned by active-duty military personnel.
The corporation's capital was established through revenues generated from the public auctioning of state-owned enterprises throughout the 1990s. Through joint ventures with foreign companies and mergers with smaller companies, MEC has positioned itself as one of Burma's largest corporations.
In 2000, MEC launched Cybermec Information Technology Center, an IT venture.
