Zoltek (ZOLT -11.2%) gets hammered today after its Q4 earnings missed consensus across the board, as total sales plummeted by 23% Y/Y. The company cites a near-shut-down of business in Europe during the second half of December, coupled an acceleration in production by its U.S. wind turbine customers during the first three calendar quarters, to assure completion of capital projects by the end of the year in order to benefit from the US tax credits.
