SHINE Medical Technologies and Phoenix have completed a merger under which Phoenix has become a wholly owned subsidiary of SHINE, the companies announced today.

“SHINE and Phoenix have shared a common long-term vision and operated in close collaboration during the past 11 years, but it’s always been inefficient to operate as separate companies,” SHINE CEO Greg Piefer said in a statement. “Coming together will enable us to advance fusion technology more quickly by aligning interests and combining complementary core competencies.”

Piefer founded Phoenix in 2005 and spun SHINE out of it in 2010. 

According to a release, the two companies will focus on clean energy production through a four-phase progression.
