In a bit of a shocker, just prior to its earnings call, Enphase announced the departure of CFO Sanjeev Kumar. Like all abruptly departing CFOs, Kumar will be devoting more time to his family. Enphase announced that it beat its guidance with a $55.7 million second quarter and a 24.4 percent gross margin. The firm shipped 403,000 units this quarter, compared to 204,000 units in the second quarter of 2011. But its second-quarter net loss widened to $11.4 million -- and the markets punished Enphase for that widening loss. Enphase stock price dropped 24 percent on Wednesday of last week, hitting $5.07, close to its historical low.
