Today, IEC registers THB 2,048.24 million (USD 63.14 million) in share capital. IEC has divested its retail business of distributing hand phones and consumer electronic equipment due to its high capital outlay and low margin returns. For similar reasons, IEC is also divested its MVNO (Mobile Virtual Network Operator) business of reselling cellular airtime.

Moving forward, IEC intends to specialize in technology and knowledge-driven systems integration in the Information and Communications sector, as well as in Renewable Energy.
