When SunEdison went through difficult layoffs in October 2015, hundreds were let go -- but the folks in the C-suite were mostly left unscathed. As GTM's Stephen Lacey reported, "The cuts have reached all the way to the VP level, but not the executive level. Sources within the company expressed worry and surprise that the cuts didn't impact the architects of the Vivint acquisition."

The other shoe has started to drop.

  • According to Julien Dumoulin-Smith at UBS, Steve Tesoriere, "an activist investor [who] played a key role in developing SunEdison’s YieldCo strategy," has resigned from the solar and wind developer's board. Tesoriere's Altai Capital Management owns approximately 2.3 percent of SunEdison, according to a proxy filing. UBS notes, "Tesoriere was also one of four to resign as a board member of SunEdison YieldCo TerraForm Power in November 2015."
  • SunEdison COO Francisco “Pancho” Perez Gundin left the company last week.
  • According to UBS, Paul Gaynor (former First Wind CEO) has also departed, although this was not disclosed in the 8K filing. "Given Paul's former role as CEO of First Wind, we continue to perceive growing risk to execution on guided targets, particularly on wind backlog," reported UBS.

Oaktree acquired asset management, operations and maintenance firm Solarrus and named Mark McLanahan as CEO. He was formerly VP of global services at SunEdison.

Gwinnell was most recently CEO of Avtron, a manufacturer of engineered equipment and components. Gwinnell replaces Tom Meola, who resigned from the company after four years as CEO. Solar FlexRack has completed more than 1 gigawatt worth of solar racking installations.       

CLEAResult, a 3,000-employee firm that designs and implements energy-efficiency programs for utilities, named Aziz Virani as its new CEO. Virani joins the company from Avanade, a technology consultancy. Prior to Avanade, Virani was a partner at Accenture. Co-founder and interim CEO Jim Stimmel will return to the executive VP position and remain on the board. CLEAResult is part of equity firm General Atlantic's portfolio.

Tom Werthan was named CFO at Phononic, a solid-state cooling and heating technology startup. Previously, Werthan was CFO at Solid State Equipment, a semiconductor capital equipment firm sold to Veeco in 2014. The near-term applications for Phononic's thermoelectrics include high-end refrigeration for labs and medical facilities, as well as cooling for fiber optics and data servers. Phononic has raised more than $85 million in funding from investors including Eastwood Capital, Wellcome Trust, Tsing Capital, Venrock, Oak Investment Partners, and Rex Health Ventures.
