Mixed FQ4 results and light guidance lead American Superconductor (AMSC -10.6%) to tumble towards its 52-week low of $2.30. The superconductor/wind turbine parts maker expects FQ1 revenue to exceed $22M and EPS to be better than -$0.26; the consensus is at $24.1M and -$0.18. FQ4 gross margin was 11.1%, +600 bps Q/Q but -130 bps Y/Y. Wind division sales -47% Y/Y (were -33% in FQ3), grid division -3% (a big reversal from FQ3's +34%). R&D spend -35% Y/Y to $3.8M, SG&A -23% to $13.3M. (PR)
