Oppenheimer analyst Colin Rusch raised his price target for AMSC to $16 from $10 as the company continued its "impressive" turnaround in the December quarter as it generated positive operating cash, validated growth potential in its SPS business, and successfully received the final payment from Sinovel. With management guiding to net cash of about $70M exiting the March quarter after legal fees, taxes, and capex for the SPS business, Rusch sees the company aligned for sustainable revenue growth and operating leverage. The analyst reiterates an Outperform rating on the shares.
