HC2 Holdings Inc., formerly known as Primus Telecommunications Group, Inc., is a public financial services company. The company was renamed HC2 Holdings, Inc in April 2014 after HRG Group Inc. acquired a 40.5% stake in the company, changing HC2's Stock Market ticker on the NYSE to HCHC. Since January 2014, HC2 has acquired a diverse array of operating subsidiaries, each with its own dedicated management team across a broad range of industries. This includes the acquisition of Schuff Steel, America's largest steel fabricator in the first half of 2014 and Global Marine Systems, a British company specializing in building subsea cable infrastructure in the 3rd quarter of 2014. The company divested all telecommunications interests with the exception of PTGi-ICS.
